    cMsg is software used to send and receive messages in the Jefferson Lab online and runcontrol systems. It was created to replace the several IPC software packages in use with a single API. cMsg is asynchronous in nature, running a callback for each message received. However, it also includes synchronous routines for convenience. On the framework level, cMsg is a thin API layer in Java, C, or C++ that can be used to wrap most message-based interprocess communication protocols. The top layer of cMsg uses this same API and multiplexes user calls to one of many such wrapped protocols (or domains) based on a URL-like string which we call a Uniform Domain Locator or UDL. One such domain is a complete implementation of a publish-subscribe messaging system using network communications and written in Java (user APIs in C and C++ too). This domain is built in a way which allows it to be used as a proxy server to other domains (protocols). Performance is excellent allowing the system not only to be used for messaging but also as a data distribution system.

    Farms Batch System (FBS) was developed as a batch process management system for off-line Run II data processing at Fermilab. FBS will manage PC farms composed of up to 250 nodes and scalable to 1000 nodes with disk capacity of up to several TB. FBS allows users to start arrays of parallel processes on multiple computers. It uses a simplified resource counting method load balancing. FBS has been successfully used for more than a year at Fermilab by fixed target experiments and will be used for collider experiment off-line data processing. Fermi Inter-Process Communication toolkit (FIPC) was designed as a supplement product for FBS that helps establish synchronization and communication between processes running in a distributed batch environment. However, FIPC is an independent package, and can be used with other batch systems, as well as in a non-batch environment. FIPC provides users with a variety of global distributed objects such as semaphores, queues and string variables. Other types of objects can be easily added to FIPC. FIPC has been running on several PC farms at Fermilab for half a year and is going to be used by CDF for off-line data processing.

    2005-01-01

    In resource-poor developing countries, significant improvements in child survival, growth, and development can be made by: (a) shifting from sectoral programmes (for example, in nutrition or immunization) to holistic strategies such as the Integrated Management of Childhood Illnesses (IMCI) and (b) improving household and community care and health-seeking practices as a priority, while concurrently strengthening health systems and the skills of health professionals. This article focuses on household and community learning, and proposes a communication strategy for implementing community IMCI (c-IMCI) that is based on human rights principles such as inclusion, participation, and self-determination. Rather than attempt to change the care practices and health-seeking behaviour of individuals through the design and delivery of messages alone, it proposes an approach that is based on community engagement and discussion to create the social conditions in which individual change is possible. The strategy advocates for the integration of sectoral programmes rather than the development of new holistic programmes, so that integrated programmes are created from "multiple entry points". As integration occurs, the participatory communication processes that are used in sectoral programmes can be enriched and combined, improving the capacity of governments and agencies to engage community members effectively in a process of learning and action related to child health and development.

    Programming languages are the most important tool at a programmers' disposal. All other tools correct, visualize, or evaluate the product crafted by this tool. The advent of multiprocessor computer systems has greatly complicated the programmer's task an increased his need for high-level languages capable of automatically taming these architectures. In this paper, we describe a prototype implementation of Sisal for multiprocessor, hierarchical-memory systems. The implementation includes explicit compiler and runtime control that effectively exploits the different levels of memory and manages interprocess communications (IPC). We give preliminary performance results for this system on the BBN TC2000.

    The Idaho National Engineering and Environmental Laboratory (INEEL) received ISO 14001/EMS certification in June 2002. Communication played an effective role in implementing ISO 14001/EMS at the INEEL. This paper describes communication strategies used during the implementation and certification processes. The INEEL achieved Integrated Safety Management System (ISMS) and Voluntary Protection Program (VPP) Star status in 2001. ISMS implemented a formal process to plan and execute work. VPP facilitated worker involvement by establishing geographic units at various facilities with employee points of contact and management champions. The INEEL Environmental Management System (EMS) was developed to integrate the environmental functional area into its ISMS and VPP. Since the core functions of ISMS, VPP, and EMS are interchangeable, they were easy to integrate. Communication is essential to successfully implement an EMS. (According to ISO 14001 requirements, communication interacts with 12 other elements of the requirements.) We developed communication strategies that integrated ISMS, VPP, and EMS. For example, the ISMS, VPP, and EMS Web sites communicated messages to the work force, such as “VPP emphasizes the people side of doing business, ISMS emphasizes the system side of doing business, and EMS emphasizes the systems to protect the environment; but they all define work, identify and analyze hazards, and mitigate the hazards.” As a result of this integration, the work force supported and implemented the EMS. In addition, the INEEL established a cross-functional communication team to assist with implementing the EMS. The team included members from the Training and Communication organizations, VPP office, Pollution Prevention, Employee and Media Relations, a union representative, facility environmental support, and EMS staff. This crossfunctional team used various communication strategies to promote our EMS to all organization levels and successfully implemented EMS

  12. An implementation-independent threat model for group communications

    Hester, Jason; Yurcik, William; Campbell, Roy

    2006-04-01

    The importance of group communications and the need to efficiently and reliably support it across a network is an issue of growing importance for the next decade. New group communication services are emerging such as multimedia conferencing/groupware, distributed interactive simulations, sensor fusion systems, command and control centers, and network-centric military applications. While a succession of point-to-point unicast routes could provide group communications, this approach is inherently inefficient and unlikely to support the increased resource requirements of these new services. There is the lack of a comprehensive process to designing security into group communications schemes. Designing such protection for group communications is best done by utilizing proactive system engineering rather than reacting with ad hoc countermeasures to the latest attack du jour. Threat modeling is the foundation for secure system engineering processes because it organizes system threats and vulnerabilities into general classes so they can be addressed with known protection techniques. Although there has been prior work on threat modeling primarily for software applications, however, to our knowledge this is the first attempt at implementation-independent threat modeling for group communications. We discuss protection challenges unique to group communications and propose a process to create a threat model for group communication systems independent of underlying implementation based on classical security principles (Confidentiality, Integrity, Availability, Authentication, or CIAA). It is our hope that this work will lead to better designs for protection solutions against threats to group communication systems.

    The communication campaign for Rosetta has been the biggest success in the history of European Space Agency outreach, resulting in global awareness for the agency. The mission itself is an extraordinary operational and scientific success, but communicating only the operational and scientific firsts would likely not have brought the Rosetta orbiter and Philae lander to the attention of so many people, and would not have made the mission part of people's lives across the globe. The additional impact brought to the mission through the communication campaign was based on a strategic approach focusing on: real-time release of information with maximum transparency; direct real-time access for media and social media; adding a human dimension to the story; and communicating the risks openly in order to manage expectations. In this article we describe our overall strategy, illustrate its implementation, and provide the framework for subsequent articles in this journal highlighting specific aspects of the campaign in more detail.

    The Hermes (CTS) experiment program made possible a significant effort directed toward new developments which will reduce the costs associated with the distribution of satellite services. Advanced satellite transponder technology and small inexpensive earth terminals were demonstrated as part of the Hermes program. Another system element that holds promise for reduced transmission cost is associated with the communication link implementation. An experiment is described which uses CTS to demonstrate digital link implementation and its advantages over conventional analog systems. A Digitally Implemented Communications experiment which demonstrates the flexibility and efficiency of digital transmission of television video and audio, telephone voice and high-bit-rate data is also described. Presentation of the experiment concept which concentrates on the evaluation of full-duplex digital television in the teleconferencing environment is followed by a description of unique equipment that was developed.

    The public concern about electromagnetic field (EMF) exposure varies due to different reasons. A part of them are connected with the better and higher quality of information that people receive from science, media, Internet, social networks, industry, but others are based on good communication programs performed by the responsible institutions, administration and persons. Especially, in Bulgaria, public concern follows interesting changes, some of them in correlation with the European processes of concern, but others following the economic and political processes in the country. Here, we analyze the dynamics of the public concern over the last 10 years. Our explanation of the decrease of the people's complaints against EMF exposure from base stations for mobile communication is as a result of our risk communication program that is in implementation for >10 years.

    The commuter and freight railroad industry is required to implement Positive Train Control (PTC) by 2015 (2012 for Metrolink), a challenging network communications problem. This paper will discuss present technologies developed by the National Aeronautics and Space Administration (NASA) to overcome comparable communication challenges encountered in deep space mission operations. PTC will be based on a new cellular wireless packet Internet Protocol (IP) network. However, ensuring reliability in such a network is difficult due to the "dead zones" and transient disruptions we commonly experience when we lose calls in commercial cellular networks. These disruptions make it difficult to meet PTC s stringent reliability (99.999%) and safety requirements, deployment deadlines, and budget. This paper proposes innovative solutions based on space-proven technologies that would help meet these challenges: (1) Delay Tolerant Networking (DTN) technology, designed for use in resource-constrained, embedded systems and currently in use on the International Space Station, enables reliable communication over networks in which timely data acknowledgments might not be possible due to transient link outages. (2) Policy-Based Management (PBM) provides dynamic management capabilities, allowing vital data to be exchanged selectively (with priority) by utilizing alternative communication resources. The resulting network may help railroads implement PTC faster, cheaper, and more reliably.

  20. Communication and implementation of change in crop protection.

    1993-01-01

    The slow adoption of integrated pest management (IPM) has been attributed to the widespread gaps in farmers' knowledge of rational pest management. Other factors such as farmers' perception of high input use and promotion of pesticides also influence decisions to practise rational pest management. To bridge these gaps and improve farmers' pest management practices, most IPM implementation programmes rely on communication strategies. These communication approaches utilize either mass media or interpersonal channels or a combination. The choice of which communication approach to employ depends on project objectives and resources. Among extension and communication approaches used in crop protection, strategic extension campaigns, farmer field schools and farmer participatory research stand out in their ability to bring about significant changes in farmers' pest management practices. While extension campaigns have greater reach, farmer participation and experiential learning achieve more impact because learning effects are sustained. Communication media are important in raising awareness and creating a demand for IPM information but interpersonal channels and group methods such as the farmer field school and farmer participatory research are essential to accomplish the tasks of discovery and experiential learning of IPM skills.

  2. Aspects of implementing and harmonizing healthcare communication standards.

    1998-02-01

    A variety of healthcare communication standards (HCS) have been developed during the last decade. They have improved the interoperability and the connectivity in open hospital information systems to a large extent. They have also reduced time and efforts during the implementation of standard interfaces. However, the implementation of communication standards is still far from the expected plug and play. The two reasons which are the main cause the current drawbacks are identified--the lack of a standardized terminology and the restricted flexibility of the currently used interchange formats. On the one hand the standardization of the terminology can not be solved by the standards development organizations. It is a general challenge for the medical informatics community. On the other hand the movement to a new interchange format can be initiated by standards development organizations. The application of SGML/XML as an interchange format for communication standards offers a much greater flexibility and adaptability to user needs than the currently used interchange formats. Concepts for a smooth change to a new direction are discussed. PMID:9600416

    1994-01-01

    Software-implemented fault tolerance (SIFT) is used in many computer-based command, control, and communications (C(3)) systems to provide the nearly continuous availability that they require. In the communications subsystem of Space Station Alpha, SIFT algorithms are used to detect and recover from failures in the data and command link between the Station and its ground support. The paper presents a review of these algorithms and discusses how such techniques can be applied to similar systems found in applications such as manufacturing control, military communications, and programmable devices such as pacemakers. With support from the Tracking and Communication Division of NASA's Johnson Space Center, researchers at the University of Wyoming are developing a testbed for evaluating the effectiveness of these algorithms prior to their deployment. This testbed will be capable of simulating a variety of C(3) system failures and recording the response of the Space Station SIFT algorithms to these failures. The design of this testbed and the applicability of the approach in other environments is described.

    1976-01-01

    Possible implementations and recommendations for the Space Shuttle Ku-Band integrated communications/radar antenna tracking system were evaluated. Communication aspects involving the Tracking Data Relay Satellite (TDRS)/Orbiter Ku-Band link are emphasized. Detailed analysis of antenna sizes, gains and signal-to-noise ratios shows the desirability of using maximum size 36-inch diameter dish and a triple channel monopulse. The use of the original baselined 20 inch dish is found to result in excessive acquisition time since the despread signal would be used in the tracking loop. An evaluation of scan procedures which includes vehicle dynamics, designation error, time for acquisition and probability of acquisition shows that the conical scan is preferred since the time for lock-on for relatively slow look angle rates will be significantly shorter than the raster scan. Significant improvement in spherical coverage may be obtained by reorienting the antenna gimbal to obtain maximum blockage overlap.

    2016-04-01

    The paper presents software implementation of a receiver forming a part of an adaptive communication system. The system is intended for communication with a satellite placed in a low Earth orbit (LEO). The ability of adaptation is believed to increase the total amount of data transmitted from the satellite to the ground station. Depending on the signal-to-noise ratio (SNR) of the received signal, adaptive transmission is realized using different transmission modes, i.e., different modulation schemes (BPSK, QPSK, 8-PSK, and 16-APSK) and different convolutional code rates (1/2, 2/3, 3/4, 5/6, and 7/8). The receiver consists of a software-defined radio (SDR) module (National Instruments USRP-2920) and a multithread reception software running on Windows operating system. In order to increase the speed of signal processing, the software takes advantage of single instruction multiple data instructions supported by x86 processor architecture.

    1993-07-01

    Facilities such as interprocess communication and protection of shared resources have been added to operating systems to support multiprogramming and have since been adapted to exploit explicit multiprocessing within the scope of two models: the shared-memory model and the distributed (message-passing) model. When multiprocessors (or networks of heterogeneous processors) are used for explicit parallelism, the difference between these models is exposed to the programmer. The p4 tool set was originally developed to buffer the programmer from synchronization issues while offering an added advantage in portability, however two models are often still needed to develop parallel algorithms. We provide two implementations of Linda in an attempt to support a single high-level programming model on top of the existing paradigms in order to provide a consistent semantics regardless of the underlying model. Linda`s fundamental properties associated with generative communication eliminate the distinction between shared and distributed memory.

    In the cable network services, the audio/video entertainment contents should be protected from unauthorized copying, intercepting, and tampering. Point-of-deployment (POD) security module, proposed by[InlineEquation not available: see fulltext.], allows viewers to receive secure cable services such as premium subscription channels, impulse pay-per-view, video-on-demand as well as other interactive services. In this paper, we present a digital signal processor (DSP) (TMS320C6211) based POD implementation for the real-time applications which include elliptic curve digital signature algorithm (ECDSA), elliptic curve Diffie Hellman (ECDH) key exchange, elliptic curve key derivation function (ECKDF), cellular automata (CA) cryptography, communication processes between POD and Host, and Host authentication. In order to get different security levels and different rates of encryption/decryption, a CA based symmetric key cryptography algorithm is used whose encryption/decryption rate can be up to[InlineEquation not available: see fulltext.]. The experiment results indicate that the DSP based POD implementation provides high speed and flexibility, and satisfies the requirements of real-time video data transmission.

    Abstract Problem Bangladesh has yet to develop a fully integrated health information system infrastructure that is critical to guiding policy development and planning. Approach Initial pilot telemedicine and eHealth programmes were not coordinated at national level. However, in 2011, a national eHealth policy was implemented. Local setting Bangladesh has made substantial improvements to its health system. However, the country still faces public health challenges with limited and inequitable access to health services and lack of adequate resources to meet the demands of the population. Relevant changes In 2008, eHealth services were introduced, including computerization of health facilities at sub-district levels, internet connections, internet servers and an mHealth service for communicating with health-care providers. Health facilities at sub-district levels were provided with internet connections and servers. In 482 upazila health complexes and district hospitals, an mHealth service was set-up where an on-duty doctor is available for patients at all hours to provide consultations by mobile phone. A government operated telemedicine service was initiated and by 2014, 43 fully equipped centres were in service. These centres provide medical consultations by qualified physicians to patients visiting rural and remote community clinics and union health centres. Lessons learnt Despite early pilot interventions and successful implementation, progress in adopting eHealth strategies in Bangladesh has been slow. There is a lack of common standards on information technology for health, which causes difficulties in data management and sharing among different databases. Limited internet bandwidth and the high cost of infrastructure and software development are barriers to adoption of these technologies. PMID:26549909

    1990-08-01

    The Department of Radiological Sciences at the UCLA School of Medicine is developing an archiving and communication system (PACS) for digitized ultrasound images. In its final stage the system will involve the acquisition and archiving of ultrasound studies from four different locations including the Center for Health Sciences, the Department for Mental Health and the Outpatient Radiology and Endoscopy Departments with a total of 200-250 patient studies per week. The concept comprises two stages of image manipulation for each ultrasound work area. The first station is located close to the examination site and accomodates the acquisition of digital images from up to five ultrasound devices and provides for instantaneous display and primary viewing and image selection. Completed patient studies are transferred to a main workstation for secondary review, further analysis and comparison studies. The review station has an on-line storage capacity of 10,000 images with a resolution of 512x512 8 bit data to allow for immediate retrieval of active patient studies of up to two weeks. The main work stations are connected through the general network and use one central archive for long term storage and a film printer for hardcopy output. First phase development efforts concentrate on the implementation and testing of a system at one location consisting of a number of ultrasound units with video digitizer and network interfaces and a microcomputer workstation as host for the display station with two color monitors, each allowing simultaneous display of four 512x512 images. The discussion emphasizes functionality, performance and acceptance of the system in the clinical environment.

    2011-07-01

    Increasingly, total maximum daily load (TMDL) limits are being defined for agricultural watersheds. Reductions in non-point source pollution are often needed to meet TMDL limits, and improvements in management of annual crops appear insufficient to achieve the necessary reductions. Increased adoption of perennial crops and other changes in agricultural land use also appear necessary, but face major barriers. We outline a novel strategy that aims to create new economic opportunities for land-owners and other stakeholders and thereby to attract their voluntary participation in land-use change needed to meet TMDLs. Our strategy has two key elements. First, focused efforts are needed to create new economic enterprises that capitalize on the productive potential of multifunctional agriculture (MFA). MFA seeks to produce a wide range of goods and ecosystem services by well-designed deployment of annual and perennial crops across agricultural landscapes and watersheds; new revenue from MFA may substantially finance land-use change needed to meet TMDLs. Second, efforts to capitalize on MFA should use a novel methodology, the Communicative/Systemic Approach (C/SA). C/SA uses an integrative GIS-based spatial modeling framework for systematically assessing tradeoffs and synergies in design and evaluation of multifunctional agricultural landscapes, closely linked to deliberation and design processes by which multiple stakeholders can collaboratively create appropriate and acceptable MFA landscape designs. We anticipate that application of C/SA will strongly accelerate TMDL implementation, by aligning the interests of multiple stakeholders whose active support is needed to change agricultural land use and thereby meet TMDL goals.

Reductions in non-point source pollution are often needed to meet TMDL limits, and improvements in management of annual crops appear insufficient to achieve the necessary reductions. Increased adoption of perennial crops and other changes in agricultural land use also appear necessary, but face major barriers. We outline a novel strategy that aims to create new economic opportunities for land-owners and other stakeholders and thereby to attract their voluntary participation in land-use change needed to meet TMDLs. Our strategy has two key elements. First, focused efforts are needed to create new economic enterprises that capitalize on the productive potential of multifunctional agriculture (MFA). MFA seeks to produce a wide range of goods and ecosystem services by well-designed deployment of annual and perennial crops across agricultural landscapes and watersheds; new revenue from MFA may substantially finance land-use change needed to meet TMDLs. Second, efforts to capitalize on MFA should use a novel methodology, the Communicative/Systemic Approach (C/SA). C/SA uses an integrative GIS-based spatial modeling framework for systematically assessing tradeoffs and synergies in design and evaluation of multifunctional agricultural landscapes, closely linked to deliberation and design processes by which multiple stakeholders can collaboratively create appropriate and acceptable MFA landscape designs. We anticipate that application of C/SA will strongly accelerate TMDL implementation, by aligning the interests of multiple stakeholders whose active support is needed to change agricultural land use and thereby meet TMDL goals.

It is intended to support multiple upper layer protocol (ULPs) or programming models including SHMEM,UPC,Titanium,Co-Array Fortran,Global Arrays,MPI,GASNet, and File I/O. it provides various communication operations including one-sided and two-sided point-to-point, collectives, and remote atomic operations. In addition to operations for ULPs, it provides an out-of-band communication channel required typically required to wire-up communication libraries.

  14. Communication and development. Obstacles in implementing development programmes.

    PubMed

    Rodrigo, M L

    1989-01-01

    In developing countries communication is an important part of development, but will not generate development itself. In agricultural development in Third World countries 2 models are used: the innovation diffusion model and the package program model. These methods did not meet the needs of the small farmer, since they focused on single crop production. Most of these services do not spend time diagnosing the needs of individual farmers and give standard recommendations that do not suit many clients. Irrigation development projects require special communications skills, and in some cases in Mexico and Peru there were poor communications between farmers and the technical experts. Some argue that a strong state irrigation bureaucracy is needed to build and maintain a complex system, but others state farmer participation and cooperation as mandatory. In the health education area, the mass media is in question on its role as an educator. The confusion caused by advertising of Western medicine and miracle healings can be a major obstacle to health education. In family planning programs in these countries failures have been due to poor communication strategies that were built on false assumptions. The use of mass media including radio, television, and satellite has had some successes and failures in literacy programs. The communication factors that cause failures in these various programs are the lack of understanding and insight of the planners on the needs of their clients. Poorly developed messages, improper channels, and top down methods also cause these poor results. PMID:12282929

    Leroy, B. E.

    1982-01-01

    It was proposed that a satellite-based land mobile radio system could effectively extend the terrestrial cellular mobile system into rural and remote areas. The market, technical and economic feasibility for such a system is studied. Some of the aspects of implementing an operational mobile-satellite system are discussed. In particular, two key factors in implementation are examined: (1) bandwidth requirements; and (2) frequency sharing. Bandwidth requirements are derived based on the satellite antenna requirements, modulation characteristics and numbers of subscribers. Design trade-offs for the satellite system and potential implementation scenarios are identified. Frequency sharing is examined from a power flux density and modulation viewpoint.

    2013-05-01

    This article discusses a danger alert system created as a part of the research project at Department of Telecommunications of Technical University of Ostrava. The aim of the system is to distribute pre-recorded voice messages in order to alert the called party in danger. This article describes individual technologies, which the application uses for its operation as well as issues relating to hardware requirements and transfer line bandwidth load. The article also describes new algorithms, which had to be developed in order to ensure the reliability of the system. Our intent is focused on disaster management, the message, which should be delivered within specified time span, is typed in the application and text-to-speech module ensures its transformation to a speech format, after that a particular scenario or warned area is selected and a target group is automatically unloaded. For this purpose, we have defined XML format for delivery of phone numbers which are located in the target area and these numbers are obtained from mobile BTS's (Base transmission stations). The benefit of such communication compared to others, is the fact, that it uses a phone call and, therefore, it is possible to get feedback who accepted the message and to improve efficiency of alert system. Finally, the list of unanswered calls is exported and these users can be informed via SMS.

