Operating model satellite for space education  

NASA Astrophysics Data System (ADS)

Satellite technology is still a deep mystery for most of the people in the world, because there is little access to satellites, even through the media. A process has been devised to build a low-cost educational cardboard model of a communication satellite, using light beams to simulate the radio links. The construction of the model follows closely the construction process of a real satellite, and can help to understand the general technology, while producing an attractive "toy."

Space education  

NASA Astrophysics Data System (ADS)

An essential pre-requisite to a successful space technology applications programme is the building of various indigenous capacities, particularly human resources. Efforts to accomplish such a capacity-building must be devoted, at the local level, to the development of necessary high-level knowledge and expertise in space science and technology fields. Such a programme must also focus on long-term in-depth education and research opportunities in the developing countries, where the beneficiaries would gain an in-depth understanding and appreciation of not only the application potentials of a given technology but also an insight into why and how the technology works the way it does. In recognition of such a pre-requisite, it is universally acknowledged that if effective assimilation of space science and appropriate application of space technology are to succeed in the developing countries, and particularly if such a discipline as satellite remote sensing is to transcend its current image of being a technology-driven tool into a user-driven one, efforts must be devoted, at the local level, to the development of necessary high-level knowledge and expertise in requisite space science and technology fields. The justification for such an in-depth education is not far-fetched particularly as one reflects on the myriad of space science and technology activities that are both in progress and are planned. Aspects of these are reflected in this paper.

Community Coordinated Modeling Center tools for solar and space physics higher education  

NASA Astrophysics Data System (ADS)

Community Coordinated Modeling Center (CCMC) has developed over the years a comprehensive set of tools that are directly applicable to higher education. The tools range from standard runs-on-request system providing access to state-of-the-art solar and space physics models to online tutorials on space weather analysis. CCMC has also supported directly, for example, by means of tailored simulations and web interfaces various educational activities such as CISM and Heliophysics Summer Schools. In this paper we provide a brief overview of CCMC tools that can benefit a variety of educational efforts. We will discuss, for example, the usage of integrated Space Weather Analysis (iSWA) system, CCMC runs-on-request system, advanced visualizations tools such as Space Weather Explorer 2 and other publicly available CCMC material in higher education. We will give explicit examples of some of our success stories and outline our envisioned higher education path forward. The main portals to CCMC's educational material are ccmc.gsfc.nasa.gov and iswa.gsfc.nasa.gov.

Four educational programs in Space Life Sciences.  

PubMed

Four different educational programs impacting Space Life Sciences are described: the NASA/USRA Advanced Design Program, the NASA Specialized Center of Research and Training (NSCORT) Program, the Centers for the Commercial Development of Space (CCDS) Program, and the NASA Graduate Research Fellow Program. Each program makes somewhat different demands on the students engaged in them. Each program, at the University of Colorado, involves Space Life Sciences training. While the Graduate Student Research Fellow and NSCORT Programs are discipline oriented, the Advanced Design and CCDS Programs are focused on design, technologies and applications. Clearly, the "training paradigms" differ for these educational endeavors. But, these paradigms can be made to mutually facilitate enthusiasm and motivation. Discipline-oriented academic programs, ideally, must be flexible enough to accommodate the emergent cross-disciplinary needs of Space Life Sciences students. Models for such flexibility and resultant student performance levels are discussed based upon actual academic and professional records. PMID:11537954

Symposium on "Space and education"  

NASA Astrophysics Data System (ADS)

The purpose of the symposium is to encourage agencies, businessmen and teachers from all countries to share their ideas, programmes and strategies to meet the needs of primary and secondary school pupils and university students and provide in-service training for professionals in the space industry. States are constantly required to meet the challenge of ensuring that educational methods keep pace with a changing world. The new technologies loom ever larger in our daily lives and we must all be given an opportunity to familiarise ourselves with this aspect of the modern world and extend the boundaries of our knowledge by taking part in the rapid advances in this area. Space applications too play an increasing part in our lives, pointing the way to the future. Space can be an excellent adjunct to education, contributing to a better understanding of the world around us and providing young people with the basic knowledge that is an essential part of their training. Space activities play a key role in prompting explorers, pioneers and inventors to press forward, to provide a source of innovation at the service of mankind and improve our quality of life. The space industry and space agencies can contribute to national education by providing and maintaining programmes at all levels and using the most effective teaching methods to foster enthusiasm for space among the young and encourage them to work in that sector later. The symposium will open with an official ceremony at 9.30 on Monday 3 April, and end with a formal dinner on Wednesday 5 April. The programme will include plenary sessions and workshops, starting with four plenary sessions: two on Monday, at which representatives of space firms and agencies will speak, and two on Tuesday morning, at which teachers, students and pupils, will have their say. These will be followed by five workshops, to be held on Tuesday afternoon and Wednesday morning. Media representatives wishing to attend the Symposium are asked to complete the attached form and return it by fax to 01.44.76.7816 by 27.3.2000.

Popularizing Space Education in Indian Context  

NASA Astrophysics Data System (ADS)

Indians have many mythological stories about many constellations and stars. Hindu months are based on MOON and 27 stars on Zodiac. They are very important for many Indians in ritual, religious functions. By prompting them to identify their birth star, really makes them elevated. Similarly conveying them the importance of star gazing with respect to their day today life makes them to take interest and active participation in Space Activities. Space activities should be driven by public; their requirements; their dreams and imaginations. Their active participation definitely gives valuable inputs to space scientists. Hence, there is a need of involving common man or public mass by appropriate motivation by organising sky gazing sessions, exhibitions, workshops, etc. In this connection, even if the some organisation are able to attract a small percent of qualified engineers/scientists,, enthusiastic students, it would result in the creation of a sizable pool of talent in space sciences,which may well determine the future mankind on this planet. Some simple motivation acts have made the people to take interest in space. we have been using certain methodologies to popularize space science - 1] Conducting theory sessions on basics of star gazing and conveying importance of sky gazing with respect to day-today life. 2] Organising seminars, workshops, lectures and other academic/popular science activities with special reference to space science 3] Projects - a] Cubsat Missions b] Automatic Weather Station Facility c] Model making d] Creating and simulating space models and rover making competitions. The 50 year's of Exploration has left tremendous impact on many society's working towards space education and exploration.

Global partnerships: Expanding the frontiers of space exploration education  

NASA Astrophysics Data System (ADS)

Globalization is creating an interdependent space-faring world and new opportunities for international partnerships that strengthen space knowledge development and transfer. These opportunities have been codified in the Global Exploration Strategy, which endorses the "inspirational and educational value of space exploration" [1]. Also, during the 2010 Heads of Space Agencies Summit celebrating the International Academy of Astronautics' (IAA) 50th Anniversary, space-faring nations from across the globe issued a collective call in support of robust international partnerships to expand the frontiers of space exploration and generate knowledge for improving life on Earth [2]. Educators play a unique role in this mission, developing strategic partnerships and sharing best educational practices to (1) further global understanding of the benefits of space exploration for life on Earth and (2) prepare the next generation of scientists required for the 21st Century space workforce. Educational Outreach (EO) programs use evidence-based, measurable outcomes strategies and cutting edge information technologies to transfer space-based science, technology, engineering and mathematics (STEM) knowledge to new audiences; create indigenous materials with cultural resonance for emerging space societies; support teacher professional development; and contribute to workforce development initiatives that inspire and prepare new cohorts of students for space exploration careers. The National Space Biomedical Research Institute (NSBRI), the National Aeronautics and Space Administration (NASA) and Morehouse School of Medicine (MSM) have sustained a 13-year space science education partnership dedicated to these objectives. This paper briefly describes the design and achievements of NSBRI's educational programs, with special emphasis on those initiatives' involvement with IAA and the International Astronautical Congress (IAC). The IAA Commission 2 Draft Report, Space for Africa, is discussed as a model for developing sustainable partnerships and indigenous programs that support Africa's steady emergence as a global space-faring force. The IAC will provide timely: 2011 South Africa will provide timely feedback to refine that report's strategies for space life sciences education and public engagement in Africa and around the globe.

Educational space probe model system of lander (Hunveyor), rover (Husar) and test-terrain for planetary science education and analog studies in universities and colleges of Hungary.  

NASA Astrophysics Data System (ADS)

In 1997 we began a complex modelling program in planetary geology unifying field work robotics, electronics and complex environmental analysis by constructing an experimental space probe model system. It consists of an experimental lander HUNVEYOR (Hungarian UNiversity surVEYOR), a rover named HUSAR (Hungarian University Surface Analyser Rover) and a test terrain. For Hunveyor the idea and example was the historical Surveyor program of NASA in the 1960-ies, for the Husar the idea and example was the Pathfinder's rover Sojouner rover. The main goals of this program are: 1) to teach the complex work of planetary science according to the main operations of the procedure of the large scientific and technology system, 2) to build the lander structure and basic electronics from cheap everyday PC compatible elements, 3) to construct basic experiments and their instruments, 4) to use the system as a space activity simulator, 5) to form the electronics of this simulator system which contains lander (with on board computer) for works on a test planetary surface, and a "terrestrial control" computer, "talking" with each other, 6) to harmonize the assemblage of the electronic system and instruments in various levels of autonomy from the power and communication circuits, 7) to use the complex system in education for in situ understanding of the complex planetary environmental problems, 8) to build various planetary environments on the test terrain in order to apply the instrument assemblages in various testing conditions, 9) to use the model system with special internet connections capable of communicating in the web in field trip conditions for users, and 10) to use the model system in real planetary analog field trip simulations, first in Hungary and later in some planetary analog site in the world. We report some of these visits in Hungary and Utah, USA. REFERENCES: [1] Bérczi Sz., Cech V., Hegyi S., Borbola T., Diósy T., Köll? Z., o 1 Tóth Sz.

Radiation Storm vs. The Magnetic Shield: Superheroes of Magnetism & Space Weather Education - A Model for Teacher Professional Development Workshops  

NASA Astrophysics Data System (ADS)

Magnetic and electric fields and phenomena play important roles in various situations in astronomy, planetary science, and Earth science. Students often lack an intuitive sense of electromagnetic phenomena, and therefore struggle with the complexities of planetary and stellar magnetic fields. Hands-on magnetism activities can provide students with an intuitive grasp of the basics of magnetism, preparing them for more challenging conceptual studies of magnetic phenomena. For the past six years, we have been presenting a professional development workshop for teachers covering the topics of magnetism and space weather. The workshop, which has been conducted more than 20 times for a range of audiences, blends together several simple hands-on activities, background information on space weather and geomagnetism, a collection of images, animations, and interactives that illustrate important concepts, and guidance about specific links between these topics and national science education standards. These workshops have been very well-received, and have consistently been rated highly by participants in surveys. We believe the methods used in these workshops can be applied to other topics in science education and to astronomy and Earth science education specifically. In this presentation, we will describe our magnetism and space weather workshop, including some of the hands-on activities. We will describe successful aspects of the workshop and comment on ways we think this approach could be replicated for other topics. We will also display some of the interactives, graphics, and animations shown during the workshops. Resources have been added to the workshop over the years in response to recurring questions from teachers; we will comment on this process and how it might be applied to other topics. The activities and extensive background content used or referenced in the workshop are available for free on the Windows to the Universe web site (www.windows2universe.org). Hands on activities can help students gain an intuitive grasp for natural phenomena. Iron filings and a horseshoe magnet help learners comprehend the magnetic fields above sunspot pairs.

Educational Outreach: The Space Science Road Show  

NASA Astrophysics Data System (ADS)

The poster presented will give an overview of a study towards a "Space Road Show". The topic of this show is space science. The target group is adolescents, aged 12 to 15, at Dutch high schools. The show and its accompanying experiments would be supported with suitable educational material. Science teachers at schools can decide for themselves if they want to use this material in advance, afterwards or not at all. The aims of this outreach effort are: to motivate students for space science and engineering, to help them understand the importance of (space) research, to give them a positive feeling about the possibilities offered by space and in the process give them useful knowledge on space basics. The show revolves around three main themes: applications, science and society. First the students will get some historical background on the importance of space/astronomy to civilization. Secondly they will learn more about novel uses of space. On the one hand they will learn of "Views on Earth" involving technologies like Remote Sensing (or Spying), Communication, Broadcasting, GPS and Telemedicine. On the other hand they will experience "Views on Space" illustrated by past, present and future space research missions, like the space exploration missions (Cassini/Huygens, Mars Express and Rosetta) and the astronomy missions (Soho and XMM). Meanwhile, the students will learn more about the technology of launchers and satellites needed to accomplish these space missions. Throughout the show and especially towards the end attention will be paid to the third theme "Why go to space"? Other reasons for people to get into space will be explored. An important question in this is the commercial (manned) exploration of space. Thus, the questions of benefit of space to society are integrated in the entire show. It raises some fundamental questions about the effects of space travel on our environment, poverty and other moral issues. The show attempts to connect scientific with community thought. The difficulty with a show this elaborate and intricate is communicating on a level understandable for teenagers, whilst not treating them like children. Professional space scientists know how easy it is to lose oneself in technical specifics. This would, of course, only confuse young people. The author would like to discuss the ideas for this show with a knowledgeable audience and hopefully get some (constructive) feedback.

The virtual space exploration education portal  

NASA Astrophysics Data System (ADS)

New information technologies have evolved from space exploration—3-D visualisation ‘lenses’ and a growing suite of tools that allow access to exploration, analysis and interpretation of often complex information by a range of end users including the public, communicators, and policy makers. These tools have only become viable in the past year or two with the combination of the availability of inexpensive, but powerful, personal computers and widespread use of the Internet. A new study group under Commission 6 has been established, entitled ‘Future Directions of Space Exploration Education’, to build a Virtual Global Space Exploration Education Portal (VGSEEP) to open this revolution to all audiences, not just students. This paper describes the initial stages of VGSEEP. The NASA Learning Technologies suite of ‘lenses’ and tools will be demonstrated: World Wind, a 3-D globe that provides insights into our planet from space and almost down to ground level; the Virtual Field Trip that explores at ground level in 3-D; the Virtual Lab, which allows a range of samples to be examined via a virtual light microscope and/or a Scanning Electron Microscope and What’s the Difference?, which allows users to manipulate information in a multi-graphical interface.

Mathematical Model of the Public Understanding of Space Science  

NASA Astrophysics Data System (ADS)

The success in deployment of the space programs now in many respects depends on comprehension by the citizens of necessity of programs, from "space" erudition of country. Purposefulness and efficiency of the "space" teaching and educational activity depend on knowledge of relationships between separate variables of such process. The empirical methods of ``space'' well-information of the taxpayers should be supplemented by theoretical models permitting to demonstrate a ways of control by these processes. Authors on the basis of their experience of educational activity during 50- years of among the students of space-rocket profession obtain an equation of ``space" state of the society determining a degree of its knowledge about Space, about achievements in its development, about indispensable lines of investigations, rates of informatization of the population. It is supposed, that the change of the space information consists of two parts: (1) - from going of the information about practical achievements, about development special knowledge requiring of independent financing, and (2) from intensity of dissemination of the ``free" information of a general educational line going to the population through mass-media, book, in family, in educational institutions, as a part of obligatory knowledge of any man, etc. In proposed model the level space well-information of the population depends on intensity of dissemination in the society of the space information, and also from a volume of financing of space-rocket technology, from a part of population of the employment in the space-rocket programs, from a factor of education of the population in adherence to space problems, from welfare and mentality of the people, from a rate of unemployment and material inequality. Obtained in the report on these principles the equation of a space state of the society corresponds to catastrophe such as cusp, the analysis has shown which one ways of control of the public understanding of space science. The boundary sectioning area of effective and unefficient modes of training and education of the population of country in space spirit is determined.

Understanding Models in Earth and Space Science  

NSDL National Science Digital Library

It's a challenge educators at all grade levels face: How do you teach subjects your students can't see, touch, or hear? You do it with models--which have gained new importance since the National Science Education Standards specifically recommended using models as an organizing framework for teaching and understanding science. Whether your lessons concern molecules or Mars, Understanding Models in Earth and Space Science offers practical guidance. It's designed to help you understand the full range of models available to illustrate abstract concepts, demonstrate complex ideas, or teach about things students can't see. The book provides an in-depth look at specific kinds of models--what they are, how they can be designed, the best ways to use them, and possible shortcomings. Among the chapter topics are concrete models; mathematical models; similes, analogies, and metaphors; computer models; and inquiry and model building. Itself a model of good modeling, the book offers abundant examples (including drawing parallels between seemingly unrelated topics, such as how tornadoes are like vacuum cleaners) and plentiful background specific to Earth science teachers. Understanding Models is the result of a partnership between NSTA and the U.S. Environmental Protection Agency's Office of Pollution Prevention and Toxics.

Space education and outreach symposium (E1.). Structures for space education (2.)  

NASA Astrophysics Data System (ADS)

The Brazilian Space Agency (AEB) sponsors an outreach program aimed at promoting Brazilian space activities among students and teachers of primary and secondary schools. The program, called AEB Escola (Brazilian Space Agency School), was created in 2003 and, since then, has taken the space theme to thousands of students and teachers. The main goal of the AEB Escola Program is to make the Brazilian Space Program known among students and teachers. Additionally, it intends to use the space theme as a way to increase youth interest in studies in general, and in sciences in particular. The program focuses on teachers who, ultimately, are the ones responsible for introducing the subject to their students. And who also guarantee the continuity of the Program. An Astronautics and Space Science course is given to teachers by researchers involved with the Brazilian Space Program activities. The course has over 100 h of activities covering the following themes: Astronomy, Satellite Launcher Vehicles, Satellites and Space Platforms, Remote Sensing, Meteorology and Environmental Sciences, and Projects's Learning. The AEB Escola Program also promotes many other activities among students including lectures, contests, interactive exhibitions and hands-on activities. One of the consequences of such initiatives was the creation of two experiments taken to the International Space Station in April 2006 by the Brazilian astronaut, Marcos Pontes. Moreover, a nationwide contest called Brazilian Astronomy and Astronautical Olympics (OBA) is held every year involving nearly half a million students, with ages ranging from 7 to 17. The top five students are taken to the International Astronomy Olympics, where Brazil has obtained many medals. The top 50 students of OBA are taken, along with their teachers, to the city of Săo José dos Campos, in the state of Săo Paulo, to participate in the Space Journey event. The journey lasts a week during which the participants get a chance to learn about the activities and infrastructure of the National Institute of Space Research (INPE) and the Institute of Aeronautics and Space (IAE), the leading Brazilian institutions linked to Space activities. The material used by the teachers is produced by a net of partners, including universities and the Brazilian Ministry of Education. The material is produced both in printed and electronics format: CDs and DVDs, being distributed, free of charge, to thousands of schools. The paper introduces the concepts, methods, achievements and perspectives of the AEB Escola Program.

