    In safety critical I/O and intercomputer communication networks, reliable message transmission is an important concern. Difficulties of communication and fault identification in networks arise primarily because the sender of a transmission cannot be identified with certainty, an intermediate node can corrupt a message without certainty of detection, and a babbling node cannot be identified and silenced without lengthy diagnosis and reconfiguration . Authentication protocols use digital signature techniques to verify the authenticity of messages with high probability. Such protocols appear to provide an efficient solution to many of these problems. The objective of this program is to develop, demonstrate, and evaluate intercomputer communication architectures which employ authentication. As a context for the evaluation, the authentication protocol-based communication concept was demonstrated under this program by hosting a real-time flight critical guidance, navigation and control algorithm on a distributed, heterogeneous, mixed redundancy system of workstations and embedded fault-tolerant computers.

  4. A highly reliable, autonomous data communication subsystem for an advanced information processing system

    1990-01-01

    The need to meet the stringent performance and reliability requirements of advanced avionics systems has frequently led to implementations which are tailored to a specific application and are therefore difficult to modify or extend. Furthermore, many integrated flight critical systems are input/output intensive. By using a design methodology which customizes the input/output mechanism for each new application, the cost of implementing new systems becomes prohibitively expensive. One solution to this dilemma is to design computer systems and input/output subsystems which are general purpose, but which can be easily configured to support the needs of a specific application. The Advanced Information Processing System (AIPS), currently under development has these characteristics. The design and implementation of the prototype I/O communication system for AIPS is described. AIPS addresses reliability issues related to data communications by the use of reconfigurable I/O networks. When a fault or damage event occurs, communication is restored to functioning parts of the network and the failed or damage components are isolated. Performance issues are addressed by using a parallelized computer architecture which decouples Input/Output (I/O) redundancy management and I/O processing from the computational stream of an application. The autonomous nature of the system derives from the highly automated and independent manner in which I/O transactions are conducted for the application as well as from the fact that the hardware redundancy management is entirely transparent to the application.

    Globalization and information and communication technology (ICT) continue to change us and the world we live in. Nursing stands at an opportunity intersection where challenging global health issues, an international workforce shortage, and massive growth of ICT combine to create a very unique space for nursing leadership and nursing intervention. Learning from prior successes in the field can assist nurse leaders in planning and advancing strategies for global health using ICT. Attention to lessons learned will assist in combating the technological apartheid that is already present in many areas of the globe and will highlight opportunities for innovative applications in health. ICT has opened new channels of communication, creating the beginnings of a global information society that will facilitate access to isolated areas where health needs are extreme and where nursing can contribute significantly to the achievement of "Health for All." The purpose of this article is to discuss the relationships between globalization, health, and ICT, and to illuminate opportunities for nursing in this flattening and increasingly interconnected world.

  7. Advanced quantum communication systems

    NASA Astrophysics Data System (ADS)

    Jeffrey, Evan Robert

    Quantum communication provides several examples of communication protocols which cannot be implemented securely using only classical communication. Currently, the most widely known of these is quantum cryptography, which allows secure key exchange between parties sharing a quantum channel subject to an eavesdropper. This thesis explores and extends the realm of quantum communication. Two new quantum communication protocols are described. The first is a new form of quantum cryptography---relativistic quantum cryptography---which increases communication efficiency by exploiting a relativistic bound on the power of an eavesdropper, in addition to the usual quantum mechanical restrictions intrinsic to quantum cryptography. By doing so, we have observed over 170% improvement in communication efficiency over a similar protocol not utilizing relativity. A second protocol, Quantum Orienteering, allows two cooperating parties to communicate a specific direction in space. This application shows the possibility of using joint measurements, or projections onto an entangled state, in order to extract the maximum useful information from quantum bits. For two-qubit communication, the maximal fidelity of communication using only separable operations is 73.6%, while joint measurements can improve the efficiency to 78.9%. In addition to implementing these protocols, we have improved several resources for quantum communication and quantum computing. Specifically, we have developed improved sources of polarization-entangled photons, a low-loss quantum memory for polarization qubits, and a quantum random number generator. These tools may be applied to a wide variety of future quantum and classical information systems.

  8. Communication training for advanced medical students improves information recall of medical laypersons in simulated informed consent talks – a randomized controlled trial

    2013-01-01

    Background Informed consent talks are mandatory before invasive interventions. However, the patients’ information recall has been shown to be rather poor. We investigated, whether medical laypersons recalled more information items from a simulated informed consent talk after advanced medical students participated in a communication training aiming to reduce a layperson’s cognitive load. Methods Using a randomized, controlled, prospective cross-over-design, 30 5th and 6th year medical students were randomized into two groups. One group received communication training, followed by a comparison intervention (early intervention group, EI); the other group first received the comparison intervention and then communication training (late intervention group, LI). Before and after the interventions, the 30 medical students performed simulated informed consent talks with 30 blinded medical laypersons using a standardized set of information. We then recorded the number of information items the medical laypersons recalled. Results After the communication training both groups of medical laypersons recalled significantly more information items (EI: 41 ± 9% vs. 23 ± 9%, p < .0001, LI 49 ± 10% vs. 35 ± 6%, p < .0001). After the comparison intervention the improvement was modest and significant only in the LI (EI: 42 ± 9% vs. 40 ± 9%, p = .41, LI 35 ± 6% vs. 29 ± 9%, p = .016). Conclusion Short communication training for advanced medical students improves information recall of medical laypersons in simulated informed consent talks. PMID:23374907

  14. Advanced satellite communication system

    Staples, Edward J.; Lie, Sen

    1992-05-01

    The objective of this research program was to develop an innovative advanced satellite receiver/demodulator utilizing surface acoustic wave (SAW) chirp transform processor and coherent BPSK demodulation. The algorithm of this SAW chirp Fourier transformer is of the Convolve - Multiply - Convolve (CMC) type, utilizing off-the-shelf reflective array compressor (RAC) chirp filters. This satellite receiver, if fully developed, was intended to be used as an on-board multichannel communications repeater. The Advanced Communications Receiver consists of four units: (1) CMC processor, (2) single sideband modulator, (3) demodulator, and (4) chirp waveform generator and individual channel processors. The input signal is composed of multiple user transmission frequencies operating independently from remotely located ground terminals. This signal is Fourier transformed by the CMC Processor into a unique time slot for each user frequency. The CMC processor is driven by a waveform generator through a single sideband (SSB) modulator. The output of the coherent demodulator is composed of positive and negative pulses, which are the envelopes of the chirp transform processor output. These pulses correspond to the data symbols. Following the demodulator, a logic circuit reconstructs the pulses into data, which are subsequently differentially decoded to form the transmitted data. The coherent demodulation and detection of BPSK signals derived from a CMC chirp transform processor were experimentally demonstrated and bit error rate (BER) testing was performed. To assess the feasibility of such advanced receiver, the results were compared with the theoretical analysis and plotted for an average BER as a function of signal-to-noise ratio. Another goal of this SBIR program was the development of a commercial product. The commercial product developed was an arbitrary waveform generator. The successful sales have begun with the delivery of the first arbitrary waveform generator.

    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.

    In recent years, the use of integrated technologies for applications in the field of quantum information processing and communications has made great progress. The resulting devices feature valuable characteristics such as scalability, reproducibility, low cost and interconnectivity, and have the potential to revolutionize our computation and communication practices in the future, much in the way that electronic integrated circuits have drastically transformed our information processing capacities since the last century. Among the multiple applications of integrated quantum technologies, this review will focus on typical components of quantum communication systems and on overall integrated system operation characteristics. We are interested in particular in the use of photonic integration platforms for developing devices necessary in quantum communications, including sources, detectors and both passive and active optical elements. We also illustrate the challenges associated with performing quantum communications on chip, by using the case study of quantum key distribution—the most advanced application of quantum information science. We conclude with promising perspectives in this field.

    Usually, a hydrometeorological information system is faced with great data flows, but the data levels are often excessive, depending on the observed region of the water. The paper presents advanced buoy communication technologies based on multiagent interaction and data exchange between several monitoring system nodes. The proposed management of buoy communication is based on a clustering algorithm, which enables the performance of the hydrometeorological information system to be enhanced. The experiment is based on the design and analysis of the inexpensive but reliable Baltic Sea autonomous monitoring network (buoys), which would be able to continuously monitor and collect temperature, waviness, and other required data. The proposed approach of multiagent based buoy communication enables all the data from the costal-based station to be monitored with limited transition speed by setting different tasks for the agent-based buoy system according to the clustering information.

    1993-01-01

    This paper evaluates the quantization process in the context of the end-to-end performance of the visual-communication channel. Results show that the trade-off between data transmission and visual quality revolves around the information in the acquired signal, not around its energy. Improved information efficiency is gained by frequency dependent quantization that maintains the information capacity of the channel and reduces the entropy of the encoded signal. Restorations with energy bit-allocation lose both in sharpness and clarity relative to restorations with information bit-allocation. Thus, quantization with information bit-allocation is preferred for high information efficiency and visual quality in optimized visual communication.

    The primary goal of the Adaptive Vision Laboratory Research project was to develop advanced computer vision systems for automatic target recognition. The approach used in this effort combined several machine learning paradigms including evolutionary learning algorithms, neural networks, and adaptive clustering techniques to develop the E-MOR.PH system. This system is capable of generating pattern recognition systems to solve a wide variety of complex recognition tasks. A series of simulation experiments were conducted using E-MORPH to solve problems in OCR, military target recognition, industrial inspection, and medical image analysis. The bulk of the funds provided through this grant were used to purchase computer hardware and software to support these computationally intensive simulations. The payoff from this effort is the reduced need for human involvement in the design and implementation of recognition systems. We have shown that the techniques used in E-MORPH are generic and readily transition to other problem domains. Specifically, E-MORPH is multi-phase evolutionary leaming system that evolves cooperative sets of features detectors and combines their response using an adaptive classifier to form a complete pattern recognition system. The system can operate on binary or grayscale images. In our most recent experiments, we used multi-resolution images that are formed by applying a Gabor wavelet transform to a set of grayscale input images. To begin the leaming process, candidate chips are extracted from the multi-resolution images to form a training set and a test set. A population of detector sets is randomly initialized to start the evolutionary process. Using a combination of evolutionary programming and genetic algorithms, the feature detectors are enhanced to solve a recognition problem. The design of E-MORPH and recognition results for a complex problem in medical image analysis are described at the end of this report. The specific task involves the

    Late in the 1980's the information system of Japanese corporation has been operated strategically to strengthen its competitive position in markets rather than to make corporate management efficient. Therefore, information-oriented policy in the corporation is making remarkable progress. This policy expands the intelligence activity in the corporation and also leads to the extension of the market in an information industry. In this environment closed corporate system is transformed into open one. For this system network and database are important managerial resources.

    As technology such as computer, office automation equipments, industrial robots have come into wide use, mental and physical fatigue called technostress as well as health injury has become social issues. Some people attribute this technostress to psychological unrest created by masscommunication or to computer works. On the other hand other people have been conducting investigations of the stress caused by programming works, and gathering information on the related symptoms. The expression and causes of technostress are diverse depending on the kind of computer related labor, therefore, it is necessary to have delicate and detailed countermeasures against it. However, after all technostress is much concerned with individuals' life style and industrial climate.

    This article discusses the U.S. and European national strategies and policies for information society. Coping with the declining competitiveness in high-tech products and Japanese technological advantages both have been trying hard to strengthen technology base and to deregulate the telecommunications services markets. The U.S. approach in 1980's, unlike its liberalist principle, has been characterized by technological protectlonism and defense-oriented policies. European Communities' approach has been more comprehensive and systematic, investing heavily telecommunication infrastructure, deregulating domestic market, and promoting cooperation of member countries. However, both of these approaches have, so far, been unable to achieve a considerable success.

  3. Quantum communication and information processing

    NASA Astrophysics Data System (ADS)

    Beals, Travis Roland

    Quantum computers enable dramatically more efficient algorithms for solving certain classes of computational problems, but, in doing so, they create new problems. In particular, Shor's Algorithm allows for efficient cryptanalysis of many public-key cryptosystems. As public key cryptography is a critical component of present-day electronic commerce, it is crucial that a working, secure replacement be found. Quantum key distribution (QKD), first developed by C.H. Bennett and G. Brassard, offers a partial solution, but many challenges remain, both in terms of hardware limitations and in designing cryptographic protocols for a viable large-scale quantum communication infrastructure. In Part I, I investigate optical lattice-based approaches to quantum information processing. I look at details of a proposal for an optical lattice-based quantum computer, which could potentially be used for both quantum communications and for more sophisticated quantum information processing. In Part III, I propose a method for converting and storing photonic quantum bits in the internal state of periodically-spaced neutral atoms by generating and manipulating a photonic band gap and associated defect states. In Part II, I present a cryptographic protocol which allows for the extension of present-day QKD networks over much longer distances without the development of new hardware. I also present a second, related protocol which effectively solves the authentication problem faced by a large QKD network, thus making QKD a viable, information-theoretic secure replacement for public key cryptosystems.

    IEC programs increase the knowledge and motivation of decision makers with power over determinants of population growth and socioeconomic development. Information may improve the awareness of public and private officials of population questions and of the form in which they are treated. Information activities involve demographic growth and spatial distribution of the population, the demographic and health benefits of family planning, and the danger of sexually transmitted diseases and AIDS. The mass media are the main source of information, but in developing countries various forms of folk media enjoyed by the public may also be used. Technical journals and other information networks are available for the professional audience. Population communication promotes acceptance and use of family planning. Radio and television series that incorporate family planning themes, popular music that mentions population problems, and broadcasts of telephone question and answer programs have been influential in some countries. Such informational programs may be very important in regions with low levels of literacy. Programs targeted to adolescents may help resolve problems of early pregnancy. More than 80 countries include population education in their school curriculum. The objectives vary, but they generally include making students aware of population problems and of their own responsibilities. Population questions are also included in many professional training programs.

    The next generation of civil transport aircraft will depend increasingly upon ground-air-ground and satellite data link for information critical to safe and efficient air transportation. Previous studies which examined the concept of display-based communications in addition to, or in lieu of, conventional voice transmissions are reviewed. A full-mission flight simulation comparing voice and display-based communication modes in an advanced transport aircraft is also described. The results indicate that a display-based mode of information transfer does not result in significantly increased aircrew workload, but does result in substantially increased message acknowledgment times when compared to conventional voice transmissions. User acceptance of the display-based communication system was generally high, replicating the findings of previous studies. However, most pilots tested expressed concern over the potential loss of information available from frequency monitoring which might result from the introduction of discrete address communications. Concern was expressed by some pilots for the reduced time available to search for conflicting traffic when using the communications display system. The implications of the findings for the design of display-based communications are discussed.

    Simulation for a ground station located at 44.5 deg latitude. The Advanced Communications Architecture Demonstration (ACAD) is a concept architecture to provide high-rate Ka-band (27-GHz) direct-to-ground delivery of payload data from the International Space Station. This new concept in delivering data from the space station targets scientific experiments that buffer data onboard. The concept design provides a method to augment the current downlink capability through the Tracking Data Relay Satellite System (TDRSS) Ku-band (15-GHz) communications system. The ACAD concept pushes the limits of technology in high-rate data communications for space-qualified systems. Research activities are ongoing in examining the various aspects of high-rate communications systems including: (1) link budget parametric analyses, (2) antenna configuration trade studies, (3) orbital simulations (see the preceding figure), (4) optimization of ground station contact time (see the following graph), (5) processor and storage architecture definition, and (6) protocol evaluations and dependencies.

    Advanced network applications such as remote instrument control, collaborative environments, and remote I/O are distinguished by traditional applications such as videoconferencing by their need to create multiple, heterogeneous flows with different characteristics. For example, a single application may require remote I/O for raw datasets, shared controls for a collaborative analysis system, streaming video for image rendering data, and audio for collaboration. Furthermore, each flow can have different requirements in terms of reliability, network quality of service, security, etc. They argue that new approaches to communication services, protocols, and network architecture are required both to provide high-level abstractions for common flow types and to support user-level management of flow creation and quality. They describe experiences with the development of such applications and communication services.

    Since communication networks such as the Internet, which is regarded as a complex network, have recently become a huge scale and a lot of data pass through them, the improvement of packet routing strategies for transport is one of the most significant themes in the study of computer networks. It is especially important to find routing strategies which can bear as many traffic as possible without congestion in complex networks. First, using neural networks, we introduce a strategy for packet routing on complex networks, where path lengths and queue lengths in nodes are taken into account within a framework of statistical physics. Secondly, instead of using shortest paths, we propose efficient paths which avoid hubs, nodes with a great many degrees, on scale-free networks with a weight of each node. We improve the heuristic algorithm proposed by Danila et. al. which optimizes step by step routing properties on congestion by using the information of betweenness, the probability of paths passing through a node in all optimal paths which are defined according to a rule, and mitigates the congestion. We confirm the new heuristic algorithm which balances traffic on networks by achieving minimization of the maximum betweenness in much smaller number of iteration steps. Finally, We model virus spreading and data transfer on peer-to-peer (P2P) networks. Using mean-field approximation, we obtain an analytical formulation and emulate virus spreading on the network and compare the results with those of simulation. Moreover, we investigate the mitigation of information traffic congestion in the P2P networks.

    An advanced satellite payload is proposed for single hop linking of mobile terminals of all classes as well as Very Small Aperture Terminal's (VSAT's). It relies on an intensive use of communications on-board processing and beam hopping for efficient link design to maximize capacity and a large satellite antenna aperture and high satellite transmitter power to minimize the cost of the ground terminals. Intersatellite links are used to improve the link quality and for high capacity relay. Power budgets are presented for links between the satellite and mobile, VSAT, and hub terminals. Defeating the effects of shadowing and fading requires the use of differentially coherent demodulation, concatenated forward error correction coding, and interleaving, all on a single link basis.

    An updated traffic projection for U.S. domestic satellite communications service covering a period of 15 years; mid-1980 to mid-1995 was prepared. This model takes into account expected technology advances and reductions in transmission costs, legislative and regulatory changes permitting increased competition, and rising energy costs which will encourage more extensive substitution of telecommunications for travel. The historical development and current status of satellite systems are discussed as well as the characteristics of follow-on systems. Orbital arc utilization, spacecraft configuration for single shuttle launch, Earth station configuration, and system costs are examined. Areas which require technology development include multiple beam frequency reuse antennas, on-board switching, intersatellite links, and ka-band operation. Packing and deployment schemes for enclosing the satellite within the shuttle orbiter bay must also be devised.

    Today it is pointed out that social acceptance of new science & technology should be decided not only by the experts but also by citizens, because new science & technology gives great affects on the daily life of citizens. This paper deals with information systems to support communication for citizens. Here the communication for citizens is divided into two aspects of communication, dialogue with citizens and information presentation to citizens. First, the problems of communication for citizens are analyzed and the methods and approaches to cope with the problems are investigated. Then, research projects to enhance this type of communication are introduced concretely. We believe the importance of communication support for citizens will be increased in near future.

    As the June 2009 deadline set by the MINER Act grows near, several technologies have emerged as possible options for communicating and tracking underground coal miners in the event of an emergency or disaster. NIOSH is currently deciding how best to invest $10 million assigned by Congress under an Emergency Supplementary Appropriations Act (ESA) to research and develop mine safety technology. Medium and ultra high frequency (UHF) systems seem to be leading the pack with radio frequency identification (RFID) tags serving as the tracking system. Wireless mesh systems can serve as a communications infrastructure and they can do much more. Even more technologies continue to emerge, such as inertial navigation tracking systems. Mines are discovering the wonders of modern voice and data communications underground. Still no one know if it is economically practical to design a system that will function after a coal mine explosion. From the nineteen systems submitted to MSHA's request for information (RFI), six systems were selected that represented most of the technologies that had been proposed: the Rajant Breadcrumb, Innovative Wireless, Concurrent Technologies/Time Domain, Transtek, Gamma Services, and the Kutta Consulting systems. They were tested at CONSOL Energy's McElroy mine in April 2006. MSHA felt that all of those systems needed a significant amount of work before they were ready for use in a underground coal mining environment. The agency continues to work with these, and other manufacturers, to assist in arranging for field demonstration and then to gain MSHA approval.

    This paper will address key technologies under development at the NASA Glenn Research Center designed to provide architecture-level impacts. Specifically, we will describe deployable antennas, a new type of phased array antenna and novel power amplifiers. The evaluation of architectural influence can be conducted from two perspectives where said architecture can be analyzed from either the top-down to determine the areas where technology improvements will be most beneficial or from the bottom-up where each technology s performance advancement can affect the overall architecture s performance. This paper will take the latter approach with focus on some technology improvement challenges and address architecture impacts. For example, using data rate as a performance metric, future exploration scenarios are expected to demand data rates possibly exceeding 1 Gbps. To support these advancements in a Mars scenario, as an example, Ka-band and antenna aperture sizes on the order of 10 meters will be required from Mars areostationary platforms. Key technical challenges for a large deployable antenna include maximizing the ratio of deployed-to-packaged volume, minimizing aerial density, maintaining RMS surface accuracy to within 1/20 of a wavelength or better, and developing reflector rigidization techniques. Moreover, the high frequencies and large apertures manifest a new problem for microwave engineers that are familiar to optical communications specialists: pointing. The fine beam widths and long ranges dictate the need for electronic or mechanical feed articulation to compensate for spacecraft attitude control limitations.