  12. Causality and Communication: Relativistic astrophysical jets and the implementation of science communication training in astronomy classes

    NASA Astrophysics Data System (ADS)

    Kohler, Susanna

    Part I: Relativistic jets emitted from the centers of some galaxies (called active galaxies) exhibit many interesting behaviors that are not yet fully understood: acceleration and collimation over vast distances, for instance, and occasional flaring activity. In the first part of my thesis, I examine the possibility of collimation and acceleration of relativistic jets by the pressure of the ambient medium surrounding the jet base. I discuss the differences in predicted jet behavior due to including the effects of a magnetic field threading the jet interior, and I describe the conditions that create some observed jet shapes, such as the "hollow cone" structure seen in M87 and similar jets. I also discuss what happens when the pressure outside of the jet drops so slowly that the jet shocks repeatedly, generating entropy at its boundary. Finally, I examine the spectra of the 40 brightest gamma-ray flares from blazars (active galaxies with jets pointed toward us) recorded by the Fermi Gamma-ray Space Telescope in its first four years of operation. I develop models to describe the observed behavior of these flares and discuss the physical implications of these models. Part II: The ability to clearly communicate scientific concepts to both peers and the lay public is an important component of being a scientist. Few training programs exist, however, for scientists to obtain these skills. In the second part of my thesis, I examine the impact of two different training efforts for very early-career scientists: first, a short science communication workshop for science, technology, engineering and math (STEM) graduate students, and second, science communication training integrated into existing astronomy classes for undergraduate STEM majors and early STEM graduate students. I evaluate whether the students' written communication skills demonstrate measurable improvement after training, and track students' attitudes toward science communication.

    Welch, Donald A; Shamis, Pavel; Gorentla Venkata, Manjunath; Poole, Stephen W; Tony, Curtis

    2014-01-01

    OpenSHMEM is an effort to standardize the well-known SHMEM parallel programming library. The project aims to produce an open-source and portable SHMEM API and is led by ORNL and UH. In this paper, we optimize the current OpenSHMEM reference implementa- tion, based on GASNet, to achieve higher performance characteristics. To achieve these desired performance characteristics, we have redesigned an important component of the OpenSHMEM implementation, the network layer, to leverage a low-level communication library designed for imple- menting parallel programming models called UCCS. In particular, UCCS provides an interface and semantics such as native atomic operations and remote memory operations to better support PGAS programming models, including OpenSHMEM. Through the use of microbenchmarks, we evaluate this new OpenSHMEM implementation on various network metrics, including the latency of point-to-point and collective operations. Furthermore, we compare the performance of our OpenSHMEM imple- mentation with the state-of-the-art SGI SHMEM. Our results show that the atomic operations of our OpenSHMEM implementation outperform SGI s SHMEM implementation by 3%. Its RMA operations outperform both SGI s SHMEM and the original OpenSHMEM reference implemen- tation by as much as 18% and 12% for gets, and as much as 83% and 53% for puts.

  1. Optimizing local protocols for implementing bipartite nonlocal unitary gates using prior entanglement and classical communication

    SciTech Connect

    Cohen, Scott M.

    2010-06-15

    We present a method of optimizing recently designed protocols for implementing an arbitrary nonlocal unitary gate acting on a bipartite system. These protocols use only local operations and classical communication with the assistance of entanglement, and they are deterministic while also being 'one-shot', in that they use only one copy of an entangled resource state. The optimization minimizes the amount of entanglement needed, and also the amount of classical communication, and it is often the case that less of each of these resources is needed than with an alternative protocol using two-way teleportation.

  3. Prototype development and implementation of picture archiving and communications systems based on ISO-OSI standard

    NASA Astrophysics Data System (ADS)

    Martinez, Ralph; Nam, Jiseung

    1992-07-01

    Picture Archiving and Communication Systems (PACS) is an integration of digital image formation in a hospital, which encompasses various imaging equipment, image viewing workstations, image databases, and a high speed network. The integration requires a standardization of communication protocols to connect devices from different vendors. The American College of Radiology and the National Electrical Manufacturers Association (ACR- NEMA) standard Version 2.0 provides a point-to-point hardware interface, a set of software commands, and a consistent set of data formats for PACS. But, it is inadequate for PACS networking environments, because of its point-to-point nature and its inflexibility to allow other services and protocols in the future. Based on previous experience of PACS developments in The University of Arizona, a new communication protocol for PACS networks and an approach were proposed to ACR-NEMA Working Group VI. The defined PACS protocol is intended to facilitate the development of PACS''s capable of interfacing with other hospital information systems. Also, it is intended to allow the creation of diagnostic information data bases which can be interrogated by a variety of distributed devices. A particularly important goal is to support communications in a multivendor environment. The new protocol specifications are defined primarily as a combination of the International Organization for Standardization/Open Systems Interconnection (ISO/OSI), TCP/IP protocols, and the data format portion of ACR-NEMA standard. This paper addresses the specification and implementation of the ISO-based protocol into a PACS prototype. The protocol specification, which covers Presentation, Session, Transport, and Network layers, is summarized briefly. The protocol implementation is discussed based on our implementation efforts in the UNIX Operating System Environment. At the same time, results of performance comparison between the ISO and TCP/IP implementations are presented

    It is predicted that the number of internet-of-things (IoT) devices will be >28 billion in 2020. Due to the shortage of the conventional radio-frequency spectrum, using visible light communication (VLC) for IoT can be promising. IoT networks may only require very low-data rate communication for transmitting sensing or identity information. The implementation of a VLC link on existing computer communication standards and interfaces is important. Among the standards, universal asynchronous receiver/transmitter (UART) is very popular. We propose and demonstrate a VLC-over-UART system. Bit error rate analysis is performed. Different components and modules used in the proposed VLC-over-UART system are discussed. Then, we also demonstrate a real-time simultaneous temperature, humidity, and illuminance monitoring using the proposed VLC link.

  5. Primer on the Implementation of a Pharmacy Intranet Site to Improve Department Communication

    Hale, Holly J.

    2013-01-01

    Purpose: The purpose of the article is to describe the experience of selecting, developing, and implementing a pharmacy department intranet site with commentary regarding application to other institutions. Clinical practitioners and supporting staff need an effective, efficient, organized, and user-friendly communication tool to utilize and relay information required to optimize patient care. Summary: To create a functional and user-friendly department intranet site, department leadership and staff should be involved in the process from selection of product through implementation. A product that supports both document storage management and communication delivery and has the capability to be customized to provide varied levels of site access is desirable. The designation of an intranet site owner/developer within the department will facilitate purposeful site design and site maintenance execution. A well-designed and up-to-date site along with formal end-user training are essential for staff adoption and continued utilization. Conclusion: Development of a department intranet site requires a considerable time investment by several members of the department. The implementation of an intranet site can be an important step toward achieving improved communications. Staff utilization of this resource is key to its success. PMID:24421523

    2012-02-01

    The availability of the Picture Archiving and Communication System (PACS) has revolutionized the practice of radiology in the past two decades and has shown to eventually increase productivity in radiology and medicine. PACS implementation and integration may bring along numerous unexpected issues, particularly in a large-scale enterprise. To achieve a successful PACS implementation, identifying the critical success and failure factors is essential. This article provides an overview of the process of implementing and integrating PACS in a comprehensive health system comprising an academic core hospital and numerous community hospitals. Important issues are addressed, touching all stages from planning to operation and training. The impact of an enterprise-wide radiology information system and PACS at the academic medical center (four specialty hospitals), in six additional community hospitals, and in all associated outpatient clinics as well as the implications on the productivity and efficiency of the entire enterprise are presented.

  13. Implementing MPI-IO atomic mode and shared file pointers using MPI one-sided communication.

    The ROMIO implementation of the MPI-IO standard provides a portable infrastructure for use on top of a variety of underlying storage targets. These targets vary widely in their capabilities, and in some cases additional effort is needed within ROMIO to support all MPI-IO semantics. Two aspects of the interface that can be problematic to implement are MPI-IO atomic mode and the shared file pointer access routines. Atomic mode requires enforcing strict consistency semantics, and shared file pointer routines require communication and coordination in order to atomically update a shared resource. For some file systems, native locks may be used to implement these features, but not all file systems have lock support. In this work, we describe algorithms for implementing efficient mutex locks using MPI-1 and the one-sided capabilities from MPI-2. We then show how these algorithms may be used to implement both MPI-IO atomic mode and shared file pointer methods for ROMIO without requiring any features from the underlying file system. We show that these algorithms can outperform traditional file system lock approaches. Because of the portable nature of these algorithms, they are likely useful in a variety of situations where distributed locking or coordination is needed in the MPI-2 environment.

    Four distinct packet communication requirements for network architectured computer systems are: system control, dataflow data type movement, SIMD, data realignment and movement of high volume data between MIMD configurations when memory sharing is unavailable or too costly. This paper defines and describes a packet switching mechanism which meets each of these requirements. Mechanisms are also defined and described for breaking and restoring SIMD execution structures which are required to complete the implementation of packet switching for SIMD execution. The mechanisms were defined and are described in the context of the Texas reconfigurable array computer (TRAC), but should be in large measure adaptable to other network architectured systems. 8 references.

    When a student has some questions on a class subject, he should ask questions in his class. However, the student, who cannot ask the question in the class, has to go to the teacher to ask questions after hours. In such a case, it is the problem that profitable information discussed between the teacher and the student by questioning will not spread over all students. Therefore, we have designed and implemented the system which provides smooth communication and sharing information after hours. In this paper, we describes the further improvement on enriched expressions and the usability on Web.

    Cathode Anode Satellite Thruster for Orbital Reposition (CASTOR) is an orbital manoeuvre and transfer micro-satellite bus developed at MIT Space System Laboratory. The technical objective of the mission is achieving 1 km/s of delta-V over a 1 year mission in Low Earth Orbit (LEO). This will be accomplished using a novel electric propulsion system, the Diverging Cusped Field Thruster (DCFT), which enables high efficiency orbital changes of the ESPA-ring class satellite. CASTOR is capable of improving rapid access to space capabilities by providing an orbital transfer platform with a very high performance to mass ratio, thus greatly reducing launch costs and allowing for highly efficient orbital manoeuvre. Furthermore, CASTOR is highly scalable and modular, allowing it to be adapted to a wide range of scales and applications. CASTOR is developed as part of the University Nanosatellite Program (UNP) funded by Air Force Research Laboratory (AFRL). In order to accomplish CASTOR mission objective, a highly optimized, scalable, light weight, and low cost communication system needed to be developed. These constraints imply the development of trade studies to select the final communication system architecture able to maximize the amount of data transmitted, while guaranteeing reliability, redundancy and limited mass, power consumption, and cost. A special attention is also required to guarantee a reliable communication system in cases of tumbling, or in case of strong Doppler shift which is inevitable due to the high delta-V capabilities of the vehicle. In order to accomplish all the mission requirements, different features have been introduced in the design of the communication system for this mission. Specifically, customized patch antennas have been realized, and a customized communication protocol has been designed and implemented. The communication subsystem has been validated through an intense testing campaign which included software tests in the laboratory, hardware

    Two large X-ray departments in the County of Stockholm have changed from traditional analogue technology to digital imaging, including the implementation of Picture Archiving and Communication Systems (PACS). One of the departments was moved to a completely new purpose-built building and equipped with the latest technology, but for the other one the change merely meant rebuilding and adaptation of existing rooms on the premises. The objectives of the present study were to evaluate the ergonomics effects of the new technique in the two X-ray departments and to find out whether the implementation of digital imaging technique came up to expectations of improved ergonomics and work environment. Another purpose was to compare the outcomes for the two departments, in order to learn about the importance of the different implementation approaches. Questionnaires were sent out to the two departments both before the implementation of PACS and after the transition. The questionnaires covered several aspects of work conditions, such as working time, the physical and psychosocial environment, physical work load and musculoskeletal complaints, expectations from the digital technology, etc. The changeover went better than expected and even high expectations were fulfilled and surpassed. However, there were also some unexpected and distressing results; for example, a substantial increase in headaches and musculoskeletal symptoms as well as the use of pain killers among the radiologists of one of the X-ray departments.

    This thesis work is to implement the receiver pan of the SNR high speed network transport protocol. The approach was to use the Systems of Communicating Machines (SCM) as the formal definition of the protocol. Programs were developed on top of the Unix system using C programming language. The Unix system features that were adopted for this implementation were multitasking, signals, shared memory, semaphores, sockets, timers and process control. The problems encountered, and solved, were signal loss, shared memory conflicts, process synchronization, scheduling, data alignment and errors in the SCM specification itself. The result was a correctly functioning program which implemented the SNR protocol. The system was tested using different connection modes, lost packets, duplicate packets and large data transfers. The contributions of this thesis are: (1) implementation of the receiver part of the SNR high speed transport protocol; (2) testing and integration with the transmitter part of the SNR transport protocol on an FDDI data link layered network; (3) demonstration of the functions of the SNR transport protocol such as connection management, sequenced delivery, flow control and error recovery using selective repeat methods of retransmission; and (4) modifications to the SNR transport protocol specification such as corrections for incorrect predicate conditions, defining of additional packet types formats, solutions for signal lost and processes contention problems etc.

    The development and implementation of worksite health and wellness programs (WHWPs) in the United States (US) hold promise as a means to improve population health and reverse current trends in non-communicable disease incidence and prevalence. However, WHWPs face organizational, economic, systematic, legal, and logistical challenges which have combined to impact program availability and expansion. Even so, there is a burgeoning body of evidence indicating WHWPs can significantly improve the health profile of participating employees in a cost effective manner. This foundation of scientific knowledge justifies further research inquiry to elucidate optimal WHWP models. It is clear that the development, implementation and operation of WHWPs require a strong commitment from organizational leadership, a pervasive culture of health and availability of necessary resources and infrastructure. Since organizations vary significantly, there is a need to have flexibility in creating a customized, effective health and wellness program. Furthermore, several key legal issues must be addressed to facilitate employer and employee needs and responsibilities; the US Affordable Care Act will play a major role moving forward. The purposes of this review are to: 1) examine currently available health and wellness program models and considerations for the future; 2) highlight key legal issues associated with WHWP development and implementation; and 3) identify challenges and solutions for the development and implementation of as well as adherence to WHWPs.

    The collection of environmental samples presents a responsibility to return information to the affected participants. Explaining complex and often ambiguous scientific information to a lay audience is a challenge. As shown by environmental justice research, this audience frequently has limited formal education, increasing the challenge for researchers to explain the data collected, the risk indicated by the findings, and action the affected community should take. In this study we describe the development and implementation of a risk communication strategy for environmental pesticide samples collected in the homes of Latino/a migrant and seasonal farmworkers in a community-based participatory research project. The communication strategy was developed with community input and was based on face-to-face meetings with members of participating households. Using visual displays of data effectively conveyed information about individual household contamination and placed it in the context of community findings. The lack of national reference data and definitive standards for action necessitated a simplified risk message. We review the strengths and weaknesses of such an approach and suggest areas for future research in risk communication to communities affected by environmental health risks. PMID:15064174

    At the Faculty of Medicine in Heidelberg, implementation of an interdisciplinary longitudinal curriculum was started in 2001 with the goal of achieving sustained promotion of communicative and clinical competences. The aim of this paper is to describe the development and implementation of Heidelberg's longitudinal communication curriculum. Furthermore, innovative aspects and strategies are discussed. The methodological approaches for development and implementation were Kern's "Six-step Approach" and a SWOT analysis. The process resulted in an innovative communication curriculum that starts with an integrated curriculum for developing clinical and communicative competence in the pre-clinical phase and continues in the clinical phase with medical communication and interactive training. Satisfaction with the communication curriculum and its effectiveness were rated highly by students. Residents who had graduated from Faculty of Medicine in Heidelberg rated the extent to which they had communicative competencies at the time of their graduation at their disposal significantly higher than residents who had graduated from the other 4 medical faculties in Baden-Württemberg. The experiences gained in Heidelberg can be applied by other faculties. PMID:25941988

    Quantum repeaters provide a way for long distance quantum communication through optical fiber networks. Transmission losses and operation errors are two major challenges to the implementation of quantum repeaters. At each intermediate repeater station, transmission losses can be overcome using either heralded entanglement generation or quantum error correction, while operation errors can be corrected via entanglement purification or quantum error correction. Depending on the mechanisms used to correct loss and operation errors respectively, three generations of quantum repeaters have been proposed. We present a quantitative comparison of different quantum repeater schemes by evaluating the time- and qubit-resource consumed simultaneously. We can identify the most efficient scheme for given technological capabilities, which are characterized by fiber coupling efficiency, local gate fidelity, and local gate speed. Our work provides a roadmap for high-speed quantum networks across continental distances. Linshu and Sreraman contributed equally to this work.

    1988-01-01

    The methods for viewing and managing radiological images have remained relatively unchanged for several decades. Inefficiencies in the current system result in mismanaged films and delays in medical reporting. This study presents the design, implementation and evaluation of a novel picture archiving and communication system (PACS) within the pediatric radiology section of a 500-bed teaching hospital. The system is composed of an integrated network of computerized devices used to digitally acquire, store, manage, display, and process radiological images. The key PACS issues covered in this dissertation include: (a) definition of data, processing, and user requirements, (b) software and hardware integration of various radiological imaging subsystems, (c) design of an efficient database structure which manages several thousand megabytes of information, (d) system performance tuning, (e) development of an acceptable user interface to a six-monitor 512 {times} 512 line CRT workstation, and (f) clinical evaluation.

    Blind channel estimation is critical for digital signal processing (DSP) compensation of optical fiber communications links. The overall channel consists of deterministic distortions such as chromatic dispersion, as well as random and time varying distortions including polarization mode dispersion and timing jitter. It is critical to obtain robust acquisition and tracking methods for estimating these distortions effects, which, in turn, can be compensated by means of DSP such as Maximum Likelihood Sequence Estimation (MLSE). Here, a novel blind estimation algorithm is developed, accompanied by inclusive mathematical modeling, and followed by extensive set of real time experiments that verify quantitatively its performance and convergence. The developed blind channel estimation is used as the basis of an MLSE receiver. The entire scheme is fully implemented in a 65 nm CMOS Application Specific Integrated Circuit (ASIC). Experimental measurements and results are presented, including Bit Error Rate (BER) measurements, which demonstrate the successful data recovery by the MLSE ASIC under various channel conditions and distances.

  10. Lessons Learned from Implementation of Information and Communication Technologies in Spain's Healthcare Services

    Carnicero, J.; Rojas, D.

    2010-01-01

    Background Spain’s health services have undertaken a number of important projects aimed at the creation of Electronic Health Records (EHR) through the incorporation of Information and Communication Technologies (ICT) into patient care practices. The objective of this endeavor is to improve care quality and efficiency and increase responsiveness to the population's needs and demands. Between 2006-2009 over 300 million Euro were invested in projects of this type. Objective To better understand the success criteria, the difficulties encountered and certain issues that must be kept in mind to ensure successful implementation of ICT projects in health organizations, based on Spain's experiences in this field. Methods The projects' results are analyzed using the criteria of compliance with the expected scope, cost and time frame. Results The results can be considered satisfactory in primary care facilities, where almost 90% of Spain's general practitioners, pediatricians and primary care nurses are using electronic health record (EHR) systems. In hospitals EHR implementation is more uneven. Over 40% of Spanish primary care centers and 42% of pharmacies are using electronic prescription (the information system that connects the physician to the dispensing pharmacy and the dispensing pharmacy to the payer). Discussion All of Spain’s health services are currently carrying out projects involving ICT application in healthcare, and a priori the benefits of ICT are not questioned. However, the costs and time frames required for these projects are clearly surpassing initial expectations, while the benefits perceived by both professionals and institutions remain limited. This situation may be due in part to the absence of a project management culture in the health services, which has led them to pay insufficient attention to the main difficulties and key issues related to the implementation of EHR.

    This paper reports on the design considerations and implementations of construction of a receiver system for an infrared communication link using Light-Emitting-Diodes (LEDs). System configuration is non-directed line of sight (LOS) with single element receiver. The speed of the system constructed is 20 MHz (40 Mbps for on-off keying). In our design, the receiver consists of a multi-channel photo-detector array followed by multi-channels transimpedance amplifiers, a summer circuit for combining signals, low-pass filters(LPF) and high pass filters(HPF), and auto-gain control unit(AGC). The spectral match between photodiode and LED, looking angle of photodiode, rise time consideration of the photodiode, trade-off between transit rise time and photodiode effective area, etc, are also be discussed . A receiver module of speed response up to 20 MHz has been successfully constructed and the system is capable of receiving optical signal at a height of 2 m from the ceiling with coverage of a cell of 4 m in diameter.

    In this paper, a new stereoscopic 3D imaging communication system for real-time teleconferencing application is implemented by using IEEE 1394 digital cameras, Intel Xeon server computer system and Microsoft"s DirectShow programming library and its performance is analyzed in terms of image-grabbing frame rate. In the proposed system, two-view images are captured by using two digital cameras and processed in the Intel Xeon server computer system. And then, disparity data is extracted from them and transmitted to the client system with the left image through an information network and in the recipient two-view images are reconstructed and displayed on the stereoscopic 3D display system. The program for controlling the overall system is developed using the Microsoft DirectShow SDK. From some experimental results, it is found that the proposed system can display stereoscopic images in real-time with a full-color of 16 bits and a frame rate of 15fps.

    The design and implementation of hardware and software systems involved in using a 40,000 bit/second communication line as the connecting link between an IMLAC PDS 1-D display computer and a Univac 1108 computer system were described. The IMLAC consists of two independent processors sharing a common memory. The display processor generates the deflection and beam control currents as it interprets a program contained in the memory; the minicomputer has a general instruction set and is responsible for starting and stopping the display processor and for communicating with the outside world through the keyboard, teletype, light pen, and communication line. The processing time associated with each data byte was minimized by designing the input and output processes as finite state machines which automatically sequence from each state to the next. Several tests of the communication link and the IMLAC software were made using a special low capacity computer grade cable between the IMLAC and the Univac.

    Communication in its many forms is a critical component for an effective Space Grant Program. Good communication is needed within individual Space Grant College/Consortia, for example between consortium affiliates and the consortium program office. Effective communication between the several programs, NASA Headquarters, and NASA field centers also is required. Further, communication among the above program elements, industry, local and state government, and the public also are necessary for meeting program objectives.

    2014-12-04

    We investigate distributed implementation of two-qubit unitary operations over two primitive networks, the butterfly network and the ladder network, as a first step to apply network coding for quantum computation. By classifying two-qubit unitary operations in terms of the Kraus-Cirac number, the number of non-zero parameters describing the global part of two-qubit unitary operations, we analyze which class of two-qubit unitary operations is implementable over these networks with free classical communication. For the butterfly network, we show that two classes of two-qubit unitary operations, which contain all Clifford, controlled-unitary and matchgate operations, are implementable over the network. For the ladder network, we show that two-qubit unitary operations are implementable over the network if and only if their Kraus-Cirac number do not exceed the number of the bridges of the ladder.