Ejs Phase Space Plotter Model  

NSDL National Science Digital Library

The Ejs Phase Space Plotter model displays the dynamics of an ensemble of pendula or simple harmonic oscillators in phase space (velocity versus position). Friction is initially set to zero but can be changed via a textbox as can the number of elements in the ensemble. For the pendulum ensemble, the Cylinder checkbox keeps the angular position between âpi and pi for large initial angular velocities. You can modify this simulation if you have Ejs installed by right-clicking within the plot and selecting âOpen Ejs Modelâ from the pop-up menu item. Ejs Phase Space Plotter model was created using the Easy Java Simulations (Ejs) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the ejs_ehu_analytical_mechanics_phase_space.jar file will run the program if Java is installed. Ejs is a part of the Open Source Physics Project and is designed to make it easier to access, modify, and generate computer models. Additional Ejs models for Newtonian mechanics are available. They can be found by searching ComPADRE for Open Source Physics, OSP, or Ejs.

Space Education in Australia: Public Education and Outreach Through Peer Mentoring  

NASA Astrophysics Data System (ADS)

In Australia, the number of space education programs aimed at secondary and tertiary students has dramatically increased over the last decade. The majority of these programs are organised by young tertiary-educated volunteers with a passion for space; this mode of education is described as `peer mentoring'. Identifying characteristics of peer mentored programs include increased emphasis on the vocational relevance of the educational material presented, and constant updating of course content and mode of delivery. These educational programs and their activities are discussed. Space education in Australia has benefited greatly from the employment of peer mentoring. The ability of the students to relate to the organisers of the space education experience is a vital part of making sure that the experience is circulated out into the general public through families and friends. Peer mentoring also employs an `educate to educate' philosophy, in which graduates of these space education programs are encouraged to become mentors for future programs. To `educate to educate' is to develop `sustainable education', and with a sustainable educational base comes the best chance for developing a sustainable base of highly motivated and educated space pioneers.

The main purpose of the space sciences education program developed in Moscow State University is to incorporate modern space research in the university and high education and popularize basics of space physics. The First Russian University Satellite "Universitetskiy-Tatyana" launched on January 20, 2005 formed a basis for development of a new approach to the space-physics education. The onboard scientific complex, as well as the mission control and information-receiving center, was designed and developed in Moscow State University. The scientific program of the mission includes measurements of space radiation in various energy ranges, and UV luminosity and lightening from the Earth. Educational materials are concentrated to upper high school, junior and senior university levels. There was developed a special computerized hands-on exercises based on the experimental quasi-realtime data obtained from "Universitetskiy-Tatyana" satellite and other internet resources. Students specialized in space physics from several Russian universities are involved in scientific work based on various scientific data. Moscow State University is now extending its space science education program by creation the electronic textbooks on remote sensing, space factors and materials study, satellite design and development, etc. "Space schools" for university teachers and students were held in 2004 - 2007. The main objective of these schools was to attract interest to space research. The mutual idea of these schools was to join forces of Moscow State University scientists, university teachers and students. For modern university world, it is very important to understand what skills future space scientists and space industry employees must be equipped with. The space sciences educational activity of Moscow State University is a non-profit project and is open for all interested parties.

Space Sciences in the classroom: Educational activities of the European Space Agency  

NASA Astrophysics Data System (ADS)

Education is among the basic, mandatory activities of the European Space Agency (ESA) and aims at all educational levels, from primary school to post-graduate. The primary objective of the ESA educational activities is to enhance the literacy of young people in science and technology and to stimulate interest in STEM (Science - Technology - Engineering - Mathematics) studies and careers, using Space as a theme. The activities mostly follow the IBSE paradigm (Inquiry-Based Science Education) and also aim at the Continuous Professional Development (CPD) for teachers. The backbone supporting all educational activities is the enormous expertise of ESA in the various aspects of Space Science and Technology, like Earth Observation, Space Science (including Astronomy & Astrophysics), Human Spaceflight and Space Technology (launchers, navigation, telecommunications etc.). All educational activities, which are coordinated by the ESA Education Office, are designed for specific age groups, strive to keep the educational community informed and to provide inspirational materials for teachers and students. They can be subdivided in categories, like: Hands-on-projects, opportunities for students, support to teachers, international cooperation activities and outreach initiatives. In addition, ESA develops a variety of educational materials to support teachers in the classroom, both in classic form or on-line, through a network of dedicated websites.

A Web Based Approach to Integrate Space Culture and Education  

NASA Astrophysics Data System (ADS)

Our intention is to dedicate a large section of our web site to space education. As the national User Support and Operation Center (USOC) for the International Space Station, MARS Center is also willing to provide material, such as videos and data, for educational purposes. In order to base our initiative on authoritative precedents, our first step has been a comparative analysis between different space agency education web sites, such as ESA and NASA. As is well known, Internet is a powerful reality, capable of connecting people all over the world and rendering public a huge amount of information. The first problem, then, is to organize this information, in order to use the web as an efficient education tool. That is why studies such as User Modeling (UM), Human Computer Interaction (HCI) and Semantic Web have become more important in Information Technology and Science. Traditional search engines are unable to provide an optimal retrieval of contents really searched for by users. Semantic Web is a valid alternative: according to its theories, web information should be represented using metadata language. Users should be able and enabled to successfully search, obtain and study new information from web. Forging knowledge in an intelligent manner, preventing users from making errors, and making this formidable quantity of information easily available have also been the starting points for HCI methodologies for defining Adaptable Interfaces. Here the information is divided into different sets, on the basis of the intended user profile, in order to prevent users from getting lost. Realized as an adaptable interface, an education web site can help users to effectively retrieve the information necessary for their scopes (teaching for a teacher and learning for a student). For students it's a great advantage to use interfaces designed on the basis of their age and scholastic level. Indeed, an adaptable interface is intended not just for students, but also for teachers, who can use it to prepare their lessons, retrieve information and organize the didactic material in order to support their lessons. We think it important to use a user centered "psychology" based on UM: we have to know the needs and expectations of the students. Our intent is to use usability tests not just to prove the site effectiveness and clearness, but also to investigate aesthetical preferences of children and young people. Physics, mathematics, chemistry are just some of the difficult learning fields connected with space technologies. Space culture is a potentially never-ending field, and our scope will be to lead students by hand in this universe of knowledge. This paper will present MARS activities in the framework of the above methodologies aimed at implementing a web based approach to integrate space culture and education. The activities are already in progress and some results will be presented in the final paper.

The Hubble Space Telescope Education and Public Outreach Program  

NASA Astrophysics Data System (ADS)

The Hubble Space Telescope has conducted a long-standing and vigorous program in education and public outreach. This program uses a variety of methods to reach a broad spectrum of audiences. Education products are developed in a team environment that partners educators, curriculum experts, scientists, and production experts, such as graphic artists, Web designers, programmers, and education evaluators. A popular Web site is maintained, and has been substantially augmented in the past year. The Amazing Space program consists of a suite of online, interactive modules for use in the kindergarten through 12th grade classroom. The program is rooted in the national education standards and benefits from a robust evaluation process. The HST images and data are used to engage students in learning basic science and mathematics concepts. The activity/lessons include extensive, online assistance for educators, so that they can be readily used in the classroom. Hardcopy products such as posters, lithographs, teacher guides, and trading cards are generally tied to online products, to provide multiple entries to the material. We also provide training for teachers in the use of our products, as appropriate. Informal science education is supported by providing services to museums, planetariums, libraries and related institutions. The very popular ViewSpace, a computer-based video service is being used by many informal science facilities. In addition, HST has supported the creation of both permanent and traveling exhibits about HST. The Space Telescope Science Institute operates the Hubble Space Telescope for NASA.

Space architecture education as a part of aerospace engineering curriculum  

NASA Astrophysics Data System (ADS)

Education is particularly important for new fields. In the case of space architecture, there are two core needs: educating the aerospace community about the architect's function and activity and design process within the enterprise; educating space architects and associated specialists about constraints, conditions, and priorities unique to human space systems. These needs can be addressed, respectively, by two key educational tools for the 21st century: introducing the space architecture discipline into the space system engineering curricula; developing space architecture as a distinct, complete training curriculum. New generations of professionals with a space architecture background can help shift professional focus from just engineering-driven transportation systems and "sortie" missions to permanent offworld human presence by offering their inherently integrative design approach to all types of space structures and facilities. Although architectural and engineering approaches share some similarities in solving problems, they also have significant differences. Architectural training teaches young professionals to operate at all scales from the "overall picture" down to the smallest details to provide directive intention - not just analysis - to design opportunities, to address the relationship between human behavior and the built environment, and to interact with many diverse fields and disciplines throughout the project lifecycle.

Modeling volatility using state space models.  

PubMed

In time series problems, noise can be divided into two categories: dynamic noise which drives the process, and observational noise which is added in the measurement process, but does not influence future values of the system. In this framework, we show that empirical volatilities (the squared relative returns of prices) exhibit a significant amount of observational noise. To model and predict their time evolution adequately, we estimate state space models that explicitly include observational noise. We obtain relaxation times for shocks in the logarithm of volatility ranging from three weeks (for foreign exchange) to three to five months (for stock indices). In most cases, a two-dimensional hidden state is required to yield residuals that are consistent with white noise. We compare these results with ordinary autoregressive models (without a hidden state) and find that autoregressive models underestimate the relaxation times by about two orders of magnitude since they do not distinguish between observational and dynamic noise. This new interpretation of the dynamics of volatility in terms of relaxators in a state space model carries over to stochastic volatility models and to GARCH models, and is useful for several problems in finance, including risk management and the pricing of derivative securities. Data sets used: Olsen & Associates high frequency DEM/USD foreign exchange rates (8 years). Nikkei 225 index (40 years). Dow Jones Industrial Average (25 years). PMID:9730016

The situation of space education in the unified Germany  

NASA Astrophysics Data System (ADS)

Because of the unique situation of the unified Germany it is worth discussing the state of the art and the future aspects of space education in this country. Two different social and educational systems of the F.R.G. (Federal Republic of Germany) and the G.D.R. (German Democratic Republic) have to be synchronized. The increase of the population by the unification affected the space science related people. So the majorities change. At the moment the severe unemployment situation in eastern Germany hides this fact. But we have to be prepared for this in years to come. The different relation to the space science programs of the U.S.A. and Russia for the German scientist gives a chance for more international understanding and cooperation. This becomes a subject of educational approach to the international cooperation problem. The start of DARA (the German national space administration) in 1989 accompanied by dramatic concentration of space knowledge in DASA (the cooperation of the German national space industry) in the late eighties, shows that Germany has begun to concentrate its capabilities. On such a background, space education for the majority of the population becomes understandable and desirable. European commercial unification on an open market at the beginning of 1993 helps to concentrate the Germans on their historical part and task in the European market. Therefore, many solutions to establish effective space education becomes visible which were hidden behind walls of emotions and prejudices in the past. So the forecast for space education in Germany for the nineties has never been better. The only remaining problem—funding—has to be solved by unconventional ways, e.g. a foundation by the industry as in other countries.

Technological innovations and publications related to space science education  

NASA Astrophysics Data System (ADS)

As NASA Administrator Dan Goldin has noted, children are especially interested in three things: ghosts, dinosaurs, and space. We need to capitalize on the interest in space to develop and encourage a continuing understanding and curiosity about space-related issues from the grade school level through adulthood. Unfortunately, because astronomy is usually only offered in college as an introductory-level elective or as a specialized area of graduate study, most pre-college educators are uncomfortable teaching space sciences in the classroom. Additionally, the particularly dynamic nature of the field leaves educators with materials that are out-of-date and inadequate. In the framework of the new educational pedagogy focusing on hands-on activities, this paper presents a discussion of technologically innovative resources for the space science classroom (primarily at the high school level) which utilize hands-on activities for the students. The discussion will focus in five areas: major high-tech programs (which require specialized equipment in the schools), national and local workshops available to educators, hands-on activities commercially available, educational astronomical resources, and examples of hands-on activities developed and expanded upon by teachers and astronomers attending an educational workshop in Hawai'i from 1993-1995.

Strategies for Engaging NASA Space Scientists in K-12 > Education and Public Outreach  

NASA Astrophysics Data System (ADS)

The NASA Office of Space Science (OSS) has made a significant commitment to increase scientist participation in Education and Public Outreach (EPO), with a focus on providing tools and assistance for educators in K-12 education and for public informal education. The general goals are to use NASA scientific discoveries and mission results to contribute to the technical and scientific literacy of the nation, to inspire youth, and to achieve significant and sustained enhancement of K-12 education. The participation of AGU scientists in EPO activities is vital to achieving these goals. This participation by individual scientists is often voluntary, but it can be funded as supplements to research grants or directly by OSS missions, which are now required to spend a few percent of their total budget on EPO. Scientists can provide inspiring role models for students, be powerful partners with teachers, and can help assure the scientific accuracy of educational materials. Scientists can also contribute by working with their local and regional educational leadership to include modern Earth and space science results in school curricula and in local museum exhibits and programs. The importance of partnerships between scientists and local educators is one element of a new AGU position statement on effective Earth and space science education at the K-12 level. Examples will be presented of highly-effective EPO programs and the successful strategies for active participation of scientists, with emphasis on activities of interest to AGU scientists.

Teaching - orientation analysis in Space Science Education: The case of the Earth's Gravity Field  

NASA Astrophysics Data System (ADS)

This paper focuses on basic teaching-orientation questions concerning the use of secondary products of informatics in space science education. These questions can be classified as relevant to: (a) the educational model, (b) the educational approach, (c) the determination of additional teaching material according to student needs. The relevant analysis is followed by the example of an introductory course on the Earth's gravity field, a topic touching upon many different areas within Earth and Space sciences. The course is designed with a view to enhancing the cognitive skills of individuals studying in either a formal or an informal educational setting. A Java applet, specifically created to illustrate the energy level change between surfaces of equal potential on and around the Earth, provides the core upon which one may gradually build all the topics within this wide field of study, according to the needs of the educator and the specialisation of the course.

The use of urban space as an educational space for work on astronomy  

NASA Astrophysics Data System (ADS)

For several years we have been using urban space, with its squares, monuments, astronomical observatories and ancient ruins, as “educational space” in order to take school into large open-air spaces renowned for their history and cultural importance outside the premises of the school itself. So that this practice, whose validity and effectiveness for teaching will be demonstrated in what follows, may be more frequently experienced with students, we hold that it is necessary to put it forward to trainee and practising teachers in order that they are able to employ it with their students.

Modeling beams with elements in phase space  

SciTech Connect

Conventional particle codes represent beams as a collection of macroparticles. An alternative is to represent the beam as a collection of current carrying elements in phase space. While such a representation has limitations, it may be less noisy than a macroparticle model, and it may provide insights about the transport of space charge dominated beams which would otherwise be difficult to gain from macroparticle simulations. The phase space element model of a beam is described, and progress toward an implementation and difficulties with this implementation are discussed. A simulation of an axisymmetric beam using 1d elements in phase space is demonstrated.

Modelling of Tethered Space-Web Structures  

NASA Astrophysics Data System (ADS)

Large structures in space are an essential milestone in the path of many projects, from solar power collectors to space stations. In space, as on Earth, these large projects may be split up into more manageable sections, dividing the task into multiple replicable parts. Specially constructed spider robots could assemble these structures piece by piece over a membrane or space- web, giving a method for building a structure while on orbit. The modelling and applications of these space-webs are discussed, along with the derivation of the equations of motion of the structure. The presentation of some preliminary results from the solution of these equations will show that space-webs can take a variety of different forms, and give some guidelines for configuring the space-web system.

3D space analysis of dental models  

NASA Astrophysics Data System (ADS)

Space analysis is an important procedure by orthodontists to determine the amount of space available and required for teeth alignment during treatment planning. Traditional manual methods of space analysis are tedious and often inaccurate. Computer-based space analysis methods that work on 2D images have been reported. However, as the space problems in the dental arch exist in all three planes of space, a full 3D analysis of the problems is necessary. This paper describes a visualization and measurement system that analyses 3D images of dental plaster models. Algorithms were developed to determine dental arches. The system is able to record the depths of the Curve of Spee, and quantify space liabilities arising from a non-planar Curve of Spee, malalignment and overjet. Furthermore, the difference between total arch space available and the space required to arrange the teeth in ideal occlusion can be accurately computed. The system for 3D space analysis of the dental arch is an accurate, comprehensive, rapid and repeatable method of space analysis to facilitate proper orthodontic diagnosis and treatment planning.

