CONSTELL: NASA's Satellite Constellation Model
NASA Technical Reports Server (NTRS)
Theall, Jeffrey R.; Krisko, Paula H.; Opiela, John N.; McKay, Gordon A. (Technical Monitor)
1999-01-01
The CONSTELL program represents an initial effort by the orbital debris modeling group at NASA/JSC to address the particular issues and problems raised by the presence of LEO satellite constellations. It was designed to help NASA better understand the potential orbital debris consequences of having satellite constellations operating in the future in LEO. However, it could also be used by constellation planners to evaluate architecture or design alternatives that might lessen debris consequences for their constellation or lessen the debris effects on other users of space. CONSTELL is designed to perform debris environment projections rapidly so it can support parametric assessments involving either the constellations themselves or the background environment which represents non-constellation users of the space. The projections need to be calculated quickly because a number of projections are often required to adequately span the parameter space of interest. To this end CONSTELL uses the outputs of other NASA debris environment models as inputs, thus doing away with the need for time consuming upfront calculations. Specifically, CONSTELL uses EVOLVE or ORDEM96 debris spatial density results as its background environment, debris cloud snapshot templates to simulate debris cloud propagation, and time dependent orbit profiles of the intact non- functional constellation spacecraft and upper stages. In this paper the environmental consequences of the deployment of particular LEO satellite constellations using the CONSTELL model will be evaluated. Constellations that will undergo a parametric assessment will reflect realistic parameter values. Among other results the increase in loss rate of non-constellation spacecraft, the number of collisions involving constellation elements, and the replacement rate of constellation satellites as a result of debris impact will be presented.

NanoSat Constellation Mission Design
NASA Technical Reports Server (NTRS)
Concha, Marco; DeFazio, Robert
1998-01-01
The NanoSat constellation concept mission proposes simultaneous operation of multiple swarms of as many as 22 identical 10 kg spacecraft per swarm. The various orbits in a NanoSat swarm vary from 3x12 to 3x42 R(sub e) in geometry. In this report the unique flight dynamics issues of this constellation satellite mission design are addressed. Studies include orbit design, orbit determination, and error analysis. A preliminary survey determined the orbital parameters that would limit the maximum shadow condition while providing adequate ground station access for three ground stations.

2017-02-01
Recently, several announcements have been published to deploy satellite constellations into Low Earth Orbit (LEO) containing several hundred to thousands of rather small sized objects. The purpose of these constellations is to provide a worldwide internet coverage, even to the remotest areas. Examples of these mega-constellations are one from SpaceX, which is announced to comprise of about 4000 satellites, the Norwegian STEAM network, which is told to contain 4257 satellites, and the OneWeb constellation, which forms one of the smaller constellations with 720 satellites. As example constellation, OneWeb has been chosen. From all announced constellation, OneWeb by far delivered most information, both in regards to constellation design and their plans to encounter space debris issues, which is the reason why it has been chosen for these analyses. In this paper, at first an overview of the planned OneWeb constellation setup is given. From this description, a mission life-cycle is deduced, splitting the complete orbital lifetime of the satellites into four phases. Following, using ESA-MASTER, for each of the mission phases the flux on both single constellations satellites and the complete constellation are performed and the collision probabilities are derived. The focus in this analysis is set on catastrophic collisions. This analysis is then varied parametrically for different operational altitudes of the constellation as well as different lifetimes with different assumptions for the success of post mission disposal (PMD). Following the to-be-expected mean number of collision avoidance manoeuvres during all active mission phases is performed using ARES from ESA's DRAMA tool suite. The same variations as during the flux analysis are considered. Lastly the characteristics of hypothetical OneWeb satellite fragmentation clouds, calculated using the NASA Breakup model, are described and the impact of collision clouds from OneWeb satellites on the constellation itself is analysed.

In October 2002 the federal government issued a draft "Compliance Program Guidance for Pharmaceutical Manufacturers." The draft Guidance questioned the legality of many arrangements heretofore left to the discretion of physicians and drug companies, including industry-funded educational and research grants, consultantcies, and gifts. Medical organizations and drug manufacturers proposed major revisions to the draft, arguing that current practices were in everyone's best interest. To evaluate the impact of their responses, we compare the draft, the changes requested by industry and organized medicine, and the final Guidance document (issued in April 2003). We also explore the implications--some intended, others unanticipated--of the final document.

The CEOS constellation for land surface imaging
Bailey, G.B.; Berger, Marsha; Jeanjean, H.; Gallo, K.P.
2007-01-01
A constellation of satellites that routinely and frequently images the Earth's land surface in consistently calibrated wavelengths from the visible through the microwave and in spatial detail that ranges from sub-meter to hundreds of meters would offer enormous potential benefits to society. A well-designed and effectively operated land surface imaging satellite constellation could have great positive impact not only on the quality of life for citizens of all nations, but also on mankind's very ability to sustain life as we know it on this planet long into the future. The primary objective of the Committee on Earth Observation Satellites (CEOS) Land Surface Imaging (LSI) Constellation is to define standards (or guidelines) that describe optimal future LSI Constellation capabilities, characteristics, and practices. Standards defined for a LSI Constellation will be based on a thorough understanding of user requirements, and they will address at least three fundamental areas of the systems comprising a Land Surface Imaging Constellation: the space segments, the ground segments, and relevant policies and plans. Studies conducted by the LSI Constellation Study Team also will address current and shorter-term problems and issues facing the land remote sensing community today, such as seeking ways to work more cooperatively in the operation of existing land surface imaging systems and helping to accomplish tangible benefits to society through application of land surface image data acquired by existing systems. 2007 LSI Constellation studies are designed to establish initial international agreements, develop preliminary standards for a mid-resolution land surface imaging constellation, and contribute data to a global forest assessment.

Human Systems Integration in Practice: Constellation Lessons Learned
NASA Technical Reports Server (NTRS)
Zumbado, Jennifer Rochlis
2012-01-01
NASA's Constellation program provided a unique testbed for Human Systems Integration (HSI) as a fundamental element of the Systems Engineering process. Constellation was the first major program to have HSI mandated by NASA's Human Rating document. Proper HSI is critical to the success of any project that relies on humans to function as operators, maintainers, or controllers of a system. HSI improves mission, system and human performance, significantly reduces lifecycle costs, lowers risk and minimizes re-design. Successful HSI begins with sufficient project schedule dedicated to the generation of human systems requirements, but is by no means solely a requirements management process. A top-down systems engineering process that recognizes throughout the organization, human factors as a technical discipline equal to traditional engineering disciplines with authority for the overall system. This partners with a bottoms-up mechanism for human-centered design and technical issue resolution. The Constellation Human Systems Integration Group (HSIG) was a part of the Systems Engineering and Integration (SE&I) organization within the program office, and existed alongside similar groups such as Flight Performance, Environments & Constraints, and Integrated Loads, Structures and Mechanisms. While the HSIG successfully managed, via influence leadership, a down-and-in Community of Practice to facilitate technical integration and issue resolution, it lacked parallel top-down authority to drive integrated design. This presentation will discuss how HSI was applied to Constellation, the lessons learned and best practices it revealed, and recommendations to future NASA program and project managers. This presentation will discuss how Human Systems Integration (HSI) was applied to NASA's Constellation program, the lessons learned and best practices it revealed, and recommendations to future NASA program and project managers on how to accomplish this critical function.

End-of-Mission Planning Challenges for a Satellite in a Constellation
NASA Technical Reports Server (NTRS)
Boain, Ronald J.
2013-01-01
At the end of a mission, satellites embedded in a constellation must first perform propulsive maneuvers to safely exit the constellation before they can begin with the usual end-of-mission activities: deorbit, passivation, and decommissioning. The target orbit for these exit maneuvers must be sufficiently below the remaining constellation satellites such that, once achieved, there is no longer risk of close conjunctions. Yet, the exit maneuvers must be done based on the spacecraft's state of health and operational capability when the decision to end the mission is made. This paper focuses on the recently developed exit strategy for the CloudSat mission to highlight problems and issues, which forced the discarding of CloudSat's original EoM Plan and its replacement with a new plan consistent with changes to the spacecraft's original operational mode. The analyses behind and decisions made in formulating this new exit strategy will be of interest to other missions in a constellation currently preparing to update their End-of-Mission Plan.

Error Reduction Analysis and Optimization of Varying GRACE-Type Micro-Satellite Constellations
NASA Astrophysics Data System (ADS)
Widner, M. V., IV; Bettadpur, S. V.; Wang, F.; Yunck, T. P.
2017-12-01
The Gravity Recovery and Climate Experiment (GRACE) mission has been a principal contributor in the study and quantification of Earth's time-varying gravity field. Both GRACE and its successor, GRACE Follow-On, are limited by their paired satellite design which only provide a full map of Earth's gravity field approximately every thirty days and at large spatial resolutions of over 300 km. Micro-satellite technology has presented the feasibility of improving the architecture of future missions to address these issues with the implementation of a constellations of satellites having similar characteristics as GRACE. To optimize the constellation's architecture, several scenarios are evaluated to determine how implementing this configuration affects the resultant gravity field maps and characterize which instrument system errors improve, which do not, and how changes in constellation architecture affect these errors.

ECLSS and Thermal Systems Integration Challenges Across the Constellation Architecture
NASA Technical Reports Server (NTRS)
Carrasquillo, Robyn
2010-01-01
As the Constellation Program completes its initial capability Preliminary Design Review milestone for the Initial Capability phase, systems engineering of the Environmental Control and Life Support (ECLS) and Thermal Systems for the various architecture elements has progressed from the requirements to design phase. As designs have matured for the Ares, Orion, Ground Systems, and Extravehicular (EVA) System, a number of integration challenges have arisen requiring analyses and trades, resulting in changes to the design and/or requirements. This paper will address some of the key integration issues and results, including the Orion-to-Ares shared compartment venting and purging, Orion-to-EVA suit loop integration issues with the suit system, Orion-to-ISS and Orion-to-Altair intermodule ventilation, and Orion and Ground Systems impacts from post-landing environments.

The ESA Nanosatellite Beacons for Space Weather Monitoring Study
NASA Astrophysics Data System (ADS)
Hapgood, M.; Eckersley, S.; Lundin, R.; Kluge, M.
2008-09-01
This paper will present final results from this ESA-funded study that has investigated how current and emerging concepts for nanosats may be used to monitor space weather conditions and provide improved access to data needed for space weather services. The study has reviewed requirements developed in previous ESA space weather studies to establish a set of service and measurements requirements appropriate to nanosat solutions. The output is conveniently represented as a set of five distinct classes of nanosat constellations, each in different orbit locations and which can address a specific group of measurement requirements. One example driving requirement for several of the constellations was the need for real-time data reception. Given this background, the study then iterated a set of instrument and spacecraft solutions to address each of the nanosat constellations from the requirements. Indeed, iteration has proved to be a critical aspect of the study. The instrument solutions have driven a refinement of requirements through assessment of whether or not the physical parameters to be measured dictate instrument components too large for a nanosat. In addition, the study has also reviewed miniaturization trends for instruments relevant to space weather monitoring by nanosats, looking at the near, mid and far-term timescales. Within the spacecraft solutions the study reviewed key technology trends relevant to space weather monitoring by nanosats: (a) micro and nano-technology devices for spacecraft communications, navigation, propulsion and power, and (b) development and flight experience with nanosats for science and for engineering demonstration. These requirements and solutions were then subject to an iterative system and mission analysis including key mission design issues (e.g. launch/transfer, mission geometry, instrument accommodation, numbers of spacecraft, communications architectures, de-orbit, nanosat reliability and constellation robustness) and the impact of nanosat fundamental limitations (e.g. mass, volume/size, power, communications). As a result, top-level Strawman mission concepts were developed for each constellation, and ROM costs were derived for programme development, operation and maintenance over a ten-year period. Nanosat reliability and constellation robustness were shown to be a key driver in deriving mission costs. In parallel with the mission analysis the study results have been reviewed to identify key issues that determine the prospects for a space weather nanosat programme and to make recommendations on measures to enable implementation of such a programme. As a follow-on to this study, a student MSc project was initiated by Astrium at Cranfield University to analyse a potential space weather precursor demonstration mission in GTO (one of the recommendations from this ESA study), composing of a reduced constellation of nanosats, launched on ASAP or some other low cost method. The demonstration would include: 1/ Low cost multiple manufacture techniques for a fully industrial nanosat constellation programme 2/ Real time datalinks and fully operational mission for space weather 3/ Miniaturised payloads to fit in a nanosat for space weather monitoring: 4/ Other possible demonstrations of advanced technology The aim was to comply with ESA demonstration mission (i.e. PROBA-type) requirements, to be representative on issues such as cost and risk

EPA's Reanalysis of Key Issues Related to Dioxin Toxicity and ...
EPA is releasing for external peer review and public comment an important draft document reviewing the literature on the health effects of dioxin and related compounds (also referred to as 2,3,7,8-Tetrachlorodibenzo-p-dioxin). At the request of Administrator Jackson, EPA is in the process of re-assessing the science on the effects of dioxin, a toxic chemical that is emitted by multiple sources, on the public’s health. This draft dioxin report is EPA’s response to key comments and recommendations made by the National Academy of Sciences on the Agency’s draft dioxin reassessment. This assessment has been in progress for many years and raises health issues of broad interest to scientists and policymakers across the federal family. The Agency’s draft report includes significant new analyses on potential cancer and non-cancer human health effects that may result from exposures to dioxins and includes an oral reference dose for what is considered to be the most toxic of the dioxin-like compounds.

The Protocol on Strategic Environmental Assessment (SEA) to the United Nations Economic Commission for Europe (UNECE) Espoo Convention came into force on 11 July 2010. This Protocol, to which the European Union is party, gives a legal basis for enhanced attention to human health in the SEA process. In this context, the United Kingdom's (UK's) 2007 Draft Guidance on Health in Strategic Environmental Assessment represents an important early government-led effort to bring health issues and public health considerations more significantly into the SEA process. Since the UK is a worldwide leader in environmental and various other types of impact assessment,more » and since other countries may eventually consider its example in efforts to meet UNECE SEA Protocol requirements, scrutiny of its outputs is warranted. This paper thus examines the UK's Draft Guidance from both HIA academic and practitioner perspectives. First it assesses the extent to which the Draft Guidance reflects recent issues and lessons learned in the academic literature. In order to make the assessment, a meta-analysis of 70 HIA-related peer-reviewed articles was undertaken to extract authors' priority recommendations. These recommendations were subsequently compared with the contents of the Draft Guidance. Secondly, the Draft Guidance was assessed for its accordance with recommendations of the UNECE SEA Protocol background paper written by two HIA practitioners. Overall, the Draft Guidance's accordance with both sets of recommendations was found to be high, with only a few easily-remedied gaps. This evaluation suggests that the UK's Draft Guidance can be a useful starting point in the creation of future guidance on health in SEA in both the UK and other countries.« less

NANOTECHNOLOGY WHITE PAPER | Science Inventory | US ...
Nanotechnology is the science of manipulating materials at the atomic and molecular level to develop new or enhanced materials and products. In December 2004, EPA’s Science Policy Council created a cross-Agency workgroup to identify and describe the issues EPA must address to ensure protection of human health and the environment as this new technology is developed. The draft white paper on nanotechnology is the product of the workgroup. The draft white paper describes the technology, and provides a discussion of the potential environmental benefits of nanotechnology and its applications that can foster sustainable use of resources. Risk management issues and the Agency’s statutory mandates are outlined, followed by an extensive discussion of risk assessment issues. The paper identifies research needs for both environmental applications and implications of nanotechnology and concludes with recommendations on next steps for addressing science policy issues and research needs. Supplemental information is provided in a number of appendices. The Agency will use the white paper to address research needs and risk assessment issues concerning nanotechnology. The draft white paper will undergo independent expert review, which will be conducted in the February time frame. All public comments received by January 31, 2006 will be submitted to the external review panel for their consideration. Comments received beyond that time will be considered by EPA. Follo

DOE Office of Scientific and Technical Information (OSTI.GOV)
Johnson, G.J.; Rose, W.M.; Domenici, P.V.
This paper describes a unique negotiation process leading to authorization of the U.S. Department of Energy (DOE) to manage and dispose remote-handled (RH) transuranic (TRU) mixed wastes at the Waste Isolation Pilot Plant (WIPP). The negotiation process involved multiple entities and individuals brought together under authority of the New Mexico Environment Department (NMED) to discuss and resolve technical and facility operational issues flowing from an NMED-issued hazardous waste facility Draft Permit. The novel negotiation process resulted in numerous substantive changes to the Draft Permit, which were ultimately memorialised in a 'Draft Permit as Changed'. This paper discusses various aspects ofmore » the negotiation process, including events leading to the negotiations, regulatory basis for the negotiations, negotiation participants, and benefits of the process.