    Information and communication technologies (ICTs) are electronic tools used to convey, manipulate and store information. The exponential growth of Internet access and ICTs greatly influenced social, political, and economic processes in the United States, and worldwide. Regardless of the level of practice, ICTs will continue influencing the careers of social workers and the clients they serve. ICTs have received some attention in the social work literature and curriculum, but we argue that this level of attention is not adequate given their ubiquity, growth and influence, specifically as it relates to upholding social work ethics. Significant attention is needed to help ensure social workers are responsive to the technological changes in the health care system, including the health care infrastructure and use of technology among clients. Social workers also need ICT competencies in order to effectively lead different types of social change initiatives or collaborate with professionals of other disciplines who are using ICTs as part of existing strategies. This paper also identifies potential pitfalls and challenges with respect to the adoption of ICTs, with recommendations for advancing their use in practice, education, and research. PMID:21691444

    Beacom, Amanda M; Newman, Sandra J

    2010-01-01

    Interest in the communication of health information among disadvantaged populations has increased in recent years with the shift from a model of patient-provider communication to one of a more empowered healthcare consumer; with the use of new communication technologies that increase the number of channels through which health information may be accessed; and with the steadily increasing number of people without health insurance. Three separate research literatures contribute to our current understanding of this issue. In the medicine and public health literature, disparities in health access and outcomes among socioeconomic, ethnic, and racial groups are now well documented. In the information sciences literature, scholars note that on a continuum of health information behaviors, ranging from information avoidance and nonseeking to active seeking, nonseeking behaviors are associated with disadvantaged populations. In the communication literature, enthusiasm over the technology-driven growth of online health information seeking is tempered by evidence supporting the knowledge gap hypothesis, which indicates that as potential access to health information increases, systematic gaps in health knowledge also increase as groups with higher socioeconomic status acquire this information at a faster rate than those with lower socioeconomic status. A number of diverse strategies show promise in reducing information and health disparities, including those that focus on technology, such as programs to increase computer and Internet access, skills, and comprehension; those that focus on interpersonal communication, such as the community health worker model; and those that focus on mass media channels, such as entertainment education.

    The application of quantum mechanics to information related fields such as communication, computation and cryptography is a fast growing line of research that has been witnessing an outburst of theoretical and experimental results, with possible practical applications. On the one hand, quantum cryptography with its impact on secrecy of transmission is having its first important actual implementations; on the other hand, the recent advances in quantum optics, ion trapping, BEC manipulation, spin and quantum dot technologies allow us to put to direct test a great deal of theoretical ideas and results. These achievements have stimulated a reborn interest in various aspects of quantum mechanics, creating a unique interplay between physics, both theoretical and experimental, mathematics, information theory and computer science. In view of all these developments, it appeared timely to organize a meeting where graduate students and young researchers could be exposed to the fundamentals of the theory, while senior experts could exchange their latest results. The activity was structured as a school followed by a workshop, and took place at The Abdus Salam International Center for Theoretical Physics (ICTP) and The International School for Advanced Studies (SISSA) in Trieste, Italy, from 12-23 June 2006. The meeting was part of the activity of the Joint European Master Curriculum Development Programme in Quantum Information, Communication, Cryptography and Computation, involving the Universities of Cergy-Pontoise (France), Chania (Greece), Leuven (Belgium), Rennes1 (France) and Trieste (Italy). This special issue of Journal of Physics A: Mathematical and Theoretical collects 22 contributions from well known experts who took part in the workshop. They summarize the present day status of the research in the manifold aspects of quantum information. The issue is opened by two review articles, the first by G Adesso and F Illuminati discussing entanglement in continuous variable

    This paper depicts the Advanced Communication Technology Satellite (ACTS) system as a global central office switch. The ground portion of the system is the collection of earth stations or T1-VSAT's (T1 very small aperture terminals). The control software for the T1-VSAT's resides in a single CPU. The software consists of two modules, the modem manager and the call manager. The modem manager (MM) controls the RF modem portion of the T1-VSAT. It processes the orderwires from the satellite or from signaling generated by the call manager (CM). The CM controls the Recom Laboratories MSPs by receiving signaling messages from the stacked MSP shelves ro units and sending appropriate setup commands to them. There are two methods used to setup and process calls in the CM; first by dialing up a circuit using a standard telephone handset or, secondly by using an external processor connected to the CPU's second COM port, by sending and receiving signaling orderwires. It is the use of the external processor which permits the ISDN (Integrated Services Digital Network) Signaling Processor to implement ISDN calls. In August 1993, the initial testing of the ISDN Signaling Processor was carried out at ACTS System Test at Lockheed Marietta, Princeton, NJ using the spacecraft in its test configuration on the ground.

    2005-01-01

    This article presents a comparative study about social workers' interdisciplinary advance directive communication practices with patients at several hospitals located in upstate New York. The sample consisted of physicians (n=32), nurses (n=74), and social workers (n=29). The research surveyed advance directive communication practices by discipline utilizing a self-administered questionnaire. Advance directive communication was operationalized as a cumulative process incorporating the following phases that were measured as scales: initiation of the topic, disclosure of information, identification of a surrogate decision-maker, discussion of treatment options, elicitation of patient values, interaction with family members, and collaboration with other health care professionals. Results suggest that social workers offer distinct skills in their advance directive communication practices and discuss advance directives more frequently than either physicians or nurses.

    2000-01-01

    For ships at sea. satellites provide the only option for high data rate (HDR), long haul communications. Furthermore the demand for HDR satellite communications (SATCOM) for military and commercial ships. and other offshore platforms is increasing. Presently the bulk of this maritime HDR SATCOM connectivity is provided via C-band and X-band. However, the shipboard antenna sizes required to achieve a data rate of, say T 1 (1.544 Mbps) with present C-/X-band SATCOM systems range from seven to ten feet in diameter. This limits the classes of ships to which HDR services can be provided to those which are large enough to accommodate the massive antennas. With its high powered K/Ka-band spot beams, the National Aeronautics and Space Administration's (NASA) Advanced Communications Technology Satellite (ACTS) was able to provide T I and higher rate services to ships at sea using much smaller shipboard antennas. This paper discusses three shipboard HDR SATCOM demonstrations that were conducted with ACTS between 1996 and 1998. The first demonstration involved a 2 Mbps link provided to the seismic survey ship MN Geco Diamond equipped with a 16-inch wide, 4.5-inch tall, mechanically steered slotted waveguide array antenna developed by the Jet Propulsion Laboratory. In this February 1996 demonstration ACTS allowed supercomputers ashore to process Geco Diamond's voluminous oceanographic seismic data in near real time. This capability allowed the ship to adjust its search parameters on a daily basis based on feedback from the processed data, thereby greatly increasing survey efficiency. The second demonstration was conducted on the US Navy cruiser USS Princeton (CG 59) with the same antenna used on Geco Diamond. Princeton conducted a six-month (January-July 1997) Western Hemisphere solo deployment during which time T1 connectivity via ACTS provided the ship with a range of valuable tools for operational, administrative and quality-of-life tasks.

    NASA Astrophysics Data System (ADS)

    Alouini, Mehdi; Bretenaker, Fabien

    2015-10-01

    The applications of lasers in industry are numerous. It is of course beyond the scope of this book to give an overview of these applications. Rather than trying and failing in doing so, we have chosen in this chapter to illustrate the unique properties of lasers in four different fields. The two first applications described in this chapter, namely optical telecommunications (Section 3.1) and optical information storage (Section 3.2), highlight the contribution of the spatial coherence of the laser. The third one, namely the ring laser gyroscope (Section 3.3), illustrates the amazing spectral purity that can be provided by laser light. Finally, the fourth one, known under the generic acronym LIDAR (Section 3.4), can use different laser properties, depending on its implementation. It can be based on the laser spatial coherence, the laser temporal coherence, and/or on the laser ability to emit powerful short pulses.

    When people interact, affective information is transmitted between their brains. Modern imaging techniques permit to investigate the dynamics of this brain-to-brain transfer of information. Here, we used information-based functional magnetic resonance imaging (fMRI) to investigate the flow of affective information between the brains of senders and perceivers engaged in ongoing facial communication of affect. We found that the level of neural activity within a distributed network of the perceiver's brain can be successfully predicted from the neural activity in the same network in the sender's brain, depending on the affect that is currently being communicated. Furthermore, there was a temporal succession in the flow of affective information from the sender's brain to the perceiver's brain, with information in the perceiver's brain being significantly delayed relative to information in the sender's brain. This delay decreased over time, possibly reflecting some 'tuning in' of the perceiver with the sender. Our data support current theories of intersubjectivity by providing direct evidence that during ongoing facial communication a 'shared space' of affect is successively built up between senders and perceivers of affective facial signals.

  4. Standards Advisor-Advanced Information Technology for Advanced Information Delivery

    NASA Technical Reports Server (NTRS)

    Hawker, J. Scott

    2003-01-01

    Developers of space systems must deal with an increasing amount of information in responding to extensive requirements and standards from numerous sources. Accessing these requirements and standards, understanding them, comparing them, negotiating them and responding to them is often an overwhelming task. There are resources to aid the space systems developer, such as lessons learned and best practices. Again, though, accessing, understanding, and using this information is often more difficult than helpful. This results in space systems that: 1. Do not meet all their requirements. 2. Do not incorporate prior engineering experience. 3. Cost more to develop. 4. Take longer to develop. The NASA Technical Standards Program (NTSP) web site at http://standards.nasa.gov has made significant improvements in making standards, lessons learned, and related material available to space systems developers agency-wide. The Standards Advisor was conceived to take the next steps beyond the current product, continuing to apply evolving information technology that continues to improve information delivery to space systems developers. This report describes the features of the Standards Advisor and suggests a technical approach to its development.

  5. Advanced materials: Information and analysis needs

    SciTech Connect

    Curlee, T.R.; Das, S.; Lee, R.; Trumble, D.

    1990-09-01

    This report presents the findings of a study to identify the types of information and analysis that are needed for advanced materials. The project was sponsored by the US Bureau of Mines (BOM). It includes a conceptual description of information needs for advanced materials and the development and implementation of a questionnaire on the same subject. This report identifies twelve fundamental differences between advanced and traditional materials and discusses the implications of these differences for data and analysis needs. Advanced and traditional materials differ significantly in terms of physical and chemical properties. Advanced material properties can be customized more easily. The production of advanced materials may differ from traditional materials in terms of inputs, the importance of by-products, the importance of different processing steps (especially fabrication), and scale economies. The potential for change in advanced materials characteristics and markets is greater and is derived from the marriage of radically different materials and processes. In addition to the conceptual study, a questionnaire was developed and implemented to assess the opinions of people who are likely users of BOM information on advanced materials. The results of the questionnaire, which was sent to about 1000 people, generally confirm the propositions set forth in the conceptual part of the study. The results also provide data on the categories of advanced materials and the types of information that are of greatest interest to potential users. 32 refs., 1 fig., 12 tabs.

    1982-01-01

    Design information is prepared by many organizations to provide a basis for quality control, standardization, and cost containment in constructed facilities. Usually, this information is used by many people other than designers to evaluate existing facilities, plan renovations or new construction projects, define detailed requirements, or design a project. This report discusses a method for developing habitability design information and communicating it effectively to help insure that it is used. The procedure explains how to manage the process of developing habitability design information, including planning a document, collecting and evaluating resource materials, and writing and formatting habitability design information. Information needs of typical readers are defined, and many examples, including important format features, are provided to assist the readers. Principles of writing habitability design information documents are summarized.

    1989-01-01

    The Advanced Information Processing System (AIPS) is a multi-computer architecture composed of hardware and software building blocks that can be configured to meet a broad range of application requirements. The hardware building blocks are fault-tolerant, general-purpose computers, fault-and damage-tolerant networks (both computer and input/output), and interfaces between the networks and the computers. The software building blocks are the major software functions: local system services, input/output, system services, inter-computer system services, and the system manager. The foundation of the local system services is an operating system with the functions required for a traditional real-time multi-tasking computer, such as task scheduling, inter-task communication, memory management, interrupt handling, and time maintenance. Resting on this foundation are the redundancy management functions necessary in a redundant computer and the status reporting functions required for an operator interface. The functional requirements, functional design and detailed specifications for all the local system services are documented.

  9. Study of repeater technology for advanced multifunctional communications satellites

    1972-01-01

    Investigations are presented concerning design concepts and implementation approaches for the satellite communication repeater subsystems of advanced multifunctional satellites. In such systems the important concepts are the use of multiple antenna beams, repeater switching (routing), and efficient spectrum utilization through frequency reuse. An information base on these techniques was developed and tradeoff analyses were made of repeater design concepts, with the work design taken in a broad sense to include modulation beam coverage patterns. There were five major areas of study: requirements analysis and processing; study of interbeam interference in multibeam systems; characterization of multiple-beam switching repeaters; estimation of repeater weight and power for a number of alternatives; and tradeoff analyses based on these weight and power data.

    The Advanced Communication Technology Satellite (ACTS) is a key to reaching NASA's goal of developing high-risk, advanced communications technology using multiple frequency bands to support the nation's future communication needs. Using the multiple, dynamic hopping spot beams, and advanced on board switching and processing systems, ACTS will open a new era in communications satellite technology. One of the key technologies to be validated as part of the ACTS program is the multibeam antenna with rapidly reconfigurable hopping and fixed spot beam to serve users equipped with small-aperature terminals within the coverage areas. The proposed antenna technology experiments are designed to evaluate in-orbit ACTS multibeam antenna performance (radiation pattern, gain, cross pol levels, etc.).

    2005-01-01

    The concept of an information barrier, or IB, has been widely discussed for a number of years. An IB is used in a measurement system that contains classified information to prevent the release (either intentional or inadvertent) of the classified information while still allowing an inspecting party to reach independent conclusions as to the contents of a storage container. Typically, an IB would be used in a measurement system regime that requires the owner of certain storage containers to declare the contents of the containers (in unclassified terms) and an inspecting party to confirm this declaration. The IB allows the owner's declaration to be confirmed without releasing any classified information to the inspecting party. Most IB design concepts are based on two attribute measruement systems (AMSs) that were built and demonstrated in the US in 1999 and 2000. These IBs relied heavily on simple hardware implementations and performed well in a 'one-time' demonstration mode. However, implementation of an AMS in a long-term verification regime will place a different set of requirements on the entire AMS system - and the IB, in particular. In this paper, they will concentrate on the effects of changing constraints on IB design, new IB concepts that have been developed since the earlier demonstrations, and design concepts that have been developed within a number of related verification regimes.

    Visible light communication (VLC) is an emerging technology in optical wireless communication (OWC) that has attracted worldwide research in recent years. VLC can combine communication and illumination together, which could be applied in many application scenarios such as visible light communication local area networks (VLANs), indoor localization, and intelligent lighting. In recent years, pioneering and significant work have been made in the field of VLC. In this paper, an overview of the recent progress in VLC is presented. We also demonstrate our recent experiment results including bidirectional 100 Mbit/s VLAN or Li-Fi system based on OOK modulation without blue filter. The VLC systems that we proposed are good solutions for high-speed VLC application systems with low-cost and low-complexity. VLC technology shows a bright future due to its inherent advantages, shortage of RF spectra and ever increasing popularity of white LEDs.

    Tactical operations require military commanders to be mobile and have a high level of independence in their actions. Communications capabilities providing intelligence and command orders in these tactical situations have been limited to simple voice communications or low-rate narrow bandwidth communications because of the need for immediate reliable connectivity. The Advanced Communications Technology Satellite (ACTS) has brought an improved communications tool to the tactical commander giving the ability to gain access to a global communications system using high data rates and wide bandwidths. The Army has successfully tested this new capability of bandwidth-on-demand and high data rates for commanders in real-world conditions during Operation UPHOLD DEMOCRACY in Haiti during the fall and winter of 1994. This paper examines ACTS use by field commanders and details the success of the ACTS system in support of a wide variety of field condition command functions.

    This is the final report of a one-year, Laboratory Directed Research and Development (LDRD) project at Los Alamos National Laboratory (LANL). In a modern information-controlled society the importance of fast computational algorithms facilitating data compression and image analysis cannot be overemphasized. Feature extraction and pattern recognition are key to many LANL projects and the same types of dimensionality reduction and compression used in source coding are also applicable to image understanding. The authors have begun developing wavelet coding which decomposes data into different length-scale and frequency bands. New transform-based source-coding techniques offer potential for achieving better, combined source-channel coding performance by using joint-optimization techniques. They initiated work on a system that compresses the video stream in real time, and which also takes the additional step of analyzing the video stream concurrently. By using object-based compression schemes (where an object is an identifiable feature of the video signal, repeatable in time or space), they believe that the analysis is directly related to the efficiency of the compression.

    This assessment of visual communication deals with image gathering, coding, and restoration as a whole rather than as separate and independent tasks. The approach focuses on two mathematical criteria, information and fidelity, and on their relationships to the entropy of the encoded data and to the visual quality of the restored image. Past applications of these criteria to the assessment of image coding and restoration have been limited to the link that connects the output of the image-gathering device to the input of the image-display device. By contrast, the approach presented in this paper explicitly includes the critical limiting factors that constrain image gathering and display. This extension leads to an end-to-end assessment theory of visual communication that combines optical design with digital processing.

    Polymer Optical Fibres (POFs) show clear advantages compared to copper and glass fibres. In essence, POFs are inexpensive, space-saving and not susceptible to electromagnetic interference. Thus, the usage of POFs have become a reasonable alternative in short distance data communication. Today, POFs are applied in a wide number of applications due to these specific advantages. These applications include automotive communication systems and in-house-networks. State-of-the-art is to transmit data with only one channel over POF, this limits the bandwidth. To solve this problem, an integrated MUX/DEMUX-element for WDM over POF is designed and developed to use multiple channels. This integration leads to low costs, therefore this component is suitable for mass market applications. The fundamental idea is to separate the chromatic parts of the light in its monochromatic components by means of a grating based on an aspheric mirror. Due to the high NA of the POF the setup has to be designed in a 3D-approach. Therefore this setup cannot be compared with the planar solutions available on market, they would result high losses in the 3rd dimension. To achieve a fast and optimized design an optical simulation program is used. Particular attention has to be paid to the design of the POF as a light source in the simulation program and the optimisation of the grating. The following realization of the demultiplexer is planed to be done with injection molding. This technology offers easy and very economical processing. These advantages make this technology first choice for optical components in the low-cost array.

    The digital revolution affects the environment on several levels. Most directly, information and communications technology (ICT) has environmental impacts through the manufacturing, operation and disposal of devices and network equipment, but it also provides ways to mitigate energy use, for example through smart buildings and teleworking. At a broader system level, ICTs influence economic growth and bring about technological and societal change. Managing the direct impacts of ICTs is more complex than just producing efficient devices, owing to the energetically expensive manufacturing process, and the increasing proliferation of devices needs to be taken into account.

  10. By-product information can stabilize the reliability of communication.

    PubMed

    Schaefer, H Martin; Ruxton, G D

    2012-12-01

    Although communication underpins many biological processes, its function and basic definition remain contentious. In particular, researchers have debated whether information should be an integral part of a definition of communication and how it remains reliable. So far the handicap principle, assuming signal costs to stabilize reliable communication, has been the predominant paradigm in the study of animal communication. The role of by-product information produced by mechanisms other than the communicative interaction has been neglected in the debate on signal reliability. We argue that by-product information is common and that it provides the starting point for ritualization as the process of the evolution of communication. Second, by-product information remains unchanged during ritualization and enforces reliable communication by restricting the options for manipulation and cheating. Third, this perspective changes the focus of research on communication from studying signal costs to studying the costs of cheating. It can thus explain the reliability of signalling in many communication systems that do not rely on handicaps. We emphasize that communication can often be informative but that the evolution of communication does not cause the evolution of information because by-product information often predates and stimulates the evolution of communication. Communication is thus a consequence but not a cause of reliability. Communication is the interplay of inadvertent, informative traits and evolved traits that increase the stimulation and perception of perceivers. Viewing communication as a complex of inadvertent and derived traits facilitates understanding of the selective pressures shaping communication and those shaping information and its reliability. This viewpoint further contributes to resolving the current controversy on the role of information in communication.

    2001-01-01

    Next-generation Mars communications networks will provide communications and navigation services to a wide variety of Mars science vehicles including: spacecraft that are arriving at Mars, spacecraft that are entering and descending in the Mars atmosphere, scientific orbiter spacecraft, spacecraft that return Mars samples to Earth, landers, rovers, aerobots, airplanes, and sensing pods. In the current architecture plans, the communication services will be provided using capabilities deployed on the science vehicles as well as dedicated communication satellites that will together make up the Mars network. This network will evolve as additional vehicles arrive, depart or end their useful missions. Cost savings and increased reliability will result from the ability to share communication services between missions. This paper discusses the basic architecture that is needed to support the Mars Communications Network part of NASA's Space Science Enterprise (SSE) communications architecture. The network may use various networking technologies such as those employed in the terrestrial Internet, as well as special purpose deep-space protocols to move data and commands autonomously between vehicles, at disparate Mars vicinity sites (on the surface or in near-Mars space) and between Mars vehicles and earthbound users. The architecture of the spacecraft on-board local communications is being reconsidered in light of these new networking requirements. The trend towards increasingly autonomous operation of the spacecraft is aimed at reducing the dependence on resource scheduling provided by Earth-based operators and increasing system fault tolerance. However, these benefits will result in increased communication and software development requirements. As a result, the envisioned Mars communications infrastructure requires both hardware and protocol technology advancements. This paper will describe a number of the critical technology needs and some of the ongoing research

    This paper briefly introduces a concept for low-cost, global, day-night, all-weather disaster warning and assistance. Evolving, advanced space technology with passive radio frequency reflectors in conjunction with an imaging synthetic aperture radar is employed to detect, identify, locate, and provide passive communication with earth users in distress. This concept evolved from a broad NASA research on new global search and rescue techniques. Appropriate airborne radar test results from this research are reviewed and related to potential disaster applications. The analysis indicates the approach has promise for disaster communications relative to floods, droughts, earthquakes, volcanic eruptions, and severe storms.