Space Weather Around the World: An IHY Education Program  

NASA Astrophysics Data System (ADS)

Fifty years ago the International Geophysical Year organized a unique and unprecedented program of research that united 60,000 scientists from 66 nations to study global phenomena concerning the Earth and its space environment. In that same spirit, "Space Weather Around the World" is a program to coordinate and facilitate the involvement of NASA heliophysics missions and scientists to inspire and educate a world-wide audience about the International Heliophysical Year (IHY). We will use the popular Sun-Earth Day annual event framework sponsored by the Sun-Earth Connection Education Forum to promote IHY science and the spirit of international collaboration. The theme for the March 2007 Sun-Earth Day: "IHY: Living in the Atmosphere of the Sun" was selected a year ago in anticipation of the IHY celebration. These efforts will be expanded through a series of coordinated programs under the theme "Space Weather Around the World" for Sun-Earth Day 2008. We will produce a live broadcast from China of the total solar eclipse on August 1st 2008 as the central event, highlighting investigations associated with the eclipse by the international heliophysics community. Additional collaborative efforts will include: a Space Weather Media Maker web-tool to allow educators and scientists to create their own multi-media resource to enhance teaching and learning at all levels; Rock-n-Sol, a musical composition by children internationally inspired by space weather and incorporating sonifications of solar data; and Space Weather Action Centers for students to track a solar storm featuring podcasts of multi-cultural perspectives on IHY. The anticipated audience would be millions of people internationally The science and E/PO heliophysics community has an exciting story to tell about IHY, and we look forward to the opportunity to share it globally.

Space science education-an interdisciplinary and international programme  

NASA Astrophysics Data System (ADS)

The ISU's Master of Space Studies (MSS) programme is a new, unique and interdisciplinary postgraduate course of eleven months duration. It is designed for those who will lead and work in the international space programmes of the next century. It considers not only many aspects of the space sciences and their applications, but also most engineering, business, management, policy and law issues relevant to the activities of both space agencies and space industries. In the first term, fundamental issues are covered, and MSS participants from many countries around the world select some topics of their choice; within the sciences, attention is focused on basic physics, the space environment and life sciences. In the second and third terms, advanced subjects ranging from astronomy to planetary sciences, microgravity sciences, telecommunications and remote sensing of the Earth's surface and atmosphere are available. For two months in the second term, each participant carries out a project at an affiliate campus or an associated institution, and prepares a written report on this. Throughout the year, all participants play an active part in a team design project on a chosen theme; a substantial written report is prepared, and the results are also presented orally. Thus the aim of the MSS programme is to educate space generalists, yet generalists who are knowledgeable in all the relevant disciplines, including science.

Cross-cultural Education at the International Space University  

NASA Astrophysics Data System (ADS)

A typical nine-week summer session of the International Space University includes 100 graduate students and young professionals from as many as thirty countries. In addition to lectures and team projects covering a variety of space-related disciplines, the curriculum contains several modes of cross-cultural education. In role- playing workshops, students (asked to behave in accord with known cultural norms of various countries) engage in negotiations on problems such as the rescue and return of astronauts as mandated in international agreements and treaties. Culture shock that could derail such negotiations in actual practice is observed, and the participants come away with heightened sensitivity to cultural differences. This technique could be extended to other educational settings, such as the activities of the UN's Regional Centres in developing countries and the outreach efforts associated with the International Heliophysical Year.

Creating State-based Alliances to Support Earth and Space Science Education Reform  

NASA Astrophysics Data System (ADS)

Seven years after the publication of the National Science Education Standards and adoption of new state science education standards, Earth and space science remains outside the mainstream K-12 curriculum. Currently, less than ten percent of high school students in the United States of America take an Earth or space science course before graduation. This state of affairs is simply unacceptable. "All of us who live on this planet have the right and the obligation to understand Earth's unique history, its dynamic processes, its abundant resources, and its intriguing mysteries. As citizens of Earth, with the power to modify our climate and ecosystems, we also have a personal and collective responsibility to understand Earth so that we can make wise decisions about its and our future". As one step toward addressing this situation, we support the establishment of state-based alliances to promote Earth and space science education reform. "In many ways, states are the most vital locus of change in our nation's schools. State departments of education define curriculum frameworks, establish testing policies, support professional development and, in some cases, approve textbooks and materials for adoption". State alliance partners should include a broad spectrum of K-16 educators, scientists, policy makers, parents, and community leaders from academic institutions, businesses, museums, technology centers, and not-for profit organizations. The focus of these alliances should be on systemic and sustainable reform of K-16 Earth and space science education. Each state-based alliance should focus on specific educational needs within their state, but work together to share ideas, resources, and models for success. As we build these alliances we need to take a truly collaborative approach working with the other sciences, geography, and mathematics so that collectively we can improve the caliber and scope of science and mathematics education for all students.

Transforming community access to space science models  

NASA Astrophysics Data System (ADS)

Researching and forecasting the ever changing space environment (often referred to as space weather) and its influence on humans and their activities are model-intensive disciplines. This is true because the physical processes involved are complex, but, in contrast to terrestrial weather, the supporting observations are typically sparse. Models play a vital role in establishing a physically meaningful context for interpreting limited observations, testing theory, and producing both nowcasts and forecasts. For example, with accurate forecasting of hazardous space weather conditions, spacecraft operators can place sensitive systems in safe modes, and power utilities can protect critical network components from damage caused by large currents induced in transmission lines by geomagnetic storms.

Cosmos Education: Under African Skies and other Youth Initiatives for hands-on Education using Space  

NASA Astrophysics Data System (ADS)

'Under African Skies', a project of the charity organization Cosmos Education, undertook an excursion to sub-Saharan Africa to teach science and technology to children in primary and secondary schools. The role of science and technology for the purpose of development was emphasized, and the project directly addresses one of the recommendations of UNISPACE-III Vienna Declaration. Teaching primarily focused on astronomy and space science. Over 3500 primary and secondary school students in 5 different countries were reached. Although it is hard to quantify the impact of the teaching, the students' enthusiasm and questions demonstrated that they acquired knowledge and interest in science. In this talk we will summarize the objectives and achievements of the trip and future planned trips by Cosmos Education. We will also show coverage of the trip by the BBC program 'Final Frontier'. The youth perspective on education is outlined in the Global Space Education Curriculum, a project initiated at the UNISPACE III Space Generation Forum (SGF). This initiative is being further developed at the Space Generation Summit (SGS), an event at World Space Congress (WSC) that will unite international students and young professionals to develop a youth vision and strategy for the peaceful uses of space. SGS, endorsed by the United Nations, will take place from October 11-13th, during which the 200 delegates will discuss ongoing youth space activities, particularly those stemming from the UNISPACE-III/SGF and taken forward by the Space Generation Advisory Council. Delegates will address a variety of topics with the goal of devising new recommendations according to the theme, 'Accelerating Our Pace in Space'. The material presented here and in other technical sessions throughout WSC includes the results of these discussions.

Survey of cost models for space telescopes  

NASA Astrophysics Data System (ADS)

Parametric cost models are routinely used to plan missions, compare concepts, and justify technology investments. However, great care is required. There is a lot of confusion and wrong information for space telescopes. Cost estimating relationships based on primary mirror diameter vary by an order of magnitude. Cost estimating relationships based only on mass lack sufficient detail to support concept analysis and can lead to inaccurate conclusions by encouraging excessively complex and technologically immature solutions. Similarly, using ground-based models leads to incorrect conclusions. This work surveys current and historical published cost models for space telescopes while attempting to interpret them in a common logical framework to enable a systematic intercomparison.

Space time modeling of traffic flow  

NASA Astrophysics Data System (ADS)

This paper discusses the application of space-time autoregressive integrated moving average (STARIMA) methodology for representing traffic flow patterns. Traffic flow data are in the form of spatial time series and are collected at specific locations at constant intervals of time. Important spatial characteristics of the space-time process are incorporated in the STARIMA model through the use of weighting matrices estimated on the basis of the distances among the various locations where data are collected. These matrices distinguish the space-time approach from the vector autoregressive moving average (VARMA) methodology and enable the model builders to control the number of the parameters that have to be estimated. The proposed models can be used for short-term forecasting of space-time stationary traffic-flow processes and for assessing the impact of traffic-flow changes on other parts of the network. The three-stage iterative space-time model building procedure is illustrated using 7.5 min average traffic flow data for a set of 25 loop-detectors located at roads that direct to the centre of the city of Athens, Greece. Data for two months with different traffic-flow characteristics are modelled in order to determine the stability of the parameter estimation.

Rejoinder: Sifting through model space  

USGS Publications Warehouse

Observational data sets generated by complex processes are common in ecology. Traditionally these have been very challenging to analyze because of the limitations of available statistical tools. This seems to be changing, and these are exciting times to be involved with ecological statistics, not just because of the neo-Bayesian revival but also because of the proliferation of computationally intensive methods in general. It is now possible to fit much richer models to observational data than in the relatively recent past, which in turn has stimulated much interest in how to evaluate and compare such models. In such an immature, vibrant, and rapidly growing field, not everyone is going to agree on the best way to do things. This is reflected in the contrast of opinions offered by the discussants. Each offers a thoughtful and thought-provoking critique of our work that reflects the current thinking in a non-negligible segment of the ecological data analysis community. We want to thank them for their insights.

Understanding Models in Earth and Space Science (e-book)  

NSDL National Science Digital Library

It's a challenge educators at all grade levels face: How do you teach subjects your students can't see, touch, or hear? You do it with models--which have gained new importance since the National Science Education Standards specifically recommended using models as an organizing framework for teaching and understanding science. Whether your lessons concern molecules or Mars, Understanding Models in Earth and Space Science offers practical guidance. It's designed to help you understand the full range of models available to illustrate abstract concepts, demonstrate complex ideas, or teach about things students can't see. The book provides an in-depth look at specific kinds of models--what they are, how they can be designed, the best ways to use them, and possible shortcomings. Among the chapter topics are concrete models; mathematical models; similes, analogies, and metaphors; computer models; and inquiry and model building. Itself a model of good modeling, the book offers abundant examples (including drawing parallels between seemingly unrelated topics, such as how tornadoes are like vacuum cleaners) and plentiful background specific to Earth science teachers. Understanding Models is the result of a partnership between NSTA and the U.S. Environmental Protection Agency's Office of Pollution Prevention and Toxics.

Worms in space? A model biological dosimeter.  

PubMed

Although it is well known that radiation causes mutational damage, little is known about the biological effects of long-term exposure to radiation in space. Exposure to radiation can result in serious heritable defects in experimental animals, and in humans, susceptibility to cancer, radiation-sickness, and death at high dosages. It is possible to do ground controlled studies of different types of radiation on experimental animals and to physically measure radiation on the space station or on space probes. However, the actual biological affects of long-term exposure to the full range of space radiation have not been studied, and little information is available about the biological consequences of solar flares. Biological systems are not simply passive recording instruments. They respond differently under different conditions, and thus it is important to be able to collect data from a living animal. There are technical difficulties that restrict the placement of an experimental organism in a space environment for long periods of time, in a manner that allows for the recovery of genetic data. Use of the self-fertilizing hermaphroditic nematode, Caenorhabditis elegans offers potential for the design of a biological dosimeter. In this paper, we describe the advantages of this model system and review the literature of C. elegans in space. PMID:16038089

A 12 years brazilian space education activity experience  

NASA Astrophysics Data System (ADS)

A multidisciplinary group of students from the university and latter also from the high school was formed in 1988 with the objective to make them put in practice their knowledge in physics, chemistry and mathematics and engineering fields in experimental rocketry. The group was called "Grupo de Foguetes Experimentais", GFE. Since that time more than 150 students passed throw the group and now many of them are in the space arena. The benefits for students in a space hands-on project are many: More interest in their school subjects is gotten as they see an application for them; Interrelation attitudes are learned as space projects is a team activity; Responsibility is gained as each is responsible for a part of a critical mission project; Multidisciplinary and international experience is gotten as these are space project characteristics; Learn how to work in a high stress environment as use to be a project launch. This paper will cover the educational experiences gotten during these years and how some structured groups work. It is explained the objectives and how the group was formed. The group structure and the different phases that at each year the new team passes are described. It is shown the different activities that the group uses to do from scientific seminars, scientific club and international meetings to technical tours and assistance to rocket activities in regional schools. It is also explained the group outreach activities as some launches were covered by the media in more then 6 articles in newspaper and 7 television news. In 1999 as formed an official group called NATA, Núcleo de Atividades Aerospaciais within the Universidade Estadual de Londrina, UEL, by some GFE members and teachers from university. It is explained the first group project results.

The organizations for space education and outreach programs in the Republic of Korea  

NASA Astrophysics Data System (ADS)

Korea has a short history in space development compared to neighboring countries like Japan, China, India and Russia. During the past 20 years, Korea has focused on developing satellite and rocket space technology under the national space development plan. KOMPSAT-1 and 2, and KSLV-1 are the results of the selection and concentration policy of the Korean government. Due to the arduous mission of developing hardware oriented space technology, the topic of space education and outreach for the general public has not received much in the national space program. But recently, the Korean government has begun planning a space science outreach program in the detailed action plan of the mid-long term national space development plan. This paper introduces and analyzes the organizations performing space education and outreach programs for primary and secondary schools in the Republic of Korea. “Young Astronaut Korea (YAK)” is one such program. This is a non-profit organization established to provide space education for students in 1989 when Korea just started its space development program. “YAK” is a unique group in Korea for space education and outreach activities because it is organized by branches at each school in the nation and it is much like the Boy Scout and Girl Scout programs. Space Science Museum and National Youth Space Center (NYSC), which are located near NARO space center in the southernmost part of the Korean peninsula are other examples of space education and outreach programs. NARO space center, which is the only launch site in Korea became the center of public interest by showing the KSLV-1 launch in 2009 and will be expected to play a key role for the space education of students in the Republic of Korea. The NYSC will perform many mission oriented space education programs for students as Space Camp in the USA does. This paper introduces the status of the space education and outreach programs of each organization and presents the future direction of space education and outreach for the Korean public and students. If these three organizations cooperate with each other and develop systematic programs of space education and outreach for the people, they will prepare a base for growth and progress in future space science and technology in Korea.

Nonlinear sigma model in de Sitter space  

NASA Astrophysics Data System (ADS)

We investigate infrared dynamics of the nonlinear sigma model in de Sitter space. In the presence of minimally coupled massless scalar fields, the de Sitter symmetry is dynamically broken and physical constants become time dependent. We find that the effective coupling constant of the nonlinear sigma model becomes time dependent. The power counting arguments of the infrared logarithms indicate that the effective cosmological constant also acquires time dependence. We find that such infrared logarithms cancel out in a perturbative investigation up to the two loop level. We further demonstrate a nonperturbative nonrenormalization of the cosmological constant in the large N limit of the nonlinear sigma model.

ISUSAT: a satellite and space education programme for the International Space University  

NASA Astrophysics Data System (ADS)

Design, construction and implementation of a small satellite system has both educational and operational merit. At the International Space University (ISU) plans for the design of a small satellite have been laid. Each year some 130 students from 30 countries meet during the summer at ISU for an intense lecture and project programme covering all fields of space knowledge. The ISUSAT programme will form part of the future ISU summer projects to result in both a satellite payload, bus and a number of ground stations functioning as terrestrial nodes for amateur communications and science experiments. The first stage of ISUSAT has begun with the designing and building of small low cost UHF/VHF ground stations. This exercise approaches the spacecraft design from the user or ground segment end. In this way selection and design of payload and linking the space gateway to existing terrestrial networks, is better understood and facilitated. During the summer session at ISU92 Kitakyusku, Japan, ground station construction began.

Space science education in Egypt and the 2006 solar eclipse  

NASA Astrophysics Data System (ADS)

The space science research has been started in Egypt since 1910 by measuring the solar constant as indication of solar radiation at Helwan Observatory. The solar sunspot studies and its influence on the Nile flooding was erected and operated at Helwan as a first solar station in Egypt during 1957. Zeiss-Coude' refractor was installed in 1964. Astronomy and space science educations started in Egypt at the university level since 1936 at Department of Astronomy and Meteorology of Cairo University. Undergraduate and graduate education in Egypt will be discussed in this work. The total solar eclipse observations on 25th February, 1952 in Khartoum have been done by on Egyptian-French group by using the Worthington Camera. Several international groups observed the total solar eclipse on 29 March 2006, in El-Saloum (Egypt). A coordinated effort partly undertaken in the frame of the French-Egyptian scientific cooperation permitted joined simultaneous eclipse observations of the solar corona. Several Ground base instrumental set-up has been prepared. Spaceborne quasi-simultaneous EIT and Lasco observations of SoHO have been used as well as TRACE observations in Lyman-alpha of HI. W-L images taken with and without a radial filter are processed to show the magnetic structure of the corona. Polarization analysis is performed to study the F-corona in the outer corona. Several filters have been obtained to show the distribution of the emission measures of the inner and middle corona. Spectra were obtained over several emission lines.

Joint spacing criterion for equivalent continuum model  

SciTech Connect

Currently, the Yucca Mountain Site Characterization Project is investigating the feasibility of the disposal of high-level radioactive waste in the unsaturated Topopah Spring formation. The Topopah Spring formation is a heavily fractured, predominantly vertically jointed, welded tuff, and the potential disposal area is cut by the Ghost Dance fault and bounded by several other faults structures. The joints in the tuff and the faults may have an impact on the emplacement drift or borehole stability, as well as on the movement of fluids through the rock mass. The design of the repository drifts and layout, the waste emplacement scheme, and the thermomechanical performance of the rock mass will be analyzed using various numerical models. These models may be based on different assumptions regarding the representation of the fracture behavior under given applied stresses, and will range from discrete models where individual mechanically active fractures are treated distinctly, to continuum models where the joint behavior is smeared over a representative volume. There is always the question of applicability of a model with respect to a given material domain to be analyzed. For the mechanical analysis of the rock mass response around a repository drift, the applicability of an equivalent continuum model is dependent on the joint spacing in the rock mass. Considering the joint spacings that may be encountered at the potential repository site, a ratio of joint spacing to the planned drift diameter may be adopted as a criterion for evaluating the applicability of the Compliant Joint Model (CJM) in the Yucca Mountain Site Characterization Project. In this paper, this criterion is established by reviewing basic continuum concepts and numerical approximation implications used to build the CJM and by examining rock mass conditions that may be encountered at the potential Yucca Mountain repository site.

The resulting low-energy theory is old-minimal supergravity coupled to tensor multiplet. The dilaton is part of the compensator multiplet.

