Sample records for technology space competition

  1. Competition in the market for space heating. District heating as the infrastructure for competition among fuels and technologies

    International Nuclear Information System (INIS)

    Grohnheit, Poul Erik; Gram Mortensen, Bent Ole


    None of the EU directives on liberalisation of the electricity and gas markets are considering the district heating systems, although the district heating networks offer the possibility of competition between natural gas and a range of other fuels on the market for space heating. Cogeneration of electricity and heat for industrial processes or district heating is a technology option for increased energy efficiency and thus reduction of CO 2 emissions. In the mid-1990s less than 10% of the electricity generation in the European Union was combined production with significant variations among Member States. These variations are explained by different national legislation and relative power of institutions, rather than difference in industrial structure, climate or urban physical structure. The 'single energy carrier' directives have provisions that support the development of combined heat and power (CHP), but they do not support the development and expansion of the district heating infrastructure. The article is partly based on a contribution to the Shared Analysis Project for the European Commission DG Energy, concerning the penetration of CHP, energy saving, and renewables as instruments to meet the targets of the Kyoto Protocol within the liberalised European energy market. The quantitative and legal differences of the heat markets in selected Member States are described, and the consequences of the directives are discussed. Finally, we summarise the tasks for a European policy concerning the future regulation of district heating networks for CHP, emphasising the need for rules for a fair competition between natural gas and district heating networks

  2. Technology and Competitiveness


    Jan Fagerberg


    This paper reviews the literature on technology and competitiveness. First, the concept of the international competitiveness of a country, and various theoretical approaches on the relationship between trade and growth, are discussed. Then a number of empirical studies of the impact of technology (as evidenced by R&D, patents, etc.) on exports are examined. The final section summarizes the evidence and considers the lessons for policy.

  3. Technology competition and regulatory advantage


    Boscheck, Ralf


    The importance of competition law as a policy lever to help the EU compete at the forefront of science and technology seems to have been overlooked by the Commission. As a consequence, the EU appears to be at a disadvantage to the USA in terms of the regulatory environment for intellectual property and licensing practices. This article examines these differences and explores the pros and cons of the European and American approaches to competition law, ultimately arguing in favour of regulator...

    By letter dated 27 April 2011, the Director General of the Centre for Strategic Analysis, Vincent Chriqui, confided to Jean Bergougnoux, honorary president of the SNCF, Honorary General Director of EDF, the task of animating a reflection Prospective Technological Studies of the sectors of energy, transport and construction. This synthesis report, prepared with the assistance of rapporteurs Centre for Strategic Analysis, attempts to summarize and put into perspective all the work which show these specific reports. Admittedly some very complex issues still need supplements. It may therefore be useful to extend this work in a number of areas. Beyond its role in the competitiveness of a country, technological innovation is essential to provide appropriate responses to the challenges of our commitment to sustainable development in terms of economic growth, preservation of the environmental and social progress. Mission for Prospective Technological conducted by the Centre for Strategic Analysis has sought to clarify this dual problem by proposing a long-term vision for the energy, transport and construction. For each technology studied, it has attempted to assess both the possible contribution to sustainable development and the competitive potential of our country on the international scene. His work, chaired by Jean Bergougnoux have reviewed the technological advances that may occur in the coming decades in the sectors concerned. They examined the conditions for integration of these advances in systems and subsystems existing (or create) and the conditions of a mature technical, economic but also social. Wherever possible, two time horizons were identified: a medium-term horizon, 2030, for which we have a fairly clear vision of future developments and long-term horizon, 2050, which allows to consider jumps Scientists are still uncertain. Finally, the mission is interested in four transverse technologies involved consistently in the three study areas, which are likely to

    Competition can profoundly affect biodiversity patterns by determining whether similar species are likely to coexist. When species compete directly for space, competitive ability differences should theoretically promote trait and phylogenetic clustering, provided that niche differences are otherwise minimal. Yet many sessile communities exhibit high biodiversity...

  7. Competition and evolution in restricted space

    International Nuclear Information System (INIS)

    Forgerini, F L; Crokidakis, N


    We study the competition and the evolution of nodes embedded in Euclidean restricted spaces. The population evolves by a branching process in which new nodes are generated when up to two new nodes are attached to the previous ones at each time unit. The competition in the population is introduced by considering the effect of overcrowding of nodes in the embedding space. The branching process is suppressed if the newborn node is closer than a distance ξ to the previous nodes. This rule may be relevant to describe a competition for resources, limiting the density of individuals and therefore the total population. This results in an exponential growth in the initial period, and, after some crossover time, approaching some limiting value. Our results show that the competition among the nodes associated with geometric restrictions can even, for certain conditions, lead the entire population to extinction. (paper)

  14. Advanced space transportation technologies (United States)

    Raj, Rishi S.


    A wide range of propulsion technologies for space transportation are discussed in the literature. It is clear from the literature review that a single propulsion technology cannot satisfy the many mission needs in space. Many of the technologies tested, proposed, or in experimental stages relate to: chemical and nuclear fuel; radiative and corpuscular external energy source; tethers; cannons; and electromagnetic acceleration. The scope and limitation of these technologies is well tabulated in the literature. Prior experience has shown that an extensive amount of fuel needs to be carried along for the return mission. This requirement puts additional constraints on the lift off rocket technology and limits the payload capacity. Consider the possibility of refueling in space. If the return fuel supply is guaranteed, it will not only be possible to lift off more payload but also to provide security and safety of the mission. Exploration to deep space where solar sails and thermal effects fade would also be possible. Refueling would also facilitate travel on the planet of exploration. This aspect of space transportation prompts the present investigation. The particle emissions from the Sun's corona will be collected under three different conditions: in space closer to the Sun, in the Van Allen Belts; and on the Moon. It is proposed to convert the particle state into gaseous, liquid, or solid state and store it for refueling space vehicles. These facilities may be called space pump stations and the fuel collected as space fuel. Preliminary estimates of fuel collection at all three sites will be made. Future work will continue towards advancing the art of collection rate and design schemes for pumping stations.

  17. A commercial space technology testbed on ISS (United States)

    Boyle, David R.


    There is a significant and growing commercial market for new, more capable communications and remote sensing satellites. Competition in this market strongly motivates satellite manufacturers and spacecraft component developers to test and demonstrate new space hardware in a realistic environment. External attach points on the International Space Station allow it to function uniquely as a space technology testbed to satisfy this market need. However, space industry officials have identified three critical barriers to their commercial use of the ISS: unpredictable access, cost risk, and schedule uncertainty. Appropriate NASA policy initiatives and business/technical assistance for industry from the Commercial Space Center for Engineering can overcome these barriers. .

  18. Dual Space Technology Transfer (United States)

    Kowbel, W.; Loutfy, R.


    Over the past fifteen years, MER has had several NASA SBIR Phase II programs in the area of space technology, based upon carbon-carbon (C-C) composites. In addition, in November 2004, leading edges supplied by MER provided the enabling technology to reach a Mach 10 record for an air breathing engine on the X-43 A flight. The MER business model constitutes a spin-off of technologies initially by incubating in house, and ultimately creating spin-off stand alone companies. FMC was formed to provide for technology transfer in the area of fabrication of C-C composites. FMC has acquired ISO 9000 and AS9100 quality certifications. FMC is fabricating under AS9100 certification, flight parts for several flight programs. In addition, FMC is expanding the application of carbon-carbon composites to several critical military programs. In addition to space technology transfer to critical military programs, FMC is becoming the world leader in the commercial area of low-cost C-C composites for furnace fixtures. Market penetrations have been accomplished in North America, Europe and Asia. Low-cost, quick turn-around and excellent quality of FMC products paves the way to greatly increased sales. In addition, FMC is actively pursuing a joint venture with a new partner, near closure, to become the leading supplier of high temperature carbon based composites. In addition, several other spin-off companies such as TMC, FiC, Li-Tech and NMIC were formed by MER with a plethora of potential space applications.

  19. Italian competitiveness in high technology industries

    International Nuclear Information System (INIS)

    Ferrari, S.; Palma, D.; Amendola, G.


    A sectoral analysis of 1978-1991 trends in the invention, manufacturing and marketing, in Italy, of high technology goods suggests the need for greater R ampersand D investment by government and private industry and a broadening of the number and type of industries now contributing to the strengthening of this nation's overall high technology industrial base. This is especially the case with regard to the electronics sector in view of the strategic importance of this vital industry and the strong competition being given by the newly industrialized countries located on the Pacific Rim. With reference to the European Communities common market strategies, intended as a buffer against future unified efforts by North American and Pacific Rim countries to consolidate global market share in high technology goods, recent investment trends reveal that Italy's response thus far has been slow and asymmetric

  20. Advanced manufacturing: Technology and international competitiveness

    Energy Technology Data Exchange (ETDEWEB)

    Tesar, A.


    Dramatic changes in the competitiveness of German and Japanese manufacturing have been most evident since 1988. All three countries are now facing similar challenges, and these challenges are clearly observed in human capital issues. Our comparison of human capital issues in German, Japanese, and US manufacturing leads us to the following key judgments: Manufacturing workforces are undergoing significant changes due to advanced manufacturing technologies. As companies are forced to develop and apply these technologies, the constituency of the manufacturing workforce (especially educational requirements, contingent labor, job content, and continuing knowledge development) is being dramatically and irreversibly altered. The new workforce requirements which result due to advanced manufacturing require a higher level of worker sophistication and responsibility.

  1. Technology Assessment Need: Review on Attractiveness and Competitiveness (United States)

    Salwa Sait, Siti; Merlinda Muharam, Farrah; Chin, Thoo Ai; Sulaiman, Zuraidah


    Technology assessment is crucial in managing technology for the purpose of technology exploitation. With business environment continuously changing, firms have to address this issue critically as technology is considered one of the important elements to evaluate performance and gain competitive advantage. Missteps in deciding the best technology to be developed, employed or maintained would cost the firm overall value. To fulfil the need of finding the appropriate scale to assess suitable technology, this paper summarizes that technology assessment (TA) should cover two main aspects, namely technology attractiveness and competitiveness. These components are seen capable to link the scale suggested towards evaluation of financial and non-financial performance towards competitive advantage.

  3. A Process for Technology Prioritization in a Competitive Environment (United States)

    Stephens, Karen; Herman, Melody; Griffin, Brand


    This slide presentation reviews NASA's process for prioritizing technology requirements where there is a competitive environment. The In-Space Propulsion Technology (ISPT) project is used to exemplify the process. The ISPT project focuses on the mid level Technology Readiness Level (TRL) for development. These are TRL's 4 through 6, (i.e. Technology Development and Technology Demonstration. The objective of the planning activity is to identify the current most likely date each technology is needed and create ISPT technology development schedules based on these dates. There is a minimum of 4 years between flight and pacing mission. The ISPT Project needed to identify the "pacing mission" for each technology in order to provide funding for each area. Graphic representations show the development of the process. A matrix shows which missions are currently receiving pull from the both the Solar System Exploration and the Sun-Solar System Connection Roadmaps. The timeframes of the pacing missions technologies are shown for various types of propulsion. A pacing mission that was in the near future serves to increase the priority for funding. Adaptations were made when budget reductions precluded the total implementation of the plan.

  4. Use of technology to provide competitive advantage

    International Nuclear Information System (INIS)

    Clark, P. D.


    The role of technology in plotting a new paradigm is explored by means of reviewing NOVA Chemicals' technology strategy for feedstocks, petrochemicals and polymers. As part of this transformation of technology from that of a servant to a key contributor to the success of the company, the expansion (in a 50/50 joint venture with DOW/Union Carbide) of a mammoth 2.8 billion pound ethylene plant at Joffre, Alberta is 'the jewel in the crown'. This plant, with the two ethylene units already on site will make Joffre in the year 2000 the world's largest single site for the manufacture of ethylene. An 800 million pound Advanced SCLAIRTECH T M polystyrene plant, (a proprietary process for the manufacture of high performance polymers initially developed, but considered 'non-strategic' to their own needs, by DuPont and sold to NOVA Chemicals for $ 45 million in 1994), the largest single train of its kind in the world, is also under construction. Also in the early stages of construction on the site is a large linear alpha olefin plant owned by BP-Amoco to supply co-monomer to the polyethylene plant, To back up these facilities, there is a 400 MW cogeneration unit to supply power and steam. NOVA Chemicals Research and Technology Laboratory is a focused world class research facility with an annual budget of $ 37 million, combined with the active collaboration with all major Canadian universities, and targeted projects with other universities around the world , are all necessary components of creating and acquiring the technology that is required to achieve the corporate goals of the company. The high level of investment in research and technology is seen as the pathway to fundamentally change the business and create value which can be realized in the marketplace. Research and technology also help the company to advance the competitiveness of their own processes, keep the company on the cutting edge of technology, and assure its survival among the leaders of the industry

  5. Competitiveness basis of integrated PWR technology

    International Nuclear Information System (INIS)

    Florido, Pablo C.; Bergallo, Juan E.


    The present nuclear power market is dominated by LWR, with a minor fraction of CANDU contribution due to its advantages in small and medium electric grid. Nowadays the demand for nuclear reactors is concentrated in Asia and this situation will probably not change in the short and medium term, even under the financial crisis. The Asian market needs large plants, and feedback regarding demand and products has been done (AP 600 and Sbwr) in studies of passive systems to higher power range. Present active nuclear power programs take place in countries with high GNP growth and related electricity energy demand far from expectancies in the '80. Four of these countries were in the list of the top 10 most dynamical nations. Traditionally, nuclear countries have large economies and electric grids or strong national nuclear commitment. However, in the near future the demand of nuclear reactors seems to move towards faster growing economies and countries, with new electrical grids. From the point of view of the competitiveness, higher power nuclear plants are seriously questioned in this new market. The International Atomic Energy Agency has promoted studies in the field of small nuclear power plants (around 300 M We) for a long time. These designs have never reached commercial level in industrialized countries. One reason has been that the reactor technology naturally moves towards the best economy, i.e. the greater power. The second reason has been that the nuclear designers were always in countries with large electric systems. Consequently the utilities never have been attracted by prototypes of small reactors. The only option to develop a competitive medium nuclear reactors is to develop a design with different scale economy, like the scale economy of CCGT. If LWR technology is used, the design could be the best alternative for the utilities, because the availability of present LWR is one of the main advantages as a proved power source. The most promising type of LWR with

    Space technology needs nuclear power to solve its future problems. Manned space flight to Mars is hardly feasible without nuclear propulsion, and orbital nuclear power lants will be necessary to supply power to large satellites or large space stations. Nuclear power also needs space technology. A nuclear power plant sited on the moon is not going to upset anybody, because of the high natural background radiation level existing there, and could contribute to terrestrial power supply.

  11. Technology transfer from the space exploration initiative

    International Nuclear Information System (INIS)

    Buden, D.


    Space exploration has demonstrated that it stimulates the national economy by creating new and improved products, increased employment, and provides a stimulus to education. The exploration of the Moon and Mars under the Space Exploration Initiative has the potential of accelerating this stimulates to the economy. It is difficult to identify all of the concrete ways this will be accomplished. However, many areas can be identified. The space exploration building blocks of power, propulsion, spacecraft, robotics, rovers, mining and manufacturing, communications, navigation, habitats, life support and infrastructures are reviewed to identify possible technology areas. For example, better means for working in hazardous areas and handling hazardous waste are potential outcomes of this initiative. Methods to produce higher quality goods and improve America's competitiveness in manufacturing will undoubtedly evolve from the need to produce products that must last many years in the harsh environments of space and planetary surfaces. Some ideas for technology transfer are covered in this paper

  19. Space technology developments in Malaysia: (United States)

    Sabirin, A.

    The venture of space is, by nature, a costly one. However, exploring space is not just an activity reserved for international superpowers. Smaller and emerging space nations, some with burgeoning space programs of their own, can play a role in space technology development and interplanetary exploration, sometimes simply by just being there. Over the past four decades, the range of services delivered by space technologies in Malaysia has grown enormously. For many business and public services, space based technologies have become the primary means of delivery of such services. Space technology development in Malaysia started with Malaysia's first microsatellite, TiungSAT-1. TiungSAT-1 has been successfully launched from the Baikonur Cosmodrome, Kazakhstan on the 26th of September 2000 on a Russian-Ukrainian Dnepr rocket. There have been wide imaging applications and information extraction using data from TiungSAT-1. Various techniques have been applied to the data for different applications in environmental assessment and monitoring as well as resource management. As a step forward, Malaysia has also initiated another space technology programme, RAZAKSAT. RAZAKSAT is a 180kg class satellite designed to provide 2.5meter ground sampling distance resolution imagery on a near equatorial orbit. Its mission objective is to demonstrate the capability of a medium high resolution remote sensing camera using a cost effective small satellite platform and a multi-channel linear push-broom electro-optical instrument. Realizing the immense benefits of space technology and its significant role in promoting sustainable development, Malaysia is committed to the continuous development and advancement of space technology within the scope of peaceful use of outer space and boosting its national economic growth through space related activities.

    Space construction systems made feasible by an operational Space Shuttle are discussed with a view toward assembly, installation and construction support equipment. The level of construction capability will be reflected in the number of launches to accomplish a certain mission, either in terms of the mission time line or on the density of packaging in the Orbiter payload bay. It is noted that the development of construction support equipment in zero-gravity simulations should be the most productive initial activity. Crew EVAs, as well as the beam builder, cherrypicker and power distribution buses are covered in detail.

  4. NASA Space Laser Technology (United States)

    Krainak, Michael A.


    Over the next two decades, the number of space based laser missions for mapping, spectroscopy, remote sensing and other scientific investigations will increase several fold. The demand for high wall-plug efficiency, low noise, narrow linewidth laser systems to meet different systems requirements that can reliably operate over the life of a mission will be high. The general trends will be for spatial quality very close to the diffraction limit, improved spectral performance, increased wall-plug efficiency and multi-beam processing. Improved spectral performance will include narrower spectral width (very near the transform limit), increased wavelength stability and or tuning (depending on application) and lasers reaching a wider range of wavelengths stretching into the mid-infrared and the near ultraviolet. We are actively developing high efficiency laser transmitter and high-sensitivity laser receiver systems that are suitable for spaceborne applications.

    Full Text Available A determined effort of companies to improve their potential of success-ability through a development of their own competitiveness is very significantly reflected in the nature of their competitive environment. A question can be asked: what changes are introduced and what their mechanism is. The main objective of this article has been to define a theoretical background to a principle of a competitive space demands accelerator and its impacts on deterioration and sustainability of competitive advantages. The methodology used is based upon a success-ability concept. The success-ability concept describes behavior of companies in the way which – from the point of an approach to competitiveness development – is able to identify specific features, frequently neglected by conventional approaches. Presented paper defines a mechanism of growing level of demands of competitive environment especially in the context of three key factors – company, its competitors and customers and their needs. The paper explains a paradox - an endeavor to gain higher level of advantage results in a rapid deterioration of new, achieved level of such advantage, in the sense of a lead over competitors, practically very soon after securing of such advantage.

  6. Commercial Space with Technology Maturation (United States)

    McCleskey, Carey M.; Rhodes, Russell E.; Robinson, John W.


    To provide affordable space transportation we must be capable of using common fixed assets and the infrastructure for multiple purposes simultaneously. The Space Shuttle was operated for thirty years, but was not able to establish an effective continuous improvement program because of the high risk to the crew on every mission. An unmanned capability is needed to provide an acceptable risk to the primary mission. This paper is intended to present a case where a commercial space venture could share the large fixed cost of operating the infrastructure with the government while the government provides new advanced technology that is focused on reduced operating cost to the common launch transportation system. A conceivable commercial space venture could provide educational entertainment for the country's youth that would stimulate their interest in the science, technology, engineering, and mathematics (STEM) through access at entertainment parks or the existing Space Visitor Centers. The paper uses this example to demonstrate how growing public-private space market demand will re-orient space transportation industry priorities in flight and ground system design and technology development, and how the infrastructure is used and shared.

  7. Space weapon technology and policy (United States)

    Hitchens, Theresa


    The military use of space, including in support of nuclear weapons infrastructure, has greatly increased over the past 30 years. In the current era, rising geopolitical tensions between the United States and Russia and China have led to assumptions in all three major space powers that warfighting in space now is inevitable, and possible because of rapid technological advancements. New capabilities for disrupting and destroying satellites include radio-frequency jamming, the use of lasers, maneuverable space objects and more capable direct-ascent anti-satellite weapons. This situation, however, threatens international security and stability among nuclear powers. There is a continuing and necessary role for diplomacy, especially the establishment of normative rules of behavior, to reduce risks of misperceptions and crisis escalation, including up to the use of nuclear weapons. U.S. policy and strategy should seek a balance between traditional military approaches to protecting its space assets and diplomatic tools to create a more secure space environment.