    Smart grid is an intelligent electricity grid system. A reliable two-way communication system is required to transmit both critical and non-critical smart grid data. However, it is difficult to locate a huge chunk of dedicated spectrum for smart grid communications. Hence, cognitive radio based communication is applied. Cognitive radio allows smart grid users to access licensed spectrums opportunistically with the constraint of not causing harmful interference to licensed users. In this paper, a cognitive radio based smart grid communication framework is proposed. Smart grid framework consists of Home Area Network (HAN) and Advanced Metering Infrastructure (AMI), while AMI is made up of Neighborhood Area Network (NAN) and Wide Area Network (WAN). In this paper, the authors only report the findings for AMI communication. AMI is smart grid domain that comprises smart meters, data aggregator unit, and billing center. Meter data are collected by smart meters and transmitted to data aggregator unit by using cognitive 802.11 technique; data aggregator unit then relays the data to billing center using cognitive WiMAX and TV white space. The performance of cognitive radio in AMI communication is investigated using Network Simulator 2. Simulation results show that cognitive radio improves the latency and throughput performances of AMI. Besides, cognitive radio also improves spectrum utilization efficiency of WiMAX band from 5.92% to 9.24% and duty cycle of TV band from 6.6% to 10.77%.

    Breslau, Joshua; Engel, Charles C.

    2016-01-01

    Abstract The dramatic evolution in information and communication technologies (ICTs) online and on smartphones has led to rapid innovations in behavioral health care. To assist the U.S. Air Force in developing a strategy for use of ICTs, the authors reviewed the scientific literature on their use to prevent and treat behavioral health conditions, such as major depression, posttraumatic stress disorder, and alcohol misuse. There is currently little scientific evidence supporting additional investment in ICT-based psychosocial programs for resilience or prevention of posttraumatic stress symptoms, depression, or anxiety. Instead, preventive interventions might prioritize problems of alcohol misuse and intimate partner violence. ICT applications that play a role in the treatment process may be used for patient education and activation, to improve decisionmaking by clinicians, to provide a therapy, to improve adherence to treatment, or to maintain treatment gains over time. However, partly due to the rapid pace of development of the technology, there is little or no evidence in the literature regarding the efficacy of the most recently developed types of ICTs, in particular those using smartphones. Despite the lack of solid research evidence to date, ICTs hold promise in addressing the challenges of mental health care. One promising avenue is development of reliable methods for patient-clinician communication between therapy sessions; another is Internet-based cognitive behavioral therapy. The authors recommend that the Air Force should take an incremental approach to adopting the use of ICTs—one that involves a program of measurement-based implementation and process and outcome monitoring rather than urgent dissemination.

    1999-01-01

    The Advanced Communications Technology Satellite (ACTS) was conceived at the National Aeronautics and Space Administration (NASA) in the late 1970's as a follow-on program to ATS and CTS to continue NASA's long history of satellite communications projects. The ACTS project set the stage for the C-band satellites that started the industry, and later the ACTS project established the use of Ku-band for video distribution and direct-to-home broadcasting. ACTS, launched in September 1993 from the space shuttle, created a revolution in satellite system architecture by using digital communications techniques employing key technologies such as a fast hopping multibeam antenna, an on-board baseband processor, a wide-band microwave switch matrix, adaptive rain fade compensation, and the use of 900 MHz transponders operating at Ka-band frequencies. This paper describes the lessons learned in each of the key ACTS technology areas, as well as in the propagation investigations.

  6. Advanced technology for space communications and tracking systems

    NASA Astrophysics Data System (ADS)

    Krishen, Kumar

    The communications needs for the Growth Space Station (GSS) are envisioned to drive NASA to seek unique concepts and capability to establish this permanent presence in space. Furthermore, it will provide a facility to assemble, test, and deploy rather large and unique communications systems/subsystems. GSS is envisioned to need or desire the capability to communicate with many more satellites and spacecraft than the initial operating capability (IOC). The increased interconnectivity will include links with numerous NASA and other U.S. Government satellites, commercial satellites, foreign spacecraft, and deep space missions. In parallel, the payloads/experiments on Space Station are expected to increase in numbers and in terms of data gathering capabilities. The use of automation and robotics will require high data rate and extremely reliable links. The GSS will need to accommodate continually evolving and largely unknown future requirements for coverage, data rates, number of users, etc. This requirement for flexibility over a long term will provide a unique challenge to develop systems which are user transparent and which are quickly reconfigurable. Deep space communications are driven by the relatively near-term envisioned missions to the Moon and Mars. In addition to these, projected NASA missions include Saturn, Uranus, Neptune, and comet/asteroid probes. These future deep space missions will require highly reliable, long life, and very efficient communications and tracking systems to ensure success. Additionally, for space proximity operations, systems capable of supporting rendezvous, station keeping, and soft docking between various vehicles, Shuttle, satellites, unknown objects, and Space Stations are needed. In this paper, technology advancements in the communications and tracking areas being pursued within NASA, as applicable to future missions and associated space operations, are presented. The relevance of optical-, laser-, and millimeter-wave based

  13. Engaging Patients with Advance Directives using an Information Visualization Approach

    PubMed Central

    Woollen, Janet; Bakken, Suzanne

    2016-01-01

    Despite the benefits of advance directives (AD) to both patients and care providers, they are often not completed due to lack of patient awareness. The purpose of this paper is to advocate for creation and use of an innovative information visualization (infovisual) as a health communication tool aimed at improving AD dissemination and engagement. The infovisual would promote AD awareness by engaging patients to learn about their options and inspire contemplation and conversation regarding patients’ end-of-life (EOL) journey. An infovisual may be able to communicate insights that are often communicated in words, but are much more powerfully communicated by example. Furthermore, an infovisual could facilitate vivid understanding of options and inspire the beginning of often-difficult conversations between care providers, patients and loved ones. It may also save clinicians’ time, as care providers may be able to spend less time explaining details of EOL care options. Use of an infovisual could assist in ensuring a well-planned EOL.

  14. Citizen perceptions of information flow around a nuclear facility: A study in risk communication

    SciTech Connect

    Price, M.O.

    1997-08-01

    Responses of focus group members from the region around a Nuclear Facility provide the data for this qualitative study concerning citizen perceptions of available site information. Analyses of three of the focus group discussion questions and the answers they elicited showed a dominant perception among participants of insufficient easily available information about the site. These respondents also indicated that most of them obtain site information through mass media and hearsay, that many lack trust in the information they have and would trust only an independent entity to provide accurate information. A new area in communication studies, variously called environmental risk communication, risk communication and health risk communication, continues to evolve among those working in various allied disciplines, some far removed from communication. As science attempts to solve environmental problems caused by technological advances, this field acquires numerous practitioners. Some of these risk communication experts may however, be overlooking basic and necessary components of effective communication, because their expertise is in another discipline. One result of this can be communication breakdown in which those involved, assume that meaning is shared, when in fact the opposite is true. This paper seeks to clarify a necessary ingredient of effective interpersonal risk communication, using data obtained from citizens living around one of the nation`s nuclear facilities as an example.

    1994-01-01

    A communications experiment is described as a link between the Space Shuttle Orbiter (SSO) and the Advanced Communications Technology Satellite (ACTS). Breadboarding for this experiment has led to two items with potential for commercial application: a 1-Watt Ka-band amplifier and a Ka-band, circularly polarized microstrip antenna. Results of the hybrid Ka-band amplifier show gain at 30 dB and a saturated output power of 28.5 dBm. A second version comprised of MMIC amplifiers is discussed. Test results of the microstrip antenna subarray show a gain of approximately 13 dB and excellent circular polarization.

  18. A secure and robust information hiding technique for covert communication

    The unprecedented advancement of multimedia and growth of the internet has made it possible to reproduce and distribute digital media easier and faster. This has given birth to information security issues, especially when the information pertains to national security, e-banking transactions, etc. The disguised form of encrypted data makes an adversary suspicious and increases the chance of attack. Information hiding overcomes this inherent problem of cryptographic systems and is emerging as an effective means of securing sensitive data being transmitted over insecure channels. In this paper, a secure and robust information hiding technique referred to as Intermediate Significant Bit Plane Embedding (ISBPE) is presented. The data to be embedded is scrambled and embedding is carried out using the concept of Pseudorandom Address Vector (PAV) and Complementary Address Vector (CAV) to enhance the security of the embedded data. The proposed ISBPE technique is fully immune to Least Significant Bit (LSB) removal/replacement attack. Experimental investigations reveal that the proposed technique is more robust to various image processing attacks like JPEG compression, Additive White Gaussian Noise (AWGN), low pass filtering, etc. compared to conventional LSB techniques. The various advantages offered by ISBPE technique make it a good candidate for covert communication.

    Novel approach enables high-speed special-purpose processors Advanced reconfigurable and reprogrammable communication systems will require sub-130-nanometer electronics. Legacy single event upset (SEU) radiation-tolerant circuits are ineffective at speeds greater than 125 megahertz. In Phase I of this project, ICs, LLC, demonstrated new base-level logic circuits that provide SEU immunity for sub-130-nanometer high-speed circuits. In Phase II, the company developed an innovative self-restoring logic (SRL) circuit and a system approach that provides high-speed, SEU-tolerant solutions that are effective for sub-130-nanometer electronics scalable to at least 22-nanometer processes. The SRL system can be used in the design of NASA's next-generation special-purpose processors, especially reconfigurable communication processors.

    Important advances are being made in the fight against communicable diseases by using new digital tools. While they can be a challenge to deploy at-scale, GPS-enabled smartphones, electronic dashboards and computer models have multiple benefits. They can facilitate program operations, lead to new insights about the disease transmission and support strategic planning. Today, tools such as these are used to vaccinate more children against polio in Nigeria, reduce the malaria burden in Zambia and help predict the spread of the Ebola epidemic in West Africa.

  1. In backyards, on front lawns: examining informal risk communication and communicators.

    PubMed

    Rickard, Laura N

    2011-09-01

    Risk communicators are often envisioned as government officials, public relations practitioners, or health workers. Yet much of the public's risk information comes from informal messages and unofficial carriers. Referred to in this study as "informal risk communicators" (IRCs), these individuals are often service workers who relay risk information to public audiences, though often outside of their formal job descriptions. Literatures in the health communication, science and technology studies, and risk communication fields have considered ideas relevant to explaining these individuals, and the risk communication work they perform. To further explore this category of individuals, this study examines the communicative practices of commercial pesticide applicators, using both in-depth interviews and surveys. Through their interactions with clients, these individuals offer care, as well as project expertise and identity; however, the extent to which this work is recognized and validated is less clear. Both applied and theoretical implications of this research are considered.

    This paper discusses the attributes of the Advanced Information Technology (AIT) tool set, a database application builder designed at the Lawrence Livermore National Laboratory. AIT consists of a C library and several utilities that provide referential integrity across a database, interactive menu and field level help, and a code generator for building tightly controlled data entry support. AIT also provides for dynamic menu trees, report generation support, and creation of user groups. Composition of the library and utilities is discussed, along with relative strengths and weaknesses. In addition, an instantiation of the AIT tool set is presented using a specific application. Conclusions about the future and value of the tool set are then drawn based on the use of the tool set with that specific application.

    1995-01-01

    The current generation of communications satellites are located primarily in geosynchronous Earth orbit (GEO). Over the next decade, however, a new generation of communications satellites will be built and launched, designed to provide a world-wide interconnection of portable telephones. For this mission, the satellites must be positioned in lower polar and near-polar orbits. To provide complete coverage, large numbers of satellites will be required. Because the required number of satellites decreases as the orbital altitude is increased, fewer satellites would be required if the orbit chosen were raised from low to intermediate orbit. However, in intermediate orbits, satellites encounter significant radiation due to trapped electrons and protons. Radiation tolerant solar cells may be necessary to make such satellites feasible. We analyze the amount of radiation encountered in low and intermediate polar orbits at altitudes of interest to next-generation communication satellites, calculate the expected degradation for silicon, GaAs, and InP solar cells, and show that the lifetimes can be significantly increased by use of advanced solar cells.

  14. Natural language processing and advanced information management

    NASA Technical Reports Server (NTRS)

    Hoard, James E.

    1989-01-01

    Integrating diverse information sources and application software in a principled and general manner will require a very capable advanced information management (AIM) system. In particular, such a system will need a comprehensive addressing scheme to locate the material in its docuverse. It will also need a natural language processing (NLP) system of great sophistication. It seems that the NLP system must serve three functions. First, it provides an natural language interface (NLI) for the users. Second, it serves as the core component that understands and makes use of the real-world interpretations (RWIs) contained in the docuverse. Third, it enables the reasoning specialists (RSs) to arrive at conclusions that can be transformed into procedures that will satisfy the users' requests. The best candidate for an intelligent agent that can satisfactorily make use of RSs and transform documents (TDs) appears to be an object oriented data base (OODB). OODBs have, apparently, an inherent capacity to use the large numbers of RSs and TDs that will be required by an AIM system and an inherent capacity to use them in an effective way.

    2012-01-01

    The use of the telephone for providing health care is growing. A significant amount of social meaning is derived from visual information, and the absence of visual stimuli provides unique barriers to communication and increases the risks for misunderstandings and distractions. Understanding challenges to telephone communication can provide insight into training opportunities for overcoming these difficulties and improving patient care. The purpose of this research was to explore through focus groups the challenges of phone communication perceived by specialists in poison information. General types of challenges to effective phone communication included developing new communication skills to compensate for lack of visual information, difficulty assessing caller understanding, difficulty managing caller misunderstandings, maintaining distinctive assessments for routine calls, and managing the multifaceted aspects of job stress. The desire for training to enhance telehealth and cultural competency skills was also mentioned, and these findings might provide guidance for the development of training opportunities for telehealth professionals.

    The aim of this investigation was to conduct a comprehensive examination of communication between parents and health care professionals (HCPs) in the pediatric intensive care unit (PICU). A secondary analysis was performed on data from 3 previous qualitative studies, which included 30 physicians, 37 nurses, and 38 parents in France and Quebec (Canada). All three studies examined a mix of cases where children either survived or died. All data referring to communication between parents (and patients when applicable) and HCPs were examined to identity themes that related to communication. Thematic categories for parents and HCPs were developed. Three interrelated dimensions of communication were identified: (1) informational communication, (2) relational communication, and (3) communication and parental coping. Specific themes were identified for each of these 3 dimensions in relation to parental concerns as well as HCP concerns. This investigation builds on prior research by advancing a comprehensive analysis of PICU communication that includes (a) cases where life-sustaining treatments were withdrawn or withheld as well as cases where they were maintained, (b) data from HCPs as well as parents, and (c) investigations conducted in 4 different sites. An evidence-informed conceptual framework is proposed for PICU communication between parents and HCPs. We also outline priorities for the development of practice, education, and research.

    2010-06-01

    Autism spectrum disorders (ASD) affect approximately 1 in 150 children across the U.S., and are characterized by abnormal social actions, language difficulties, repetitive or restrictive behaviors, and special interests. ASD include autism (autistic disorder), Asperger Syndrome, and Pervasive Developmental Disorder not otherwise specified (PDD-NOS or atypical autism). High-functioning individuals may communicate with moderate-to-high language skills, although difficulties in social skills may result in communication deficits. Low-functioning individuals may have severe deficiencies in language, resulting in poor communication between the individual and others. Behavioral intervention programs have been developed for ASD, and are frequently adjusted to accommodate specific individual needs. Many of these programs are school-based and aim to support the child in the development of their skills, for use outside the classroom with family and friends. Strides are being made in understanding the factors contributing to the development of ASD, particularly the genetic contributions that may underlie these disorders. Mutant mouse models provide powerful research tools to investigate the genetic factors associated with ASD and its co-morbid disorders. In support, the BTBR T+tf/J mouse strain incorporates ASD-like social and communication deficits and high levels of repetitive behaviors. This commentary briefly reviews the reciprocal relationship between observations made during evidence-based behavioral interventions of high- versus low-functioning children with ASD and the accumulating body of research in autism, including animal studies and basic research models. This reciprocity is one of the hallmarks of the scientific method, such that research may inform behavioral treatments, and observations made during treatment may inform subsequent research.

    2011-01-01

    We address how information developed and effectively communicated through community based participatory research (CBPR) can reverse long-standing information disparities, empower a community, and be an agent for sustained change. Substantial information and power disparities existed between the polluted community and both the pollution industry and governmental regulators. An environmental justice partnership between a local community organization, physicians, and university performed CBPR and then developed a novel communication strategy to address a series of information disparities around a local water pollution issue. The community established a set of principles to govern the communication of results as soon as they were determined to be scientifically valid, including informing study participants and the community before other interested parties. CBPR results combined with a community-first communication strategy reversed the preexisting information disparities. The novel communication flow reversed the preferential information flow to industry and government associated with the usual scientific publication process. The community was empowered, and industry and government agencies responded positively to study recommendations. The CBPR results together with community first communication led to adoption of both community-wide and individual solutions and provided powerful motivation for behavioral change by industry and residents.

    NASA Technical Reports Server (NTRS)

    Choung, Youn H.; Stiles, W. Herschel; Wu, Joseph; Wong, William C.; Chen, C. Harry

    1986-01-01

    The design of the Advanced Communications Technology Satellite MBA system, which provides both spot beam and scanning beam coverage to both high and low burst rates data-users is examined. The MBA consists of receive and transmit antennas installed on a common precision mounting platform that is integrated to the bus through three flexures; a lightweight system with low thermal distortion is obtained by using composite materials for the MBA structures. The RF design, which is a Cassegrain reflector with a large equivalent focal length/aperture size, is described. Consideration is given to the position of the feed in order to minimize scan loss and sidelobe levels, the size of the subreflector in order to minimize feed spillover, and antenna performance degradation caused by reflector surface distortion. Breadbroad model test result reveal that the maximum sidelobe level outside the 2.5 HPBW region is -30 dB or lower relative to the power.

    2000-01-01

    The Advanced Communications Satellite (ACTS) was conceived and developed in the mid- 1980s as an experimental satellite to demonstrate unproven Ka-band technology, and potential new commercial applications and services. Since launch into geostationary orbit in September 1993. ACTS has accumulated almost seven years of essentially trouble-free operation and met all program objectives. The unique technology, service experiments. and system level demonstrations accomplished by ACTS have been reported in many forums over the past several years. As ACTS completes its final experiments activity, this paper will relate the top-level program goals that have been achieved in the design, operation, and performance of the particular satellite subsystems. Pre-launch decisions to ensure satellite reliability and the subsequent operational experiences contribute to lessons learned that may be applicable to other comsat programs.

    McElroy, David R.; Kolba, Dean P.; Greenberg, William L.; Semprucci, Marilyn

    1993-02-01

    The communications capabilities provided by EHF satellites can range from low data rate services (75 to 2400 bps per channel) to medium data rate links (4.8 kbps to 1.544 Mbps per link) depending on the payload configuration. Through the use of EHF waveform standards, the EHF payloads will be compatible with existing and planned EHF terminals. Advanced technologies permit the development of highly capable, lightweight payloads which can be utilized in a variety of roles. The key payload technologies include adaptive uplink antennas; high speed, low power digital signal processing subsystems; lightweight frequency hopping synthesizers; and efficient solid-state transmitters. The focus in this paper is on the signal processing and frequency generation technologies and their application in a lightweight EHF payload for tactical applications.

    NASA Technical Reports Server (NTRS)

    1988-01-01

    This applications guide first surveys the capabilities of the Advanced Communication Technology Satellite (ACTS) system (both the flight and ground segments). This overview is followed by a description of the baseband processor (BBP) and microwave switch matrix (MSM) operating modes. Terminals operating with the baseband processor are referred to as low burst rate (LBR); and those operating with the microwave switch matrix, as high burst rate (HBR). Three very small-aperture terminals (VSATs), LBR-1, LBR-2, and HBR, are described for various ACTS operating modes. Also described is the NASA Lewis link evaluation terminal. A section on ACTS experiment opportunities introduces a wide spectrum of network control, telecommunications, system, and scientific experiments. The performance of the VSATs is discussed in detail. This guide is intended as a catalyst to encourage participation by the telecommunications, business, and science communities in a broad spectrum of experiments.

  15. Reducing Diagnostic Errors through Effective Communication: Harnessing the Power of Information Technology

    2008-01-01

    Diagnostic errors are poorly understood despite being a frequent cause of medical errors. Recent efforts have aimed to advance the "basic science" of diagnostic error prevention by tracing errors to their most basic origins. Although a refined theory of diagnostic error prevention will take years to formulate, we focus on communication breakdown, a major contributor to diagnostic errors and an increasingly recognized preventable factor in medical mishaps. We describe a comprehensive framework that integrates the potential sources of communication breakdowns within the diagnostic process and identifies vulnerable steps in the diagnostic process where various types of communication breakdowns can precipitate error. We then discuss potential information technology-based interventions that may have efficacy in preventing one or more forms of these breakdowns. These possible intervention strategies include using new technologies to enhance communication between health providers and health systems, improve patient involvement, and facilitate management of information in the medical record.

    1996-01-01

    This paper describes a program of experiments conducted over the advanced communications technology satellite (ACTS) and the associated TI-VSAT (very small aperture terminal). The experiments were motivated by the commercial potential of low-cost receive only satellite terminals that can operate in a hybrid network environment, and by the desire to demonstrate frame relay technology over satellite networks. The first experiment tested highly adaptive methods of satellite bandwidth allocation in an integrated voice-data service environment. The second involved comparison of forward error correction (FEC) and automatic repeat request (ARQ) methods of error control for satellite communication with emphasis on the advantage that a hybrid architecture provides, especially in the case of multicasts. Finally, the third experiment demonstrated hybrid access to databases and compared the performance of internetworking protocols for interconnecting local area networks (LANs) via satellite. A custom unit termed frame relay access switch (FRACS) was developed by COMSAT Laboratories for these experiments; the preparation and conduct of these experiments involved a total of 20 people from the University of Maryland, the University of Colorado and COMSAT Laboratories, from late 1992 until 1995.

    The ACTS experiments program, which began in December 1993 and consisted of 103 different experiments, has made significant contributions to minimizing the risk of advanced satellite communications technology. The ACTS Conference 2000 (AC2000) was held to report the results of the program since the last ACTS conference was held in 1995 and to celebrate the end of a very successful satellite program. The conference was held on May 31, 2000, as part of the 6th Ka-band Utilization Conference in Cleveland, Ohio. Approximately 280 representatives of industry, academia, and government attended. The conference was organized into two parts: a technical session during the day and an evening reception. During the day, a series of five technical sessions included presentations of 17 papers covering the results of the experiment activity and technical performance of the satellite. In the evening, a reception was held to celebrate the end of the ACTS Experiments Program on one of NASA's most successful experimental communications satellite. These proceedings were developed to capture the entire event, including the evening reception.