Scientific Benefits of Space Science Models Archiving at Community Coordinated Modeling Center  

NASA Astrophysics Data System (ADS)

The Community Coordinated Modeling Center (CCMC) hosts a set of state-of-the-art space science models ranging from the solar atmosphere to the Earth's upper atmosphere. CCMC provides a web-based Run-on-Request system, by which the interested scientist can request simulations for a broad range of space science problems. To allow the models to be driven by data relevant to particular events CCMC developed a tool that automatically downloads data from data archives and transform them to required formats. CCMC also provides a tailored web-based visualization interface for the model output, as well as the capability to download the simulation output in portable format. CCMC offers a variety of visualization and output analysis tools to aid scientists in interpretation of simulation results. During eight years since the Run-on-request system became available the CCMC archived the results of almost 3000 runs that are covering significant space weather events and time intervals of interest identified by the community. The simulation results archived at CCMC also include a library of general purpose runs with modeled conditions that are used for education and research. Archiving results of simulations performed in support of several Modeling Challenges helps to evaluate the progress in space weather modeling over time. We will highlight the scientific benefits of CCMC space science model archive and discuss plans for further development of advanced methods to interact with simulation results.

How do cost models help in making economic decisions about space transportation vehicles? To what extent do cost models illuminate the cost impact of decisions due to management, technical, engineering and manufacturing, and cultural factors? What types of cost explanatory variables are used and what are their impacts? We shall first identify cost drivers across several space cost models: PRICE-H, SEER-H, TRANSCOST, and NAFCOM, and then classify them by using a management cost reduction matrix. Second, we shall review cost explanatory variables for vehicle structure, engine system, and process and technical parameters. Third, we will present a simple baseline, consisting of a launch vehicle structure and engine and discuss methodology to develop the inter-model comparison of cost drivers. Fourth, we will present the economic properties of the cost models which include economies of size, schedule, learning curve and process improvement, and economic externalities. The concluding section lists the most important cost drivers and comments on each cost model's strengths.

Scale space methods for climate model analysis  

NASA Astrophysics Data System (ADS)

In this paper, we introduce methods for evaluating climate model performance across spatial scales. These techniques are based on the "scale space" framework widely used in the image processing and computer vision communities. We discuss why the diffusion equation on the sphere provides a particularly attractive means of smoothing two-dimensional maps of global climate data. We establish that no structure is introduced into a map as an artifact of the smoothing procedure. This allows for the comparison of models and observations at multiple scales. As a test case for these methods, we compare the ability of high- and low-resolution versions of the Community Climate System Model (CCSM) to simulate the seasonal climatologies of surface air temperature (TAS), sea level pressure (PSL), and total precipitation rate (PR). For TAS, we find that the high-resolution model is better able to capture the boreal summer (JJA) climatological pattern at fine scales, although there is no such improvement in winter (DJF). We find the performances of the high- and low-resolution models to be similarly capable of capturing the summertime sea level pressure climatology at all scales. However, the high-resolution model PSL climatology is degraded for DJF, especially at larger scales. For both JJA and DJF precipitation climatologies, we find larger precipitation errors in the high-resolution model at the finest scales; however, performance at larger scales is improved.

A study group has been formed in order to have a better understanding of this old machine and seek possible improvements. The work includes lattice modeling, numerical simulations, bench measurements and beam studies. Based on newly obtained information, it has been found that the machine acceptance is severely compromised by the orbit bump and dogleg magnets. This, accompanied by emittance dilution from space charge at injection, is a major cause of the large beam loss at the early stage of the cycle. Measures to tackle this problem are being pursued.

Space Education Strategy Using Data Obtained by Lunar and Planetary Missions  

NASA Astrophysics Data System (ADS)

Japanese two lunar and planetary missions, Kaguya (SELENE) and Hayabusa (MUSES-C) are returning vast amount of result to the Earth, and these data are planned to open to the public via the Internet. These are considered useful not only for scientists and engineers but also for the educators and students as a “real textbook”. In space education, we can use several methods to facilitate students' interest. Here we describe some of our examples to promote space education. One is the event accompanying with the major conferences, and second is the video program describing the Hayabusa mission with very unique viewpoint, and the third is the website carefully designed for children. However, the application of mission results to the space education has some points which should be specific to these missions. This paper describes our current attempt of these application and future prospects for the promotion of space education.

A space radiation test model study  

NASA Astrophysics Data System (ADS)

Dynamic models of the energetic populations in the outer radiation belts are being developed to better understand the extreme variations of particle flux in response to magnetospheric and solar activity. The study utilizes the SCATHA SC3 high energy electron data, covering energies from 47 keV to 5 MeV with fine pitch angle measurements (3 deg field of view) over the L-shell range of 5.3 to 8.7. Butter-fly distributions in the dusk sector signify particle losses due to L shell splitting of the particle drift orbits and the subsequent scattering of the particles from the orbits by the magnetopause. To model the temporal variations and diffusion procsses of the particle populations, the data have been organized into phase space distributions, binned according to altitude (L shell), energy, pitch angle, and time. These distributions can then be mapped to the equator and plotted for fixed first and second adiabatic invariants of the inherent particle motion. A new and efficient method for calculating the third adiabatic invariant using a line integral of the relevant magnetic potential a t the particle mirror points has been developed and is undergoing testing. This method will provide a useful means of displaying the radial diffusion signatures of the outer radiation belts during the more active periods when the L shell parameter is not a good concept due to severe drift-shell splitting. The first phase of fitting the energetic electron phase-space distributions with a combined radial and pitch-angle diffusion formulation is underway.

Improving the physics models in the Space Weather Modeling Framework  

NASA Astrophysics Data System (ADS)

The success of physics based space weather forecasting depends on several factors: we need sufficient amount and quality of timely observational data, we have to understand the physics of the Sun-Earth system well enough, we need sophisticated computational models, and the models have to run faster than real time on the available computational resources. This presentation will focus on a single ingredient, the recent improvements of the mathematical and numerical models in the Space Weather Modeling Framework. We have developed a new physics based CME initiation code using flux emergence from the convection zone solving the equations of radiative magnetohydrodynamics (MHD). Our new lower corona and solar corona models use electron heat conduction, Alfven wave heating, and boundary conditions based on solar tomography. We can obtain a physically consistent solar wind model from the surface of the Sun all the way to the L1 point without artificially changing the polytropic index. The global magnetosphere model can now solve the multi-ion MHD equations and take into account the oxygen outflow from the polar wind model. We have also added the options of solving for Hall MHD and anisotropic pressure. Several new inner magnetosphere models have been added to the framework: CRCM, HEIDI and RAM-SCB. These new models resolve the pitch angle distribution of the trapped particles. The upper atmosphere model GITM has been improved by including a self-consistent equatorial electrodynamics and the effects of solar flares. This presentation will very briefly describe the developments and highlight some results obtained with the improved and new models.

NASA Lunar Sample Education Disk Program - Space Rocks for Classrooms, Museums, Science Centers and Libraries  

NASA Astrophysics Data System (ADS)

NASA is eager for students and the public to experience lunar Apollo rocks and regolith soils first hand. Lunar samples embedded in plastic are available for educators to use in their classrooms, museums, science centers, and public libraries for education activities and display. The sample education disks are valuable tools for engaging students in the exploration of the Solar System. Scientific research conducted on the Apollo rocks has revealed the early history of our Earth-Moon system. The rocks help educators make the connections to this ancient history of our planet as well as connections to the basic lunar surface processes - impact and volcanism. With these samples educators in museums, science centers, libraries, and classrooms can help students and the public understand the key questions pursued by missions to Moon. The Office of the Curator at Johnson Space Center is in the process of reorganizing and renewing the Lunar and Meteorite Sample Education Disk Program to increase reach, security and accountability. The new program expands the reach of these exciting extraterrestrial rocks through increased access to training and educator borrowing. One of the expanded opportunities is that trained certified educators from science centers, museums, and libraries may now borrow the extraterrestrial rock samples. Previously the loan program was only open to classroom educators so the expansion will increase the public access to the samples and allow educators to make the critical connections of the rocks to the exciting exploration missions taking place in our solar system. Each Lunar Disk contains three lunar rocks and three regolith soils embedded in Lucite. The anorthosite sample is a part of the magma ocean formed on the surface of Moon in the early melting period, the basalt is part of the extensive lunar mare lava flows, and the breccias sample is an important example of the violent impact history of the Moon. The disks also include two regolith soils and orange glass from a pyroclastic deposit. The loan program also includes Meteorite Disks containing six meteorites that will help educators share the early history of the solar system with students and the public. Educators may borrow either lunar or meteorite disks through Johnson Space Center Curatorial Office. In trainings provided by the NASA Aerospace Education Services Program specialists, educators certified to borrow the disk learn about education resources, the proper use of the samples, and the special security for care and shipping of the disks. The Lunar and Meteorite Sample Education Disk Program is set up to bridge to new education programs that will carry NASA exploration to more people. Getting Space Rocks out to the public and connecting the public to the current space exploration missions is the focus the NASA disk loan program.

An Evolutionary Model for Space Solar Power  

NASA Astrophysics Data System (ADS)

The primary difficulties with the dream of Space Solar Power (SSP) for Earth, are the extreme launch costs of solar power satellites to Geosynchronous Earth Orbit (GEO), and the absence of an evolutionary path to SSP. This makes the cost-to-first-power unacceptably high. This paper presents a 3-stage approach to SSP, and lay out the problems and opportunities. The key idea is to use space assets initially for global transmission and distribution, rather than generation, establish the infrastructure, and then add space-based power generation to a revenue-generating power grid. In the first stage, a Space Power Grid is established with satellites 1,200 km above Earth, distributing earth-generated beamed microwaves to other satellites and ground receivers. This boosts the earth-based alternative power industry (wind and solar-thermal) by providing transmission between any points on earth, and accommodating fluctuations in demand and supply. It also satisfies strategic needs for emergency power delivery. In Stage 2, direct power conversion technology will augment the existing space power grid with space-generated solar power. In Stage 3, large ultralight GEO reflectors will beam light to the direct-conversion collectors, and multiply the power through the grid. The need to put expensive, heavy solar arrays in high orbit is avoided, along with the objections to atmospheric transmission of visible light. The system would gain significantly from the development of low-mass, high-efficiency conversion equipment for direct conversion of broadband solar energy to beamed microwaves.

In a planetarium, the visitor is sitting on Earth and looking into an imaginary space. The Planetarium Inversum is the opposite: visitors are sitting in a space station, looking down on Mother Earth. It is a scientifically-based information show with visitors involvement, its elements being partially virtual (Earth in space has to be projected with highest possible resolution) but also containing real structures, such as the visitors' Earth observatory with adjacent biological systems (plant cultures and other ecological life support components). Its main message concerns the limits and the vulnerability of our home planet, its uniqueness, beauty and above all, its irreplaceableness: Earth does not have an emergency exit. The Earth observatory is part of a ring shaped, rotating space station of the type designed by Wernher von Braun decades ago. Visitors are told that gravity is being substituted by centrifugal force. Both types of life support systems are being demonstrated--self regenerative life based ones and technical ones as a backup (solar electric splitting of water and chemical absorption of respiratory CO2).

Young engineers and scientists - a mentorship program emphasizing space education  

NASA Astrophysics Data System (ADS)

Young Engineers and Scientists (YES) is a community partnership between Southwest Research Institute (SwRI), and local high schools in San Antonio, Texas (USA) during the past 16 years. The YES program provides talented high school juniors and seniors a bridge between classroom instruction and real world, research experiences in physical sciences (including space science) and engineering. The first component of YES is an intensive three-week summer workshop held at SwRI where students experience the research environment first-hand; develop skills and acquire tools for solving scientific problems, attend mini-courses and seminars on electronics, computers and the Internet, careers, science ethics, and other topics; and select individual research projects to be completed during the academic year. Afterwards, students complete individual research projects under the guidance of their mentors during the academic year and earn honors credit. At the end of the school year, students publicly present and display their work, acknowledging their accomplishments and spreading career awareness to other students and teachers. During these years, YES has developed a website for topics in space science from the perspective of high school students, including NASA's Magnetospheric Multiscale Mission (MMS) (http://yesserver.space.swri.edu). High school science teachers participate in the workshop and develop space-related lessons for classroom presentation in the academic year. Student evaluations indicate the effectiveness of YES on their academic preparation and choice of college majors. Over the past 16 years, all YES graduates have entered college, several have worked for SwRI, one business has started, and three scientific publications have resulted. Acknowledgements. We acknowledge funding and support from the NASA MMS Mission, Texas Space Grant Consortium, Northside Independent School District, SwRI, and several local charitable foundations.

The space of phylogenetic mixtures for equivariant models  

PubMed Central

Background The selection of an evolutionary model to best fit given molecular data is usually a heuristic choice. In his seminal book, J. Felsenstein suggested that certain linear equations satisfied by the expected probabilities of patterns observed at the leaves of a phylogenetic tree could be used for model selection. It remained an open question, however, whether these equations were sufficient to fully characterize the evolutionary model under consideration. Results Here we prove that, for most equivariant models of evolution, the space of distributions satisfying these linear equations coincides with the space of distributions arising from mixtures of trees. In other words, we prove that the evolution of an observed multiple sequence alignment can be modeled by a mixture of phylogenetic trees under an equivariant evolutionary model if and only if the distribution of patterns at its columns satisfies the linear equations mentioned above. Moreover, we provide a set of linearly independent equations defining this space of phylogenetic mixtures for each equivariant model and for any number of taxa. Lastly, we use these results to perform a study of identifiability of phylogenetic mixtures. Conclusions The space of phylogenetic mixtures under equivariant models is a linear space that fully characterizes the evolutionary model. We provide an explicit algorithm to obtain the equations defining these spaces for a number of models and taxa. Its implementation has proved to be a powerful tool for model selection.

Green space system design in Luoyang using Huff model  

NASA Astrophysics Data System (ADS)

Green space system, as part of the urban ecological environment and urban landscape, plays a significant role in the protection of biological diversity of the urban eco-systems. During the process of rapid modernization in China, it is evident that in order to satisfy the residents' needs of entertainment and communication effectively; there should be abundant types and adequate arrangement of green space. And at the same time a comprehensive and stable hierarchical structure of green space system ought to be established. Huff Model is widely used in facility location planning and service area segmentation in business geography, and has potentials in urban facility planning and design. This paper aims to evaluate, design and optimize the urban green space in Luoyang City, Henan Province, using GIS and Huff Model. Considering the existing location, size and shape of the green space supply, the spatial distribution of residence and the urban transportation systems, the attractiveness between residence and green space is estimated. The spatial pattern and service capability of the green space system are also evaluated critically. Based on the findings, the possible optimization design of the green space system in Luoyang is discussed innovatively. Huff model test shows that the design improves the overall spatial accessibility observably. The case study shows that GIS technology and Huff Model have great potential in urban green space evaluation, planning and design.

Development, validation and application of numerical space environment models  

NASA Astrophysics Data System (ADS)

Currently the majority of space-based assets are located inside the Earth's magnetosphere where they must endure the effects of the near-Earth space environment, i.e. space weather, which is driven by the supersonic flow of plasma from the Sun. Space weather refers to the day-to-day changes in the temperature, magnetic field and other parameters of the near-Earth space, similarly to ordinary weather which refers to changes in the atmosphere above ground level. Space weather can also cause adverse effects on the ground, for example, by inducing large direct currents in power transmission systems. The performance of computers has been growing exponentially for many decades and as a result the importance of numerical modeling in science has also increased rapidly. Numerical modeling is especially important in space plasma physics because there are no in-situ observations of space plasmas outside of the heliosphere and it is not feasible to study all aspects of space plasmas in a terrestrial laboratory. With the increasing number of computational cores in supercomputers, the parallel performance of numerical models on distributed memory hardware is also becoming crucial. This thesis consists of an introduction, four peer reviewed articles and describes the process of developing numerical space environment/weather models and the use of such models to study the near-Earth space. A complete model development chain is presented starting from initial planning and design to distributed memory parallelization and optimization, and finally testing, verification and validation of numerical models. A grid library that provides good parallel scalability on distributed memory hardware and several novel features, the distributed cartesian cell-refinable grid (DCCRG), is designed and developed. DCCRG is presently used in two numerical space weather models being developed at the Finnish Meteorological Institute. The first global magnetospheric test particle simulation based on the Vlasov description of plasma is carried out using the Vlasiator model. The test shows that the Vlasov equation for plasma in six-dimensionsional phase space is solved correctly b! y Vlasiator, that results are obtained beyond those of the magnetohydrodynamic (MHD) description of plasma and that global magnetospheric simulations using a hybrid-Vlasov model are feasible on current hardware. For the first time four global magnetospheric models using the MHD description of plasma (BATS-R-US, GUMICS, OpenGGCM, LFM) are run with identical solar wind input and the results compared to observations in the ionosphere and outer magnetosphere. Based on the results of the global magnetospheric MHD model GUMICS a hypothesis is formulated for a new mechanism of plasmoid formation in the Earth's magnetotail.

NASA Aquarius: Sea Surface Salinity from Space Education & Public Outreach  

NSDL National Science Digital Library

Aquarius is a focused satellite mission to measure global sea surface salinity. Launching in 2009, this mission will provide the first global map of sea surface salinity with unprecedented accuracy, resolution and coverage. The importance of salinity measurements in understanding coastal ocean processes is critical. Because of its dynamic range in the coastal oceans, salinity is a critical factor in understanding and predicting biological and physical processes and their interactions with the food Web, climate, and global water cycle. AquariusâÂÂs pioneering efforts to deliver the âÂÂmissing pieces of the climate puzzleâ will undoubtedly intrigue informal audiences via the activities and information contained in this Website. Moreover, climate and its influence on humankind is an integral part of K-16 formal education and common to national learning standards. The goal of the Education and Outreach component of Aquarius is to teach fundamental concepts about salinity variations and the role these changes play in controlling global ocean circulation and EarthâÂÂs climate. Education products will appear as modules addressing the missionâÂÂs goals and purpose, augment existing El Nino/La Nina materials with salinity based content, provide on-line interactive tools demonstrating environmental change through data sets and in situ time-series analysis, and engage students in activities designed to demonstrate salt-water interactions.