  11. Understanding Dynamic Competitive Technology Diffusion in Electronic Markets (United States)

    Zhang, Cheng; Song, Peijian; Xu, Yunjie; Xue, Ling

    The extant literature on information technology (IT) diffusion has largely treated technology diffusion as a generic and independent process. This study, in contrast, examines the diffusion of different IT products with brand differentiation and competition. Drawing upon existing theories of product diffusion, we propose a research model to capture the dynamics of the competitive diffusion of web-based IT products and validate it with longitudinal field data of e-business platforms. Our findings suggest that IT product diffusion can be better predicted by a competitive model than by an independent-diffusion-process model. This research extends IT research to the context of competitive diffusion and provides practitioners an effective model to predict the dissemination of their products. The research also suggests the existence of asymmetric interactions among competing products, prompting scholars and practitioners to pay attention to the influence of competing products when making forecast of their product market.

  12. Marketing technologies for building competitiveness of companies export

    Directory of Open Access Journals (Sweden)

    Tatyana Tsygankova


    Full Text Available In context of post-industrial development of global economy, escalating competition in international goods markets, the definition of competitive export is proposed based upon both existing criteria – sustainability, effectiveness, adaptivity and fair competition, and on those described in the work – ecological performance, service maintenance, brand awareness and high technology. Given that, it is proved that with the aim of detailing the elements of competitive export, the latter should be typified depending upon the performer (export competitiveness of a company, country, region and subject (export competitiveness of goods, services, rights upon intellectual property objects, keeping in mind universal and specific features of export criteria proposed to be characterised through a range of indices on corporate and state levels. Groups of factors affecting export competitiveness building are systematized (institutional, financial and economic, marketing, foreign trade, scientific and technological, resource-related and social and ecological. Marketing technologies are typified on corporate level under the following criteria: novelty, object, creative component availability, internationalization stages, international marketing forms, digitalization level, management functions, customer-centreness scale, international marketing activity stages, financial security, specific features of intercorporate coordination. The practice of applying international marketing technologies by companies is investigated. In context of necessity to overcome crisis phenomena and increase competitive export volume, an assessment is made of integrating national manufacturing into regulated global chains of creating added value with the relevant rating, in particular, depending upon the available potential, minimality of technical and organizational changes, marketing relevancy, enabling to determine the manufacturing areas most prepared to cooperation, and

    Haines, R. F.


    The results of the NASA/AIA space station interior national design competition held during 1971 are presented in order to make available to those who work in the architectural, engineering, and interior design fields the results of this design activity in which the interiors of several space shuttle size modules were designed for optimal habitability. Each design entry also includes a final configuration of all modules into a complete space station. A brief history of the competition is presented with the competition guidelines and constraints. The first place award entry is presented in detail, and specific features from other selected designs are discussed. This is followed by a discussion of how some of these design features might be applied to terrestrial as well as space situations.

  16. International cooperation and competition in space - A current perspective (United States)

    Pedersen, K. S.


    International cooperative efforts undertaken by NASA are evaluated and consideration is given to the proposed space station. The Shuttle RMS and Spacelab were constructed through efforts of Canadian and European companies and the ESA. Landsat, with its widely dispersed technology and data, has encouraged international access to its capabilities and start-up of follow-on programs in other countries. Space station planning is proceeding with a view to worldwide utilization of space and to the commitment and resources other nations are willing to place in the station. It is conceded that administrative difficulties will arise if the space station is a completely international effort guided by NASA. Additionally, concern will be present for technology leaks, national security implications on the space station, and reasonably fulfilling the benefits expected by those who become partners in the construction and operation of the station.

  17. Technological Competitiveness of Ukraine under Conditions of a New Industrial Revolution and Development of Convergent Technologies

    Directory of Open Access Journals (Sweden)

    Matyushenko Igor Yu.


    Full Text Available The article considers the problem of increasing the technological competitiveness of Ukrainian enterprises under conditions of a new industrial revolution through the development and introduction of advanced converged technologies. The classification of industrial revolutions, namely, industrial, technological, information and Industry 4.0, is presented, and it has been determined that the key factor of the latter is cyber physical systems for introduction of the client-oriented “Internet of Things”. It has been justified that the formation of Industry 4.0 in developed countries will occur through advanced production technologies (APT, which main characteristics are technological substitution, automation, customization, localization and economic efficiency. It has been found that in 2020 the main priority APT will be: systems of production process control; multidimensional modeling of complex products; intelligent production systems and robotics; systems of creation and transformation (growing of material objects and 3D-printing; materials effective in creating perspective actuating devices (compositional and those that exhibit their properties in small-size structures. It has been proved that the recovery of Ukraine’s industry is not possible on the old industrial base, and the creation of a new industry based on APT of Industry 4.0 is possible in the following areas: ICT (primarily in the field of software development; new composite materials with specified properties; industrial nanobiotechnologies (biomedicine and pharmacy, new agricultural technologies; mathematical modeling for creation of intelligent production systems; space research and development (in particular, development of the first stages of heavy missiles. The necessity of elaborating state programs of competitiveness development on the basis of APT, foresight research oftechnology priorities, promoting high-tech exports in Ukraine has been substantiated.

  18. Space technology transfer to developing countries: opportunities and difficulties (United States)

    Leloglu, U. M.; Kocaoglan, E.

    Space technology, with its implications on science, economy and security, is mostly chosen as one of the priority areas for technological development by developing countries. Most nations aspiring to begin playing in the space league prefer technology transfer programs as a first step. Decreasing initial costs by small satellite technology made this affordable for many countries. However, there is a long way from this first step to establishment of a reliable space industry that can both survive in the long term with limited financial support from the government and meet national needs. This is especially difficult when major defense companies of industrialized countries are merging to sustain their competitiveness. The prerequisites for the success are implementation of a well-planned space program and existence of industrialization that can support basic testing and manufacturing activities and supply qualified manpower. In this study, the difficulties to be negotiated and the vicious circles to be broken for latecomers, that is, developing countries that invest on space technologies are discussed. Especially, difficulties in the technology transfer process itself, brain drain from developing countries to industrialized countries, strong competition from big space companies for domestic needs, costs of establishing and maintaining an infrastructure necessary for manufacturing and testing activities, and finally, the impact of export control will be emphasized. We will also try to address how and to what extent collaboration can solve or minimize these problems. In discussing the ideas mentioned above, lessons learned from the BILSAT Project, a technology transfer program from the UK, will be referred.

    Castro Galvan, A.; Marco Pelegrin, M.; Salve Galiana, R.; Vallejo Haya, J.; Tagle Gonzalez, J. A.


    R and D and, more recently, technological innovation and its relationship with competitivity are more and more part of conferences, books, articles and political speeches and very often are the central part of them. Innovation has become fashionable and many initiatives have come out in connection with it. However, the relationship between technological innovation and competitivity are not always obvious. The current article intends to illustrate some mechanisms that link these two concepts through a specific case, DTN, that is already providing results for the Spanish nuclear industry and whose example can be extrapolated to other industrial sectors. The importance given by the nuclear to the innovation, the research and the technological development it is not new either exclusively belong to any specific organisation but makes evident the coherence between its traditional approach and the current idea of modernizing the country promoting the national technological capacity.

    The rapidly increasing demand for greater speed and efficiency on the information superhighway requires significant improvements over conventional electronic logic circuits. Optical interconnections and optical integrated circuits are strong candidates to provide the way out of the extreme limitations imposed on the growth of speed and complexity of nowadays computations by the conventional electronic logic circuits. The new optical technology has increased the demand for high quality optical materials. NASA's recent involvement in processing optical materials in space has demonstrated that a new and unique class of high quality optical materials are processible in a microgravity environment. Microgravity processing can induce improved orders in these materials and could have a significant impact on the development of optical computers. We will discuss NASA's role in processing these materials and report on some of the associated nonlinear optical properties which are quite useful for optical computers technology.

  4. Struggle for Space: Viral Extinction through Competition for Cells (United States)

    Cuesta, José A.; Aguirre, Jacobo; Capitán, José A.; Manrubia, Susanna C.


    The design of protocols to suppress the propagation of viral infections is an enduring enterprise, especially hindered by limited knowledge of the mechanisms leading to viral extinction. Here we report on infection extinction due to intraspecific competition to infect susceptible hosts. Beneficial mutations increase the production of viral progeny, while the host cell may develop defenses against infection. For an unlimited number of host cells, a feedback runaway coevolution between host resistance and progeny production occurs. However, physical space limits the advantage that the virus obtains from increasing offspring numbers; thus, infection clearance may result from an increase in host defenses beyond a finite threshold. Our results might be relevant to devise improved control strategies in environments with mobility constraints or different geometrical properties.

  5. Final report: U.S. competitive position in automotive technologies

    Energy Technology Data Exchange (ETDEWEB)

    Albert, Michael B.; Cheney, Margaret; Thomas, Patrick; Kroll, Peter


    Patent data are presented and analyzed to assess the U.S. competitive position in eleven advanced automotive technology categories, including automotive fuel cells, hydrogen storage, advanced batteries, hybrid electric vehicles and others. Inventive activity in most of the technologies is found to be growing at a rapid pace, particularly in advanced batteries, automotive fuel cells and ultracapacitors. The U.S. is the clear leader in automotive fuel cells, on-board hydrogen storage and light weight materials. Japan leads in advanced batteries, hybrid electric vehicles, ultracapacitors, and appears to be close to overtaking the U.S. in other areas of power electronics.

  6. Virginia Space Grant Consortium Management of National General Aviation Design Competition (United States)


    This report summarizes the management of the National General Aviation Design Competition on behalf of NASA, the FAA and the Air Force by the Virginia Space Grant Consortium (VSGC) for the time period October 1, 2000 through September 30, 2001. This was the VSGC's seventh and final year of managing the Competition, which the Consortium originally designed, developed and implemented for NASA and the FAA. The competition is now being managed in-house by NASA. Awards to winning university teams were presented at a ceremony held at AirVenture 2001, the Experimental Aircraft Association's Annual Convention and Fly-In at Oshkosh, Wis. by NASA and FAA officials. The competition called for individuals or teams of undergraduate and graduate students from U.S. engineering schools to participate in a major national effort to rebuild the U.S. general aviation sector. Participants were challenged to meet the engineering goals of the Advanced General Aviation Transport Experiment (AGATE) project. For the purpose of the contest, general aviation aircraft are typically defined as single or twin engine (turbine or piston), single-pilot, fixed-wing aircraft for 2 - 6 passengers. The competition seeks to raise student awareness of the importance of general aviation by having students address design challenges for a small aircraft transportation system. NASA, AFRL and the FAA hope to stimulate breakthroughs in technology and their application in the general aviation marketplace. National goals for revitalizing the industry offer excellent, open-ended design challenges with real world applications for the Innovative Design Category. Both individual and team submissions were encouraged. University faculty advisors and students consistently cite the value of this kind of educational experience for their engineering students. Eight proposals were submitted for the 2001 Competition for the Innovative Design Category. Eleven faculty members and 124 students participated. Since inception

    Full Text Available It is well known that technology is a key factor for the economic progress and helps countries competing more successfully in markets for new goods and services. Technological competitiveness becomes this way closely related to the degree of innovativeness of a country. Although there are several indicators that measure directly the innovativeness of a country, there are still problems at the moment related to the availability of data. In this paper, we decided to assess the technological competitiveness of countries, based on a structural decomposition analysis of the patent shares on the world market. Unlike other authors who applied this methodology in their studies, we collected our data from the World Intellectual Property Organization (WIPO Statistical Database, covering 12 years, from 2000 till 2011 and we took into consideration 35 technology subsectors in 33 countries (EU 27, China, Canada, Japan, US, Switzerland and Norway. This approach should highlight the countries’ technological opportunities on the world level and measure their access towards sectors with high technological opportunities. Structural decomposition analysis points out the extent to which the shifts between technological sectors were induced by the changing technological environment on the world level. The analysis also shows the extent to which a country has an advantage/disadvantage from its past specialization pattern, having had a priori patenting activities in sectors that are now offering high opportunities and the extent to which the country deliberately moved into high opportunity technology sectors, or at least out of the industries with declining opportunities. The outcomes showed that technological development of countries on the world market played an important role for the patenting activity, being highly related to a well-developed infrastructure and pointed out that there are still a lot of European countries facing problems related to the

    Hay, Jason; Gresham, Elaine; Mullins, Carie; Graham, Rachael; Williams-Byrd; Reeves, John D.


    Under the direction of NASA's Exploration Systems Mission Directorate (ESMD), Directorate Integration Office (DIO), The Tauri Group with NASA's Technology Assessment and Integration Team (TAIT) completed several studies and white papers that identify novel technologies for human exploration. These studies provide technical inputs to space exploration roadmaps, identify potential organizations for exploration partnerships, and detail crosscutting technologies that may meet some of NASA's critical needs. These studies are supported by a relational database of more than 400 externally funded technologies relevant to current exploration challenges. The identified technologies can be integrated into existing and developing roadmaps to leverage external resources, thereby reducing the cost of space exploration. This approach to identifying potential spin-in technologies and partnerships could apply to other national space programs, as well as international and multi-government activities. This paper highlights innovative technologies and potential partnerships from economic sectors that historically are less connected to space exploration. It includes breakthrough concepts that could have a significant impact on space exploration and discusses the role of breakthrough concepts in technology planning. Technologies and partnerships are from NASA's Technology Horizons and Technology Frontiers game-changing and breakthrough technology reports as well as the External Government Technology Dataset, briefly described in the paper. The paper highlights example novel technologies that could be spun-in from government and commercial sources, including virtual worlds, synthetic biology, and human augmentation. It will consider how these technologies can impact space exploration and will discuss ongoing activities for planning and preparing them.

  10. Preparing Ugandan Secondary Teachers for Robotics and Technology Competitions

    Directory of Open Access Journals (Sweden)

    Erdogan Kaya


    Full Text Available This paper describes the details of an intensive one-day robotics workshop designed to introduce the basics of educational robotics to 10 Ugandan secondary information technology teachers. At the end of the workshop, a survey was administered to the participating teachers. The workshop was successful in sparking teachers’ interest in robotics. Five out of 10 teachers participated in a regional robotics competition with their own school teams 5 months after participating in the workshop. The other 5 teachers planned to participate in the same regional robotics competition in the following year. This study suggests that robotics programs offer an opportunity for students in developing countries such as Uganda to become deeply involved in STEM activities and develop an interest in STEM careers. Further research might focus on teacher professional development that is a critical factor mediating students’ access to quality STEM education in developing countries.

    CERN Document Server

    Yodzis, Peter


    This volume is an investigation of interspecific competition for space, particularly among sessile organisms, both plant and animal, and its consequences for community structure. While my own contribu­ tion ----and the bulk of this volume --- lies in mathematical analysis of the phenomenon, I have also tried to summarize the most important natural historical aspects of these communities, and have devoted much effort to relating the mathematical results to observations of the natural world. Thus, the volume has both a synthetic and an analytic aspect. On the one hand, I have been struck by certain similarities among many communities, from forests to mussel beds, in which spatial com­ petition is important. On the other hand, I have analyzed this pheno­ menon by means of reaction-dispersal models. Finally, the mathematical analysis has suggested a conceptual framework for these communities which, I believe, further unifies and illuminates the field data. A focal perception of this work is that, just as niche...

    Nikanpour, Darius; Jiang, Xin Xiang; Goroshin, Samuel; Haddad, Emile; Kruzelecky, Roman; Hoa, Suong; Merle, Philippe; Kleiman, Jacob; Gendron, Stephane; Higgins, Andrew; Jamroz, Wes

    The space environment, and in particular the Low Earth Orbit (LEO), is becoming increasingly populated with space debris which include fragments of dysfunctional spacecraft parts and materials traveling at speeds up to 15 km per second. These pose an escalating potential threat to LEO spacecraft, the international space station, and manned missions. This paper presents the Canadian activities to address the concerns over space debris in terms of debris mitigation measures and technologies; these include novel spacecraft demise technologies to safely decommission the spacecraft at the end of the mission, integrated self-healing material technologies for spacecraft structures to facilitate self-repair and help maintain the spacecraft structural and thermal performance, hypervelocity ground test capability to predict the impact of space debris on spacecraft performance, and ways of raising awareness within the space community through participation in targeted Science and Technology conferences and international forums.

    This survey describes brine drying technologies that have been developed for use in space and industry. NASA has long considered developing a brine drying system for the International Space Station (ISS). Possible processes include conduction drying in many forms, spray drying, distillation, freezing and freeze drying, membrane filtration, and electrical processes. Commercial processes use similar technologies. Some proposed space systems combine several approaches. The current most promising candidates for use on the ISS use either conduction drying with membrane filtration or spray drying.

    Berman, Joshua; Berman, Timothy; Billheimer, Thomas; Biclmer. Elizabeth; Hood, Stuart; Neas, Charles


    CanSat is an international student design-build-launch competition organized by the American Astronautical Society (AAS) and American Institute of Aeronautics and Astronautics (AIAA). The competition is also sponsored by the Naval Research Laboratory (NRL) and the National Aeronautics and Space Administration (NASA). The CanSat competition is designed for college, university and high school students wanting to participate in an applicable space-related competition. The objective of the CanSat competition is to complete space exploration missions by designing a specific system for a small sounding rocket payload which will follow and perform to a specific set of rules and guidelines for each year's competition. The competition encompasses a complete life-cycle of one year which includes all phases of design, integration, testing, judging and competition. The mission guidelines are based from space exploration missions and include bonus requirement options which teams may choose to participate in. The fundamental goal of the competition is to educate future engineers and scientists. This is accomplished by students applying systems engineering practices to a development project that incorporates an end-to-end life cycle, from requirements analysis, through preliminary design, integration and testing, an actual flight of the CanSat, and concluding with a post-mission debrief. This is done specifically with space related missions to bring a unique aspect of engineering and design to the competition. The competition has been progressing since its creation in 2005. The competition was originally meant to purely convey the engineering and design process to its participants, but through many experiences the competition has also undergone a learning experience with respect to systems engineering process and design.

  17. The Space House TM : Space Technologies in Architectural Design (United States)

    Gampe, F.; Raitt, D.


    The word "space" has always been associated with and had a profound impact upon architectural design. Until relatively recently, however, the term has been used in a different sense to that understood by the aerospace community - for them, space was less abstract, more concrete and used in the context of space flight and space exploration, rather than, say, an empty area or space requiring to be filled by furniture. However, the two senses of the word space have now converged to some extent. Interior designers and architects have been involved in designing the interior of Skylab, the structure of the International Space Station, and futuristic space hotels. Today, architects are designing, and builders are building, houses, offices and other structures which incorporate a plethora of new technologies, materials and production processes in an effort not only to introduce innovative and adventurous ideas but also in an attempt to address environmental and social issues. Foremost among these new technologies and materials being considered today are those that have been developed for and by the space industry. This paper examines some of these space technologies, such as energy efficient solar cells, durable plastics, air and water filtration techniques, which have been adapted to both provide power while reducing energy consumption, conserve resources and so on. Several of these technologies have now been employed by the European Space Agency to develop a Space House TM - the first of its kind, which will be deployed not so much on planets like Mars, but rather here on Earth. The Space House TM, which exhibits many innovative features such as high strength light-weight carbon composites, active noise-damped, (glass and plastic) windows, low-cost solar arrays and latent heat storage, air and water purification systems will be described.

  18. Electricity to natural gas competition under customer-side technological change: a marginal cost pricing analysis

    International Nuclear Information System (INIS)

    Gulli', Francesco


    This paper aims at evaluating the impact of technological change (on the customer side of the meter) on the network energy industry (electricity and natural gas). The performances of the small gas fired power technologies and the electrical reversible heat pumps have improved remarkably over the last ten years, making possible (or more viable) two opposite technological trajectories: the fully gas-based system, based on the use of small CHP (combined heat and power generation) plants, which would involve a wide decentralisation of energy supply; the fully electric-based system, based on the use of reversible electric heat pumps, which would imply increasing centralisation of energy supply. The analysis described in this paper attempts to evaluate how these two kinds of technological solutions can impact on inter-service competition when input prices are ste equals to marginal costs of supply in each stage of the electricity and natural gas industries. For this purpose, unbundled prices over time and over space are simulated. In particular the paper shows that unbundling prices over space in not very important in affecting electricity to natural gas competition and that, when prices are set equal to long-run marginal costs, the fully electric-based solution (the reversible heat pump) is by far preferable to the fully gas-based solution (the CHP gas fired small power plant). In consequence, the first best outcome of the technological change would involve increasing large power generation and imported (from the utility grid) electricity consumption. Given this framework, we have to ask ourselves why operators, regulators and legislators are so optimistic about the development of the fully gas-based solutions. In this respect, the paper suggests that market distortions (such as market power, energy taxation and inefficient pricing regulation) might have give an ambiguous representation of the optimal technological trajectory, inducing to overestimate the social value

  19. Competitiveness through cooperation between electricity and information technology. TESLA - Information technology and electric power systems technology programme 1998-2002

    Energy Technology Data Exchange (ETDEWEB)



    The electricity markets are being opened up to competition all round the world. To succeed in competition electricity sellers want new information technology tools to use in managing the sale of electricity. The network companies are aiming to step up utilization of their distribution capacity and to optimize power quality and the reliability of supply. Consumers need solutions with which they can manage their own power consumption and tendering sellers. The Nordic countries have been the first to deregulate their electricity markets. This head start in time is being made use of to generate a head start in technology. Tekes has initiated a technology programme for the years 1998 to 2002, named TESLA - Information Technology and Electric Power Systems, to promote the competitiveness of the Finnish electricity industry in changing conditions. The objective of the programme is to adapt information technology extensively to power distribution and thus develop the potential for Finland`s electricity industry to succeed on world markets.