    Novel space mission concepts such as Federated Satellite Systems promise to enhance sustainability, robustness, and reliability of current missions by means of in-orbit sharing of space assets. This new paradigm requires the utilization of several technologies in order to confer flexibility and re-configurability to communications systems among heterogeneous spacecrafts. This paper illustrates the results of the experimental demonstration of the value proposition of federated satellites through two stratospheric balloons interoperating with a tracking ground station through Commercial Off-The-Shelf Software Defined Radios (SDRs). The paper reports telemetry analysis and characterizes the communications network that was realized in-flight. Furthermore, it provides details on an in-flight anomaly experienced by one of the balloons, which was recovered through the use of the federated technology that has been developed. The anomaly experienced led to the early loss of the directional link from the ground station to the affected stratospheric balloon node after 15 min in flight. Nevertheless, thanks to the federated approach among the systems, the ground station was still able to retrieve the balloon's data in real time through the network system, for which the other balloon operated as a federated relay for 45 min in flight, uninterrupted. In other words, the federated approach to the system allowed triplicating the useful lifetime of the defective system, which would have not been possible to realize otherwise. Such anomaly coincidentally demonstrated the value of the federated approach to space systems design. The paper paves the way for future tests on space assets.

    Last year, the Simulation Interoperability Standards Organization (SISO) inaugurated the now annual High Level Architecture (HLA) Smackdown at the Spring Simulation Interoperability Workshop (SIW). A primary objective of the Smackdown event is to provide college students with hands-on experience in the High Level Architecture (HLA). The University of Alabama in Huntsville (UAHuntsville) fielded teams in 2011 and 2012. Both the 2011 and 2012 smackdown scenarios were a lunar resupply mission. The 2012 UAHuntsville fielded four federates: a communications network Federate called Lunar Communications and Navigation Satellite Service (LCANServ) for sending and receiving messages, a Lunar Satellite Constellation (LCANSat) to put in place radios needed by the communications network for Line-Of-Sight communication calculations, and 3D graphical displays of the orbiting satellites and a 3D visualization of the lunar surface activities. This paper concentrates on the first two federates by describing the functions, algorithms, the modular FOM, experiences, lessons learned and recommendations for future Smackdown events.

    Various aspects of the shuttle orbiter S-band network communication system, the S-band payload communication system, and the Ku-band communication system are considered. A method is proposed for obtaining more accurate S-band antenna patterns of the actual shuttle orbiter vehicle during flight because the preliminary antenna patterns using mock-ups are not realistic that they do not include the effects of additional appendages such as wings and tail structures. The Ku-band communication system is discussed especially the TDRS antenna pointing accuracy with respect to the orbiter and the modifications required and resulting performance characteristics of the convolutionally encoded high data rate return link to maintain bit synchronizer lock on the ground. The TDRS user constraints on data bit clock jitter and data asymmetry on unbalanced QPSK with noisy phase references are included. The S-band payload communication system study is outlined including the advantages and experimental results of a peak regulator design built and evaluated by Axiomatrix for the bent-pipe link versus the existing RMS-type regulator. The nominal sweep rate for the deep-space transponder of 250 Hz/s, and effects of phase noise on the performance of a communication system are analyzed.

    Objective: With this article we want to support teachers and curriculum planners to be aware of and apply knowledge and recommendations of organisational (OD), curriculums (CD) and human resource development (HRD) ideas already in the planning phase of a project. Taking these into account can influence the process of change successfully and controlled during the introduction and establishment of curricula in the field of communication and social skills in medical education. Approach and Results: In the context of a multi-stage developmental process, a recommendation on CD for "Communicative and social competencies" was developed. The basis for it was made during two workshops of the GMA-committee "Communicative and social competencies" and supplemented by the available literature and the experience of communication experts. The "Undeloher Recommendation" (see attachment ) includes a compilation of recommendations and guiding questions, which is geared to the various phases of CD. Additionally, general approaches and recommendations of organisational and human resource development were integrated, which turned out to be particularly relevant in the process of CD. Thus, the "Undeloher recommendation" includes an orientation for each phase of the curriculum development process, the organisation and the staff in order to successfully implement a longitudinal curriculum. In addition to theoretical models the long-term discussion process and the personal experiences of a variety of curriculum planners and teachers have been integrated. Conclusion: The "Undeloher recommendation" can support the implementation processes of curricula in communication and social skills during development and realisation. Its application was reviewed in the context of workshops based on concrete examples. The participating teachers and curriculum planners assessed it to be very helpful. The recommendation goes beyond of what has been described in terms of content models in the CD so fare. In

    In recent years, robots have started to become more commonplace in our lives, from factory floors to museums, festivals and shows. They have started to change how we work and play. With an increase in the population of the elderly, they have also been started to be used for caregiving services, and hence many countries have been investing in the robot development. The advancements in robotics and wireless communications has led to the emergence of autonomous caregiving robot teams which cooperate to accomplish a set of tasks assigned by human operators. Although wireless communications and devices are flexible and convenient, they are vulnerable to many risks compared to traditional wired networks. Since robots with wireless communication capability transmit all data types, including sensory, coordination, and control, through radio frequencies, they are open to intruders and attackers unless protected and their openness may lead to many security issues such as data theft, passive listening, and service interruption. In this paper, a secure web-based communication framework is proposed to address potential security threats due to wireless communication in robot-robot and human-robot interaction. The proposed framework is simple and practical, and can be used by caregiving robot teams in the exchange of sensory data as well as coordination and control data.

Monitoring software is developed using VB6.0 for data input/output, flow control and online parameters setting. As a result, all functions are fulfilled with robust performance. It is concluded from results that one PC can monitor several PLCs using RS-485 communication.

  3. Using the Theory of Planned Behaviour and implementation intentions to predict and facilitate upward family communication about mammography.

    Regular mammography facilitates early detection of breast cancer, and thus increases the chances of survival from this disease. Daughter-initiated (i.e. upward) communication about mammography within mother-daughter dyads may promote mammography to women of screening age. The current study examined this communication behaviour within the context of the Theory of Planned Behaviour (TPB), and aimed to bridge the intention-behaviour gap by trialling an implementation intention (II) intervention that aimed to facilitate upward family communication about mammography. Young women aged 18-39 (N=116) were assigned to either a control or experimental condition, and the latter group formed IIs about initiating a conversation with an older female family member about mammography. Overall, those who formed IIs were more likely to engage in the target communication behaviour, however the intervention was most effective for those who reported low levels of intention at baseline. Perceived behavioural control emerged as the most important variable in predicting the target behaviour. The altruistic nature of this behaviour, and the fact that it is not wholly under volitional control, may have contributed to this finding. Future studies that systematically explore the relative roles of intention and perceived behavioural control in behaviours of this nature are warranted. PMID:21981385

    1995-12-31

    The Contaminant Analysis Automation (CAA) project defines the automated laboratory as a series of standard laboratory modules (SLM) serviced by a robotic standard support module (SSM). These SLMs are designed to allow plug-and-play integration into automated systems that perform standard analysis methods (SAM). While the SLMs are autonomous in the execution of their particular chemical processing task, the SAM concept relies on a high-level task sequence controller (TSC) to coordinate the robotic delivery of materials requisite for SLM operations, initiate an SLM operation with the chemical method dependent operating parameters, and coordinate the robotic removal of materials from the SLM when its commands and events has been established to allow ready them for transport operations as well as performing the Supervisor and Subsystems (GENISAS) software governs events from the SLMs and robot. The Intelligent System Operating Environment (ISOE) enables the inter-process communications used by GENISAS. CAA selected the Hewlett-Packard Optimized Robot for Chemical Analysis (ORCA) and its associated Windows based Methods Development Software (MDS) as the robot SSM. The MDS software is used to teach the robot each SLM position and required material port motions. To allow the TSC to command these SLM motions, a hardware and software implementation was required that allowed message passing between different operating systems. This implementation involved the use of a Virtual Memory Extended (VME) rack with a Force CPU-30 computer running VxWorks; a real-time multitasking operating system, and a Radiuses PC compatible VME computer running MDS. A GENISAS server on The Force computer accepts a transport command from the TSC, a GENISAS supervisor, over Ethernet and notifies software on the RadiSys PC of the pending command through VMEbus shared memory. The command is then delivered to the MDS robot control software using a Windows Dynamic Data Exchange conversation.

    2002-02-28

    Argentina will require new sites for the location of radioactive waste final disposal systems. It is currently mandatory to have social and political consensus to obtain the corresponding agreements. The experience obtained with the cancellation of the project ''Feasibility Study and Engineering Project--Repository for High Level Radioactive Waste'', reinforces even more the necessity to count with the acceptance of the public to carry out projects of this kind. The first phase of the former was developed in the 80's: geological, geophysical and hydrogeological studies were performed in a compact granitic rock located in Sierra del Medio, Chubut province. This project had to be called off in the early 90's due to strong social rejection. This decision was closely related to the poor attention given to social communication issues. The governmental decision-makers in charge underwent a lot of pressure from social groups claiming for the cancellation of the project due to the lack of information and the fear it triggered. Thus, the lesson learnt: ''social communication activities must be carefully undertaken in order to achieve the appropriate management of the radioactive waste produced in our country.'' The same as in other countries, the specific National Law demands the formulation of a Strategic Plan which will not only include the research into radioactive waste, but the design of a Social Communication Programme as well. The latter will be in charge of informing the population clearly and objectively about the latest scientific and technological advances in the issue. A tentative perception-attitude pattern of the Argentine society about the overall nuclear issue is outlined in this paper. It is meant to contribute to the understanding of the public's adverse reaction to this kind of project. A communication programme is also presented. Its objective is to install the waste management topic in the public's opinion with a positive real outlook.

    We examine the mechanics of the send and receive mechanism of MPI and in particular how we can implement message passing in a robust way so that our performance is not significantly affected by changes to the MPI system. This leads us to using the Isend/Irecv protocol which will entail sometimes significant algorithmic changes. We discuss this within the context of two different algorithms for sparse Gaussian elimination that we have parallelized. One is a multifrontal solver called MUMPS, the other is a supernodal solver called SuperLU. Both algorithms are difficult to parallelize on distributed memory machines. Our initial strategies were based on simple MPI point-to-point communication primitives. With such approaches, the parallel performance of both codes are very sensitive to the MPI implementation, the way MPI internal buffers are used in particular. We then modified our codes to use more sophisticated nonblocking versions of MPI communication. This significantly improved the performance robustness (independent of the MPI buffering mechanism) and scalability, but at the cost of increased code complexity.

    2014-01-01

    Context: Implementing the Affordable Care Act (ACA) in 2014 will require effective enrollment and outreach efforts to previously uninsured individuals now eligible for coverage. Methods: From 1996 to 2013, the Health Communication Research Laboratory conducted more than 40 original studies with more than 30,000 participants to learn how to improve the reach to and effectiveness of health information for low-income and racial/ethnic minority populations. We synthesized the findings from this body of research and used them to inform current challenges in implementing the ACA. Findings: We found empirical support for 5 recommendations regarding partnerships, outreach, messages and messengers, life priorities of low-income individuals and families, and the information environment. We translated these into 12 action steps. Conclusions: Health communication science can inform the development and execution of strategies to increase the public's understanding of the ACA and to support the enrollment of eligible individuals into Medicaid or the Health Insurance Marketplace.

    Truncated Fourier, Gauss, Kummer and exponential sums can be used to factorize numbers: for a factor these sums equal unity in absolute value, whereas they nearly vanish for any other number. We show how this factorization algorithm can emerge from superpositions of classical light waves and we present a number of simple implementations in optics.

    2013-01-01

    This paper presents the synchronization between the master and slave Lorenz chaotic systems by slide mode controller (SMC)-based technique. A proportional-integral (PI) switching surface is proposed to simplify the task of assigning the performance of the closed-loop error system in sliding mode. Then, extending the concept of equivalent control and using some basic electronic components, a secure communication system is constructed. Experimental results show the feasibility of synchronizing two Lorenz circuits via the proposed SMC.  PMID:23429512

    Yu Li; Griffiths, Robert B.; Cohen, Scott M.

    2010-06-15

    Any bipartite nonlocal unitary operation can be carried out by teleporting a quantum state from one party to the other, performing the unitary gate locally, and teleporting a state back again. This paper investigates unitaries which can be carried out using less prior entanglement and classical communication than are needed for teleportation. Large families of such unitaries are constructed using (projective) representations of finite groups. Among the tools employed are: a diagrammatic approach for representing entangled states, a theorem on the necessary absence of information at certain times and locations, and a representation of bipartite unitaries based on a group Fourier transform.

    This paper describes an approach for relay of data-modulated subcarriers from Shuttle payloads through the Shuttle Ku-band communications subsystem (and subsequently through a tracking and data relay satellite system to a ground terminal). The novelty is that a channel originally provided for baseband digital data is shown to be suitable for this purpose; the resulting transmission scheme is referred to as a narrowband bent-pipe scheme. Test results demonstrating the validity of the narrowband bent-pipe mode are presented, and limitations on system performance are described.

  8. AMI Communication Requirements to Implement Demand-Response: Applicability of Hybrid Spread Spectrum Wireless

    SciTech Connect

    Hadley, Mark D.; Clements, Samuel L.; Carroll, Thomas E.

    2011-09-30

    While holistically defining the smart grid is a challenge, one area of interest is demand-response. In 2009, the Department of Energy announced over $4 billion in grant and project funding for the Smart Grid. A significant amount of this funding was allotted to utilities for cost sharing projects to deploy Smart Grid technologies, many of whom have deployed and are deploying advanced metering infrastructure (AMI). AMI is an enabler to increase the efficiency of utilities and the bulk power grid. The bulk electrical system is unique in that it produces electricity as it is consumed. Most other industries have a delay between generation and consumption. This aspect of the power grid means that there must be enough generation capacity to meet the highest demand whereas other industries could over produce during off-peak times. This requires significant investment in generation capacity to cover the few days a year of peak consumption. Since bulk electrical storage doesn't yet exist at scale another way to curb the need for new peak period generation is through demand-response; that is to incentivize consumers (demand) to curtail (respond) electrical usage during peak periods. Of the various methods proposed for enabling demand-response, this paper will focus on the communication requirements for creating an energy market using transactional controls. More specifically, the paper will focus on the communication requirements needed to send the peak period notices and receive the response back from the consumers.

    PubMed

    Reiner, B; Siegel, E

    2000-05-01

    The acquisition of expensive equipment such as picture archiving and communication systems (PACS) becomes increasingly difficult as capital budgets become tighter. Traditional ownership financing options in the form of direct purchase or financing (loan) have several limitations including technology obsolescence, higher fixed pricing, limited options for equipment disposal, and the need to tie up valuable capital. Alternative financing options, in the form of conventional lease and risk sharing arrangements, offer several theoretical advantages including technology obsolescence protection in the form of built-in upgrades, preservation of borrowing power, multiple end-of-term options, and payment flexibility (which can be directly tied to realized productivity and operational efficiency gains). These options are discussed, with emphasis on the acquisition of PACS. PMID:10843249

    The Internet of Things is integrating information systems, places, users and billions of constrained devices into one global network. This network requires secure and private means of communications. The building blocks of the Internet of Things are devices manufactured by various producers and are designed to fulfil different needs. There would be no common hardware platform that could be applied in every scenario. In such a heterogeneous environment, there is a strong need for the optimization of interoperable security. We present optimized elliptic curve Cryptography algorithms that address the security issues in the heterogeneous IoT networks. We have combined cryptographic algorithms for the NXP/Jennic 5148- and MSP430-based IoT devices and used them to created novel key negotiation protocol. PMID:26343677

    Introduction: The importance of content validity in the instrument psychometric and its relevance with reliability, have made it an essential step in the instrument development. This article attempts to give an overview of the content validity process and to explain the complexity of this process by introducing an example. Methods: We carried out a methodological study conducted to examine the content validity of the patient-centered communication instrument through a two-step process (development and judgment). At the first step, domain determination, sampling (item generation) and instrument formation and at the second step, content validity ratio, content validity index and modified kappa statistic was performed. Suggestions of expert panel and item impact scores are used to examine the instrument face validity. Results: From a set of 188 items, content validity process identified seven dimensions includes trust building (eight items), informational support (seven items), emotional support (five items), problem solving (seven items), patient activation (10 items), intimacy/friendship (six items) and spirituality strengthening (14 items). Content validity study revealed that this instrument enjoys an appropriate level of content validity. The overall content validity index of the instrument using universal agreement approach was low; however, it can be advocated with respect to the high number of content experts that makes consensus difficult and high value of the S-CVI with the average approach, which was equal to 0.93. Conclusion: This article illustrates acceptable quantities indices for content validity a new instrument and outlines them during design and psychometrics of patient-centered communication measuring instrument.

    While the field of wireless communication has developed dramatically over the past several decades, there are several notable applications of wireless technologies which impose constraints on power-consumption and form-factor that are not compatible with commercial technologies such as 802.11a,b,g or Bluetooth. These applications include implantable devices and remote monitoring devices. Such devices are better suited to transponder technology which is more power-efficient and can sustain data rates acceptable for these applications. Using a well-defined set of functional needs and system restrictions, we have developed an ultra-compact and ultra-low-powered transponder which contains spread spectrum (SS) logic for wireless communications. The transponder chip was designed and built in the Jazz BiCMOS SiGe technology. The device is activated via a pure tone and emits a SS response which is modulated over the carrier with binary phase shift keying (BPSK). The SS signal is a Gold Code generated from two 9-bit m-sequence generators. One of the m-sequences is seeded with a fixed value while the other 9-bit register is pinned out and can be a fixed ID or a bus to transmit data from a microcontroller. The data is received and decoded by a standard PC with a high-speed acquisition board. In order to support multiple devices at various distances, asynchronous decoding is applied. When active, the device draws less than 35 mW of power (@ 3.0V). Assuming a duty cycle of less than 1%, the device can be powered for several days using a very small coin battery. The device has been tested in the laboratory; natural environment testing is underway.

  15. An experimental distributed microprocessor implementation with a shared memory communications and control medium

    1980-01-01

    The distributed processing concept is defined in terms of control primitives, variables, and structures and their use in performing a decomposed discrete Fourier transform (DET) application function. The design assumes interprocessor communications to be anonymous. In this scheme, all processors can access an entire common database by employing control primitives. Access to selected areas within the common database is random, enforced by a hardware lock, and determined by task and subtask pointers. This enables the number of processors to be varied in the configuration without any modifications to the control structure. Decompositional elements of the DFT application function in terms of tasks and subtasks are also described. The experimental hardware configuration consists of IMSAI 8080 chassis which are independent, 8 bit microcomputer units. These chassis are linked together to form a multiple processing system by means of a shared memory facility. This facility consists of hardware which provides a bus structure to enable up to six microcomputers to be interconnected. It provides polling and arbitration logic so that only one processor has access to shared memory at any one time.

    1997-01-01

    Attempting to incorporate new technology into an existing environment is often very difficult. The problems are lengthy to resolve, wrought with confusion and seldom turn out like anyone expected. This document represents an overview of one such attempt. It outlines the general areas of concern which could be affected by a transition, and potential problems that may be encountered as a result of the effort. Over the past several decades, many local, state and federal agencies are pressing for more efficient use of frequency spectrums. The urgency of this issue has grown due to the demands of several groups wanting access to these channels for commercial use. Pager systems, cellular telephones, radio systems for private businesses all demand more space. Public safety agencies are starting to fear their needs will diminish in importance as the available channel spectrums are consumed by commercial ventures. How to share these channels, purchase appropriate equipment to meet your needs, and stay within a reasonable budget are not easy tasks. Public safety agencies who rely on communication networks in the performance of their jobs also know why encryption is important. Protecting the rights of citizens as police exchange information over the air, maintaining the integrity of an investigation and officer safety are all concerns police must address each time they use a radio.

    2012-06-20

    A gimbal-free wide field-of-regard (FOR) optical receiver has been built in a laboratory setting for proof-of-concept testing. Multiple datasets are presented that examine the overall FOR of the system and the receiver's ability to track and collect a signal from a moving source. The design is not intended to compete with traditional free space optical communication systems, but rather offer an alternative design that minimizes the number and complexity of mechanical components required at the surface of a small mobile platform. The receiver is composed of a micro-lens array and hexagonal bundles of large core optical fibers that route the optical signal to remote detectors and electronics. Each fiber in the bundle collects power from a distinct solid angle of space and a piezo-electric transducer is used to translate the micro-lens array and optimize coupling into a given fiber core in the bundle. The micro-lens to fiber bundle design is scalable, modular, and can be replicated in an array to increase aperture size. PMID:22722273

    Objectives To implement a 360-degree resident evaluation instrument on the postanesthesia care unit (PACU) rotation and to determine the reliability, feasibility, and validity of this tool for assessing residents' professionalism and interpersonal and communication skills. Methods Thirteen areas of evaluation were selected to assess the professionalism and interpersonal and communication skills of residents during their PACU rotation. Each area was measured on a 9-point Likert scale (1, unsatisfactory performance, to 9, outstanding performance). Rating forms were distributed to raters after the completion of the PACU rotation. Raters included PACU nurses, secretarial staff, nurse aides, and medical technicians. Residents were aware of the 360-degree assessment and participated voluntarily. The multiple raters' evaluations were then compared with those of the traditional faculty. Intraclass correlation coefficients were calculated to measure the reliability of ratings within each category of raters by the Pearson correlation coefficient. Results Four hundred twenty-nine rating forms were returned during the study period. Fifteen residents were evaluated. The response rate was 88%. Residents were ranked highest on availability and lowest on management skill. The average rating across all areas was high (8.23). The average mean rating across all items from PACU nurses was higher (8.34) than from secretarial staff (7.99, P > .08). The highest ranked resident ranked high with all raters and the lowest ranked was low with most raters. The intraclass coefficients of correlations were 0.8719, 0.7860, 0.8268, and 0.8575. Conclusions This type of resident assessment tool may be useful for PACU rotations. It appears to correlate with traditional faculty ratings, is feasible to use, and provides formative feedback to residents regarding their professionalism and interpersonal and communication skills.

    Objective The purpose of this paper is to report on the development, implementation, and evaluation of a Communication Skills Training (CST) module for inpatient oncology nurses on how to respond empathically to patients. Methods 248 nurses from a USA cancer center participated in a CST module on responding empathically to patients. Nurses completed pre- and post-training Standardized Patient Assessments (SPAs), a survey on their confidence in and intent to utilize skills taught, and a six-month post-training survey of self-reported use of skills. Results Results indicate that nurses were satisfied with the module, reporting that agreement or strong agreement to 5 out of 6 items assessing satisfaction 96.7%–98.0% of the time. Nurses’ self-efficacy in responding empathically significantly increased pre- to post-training. Additionally, nurses showed empathy skill improvement in the post-SPAs. Finally, 88.2% of nurses reported feeling confident in using the skills they learned post-training and reported an increase of 42–63% in the use of specific empathic skills. Conclusions A CST module for nurses in responding empathically to patients showed feasibility, acceptability, and improvement in self-efficacy as well as skill uptake. Practice implications This CST module provides an easily targeted intervention for improving nurse–patient communication and patient-centered care. PMID:26686992

    In recent years, there has been great interest in using hybrid spread-spectrum (HSS) techniques for commercial applications, particularly in the Smart Grid, in addition to their inherent uses in military communications. This is because HSS can accommodate high data rates with high link integrity, even in the presence of significant multipath effects and interfering signals. A highly useful form of this transmission technique for many types of command, control, and sensing applications is the specific code-related combination of standard direct sequence modulation with fast frequency hopping, denoted hybrid DS/FFH, wherein multiple frequency hops occur within a single data-bit time. In this paper, error-probability analyses are performed for a hybrid DS/FFH system over standard Gaussian and fading-type channels, progressively including the effects from wide- and partial-band jamming, multi-user interference, and varying degrees of Rayleigh and Rician fading. In addition, an optimization approach is formulated that minimizes the bit-error performance of a hybrid DS/FFH communication system and solves for the resulting system design parameters. The optimization objective function is non-convex and can be solved by applying the Karush-Kuhn-Tucker conditions. We also present our efforts toward exploring the design, implementation, and evaluation of a hybrid DS/FFH radio transceiver using a single FPGA. Numerical and experimental results are presented under widely varying design parameters to demonstrate the adaptability of the waveform for varied harsh smart grid RF signal environments.