  18. Communicating genetic risk information within families: a review.

    PubMed

    Wiseman, Mel; Dancyger, Caroline; Michie, Susan

    2010-12-01

    This review of family communication of genetic risk information addresses questions of what the functions and influences on communication are; what, who and how family members are told about genetic risk information; what the impact for counsellee, relative and relationships are; whether there are differences by gender and condition; and what theories and methodologies are used. A systematic search strategy identified peer-reviewed journal articles published 1985-2009 using a mixture of methodologies. A Narrative Synthesis was used to extract and summarise data relevant to the research questions. This review identified 33 articles which found a consistent pattern of findings that communication about genetic risk within families is influenced by individual beliefs about the desirability of communicating genetic risk and by closeness of relationships within the family. None of the studies directly investigated the impact of communication on counsellees or their families, differences according to gender of counsellee or by condition nor alternative methods of communication with relatives. The findings mainly apply to late onset conditions such as Hereditary Breast and Ovarian Cancer. The most frequently used theory was Family Systems Theory and methods were generally qualitative. This review points to multifactorial influences on who is communicated with in families and what they are told about genetic risk information. Further research is required to investigate the impact of genetic risk information on family systems and differences between genders and conditions.

  20. Communicating genetic information: a difficult challenge for future pediatricians

    PubMed Central

    2007-01-01

    Background The role of the pediatrician as genetic counselor is ideal because pediatricians have medical knowledge and experience with genetic disorders (e.g. Down syndrome). Moreover, pediatricians can provide comprehensive care in a medical home to patients with genetic disorders. However, changes in the curriculum of the pediatric resident are necessary to address the future challenges of effectively communicating genetic information to patients. The objective of this study was to explore these challenges and make recommendations for training to adequately prepare pediatricians for their future role as genetic counselors. Methods Three reviewers independently searched PubMed, OVID, and Medline databases to identify articles describing the challenges of communicating genetic information to patients, published from 1960 to December 2005. After the publications were identified and reviewed, four major areas of interest were identified in order to categorize the findings. Results Twenty-five publications were identified during the literature search. From the review, the following categories were selected to organize the findings: (1) Inherent difficulties of communicating and comprehending genetic information; (2) Comprehension of genetic information by pediatricians; (3) Genetics training in residency programs; and (4) The effect of genetic information on the future role of pediatricians and potential legal implications. Conclusion Pediatricians and residents lack essential knowledge of genetics and communication skills for effective counseling of patients. The review indicated that successful communication of genetic information involves a number of important skills and considerations. It is likely that these skills and considerations are universally required for the communication of most complex specialized medical information. In the past, communication skills have not been considered a priority. Today, these skills have become a demanding professional and even

  1. Communication and decision support for children with advanced cancer and their families.

    PubMed

    Mack, Jennifer W; Feudtner, Chris; Hinds, Pamela S

    2012-01-01

    Clinician communication related to treatment decision making is a fundamentally important health care intervention and is often reported by parents of seriously ill children to be the most valued of clinician skills. Since different children and families have different communication styles and expectations, and since these may change over the course of the illness experience, one of the early and recurring tasks is to clarify and work with these diverse styles and expectations. Adopting a stance of compassionate desire to know more about patients and families, in addition to imparting information, is vital, and can be facilitated by following a general strategy of "ask, tell, ask." In addition to the exchange of information, communication between clinician and patient and family also involves the signaling and exchange of emotions, in which the pace, verbal inflection, and body language of the conversation are fundamental. Discussions about prognosis and goals of care, while needing to be handled in a gentle manner, should start early in the illness experience and be revised whenever there is a relapse or major complication. Children often want to participate in these conversations to a degree of their own choosing, which they themselves can clarify. Effective and empathetic clinician communication can greatly facilitate decision making and care for children with advanced cancer and their families, and provide a substantial source of comfort.

  2. Reinforcing Visual Grouping Cues to Communicate Complex Informational Structure.

    PubMed

    Bae, Juhee; Watson, Benjamin

    2014-12-01

    In his book Multimedia Learning [7], Richard Mayer asserts that viewers learn best from imagery that provides them with cues to help them organize new information into the correct knowledge structures. Designers have long been exploiting the Gestalt laws of visual grouping to deliver viewers those cues using visual hierarchy, often communicating structures much more complex than the simple organizations studied in psychological research. Unfortunately, designers are largely practical in their work, and have not paused to build a complex theory of structural communication. If we are to build a tool to help novices create effective and well structured visuals, we need a better understanding of how to create them. Our work takes a first step toward addressing this lack, studying how five of the many grouping cues (proximity, color similarity, common region, connectivity, and alignment) can be effectively combined to communicate structured text and imagery from real world examples. To measure the effectiveness of this structural communication, we applied a digital version of card sorting, a method widely used in anthropology and cognitive science to extract cognitive structures. We then used tree edit distance to measure the difference between perceived and communicated structures. Our most significant findings are: 1) with careful design, complex structure can be communicated clearly; 2) communicating complex structure is best done with multiple reinforcing grouping cues; 3) common region (use of containers such as boxes) is particularly effective at communicating structure; and 4) alignment is a weak structural communicator.

  6. Information transmission and recovery in neural communications channels

    SciTech Connect

    Eguia, M. C.; Rabinovich, M. I.; Abarbanel, H. D. I.

    2000-11-01

    Biological neural communications channels transport environmental information from sensors through chains of active dynamical neurons to neural centers for decisions and actions to achieve required functions. These kinds of communications channels are able to create information and to transfer information from one time scale to the other because of the intrinsic nonlinear dynamics of the component neurons. We discuss a very simple neural information channel composed of sensory input in the form of a spike train that arrives at a model neuron, then moves through a realistic synapse to a second neuron where the information in the initial sensory signal is read. Our model neurons are four-dimensional generalizations of the Hindmarsh-Rose neuron, and we use a model of chemical synapse derived from first-order kinetics. The four-dimensional model neuron has a rich variety of dynamical behaviors, including periodic bursting, chaotic bursting, continuous spiking, and multistability. We show that, for many of these regimes, the parameters of the chemical synapse can be tuned so that information about the stimulus that is unreadable at the first neuron in the channel can be recovered by the dynamical activity of the synapse and the second neuron. Information creation by nonlinear dynamical systems that allow chaotic oscillations is familiar in their autonomous oscillations. It is associated with the instabilities that lead to positive Lyapunov exponents in their dynamical behavior. Our results indicate how nonlinear neurons acting as input/output systems along a communications channel can recover information apparently ''lost'' in earlier junctions on the channel. Our measure of information transmission is the average mutual information between elements, and because the channel is active and nonlinear, the average mutual information between the sensory source and the final neuron may be greater than the average mutual information at an earlier neuron in the channel. This

  12. High security chaotic multiple access scheme for visible light communication systems with advanced encryption standard interleaving

    NASA Astrophysics Data System (ADS)

    Qiu, Junchao; Zhang, Lin; Li, Diyang; Liu, Xingcheng

    2016-06-01

    Chaotic sequences can be applied to realize multiple user access and improve the system security for a visible light communication (VLC) system. However, since the map patterns of chaotic sequences are usually well known, eavesdroppers can possibly derive the key parameters of chaotic sequences and subsequently retrieve the information. We design an advanced encryption standard (AES) interleaving aided multiple user access scheme to enhance the security of a chaotic code division multiple access-based visible light communication (C-CDMA-VLC) system. We propose to spread the information with chaotic sequences, and then the spread information is interleaved by an AES algorithm and transmitted over VLC channels. Since the computation complexity of performing inverse operations to deinterleave the information is high, the eavesdroppers in a high speed VLC system cannot retrieve the information in real time; thus, the system security will be enhanced. Moreover, we build a mathematical model for the AES-aided VLC system and derive the theoretical information leakage to analyze the system security. The simulations are performed over VLC channels, and the results demonstrate the effectiveness and high security of our presented AES interleaving aided chaotic CDMA-VLC system.

  13. Advances in high-speed low-latency communications for nanopositioning in advanced microscopy

    NASA Astrophysics Data System (ADS)

    Jordan, Scott C.

    2012-06-01

    We present a comparison of classical and recently developed communications interfacing technologies relevant to scanned imaging. We adopt an applications perspective, with a focus on interfacing techniques as enablers for enhanced resolution, speed, stability, information density or similar benefits. A wealth of such applications have emerged, ranging from nanoscale-stabilized force microscopy yielding 100X resolution improvement thanks to leveraging the latest in interfacing capabilities, to novel approaches in analog interfacing which improve data density and DAC resolution by several orders of magnitude. Our intent is to provide tools to understand, select and implement advanced interfacing to take applications to the next level. We have entered an era in which new interfacing techniques are enablers, in their own right, for novel imaging techniques. For example, clever leveraging of new interfacing technologies has yielded nanoscale stabilization and atomic-force microscopy (AFM) resolution enhancement. To assist in choosing and implementing interfacing strategies that maximize performance and enable new capabilities, we review available interfaces such as USB2, GPIB and Ethernet against the specific needs of positioning for the scanned-imaging community. We spotlight recent developments such as LabVIEW FPGA, which allows non-specialists to quickly devise custom logic and interfaces of unprecedentedly high performance and parallelism. Notable applications are reviewed, including a clever amalgamation of AFM and optical tweezers and a picometer-scaleaccuracy interferometer devised for ultrafine positioning validation. We note the Serial Peripheral Interface (SPI), emerging as a high-speed/low-latency instrumentation interface. The utility of instrument-specific parallel (PIO) and TTL sync/trigger (DIO) interfaces is also discussed. Requirements of tracking and autofocus are reviewed against the time-critical needs of typical applications (to avoid, for example

    NASA Astrophysics Data System (ADS)

    2011-02-01

    We present ongoing research in the application of information theory to animal communication systems with the goal of developing additional detectors and estimators for possible extraterrestrial intelligent signals. Regardless of the species, for intelligence (i.e., complex knowledge) to be transmitted certain rules of information theory must still be obeyed. We demonstrate some preliminary results of applying information theory to socially complex marine mammal species (bottlenose dolphins and humpback whales) as well as arboreal squirrel monkeys, because they almost exclusively rely on vocal signals for their communications, producing signals which can be readily characterized by signal analysis. Metrics such as Zipf's Law and higher-order information-entropic structure are emerging as indicators of the communicative complexity characteristic of an "intelligent message" content within these animals' signals, perhaps not surprising given these species' social complexity. In addition to human languages, for comparison we also apply these metrics to pulsar signals—perhaps (arguably) the most "organized" of stellar systems—as an example of astrophysical systems that would have to be distinguished from an extraterrestrial intelligence message by such information theoretic filters. We also look at a message transmitted from Earth (Arecibo Observatory) that contains a lot of meaning but little information in the mathematical sense we define it here. We conclude that the study of non-human communication systems on our own planet can make a valuable contribution to the detection of extraterrestrial intelligence by providing quantitative general measures of communicative complexity. Studying the complex communication systems of other intelligent species on our own planet may also be one of the best ways to deprovincialize our thinking about extraterrestrial communication systems in general.

    This two part study examines the communication requirements to provide weather information in the cockpit as well as public and private communication systems available to address the requirements. Ongoing research projects combined with user needs for weather related information are used to identify and describe potential weather products that address decision support in three time frames: Far-Term Strategic, Near-Term Strategic and Tactical. Data requirements of these future products are identified and quantified. Communications systems and technologies available in the public as well as private sector are analyzed to identify potential solutions. Recommendations for further research identify cost, performance, and safety benefits to justify the investment. The study concludes that not all weather information has the same level of urgency to safety-of-flight and some information is more critical to one category of flight than another. Specific weather products need to be matched with communication systems with appropriate levels of reliability to support the criticality of the information. Available bandwidth for highly critical information should be preserved and dedicated to safety. Meanwhile, systems designed for in-flight-entertainment and other passenger/crew services could be used to support less critical information that is used only for planning and economic decision support.

    The implementation of electrical and IT infrastructure systems at the North Carolina Center for Automotive Research , Inc. (NCCAR) has achieved several key objectives in terms of system functionality, operational safety and potential for ongoing research and development. Key conclusions include: (1) The proven ability to operate a high speed wireless data network over a large 155 acre area; (2) Node to node wireless transfers from access points are possible at speeds of more than 50 mph while maintaining high volume bandwidth; (3) Triangulation of electronic devices/users is possible in areas with overlapping multiple access points, outdoor areas with reduced overlap of access point coverage considerably reduces triangulation accuracy; (4) Wireless networks can be adversely affected by tree foliage, pine needles are a particular challenge due to the needle length relative to the transmission frequency/wavelength; and (5) Future research will use the project video surveillance and wireless systems to further develop automated image tracking functionality for the benefit of advanced vehicle safety monitoring and autonomous vehicle control through 'vehicle-to-vehicle' and 'vehicle-to-infrastructure' communications. A specific advantage realized from this IT implementation at NCCAR is that NC State University is implementing a similar wireless network across Centennial Campus, Raleigh, NC in 2011 and has benefited from lessons learned during this project. Consequently, students, researchers and members of the public will be able to benefit from a large scale IT implementation with features and improvements derived from this NCCAR project.

    1996-01-01

    The advanced communication technology satellite (ACTS) gigabit satellite network provides long-haul point-to-point and point-to-multipoint full-duplex SONET services over NASA's ACTS. at rates up to 622 Mbit/s (SONET OC-12), with signal quality comparable to that obtained with terrestrial fiber networks. Data multiplexing over the satellite is accomplished using time-division multiple access (TDMA) techniques coordinated with the switching and beam hopping facilities provided by ACTS. Transmissions through the satellite are protected with Reed-Solomon encoding. providing virtually error-free transmission under most weather conditions. Unique to the system are a TDMA frame structure and satellite synchronization mechanism that allow: (a) very efficient utilization of the satellite capacity: (b) over-the-satellite dosed-loop synchronization of the network in configurations with up to 64 ground stations: and (c) ground station initial acquisition without collisions with existing signalling or data traffic. The user interfaces are compatible with SONET standards, performing the function of conventional SONET multiplexers and. as such. can be: readily integrated with standard SONET fiber-based terrestrial networks. Management of the network is based upon the simple network management protocol (SNMP). and includes an over-the-satellite signalling network and backup terrestrial internet (IP-based) connectivity. A description of the ground stations is also included.

    The aim of this study was to investigate the influence of information and communication technology use and skills on nursing performance. Questionnaires were prepared relating to using the technology, practical skills in utilizing information, the Six-Dimension Scale of Nursing Performance, and demographics. In all, 556 nurses took part (response rate, 72.6%). A two-way analysis of variance was used to determine the influence of years of nursing experience on the relationship between nursing performance and information and communication technology use. The results showed that the group possessing high technological skills had greater nursing ability than the group with low skills; the level of nursing performance improved with years of experience in the former group, but not in the latter group. Regarding information and communication technology use, the results showed that nursing performance improved among participants who used computers for sending and receiving e-mails, but it decreased for those who used cell phones for e-mail. The results suggest that nursing performance may be negatively affected if information and communication technology are inappropriately used. Informatics education should therefore be provided for all nurses, and it should include information use relating to cell phones and computers.

    Three experiments explore several factors which influence information transmission when warning messages are passed from person to person. In Experiment 1, messages were passed down chains of participants using five different modes of communication. Written communication channels resulted in more accurate message transmission than verbal. In addition, some elements of the message endured further down the chain than others. Experiment 2 largely replicated these effects and also demonstrated that simple repetition of a message eliminated differences between written and spoken communication. In a final field experiment, chains of participants passed information however they wanted to, with the proviso that half of the chains could not use telephones. Here, the lack of ability to use a telephone did not affect accuracy, but did slow down the speed of transmission from the recipient of the message to the last person in the chain. Implications of the findings for crisis and emergency risk communication are discussed.

  7. Basic limits on protocol information in data communications networks

    Gallager, R. G.

    1976-01-01

    The paper considers basic limitations on the amount of protocol information that must be transmitted in a data communication network to keep track of source and receiver addresses and of the starting and stopping of messages. Assuming Poisson message arrivals between each communicating source-receiver pair, a lower bound is found on the required protocol information for message. This lower bound is the sum of two terms, one for the message-length information, which depends only on the distribution of message lengths, and the other for the message-start information, which depends only on the product of the source-receiver pair arrival rate and the expected delay for transmitting the message. Two strategies are developed which, in the limit of large numbers of sources and receivers, almost meet the lower bound on protocol information.

    2002-11-01

    Use of information and communication technology (ICT) is rapidly increasing in medical and dental education. The aim of the present study was to determine the knowledge, skills and opinions of dental undergraduate students regarding ICT and to analyze possible shifts in the acquisition of these resources. For these purposes a survey of all undergraduate dental students at the University of Oulu, Finland, was conducted during the spring term 2000. All the students in the 5 years of study (n = 140) were asked to answer a questionnaire presented during a lecture or demonstration. An overall response rate of 95% was achieved. The frequencies and percentage distributions of the items were analyzed separately for each year (1-5). All the students in the faculty are provided with personal e-mail addresses at the beginning of their studies and special emphasis has been laid on the utilization of their ICT knowledge and skills. An overwhelming majority of the students, more than 95%, judged themselves to have good or satisfactory skills in word processing, but only a slight majority considered that they could manage some advanced operating system functions. Use of ICT services was high, as about 60% of the students used e-mail and one-third WWW services daily. Literature retrieval was widely employed, so that almost 80% of the students had used literature databases (including Ovid Medline and collections of electronic full-text articles), which were introduced and provided by the Medical Library when the students were in their second year. More than 50% had received educational material in electronic form often or sometimes, and almost 80% had communicated by e-mail with a faculty teacher. A clear trend (P < 0.05) was found for the younger students to use ICT services in general and for educational purposes more often than the older ones. In conclusion, e-mail and WWW have been widely adopted for both private and educational purposes by dental students in Finland and are

    Over the last six years since University Hospital opened, the University Hospital Information System (UHIS) has continued to evolve to what is today an advanced administrative and clinical information system. At University Hospital UHIS is the way of conducting business. A wide range of patient care applications are operational including Patient Registration, ADT for Inpatient/Outpatient/Emergency Room visits, Advanced Order Entry/Result Reporting, Medical Records, Lab Automated Data Acquisition/Quality Control, Pharmacy, Radiology, Dietary, Respiratory Therapy, ECG, EEG, Cardiology, Physical/Occupational Therapy and Nursing. These systems and numerous financial systems have been installed in a highly tuned, efficient computer system. All applications are real-time, on-line, and data base oriented. Each system is provided with multiple data security levels, forward file recovery, and dynamic transaction backout of in-flight tasks. Sensitive medical information is safeguarded by job function passwords, identification codes, need-to-know master screens and terminal keylocks. University Hospital has an IBM 3083 CPU with five 3380 disk drives, four dual density tape drives, and a 3705 network controller. The network of 300 terminals and 100 printers is connected to the computer center by an RF broadband cable. The software is configured around the IBM/MVS operating system using CICS as the telecommunication monitor, IMS as the data base management system and PCS/ADS as the application enabling tool. The most extensive clinical system added to UHIS is the Physiological Monitoring/Patient Data Management System with serves 92 critical care beds. In keeping with the Hospital's philosophy of integrated computing, the PMS/PDMS with its network of minicomputers was linked to the UHIS system. In a pilot program, remote access to UHIS through the IBM personal computer has been implemented in several physician offices in the local community, further extending the communications

  17. Doubly infinite separation of quantum information and communication

    NASA Astrophysics Data System (ADS)

    Liu, Zi-Wen; Perry, Christopher; Zhu, Yechao; Koh, Dax Enshan; Aaronson, Scott

    2016-01-01

    We prove the existence of (one-way) communication tasks with a subconstant versus superconstant asymptotic gap, which we call "doubly infinite," between their quantum information and communication complexities. We do so by studying the exclusion game [C. Perry et al., Phys. Rev. Lett. 115, 030504 (2015), 10.1103/PhysRevLett.115.030504] for which there exist instances where the quantum information complexity tends to zero as the size of the input n increases. By showing that the quantum communication complexity of these games scales at least logarithmically in n , we obtain our result. We further show that the established lower bounds and gaps still hold even if we allow a small probability of error. However in this case, the n -qubit quantum message of the zero-error strategy can be compressed polynomially.

    Agrell, Erik; Alvarado, Alex; Kschischang, Frank R

    2016-03-06

    Recent decades have witnessed steady improvements in our ability to harness the information-carrying capability of optical fibres. Will this process continue, or will progress eventually stall? Information theory predicts that all channels have a limited capacity depending on the available transmission resources, and thus it is inevitable that the pace of improvements will slow. However, information theory also provides insights into how transmission resources should, in principle, best be exploited, and thus may serve as a guide for where to look for better ways to squeeze more out of a precious resource. This tutorial paper reviews the basic concepts of information theory and their application in fibre-optic communications.

  20. Advanced Communications Technology Satellite (ACTS) Used for Inclined Orbit Operations

    NASA Technical Reports Server (NTRS)

    Bauer, Robert A.