Fundamental State Space Time Series Models for JEPX Electricity Prices  

NASA Astrophysics Data System (ADS)

Time series models are popular in attempts to model and forecast price dynamics in various markets. In this paper, we have formulated two state space models and tested them for its applicability to power price modeling and forecasting using JEPX (Japan Electric Power eXchange) data. The state space models generally have a high degree of flexibility with its time-dependent state transition matrix and system equation configurations. Based on empirical data analysis and past literatures, we used calculation assumptions to a) extract stochastic trend component to capture non-stationarity, and b) detect structural changes underlying in the market. The stepwise calculation algorithm followed that of Kalman Filter. We then evaluated the two models' forecasting capabilities, in comparison with ordinary AR (autoregressive) and ARCH (autoregressive conditional heteroskedasticity) models. By choosing proper explanatory variables, the latter state space model yielded as good a forecasting capability as that of the AR and the ARCH models for a short forecasting horizon.

Modeling and validation of photometric characteristics of space targets oriented to space-based observation.  

PubMed

A modeling and validation method of photometric characteristics of the space target was presented in order to track and identify different satellites effectively. The background radiation characteristics models of the target were built based on blackbody radiation theory. The geometry characteristics of the target were illustrated by the surface equations based on its body coordinate system. The material characteristics of the target surface were described by a bidirectional reflectance distribution function model, which considers the character of surface Gauss statistics and microscale self-shadow and is obtained by measurement and modeling in advance. The contributing surfaces of the target to observation system were determined by coordinate transformation according to the relative position of the space-based target, the background radiation sources, and the observation platform. Then a mathematical model on photometric characteristics of the space target was built by summing reflection components of all the surfaces. Photometric characteristics simulation of the space-based target was achieved according to its given geometrical dimensions, physical parameters, and orbital parameters. Experimental validation was made based on the scale model of the satellite. The calculated results fit well with the measured results, which indicates the modeling method of photometric characteristics of the space target is correct. PMID:23142894

Validation of nuclear models used in space radiation shielding applications  

NASA Astrophysics Data System (ADS)

A program of verification and validation has been undertaken to assess the applicability of models to space radiation shielding applications and to track progress as these models are developed over time. In this work, simple validation metrics applicable to testing both model accuracy and consistency with experimental data are developed. The developed metrics treat experimental measurement uncertainty as an interval and are therefore applicable to cases in which epistemic uncertainty dominates the experimental data. To demonstrate the applicability of the metrics, nuclear physics models used by NASA for space radiation shielding applications are compared to an experimental database consisting of over 3600 experimental cross sections. A cumulative uncertainty metric is applied to the question of overall model accuracy, while a metric based on the median uncertainty is used to analyze the models from the perspective of model development by examining subsets of the model parameter space.

AFWA's Space Weather Modeling System: A Flexible Space Weather Forecast System  

NASA Astrophysics Data System (ADS)

A key requirement of models used for space weather forecasting is making them flexible enough to exploit new computational capabilities as technology advances. This flexibility occurs when models are made scalable and portable while maintaining their existing capabilities and accuracy. Scalability allows the models to run faster as more processors are added. Portability enables the models to run on a variety of computing platforms. This makes operational procurement decisions more flexible and cost-effective. The Battlespace Environments Institute (BEI) project supports the coupling of Earth system environment models, such as oceans and atmospheres together, under the Earth System Modeling Framework (ESMF). The project mandates scalability and portability of the coupled models to adapt readily to changing computational environments. The Space Weather Modeling System (SWMS) is a BEI model of solar-terrestrial space weather. The Hakamada-Akasofu-Fry version 2 (HAFv2) solar wind model and the Ionospheric Forecast Model (IFM) are the first two coupled components in SWMS. The HAFv2 model produces quantitative forecasts of solar wind parameters at Earth and elsewhere in the inner heliosphere. The IFM is the physics-based ionosphere model of Global Assimilation of Ionospheric Measurements (GAIM) data-assimilation model. IFM provides highly representative specifications of plasma conditions in the global ionosphere. Coupling these two models together in the SWMS enables multi-day forecasts of solar wind and ionospheric disturbances. SWMS is an example of a successful transition of research to operations that is flexible while maintaining accuracy. This capability is crucial to DoD because it provides their warfighters with the actionable space weather forecasts that they need to make operational decisions. We present the solar wind and ionospheric results of the SWMS model for the large solar storm of April 6-7, 2000 with comparisons to solar wind and ionospheric data.

A Simulation and Modeling Framework for Space Situational Awareness  

SciTech Connect

This paper describes the development and initial demonstration of a new, integrated modeling and simulation framework, encompassing the space situational awareness enterprise, for quantitatively assessing the benefit of specific sensor systems, technologies and data analysis techniques. The framework is based on a flexible, scalable architecture to enable efficient, physics-based simulation of the current SSA enterprise, and to accommodate future advancements in SSA systems. In particular, the code is designed to take advantage of massively parallel computer systems available, for example, at Lawrence Livermore National Laboratory. The details of the modeling and simulation framework are described, including hydrodynamic models of satellite intercept and debris generation, orbital propagation algorithms, radar cross section calculations, optical brightness calculations, generic radar system models, generic optical system models, specific Space Surveillance Network models, object detection algorithms, orbit determination algorithms, and visualization tools. The use of this integrated simulation and modeling framework on a specific scenario involving space debris is demonstrated.

NASA Aquarius: Sea Surface Salinity from Space Education Resources  

NSDL National Science Digital Library

The educational resources and activities on this Web site teach fundamental concepts about salinity variations and the role these changes play in controlling global ocean circulation and Earthâs climate. The modules augment existing El Nino/La Nina materials with salinity-based content, provide on-line interactive tools demonstrating environmental change through data sets and in situ time-series analysis, and engage students in activities designed to demonstrate salt-water interactions. Launched in June 2011, NASAâs Aquarius will provide the first global map of sea surface salinity with unprecedented accuracy, resolution and coverage. The importance of salinity measurements in understanding coastal ocean processes is critical as salinity is a key factor in understanding and predicting biological and physical processes and their interactions with the food web, climate, and global water cycle.

Comparing the Earth and its Neighbors: Examples from Earth and Space Science Education Projects  

NASA Astrophysics Data System (ADS)

There are a number of education and outreach projects that utilize planetary comparisons and solar system exploration to engage and educate formal and informal education audiences. For example, NASA's Solar System Exploration Education Forum has promoted an "Extreme Exploration" theme to tie current events in Solar System exploration to reviewed, standards-based classroom materials. Often, the "wow" factor of an event such as rovers on Mars, Venus transiting the sun, or a volcanic eruption on Earth serves a hook to motivate learners to invest the time to explore a topic. Students are then provided the opportunity to study concepts such as earth systems science, geologic processes, and climate change. This paper will highlight the efforts of earth and space science education and public outreach projects that use the theme of Earth and it's celestial neighbors to teach a variety of concepts. It will review a number of examples including: 1) an education module that utilizes prototype 3-D representations of Olympus Mons and the Hawaiian Islands as a tool to teach middle school students topographic concepts and geologic processes; 2) a unit on impact craters that also introduces earth-based remote sensing platforms; 3) an earth systems science museum exhibit that engages visitors to explore earth's atmosphere through comparison with Venus, Mercury and Mars; 4) a thematic unit on ice in the Solar System that delves into the properties of ice and water; and 5) a series of bridging activities designed to connect NASA earth and space science research for informal educators.

Creating innovative models of clinical nursing education.  

PubMed

Although nursing care has changed significantly over the past 30 years, methods to clinically train nursing students have not. The traditional model of clinical nursing education, where a faculty member oversees a group of six to eight students on an acute care unit for a 4- to 8-hour shift, provides a haphazard approach to learning. A need exists to find innovative ways to effectively train more nursing students to better prepare them for today's health care environment. Using a change framework, seven approaches to clinical nursing education were created through academic-practice partnerships. These approaches may increase the effectiveness and efficiency of the clinical nursing education system. PMID:23061436

Solar System atlas series on the Eötvös University, Budapest, Hungary: textbooks for space and planetary science education  

NASA Astrophysics Data System (ADS)

Planetary science education needs new forms of teaching. Our group have various initiatives of which a new atlas series about the studies of the Solar System materials, planetary surfaces and atmospheres, instrumental field works with robots (landers, rovers) and other beautiful field work analog studies. Such analog studies are both used in comparative planetology as scientific method and it also plays a key role in planetary science education. With such initiatives the whole system of the knowledge of terrestrial geology can be transformed to the conditions of other planetary worlds. We prepared both courses and their textbooks in Eötvös University in space science education and edited the following educational materials worked out by the members of our space science education and research group: (1): Planetary and Material Maps on: Lunar Rocks, Meteorites (2000); (2): Investigating Planetary Surfaces with the Experimental Space Probe Hunveyor Constructed on the Basis of Surveyor (2001); (3): Atlas of Planetary Bodies (2001); (4): Atlas of Planetary Atmospheres (2002); (5): Space Research and Geometry (2002); (6): Atlas of Micro Environments of Planetary Surfaces (2003); (7): Atlas of Rovers and Activities on Planetary Surfaces (2004); (8): Space Research and Chemistry (2005); (9): Planetary Analog Studies and Simulations: Materials, Terrains, Morphologies, Processes.

Logarithmically regularized inviscid models in borderline sobolev spaces  

NASA Astrophysics Data System (ADS)

Several inviscid models in hydrodynamics and geophysics such as the incompressible Euler vorticity equations, the surface quasi-geostrophic equation, and the Boussinesq equations are not known to have even local well-posedness in the corresponding borderline Sobolev spaces. Here Hs is referred to as a borderline Sobolev space if the L?-norm of the gradient of the velocity is not bounded by the Hs-norm of the solution but by the Hs~-norm for any s~>s. This paper establishes the local well-posedness of the logarithmically regularized counterparts of these inviscid models in the borderline Sobolev spaces.

A regressive storm model for extreme space weather  

NASA Astrophysics Data System (ADS)

Extreme space weather events, while rare, pose significant risk to society in the form of impacts on critical infrastructure such as power grids, and the disruption of high end technological systems such as satellites and precision navigation and timing systems. There has been an increased focus on modelling the effects of extreme space weather, as well as improving the ability of space weather forecast centres to identify, with sufficient lead time, solar activity with the potential to produce extreme events. This paper describes the development of a data-based model for predicting the occurrence of extreme space weather events from solar observation. The motivation for this work was to develop a tool to assist space weather forecasters in early identification of solar activity conditions with the potential to produce extreme space weather, and with sufficient lead time to notify relevant customer groups. Data-based modelling techniques were used to construct the model, and an extensive archive of solar observation data used to train, optimise and test the model. The optimisation of the base model aimed to eliminate false negatives (missed events) at the expense of a tolerable increase in false positives, under the assumption of an iterative improvement in forecast accuracy during progression of the solar disturbance, as subsequent data becomes available.

Modeling Technogenous Contamination of the Near-Earth Space  

NASA Astrophysics Data System (ADS)

In analyzing the technogenous contamination of the near-earth space (NES), the following issues have usually been considered: the estimation of the current level of NES contamination by objects of various size; the modeling of technogenous contamination evolution; the estimation of the probability of spacecraft collisions with space objects (SOs) of various size and the possible implications of hazardous collisions; the determination of characteristics of the flux of SOs of various size through the observation zones of ground-based and onboard means of measurement. The main difficulty in solving the aforementioned problems lies in the deficiency of the experimental data. The available measurement information was obtained in relatively small domains of multidimensional space: the altitude of a point-the latitude of a point-the SO size-the time. As a consequence, additional (a priori) information is invoked for determining the technogenous contamination characteristics at various points of the region mentioned above. The efficient use of experimental data and a priori information constitutes the basic problem of space debris modeling. This paper briefly outlines the data on three space debris (SD) models: ORDEM2000 (Orbital Debris Engineering Model, 2000), MASTER'99 (Meteoroid and Space Debris Terrestrial Environment Reference Model, 2000) and SDPA (Nazarenko, 1997, 2000; Nazarenko and Menshikov, 2001). The features of modeling techniques and the comparative characteristics of technogenous contamination are discussed in the paper.

In this paper a state-space formulation of the Muskingum-Cunge routing scheme is proposed. The state-space formulation utilizes real-time discharge measurements, accounts for modeling and observation errors, and allows real-time updating through a Kalman filter estimator. The new model is tested in two different geotechnical conditions to forecast six-hour discharge values in hypothetical channels. For realism, the geomorphologic characteristics of these case studies are determined on the basis of the regime theory. DWOPER, a field-tested numerical dynamic routing model, was used to provide ground truth data for the validation of the proposed model.

In this paper we look at how education and public outreach has been a major element in preparing the next generation of astronomers and in sharing with the public the excitement of discoveries we make when we explore the Universe. The National Aeronautics and Space Administration (NASA) has a clear set of goals and objectives related to education and public outreach. These goals follow directly from NASA's mission ``to inspire the next generation of explorers''. Making progress towards achieving these goals has become an important part of the broad justification for public support of space science.

Space charge algorithm for the multi ensemble model  

NASA Astrophysics Data System (ADS)

Derived from the Vlasov equation the Ensemble Model [A. Novokhatski, T. Weiland, PAC’99, New York, March 1999] has been elaborated for fast and efficient beam dynamics simulations. The Model represents a particle beam as a set of sub-beams or Ensembles, described by coordinates of the centroid and 6D phase space correlations. Whereas a space charge routine for the Single Ensemble Model (SEM) has been developed and tested [M. Krassilnkov, et al., ICAP 2000, Darmstadt, September 2000], implementation of the space charge algorithm for the Multi Ensemble Model (MEM) needs more efforts. A space charge model based on the Multi-Centered Gaussian Expansion (MCGE) [M. Krassilnikov, T. Weiland, ICAP’02, East Lansing, USA, October 2002] implies a smooth particle density distribution within an Ensemble but it requires rather large computational efforts. This paper presents another space charge algorithm, based on the analytical solution for the electromagnetic field of an ellipsoidal 3D charge distribution [M. Comunian, et al., Phys. Rev. Spec. Topics—Acc. Beams 4 (2001) 124201]. Using this algorithm one can calculate the space charge force and its gradient inside and outside the driving Ensemble. Features of the implementation and simplifying approximations are discussed in this paper.

A new ESA educational initiative: Euro Space Center class teachers in microgravity during parabolic flights  

NASA Astrophysics Data System (ADS)

Since 1984, the European Space Agency (ESA) has organized 30 aircraft parabolic flight campaigns in the frame of its Microgravity Programme to perform short duration scientific and technological experiments. On each campaign, ESA invites journalists to report to the general public on the research work conducted in weightlessness. A new initiative was launched in 2000 with the introduction of pedagogical experiments aiming at educating youngsters and the general public on weightlessness effects. In November 2000, four secondary school teachers detached to the Euro Space Center (ESC) participated in the 29th ESA campaign. The ESC in Belgium provides recreational and educational activities for the general public and organizes space classes targeted at primary and secondary school pupils. The four teachers performed simple experiments with gyroscopes, yo-yos, magnetic balls, pendulum and food to explain their different behaviour in weightlessness, to show characteristics and possibilities of the microgravity environment and the difficulties that astronauts encounter in their daily life in orbit.

The Space Experiment Module (SEM) concept is one of a number of education initiatives being pursued by the NASA Shuttle Small Payloads Project (SSPP) in an effort to increase educational access to space by means of Space Shuttle Small Payloads and associated activities. In the SEM concept, NASA will provide small containers ('modules') which can accommodate small zero-gravity experiments designed and constructed by students. A number, (nominally ten), of the modules will then be flown in an existing Get Away Special (GAS) carrier on the Shuttle for a flight of 5 to 10 days. In addition to the module container, the NASA carrier system will provide small amounts of electrical power and a computer system for controlling the operation of the experiments and recording experiment data. This paper describes the proposed SEM carrier system and program approach.

A Modeler's Perspective on Space Weather Forecasting (Invited)  

NASA Astrophysics Data System (ADS)

Space physics is moving into a new era where numerical models originally developed for answering science questions are used as the basis for making operational space weather forecasts. Answering this challenge requires developments on multiple fronts requiring collaborations across space physics disciplines and between the research and operations communities. Since space weather in geospace is driven by the solar wind conditions a natural solution to improving the forecast lead time is to couple geospace models to heliospheric models. The quality of these forecast is dependent upon the ability of the heliospheric models to accurately model IMF Bz. Another challenge presented by moving into the forecasting arena is preparing the models for real-time operation which includes both computational performance and data redundancy issues. Moving into operations also presents modelers with an opportunity to assess their models performance over calculation intervals unprecedented duration. A key collaboration in the transition of models to operation is the discussion between forecasters and developers on what forecast parameters can accurately be predicted by the current generation of numerical models. This collaboration naturally includes a discussion of the definition of the best metrics to be used in quantitatively assessing performance.