Yucca Mountain nuclear waste repository prompts heated congressional hearing
NASA Astrophysics Data System (ADS)
Showstack, Randy
2011-11-01
Although the final report of the Blue Ribbon Commission on America's Nuclear Future is not expected until January 2012, the tentative conclusions of the commission's draft report were dissected during a recent joint hearing by two subcommittees of the House of Representatives' Committee on Science, Space, and Technology. Among the more heated issues debated at the hearing was the fate of the stalled Yucca Mountain nuclear waste repository in Nevada. The Blue Ribbon Commission's (BRC) draft report includes recommendations for managing nuclear waste and for developing one or more permanent deep geological repositories and interim storage facilities, but the report does not address the future of Yucca Mountain. The BRC charter indicates that the commission is to "conduct a comprehensive review of policies for managing the back end of the nuclear fuel cycle." However, the draft report states that the commission was not asked to consider, and therefore did not address, several key issues. "We have not rendered an opinion on the suitability of the Yucca Mountain site or on the request to withdraw the license application for Yucca Mountain," the draft report states.

Race Margaret S. (Editor); DeVincenzi, Donald L. (Editor); Rummel, John D. (Editor); Acevedo, Sara E. (Editor)
2001-01-01
In preparation for missions to Mars that will involve the return of samples to Earth, it will be necessary to prepare for the receiving, handling, testing, distributing, and archiving of martian materials here on Earth. Previous groups and committees have studied selected aspects of sample return activities, but specific detailed protocols for the handling and testing of returned samples must still be developed. To further refine the requirements for sample hazard testing and to develop the criteria for subsequent release of sample materials from quarantine, the NASA Planetary Protection Officer convened a series of workshops in 2000-2001. The overall objective of the Workshop Series was to produce a Draft Protocol by which returned martian sample materials can be assessed for biological hazards and examined for evidence of life (extant or extinct) while safeguarding the purity of the samples from possible terrestrial contamination. This report also provides a record of the proceedings of Workshop 4, the final Workshop of the Series, which was held in Arlington, Virginia, June 5-7, 2001. During Workshop 4, the sub-groups were provided with a draft of the protocol compiled in May 2001 from the work done at prior Workshops in the Series. Then eight sub-groups were formed to discuss the following assigned topics: Review and Assess the Draft Protocol for Physical/Chemical Testing Review and Assess the Draft Protocol for Life Detection Testing Review and Assess the Draft Protocol for Biohazard Testing Environmental and Health/Monitoring and Safety Issues Requirements of the Draft Protocol for Facilities and Equipment Contingency Planning for Different Outcomes of the Draft Protocol Personnel Management Considerations in Implementation of the Draft Protocol Draft Protocol Implementation Process and Update Concepts This report provides the first complete presentation of the Draft Protocol for Mars Sample Handling to meet planetary protection needs. This Draft Protocol, which was compiled from deliberations and recommendations from earlier Workshops in the Series, represents a consensus that emerged from the discussions of all the sub-groups assembled over the course of the five Workshops of the Series. These discussions converged on a conceptual approach to sample handling, as well as on specific analytical requirements. Discussions also identified important issues requiring attention, as well as research and development needed for protocol implementation.

Simulating 3D Spacecraft Constellations for Low Frequency Radio Imaging
NASA Astrophysics Data System (ADS)
Hegedus, A. M.; Amiri, N.; Lazio, J.; Belov, K.; Kasper, J. C.
2016-12-01
Constellations of small spacecraft could be used to realize a low-frequency phased array for either heliophysics or astrophysics observations. However, there are issues that arise with an orbiting array that do not occur on the ground, thus rendering much of the existing radio astronomy software inadequate for data analysis and simulation. In this work we address these issues and consider the performance of two constellation concepts. The first is a 32-spacecraft constellation for astrophysical observations, and the second is a 5-element concept for pointing to the location of radio emission from coronal mass ejections (CMEs). For the first, we fill the software gap by extending the APSYNSIM software to simulate the aperture synthesis for a radio interferometer in orbit. This involves using the dynamic baselines from the relative motion of the individual spacecraft as well as the capability to add galactic noise. The ability to simulate phase errors corresponding to positional uncertainty of the antennas was also added. The upgraded software was then used to model the imaging of a 32 spacecraft constellation that would orbit the moon to image radio galaxies like Cygnus A at .3-30 MHz. Animated images showing the improvement of the dirty image as the orbits progressed were made. RMSE plots that show how well the dirty image matches the input image as a function of integration time were made. For the second concept we performed radio interferometric simulations of the Sun Radio Interferometer Space Experiment (SunRISE) using the Common Astronomy Software Applications (CASA) package. SunRISE is a five spacecraft phased array that would orbit Earth to localize the low frequency radio emission from CMEs. This involved simulating the array in CASA, creating truth images for the CMEs over the entire frequency band of SunRISE, and observing them with the simulated array to see how well it could localize the true position of the CME. The results of our analysis show that we can localize the radio emission originating from the head or flanks of the CMEs in spite of the phase errors introduced by uncertainties in orbit and clock estimation.

Three Generations of Tracking and Data Relay Satellite (TDRS) Spacecraft
NASA Technical Reports Server (NTRS)
Zaleski, Ron
2016-01-01
The current Tracking and Data Relay Satellite configuration consists of nine in-orbit satellites (four first generation, three second generation and two third generation satellites) globally distributed in geosynchronous orbit to provide near continuous data relay service to missions like Hubble Space Telescope and the International Space Station. The 1st generation spacecraft were designed by TRW/Northrop Grumman with their launches of the five spacecraft ranging from 1983 through 1995. The 2nd and 3rd generation spacecraft were designed by Boeing with their launches ranging 2000 - 2002 and 2013 - 2017 respectively. TDRS-3 is now 27 years on orbit, continues to be a capable asset for the TDRS constellation. Lack of need for inclination control combined with large fuel reserves and redundancy on critical elements provides spacecraft that operate well past design life, all of which contributes to expanded TDRS constellation support capabilities. All spacecraft generations have issues. Significant issues will be summarized with the focus on the Boeing related problems. Degradations and failures are continually assessed and provide the foundation for yearly updates to spacecraft reliability models, constellation service projections and deorbit plans (in order to meet NASAs mandate of limiting orbital debris). Even when accounting for degradations and failures, the life expectancy for the Boeing delivered 2nd generation TDRS-8, 9 10 TDRS are anticipated to be 25+ years.

External combustor for gas turbine engine
Santanam, Chandran B.; Thomas, William H.; DeJulio, Emil R.
1991-01-01
An external combustor for a gas turbine engine has a cyclonic combustion chamber into which combustible gas with entrained solids is introduced through an inlet port in a primary spiral swirl. A metal draft sleeve for conducting a hot gas discharge stream from the cyclonic combustion chamber is mounted on a circular end wall of the latter adjacent the combustible gas inlet. The draft sleeve is mounted concentrically in a cylindrical passage and cooperates with the passage in defining an annulus around the draft sleeve which is open to the cyclonic combustion chamber and which is connected to a source of secondary air. Secondary air issues from the annulus into the cyclonic combustion chamber at a velocity of three to five times the velocity of the combustible gas at the inlet port. The secondary air defines a hollow cylindrical extension of the draft sleeve and persists in the cyclonic combustion chamber a distance of about three to five times the diameter of the draft sleeve. The hollow cylindrical extension shields the drive sleeve from the inlet port to prevent discharge of combustible gas through the draft sleeve.

[Common law, civil law: thinking about the tools of the judge in bioethics].
Baudouin, Jean-Louis
2006-01-01
Civilian and common law judges differ substantially in their approach to the resolution of issues concerning bioethics and health sciences. Whereas the civilian judge will first take into account the legislative source, his common law counterpart will most probably first look at judicial precedents for guidance. In both systems, however, the legislative drafting technique differs substantially and has a direct impact on judicial interpretation of the law. Both systems also differ in the way that judicial decisions are drafted and rendered. In the common law tradition, judges draft their own opinion, leaving the possibility of dissent which, in turn, helps to better illustrate contentious issues and may have an influence on social awareness of difficult problems. Finally, in bioethics, legislation should be preferred if only for a question of social legitimacy, since decisions are then taken by elected representatives. However, this type of legislation should be subject to periodical review to better adapt its rules to the evolution of science and society.

Review of the Draft 2014 Science Mission Directorate Science Plan
NASA Technical Reports Server (NTRS)
2013-01-01
At the request of NASA's Science Mission Directorate (SMD), the National Research Council's (NRC's) Space Studies Board (SSB) initiated a study to review a draft of the SMD's 2014 Science Plan. The request for this review was made at a time when NASA is engaged in the final stages of a comprehensive, agency-wide effort to develop a new strategic plan and at a time when NASA's budget is under considerable stress. SMD's Science Plan serves to provide more detail on its four traditional science disciplines-astronomy and astrophysics, solar and space physics (also called heliophysics), planetary science, and Earth remote sensing and related activities-than is possible in the agency-wide Strategic Plan. In conducting its review of the draft Science Plan, the Committee on the Assessment of the NASA Science Mission Directorate 2014 Science Plan was charged to comment on the following specific areas: (1) Responsiveness to the NRC's guidance on key science issues and opportunities in recent NRC reports; (2) Attention to interdisciplinary aspects and overall scientific balance; (3) Identification and exposition of important opportunities for partnerships as well as education and public outreach; (4) Integration of technology development with the science program; (5) Clarity on how the plan aligns with SMD's strategic planning process; (6) General readability and clarity of presentation; and (7) Other relevant issues as determined by the committee. The main body of the report provides detailed findings and recommendations relating to the draft Science Plan. The highest-level, crosscutting issues are summarized here, and more detail is available in the main body of the report.

Making the built environment accessible for all regardless of functional capacity is an important goal for public health efforts. Considerable impediments to achieving this goal suggest the need for valid measurements of acccessibility and for greater attention to the complexity of person-environment fit issues. To address these needs, this study aimed to provide a methodological platform, useful for further research and instrument development within accessibility research. This was accomplished by the construction of a typology of problematic person-environment fit constellations, utilizing an existing methodology developed to assess and analyze accessibility problems in the built environment. By means of qualitative review and statistical methods we classified the person-environment fit components covered by an existing application which targets housing accessibility: the Housing Enabler (HE) instrument. The International Classification of Functioning, Disability and Health (ICF) was used as a conceptual framework. Qualitative classification principles were based on conceptual similarities and for quantitative analysis of similarities, Principal Component Analysis was carried out. We present a typology of problematic person-environment fit constellations classified along three dimensions: 1) accessibility problem range and severity 2) aspects of functioning 3) environmental context. As a result of the classification of the HE components, 48 typical person-environment fit constellations were recognised. The main contribution of this study is the proposed typology of person-environment fit constellations. The typology provides a methodological platform for the identification and quantification of problematic person-environment fit constellations. Its link to the globally accepted ICF classification system facilitates communication within the scientific and health care practice communities. The typology also highlights how relations between aspects of functioning and physical environmental barriers generate typical accessibility problems, and thereby furnishes a reference point for research oriented to how the built environment may be designed to be supportive for activity, participation and health.

The New US Preventive Services Task Force "C" Draft Recommendation for Prostate Cancer Screening.
Cooperberg, Matthew R
2017-09-01
The US Preventive Services Task Force has issued a new draft guideline, with a "C" recommendation that men aged 55-69 yr should be informed about the benefits and harms of screening for prostate cancer, and offered prostate-specific antigen testing if they choose it. For men aged ≥70 yr, the recommendation remains "D", or "do not screen." This draft represents substantial progress in the right direction towards offering men a fair opportunity to discuss the risks and benefits of screening with their primary care providers. However, the evidence review underlying the draft remains fundamentally inadequate, leading to biased presentations of both benefits and harms of screening. The final guideline and future revisions should reflect formal engagement with subject matter experts to optimize the advise given to men and their physicians.

This paper presents and analyses, in terms of privacy and confidentiality, the Turkish Draft Law on National DNA Database prepared in 2004, and concerning the use of DNA analysis for forensic objectives and identity verification in Turkey. After a short introduction including related concepts, we evaluate the draft law and provide articles about confidentiality. The evaluation reminded us of some important topics at international level for the developing countries. As a result, the need for sophisticated legislations about DNA databases, for solutions to issues related to the education of employees, and the technological dependency to other countries emerged as main challenges in terms of confidentiality for the developing countries. As seen in the Turkish Draft Law on National DNA Database, the protection of the fundamental rights and freedoms requires more care during the legislative efforts.

Waste Collector System Technology Comparisons for Constellation Applications
NASA Technical Reports Server (NTRS)
Broyan, James Lee, Jr.
2006-01-01
The Waste Collection Systems (WCS) for space vehicles have utilized a variety of hardware for collecting human metabolic wastes. It has typically required multiple missions to resolve crew usability and hardware performance issues that are difficult to duplicate on the ground. New space vehicles should leverage off past WCS systems. Past WCS hardware designs are substantially different and unique for each vehicle. However, each WCS can be analyzed and compared as a subset of technologies which encompass fecal collection, urine collection, air systems, pretreatment systems. Technology components from the WCS of various vehicles can then be combined to reduce hardware mass and volume while maximizing use of previous technology and proven human-equipment interfaces. Analysis of past US and Russian WCS are compared and extrapolated to Constellation missions.

The Federal Constitution of 1988 allowed the National Congress to contribute towards formulation of new public policies. The objective of this study was to analyze the legislative production that dealt with health issues that was in passage in the National Congress between January 2007 and December 2008. Descriptive-exploratory cross-sectional study with quantitative and qualitative approaches, conducted in a federal university. The analysis material for the study comprised 144 draft bills that were classified and subsequently randomly evaluated by 155 professionals working within the healthcare system. The analysis showed that the Workers' Party (PT) and Brazilian Democratic Movement Party (PMDB) were the parties that presented the largest proportions of the draft bills (12.5% and 11.1%); 25.4% of the draft bills were presented by congress members with academic qualifications within healthcare and only 1.4% of the draft bills became transformed into legal regulations. In questionnaire responses, 51.5% of the evaluators did not consider the draft bills to be viable, 40.6% did not consider them to be relevant and 52.5% said that if the draft bills were not approved it would not be harmful to Brazilian society. In analyzing the data from this study, it was noted that the legislative production relating to healthcare was low and the transformation rate from draft bill to legal regulation was negligible. The results from the evaluation showed that the quality of legislative production was impaired.

Biomass as a fuel for cooking is a common practice in rural India, and about 700 million people use traditional stoves to meet their energy demand. However, the thermal and the combustion efficiencies of these stoves are very low, leading to an inefficient use of biomass, and also, resulting in significant indoor air pollution. Research development has however led to the development of some improved stoves viz., natural draft and forced draft for both domestic as well as large scale cooking applications and government is trying to promote them. Forced draft stoves using processed biomass fuels (pellets) have received more prominence due to their superior performance, however, higher initial cost and limited fuel distribution networks have remained the key challenges. Improved natural draft stoves too have gained attention for being relatively inexpensive, and they are more likely to hit the rural households. In this paper, we have examined the environmental benefits obtained by the use of improved stoves for two important scenarios: traditional stoves are replaced by (i)improved natural draft stoves and, (ii) by improved natural draft as well as forced draft stoves. In the best case scenario (case ii), i.e., by shifting 111 million households who currently use wood to the forced draft stoves, and another 45 million households who are dependent on dung cake and agro residues to the improved natural draft stoves, the emission reduction that can be achieved are as follows: particulate matter (PM) 875 kT, black carbon (BC) 229 kT, organic carbon (OC) 525 kT, methane (CH 4 )1178 kT and non methane hydrocarbon (NMHC) of 564 kT. With the promotion of only natural draft improved stoves, the total reductions would be ∼12% lower than the combinational promotion. The CO 2 equivalent reduction is estimated to be ∼70-80 MT per year. Copyright © 2017 Elsevier Ltd. All rights reserved.

In Brief: Geoengineering draft statement
NASA Astrophysics Data System (ADS)
Showstack, Randy
2009-04-01
The American Meteorological Society (AMS) has prepared a draft policy statement on geoengineering the climate system, which the AMS Council is considering for approval. The statement notes, “Geoengineering will not substitute for either aggressive mitigation or proactive adaptation. It could contribute to a comprehensive risk management strategy to slow climate change and alleviate its negative impacts, but the potential for adverse and unintended consequences implies a need for adequate research, appropriate regulation, and transparent consideration.” The statement, if adopted, indicates that AMS recommends enhanced research on the scientific and technological potential for geoengineering the climate system; additional study of the historical, ethical, legal, political, and societal aspects of the geoengineering issues; and the development and analysis of policy options to promote transparency and international cooperation in exploring geoengineering options along with restrictions on reckless efforts to manipulate the climate system. AMS is accepting comments on the draft statement until 23 April. For more information, visit http://ametsoc.org/policy/draftstatements/index.html#draft.

Current studies indicate that there are stable orbits around but far away from the triangular libration points .Two special quasi-periodic orbits around each triangular libration points L4 , L5 in the Earth-Moon sys-tem perturbed by Sun are gain , and the stable orbits discussed in this work are ideal places for space colonies because no orbit control is needed. These stable orbits can also be used as nominal orbits for space VLBI (Very Long Baseline Interferometry) stations. The two stations can also form baselines with stations on the Earth and the Moon, or with stations located around another TLP. Due to the long distance between the stations, the observation precision can be greatly enhanced compared with the VLBI stations on the Earth. Such a VLBI constellation not only can advance the radio astronomy, but also can be used as a navigation system for human activities in the Earth-Moon system and even in the solar system. This paper will focus on the navigation constellation coverage issues, and the orbit determination accuracy problems within the Earth-Moon sys-tem and interplanetary space.