    2000-01-01

    The Advanced Communications Technology Satellite (ACTS) is operated by the NASA Glenn Research Center at Lewis Field 24 hours a day, 7 days a week. ACTS, which was launched in September 1993, is in its 7th year of operations, far exceeding the system s planned 2 years of operations and 4 years of designed mission life. After 5 successful years of operating as a geostationary satellite, the spacecraft s North-South stationkeeping was discontinued in August 1998. The system is now operating in an inclined orbit that increases at a rate of 0.8 /yr. With only scarce fuel remaining, operating in this mode extends the usage of the still totally functional payload. Although tracking systems are now needed on the experimenter Earth stations, experiment operations have continued with very little disruption. This is the only known geosynchronous Ka-band (30/20 GHz) spot-beam satellite operating in an inclined orbit. The project began its transition from geostationary operations to inclined operations in August 1998. This did not interrupt operations and was transparent to the experimenters on the system. For the space segment, new daily procedures were implemented to maintain the pointing of the system s narrow 0.3 spot beams while the spacecraft drifts in the North-South direction. For the ground segment, modifications were designed, developed, and fielded for the three classes of experimenter Earth stations. With the next generation of commercial satellite systems still being developed, ACTS remains the only operational testbed for Ka-band geosynchronous satellite communications over the Western hemisphere. Since inclined orbit operations began, the ACTS experiments program has supported 43 investigations by industry, Government, and academic organizations, as well as four demonstrations. The project s goals for inclined-orbit operations now reflect a narrower focus in the types of experiments that will be done. In these days of "faster, better, cheaper," NASA is seeking

  1. Nonlocal Quantum Information Transfer Without Superluminal Signalling and Communication

    NASA Astrophysics Data System (ADS)

    Walleczek, Jan; Grössing, Gerhard

    2016-09-01

    It is a frequent assumption that—via superluminal information transfers—superluminal signals capable of enabling communication are necessarily exchanged in any quantum theory that posits hidden superluminal influences. However, does the presence of hidden superluminal influences automatically imply superluminal signalling and communication? The non-signalling theorem mediates the apparent conflict between quantum mechanics and the theory of special relativity. However, as a `no-go' theorem there exist two opposing interpretations of the non-signalling constraint: foundational and operational. Concerning Bell's theorem, we argue that Bell employed both interpretations, and that he finally adopted the operational position which is associated often with ontological quantum theory, e.g., de Broglie-Bohm theory. This position we refer to as "effective non-signalling". By contrast, associated with orthodox quantum mechanics is the foundational position referred to here as "axiomatic non-signalling". In search of a decisive communication-theoretic criterion for differentiating between "axiomatic" and "effective" non-signalling, we employ the operational framework offered by Shannon's mathematical theory of communication, whereby we distinguish between Shannon signals and non-Shannon signals. We find that an effective non-signalling theorem represents two sub-theorems: (1) Non-transfer-control (NTC) theorem, and (2) Non-signification-control (NSC) theorem. Employing NTC and NSC theorems, we report that effective, instead of axiomatic, non-signalling is entirely sufficient for prohibiting nonlocal communication. Effective non-signalling prevents the instantaneous, i.e., superluminal, transfer of message-encoded information through the controlled use—by a sender-receiver pair —of informationally-correlated detection events, e.g., in EPR-type experiments. An effective non-signalling theorem allows for nonlocal quantum information transfer yet—at the same time

  2. Social gating of sensory information during ongoing communication.

    2015-01-01

    Social context plays an important role in human communication. Depending on the nature of the source, the same communication signal might be processed in fundamentally different ways. However, the selective modulation (or "gating") of the flow of neural information during communication is not fully understood. Here, we use multivoxel pattern analysis (MVPA) and multivoxel connectivity analysis (MVCA), a novel technique that allows to analyse context-dependent changes of the strength interregional coupling between ensembles of voxels, to examine how the human brain differentially gates content-specific sensory information during ongoing perception of communication signals. In a simulated electronic communication experiment, participants received two alternative text messages during fMRI ("happy" or "sad") which they believed had been sent either by their real-life friend outside the scanner or by a computer. A region in the dorsal medial prefrontal cortex (dmPFC) selectively increased its functional coupling with sensory-content encoding regions in the visual cortex when a text message was perceived as being sent by the participant's friend, and decreased its functional coupling with these regions when a text message was perceived as being sent by the computer. Furthermore, the strength of neural encoding of content-specific information of text messages in the dmPFC was modulated by the social tie between the participant and her friend: the more of her spare time a participant reported to spend with her friend the stronger was the neural encoding. This suggests that the human brain selectively gates sensory information into the relevant network for processing the mental states of others, depending on the source of the communication signal.

  5. Information and communication technology needs for distributed communication and coordination during expedition-class spaceflight.

    PubMed

    Caldwell, B S

    2000-09-01

    AO-lU. Expedition-class missions are distinct from historical human presence in space in ways that significantly affect information flow and information technology designs for such missions. The centrality of Mission Control in these missions is challenged by the distances, associated communication delays, and durations of expeditions, all of which require crews to have more local resources available to manage on-board situations. The author's current research investigates how ground controllers effectively allocate communications bandwidth, cognitive resources, and knowledge sharing skills during time critical routine and non-routine situations. The research focus is on team-based information and communication technology (ICT) use to provide recommendations for improvements to support adaptive bandwidth allocations and improved sharing of data and knowledge in Mission Control contexts. In order to further improve communication and coordination between controllers and crew, additional ICT support resources will be needed to provide shared context knowledge and dynamic assessment of costs and benefits for accessing local information vs. remote expertise. Crew members will have critical needs to understand the goals, intentions, and situational constraints associated with mission information resources in order to use them most effectively in conditions where ground-based expertise is insufficient or requires more time to access and coordinate than local task demands permit. Results of this research will serve to improve the design and implementation of ICT systems to improve human performance capabilities and system operating tolerances for exploration missions.

    2017-03-01

    Recent research has demonstrated enhanced communicative abilities in bilingual children compared with monolingual children throughout childhood and in a variety of domains. The processes underlying these advantages are, however, not well understood. It has been suggested that one aspect that particularly stimulates bilinguals' communication skills is their daily experience with challenging communication. In the current study, we investigated whether children's assumed experience with communication failures would increase their skills when it came to repairing communication failure. Non-German bilingual, German bilingual, and monolingual 2.5-year-old toddlers participated in a communication task in which a misunderstanding occurred. We hypothesized that monolingual and German bilingual children would have fewer daily communication failures-and, therefore, less well-trained repair skills-compared with non-German bilinguals. The results showed that non-German bilinguals were more likely to repair the misunderstanding compared with both monolingual children and German bilingual children. The current findings support the view that the communicative advantages of bilingual individuals develop based on their unique experience with interpersonal communication and its difficulties.

    2016-09-01

    Healthcare facilities use a number of information system/information and communication technologies. Each healthcare facility faces a need to choose sourcing strategies most suitable to ensure provision of information system/information and communication technology services, processes and resources. Currently, it is possible to observe an expansion of sourcing possibilities in healthcare informatics, which creates new requirements for sourcing strategies. Thus, the aim of this article is to identify factors influencing information system/information and communication technology sourcing strategies in healthcare facilities. The identification was based on qualitative research, namely, a case study. This study provides a set of internal and external factors with their impact levels. The findings also show that not enough attention is paid to these factors during decision-making.

    Communication has always had a very important role among human activities. Communication is: a Source sending a Message to an Addressee within a Context through a Contact thanks to a Code. In 1965 Umberto Eco developed the concept of Aberrant Decoding that is the wrong decoding of the message by the addressee. As to communication D.Lgs81/08 e s.m.i. fixes the following rules. Information of workers (Art. 36/1)--The employer is responsible for the workers to have the right information about risks for health and safety in their specific workplaces, etc. Formation of workers (Art 37/1)--The employer is responsible for the workers to have adequate and proper formation as to health and safety with regard to linguistic knowledge. Therefore it is really important for a Company to establish real communication between management and workers and among workers, to have a frequent feedback and to let information circulate in order to have all safety regulations followed properly.

    In this presentation we review the current ongoing research within George Mason University's (GMU) Center for Information Systems Integration and Evolution (CISE). We define characteristics of advanced information systems, discuss a family of agents for such systems, and show how GMU's Domain modeling tools and techniques can be used to define a product line Architecture for configuring NASA missions. These concepts can be used to define Advanced Engineering Environments such as those envisioned for NASA's new initiative for intelligent design and synthesis environments.

  15. Privacy and intra-familiy communication of genetic information.

    2004-01-01

    The new knowledge (and predictions) created by DNA tests and the family nature of genetic information has already lead to a new problem: the intra-familiar communication of genetic data. This raises questions such as the following. Is there a duty to inform in cases when treatment is possible and the patient does not permit disclosure of genetic results to relatives? Is there an obligation to warn or merely an authorization (that could be used or not)? Could privacy protection be maintain as an individual interest but with some justified violations? A balance needs to be establishes between the interest of privacy and the need to disclose secret information.

    Nowadays, acquiring, managing, disseminating and understanding information through new technologies is an important aspect of our daily life. We can search for and store information, but we can also spread it. The proper handling of information and communications technology (TICs) is beneficial, but does not reach all alike. The difficulties posed by the elderly when adapting to TICs are increased by the fact that they are unknown and unfamiliar to them, resulting in rejection from the elderly and thus an increased risk of inequality and social exclusion. TICs value in aging lies in the improvement of self-learning and personal development as well as in promoting participation, social integration and healthy aging.

    This report covers work performed in Phase II of a two phase project whose objective was to demonstrate the aggregation of multiple Distributed Energy Resources (DERs) and to offer them into the energy market. The Phase I work (DE-FC36-03CH11161) created an integrated, but distributed, system and procedures to monitor and control multiple DERs from numerous manufacturers connected to the electric distribution system. Procedures were created which protect the distribution network and personnel that may be working on the network. Using the web as the communication medium for control and monitoring of the DERs, the integration of information and security was accomplished through the use of industry standard protocols such as secure SSL,VPN and ICCP. The primary objective of Phase II was to develop the procedures for marketing the power of the Phase I aggregated DERs in the energy market, increase the number of DER units, and implement the marketing procedures (interface with ISOs) for the DER generated power. The team partnered with the Midwest Independent System Operator (MISO), the local ISO, to address the energy market and demonstrate the economic dispatch of DERs in response to market signals. The selection of standards-based communication technologies offers the ability of the system to be deployed and integrated with other utilities’ resources. With the use of a data historian technology to facilitate the aggregation, the developed algorithms and procedures can be verified, audited, and modified. The team has demonstrated monitoring and control of multiple DERs as outlined in phase I report including procedures to perform these operations in a secure and safe manner. In Phase II, additional DER units were added. We also expanded on our phase I work to enhance communication security and to develop the market model of having DERs, both customer and utility owned, participate in the energy market. We are proposing a two-part DER energy market model--a utility

    The Glenn Research Center (GRC) Direct Data Distribution (D3) project will demonstrate an advanced, high-performance communication system that transmits information from a technology payload carried by the Space Shuttle in low-Earth orbit (LEO) to a small receiving terminal on the Earth. The Shuttle-based communications package will utilize a solid-state, Ka-band phased array antenna that electronically steers the 19.05 Ghz RF signal toward a low-cost, tracking ground terminal, thereby providing agile, vibration-free, electronic steering at reduced size and weight with increased reliability. The project will also demonstrate new digital modulation and processing technology that will allow transmission of user/platform data at rates up to 1200 Mbits per second. This capability will enable the management of the substantially increased amounts of data to be collected from the International Space Station (ISS) or other LEO platforms directly to NASA field centers, principal investigators, or into the commercial terrestrial communications network. .

  2. Minimal classical communication and measurement complexity for quantum information splitting

    NASA Astrophysics Data System (ADS)

    Zhang, Zhan-jun; Cheung, Chi-Yee

    2008-01-01

    We present two quantum information splitting schemes using respectively tripartite GHZ and asymmetric W states as quantum channels. We show that if the secret state is chosen from a special ensemble and known to the sender (Alice), then she can split and distribute it to the receivers Bob and Charlie by performing only a single-qubit measurement and broadcasting a one-cbit message. It is clear that no other schemes could possibly achieve the same goal with simpler measurement and less classical communication. In comparison, existing schemes work for arbitrary quantum states which need not be known to Alice; however she is required to perform a two-qubit Bell measurement and communicate a two-cbit message. Hence there is a trade-off between flexibility and measurement complexity plus classical resource. In situations where our schemes are applicable, they will greatly reduce the measurement complexity and at the same time cut the communication overhead by one half.

    Issues related to the reliability of a redundant system with large main memory are addressed. In particular, the Fault-Tolerant Processor (FTP) for Advanced Launch System (ALS) is used as a basis for our presentation. When the system is free of latent faults, the probability of system crash due to nearly-coincident channel faults is shown to be insignificant even when the outputs of computing channels are infrequently voted on. In particular, using channel error maskers (CEMs) is shown to improve reliability more effectively than increasing the number of channels for applications with long mission times. Even without using a voter, most memory errors can be immediately corrected by CEMs implemented with conventional coding techniques. In addition to their ability to enhance system reliability, CEMs--with a low hardware overhead--can be used to reduce not only the need of memory realignment, but also the time required to realign channel memories in case, albeit rare, such a need arises. Using CEMs, we have developed two schemes, called Scheme 1 and Scheme 2, to solve the memory realignment problem. In both schemes, most errors are corrected by CEMs, and the remaining errors are masked by a voter.

    Drug adherence is central to the treatment of dementia, which might reduce compliance due to memory loss, particularly among home-based patients with dementia. In order to improve drug adherence, we suggest the efficient and effective supervised administration by use of information communication technology(ICT). ICT makes face-to-face real-time communication possible, and it also enables picture sharing. Therefore, it might be useful to apply ICT to controlling and supervising medication for patients with dementia to improve drug adherence. Accordingly, we enrolled patients who were supposed to take a newly prescribed anti-dementia patch containing the choline esterase inhibitor rivastigmine(Rivastach®)and investigated the effect of ICT-based intervention for drug adherence, emotional change, and cognitive change, utilizing Skype, a free communication software program. Scheduled Skype interventions increased drug adherence ratio, levels of subjective satisfaction, and instrumental activities of daily living(IADL). Furthermore, we can provide patients and their caregivers with a feeling of safety through regular bidirectional communication, as patients can easily consult medical staff regarding the adverse effects of newly prescribed drugs. Instead of frequent visits to their primary physicians, ICT-based communications can be used as a substitute for supervision of medication, given the availability of the telecommunication system. By directly connecting the medical institution to the home, we expect that this ICT-based system will expand into the geriatric care field, including the care of elderly individuals living alone.

    The purpose of the NASA Glenn Research Center Weather Information Communications (WINCOMM) project was to develop advanced communications and information technologies to enable the high-quality and timely dissemination of strategic weather information between the flight deck and ground users as well as tactical turbulence hazard information between relevant aircraft and to the ground. This report will document and reference accomplishments on the dissemination of weather information during the en route phase of flight from ground-based weather information providers to the flight deck (ground-to-air), from airborne meteorological sensors to ground users (air-to-ground), and weather turbulence and icing hazard information between relevant aircraft (air-to-air). In addition, references in this report will demonstrate the architecture necessary to implement and perform successful transmission and reception of weather information to the cockpit, show that weather information flow does not impact "normal" traffic, demonstrate the feasibility of operational implementation, and lay foundation for future data link development.

    2015-01-01

    Background Family communication is central to the family and its functioning. It is a mutual process in which family members create, share, and regulate meaning. Advancement and proliferation of information and communication technologies (ICTs) continues to change methods of family communication. However, little is known about the use of different methods for family communication and the influence on family well-being. Objective We investigated the sociodemographic factors associated with different methods of family communication and how they are associated with perceived family harmony, happiness, and health (3Hs) among Chinese adults in Hong Kong. Methods Data came from a territory-wide probability-based telephone survey using the Family and Health Information Trend survey (FHInTs). Frequency of family communication using different methods (ie, face-to-face, phone, instant messaging [IM], social media sites, and email) were recoded and classified as frequent (always/sometimes) and nonfrequent (seldom/never) use. Family well-being was measured using 3 questions of perceived family harmony, happiness, and health with higher scores indicating better family well-being. Adjusted odds ratios for family communication methods by sociodemographic characteristics and adjusted beta coefficients for family well-being by communication methods were calculated. Results A total of 1502 adults were surveyed. Face-to-face (94.85%, 1408/1484) was the most frequent means of communication followed by phone (78.08%, 796/1484), IM (53.64%, 796/1484), social media sites (17.60%, 261/1484), and email (13.39%, 198/1484). Younger age was associated with the use of phone, IM, and social media sites for family communication. Higher educational attainment was associated with more frequent use of all modes of communication, whereas higher family income was only significantly associated with more frequent use of IM and email (P=.001). Face-to-face (beta 0.65, 95% CI 0.33-0.97) and phone use

    2016-01-01

    Background Consumer health information technology (IT) solutions are designed to support patient health management and have the ability to facilitate patients’ health information communication with their social networks. However, there is a need for consumer health IT solutions to align with patients’ health management preferences for increased adoption of the technology. It may be possible to gain an understanding of patients’ needs for consumer health IT supporting their health information communication with social networks by explicating how they have adopted and adapted social networking sites, such as Facebook, for this purpose. Objective Our aim was to characterize patients’ use of all communication mechanisms within Facebook for health information communication to provide insight into how consumer health IT solutions may be better designed to meet patients’ communication needs and preferences. Methods This study analyzed data about Facebook communication mechanisms use from a larger, three-phase, sequential, mixed-methods study. We report here on the results of the study’s first phase: qualitative interviews (N=25). Participants were over 18, used Facebook, were residents or citizens of the United States, spoke English, and had a diagnosis consistent with type 2 diabetes. Participants were recruited through Facebook groups and pages. Participant interviews were conducted via Skype or telephone between July and September 2014. Data analysis was grounded in qualitative content analysis and the initial coding framework was informed by the findings of a previous study. Results Participants’ rationales for the use or disuse of a particular Facebook mechanism to communicate health information reflected six broad themes: (1) characteristics and circumstances of the person, (2) characteristics and circumstances of the relationship, (3) structure and composition of the social network, (4) content of the information, (5) communication purpose, and (6

  2. Microscopic information processing and communication in crowd dynamics

    NASA Astrophysics Data System (ADS)

    Henein, Colin Marc; White, Tony

    2010-11-01

    Due, perhaps, to the historical division of crowd dynamics research into psychological and engineering approaches, microscopic crowd models have tended toward modelling simple interchangeable particles with an emphasis on the simulation of physical factors. Despite the fact that people have complex (non-panic) behaviours in crowd disasters, important human factors in crowd dynamics such as information discovery and processing, changing goals and communication have not yet been well integrated at the microscopic level. We use our Microscopic Human Factors methodology to fuse a microscopic simulation of these human factors with a popular microscopic crowd model. By tightly integrating human factors with the existing model we can study the effects on the physical domain (movement, force and crowd safety) when human behaviour (information processing and communication) is introduced. In a large-room egress scenario with ample exits, information discovery and processing yields a crowd of non-interchangeable individuals who, despite close proximity, have different goals due to their different beliefs. This crowd heterogeneity leads to complex inter-particle interactions such as jamming transitions in open space; at high crowd energies, we found a freezing by heating effect (reminiscent of the disaster at Central Lenin Stadium in 1982) in which a barrier formation of naïve individuals trying to reach blocked exits prevented knowledgeable ones from exiting. Communication, when introduced, reduced this barrier formation, increasing both exit rates and crowd safety.

  2. Advanced communications technology satellite high burst rate link evaluation terminal communication protocol software user's guide, version 1.0

    NASA Technical Reports Server (NTRS)

    Reinhart, Richard C.

    1993-01-01

    The Communication Protocol Software was developed at the NASA Lewis Research Center to support the Advanced Communications Technology Satellite High Burst Rate Link Evaluation Terminal (ACTS HBR-LET). The HBR-LET is an experimenters terminal to communicate with the ACTS for various experiments by government, university, and industry agencies. The Communication Protocol Software is one segment of the Control and Performance Monitor (C&PM) Software system of the HBR-LET. The Communication Protocol Software allows users to control and configure the Intermediate Frequency Switch Matrix (IFSM) on board the ACTS to yield a desired path through the spacecraft payload. Besides IFSM control, the C&PM Software System is also responsible for instrument control during HBR-LET experiments, uplink power control of the HBR-LET to demonstrate power augmentation during signal fade events, and data display. The Communication Protocol Software User's Guide, Version 1.0 (NASA CR-189162) outlines the commands and procedures to install and operate the Communication Protocol Software. Configuration files used to control the IFSM, operator commands, and error recovery procedures are discussed. The Communication Protocol Software Maintenance Manual, Version 1.0 (NASA CR-189163, to be published) is a programmer's guide to the Communication Protocol Software. This manual details the current implementation of the software from a technical perspective. Included is an overview of the Communication Protocol Software, computer algorithms, format representations, and computer hardware configuration. The Communication Protocol Software Test Plan (NASA CR-189164, to be published) provides a step-by-step procedure to verify the operation of the software. Included in the Test Plan is command transmission, telemetry reception, error detection, and error recovery procedures.

  3. The use of information and communication technology (ICT) in dentistry.

    PubMed

    Knott, N J

    2013-02-01

    As the use of information and communication technology (ICT) becomes more widespread in dentistry the risk of breaching electronic commerce laws and patient confidentiality increases. It is necessary to be aware of the responsibilities internet usage entails, especially within a dental practice where the protection of patient information is of the utmost importance. More should be done to outline the various precautions that should be taken to ensure ICT security within the professional domain, as it would appear dentistry has been neglected with regard to receiving the proper ICT education, training and support systems.

    Marker, W.; Whitelaw, V.; Muratore, J.; Bigham, J., Jr.

    1987-01-01

    Space Station Information System (SSIS) requirements for integrated end-to-end communications are presented. The SSIS is defined as the integrated set of space and ground data and information systems and networks which will provide required data services to the Space Station flight crew, ground operations personnel, and customer communities. This model is based on the International Standards Organization (ISO) layered model for Open System Interconnection (OSI). These SSIS requirements include grades of service, priority classifications, systems management, flow control, bandwidth allocation, and standard SSIS data services.