  2. Technology roadmapping: The integration of strategic and technology planning for competitiveness

    Energy Technology Data Exchange (ETDEWEB)

    Bray, O.H.; Garcia, M.L.


    Technology roadmapping is a form of technology planning that can help organizations deal with an increasingly competitive environment. As a DOE laboratory with R&D as a major product, Sandia must do effective technology planning to identify and develop technologies required to meet its mission. Once technology enhancements or new technologies are identified, they may be developed internally or collaboratively with external partners. For either approach, technology roadmapping is an effective tool for technology planning and coordination, which fits within a broader set of planning activities. Potential benefits of roadmapping include identifying critical technologies and gaps, coordination of research activities, and improved marketing information. Roadmapping is particularly useful when investment decisions are not straightforward and for coordinating the development of multiple technologies, especially across multiple projects. This paper formalizes and documents the technology roadmapping process. It describes the process and shows how it fits within an overall strategic and technology planning process. The technology roadmapping process consists of three phases: preliminary activity, development of the roadmap, and followup activity. Preliminary activity includes: satisfy essential conditions, provide leadership/sponsorship, and define the scope and boundaries for the roadmap. Development of the technology roadmap includes: (1) Identify the {open_quotes}product{close_quotes} that will be the focus of the roadmap. (2) Identify the critical system requirements and their targets. (3) Specify the major technology areas. (4) Specify the technology drivers and their targets. (5) Identify technology alternatives and their time lines. (6) Recommend the technology alternatives that should be pursued. (7) Create the technology roadmap report. Follow-up activity includes: (1) Critique and validate the roadmap. (2) Develop an implementation plan. (3) Review and update.

  5. Fostering research aptitude among high school students through space weather competition (United States)

    Abdullah, M.; Majid, R. A.; Bais, B.; Bahri, N. S.; Asillam, M. F.


    Cultivating research culture at an early stage is important for capacity building in a community. The high school level is the appropriate stage for research to be introduced because of students' competitive nature. Participation in the space weather competition is one of the ways in which research aptitude can be fostered in high school students in Malaysia. Accordingly, this paper presents how research elements were introduced to the students at the high school level through their participation in the space weather competition. The competition required the students to build a system to detect the presence of solar flares by utilizing VLF signals reflected from the ionosphere. The space weather competition started off with proposal writing for the space weather related project where the students were required to execute extensive literature review on the given topic. Additionally, the students were also required to conduct the experiments and analyse the data. Results obtained from data analysis were then validated by the students through various other observations that they had to carry out. At the end of the competition, students were expected to write a comprehensive technical report. Through this competition, the students learnt how to conduct research in accordance to the guidelines provided through the step by step approach exposed to them. Ultimately, this project revealed that the students were able to conduct research on their own with minimal guidance and that participation in the competition not only generated enjoyment in learning but also their interest in science and research.

And we categorized 48 sectors into some technological levelsThe purpose of this paper is to explore empirically whether export competitiveness of Korea and Japan has changed since 1990s. Unlike existing literature, we tried to grasp changing patterns of export competitiveness by new methodology such as belonging quadrant and moving direction, rather than simply showing its trend or comparison classified by industry. And we categorized 48 sectors into some technological levels, then analyzed how the change of export competitiveness is distributed by each technological level. When seeing 'revealed comparative advantage' and 'trade specification index', we found considerable changes in export competitiveness. Competitiveness of Korea has rapidly improved while that of Japan has been continuously decreasing. Especially the gap of competitiveness between Korea and Japan has largely reduced around the midterm of 2000s. Shrinking of the gap in export competitiveness has begun from the latter half of 1990s and first half of 2000s. Change of export competitiveness shows different trend by technology level. Korea has gained more competitiveness than Japan in high and middle level of technology. Korea shows upward tendency of competitiveness in mid and high technology, while Japan in low technology. Competitiveness gap between Korea and Japan is rapidly decreasing since the late 1990s, and curtailment of the gap is mainly happening in the high level of technological capabilities.

  11. Strategic Technologies for Deep Space Transport (United States)

    Litchford, Ronald J.


    Deep space transportation capability for science and exploration is fundamentally limited by available propulsion technologies. Traditional chemical systems are performance plateaued and require enormous Initial Mass in Low Earth Orbit (IMLEO) whereas solar electric propulsion systems are power limited and unable to execute rapid transits. Nuclear based propulsion and alternative energetic methods, on the other hand, represent potential avenues, perhaps the only viable avenues, to high specific power space transport evincing reduced trip time, reduced IMLEO, and expanded deep space reach. Here, key deep space transport mission capability objectives are reviewed in relation to STMD technology portfolio needs, and the advanced propulsion technology solution landscape is examined including open questions, technical challenges, and developmental prospects. Options for potential future investment across the full compliment of STMD programs are presented based on an informed awareness of complimentary activities in industry, academia, OGAs, and NASA mission directorates.

  13. Science, technology, environment, and competitiveness in a North American context

    Energy Technology Data Exchange (ETDEWEB)

    Trocki, L.K.


    Most economic activities pollute. Environmental regulations should serve the public good by providing incentives to reduce pollution caused by economic activity. Economic incentives include pollution taxes, subsidies for pollution abatement, and tradeable permits or allowances to pollute. Because of the political unacceptability of taxes and permits, much regulation imposes command and control measures and provides less incentive to minimize pollution. Efficient incentives would encourage pollution abatement up to the point where the cost of abatement equals the social and private benefit from the improvements in the environment. While these costs and benefits are difficult to measure, many analysts contend that the way environmental laws have been formulated and implemented in the US leads to very inefficient pollution control. This inefficiency can contribute to a decline in economic competitiveness in the long run, although economic studies do not support the ``pollution haven`` hypothesis. Better analysis (foresight) of the cost of transboundary pollution, significant in the Great Lakes region and along the US- Mexico border, as well as in rivers that flow between countries, is needed to formulate more effective policies and avoid sorry hindsight. Also, application of communal experience, technologies, and methods applied to shared problems can avoid costly duplication of searches for the optimal pollution abatement measures. 14 refs.

  14. Space power technology 21: Photovoltaics (United States)

    Wise, Joseph


    The Space Power needs for the 21st Century and the program in photovoltaics needed to achieve it are discussed. Workshops were conducted in eight different power disciplines involving industry and other government agencies. The Photovoltaics Workshop was conducted at Aerospace Corporation in June 1987. The major findings and recommended program from this workshop are discussed. The major finding is that a survivable solar power capability is needed in photovoltaics for critical Department of Defense missions including Air Force and Strategic Defense Initiative. The tasks needed to realize this capability are described in technical, not financial, terms. The second finding is the need for lightweight, moderately survivable planar solar arrays. High efficiency thin III-V solar cells can meet some of these requirements. Higher efficiency, longer life solar cells are needed for application to both future planar and concentrator arrays with usable life up to 10 years. Increasing threats are also anticipated and means for avoiding prolonged exposure, retraction, maneuvering and autonomous operation are discussed.

  15. Johnson Space Center Research and Technology Report (United States)

    Pido, Kelle; Davis, Henry L. (Technical Monitor)


    As the principle center for NASA's Human Exploration and Development of Space (HEDS) Enterprise, the Johnson Space Center (JSC) leads NASA's development of human spacecraft, human support systems, and human spacecraft operations. To implement this mission, JSC has focused on developing the infrastructure and partnerships that enable the technology development for future NASA programs. In our efforts to develop key technologies, we have found that collaborative relationships with private industry and academia strengthen our capabilities, infuse innovative ideas, and provide alternative applications for our development projects. The American public has entrusted NASA with the responsibility for space--technology development, and JSC is committed to the transfer of the technologies that we develop to the private sector for further development and application. It is our belief that commercialization of NASA technologies benefits both American industry and NASA through technology innovation and continued partnering. To this end, we present the 1998-1999 JSC Research and Technology Report. As your guide to the current JSC technologies, this report showcases the projects in work at JSC that may be of interest to U.S. industry, academia, and other government agencies (federal, state, and local). For each project, potential alternative uses and commercial applications are described.

    This article investigates whether firms react to a radical technological substitution threat by a deliberate acceleration of innovation in their existing technology - the 'sailing ship effect'. It has been argued that the effect is both significant and widespread and warrants a reexamination of our...... assumptions about the working of the competitive process (Rosenberg 1972). Reexamination of two cases thought to be exemplars of the effect shows that it existed in neither. It is argued that if the phenomenon occurs, it is likely to be rare...

  17. ESA Technologies for Space Debris Remediation (United States)

    Wormnes, K.; Le Letty, R.; Summerer, L.; Schonenborg, R.; Dubois-Matra, O.; Luraschi, E.; Cropp, A.; Krag, H.; Delaval, J.


    Space debris is an existing and growing problem for space operations. Studies show that for a continued use of LEO, 5 - 10 large and strategically chosen debris need to be removed every year. The European Space Agency (ESA) is actively pursuing technologies and systems for space debris removal under its Clean Space initiative. This overview paper describes the activities that are currently ongoing at ESA and that have already been completed. Additionally it outlines the plan for the near future. The technologies under study fall in two main categories corresponding to whether a pushing or a pulling manoeuvre is required for the de-orbitation. ESA is studying the option of using a tethered capture system for controlled de-orbitation through pulling where the capture is performed using throw-nets or alternatively a harpoon. The Agency is also studying rigid capture systems with a particular emphasis on tentacles (potentially combined with a robotic arm). Here the de-orbitation is achieved through a push-manoeuvre. Additionally, a number of activities will be discussed that are ongoing to develop supporting technologies for these scenarios, or to develop systems for de-orbiting debris that can be allowed to re-enter in an uncontrolled manner. The short term goal and main driver for the current technology developments is to achieve sufficient TRL on required technologies to support a potential de-orbitation mission to remove a large and strategically chosen piece of debris.

  18. Technology transfer trends in Indian space programme (United States)

    Sridhara Murthi, K. R.; Shoba, T. S.


    Indian space programme, whose objectives involve acceleration of economic and social development through applications of space technology, has been engaged in the development of state-of-the-art satellite systems, launch vehicles and equipment necessary for applications. Even during the early phase of evolution of this Programme, deliberate policies have been adopted by the national space agency, namely, Indian Space Research Organisation (ISRO), to promote spin-off benefit from the technologies developed for the use of space projects. Consistently adhering to this policy, ISRO has transferred over 280 technologies till date, spanning a wide spectrum of disciplines. This has resulted in a fruitful two-way cooperation between a number of SMEs and the ISRO. In order to make the technology transfer process effective, ISRO has adopted a variety of functional and organizational policies that included awareness building measures, licensee selection methods, innovative contract systems, diverse transfer processes, post licencing services and feedback mechanisms. Besides analyzing these policies and their evolution, the paper discusses various models adopted for technology transfer and their impact on assessment. It also touches upon relevant issues relating to creating interface between public funded R&D and the private commercial enterprises. It suggests few models in which international cooperation could be pursued in this field.

  19. Space Biosensor Systems: Implications for Technology Transfer (United States)

    Hines, J. W.; Somps, C. J.; Madou, M.; Imprescia, Clifford C. (Technical Monitor)


    To meet the need for continuous, automated monitoring of animal subjects, including; humans, during space flight, NASA is developing advanced physiologic sensor and biotelemetry system technologies. The ability to continuously track basic physiological parameters, such as heart rate, blood pH, and body temperature, in untethered subjects in space is a challenging task. At NASA's Ames Research Center, where a key focus is gravitational biology research, engineers have teamed with life scientists to develop wireless sensor systems for automated physiologic monitoring of animal models as small as the rat. This technology is also being adapted, in collaboration with medical professionals, to meet human clinical monitoring needs both in space and on the ground. Thus, these advanced monitoring technologies have important dual-use functions; they meet space flight data collection requirements and constraints, while concurrently addressing a number of monitoring and data acquisition challenges on the ground in areas of clinical monitoring and biomedical research. Additional applications for these and related technologies are being sought and additional partnerships established that enhance development efforts, reduce costs and facilitate technology infusion between the public and private sectors. This paper describes technology transfer and co-development projects that have evolved out of NASA's miniaturized, implantable chemical sensor development efforts.

  6. UWB Technology and Applications on Space Exploration (United States)

    Ngo, Phong; Phan, Chau; Gross, Julia; Dusl, John; Ni, Jianjun; Rafford, Melinda


    Ultra-wideband (UWB), also known as impulse or carrier-free radio technology, is one promising new technology. In February 2002, the Federal Communications Commission (FCC) approved the deployment of this technology. It is increasingly recognized that UWB technology holds great potential to provide significant benefits in many terrestrial and space applications such as precise positioning/tracking and high data rate mobile wireless communications. This talk presents an introduction to UWB technology and some applications on space exploration. UWB is characterized by several uniquely attractive features, such as low impact on other RF systems due to its extremely low power spectral densities, immunity to interference from narrow band RF systems due to its ultra-wide bandwidth, multipath immunity to fading due to ample multipath diversity, capable of precise positioning due to fine time resolution, capable of high data rate multi-channel performance. The related FCC regulations, IEEE standardization efforts and industry activities also will be addressed in this talk. For space applications, some projects currently under development at NASA Johnson Space Center will be introduced. These include the UWB integrated communication and tracking system for Lunar/Mars rover and astronauts, UWB-RFID ISS inventory tracking, and UWB-TDOA close-in high resolution tracking for potential applications on robonaut.

  8. Nonproliferation Challenges in Space Defense Technology - PANEL (United States)

    Houts, Michael G.


    The use of highly enriched uranium (HEU) almost always "helps" space fission systems. Nuclear Thermal Propulsion (NTP) and high power fission electric systems appear able to use < 20% enriched uranium with minimal / acceptable performance impacts. However, lower power, "entry level" systems may be needed for space fission technology to be developed and utilized. Low power (i.e. approx.1 kWe) fission systems may have an unacceptable performance penalty if LEU is used instead of HEU. Are there Ways to Support Non-Proliferation Objectives While Simultaneously Helping Enable the Development and Utilization of Modern Space Fission Power and Propulsion Systems?

    L. A. Tsvetkova


    Full Text Available The analysis of prospects of introduction of the developments related to blokcheyn in the world and in Russia has been made. Key investors and beneficiaries in the development of blockchain technologies were identified. High competitiveness of Russian developments, unique staffing, and favorable climatic conditions for the development of blockade technologies in the Russian Federation were noted. The patent activity in the world has been analyzed and the place of Russia on the patent landscape in the field of blockchain technologies has been determined. It is shown that, to date, the weak position of Russian developers in the global patent landscape in the field of blockchain is not critical due to the high level of uncertainty in matters of protectability of the proposed blockchain algorithms. Special attention was paid to the delayed, perhaps shortterm, readiness of residents of industrially developed countries to expand in the global space of intellectual property associated with the blockchain as soon as the patentability of the proposed solutions is proved. It is concluded that the next 2–3 years should be considered as a “window of opportunity” to form the prerequisites for Russia’s technological leadership in the cluster of block-technologies.

    Balint, Tibor S.; Stevens, John


    Technological innovation is key to enable future space exploration missions at NASA. Technology development, however, is not only driven by performance and resource considerations, but also by a broad range of directly or loosely interconnected factors. These include, among others, strategy, policy and politics at various levels, tactics and programmatics, interactions between stakeholders, resource requirements, performance goals from component to system level, mission infusion targets, portfolio execution and tracking, and technology push or mission pull. Furthermore, at NASA, these influences occur on varying timescales and at diverse geographic locations. Such a complex and interconnected system could impede space technology innovation in this examined segment of the government environment. Hence, understanding the process through NASA's Planning, Programming, Budget and Execution cycle could benefit strategic thinking, planning and execution. Insights could be gained through suitable models, for example assessing the key drivers against the framework of Wicked Problems. This paper discusses NASA specific space technology innovation and innovation barriers in the government environment through the characteristics of Wicked Problems; that is, they do not have right or wrong solutions, only improved outcomes that can be reached through authoritative, competitive, or collaborative means. We will also augment the Wicked Problems model to account for the temporally and spatially coupled, and cyclical nature of this NASA specific case, and propose how appropriate models could improve understanding of the key influencing factors. In turn, such understanding may subsequently lead to reducing innovation barriers, and stimulating technology innovation at NASA. Furthermore, our approach can be adopted for other government-directed environments to gain insights into their structures, hierarchies, operational flow, and interconnections to facilitate circular dialogs towards

    CERN Document Server

    Choudhury, Balamati; Jha, Rakesh Mohan


    This book explores the terahertz antenna technology towards implementation of compact, consistent and cheap terahertz sources, as well as the high sensitivity terahertz detectors. The terahertz EM band provides a transition between the electronic and the photonic regions thus adopting important characteristics from these regimes. These characteristics, along with the progress in semiconductor technology, have enabled researchers to exploit hitherto unexplored domains including satellite communication, bio-medical imaging, and security systems. The advances in new materials and nanostructures such as graphene will be helpful in miniaturization of antenna technology while simultaneously maintaining the desired output levels. Terahertz antenna characterization of bandwidth, impedance, polarization, etc. has not yet been methodically structured and it continues to be a major research challenge. This book addresses these issues besides including the advances of terahertz technology in space applications worldwide,...

  7. The Space Technology 5 Avionics System (United States)

    Speer, Dave; Jackson, George; Stewart, Karen; Hernandez-Pellerano, Amri


    The Space Technology 5 (ST5) mission is a NASA New Millennium Program project that will validate new technologies for future space science missions and demonstrate the feasibility of building launching and operating multiple, miniature spacecraft that can collect research-quality in-situ science measurements. The three satellites in the ST5 constellation will be launched into a sun-synchronous Earth orbit in early 2006. ST5 fits into the 25-kilogram and 24-watt class of very small but fully capable spacecraft. The new technologies and design concepts for a compact power and command and data handling (C&DH) avionics system are presented. The 2-card ST5 avionics design incorporates new technology components while being tightly constrained in mass, power and volume. In order to hold down the mass and volume, and quali& new technologies for fUture use in space, high efficiency triple-junction solar cells and a lithium-ion battery were baselined into the power system design. The flight computer is co-located with the power system electronics in an integral spacecraft structural enclosure called the card cage assembly. The flight computer has a full set of uplink, downlink and solid-state recording capabilities, and it implements a new CMOS Ultra-Low Power Radiation Tolerant logic technology. There were a number of challenges imposed by the ST5 mission. Specifically, designing a micro-sat class spacecraft demanded that minimizing mass, volume and power dissipation would drive the overall design. The result is a very streamlined approach, while striving to maintain a high level of capability, The mission's radiation requirements, along with the low voltage DC power distribution, limited the selection of analog parts that can operate within these constraints. The challenge of qualifying new technology components for the space environment within a short development schedule was another hurdle. The mission requirements also demanded magnetic cleanliness in order to reduce

  8. Maturing Technologies for Stirling Space Power Generation (United States)

    Wilson, Scott D.; Nowlin, Brentley C.; Dobbs, Michael W.; Schmitz, Paul C.; Huth, James


    Stirling Radioisotope Power Systems (RPS) are being developed as an option to provide power on future space science missions where robotic spacecraft will orbit, flyby, land or rove. A Stirling Radioisotope Generator (SRG) could offer space missions a more efficient power system that uses one fourth of the nuclear fuel and decreases the thermal footprint of the current state of the art. The RPS Program Office, working in collaboration with the U.S. Department of Energy (DOE), manages projects to develop thermoelectric and dynamic power systems, including Stirling Radioisotope Generators (SRGs). The Stirling Cycle Technology Development (SCTD) Project, located at Glenn Research Center (GRC), is developing Stirling-based subsystems, including convertors and controllers. The SCTD Project also performs research that focuses on a wide variety of objectives, including increasing convertor temperature capability to enable new environments, improving system reliability or fault tolerance, reducing mass or size, and developing advanced concepts that are mission enabling. Research activity includes maturing subsystems, assemblies, and components to prepare them for infusion into future convertor and generator designs. The status of several technology development efforts are described here. As part of the maturation process, technologies are assessed for readiness in higher-level subsystems. To assess the readiness level of the Dual Convertor Controller (DCC), a Technology Readiness Assessment (TRA) was performed and the process and results are shown. Stirling technology research is being performed by the SCTD Project for NASA's RPS Program Office, where tasks focus on maturation of Stirling-based systems and subsystems for future space science missions.

  12. Space solar cell technology development - A perspective (United States)

    Scott-Monck, J.