BRIght Target Explorer (BRITE) Constellation, the first nanosatellite mission applied to astrophysical research, is a collaboration among Austria, Canada and Poland. The fleet of satellites (6 launched; 5 functioning) performs precise optical photometry of the brightest stars in the night sky. A pioneering mission like BRITE—with optics and instruments restricted to small volume, mass and power in several nanosatellites, whose measurements must be coordinated in orbit—poses many unique challenges. We discuss the technical issues, including problems encountered during on-orbit commissioning (especially higher-than-expected sensitivity of the CCDs to particle radiation). We describe in detail how the BRITE team has mitigated these problems, and provide a complete overview of mission operations. This paper serves as a template for how to effectively plan, build and operate future low-cost niche-driven space astronomy missions. Based on data collected by the BRITE Constellation satellite mission, designed, built, launched, operated and supported by the Austrian Research Promotion Agency (FFG), the University of Vienna, the Technical University of Graz, the Canadian Space Agency (CSA), the University of Toronto Institute for Aerospace Studies (UTIAS), the Foundation for Polish Science & Technology (FNiTP MNiSW), and National Science Centre (NCN).

Bastida Virgili, Benjamin; Krag, Holger
2016-07-01
Space traffic has always been subject to considerable fluctuations. In the past, these fluctuations have been mainly driven by geopolitical and economic factors. During the last years there has been a considerable increase due to the use of cubesats by non-traditional space operators, and due to a significant change of mission scopes and mission orbits in Low Earth Orbit (LEO). In the near future, however, many indications point to a further increase in the space traffic in LEO. This increase is mainly driven by a cheaper access to space, also triggered by the miniaturisation of spacecraft systems. An acceleration of this trend is expressed by the announcement of large constellations in LEO with the purpose to provide broadband internet communication, allowing to minimise the required infrastructure on Earth. The number of artificial objects in orbit continues to increase and, with it, a key threat to space sustainability. In response, space agencies have identified a set of mitigation guidelines aimed at enabling space users to reduce the generation of space debris by, for example, limiting the orbital lifetime of their spacecraft and of launcher stages after the end of their mission to 25 years in LEO. However, several recent studies have shown that, today, current guidelines for the LEO protected zone are insufficiently applied by space systems of all sizes. Under these conditions, a step increase in the launch rate is a potential concern for the environment, in particular if the current End of Life (EOL) behaviour prevails in the future. Even in a perfect behaviour w.r.t. the 25 year lifetime rule, the new traffic might lead to unrecoverable environment trends. Furthermore, the requirement for reliability of the disposal function is of 90%, however, weighted with the reliability of the entire system. A failure rate of 10%, in general, was found to be acceptable under current space traffic conditions. This might not be sustainable when the LEO launch rates increase drastically. In this study, we report the detected issues of such a mega-constellation traffic, and we analyse the response of the space object population to the introduction of a large constellation conforming to the post-mission disposal guideline with differing levels of success and with different disposal orbit options.

New Issues for New Methods: Ethical and Editorial Challenges for an Experimental Philosophy.
Polonioli, Andrea
2017-08-01
This paper examines a constellation of ethical and editorial issues that have arisen since philosophers started to conduct, submit and publish empirical research. These issues encompass concerns over responsible authorship, fair treatment of human subjects, ethicality of experimental procedures, availability of data, unselective reporting and publishability of research findings. This study aims to assess whether the philosophical community has as yet successfully addressed such issues. To do so, the instructions for authors, submission process and published research papers of 29 main journals in philosophy have been considered and analyzed. In light of the evidence reported here, it is argued that the philosophical community has as yet failed to properly tackle such issues. The paper also delivers some recommendations for authors, reviewers and editors in the field.

Perverse dreams and dreams of perversion.
Good, Michael I
2006-10-01
This paper (1) posits the occurrence of perverse dreams as a type of mental phenomenon in the constellation of perverse processes; (2) considers manifest dreams of frank perversion as a type of perverse dream within the class of perverse dreams as a whole; (3) relates the subtype of perverse dreams without manifest perversions to the occurrence of perverse defenses and the development of a perverse transference; and (4) suggests that consideration to perverse dreams in the psychoanalytic process finds application in identifying and differentiating perverse defenses from neurotic and other characterologic patterns; in identifying and tracing the vicissitudes of difficult perverse transference-countertransference constellations; and in furthering perverse patients' recognition and understanding of particularly troublesome and seemingly intractable issues in their psychic makeup. Clinical material illustrates perverse dreams and their usefulness in the often arduous process of analyzing perverse defenses.

Design Methodology and Method and Apparatus for Signaling with Capacity Optimized Constellation Abstract Communication systems are described that use geometrically PSK shaped constellations that have increased capacity compared to conventional PSK constellations operating within a similar SNR band. The geometrically shaped PSK constellation is optimized based upon parallel decoding capacity. In many embodiments, a capacity optimized geometrically shaped constellation can be used to replace a conventional constellation as part of a firmware upgrade to transmitters and receivers within a communication system. In a number of embodiments, the geometrically shaped constellation is optimized for an Additive White Gaussian Noise channel or a fading channel. In numerous embodiments, the communication uses adaptive rate encoding and the location of points within the geometrically shaped constellation changes as the code rate changes.

The renewed emphasis on robotic and human missions within NASA's space exploration program warrants a detailed consideration of how the positions of objects in space will be determined and tracked, whether they be spacecraft, human explorers, robots, surface vehicles, or science instrumentation. The Navigation Team within the NASA Space Communications Architecture Working Group (SCAWG) has addressed several key technical issues in this area and the principle findings are reported here. For navigation in the vicinity of the Moon, a variety of satellite constellations have been investigated that provide global or regional surface position determination and timely services analogous to those offered by GPS at Earth. In the vicinity of Mars, there are options for satellite constellations not available at the Moon due to the gravitational perturbations from Earth, such as two satellites in an aerostationary orbit. Alternate methods of radiometric navigation as considered, including one- and two-way signals, as well as autonomous navigation. The use of a software radio capable of receiving all available signal sources, such as GPS, pseudolites, and communication channels, is discussed. Methods of time transfer and dissemination are also considered in this paper.

1997-01-01
Much attention in recent years has focused on commercial telecommunications ventures involving constellations of spacecraft in low and medium Earth orbit. These projects often require investments on the order of billions of dollars (US$) for development and operations, but surprisingly little work has been published on constellation design optimization for coverage analysis, traffic simulation and launch sequencing for constellation build-up strategies. This paper addresses the two most critical aspects of constellation orbital design — efficient constellation candidate generation and coverage analysis. Inefficiencies and flaws in the current standard algorithm for constellation modeling are identified, and a corrected and improved algorithm is presented. In the 1970's, John Walker and G. V. Mozhaev developed innovative strategies for continuous global coverage using symmetric non-geosynchronous constellations. (These are sometimes referred to as rosette, or Walker constellations. An example is pictured above.) In 1980, the late Arthur Ballard extended and generalized the work of Walker into a detailed algorithm for the NAVSTAR/GPS program, which deployed a 24 satellite symmetric constellation. Ballard's important contribution was published in his "Rosette Constellations of Earth Satellites."

The Earth Science Afternoon Constellation: Preparing for Autonomous but Coordinated Operations
NASA Technical Reports Server (NTRS)
Case, Warren; Kelly, Angelita C.; Work, Kevin; Guit, William
2005-01-01
This paper describes how the challenges of coordinating the autonomous operations of geographically dispersed mission control centers for several small and large satellites are being overcome. The Earth Science Afternoon Constellation, also referred to as the "A-Train", is an international grouping of five NASA satellites (two major NASA EOS missions and three NASA/Earth System Science Pathfinder missions) and one French satellite orbiting in close proximity. This grouping of satellites provides scientists with the opportunity to perform coincident observations using data from two or more instruments on various satellites with measurements taken at approximately the same time. Three of the six missions are currently on-orbit, with the two missions expected to join the constellation later this year and one mission in 2007. The operational challenges are daunting for several reasons. There are several Mission Control Centers (widely separated on two continents), operating autonomously under tight budget constraints. All of the Mission Control Centers have reasons to be concerned about safety while flying in close proximity to other satellites, but most Centers did not have the resources or the desire to address this concern alone - the interfaces are too numerous and anticipated operations too costly. Clearly, an efficient approach was needed. This paper describes the steps taken to make this Earth science constellation a reality. Agreements were forged to allow the Mission Control Centers to maintain their autonomy, while ensuring their satellite's safety. Each member mission in the constellation operates independently in accordance with its own mission requirements, but the member missions have agreed to coordinate their operations, i.e., orbital positions and control to ensure the safety of the entire constellation. A centralized system was developed at NASA Goddard Space Flight Center to collect, analyze, and distribute ephemeris data used by each of the mission teams to determine the positions of the satellites in the constellation. The system issues warnings regarding possible dangerous configurations, eliminating the need for redundant capabilities at each Mission Control Center. On-orbit contingency situations were identified and analyzed; agreements were reached in advance of contingency operations to ensure that coordination between the Mission Control Centers can be handled expeditiously and fairly. In this manner, recovery from anomalous situations can be more quickly realized, thereby increasing the science return and reducing costs. The process used to develop these contingency procedures and the systems used to facilitate the contingency resolution are described as well.

Communication systems are described that use signal constellations, which have unequally spaced (i.e., `geometrically` shaped) points. In many embodiments, the communication systems use specific geometric constellations that are capacity optimized at a specific SNR (signal to noise ratio). In addition, ranges within which the constellation points of a capacity optimized constellation can be perturbed and are still likely to achieve a given percentage of the optimal capacity increase compared to a constellation that maximizes d (sub min) (i.e. minimum distance between constellations) are also described. Capacity measures that are used in the selection of the location of constellation points include, but are not limited to, parallel decode (PD) capacity and joint capacity.

Constellation Coverage Analysis
NASA Technical Reports Server (NTRS)
Lo, Martin W. (Compiler)
1997-01-01
The design of satellite constellations requires an understanding of the dynamic global coverage provided by the constellations. Even for a small constellation with a simple circular orbit propagator, the combinatorial nature of the analysis frequently renders the problem intractable. Particularly for the initial design phase where the orbital parameters are still fluid and undetermined, the coverage information is crucial to evaluate the performance of the constellation design. We have developed a fast and simple algorithm for determining the global constellation coverage dynamically using image processing techniques. This approach provides a fast, powerful and simple method for the analysis of global constellation coverage.

Classified and clustered data constellation: An efficient approach of 3D urban data management
NASA Astrophysics Data System (ADS)
Azri, Suhaibah; Ujang, Uznir; Castro, Francesc Antón; Rahman, Alias Abdul; Mioc, Darka
2016-03-01
The growth of urban areas has resulted in massive urban datasets and difficulties handling and managing issues related to urban areas. Huge and massive datasets can degrade data retrieval and information analysis performance. In addition, the urban environment is very difficult to manage because it involves various types of data, such as multiple types of zoning themes in the case of urban mixed-use development. Thus, a special technique for efficient handling and management of urban data is necessary. This paper proposes a structure called Classified and Clustered Data Constellation (CCDC) for urban data management. CCDC operates on the basis of two filters: classification and clustering. To boost up the performance of information retrieval, CCDC offers a minimal percentage of overlap among nodes and coverage area to avoid repetitive data entry and multipath query. The results of tests conducted on several urban mixed-use development datasets using CCDC verify that it efficiently retrieves their semantic and spatial information. Further, comparisons conducted between CCDC and existing clustering and data constellation techniques, from the aspect of preservation of minimal overlap and coverage, confirm that the proposed structure is capable of preserving the minimum overlap and coverage area among nodes. Our overall results indicate that CCDC is efficient in handling and managing urban data, especially urban mixed-use development applications.

Corporations now included under Section 189
DOE Office of Scientific and Technical Information (OSTI.GOV)
Arlinghaus, B.P.; Anderson, D.T.
1983-12-01
This article examines some of the issues, including the ''real property'' question, that corporations may encounter in implementing the provisions of Code Section 189 and its regulations. The extension of 189 to regular corporations represents a significant change in congressional intent, since it was originally enacted as a reform measure and is now primarily a provision to raise revenue at a time when Congress is facing a large dificit. Code Section 189 was conceived and enacted in haste, however, and this expansion will undoubtedly have an adverse impact on capital investment at a time when stimulation is needed for themore » economy as a whole. The workload of the courts and the Internal Revenue Service will certainly increase. Careful drafting of the regulations could anticipate potential issues and clarify them in the drafting stage. The meaning of real property, capitalization rate, capitalization period, and self-constructed assets all need to be carefully addressed. 18 references.« less

In November 2007, the Draft Programmatic Environmental Impact Statement on Designation of Energy Corridors on Federal Land in the Western 11 States was released. The draft proposes a network of 6055 miles of energy corridors on lands managed by seven different federal agencies. Determining the proposed locations of the corridors was a large collaborative effort among the agencies and included local, state, and federal land managers. To connect this geographically dispersed group of people, the project team employed a variety of approaches to communicate corridor siting issues, including sharing GIS layers and electronic maps, a downloadable GIS database and ArcReadermore » project, workshops, and Internet webcast teleconferences. This collaborative approach allowed difficult siting issues to be understood and discussed from many perspectives, which resulted in rapid and effective decision making. The result was a proposed corridor system that avoids many sensitive resources and protected lands while accommodating expected energy development.« less

As development of the Constellation Space Suit Element progresses, designing the most effective and efficient life support systems is critical. The baseline schematic analysis for the Portable Life Support System (PLSS) indicates that the ventilation loop will need some method of heat exchange and humidification prior to entering the helmet. A trade study was initiated to identify the challenges associated with conditioning the spacesuit breathing gas stream for temperature and water vapor control, to survey technological literature and resources on heat exchanger and humidifiers to provide solutions to the problems of conditioning the spacesuit breathing gas stream, and to propose potential candidate technologies to perform the heat exchanger and humidifier functions. This paper summarizes the results of this trade study and also describes the conceptual designs that NASA developed to address these issues.

Apollo Video Photogrammetry Estimation of Plume Impingement Effects
NASA Technical Reports Server (NTRS)
Immer, Christopher; Lane, John; Metzger, Philip; Clements, Sandra
2008-01-01
Each of the six Apollo mission landers touched down at unique sites on the lunar surface. Aside from the Apollo 12 landing site located 180 meters from the Surveyor III lander, plume impingement effects on ground hardware during the landings were largely not an issue. The Constellation Project's planned return to the moon requires numerous landings at the same site. Since the top few centimeters are loosely packed regolith, plume impingement from the lander ejects the granular material at high velocities. With high vacuum conditions on the moon (10 (exp -14) to 10 (epx -12) torr), motion of all particles is completely ballistic. Estimates from damage to the Surveyor III show that the ejected regolith particles to be anywhere 400 m/s to 2500 m/s. It is imperative to understand the physics of plume impingement to safely design landing sites for the Constellation Program.

Constellations: A New Paradigm for Earth Observations
NASA Technical Reports Server (NTRS)
Kelly, Angelita C.; Volz, Stephen M.; Yuhas, Cheryl L.; Case, Warren F.
2009-01-01
The last decade has seen a significant increase in the number and the capabilities of remote sensing satellites launched by the international community. A relatively new approach has been the launching of satellites into heterogeneous constellations. Constellations provide the scientists a capability to acquire science data, not only from specific instruments on a single satellite, but also from instruments on other satellites that fly in the same orbit. Initial results from the A-Train (especially following the CALIPSO/CloudSat launch) attest to the tremendous scientific value of constellation flying. This paper provides a history of the constellations (particularly the A-Train) and how the A-Train mission design was driven by science requirements. The A-Train has presented operational challenges which had not previously been encountered. Operations planning had to address not only how the satellites of each constellation operate safely together, but also how the two constellations fly in the same orbits without interfering with each other when commands are uplinked or data are downlinked to their respective ground stations. This paper discusses the benefits of joining an on-orbit constellation. When compared to a single, large satellite, a constellation infrastructure offers more than just the opportunities for coincidental science observations. For example, constellations reduce risks by distributing observing instruments among numerous satellites; in contrast, a failed launch or a system failure in a single satellite would lead to loss of all observations. Constellations allow for more focused, less complex satellites. Constellations distribute the development, testing, and operations costs among various agencies and organizations for example, the Morning and Afternoon Constellations involve several agencies within the U.S. and in other countries. Lastly, this paper addresses the need to plan for the long-term evolution of a constellation. Agencies need to have a replenishment strategy as some satellites age and eventually leave the constellation. This will ensure overlap of observations, thus providing continuous, calibrated science data over a much longer time period. Thoughts on the evolution of the A-Train will also be presented.