Opportunities for Space Science Education Using Current and Future Solar System Missions  

NASA Astrophysics Data System (ADS)

The Education and Public Outreach (E/PO) office in The Johns Hopkins University Applied Physics Laboratory (APL) Space Department strives to excite and inspire the next generation of explorers by creating interactive education experiences. Since 1959, APL engineers and scientists have designed, built, and launched 61 spacecraft and over 150 instruments involved in space science. With the vast array of current and future Solar System exploration missions available, endless opportunities exist for education programs to incorporate the real-world science of these missions. APL currently has numerous education and outreach programs tailored for K-12 formal and informal education, higher education, and general outreach communities. Current programs focus on Solar System exploration missions such as the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM), Miniature Radio Frequency (Mini-RF) Moon explorer, the Radiation Belt Storm Probes (RBSP), New Horizons mission to Pluto, and the Thermosphere Ionosphere Mesosphere Energetics and Dynamics (TIMED) Satellite, to name a few. Education and outreach programs focusing on K-12 formal education include visits to classrooms, summer programs for middle school students, and teacher workshops. APL hosts a Girl Power event and a STEM (Science, Technology, Engineering, and Mathematics) Day each year. Education and outreach specialists hold teacher workshops throughout the year to train educators in using NASA spacecraft science in their lesson plans. High school students from around the U.S. are able to engage in NASA spacecraft science directly by participating in the Mars Exploration Student Data Teams (MESDT) and the Student Principal Investigator Programs. An effort is also made to generate excitement for future missions by focusing on what mysteries will be solved. Higher education programs are used to recruit and train the next generation of scientists and engineers. The NASA/APL Summer Internship Program offers a unique glimpse into the Space Department’s “end-to-end” approach to mission design and execution. College students - both undergraduate and graduate - are recruited from around the U.S. to work with APL scientists and engineers who act as mentors to the students. Many students are put on summer projects that allow them to work with existing spacecraft systems, while others participate in projects that investigate the operational and science objectives of future planned spacecraft systems. In many cases these interns have returned to APL as full-time staff after graduation.

Modeling space charge in beams for heavy-ion fusion  

SciTech Connect

A new analytic model is presented which accurately estimates the radially averaged axial component of the space-charge field of an axisymmetric heavy-ion beam in a cylindrical beam pipe. The model recovers details of the field near the beam ends that are overlooked by simpler models, and the results compare well to exact solutions of Poisson`s equation. Field values are shown for several simple beam profiles and are compared with values obtained from simpler models.

Combustion space modeling of an aluminum furnace  

SciTech Connect

Secondary aluminum production (melting from aluminum ingots, scraps, etc.) offers significant energy savings and environmental benefits over primary aluminum production since the former consumes only five percent of the energy used in the latter process. The industry, however, faces technical challenges of further improving furnace melting efficiency and has been lacking tools that can help understand combustion process in detail and that will facilitate furnace design. Computational Fluid Dynamics (CFD) modeling has played increasingly important roles in evaluating industrial processes. As part of a larger program run by SECAT, a CFD model has been developed at Argonne National Laboratory to simulate fuel combustion, heat transfer (including thermal radiation), gaseous product flow (mainly CO2 and H2O), and production/transport of pollutant species/greenhouse gases in an aluminum furnace. Using this code, the surface heat fluxes are calculated and then transferred to a melt code. In order to have a high level of confidence in the computed results, the output from the code will be compared and validated against in-furnace measurements made in the Albany furnace. Once validated, the combustion code may be used to perform inexpensive parametric studies to investigate methods to optimize furnace performance. This paper will present results from the combustion modeling of an aluminum furnace as well as results from several parametric studies.

Observations and Modeling of Space Weather Impacts on the Earth  

NASA Astrophysics Data System (ADS)

``Space weather'' refers to conditions in the solar wind, magnetosphere, ionosphere, and upper atmosphere, that influence space-borne and ground-based technological systems and can endanger human space exploration. These effects are caused by variations in solar photon and particle radiation due to flares and coronal mass ejections, and changes in the solar/interplanetary magnetic field, that impact the magnetosphere and ionosphere. Space weather can initiate satellite failures, interfere with radio communications, cause navigation errors, disrupt electrical power distribution systems, and expose astronauts to dangerous levels of radiation. Mitigation requires both a better understanding of the space environment, and developing the ability to forecast conditions in space. The development of first-principles numerical models of the solar-terrestrial system gives us insight into the causes and nature of these phenomena, and holds the promise of ultimately being able to acquire a short-term predictive capability for some of them. This presentation will describe what we do and don't understand about the basic physics behind space weather, discuss some of its aspects and effects, and describe the latest observational and modeling efforts

Space-time formulation for finite element modeling of superconductors  

SciTech Connect

In this paper we present a new model for computing the current density and field distributions in superconductors by means of a periodic space-time formulation for finite elements (FE). By considering a space dimension as time, we can use a static model to solve a time dependent problem. This allows overcoming one of the major problems of FE modeling of superconductors: the length of simulations, even for relatively simple cases. We present our first results and compare them to those obtained with a 'standard' time-dependent method and with analytical solutions.

Amateur Radio on the International Space Station (ARISS) - the First Educational Outreach Program on ISS  

NASA Astrophysics Data System (ADS)

More than 40 missions over five years will be required to assemble the International Space Station in orbit. The astronauts and cosmonauts will work hard on these missions, but they plan to take some time off for educational activities with schools. Amateur Radio on the International Space Station represents the first Educational Outreach program that is flying on ISS. NASA's Division of Education is a major supporter and sponsor of this student outreach activity on the International Space Station. This meets NASA's educational mission objective: "To inspire the next generation of explorers...as only NASA can." As the International Space Station takes its place in the heavens, the amateur radio community is doing its part by helping to enrich the experience of those visiting and living on the station as well as the students on Earth. Through ARISS (Amateur Radio on the International Space Station), students on Earth have a once in a lifetime opportunity--to talk to the crew on-board ISS. Using amateur radio equipment set up in their classroom, students get a first-hand feel of what it is like to live and work in space. Each school gets a 10 minute question and answer interview with the on-orbit crew using a ground station located in their classroom or through a remote ground station. The ARISS opportunity has proven itself as a tremendous educational boon to teachers and students. Through ARISS, students learn about orbit dynamics, Doppler shift, radio communications, and working with the press. Since its first flight in 1983, amateur radio has flown on more than two-dozen space shuttle missions. Dozens of astronauts have used the predecessor program called SAREX (The Space Shuttle Amateur Radio Experiment) to talk to thousands of kids in school and to their families on Earth while they were in orbit. The primary goals of the ARISS program are fourfold: 1) educational outreach through crew contacts with schools, 2) random contacts with the amateur radio public, 3) scheduled contacts with the astronauts' friends and families and 4) ISS-based communications experimentation. By June 2002 over 65 schools have been selected from 10 countries for scheduled contacts with the orbiting ISS crews. Ten or more students at each school ask the astronauts questions. The nature of these contacts embodies the primary goal of the ARISS program -- to excite students' interest in science, technology and amateur radio. This paper will discuss the educational outreach capabilities of ARISS, some of the challenges that the ARISS-international team of volunteers overcame to bring this first educational activity on ISS into operation, and its plans for the future. It will also summarize the networking opportunities which expand each school contact, including local school media events, WorldCom support, MSNBC coverage, and internet access. In addition, educational outreach is extended through joint projects with IMAX-3D, Space Center Houston teacher training, and NASA internet activities.

Earth and Space Science in the new NRC "Conceptual Framework for New Science Education Standards"  

NASA Astrophysics Data System (ADS)

The National Academy of Sciences has begun the process of creating a new set of K-12 science education standards. At the start of 2011 the National Research Council will release its “Conceptual Framework for New Science Education Standards,” which provides a vision for creating new and improved set of guidelines for the teaching of science. The Earth & Space content was formulated by an Earth & Space Design Team, consisting of the authors of this abstract. The “Framework,” funded by the Carnegie Foundation of New York, places a greater emphasis on the practices of learning and on major cross-cutting themes that run through the four content areas: Earth and Space Science, Physical Science, Life Science, and Engineering and Technology. One aim of the framework is to inspire a set of science standards that are more fundamental, cross-connecting, and less fact-oriented. Compared to previous efforts, the Earth & Space Science component places greater emphasis on a systems approach to Earth Science, on the interrelationships between humans and Earth systems, and on the science surrounding and connected to climate change. The organization Achieve, Inc., has already begun to use this “Framework” for the creation of a set of national K-12 science education standards.

Bayesian latent structure models with space-time-dependent covariates  

PubMed Central

Spatial-temporal data requires flexible regression models which can model the dependence of responses on space- and time-dependent covariates. In this paper, we describe a semiparametric space-time model from a Bayesian perspective. Nonlinear time dependence of covariates and the interactions among the covariates are constructed by local linear and piecewise linear models, allowing for more flexible orientation and position of the covariate plane by using time-varying basis functions. Space-varying covariate linkage coefficients are also incorporated to allow for the variation of space structures across the geographical location. The formulation accommodates uncertainty in the number and locations of the piecewise basis functions to characterize the global effects, spatially structured and unstructured random effects in relation to covariates. The proposed approach relies on variable selection-type mixture priors for uncertainty in the number and locations of basis functions and in the space-varying linkage coefficients. A simulation example is presented to evaluate the performance of the proposed approach with the competing models. A real data example is used for illustration.

A vector space model approach to identify genetically related diseases  

PubMed Central

Objective The relationship between diseases and their causative genes can be complex, especially in the case of polygenic diseases. Further exacerbating the challenges in their study is that many genes may be causally related to multiple diseases. This study explored the relationship between diseases through the adaptation of an approach pioneered in the context of information retrieval: vector space models. Materials and Methods A vector space model approach was developed that bridges gene disease knowledge inferred across three knowledge bases: Online Mendelian Inheritance in Man, GenBank, and Medline. The approach was then used to identify potentially related diseases for two target diseases: Alzheimer disease and Prader-Willi Syndrome. Results In the case of both Alzheimer Disease and Prader-Willi Syndrome, a set of plausible diseases were identified that may warrant further exploration. Discussion This study furthers seminal work by Swanson, et al. that demonstrated the potential for mining literature for putative correlations. Using a vector space modeling approach, information from both biomedical literature and genomic resources (like GenBank) can be combined towards identification of putative correlations of interest. To this end, the relevance of the predicted diseases of interest in this study using the vector space modeling approach were validated based on supporting literature. Conclusion The results of this study suggest that a vector space model approach may be a useful means to identify potential relationships between complex diseases, and thereby enable the coordination of gene-based findings across multiple complex diseases.

Regional centres for space science and technology education affiliated to the United Nations  

NASA Astrophysics Data System (ADS)

Capacity-building efforts in space science and technology are a major focus of the activities of the Office of Outer Space Affairs. Such efforts include providing support to the regional centres for space science and technology education, affiliated to the United Nations, whose goal is to develop, through in-depth education, an indigenous capability for research and applications in the core disciplines of: (a) remote sensing and geographical information systems; (b) satellite communications; (c) satellite meteorology and global climate; and (d) space and atmospheric sciences and data management. The regional centres are located in Morocco and Nigeria for Africa, in Brazil and Mexico for Latin America and the Caribbean and in India for Asia and the Pacific. The overall policy-making body of each Centre is its Governing Board and consists of member States (within the region where the Centre is located), that have agreed, through their endorsement of the Centre's agreement, to the goals and objectives of the Centre. The United Nations Programme on Space Applications, with the support of prominent educators, has developed standard education curricula, which were adopted by the Centres for teaching each of the four core disciplines. Within the framework of the International Committee on global navigation satellite systems (ICG), which is established as an informal body for the purpose of promoting the use and application of global navigation satellite systems (GNSS) on a global basis, the Regional Centres will also be acting as the ICG Information Centres. The ICG Information Centres aim to foster a more structured approach to information exchange in order to fulfil the reciprocal expectations of a network between ICG and Regional Centres.

A space charge model for electrophonic bursters  

NASA Astrophysics Data System (ADS)

The sounds accompanying electrophonic burster meteors are characteristically described as being akin to short duration ``pops'' and staccato-like ``clicks''. As a phenomenon distinct from the enduring electrophonic sounds that occasionally accompany the passage and ablation of large meteoroids in the Earth's lower atmosphere, the bursters have proved stubbornly difficult to explain. A straightforward calculation demonstrates that in contradistinction to the enduring electrophonic sounds, the electrophonic bursters are not generated as a consequence of interactions between the meteoroid ablation plasma and the Earth's geomagnetic field. Here we present a novel and hitherto unrecorded model for the generation of short-duration pulses in an observer's local electrostatic field. Our model is developed according to the generation of a strong electric field across a shock wave propagating in a plasma. In this sense, the electrophonic bursters are associated with the catastrophic disruption of large meteoroids in the Earth's atmosphere. We develop an equation for the description of the electric field strength in terms of the electron temperature and the electron volume density. Also, by linking the electron line density to a meteor's absolute visual magnitude, we obtain a lower limit to the visual magnitude of electrophonic burster meteors of Mv~ -6.6, in good agreement with the available observations.

Modeling techniques for gaining additional urban space  

NASA Astrophysics Data System (ADS)

One of the major accompaniments of the globalization is the rapid growing of urban areas. Urban sprawl is the main environmental problem affecting those cities across different characteristics and continents. Various reasons for the increase in urban sprawl in the last 10 to 30 years have been proposed [1], and often depend on the socio-economic situation of cities. The quantitative reduction and the sustainable handling of land should be performed by inner urban development instead of expanding urban regions. Following the principal "spare the urban fringe, develop the inner suburbs first" requires differentiated tools allowing for quantitative and qualitative appraisals of current building potentials. Using spatial high resolution remote sensing data within an object-based approach enables the detection of potential areas while GIS-data provides information for the quantitative valuation. This paper presents techniques for modeling urban environment and opportunities of utilization of the retrieved information for urban planners and their special needs.

Postcolonial foldings of space and identity in science education: limits, transformations, prospects  

NASA Astrophysics Data System (ADS)

The four essays reviewed here constitute a worthwhile attempt to discuss various aspects of postcolonial theory, and offer constructive ideas to ongoing academic as well as public conversations with respect to whether science education can meet the challenges of educating an increasingly diverse population in the 21st century. These essays are grounded in the assumption that it is difficult to make meaningful and transformative changes in science education so that educators' efforts take into consideration the dramatic changes (i.e., diverse culture and racial origins, language, economic status etc.) of `an era of globalization' in order to meet the demands of today's schools. Each of these four essays problematizes various aspects of the social and cultural conditions of science education nowadays using different `postcolonial' ideas to interpret the implications for science learning and teaching. Although the term `postcolonial' has certainly multiple meanings in the literature, we use this term here to describe the philosophical position of these essays to challenge long-standing and hegemonic practices and taken-for-granted assumptions in science education. Through critical analysis of these essays, we engage in a dialogue with the authors, focusing on two of what seem crucial issues in understanding the potential contributions as well as the risks of postcolonial concepts in science education; these issues are space and identity. We choose these issues because they permeate all four essays in interesting and often provocative ways.

A Prototype for Education Programs using Planetari and Space Centres as Key Tools  

NASA Astrophysics Data System (ADS)

Few hands on space experiments designed for school education allow the students and teachers to participate in the discovery of new science. One particularly experiment which flew on STS107 Columbia was designed specifically to do just this. A key feature of the project was to use a Zoo and a University as key tools in providing through life development and support. The project, "Spiders in Space" ran over a four year period resulted in the student and scientist team publishing over twenty refereed papers on their research findings. Throughout the project teacher and student performance, satisfaction, knowledge, abilities and competency were monitored and critically evaluated. The progressive gathering and feedback was used to improve the program and adapt the learning experience to the student needs and abilities. Based on the experience gained with the Spider Experiment on STS-107, the originating team of scientists and teachers have formulated a structure on which to facilitate the design of similar space education cross discipline projects. The project architecture presented uses as key tools Planetaria, Space science education centres, zoos and Universities in the successful delivery of the programs.The engagement of these key tools facilitates a cost effective and educationally sound support network for thousands of schools to have some ownership of their space program. These key tools provide both continuing professional development for teachers wishing to enter the program and field laboratory support for the student classes engaged in it. The resulting programs are designed to foster collaboration between space research and education on an international scale. The sample new program is presented which demonstrates the application of scientific principles by making students and teachers an integral part of current space research. Issues such as environment, climate control and biological diversity are investigated with a view to providing research outcomes in support of the European Aurora Program, the first human mission to Mars. The cross disciplinary nature of the program encourages participation from all students and promotes a team approach. The investigation incorporates topics covered in Physics, Chemistry and Biology within the current secondary school curriculum and integrates them with Economics, Construction, Project Management and International Relations.

Multifractal models for space-time rainfall downscaling  

NASA Astrophysics Data System (ADS)

It is well know that rainfall fields display fluctuations in space and time that increase as the scale of observation decreases. Multifractal theory represents a solid base to characterize scale-invariance properties observed in rainfall fields as well as to develop downscaling models able to reproduce observed statistics. The availability of such downscaling tools allows forecasting of floods in small basins by coupling meteorological and hydrological models working on different space-time grid resolution. In this talk multifractal theory will be reviewed highlighting the most relevant aspects for rainfall downscaling (e.g., the concept of scale-invariance in rainfall fields displaying space-time self-similarity or self-affinity, the role of orography). The main results of the scale-invariance analysis of rainfall retrieved by remote sensors will be discussed. Finally the application of multifractal models for rainfall downscaling will be presented and some new ideas for ensemble verification will be argued.

The National Space Biomedical Research Institute's education and public outreach program: Working toward a global 21st century space exploration society  

NASA Astrophysics Data System (ADS)

Space Exploration educators worldwide are confronting challenges and embracing opportunities to prepare students for the global 21st century workforce. The National Space Biomedical Research Institute (NSBRI), established in 1997 through a NASA competition, is a 12-university consortium dedicated to space life science research and education. NSBRI's Education and Public Outreach Program (EPOP) is advancing the Institute's mission by responding to global educational challenges through activities that: provide teacher professional development; develop curricula that teach students to communicate with their peers across the globe; provide women and minority US populations with greater access to, and awareness of science careers; and promote international science education partnerships. A recent National Research Council (NRC) Space Studies Board Report, America's Future in Space: Aligning the Civil Program with National Needs, acknowledges that "a capable workforce for the 21st century is a key strategic objective for the US space program… (and that) US problems requiring best efforts to understand and resolve…are global in nature and must be addressed through mutual worldwide action". [1] This sentiment has gained new momentum through a recent National Aeronautics and Space Administration (NASA) report, which recommends that the life of the International Space Station be extended beyond the planned 2016 termination. [2] The two principles of globalization and ISS utility have elevated NSBRI EPOP efforts to design and disseminate science, technology, engineering and mathematics (STEM) educational materials that prepare students for full participation in a globalized, high technology society; promote and provide teacher professional development; create research opportunities for women and underserved populations; and build international educational partnerships. This paper describes select EPOP projects and makes the case for using innovative, emerging information technologies to transfer space exploration knowledge to students, engage educators from across the globe in discourse about science curricula, and foster multimedia collaborations that inform citizens about the benefits of space exploration for life on Earth. Special references are made to educational activities conducted at professional meetings in Austria, Canada, France, China, Greece, Italy, Russia, Scotland and Spain.