    The developmental history of photovoltaics is examined as a basis for predicting further advances to the year 2000. Transistor technology was the precursor of solar cell development. Terrestrial cells were modified for space through changes in geometry and size, as well as the use of Ag-Ti contacts and manufacture of a p-type base. The violet cell was produced for Comsat, and involved shallow junctions, new contacts, and an enhanced antireflection coating for better radiation tolerance. The driving force was the desire by private companies to reduce cost and weight for commercial satellite power supplies. Liquid phase epitaxial (LPE) GaAs cells are the latest advancement, having a 4 sq cm area and increased efficiency. GaAs cells are expected to be flight ready in the 1980s. Testing is still necessary to verify production techniques and the resistance to electron and photon damage. Research will continue in CVD cell technology, new panel technology, and ultrathin Si cells.

  13. Space Launch System Upper Stage Technology Assessment (United States)

    Holladay, Jon; Hampton, Bryan; Monk, Timothy


    The Space Launch System (SLS) is envisioned as a heavy-lift vehicle that will provide the foundation for future beyond low-Earth orbit (LEO) exploration missions. Previous studies have been performed to determine the optimal configuration for the SLS and the applicability of commercial off-the-shelf in-space stages for Earth departure. Currently NASA is analyzing the concept of a Dual Use Upper Stage (DUUS) that will provide LEO insertion and Earth departure burns. This paper will explore candidate in-space stages based on the DUUS design for a wide range of beyond LEO missions. Mission payloads will range from small robotic systems up to human systems with deep space habitats and landers. Mission destinations will include cislunar space, Mars, Jupiter, and Saturn. Given these wide-ranging mission objectives, a vehicle-sizing tool has been developed to determine the size of an Earth departure stage based on the mission objectives. The tool calculates masses for all the major subsystems of the vehicle including propellant loads, avionics, power, engines, main propulsion system components, tanks, pressurization system and gases, primary structural elements, and secondary structural elements. The tool uses an iterative sizing algorithm to determine the resulting mass of the stage. Any input into one of the subsystem sizing routines or the mission parameters can be treated as a parametric sweep or as a distribution for use in Monte Carlo analysis. Taking these factors together allows for multi-variable, coupled analysis runs. To increase confidence in the tool, the results have been verified against two point-of-departure designs of the DUUS. The tool has also been verified against Apollo moon mission elements and other manned space systems. This paper will focus on trading key propulsion technologies including chemical, Nuclear Thermal Propulsion (NTP), and Solar Electric Propulsion (SEP). All of the key performance inputs and relationships will be presented and

  14. An Exercise in Technology Prioritization in a Competitive Environment (United States)

    Stephens, Karen L.


    The proper prioritization of technologies within a technology development program is critical for success in a budget constrained environment. A large portfolio of diverse products at differing states of development all competing for program resources presents a need for a process by which a realistic need date can guide the development strategy for each technology. This paper will document an exercise to identify "mission pull" for each technology that can be used to identify the best projected need date for each. This date is then used to back out a development schedule with corresponding funding profile needed to meet the flight opportunity.

  16. Biodiversity patterns from an individual-based competition model on niche and physical spaces

    International Nuclear Information System (INIS)

    Fort, H; Inchausti, P


    We formulate a microscopic (individual-based and spatially explicit) ecological model to assess whether key patterns of community structure, species-packing and the spatial distribution of species are robust to relaxing the mean-field approximation made in classical ecological models. In this model of community dynamics species compete both locally in physical space and along a niche axis and it includes just two free parameters, σ, controlling the extent of competition in niche space, and t, the simulation time. This minimalistic model (1) reproduces with considerable accuracy the dynamic sequence of relative species abundances, biodiversity indices and species–area relationships that are empirically found in censuses of trees in a well-studied tropical forest; (2) shows that the clumpy pattern of niches leading to long-lasting species coexistence obtained by classical competition models is robust to relaxing the mean-field assumption. Nevertheless species that are clumped in niche space are simultaneously spatially segregated

    Bacai, Hina; Zolotikova, Svetlana; Young, Mandy; Cowsill, Rhys; Wells, Alan; Monks, Paul; Archibald, Alexandra; Smith, Teresa


    Earth Observation data and remote sensing technologies have been maturing into useful tools that can be utilised by local authorities and businesses to aid in activates such as monitoring climate change trends and managing agricultural land and water uses. The European Earth observation programme Copernicus, previously known as GMES (Global Monitoring for Environment and Security), provides the means to collect and process multi-source EO and environmental data that supports policy developments at the European level. At the regional and local level, the Copernicus programme has been initiated through Regional Contact Office (RCO), which provide knowledge, training, and access to expertise both locally and at a European level through the network of RCOs established across Europe in the DORIS_Net (Downstream Observatory organised by Regions active In Space - Network) project (Grant Agreement No. 262789 Coordination and support action (Coordinating) FP7 SPA.2010.1.1-07 "Fostering downstream activities and links with regions"). In the East Midlands UK RCO, educational and training workshops and modules have been organised to highlight the wider range of tools and application available to businesses and local authorities in the region. Engagement with businesses and LRA highlighted the need to have a tiered system of training to build awareness prior to investigating innovative solutions and space technology uses for societal benefits. In this paper we outline education and training programmes which have been developed at G-STEP (GMES - Science and Technology Education Partnership), University of Leicester, UK to open up the Copernicus programme through the Regional Contact Office to downstream users such as local businesses and LRAs. Innovative methods to introduce the operational uses of Space technologies in real cases through e-learning modules and web-based tools will be described and examples of good practice for educational training in these sectors will be

    Krishen, Kumar


    The Small Business Innovation Research (SBIR) Program increases opportunities for small businesses to participate in research and development (R&D), increases employment, and improves U.S. competitiveness. Specifically the program stimulates U.S. technological innovation by using small businesses to meet federal R&D needs, increasing private-sector commercialization of innovations derived from federal R&D, and fostering and encouraging the participation of socially disadvantaged businesses. In 2000, the Small Business Technology Transfer (STTR) Program extended and strengthened the SBIR Program, increasing its emphasis on pursuing commercial applications by awarding contracts to small business concerns for cooperative R&D with a nonprofit research institution. Modeled after the SBIR Program, STTR is nevertheless a separately funded activity. Technologies that have resulted from the Johnson Space Center SBIR STTR Program include: a device for regenerating iodinated resin beds; laser-assisted in-situ keratomileusis or LASIK; a miniature physiological monitoring device capable of collecting and analyzing a multitude of real-time signals to transmit medical data from remote locations to medical centers for diagnosis and intervention; a new thermal management system for fibers and fabrics giving rise to new line of garments and thermal-enhancing environments; and a highly electropositive material that attracts and retains electronegative particles in water.

    As it is more environmentally sound and friendly than conventional energy technologies that emit carbon dioxide, hydrogen technology can play a key role in solving the problems caused by the greenhouse gas effect and in coping with the hydrogen economy. Numerous countries around the world, including Korea, have increasingly focused on R and D where hydrogen technology development is concerned. This paper focuses on the use of the fuzzy analytic hierarchy process (fuzzy AHP), which is an extension of the AHP method and uses interval values to reflect the vagueness of human thought, to assess national competitiveness in the hydrogen technology sector. This analysis based on the AHP and fuzzy AHP methods revealed that Korea ranked 6th in terms of national competitiveness in the hydrogen technology sector. (author)

  20. Technology Area Roadmap for In-Space Propulsion Technologies (United States)

    Johnson, Les; Meyer, Michael; Palaszewski, Bryan; Coote, David; Goebel, Dan; White, Harold


    The exponential increase of launch system size.and cost.with delta-V makes missions that require large total impulse cost prohibitive. Led by NASA fs Marshall Space Flight Center, a team from government, industry, and academia has developed a flight demonstration mission concept of an integrated electrodynamic (ED) tethered satellite system called PROPEL: \\Propulsion using Electrodynamics.. The PROPEL Mission is focused on demonstrating a versatile configuration of an ED tether to overcome the limitations of the rocket equation, enable new classes of missions currently unaffordable or infeasible, and significantly advance the Technology Readiness Level (TRL) to an operational level. We are also focused on establishing a far deeper understanding of critical processes and technologies to be able to scale and improve tether systems in the future. Here, we provide an overview of the proposed PROPEL mission. One of the critical processes for efficient ED tether operation is the ability to inject current to and collect current from the ionosphere. Because the PROPEL mission is planned to have both boost and deboost capability using a single tether, the tether current must be capable of flowing in both directions and at levels well over 1 A. Given the greater mobility of electrons over that of ions, this generally requires that both ends of the ED tether system can both collect and emit electrons. For example, hollow cathode plasma contactors (HCPCs) generally are viewed as state-of-the-art and high TRL devices; however, for ED tether applications important questions remain of how efficiently they can operate as both electron collectors and emitters. Other technologies will be highlighted that are being investigated as possible alternatives to the HCPC such as Solex that generates a plasma cloud from a solid material (Teflon) and electron emission (only) technologies such as cold-cathode electron field emission or photo-electron beam generation (PEBG) techniques

  1. The impact of competitive bidding on the market prospects for renewable electric technologies

    Energy Technology Data Exchange (ETDEWEB)

    Swezey, B G


    This report examines issues regarding the ability of renewable-energy-based generation projects to compete fossil-fuel-based projects in competitive bidding solicitations. State and utility bidding results revealed that on a relative basis, utilities contract for less renewable-energy-based capacity under competitive bidding than under past methods of qualifying facility contracting. It was concluded that renewables are not being chosen more often under competitive bidding because it emphasizes price and operating considerations over other attributes of renewables, such as environmental considerations, fuel diversity, and fuel price stability. Examples are given of bidding approaches used by some states and utilities that have resulted in renewables-based projects winning generation bids. In addition, the appendix summarizes, by state, competitive bidding activities and results for supply-side solicitations that were open to all fuels and technologies.

  2. The Application of Intelligent Building Technologies to Space Hotels (United States)

    Fawkes, S.

    This paper reports that over the last few years Intelligent Building technologies have matured and standardised. It compares the functions of command and control systems in future large space facilities such as space hotels to those commonly found in Intelligent Buildings and looks at how Intelligent Building technologies may be applied to space hotels. Many of the functions required in space hotels are the same as those needed in terrestrial buildings. The adaptation of standardised, low cost, Intelligent Building technologies would reduce capital costs and ease development of future space hotels. Other aspects of Intelligent Buildings may also provide useful models for the development and operation of space hotels.

  4. China, the United States, and competition for resources that enable emerging technologies. (United States)

    Gulley, Andrew L; Nassar, Nedal T; Xun, Sean


    Historically, resource conflicts have often centered on fuel minerals (particularly oil). Future resource conflicts may, however, focus more on competition for nonfuel minerals that enable emerging technologies. Whether it is rhenium in jet engines, indium in flat panel displays, or gallium in smart phones, obscure elements empower smarter, smaller, and faster technologies, and nations seek stable supplies of these and other nonfuel minerals for their industries. No nation has all of the resources it needs domestically. International trade may lead to international competition for these resources if supplies are deemed at risk or insufficient to satisfy growing demand, especially for minerals used in technologies important to economic development and national security. Here, we compare the net import reliance of China and the United States to inform mineral resource competition and foreign supply risk. Our analysis indicates that China relies on imports for over half of its consumption for 19 of 42 nonfuel minerals, compared with 24 for the United States-11 of which are common to both. It is for these 11 nonfuel minerals that competition between the United States and China may become the most contentious, especially for those with highly concentrated production that prove irreplaceable in pivotal emerging technologies.

  10. Energy Storage Technology Development for Space Exploration (United States)

    Mercer, Carolyn R.; Jankovsky, Amy L.; Reid, Concha M.; Miller, Thomas B.; Hoberecht, Mark A.


    The National Aeronautics and Space Administration is developing battery and fuel cell technology to meet the expected energy storage needs of human exploration systems. Improving battery performance and safety for human missions enhances a number of exploration systems, including un-tethered extravehicular activity suits and transportation systems including landers and rovers. Similarly, improved fuel cell and electrolyzer systems can reduce mass and increase the reliability of electrical power, oxygen, and water generation for crewed vehicles, depots and outposts. To achieve this, NASA is developing non-flow-through proton-exchange-membrane fuel cell stacks, and electrolyzers coupled with low permeability membranes for high pressure operation. The primary advantage of this technology set is the reduction of ancillary parts in the balance-of-plant fewer pumps, separators and related components should result in fewer failure modes and hence a higher probability of achieving very reliable operation, and reduced parasitic power losses enable smaller reactant tanks and therefore systems with lower mass and volume. Key accomplishments over the past year include the fabrication and testing of several robust, small-scale non-flow-through fuel cell stacks that have demonstrated proof-of-concept. NASA is also developing advanced lithium-ion battery cells, targeting cell-level safety and very high specific energy and energy density. Key accomplishments include the development of silicon composite anodes, lithiatedmixed- metal-oxide cathodes, low-flammability electrolytes, and cell-incorporated safety devices that promise to substantially improve battery performance while providing a high level of safety.

  15. Investigating load management technology options: a survey of technologies and issues. Final report. [Competitive interrelationships of LM, conservation, and renewables

    Energy Technology Data Exchange (ETDEWEB)



    Load-management-technology options are commercially available and may be desirable in many utility-service areas. Energy-conservation and renewable-energy-supply technologies are also cost-effective in many applications and, where installed, may reduce the effectiveness and attractiveness of load-management options. Recent energy legislation has not addressed these competitive interrelationships; future legislation is unlikely to do so unless a coordinated task-force effort among relevant DOE offices is pursued to derive strategic technology and policy recommendations on this issue. R and D strategies should help formulate these recommendations.

    Petreleos de Venezuela (PDVSA) and its affiliated companies, aware of the importance of the technology to sustain the viability of a successful corporation in global markets with increasing competition and stringent economies, are devoting important efforts in technology as an effective tool to add competitiveness to its core businesses. These efforts are based in the conception of the technology as a structural aspect of the corporation integrated to each one of its businesses. In this sense technology is considered in an integrated way together with markets, operations, infrastructure, resources, etc., across the value chain of the company, from the conception of its vision and mission to the formulation and execution of its operating plans. In this presentation, the conceptual and methodological aspects employed by PDVSA in the establishment of its technology strategy integrated to its business plan, and subsequent project portfolio definition, are summarized. The experience acquired through this corporative exercise conducted by PDVSA confirms that technology and its management are highly linked to the culture of the companies and of the countries where they operate. The technology management best practices are very helpful in establishing processes and specific methodologies; however, the consideration of other aspects such as leadership, management style, shared values, etc., need to be taken into account with the same emphasis, in order to accomplish the changes needed to create a technology culture fitted to a given setting and ideology.

    Lyles, Garry M.


    The National Aeronautics and Space Administration's (NASA) Advanced Space Transportation Program is a customer driven, focused technology program that supports the NASA Strategic Plan and considers future commercial space business projections. The initial cycle of the Advanced Space Transportation Program implementation planning was conducted from December 1995 through February 1996 and represented increased NASA emphasis on broad base technology development with the goal of dramatic reductions in the cost of space transportation. The second planning cycle, conducted in January and February 1997, updated the program implementation plan based on changes in the external environment, increased maturity of advanced concept studies, and current technology assessments. The program has taken a business-like approach to technology development with a balanced portfolio of near, medium, and long-term strategic targets. Strategic targets are influenced by Earth science, space science, and exploration objectives as well as commercial space markets. Commercial space markets include those that would be enhanced by lower cost transportation as well as potential markets resulting in major increases in space business induced by reductions in transportation cost. The program plan addresses earth-to-orbit space launch, earth orbit operations and deep space systems. It also addresses all critical transportation system elements; including structures, thermal protection systems, propulsion, avionics, and operations. As these technologies are matured, integrated technology flight experiments such as the X-33 and X-34 flight demonstrator programs support near-term (one to five years) development or operational decisions. The Advanced Space Transportation Program and the flight demonstrator programs combine business planning, ground-based technology demonstrations and flight demonstrations that will permit industry and NASA to commit to revolutionary new space transportation systems

  8. HPCC technology awareness program: Improved economic competitiveness through technology awareness, transfer and application. Final report

    Energy Technology Data Exchange (ETDEWEB)


    A need has been defined by Congress for the DOE National Laboratories to participate in various dual use and technology transfer programs. This requirement has spawned several technology transfer approaches at the DOE laboratories. These programs are designed to encourage large and small business to bring their problems and needs forward, and to allow the labs to transfer effective high performance computing technology to the commercial marketplace. This IG Technologies grant from the DOE was undertaken to address the issues and problems associated with technology transfer between the DOE National Laboratories and commercial industry. The key focus is to gain an understanding of how DOE and industry independently and collectively view the requirements and the missing elements that could allow DOE to facilitate HPCC technology transfer. At issue is HPCC Technology Transfer for the High Performance Computing industry and its relationship to the DOE National Laboratories. Several observations on this are addressed. The issue of a ``Technology Utilization Gap`` between the National Laboratories and Independent Software Vendors is discussed. This study addressed the HPCC Technology Transfer plans of all six DOE National Labs. Study team members briefed numerous industrial users of HPCC technology as to the feasibility of technology transfer for various applications. Significant findings of the effort are that the resistance to technology transfer is much higher than anticipated for both the National Labs and industry. Also, HPCC Technology Transfer is observed to be a large company`s dominion. Small businesses have a difficult time in addressing the requirements of technology transfer using Cooperative Research and Development Agreements (CRADA`s). Large businesses and the DOE National Labs however, often have requirements and objectives which are at cross purposes, making effective technology transfer difficult.

    Full Text Available Today, in the era of knowledge economy a competitive advantage is based on technological development and innovation, as well as the exploitation of potential opportunities and possibilities for whose implementation knowledge is necessary. Constant investment in human capital increases productivity, employment and receives a direct source of innovation and longterm competitiveness. Human resources and their knowledge are the key to success for the economy and businesses, while incompetent workforce is one of the most important brake in their business. Development of competition in the domestic and international market, it became imperative for the development of a modern economy. In fact, knowledge is the capitalization of innovation through the creation of new products, services, processes, or labels, but that has no value and significance, if is not commercialized in the market. The aim of this paper is to show the level of competitiveness of the Serbian economy, measurable changes that occur in this direction and degree of easiness of doing business in Serbia, which should contribute to an increase in labor productivity.

  15. NASA Space Technology Roadmaps and Priorities: Restoring NASA's Technological Edge and Paving the Way for a New Era in Space (United States)


    Success in executing future NASA space missions will depend on advanced technology developments that should already be underway. It has been years since NASA has had a vigorous, broad-based program in advanced space technology development, and NASA's technology base is largely depleted. As noted in a recent National Research Council report on the U.S. civil space program: Future U.S. leadership in space requires a foundation of sustained technology advances that can enable the development of more capable, reliable, and lower-cost spacecraft and launch vehicles to achieve space program goals. A strong advanced technology development foundation is needed also to enhance technology readiness of new missions, mitigate their technological risks, improve the quality of cost estimates, and thereby contribute to better overall mission cost management. Yet financial support for this technology base has eroded over the years. The United States is now living on the innovation funded in the past and has an obligation to replenish this foundational element. NASA has developed a draft set of technology roadmaps to guide the development of space technologies under the leadership of the NASA Office of the Chief Technologist. The NRC appointed the Steering Committee for NASA Technology Roadmaps and six panels to evaluate the draft roadmaps, recommend improvements, and prioritize the technologies within each and among all of the technology areas as NASA finalizes the roadmaps.

    de Wit, Marc; Junginger, Martin; Faaij, Andre; Lensink, Sander; Londo, Marc


    A key aspect in modeling the (future) competition between biofuels is the way in which production cost developments are computed. The objective of this study was threefold: (i) to construct a (endogenous) relation between cost development and cumulative production (ii) to implement technological learning based on both engineering study insights and an experience curve approach, and (iii) to investigate the impact of different technological learning assumptions on the market diffusion patterns of different biofuels. The analysis was executed with the European biofuel model BioTrans, which computes the least cost biofuel route. The model meets an increasing demand, reaching a 25% share of biofuels of the overall European transport fuel demand by 2030. Results show that 1st generation biodiesel is the most cost competitive fuel, dominating the early market. With increasing demand, modestly productive oilseed crops become more expensive rapidly, providing opportunities for advanced biofuels to enter the market. While biodiesel supply typically remains steady until 2030, almost all additional yearly demands are delivered by advanced biofuels, supplying up to 60% of the market by 2030. Sensitivity analysis shows that (i) overall increasing investment costs favour biodiesel production, (ii) separate gasoline and diesel subtargets may diversify feedstock production and technology implementation, thus limiting the risk of failure and preventing lock-in and (iii) the moment of an advanced technology's commercial market introduction determines, to a large degree, its future chances for increasing market share.