Capacity Maximizing Constellations
NASA Technical Reports Server (NTRS)
Barsoum, Maged; Jones, Christopher
2010-01-01
Some non-traditional signal constellations have been proposed for transmission of data over the Additive White Gaussian Noise (AWGN) channel using such channel-capacity-approaching codes as low-density parity-check (LDPC) or turbo codes. Computational simulations have shown performance gains of more than 1 dB over traditional constellations. These gains could be translated to bandwidth- efficient communications, variously, over longer distances, using less power, or using smaller antennas. The proposed constellations have been used in a bit-interleaved coded modulation system employing state-ofthe-art LDPC codes. In computational simulations, these constellations were shown to afford performance gains over traditional constellations as predicted by the gap between the parallel decoding capacity of the constellations and the Gaussian capacity

2012-01-01
A promising area of small satellite development is in providing higher temporal resolution than larger satellites. Traditional constellations have required specific orbits and dedicated launch vehicles. In this paper we discuss an alternative architecture in which the individual elements of the constellation are launched as rideshare opportunities. We compare the coverage of such an ad-hoc constellation with more traditional constellations. Coverage analysis is based on actual historical data from rideshare opportunities. Our analysis includes ground coverage and temporal revisits for Polar, Tropics, Temperate, and Global regions, comparing ad-hoc and Walker constellation.

One of the advantages that drive nanosatellite development is the potential of multi-point observation through constellation operation. However, constellation deployment of nanosatellites has been a challenge, as thruster operations for orbit maneuver were limited due to mass, volume, and power. Recently, a de-orbiting mechanism using magnetic torquer interaction with space plasma has been introduced, so-called plasma drag. As no additional hardware nor propellant is required, plasma drag has the potential in being used as constellation deployment method. In this research, a novel constellation deployment method using plasma drag is proposed. Orbit decay rate of the satellites in a constellation is controlled using plasma drag in order to achieve a desired phase angle and phase angle rate. A simplified 1D problem is formulated for an elementary analysis of the constellation deployment time. Numerical simulations are further performed for analytical analysis assessment and sensitivity analysis. Analytical analysis and numerical simulation results both agree that the constellation deployment time is proportional to the inverse square root of magnetic moment, the square root of desired phase angle and the square root of satellite mass. CubeSats ranging from 1 to 3 U (1-3 kg nanosatellites) are examined in order to investigate the feasibility of plasma drag constellation on nanosatellite systems. The feasibility analysis results show that plasma drag constellation is feasible on CubeSats, which open up the possibility of CubeSat constellation missions.

The 2-D lattice theory of Flower Constellations
NASA Astrophysics Data System (ADS)
Avendaño, Martín E.; Davis, Jeremy J.; Mortari, Daniele
2013-08-01
The 2-D lattice theory of Flower Constellations, generalizing Harmonic Flower Constellations (the symmetric subset of Flower Constellations) as well as the Walker/ Mozhaev constellations, is presented here. This theory is a new general framework to design symmetric constellations using a 2× 2 lattice matrix of integers or by its minimal representation, the Hermite normal form. From a geometrical point of view, the phasing of satellites is represented by a regular pattern (lattice) on a two-Dimensional torus. The 2-D lattice theory of Flower Constellations does not require any compatibility condition and uses a minimum set of integer parameters whose meaning are explored throughout the paper. This general minimum-parametrization framework allows us to obtain all symmetric distribution of satellites. Due to the J_2 effect this design framework is meant for circular orbits and for elliptical orbits at critical inclination, or to design elliptical constellations for the unperturbed Keplerian case.

Communication systems are described that use geometrically shaped constellations that have increased capacity compared to conventional constellations operating within a similar SNR band. In several embodiments, the geometrically shaped is optimized based upon a capacity measure such as parallel decoding capacity or joint capacity. In many embodiments, a capacity optimized geometrically shaped constellation can be used to replace a conventional constellation as part of a firmware upgrade to transmitters and receivers within a communication system. In a number of embodiments, the geometrically shaped constellation is optimized for an Additive White Gaussian Noise channel or a fading channel. In numerous embodiments, the communication uses adaptive rate encoding and the location of points within the geometrically shaped constellation changes as the code rate changes.

Environmental problems that cross national borders are attracting increasing public and political attention; regulating them involves coordinating the goals and activities of various governments, which often presupposes simplifying and standardizing complex knowledge, and finding ways to manage uncertainty. This article explores how transboundary environmental problems are dealt with to render complex issues governable. By discussing oil pollution in the Baltic Sea and the gas pipeline between Russia and Germany, we elucidate how boundaries are negotiated to make issues governable. Three processes are found to be particularly relevant to how involved actors render complex issues governable: complexity reduction, construction of a spatial identity for an issue, and ascription of capabilities to new or old actor constellations. We conclude that such regulation is always provisional, implying that existing regulation is always open for negotiation and criticism.

An Investigation into Establishing a Formation of Small Satellites in a Lunar Flower Constellation
NASA Astrophysics Data System (ADS)
McManus, Lauren
Lunar science missions such as LADEE and GRAIL achieved unprecedented measurements of the Lunar exosphere and gravity field. These missions were performed with one (LADEE) or two (GRAIL) traditional satellites. The global coverage achieved by these missions could have been greatly enhanced with the use of a constellation of satellites. A constellation of communication satellites at the Moon would also be necessary if a Lunar human base were to be established. Constellations with many satellites are expensive with traditional technology, but have become feasible through the technological advancements and affordability of cubesats. Cubesat constellations allow for full surface coverage in science or communication missions at a reasonable mission cost. Repeat ground track orbits offer interesting options for science or communication constellations, since they provide repeat coverage of the surface at a fixed time between sequential visits. Flower constellations are a family of constellations being studied primarily by Daniele Mortari at Texas A&M; University that make use of repeat ground tracks. Orbital parameters are selected such that the nodal period of the orbit matches the nodal period of the primary body by a factor dependent on the number of days and the number of revolutions to repeat the ground track. All orbits in a flower constellation have identical orbital elements, with the exception of the right ascension of the ascending node (RAAN) and the initial mean anomaly, which are determined based on the desired phasing scheme desired. Flower constellations have thus far primarily been studied at Earth. A flower constellation at the Moon could be quite useful for science or communication purposes. In this scenario, the flower constellation satellites would be small satellites, which introduces many unique challenges. The cubesats would have limited propulsion capability and would need to be deployed from a mothercraft. Orbital maintenance would then be required after deployment to retain the repeat ground track nature of flower constellations. The limited fuel on the cubesats and the maneuvers required determine the lifetime of the constellation. The communications range of the cubesats will also be limited; following a successful deployment, the mothercraft must move into a long-term communications orbit where it can see both the children craft and Earth, to act as a communications relay. This work investigates the differences in flower constellations at the Moon versus at Earth. It is found that due to the longer rotation period of the Moon, the number of petals in the flower constellation must be quite large in order to produce reasonable orbit sizes. Two types of flower constellations are investigated: a single-petal and multi-petal constellation. The single-petal constellation consists of a string-of-pearls formation within one inertial flower constellation orbit. The multi-petal configuration has one satellite per inertial orbit, with the orbits spaced symmetrically within a 360 degree RAAN distribution. Optimal methods for deployment are explored for both configurations. Phasing orbits are used to deploy the single-petal constellation. This is found to be a simple and low-cost deployment scheme. The multi-petal configuration requires larger plane change maneuvers, and three-burn transfer orbit solutions that are optimal over single impulsive burn maneuvers are found. The mothercraft maneuver into the long-term communications orbit is also investigated. This maneuver is once again just a phase orbit maneuver for the single-petal constellation and is low cost. A polar mothercraft orbit is desired for the multi-petal configuration, again requiring a large and expensive plane change maneuver. As was the case with the deployment maneuver, a three-burn transfer orbit series is found to be cost optimal over a series of impulsive burns for this maneuver. Finally, once the constellation is established, orbit maintenance maneuvers are calculated. A 4 kg cubesat with 1 kg of fuel is assumed, and various thruster types are used to correlate required maintenance Delta-Vs to propellant mass required. It is found that the flower constellations at the Moon can be maintained for between 100 and 800 days, depending on the eciency of the thruster system used. Ultimately, a small satellite constellation at the Moon is found to be feasible to establish and maintain for a science or communication mission.

Identifying the stars on Johann Bayer's Chart of the South Polar Sky
NASA Astrophysics Data System (ADS)
Ridpath, I.
2014-04-01
The first chart of the stars in the region around the south celestial pole was published in 1603 by Johann Bayer (1572-1625) as part of his monumental star atlas called Uranometria. This south polar chart depicted 12 entirely new constellations that had been created only a few years earlier from stars observed during the first Dutch expedition to the East Indies in 1595-97. Bayer's chart plotted 121 stars in the 12 newly invented constellations. Five more stars formed a southern extension of the existing constellation Eridanus, while another twelve stars were left 'unformed', i.e. unattached to any constellation. Whereas Bayer famously applied Greek or Roman letters to the stars in the 48 Ptolemaic constellations, he left the stars in the newly invented constellations unlabelled. This paper attempts to identify the stars plotted on Bayer's chart. It also discusses the source of Bayer's data and the origin of the 12 new southern constellations.

Pepper & Nettle describe possible processes underlying what they call a behavioral constellation of deprivation (BCD). Although we are certain about the application of evolutionary models to our understanding of poverty, we are less certain about the utility of behavioral constellations. The empirical record on poverty-related behaviors is much more divergent and broad than such constellations suggest.

US Food and Drug Administration draft recommendations on radioactive contamination of food
DOE Office of Scientific and Technical Information (OSTI.GOV)
Thompson, D.L.
Recommendations on accidental radioactive contamination of human food were issued in 1982 by the Food and Drug Administration (FDA). The recommendations provided guidance to State and local government officials in the exercise of their respective authorities, and were applicable to emergency response planning and to the conduct of radiation protection activities associated with the production, processing, distribution, and use of human food accidentally contaminated with radioactive material. Review of the 1982 FDA recommendations, stimulated by the events following the 1986 accident at Chernobyl, indicated that it would be appropriate to update the recommendations to incorporate newer scientific information and radiationmore » protection philosophy, to include experience gained since 1982, and to take into account international advances. This paper presents a brief outline of the FDA`s approach to its draft revision. the most recent draft was circulated for interagency review in November 1994. Modification made in response to the comments received are included in this paper. 20 refs., 6 tabs.« less

Development of national legal systems is aimed to establish the public welfare and the protection of the public. Many attempts has been carried out to renew material criminal law and those efforts results in the formulation of the concept of the draft Law Book of the Law of Criminal Law in the form of concept criminal code draft. The basic ideas in drafting rules and regulation based on the values inside the idology of Pancasila are balance among various norm and rules in society. The design concept of the New Criminal Code Act is anticipatory and proactive to formulate provisions on Crime in Cyberspace and Crime on Information and Electronic Transactions. Several issues compiled in this paper are whether the policy in formulation of cyber crime is embodied in the provisions of the current legislation and what the policies formulation of cyber crime is in the concept of the bill book of law - criminal law recently?.

The potential clinical impact of the release of two drafts of the human proteome
Ezkurdia, Iakes; Calvo, Enrique; Del Pozo, Angela; Vázquez, Jesús; Valencia, Alfonso; Tress, Michael L.
2015-01-01
The authors have carried out an investigation of the two “draft maps of the human proteome” published in 2014 in Nature. The findings include an abundance of poor spectra, low-scoring peptide-spectrum matches and incorrectly identified proteins in both these studies, highlighting clear issues with the application of false discovery rates. This noise means that the claims made by the two papers – the identification of high numbers of protein coding genes, the detection of novel coding regions and the draft tissue maps themselves – should be treated with considerable caution. The authors recommend that clinicians and researchers do not use the unfiltered data from these studies. Despite this these studies will inspire further investigation into tissue-based proteomics. As long as this future work has proper quality controls, it could help produce a consensus map of the human proteome and improve our understanding of the processes that underlie health and disease.

2012-01-01
The Space Shuttle program has ended and elements of the Constellation Program have either been cancelled or transitioned to new NASA exploration endeavors. The National Aeronautics and Space Administration (NASA) has worked diligently to select an optimum configuration for the Space Launch System (SLS), a heavy lift vehicle that will provide the foundation for future beyond low earth orbit (LEO) large-scale missions for the next several decades. From Fall 2010 until Spring 2011, an SLS decision-making framework was formulated, tested, fully documented, and applied to multiple SLS vehicle concepts at NASA from previous exploration architecture studies. This was a multistep process that involved performing figure of merit (FOM)-based assessments, creating Pass/Fail gates based on draft threshold requirements, performing a margin-based assessment with supporting statistical analyses, and performing sensitivity analysis on each. This paper focuses on the various steps and methods of this process (rather than specific data) that allowed for competing concepts to be compared across a variety of launch vehicle metrics in support of the successful completion of the SLS Mission Concept Review (MCR) milestone.

Women and traumatic brain injury.
Bell, K R; Pepping, M
2001-02-01
Women with TBI have been inadequately studied in relation to most aspects of pathophysiology, recovery, health and behavioral issues, and community integration. This is not entirely surprising in light of the preponderance of men with TBI but also reflects the traditional tendency of medical researchers to concentrate their efforts on men. Although most of the residual effects of TBI are gender-neutral, women may present some unique problems in relation to pain and endocrine issues, reproduction, and sexual functioning In addition, a woman's roles as wife, mother, and daughter are likely to result in a different constellation of family dynamics when TBI is introduced. Attention to enrollment of women in research studies and the increasing number of multi-institutional studies of TBI may provide enlightenment on these issues in the future.

In the framework of the novel navigation scenario offered by the next generation satellite low thrust autonomous LEO-to-MEO orbit transfer, this study proposes and tests a GNSS based navigation system aimed at providing on-board precise and robust orbit determination strategy to override rising criticalities. The analysis introduces the challenging design issues to simultaneously deal with the variable orbit regime, the electric thrust control and the high orbit GNSS visibility conditions. The Consider Kalman Filtering approach is here proposed as the filtering scheme to process the GNSS raw data provided by a multi-antenna/multi-constellation receiver in presence of uncertain parameters affecting measurements, actuation and spacecraft physical properties. Filter robustness and achievable navigation accuracy are verified using a high fidelity simulation of the low-thrust rising scenario and performance are compared with the one of a standard Extended Kalman Filtering approach to highlight the advantages of the proposed solution. Performance assessment of the developed navigation solution is accomplished for different transfer phases.

Frank, Roslyn M.
The development of the 48 Greek constellations is analyzed as a complex mixture of cognitive layers deriving from different cultural traditions and dating back to different epochs. The analysis begins with a discussion of the zodiacal constellations, goes on to discuss the stellar lore in Homer and Hesiod, and then examines several theories concerning the origins of the southern non-zodiacal constellations. It concludes with a commentary concerning the age and possible cultural significance of stars of the Great Bear constellation in light of ethnohistorical documentation, folklore, and beliefs related to European bear ceremonialism.

In this paper, we first describe an optimal signal constellation design algorithm suitable for the coherent optical channels dominated by the linear phase noise. Then, we modify this algorithm to be suitable for the nonlinear phase noise dominated channels. In optimization procedure, the proposed algorithm uses the cumulative log-likelihood function instead of the Euclidian distance. Further, an LDPC coded modulation scheme is proposed to be used in combination with signal constellations obtained by proposed algorithm. Monte Carlo simulations indicate that the LDPC-coded modulation schemes employing the new constellation sets, obtained by our new signal constellation design algorithm, outperform corresponding QAM constellations significantly in terms of transmission distance and have better nonlinearity tolerance.

The Solar system.Stars and constellations
NASA Astrophysics Data System (ADS)
Horia Minda, Octavian
2017-04-01
It is important for students to understand what is in our Solar System. The Students need to know that there are other things besides the Earth, Sun and Moon in the solar sky. The students will learn about the other eight planets and a few other celestial objects like stars and constellations. Constellations are useful because they can help people to recognize stars in the sky. By looking for patterns, the stars and locations can be much easier to spot. The constellations had uses in ancient times. They were used to help keep track of the calendar. This was very important so that people knew when to plant and harvest crops. Another important use for constellations was navigation. By finding Ursa Minor it is fairly easy to spot the North Star (Polaris). Using the height of the North Star in the sky, navigators could figure out their latitude helping ships to travel across the oceans. Objective: 1. The students will be introduced to the origin of the stars they see at night. 2. They will learn that there are groups of stars called constellations. The students will individually create their own constellations. They will be given the chance to tell the class a small story explaining their constellation. Evaluation of Children: The children will be evaluated through the creation of their constellations and ability to work in groups on the computers.

A study of catasterisms in the 'phaenomena' of Aratus
NASA Astrophysics Data System (ADS)
Rousseau, A.; Dimitrakoudis, S.
We provide a fresh analysis of the constellations in Aratos Phenomena by using the astronomical program Cybersky (by Stephen Schimpf) to check each reference of constellations within the poem for validity in 2800 BCE and 300 BCE (the later accounting for the broader period of time covering Eudoxus of Cnidus and Aratus of Soli). In each case, the latitude of observation was chose to be 36 North in agreement with the area of the sky that is not covered in the descriptions of Aratus (and contains the unseen constellations for a particular latitude). Each constellation was traced back to its Greek mythological origin through tha various writers of antiquity. Our results are collected in a table of the constellations mentioned by Aratus in his epic poem, with respect to the ancient authors who have mentioned each constellation shaping its myth, the locations on the earth each constellation is associated with and the most likely date of observation according to Aratus description and taking into account precession and the proper motion of stars.