    2015-11-01

    Several parameters for improving volatile metabolite analysis using headspace gas chromatography-mass spectrometry (GC-MS) analysis of volatile metabolites were evaluated in the framework of identification of mastitis-causing pathogens. Previous research showed that the results of such volatile metabolites analysis were comparable with those based on bacteriological culturing. The aim of this study was to evaluate the effect of several method changes on the applicability and potential implementation of this method in practice. The use of a relatively polar column is advantageous, resulting in a faster and less complex chromatographic setup with a higher resolving power yielding higher-quality data. Before volatile metabolite analysis is applied, a minimum incubation of 8h is advised, as reducing incubation time leads to less reliable pathogen identification. Application of GC-MS remained favorable compared with regular gas chromatography. The complexity and cost of a GC-MS system are such that this limits the application of the method in practice for identification of mastitis-causing pathogens. PMID:26342985

    Introduction: Implementation of a longitudinal curriculum for training in advanced communications skills represents an unmet need in most German medical faculties, especially in the 4rth and 5th years of medical studies. The CoMeD project (communication in medical education Düsseldorf) attempted to establish an interdisciplinary program to teach and to assess communicative competence in the 4th academic year. In this paper, we describe the development of the project and report results of its evaluation by medical students. Methods: Teaching objectives and lesson formats were developed in a multistage process. A teaching program for simulated patients (SP) was built up and continuous lecturer trainings were estabilshed. Several clinical disciplines co-operated for the purpose of integrating the communication training into the pre-existing clinical teaching curriculum. The CoMeD project was evaluated using feedback-forms after each course. Results: Until now, six training units for especially challenging communication tasks like “dealing with aggression” or “breaking bad news” were implemented, each unit connected with a preliminary tutorial or e-learning course. An OSCE (objective structured clinical examination) with 4 stations was introduced. The students’ evaluation of the six CoMeD training units showed the top or second-best rating in more than 80% of the answers. Discussion: Introducing an interdisciplinary communication training and a corresponding OSCE into the 4th year medical curriculum is feasible. Embedding communication teaching in a clinical context and involvement of clinicians as lecturers seem to be important factors for ensuring practical relevance and achieving high acceptance by medical students.

    2013-08-01

    Underwater wireless optical communication is a communication mode which uses light as an information carrier and water as transmission medium. As a result of the inherent characteristics of the light waves, underwater wireless optical communication has the advantages of high transmission rate, good security, and strong anti-interference ability. It is suitable for high-speed, short-range communication between underwater mobile vehicles. Underwater optical wireless communication system designed in this paper is composed of the omni-directional communication light source and the receiving system. In the omni-directional communication light source, the laser beams with small divergence angle of 532nm wavelength produced by modulated laser are expanded through a combination refraction-reflection solid and then obtain more than 2π space divergence angle. The paper use TRACEPRO simulation tool to help design a combination solid composed of the lens, conical reflector and parabolic reflector, and test in the air and underwater, the result shows that the effect is fine. Unlike in the air, light attenuation is heavy in the water and a large range of variations in light intensity at different distances appear during underwater optical communication. In order to overcome this problem, the paper use a small photomultiplier as the detection device, design the receiving system using the automatic gain control technique. Underwater wireless optical communication system designed in this paper has the characteristics of small size, low power dissipation and the omni-directional communication function, it is suitable for application in the UUV, AUV, Swimmer Delivery Vehicle (SDV) and other underwater mobile platform, it realizes point-to-point communications and point-to-multipoint communications.

  7. Developing Science Communication in Africa: Undergraduate and Graduate Students should be Trained and Actively Involved in Outreach Activity Development and Implementation

    Despite recent improvements in scientific research output from Africa, public understanding of science in many parts of the continent remains low. Science communication there is faced with challenges such as (i) lack of interest among some scientists, (ii) low availability of training programs for scientists, (iii) low literacy rates among the public, and (iv) multiplicity of languages. To address these challenges, new ways of training and motivating scientists to dialogue with non-scientists are essential. Developing communication skills early in researchers’ scientific career would be a good way to enhance their public engagement abilities. Therefore, a potentially effective means to develop science communication in Africa would be to actively involve trainee scientists (i.e., undergraduate and graduate students) in outreach activity development and delivery. These students are often enthusiastic about science, eager to develop their teaching and communication skills, and can be good mentors to younger students. Involving them in all aspects of outreach activity is, therefore, likely to be a productive implementation strategy. However, science communication training specifically for students and the involvement of these students in outreach activity design and delivery are lacking in Africa. Here, we argue that improving the training and involvement of budding scientists in science communication activities would be a good way to bridge the wide gap between scientists and the African public.

    Background Although there is growing evidence of the positive effects of Internet-based patient-provider communication (IPPC) services for both patients and health care providers, their implementation into clinical practice continues to be a challenge. Objective The 3 aims of this study were to (1) identify and compare barriers and facilitators influencing the implementation of an IPPC service in 5 hospital units using the Consolidated Framework for Implementation Research (CFIR), (2) assess the ability of the different constructs of CFIR to distinguish between high and low implementation success, and (3) compare our findings with those from other studies that used the CFIR to discriminate between high and low implementation success. Methods This study was based on individual interviews with 10 nurses, 6 physicians, and 1 nutritionist who had used the IPPC to answer messages from patients. Results Of the 36 CFIR constructs, 28 were addressed in the interviews, of which 12 distinguished between high and low implementation units. Most of the distinguishing constructs were related to the inner setting domain of CFIR, indicating that institutional factors were particularly important for successful implementation. Health care providers’ beliefs in the intervention as useful for themselves and their patients as well as the implementation process itself were also important. A comparison of constructs across ours and 2 other studies that also used the CFIR to discriminate between high and low implementation success showed that 24 CFIR constructs distinguished between high and low implementation units in at least 1 study; 11 constructs distinguished in 2 studies. However, only 2 constructs (patient need and resources and available resources) distinguished consistently between high and low implementation units in all 3 studies. Conclusions The CFIR is a helpful framework for illuminating barriers and facilitators influencing IPPC implementation. However, CFIR’s strength

    Communication training programs in oncology have demonstrated some efficacy to improve doctors' communication skills. The goal of our study was to evaluate the impact of such training in the particular context of phase I clinical trials. Self-satisfaction and self-efficacy scales evaluating doctor-patient communication was completed by 6 medical oncologists (3 juniors and 3 seniors) before and after their communication training for a total of sixty visits. Two types of visit have been distinguished: the visits between the oncologist and the patient alone (a dual situation) and those with a third party (a trilateral situation). For all the doctors in dual and trialateral situations, self-efficacy scores improved significantly after training. This improvement was more pronounced for juniors oncologists in trilateral situations. Before training, satisfactory scores were worst in duel versus trilateral situations (P=0.01). This was particularly pronounced for junior compared to senior doctors (P=0.035). After training, in trilateral situations, the satisfaction scores of junior doctors matched that of the senior doctors. The communication training programs appear to benefit junior oncologists to a greater extent in trilateral situations. PMID:25609484

    Goal of the KoMPASS project is to develop and test a training program that effectively improves oncologists' communication skills. The training draws with regard to concept, content and didactic methods to the specific challenges arising in interactions with cancer patients. Concept and didactical methods for an intensive training (KoMPASS Training) are being presented and complemented with experiences gathered during 39 trainings with 335 physicians, as well as findings from the training evaluation by participants. The participants' feedback after 4 months indicates successful transfer into clinical practice along with personal relief, improved self-efficacy, and communicative competencies. Even experienced practitioners ascribe high practical usefulness, and personal learning achievements to the KoMPASS training. The results of the concomitant study concerning self-efficacy, empathy, work-related stress and communicative competence will be published later. PMID:23677627

    This paper presents a modulation scheme in the time domain based on On-Off-Keying and proposes various compatible supports for different types of image sensors. The content of this article is a sub-proposal to the IEEE 802.15.7r1 Task Group (TG7r1) aimed at Optical Wireless Communication (OWC) using an image sensor as the receiver. The compatibility support is indispensable for Image Sensor Communications (ISC) because the rolling shutter image sensors currently available have different frame rates, shutter speeds, sampling rates, and resolutions. However, focusing on unidirectional communications (i.e., data broadcasting, beacons), an asynchronous communication prototype is also discussed in the paper. Due to the physical limitations associated with typical image sensors (including low and varying frame rates, long exposures, and low shutter speeds), the link speed performance is critically considered. Based on the practical measurement of camera response to modulated light, an operating frequency range is suggested along with the similar system architecture, decoding procedure, and algorithms. A significant feature of our novel data frame structure is that it can support both typical frame rate cameras (in the oversampling mode) as well as very low frame rate cameras (in the error detection mode for a camera whose frame rate is lower than the transmission packet rate). A high frame rate camera, i.e., no less than 20 fps, is supported in an oversampling mode in which a majority voting scheme for decoding data is applied. A low frame rate camera, i.e., when the frame rate drops to less than 20 fps at some certain time, is supported by an error detection mode in which any missing data sub-packet is detected in decoding and later corrected by external code. Numerical results and valuable analysis are also included to indicate the capability of the proposed schemes. PMID:27213396

    The network requirements of control systems in industrial applications increase day by day. The Internet based control system and various fieldbus systems have been designed in order to meet these requirements. This paper describes an Internet based control system with wireless fieldbus communication designed for distributed processes. The system was implemented as an experimental setup in a laboratory. In industrial facilities, the process control layer and the distance connection of the distributed control devices in the lowest levels of the industrial production environment are provided with fieldbus networks. In this paper, the Internet based control system that will be able to meet the system requirements with a new-generation communication structure, which is called wired/wireless hybrid system, has been designed on field level and carried out to cover all sectors of distributed automation, from process control, to distributed input/output (I/O). The system has been accomplished by hardware structure with a programmable logic controller (PLC), a communication processor (CP) module, two industrial wireless modules and a distributed I/O module, Motor Protection Package (MPP) and software structure with WinCC flexible program used for the screen of Scada (Supervisory Control And Data Acquisition), SIMATIC MANAGER package program ("STEP7") used for the hardware and network configuration and also for downloading control program to PLC.

    An efficient scheme is proposed to implement a quantum cloning machine in separate cavities based on a hybrid interaction between electron-spin systems placed in the cavities and an optical coherent pulse. The coefficient of the output state for the present cloning machine is just the direct product of two trigonometric functions, which ensures that different types of quantum cloning machine can be achieved readily in the same framework by appropriately adjusting the rotated angles. The present scheme can implement optimal one-to-two symmetric (asymmetric) universal quantum cloning, optimal symmetric (asymmetric) phase-covariant cloning, optimal symmetric (asymmetric) real-state cloning, optimal one-to-three symmetric economical real-state cloning, and optimal symmetric cloning of qubits given by an arbitrary axisymmetric distribution. In addition, photon loss of the qubus beams during the transmission and decoherence effects caused by such a photon loss are investigated.

    This paper describes the embedded system used to store and transfer large amounts of data in a multichannel data acquisition system for the GEM detector. The stored data is used for diagnostics purposes. System consists of an embedded mini ITX motherboard connected through the PCI Express (PCIe) link to a backplane FPGA. The backplane FPGA is connected through the SerDes/GTP links to (up to) 4 carrier boards. Each carrier board is connected to (up to) 4 FMC modules. System allows for a high speed data transfers between the ITX motherboard and the backplane or carrier modules. Due to high performance/reliability requirements, special care is taken for a proper data error correction/packet retransmission scenarios. There is also need for a proper communications diagnostics and a system addressing abstraction. Due to a distributed nature of described data acquisition system, data stored in DDR memory has to have a specific structure. This structure allows for a proper synchronisation of data between all the carrier boards.

    In this work some of the fundamentals of change management techniques to ensure the introduction of information and communication technologies in health organizations are analized. Managing change is aimed at redirecting the impact of any transformation process in the organizations towards a positive attitude and enthusiasm of those involved. That is, this paper analyzes the most important of all factors that must be managed in any project for change: the human factor. If a proper change management is a critical success factor in implementing new processes and systems of information and communication technologies (ICT) in an organization, when we faced with the introduction of new processes and interoperability systems between different organizations, cooperation, leadership and motivation of individuals focused on a common goal is absolutely imperative. This is the case of the new ICT systems being introduced in the Catalan Health System. Indeed, by definition of the model itself, in Catalonia, continuity of care, increased efficiency and effectiveness and quality improvement of projects as the clinical history shared, electronic prescriptions, or scanning medical imaging, require necessarily the definition of processes in which a large number of different health organizations, different in their law status, and whose own interests should converge towards the ICT systems and processes of health care so that the contribution of all parties can make a whole. The success of these projects, a reality nowadays, is due largely to the management of the human factor conducted continuously since its inception. PMID:20211352

    Background Surveillance data allow for analysis, providing public health officials and policy-makers with a basis for long-term priorities and timely information on possible outbreaks for rapid response (data for action). In this article we describe the considerations and technology behind a newly introduced public web tool in Sweden for easy retrieval of county and national surveillance data on communicable diseases. Methods The web service was designed to automatically present updated surveillance statistics of some 50 statutory notifiable diseases notified to the Swedish Institute for Infectious Disease Control (SMI). The surveillance data is based on clinical notifications from the physician having treated the patient and laboratory notifications, merged into cases using a unique personal identification number issued to all Swedish residents. The web service use notification data from 1997 onwards, stored in a relational database at the SMI. Results The web service presents surveillance data to the user in various ways; tabulated data containing yearly and monthly disease data per county, age and sex distribution, interactive maps illustrating the total number of cases and the incidence per county and time period, graphs showing the total number of cases per week and graphs illustrating trends in the disease data. The system design encompasses the database (storing the data), the web server (holding the web service) and an in-the-middle computer (to ensure good security standards). Conclusions The web service has provided the health community, the media, and the public with easy access to both timely and detailed surveillance data presented in various forms. Since it was introduced in May 2003, the system has been accessed more than 1,000,000 times, by more than 10,000 different viewers (over 12.600 unique IP-numbers). PMID:15191619

    With the development of computer networking, it has become desirable for users to interact with hosts and distributed operating systems from terminals not directly connected to those systems. Users and the institutions for which they work require distributed interactive services to take advantage of specialized software and hardware as well as economically priced computing capacity. A classical example of this requirement occurs in the ARPANET and it is becoming more widespread as local networks are interconnected. The problem of providing distributed interactive services is complicated by the heterogeneity of the systems involved. This heterogeneity is a characteristic of both the systems themselves as well as of the protocols they support. The general problems of interconnecting such systems have been previously investigated from the perspective of providing distributed interprocess communication (CEKA74, SUNC77). The framework established by this work is used to discuss the specific problem of providing distributed interactive services.

    The use of machine-to-machine (M2M) systems has spread among people seeking to connect devices with remote systems via the internet to provide services such as remote maintenance and remote energy management without human intervention. For the access network for M2M systems, not only security and immediacy, but also multi-service connectivity is required, which makes it possible to connect devices with multiple services. In this paper, a M2M proxy communication method is proposed as a communication method that achieves multi-service connectivity and security and immediacy at the same time. In the proposed method, a proxy server located between devices and application servers relays communications among them. In the relay processing, multi-service connectivity of the access network is achieved by performing access or exclusive control to devices. By adopting the M2M proxy communication method, the access network simultaneously provides multi-service connectivity, security and immediacy at low cost without introducing any special scheme into devices.

    This paper describes a proposal to add support for dynamic communicators to the MPI standard. This adds the ability to grow or shrink a specified communicator, under well specified circumstances. The goal is to make it possible for a new class of applications - long-running, mission-critical, loosely coupled applications, running in a highly dynamic environment - to use MPI libraries for their communications needs, and to enable HPC applications to adjust to changing system resources. Implementation analysis indicates that performance impact on existing high-performance MPI applications should be minimal, or non-existent. The changes to MPI implementations are expected to be well compartmentalized.

    Since 2009, the Federal government distributed over $29 billion to providers who were adopting compliant electronic health record (EHR) technology. With a focus on radiology, we explore how EHR technology impacts interoperability with referring clinicians' EHRs and patient engagement. We also discuss the high-level details of contributing supporting frameworks, specifically Direct messaging and health information service provider (HISP) technology. We characterized Direct messaging, a secure e-mail-like protocol built to allow exchange of encrypted health information online, and the new supporting HISP infrastructure. Statistics related to both the testing and active use of this framework were obtained from DirectTrust.org, an organization whose framework supports Direct messaging use by healthcare organizations. To evaluate patient engagement, we obtained usage data from a radiology-centric patient portal between 2014 and 2015, which in some cases included access to radiology reports. Statistics from 2013 to 2015 showed a rise in issued secure Direct addresses from 8724 to 752,496; a rise in the number of participating healthcare organizations from 667 to 39,751; and a rise in the secure messages sent from 122,842 to 27,316,438. Regarding patient engagement, an average of 234,679 patients per month were provided portal access, with 86,400 patients per month given access to radiology reports. Availability of radiology reports online was strongly associated with increased system usage, with a likelihood ratio of 2.63. The use of certified EHR technology and Direct messaging in the practice of radiology allows for the communication of patient information and radiology results with referring clinicians and increases patient use of patient portal technology, supporting bidirectional radiologist-patient communication.

    Background and objective Annotations to physical workspaces such as signs and notes are ubiquitous. When densely annotated, work areas become communication spaces. This study aims to characterize the types and purpose of such annotations. Methods A qualitative observational study was undertaken in two wards and the radiology department of a 440-bed metropolitan teaching hospital. Images were purposefully sampled; 39 were analyzed after excluding inferior images. Results Annotation functions included signaling identity, location, capability, status, availability, and operation. They encoded data, rules or procedural descriptions. Most aggregated into groups that either created a workflow by referencing each other, supported a common workflow without reference to each other, or were heterogeneous, referring to many workflows. Higher-level assemblies of such groupings were also observed. Discussion Annotations make visible the gap between work done and the capability of a space to support work. Annotations are repairs of an environment, improving fitness for purpose, fixing inadequacy in design, or meeting emergent needs. Annotations thus record the missing information needed to undertake tasks, typically added post-implemented. Measuring annotation levels post-implementation could help assess the fit of technology to task. Physical and digital spaces could meet broader user needs by formally supporting user customization, ‘programming through annotation’. Augmented reality systems could also directly support annotation, addressing existing information gaps, and enhancing work with context sensitive annotation. Conclusions Communication spaces offer a model of how work unfolds. Annotations make visible local adaptation that makes technology fit for purpose post-implementation and suggest an important role for annotatable information systems and digital augmentation of the physical environment.

    Introduction Practice guidelines can be used to support healthcare decision making. We sought to identify the use, and barriers to the implementation, of electronic based guidelines to support decision-making in maternal and child healthcare (MCH) and the rational use of medicines, in developing countries. Methods Graduates who had gained the Master of Public Health degree through the Peoples-uni (postgraduate public health education in developing countries) were sent an online survey questionnaire which had been piloted. Two reminders were sent to non-respondents at intervals of 10 days. Results were explored using descriptive analyses. Results 44 of the potential 48 graduates from 16 countries responded – most were from Africa. 82% and 89% of respondents were aware of guidelines on MCH and the rational use of medicines respectively. Electronic guidelines were more available in university hospitals than in provincial hospitals or rural care. All respondents thought that guidelines could improve the delivery of quality care, and 42 (95%) and 41 (93%) respectively thought that computers and mobile or smartphones could increase the use of guidelines in service delivery. Lack of access to computers, need to buy phone credit, need for training in the use of either computerized or phone based guidelines and fear of increased workload were potential barriers to use. Conclusion There is support for the use of electronic guidelines despite limited availability and barriers to use in developing countries. These findings, and other literature, provide a guide as to how the further development of ICT based guidelines may be implemented to improve health care decision making. PMID:25422718

    2014-01-01

    Background In resource-poor countries access to essential medicines, suboptimal prescribing and use of medicines are major problems. Health workers lack updated medical information and treatment support. Information and Communication Technology (ICT) could help tackle this. The impact of ICT on health systems in resource-poor countries is likely to be significant and transform the practice of medicine just as in high-income countries. However, research for finding the best way of doing this is needed. We aimed to assess current approaches to and use of ICT among health workers in two rural districts of Tanzania in relation to the current drug distribution practices, drug stock and continuing medical information (CME), as well as assessing the feasibility of using ICT to improve ordering and use of medicines. Methods This pilot study was conducted in 2010–2011, mapping the drug distribution chain in Tanzania, including problems and barriers. The study was conducted in Bunda and Serengeti districts, both part of the ICT4RD (ICT for rural development) project. Health workers involved in drug procurement and use at 13 health facilities were interviewed on use and knowledge of ICT, and their attitudes to its use in their daily work. They were also shown and interviewed about their thoughts on an android tablet application prototype for drug stock inventory and drug ordering, based on the Tanzanian Medical Stores Department (MSD) current paper forms. Results The main challenge was a stable supply of essential medicines. Drug supplies were often delayed and incomplete, resulting in stock-outs. All 20 interviewed health workers used mobile phones, 8 of them Smartphones with Internet connection. The Health workers were very positive to the tablet application and saw its potential in reducing drug stock-outs. They also expressed a great need and wish for CME by distance. Conclusion The tablet application was easily used and appreciated by health workers, and thus has the

    Objectives (1) To examine changes in women's awareness and utilisation of reproductive healthcare services in emergency settings following provision of interpersonal communication (IPC) and mass education campaigns, and (2) to describe factors associated with reproductive healthcare service use in internally displaced person (IDP) camps. Setting Three camps containing 88 984 IDPs in Darfur, Sudan. Participants 640 women aged 15−49 who had experienced pregnancy in the camp during the previous 2 years were enrolled in each of two independent cross-sectional surveys 26 months apart. Interventions IPC and mass education campaigns where community health workers disseminated information by home/shelter visits, clinic sessions, public meetings and other means to raise awareness and promote reproductive healthcare service use. Primary outcome measures Awareness of the existence of antenatal care (ANC) and tetanus toxoid (TT) vaccination services, reception of ANC and TT vaccination, place of delivery and use of postnatal care (PNC). Results The percentage of women who received home visits, and attended in-clinic sessions and public meetings increased from 61.6% to 86.7%, from 43.0% to 68.8%, and from 3.8% to 39.8%, respectively, between the initial and follow-up surveys. More women were aware of ANC (OR 18.6, 95% CI 13.1 to 26.5) and TT vaccination (OR 3.2, 95% CI 2.4 to 4.4) in the follow-up than the initial survey, after multivariable adjustment. More women received ≥3 ANC visits (OR 8.8, 95% CI 6.4 to 12.0) and ≥3 doses of TT (OR 2.5, 95% CI 1.9 to 3.3), delivered at a healthcare facility (OR 5.4, 95% CI 4.0 to 7.4) and received a PNC visit (OR 5.5, 95% CI 4.0 to 7.7) in the follow-up than in the initial survey, after multivariable adjustment. Conclusions Awareness about and utilisation of reproductive healthcare services were higher in the follow-up survey. An integrated IPC and mass education campaign is effective for improving women's reproductive health

Two of the five goals are related to science communications: produce the finest scientists and engineers for the 21st century, and raise scientific and technological literacy of all Americans. In addition to the guidance and goals set forth by the Administration, NASA has been mandated by Congress under the 1958 Space Act to 'provide for the widest practicable and appropriate dissemination concerning its activities and the results thereof'. In addition to addressing eight Goals and Plans which resulted from a January 1994 meeting between NASA and members of the broader scientific, education, and communications community on the Public Communication of NASA's Science, the Science Communications Working Group (SCWG) took a comprehensive look at the way the Agency communicates its science to ensure that any changes the Agency made were long-term improvements. The SCWG developed a Science Communications Strategy for NASA and a plan to implement the Strategy. This report outlines a strategy from which effective science communications programs can be developed and implemented across the agency. Guiding principles and strategic themes for the strategy are provided, with numerous recommendations for improvement discussed within the respective themes of leadership, coordination, integration, participation, leveraging, and evaluation.