    Tiger Liu, Jann-Yeng; Chen, hao-Yen; Lee, I.-Te


    The Ionospheric Radio Science Laboratory (IRSL) at Institute of Space Science, National Central University in Taiwan has been conducting a program for public outreach educations on space science by giving lectures, organizing camps, touring exhibits, and experiencing hand-on experiments to elementary school, high school, and college students as well as general public since 1991. The program began with a topic of traveling/living in space, and was followed by space environment, space mission, and space weather monitoring, etc. and a series of course module and experiment (i.e. experiencing activity) module was carried out. For past decadal, the course modules have been developed to cover the space environment of the Sun, interplanetary space, and geospace, as well as the space technology of the rocket, satellite, space shuttle (plane), space station, living in space, observing the Earth from space, and weather observation. Each course module highlights the current status and latest new finding as well as discusses 1-3 key/core issues/concepts and equip with 2-3 activity/experiment modules to make students more easily to understand the topics/issues. Regarding the space technologies, we focus on remote sensing of Earth's surface by FORMOSAT-2 and occultation sounding by FORMOSAT-3/COSMIC of Taiwan space mission. Moreover, scientific camps are given to lead students a better understanding and interesting on space sciences/ technologies. Currently, a visualized image projecting system, Dagik Earth, is developed to demonstrate the scientific results on a sphere together with the course modules. This system will dramatically improve the educational skill and increase interests of participators.

  1. Technology Development and Demonstration Concepts for the Space Elevator (United States)

    Smitherman, David V., Jr.


    During the 1990s several discoveries and advances in the development of carbon nano-tube (CNT) materials indicated that material strengths many times greater than common high-strength composite materials might be possible. Progress in the development of this material led to renewed interest in the space elevator concept for construction of a tether structure from the surface of the Earth through a geostationary orbit (GEO) and thus creating a new approach to Earth-to-orbit transportation infrastructures. To investigate this possibility the author, in 1999, managed for NASA a space elevator work:hop at the Marshall Space Flight Center to explore the potential feasibility of space elevators in the 21 century, and to identify the critical technologies and demonstration missions needed to make development of space elevators feasible. Since that time, a NASA Institute for Advanced Concepts (NIAC) funded study of the Space Elevator proposed a concept for a simpler first space elevator system using more near-term technologies. This paper will review some of the latest ideas for space elevator development, the critical technologies required, and some of the ideas proposed for demonstrating the feasibility for full-scale development of an Earth to GEO space elevator. Critical technologies include CNT composite materials, wireless power transmission, orbital object avoidance, and large-scale tether deployment and control systems. Numerous paths for technology demonstrations have been proposed utilizing ground experiments, air structures. LEO missions, the space shuttle, the international Space Station, GEO demonstration missions, demonstrations at the lunar L1 or L2 points, and other locations. In conclusion, this paper finds that the most critical technologies for an Earth to GEO space elevator include CNT composite materials development and object avoidance technologies; that lack of successful development of these technologies need not preclude continued development of

  17. Access from Space: A New Perspective on NASA's Space Transportation Technology Requirements and Opportunities (United States)

    Rasky, Daniel J.


    The need for robust and reliable access from space is clearly demonstrated by the recent loss of the Space Shuttle Columbia; as well as the NASA s goals to get the Shuttle re-flying and extend its life, build new vehicles for space access, produce successful robotic landers and s a q k retrr? llisrions, and maximize the science content of ambitious outer planets missions that contain nuclear reactors which must be safe for re-entry after possible launch aborts. The technology lynch pin of access from space is hypersonic entry systems such the thermal protection system, along with navigation, guidance and control (NG&C). But it also extends to descent and landing systems such as parachutes, airbags and their control systems. Current space access technology maturation programs such as NASA s Next Generation Launch Technology (NGLT) program or the In-Space Propulsion (ISP) program focus on maturing laboratory demonstrated technologies for potential adoption by specific mission applications. A key requirement for these programs success is a suitable queue of innovative technologies and advanced concepts to mature, including mission concepts enabled by innovative, cross cutting technology advancements. When considering space access, propulsion often dominates the capability requirements, as well as the attention and resources. From the perspective of access from space some new cross cutting technology drivers come into view, along with some new capability opportunities. These include new miniature vehicles (micro, nano, and picosats), advanced automated systems (providing autonomous on-orbit inspection or landing site selection), and transformable aeroshells (to maximize capabilities and minimize weight). This paper provides an assessment of the technology drivers needed to meet future access from space mission requirements, along with the mission capabilities that can be envisioned from innovative, cross cutting access from space technology developments.

  18. Advanced Water Recovery Technologies for Long Duration Space Exploration Missions (United States)

    Liu, Scan X.


    Extended-duration space travel and habitation require recovering water from wastewater generated in spacecrafts and extraterrestrial outposts since the largest consumable for human life support is water. Many wastewater treatment technologies used for terrestrial applications are adoptable to extraterrestrial situations but challenges remain as constraints of space flights and habitation impose severe limitations of these technologies. Membrane-based technologies, particularly membrane filtration, have been widely studied by NASA and NASA-funded research groups for possible applications in space wastewater treatment. The advantages of membrane filtration are apparent: it is energy-efficient and compact, needs little consumable other than replacement membranes and cleaning agents, and doesn't involve multiphase flow, which is big plus for operations under microgravity environment. However, membrane lifespan and performance are affected by the phenomena of concentration polarization and membrane fouling. This article attempts to survey current status of membrane technologies related to wastewater treatment and desalination in the context of space exploration and quantify them in terms of readiness level for space exploration. This paper also makes specific recommendations and predictions on how scientist and engineers involving designing, testing, and developing space-certified membrane-based advanced water recovery technologies can improve the likelihood of successful development of an effective regenerative human life support system for long-duration space missions.

  4. Critical Technologies for the Development of Future Space Elevator Systems (United States)

    Smitherman, David V., Jr.


    A space elevator is a tether structure extending through geosynchronous earth orbit (GEO) to the surface of the earth. Its center of mass is in GEO such that it orbits the earth in sync with the earth s rotation. In 2004 and 2005, the NASA Marshall Space Flight Center and the Institute for Scientific Research, Inc. worked under a cooperative agreement to research the feasibility of space elevator systems, and to advance the critical technologies required for the future development of space elevators for earth to orbit transportation. The discovery of carbon nanotubes in the early 1990's was the first indication that it might be possible to develop materials strong enough to make space elevator construction feasible. This report presents an overview of some of the latest NASA sponsored research on space elevator design, and the systems and materials that will be required to make space elevator construction possible. In conclusion, the most critical technology for earth-based space elevators is the successful development of ultra high strength carbon nanotube reinforced composites for ribbon construction in the 1OOGPa range. In addition, many intermediate technology goals and demonstration missions for the space elevator can provide significant advancements to other spaceflight and terrestrial applications.

  6. Technology Investment Agendas to Expand Human Space Futures (United States)

    Sherwood, Brent


    The paper develops four alternative core-technology advancement specifications, one for each of the four strategic goal options for government investment in human space flight. Already discussed in the literature, these are: Explore Mars; Settle the Moon; accelerate commercial development of Space Passenger Travel; and enable industrial scale-up of Space Solar Power for Earth. In the case of the Explore Mars goal, the paper starts with the contemporary NASA accounting of ?55 Mars-enabling technologies. The analysis decomposes that technology agenda into technologies applicable only to the Explore Mars goal, versus those applicable more broadly to the other three options. Salient technology needs of all four options are then elaborated to a comparable level of detail. The comparison differentiates how technologies or major developments that may seem the same at the level of budget lines or headlines (e.g., heavy-lift Earth launch) would in fact diverge widely if developed in the service of one or another of the HSF goals. The paper concludes that the explicit choice of human space flight goal matters greatly; an expensive portfolio of challenging technologies would not only enable a particular option, it would foreclose the others. Technologies essential to enable human exploration of Mars cannot prepare interchangeably for alternative futures; they would not allow us to choose later to Settle the Moon, unleash robust growth of Space Passenger Travel industries, or help the transition to a post-petroleum future with Space Solar Power for Earth. The paper concludes that a decades-long decision in the U.S.--whether made consciously or by default--to focus technology investment toward achieving human exploration of Mars someday would effectively preclude the alternative goals in our lifetime.

Critical technologies are those that enable a certain class of mission, such as technologies necessary for safe landing on the Martian surface, advanced propulsion, and closed loop life support. Others enhance the mission by leading to a greater satisfaction of mission objectives or increased probability of mission success. Advanced technologies are needed to reduce mass and cost. Many space agencies have studied exploration mission architectures and scenarios with the resulting lists of critical and enhancing technologies being very similar. With this in mind, and with the recognition that human space exploration will only be enabled by agencies working together to address these challenges, interested agencies participating in the International Space Exploration Coordination Group (ISECG) have agreed to perform a technology assessment as an important step in exploring cooperation opportunities for future exploration mission scenarios. "The Global Exploration Strategy: The Framework for Coordination" was developed by fourteen space agencies and released in May 2007. Since the fall of 2008, several International Space Exploration Coordination Group (ISECG) participating space agencies have been studying concepts for human exploration of the moon. They have identified technologies considered critical and enhancing of sustainable space exploration. Technologies such as in-situ resource utilization, advanced power generation/energy storage systems, reliable dust resistant mobility systems, and closed loop life support systems are important examples. Similarly, agencies such as NASA, ESA, and Russia have studied Mars exploration missions and identified critical technologies. They recognize that human and robotic precursor missions to destinations such as LEO, moon, and near earth objects provide opportunities to demonstrate the

  14. Introducing School Children in Nigeria to SPACE Technology As a Tool for Mitigation of National Catastrophes (United States)

    Alabi, O.


    The zonal workshops organized by the space education outreach unit of the African Regional Centre for Space Science and Technology Education utilized recent catastrophic events in Nigeria to attract pre-collegiate youths to space science and technology (SST). About 200 school children, aged between 10 and 18 years participated in the program which was coordinated at 2 different geopolitical zones in Nigeria in 2014. The 2-day event was packed with a lot of fun-filled, hands-on educational activities demonstrating the use of outer space to address prevailing socio-economic problems in the nation. The students were introduced to the Nigerian Earth Observation Satellites, and learned why these satellites cannot be used to track the school girls kidnapped by the terrorist group in the northern part of the country. They were also introduced to other types of satellites and participated in activities on the applications of TRMM satellite data to monitor flood events in Nigeria. The Global Positioning System (GPS) technology was introduced as a navigational tool to curb criminal activities in the country and participants used the hand-held GPS unit for geocaching. The program culminated in the launching of space clubs in all the participating schools and a teacher from each school received resource materials on DVD to nurture the space club. To assess the impact of the workshop on the knowledge level of the participants in space science, quiz competitions were administered and the average score of the students was above 70%. The enthusiasm displayed by the students, coupled with the brilliant performance in the evaluation tests, indicated that this method of informal education, that linked science to the alleviation of national disasters is viable, not only for stimulating the interest of Nigerian pre-collegiate youths in SST, but also to inspire the young learners and develop their interest in the Sciences, Technology, Engineering and Mathematics (STEM).

  15. Second Generation Reusable Launch Vehicle Development and Global Competitiveness of US Space Transportation Industry: Critical Success Factors Assessment (United States)

    Enyinda, Chris I.


    In response to the unrelenting call in both public and private sectors fora to reduce the high cost associated with space transportation, many innovative partially or fully RLV (Reusable Launch Vehicles) designs (X-34-37) were initiated. This call is directed at all levels of space missions including scientific, military, and commercial and all aspects of the missions such as nonrecurring development, manufacture, launch, and operations. According to Wertz, tbr over thirty years, the cost of space access has remained exceedingly high. The consensus in the popular press is that to decrease the current astronomical cost of access to space, more safer, reliable, and economically viable second generation RLVs (SGRLV) must be developed. Countries such as Brazil, India, Japan, and Israel are now gearing up to enter the global launch market with their own commercial space launch vehicles. NASA and the US space launch industry cannot afford to lag behind. Developing SGRLVs will immeasurably improve the US's space transportation capabilities by helping the US to regain the global commercial space markets while supporting the transportation capabilities of NASA's space missions, Developing the SGRLVs will provide affordable commercial space transportation that will assure the competitiveness of the US commercial space transportation industry in the 21st century. Commercial space launch systems are having difficulty obtaining financing because of the high cost and risk involved. Access to key financial markets is necessary for commercial space ventures. However, public sector programs in the form of tax incentives and credits, as well as loan guarantees are not yet available. The purpose of this paper is to stimulate discussion and assess the critical success factors germane for RLVs development and US global competitiveness.

    CERN Document Server

    Anelli, G; Faccio, F; Heijne, Erik H M; Jarron, Pierre; Kloukinas, Kostas C; Marchioro, A; Moreira, P; Snoeys, W


    The radiation environment present in some of today's High-Energy Physics (HEP) experiments and in space has a detrimental influence on the integrated circuits working in these environments. Special technologies, called radiation hardened, have been used in the past to prevent the radiation-induced degradation. In the last decades, the market of these special technologies has undergone a considerable shrinkage, rendering them less reliably available and far more expensive than today's mainstream technologies. An alternative approach is to use a deep submicron CMOS technology. The most sensitive part to radiation effects in a MOS transistor is the gate oxide. One way to reduce the effects of ionizing radiation in the gate oxide is to reduce its thickness, which is a natural trend in modern technologies. Submicron CMOS technologies seem therefore a good candidate for implementing radiation-hardened integrated circuits using a commercial, inexpensive technology. Nevertheless, a certain number of radiation-induced...

  17. Innovative Technologies for Efficient Pharmacotherapeutic Management in Space (United States)

    Putcha, Lakshmi; Daniels, Vernie


    Current and future Space exploration missions and extended human presence in space aboard the ISS will expose crew to risks that differ both quantitatively and qualitatively from those encountered before by space travelers and will impose an unknown risk of safety and crew health. The technology development challenges for optimizing therapeutics in space must include the development of pharmaceuticals with extended stability, optimal efficacy and bioavailability with minimal toxicity and side effects. Innovative technology development goals may include sustained/chronic delivery preventive health care products and vaccines, low-cost high-efficiency noninvasive, non-oral dosage forms with radio-protective formulation matrices and dispensing technologies coupled with self-reliant tracking technologies for quality assurance and quality control assessment. These revolutionary advances in pharmaceutical technology will assure human presence in space and healthy living on Earth. Additionally, the Joint Commission on Accreditation of Healthcare Organizations advocates the use of health information technologies to effectively execute all aspects of medication management (prescribing, dispensing, and administration). The advent of personalized medicine and highly streamlined treatment regimens stimulated interest in new technologies for medication management. Intelligent monitoring devices enhance medication accountability compliance, enable effective drug use, and offer appropriate storage and security conditions for dangerous drug and controlled substance medications in remote sites where traditional pharmacies are unavailable. These features are ideal for Exploration Medical Capabilities. This presentation will highlight current novel commercial off-the-shelf (COTS) intelligent medication management devices for the unique dispensing, therapeutic drug monitoring, medication tracking, and drug delivery demands of exploration space medical operations.

  18. Space matters: the relational power of mobile technologies

    Directory of Open Access Journals (Sweden)

    Nancy Odendaal


    Full Text Available The ubiquitous presence of mobile telephony and proliferation of digital networks imply a critical role for these technologies in overcoming the constraints of space in fragmented cities. Academic literature draws from a range of disciplines but fails to address the significance of new technologies for African and South African cities. Debates on technologies and urban spaces reflect a Northern bias and case literature that dwells on the developmental aspects of ICT do not engage with the broader significance with regards to urban change in African cities. This research addresses these gaps by examining the local transformative qualities of mobile telephony in a South African city, Durban. It focuses on the ways in which informal traders active in the city use technology. Actor-network theory was used in the analysis of the field work, uncovering material and human actors, network stabilization processes and agency in determining the transformative potential of this form of digital networking at city and local scales. Findings indicate that appropriation of technology is informed by livelihood strategies. Innovation is enabled when translation extends to appropriation. More in-depth research is needed on how technology is molded and appropriated to suit livelihoods. Throughout the research the spatial dimensions of the relationship between mobile telephony and networks were considered. The network spaces that emerge from actor relations do not correspond with the physical spaces usually considered in policy.

    T du Plessis


    Full Text Available Advances in the information and communication technologies have led to the availability of a range of primary and secondary legal research publications online via the Internet, rather than on other storing devices such as compact discs or publications in the print media. Not only has information and communication technology (ICT impacted on the availability of legal information resources, but its effects are also noticed in various law-related areas such as legal practice management, legal education, corporate governance and the law per se. The question addressed by this article is whether the application of ICTs has an effect on the practice of law, and specifically whether information and knowledge management affects the processes of legal research in modern legal practice. Various issues are considered in this regard, including what the concept of knowledge management (KM entails in a law firm and what the current KM trends in South African law firms are. The article investigates global trends in the application of ICTs for legal research purposes, what the specific applications of KM in support of legal research may be, how information technology applications and KM systems and strategies can support the legal research process, and what the benefits of KM are to legal research. It finally discusses the impact technology has had on the skills required of competitive legal professionals.

  1. Process analysis of technological competition and logistical substitution in world electronuclear system to the year 1986

    Energy Technology Data Exchange (ETDEWEB)

    Caira, M.; Spezia, U. (Rome Univ. La Sapienza (Italy))

    On the basis of the definitions established within the framework of Marchetti's logistic substitution model, an analysis of the process of technological competition at the international level among the different types of reactors was performed, through a quantitative and qualitative examination of the evolution of the role and the penetration of each of the industrially mature design configurations. The analysis covers the period between 1956 - the year the first reactors for civilian use began service - and 1985, and thus excludes the period of the 'Chernobyl emergency' and the following years, with the aim of obtaining an overall picture of the penetration of nuclear technologies in a market not influenced by obvious factors that condition the demand. The results of the analysis show a clear process of decline in the Western and Soviet graphite reactor types of the first generation (GCR and LGR), as well as, the role of predominant technology that is still undergoing an intense phase of expansion being assumed by the pressurized light water reactors (PWR). After the great successes of the years around 1970, the boiling water reactor (BWR) type seems to be undergoing a phase of reconsideration, while for the entire range of reactor types of the more recent generation (LMFBR, AGR, HTGR), no significant competitor capable of posing a serious threat to the PWR type has yet emerged, even after a phase of technological development that has lasted since 1972.

    Erikson, Jon D.


    This paper presents an overview of the proposed Lyndon B. Johnson Space Center (JSC) precompetitive, dual-use technology investment project in robotics. New robotic technology in advanced robots, which can recognize and respond to their environments and to spoken human supervision so as to perform a variety of combined mobility and manipulation tasks in various sectors, is an obejective of this work. In the U.S. economy, such robots offer the benefits of improved global competitiveness in a critical industrial sector; improved productivity by the end users of these robots; a growing robotics industry that produces jobs and profits; lower cost health care delivery with quality improvements; and, as these 'intelligent' robots become acceptable throughout society, an increase in the standard of living for everyone. In space, such robots will provide improved safety, reliability, and productivity as Space Station evolves, and will enable human space exploration (by human/robot teams). The proposed effort consists of partnerships between manufacturers, universities, and JSC to develop working production prototypes of these robots by leveraging current development by both sides. Currently targeted applications are in the manufacturing, health care, services, and construction sectors of the U.S. economy and in the inspection, servicing, maintenance, and repair aspects of space exploration. But the focus is on the generic software architecture and standardized interfaces for custom modules tailored for the various applications allowing end users to customize a robot as PC users customize PC's. Production prototypes would be completed in 5 years under this proposal.

    Rather, John D. G.


    Throughout history the emergence of new technologies has enabled unforeseen breakthrough capabilities that rapidly transformed the world. Some global examples from the twentieth century include AC electric power, nuclear energy, and turbojet engines. At the systems level, success of both Apollo and the Space Shuttle programs depended upon taming hydrogen propulsion and developing high-temperature atmospheric reentry materials. Human space development now is stymied because of a great need for breakthrough technologies and strategies. It is believed that new capabilities exist within the present states-of-the-art of superconducting technology that can be implemented to transform the future of human space development. This paper is an overview of three other papers presented within this forum, which summarizes the principles and consequences of StarTram, showing how the resulting breakthrough advantages can lead directly to safe space tourism and massive development of the moon, Mars and the outer solar system. StarTram can implement cost-effective solar power from space, simple utilization of asteroid material to protect humans from ionizing radiation, and effective defense of the Earth from devastating cosmic impacts. Synergistically, StarTram technologies will revolutionize ground transportation on the Earth, leading to enormous reduction in energy consumption and creation of millions of jobs. High energy lasers will also be discussed because of their importance to power beaming applications.

  10. Overview of Energy Storage Technologies for Space Applications (United States)

    Surampudi, Subbarao


    This presentations gives an overview of the energy storage technologies that are being used in space applications. Energy storage systems have been used in 99% of the robotic and human space missions launched since 1960. Energy storage is used in space missions to provide primary electrical power to launch vehicles, crew exploration vehicles, planetary probes, and astronaut equipment; store electrical energy in solar powered orbital and surface missions and provide electrical energy during eclipse periods; and, to meet peak power demands in nuclear powered rovers, landers, and planetary orbiters. The power source service life (discharge hours) dictates the choice of energy storage technology (capacitors, primary batteries, rechargeable batteries, fuel cells, regenerative fuel cells, flywheels). NASA is planning a number of robotic and human space exploration missions for the exploration of space. These missions will require energy storage devices with mass and volume efficiency, long life capability, an the ability to operate safely in extreme environments. Advanced energy storage technologies continue to be developed to meet future space mission needs.