The studies that have been carried out on Tethered Constellations are briefly addressed. A definition of a tethered constellation is any number of masses/platforms greater that two connected by tethers in a stable configuration. Configurations and stability constraints are reviewed. Conclusions reached are: (1) The 1-D, horizontal, passively stabilized constellations have been ruled out; (2) Fishbone constellations have been also ruled out; (3) Alternative stable 2-D configurations have been devised such as the quadrangular configuration stabilized by electrodynamic forces (ESC), the quadrangular configuration stabilized by differential air drag (DSC), and the pseudo elliptical configuration stabilized by electrodynamic forces (PEC). Typical dimensions for these constellations are 10 km (horizontal) by 20 km (vertical) with balloon diameters around 100 m in the case of a DSC and a power consumption around 7 KW for an ESC or PEC.

The Sentinel-1 mission has been in operational mode for more than two years, and with the successful commissioning of S1B in Sep 2016, the constellation is now complete. While the InSAR community initially faced many processing challenges due to the introduction of the new TOPS mode, these issues can by now considered resolved. However, truly operational workflows are still to be designed and deployed, and there are a number of integration and interpretation challenges that need to be addressed to achieve operational processing of 6-day revisit InSAR data. In this contribution, we will focus mainly on the integration and interpretation of InSAR products in scientific workflows, rather than on algorithmic details. We will motivate discussion with results obtained from selected pilot sites within the ESA SEOM InSARap project. The sites cover a large part of the application domain for InSAR - "from decimeter to millimeter". Specifically, landslide and corner reflector validation test sites in Norway and Poland will be discussed. The results will serve as basis for a discussion on how to communicate and streamline a portfolio of subsidence products to end users, which is a challenge in itself. We will conclude with a discussion on remaining open questions regarding how we as a community can address these issues to a wider audience.

REVIEW OF DRAFT REVISED BLUE BOOK ON ESTIMATING ...
In 1994, EPA published a report, referred to as the “Blue Book,” which lays out EPA’s current methodology for quantitatively estimating radiogenic cancer risks. A follow-on report made minor adjustments to the previous estimates and presented a partial analysis of the uncertainties in the numerical estimates. In 2006, the National Research Council of the National Academy of Sciences released a report on the health risks from exposure to low levels of ionizing radiation. Cosponsored by the EPA and several other Federal agencies, Health Risks from Exposure to Low Levels of Ionizing Radiation BEIR VII Phase 2 (BEIR VII) primarily addresses cancer and genetic risks from low doses of low-LET radiation. In the draft White Paper: Modifying EPA Radiation Risk Models Based on BEIR VII (White Paper), ORIA proposed changes in EPA’s methodology for estimating radiogenic cancers, based on the contents of BEIR VII and some ancillary information. For the most part, it proposed to adopt the models and methodology recommended in BEIR VII; however, certain modifications and expansions are considered to be desirable or necessary for EPA’s purposes. EPA sought advice from the Agency’s Science Advisory Board on the application of BEIR VII and on issues relating to these modifications and expansions in the Advisory on EPA’s Draft White Paper: Modifying EPA Radiation Risk Models Based on BEIR VII (record # 83044). The SAB issued its Advisory on Jan. 31, 2008 (EPA-SAB-08-

Swarm is the first ESA Earth Observation Mission with three satellites flying in a semi-controlled constellation. The trio is operated from ESA's satellite control centre ESOC in Darmstadt, Germany. The Swarm Flight Operations Segment consists of the typical elements of a satellite control system at ESOC, but had to be carefully tailored for this innovative mission. The main challenge was the multi-satellite system of Swarm, which necessitated the development of a Mission Control System with a multi-domain functionality, both in hardware and software and covering real-time and backup domains. This was driven by the need for extreme flexibility for constellation operations and parallel activities.The three months of commissioning in 2014 were characterized by a very tight and dynamically changing schedule of activities. All operational issues could be solved during that time, including the challenging orbit acquisition phase to achieve the final constellation.Although the formal spacecraft commissioning phase was concluded in spring 2014, the investigations for some payload instruments continue even today. The Electrical Field Instruments are for instance still being tested in order to characterize and improve science data quality. Various test phases also became necessary for the Accelerometers on the Swarm satellites. In order to improve the performance of the GPS Receivers for better scientific exploitation and to minimize the failures due to loss of synchronization, a number of parameter changes were commanded via on-board patches.Finally, to minimize the impact on operations, a new strategy had to be implemented to handle single/multi bit errors in the on-board mass Memories, defining when to ignore and when to restore the memory via a re-initialisation.The poster presentation summarizes the Swarm specific ground segment elements of the FOS and explains some of the extended payload commissioning operations, turning Swarm into a most demanding and challenging mission for the Flight Control Team at ESOC.

The CEOS/GEO Constellation Concept
NASA Technical Reports Server (NTRS)
Cramer, Bryant; Ungar, Stephen
2007-01-01
The Constellation concept was first proposed during a discussion at the 19th CEOS Plenary, in London, in November 2005. The first Paper of the Constellation Concept was presented at the CEOS Strategic Implementation Team meeting (SIT-18), in Frascati, in March 2006, and strongly endorsed by the CEOS Principals. The concept attempts to provide agencies with tools for implementation of the elements that have been previously discussed in international forums (GEO Work Plan, GCOS Implementation Plan). This provides a solid foundation from the community providing requirements. Though agency spending is governed by national requirements, CEOS seeks synergies among member agency programs to fulfil GEOSS requirements, defining guidelines and standards to help agencies to determine from the outset what can be achieved. The constellations concept will allow the development of a commonalties approach among different agencies. At the heart of the application of the Constellations concept is the definition of a series of standards (specific to each Constellation) - required to be satisfied for any mission to be included in the constellation - and a process of recognition/acceptance, whereby an agency applies to SIT to have one or more of its missions (ideally from the outset of planning) recognised as meeting the constellation standards and thereby satisfying the relevant user community needs.

Howard, Joseph; Oza, Dipak; Smith, Danford S.
2006-01-01
This paper presents the best practices used by several commercial and government operators of satellite constellations. These best practices were identified through a series of seminars and discussions held at NASA Goddard Space Flight Center (GSFC). The best practices are arrived through many years of experience and improvements made in the operations procedures and the operational systems with the primary drivers as mission safety and cost effectiveness. This paper discusses the operational aspects associated with how different organizations manage complexities of constellation operations. For the purposes of this paper, satellite constellations are groups of similar spacecraft with more than one spacecraft needed to fully accomplish the constellation's mission

Data Citation Standard: A Means to Support Data Sharing, Attribution, and Traceability
NASA Astrophysics Data System (ADS)
McCallum, I.; Plag, H. P.; Fritz, S.
2012-04-01
Geo-referenced data are crucial for addressing many of the burning societal problems and to support related interdisciplinary research. Data sharing is hampered by the lack of a widely accepted method for giving credit to those who make their data freely available and for tracking the use of data throughout it's life-cycle. Particularly in the scientific community, recognition and renown are important currencies. Providing means for data citation would be a strong incentive for data sharing. Recently, a number of organizations and projects have started to address the concept of data citation (e.g., PANGAEA, NASA DAACS, USGS, NOAA National Data Centers, ESIP, US National Academy of Sciences, and EGIDA). A number of proposals for data citation guidelines have emerged and a better understanding of the many issues at hand is evolving, but to date, no standard has been accepted. This is not surprising, as data citation is far more complicated than citation of scientific publication. Data sets differ in many aspects from standard scientific publications. For example, data sets generally are not locatable and attributable in the same way as scientific publications. Data sets often are not static (introducing versioning), and they are mostly not peer-reviewed (requiring quality control). There is a consensus that the implementation of a standard would reveal new issues that are not obvious today. With the Global Earth Observation System of Systems (GEOSS), the Group on Earth Observations (GEO) is in a unique position to provide the testbed for the implementation of a draft standard. The GEO Plenary supports the implementation of a draft standard developed by the Science and Technology Committee (STC) of GEO with support of the EGIDA Project. This draft is based on guidelines developed by international groups. Currently, users of the GEO-Portal are not obliged or encouraged to cite data accessed through GEOSS - if at all, citation requirements come from the individual data providers. This naturally leads to a at-best non-standard form of data citation or, in the worst case, no data citation at all. The testbed implementation will rectify this situation and help to identify issues not covered by the standard. The process of implementing and iteratively improving the draft is led by the GEO Work Plan Task ID-03 under the Institutions and Development Board; coordinated with the GEO working groups in charge of developing the GEOSS Common Infrastructure (e.g., the Architecture Board, SIF, DSTF, GCI-CT; with other groups within GEO, such as the Data Sharing Task Force, who have initiated similar activities, and with organizations outside of GEO developing the internationally emerging specifications. Metadata for GEOSS data and products may have to be extended to support data citation. It is expected that the availability of a draft citation standard will increase the attractiveness of GEO and GEOSS for scientists by fostering acknowledgment of their contributions when others use them. The testbed implementation will provide valuable insight into issues that need to be addressed and this will be infused into the international discussion on data citation.

Science Opportunities Enabled by NASA's Constellation System: Interim Report
NASA Technical Reports Server (NTRS)
2008-01-01
In 2004 NASA initiated studies of advanced science mission concepts known as the Vision Missions and inspired by a series of NASA roadmap activities conducted in 2003. Also in 2004 NASA began implementation of the first phases of a new space exploration policy, the Vision for Space Exploration. This implementation effort included development of a new human-carrying spacecraft, known as Orion, and two new launch vehicles, the Ares I and Ares V rockets.collectively called the Constellation System. NASA asked the National Research Council (NRC) to evaluate the science opportunities enabled by the Constellation System (see Preface) and to produce an interim report on a short time schedule and a final report by November 2008. The committee notes, however, that the Constellation System and its Orion and Ares vehicles have been justified by NASA and selected in order to enable human exploration beyond low Earth orbit, and not to enable science missions. This interim report of the Committee on Science Opportunities Enabled by NASA s Constellation System evaluates the 11 Vision Mission studies presented to it and groups them into two categories: those more deserving of future study, and those less deserving of future study. Although its statement of task also refers to Earth science missions, the committee points out that the Vision Missions effort was focused on future astronomy, heliophysics, and planetary exploration and did not include any Earth science studies because, at the time, the NRC was conducting the first Earth science decadal survey, and funding Earth science studies as part of the Vision Missions effort would have interfered with that process. Consequently, no Earth science missions are evaluated in this interim report. However, the committee will evaluate any Earth science mission proposal submitted in response to its request for information issued in March 2008 (see Appendix A). The committee based its evaluation of the preexisting Vision Missions studies on two criteria: whether the concepts offered the potential for a significant scientific advance, and whether or not the concepts would benefit from the Constellation System. The committee determined that all of the concepts offered the possibility of a significant scientific advance, but it cautions that such an evaluation ultimately must be made by the decadal survey process, and it emphasizes that this interim report s evaluation should not be considered to be an endorsement of the scientific merit of these proposals, which must of course be evaluated relative to other proposals. The committee determined that seven of these concepts would benefit from the Constellation System, whereas four would not, but it stresses that this conclusion does not reflect an evaluation of the scientific merit of the projects, but rather an assessment of whether or not new capabilities provided by the Constellation System could significantly affect them. Some of the mission concepts, such as the Advanced Compton Telescope, already offer a significant scientific advance and fit easily within the mass and volume constraints of existing launch vehicles. Other mission concepts, such as the Palmer Quest proposal to drill through the Mars polar cap, are not constrained by the launch vehicle, but rather by other technology limitations. The committee evaluated the mission concepts as presented to it, aware nevertheless that proposing a far larger and more ambitious mission with the same science goals might be possible given the capabilities of the Ares V launch vehicle. (Such proposals can be submitted in response to the committee s request for information to be evaluated in its final report.) See Table S.1 for a summary of the Vision Missions, including their cost estimates, technical maturity, and reasons that they might benefit from the Constellation System. The committee developed several findings and recommendations.

Constellation Pharmacology: A new paradigm for drug discovery
Schmidt, Eric W.; Olivera, Baldomero M.
2015-01-01
Constellation Pharmacology is a cell-based high-content phenotypic-screening platform that utilizes subtype-selective pharmacological agents to elucidate the cell-specific combinations (“constellations”) of key signaling proteins that define specific cell types. Heterogeneous populations of native cells, in which the different individual cell types have been identified and characterized, are the foundation for this screening platform. Constellation Pharmacology is useful for screening small molecules or for deconvoluting complex mixtures of biologically-active natural products. This platform has been used to purify natural products and discover their molecular mechanisms. In the on-going development of Constellation Pharmacology, there is a positive-feedback loop between the pharmacological characterization of cell types and screening for new drug candidates. As Constellation Pharmacology is used to discover compounds with novel targeting-selectivity profiles, those new compounds then further help to elucidate the constellations of specific cell types, thereby increasing the content of this high-content platform.

A New Synthesis for the Origin of the Greek Constellations
NASA Astrophysics Data System (ADS)
Schaefer, B. E.
2005-08-01
The Greek constellations constitute one of the longest enduring intellectual properties of humanity. While various papers attribute the origin of the constellations to many diverse possibilities, main stream historians view the origin as largely being in Mesopotamia after around 1350 BC with transmission to the Greeks around 500 BC or so. The evidence for this synthesis is cuneiform and iconographic records that first mention constellations from roughly 1350-500 BC. My recent research on precessional dating has added much detail to this old synthesis. The earliest surviving written description of the Greek constellations is Aratus' Phaenomenon, which is a copy of Eudoxus' lost book of the same name. Hipparchus' Commentary also extensively quotes from Eudoxus. With 172 observations from Eudoxus, I derive a precessional date of 1130 ± 80 BC and a latitude of 36.0 ± 0.9 degrees north. Further, the positioning of the southern void amongst the Greek constellations yields a date of 690 BC (with an uncertainty of 2-4 centuries) and a latitude of 33 degrees (with an uncertainty of 1-3 degrees) for the six southernmost constellations. The earliest surviving description of the Mesopotamian constellations is the MUL.APIN tablet series, with the oldest dated example from the 8th century BC. My precessional calculation gives a date of 1100 BC and a latitude of 33 north. I also see that Eudoxus and MUL.APIN share a substantial number of observations. In all, some Assyrian observer(s) between 33-36 degrees north latitude around the time of 1300-1000 BC apparently invented many of the constellations adopted by the Greeks and made a database of observations later repeated by MUL.APIN, Eudoxus, Aratus, and Hipparchus. But this is not the whole story, as this only accounts for 19 Greek constellations which are identical in stars and representation with the Mesopotamian sky. An additional 12 Greek constellations have the same star groups as the Babylonians yet have completely different mythology/names; and so these representations must have been added by the Greeks. In addition, the Bear constellations must have originated with Paleolithic hunters in northern Eurasia sometime before 11,000 BC, as shown by the widespread distribution of essentially identical myths for the asterism across Eurasia and North America. This leaves about a dozen old constellations which have no Mesopotamian roots and for which the first reference anywhere is from early Greek sources and which have characteristically Greek flavor. Thus it appears that a substantial fraction of the old Greek constellations are actually Greek in origin, with the majority being older asterisms adopted from Mesopotamia, while the Bear originates at least 13,000 years ago. This research was supported in part by the Herbert C. Pollack Award of the Dudley Observatory.

Thoughts on Earned Value Assessments
NASA Technical Reports Server (NTRS)
Pido, Kelle
2009-01-01
This slide presentation reviews the concepts of Earned Value reporting and Earned Value Metrics (EVM) and the implementation for the Constellation Program. EVM is used to manage both the contract and civil service workforce, and used as a measure of contractor costs and performance. The Program EVM is not as useful for Level of Effort tasking, for either contractor, or civil service employees. Some issues and concerns in reference to EVM and the process for the use of EVM for Mission assurance are reviewed,

Measure Guideline: Combustion Safety for Natural Draft Appliances Through Appliance Zone Isolation
DOE Office of Scientific and Technical Information (OSTI.GOV)
Fitzgerald, J.; Bohac, D.
2014-04-01
This measure guideline covers how to assess and carry out the isolation of natural draft combustion appliances from the conditioned space of low-rise residential buildings. It deals with combustion appliances located either within the living space in enclosed closets or side rooms or outside the living space in an adjacent area like an attic or garage. This subset of houses does not require comprehensive combustion safety tests and simplified prescriptive procedures can be used to address safety concerns. This allows residential energy retrofit contractors inexperienced in advanced combustion safety testing to effectively address combustion safety issues and allow energy retrofitsmore » including tightening and changes to distribution and ventilation systems to proceed.« less

In Australasia (Australia and New Zealand) the use of health impact assessment (HIA) as a tool for improved policy development is comparatively new. The public health workforce do not routinely assess the potential health and equity impacts of proposed policies or programs. The Australasian Collaboration for Health Equity Impact Assessment was funded to develop a strategic framework for equity-focused HIA (EFHIA) with the intent of strengthening the ways in which equity is addressed in each step of HIA. The collaboration developed a draft framework for EFHIA that mirrored, but modified the commonly accepted steps of HIA; tested the draft frameworkmore » in six different health service delivery settings; analysed the feedback about application of the draft EFHIA framework and modified it accordingly. The strategic framework shows promise in providing a systematic process for identifying potential differential health impacts and assessing the extent to which these are avoidable and unfair. This paper presents the EFHIA framework and discusses some of the issues that arose in the case study sites undertaking equity-focused HIA.« less

This response on behalf of FRAME to the European Commission's consultation on the five chapters of the Draft Report on Alternative (Non-animal) Methods for Cosmetics Testing: Current Status and Future Prospects--2010, is via a Comment in ATLA, rather than via the template supplied by the Commission. This is principally so that a number of general points about cosmetic ingredient testing can be made. It is concluded that the five draft chapters do not provide a credible basis for the Commission's forthcoming report to the European Parliament and the European Council on the five cosmetic ingredient safety issues for which the 7th Amendment to the Cosmetic Directive's ban on animal testing was postponed until 2013. This is mainly because there is insufficient focus in the draft chapters on the specific nature of cosmetic ingredients, their uses, their local effects and metabolism at their sites of application, and, in particular, on whether their possible absorption into the body would be likely to lead to their accumulation in target sites at levels approaching Thresholds of Toxicological Concern. Meanwhile, there continues to be uncertainty about how the provisions of the Cosmetics Directive should be applied, given the requirements of the REACH system and directives concerned with the safety of other chemicals and products. © 2010 FRAME.