SpaceWire model development technology for satellite architecture.  

SciTech Connect

Packet switched data communications networks that use distributed processing architectures have the potential to simplify the design and development of new, increasingly more sophisticated satellite payloads. In addition, the use of reconfigurable logic may reduce the amount of redundant hardware required in space-based applications without sacrificing reliability. These concepts were studied using software modeling and simulation, and the results are presented in this report. Models of the commercially available, packet switched data interconnect SpaceWire protocol were developed and used to create network simulations of data networks containing reconfigurable logic with traffic flows for timing system distribution.

High Resolution Space-Time Ozone Modeling for Assessing Trends.  

PubMed

The assessment of air pollution regulatory programs designed to improve ground level ozone concentrations is a topic of considerable interest to environmental managers. To aid this assessment, it is necessary to model the space-time behavior of ozone for predicting summaries of ozone across spatial domains of interest and for the detection of long-term trends at monitoring sites. These trends, adjusted for the effects of meteorological variables, are needed for determining the effectiveness of pollution control programs in terms of their magnitude and uncertainties across space. This paper proposes a space-time model for daily 8-hour maximum ozone levels to provide input to regulatory activities: detection, evaluation, and analysis of spatial patterns of ozone summaries and temporal trends. The model is applied to analyzing data from the state of Ohio which has been chosen because it contains a mix of urban, suburban, and rural ozone monitoring sites in several large cities separated by large rural areas. The proposed space-time model is auto-regressive and incorporates the most important meteorological variables observed at a collection of ozone monitoring sites as well as at several weather stations where ozone levels have not been observed. This problem of misalignment of ozone and meteorological data is overcome by spatial modeling of the latter. In so doing we adopt an approach based on the successive daily increments in meteorological variables. With regard to modeling, the increment (or change-in-meteorology) process proves more attractive than working directly with the meteorology process, without sacrificing any desired inference. The full model is specified within a Bayesian framework and is fitted using MCMC techniques. Hence, full inference with regard to model unknowns is available as well as for predictions in time and space, evaluation of annual summaries and assessment of trends. PMID:19759840

Breastfeeding as a time-varying-time-dependent factor for birth spacing: multivariate models with validations and predictions.  

PubMed

Data used in the present study are from the National Family Health Survey (NFHS-I) 1992-93 (International Institute for Population Sciences 1995), India. Our study has developed Cox model analyses to see the effect of breastfeeding as a time-varying and time-dependent factor on birth spacing. While it is acknowledged that breastfeeding has a protective effect on birth spacing, such analysis of breastfeeding allows for a more nuanced understanding of that effect. Multivariate analysis revealed that breastfeeding, ever experience of fetal loss, education of women, employment status of women, education of husband, media exposure, survival status of index child and place of residence played an important part in extending birth space in at least one of the birth-spacing intervals (first to fifth). However, the variables varied from the first birth spacing to the fifth birth spacing. Breastfeeding is the only covariate found to be a significant protective factor associated with each birth spacing. Furthermore, this study validates the developed models with their prediction utilities for birth spacing. PMID:22555118

Stereo-vision-based 3D modeling of space structures  

NASA Astrophysics Data System (ADS)

Servicing satellites in space requires accurate and reliable 3D information. Such information can be used to create virtual models of space structures for inspection (geometry, surface flaws, and deployment of appendages), estimation of relative position and orientation of a target spacecraft during autonomous docking or satellite capture, replacement of serviceable modules, detection of unexpected objects and collisions. Existing space vision systems rely on assumptions to achieve the necessary performance and reliability. Future missions will require vision systems that can operate without visual targets and under less restricted operational conditions towards full autonomy. Our vision system uses stereo cameras with a pattern projector and software to obtain reliable and accurate 3D information. It can process images from cameras mounted on a robotic arm end-effector on a space structure or a spacecraft. Image sequences can be acquired during relative camera motion, during fly-around of a spacecraft or motion of the arm. The system recovers the relative camera motion from the image sequence automatically without using spacecraft or arm telemetry. The 3D data computed can then be integrated to generate a calibrated photo-realistic 3D model of the space structure. Feature-based and shape-based approaches for camera motion estimation have been developed and compared. Imaging effects on specular surfaces are introduced by space materials and illumination. With a pattern projector and redundant stereo cameras, the robustness and accuracy of stereo matching are improved as inconsistent 3D points are discarded. Experiments in our space vision facility show promising results and photo-realistic 3D models of scaled satellite replicas are created.

Nonlinear Regime-Switching State-Space (RSSS) Models.  

PubMed

Nonlinear dynamic factor analysis models extend standard linear dynamic factor analysis models by allowing time series processes to be nonlinear at the latent level (e.g., involving interaction between two latent processes). In practice, it is often of interest to identify the phases-namely, latent "regimes" or classes-during which a system is characterized by distinctly different dynamics. We propose a new class of models, termed nonlinear regime-switching state-space (RSSS) models, which subsumes regime-switching nonlinear dynamic factor analysis models as a special case. In nonlinear RSSS models, the change processes within regimes, represented using a state-space model, are allowed to be nonlinear. An estimation procedure obtained by combining the extended Kalman filter and the Kim filter is proposed as a way to estimate nonlinear RSSS models. We illustrate the utility of nonlinear RSSS models by fitting a nonlinear dynamic factor analysis model with regime-specific cross-regression parameters to a set of experience sampling affect data. The parallels between nonlinear RSSS models and other well-known discrete change models in the literature are discussed briefly. PMID:24092487

Joint space-time geostatistical model for air quality surveillance  

NASA Astrophysics Data System (ADS)

Air pollution and peoples' generalized concern about air quality are, nowadays, considered to be a global problem. Although the introduction of rigid air pollution regulations has reduced pollution from industry and power stations, the growing number of cars on the road poses a new pollution problem. Considering the characteristics of the atmospheric circulation and also the residence times of certain pollutants in the atmosphere, a generalized and growing interest on air quality issues led to research intensification and publication of several articles with quite different levels of scientific depth. As most natural phenomena, air quality can be seen as a space-time process, where space-time relationships have usually quite different characteristics and levels of uncertainty. As a result, the simultaneous integration of space and time is not an easy task to perform. This problem is overcome by a variety of methodologies. The use of stochastic models and neural networks to characterize space-time dispersion of air quality is becoming a common practice. The main objective of this work is to produce an air quality model which allows forecasting critical concentration episodes of a certain pollutant by means of a hybrid approach, based on the combined use of neural network models and stochastic simulations. A stochastic simulation of the spatial component with a space-time trend model is proposed to characterize critical situations, taking into account data from the past and a space-time trend from the recent past. To identify near future critical episodes, predicted values from neural networks are used at each monitoring station. In this paper, we describe the design of a hybrid forecasting tool for ambient NO2 concentrations in Lisbon, Portugal.

The NASA Triad program of the American Geological Institute (AGI) and Arizona State University School of Earth and Space Exploration (ASU SESE) is a three-part effort to promote Earth and space science literacy and STEM education at the national level, funded by NASA through a cooperative agreement starting in 2010. NASA Triad comprises (1) infusion of NASA STEM content into AGI's secondary Earth science curricula; (2) national lead teacher professional development workshops; and (3) an online professional development guide for teachers running NASA STEM workshops. The Triad collaboration draws on AGI's inquiry-based curriculum and teacher professional-development resources and workforce-building programs; ASU SESE's spectrum of research in Mars and Moon exploration, astrobiology, meteoritics, Earth systems, and cyberlearning; and direct access to NASA facilities and dynamic education resources. Triad milestones to date include integration of NASA resources into AGI's print and online curricula and two week-long, national-scale, teacher-leader professional development academies in Earth and space sciences presented at ASU Dietz Museum in Tempe and NASA Johnson Space Flight Center in Houston. Robust front-end and formative assessments of these program components, including content gains, teacher-perceived classroom relevance, teacher-cohort lesson development, and teacher workshop design, have been conducted. Quantitative and qualitative findings from these assessment activities have been applied to identify best and most effective practices, which will be disseminated nationally and globally through AGI and NASA channels.

Self-similarity of phase-space networks of frustrated spin models and lattice gas models  

NASA Astrophysics Data System (ADS)

We studied the self-similar properties of the phase spaces of two frustrated spin models and two lattice gas models. The two frustrated spin models were (1) the antiferromagnetic Ising model on a two-dimensional triangular lattice (1a) at the ground states and (1b) above the ground states and (2) the six-vertex model. The two lattice gas models were (3) the one-dimensional lattice gas model and (4) the two-dimensional lattice gas model. Their phase spaces were mapped to networks so that the fractal analysis of complex networks can be applied. These phase spaces, in turn, establish new classes of networks with unique self-similar properties. Models 1a, 2, and 3 with long-range power-law correlations in real space exhibit fractal phase spaces, while models 1b and 4 with short-range exponential correlations in real space exhibit nonfractal phase spaces. This behavior agrees with one of the untested assumptions in Tsallis nonextensive statistics. All the phase spaces have power-law “mass” -radius relations that reflect the local self-similar structures.

Anatomical models for space radiation applications: an overview.  

PubMed

Extremely detailed computerized anatomical male (CAM) and female (CAF) models that have been developed for use in space radiation analyses are discussed and reviewed. Recognizing that the level of detail may currently be inadequate for certain radiological applications, one of the purposes of this paper is to elicit specific model improvements or requirements from the scientific user-community. Methods and rationale are presented which describe the approach used in the Space Shuttle program to extrapolate dosimetry measurements (skin doses) to realistic astronaut body organ doses. Several mission scenarios are presented which demonstrate the utility of the anatomical models for obtaining specific body organ exposure estimates and can be used for establishing cancer morbidity and mortality risk assessments. These exposure estimates are based on the trapped Van Allen belt and galactic cosmic radiation environment models and data from the major historical solar particle events. PMID:11539978

Path Flow Estimation Using Time Varying Coefficient State Space Model  

NASA Astrophysics Data System (ADS)

The dynamic path flow information is very crucial in the field of transportation operation and management, i.e., dynamic traffic assignment, scheduling plan, and signal timing. Time-dependent path information, which is important in many aspects, is nearly impossible to be obtained. Consequently, researchers have been seeking estimation methods for deriving valuable path flow information from less expensive traffic data, primarily link traffic counts of surveillance systems. This investigation considers a path flow estimation problem involving the time varying coefficient state space model, Gibbs sampler, and Kalman filter. Numerical examples with part of a real network of the Taipei Mass Rapid Transit with real O-D matrices is demonstrated to address the accuracy of proposed model. Results of this study show that this time-varying coefficient state space model is very effective in the estimation of path flow compared to time-invariant model.

Expanding Earth and Space Science through the Initiating New Science Partnerships In Rural Education (INSPIRE)  

NASA Astrophysics Data System (ADS)

The INSPIRE program at Mississippi State University (MSU), funded by the NSF Graduate STEM Fellows in K-12 Education (GK12) program, focuses on Earth and Space science education and has partnered ten graduate students from MSU with five teachers from local, rural school districts. For the next five years the project will serve to increase inquiry and technology experiences in science and math while enhancing graduate student’s communication skills. Graduate students, from the disciplines of Geosciences, Physics, and Engineering are partnered with Chemistry, Physical Science, Physics, Geometry and Middle school science classrooms and will create engaging inquiry activities that incorporate elements of their research, and integrate various forms of technology. The generated lesson plans that are implemented in the classroom are published on the INSPIRE home page (www.gk12.msstate.edu) so that other classroom instructors can utilize this free resource. Local 7th -12th grade students will attend GIS day later this fall at MSU to increase their understanding and interest in Earth and Space sciences. Selected graduate students and teachers will visit one of four international university partners located in Poland, Australia, England, or The Bahamas to engage research abroad. Upon return they will incorporate their global experiences into their local classrooms. Planning for the project included many factors important to the success of the partnerships. The need for the program was evident in Mississippi K-12 schools based on low performance on high stakes assessments and lack of curriculum in the Earth and Space sciences. Meeting with administrators to determine what needs they would like addressed by the project and recognizing the individual differences among the schools were integral components to tailoring project goals and to meet the unique needs of each school partner. Time for training and team building of INSPIRE teachers and graduate students before the school year aided in fostering a community atmosphere to ensure successful classroom experiences. Including stakeholders in the progress of lesson plan product development during a workshop luncheon was another key part to building a community of support for INSPIRE. These planning components are essential to the success of the project and are recommended to similar projects. The INSPIRE project external evaluation includes: (i) interviews of participants and K-12 students involved in INSPIRE, (ii) pre-post technology and teaching attitude surveys of graduate students and teachers, (iii) thematic analysis of daily feedback forms from the workshop, (iv) summary of end of workshop evaluations, and (v) constant surveying of program progress towards meeting its goals. Internal evaluation includes: (i) classroom observations of graduate student interactions with students (ii) bi-weekly journal entries from both teachers and graduate students, and (iii) weekly feedback from graduate students. Preliminary evaluation of the workshop daily feedback forms indicate a high level of approval for the technology and inquiry activities modeled. Journal entries indicate that the majority of Fellow-teacher teams experience positive interactions in the classroom.

Making long-term memories in minutes: a spaced learning pattern from memory research in education  

PubMed Central

Memory systems select from environmental stimuli those to encode permanently. Repeated stimuli separated by timed spaces without stimuli can initiate Long-Term Potentiation (LTP) and long-term memory (LTM) encoding. These processes occur in time scales of minutes, and have been demonstrated in many species. This study reports on using a specific timed pattern of three repeated stimuli separated by 10 min spaces drawn from both behavioral and laboratory studies of LTP and LTM encoding. A technique was developed based on this pattern to test whether encoding complex information into LTM in students was possible using the pattern within a very short time scale. In an educational context, stimuli were periods of highly compressed instruction, and spaces were created through 10 min distractor activities. Spaced Learning in this form was used as the only means of instruction for a national curriculum Biology course, and led to very rapid LTM encoding as measured by the high-stakes test for the course. Remarkably, learning at a greatly increased speed and in a pattern that included deliberate distraction produced significantly higher scores than random answers (p < 0.00001) and scores were not significantly different for experimental groups (one hour spaced learning) and control groups (four months teaching). Thus learning per hour of instruction, as measured by the test, was significantly higher for the spaced learning groups (p < 0.00001). In a third condition, spaced learning was used to replace the end of course review for one of two examinations. Results showed significantly higher outcomes for the course using spaced learning (p < 0.0005). The implications of these findings and further areas for research are briefly considered.

Making long-term memories in minutes: a spaced learning pattern from memory research in education.  

PubMed

Memory systems select from environmental stimuli those to encode permanently. Repeated stimuli separated by timed spaces without stimuli can initiate Long-Term Potentiation (LTP) and long-term memory (LTM) encoding. These processes occur in time scales of minutes, and have been demonstrated in many species. This study reports on using a specific timed pattern of three repeated stimuli separated by 10 min spaces drawn from both behavioral and laboratory studies of LTP and LTM encoding. A technique was developed based on this pattern to test whether encoding complex information into LTM in students was possible using the pattern within a very short time scale. In an educational context, stimuli were periods of highly compressed instruction, and spaces were created through 10 min distractor activities. Spaced Learning in this form was used as the only means of instruction for a national curriculum Biology course, and led to very rapid LTM encoding as measured by the high-stakes test for the course.

Fractal approach to mathematical modelling of space observation data  

NASA Astrophysics Data System (ADS)

Fractal approach to mathematical modelling of signals in space optical observation systems is proposed. The scannings of two-dimensional images as one-dimensional stochastic fractal processes are built on the base of Brownian motion. Integrals over trajectories of Wiener processes with different kernels are used for modeling of one-dimensional stochastic fractals and multifractals. Modelling of scannings of remotely sensed data based on formalism of integrals over Wiener stochastic process trajectories and modelling of probabilistic characteristics based on formalism of Feynman continual integrals are performed. Algorithms of multiscale detection of signals on the basis of discrete and continuous wavelet transforms are developed and applied for anomaly detection and estimation.

Common features in phase-space networks of frustrated spin models and lattice-gas models  

NASA Astrophysics Data System (ADS)

We mapped the phase spaces of the following four models into networks: (1a) the Ising antiferromagnet on triangular lattice at the ground state and (1b) above the ground state, (2) the six-vertex model (i.e. square ice or spin ice), (3) 1D lattice gas and (4) 2D lattice gas. Their phase-space networks share some common features including the Gaussian degree distribution, the Gaussian spectral density, and the small-world properties. Models 1a, 2 and 3 with long-range correlations in real space exhibit fractal phase spaces, while models 1b and 4 with short-range correlations in real space exhibit non-fractal phase spaces. This result supports one of the untested assumptions in Tsallis's non-extensive statistics.