  11. Free-piston Stirling technology for space power

    International Nuclear Information System (INIS)

    Slaby, J.G.


    An overview is presented of the NASA Lewis Research Center free-piston Stirling engine activities directed toward space power. This work is being carried out under NASA's new Civil Space Technology Initiative (CSTI). The overall goal of CSTI's High Capacity Power element is to develop the technology base needed to meet the long duration, high capacity power requirements for future NASA space missions. The Stirling cycle offers an attractive power conversion concept for space power needs. Discussed in this paper is the completion of the Space Power Demonstrator Engine (SPDE) testing - culminating in the generation of 25 kW of engine power from a dynamically-balanced opposed-piston Stirling engine at a temperature ratio of 2.0. Engine efficiency was approximately 22 percent. The SPDE recently has been divided into two separate single-cylinder engines, called Space Power Research Engines (SPRE), that now serve as test beds for the evaluation of key technology disciplines. These disciplines include hydrodynamic gas bearings, high-efficiency linear alternators, space qualified heat pipe heat exchangers, oscillating flow code validation, and engine loss understanding. The success of the SPDE at 650 K has resulted in a more ambitious Stirling endeavor - the design, fabrication, test and evaluation of a designed-for-space 25 kW per cylinder Stirling Space Engine (SSE). The SSE will operate at a hot metal temperature of 1050 K using superalloy materials. This design is a low temperature confirmation of the 1300 K design. It is the 1300 K free-piston Stirling power conversion system that is the ultimate goal; to be used in conjunction with the SP-100 reactor. The approach to this goal is in three temperature steps. However, this paper concentrates on the first two phases of this program - the 650 K SPDE and the 1050 K SSE

  12. Digital Social Media: An Interactive Technology Incorporated as a Competitive Advantage for Business

    Directory of Open Access Journals (Sweden)

    Pedro Pereira Correia


    Full Text Available In a more transparent and dynamic world, in which consumers trust other consumers more for advice and recommendations on products and services, the continuity of organizations appears to be associated with socialization, the sharing of interests and the interaction with the audience. This is associated with the incorporation of digital technologies to business, specifically the use of social media. Consequently, it is timely and interesting to explore the phenomenon of virtual socialization, although it is a little-studied field and what is needed is an innovative and theoretical approach based upon theories of marketing and communication. Expertise in these areas is present in all organizations and their performance is important for appropriate development of them. This work is a qualitative analysis about the behavior, reactions and attitudes of individuals to organizations, in order to understand the social factors that contribute to sustainable competitive advantages of organizations which can support strategic and future actions. We conclude that relevant factors associated with the tacit knowledge of the organization, specifically to learning and social interaction of the organization and their knowledge of virtual communities. The higher the coexistence of factors, the more difficult is the replication and greater will be the hypothesis of sustainable competitive advantage.

  13. Target validation for FCV technology development in Japan from energy competition point of view

    International Nuclear Information System (INIS)

    ENDO Eiichi


    The objective of this work is to validate the technical targets in the governmental hydrogen energy road-map of Japan by analyzing market penetration of fuel cell vehicle(FCV)s and effects of fuel price and carbon tax on it from technology competition point of view. In this analysis, an energy system model of Japan based on MARKAL is used. The results of the analysis show that hydrogen FCVs could not have cost-competitiveness until 2030 without carbon tax, including the governmental actual plan of carbon tax. However, as the carbon tax rate increases, instead of conventional vehicles including gasoline hybrid electric vehicle, hydrogen FCVs penetrate to the market earlier and more. By assuming higher fuel price and severer carbon tax rate, market share of hydrogen FCVs approaches to the governmental goal. This suggests that cheaper vehicle cost and/or hydrogen price than those targeted in the road-map is required. At the same time, achievement of the technical targets in the road-map also allows to attain the market penetration target of hydrogen FCVs in some possible conditions. (authors)

    International Nuclear Information System (INIS)

    Huh, Sung-Yoon; Lee, Chul-Yong


    Renewable energy technologies (RETs) have attracted significant public attention for several reasons, the most important being that they are clean alternative energy sources that help reduce greenhouse gas emissions. To increase the probability that RETs will be successful, it is essential to reduce the uncertainty about its adoption with accurate long-term demand forecasting. This study develops a diffusion model that incorporates the effect of competitive interrelationships among renewable sources to forecast the growth pattern of five RETs: solar photovoltaic, wind power, and fuel cell in the electric power sector, and solar thermal and geothermal energy in the heating sector. The 2-step forecasting procedure is based on the Bayus, (1993. Manage. Sci. 39, 11, 1319–1333) price function and a diffusion model suggested by Hahn et al. (1994. Marketing Sci. 13, 3, 224–247). In an empirical analysis, the model is applied to the South Korean renewable energy market. - Highlights: • We develop a diffusion model incorporating the competition among renewables. • A price function and a diffusion model are used in 2-step forecasting procedure. • The annual demand through 2035 for five renewables in South Korea is forecasted. • Wind power will maintain the largest market share in the electric power sector. • The supply of geothermal energy will be larger than that of solar thermal energy

  17. Technology issues associated with using densified hydrogen for space vehicles (United States)

    Hardy, Terry L.; Whalen, Margaret V.


    Slush hydrogen and triple-point hydrogen offer the potential for reducing the size and weight of future space vehicles because these fluids have greater densities than normal-boiling-point liquid hydrogen. In addition, these fluids have greater heat capacities, which make them attractive fuels for such applications as the National Aerospace Plane and cryogenic depots. Some of the benefits of using slush hydrogen and triple-point hydrogen for space missions are quantified. Some of the major issues associated with using these densified cryogenic fuels for space applications are examined, and the technology efforts that have been made to address many of these issues are summarized.

  19. Medical and surgical applications of space biosensor technology (United States)

    Hines, John W.


    Researchers in space life sciences are rapidly approaching a technology impasse. Many of the critical questions on the impact of spaceflight on living systems simply cannot be answered with the limited available technologies. Research subjects, particularly small animal models like the rat, must be allowed to function relatively untended and unrestrained for long periods to fully reflect the impact of microgravity and spaceflight on their behavior and physiology. These requirements preclude the use of present hard-wired instrumentation techniques and limited data acquisition systems. Implantable sensors and miniaturized biotelemetry are the only means of capturing the fundamental and critical data. This same biosensor and biotelemetry technology has direct application to Earth-based medicine and surgery. Continuous, on-line data acquisition and improved measurement capabilities combined with the ease and flexibility offered by automated, wireless, and portable instruments and data systems, should provide a boon to the health care industry. Playing a key role in this technology revolution is the Sensors 2000! (S2K!) Program at NASA Ames Research Center. S2K!, in collaboration with space life sciences researchers and managers, provides an integrated capability for sensor technology development and applications, including advanced biosensor technology development, spaceflight hardware development, and technology transfer and commercialization. S2K! is presently collaborating on several spaceflight projects with dual-use medical applications. One prime example is a collaboration with the Fetal Treatment Center (FTC) at the University of California at San Francisco. The goal is to develop and apply implantable chemical sensor and biotelemetry technology to continuously monitor fetal patients during extra-uterine surgery, replacement into the womb, through birth and beyond. Once validated for ground use, the method will be transitioned to spaceflight applications to

  20. Transformational System Concepts and Technologies for Our Future in Space (United States)

    Howell, Joe T.; Mankins, John C.


    Continued constrained budgets and growing national and international interests in the commercialization and development of space requires NASA to be constantly vigilant, to be creative, and to seize every opportunity for assuring the maximum return on space infrastructure investments. Accordingly, efforts are underway to forge new and innovative approaches to transform our space systems in the future to ultimately achieve two or three or five times as much with the same resources. This bold undertaking can be achieved only through extensive cooperative efforts throughout the aerospace community and truly effective planning to pursue advanced space system design concepts and high-risk/high-leverage research and technology. Definitive implementation strategies and roadmaps containing new methodologies and revolutionary approaches must be developed to economically accommodate the continued exploration and development of space. Transformation can be realized through modular design and stepping stone development. This approach involves sustainable budget levels and multi-purpose systems development of supporting capabilities that lead to a diverse amy of sustainable future space activities. Transformational design and development requires revolutionary advances by using modular designs and a planned, stepping stone development process. A modular approach to space systems potentially offers many improvements over traditional one-of-a-kind space systems comprised of different subsystem element with little standardization in interfaces or functionality. Modular systems must be more flexible, scaleable, reconfigurable, and evolvable. Costs can be reduced through learning curve effects and economies of scale, and by enabling servicing and repair that would not otherwise be feasible. This paper briefly discusses achieving a promising approach to transforming space systems planning and evolution into a meaningful stepping stone design, development, and implementation process

  5. 2004 Space Report: Environment and Strategy for Space Research at NATO's Research and Technology Organisation (RTO) (United States)

    Woods-Vedeler, Jessica A.


    This report describes the motivation for and a strategy to enhance the NATO Research and Technology Organisation's (RTO) current space research effort to reflect NATO's growing military dependence on space systems. Such systems and services provided by these systems are critical elements of military operations. NATO uses space systems for operational planning and support, communication, radio navigation, multi-sensor and multi-domain demonstrations. Such systems are also used to promote regional stability. A quantitative analysis of work related to space in the NATO RTO showed that during the period of 1998 - 2004, 5% of the research pursued in the NATO RTO has been clearly focused on space applications. Challenging environmental and organizational barriers for increasing RTO space research were identified. In part, these include lack of sufficient space expertise representation on panels, the military sensitivity of space, current panel work loads and the need for specific technical recommendations from peers. A strategy for enhancing space research in the RTO is to create a limited-life Space Advisory Group (SAG) composed of Space Expert Consultants who are panel members with appropriate expertise and additional expertise from the nations. The SAG will recommend and find support in the nations for specific technical activities related to space in the areas of Space Science, Remote Sensing Data Analysis, Spacecraft Systems, Surveillance and Early Warning, Training and Simulation and Policy. An RTO Space Advisory Group will provide an organizational mechanism to gain recognition of RTO as a forum for trans-Atlantic defence space research and to enhance space research activities.

  10. Space Resource Utilization: Technologies and Potential Synergism with Terrestrial Mining (United States)

    Sanders, Gerald B.


    Space Resources and Their Uses: The idea of using resources in space to support human exploration and settlement or for economic development and profit beyond the surface of Earth has been proposed and discussed for decades. Work on developing a method to extract oxygen from lunar regolith started even before humans set foot on the Moon for the first time. The use of space resources, commonly referred to as In Situ Resource Utilization (ISRU), involves the processes and operations to harness and utilize resources in space (both natural and discarded) to create products for subsequent use. Potential space resources include water, solar wind implanted volatiles (hydrogen, helium, carbon, nitrogen, etc.), vast quantities of metals and minerals in extraterrestrial soils, atmospheric constituents, unlimited solar energy, regions of permanent light and darkness, the vacuum and zero-gravity of space itself, trash and waste from human crew activities, and discarded hardware that has completed its primary purpose. ISRU covers a wide variety of concepts, technical disciplines, technologies, and processes. When considering all aspects of ISRU, there are 5 main areas that are relevant to human space exploration and the commercialization of space: 1. Resource Characterization and Mapping, 2. In Situ Consumables Production, 3. Civil Engineering and Construction, 4. In Situ Energy Production and Storage, and 5. In Situ Manufacturing.

  11. Composites Materials and Manufacturing Technologies for Space Applications (United States)

    Vickers, J. H.; Tate, L. C.; Gaddis, S. W.; Neal, R. E.


    Composite materials offer significant advantages in space applications. Weight reduction is imperative for deep space systems. However, the pathway to deployment of composites alternatives is problematic. Improvements in the materials and processes are needed, and extensive testing is required to validate the performance, qualify the materials and processes, and certify components. Addressing these challenges could lead to the confident adoption of composites in space applications and provide spin-off technical capabilities for the aerospace and other industries. To address the issues associated with composites applications in space systems, NASA sponsored a Technical Interchange Meeting (TIM) entitled, "Composites Materials and Manufacturing Technologies for Space Applications," the proceedings of which are summarized in this Conference Publication. The NASA Space Technology Mission Directorate and the Game Changing Program chartered the meeting. The meeting was hosted by the National Center for Advanced Manufacturing (NCAM)-a public/private partnership between NASA, the State of Louisiana, Louisiana State University, industry, and academia, in association with the American Composites Manufacturers Association. The Louisiana Center for Manufacturing Sciences served as the coordinator for the TIM.

    Mercer, Carolyn R.; Vangen, Scott D.; Williams-Byrd, Julie A.; Stecklein, Jonette M.; Rahman, Shamim A.; Rosenthal, Matthew E.; Hornyak, David M.; Alexander, Leslie; Korsmeyer, David J.; Tu, Eugene L.; hide


    As the National Aeronautics and Space Administration (NASA) prepares to extend human presence throughout the solar system, technical capabilities must be developed to enable long duration flights to destinations such as near Earth asteroids, Mars, and extended stays on the Moon. As part of the NASA Human Spaceflight Architecture Team, a Technology Development Assessment Team has identified a suite of critical technologies needed to support this broad range of missions. Dialog between mission planners, vehicle developers, and technologists was used to identify a minimum but sufficient set of technologies, noting that needs are created by specific mission architecture requirements, yet specific designs are enabled by technologies. Further consideration was given to the re-use of underlying technologies to cover multiple missions to effectively use scarce resources. This suite of critical technologies is expected to provide the needed base capability to enable a variety of possible destinations and missions. This paper describes the methodology used to provide an architecture-driven technology development assessment ("technology pull"), including technology advancement needs identified by trade studies encompassing a spectrum of flight elements and destination design reference missions.

    Full Text Available The article shows that the international network of electronic communication helps the various economic agents to find new partners, to respond more quickly to the changing conditions, facilitate greater interaction of economic partners and establishment of the trusting and long-term relationships, reduce the transaction costs and the distance between the partners, while simultaneously increasing the economic benefits of their relationship. It justifies the fact that the widespread implementation of information and communication technologies in Ukraine might contribute to increasing the number of small businesses and private business organizations, as well as strengthening their competitive positions in the domestic and foreign markets. This article proves that the use of ICTs can enhance the effectiveness of the production and companies’ management system by increasing their access to the information, knowledge, financial services and other resources. As explained in this work, thanks to the use of ICTs, new opportunities are created for the small private enterprises to develop the existing and discover new types and directions of activity, which will contribute to the improvement of the well-being of the population. It also rationalizes that the expansion of the ICTs’ usage by the government and other public bodies may support the increase of the business environment transparency and simplification of the procedures for starting and running a business. It determines why the spread of information technology, especially in our country, requires governmental support, primarily on the development of information infrastructure and adaptation of the legislation to the conditions of the information economy.

  14. Healthy competition: A qualitative study investigating persuasive technologies and the gamification of cycling. (United States)

    Barratt, Paul


    Changing socio-technical practices occurring within cycling are leading the pursuit, and its participants, to become ever more embedded into the networked digital world. GPS enabled mobile-technologies have introduced a new element of competition into recreational riding, whether on the road, competing over timed virtual segments, or online dissecting and comparing the data that has been logged and shared via dedicated ride-logging applications. In order to understand these technologies qualitative study using reflective diaries and semi-structured interviews has been conducted with experienced club cyclists who had fully experienced the effects of their arrival. These riders claim that the applications influence their route choice and motivate them to cycle more frequently, and at a greater intensity although the engagement changes over time. This paper explores how this increased motivation to exercise and compete is instigated, manifested and maintained in the everyday practices of cyclists, as well as the negative consequences of gamification.

  15. Product Variety, Consumer Preferences, and Web Technology: Can the Web of Data Reduce Price Competition and Increase Customer Satisfaction? (United States)

    Hepp, Martin

    E-Commerce on the basis of current Web technology has created fierce competition with a strong focus on price. Despite a huge variety of offerings and diversity in the individual preferences of consumers, current Web search fosters a very early reduction of the search space to just a few commodity makes and models. As soon as this reduction has taken place, search is reduced to flat price comparison. This is unfortunate for the manufacturers and vendors, because their individual value proposition for a particular customer may get lost in the course of communication over the Web, and it is unfortunate for the customer, because he/she may not get the most utility for the money based on her/his preference function. A key limitation is that consumers cannot search using a consolidated view on all alternative offers across the Web. In this talk, I will (1) analyze the technical effects of products and services search on the Web that cause this mismatch between supply and demand, (2) evaluate how the GoodRelations vocabulary and the current Web of Data movement can improve the situation, (3) give a brief hands-on demonstration, and (4) sketch business models for the various market participants.

    Orjala, M.; Leino, T.; Kaerki, J.; Haemaelaeinen, J. (VTT Technical Research Centre of Finland, Jyvaeskylae (Finland)), Email:, Email:, Email:, Email:


    The global use of biomass fuels is increasing significantly which also means that the fuel assortment will be increased strongly in the future. These new fuels, however, are often more challenging from the point of both production and site handling methods, and their combustion properties than the more traditional fuels. The increment of the biomass assortment creates a need for further development of combustion technologies. VTT creates with its collaborators possibilities for new generation multi-fuel boiler research and product development environment that enables the development of efficient solutions for utilisation of new biomass fuels. The research environment will be constructed during 2009 by the side of the new heating plant located at Saarijaervi. 'The future multi-fuel boiler' - research environment offers a unique possibility to develop solutions for the total biomass chain, from production of the fuel to fuel handling, and the combustion process. The research environment offers abilities, e.g. the analysis of the total biomass supply chain and new concept demonstration, as well as training possibilities for both domestic and international customers of Finnish equipment suppliers. Through the research and development abilities VTT and its co-operators want to develop the branch in co-operation with all actors in bioenergy chain. Co-operators in the research are currently Saarijaerven Kaukolaempoe Oy, boiler supplier Putkimaa, University of Jyvaeskylae and JAMK University of Applied Sciences. In the future the objective is to increase both the national and European co-operation with universities, equipment suppliers and energy companies, and hence to improve the competitiveness of Finnish equipment suppliers and energy companies, and hence to improve the competitiveness of Finnish equipment suppliers on the international markets.

Feasibility studies are a central component of ensuring successful recruitment and retention. A feasibility study is an assessment of the practicality of a proposed study protocol, with the goal of understanding challenges and providing risk mitigation strategies leading to better subject enrolment and study start-up should the assessment be favorable. This paper presents findings from a retrospective case series of RA feasibilities, describing important parameters to consider in the highly competitive RA space in Asia. Key parameters identified and discussed are how decisions on clinical development strategy necessitate changes in the clinical operational delivery strategy, with focus on changes in inclusion and exclusion criteria and patient contribution load; how small the patient population becomes when the clinical trial needs to target the patient population that is refractory to standard therapy; regulatory timelines; and the competitive clinical trial landscape. Feasibility assessments are a snapshot in time exercise. Multiple parameters change over time, and, particularly in a space that has become competitive for subjects, one cannot rely on one static feasibility assessment to predict trial performance accurately. Continuous feasibility assessment will also provide insight into the resourcing needs on the part of the sponsor, contract research organization, and investigative site.Keywords: site selection, country selection, clinical operations, risk management, recruitment rates

  20. Status of Propulsion Technology Development Under the NASA In-Space Propulsion Technology Program (United States)

    Anderson, David; Kamhawi, Hani; Patterson, Mike; Pencil, Eric; Pinero, Luis; Falck, Robert; Dankanich, John


    Since 2001, the In-Space Propulsion Technology (ISPT) program has been developing and delivering in-space propulsion technologies for NASA's Science Mission Directorate (SMD). These in-space propulsion technologies are applicable, and potentially enabling for future NASA Discovery, New Frontiers, Flagship and sample return missions currently under consideration. The ISPT program is currently developing technology in three areas that include Propulsion System Technologies, Entry Vehicle Technologies, and Systems/Mission Analysis. ISPT's propulsion technologies include: 1) the 0.6-7 kW NASA's Evolutionary Xenon Thruster (NEXT) gridded ion propulsion system; 2) a 0.3-3.9kW Halleffect electric propulsion (HEP) system for low cost and sample return missions; 3) the Xenon Flow Control Module (XFCM); 4) ultra-lightweight propellant tank technologies (ULTT); and 5) propulsion technologies for a Mars Ascent Vehicle (MAV). The NEXT Long Duration Test (LDT) recently exceeded 50,000 hours of operation and 900 kg throughput, corresponding to 34.8 MN-s of total impulse delivered. The HEP system is composed of the High Voltage Hall Accelerator (HIVHAC) thruster, a power processing unit (PPU), and the XFCM. NEXT and the HIVHAC are throttle-able electric propulsion systems for planetary science missions. The XFCM and ULTT are two component technologies which being developed with nearer-term flight infusion in mind. Several of the ISPT technologies are related to sample return missions needs: MAV propulsion and electric propulsion. And finally, one focus of the Systems/Mission Analysis area is developing tools that aid the application or operation of these technologies on wide variety of mission concepts. This paper provides a brief overview of the ISPT program, describing the development status and technology infusion readiness.