    2002-06-01

    he design, architecture, and implementation for the high-throughput data transmission and high-performance computing,which are applicable for various real-time radar signal transmission applications over the data network, are presented. With a client-server model, the multiple processes and threads on the end systems operate simultaneously and collaborately to meet the real-time requirement. The design covers the Digitized Radar Signal (DRS) data acquisition and data transmission on the DRS server end as well as DRS data receiving, radar signal parameter computation and parameter transmission on the DRS receiver end. Generic packet and data structures for transmission and inter-process data sharing are constructed. The architecture was successfully implemented on Sun/Solaris workstations with dual 750 MHz UltraSPARC-III processors containing Gigabit Ethernet card. The comparison in transmission throughput over gigabit link between with computation and without computation clearly shows the importance of the signal processing capability on the end-to-end performance. Profiling analysis on the DRS receiver process shows the work-loaded functions and provides guides for improving computing capabilities.

    The purpose of this paper is to recommend regulatory guidance for reviewers examining computer communication systems used in nuclear power plants. The recommendations cover three areas important to these communications systems: system design, communication protocols, and communication media. The first area, system design, considers three aspects of system design--questions about architecture, specific risky design elements or omissions to look for in designs being reviewed, and recommendations for multiplexed data communication systems used in safety systems. The second area reviews pertinent aspects of communication protocol design and makes recommendations for newly designed protocols or the selection of existing protocols for safety system, information display, and non-safety control system use. The third area covers communication media selection, which differs significantly from traditional wire and cable. The recommendations for communication media extend or enhance the concerns of published IEEE standards about three subjects: data rate, imported hazards and maintainability.

    1985-11-12

    With the development of computer networking, it has become desirable for users to interact with hosts and distributed operating systems from terminals not directly connected to those systems. Users and the institutions for which they work require distributed interactive services to take advantage of specialized software and hardware as well as economically priced computing capacity. A classical example of this requirement occurs in the ARPANET and it is becoming more widespread as local networks are interconnected. The problem of providing distributed interactive services is complicated by the heterogeneity of the systems involved. This heterogeneity is a characteristic of both the systems themselves as well as of the protocols they support. The general problems of interconnecting such systems have been previously investigated from the perspective of providing distributed interprocess communication. The framework established by this work is used to discuss the specific problem of providing distributed interactive services. Heterogeneity is only one aspect of the distributed interactive services problem. The variety of situations in which distributed interactive services are required, operational requirements, security considerations, and human-factors requirements also play major roles in defining the exact nature of the problem.

Users and the institutions for which they work require distributed interactive services to take advantage of specialized software and hardware as well as economically priced computing capacity. A classical example of this requirement occurs in the ARPANET and it is becoming more widespread as local networks are interconnected. As discussed below, the problem of providing distributed interactive services is complicated by the heterogeneity of the systems involved. This heterogeneity is a characteristic of both the systems themselves as well as of the protocols they support. The general problems of interconnecting such systems have been previously investigated from the perspective of providing distributed interprocess communication (CEKA74,SUNC77). The framework, the widely used terms internetwork and internetwork system of internetwork node will be used to refer to the heterogeneous environment under discussion.

    The term Communication generally designate the transmission of a message of concepts, feelings or needs from a speaker to a receiver by means of verbal or no verbal language. The pragmatic approach to human communication has put in evidence a further implication of this concept: every behaviour therefore has a value even when it is not intentional. Recently, a more dynamic concept of communication has been elaborated where communication means communicative action. This interpretation is the starting point for the theory of the "communicative acting" and subsequently of the so called discourse ethic elaborated by J. Habermas. PMID:20499038

    Health communication is an evolving field. There is evidence that communication can be an effective tool, if utilized in a carefully planned and integrated strategy, to influence the behaviours of populations on a number of health issues, including vaccine hesitancy. Experience has shown that key points to take into account in devising and implementing a communication plan include: (i) it is necessary to be proactive; (ii) communication is a two-way process; (iii) knowledge is important but not enough to change behaviour; and (iv) communication tools are available and can be selected and used creatively to promote vaccine uptake. A communication strategy, incorporating an appropriate selection of the available communication tools, should be an integral part of every immunization programme, addressing the specific factors that influence hesitancy in the target populations.

    The Radiology Department at the University of Pennsylvania is in the process of clinically testing its PACS implementation. The PACS implementation has been built around a Vortech Image Archival and Retrieval System (IARS) with a 140-platter optical jukebox. The Vortech IARS provides archival services only. A set of software modules have been developed in-house that allow the system to function as a digital film library. The current implementation allows connectivity to a RIS (DECrad), supports the routing of images to two intensive care units, and allows image acquisition from a Du Pont FD2000 laser scanner and two GE SIGNA MR units. All process-to-process communication follows the ACR/NEMA 2.0 protocol. The proposed folder extensions to ACR/NEMA 2.0 are being utilized for sending information to the display nodes. The system has been running clinically for about three months. Details of the design, implementation, and functionality of the PACS are presented.

    Unprecedented growth of required telecommunications services and telecommunications applications change the way the INL does business today. High speed connectivity compiled with a high demand for telephony and network services requires a robust communications infrastructure.   The current state of the MFC communication infrastructure limits growth opportunities of current and future communication infrastructure services. This limitation is largely due to equipment capacity issues, aging cabling infrastructure (external/internal fiber and copper cable) and inadequate space for telecommunication equipment. While some communication infrastructure improvements have been implemented over time projects, it has been completed without a clear overall plan and technology standard.   This document identifies critical deficiencies with the current state of the communication infrastructure in operation at the MFC facilities and provides an analysis to identify needs and deficiencies to be addressed in order to achieve target architectural standards as defined in STD-170. The intent of STD-170 is to provide a robust, flexible, long-term solution to make communications capabilities align with the INL mission and fit the various programmatic growth and expansion needs.

    Fordyce, Samuel W.

    Progress in the designs and performance capabilities of communications satellites is traced from the Echo 1 Al-coated mylar balloon in 1960 to systems planned for the 1990s and beyond. The services allowed with the passive balloon concept were too limited and led to Telstar spacecraft, with 600 voice channels, being placed in elliptical orbits. Geosynchronous communications began in 1963 with the Syncom satellite, which also carried television signals. The evolution of subsequent Intelsat and ANIK satellites is described, as are features of the Marisat, Marecs, and the DBS systems. The near-term capabilities for DBS, advanced communications satellites using TDMA techniques, and mobile communications systems are summarized, along with the NASA ACTS and MSAT-X satellites for exploring the necessary technologies. The roles the Space Station and unmanned GEO platforms will play in future satellite communications are discussed.

  2. Patient-doctor communication.

    Communication is an important component of patient care. Traditionally, communication in medical school curricula was incorporated informally as part of rounds and faculty feedback, but without a specific or intense focus on skills of communicating per se. The reliability and consistency of this teaching method left gaps, which are currently getting increased attention from medical schools and accreditation organizations. There is also increased interest in researching patient-doctor communication and recognizing the need to teach and measure this specific clinical skill. In 1999, the Accreditation of Council for Graduate Medical Education implemented a requirement for accreditation for residency programs that focuses on "interpersonal and communications skills that result in effective information exchange and teaming with patients, their families, and other health professionals." The National Board of Medical Examiners, Federation of State Medical Boards. and the Educational Commission for Foreign Medical Graduates have proposed an examination between the. third and fourth year of medical school that "requires students to demonstrate they can gather information from patients, perform a physical examination, and communicate their findings to patients and colleagues" using standardized patients. One's efficiency and effectiveness in communication can be improved through training, but it is unlikely that any future advances will negate the need and value of compassionate and empathetic two-way communication between clinician and patient. The published literature also expresses belief in the essential role of communication. "It has long been recognized that difficulties in the effective delivery of health care can arise from problems in communication between patient and provider rather than from any failing in the technical aspects of medical care. Improvements in provider-patient communication can have beneficial effects on health outcomes". A systematic review of

  4. Sources of variability in human communicative skills

    When established communication systems cannot be used, people rapidly create novel systems to modify the mental state of another agent according to their intentions. However, there are dramatic inter-individual differences in the implementation of this human competence for communicative innovation. Here we characterize psychological sources of inter-individual variability in the ability to build a shared communication system from scratch. We consider two potential sources of variability in communicative skills. Cognitive traits of two individuals could independently influence their joint ability to establish a communication system. Another possibility is that the overlap between those individual traits influences the communicative performance of a dyad. We assess these possibilities by quantifying the relationship between cognitive traits and behavior of communicating dyads. Cognitive traits were assessed with psychometric scores quantifying cooperative attitudes and fluid intelligence. Competence for implementing successful communicative innovations was assessed by using a non-verbal communicative task. Individual capacities influence communicative success when communicative innovations are generated. Dyadic similarities and individual traits modulate the type of communicative strategy chosen. The ability to establish novel communicative actions was influenced by a combination of the communicator's ability to understand intentions and the addressee's ability to recognize patterns. Communicative pairs with comparable systemizing abilities or behavioral inhibition were more likely to explore the search space of possible communicative strategies by systematically adding new communicative behaviors to those already available. No individual psychometric measure seemed predominantly responsible for communicative success. These findings support the notion that the human ability for fast communicative innovations represents a special type of complex collaborative activity

    Scientific debates in modern societies often blur the lines between the science that is being debated and the political, moral, and legal implications that come with its societal applications. This manuscript traces the origins of this phenomenon to professional norms within the scientific discipline and to the nature and complexities of modern science and offers an expanded model of science communication that takes into account the political contexts in which science communication takes place. In a second step, it explores what we know from empirical work in political communication, public opinion research, and communication research about the dynamics that determine how issues are debated and attitudes are formed in political environments. Finally, it discusses how and why it will be increasingly important for science communicators to draw from these different literatures to ensure that the voice of the scientific community is heard in the broader societal debates surrounding science.

    A technology utilization project led to the commercial adaptation of a Space Shuttle Orbiter wireless infrared voice communications system. The technology was adapted to a LAN system by Wilton Industries, one of the participants. Because the system is cable-free, installation charges are saved, and it can be used where cable is impractical. Resultant products include the IRplex 6000. Transceivers can be located anywhere and can include mobile receivers. The system provides wireless LAN coverage up to 44,000 square feet. applications include stock exchange communications, trade shows, emergency communications, etc.

    Few would dispute that the science of particle physics in the United States has reached a crossroads. Policies, decisions, and events of the coming decade will be critical in determining whether the United States continues to carry out a competitive program of leadership in this field of fundamental science. The field of particle physics has responded to this reality by fundamentally changing its model of communication from “business as usual” to a strategic and collaborative method that is clearly focused on achieving a healthy future for the science. Over the past half-dozen years, the particle physics community has gone from being an oft-cited example of how not to communicate effectively, to a frequently cited—and emulated—model for science communication. This review outlines the new approach toward communication in particle physics and then goes into detail about three case studies.

    Science Communication plays a crucial role in education and in the public understanding of science. It shortens the distance between scientific research, the school and the general public. Astronomy has a privileged position in the process of science communication since it embraces different areas of knowledge such as mathematics, physics, chemistry, geology and biology. It is capable of attracting a vast audience and is a powerful tool for science popularization. Nowadays, science must compete with many other subjects for a place in the media and in the public's attention. This paradigm has raised the standards and demands for science communication and pushed it into professionalism. The International Year of Astronomy 2009 (IYA2009) is one of the biggest challenges for astronomy communication. There are two key elements in the communication strategy that are often forgotten: detailed description of objectives and goals and evaluation of the results. They are in opposite poles of the communication strategy, but must both be taken into account from the beginning of any activity. In this paper we will present some guidelines that can be helpful in the initial planning of outreach activities, as well as the evaluation of its results.

    In the photo at bottom right, a U.S. Park Police officer is demonstrating a battery-powered communications system, sufficiently compact to be packed in a briefcase-size container, which can send and receive signals over great distances by means of satellite relay. Key to the system's efficacy is the high-powered transmitting and receiving equipment aboard such NASA satellites as the Applications Technology Satellite6 (ATS-6) and the joint U.S.-Canadian Communications Technology Satellite (CTS); this enables the briefcase communicator to pick up satellite-relayed signals by means of the small hook-on antenna shown instead of the more elaborate-ground equipment customarily needed. Developed by NASA's Goddard Space Flight Center, the communicator is intended for use in emergency situations. It has utility, for example, in disasters, such as floods and hurricanes, where power failure disrupts conventional communications; for on-the-spot transmissions from major accident sites; or in remote areas where no other means of communication exists

  17. Agent Communications using Distributed Metaobjects

    SciTech Connect

    Goldsmith, Steven Y.; Spires, Shannon V.

    1999-06-10

    There are currently two proposed standards for agent communication languages, namely, KQML (Finin, Lobrou, and Mayfield 1994) and the FIPA ACL. Neither standard has yet achieved primacy, and neither has been evaluated extensively in an open environment such as the Internet. It seems prudent therefore to design a general-purpose agent communications facility for new agent architectures that is flexible yet provides an architecture that accepts many different specializations. In this paper we exhibit the salient features of an agent communications architecture based on distributed metaobjects. This architecture captures design commitments at a metaobject level, leaving the base-level design and implementation up to the agent developer. The scope of the metamodel is broad enough to accommodate many different communication protocols, interaction protocols, and knowledge sharing regimes through extensions to the metaobject framework. We conclude that with a powerful distributed object substrate that supports metaobject communications, a general framework can be developed that will effectively enable different approaches to agent communications in the same agent system. We have implemented a KQML-based communications protocol and have several special-purpose interaction protocols under development.

    We are in an era of rapidly changing communication media, which is driving a major evolution in the modes of communicating science. In the past, a mainstay of scientific communication in popular media was through science “translators”; science journalists and presenters. These have now nearly disappeared and are being replaced by widespread dissemination through, e.g., the internet, blogs, YouTube and journalists who often have little scientific background and sharp deadlines. Thus, scientists are required to assume increasing responsibility for translating their scientific findings and calibrating their communications to non-technical audiences, a task for which they are often ill prepared, especially when it comes to controversial societal issues such as tobacco, evolution, and most recently climate change (Oreskes and Conway 2010). Such issues have been politicized and hi-jacked by ideological belief systems to such an extent that constructive dialogue is often impossible. Many scientists are excellent communicators, to their peers. But this requires careful attention to detail and logical explanation, open acknowledgement of uncertainties, and dispassionate delivery. These qualities become liabilities when communicating to a non-scientific audience where entertainment, attention grabbing, 15 second sound bites, and self assuredness reign (e.g. Olson 2009). Here we report on a program initiated by NCAR and UCAR to develop new approaches to science communication and to equip present and future scientists with the requisite skills. If we start from a sound scientific finding with general scientific consensus, such as the warming of the planet by greenhouse gases, then the primary emphasis moves from the “science” to the “art” of communication. The art cannot have free reign, however, as there remains a strong requirement for objectivity, honesty, consistency, and above all a resistance to advocating particular policy positions.

    "Half the world is composed of people who have something to say and can't, and the other half who have nothing to say and keep on saying it." - Robert Frost In this age of digital soap boxes and half-truths, the importance of geoscientists as communicators cannot be underestimated, nor has there been a more important time for researchers to stand up and demand to be heard. So why is there still such an overwhelming public perception that scientists are poor communicators, and what can we do to change this? In this work I will present an overview of a number of successful initiatives that have been developed at Manchester Metropolitan University, and beyond, to ensure that science is communicated to a large variety of people, from policy makers to members of the local community. I will also present an overview of the emerging field of Science Communication, how it has changed in the past few decades from a one-way diatribe to a two-way discussion, and how this represents a possible new direction and career path for geoscientists. Anne Roe, the noted American psychologist, told us, "nothing in science has any value to society if it is not communicated." As geoscientists, we have a professional and moral obligation to ensure that we not only research the facts, but that we also present them in an informative and engaging manner, so that the rest of humanity can benefit from the fruits of our labour.

    Today's advanced network management systems can automate many aspects of the tactical networking operations within a military domain. However, automation of joint and coalition tactical networking across multiple domains remains challenging. Due to potentially conflicting goals and priorities, human agreement is often required before implementation into the network operations. This is further complicated by incompatible network management systems and security policies, rendering it difficult to implement automatic network management, thus requiring manual human intervention to the communication protocols used at various network routers and endpoints. This process of manual human intervention is tedious, error-prone, and slow. In order to facilitate a better solution, we are pursuing a technology which makes network management automated, reliable, and fast. Automating the negotiation of the common network communication parameters between different parties is the subject of this paper. We present the technology that enables inter-force dynamic communication resource negotiations to enable ad-hoc inter-operation in the field between force domains, without pre-planning. It also will enable a dynamic response to changing conditions within the area of operations. Our solution enables the rapid blending of intra-domain policies so that the forces involved are able to inter-operate effectively without overwhelming each other's networks with in-appropriate or un-warranted traffic. It will evaluate the policy rules and configuration data for each of the domains, then generate a compatible inter-domain policy and configuration that will update the gateway systems between the two domains.

    This article provides a general introduction to implementation science—the discipline that studies the implementation process of research evidence—in the context of hospice and palliative care. By discussing how implementation science principles and frameworks can inform the design and implementation of intervention research, we aim to highlight how this approach can maximize the likelihood for translation and long-term adoption in clinical practice settings. We present 2 ongoing clinical trials in hospice that incorporate considerations for translation in their design and implementation as case studies for the implications of implementation science. This domain helps us better understand why established programs may lose their effectiveness over time or when transferred to other settings, why well-tested programs may exhibit unintended effects when introduced in new settings, or how an intervention can maximize cost-effectiveness with strategies for effective adoption. All these challenges are of significance to hospice and palliative care, where we seek to provide effective and efficient tools to improve care services. The emergence of this discipline calls for researchers and practitioners to carefully examine how to refine current and design new and innovative strategies to improve quality of care. PMID:23558847

We measure 1. single processor performance, 2. point-to-point communication performance, 3. performance variation as a function of communication protocols and transport layer for collective communication routines, and 4. performance sensitivity of full application code to choice of parallel implementation. We also compare and contrast these results with similar results for the previous generation of parallel platforms, evaluating how the relative importance of communication performance has changed.

We argue that the versatility of software-defined quantum communication test beds can be useful for exploring new regimes in communication and rapidly prototyping new systems.

    GOSIP (Government Open Systems Interconnection Profile) is a subset of ISO`s OSI protocol standards relevant to US Government operations. As a Federal Information Processing Standard (FIPS), GOSIP is required by law for all Federal agencies. Mandatory standards-based communications products are required when purchasing functionality equivalent to what is specified in GOSIP. This unprecedented requirement by the Federal government has caused considerable confusion concerning practical implementation of relatively immature and untested technologies. Many organizations already have substantial investment in one or more proprietary network architectures. This paper examines issues associated with conversion to the GOSIP system.

    We propose a novel language construct called communicating transactions, obtained by dropping the isolation requirement from classical transactions, which can be used to model automatic error recovery in distributed systems. We extend CCS with this construct and give a simple semantics for the extended calculus, called TransCCS. We develop a behavioural theory which is sound and complete with respect to the may-testing preorder, and use it to prove interesting laws and reason compositionally about example systems. Finally, we prove that communicating transactions do not increase the observational power of processes; thus CCS equivalences are preserved in the extended language.

    The increase in demand for satellite communications services brought about shortages in available transponder capacity, especially at C-band. Interest shifted to the Ku-band frequency and currently carriers are rapidly moving to secure orbital slots for future satellite development. Projections of communications service demands over the next decade indiate growth in voice, data, and video services such that saturation of both C-band and Ku-band will occur by 1990. Emphasis must and will shift to Ka-band (20/30 GHz) frequency for fixed-satellite service. Advanced technologies such as multibeam antennas coupled with on-board satellite switching to allow implementation in this band of very high capacity satellite systems will be applied to meet the demand. Satellite system concepts that are likely in the 1990's and are likely to bring a new dimension to satellite delivered communication service are presented. The NASA 30/20 GHz communications satellite system demonstration program is discussed with emphasis on the related technology development.

A 450 MHz cellular system began operations in Scandinavian countries in 1981, and two 900 MHz systems entered service in the United Kingdom in 1985. Similar systems are being implemented in most European countries. Coding and access schemes are being studied for a pan-European 900 MHz system. Satellites can complement the system by providing service in coastal waters, regions of economic importance to Europe, and sparsely-populated areas. Improvements in vocodors, receiver gain, and technologies for the less-congested 14/11 or 30/20 GHz voice and data links are necessary. ESA studies with the Marecs satellite, preparatory to launch of a prototype mobile communication link, are summarized.

    The objective of the Communications Technology Program is to enable data transmission to and from low Earth orbit, geostationary orbit, and solar and deep space missions. This can be achieved by maintaining an effective, balances effort in basic, applied, and demonstration prototype communications technology through work in theory, experimentation, and components. The program consists of three major research and development discipline areas which are: microwave and millimeter wave tube components; solid state monolithic integrated circuit; and free space laser communications components and devices. The research ranges from basic research in surface physics (to study the mechanisms of surface degradation from under high temperature and voltage operating conditions which impacts cathode tube reliability and lifetime) to generic research on the dynamics of electron beams and circuits (for exploitation in various micro- and millimeter wave tube devices). Work is also performed on advanced III-V semiconductor materials and devices for use in monolithic integrated analog circuits (used in adaptive, programmable phased arrays for microwave antenna feeds and receivers) - on the use of electromagnetic theory in antennas and on technology necessary for eventual employment of lasers for free space communications for future low earth, geostationary, and deep space missions requiring high data rates with corresponding directivity and reliability.