Analysis For Monitoring the Earth Science Afternoon Constellation
NASA Technical Reports Server (NTRS)
Demarest, Peter; Richon, Karen V.; Wright, Frank
2005-01-01
The Earth Science Afternoon Constellation consists of Aqua, Aura, PARASOL, CALIPSO, Cloudsat, and the Orbiting Carbon Observatory (OCO). The coordination of flight dynamics activities between these missions is critical to the safety and success of the Afternoon Constellation. This coordination is based on two main concepts, the control box and the zone-of-exclusion. This paper describes how these two concepts are implemented in the Constellation Coordination System (CCS). The CCS is a collection of tools that enables the collection and distribution of flight dynamics products among the missions, allows cross-mission analyses to be performed through a web-based interface, performs automated analyses to monitor the overall constellation, and notifies the missions of changes in the status of the other missions.

Constellation Space Suit System Development Status

Ross, Amy; Aitchison, Lindsay; Daniel, Brian
2007-01-01
The Constellation Program has initiated the first new flight suit development project since the Extravehicular Mobility Unit (EMU) was developed for the Space Shuttle Program in the 1970s. The Constellation suit system represents a significant challenge to designers in that the system is required to address all space suit functions needed through all missions and mission phases. This is in marked contrast to the EMU, which was designed specifically for micro-gravity space walks. The Constellation suit system must serve in all of the following scenarios: launch, entry and abort crew survival; micro-gravity extravehicular activity (EVA); and lunar (1/6th-gravity) surface EVA. This paper discusses technical efforts performed from May 2006 through February 2007 for the Constellation space suit system pressure garment.

A Case Study Using Modeling and Simulation to Predict Logistics Supply Chain Issues
NASA Technical Reports Server (NTRS)
Tucker, David A.
2007-01-01
Optimization of critical supply chains to deliver thousands of parts, materials, sub-assemblies, and vehicle structures as needed is vital to the success of the Constellation Program. Thorough analysis needs to be performed on the integrated supply chain processes to plan, source, make, deliver, and return critical items efficiently. Process modeling provides simulation technology-based, predictive solutions for supply chain problems which enable decision makers to reduce costs, accelerate cycle time and improve business performance. For example, United Space Alliance, LLC utilized this approach in late 2006 to build simulation models that recreated shuttle orbiter thruster failures and predicted the potential impact of thruster removals on logistics spare assets. The main objective was the early identification of possible problems in providing thruster spares for the remainder of the Shuttle Flight Manifest. After extensive analysis the model results were used to quantify potential problems and led to improvement actions in the supply chain. Similarly the proper modeling and analysis of Constellation parts, materials, operations, and information flows will help ensure the efficiency of the critical logistics supply chains and the overall success of the program.

2011-01-01
Life support systems are a critical part of human exploration beyond low earth orbit. NASA s Altair Lunar Lander team is pursuing efficient solutions to the technical challenges of human spaceflight. Life support design efforts up through Design Analysis Cycle (DAC) 4 focused on finding lightweight and reliable solutions for the Sortie and Outpost missions within the Constellation Program. In DAC-4 and later follow on work, changes were made to add functionality for new requirements accepted by the Altair project, and to update the design as knowledge about certain issues or hardware matured. In DAC-5, the Altair project began to consider mission architectures outside the Constellation baseline. Selecting the optimal life support system design is very sensitive to mission duration. When the mission goals and architecture change several trade studies must be conducted to determine the appropriate design. Finally, several areas of work developed through the Altair project may be applicable to other vehicle concepts for microgravity missions. Maturing the Altair life support system related analysis, design, and requirements can provide important information for developers of a wide range of other human vehicles.

Learning the Constellations: From Junior High to Undergraduate Descriptive Astronomy Class
NASA Astrophysics Data System (ADS)
Stephens, Denise C.; Hintz, Eric G.; Hintz, Maureen; Lawler, Jeannette; Jones, Michael; Bench, Nathan
2015-01-01
As part of two separate studies we have examined the ability of students to learn and remember a group of constellations, bright stars, and deep sky objects. For a group of junior high students we tested their knowledge of only the constellations by giving them a 'constellation quiz' without any instruction. We then provided the students with a lab session, and retested. We also tested a large number of undergraduate students in our descriptive astronomy classes, but in this case there were the same 30 constellations, 17 bright stars, and 3 deep sky objects. The undergraduate students were tested in a number of ways: 1) pre-testing without instruction, 2) self-reporting of knowledge, 3) normal constellation quizzes as part of the class, and 4) retesting students from previous semesters. This provided us with a set of baseline measurements, allowed us to track the learning curve, and test retention of the material. We will present our early analysis of the data.

Science Discoveries Enabled by Hosting Optical Imagers on Commercial Satellite Constellations
NASA Astrophysics Data System (ADS)
Erlandson, R. E.; Kelly, M. A.; Hibbitts, C.; Kumar, C.; Dyrud, L. P.
2012-12-01
The advent of commercial space activities that utilize large space-based constellations provide a new and cost effective opportunity to acquire multi-point observations. Previously, a custom designed space-based constellation, while technically feasible, would require a substantial monetary investment. However, commercial industry has now been entertaining the concept of hosting payloads on their space-based constellations resulting in low-cost access to space. Examples, include the low Earth orbit Iridium Next constellation as well as communication satellites in geostationary. In some of these constellations data distribution can be provided in real time, a feature relevant to applications in the areas of space weather and disaster monitoring. From the perspective of new scientific discoveries enabled by low cost access to space, the cost and thus value proposition is dramatically changed. For example, a constellation of sixty-six satellites (Iridium Next), hosting a single band or multi-spectral imager can now provide observations of the aurora with a spatial resolution of a few hundred meters at all local times and in both hemispheres simultaneously. Remote sensing of clouds is another example where it is now possible to acquire global imagery at resolutions between 100-1000m. Finally, land use imagery is another example where one can use either imaging or spectrographic imagers to solve a multitude of problems. In this work, we will discuss measurement architectures and the multi-disciplinary scientific discoveries that are enable by large space based constellations.

Multi-GNSS signal-in-space range error assessment - Methodology and results
NASA Astrophysics Data System (ADS)
Montenbruck, Oliver; Steigenberger, Peter; Hauschild, André
2018-06-01
The positioning accuracy of global and regional navigation satellite systems (GNSS/RNSS) depends on a variety of influence factors. For constellation-specific performance analyses it has become common practice to separate a geometry-related quality factor (the dilution of precision, DOP) from the measurement and modeling errors of the individual ranging measurements (known as user equivalent range error, UERE). The latter is further divided into user equipment errors and contributions related to the space and control segment. The present study reviews the fundamental concepts and underlying assumptions of signal-in-space range error (SISRE) analyses and presents a harmonized framework for multi-GNSS performance monitoring based on the comparison of broadcast and precise ephemerides. The implications of inconsistent geometric reference points, non-common time systems, and signal-specific range biases are analyzed, and strategies for coping with these issues in the definition and computation of SIS range errors are developed. The presented concepts are, furthermore, applied to current navigation satellite systems, and representative results are presented along with a discussion of constellation-specific problems in their determination. Based on data for the January to December 2017 time frame, representative global average root-mean-square (RMS) SISRE values of 0.2 m, 0.6 m, 1 m, and 2 m are obtained for Galileo, GPS, BeiDou-2, and GLONASS, respectively. Roughly two times larger values apply for the corresponding 95th-percentile values. Overall, the study contributes to a better understanding and harmonization of multi-GNSS SISRE analyses and their use as key performance indicators for the various constellations.

Generally, the motivation for switching from average bioequivalence to population and/or individual bio-equivalence is well recognized in the light of certain limitations of the concept of average bioequivalence. However, this switch still results in unresolved issues which should be addressed before the regulatory guidance is finalized.

Constellation Program Human-System Integration Requirements. Revision E, Nov. 19, 2010
NASA Technical Reports Server (NTRS)
Dory, Jonathan
2010-01-01
The Human-Systems Integration Requirements (HSIR) in this document drive the design of space vehicles, their systems, and equipment with which humans interface in the Constellation Program (CxP). These requirements ensure that the design of Constellation (Cx) systems is centered on the needs, capabilities, and limitations of the human. The HSIR provides requirements to ensure proper integration of human-to-system interfaces. These requirements apply to all mission phases, including pre-launch, ascent, Earth orbit, trans-lunar flight, lunar orbit, lunar landing, lunar ascent, Earth return, Earth entry, Earth landing, post-landing, and recovery. The Constellation Program must meet NASA's Agency-level human rating requirements, which are intended to ensure crew survival without permanent disability. The HSIR provides a key mechanism for achieving human rating of Constellation systems.

Constellation Operations: Lessons Learned For Future Exploration
NASA Technical Reports Server (NTRS)
Kelly, Angelita C.; Case, Warren F.
2006-01-01
The Earth science community has long advocated placing numerous instruments in space to study the Earth and its environment. Space agencies from many countries have responded to this call with a wide range of orbiting satellites. Scientists also envisioned placing some satellites in constellations, to enable diverse remote sensing instruments to observe the same part of the Earth (or its atmosphere) at about the same time, thereby increasing the opportunities for coincident science observations. The Earth Science Afternoon Constellation is answering this call, but there have been unique challenges on the way to its deployment. Currently, the Afternoon Constellation is to comprise six satellites. Three are currently on orbit: NASA's Earth Observing System (EOS)-Aqua (2002) and EOS-Aura (2004), and CNES's Polarization & Anisotropy of Reflectances for Atmospheric Sciences coupled with Observations from a Lidar (PARASOL) (2004). Two more satellites, the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) and Cloudsat, are to be jointly launched in late 2005, followed by the Orbiting Carbon Observatory (OCO) in 2008. The Afternoon Constellation is unlike most satellite constellations in that: 1) It is not a homogenous mix of identical satellites; rather it comprises several satellites with complementary observational capabilities; 2) The satellites are not spaced around the Earth to provide instantaneous, global coverage (as for a communications satellite constellation); rather they orbit in close proximity so observations occur at about the same time over approximately the same region; and 3) Lastly, the satellites are not managed and controlled by one organization; rather the list of organizations is diverse: CNES in France, NASA Centers at Goddard, Langley, and the Jet Propulsion Laboratory, and the US Air Force facility in New Mexico. The PARASOL launch and early orbit (L&EO) phase proved to be a learning experience for constellation members (including Constellation management). Prior to launch, all members signed an operations coordination document that spelled out basic requirements for keeping the constellation safe and resolving non-nominal events. Once PARASOL reached orbit and the mission teams gained experience using the newly-developed constellation monitoring tools, it became clear that some of the guidelines in the signed agreements had to be adjusted. This paper presents the L&EO lessons learned and how they were used to prepare for the next phase - the period following the CloudSat/CALIPSO launch.

This document describes the approach Waste and Environmental Services - Environmental Data and Analysis plans to take to resolve the issues presented in a recent audit of the WES-EDA Environmental Database relative to the RACER database. A majority of the issues discovered in the audit will be resolved in May 2011 when the WES-EDA Environmental Database, along with other LANL databases, are integrated and moved to a new vendor providing an Environmental Information Management (EIM) system that allows reporting capabilities for all users directly from the database. The EIM system will reside in a publicly accessible LANL cloud-based software system.more » When this transition occurs, the data quality, completeness, and access will change significantly. In the remainder of this document, this new structure will be referred to as the LANL Cloud System In general, our plan is to address the issues brought up in this audit in three ways: (1) Data quality issues such as units and detection status, which impinge upon data usability, will be resolved as soon possible so that data quality is maintained. (2) Issues requiring data cleanup, such as look up tables, legacy data, locations, codes, and significant data discrepancies, will be addressed as resources permit. (3) Issues associated with data feed problems will be eliminated by the LANL Cloud System, because there will be no data feed. As discussed in the paragraph above, in the future the data will reside in a publicly accessible system. Note that report writers may choose to convert, adapt, or simplify the information they receive officially through our data base, thereby introducing data discrepancies between the data base and the public report. It is not always possible to incorporate and/or correct these errors when they occur. Issues in the audit will be discussed in the order in which they are presented in the audit report. Clarifications will also be noted as the audit report was a draft document, at the time of this response.« less

To ascertain the frequency and types of patient-reported outcome (PRO) violations made in US pharmaceutical promotional materials between 2006 and 2012 and determine whether there were increases in violation warnings after issuance of the Food and Drug Administration (FDA) draft and final PRO Guidance. All warning letters (WLs) or notices of violation (NOVs) issued by the FDA's Office of Prescription Drug Promotion were reviewed for PRO violations (n = 213). Each letter containing a PRO violation was reviewed to determine the type of violation: 1) PRO measure not fit for purpose, 2) study design/interpretation of results, 3) statistical analysis, and 4) no treatment benefit. Forty-one (19%) letters contained information about PRO infringements. Noticeable spikes in letters were shown in 2007 (37%) and 2010 (31%) after the issuance of the draft and final PRO Guidance, respectively. The most common violation was PRO measure not fit for purpose (54%), specifically: use of individual items (45%), insufficient evidence of content validity (36%), and broadening of the claim beyond what the PRO measures (27%). Issues with study design/interpretation of results were also high (49%), particularly broadening of claim beyond what was measured in the trial (55%) and no PRO measure used (50%). A fifth of the letters issued to companies contained PRO violations, with most related to poor selection of the PRO measure used or trying to broaden the claim. More guidance from the Office of Prescription Drug Promotion about what is considered "substantial evidence" in this area could help reduce the number of letters issued.

On the optimum signal constellation design for high-speed optical transport networks.
Liu, Tao; Djordjevic, Ivan B
2012-08-27
In this paper, we first describe an optimum signal constellation design algorithm, which is optimum in MMSE-sense, called MMSE-OSCD, for channel capacity achieving source distribution. Secondly, we introduce a feedback channel capacity inspired optimum signal constellation design (FCC-OSCD) to further improve the performance of MMSE-OSCD, inspired by the fact that feedback channel capacity is higher than that of systems without feedback. The constellations obtained by FCC-OSCD are, however, OSNR dependent. The optimization is jointly performed together with regular quasi-cyclic low-density parity-check (LDPC) code design. Such obtained coded-modulation scheme, in combination with polarization-multiplexing, is suitable as both 400 Gb/s and multi-Tb/s optical transport enabling technology. Using large girth LDPC code, we demonstrate by Monte Carlo simulations that a 32-ary signal constellation, obtained by FCC-OSCD, outperforms previously proposed optimized 32-ary CIPQ signal constellation by 0.8 dB at BER of 10(-7). On the other hand, the LDPC-coded 16-ary FCC-OSCD outperforms 16-QAM by 1.15 dB at the same BER.

In 2016 the BRITE-Constellation mission had been operational for more than two years. At that time, several hundreds of bright stars of various types had been observed successfully in the two BRITE lters and astonishing new discoveries had been made. Therefore, the time was ripe to host the Second BRITE-Constellation Science Conference: Small satellites | big science" from August 22 to 26, 2016, in the beautiful Madonnensaal of the University of Innsbruck, Austria. With this conference, we brought together the scientic community interested in BRITE-Constellation, pro- vided an update on the status of the mission, presented and discussed latest scientic results, shared our experiences with the data, illustrated successful cooperations between professional and amateur ground-based observers and BRITE scientists, and explored new ideas for future BRITE-Constellation observations.

The New Millenium Program ST-5 Mission: Nanosatellite Constellation Trailblazer
NASA Technical Reports Server (NTRS)
Slavin, James A.
1999-01-01
NASA's New Millenium Program has recently selected the Nanosatellite Constellation Trailblazer (NCT) as its fifth mission (ST-5). NCT will consist of 3 small, very capable and highly autonomous satellites which will be operated as a single "constellation" with minimal ground operations support. Each spacecraft will be approximately 40 cm in diameter by 20 cm in height and weigh only 20 kg. These small satellites will incorporate 8 new technologies essential to the further miniaturization of space science spacecraft which need space flight validation. In this talk we will describe in greater detail the NCT mission concept and goals, the exciting new technologies it will validate, and the role of miniaturized particles and fields sensors in this project. Finally, NCT's pathfinder function for such future NASA missions as Magnetotail Constellation and Inner Magnetosphere Constellation will be discussed.