  1. Applications of Space-Age Technology in Anthropology (United States)


    The papers in this volume were presented at a conference entitled, 'Applications of Space-Age Technology in Anthropology,' held November 28, 1990, at NASA's Science and Technology Laboratory. One reason for this conference was to facilitate information exchange among a diverse group of anthropologists. Much of the research in anthropology that has made use of satellite image processing, geographical information systems, and global positioning systems has been known to only a small group of practitioners. A second reason for this conference was to promote scientific dialogue between anthropologists and professionals outside of anthropology. It is certain that both the development and proper application of new technologies will only result from greater cooperation between technicians and 'end-users.' Anthropologists can provide many useful applications to justify the costs of new technological development.

  2. JSFR: Japan's challenge towards the competitive SFR design concept with innovative technologies

    International Nuclear Information System (INIS)

    Mihara, T.; Kotake, S.


    JSFR is a sodium-cooled, MOX(or metal) fuelled, advanced loop type fast reactor design concept conducting by Japan Atomic Energy Agency(JAEA) through the Feasibility Study on commercialized Fast Reactor(FR) Cycle Systems with participation of all parties concerned in Japan since 1999. The economic competitiveness is one of the crucial points and has been emphasized in the design study of JSFR. One of the ways for less construction cost is the compact NSSS design by introducing the following innovative technologies; Shortening the piping length, simplified configuration with the inverse L-shaped-pipes and a two-loop system even for a l,500MWe power plant, by adopting high chromium steel with lower thermal expansion and higher strength, Upgrading of the structural design standards at elevated temperature for sodium-cooled FR system, and Development of an integrated intermediate heat exchanger (IHX) with a mechanical pump. The other way is introducing passive decay heat removal system with natural circulation. The elimination of active components such as pony motors and blowers leads to reduction of the capacity of the BOP system such as electricity supply system, emergency DGs, HVAC system and component cooling water system. In order to attain lower power generation cost, not only less construction cost but also less operational cost including fuel cycle cost is crucial. Therefore higher burn-up of the averaged core, more than 150GWd/t, has been applied by introducing ODS steel cladding material. As a result, it is confirmed that the JSFR design concept is well suited to the development target equivalent to l,000USD/kWe (as NOAK, overnight cost), while ensuring safety. The most of the cost reduction comes from the innovative technologies. The R and D plan of these technologies was summarized as a roadmap and the R and D efforts are on going for establishing a technical scheme of FR cycle systems by around 2015

  4. Definition of technology development missions for early space stations: Large space structures (United States)

    Gates, R. M.; Reid, G.


    The objectives studied are the definition of the tested role of an early Space Station for the construction of large space structures. This is accomplished by defining the LSS technology development missions (TDMs) identified in phase 1. Design and operations trade studies are used to identify the best structural concepts and procedures for each TDMs. Details of the TDM designs are then developed along with their operational requirements. Space Station resources required for each mission, both human and physical, are identified. The costs and development schedules for the TDMs provide an indication of the programs needed to develop these missions.

  5. Theoretical analysis of the optimal configuration of co-generation systems and competitiveness of heating/cooling technologies

    This study aims at exploiting optimal configurations of technologies combined with co-generation theoretically based on a linear optimization model. With the objective function defining primary energy consumption to be minimized, optimal solutions are derived analytically. They describe the technological configurations as well as associated conditions depending on their final energy demand. An interesting finding is that the essential parameters to determine the configurations are heat, cooling and steam demands normalized by power demand. The optimal solutions are also applied to investigate the competitiveness of co-generation related technologies. The optimal solutions yield critical conditions theoretically, which is useful to understand the priority of the technologies. A sensitivity analysis numerically indicates that absorption chillers can be superior to compression chillers even though the former has lower COP than the latter. Actual data of various types of co-generation are also examined to show the practical competitiveness. (author)

    R and D and, more recently, technological innovation and its relationship with competitivity are more and more part of conferences, books, articles and political speeches and very often are the central part of them. Innovation has become fashionable and many initiatives have come out in connection with it. However, the relationship between technological innovation and competitivity are not always obvious. The current article intends to illustrate some mechanisms that link these two concepts through a specific case, DTN, that is already providing results for the Spanish nuclear industry and whose example can be extrapolated to other industrial sectors. The importance given by the nuclear to the innovation, the research and the technological development it is not new either exclusively belong to any specific organisation but makes evident the coherence between its traditional approach and the current idea of modernizing the country promoting the national technological capacity.

    Shayler, David J


    How could the newly authorized space shuttle help in the U.S. quest to build a large research station in Earth orbit? As a means of transporting goods, the shuttle could help supply the parts to the station. But how would the two entitles be physically linked? Docking technologies had to constantly evolve as the designs of the early space stations changed. It was hoped the shuttle would make missions to the Russian Salyut and American Skylab stations, but these were postponed until the Mir station became available, while plans for getting a new U. S. space station underway were stalled. In Linking the Space Shuttle and Space Stations, the author delves into the rich history of the Space Shuttle and its connection to these early space stations, culminating in the nine missions to dock the shuttle to Mir. By 1998, after nearly three decades of planning and operations, shuttle missions to Mir had resulted in: • A proven system to link up the space shuttle to a space station • Equipment and hands-on experienc...

  14. Space Life Support Technology Applications to Terrestrial Environmental Problems (United States)

    Schwartzkopf, Steven H.; Sleeper, Howard L.


    Many of the problems now facing the human race on Earth are, in fact, life support issues. Decline of air Quality as a result of industrial and automotive emissions, pollution of ground water by organic pesticides or solvents, and the disposal of solid wastes are all examples of environmental problems that we must solve to sustain human life. The technologies currently under development to solve the problems of supporting human life for advanced space missions are extraordinarily synergistic with these environmental problems. The development of these technologies (including both physicochemical and bioregenerative types) is increasingly focused on closing the life support loop by removing and recycling contaminants and wastes to produce the materials necessary to sustain human life. By so doing, this technology development effort also focuses automatically on reducing resupply logistics requirements and increasing crew safety through increased self-sufficiency. This paper describes several technologies that have been developed to support human life in space and illustrates the applicability of the technologies to environmental problems including environmental remediation and pollution prevention.

  15. Legal and Regulatroy Obstacles to Nuclear Fission Technology in Space (United States)

    Force, Melissa K.


    In forecasting the prospective use of small nuclear reactors for spacecraft and space-based power stations, the U.S. Air Force describes space as "the ultimate high ground," providing access to every part of the globe. But is it? A report titled "Energy Horizons: United States Air Force Energy Science &Technology Vision 2011-2026," focuses on core Air Force missions in space energy generation, operations and propulsion and recognizes that investments into small modular nuclear fission reactors can be leveraged for space-based systems. However, the report mentions, as an aside, that "potential catastrophic outcomes" are an element to be weighed and provides no insight into the monumental political and legal will required to overcome the mere stigma of nuclear energy, even when referring only to the most benign nuclear power generation systems - RTGs. On the heels of that report, a joint Department of Energy and NASA team published positive results from the demonstration of a uranium- powered fission reactor. The experiment was perhaps most notable for exemplifying just how effective the powerful anti-nuclear lobby has been in the United States: It was the first such demonstration of its kind in nearly fifty years. Space visionaries must anticipate a difficult war, consisting of multiple battles that must be waged in order to obtain a license to fly any but the feeblest of nuclear power sources in space. This paper aims to guide the reader through the obstacles to be overcome before nuclear fission technology can be put to use in space.

YSC educational activities are based on the concept of uninterrupted aerospace education, developed and implemented by the center. The concept includes working with young space interested people both in school and university and then assisting them in getting interesting job in Russian Space Industry. The school level educational activities of the center has got different forms, such as lecturing, summer scientific camps and even Classes from Space given by Mir space station flight crew in Mission Control Center - Moscow and done in cooperation with All- Russian Aerospace Society Soyuz (VAKO Soyuz). This helps to stimulate the young people interest to the fundamental sciences ( physics, mathematics, computer science, etc.) exploiting and developing their interest to space and thus increase the overall educational level in the country. YSC hosts annual Cosmonautics conference for high school students that provides the University with capability to select well-prepared and motivated students for its' rocket and space related departments. For the conference participants it's a good opportunity to be enrolled to the University without entrance examinations. BMSTU students can participate in such YSC activities as annual international workshop for space

  1. Thermionic integrated circuit technology for high power space applications

    International Nuclear Information System (INIS)

    Yadavalli, S.R.


    Thermionic triode and integrated circuit technology is in its infancy and it is emerging. The Thermionic triode can operate at relatively high voltages (up to 2000V) and at least tens of amperes. These devices, including their use in integrated circuitry, operate at high temperatures (800 0 C) and are very tolerant to nuclear and other radiations. These properties can be very useful in large space power applications such as that represented by the SP-100 system which uses a nuclear reactor. This paper presents an assessment of the application of thermionic integrated circuitry with space nuclear power system technology. A comparison is made with conventional semiconductor circuitry considering a dissipative shunt regulator for SP-100 type nuclear power system rated at 100 kW. The particular advantages of thermionic circuitry are significant reductions in size and mass of heat dissipation and radiation shield subsystems

    The problem of a comparative analysis of objects of rocket and space technology is formulated in terms of one of fundamental problems of the system analysis, namely, comparisons of objects on set of diverse criteria. A procedure for a comparative estimation based on the method of the analytic hierarchy process is offered as an algorithm. We give an example, namely, a comparison of launcher-carriers, derived with the use of our software.

  3. Advanced Mirror Technology Development for Very Large Space Telescopes (United States)

    Stahl, H. P.


    Advanced Mirror Technology Development (AMTD) is a NASA Strategic Astrophysics Technology project to mature to TRL-6 the critical technologies needed to produce 4-m or larger flight-qualified UVOIR mirrors by 2018 so that a viable mission can be considered by the 2020 Decadal Review. The developed mirror technology must enable missions capable of both general astrophysics & ultra-high contrast observations of exoplanets. Just as JWST’s architecture was driven by launch vehicle, a future UVOIR mission’s architectures (monolithic, segmented or interferometric) will depend on capacities of future launch vehicles (and budget). Since we cannot predict the future, we must prepare for all potential futures. Therefore, to provide the science community with options, we are pursuing multiple technology paths. AMTD uses a science-driven systems engineering approach. We derived engineering specifications for potential future monolithic or segmented space telescopes based on science needs and implement constraints. And we are maturing six inter-linked critical technologies to enable potential future large aperture UVOIR space telescope: 1) Large-Aperture, Low Areal Density, High Stiffness Mirrors, 2) Support Systems, 3) Mid/High Spatial Frequency Figure Error, 4) Segment Edges, 5) Segment-to-Segment Gap Phasing, and 6) Integrated Model Validation Science Advisory Team and a Systems Engineering Team. We are maturing all six technologies simultaneously because all are required to make a primary mirror assembly (PMA); and, it is the PMA’s on-orbit performance which determines science return. PMA stiffness depends on substrate and support stiffness. Ability to cost-effectively eliminate mid/high spatial figure errors and polishing edges depends on substrate stiffness. On-orbit thermal and mechanical performance depends on substrate stiffness, the coefficient of thermal expansion (CTE) and thermal mass. And, segment-to-segment phasing depends on substrate & structure stiffness

  4. Technology assessment for Spaceship Two, space tourism, and private spaceflight (United States)

    Hancock, Randy

    A seven-step technology assessment was conducted to address questions regarding the significance and likely consequences associated with the introduction of Spaceship Two, space tourism, and private spaceflight. Impacts were assessed across four categories: the Role and Functions of Government, Private Industry Factors, Cultural and Societal Impacts, and the Time Frame in which these impacts were anticipated to occur. The technology assessment findings were compared to the results of expert interviews that addressed the sane four categories. The researcher noted that, while there was overwhelming agreement between the technology assessment's primary impacts and the expert interview responses, there were several differences. The technology assessment and interviewees agreed that the federal government would likely be both a regulator and user of private spaceflight. Both agreed that business partnerships would be key in pursuing private spaceflight. There was also consensus that, as market forces come to bear, ticket prices would drop and a larger market and broader passenger demographic would emerge. The technology assessment and experts agreed that an accident, especially one early in the industry's evolution, could be disastrous. Both agreed that private spaceflight can serve as a inspiration to students and be a positive influence in society, and both agreed that the start of passenger flights should take place in the 2010 - 2012 timeframe. Due to the potentially disastrous consequences of an accident, there was agreement between the technology assessment and experts on the value of flight and ground crew training, driven by insurance carriers and federal mandate. Most differences between the technology assessment's findings and the expert interview responses were due to omission, rather than direct disagreement. However, this was not the case in every instance. The most significant difference between the technology assessment and the experts involved the

  5. Technical and Economical study of New Technologies and Reusable Space Vehicles promoting Space Tourism. (United States)

    Srivastav, Deepanshu; Malhotra, Sahil


    For many of us space tourism is an extremely fascinating and attractive idea. But in order for these to start we need vehicles that will take us to orbit and bring us back. Current space vehicles clearly cannot. Only the Space Shuttle survives past one use, and that's only if we ignore the various parts that fall off on the way up. So we need reusable launch vehicles. Launch of these vehicles to orbit requires accelerating to Mach 26, and therefore it uses a lot of propellant - about 10 tons per passenger. But there is no technical reason why reusable launch vehicles couldn't come to be operated routinely, just like aircraft. The main problem about space is how much it costs to get there, it's too expensive. And that's mainly because launch vehicles are expendable - either entirely, like satellite launchers, or partly, like the space shuttle. The trouble is that these will not only reduce the cost of launch - they'll also put the makers out of business, unless there's more to launch than just a few satellites a year, as there are today. Fortunately there's a market that will generate far more launch business than satellites ever well - passenger travel. This paper assesses this emerging market as well as technology that will make space tourism feasible. The main conclusion is that space vehicles can reduce the cost of human transport to orbit sufficiently for large new commercial markets to develop. Combining the reusability of space vehicles with the high traffic levels of space tourism offers the prospect of a thousandfold reduction in the cost per seat to orbit. The result will be airline operations to orbit involving dozens of space vehicles, each capable of more than one flight per day. These low costs will make possible a rapid expansion of space science and exploration. Luckily research aimed at developing low-cost reusable launch vehicles has increased recently. Already there are various projects like Spaceshipone, Spaceshiptwo, Spacebus, X-33 NASA etc. The

  6. Space Suit Environment Testing of the Orion Atmosphere Revitalization Technology (United States)

    Button, Amy B.; Sweterlitsch, Jeffrey J.; Cox, Marlon R.


    An amine-based carbon dioxide (CO2) and water vapor sorbent in pressure-swing regenerable beds has been developed by Hamilton Sundstrand and baselined for the Orion Atmosphere Revitalization System (ARS). In three previous years at this conference, reports were presented on extensive Johnson Space Center (JSC) testing of this technology. That testing was performed in a sea-level pressure environment with both simulated and real human metabolic loads, and in both open and closed-loop configurations. The Orion ARS is designed to also support space-suited operations in a depressurized cabin, so the next step in developmental testing at JSC was to test the ARS technology in a typical closed space suit-loop environment with low-pressure oxygen inside the process loop and vacuum outside the loop. This was the first instance of low-pressure, high-oxygen, closed-loop testing of the Orion ARS technology, and it was conducted with simulated human metabolic loads in March 2009. The test investigated pressure drops and flow balancing through two different styles of prototype suit umbilical connectors. General swing-bed performance was tested with both umbilical configurations, as well as with a short jumper line installed in place of the umbilicals. Other interesting results include observations on the thermal effects of swing-bed operation in a vacuum environment and a recommendation of cycle time to maintain acceptable suit atmospheric CO2 and moisture levels.

    Nieto, Jose; Yuste, Laura; Pipo, Alvaro; Santarsiero, Pablo; Bureo, Rafael


    Carbon Fiber Reinforced Plastic (CFRP) is commonly used in space applications to get structures with good mechanical performances and a reduced mass. Most of larger parts of spatial structures are already made of CFRP but the achieved weight saving may be jeopardized by the use of metallic brackets as joining elements. This paper describes the work carried out to study and evaluate ways of reducing weight and costs of the joints between structural elements commonly used in space applications.The main objective of this project is to adapt design solutions coming from the racing sailing boats technology to space applications: the use of out-of autoclave (OoA) cured CFRP joints. In addition to that other CFRP solution common in space business, 3D- RTM Bracket, has been evaluated.This development studies the manufacturing and assembly feasibility making use of these CFRP technologies.This study also compares traditional metallic solutions with innovative CFRP ones in terms of mechanical performances at elementary level. Weight and cost of presented solutions are also compared.

    Yamagiwa, Yoshiki; Nohmi, Masahiro; Aoki, Yoshio; Momonoi, Yu; Nanba, Hirotaka; Aiga, Masanori; Kumao, Takeru; Watahiki, Masahito


    We attempt to verify two basic technologies required for a space elevator using microsatellites; the tether (cable) deployment technology and the climber operation along the tether in space. Tether deployment is performed by a CubeSat called STARS-C (Space Tethered Autonomous Robotic Satellite - Cube) which will be released from the Japanese experimental module Kibo on ISS early in 2017. STARS-C consists of a mother satellite (MS) and daughter satellite (DS) connected by a 100-m tether. Its mission is focused on the tether deployment for studying the tether dynamics during the deployment with the goal of improving the smoothness of such deployment in future tether missions including space elevator. The MS and DS have common subsystems, including power, communication, and command and data handling systems. They also have a tether unit with spool and reel mechanisms as a mission system. In addition, we have been designing the next-step microsatellite called STARS-E (Space Tethered Autonomous Robotic Satellite - Elevator) under a Grant-in-Aid for Scientific Research. STARS-E is a 500-mm size satellite intended to verify the climber operation in space. It consists of a MS and DS jointed by a 2-km tether, and a climber that moves along the tether. STARS-C was launched on December 9 in 2016 and will be performed its mission early in 2017. STARS-E is in the BBM phase, and some designs are currently being fixed.

    The demand of fossil fuels, including oil, gas, and coal has been increasing with the rapid development of developing countries such as China and India. U.S., Japan, EU, and Korea have been making efforts to transfer to low carbon and green growth economics for sustainable development. And they also have been measuring to cope with climate change and the depletion of conventional fuels. Advanced nations implemented strategic energy technology development plans to lead the future energy market. Strategic energy technology development is crucial alternative to address the energy issues. This paper analyze the relative competitiveness of hydrogen energy technologies in case of hydrogen production and storage technologies from 2006 to 2010. Hydrogen energy technology is environmentally clean technology comparing with the previous conventional energy technologies and will play a key role to solve the greenhouse gas effect. Leading nations have increasingly focused on hydrogen technology R&D. This research is carried out the relative competitiveness of hydrogen energy technologies employed by an integrated fuzzy analytic hierarchy process (Fuzzy AHP) and The Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) approaches. We make four criteria, accounting for technological status, R&D budget, R&D human resource, and hydrogen infra. This research can be used as fundamental data for implementing national hydrogen energy R&D planning for energy policy-makers.

    Rufino, J.; Craveiro, J.; Schoofs, T.; Tatibana, C.; Windsor, J.


    The Integrated Modular Avionics and the ARINC 653 specifications are assuming a key role in the provision of a standard operating system interface for safety-critical applications in both the aeronautic and space markets. The AIR Technology, designed within the scope of an ESA initiative to develop a proof of concept, implements the notion of robust temporal and spatial partitioning. A different operating system kernel may be used per partition, furnishing the bare services to build the ARINC 653 application programming interface. This paper describes the advances done during AIR-II, an initiative to evolve the AIR Technology proof of concept towards an industrial product. Current prototype activities are based on RTEMS and on the SPARC V8 LEON3 processor and work is being done on the integration of Linux in the AIR Technology.

  16. Renewable generation technology choice and policies in a competitive electricity supply industry (United States)

    Sarkar, Ashok

    Renewable energy generation technologies have lower externality costs but higher private costs than fossil fuel-based generation. As a result, the choice of renewables in the future generation mix could be affected by the industry's future market-oriented structure because market objectives based on private value judgments may conflict with social policy objectives toward better environmental quality. This research assesses how renewable energy generation choices would be affected in a restructured electricity generation market. A multi-period linear programming-based model (Resource Planning Model) is used to characterize today's electricity supply market in the United States. The model simulates long-range (2000-2020) generation capacity planning and operation decisions under alternative market paradigms. Price-sensitive demand is used to simulate customer preferences in the market. Dynamically changing costs for renewables and a two-step load duration curve are used. A Reference Case represents the benchmark for a socially-optimal diffusion of renewables and a basis for comparing outcomes under alternative market structures. It internalizes externality costs associated with emissions of sulfur dioxide (SOsb2), nitrous oxides (NOsbx), and carbon dioxide (COsb2). A Competitive Case represents a market with many generation suppliers and decision-making based on private costs. Finally, a Market Power Case models the extreme case of market power: monopoly. The results suggest that the share of renewables would decrease (and emissions would increase) considerably in both the Competitive and the Market Power Cases with respect to the Reference Case. The reduction is greater in the Market Power Case due to pricing decisions under existing supply capability. The research evaluates the following environmental policy options that could overcome market failures in achieving an appropriate level of renewable generation: COsb2 emissions tax, SOsb2 emissions cap, renewable

  17. Overview of materials technologies for space nuclear power and propulsion (United States)

    Zinkle, S. J.; Ott, L. J.; Ingersoll, D. T.; Ellis, R. J.; Grossbeck, M. L.