  7. Astronomy Communication

    2003-07-01

    Astronomers communicate all the time, with colleagues of course, but also with managers and administrators, with decision makers and takers, with social representatives, with the news media, and with the society at large. Education is naturally part of the process. Astronomy communication must take into account several specificities: the astronomy community is rather compact and well organized world-wide; astronomy has penetrated the general public remarkably well with an extensive network of associations and organizations of aficionados all over the world. Also, as a result of the huge amount of data accumulated and by necessity for their extensive international collaborations, astronomers have pioneered the development of distributed resources, electronic communications and networks coupled to advanced methodologies and technologies, often much before they become of common world-wide usage. This book is filling up a gap in the astronomy-related literature by providing a set of chapters not only of direct interest to astronomy communication, but also well beyond it. The experts contributing to this book have done their best to write in a way understandable to readers not necessarily hyperspecialized in astronomy nor in communication techniques while providing specific detailed information, as well as plenty of pointers and bibliographic elements. This book will be very useful for researchers, teachers, editors, publishers, librarians, computer scientists, sociologists of science, research planners and strategists, project managers, public-relations officers, plus those in charge of astronomy-related organizations, as well as for students aiming at a career in astronomy or related space science.

    New methods and approaches are being tried and evaluated with the goal of increasing productivity and quality. The underlying concept in all of these approaches, methods or processes is that people require interactive communication to maximize the organization's strengths and minimize impediments to productivity improvement. This paper examines Bendix Field Engineering Corporation's organizational structure and experiences with employee involvement programs. The paper focuses on methods Bendix developed and implemented to open lines of communication throughout the organization. The Bendix approach to productivity and quality enhancement shows that interactive communication is critical to the successful implementation of any productivity improvement program. The paper concludes with an examination of the Bendix methodologies which can be adopted by any corporation in any industry.

    1984-01-01

    A research program to determine and demonstrate the principles to be followed in the design of local communication networks as typified by local area networks, private branch exchanges and internetted collections of such structures is planned. Two fundamental assumptions distinguish the research from much of the ongoing work: (1) a single integrated system is to provide a set of highly diverse communication services such as interactive terminal service, data base access, file transfers, graphics, and voice and video; and (2) a single mode optical fiber links with very wide bandwidths is economical. These assumptions are not satisfied by the networks now being designed, but based upon the perceived trend toward such integrated diverse services and the declining cost of single mode fiber technology. It is planned for the research to involve theoretical, experimental, and design activities.

    NASA Astrophysics Data System (ADS)

    Zwerger, M.; Briegel, H. J.; Dür, W.

    2016-03-01

    We review and discuss the potential of using measurement-based elements in quantum communication schemes, where certain tasks are realized with the help of entangled resource states that are processed by measurements. We consider long-range quantum communication based on the transmission of encoded quantum states, where encoding, decoding and syndrome readout are implemented using small-scale resource states. We also discuss entanglement-based schemes and consider measurement-based quantum repeaters. An important element in these schemes is entanglement purification, which can also be implemented in a measurement-based way. We analyze the influence of noise and imperfections in these schemes and show that measurement-based implementation allows for very large error thresholds of the order of 10 % noise per qubit and more. We show how to obtain optimal resource states for different tasks and discuss first experimental realizations of measurement-based quantum error correction using trapped ions and photons.

  5. Coherent communication with linear optics

    Wilde, Mark M.; Brun, Todd A.; Dowling, Jonathan P.; Lee, Hwang

    2008-02-15

    We show how to implement several continuous-variable coherent protocols with linear optics. Noise can accumulate when implementing each coherent protocol with realistic optical devices. Our analysis bounds the level of noise accumulation. We highlight the connection between a coherent channel and a nonlocal quantum nondemolition interaction and give two new protocols that implement a coherent channel. One protocol is superior to a previous method for a nonlocal quantum nondemolition interaction because it requires fewer communication resources. We then show how continuous-variable coherent superdense coding implements two nonlocal quantum nondemolition interactions with a quantum channel and bipartite entanglement. We finally show how to implement continuous-variable coherent teleportation experimentally and provide a way to verify the correctness of its operation.

  6. Evaluation of interprofessional education: lessons learned through the development and implementation of an interprofessional seminar on team communication for undergraduate health care students in Heidelberg – a project report

    Introduction: This project report describes the development, “piloting” and evaluation of an interprofessional seminar on team communication bringing together medical students and Interprofessional Health Care B.Sc. students at the Medical Faculty of Heidelberg University, Germany. Project Description: A five-member interprofessional team collaborated together on this project. Kolb’s experiential learning concept formed the theoretical foundation for the seminar, which explored three interprofessional competency areas: team work, communication and values/ethics. Evaluation for the purposes of quality assurance and future curricula development was conducted using two quantitative measures: descriptive analysis of a standardized course evaluation tool (EvaSys) ANOVA analysis of the German translation of the University of the West of England Interprofessional Questionnaire (UWE-IP-D). Results: The key finding from the standardized course evaluation was that the interprofessional seminars were rated more positively [M=2.11 (1 most positive and 5 most negative), SD=1, n=27] than the monoprofessional seminars [M=2.55, SD=0.98, n=90]. The key finding from the UWE-IP-D survey, comparing pre and post scores of the interprofessional (IP) (n=40) and monoprofessional (MP) groups (n=34), was that significant positive changes in mean scores for both groups towards communication, teamwork and interprofessional learning occurred. Conclusions: Lessons learnt included: a) recognising the benefit of being pragmatic when introducing interprofessional education initiatives, which enabled various logistical and attitudinal barriers to be overcome; b) quantitative evaluation of learning outcomes alone could not explain positive responses or potential influences of interprofessional aspects, which highlighted the need for a mixed methods approach, including qualitative methods, to enrich judgment formation on interprofessional educational outcomes.

  7. Fusion Implementation

    SciTech Connect

    2002-02-20

    If a fusion DEMO reactor can be brought into operation during the first half of this century, fusion power production can have a significant impact on carbon dioxide production during the latter half of the century. An assessment of fusion implementation scenarios shows that the resource demands and waste production associated with these scenarios are manageable factors. If fusion is implemented during the latter half of this century it will be one element of a portfolio of (hopefully) carbon dioxide limiting sources of electrical power. It is time to assess the regional implications of fusion power implementation. An important attribute of fusion power is the wide range of possible regions of the country, or countries in the world, where power plants can be located. Unlike most renewable energy options, fusion energy will function within a local distribution system and not require costly, and difficult, long distance transmission systems. For example, the East Coast of the United States is a prime candidate for fusion power deployment by virtue of its distance from renewable energy sources. As fossil fuels become less and less available as an energy option, the transmission of energy across bodies of water will become very expensive. On a global scale, fusion power will be particularly attractive for regions separated from sources of renewable energy by oceans.

  8. Risk Management Implementation Tool

    Wright, Shayla L.

    2004-01-01

    Continuous Risk Management (CM) is a software engineering practice with processes, methods, and tools for managing risk in a project. It provides a controlled environment for practical decision making, in order to assess continually what could go wrong, determine which risk are important to deal with, implement strategies to deal with those risk and assure the measure effectiveness of the implemented strategies. Continuous Risk Management provides many training workshops and courses to teach the staff how to implement risk management to their various experiments and projects. The steps of the CRM process are identification, analysis, planning, tracking, and control. These steps and the various methods and tools that go along with them, identification, and dealing with risk is clear-cut. The office that I worked in was the Risk Management Office (RMO). The RMO at NASA works hard to uphold NASA s mission of exploration and advancement of scientific knowledge and technology by defining and reducing program risk. The RMO is one of the divisions that fall under the Safety and Assurance Directorate (SAAD). I worked under Cynthia Calhoun, Flight Software Systems Engineer. My task was to develop a help screen for the Continuous Risk Management Implementation Tool (RMIT). The Risk Management Implementation Tool will be used by many NASA managers to identify, analyze, track, control, and communicate risks in their programs and projects. The RMIT will provide a means for NASA to continuously assess risks. The goals and purposes for this tool is to provide a simple means to manage risks, be used by program and project managers throughout NASA for managing risk, and to take an aggressive approach to advertise and advocate the use of RMIT at each NASA center.

  9. Practical secure quantum communications

    NASA Astrophysics Data System (ADS)

    Diamanti, Eleni

    2015-05-01

    We review recent advances in the field of quantum cryptography, focusing in particular on practical implementations of two central protocols for quantum network applications, namely key distribution and coin flipping. The former allows two parties to share secret messages with information-theoretic security, even in the presence of a malicious eavesdropper in the communication channel, which is impossible with classical resources alone. The latter enables two distrustful parties to agree on a random bit, again with information-theoretic security, and with a cheating probability lower than the one that can be reached in a classical scenario. Our implementations rely on continuous-variable technology for quantum key distribution and on a plug and play discrete-variable system for coin flipping, and necessitate a rigorous security analysis adapted to the experimental schemes and their imperfections. In both cases, we demonstrate the protocols with provable security over record long distances in optical fibers and assess the performance of our systems as well as their limitations. The reported advances offer a powerful toolbox for practical applications of secure communications within future quantum networks.

    Zheng, Xiangquan; Wen, Xiang; Zhang, Yongding

    2011-10-01

    To support a wide range of different grid applications in environments where various heterogeneous communication networks coexist, it is important to enable advanced capabilities in on-demand and dynamical integration and efficient co-share with cross-domain heterogeneous communication resource, thus providing communication services which are impossible for single communication resource to afford. Based on plug-and-play co-share and soft integration with communication resource, Grid-enabled communication network is flexibly built up to provide on-demand communication services for gird applications with various requirements on quality of service. Based on the analysis of joint job and communication resource scheduling in grid-enabled communication networks (GECN), this paper presents a cross multi-domain communication resource cooperatively scheduling method and describes the main processes such as traffic requirement resolution for communication services, cross multi-domain negotiation on communication resource, on-demand communication resource scheduling, and so on. The presented method is to afford communication service capability to cross-domain traffic delivery in GECNs. Further research work towards validation and implement of the presented method is pointed out at last.

    As the space era approaches, the importance of including space science in the general curriculum and communicating space science to the general public is becoming extremely important. The paper, points out that the inclusion of more space education in the school curriculum and to the general public will increase awareness and interest in the new developments of space exploration. The paper covers some of the many science communication projects under taken by students in the UK. One such success was the contribution to National Science Week by the University of Leicester in conjunction with UK Students for the Exploration and Development of Space (UKSEDS - a national body of students promoting space education). Children between the ages of 9-12 were taught about the solar system using enjoyable experiments. The paper will also cover other UKSEDS activities and projects. On a more worldwide scale `Under African Skies' is a fairly new and immensely exciting project (part of Cosmos Education): the participants last year including UKSEDS members travelled from school to school in Africa helping teachers and taking part in classes, including many in astronomy and physics. The paper also explains the benefits of the National Space Centre in the UK, the involvement of the University of Leicester in SSETI (Student Space Exploration and Technology Initiative) and Space School.

    AIMFAST is a software code used to align facets on a dish concentrator to a specific aimpoint strategy to minimize peak fluxes and maximize system optical performance. AIMFAST uses a large monitor or projections screen to display fringe patterns, and a machine vision camera to image the reflection of these patterns in the subject dish mirrors. From these images, a detailed map of surface normals can be generated and compared to design or fitted mirror shapes. This fitted comparison is then used to develop a single vector representing the orientation of the facets relative to the design orientation, and provide near-real-time adjustment information to a communicating computer. The communicating computer can display adjustments or directly interface with adjustment tools. The software for the communicating computer is specific to the implementation and is not a part of AIMFAST.

    2016-02-01

    The European Union (EU) Broiler Directive (2007/43/EC) is unique amongst current EU Directives, which address animal welfare, in that it uses outcome data collected at abattoirs and on farm to monitor on-farm broiler welfare and vary the maximum permitted stocking density on farm. In this study, we describe how, by bringing together personnel from the competent authorities in 22 member states (MSs) who have responsibility for implementing the Directive, and engaging in exchange of information and technical methods regarding the Broiler Directive, it has been possible to identify differences in approach with regard to 'what data is being collected, and by whom' across EU MSs. Online questionnaires and workshop exercises enabled us to identify priority areas for knowledge transfer and training. For example, foot pad dermatitis, hock burn, dead on arrival and total rejections (birds rejected as unfit for human consumption by the meat inspection staff at slaughter) were identified by the MSs as measures of medium-to-low priority in terms of knowledge transfer because there are assessment methods for these conditions that are already well accepted by competent authorities. On the other hand, breast lesions, cellulitis, emaciation, joint lesions, respiratory problems, scratches, wing fractures and a number of environmental measures were identified as having high priority in terms of knowledge transfer. The study identified that there is significant variability in the stage of implementation between MSs, and responses from the participating MSs indicated that sharing of guidance and technical information between MSs may be of value in the future set-up process for those MSs engaged in implementation of the Directive.

  3. Environmental risk communication as an educational process

    NASA Astrophysics Data System (ADS)

    Schottenfeld, Faith

    The purpose of this study was to explore the dynamics of the environmental risk communication process. The goal was to look at the totality of the process by examining the different components: entry to communication (what brings people into the process), maintenance of communication (behaviors of participants, pathways to successful risk communication, barriers to successful risk communication, characteristics of the dialogue) and outcomes of risk communication (what has been learned, what moves the process to social action, what else can come of the process). Interviews and critical incidents were used to explore the experiences of risk communicators in four different practice settings: academia, industry/trade groups, community-based organizations and government. Twenty-four people completed critical incident stories and sixteen participated in in-depth interviews. Data were coded and analyzed for themes. Findings illustrated that successful risk communication results from a deliberative, or purposeful process. This process includes a systematic approach to identifying and inviting people to participate, while considering specific motivating factors that affect participation. Risk communication is maintained by creating and nurturing structured forums for dialogue by acknowledging the varying perspectives of the people who participate and the contextual settings of environmental risks. The result of effective dialogue may range from increased knowledge, to transformative learning to social action and policy change. The researcher recommended that a multi-disciplinary team including risk communicators, adult educators and scientists can work most effectively to plan, implement and evaluate a risk communication process.

  4. ATCOM: Automatically Tuned Collective Communication System for SMP Clusters

    Conventional implementations of collective communications are based on point-to-point communications, and their optimizations have been focused on efficiency of those communication algorithms. However, point-to-point communications are not the optimal choice for modern computing clusters of SMPs due to their two-level communication structure. In recent years, a few research efforts have investigated efficient collective communications for SMP clusters. This dissertation is focused on platform-independent algorithms and implementations in this area. There are two main approaches to implementing efficient collective communications for clusters of SMPs: using shared memory operations for intra-node communications, and overlapping inter-node/intra-node communications. The former fully utilizes the hardware based shared memory of an SMP, and the latter takes advantage of the inherent hierarchy of the communications within a cluster of SMPs. Previous studies focused on clusters of SMP from certain vendors. However, the previously proposed methods are not portable to other systems. Because the performance optimization issue is very complicated and the developing process is very time consuming, it is highly desired to have self-tuning, platform-independent implementations. As proven in this dissertation, such an implementation can significantly out-perform the other point-to-point based portable implementations and some platform-specific implementations. The dissertation describes in detail the architecture of the platform-independent implementation. There are four system components: shared memory-based collective communications, overlapping mechanisms for inter-node and intra-node communications, a prediction-based tuning module and a micro-benchmark based tuning module. Each component is carefully designed with the goal of automatic tuning in mind.

  5. Creativity in clinical communication: from communication skills to skilled communication.

    Salmon, Peter; Young, Bridget

    2011-03-01

    Medical Education 2011: 45: 217-226 Objectives  The view that training in communication skills produces skilled communication is sometimes criticised by those who argue that communication is individual and intuitive. We therefore examine the validity of the concept of communication as a skill and identify alternative principles to underpin future development of this field. Methods  We critically examine research evidence about the nature of clinical communication, and draw from theory and evidence concerning education and evaluation, particularly in creative disciplines. Results  Skilled communication cannot be fully described using the concept of communication skills. Attempts to do so risk constraining and distorting pedagogical development in communication. Current education practice often masks the difficulties with the concept by introducing subjectivity into the definition and assessment of skills. As all clinical situations differ to some extent, clinical communication is inherently creative. Because it is rarely possible to attribute specific effects to specific elements of communication, communication needs to be taught and evaluated holistically. Conclusions  For communication teaching to be pedagogically and clinically valid in supporting the inherent creativity of clinical communication, it will need to draw from education theory and practice that have been developed in explicitly creative disciplines.

    Multimedia processing in battery powered mobile communication devices is pushing their computing power requirements to the level of desktop computers. At the same time the energy dissipation limit stays at 3W that is the practical maximum to prevent the devices from becoming too hot to handle. In addition, several hours of active usage time should be provided on battery power. During the last ten years the active usage times of mobile communication devices have remained essentially the same regardless of big energy efficiency improvements at silicon level. The reasons can be traced to the design paradigms that are not explicitly targeted to creating energy efficient systems, but to facilitate implementing complex software solutions by large teams. Consequently, the hardware and software architectures, including the operating system principles, are the same for both mainframe computer system and current mobile phones. In this paper, we consider the observed developments against the needs of video processing in mobile communication devices and consider means of implementing energy efficient video codecs both in hardware and software. Although inflexible, monolithic video acceleration hardware is an attractive solution, while software based codecs are becoming increasingly difficult to implement in an energy efficient manner due to increasing system complexity. Approaches that combine both the flexibility of software and energy efficiency of hardware remain to be seen.

This model captures many use cases effectively; however, it also limits communication concurrency and interoperability between MPI and programming models that utilize threads. Our paper describes the MPI endpoints extension, which relaxes the longstanding one-to-one relationship between MPI processes and ranks. Using endpoints, an MPI implementation can map separate communication contexts to threads, allowing them to drive communication independently. Also, endpoints enable threads to be addressable in MPI operations, enhancing interoperability between MPI and other programming models.

    The Communication Systems Simulation Laboratory (CSSL) at the NASA Johnson Space Center is tasked to perform spacecraft and ground network communication system simulations, design validation, and performance verification. The CSSL has developed simulation tools that model spacecraft communication systems and the space and ground environment in which the tools operate. In this paper, a spacecraft communication system with multiple arrays is simulated. Multiple array combined technique is used to increase the radio frequency coverage and data rate performance. The technique is to achieve phase coherence among the phased arrays to combine the signals at the targeting receiver constructively. There are many technical challenges in spacecraft integration with a high transmit power communication system. The array combining technique can improve the communication system data rate and coverage performances without increasing the system transmit power requirements. Example simulation results indicate significant performance improvement can be achieved with phase coherence implementation.

    Only eight years after the launc of Sputnik-1 by the Soviet Union, the first commercial satellite, 'Early Bird', entered service. In just twelve years commercial satellite service extended around the earth and became profitable. The reasons for the successful development of the communications satellite services in a comparatively short time are considered. These reasons are related to the presence of three ingredients, taking into account technology to create the system, communications requirements to form a market, and a management structure to implement the system. The formation of the concept of using earth orbiting satellites for telecommunications is discussed. It is pointed out that the years from 1958 to 1964 were the true 'experimental years' for satellite communications. The rapid development of technology during this crucial period is described, giving attention to passive satellites, active systems, and development satellites.

    The first practical application of quantum physics examined in this book is quantum cryptography. Quantum cryptography is a relatively recent invention (it dates back from the mid 1980s) but I chose it because it allows me to illustrate the fundamental principles with a minimum number of intermediate steps. I shall begin with a short summary of classical cryptography, reviewing briefly the two systems which are currently used today: the secret key system and the public key system. Quantum cryptography is not a new method for dissimulating the meaning of a message, but it allows one to be certain that no spy has accessed it. There exist many quantum cryptography protocols and various experimental devices have been proposed for implementing them. The simplest device is based on polarization, a concept which will be introduced first in the case of of light polarization, and then in that of photon polarization. The use of photon polarization gives the simplest implementation of the protocol proposed in 1984 by Bennett and Brassard, which is known by the acronym formed with their initials, the BB84 protocol.

    "Nothing in science has any value to society if it is not communicated." So goes the 1952 quote from Anne Roe, the noted twentieth century American psychologist and writer. She went on to say that "scientists are beginning to learn their social obligations", and now over 60 years later there is certainly evidence to support her assertions. As scientists, by communicating our research to the general public we not only better inform the tax payer where their money is being spent, but are also able to help put into context the topical environmental challenges and issues that society faces, as well as inspiring a whole new generation of future scientists. This process of communication is very much a two-way street; by presenting our work to people outside of our usual spheres of contemporaries, we expose ourselves to alternative thoughts and insights that can inspire us, as scientists, to take another look at our research from angles that we had never before considered. This work presents the results and experiences from a number of public engagement and outreach activities across the UK, in which geoscientists engaged and interacted with members of the general public. These include the design and implementation of Raspberry Pi based outreach activities for several hundred high school students; the process of running a successful podcast (http://thebarometer.podbean.com); hosting and participating in science events for thousands of members of the general public (e.g. http://www.manchestersciencefestival.com and http://sse.royalsociety.org/2013); and creating a citizen science activity that involved primary school children from across the UK. In communicating their research it is imperative that scientists interact with their audience in an effective and engaging manner, whether in an international conference, a classroom, or indeed down the pub. This work also presents a discussion of how these skills can be developed at an early stage in the careers of a research

    2001-04-01

    The distribution of entangled states between distant locations will be essential for the future large-scale realization of quantum communication schemes such as quantum cryptography and quantum teleportation. Because of unavoidable noise in the quantum communication channel, the entanglement between two particles is more and more degraded the further they propagate. Entanglement purification is thus essential to distil highly entangled states from less entangled ones. Existing general purification protocols are based on the quantum controlled-NOT (CNOT) or similar quantum logic operations, which are very difficult to implement experimentally. Present realizations of CNOT gates are much too imperfect to be useful for long-distance quantum communication. Here we present a scheme for the entanglement purification of general mixed entangled states, which achieves 50 per cent of the success probability of schemes based on the CNOT operation, but requires only simple linear optical elements. Because the perfection of such elements is very high, the local operations necessary for purification can be performed with the required precision. Our procedure is within the reach of current technology, and should significantly simplify the implementation of long-distance quantum communication.

    Hybrid metrology (HM) is the practice of combining measurements from multiple toolset types in order to enable or improve metrology for advanced structures. HM is implemented in two phases: Phase-1 includes readiness of the infrastructure to transfer processed data from the first toolset to the second. Phase-2 infrastructure allows simultaneous transfer and optimization of raw data between toolsets such as spectra, images, traces - co-optimization. We discuss the extension of Phase-1 to include direct high-bandwidth communication between toolsets using a hybrid server, enabling seamless fab deployment and further laying the groundwork for Phase-2 high volume manufacturing (HVM) implementation. An example of the communication protocol shows the information that can be used by the hybrid server, differentiating its capabilities from that of a host-based approach. We demonstrate qualification and production implementation of the hybrid server approach using CD-SEM and OCD toolsets for complex 20nm and 14nm applications. Finally we discuss the roadmap for Phase-2 HM implementation through use of the hybrid server.