Bristol Bay Assessment – Supplemental Peer Review Reports ...
These reports represent the results of independent peer reviews of several technical reports submitted to the public docket for the May 2012 draft of the Bristol Bay Assessment, An Assessment of Potential Mining Impacts on Salmon Ecosystems of Bristol Bay, Alaska. Background In May 2012, the U.S. Environmental Protection Agency (USEPA) released the draft assessment entitled An Assessment of Potential Mining Impacts on Salmon Ecosystems of Bristol Bay, Alaska, or the Bristol Bay Assessment. The purpose of the assessment is to provide a characterization of the biological and mineral resources of the Bristol Bay watershed, increase understanding of the potential impacts of large-scale mining on the region’s fish resources, and inform future governmental decisions. During the public comment period for the May 2012 draft, numerous technical reports were submitted to the public docket. The USEPA identified several of these reports as providing information about issues raised by the peer reviewers, but the reports did not show evidence of prior peer review. The USEPA made arrangements for a contractor to conduct independent peer reviews of seven such reports. The reports and the results of these supplemental peer reviews are provided here to document that the reports are of

Failing ethics 101: psychologists, the U.S. military establishment, and human rights.
Boyd, J Wesley; LoCicero, Alice; Malowney, Monica; Aldis, Rajendra; Marlin, Robert P
2014-01-01
The American Psychological Association (APA) has long maintained a close, even symbiotic, relationship with the Department of Defense (DOD) and the Veterans Administration (VA). Herein we highlight these close ties and describe psychologists' participation in interrogations by U.S. military and intelligence entities. We then review the APA's statements about the permissibility of psychologist participation in the interrogation and torture of suspected terrorists. These issues are significant in and of themselves and because the VA and DOD have been described as "growth careers" for psychologists of the future (1). Additionally, the Health Care Personnel Delivery System allows the drafting of civilian clinical psychologists into military service even in the absence of a general draft. In light of psychologists' extensive involvement in the interrogation process of suspected terrorists, and the possibility that psychologists without prior military experience may be drafted, we wondered how much psychologists have been taught about their ethical duties should they find themselves in military settings. The results of our pilot study of U.S. psychology graduate students, which assessed their knowledge of military ethics, raise concerns that psychologists receive inadequate formal training in these matters. This may leave psychologists vulnerable to misinformation about proper ethical conduct in their future work.

Diagnostic criteria for complex medical conditions caused by a multitude of both genetic and environmental factors should be descriptive and avoid any attribution of causality. Furthermore, the wording used to describe a disorder should be evidence-based and avoid stigmatization of the affected individuals. Both terminology and categorizations should be readily comprehensible for healthcare professionals and guide clinical decision making. Uncertainties with respect to diagnostic issues and their implications may be addressed to direct future clinical research. In this context, the European Association of the Study of Obesity (EASO) considers it an important endeavor to review the current ICD-11 Beta Draft for the definition of overweight and obesity and to propose a substantial revision. We aim to provide an overview of the key issues that we deem relevant for the discussion of the diagnostic criteria. We first discuss the current ICD-10 criteria and those proposed in the ICD 11 Beta Draft. We conclude with our own proposal for diagnostic criteria, which we believe will improve the assessment of patients with obesity in a clinically meaningful way. PMID:28738325

Alaska Athabascan stellar astronomy
NASA Astrophysics Data System (ADS)
Cannon, Christopher M.
2014-01-01
Stellar astronomy is a fundamental component of Alaska Athabascan cultures that facilitates time-reckoning, navigation, weather forecasting, and cosmology. Evidence from the linguistic record suggests that a group of stars corresponding to the Big Dipper is the only widely attested constellation across the Northern Athabascan languages. However, instruction from expert Athabascan consultants shows that the correlation of these names with the Big Dipper is only partial. In Alaska Gwich'in, Ahtna, and Upper Tanana languages the Big Dipper is identified as one part of a much larger circumpolar humanoid constellation that spans more than 133 degrees across the sky. The Big Dipper is identified as a tail, while the other remaining asterisms within the humanoid constellation are named using other body part terms. The concept of a whole-sky humanoid constellation provides a single unifying system for mapping the night sky, and the reliance on body-part metaphors renders the system highly mnemonic. By recognizing one part of the constellation the stargazer is immediately able to identify the remaining parts based on an existing mental map of the human body. The circumpolar position of a whole-sky constellation yields a highly functional system that facilitates both navigation and time-reckoning in the subarctic. Northern Athabascan astronomy is not only much richer than previously described; it also provides evidence for a completely novel and previously undocumented way of conceptualizing the sky---one that is unique to the subarctic and uniquely adapted to northern cultures. The concept of a large humanoid constellation may be widespread across the entire subarctic and have great antiquity. In addition, the use of cognate body part terms describing asterisms within humanoid constellations is similarly found in Navajo, suggesting a common ancestor from which Northern and Southern Athabascan stellar naming strategies derived.

Origins of the ancient constellations: I. The Mesopotamian traditions
NASA Astrophysics Data System (ADS)
Rogers, J. H.
1998-02-01
In the sky-map of ancient Babylon, constellations had two different roles, and thus developed into two overlapping traditions. One set of constellations represented the gods and their symbols; the other set represented rustic activities and provided a farming calendar. Many constellations were shared by the two traditions, but in some regions of sky there were alternative divine and rustic figures. These figures developed in stages from ~3200 BC to ~500 BC. Of the divine set, the most important (although the last to be finalised) were the twelve zodiacal signs, plus several associated animals (the serpent, crow, eagle, and fish), which were all transmitted to the classical Greek sky-map that we still use today. Conversely, the rustic constellations of workers and tools and animals were not transmitted to the West. However, a few of them may have survived in Bedouin Arab sky-maps of the first millennium AD.

Constellation labeling optimization for bit-interleaved coded APSK
NASA Astrophysics Data System (ADS)
Xiang, Xingyu; Mo, Zijian; Wang, Zhonghai; Pham, Khanh; Blasch, Erik; Chen, Genshe
2016-05-01
This paper investigates the constellation and mapping optimization for amplitude phase shift keying (APSK) modulation, which is deployed in Digital Video Broadcasting Satellite - Second Generation (DVB-S2) and Digital Video Broadcasting - Satellite services to Handhelds (DVB-SH) broadcasting standards due to its merits of power and spectral efficiency together with the robustness against nonlinear distortion. The mapping optimization is performed for 32-APSK according to combined cost functions related to Euclidean distance and mutual information. A Binary switching algorithm and its modified version are used to minimize the cost function and the estimated error between the original and received data. The optimized constellation mapping is tested by combining DVB-S2 standard Low-Density Parity-Check (LDPC) codes in both Bit-Interleaved Coded Modulation (BICM) and BICM with iterative decoding (BICM-ID) systems. The simulated results validate the proposed constellation labeling optimization scheme which yields better performance against conventional 32-APSK constellation defined in DVB-S2 standard.

Multiple Autonomous Discrete Event Controllers for Constellations

Esposito, Timothy C.
2003-01-01
The Multiple Autonomous Discrete Event Controllers for Constellations (MADECC) project is an effort within the National Aeronautics and Space Administration Goddard Space Flight Center's (NASA/GSFC) Information Systems Division to develop autonomous positioning and attitude control for constellation satellites. It will be accomplished using traditional control theory and advanced coordination algorithms developed by the Johns Hopkins University Applied Physics Laboratory (JHU/APL). This capability will be demonstrated in the discrete event control test-bed located at JHU/APL. This project will be modeled for the Leonardo constellation mission, but is intended to be adaptable to any constellation mission. To develop a common software architecture. the controllers will only model very high-level responses. For instance, after determining that a maneuver must be made. the MADECC system will output B (Delta)V (velocity change) value. Lower level systems must then decide which thrusters to fire and for how long to achieve that (Delta)V.

It has been conjectured that a complete set of mutually unbiased bases in a space of dimension d exists if and only if there is an affine plane of order d. We introduce affine constellations and compare their existence properties with those of mutually unbiased constellations. The observed discrepancies make a deeper relation between the two existence problems unlikely.

Linked Autonomous Interplanetary Satellite Orbit Navigation, or LiAISON, is a novel satellite navigation technique where relative radiometric measurements between two or more spacecraft in a constellation are processed to obtain the absolute state of all spacecraft. The method leverages the asymmetry of the gravity field that the constellation exists in. This paper takes a step forward in developing a high fidelity navigation simulation for the LiAISON concept in an Earth-Moon constellation. In particular, we aim to process two-way Doppler measurements between a satellite in GEO orbit and another in a halo orbit about the Earth-Moon L1 point.

Adaptive software-defined coded modulation for ultra-high-speed optical transport
NASA Astrophysics Data System (ADS)
Djordjevic, Ivan B.; Zhang, Yequn
2013-10-01
In optically-routed networks, different wavelength channels carrying the traffic to different destinations can have quite different optical signal-to-noise ratios (OSNRs) and signal is differently impacted by various channel impairments. Regardless of the data destination, an optical transport system (OTS) must provide the target bit-error rate (BER) performance. To provide target BER regardless of the data destination we adjust the forward error correction (FEC) strength. Depending on the information obtained from the monitoring channels, we select the appropriate code rate matching to the OSNR range that current channel OSNR falls into. To avoid frame synchronization issues, we keep the codeword length fixed independent of the FEC code being employed. The common denominator is the employment of quasi-cyclic (QC-) LDPC codes in FEC. For high-speed implementation, low-complexity LDPC decoding algorithms are needed, and some of them will be described in this invited paper. Instead of conventional QAM based modulation schemes, we employ the signal constellations obtained by optimum signal constellation design (OSCD) algorithm. To improve the spectral efficiency, we perform the simultaneous rate adaptation and signal constellation size selection so that the product of number of bits per symbol × code rate is closest to the channel capacity. Further, we describe the advantages of using 4D signaling instead of polarization-division multiplexed (PDM) QAM, by using the 4D MAP detection, combined with LDPC coding, in a turbo equalization fashion. Finally, to solve the problems related to the limited bandwidth of information infrastructure, high energy consumption, and heterogeneity of optical networks, we describe an adaptive energy-efficient hybrid coded-modulation scheme, which in addition to amplitude, phase, and polarization state employs the spatial modes as additional basis functions for multidimensional coded-modulation.

Hot spots of multivariate extreme anomalies in Earth observations

Anomalies in Earth observations might indicate data quality issues, extremes or the change of underlying processes within a highly multivariate system. Thus, considering the multivariate constellation of variables for extreme detection yields crucial additional information over conventional univariate approaches. We highlight areas in which multivariate extreme anomalies are more likely to occur, i.e. hot spots of extremes in global atmospheric Earth observations that impact the Biosphere. In addition, we present the year of the most unusual multivariate extreme between 2001 and 2013 and show that these coincide with well known high impact extremes. Technically speaking, we account for multivariate extremes by using three sophisticated algorithms adapted from computer science applications. Namely an ensemble of the k-nearest neighbours mean distance, a kernel density estimation and an approach based on recurrences is used. However, the impact of atmosphere extremes on the Biosphere might largely depend on what is considered to be normal, i.e. the shape of the mean seasonal cycle and its inter-annual variability. We identify regions with similar mean seasonality by means of dimensionality reduction in order to estimate in each region both the `normal' variance and robust thresholds for detecting the extremes. In addition, we account for challenges like heteroscedasticity in Northern latitudes. Apart from hot spot areas, those anomalies in the atmosphere time series are of particular interest, which can only be detected by a multivariate approach but not by a simple univariate approach. Such an anomalous constellation of atmosphere variables is of interest if it impacts the Biosphere. The multivariate constellation of such an anomalous part of a time series is shown in one case study indicating that multivariate anomaly detection can provide novel insights into Earth observations.

Dependency of geodynamic parameters on the GNSS constellation
NASA Astrophysics Data System (ADS)
Scaramuzza, Stefano; Dach, Rolf; Beutler, Gerhard; Arnold, Daniel; Sušnik, Andreja; Jäggi, Adrian
2018-01-01
Significant differences in time series of geodynamic parameters determined with different Global Navigation Satellite Systems (GNSS) exist and are only partially explained. We study whether the different number of orbital planes within a particular GNSS contributes to the observed differences by analyzing time series of geocenter coordinates (GCCs) and pole coordinates estimated from several real and virtual GNSS constellations: GPS, GLONASS, a combined GPS/GLONASS constellation, and two virtual GPS sub-systems, which are obtained by splitting up the original GPS constellation into two groups of three orbital planes each. The computed constellation-specific GCCs and pole coordinates are analyzed for systematic differences, and their spectral behavior and formal errors are inspected. We show that the number of orbital planes barely influences the geocenter estimates. GLONASS' larger inclination and formal errors of the orbits seem to be the main reason for the initially observed differences. A smaller number of orbital planes may lead, however, to degradations in the estimates of the pole coordinates. A clear signal at three cycles per year is visible in the spectra of the differences between our estimates of the pole coordinates and the corresponding IERS 08 C04 values. Combinations of two 3-plane systems, even with similar ascending nodes, reduce this signal. The understanding of the relation between the satellite constellations and the resulting geodynamic parameters is important, because the GNSS currently under development, such as the European Galileo and the medium Earth orbit constellation of the Chinese BeiDou system, also consist of only three orbital planes.

The brazilian indigenous planetary-observatory
NASA Astrophysics Data System (ADS)
Afonso, G. B.
2003-08-01
We have performed observations of the sky alongside with the Indians of all Brazilian regions that made it possible localize many indigenous constellations. Some of these constellations are the same as the other South American Indians and Australian aborigines constellations. The scientific community does not have much of this information, which may be lost in one or two generations. In this work, we present a planetary-observatory that we have made in the Park of Science Newton Freire-Maia of Paraná State, in order to popularize the astronomical knowledge of the Brazilian Indians. The planetary consists, essentially, of a sphere of six meters in diameter and a projection cylinder of indigenous constellations. In this planetary we can identify a lot of constellations that we have gotten from the Brazilian Indians; for instance, the four seasonal constellations: the Tapir (spring), the Old Man (summer), the Deer (autumn) and the Rhea (winter). A two-meter height wooden staff that is posted vertically on the horizontal ground similar to a Gnomon and stones aligned with the cardinal points and the soltices directions constitutes the observatory. A stone circle of ten meters in diameter surrounds the staff and the aligned stones. During the day we observe the Sun apparent motions and at night the indigenous constellations. Due to the great community interest in our work, we are designing an itinerant indigenous planetary-observatory to be used in other cities mainly by indigenous and primary schools teachers.

Human Systems Integration (HSI) Case Studies from the NASA Constellation Program
NASA Technical Reports Server (NTRS)
Baggerman, Susan; Berdich, Debbie; Whitmore, Mihriban
2009-01-01
The National Aeronautics and Space Administration (NASA) Constellation Program is responsible for planning and implementing those programs necessary to send human explorers back to the moon, onward to Mars and other destinations in the solar system, and to support missions to the International Space Station. The Constellation Program has the technical management responsibility for all Constellation Projects, including both human rated and non-human rated vehicles such as the Crew Exploration Vehicle, EVA Systems, the Lunar Lander, Lunar Surface Systems, and the Ares I and Ares V rockets. With NASA s new Vision for Space Exploration to send humans beyond Earth orbit, it is critical to consider the human as a system that demands early and continuous user involvement, inclusion in trade offs and analyses, and an iterative "prototype/test/ redesign" process. Personnel at the NASA Johnson Space Center are involved in the Constellation Program at both the Program and Project levels as human system integrators. They ensure that the human is considered as a system, equal to hardware and software vehicle systems. Systems to deliver and support extended human habitation on the moon are extremely complex and unique, presenting new opportunities to employ Human Systems Integration, or HSI practices in the Constellation Program. The purpose of the paper is to show examples of where human systems integration work is successfully employed in the Constellation Program and related Projects, such as in the areas of habitation and early requirements and design concepts.

Infusing Stretch Goal Requirements into the Constellation Program
NASA Technical Reports Server (NTRS)
Lee, Young H.; Galpin, Roger A.; Ingoldsby, Kevin
2008-01-01
In 2004, the Vision for Space Exploration (VSE) was announced by the United States President's Administration in an effort to explore space and to extend a human presence across our solar system. Subsequently, the National Aeronautics and Space Administration (NASA) established the Exploration Systems Mission Directorate (ESMD) to develop a constellation of new capabilities, supporting technologies, and foundational research that allows for the sustained and affordable exploration of space. Then, ESMD specified the primary mission for the Constellation Program to carry out a series of human expeditions, ranging from Low Earth Orbit (LEO) to the surface of Moon, Mars, and beyond for the purposes of conducting human exploration of space. Thus, the Constellation Program was established at the Lyndon B. Johnson Space Center (JSC) to manage the development of the flight and ground infrastructure and systems that can enable continued and extended human access to space. Constellation Program's "Design Objectives" call for an early attention to the program's life cycle costs management through the Program's Need, Goals, and Objectives (NGO) document, which provides the vision, scope, and key areas of focus for the Program. One general policy of the Constellation Program, found in the Constellation Architecture Requirements Document (CARD), states: "A sustainable program hinges on how effectively total life cycle costs are managed. Developmental costs are a key consideration, but total life cycle costs related to the production, processing, and operation of the entire architecture must be accounted for in design decisions sufficiently to ensure future resources are available for ever more ambitious missions into the solar system....It is the intent of the Constellation Program to aggressively manage this aspect of the program using the design policies and simplicity." To respond to the Program's strong desire to manage the program life cycle costs, special efforts were established to identify operability requirements to influence flight vehicle and ground infrastructure design in order to impact the life cycle operations costs, and stretch goal requirements were introduced to the Program. This paper will describe how these stretch goal requirements were identified, developed, refined, matured, approved, and infused into the CARD. The paper will also document several challenges encountered when infusing the stretch goal requirements into the Constellation Program.