  8. Evolution of natural agents: preservation, advance, and emergence of functional information.

    PubMed

    Sharov, Alexei A

    2016-04-01

    Biological evolution is often viewed narrowly as a change of morphology or allele frequency in a sequence of generations. Here I pursue an alternative informational concept of evolution, as preservation, advance, and emergence of functional information in natural agents. Functional information is a network of signs (e.g., memory, transient messengers, and external signs) that are used by agents to preserve and regulate their functions. Functional information is preserved in evolution via complex interplay of copying and construction processes: the digital components are copied, whereas interpreting subagents together with scaffolds, tools, and resources, are constructed. Some of these processes are simple and invariant, whereas others are complex and contextual. Advance of functional information includes improvement and modification of already existing functions. Although the genome information may change passively and randomly, the interpretation is active and guided by the logic of agent behavior and embryonic development. Emergence of new functions is based on the reinterpretation of already existing information, when old tools, resources, and control algorithms are adopted for novel functions. Evolution of functional information progressed from protosemiosis, where signs correspond directly to actions, to eusemiosis, where agents associate signs with objects. Language is the most advanced form of eusemiosis, where the knowledge of objects and models is communicated between agents.

  11. Evaluating true BCI communication rate through mutual information and language models.

    PubMed

    Speier, William; Arnold, Corey; Pouratian, Nader

    2013-01-01

    Brain-computer interface (BCI) systems are a promising means for restoring communication to patients suffering from "locked-in" syndrome. Research to improve system performance primarily focuses on means to overcome the low signal to noise ratio of electroencephalogric (EEG) recordings. However, the literature and methods are difficult to compare due to the array of evaluation metrics and assumptions underlying them, including that: 1) all characters are equally probable, 2) character selection is memoryless, and 3) errors occur completely at random. The standardization of evaluation metrics that more accurately reflect the amount of information contained in BCI language output is critical to make progress. We present a mutual information-based metric that incorporates prior information and a model of systematic errors. The parameters of a system used in one study were re-optimized, showing that the metric used in optimization significantly affects the parameter values chosen and the resulting system performance. The results of 11 BCI communication studies were then evaluated using different metrics, including those previously used in BCI literature and the newly advocated metric. Six studies' results varied based on the metric used for evaluation and the proposed metric produced results that differed from those originally published in two of the studies. Standardizing metrics to accurately reflect the rate of information transmission is critical to properly evaluate and compare BCI communication systems and advance the field in an unbiased manner.

  12. The Effect of Health Information Technology on Health Care Provider Communication: A Mixed-Method Protocol

    2015-01-01

    Background Communication failures between physicians and nurses are one of the most common causes of adverse events for hospitalized patients, as well as a major root cause of all sentinel events. Communication technology (ie, the electronic medical record, computerized provider order entry, email, and pagers), which is a component of health information technology (HIT), may help reduce some communication failures but increase others because of an inadequate understanding of how communication technology is used. Increasing use of health information and communication technologies is likely to affect communication between nurses and physicians. Objective The purpose of this study is to describe, in detail, how health information and communication technologies facilitate or hinder communication between nurses and physicians with the ultimate goal of identifying how we can optimize the use of these technologies to support effective communication. Effective communication is the process of developing shared understanding between communicators by establishing, testing, and maintaining relationships. Our theoretical model, based in communication and sociology theories, describes how health information and communication technologies affect communication through communication practices (ie, use of rich media; the location and availability of computers) and work relationships (ie, hierarchies and team stability). Therefore we seek to (1) identify the range of health information and communication technologies used in a national sample of medical-surgical acute care units, (2) describe communication practices and work relationships that may be influenced by health information and communication technologies in these same settings, and (3) explore how differences in health information and communication technologies, communication practices, and work relationships between physicians and nurses influence communication. Methods This 4-year study uses a sequential mixed

  14. Directedness of information flow in mobile phone communication networks.

    PubMed

    Peruani, Fernando; Tabourier, Lionel

    2011-01-01

    Without having direct access to the information that is being exchanged, traces of information flow can be obtained by looking at temporal sequences of user interactions. These sequences can be represented as causality trees whose statistics result from a complex interplay between the topology of the underlying (social) network and the time correlations among the communications. Here, we study causality trees in mobile-phone data, which can be represented as a dynamical directed network. This representation of the data reveals the existence of super-spreaders and super-receivers. We show that the tree statistics, respectively the information spreading process, are extremely sensitive to the in-out degree correlation exhibited by the users. We also learn that a given information, e.g., a rumor, would require users to retransmit it for more than 30 hours in order to cover a macroscopic fraction of the system. Our analysis indicates that topological node-node correlations of the underlying social network, while allowing the existence of information loops, they also promote information spreading. Temporal correlations, and therefore causality effects, are only visible as local phenomena and during short time scales. Consequently, the very idea that there is (intentional) information spreading beyond a small vecinity is called into question. These results are obtained through a combination of theory and data analysis techniques.

  10. LTE-advanced random access mechanism for M2M communication: A review

    NASA Astrophysics Data System (ADS)

    Mustafa, Rashid; Sarowa, Sandeep; Jaglan, Reena Rathee; Khan, Mohammad Junaid; Agrawal, Sunil

    2016-03-01

    Machine Type Communications (MTC) enables one or more self-sufficient machines to communicate directly with one another without human interference. MTC applications include smart grid, security, e-Health and intelligent automation system. To support huge numbers of MTC devices, one of the challenging issues is to provide a competent way for numerous access in the network and to minimize network overload. In this article, the different control mechanisms for overload random access are reviewed to avoid congestion caused by random access channel (RACH) of MTC devices. However, past and present wireless technologies have been engineered for Human-to-Human (H2H) communications, in particular, for transmission of voice. Consequently the Long Term Evolution (LTE) -Advanced is expected to play a central role in communicating Machine to Machine (M2M) and are very optimistic about H2H communications. Distinct and unique characteristics of M2M communications create new challenges from those in H2H communications. In this article, we investigate the impact of massive M2M terminals attempting random access to LTE-Advanced all at once. We discuss and review the solutions to alleviate the overload problem by Third Generation Partnership Project (3GPP). As a result, we evaluate and compare these solutions that can effectively eliminate the congestion on the random access channel for M2M communications without affecting H2H communications.

  11. Information trade-offs for optical quantum communication.

    PubMed

    Wilde, Mark M; Hayden, Patrick; Guha, Saikat

    2012-04-06

    Recent work has precisely characterized the achievable trade-offs between three key information processing tasks-classical communication (generation or consumption), quantum communication (generation or consumption), and shared entanglement (distribution or consumption), measured in bits, qubits, and ebits per channel use, respectively. Slices and corner points of this three-dimensional region reduce to well-known protocols for quantum channels. A trade-off coding technique can attain any point in the region and can outperform time sharing between the best-known protocols for accomplishing each information processing task by itself. Previously, the benefits of trade-off coding that had been found were too small to be of practical value (viz., for the dephasing and the universal cloning machine channels). In this Letter, we demonstrate that the associated performance gains are in fact remarkably high for several physically relevant bosonic channels that model free-space or fiber-optic links, thermal-noise channels, and amplifiers. We show that significant performance gains from trade-off coding also apply when trading photon-number resources between transmitting public and private classical information simultaneously over secret-key-assisted bosonic channels.

Previously, the benefits of trade-off coding that had been found were too small to be of practical value (viz., for the dephasing and the universal cloning machine channels). In this Letter, we demonstrate that the associated performance gains are in fact remarkably high for several physically relevant bosonic channels that model free-space or fiber-optic links, thermal-noise channels, and amplifiers. We show that significant performance gains from trade-off coding also apply when trading photon-number resources between transmitting public and private classical information simultaneously over secret-key-assisted bosonic channels.

    In recent years, progress in information and communication technology (ICT) has caused many structural changes such as reorganizing of economics, globalization, and trade extension, which leads to capital flows and enhancing information availability. Moreover, ICT plays a significant role in development of each economic sector, especially during liberalization process. Growth economists predict that economic growth is driven by investments in ICT. However, empirical studies on this issue have produced mixed results, regarding to different research methodology and geographical configuration of the study. This paper examines the impact of Information and Communication Technology (ICT) use on economic growth using the Generalized Method of Moments (GMM) estimator within the framework of a dynamic panel data approach and applies it to 159 countries over the period 2000 to 2009. The results indicate that there is a positive relationship between growth rate of real GDP per capita and ICT use index (as measured by the number of internet users, fixed broadband internet subscribers and the number of mobile subscription per 100 inhabitants). We also find that the effect of ICT use on economic growth is higher in high income group rather than other groups. This implies that if these countries seek to enhance their economic growth, they need to implement specific policies that facilitate ICT use.

    Developed countries like USA, Canada, Japan, UK, Australia and Germany have adopted advanced traveler information technologies expeditiously in comparison to developing countries. But, unlike developed countries, developing countries face considerable financial and framework constraints. Moreover local traffic, roadway, signalization, demographic, topological and social conditions in developing countries are quite different from those in developed countries. In this paper, a comprehensive framework comprising of system architecture, development methodology and salient features of a developed Advanced Traveler Information System (ATIS) for metropolitan cities in developing countries has been discussed. Development of proposed system is based on integration of two well known information technologies viz. Geographic Information Systems (GIS) and World Wide Web (WWW). Combination of these technologies can be utilized to develop an integrated ATIS that targets different types of travelers like private vehicle owners, transit users and casual outside visitors.

    The internet provides new opportunities to deliver distance and e-learning to the veterinary profession both at undergraduate and postgraduate levels. There are now numerous examples of successful computer-based educational projects in UK higher education, which provide useful models for veterinary science. This will present challenges for academics who will need to adapt their teaching methodologies and students who will have to develop new ways of learning. The future of Information and Communication Technologies (ICT) in the veterinary sector is difficult to predict but it is likely to have far reaching effects on the profession.

    This article provides a general framework for understanding the use of information and communication technology in education and discusses the impact of computer usage on students' health and development. Potential beneficial and harmful effects of computer use by children are discussed. Early epidemiological and laboratory studies have indicated that children are at least of similar risk of developing musculoskeletal and vision problems as adults, and musculoskeletal and visual health problems developed in childhood are likely to persist into adulthood. This article, therefore, aims to provide a reflection on the deficits of existing policy and recommendations for child-specific guidelines in computer use.

    Around the world, inventors are creating novel information and communication technology applications and systems that can improve health for people in disparate settings. However, it is very difficult to find investment funding needed to create business models to expand and develop the prototype technologies. A comprehensive, long-term investment strategy for e-health and m-health is needed. The field of social entrepreneurship offers an integrated approach to develop needed investment models, so that innovations can reach more patients, more effectively. Specialized financing techniques and sustained support from investors can spur the expansion of mature technologies to larger markets, accelerating global health impacts.

    2000-01-01

    approximately five satellites on the orbital arc. Spread spectrum techniques will be employed to keep the power impinging on the adjacent satellites below their noise floor so that no interference results. This antenna is power limited. If the antenna elements (currently 254) are increased by a factor of 4 (1024) or 16 (4096), the gain will increase and the beamwidth will decrease in proportion. For the latter two antenna sizes, the power must be "backed off" to prevent interference with the neighboring satellites. The receiving antenna, which is approximately 90-cm high, 60-cm wide, and 3.5-cm thick, is composed of 1500 phased-array elements. The system phased-array controller can control both a 1500-element receiving antenna and a 500-element transmitting antenna. For ground testing, this controller will allow manual beam pointing and polarization alignment. For normal operation, the system can be connected to the receiving antenna and the navigation system for real-time autonomous track operation. This will be accomplished by first pointing both antennas at the satellite using information from the aircraft data bus. Then, the system phased-array controller will electronically adjust the antenna pointing of the receiving antenna to find the peak signal. After the peak signal has been found, the beam of the transmitting antenna will be pointed to the same steering angles as the receiving antenna. For initial ground testing without an aircraft, the ARINC 429 data bus (ARINC Inc., Annapolis, Maryland) will be simulated by a gyro system purchased for the follow-on to the Monolithic Microwave Integrated Circuit (MMIC) Arrays for Satellite Communication on the Move (MASCOM) Project. MASCOM utilized the Advanced Communications Technology Satellite (ACTS) with a pair of Ka-band experimental phased-array antennas.

    1982-01-01

    The efficiency of various deep space communication systems which are required to transmit both imaging and a typically error sensitive class of data called general science and engineering (gse) are compared. The approach jointly treats the imaging and gse transmission problems, allowing comparisons of systems which include various channel coding and data compression alternatives. Actual system comparisons include an advanced imaging communication system (AICS) which exhibits the rather significant advantages of sophisticated data compression coupled with powerful yet practical channel coding. For example, under certain conditions the improved AICS efficiency could provide as much as two orders of magnitude increase in imaging information rate compared to a single channel uncoded, uncompressed system while maintaining the same gse data rate in both systems. Additional details describing AICS compression and coding concepts as well as efforts to apply them are provided in support of the system analysis.

    2008-05-01

    There has been much discussion of the role that recent advances in information and communication technologies (ICTs) could play in improving health systems in developing countries, but limited independent analysis of existing applications. Combining a case study approach with a general discussion of the issues, this paper attempts to assess the potential benefits of a diverse range of ICT innovations and some of the constraints they will need to overcome. Four broad areas are considered: improvements in traditional health information systems; computer-aided diagnosis and treatment monitoring; a range of applications generically labelled 'telemedicine'; and the use of ICT to inform general populations on health and healthcare. The final section speculates on the possible medium-term impacts of ICT in terms of improving the performance of existing systems, allowing scope for radical innovations, or even changing basic assumptions about the provider-patient relationship.

    In the mid 1980s the US Department of Energy (DOE) recognized the need to dramatically expand its Emergency Operations Centers to deal with the large variety of emergencies for which DOE has an obligation to manage, or provide technical support. This paper describes information management, display, and communications systems that have been implemented at the DOE Headquarters Forestall Operations Center (OC), DOE Operations Offices, and critical laboratory locations. Major elements of the system at the DOE Headquarters facility include computer control, information storage and retrieval, processing, Local Area Networks (LANs), videoconferencing, video display, and audio systems. These Headquarters systems are linked by Wide Area Networks (WANs) to similar systems at the Operations Office and critical Laboratory locations.

  9. Advancing Unmanned Aircraft Sensor Collection and Communication Capabilities with Optical Communications

    2015-12-01

    Unmanned aircraft systems (UAS) are now being used for monitoring climate change over both land and seas. Their uses include monitoring of cloud conditions and atmospheric composition of chemicals and aerosols due to pollution, dust storms, fires, volcanic activity and air-sea fluxes. Additional studies of carbon flux are important for various ecosystem studies of both marine and terrestrial environments specifically, and can be related to climate change dynamics. Many measurements are becoming more complex as additional sensors become small enough to operate on more widely available small UAS. These include interferometric radars as well as scanning and fan-beam lidar systems which produce data streams even greater than those of high resolution video. These can be used to precisely map surfaces of the earth, ocean or ice features that are important for a variety of earth system studies. As these additional sensor capabilities are added to UAS the ability to transmit data back to ground or ship monitoring sites is limited by traditional wireless communication protocols. We describe results of tests of optical communication systems that provide significantly greater communication bandwidths for UAS, and discuss both the bandwidth and effective range of these systems, as well as their power and weight requirements both for systems on UAS, as well as those of ground-based receiver stations. We justify our additional use of Delay and Disruption Tolerant Networking (DTN) communication protocols with optical communication methods to ensure security and continuity of command and control operations. Finally, we discuss the implications for receiving, geo-referencing, archiving and displaying data streams from sensors communicated via optical communication to better enable real-time anomaly detection and adaptive sampling capabilities using multiple UAS or other unmanned or manned systems.

    Access to technology in practice helps physicians manage information, communicate, and research topics; however, those in training receive almost no formal preparation for integrating web-based technologies into practice. One reason for this is that many faculty-aside from junior faculty or those in recent generations-did not grow up using Internet communication, may use it minimally, if at all, in their own practices, and may know little about its forms and varieties. This report presents a case to illustrate how these disparities may play out in the supervisory situation and makes suggestions about helping supervisors integrate technology-awareness into their teaching.

    Information and Communication Technologies (ICT) have merged into the world of healthcare slowly but surely. However, the marriage between the use of technology and its full impact in the health sector has not been fully realised. The focus of this paper is to highlight the impact of ICT on revolutionising access to healthcare information and thus quality of health for populations of the developing world. This paper highlights on the importance of being able to access health information and how traditional media methods have been utilised to allow this within a developing country setting, highlighting the clear digital divide. The paper then addresses the impact of convergent communication technologies and mobile technologies in providing a means of addressing existing healthcare problems within a developing country setting.

    The "siloed" approach to healthcare delivery contributes to communication challenges and to potential patient harm when patients transfer between settings. This article reports on the evaluation of a demonstration in 10 rural communities to improve the safety of nursing facility (NF) transfers to hospital emergency departments by forming interprofessional teams of hospital, emergency medical service, and NF staff to develop and implement tools and protocols for standardizing critical interfacility communication pathways and information sharing. We worked with each of the 10 teams to document current communication processes and information sharing tools and to design, implement, and evaluate strategies/tools to increase effective communication and sharing of patient information across settings. A mixed methods approach was used to evaluate changes from baseline in documentation of patient information shared across settings during the transfer process. Study findings showed significant improvement in key areas across the three settings, including infection status and baseline mental functioning. Improvement strategies and performance varied across settings; however, accurate and consistent information sharing of advance directives and medication lists remains a challenge. Study results demonstrate that with neutral facilitation and technical support, collaborative interfacility teams can assess and effectively address communication and information sharing problems that threaten patient safety.

    This study tested the usability of a touch-screen-enabled Personal Education Program with advanced practice RNs. The Personal Education Program is designed to enhance medication adherence and reduce adverse self-medication behaviors in older adults with hypertension. An iterative research process was used, which involved the use of (1) pretrial focus groups to guide the design of system information architecture, (2) two different cycles of think-aloud trials to test the software interface, and (3) post-trial focus groups to gather feedback on the think-aloud studies. Results from this iterative usability-testing process were used to systematically modify and improve the three Personal Education Program prototype versions-the pilot, prototype 1, and prototype 2. Findings contrasting the two separate think-aloud trials showed that APRN users rated the Personal Education Program system usability, system information, and system-use satisfaction at a moderately high level between trials. In addition, errors using the interface were reduced by 76%, and the interface time was reduced by 18.5% between the two trials. The usability-testing processes used in this study ensured an interface design adapted to APRNs' needs and preferences to allow them to effectively use the computer-mediated health-communication technology in a clinical setting.

    Coherent terahertz signal transmission with multilevel modulation and demodulation is demonstrated using an optical sub-harmonic IQ mixer (SHIQM), which consists of optical components in advanced optical fiber communication technologies. An optical-frequency-comb-employed signal generator is capable of vector modulation as well as frequency tunability. Digital signal processing (DSP) adopted from the recently developed optical digital coherent communication can easily demodulate multi-level modulated terahertz signals by using electrical heterodyning for intermediate-frequency (IF) down conversion. This technique is applicable for mobile backhauling in the next-generation mobile communication technology directly connected to an optical fiber network as a high-speed wireless transmission link.

    PubMed

    Lymberis, A

    2005-01-01

    The interest for wearable health systems originates mainly from the need to extend health services out of the hospital and monitor patients over extensive periods of time. Smart Wearable Health Systems (SWHS) are integrated systems in contact with or near to the body able to sense, (and/or act), process and communicate biomedical and physical parameters. Significant advances in biomedical technology, materials engineering, micro/nanotechnologies and Information and Communication Technologies (ICT) lead to new possibilities for increasing miniaturisation, communication capabilities and system "intelligence". The new possibilities for wearable monitoring are mainly provided at the level of microsensors, wrist and other body worn devices, and smart biomedical clothing. Research and development in these areas has been strongly supported through public funding and private investments worldwide. In Europe the major R&D activities were promoted and supported by the European Commission, Information Society Technologies (IST) programme, mainly through health telematics (telemedicine, e-Health) and micro-nano technologies activities. The aim of these projects was the development and testing of innovative integrated user-friendly systems, environments and scenarios of use that could lead to market exploitation in a short to mid term future (3-5 years). This paper presents the rationale and the results of research on wearable health systems in Europe and comments on the current challenges and futures perspectives in the field.

    Poor patient–provider communication in hospital continues to be cited as a possible causal factor in preventable adverse events for patients with severe communication disabilities. Yet to date there are no reports of empirical interventions that investigate or demonstrate an improvement in communication in hospital for these patients. The aim of this review was to synthesize the findings of research into communication in hospital for people with severe communication disabilities arising from lifelong and acquired stable conditions including cerebral palsy, autism, intellectual disability, aphasia following stroke, but excluding progressive conditions and those solely related to sensory impairments of hearing or vision. Results revealed six core strategies suggested to improve communication in hospital: (a) develop services, systems, and policies that support improved communication, (b) devote enough time to communication, (c) ensure adequate access to communication tools (nurse call systems and communication aids), (d) access personally held written health information, (e) collaborate effectively with carers, spouses, and parents, and (f) increase the communicative competence of hospital staff. Currently there are no reports that trial or validate any of these strategies specifically in hospital settings. Observational and evaluative research is needed to investigate the ecological validity of strategies proposed to improve communication. PMID:25229213

    The technical feasibility and economic viability of satellite system architectures that are suitable for customer premise service (CPS) communications are investigated. System evaluation is performed at 30/20 GHz (Ka-band); however, the system architectures examined are equally applicable to 14/11 GHz (Ku-band). Emphasis is placed on systems that permit low-cost user terminals. Frequency division multiple access (FDMA) is used on the uplink, with typically 10,000 simultaneous accesses per satellite, each of 64 kbps. Bulk demodulators onboard the satellite, in combination with a baseband multiplexer, convert the many narrowband uplink signals into a small number of wideband data streams for downlink transmission. Single-hop network interconnectivity is accomplished via downlink scanning beams. Each satellite is estimated to weigh 5600 lb and consume 6850W of power; the corresponding payload totals are 1000 lb and 5000 W. Nonrecurring satellite cost is estimated at $110 million, with the first-unit cost at $113 million. In large quantities, the user terminal cost estimate is $25,000. For an assumed traffic profile, the required system revenue has been computed as a function of the internal rate of return (IRR) on invested capital. The equivalent user charge per-minute of 64-kbps channel service has also been determined.