A Phase-Space Model for Pleistocene Ice Volume  

NASA Astrophysics Data System (ADS)

We present a phase-space model that simulates Pleistocene ice volume changes based on Earth's orbital parameters. In constructing the model, we attempt to separate terms representing direct orbital forcing of ice volume change from terms representing internal forces of change. The evolution equation is first-order, except during terminations, when it is second-order. The transition between the two states is governed by a threshold in phase space, i.e., a combination of ice volume and its rate of change. Timing of terminations agrees well with age estimates for Late Pleistocene terminations. The average phase at which model terminations begin is approximately 90±90° before the maxima in all three orbital cycles. The large variability in phase is likely caused by interactions between the three cycles and ice volume. Unlike previous ice volume models, this model reproduces an increase in 100-kyr power during the mid-Pleistocene transition without any change in model parameters. This supports the hypothesis that Pleistocene variations in the 100-kyr power of glacial cycles could be caused by changes in Earth's orbital parameters, such as amplitude modulation of the 100-kyr eccentricity cycle, rather than changes within the climate system. Phase-space trace of the filtered ice-volume record (color denotes orbital forcing). Black line indicates the termination threshold.

Transitioning Space Weather Models Into Operations: The Basic Building Blocks  

NASA Astrophysics Data System (ADS)

New and improved space weather models that provide real-time or near-real time operational awareness to the long list of customers that the NOAA Space Weather Prediction Center (SWPC) serves are critically needed. Recognizing this, SWPC recently established a Developmental Testbed Center (DTC [see Kumar, 2009]) at which models will be vetted for operational use. What characteristics should models have if they are to survive this transition? The difficulties around the implementation of real-time models are many. From the stability of the data input (frequently coming from third parties) to the elevated information technology (IT) security atmosphere present everywhere, scientists and developers are confronting a series of challenges in the implementation of their models. Quinn et al. [2009] noted that “the transition challenges are numerous and require ongoing interaction between model developers and users.” However, the 2006 Report of the Assessment Committee for the National Space Weather Program (NSWP; see http://www.nswp.gov/nswp_acreport0706.pdf) found that “there is an absence of suitable connection[s] for ‘academia-to-operations’ knowledge transfer and for the transition of research to operations in general.”

High precision modeling of space-charge effects, together with accurate treatment of single-particle dynamics, is essential for designing future accelerators as well as optimizing the performance of existing machines. We describe Synergia, a high-fidelity parallel beam dynamics simulation package with fully three dimensional space-charge capabilities and a higher order optics implementation. We describe the computational techniques, the advanced human interface, and the parallel performance obtained using large numbers of macroparticles. We also perform code benchmarks comparing to semi-analytic results and other codes. Finally, we present initial results on particle tune spread, beam halo creation, and emittance growth in the Fermilab booster accelerator.

Space physiology IV: mathematical modeling of the cardiovascular system in space exploration.  

PubMed

Mathematical modeling represents an important tool for analyzing cardiovascular function during spaceflight. This review describes how modeling of the cardiovascular system can contribute to space life science research and illustrates this process via modeling efforts to study postflight orthostatic intolerance (POI), a key issue for spaceflight. Examining this application also provides a context for considering broader applications of modeling techniques to the challenges of bioastronautics. POI, which affects a large fraction of astronauts in stand tests upon return to Earth, presents as dizziness, fainting and other symptoms, which can diminish crew performance and cause safety hazards. POI on the Moon or Mars could be more critical. In the field of bioastronautics, POI has been the dominant application of cardiovascular modeling for more than a decade, and a number of mechanisms for POI have been investigated. Modeling approaches include computational models with a range of incorporated factors and hemodynamic sophistication, and also physical models tested in parabolic and orbital flight. Mathematical methods such as parameter sensitivity analysis can help identify key system mechanisms. In the case of POI, this could lead to more effective countermeasures. Validation is a persistent issue in modeling efforts, and key considerations and needs for experimental data to synergistically improve understanding of cardiovascular responses are outlined. Future directions in cardiovascular modeling include subject-specific assessment of system status, as well as research on integrated physiological responses, leading, for instance, to assessment of subject-specific susceptibility to POI or effects of cardiovascular alterations on muscular, vision and cognitive function.

Upgraded Space Debris Evolutionary Model for the Geosynchronous Earth Orbit  

NASA Astrophysics Data System (ADS)

Space debris environment evolutionary model for the geosynchronous Earth orbit region, GEODEEM, developed by Kyushu University was upgraded for better understanding. This paper explain the key features of this upgraded model. One of keys of this upgrade is that all satellites larger than 10 cm in size are tracked individually. The benefits of this upgrade are: 1) collision accidents can be estimated based upon one-by-one collision probabilities, and 2) more realistic scenarios like removing certain objects from orbits can be applied. This paper also present the latest prediction of future space debris environment from 2008 to 2108. The model indicates that explosion is the main debris production mode in next 100 years.

Amplitude Phase-Space Model for Quantum Mechanics  

NASA Astrophysics Data System (ADS)

We show that there is a close relationship between quantum mechanics and ordinary probability theory. The main difference is that in quantum mechanics the probability is computed in terms of an amplitude function, while in probability theory a probability distribution is used. Applying this idea, we then construct an amplitude model for quantum mechanics on phase space. In this model, states are represented by amplitude functions and observables are represented by functions on phase space. If we now postulate a conjugation condition, the model provides the same predictions as conventional quantum mechanics. In particular, we obtain the usual quantum marginal probabilities, conditional probabilities and expectations. The commutation relations and uncertainty principle also follow. Moreover Schrödinger's equation is shown to be an averaged version of Hamilton's equation in classical mechanics.

Stochastic model for posttillage soil pore space evolution  

NASA Astrophysics Data System (ADS)

Tillage operations disrupt surface layers of agricultural soils, creating a loosened structure with a substantial proportion of interaggregate porosity that enhances liquid and gaseous exchange properties favorable for plant growth. Unfortunately, such desirable soil tilth is structurally unstable and is susceptible to change by subsequent wetting and drying processes and other mechanical stresses that reduce total porosity and modify pore size distribution (PSD). Ability to model posttillage dynamics of soil pore space and concurrent changes in hydraulic properties is important for realistic predictions of transport processes through this surface layer. We propose a stochastic modeling framework that couples the probabilistic nature of pore space distributions with physically based soil deformation models using the Fokker-Planck equation (FPE) formalism. Three important features of soil pore space evolution are addressed: (1) reduction of the total porosity, (2) reduction of mean pore radius, and (3) changes in the variance of the PSD. The proposed framework may be used to provide input to hydrological models concerning temporal variations in near-surface soil hydraulic properties. In a preliminary investigation of this approach we link a previously proposed mechanistic model of soil aggregate coalescence to the stochastic FPE framework to determine the FPE coefficients. An illustrative example is presented which describes changes in interaggregate pore size due to wetting-drying cycles and the resulting effects on dynamics of the soil water characteristic curve and hydraulic conductivity functions.

Space charge templates for high-current beam modeling  

SciTech Connect

A computational method to evaluate space charge potential and gradients of charged particle beam in the presence of conducting boundaries, has been introduced. The three-dimensional (3D) field of the beam can be derived as a convolution of macro Green's functions (template fields), satisfying the same boundary conditions, as the original beam. Numerical experiments gave a confidence that space charge effects can be modeled by templates with enough accuracy and generality within dramatically faster computational times than standard combination: a grid density + Poisson solvers, realized in the most of Particle in Cell codes. The achieved rapidity may significantly broaden the high-current beam design space, making the optimization in automatic mode possible, which so far was only feasible for simplest self-field formulations such as rms envelope equations. The template technique may be used as a standalone program, or as an optional field solver in existing beam dynamics codes both in one-passage structures and in rings.

Modeling natural space ionizing radiation effects on external materials  

NASA Astrophysics Data System (ADS)

Predicting the effective life of materials for space applications has become increasingly critical with the drive to reduce mission cost. Programs have considered many solutions to reduce launch costs including novel, low mass materials and thin thermal blankets to reduce spacecraft mass. Determining the long-term survivability of these materials before launch is critical for mission success. This presentation will describe an analysis performed on the outer layer of the passive thermal control blanket of the Hubble Space Telescope. This layer had degraded for unknown reasons during the mission, however ionizing radiation (IR) induced embrittlement was suspected. A methodology was developed which allowed direct comparison between the energy deposition of the natural environment and that of the laboratory generated environment. Commercial codes were used to predict the natural space IR environment, model energy deposition in the material from both natural and laboratory IR sources, and design the most efficient test. Results were optimized for total and local energy deposition with an iterative spreadsheet. This method has been used successfully for several laboratory tests at the Marshall Space Flight Center. The study showed that the natural space IR environment, by itself, did not cause the premature degradation observed in the thermal blanket.

Promoting mental model building in astronomy education  

NASA Astrophysics Data System (ADS)

While astronomy has recently re-emerged in many science curricula, there remain unresolved teaching and learning difficulties peculiar to astronomy education. This paper argues that mental model building, the core process in astronomy itself, should be reflected in astronomy education. Also, this crucial skill may promote a better understanding of the nature of science by pupils and it resonates with current understandings about pupils' learning in science. However, three practical questions to be considered are: the expressed reservations about the connection between mental model building and meaningful learning; the earliest age of pupils for whom mental model building is appropriate; and the lack of research into pupils' prior ideas about the role of models in science. The paper describes how a four-phase general pedagogical strategy was adopted to create an astronomy teaching and learning package to promote mental model building. The package consists of notes explaining the mental model building followed by an overview of the teaching-learning approach and suggested outlines of the 12 lessons. Research investigated whether that package can help Year 7-8 pupils interrogate and refine their mental models of the Sun-Earth-Moon system within the constraints of an ordinary class of 33 pupils. The results showed that all four phases of the general strategy were necessary and effective in that most pupils were able successively and successfully to critique their mental models of the Sun-Earth-Moon system while also achieving traditional astronomy knowledge goals. Implications are that pupils as young as Year 7-8 may be able to construct other appropriate mental models, such as those for biological populations, atomic structure and plate tectonics.

Populations for a divine-based space debris model  

NASA Astrophysics Data System (ADS)

A new analytical tool to calculate flux and spatial density resulting from space debris was developed with the aim to allow fast and accurate analysis for any target orbit and altitudes ranging from LEO to GEO. The model is based on the approach presented by N. Divine in 1993, which was developed for the meteoroid flux analysis. This approach was adapted to the Earth's debris environment, and is implemented in ESA's meteoroid and space debris reference model MASTER'99 as so called 'Standard application'. An extended version of the model called DIADEM, which is restricted to flux and spatial density analysis at high altitudes, includes a debris particle cloud model. This model may be applied to known cloud generation events, e.g. solid rocket motor (SRM) firings. The accuracy of the analysis results of the Divine-based model is essentially depending on the implementation of the underlying debris population. This applies to both the background population and to particle clouds. This paper is intended to describe the adaptation of the MASTER reference population to the needs of the new model, and to give a survey of its cloud modelling capabilities.

Modeling irregularly spaced residual series as a continuous stochastic process  

NASA Astrophysics Data System (ADS)

In this paper, the background and functioning of a simple but effective continuous time approach for modeling irregularly spaced residual series is presented. The basic equations were published earlier by von Asmuth et al. (2002), who used them as part of a continuous time transfer function noise model. It is shown that the methods behind the model are build on two principles: The first is the fact that the equations of a Kalman filter degenerate to a form that is equivalent to "conventional" autoregressive moving average (ARMA) models when the modeled data are considered to be free of measurement errors. This assumption, in comparison to the "full" Kalman filter, also yields a better prediction efficiency (Ahsan and O'Connor, 1994). The second is the mathematical equivalence between discrete time AR parameters and continuous exponentials and the point that continuous time models provide an elegant solution for modeling irregularly spaced observations (e.g., Harvey, 1989). Because simple least squares methods do not apply in case of modeling irregular data, a sum of weighted squared innovations (?W?I) criterion is introduced and derived from the likelihood function of the innovations. In an example application it is shown that the estimates of the ?W?I criterion converge to maximum likelihood estimates for larger sample sizes. Finally, we propose to use the so-called innovation variance function as an additional diagnostic check, next to the well-known autocorrelation and cross-correlation functions.

Towards science educational spaces as dynamic and coauthored communities of practice  

NASA Astrophysics Data System (ADS)

In this essay review, four studies around the themes of identity and globalization are summarized and analyzed. The researchers' perspectives are generally grounded in Brown and Campione's ideas on situated knowledge ( Classroom lessons: Integrating cognitive theory and classroom practice (pp. 229-270). Cambridge: The MIT Press/Bradford Books, 1994) and Lave and Wenger's definition of learning as an activity fostered through participation in communities of practice ( Situated learning. Legitimate peripheral participation. Cambridge: University of Cambridge Press, 1991). Questions about the goals of science education spaces, the nature of globalization in relation to practices in schools, the role of identities-in-practice in relation to participation in communities of practice such as classrooms are explored. Recommendations for key design features in effective science educational spaces, based upon the findings presented in the collection of four studies, are offered. School, it is suggested here, functions best as a clearing house for the myriad science-related stories student participants generate in their various communities of practice (e.g., within popular culture, family, community, informal educational sites). In this way, school has the potential to construct bridges between multiple student experiences and identities-in-practice.

Nuclear model calculations and their role in space radiation research  

NASA Astrophysics Data System (ADS)

Proper assessments of spacecraft shielding requirements and concomitant estimates of risk to spacecraft crews from energetic space radiation requires accurate, quantitative methods of characterizing the compositional changes in these radiation fields as they pass through thick absorbers. These quantitative methods are also needed for characterizing accelerator beams used in space radiobiology studies. Because of the impracticality/impossibility of measuring these altered radiation fields inside critical internal body organs of biological test specimens and humans, computational methods rather than direct measurements must be used. Since composition changes in the fields arise from nuclear interaction processes (elastic, inelastic and breakup), knowledge of the appropriate cross sections and spectra must be available. Experiments alone cannot provide the necessary cross section and secondary particle (neutron and charged particle) spectral data because of the large number of nuclear species and wide range of energies involved in space radiation research. Hence, nuclear models are needed. In this paper current methods of predicting total and absorption cross sections and secondary particle (neutrons and ions) yields and spectra for space radiation protection analyses are reviewed. Model shortcomings are discussed and future needs presented.

Space-time array processing: The model-based approach  

SciTech Connect

A method of space{endash}time array processing is introduced that is based on the model-based approach. The signal and measurement systems are placed into state-space form, thereby allowing the unknown parameters of the model, such as signal bearings, to be estimated by an extended Kalman filter. A major advantage of the model-based approach is that there is no inherent limitation to the degree of sophistication of the models used, and therefore it can deal with other than plane-wave models, such as cylindrically or spherically spreading propagation models, as well as more sophisticated representations such as the normal mode and the parabolic equation propagation models. Since the processor treats the parameters of interest as unknown parameters to be estimated, there is no explicit beamformer structure, and therefore no accuracy limitations such as fixed beam bin sizes and predetermined number of preformed beams. After a theoretical exposition of the underlying theory, the performance of the processor is evaluated with synthesized data sets. The results indicate that the method is a highly effective approach that is capable of significantly outperforming conventional array processors. {copyright} {ital 1997 Acoustical Society of America.}

Education  

NASA Astrophysics Data System (ADS)

Government schools in Congo kinshasa are not providing quality education to the masses since many years, and this phenomenon has not escaped the eyes of experts, activists, and policy makers. However, there seems to be a general perception that the main, and sometimes even the sole, source of this problem are the low levels of government expenditure of education. And to prove their case supports of this view cite educational expenditure to GDP ratios in Congo kinshasa in comparison with that of some other nations. Though there may be reasonable arguments to increase the level of government expenditure on education, such hijacking of public debate to focus on - the level of expenditure - often overlooks more important issues. Contrary to common perception the level of per student expenditure on government schools in Delhi is reasonable, ranging from Fc.6000 to Fc.12000 p.a. There are a number of organisational deficiencies which do not create checks and balances for appropriate utilization of fund. Moreover, the division of these funds among social groups and for different purposes is also questionable. Though, female literacy lags significantly behind male literacy, about 15% points, extra resources provided for female education are insignificant. And in some schemes such as the one run for 'street children' and 'child labourers', large amounts are budgeted year after year without a single French congolese being spent. Also government schools catering to richer regions of Kinshasa seem to be spending more per child as compared to the poorer counterparts. The paper also proposes an education voucher model, which may have the potential to address some of the issues raised in the paper. Trends in expenditure under some schemes have been studied in relation to the purpose of expenditure. The issue of government expenditure on education is a complex one, and public space should be utilized to discuss them as they are, rather than reducing discussion to dogmatic wars aimed at increasing the levels of expenditure. Though, one may agree or disagree with the methods and findings of the author, hopefully the paper highlight the complexity of the issue at hand, and the need to understand the institutional deficiencies and allocative inefficiencies in government expenditure on education.

Geospatial Education in Alaska's High Schools: A new Initiative of the Alaska Space Grant Program  

NASA Astrophysics Data System (ADS)

In the summer of 2004, the Alaska Space Grant Program (ASGP) made its first step to start a new and unique initiative to bring geospatial education to the high schools. Setting up this education outreach effort in the largest of the 50 states of US that has a population density of about one person per square mile, has its unique benefits and challenges. It is particularly rewarding as one reaches out to distant native and minority communities in their own local environment. Introducing Earth and Space Science topics with a geospatial context makes such educational efforts of local relevance. Training in the use of Earth and Space Science data and tools is of practical significance to the distant communities and also contributes to the development of a new technically skilled geospatial workforce that is prepared to meet the state and national needs. In the summer of 2004 ASGP ran the first two week summer workshop on "Global Positioning System (GPS) and Geographic Information System (GIS) for Alaska School Teachers". Fourteen high school teachers from various parts of the state participated and received training on the use of GPS and GIS and carried out small projects of significance to their local regions. Follow up visits were made by the course instructors to some selected schools and within six months, two high schools incorporated these in their class room teaching (www.gi.alaska.edu/~prakash/teaching/geos595). To reach out to schools that do not have well established computational facilities, ASGP build a mobile GIS laboratory with 15 laptops-GPS-GIS software assemblage. This mobile set up will be used in the second two week summer course scheduled to be run in June 2005. This batch of teachers will be more comfortable introducing GPS/GIS technology in their class rooms where they will have the possibility to use the same hardware and software setup as they used during their training, ensuring even greater success of this initiative.