Ethics in health sciences librarianship.
Hurych, J M; Glenn, A C
1987-01-01
Against a background of discussion about drafting of an ethical code for librarians and a review of articles confronting ethical issues in librarianship, the authors surveyed the 150 institutional members of the Health Science Librarians of Illinois (HSLI) regarding their perceptions of ethical concerns. Among the issues addressed in the survey are library organization, personnel policies, and professional competency, along with the traditional concerns of professional versus personal values, privacy and confidentiality, access to materials, and materials selection criteria in a health sciences context. Based on a 60% response rate, survey results indicate widespread agreement on some issues and a conspicuous lack of consensus on others. Further research is suggested in order to assess the need for a separate ethical code for health sciences librarians. PMID:3450346

Standard international classification criteria require that classification categories be comprehensive to avoid type II error. Categories should be mutually exclusive and definitions should be clear and unambiguous (to avoid type I and type II errors). In addition, the classification system should be robust enough to last over time and provide comparability between data collections. This article was designed to evaluate the extent to which the classification system contained in the United States Food and Drug Administration 2012 Draft Guidance for the prospective assessment and classification of suicidal ideation and behavior in clinical trials meets these criteria. A critical review is used to assess the extent to which the proposed categories contained in the Food and Drug Administration 2012 Draft Guidance are comprehensive, unambiguous, and robust. Assumptions that underlie the classification system are also explored. The Food and Drug Administration classification system contained in the 2012 Draft Guidance does not capture the full range of suicidal ideation and behavior (type II error). Definitions, moreover, are frequently ambiguous (susceptible to multiple interpretations), and the potential for misclassification (type I and type II errors) is compounded by frequent mismatches in category titles and definitions. These issues have the potential to compromise data comparability within clinical trial sites, across sites, and over time. These problems need to be remedied because of the potential for flawed data output and consequent threats to public health, to research on the safety of medications, and to the search for effective medication treatments for suicidality.

The US Food and Drug Administration (FDA) put out a call for comments on new draft guidance for industry "Comparative Analyses and Related Comparative Use Human Factors Studies for a Drug-Device Combination Product Submitted in an ANDA." This call for comments elicited 7 submissions from various organizations in the field of health care products. This article reports on a review conducted on these 7 submissions. The purpose of this review was to identify any commonalities across the different submissions and determine if there was consensus on any point or aspect of the draft guidance. To identify any commonalities, a heat map plotting the lines of the draft guidance that had raised a comment/suggestion was produced. Also, a thematic analysis was conducted on the comments/suggestions. In total the 7 submissions produced 137 suggestions. The heat map revealed that these suggestions did not focus on any single part of the guidance but were spread throughout the guidance. The thematic analysis conducted on the suggestions found a number of distinct trends. These trends were grouped into 10 primary themes, each with a number of subthemes. It was concluded that guidance from the FDA on this matter is warranted and would be appreciated. However, it was also concluded that based on the distinct trends identified in the suggestions, there are issues that the FDA may wish to consider before publishing their final guidance.

Constellation Program Lessons Learned in the Quantification and Use of Aerodynamic Uncertainty
NASA Technical Reports Server (NTRS)
Walker, Eric L.; Hemsch, Michael J.; Pinier, Jeremy T.; Bibb, Karen L.; Chan, David T.; Hanke, Jeremy L.
2011-01-01
The NASA Constellation Program has worked for the past five years to develop a re- placement for the current Space Transportation System. Of the elements that form the Constellation Program, only two require databases that define aerodynamic environments and their respective uncertainty: the Ares launch vehicles and the Orion crew and launch abort vehicles. Teams were established within the Ares and Orion projects to provide repre- sentative aerodynamic models including both baseline values and quantified uncertainties. A technical team was also formed within the Constellation Program to facilitate integra- tion among the project elements. This paper is a summary of the collective experience of the three teams working with the quantification and use of uncertainty in aerodynamic environments: the Ares and Orion project teams as well as the Constellation integration team. Not all of the lessons learned discussed in this paper could be applied during the course of the program, but they are included in the hope of benefiting future projects.

Toward Beijing: linking HIV / AIDS to other women's issues is imperative.
Forrest, K
1995-01-01
The senior advisor to the AIDSCAP Women's Initiative, Dr. E. Maxine Ankrah, is actively lobbying to secure the inclusion of HIV/AIDS language in the draft platform of the UN Fourth World Conference on Women: Action for Equality, Development and Peace scheduled for September 1995 in Beijing. She organized the only workshop on HIV/AIDS at the preparatory meeting in New York in March 1995. It examined the effects of poverty on the expanding epidemic among females. Workshop presentations included international perspectives on: the effect of structural adjustment programs on women's vulnerability; the relationship between poverty, female prostitution, and AIDS; credit schemes and education to empower rural women; reproductive rights; ethnic issues; and the need for women to help women. Obstacles that obscured the relationships between HIV/AIDS and other women's issues have been: that AIDS was initially defined as a medical problem; that risk groups were narrowly defined; and the emphasis on behavior that blames persons infected with HIV. Despite earlier obstacles, the draft platform has several sections with HIV/AIDS language. Strategic Objective C.3: Undertake Multi-Sectoral Initiatives Sensitive to Women's Life Situations addresses the HIV pandemic and other sexual and reproductive health issues. Some of the actions called for in this objective are involvement of women in decision making, expansion of peer education and outreach, and supporting research of woman-controlled prevention methods. AIDSCAP Women's Initiative and other nongovernmental organizations will work together focus attention on HIV/AIDS in Beijing. AIDSCAP plans to have resource publications available in Beijing as well as to host networking sessions. Unless it is waived, the policy prohibiting HIV-infected persons from entering China will preclude HIV-infected women from taking part in the Conference.

Dark Energy, Dark Matter and Science with Constellation-X
NASA Technical Reports Server (NTRS)
Cardiff, Ann Hornschemeier
2005-01-01
Constellation-X, with more than 100 times the collecting area of any previous spectroscopic mission operating in the 0.25-40 keV bandpass, will enable highthroughput, high spectral resolution studies of sources ranging from the most luminous accreting supermassive black holes in the Universe to the disks around young stars where planets form. This talk will review the updated Constellation-X science case, released in booklet form during summer 2005. The science areas where Constellation-X will have major impact include the exploration of the space-time geometry of black holes spanning nine orders of magnitude in mass and the nature of the dark energy and dark matter which govern the expansion and ultimate fate of the Universe. Constellation-X will also explore processes referred to as "cosmic feedback" whereby mechanical energy, radiation, and chemical elements from star formation and black holes are returned to interstellar and intergalactic medium, profoundly affecting the development of structure in the Universe, and will also probe all the important life cycles of matter, from stellar and planetary birth to stellar death via supernova to stellar endpoints in the form of accreting binaries and supernova remnants. This talk will touch upon all these areas, with particular emphasis on Constellation-X's role in the study of Dark Energy.

The Committee on Earth Observation Satellites is an international group that coordinates civil space-borne observations of the Earth, and provides the space component of the Global Earth Observing System of Systems (GEOSS). The CEOS Virtual Constellations concept was implemented in an effort to engage and coordinate disparate Earth observing programs of CEOS member agencies and ultimately facilitate their contribution in supplying the space-based observations required to satisfy the requirements of the GEOSS. The CEOS initially established Study Teams for four prototype constellations that included precipitation, land surface imaging, ocean surface topography, and atmospheric composition. The basic mission of the Land Surface Imaging (LSI) Constellation [1] is to promote the efficient, effective, and comprehensive collection, distribution, and application of space-acquired image data of the global land surface, especially to meet societal needs of the global population, such as those addressed by the nine Group on Earth Observations (GEO) Societal Benefit Areas (SBAs) of agriculture, biodiversity, climate, disasters, ecosystems, energy, health, water, and weather. The LSI Constellation Portal is the result of an effort to address important goals within the LSI Constellation mission and provide resources to assist in planning for future space missions that might further contribute to meeting those goals.

Design and implementation of satellite formations and constellations
NASA Technical Reports Server (NTRS)
Folta, David; Newman, Lauri Kraft; Quinn, David
1998-01-01
The direction to develop small low cost spacecraft has led many scientists to recognize the advantage of flying spacecraft in constellations and formations to achieve the correlated instrument measurements formerly possible only by flying many instruments on a single large platform. Yet, constellations and formation flying impose additional complications on orbit selection and orbit maintenance, especially when each spacecraft has its own orbit or science requirements. The purpose of this paper is to develop an operational control method for maintenance of these missions. Examples will be taken from the Earth Observing-1 (EO-1) spacecraft that is part of the New Millennium Program (NMP) and from proposed Earth System Science Program Office (ESSPO) constellations. Results can be used to determine the appropriateness of constellations and formation flying for a particular case as well as the operational impacts. Applications to the ESSPO and NMP are highly considered in analysis and applications. After constellation and formation analysis is completed, implementation of a maneuver maintenance strategy becomes the driver. Advances in technology and automation by GSFC's Guidance, Navigation, and Control Center allow more of the burden of the orbit selection and maneuver maintenance to be automated and ultimately placed onboard the spacecraft, mitigating most of the associated operational concerns. This paper presents the GSFC closed-loop control method to fly in either constellations or formations through the use of an autonomous closed loop three-axis navigation control and innovative orbit maintenance support. Simulation results using AutoCon(TM) and FreeFlyer(TM) with various fidelity levels of modeling and algorithms are presented.

Biopsychosocial Characteristics of Children Who Later Murder: A Prospective Study
Lewis, Dorothy Otnow; Moy, Ernest; Jackson, Lori D.; Aaronson, Robert; Restifo, Nicholas; Serra, Susan; Simos, Alexander
2007-01-01
The authors document the childhood neuropsychiatric and family characteristics of nine male subjects who were clinically evaluated as adolescents and were later arrested for murder. Those subjects are compared with 24 incarcerated delinquents who did not go on to commit violent offenses. The future murderers displayed a constellation of biopsychosocial characteristics that included psychotic symptoms, major neurological impairment, a psychotic first-degree relative, violent acts during childhood, and severe physical abuse. The authors relate this combination of factors to prediction of violence and discuss ethical issues that are involved in intervention to prevent violence. PMID:4037127

Streamlining the Design Tradespace for Earth Imaging Constellations
NASA Technical Reports Server (NTRS)
Nag, Sreeja; Hughes, Steven P.; Le Moigne, Jacqueline J.
2016-01-01
Satellite constellations and Distributed Spacecraft Mission (DSM) architectures offer unique benefits to Earth observation scientists and unique challenges to cost estimators. The Cost and Risk (CR) module of the Tradespace Analysis Tool for Constellations (TAT-C) being developed by NASA Goddard seeks to address some of these challenges by providing a new approach to cost modeling, which aggregates existing Cost Estimating Relationships (CER) from respected sources, cost estimating best practices, and data from existing and proposed satellite designs. Cost estimation through this tool is approached from two perspectives: parametric cost estimating relationships and analogous cost estimation techniques. The dual approach utilized within the TAT-C CR module is intended to address prevailing concerns regarding early design stage cost estimates, and offer increased transparency and fidelity by offering two preliminary perspectives on mission cost. This work outlines the existing cost model, details assumptions built into the model, and explains what measures have been taken to address the particular challenges of constellation cost estimating. The risk estimation portion of the TAT-C CR module is still in development and will be presented in future work. The cost estimate produced by the CR module is not intended to be an exact mission valuation, but rather a comparative tool to assist in the exploration of the constellation design tradespace. Previous work has noted that estimating the cost of satellite constellations is difficult given that no comprehensive model for constellation cost estimation has yet been developed, and as such, quantitative assessment of multiple spacecraft missions has many remaining areas of uncertainty. By incorporating well-established CERs with preliminary approaches to approaching these uncertainties, the CR module offers more complete approach to constellation costing than has previously been available to mission architects or Earth scientists seeking to leverage the capabilities of multiple spacecraft working in support of a common goal.

Clinical guidelines for the treatment of depressive disorders. II. Principles of management.
Reesal, R T; Lam, R W
2001-06-01
The Canadian Psychiatric Association and the Canadian Network for Mood and Anxiety Treatments partnered to produce clinical guidelines for psychiatrists for the treatment of depressive disorders. A standard guidelines development process was followed. Relevant literature was identified using a computerized Medline search supplemented by review of bibliographies. Operational criteria were used to rate the quality of scientific evidence, and the line of treatment recommendations included consensus clinical opinion. This section on "Principles of Management" is 1 of 7 articles drafted and reviewed by clinicians. Revised drafts underwent national and international expert peer review. The principles and goals of psychiatric management with psychotherapy and pharmacotherapy are reviewed. Two phases of treatment, acute and maintenance, are identified. Special topics, including inpatient management, suicide management, and medical-legal issues are also discussed. These principles of psychiatric management provide a framework for the use of specific treatments for depressive disorders.

NASA has used procedures to describe activities to be performed onboard vehicles by astronaut crew and on the ground by flight controllers since Apollo. Starting with later Space Shuttle missions and the International Space Station, NASA moved forward to electronic presentation of procedures. For the Constellation Program, another large step forward is being taken - to make procedures more interactive with the vehicle and to assist the crew in controlling the vehicle more efficiently and with less error. The overall name for the project is the Constellation Procedure Applications Software System (CxPASS). This paper describes some of the history behind this effort, the key concepts and operational paradigms that the work is based upon, and the actual products being developed to implement procedures for Constellation

The long-forgotten debate of 1929-31 between T. L. Kelley and W. H. Kilpatrick is reviewed with the aim of reviving the crucial, but dormant, issue of the competence of quantitative empirical research to answer educational questions. They debated the need to supplement scientific method with a philosophical approach sensitive to needs, impulses,…

To address the standardization issues of perceptually based image quality for printing systems, ISO/IEC JTC1/SC28, the standardization committee for office equipment chartered the W1.1 project with the responsibility of drafting a proposal for an international standard for the evaluation of printed image quality1. An ISO draft Standard2, ISO/WD 19751-1, Office Equipment - Appearance-based image quality standards for printers - Part 1: Overview, Procedure and Common Methods, 2004 describes the overview of this multi-part appearance-based image quality standard. One of the ISO 19751 multi-part Standard"s tasks is to address the appearance-based gloss and gloss uniformity issues (in ISO 19751-2). This paper summarizes the current status and technical progress since the last two updates3, 4. In particular, we will be discussion our attempt to include 75 degree gloss (G75) objective measurement5 in differential gloss and within-page gloss uniformity. The result for a round-robin experiment involving objective measurement of differential gloss using G60 and G75 gloss measurement geometry is described. The results for two perceptual-based round-robin experiments relating to haze effect on the perception of gloss, and gloss artifacts (gloss streaks/bands, gloss graininess/mottle) are discussed.

Materno-infantilism, feminism and maternal health policy in Brazil.
Diniz, Simone
2012-06-01
In the last days of 2011, President of Brazil Dilma Rousseff issued a provisional measure (or draft law) entitled "National Surveillance and Monitoring Registration System for the Prevention of Maternal Mortality" (MP 557), as part of a new maternal health programme. It was supposed to address the pressing issue of maternal morbidity and mortality in Brazil, but instead it caused an explosive controversy because it used terms such as nascituro (unborn child) and proposed the compulsory registration of every pregnancy. After intense protests by feminist and human rights groups that this law was unconstitutional, violated women's right to privacy and threatened our already limited reproductive rights, the measure was revised in January 2012, omitting "the unborn child" but not the mandatory registration of pregnancy. Unfortunately, neither version of the draft law addresses the two main problems with maternal health in Brazil: the over-medicalisation of childbirth and its adverse effects, and the need for safe, legal abortion. The content of this measure itself reflects the conflictive nature of public policies on reproductive health in Brazil and how they are shaped by close links between different levels of government and political parties, and religious and professional sectors.

The Food and Drug Administration (FDA or Agency) is announcing the availability of guidances for industry entitled ``E2C(R2) Periodic Benefit-Risk Evaluation'' (E2C(R2) guidance) and ``E2C(R2) Periodic Benefit-Risk Evaluation Report--Questions and Answers'' (E2C(R2) Q&A guidance). These guidances were prepared under the auspices of the International Council for Harmonisation (ICH), formerly the International Conference on Harmonisation. The E2C(R2) draft guidance, issued April 11, 2012, updated and combined two ICH guidances, ``E2C Clinical Safety Data Management: Periodic Safety Update Reports for Marketed Drugs'' (E2C guidance) and ``Addendum to E2C Clinical Safety Data Management: Periodic Safety Update Reports for Marketed Drugs'' (addendum to the E2C guidance). The E2C(R2) guidance is intended to describe the format, content, and timing of a Periodic Benefit-Risk Evaluation Report (PBRER) for an approved drug or biologic, and it finalizes the draft guidance. The E2C(R2) Q&A guidance is a supplementary guidance that is intended to clarify key issues in the E2C(R2) guidance.