    The satellite switched frequency division multiple access system provided a detailed system architecture that supports a point to point communication system for long haul voice, video and data traffic between small Earth terminals at Ka band frequencies at 30/20 GHz. A detailed system design is presented for the space segment, small terminal/trunking segment at network control segment for domestic traffic model A or B, each totaling 3.8 Gb/s of small terminal traffic and 6.2 Gb/s trunk traffic. The small terminal traffic (3.8 Gb/s) is emphasized, for the satellite router portion of the system design, which is a composite of thousands of Earth stations with digital traffic ranging from a single 32 Kb/s CVSD voice channel to thousands of channels containing voice, video and data with a data rate as high as 33 Mb/s. The system design concept presented, effectively optimizes a unique frequency and channelization plan for both traffic models A and B with minimum reorganization of the satellite payload transponder subsystem hardware design. The unique zoning concept allows multiple beam antennas while maximizing multiple carrier frequency reuse. Detailed hardware design estimates for an FDMA router (part of the satellite transponder subsystem) indicate a weight and dc power budget of 353 lbs, 195 watts for traffic model A and 498 lbs, 244 watts for traffic model B.

  8. Advanced Communication Technology Satellite (ACTS) multibeam antenna analysis and experiment

    1992-01-01

    One of the most important aspects of a satellite communication system design is the accurate estimation of antenna performance degradation. Pointing error, end coverage gain, peak gain degradation, etc. are the main concerns. The thermal or dynamic distortions of a reflector antenna structural system can affect the far-field antenna power distribution in a least four ways. (1) The antenna gain is reduced; (2) the main lobe of the antenna can be mispointed thus shifting the destination of the delivered power away from the desired locations; (3) the main lobe of the antenna pattern can be broadened, thus spreading the RF power over a larger area than desired; and (4) the antenna pattern sidelobes can increase, thus increasing the chances of interference among adjacent beams of multiple beam antenna system or with antenna beams of other satellites. The in-house developed NASA Lewis Research Center thermal/structural/RF analysis program was designed to accurately simulate the ACTS in-orbit thermal environment and predict the RF antenna performance. The program combines well establish computer programs (TRASYS, SINDA and NASTAN) with a dual reflector-physical optics RF analysis program. The ACTS multibeam antenna configuration is analyzed and several thermal cases are presented and compared with measurements (pre-flight).

  11. Next generation information communication infrastructure and case studies for future power systems

    NASA Astrophysics Data System (ADS)

    Qiu, Bin

    As power industry enters the new century, powerful driving forces, uncertainties and new functions are compelling electric utilities to make dramatic changes in their information communication infrastructure. Expanding network services such as real time measurement and monitoring are also driving the need for more bandwidth in the communication network. These needs will grow further as new remote real-time protection and control applications become more feasible and pervasive. This dissertation addresses two main issues for the future power system information infrastructure: communication network infrastructure and associated power system applications. Optical networks no doubt will become the predominant data transmission media for next generation power system communication. The rapid development of fiber optic network technology poses new challenges in the areas of topology design, network management and real time applications. Based on advanced fiber optic technologies, an all-fiber network is investigated and proposed. The study will cover the system architecture and data exchange protocol aspects. High bandwidth, robust optical networks could provide great opportunities to the power system for better service and efficient operation. In the dissertation, different applications are investigated. One of the typical applications is the SCADA information accessing system. An Internet-based application for the substation automation system will be presented. VLSI (Very Large Scale Integration) technology is also used for one-line diagrams auto-generation. High transition rate and low latency optical network is especially suitable for power system real time control. In the dissertation, a new local area network based Load Shedding Controller (LSC) for isolated power system will be presented. By using PMU (Phasor Measurement Unit) and fiber optic network, an AGE (Area Generation Error) based accurate wide area load shedding scheme will also be proposed. The objective

  12. Exploring Local Approaches to Communicating Global Climate Change Information

    NASA Astrophysics Data System (ADS)

    Stevermer, A. J.

    2002-12-01

    Expected future climate changes are often presented as a global problem, requiring a global solution. Although this statement is accurate, communicating climate change science and prospective solutions must begin at local levels, each with its own subset of complexities to be addressed. Scientific evaluation of local changes can be complicated by large variability occurring over small spatial scales; this variability hinders efforts both to analyze past local changes and to project future ones. The situation is further encumbered by challenges associated with scientific literacy in the U.S., as well as by pressing economic difficulties. For people facing real-life financial and other uncertainties, a projected ``1.4 to 5.8 degrees Celsius'' rise in global temperature is likely to remain only an abstract concept. Despite this lack of concreteness, recent surveys have found that most U.S. residents believe current global warming science, and an even greater number view the prospect of increased warming as at least a ``somewhat serious'' problem. People will often be able to speak of long-term climate changes in their area, whether observed changes in the amount of snow cover in winter, or in the duration of extreme heat periods in summer. This work will explore the benefits and difficulties of communicating climate change from a local, rather than global, perspective, and seek out possible strategies for making less abstract, more concrete, and most importantly, more understandable information available to the public.

  13. Intelligent communication systems sensor scheduling based on network information

    NASA Astrophysics Data System (ADS)

    2004-04-01

    Increased reliance on data communications has driven the need for a higher capacity solution to transmit data. Many decision making problems include various types of data (i.e. video, text), which require an intelligent way to transfer the data across a communication system. Data fusion can be performed at the transmitting end to reduce the dimensionality of the data transferred; however if there are errors, the receiving end would have no way to search through the pedigree of information to correct the problem. Thus, a desired analysis is to be able to transfer all the data types, while achieving the "Quality of Service" metrics of throughput, delay, delay variation, probability of error, and cost. One way to solve this problem is by using the Asynchronous Transfer Mode network data scheduling. An ATM network allows multiple types of data to be sent over the same system with dynamic bandwidth allocation. The following paper provides a description of an intelligent scheduling model to enhance the capability to transmit data for fusion analysis.

  14. Virtualizing intimacy: information communication technologies and transnational families in therapy.

    PubMed

    Bacigalupe, Gonzalo; Lambe, Susan

    2011-03-01

    Information communication technologies (ICTs) are a ubiquitous feature of immigrant family life. Affordable, widely accessible, and highly adaptable ICTs have transformed the immigrant experience into a transnational process with family networks redesigned but not lost. Being a transnational family is not a new phenomenon. Transnationalism, however, has historically been reserved for the wealthier professional and political immigrant class who were able to freely travel and use expensive forms of communication before the emergence of accessible technologies. This paper systematically reviews the research literature to investigate the potential impact of ICTs on the lives of transnational families and how these families utilize them. The wide penetration of ICTs also puts into question some of the ways in which scholars have conceptualized the immigrant experience. The appropriate use of technology in family therapy should strengthen culturally competent and equity-based approaches to address the needs of these families. A family therapy with a transnational family illuminates some of the potential that these technologies introduce in the practice of relational clinicians.

    2008-02-01

    The use of technologies is more common in daily life; working with technologies might be associated with positive experiences such as flow. However, there is little empirical research on flow experiences in technology settings. The main aim of this study was to confirm the three-dimensional construct of flow, i.e., absorption, enjoyment, and intrinsic interest, among 517 Information and Communication Technology users [234 students whose mean age was 23 yr. (SD = 3.8)] from different areas of study, mainly Law, Public Administration, Chemistry, and Psychology, and 283 employees [whose mean age was 33 yr. (SD = 7.8)] of 21 different companies from various sectors of production, namely, public administration, industrial production, and services. Analysis showed, as expected, flow is a three-dimensional psychological construct and invariant among samples of technology users. Practical and theoretical implications as well as further research are discussed.

    Despite the well-known advantages of information and communication technologies (ICTs), their overall impact on nursing care has not been synthesized. The objective of this overview of systematic reviews is to summarize the best evidence regarding the effects of ICTs on nursing care. We considered quantitative, qualitative and mixed-method reviews published since January 1995. Two reviewers independently screened the title and abstract of 5515 papers to assess their eligibility. From these, 72 full-text papers were evaluated and 28 publications met the inclusion criteria. Three reviewers extracted and compared their data. Preliminary results show that the following dimensions of nursing care are the most frequently reported: assessment, care planning and evaluation, documentation time, quality of care and patient safety. This overview provides a starting point from which to compare and contrast findings of separate reviews regarding the positive, neutral and negative effects of ICTs on nursing care.

  20. Communication and information barriers to health assistance for deaf patients.

    PubMed

    Pereira, Patrícia Cristina Andrade; Fortes, Paulo Antonio de Carvalho

    2010-01-01

    In Brazil, recent regulations require changes in private and public health systems to make special services available to deaf patients. In the present article, the researchers analyze the perceptions of 25 sign language-using patients regarding this assistance. The researchers found communication difficulties between these patients and health services staff, as well as a culture clash and a harmful inability among the service providers to distinguish among the roles of companions, caretakers, and professional translator/interpreters. Thus, it became common for the patients to experience prejudice in the course of treatment and information exchange, damage to their autonomy, limits on their access to services, and reduced efficacy of therapy. The researchers conclude that many issues must be dealt with if such barriers to health access are to be overcome, in particular the worrying degree of exclusion of deaf patients from health care systems.

  3. Myths about older people's use of information and communication technology.

    2012-01-01

    This paper discusses six myths common in the field of 'human-computer interaction (HCI) and older people'. These myths are widespread among computer scientists, engineers and programmers, as well as among the general public and even older individuals themselves. We can define these myths as follows. (1) Just wait and see. Future generations of older people will use computers without problems. This myth differs from those following, as it may lead to a (dangerous) conclusion of avoidance and inactivity by integrating myths 2-6. If the other myths are accepted as being true and one assumes that the problems will eventually solve themselves, it might not seem worthwhile to expend any effort on 'universal design' for older people's use of information and communication technology (ICT). However, we argue that if we do not actively and properly counteract these myths, we will perpetuate them and their grave consequences. (2) Older people are not interested in using computers. They are unaware of computer capabilities. (3) Older people consider computers as useless and unnecessary. (4) Older people lack the physical capabilities to use ICT. (5) Older people simply cannot understand interactive computing technology. (6) You can't teach an old dog new tricks. The problem of HCI for older people is that they do not learn to use new technologies and interaction techniques. In discussing these myths, we demonstrate that each one contains a grain of truth. However, the myths are improperly overgeneralized and, therefore, often wrong. Such myths are problematic. Designers and engineers often accept them as truths and neglect older users and/or apply information and communication technologies in an age-discriminating manner. Furthermore, the myths are problematic as they lead older people to avoid computer usage (i.e. a self-fulfilling prophecy). We present evidence to support the notion that these myths may often be largely - although not completely - wrong. We then demonstrate

    Despite the high costs involved and the lack of definitive evidence of sustained effectiveness, many low- and middle-income countries had begun to strengthen their health information system using information and communication technology in the past few decades. Following this international trend, the Malaysian Ministry of Health had been incorporating Telehealth (National Telehealth initiatives) into national health policies since the 1990s. Employing qualitative approaches, including key informant interviews and document review, this study examines the agenda-setting processes of the Telehealth policy using Kingdon's framework. The findings suggested that Telehealth policies emerged through actions of policy entrepreneurs within the Ministry of Health, who took advantage of several simultaneously occurring opportunities--official recognition of problems within the existing health information system, availability of information and communication technology to strengthen health information system and political interests surrounding the national Multimedia Super Corridor initiative being developed at the time. The last was achieved by the inclusion of Telehealth as a component of the Multimedia Super Corridor.

    The objective of this research project is to demonstrate sensing, communication, information and control technologies to achieve a seamless integration of multivendor distributed energy resource (DER) units at aggregation levels that meet individual user requirements for facility operations (residential, commercial, industrial, manufacturing, etc.) and further serve as resource options for electric and natural gas utilities. The fully demonstrated DER aggregation system with embodiment of communication and control technologies will lead to real-time, interactive, customer-managed service networks to achieve greater customer value. Work on this Advanced Communication and Control Project (ACCP) consists of a two-phase approach for an integrated demonstration of communication and control technologies to achieve a seamless integration of DER units to reach progressive levels of aggregated power output. Phase I involved design and proof-of-design, and Phase II involves real-world demonstration of the Phase I design architecture. The scope of work for Phase II of this ACCP involves demonstrating the Phase I design architecture in large scale real-world settings while integrating with the operations of one or more electricity supplier feeder lines. The communication and control architectures for integrated demonstration shall encompass combinations of software and hardware components, including: sensors, data acquisition and communication systems, remote monitoring systems, metering (interval revenue, real-time), local and wide area networks, Web-based systems, smart controls, energy management/information systems with control and automation of building energy loads, and demand-response management with integration of real-time market pricing. For Phase II, BPL Global shall demonstrate the Phase I design for integrating and controlling the operation of more than 10 DER units, dispersed at various locations in one or more Independent System Operator (ISO) Control Areas, at

    2007-01-01

    The purpose of this study is to describe the use of information technology by advance practice nurses. A survey of 519 graduates of the Simmons College nurse practitioner program was conducted. Areas of investigation included the nurse practitioner's use of informatics technology, perception of information technology competence, adequacy of information technology training and support in the workplace, specific information technology health functions used in the workplace, and perceived benefits of using information technology. The data on the 249 usable responses were analyzed using descriptive statistics. These analyses compare the use of information technology by type of job, specialty, years of practice, and setting of work. Results indicate that more than 90% of nurse practitioners utilize computers at work, yet a large fraction of them still have low self-perception of information technology competence, believe initial training at the work site was inadequate, and believe that academic preparation for information technology was also inadequate. There is considerable variation in these measures across nurse practitioner specialties, settings of care, job characteristics, and experience.

    2015-12-01

    J-RISQ (Japan Real-time Information System for earthquake) has been developing in NIED for appropriate first-actions to big earthquakes. When an earthquake occurs, seismic intensities (SI) are calculated first at each observation station and sent to the Data Management Center in different timing. The system begins the first estimation when the number of the stations observing the SI of 2.5 or larger exceeds the threshold amount. It estimates SI distribution, exposed population and earthquake damage on buildings by using basic data for estimation, such as subsurface amplification factors, population, and building information. It has been accumulated in J-SHIS (Japan Seismic Information Station) developed by NIED, a public portal for seismic hazard information across Japan. The series of the estimation is performed for each 250m square mesh and finally the estimated data is converted into information for each municipality. Since October 2013, we have opened estimated SI, exposed population etc. to the public through the website by making full use of maps and tables.In the previous system, we sometimes could not inspect the information of the surrounding areas out of the range suffered from strong motions, or the details of the focusing areas, and could not confirm whether the present information was the latest or not without accessing the website. J-RISQ has been advanced by introducing the following functions to settle those problems and promote utilization in local areas or in personal levels. In addition, the website in English has been released.・It has become possible to focus on the specific areas and inspect enlarged information.・The estimated information can be downloaded in the form of KML.・The estimated information can be updated automatically and be provided as the latest one.・The newest information can be inspected by using RSS readers or browsers corresponding to RSS.・Exclusive pages for smartphones have been prepared.The information estimated

    Advanced satellite sensors are tasked with improving global observations of the Earth's atmosphere, clouds, and surface to enable enhancements in weather prediction, climate monitoring capability, and environmental change detection. Satisfying this type of improvement for inferred geophysical information from these observations requires optimal usage of data from current systems as well as enhancements to future sensors. This presentation addresses the information content present in infrared spectral radiance from advanced atmospheric sounders with an emphasis on knowledge of thermodynamic state and trace species. Results of trade-off studies conducted to evaluate the impact of spectral resolution, spectral coverage, instrument noise, and a priori knowledge on remote sensing system information content will be discussed. A focus is placed on information achievable from the Atmospheric InfraRed Sounder (AIRS) on the NASA EOS Aqua satellite in orbit since 2002, the Infrared Atmospheric Sounding Interferometer (IASI) aboard MetOp-A since 2006, and the Cross-track Infrared Sounder (CrIS) instrument aboard the NPP and JPSS series of satellites which began 28 October 2011.

    NASA's Earth Science Technology Office (ESTO) manages a wide range of information technology projects under the Advanced Information Systems Technology (AIST) Program. The AIST Program aims to support all phases of NASA's Earth Science program with the goal of enabling new observations and information products, increasing the accessibility and use of Earth observations, and reducing the risk and cost of satellite and ground based information systems. Recent initiatives feature computational technologies to improve information extracted from data streams or model outputs and researchers' tools for Big Data analytics. Data-centric technologies enable research communities to facilitate collaboration and increase the speed with which results are produced and published. In the future NASA anticipates more small satellites (e.g., CubeSats), mobile drones and ground-based in-situ sensors will advance the state-of-the-art regarding how scientific observations are performed, given the flexibility, cost and deployment advantages of new operations technologies. This paper reviews the success of the program and the lessons learned. Infusion of these technologies is challenging and the paper discusses the obstacles and strategies to adoption by the earth science research and application efforts. It also describes alternative perspectives for the future program direction and for realizing the value in the steps to transform observations from sensors to data, to information, and to knowledge, namely: sensor measurement concepts development; data acquisition and management; data product generation; and data exploitation for science and applications.

    2008-12-01

    Being a science teach once was about transferring information to students; now it is understood that concepts are better learned when students become invested in their learning through investigation and adventure learning (AL). Since most K-12 science teachers have little time to conduct their own research, and many researchers are not trained at teaching - a vacuum is formed between the scientists and teachers/students. Liaison materials are therefore required for effective teaching. Wonderful teacher trainings and well-designed labs/interactive curriculum are starting to fill in the gap. Indeed, while students are growing new limbs: knowledge and perspective, yet they may be missing the one of the drivers behind science: the vitality and purpose engendered when one helps close in, two steps forward/one step back, on one of the ever-present unknowns in or new perspective on a timely study or issue. Since there are mandates that both NSF and NASA funded grants have outreach components, the void becomes opportunity. This is where the numerous applications of the technology (e.g. high-speed internet; video conferencing; blogging; video/animation illustrations, and student collection of and reporting on data) are coming to life. However, to take full advantage of this asset scientists and teachers need liaisons - companies; corners of an institute or department, or individuals who facilitate connections between educators and willing scientists, data, learning tools or otherwise. It is truly an enterprising time when the science community is able to explore the delivery of Adventure Learning, in ways that grow in number by the day. This presentation sites and uses examples of what are effective/unique mechanisms for bringing students all the more closer to science and business possibilities where the vacuum remains gaping.

  10. Advancing the art of satellite communications - Foreign competition spurs NASA Satcom research

    NASA Astrophysics Data System (ADS)

    Bulloch, C.

    1985-01-01

    Major advances in satellite communications technology in the US and Japan are detailed. Japan's Ka-band services aboard CS-2a and CS-2b, launched in 1973, are discussed, as well as plans for the ECS-2 and ACTS-E (Advanced Communications Technology Satellite) experimental projects. The ACTS-E would carry both a broadcasting payload operating at 27/22 GHz and a communication payload using the 50/40 GHz band. Japan's fourth generation CS-4, for start-up in the first half of the 1990's, is described as a 2-ton craft carrying 60-70 transponders, and providing capacity for up to 100,000 equivalent two-way voice channels via 10 or 20 scanning spotbeams. NASA's new programs are described as well, including the ACTS program, with a communications payload embodying signal-processing, message-routing, and traffic-management techniques, and the MSAT program, concentrating on narrow-band transmissions. Included are the technical description, operational parameters, and schematic layout of NASA's ACTS, and block diagrams of baseband processor for low burst rate communications switching on the ACTS.

  11. Advanced Communication Architectures and Technologies for Missions to the Outer Planets

    NASA Technical Reports Server (NTRS)

    Bhasin, K.; Hayden, J. L.

    2001-01-01

    Missions to the outer planets would be considerably enhanced by the implementation of a future space communication infrastructure that utilizes relay stations placed at strategic locations in the solar system. These relay stations would operate autonomously and handle remote mission command and data traffic on a prioritized demand access basis. Such a system would enhance communications from that of the current direct communications between the planet and Earth. The system would also provide high rate data communications to outer planet missions, clear communications paths during times when the sun occults the mission spacecraft as viewed from Earth, and navigational "lighthouses" for missions utilizing onboard autonomous operations. Additional information is contained in the original extended abstract.

  12. The Canterbury Tales: Lessons from the Canterbury Earthquake Sequence to Inform Better Public Communication Models

    McBride, S.; Tilley, E. N.; Johnston, D. M.; Becker, J.; Orchiston, C.

    2015-12-01

    This research evaluates the public education earthquake information prior to the Canterbury Earthquake sequence (2010-present), and examines communication learnings to create recommendations for improvement in implementation for these types of campaigns in future. The research comes from a practitioner perspective of someone who worked on these campaigns in Canterbury prior to the Earthquake Sequence and who also was the Public Information Manager Second in Command during the earthquake response in February 2011. Documents, specifically those addressing seismic risk, that were created prior to the earthquake sequence, were analyzed, using a "best practice matrix" created by the researcher, for how closely these aligned to best practice academic research. Readability tests and word counts are also employed to assist with triangulation of the data as was practitioner involvement. This research also outlines the lessons learned by practitioners and explores their experiences in regards to creating these materials and how they perceive these now, given all that has happened since the inception of the booklets. The findings from the research showed these documents lacked many of the attributes of best practice. The overly long, jargon filled text had little positive outcome expectancy messages. This probably would have failed to persuade anyone that earthquakes were a real threat in Canterbury. Paradoxically, it is likely these booklets may have created fatalism in publics who read the booklets. While the overall intention was positive, for scientists to explain earthquakes, tsunami, landslides and other risks to encourage the public to prepare for these events, the implementation could be greatly improved. This final component of the research highlights points of improvement for implementation for more successful campaigns in future. The importance of preparedness and science information campaigns can be not only in preparing the population but also into development of

    Sivertson, W. E., Jr.