The second column focused on information and resources to master basic computer competencies described by the TIGER initiative (Technology Informatics Guiding Education Reform) as learning about computers, computer networks, and the transfer of data.1 This column will provide additional information related to basic computer competencies, focusing on communication and collaboration technologies. Computers and the Internet have transformed the way we communicate and collaborate. Electronic communication is the ability to exchange information through the use of computer equipment and software.2 Broadly defined, any technology that facilitates linking one or more individuals together is a collaborative tool. Collaboration using technology encompasses an extensive range of applications that enable groups of individuals to work together including e-mail, instant messaging (IM ), and several web applications collectively referred to as Web 2.0 technologies. The term Web 2.0 refers to web applications where users interact and collaborate with each other in a collective exchange of ideas generating content in a virtual community. Examples of Web 2.0 technologies include social networking sites, blogs, wikis, video sharing sites, and mashups. Many organizations are developing collaborative strategies and tools for employees to connect and interact using web-based social media technologies.3. PMID:22397797

    2011-01-01

    This software is an implementation of the Licklider Transmission Protocol (LTP), a communications protocol intended to support the Bundle Protocol in Delay-Tolerant Network (DTN) operations. LTP is designed to provide retransmission-based reliability over links characterized by extremely long message round-trip times and/or frequent interruptions in connectivity. Communication in interplanetary space is the most prominent example of this sort of environment, and LTP is principally aimed at supporting long-haul reliable transmission over deep-space RF links. Like any reliable transport service employing ARQ (Automatic Repeat re-Quests), LTP is stateful. In order to assure the reception of a block of data it has sent, LTP must retain for possible retransmission all portions of that block which might not have been received yet. In order to do so, it must keep track of which portions of the block are known to have been received so far, and which are not, together with any additional information needed for purposes of retransmitting part, or all, of the block. Long round-trip times mean substantial delay between the transmission of a block of data and the reception of an acknowledgement from the block s destination, signaling arrival of the block. If LTP postponed transmission of additional blocks of data until it received acknowledgement of the arrival of all prior blocks, valuable opportunities to use what little deep space transmission bandwidth is available would be forever lost. For this reason, LTP is based in part on a notion of massive state retention. Any number of requested transmission conversations (sessions) may be concurrently in flight at various displacements along the link between two LTP engines, and the LTP engines must necessarily retain transmission status and retransmission resources for all of them. Moreover, if any of the data of a given block are lost en route, it will be necessary to retain the state of that transmission during an additional

    Quantum communication (QC), namely, the faithful transmission of generic quantum states, is a key ingredient of quantum information science. Here we demonstrate QC with polarization encoding from space to ground by exploiting satellite corner cube retroreflectors as quantum transmitters in orbit and the Matera Laser Ranging Observatory of the Italian Space Agency in Matera, Italy, as a quantum receiver. The quantum bit error ratio (QBER) has been kept steadily low to a level suitable for several quantum information protocols, as the violation of Bell inequalities or quantum key distribution (QKD). Indeed, by taking data from different satellites, we demonstrate an average value of QBER =4.6 % for a total link duration of 85 s. The mean photon number per pulse μsat leaving the satellites was estimated to be of the order of one. In addition, we propose a fully operational satellite QKD system by exploiting our communication scheme with orbiting retroreflectors equipped with a modulator, a very compact payload. Our scheme paves the way toward the implementation of a QC worldwide network leveraging existing receivers.

    The ORBCOMM system is designed to provide low-cost, two-way data communications for mobile and remote users. The communications system is ideally configured for low data rate applications where communicating devices are geographically dispersed and two-way communications through terrestrial means is cumbersome and not cost effective. The remote terminals use VHF frequencies which allow for the use of very small, low-cost terminals. ORBCOMM has entered into joint development agreements with several large manufacturers of both consumer and industrial electronics to design and build the remote terminals. Based on prototype work, the estimated retail cost of these units will range from $50 to $400 depending on the complexity of the design. Starting in the fall of 1993, ORBCOMM will begin service with a demonstration network consisting of two operating satellites. By the end of 1994, a full operating network of 26 satellites, four Gateway Earth Stations, and a Network Control Center will be in place. The full constellation will provide full coverage of the entire world with greater than 94 percent communications availability for the continental U.S. This paper describes the ORBCOMM system, the technology used in its implementation, and its applications.

    Quantum communication systems harness modern physics through state-of-the-art optical engineering to provide revolutionary capabilities. An important concern for quantum communication engineering is designing and prototyping these systems to prototype proposed capabilities. We apply the paradigm of software-defined communica- tion for engineering quantum communication systems to facilitate rapid prototyping and prototype comparisons. We detail how to decompose quantum communication terminals into functional layers defining hardware, software, and middleware concerns, and we describe how each layer behaves. Using the super-dense coding protocol as a test case, we describe implementations of both the transmitter and receiver, and we present results from numerical simulations of the behavior. We find that while the theoretical benefits of super dense coding are maintained, there is a classical overhead associated with the full implementation.

    2011-01-01

    The Midwest Geological Sequestration Consortium, Schlumberger Carbon Services, and Archer Daniels Midland has implemented a comprehensive communications plan at the Illinois Basin - Decatur Project (IBDP), a one million metric tonne Carbon Capture and Storage project in Decatur, IL, USA funded by the U.S. Department of Energy's National Energy Technology Laboratory. The IBDP Communication Plan includes consortium information, funding and disclaimer citations, description of target audiences, media communications guidelines, paper and presentations guidelines, site visit information, crisis communication, on-site photography regulations, and other components. The creation, development, and implementation processes for the IBDP Communication Plan (the Plan) are shared in this paper. New communications challenges, such as how to address add-on research requests, data sharing and management, scope increase, and contract agreements have arisen since the Plan was completed in January 2009, resulting in development of new policies and procedures by project management. Integrating communications planning, risk assessment, and project management ensured that consistent, factual information was developed and incorporated into project planning, and constitutes the basis of public communications. Successful integration has allowed the IBDP to benefit from early identification and mitigation of the potential project risks, which allows more time to effectively deal with unknown and unidentified risks that may arise. Project risks and risks associated with public perception can be managed through careful planning and integration of communication strategies into project management and risk mitigation. ?? 2011 Published by Elsevier Ltd.

    1998-01-01

    In this paper we report on features added to a parallel debugger to simplify the debugging of parallel message passing programs. These features include replay, setting consistent breakpoints based on interprocess event causality, a parallel undo operation, and communication supervision. These features all use trace information collected during the execution of the program being debugged. We used a number of different instrumentation techniques to collect traces. We also implemented trace displays using two different trace visualization systems. The implementation was tested on an SGI Power Challenge cluster and a network of SGI workstations.

    1987-06-01

    Communication support for health and family planning programs is receiving renewed attention. The johns Hopkins University (JHU) Population Communication Services (PCS) project was established in 1982 to respond to the increasing need for communication expertise, to provide a responsive source for advice, and to develop implement the new directions that are necessary to make family planning communication programs more effective. The project extends a range of services to government programs, private family planning associations, and to media that want to improve the content or coverage of family planning communication, JHU/PCS emphasizes the close links between good communication and good management and the need for managers at all levels, from the Minister of Health to the supervisor of grass-roots field workers, to understand the components of a communication program for the 1980s. Principles underlying the project's work include: communication as process rather than product, the audience as participant, linking mass media and interpersonal communication, coordination with and among agencies, training that is specific and relevant, IEC as institution building, use of the private sector, an attempt to recover some of the costs of IEC work, and ongoing evaluation of program activities. IEC activities can be strengthened considerably b a knowledgeable commitment at the top of the decision-making process; constant feedback from intended audiences; and interactions among service delivery personnel, influential community members, and the media. In turn, strong IEC activities can substantially strengthen existing family planning programs. PMID:12341766

    There are many APIs for connecting and exchanging data between network peers. Each interface varies wildly based on metrics including performance, portability, and complexity. Specifically, many interfaces make design or implementation choices emphasizing some of the more desirable metrics (e.g., performance) while sacrificing others (e.g., portability). As a direct result, software developers building large, network-based applications are forced to choose a specific network API based on a complex, multi-dimensional set of criteria. Such trade-offs inevitably result in an interface that fails to deliver some desirable features. In this paper, we introduce a novel interface that both supports many features that have become standard (or otherwise generally expected) in other communication interfaces, and strives to export a small, yet powerful, interface. This new interface draws upon years of experience from network-oriented software development best practices to systems-level implementations. The goal is to create a relatively simple, high-level communication interface with low barriers to adoption while still providing important features such as scalability, resiliency, and performance. The result is the Common Communications Interface (CCI): an intuitive API that is portable, efficient, scalable, and robust to meet the needs of network-intensive applications common in HPC and cloud computing.

  13. Promoting Strong Written Communication Skills

    2015-12-01

    The reason that an improvement in the quality of technical writing is still needed in the classroom is due to the fact that universities are facing challenging problems not only on the technological front but also on the socio-economic front. The universities are actively responding to the changes that are taking place in the global consumer marketplace. Obviously, there are numerous benefits of promoting strong written communication skills. They can be summarized into the following six categories. First, and perhaps the most important: The University achieves learner satisfaction. The learner has documented verbally, that the necessary knowledge has been successfully acquired. This results in learner loyalty that in turn will attract more qualified learners.Second, quality communication lowers the cost per pupil, consequently resulting in increased productivity backed by a stronger economic structure and forecast. Third, quality communications help to improve the cash flow and cash reserves of the university. Fourth, having high quality communication enables the university to justify the need for high costs of tuition and fees. Fifth, better quality in written communication skills result in attracting top-quality learners. This will lead to happier and satisfied learners, not to mention greater prosperity for the university as a whole. Sixth, quality written communication skills result in reduced complaints, thus meaning fewer hours spent on answering or correcting the situation. The University faculty and staff are thus able to devote more time on scholarly activities, meaningful research and productive community service. References Boyer, Ernest L. (1990).

    Personal Communications Services (PCS) may be the key ingredient for vastly improved military communications capabilities at the turn of the century. The Federal Communications Commission (FCC) defines PCS as a family of mobile or portable radio communications services which could provide services to individuals and businesses and be integrated with a variety of competing networks ... the primary focus of PCS will be to meet communications requirements of people on the move. Today's generation of Theater Deployable Communications, which provides joint tactical communications to deployed forces, is the Tri-Service Tactical Communications (TRI-TAC) system. A description of TRITAC's family of equipment, network topology, typical employment, and critical limitations is presented in this thesis. Five commercial Mobile Satellite Services (MSS) are described as viable candidates for augmenting existing communications systems. Cellular design principles such as frequency reuse, cell splitting, channel access methods, and propagation factors are also addressed. Finally, a framework for comparison of the candidate MSS systems is proposed as a baseline for further studies into the most beneficial implementation of PCS into theater deployable communications systems for the future.

    NASA Astrophysics Data System (ADS)

    Hughes, Richard

    2014-03-01

    Single-photon quantum communications (QC) offers ``future-proof'' cryptographic security rooted in the laws of physics. Today's quantum-secured communications cannot be compromised by unanticipated future technological advances. But to date, QC has only existed in point-to-point instantiations that have limited ability to address the cyber security challenges of our increasingly networked world. In my talk I will describe a fundamentally new paradigm of network-centric quantum communications (NQC) that leverages the network to bring scalable, QC-based security to user groups that may have no direct user-to-user QC connectivity. With QC links only between each of N users and a trusted network node, NQC brings quantum security to N2 user pairs, and to multi-user groups. I will describe a novel integrated photonics quantum smartcard (``QKarD'') and its operation in a multi-node NQC test bed. The QKarDs are used to implement the quantum cryptographic protocols of quantum identification, quantum key distribution and quantum secret splitting. I will explain how these cryptographic primitives are used to provide key management for encryption, authentication, and non-repudiation for user-to-user communications. My talk will conclude with a description of a recent demonstration that QC can meet both the security and quality-of-service (latency) requirements for electric grid control commands and data. These requirements cannot be met simultaneously with present-day cryptography.

    2004-07-01

    The future model of the US Army's Future Combat Systems (FCS) and the Future Force reflects a combat force that utilizes lighter armor protection than the current standard. Survival on the future battlefield will be increased by the use of advanced situational awareness provided by unattended tactical and urban sensors that detect, identify, and track enemy targets and threats. Successful implementation of these critical sensor fields requires the development of advanced sensors, sensor and data-fusion processors, and a specialized communications network. To ensure warfighter and asset survivability, the communications must be capable of near real-time dissemination of the sensor data using robust, secure, stealthy, and jam resistant links so that the proper and decisive action can be taken. Communications will be provided to a wide-array of mission-specific sensors that are capable of processing data from acoustic, magnetic, seismic, and/or Chemical, Biological, Radiological, and Nuclear (CBRN) sensors. Other, more powerful, sensor node configurations will be capable of fusing sensor data and intelligently collect and process data images from infrared or visual imaging cameras. The radio waveform and networking protocols being developed under the Soldier Level Integrated Communications Environment (SLICE) Soldier Radio Waveform (SRW) and the Networked Sensors for the Future Force Advanced Technology Demonstration are part of an effort to develop a common waveform family which will operate across multiple tactical domains including dismounted soldiers, ground sensor, munitions, missiles and robotics. These waveform technologies will ultimately be transitioned to the JTRS library, specifically the Cluster 5 requirement.

    The LSST middleware design is based on a set of software abstractions; which provide standard interfaces for common communications services. The observatory requires communication between many subsystems, and comprehensive archiving of subsystem status data. Control commands as well as health and status data from across the observatory must be stored to support both the science data analysis, and trending analysis for the early detection of hardware anomalies. The Service Abstraction Layer (SAL) is implemented using open source packages that implement open standards of DDS (Data DistributionService) for data communication and SQL for storage. Designs for the automatic generation of code, documentation, and subsystem simulation, are being developed. Abstractions for the Telemetry datastreams, each with customized data structures, Command/Response, and the Logging and Alert messages are described.

    Medical leadership requires specific communication skills in order to meet professional demands. Communicative behaviour is usually highly automated and not necessarily conscious. Managerial communication competes against elaborated but not role-specific behaviour patterns, especially in critical situations. Accordingly, competent medical leadership requires the awareness of individual communication habits as well as the knowledge and ability to use conversation techniques suitable for a specific situational context. The training of leadership-related communication techniques requires the de-automation of existing skills and a problem-oriented construction and re-automation of new communication techniques.

    While cities cover only 2% of the Earth's surface, over 50% of the world's people live in urban environments. Precisely because of their population density, cities can play a large role in reducing or exacerbating the global impact of climate change. The actions of cities could hold the key to slowing down climate change. Urban dwellers are becoming more aware of the need to reduce their carbon usage and to implement adaptation strategies. However, messaging around these strategies has not been comprehensive and adaptation to climate change requires local knowledge, capacity and a high level of coordination. Unless urban populations understand climate change and its impacts it is unlikely that cities will be able to successfully implement policies that reduce anthropogenic climate change. Informal and formal educational institutions in urban environments can serve as catalysts when partnering with climate scientists, educational research groups, and public policy makers to disseminate information about climate change and its impacts on urban audiences. The Climate and Urban Systems Partnership (CUSP) is an interdisciplinary network designed to assess and meet the needs and challenges of educating urban audiences about climate change. CUSP brings together organizations in Philadelphia, Pittsburgh, Queens, NY and Washington, DC to forge links with informal and formal education partners, city government, and policy makers. Together this network will create and disseminate learner-focused climate education programs and resources for urban audiences that, while distinct, are thematically and temporally coordinated, resulting in the communication of clear and consistent information and learning experiences about climate science to a wide public audience. Working at a community level CUSP will bring coordinated programming directly into neighborhoods presenting the issues of global climate change in a highly local context.

  16. Advanced Communications Technology: Mobile Communications Requirements Report

    NASA Astrophysics Data System (ADS)

    1998-05-01

    The Coast Guard's mobile communications requirements will outstrip existing system capabilities, available capacity, and affordability by the late 1990s. This will require changes in the mix of mobile communications equipment and services used by operational units. New commercial mobile satellite services are available now, with many others arriving on the market between 1998 and 2003. These new services present unique opportunities to satisfy mission requirements, reduce investment in communications infrastructure, and realize more costeffective communications services. The Coast Guard Research and Development Center (R&DC) has undertaken an effort to identify and evaluate current and emerging satellite services that may be used to satisfy Coast Guard mobile communications requirements. As part of this effort, Anteon Corporation has been tasked by R&DC to collect the mobile communications functional requirements that have been identified by program managers. Anteon analysts have reviewed the Government Furnished Information (GFI) and researched other related documentation to identify and collect the requirements that may be used to describe the needed operating environment. Anteon analysts assessed the functional requirements to develop system requirements that describe the features that a communications system must provide to support the functional requirements. This report presents the current and projected Coast Guard mobile communications system requirements.

  18. Visible Light Wireless Communication for Audio Signals

    NASA Astrophysics Data System (ADS)

    Vibin, A. M.; Prince, Shanthi

    2011-10-01

    In the current century there is an increased demand for broad band wireless access for satisfying different customer needs. These applications requires large amount of frequency resources for its efficient implementation. Radio Frequency techniques, which dominate the current wireless technology, have the limitation of available frequency spectrum that can be used. Researchers identified Optical Wireless Communication as a potential candidate for solving this problem. Studies shows that white light can also be used as a carrier for wireless communication and this area is generally known as Visible Light Communication. The provision of voice data and visual communications to users by using optical wireless has become a key area of research and product development. This paper discusses a novel method for transmission of voice in real time so that the system can be used for both communication and illumination simultaneously. A prototype of the system is implemented successfully and performance analyses are carried out based on the experimental results. SNR and BER calculations for the designed system is done theoretically and simulated. The developed system is having the advantages of very high band width, no interference with adjacent rooms as walls are opaque, no license is required as it doesn't cause electromagnetic interference and communication simultaneously with illumination.

  19. Generalized hypercube structures and hyperswitch communication network

    NASA Technical Reports Server (NTRS)

    Young, Steven D.

    1992-01-01

    This paper discusses an ongoing study that uses a recent development in communication control technology to implement hybrid hypercube structures. These architectures are similar to binary hypercubes, but they also provide added connectivity between the processors. This added connectivity increases communication reliability while decreasing the latency of interprocessor message passing. Because these factors directly determine the speed that can be obtained by multiprocessor systems, these architectures are attractive for applications such as remote exploration and experimentation, where high performance and ultrareliability are required. This paper describes and enumerates these architectures and discusses how they can be implemented with a modified version of the hyperswitch communication network (HCN). The HCN is analyzed because it has three attractive features that enable these architectures to be effective: speed, fault tolerance, and the ability to pass multiple messages simultaneously through the same hyperswitch controller.

  20. Adaptive Power Control for Space Communications

    NASA Technical Reports Server (NTRS)

    Thompson, Willie L., II; Israel, David J.

    2008-01-01

    This paper investigates the implementation of power control techniques for crosslinks communications during a rendezvous scenario of the Crew Exploration Vehicle (CEV) and the Lunar Surface Access Module (LSAM). During the rendezvous, NASA requires that the CEV supports two communication links: space-to-ground and crosslink simultaneously. The crosslink will generate excess interference to the space-to-ground link as the distances between the two vehicles decreases, if the output power is fixed and optimized for the worst-case link analysis at the maximum distance range. As a result, power control is required to maintain the optimal power level for the crosslink without interfering with the space-to-ground link. A proof-of-concept will be described and implemented with Goddard Space Flight Center (GSFC) Communications, Standard, and Technology Lab (CSTL).

  1. Communicators' perspective on snow avalanche risk communication

    NASA Astrophysics Data System (ADS)

    Charriere, M. K. M.; Bogaard, T.; Mostert, E.

    2014-12-01

    Among all the natural hazards, snow avalanches are the only ones for which a public danger scale is globally used. It consists of 5 levels of danger displayed with a given number and colour and for each of them, behavioural advices are provided. Even though this is standardized in most of the countries affected by this natural hazard, the tools (usually websites or smartphone applications) with which the information is disseminated to the general pubic differs, particularly in terms of target audience and level of details. This study aims at gathering the perspectives of several communicators that are responsible for these communication practices. The survey was created to assess how and why choices were made in the design process of the communication tools and to determine how their effectiveness is evaluated. Along with a review of existing avalanche risk communication tools, this study provides guidelines for communication and the evaluation of its effectiveness.

  13. Wireless Communications in Reverberant Environments

    NASA Astrophysics Data System (ADS)

    Measel, Ryan Thomas

    Implementation of WLANs in reverberant environments, such as industrial facilities, naval vessels, aircraft, and spacecraft, has proven challenging, because rich electromagnetic scattering can degrade link quality through multipath interference. As a result, the adoption of Wireless LANs in these environments has been slow. Previous studies concerning reverberant environments have focused on characterizing electromagnetic properties for the purpose of electromagnetic compatibility testing. Little attention has been given to the performance of wireless communications. In this effort, the effect of electromagnetic reverberance on wireless communications is investigated in order to assess the feasibility of WLAN deployment. Work centered around two experimental measurement campaigns. The first campaign was performed in coupled reverberation chambers. The reverberation chambers provided a controllable environment which was configured to emulate the reverberance of below-deck spaces on a naval vessel. The process for quantifying and configuring the electromagnetic properties of a reverberation chamber is presented. The second campaign was performed on a naval vessel. Experimentation was conducted in a variety of locations on the ship. Locations were selected to represent a wide range of practical environments. Across both campaigns, several environment and node parameters were evaluated: level of reverberance, cavity coupling (effective aperture size), and LOS versus NLOS links. Additionally, advanced physical layer schemes and reconfigurable antennas are presented as methods to improve performance and mitigate multipath interference. To perform this work, a measurement platform and testing protocol were developed for systematic characterization of wireless communications in reverberant environments. The primary contributions of this work are empirical characterization of wireless communications in reverberant environments, approaches to improving the performance of

  14. Protocols for Scholarly Communication

    NASA Astrophysics Data System (ADS)

    Pepe, A.; Yeomans, J.

    2007-10-01

    CERN, the European Organization for Nuclear Research, has operated an institutional preprint repository for more than 10 years. The repository contains over 850,000 records of which more than 450,000 are full-text OA preprints, mostly in the field of particle physics, and it is integrated with the library's holdings of books, conference proceedings, journals and other grey literature. In order to encourage effective propagation and open access to scholarly material, CERN is implementing a range of innovative library services into its document repository: automatic keywording, reference extraction, collaborative management tools and bibliometric tools. Some of these services, such as user reviewing and automatic metadata extraction, could make up an interesting testbed for future publishing solutions and certainly provide an exciting environment for e-science possibilities. The future protocol for scientific communication should guide authors naturally towards OA publication, and CERN wants to help reach a full open access publishing environment for the particle physics community and related sciences in the next few years.

  3. Adaptive Suppression of Noise in Voice Communications

    NASA Technical Reports Server (NTRS)

    Kozel, David; DeVault, James A.; Birr, Richard B.

    2003-01-01

    A subsystem for the adaptive suppression of noise in a voice communication system effects a high level of reduction of noise that enters the system through microphones. The subsystem includes a digital signal processor (DSP) plus circuitry that implements voice-recognition and spectral- manipulation techniques. The development of the adaptive noise-suppression subsystem was prompted by the following considerations: During processing of the space shuttle at Kennedy Space Center, voice communications among test team members have been significantly impaired in several instances because some test participants have had to communicate from locations with high ambient noise levels. Ear protection for the personnel involved is commercially available and is used in such situations. However, commercially available noise-canceling microphones do not provide sufficient reduction of noise that enters through microphones and thus becomes transmitted on outbound communication links.