    1977-01-01

    This paper briefly introduces a concept for low-cost, global, day-night, all-weather disaster warning and assistance. Evolving, advanced space technology with passive radio frequency reflectors in conjunction with an imaging synthetic aperture radar is employed to detect, identify, locate, and provide passive communication with earth users in distress. This concept evolved from a broad NASA research on new global search and rescue techniques. Appropriate airborne radar test results from this research are reviewed and related to potential disaster applications. The analysis indicates the approach has promise for disaster communications relative to floods, droughts, earthquakes, volcanic eruptions, and severe storms.

  17. Impact of Measurement System Characteristics on Advanced Sounder Information Content

    NASA Technical Reports Server (NTRS)

    Larar, Allen M.; Liu, Xu; Zhou, Daniel K.

    2011-01-01

    Advanced satellite sensors are tasked with improving global observations of the Earth's atmosphere, clouds, and surface to enable enhancements in weather prediction, climate monitoring capability, and environmental change detection. Achieving such an improvement in geophysical information inferred from these observations requires optimal usage of data from current systems as well as instrument system enhancements for future sensors. This presentation addresses results of tradeoff studies evaluating the impact of spectral resolution, spectral coverage, instrument noise, and a priori knowledge on remote sensing system information content, with a specific emphasis on thermodynamic state and trace species information obtainable from advanced atmospheric sounders. Particular attention will be devoted toward information achievable from the Atmospheric InfraRed Sounder (AIRS) on the NASA EOS Aqua satellite in orbit since 2002, the Infrared Atmospheric Sounding Interferometer (IASI) aboard MetOp-A since 2006, and the Cross-track Infrared Sounder (CrIS) instrument to fly aboard the NPP and JPSS series of satellites expected to begin in late 2011. While all of these systems cover nearly the same infrared spectral extent, they have very different number of channels, instrument line shapes, coverage continuity, and instrument noise. AIRS is a grating spectrometer having 2378 discrete spectral channels ranging from about 0.4 to 2.2/cm resolution; IASI is a Michelson interferometer with 8461 uniformly-spaced spectral channels of 0.5/cm (apodized) resolution; and CrIS is a Michelson interferometer having 1305 spectral channels of 0.625, 1.250, and 2.50/cm (unapodized) spectral resolution, respectively, over its three continuous but non-overlapping bands. Results of tradeoff studies showing information content sensitivity to assumed measurement system characteristics will be presented.

    Objective To investigate the cognitive and neural correlates of discourse impairment in corticobasal syndrome (CBS). Background Difficulty communicating is a frequent clinical manifestation in patients with CBS. However, the mechanisms underlying this disabling problem are not well understood. Methods Twenty patients with CBS and 8 healthy seniors narrated a picture story. Narratives were analyzed for maintenance of the narrative theme, identification of the overall point of the story (global connectedness), and connectedness between consecutive events (local connectedness). Discourse measures were correlated with performance on cognitive tasks and with cortical atrophy as determined by magnetic resonance imaging voxel-based morphometry. Results Patients with CBS referred to the narrative theme significantly less frequently than controls. Global connectedness was intact in only 6 of 20 CBS patients (30%), but preserved in all controls. Local connectedness was significantly diminished in patients relative to controls. Discourse performance in CBS was related to tasks requiring higher-order integration of visual material, but not to basic visuospatial/visuoperceptual, language, or memory function. Discourse impairment was directly related to atrophy in the right parietal lobe and bilateral dorsolateral prefrontal cortex. Conclusions Our findings suggest that impaired information integration in CBS, related to parieto-frontal disease, interferes with patients’ ability to narrate a coherent story. PMID:20299856

    The relationship between use of information and communication technologies (ICTs) and well-being is an increasingly debated public health issue. Currently, there is limited understanding of how the ethnic digital divide influences this association. Thus, this study assessed how ethnicity has historically moderated relations between ICT (mobile phone, computer, and TV) uptake, and several well-being indicators: (a) long-term health (chronic illness), (b) cigarette smoking, and (c) self-perceptions of personal health. Archived data from a U.K. Office for National Statistics household survey 2007-2011 (97,697 participant records) were analyzed, controlling for multiple sociodemographic confounders. Mobile phone dependence was associated with poorer health perceptions in Caucasian women, but more favorable appraisals in ethnic minority females (OR = 0.51). Furthermore, mobile phone uptake was more strongly related to increased behavioral risk (cigarette smoking) in Caucasian men compared with ethnic minority males (OR = 1.68). Ethnicity did not influence relations between ICT uptake and long-term health. Overall, ethnicity was implicated in relations between mobile phone use and well-being indicators: unfavorable associations occurred primarily in Caucasians.

  1. Ubiquitous Diabetes Management System via Interactive Communication Based on Information Technologies: Clinical Effects and Perspectives

    New diabetes management systems based on interactive communication have been introduced recently, accompanying rapid advances in information technology; these systems are referred to as "ubiquitous diabetes management systems." In such ubiquitous systems, patients and medical teams can communicate via Internet or telecommunications, with patients uploading their glucose data and personal information, and medical teams sending optimal feedback. Clinical evidence from both long-term and short-term trials has been reported by some researchers. Such systems appear to be effective not only in reducing the levels of HbA1c but also in stabilizing glucose control. However, most notably, evidence for the cost-effectiveness of such a system should be demonstrated before it can be propagated out to the general population in actual clinical practice. To establish a cost-effective model, various types of clinical decision supporting software designed to reduce the labor time of physicians must first be developed. A number of sensors and devices for monitoring patients' data are expected to be available in the near future; thus, methods for automatic interconnections between devices and web charts were also developed. Further investigations to demonstrate the clinical outcomes of such a system should be conducted, hopefully leading to a new paradigm of diabetes management. PMID:21076573

    Inappropriate speed is a relevant concurrent factor in many traffic accidents. Moreover, in recent years, traffic accidents numbers in Spain have fallen sharply, but this reduction has not been so significant on single carriageway roads. These infrastructures have less equipment than high-capacity roads, therefore measures to reduce accidents on them should be implemented in vehicles. This article describes the development and analysis of the impact on the driver of a warning system for the safe speed on each road section in terms of geometry, the presence of traffic jams, weather conditions, type of vehicle and actual driving conditions. This system is based on an application for smartphones and includes knowledge of the vehicle position via Ground Positioning System (GPS), access to intravehicular information from onboard sensors through the Controller Area Network (CAN) bus, vehicle data entry by the driver, access to roadside information (short-range communications) and access to a centralized server with information about the road in the current and following sections of the route (long-range communications). Using this information, the system calculates the safe speed, recommends the appropriate speed in advance in the following sections and provides warnings to the driver. Finally, data are sent from vehicles to a server to generate new information to disseminate to other users or to supervise drivers’ behaviour. Tests in a driving simulator have been used to define the system warnings and Human Machine Interface (HMI) and final tests have been performed on real roads in order to analyze the effect of the system on driver behavior.

    1994-01-01

    This program demonstrated the integration of a number of technologies that can increase the availability and reliability of launch vehicles while lowering costs. Availability is increased with an advanced guidance algorithm that adapts trajectories in real-time. Reliability is increased with fault-tolerant computers and communication protocols. Costs are reduced by automatically generating code and documentation. This program was realized through the cooperative efforts of academia, industry, and government. The NASA-LaRC coordinated the effort, while Draper performed the integration. Georgia Institute of Technology supplied a weak Hamiltonian finite element method for optimal control problems. Martin Marietta used MATLAB to apply this method to a launch vehicle (FENOC). Draper supplied the fault-tolerant computing and software automation technology. The fault-tolerant technology includes sequential and parallel fault-tolerant processors (FTP & FTPP) and authentication protocols (AP) for communication. Fault-tolerant technology was incrementally incorporated. Development culminated with a heterogeneous network of workstations and fault-tolerant computers using AP. Draper's software automation system, ASTER, was used to specify a static guidance system based on FENOC, navigation, flight control (GN&C), models, and the interface to a user interface for mission control. ASTER generated Ada code for GN&C and C code for models. An algebraic transform engine (ATE) was developed to automatically translate MATLAB scripts into ASTER.

    This paper describes an initiative begun by the Advanced Technology Program in 1994 referred to as the Information Infrastructure for Healthcare (IIH) focused program. The IIH focus program began with an initial exchange of ideas among members of the private and public sectors (industry's submission of "white papers"; workshops conducted by the ATP; meetings held between individuals from both groups) to identify those technologies necessary for the development of a national information infrastructure in healthcare. A discussion of the development of the focus program through a "white paper" process notes differences that existed between what the ATP had hoped to gain through this method and how the private sector responded. A statistical description of the participants as well as a brief discussion of the ATP review and selection process is included.

    New applications of information and communication technology (ICT) are shaping the way we understand and provide humanitarian medical assistance in situations of disaster, disease outbreak or conflict. Each new crisis appears to be accompanied by advancements in humanitarian technology, leading to significant improvements in the humanitarian aid sector. However, ICTs raise ethical questions that warrant attention. Focusing on the context of humanitarian medical assistance, we review key domains of ICT innovation. We then discuss ethical challenges and uncertainties associated with the development and application of new ICTs in humanitarian medical assistance, including avoiding harm, ensuring privacy and security, responding to inequalities, demonstrating respect, protecting relationships, and addressing expectations. In doing so, we emphasize the centrality of ethics in humanitarian ICT design, application and evaluation.

    Taft, Jeffrey D.; Becker-Dippmann, Angela S.

    2015-08-01

    This paper examines the implications of emerging interdependencies between the electric power grid and Information and Communication Technology (ICT). Over the past two decades, electricity and ICT infrastructure have become increasingly interdependent, driven by a combination of factors including advances in sensor, network and software technologies and progress in their deployment, the need to provide increasing levels of wide-area situational awareness regarding grid conditions, and the promise of enhanced operational efficiencies. Grid operators’ ability to utilize new and closer-to-real-time data generated by sensors throughout the system is providing early returns, particularly with respect to management of the transmission system for purposes of reliability, coordination, congestion management, and integration of variable electricity resources such as wind generation.

    This paper describes current progress for an information management project in a medium-sized rural hospital after the first four months of the one-year project. In particular, the article examines some of the project outcomes to date as these relate to the National Hospitals and Health Reform recommendations for the smart use of data, information and communication. The paper identifies a number of important challenges and issues that have been addressed by the project and proposes that the project findings may be used to inform similar projects in other settings. These findings relate to clinician requirements for reports, investment in human resources, development, and time for information management activities. An understanding of data collected, information systems, and presentation of clinician data are also important. The benefits of information sharing in assisting quality improvement activities are particularly relevant but, more importantly, they can engage and involve clinicians in the use of information. The importance of local data, information, and knowledge is described. Finally, issues for the health information management profession, such as working collegially and sharing knowledge and expertise, are outlined.

    2003-01-01

    An On-line Technology Information System (OTIS) is currently being developed for the Advanced Life Support (ALS) Program. This paper describes the preliminary development of OTIS, which is a system designed to provide centralized collection and organization of technology information. The lack of thorough, reliable and easily understood technology information is a major obstacle in effective assessment of technology development progress, trade studies, metric calculations, and technology selection for integrated testing. OTIS will provide a formalized, well-organized protocol to communicate thorough, accurate, current and relevant technology information between the hands-on technology developer and the ALS Community. The need for this type of information transfer system within the Solid Waste Management (SWM) element was recently identified and addressed. A SWM Technology Information Form (TIF) was developed specifically for collecting detailed technology information in the area of SWM. In the TIF, information is requested from SWM technology developers, based upon the Technology Readiness Level (TRL). Basic information is requested for low-TRL technologies, and more detailed information is requested as the TRL of the technology increases. A comparable form is also being developed for the wastewater processing element. In the future, similar forms will also be developed for the ALS elements of air revitalization, food processing, biomass production and thermal control. These ALS element-specific forms will be implemented in OTIS via a web-accessible interface,with the data stored in an object-oriented relational database (created in MySQLTM) located on a secure server at NASA Ames Research Center. With OTIS, ALS element leads and managers will be able to carry out informed research and development investment, thereby promoting technology through the TRL scale. OTIS will also allow analysts to make accurate evaluations of technology options. Additionally, the range

    An Advanced Imaging Communication System (AICS) was proposed in the mid-1970s as an alternative to the Voyager data/communication system architecture. The AICS achieved virtually error free communication with little loss in the downlink data rate by concatenating a powerful Reed-Solomon block code with the Voyager convolutionally coded, Viterbi decoded downlink channel. The clean channel allowed AICS sophisticated adaptive data compression techniques. Both Voyager and the Galileo mission have implemented AICS components, and the concatenated channel itself is heading for international standardization. An analysis that assigns a dollar value/cost savings to AICS mission performance gains is presented. A conservative value or savings of $3 million for Voyager, $4.5 million for Galileo, and as much as $7 to 9.5 million per mission for future projects such as the proposed Mariner Mar 2 series is shown.

    The production of new knowledge in augmentative and alternative communication (AAC) requires effective processes to leverage the different perspectives of researchers and knowledge users and improve prospects for utilization in clinical settings. This article describes the motivation, planning, process, and outcomes for a novel knowledge translation workshop designed to influence future directions for AAC outcomes research for children with complex communication needs. Invited knowledge users from 20 pediatric AAC clinics and researchers engaged in the collaborative development of research questions using a framework designed for the AAC field. The event yielded recommendations for research and development priorities that extend from the early development of language, communication, and literacy skills in very young children, to novel but unproven strategies that may advance outcomes in transitioning to adulthood.

    The Integrated Ocean Observing System (IOOS) represents a national initiative to create a new system for collecting and disseminating information about the oceans. The system will support a variety of practical applications, along with enabling research. A key partner in IOOS design and development, the Southeastern Universities Research Association (SURA) is a consortium of over sixty universities across the US. Building on the capabilities of its member universities, SURA seeks to develop a network of sensors and linked computers as part of the SURA Coastal Ocean Observing and Prediction (SCOOP) program, fully integrating several observing systems in the southern US. SCOOP's goal is to create a scalable, modular prediction system for storm surge and wind waves. The system will enable a "transition to operations" of cutting-edge modeling activities from the research community. This network will provide data in real-time and at high speed, for more reliable, accurate and timely information to help guide effective coastal stewardship, plan for extreme events, facilitate safe maritime operations, and support coastal security. The University of Alabama in Huntsville is developing a suite of advanced technologies to provide core data and information management services for SCOOP. This Scientific Catalog for Open Resource Exchange (SCORE) is built on UAH's information technology research for a variety of projects, including the NASA- funded Global Hydrology Resource Center and DISCOVER REASoN projects, NSF-funded Linked Environments for Atmospheric Discovery (LEAD) large Information Technology Research project, as well as for SCOOP, which is funded by NOAA and ONR. Key technologies include an extensible database schema and ontology for the target science domain. Web services provide low level catalog access, while an integrated search capability includes semantic searching and browsing, with the potential for specialized, innovative interfaces for specific research

  4. Known unknowns: indirect energy effects of information and communication technology

    NASA Astrophysics Data System (ADS)

    Horner, Nathaniel C.; Shehabi, Arman; Azevedo, Inês L.

    2016-10-01

    Background. There has been sustained and growing interest in characterizing the net energy impact of information and communication technology (ICT), which results from indirect effects offsetting (or amplifying) the energy directly consumed by ICT equipment. These indirect effects may be either positive or negative, and there is considerable disagreement as to the direction of this sign as well as the effect magnitude. Literature in this area ranges from studies focused on a single service (such as e-commerce versus traditional retail) to macroeconomic studies attempting to characterize the overall impact of ICT. Methods. We review the literature on the indirect energy effect of ICT found via Google Scholar, our own research, and input from other researchers in the field. The various studies are linked to an effect taxonomy, which is synthesized from several different hierarchies present in the literature. References are further grouped according to ICT service (e.g., e-commerce, telework) and summarized by scope, method, and quantitative and qualitative findings. Review results. Uncertainty persists in understanding the net energy effects of ICT. Results of indirect energy effect studies are highly sensitive to scoping decisions and assumptions made by the analyst. Uncertainty increases as the impact scope broadens, due to complex and interconnected effects. However, there is general agreement that ICT has large energy savings potential, but that the realization of this potential is highly dependent on deployment details and user behavior. Discussion. While the overall net effect of ICT is likely to remain unknown, this review suggests several guidelines for improving research quality in this area, including increased data collection, enhancing traditional modeling studies with sensitivity analysis, greater care in scoping, less confidence in characterizing aggregate impacts, more effort on understanding user behavior, and more contextual integration across the

    2016-01-01

    Background Hospitalization of a neonate in the neonatal intensive care unit (NICU) can be a stressful event for parents. They need specific information and communication to alleviate their stress, but these parental needs are not met by NICU staff. Exploration of these needs can help health professionals to provide better healthcare services. Objectives The purpose of this study was to explore the information and communication needs of families in neonatal end-of-life and bereavement in the NICU. Materials and Methods A qualitative content analysis method was used for this study. Data were collected through single semi-structured interviews with 24 participants. Sampling was conducted based on the purposive sampling method in five NICU environments in Iran. All interviews were taped and transcribed verbatim. Results Data analysis revealed two main themes: information and communication. For information, there were two subthemes (true information about the infant’s health and true information about the infant’s death), and communication needs also developed two subthemes (communication with healthcare professionals and communication with the infant before, during and after the infant’s death). Conclusions According to the results, parents need accurate information about the health and the death of their neonates in the NICU. They also need to communicate with healthcare professionals and their babies. Communication is regarded as a channel for obtaining information. Therefore, the healthcare team needs to address these families’ needs and attempt to fulfill their requirements in neonatal end-of-life and bereavement in the NICU. PMID:27621926

    2004-01-01

    The rhizosphere is a densely populated area in which plant roots must compete with invading root systems of neighboring plants for space, water, and mineral nutrients, and with other soil-borne organisms, including bacteria and fungi. Root-root and root-microbe communications are continuous occurrences in this biologically active soil zone. How do roots manage to simultaneously communicate with neighboring plants, and with symbiotic and pathogenic organisms within this crowded rhizosphere? Increasing evidence suggests that root exudates might initiate and manipulate biological and physical interactions between roots and soil organisms, and thus play an active role in root-root and root-microbe communication.

    Cancer innovations, such as biobanking technologies, are continuously evolving to improve our understanding and knowledge about cancer prevention and treatment modalities. However, the public receives little communication about biobanking and is often unaware about this innovation until asked to donate biospecimens. It is the researchers' ethical duty to provide clear communications about biobanking and biospecimen research. Such information allows the public to understand biobanking processes and facilitates informed decision making about biospecimen donation. The aims of this paper are 1) to examine the importance of clear communication as an ethical imperative when conveying information about cancer innovations and 2) to illustrate the use of an organizing framework, the CLEAN ( C ulture, L iteracy, E ducation, A ssessment, and N etworking) Look approach for creating educational priming materials about the topic of biobanking.

    1984-01-01

    The system concept and requirements for an Advanced Information Processing System (AIPS) are briefly described, but the emphasis of this paper is on the evaluation methodologies being developed and utilized in the AIPS program. The evaluation tasks include hardware reliability, maintainability and availability, software reliability, performance, and performability. Hardware RMA and software reliability are addressed with Markov modeling techniques. The performance analysis for AIPS is based on queueing theory. Performability is a measure of merit which combines system reliability and performance measures. The probability laws of the performance measures are obtained from the Markov reliability models. Scalar functions of this law such as the mean and variance provide measures of merit in the AIPS performability evaluations.

    2016-04-01

    The present article aimed to provide a comprehensive review of current status of end-of-life (EOL) care and sociocultural considerations in Korea, with focus on the EOL communication and use of advance directives (AD) in elderly Koreans. Through literature review, we discuss the current status of EOL care and sociocultural considerations in Korea, and provide a look-ahead. In Korea, patients often receive life-sustaining treatment until the very end of life. Advance care planning is rare, and most do-not-resuscitate decisions are made between the family and physician at the very end of patient's life. Koreans, influenced mainly by Confucian tradition, prefer a natural death and discontinuation of life-sustaining treatment. Although Koreans generally believe that death is natural and unavoidable, they tend not to think about or discuss death, and regard preparation for death as unnecessary. As a result, AD are completed by just 4.7% of the general adult population. This situation can be explained by several sociocultural characteristics including opting for natural death, wish not to burden others, preference for family involvement and trust in doctor, avoidance of talking about death, and filial piety. Patients often receive life-sustaining treatment until the very EOL, advance care planning and the use of AD is not common in Korea. This was related to unique sociocultural characteristics of Korea. A more active role of physicians, development of a more deliberate EOL discussion process, development of culturally appropriate AD and promotion of advance care planning might be required to provide good EOL care in Korea.

    Communication flow of scientific information has been restructured with the development of new technologies and the Internet and their impact on social relations worldwide. The production of scientific knowledge has also been influenced by these cultural, social and economic changes and has contributed to new patterns of scientific communication. The objective of the study was to present the traditional scientific communication model and its evolution to electronic scientific communication stimulated by the use of electronic media and Internet and networking. While the traditional model is based on printed publications, the new one focuses on electronic publishing and open unlimited access to published literature. The challenges faced are in using all the potential of electronic media for improving traditional communication flow of scientific information and defining policies to support the new model of scientific communication to ensure quality, preservation and dissemination of information as a common good.

    Information and communication technologies are opening up vast new arenas for conducting the work of health promotion. Technology-based health promotions expand reach, standardize information and its delivery, provide opportunities for tailoring, create engaging interactivity within content delivery, provide for privacy and autonomy, improve portability, and lower delivery costs. This commentary describes the ongoing exploration and development of a web-based tool for enhancing the reach and impact of photovoice as a community change intervention. Features of the tool use information and communication technologies that integrate the use of an online learning management system, tailored messaging, gaming technology, interactive features, and the application of social media's power to increase the capacity of communities to employ comprehensive strategies to improve the health of their communities. It will enable individuals and groups to use photos and captions to assess the physical environment, social norms and behaviors of communities; raise community awareness of the factors contributing to ill-health in their communities, mobilize stakeholders, and inform environmental strategies and policy changes. We believe it will enhance the delivery of educational content about conducting photovoice projects, provide features unavailable without the application of information and communication technologies, and will be substantive advancement over existing photovoice resources.