    1995-01-01

    This reviews the efforts of the Centers for Disease Control and Prevention to integrate effective health communication into its programs that are designed to change behaviors. Although the 10-step framework for developing and implementing the Centers' health communication programs is both practical and comprehensive, it is suggested that a reversal of steps 2 and 3 is a more logical sequence, is more consistent with the literature and, more importantly, could avoid misapplications of the framework by less experienced practitioners. Comment is also made on the dynamic nature of health communication planning and development, a point not made explicit in the Centers' framework. PMID:7631001

  6. Intrication temporelle et communication quantique

    NASA Astrophysics Data System (ADS)

    Bussieres, Felix

    Quantum communication is the art of transferring a quantum state from one place to another and the study of tasks that can be accomplished with it. This thesis is devoted to the development of tools and tasks for quantum communication in a real-world setting. These were implemented using an underground optical fibre link deployed in an urban environment. The technological and theoretical innovations presented here broaden the range of applications of time-bin entanglement through new methods of manipulating time-bin qubits, a novel model for characterizing sources of photon pairs, new ways of testing non-locality and the design and the first implementation of a new loss-tolerant quantum coin-flipping protocol. Manipulating time-bin qubits. A single photon is an excellent vehicle in which a qubit, the fundamental unit of quantum information, can be encoded. In particular, the time-bin encoding of photonic qubits is well suited for optical fibre transmission. Before this thesis, the applications of quantum communication based on the time-bin encoding were limited due to the lack of methods to implement arbitrary operations and measurements. We have removed this restriction by proposing the first methods to realize arbitrary deterministic operations on time-bin qubits as well as single qubit measurements in an arbitrary basis. We applied these propositions to the specific case of optical measurement-based quantum computing and showed how to implement the feedforward operations, which are essential to this model. This therefore opens new possibilities for creating an optical quantum computer, but also for other quantum communication tasks. Characterizing sources of photon pairs. Experimental quantum communication requires the creation of single photons and entangled photons. These two ingredients can be obtained from a source of photon pairs based on non-linear spontaneous processes. Several tasks in quantum communication require a precise knowledge of the properties

  5. Physician-patient communication: a lost art?

    PubMed

    Frymoyer, John W; Frymoyer, Nan P

    2002-01-01

    In the face of rapid advances in technology, there has been a progressive deterioration of effective physician-patient communication. The American Academy of Orthopaedic Surgeons has identified that patients rate the orthopaedic profession as high in technical and low in communication skills. Poor communication, especially patient-interviewing skills, has been identified in medical students as well as in practicing physicians. Effective communication is associated with improved patient and physician satisfaction, better patient compliance, improved health outcomes, better-informed medical decisions, and reduced malpractice suits, and it likely contributes to reduced costs of care. Recognition of the importance of communication has influenced medical schools to revise curricula and to teach communication skills in residency training and continuing medical education programs. National certifying examinations also are being designed to incorporate these skills. Although written material is useful in increasing awareness of the importance of good physician-patient communication, behavioral change is more likely to occur in a workshop environment. The American Academy of Orthopaedic Surgeons is taking leadership in designing and implementing such an approach for its membership. PMID:11929204

    Google the question, “How is the Internet changing the way we communicate?,” and you will find no shortage of opinions, or fears, about the Internet altering the way we communicate. Although the Internet is not necessarily making communication briefer (neither is the Internet making communication less formal), the Internet is manifesting our preference for writing over speaking. I propose that our preference for communicating through Internet-based text derives from a fundamental feature of writing: In contrast to speech, which is most often synchronous, text is most often asynchronous.

    Good communication between nurses and patients is essential for the successful outcome of individualized nursing care of each patient. To achieve this, however, nurses must understand and help their patients, demonstrating courtesy, kindness and sincerity. Also they should devote time to the patient to communicate with the necessary confidentiality, and must not forget that this communication includes persons who surround the sick person, which is why the language of communication should be understood by all those involved in it. Good communication also is not only based on the physical abilities of nurses, but also on education and experience. PMID:24757408

    2009-09-01

    As part of a general review of Superconductor Science and Technology, we have been examining the scope for Rapid Communications (RAPs). We recognize these articles make up an important part of the journal representing the latest state-of-the-art research in superconductivity. To reflect this, we have devised a new scope for this article type: 'Rapid Communications. The journal offers open access to outstanding short articles (no longer than 5 journal pages or 4500 words including figures) reporting new and timely developments in superconductivity and its applications. These articles should report very substantial new advances in superconductivity to the readers of Superconductor Science and Technology, but are not expected to meet any requirement of 'general interest'. RAPs will be processed quickly (average receipt to online publication for RAPs is around 60 days) and are permanently free to read in the electronic journal. Authors submitting a RAP should provide reasons why the work is urgent and requires rapid publication. Each RAP will be assessed for suitability by our Reviews and Rapid Communications Editor before full peer review takes place.' The essential points are: They should report very substantial new advances in superconductivity and its application; They must be no longer than 5 journal pages long (approx. 4500 words); Average publication time for a Rapid Communication is 60 days; They are free to read. As mentioned in the previous publisher's announcement (2009 Supercond. Sci. Technol. 22 010101), each submitted Rapid Communication must come with a letter justifying why it should be prioritized over regular papers and will be pre-assessed by our Reviews and Rapid Communications Editor. In addition, we will work with the authors of any Rapid Communication to promote and raise the visibility of the work presented in it. We will be making further changes to the journal in the near future and we write to you accordingly. Thank you for your kind

  13. Communications interface for wireless communications headset

    NASA Technical Reports Server (NTRS)

    Seibert, Marc A. (Inventor); Culotta, Jr., Anthony Joseph (Inventor)

    2004-01-01

    A universal interface adapter circuit interfaces, for example, a wireless communications headset with any type of communications system, including those that require push-to-talk (PTT) signaling. The interface adapter is comprised of several main components, including an RF signaling receiver, a microcontroller and associated circuitry for decoding and processing the received signals, and programmable impedance matching and line interfacing circuitry for interfacing a wireless communications headset system base to a communications system. A signaling transmitter, which is preferably portable (e.g., handheld), is employed by the wireless headset user to send signals to the signaling receiver. In an embodiment of the invention directed specifically to push-to-talk (PTT) signaling, the wireless headset user presses a button on the signaling transmitter when they wish to speak. This sends a signal to the microcontroller which decodes the signal and recognizes the signal as being a PTT request. In response, the microcontroller generates a control signal that closes a switch to complete a voice connection between the headset system base and the communications system so that the user can communicate with the communications system. With this arrangement, the wireless headset can be interfaced to any communications system that requires PTT signaling, without modification of the headset device. In addition, the interface adapter can also be configured to respond to or deliver any other types of signals, such as dual-tone-multiple-frequency (DTMF) tones, and on/off hook signals. The present invention is also scalable, and permits multiple wireless users to operate independently in the same environment through use of a plurality of the interface adapters.

    1. Support of key decision makers is critical to the successful implementation of a corporate wellness program. Therefore, the program implementation plan must be communicated in a format and language readily understood by business people. 2. A business approach to corporate wellness program planning provides a standardized way to communicate the implementation plan. 3. A business approach incorporates the program planning components in a format that ranges from general to specific. This approach allows for flexibility and responsiveness to changes in program planning. 4. Components of the business approach are the executive summary, purpose, background, ground rules, approach, requirements, scope of work, schedule, and financials. PMID:7575791

  2. Communication Optimizations for a Wireless Distributed Prognostic Framework

    Saha, Sankalita; Saha, Bhaskar; Goebel, Kai

    2009-01-01

    Distributed architecture for prognostics is an essential step in prognostic research in order to enable feasible real-time system health management. Communication overhead is an important design problem for such systems. In this paper we focus on communication issues faced in the distributed implementation of an important class of algorithms for prognostics - particle filters. In spite of being computation and memory intensive, particle filters lend well to distributed implementation except for one significant step - resampling. We propose new resampling scheme called parameterized resampling that attempts to reduce communication between collaborating nodes in a distributed wireless sensor network. Analysis and comparison with relevant resampling schemes is also presented. A battery health management system is used as a target application. A new resampling scheme for distributed implementation of particle filters has been discussed in this paper. Analysis and comparison of this new scheme with existing resampling schemes in the context for minimizing communication overhead have also been discussed. Our proposed new resampling scheme performs significantly better compared to other schemes by attempting to reduce both the communication message length as well as number total communication messages exchanged while not compromising prediction accuracy and precision. Future work will explore the effects of the new resampling scheme in the overall computational performance of the whole system as well as full implementation of the new schemes on the Sun SPOT devices. Exploring different network architectures for efficient communication is an importance future research direction as well.

  5. Enhancing flood resilience through improved risk communications

    NASA Astrophysics Data System (ADS)

    O'Sullivan, J. J.; Bradford, R. A.; Bonaiuto, M.; De Dominicis, S.; Rotko, P.; Aaltonen, J.; Waylen, K.; Langan, S. J.

    2012-07-01

    A framework of guiding recommendations for effective pre-flood and flood warning communications derived from the URFlood project (2nd ERA-Net CRUE Research Funding Initiative) from extensive quantitative and qualitative research in Finland, Ireland, Italy and Scotland is presented. Eleven case studies in fluvial, pluvial, coastal, residual and "new" flood risk locations were undertaken. The recommendations were developed from questionnaire surveys by exploring statistical correlations of actions and understandings of individuals in flood risk situations to low, moderate and high resilience groupings. Groupings were based on a conceptual relationship of self-assessed levels of awareness, preparedness and worry. Focus groups and structured interviews were used to discuss barriers in flood communications, explore implementation of the recommendations and to rank the recommendations in order of perceived importance. Results indicate that the information deficit model for flood communications that relies on the provision of more and better information to mitigate risk in flood-prone areas is insufficient, and that the communications process is very much multi-dimensional. The recommendations are aimed at addressing this complexity and their careful implementation is likely to improve the penetration of flood communications. The recommendations are applicable to other risks and are transferrable to jurisdictions beyond the project countries.

  6. Communication elements supporting patient safety in psychiatric inpatient care.

    2015-06-01

    Communication is important for safe and quality health care. The study provides needed insight on the communication elements that support patient safety from the psychiatric care view. Fluent information transfer between the health care professionals and care units is important for care planning and maintaining practices. Information should be documented and implemented accordingly. Communication should happen in an open communication culture that enables discussion, the opportunity to have debriefing discussions and the entire staff can feel they are heard. For effective communication, it is also important that staff are active themselves in information collecting about the essential information needed in patient care. In mental health nursing, it is important to pay attention to all elements of communication and to develop processes concerning communication in multidisciplinary teams and across unit boundaries. The study aims to describe which communication elements support patient safety in psychiatric inpatient care from the viewpoint of the nursing staff. Communication is an essential part of care and one of the core competencies of the psychiatric care. It enables safe and quality patient care. Errors in health care are often connected with poor communication. The study brings needed insight from the psychiatric care view to the topic. The data were gathered from semi-structured interviews in which 26 nurses were asked to describe the elements that constitute patient safety in psychiatric inpatient care. The data were analysed inductively from the viewpoint of communication. The descriptions connected with communication formed a main category of communication elements that support patient safety; this main category was made up of three subcategories: fluent information transfer, open communication culture and being active in information collecting. Fluent information transfer consists of the practical implementation of communication; open communication

  7. A Portable MPI Implementation of the SPAI Preconditioner in ISIS++

    1997-01-01

    A parallel MPI implementation of the Sparse Approximate Inverse (SPAI) preconditioner is described. SPAI has proven to be a highly effective preconditioner, and is inherently parallel because it computes columns (or rows) of the preconditioning matrix independently. However, there are several problems that must be addressed for an efficient MPI implementation: load balance, latency hiding, and the need for one-sided communication. The effectiveness, efficiency, and scaling behavior of our implementation will be shown for different platforms.

  8. Multimethod communication for high-performance metacomputing applications

    SciTech Connect

    Foster, I.; Geisler, J.; Tuecke, S.; Kesselman, C.

    1996-12-31

    Metacomputing systems use high-speed networks to connect supercomputers, mass storage systems, scientific instruments, and display devices with the objective of enabling parallel applications to access geographically distributed computing resources. However, experience shows that high performance often can be achieved only if applications can integrate diverse communication substrates, transport mechanisms, and protocols, chosen according to where communication is directed, what is communicated, or when communication is performed. In this article, we describe a software architecture that addresses this requirement. This architecture allows multiple communication methods to be supported transparently in a single application, with either automatic or user-specified selection criteria guiding the methods used for each communication. We describe an implementation of this architecture, based on the Nexus communication library, and use this implementation to evaluate performance issues. The implementation supported a wide variety of applications in the I-WAY metacomputing experiment at Supercomputing 95; we use one of these applications to provide a quantitative demonstration of the advantages of multimethod communication in a heterogeneous networked environment.

    This paper describes a protocol to support point-to-point interprocessor communications with multicast. Dynamic, cut-through routing with local flow control is used to provide a high-throughput, low-latency communications path between processors. In addition multicast transmissions are available, in which copies of a packet are sent to multiple destinations using common resources as much as possible. Special packet terminators and selective buffering are introduced to avoid a deadlock during multicasts. A simulated implementation of the protocol is also described.

    While large numbers of proteomic biomarkers have been described, they are generally not implemented in medical practice. We have investigated the reasons for this shortcoming, focusing on hurdles downstream of biomarker verification, and describe major obstacles and possible solutions to ease valid biomarker implementation. Some of the problems lie in suboptimal biomarker discovery and validation, especially lack of validated platforms with well-described performance characteristics to support biomarker qualification. These issues have been acknowledged and are being addressed, raising the hope that valid biomarkers may start accumulating in the foreseeable future. However, successful biomarker discovery and qualification alone does not suffice for successful implementation. Additional challenges include, among others, limited access to appropriate specimens and insufficient funding, the need to validate new biomarker utility in interventional trials, and large communication gaps between the parties involved in implementation. To address this problem, we propose an implementation roadmap. The implementation effort needs to involve a wide variety of stakeholders (clinicians, statisticians, health economists, and representatives of patient groups, health insurance, pharmaceutical companies, biobanks, and regulatory agencies). Knowledgeable panels with adequate representation of all these stakeholders may facilitate biomarker evaluation and guide implementation for the specific context of use. This approach may avoid unwarranted delays or failure to implement potentially useful biomarkers, and may expedite meaningful contributions of the biomarker community to healthcare. PMID:22519700

    The implementation of an electronic medical record system in any large organization is as complex a task as the design of the system. During implementation, it is necessary that health care providers using the electronic system are able to communicate with colleagues who are continuing to work with the paper record. The Mayo Clinic in Rochester, Minnesota, is well along the path to implementing an electronic medical record system. One of the key issues addressed has been the need for the electronic system to integrate with the paper record. This need to function in the dual electronic/paper environment has placed new demands on printers, required revision of some paper forms, and required the electronic system to create facsimilies of paper record forms. In addition, new security issues have been raised. Dual paper/electronic environment issues are an important challenge in the implementation of an electronic medical record. PMID:8563257

  4. Asynchronous Message Service Reference Implementation

    NASA Technical Reports Server (NTRS)

    Burleigh, Scott C.

    2011-01-01

    This software provides a library of middleware functions with a simple application programming interface, enabling implementation of distributed applications in conformance with the CCSDS AMS (Consultative Committee for Space Data Systems Asynchronous Message Service) specification. The AMS service, and its protocols, implement an architectural concept under which the modules of mission systems may be designed as if they were to operate in isolation, each one producing and consuming mission information without explicit awareness of which other modules are currently operating. Communication relationships among such modules are self-configuring; this tends to minimize complexity in the development and operations of modular data systems. A system built on this model is a society of generally autonomous, inter-operating modules that may fluctuate freely over time in response to changing mission objectives, modules functional upgrades, and recovery from individual module failure. The purpose of AMS, then, is to reduce mission cost and risk by providing standard, reusable infrastructure for the exchange of information among data system modules in a manner that is simple to use, highly automated, flexible, robust, scalable, and efficient. The implementation is designed to spawn multiple threads of AMS functionality under the control of an AMS application program. These threads enable all members of an AMS-based, distributed application to discover one another in real time, subscribe to messages on specific topics, and to publish messages on specific topics. The query/reply (client/server) communication model is also supported. Message exchange is optionally subject to encryption (to support confidentiality) and authorization. Fault tolerance measures in the discovery protocol minimize the likelihood of overall application failure due to any single operational error anywhere in the system. The multi-threaded design simplifies processing while enabling application nodes to

  6. Improving Clinical Communication

    PubMed Central

    Parker, Julie; Coiera, Enrico

    2000-01-01

    Recent research has studied the communication behaviors of clinical hospital workers and observed a tendency for these workers to use communication behaviors that were often inefficient. Workers were observed to favor synchronous forms of communication, such as telephone calls and chance face-to-face meetings with colleagues, even when these channels were not effective. Synchronous communication also contributes to a highly interruptive working environment, increasing the potential for clinical errors to be made. This paper reviews these findings from a cognitive psychological perspective, focusing on current understandings of how human memory functions and on the potential consequences of interruptions on the ability to work effectively. It concludes by discussing possible communication technology interventions that could be introduced to improve the clinical communication environment and suggests directions for future research.

    After web 2.0 technologies experienced a phenomenal expansion and high acceptance among private users, considerations are now intensified to assess whether they can be equally applicable, beneficially employed and meaningfully implemented in an entrepreneurial context. The fast-paced rise of social software like weblogs or wikis and the resulting new form of communication via the Internet is however observed ambiguously in the corporate environment. This is why the particular choice of the platform or technology to be implemented in this field is strongly dependent on its future business case and field of deployment and should therefore be carefully considered beforehand, as this paper strongly suggests.

    Stark, Sheila; MacHale, Anita; Lennon, Eileen; Shaw, Lynne

    Government guidance and policy promotes the use of benchmarks as measures against which practice and care can be measured. This provides the motivation for practitioners to make changes to improve patient care. Adopting a systematic approach, practitioners can implement changes in practice quickly. The process requires motivation and communication between professionals of all disciplines. It provides a forum for sharing good practice and developing a support network. In this article the authors outline the initial steps taken by three PCGs in implementing the benchmarking process as they move towards primary care trust status. PMID:12212335

    While the demand for real-time broadband information access has grown and continues to grow at a rapid Pace, the need for a reconfigurable receiver system has increased. To achieve the goal to communicate with multiple shuttles at a time, a filter bank in polyphase structure is introduced. This paper presents the design and implementation for high-speed, high-performance, and fixed-point polyphase filter banks. The polyphase filter structure is designed such that the use of a fixed-point system has minimum impact on the performance of the filter. The final hardware implementation is done on a Xilinx FPGA chip.

    ABC identifies profitable volumes to give managers information to better manage volumes. Managers must balance the demand for service while maintaining a reasonable profit margin. Disparate systems work extremely well for their intended purposes, but they do not communicate with one another. The strength of the data they hold individually may be leveraged when implementing ABC methodology. Mayo Clinic in Rochester, Minnesota implemented a pilot of ABC to evaluate CT services where there is a high volume, multiple service location for cost comparison, variety of patient acuity and service mix, and large capital investments.The goal was to reveal the actual cost of CT services at the procedural level.

    This paper defines a new group communication model called concast communication. Being the counterpart to multicast, concast involves multiple senders transmitting to a single receiver. Concast communication is used in a wide range of applications including collaborative applications, report-in style applications, or just end-to-end acknowledgements in a reliable multicast protocol. This paper explores the issues involved in designing concast communication services. We examine various message combination methods including concatenation, compression, and reduction to reduce the traffic loads imposed on the network and packet implosion at the receiver. Group management operations such as group creation/deletion, joining/leaving, and concast routing are discussed. We also address transmission issues such as reliable delivery, flow control, congestion control, and QoS. We conclude the paper by presenting a concast communication model that we have been developing in the context of TMTP5. The model uses concast communication to implement reliable multicast and it shares concast trees with the multicast group whenever possible to reduce overhead costs.

  15. An analysis of communication policies in Kenya.

    Although Kenya's current 5-Year National Development Plan cites communications as a public policy issue in terms of the establishment of basic infrastructural facilities, little attention has been given to this area. At the national level, a more specific approach to communication policy demands the formulation of coherent policies and their implementation through adequate institutional bodies. However, most policymakers are poorly equipped to deal with communication questions since they are interdisciplinary, technically complex, and politically sensitive. Policymaking must be based on a database that allows a minimal level of resource assessment, an inventory of locally available resources, a projection of needs for imported resources, and a scenario for resource development. The institutional location and accountability of communication need to be defined. Moreover, in promoting the strategies of self-reliance and decentralization, communication policy must consider the 4 aspects of a national information system: function, resource inventory, structure content, an control. The 1st task is to carry out a needs assessment exercise that determines what is required from a communications policy. A related task is audience analysis. Also essential is the analysis of policies that guide and constrain system development and the distribution and nature of political and economic power. Finally, feedback mechanisms must be devised for the determination of policy impact. Methods helpful in analyzing policy impact include systems analysis, resource assessment, trend extrapolation, the Delphi technique, and brainstorming. PMID:12281810

    Using the S-band communications system, shuttle orbiter can communicate directly with the Earth via the Ground Spaceflight Tracking and Data Network (GSTDN) or via the Tracking and Data Relay Satellite System (TDRSS). The S-band frequencies provide the primary links for direct Earth and TDRSS communications during all launch and entry/landing phases of shuttle missions. On orbit, S-band links are used when TDRSS Ku-band is not available, when conditions require orbiter attitudes unfavorable to Ku-band communications, or when the payload bay doors are closed. the S-band communications functional requirements, the orbiter hardware configuration, and the NASA S-band communications network are described. The requirements and implementation concepts which resulted in techniques for shuttle S-band hardware development discussed include: (1) digital voice delta modulation; (2) convolutional coding/Viterbi decoding; (3) critical modulation index for phase modulation using a Costas loop (phase-shift keying) receiver; (4) optimum digital data modulation parameters for continuous-wave frequency modulation; (5) intermodulation effects of subcarrier ranging and time-division multiplexing data channels; (6) radiofrequency coverage; and (7) despreading techniques under poor signal-to-noise conditions. Channel performance is reviewed.

    We will discuss fungal communication in the context of fundamental biological functions including mating, growth, morphogenesis, and the regulation of fungal virulence determinants. We will address intraspecies but also interkingdom signaling by systematically discussing the sender of the message, the molecular message, and receiver. Analyzing communication shows the close coevolution of fungi with organisms present in their environment giving insights into multispecies communication. A better understanding of the molecular mechanisms underlying microbial communication will promote our understanding of the “fungal communicome.” PMID:21961006

    A number of laser communication link demonstrations from near Earth distances extending out to lunar ranges have been remarkably successful, demonstrating the augmented channel capacity that is accessible with the use of lasers for communications. The next hurdle on the path to extending laser communication and its benefits throughout the solar system and beyond is to demonstrate deep-space laser communication links. In this paper, concepts and technology development being advanced at the Jet Propulsion Laboratory (JPL) in order to enable deep-space link demonstrations to ranges of approximately 3 AU in the next decade, will be discussed.