    A wide range of different space nuclear systems are currently being evaluated as part of the DOE Special Purpose Fission Technology program. The near-term subset of systems scheduled to be evaluated range from 50 kWe gas-, pumped liquid metal-, or liquid metal heat pipe-cooled reactors for space propulsion to 3 kWe heat pipe or pumped liquid metal systems for Mars surface power applications. The current status of the materials technologies required for the successful development of near-term space nuclear power and propulsion systems is reviewed. Materials examined in this overview include fuels (UN, UO2, UZrH), cladding and structural materials (stainless steel, superalloys, refractory alloys), neutron reflector materials (Be, BeO), and neutron shield materials (B4C,LiH). The materials technologies issues are considerably less demanding for the 3 kWe reactor systems due to lower operating temperatures, lower fuel burnup, and lower radiation damage levels. A few reactor subcomponents in the 3 kWe reactors under evaluation are being used near or above their engineering limits, which may adversely affect the 5 to 10 year lifetime design goal. It appears that most of these issues for the 3 kWe reactor systems can be accommodated by incorporating a few engineering design changes. Design limits (temperature, burnup, stress, radiation levels) for the various materials proposed for space nuclear reactors will be summarized. For example, the temperature and stress limits for Type 316 stainless steel in the 3 kWe Na-cooled heat pipe reactor (Stirling engine) concept will be controlled by thermal creep and CO2 corrosion considerations rather than radiation damage issues. Conversely, the lower operating temperature limit for the LiH shield material will likely be defined by ionizing radiation damage (radiolysis)-induced swelling, even for the relatively low radiation doses associated with the 3 kWe reactor. .

    Pitman, C. L.; Erb, D. M.; Izygon, M. E.; Fridge, E. M., III; Roush, G. B.; Braley, D. M.; Savely, R. T.


    The United State's big space projects of the next decades, such as Space Station and the Human Exploration Initiative, will need the development of many millions of lines of mission critical software. NASA-Johnson (JSC) is identifying and developing some of the Computer Aided Software Engineering (CASE) technology that NASA will need to build these future software systems. The goal is to improve the quality and the productivity of large software development projects. New trends are outlined in CASE technology and how the Software Technology Branch (STB) at JSC is endeavoring to provide some of these CASE solutions for NASA is described. Key software technology components include knowledge-based systems, software reusability, user interface technology, reengineering environments, management systems for the software development process, software cost models, repository technology, and open, integrated CASE environment frameworks. The paper presents the status and long-term expectations for CASE products. The STB's Reengineering Application Project (REAP), Advanced Software Development Workstation (ASDW) project, and software development cost model (COSTMODL) project are then discussed.

    In this paper, we describe an integrated design space analysis approach consisting of full factorial layout generation, lithography simulations with added proximity effects, and rigorous statistical analysis through monte-carlo simulations which is used in the evaluating interconnects. This agile Design rule development process provides a quick turnaround time to down-select the potential layout configurations that can offer a competitive, robust and reliable design and manufacturing. Further layout and placement optimization is carried out to evaluate intra-cell, inter-cell and cell boundary situations, which are critical for a place and routed block. These interconnects developed using the integrated approach has been the key contributor to give 20-30% higher performance at the same Iddq leakage for 8T libraries compared to Single Diffusion break or Double Diffusion break based 12T libraries in 22FDX Technology.

Divisao de Energia Nuclear; Faria, Saulo M. de [Instituto Tecnologico de Aeronautica (ITA), Sao Jose dos Campos, SP (Brazil)


    For a few years now, the TERRA project is developing several technology pieces to foster nuclear space applications. In this way, a nuclear reactor concept has been developed as a first proposal. Together, the problem of heat to electricity conversion has been addressed. A closed Brayton cycle is being built and a Stirling machine is being worked out and perfected. In addition, two types of heat pipes are being look at. One related with high temperature made of Mo13Re, an especial alloy. And a second one made of copper, which mainly could be used as a passive heat rejection. In this way, all major areas of interest in a micro station to be used in space has been addressed. A new passive technology has been inferred and is related with Tesla turbine or its evolution, known as multi fluid passive turbine. This technology has the potential to either: improve the Brayton cycle or its efficiency. In this paper, some details are discussed and some will be shown during the presentation, as the work evolve.

  2. Terrestrial Micro Renewable Energy Applications of Space Technology (United States)

    Komerath, N. M.; Komerath, P. P.

    This paper explores the synergy between technologies intended for extraterrestrial in situ resource utilization and those for terrestrial mass-market micro renewable power generation systems. The case for a micro renewable energy architecture is presented. The obstacles hindering market success are summarized, along with opportunities from recent demonstrations suggesting that the public appetite for sophisticated technology worldwide may be underappreciated by technical researchers. Technical innovations from space research are summarized along with estimates of possible conversion efficiencies. It is argued that the cost-effectiveness of micro power generation must be viewed through the value of the first few watts of available power, rather than the marginal cost per kilowatt-hour of electric power from utility power grids. This leads to the finding that the actual target cost per unit power, and efficiency, are well within reach of space technology products. Hybrid systems integrating power extraction from multiple resources, and adaptable for multiple applications, can break through mass market price barriers. Recent work to develop learning resources and test beds as part of a Micro Renewable Energy Laboratory is summarized.

  3. Extreme Environment Technologies for Space and Terrestrial Applications (United States)

    Balint, Tibor S.; Cutts, James A.; Kolawa, Elizabeth A.; Peterson, Craig E.


    Over the next decades, NASA's planned solar system exploration missions are targeting planets, moons and small bodies, where spacecraft would be expected to encounter diverse extreme environmental (EE) conditions throughout their mission phases. These EE conditions are often coupled. For instance, near the surface of Venus and in the deep atmospheres of giant planets, probes would experience high temperatures and pressures. In the Jovian system low temperatures are coupled with high radiation. Other environments include thermal cycling, and corrosion. Mission operations could also introduce extreme conditions, due to atmospheric entry heat flux and deceleration. Some of these EE conditions are not unique to space missions; they can be encountered by terrestrial assets from the fields of defense,oil and gas, aerospace, and automotive industries. In this paper we outline the findings of NASA's Extreme Environments Study Team, including discussions on state of the art and emerging capabilities related to environmental protection, tolerance and operations in EEs. We will also highlight cross cutting EE mitigation technologies, for example, between high g-load tolerant impactors for Europa and instrumented projectiles on Earth; high temperature electronics sensors on Jupiter deep probes and sensors inside jet engines; and pressure vessel technologies for Venus probes and sea bottom monitors. We will argue that synergistic development programs between these fields could be highly beneficial and cost effective for the various agencies and industries. Some of these environments, however, are specific to space and thus the related technology developments should be spear headed by NASA with collaboration from industry and academia.

  6. On-Orbit Measurement of Next Generation Space Solar Cell Technology on the International Space Station (United States)

    Wolford, David S.; Myers, Matthew G.; Prokop, Norman F.; Krasowski, Michael J.; Parker, David S.; Cassidy, Justin C.; Davies, William E.; Vorreiter, Janelle O.; Piszczor, Michael F.; McNatt, Jeremiah S.


    Measurement is essential for the evaluation of new photovoltaic (PV) technology for space solar cells. NASA Glenn Research Center (GRC) is in the process of measuring several solar cells in a supplemental experiment on NASA Goddard Space Flight Center's (GSFC) Robotic Refueling Mission's (RRM) Task Board 4 (TB4). Four industry and government partners have provided advanced PV devices for measurement and orbital environment testing. The experiment will be on-orbit for approximately 18 months. It is completely self-contained and will provide its own power and internal data storage. Several new cell technologies including four- junction (4J) Inverted Metamorphic Multijunction (IMM) cells will be evaluated and the results compared to ground-based measurements.

    Decker, D. K.; Cannady, M. D.; Cassinelli, J. E.; Farber, B. F.; Lurie, C.; Fleck, G. W.; Lepisto, J. W.; Massner, A.; Ritterman, P. F.


    The multihundred kilowatt electrical power aspects of a mannable space platform in low Earth orbit is analyzed from a cost and technology viewpoint. At the projected orbital altitudes, Shuttle launch and servicing are technically and economically viable. Power generation is specified as photovoltaic consistent with projected planning. The cost models and trades are based upon a zero interest rate (the government taxes concurrently as required), constant dollars (1980), and costs derived in the first half of 1980. Space platform utilization of up to 30 years is evaluated to fully understand the impact of resupply and replacement as satellite missions are extended. Such lifetimes are potentially realizable with Shuttle servicing capability and are economically desirable.

  8. Developing hybrid near-space technologies for affordable access to suborbital space (United States)

    Badders, Brian David

    High power rockets and high altitude balloons are two near-space technologies that could be combined in order to provide access to the mesosphere and, eventually, suborbital space. This "rockoon" technology has been used by several large budget space programs before being abandoned in favor of even more expensive, albeit more accurate, ground launch systems. With the increased development of nano-satellites and atmospheric sensors, combined with rising interest in global atmospheric data, there is an increase in desire for affordable access to extreme altitudes that does not necessarily require the precision of ground launches. Development of hybrid near-space technologies for access to over 200k ft. on a small budget brings many challenges within engineering, systems integration, cost analysis, market analysis, and business planning. This research includes the design and simulation testing of all the systems needed for a safe and reusable launch system, the cost analysis for initial production, the development of a business plan, and the development of a marketing plan. This project has both engineering and scientific significance in that it can prove the space readiness of new technologies, raise their technology readiness levels (TRLs), expedite the development process, and also provide new data to the scientific community. It also has the ability to stimulate university involvement in the aerospace industry and help to inspire the next generation of workers in the space sector. Previous development of high altitude balloon/high power rocket hybrid systems have been undertaken by government funded military programs or large aerospace corporations with varying degrees of success. However, there has yet to be a successful flight with this type of system which provides access to the upper mesosphere in a university setting. This project will aim to design and analyze a viable system while testing the engineering process under challenging budgetary constraints. The

    Krabach, Timothy


    Some of the many new and advanced exploration technologies which will enable space missions in the 21st century and specifically the Manned Mars Mission are explored in this presentation. Some of these are the system on a chip, the Computed-Tomography imaging Spectrometer, the digital camera on a chip, and other Micro Electro Mechanical Systems (MEMS) technology for space. Some of these MEMS are the silicon micromachined microgyroscope, a subliming solid micro-thruster, a micro-ion thruster, a silicon seismometer, a dewpoint microhygrometer, a micro laser doppler anemometer, and tunable diode laser (TDL) sensors. The advanced technology insertion is critical for NASA to decrease mass, volume, power and mission costs, and increase functionality, science potential and robustness.

  12. Competitiveness, innovation and democracy. Space for clean energy within electricity reforms

    Energy Technology Data Exchange (ETDEWEB)

    Alfaro, L.V.


    This thesis presents an exploratory analysis about the institutional factors affecting the reforms of the eletricity sector in developing countries. In particular the thesis researches the process of technology selection and the factors and incentives affecting the choice between clean and unclean technologies. The co-evolutionary character of technological and institutional aspects are studied within a focus on the Costa Rican experience. Empirical evidence from the clustering process developed in Costa Rica is examined and an analytical framework is developed for a clearer understanding of the reforms that constrain the use of clean energy. The research presented here has shown the co-evolutionary character of technological and institutional selection processes, and how both influence the particular path where technology selection is defined. It has been also found that the specific institutional framework in developing countries that supports the governance mechanisms is a crucial factor when explaining technological specialisation as well as the performance of the sector, at the national level. Among the main factors within the local institutional framework, it has been found that ownership structure and market architecture as well as the governmental regulatory framework are essential elements explaining the governance structure, and to some extent, technology selection in the electricity sector. Those factors are the rules of the game by which producers define the specific technology to be implemented. (au)

    Anderson, J. B.; Coleman, A. D.; Driskill, T. C.; Lindell, M. C.

    This paper presents the results of the modal survey test of the Lidar In-space Technology Experiment (LITE), a Space Shuttle payload mounted in a Spacelab flight single pallet. The test was performed by the Dynamics Test Branch at Marshall Space Flight Center, AL and run in two phases. In the first phase, an unloaded orthogrid connected to the pallet with 52 tension struts was tested. This test included 73 measurement points in three directions. In the second phase, the pallet was integrated with mass simulators mounted on the flight support structure to represent the dynamics (weight and center of gravity) of the various components comprising the LITE experiment and instrumented at 213 points in 3 directions. The test article was suspended by an air bag system to simulate a free-free boundary condition. This paper presents the results obtained from the testing and analytical model correlation efforts. The effect of the suspension system on the test article is also discussed.

    Chang, Chengwu; Huang, Huiming; Liu, Hongyang; Gao, Shenghua; Cheng, Liyu


    Since the 21st century, Spatial laser communication has made a breakthrough development. Europe, the United States, Japan and other space powers have carried out the test of spatial laser communication technology on-orbit, and put forward a series of plans. In 2011, China made the first technology demonstration of satellite-ground laser communication carried by HY-2 satellite. Nowadays, in order to improve the transmission rate of spatial network, the topic of spatial laser communication network is becoming a research hotspot at home and abroad. This thesis, from the basic problem of spatial laser communication network to solve, analyzes the main difference between spatial network and ground network, which draws forth the key technology of spatial laser communication backbone network, and systematically introduces our research on aggregation, addressing, architecture of spatial network. From the perspective of technology development status and trends, the thesis proposes the development route of spatial laser communication network in stages. So as to provide reference about the development of spatial laser communication network in China.

  16. Tumor evolution in space: the effects of competition colonization tradeoffs on tumor invasion dynamics

    Directory of Open Access Journals (Sweden)

    Paul A Orlando


    Full Text Available We apply competition colonization tradeoff models to tumor growth and invasion dynamics to explore the hypothesis that varying selection forces will result in predictable phenotypic differences in cells at the tumor invasive front compared to those in the core. Spatially, ecologically, and evolutionarily explicit partial differential equation models of tumor growth confirm that spatial invasion produces selection pressure for motile phenotypes. The effects of the invasive phenotype on normal adjacent tissue determine the patterns of growth and phenotype distribution. If tumor cells do not destroy their environment, colonizer and competitive phenotypes coexist with the former localized at the invasion front and the latter, to the tumor interior. If tumors cells do destroy their environment, then cell motility is strongly selected resulting in accelerated invasion speed with time. Our results suggest that the widely observed genetic heterogeneity within cancers may not be the stochastic effect of random mutations. Rather, it may be the consequence of predictable variations in environmental selection forces and corresponding phenotypic adaptations.

  18. Application of dexterous space robotics technology to myoelectric prostheses (United States)

    Hess, Clifford; Li, Larry C. H.; Farry, Kristin A.; Walker, Ian D.


    Future space missions will require robots equipped with highly dexterous robotic hands to perform a variety of tasks. A major technical challenge in making this possible is an improvement in the way these dexterous robotic hands are remotely controlled or teleoperated. NASA is currently investigating the feasibility of using myoelectric signals to teleoperate a dexterous robotic hand. In theory, myoelectric control of robotic hands will require little or no mechanical parts and will greatly reduce the bulk and weight usually found in dexterous robotic hand control devices. An improvement in myoelectric control of multifinger hands will also benefit prosthetics users. Therefore, as an effort to transfer dexterous space robotics technology to prosthetics applications and to benefit from existing myoelectric technology, NASA is collaborating with the Limbs of Love Foundation, the Institute for Rehabilitation and Research, and Rice University in developing improved myoelectric control multifinger hands and prostheses. In this paper, we will address the objectives and approaches of this collaborative effort and discuss the technical issues associated with myoelectric control of multifinger hands. We will also report our current progress and discuss plans for future work.

  19. Integration of advanced teleoperation technologies for control of space robots (United States)

    Stagnaro, Michael J.


    Teleoperated robots require one or more humans to control actuators, mechanisms, and other robot equipment given feedback from onboard sensors. To accomplish this task, the human or humans require some form of control station. Desirable features of such a control station include operation by a single human, comfort, and natural human interfaces (visual, audio, motion, tactile, etc.). These interfaces should work to maximize performance of the human/robot system by streamlining the link between human brain and robot equipment. This paper describes development of a control station testbed with the characteristics described above. Initially, this testbed will be used to control two teleoperated robots. Features of the robots include anthropomorphic mechanisms, slaving to the testbed, and delivery of sensory feedback to the testbed. The testbed will make use of technologies such as helmet mounted displays, voice recognition, and exoskeleton masters. It will allow tor integration and testing of emerging telepresence technologies along with techniques for coping with control link time delays. Systems developed from this testbed could be applied to ground control of space based robots. During man-tended operations, the Space Station Freedom may benefit from ground control of IVA or EVA robots with science or maintenance tasks. Planetary exploration may also find advanced teleoperation systems to be very useful.

  20. NASA's Space Environments and Effects (SEE) Program: The Pursuit of Tomorrow's Space Technology (United States)

    Pearson, Steven D.; Hardage, Donna M.


    A hazard to all spacecraft orbiting the earth and exploring the unknown in deep space is the existence of a harsh and ever changing environment with its subsequent effects. Some of these environmental hazards, such as plasma, extreme thermal excursions, meteoroids, and ionizing radiation result from natural sources, whereas others, such as orbital debris and neutral contamination are induced by the presence of spacecraft themselves. The subsequent effects can provide damaging or even disabling effects on spacecraft, its materials, and its instruments. In partnership with industry, academia, and other government agencies, National Aeronautics & Space Administration's (NASA's) Space Environments & Effects (SEE) Program defines the space environments and advocates technology development to accommodate or mitigate these harmful environments on the spacecraft. This program provides a very comprehensive and focused approach to understanding the space environment, to define the best techniques for both flight and ground-based experimentation, to update the models which predict both the environments and the environmental effects on spacecraft, and finally to ensure that this information is properly maintained and inserted into spacecraft design programs. This paper will provide an overview of the Program's purpose, goals, database management and technical activities. In particular, the SEE Program has been very active in developing improved ionizing radiation models and developing related flight experiments which should aid in determining the effect of the radiation environment on modern electronics.

  1. The Science and Technology of Future Space Missions (United States)

    Bonati, A.; Fusi, R.; Longoni, F.


    The future space missions span over a wide range of scientific objectives. After different successful scientific missions, other international cornerstone experiments are planned to study of the evolution of the universe and of the primordial stellar systems, and our solar system. Space missions for the survey of the microwave cosmic background radiation, deep-field search in the near and mid-infrared region and planetary exploration will be carried out. Several fields are open for research and development in the space business. Three major categories can be found: detector technology in different areas, electronics, and software. At LABEN, a Finmeccanica Company, we are focusing the technologies to respond to this challenging scientific demands. Particle trackers based on silicon micro-strips supported by lightweight structures (CFRP) are studied. In the X-ray field, CCD's are investigated with pixels of very small size so as to increase the spatial resolution of the focal plane detectors. High-efficiency and higly miniaturized high-voltage power supplies are developed for detectors with an increasingly large number of phototubes. Material research is underway to study material properties at extreme temperatures. Low-temperature mechanical structures are designed for cryogenic ( 20 K) detectors in order to maintain the high precision in pointing the instrument. Miniaturization of front end electronics with low power consumption and high number of signal processing channels is investigated; silicon-based microchips (ASIC's) are designed and developed using state-of-the-art technology. Miniaturized instruments to investigate the planets surface using X-Ray and Gamma-Ray scattering techniques are developed. The data obtained from the detectors have to be processed, compressed, formatted and stored before their transmission to ground. These tasks open up additional strategic areas of development such as microprocessor-based electronics for high-speed and parallel data

  2. Logistics Reduction and Repurposing Technology for Long Duration Space Missions (United States)

    Broyan, James L.; Chu, Andrew; Ewert, Michael K.


    One of NASA's Advanced Exploration Systems (AES) projects is the Logistics Reduction and Repurposing (LRR) project, which has the goal of reducing logistics resupply items through direct and indirect means. Various technologies under development in the project will reduce the launch mass of consumables and their packaging, enable reuse and repurposing of items and make logistics tracking more efficient. Repurposing also reduces the trash burden onboard spacecraft and indirectly reduces launch mass by replacing some items on the manifest. Examples include reuse of trash as radiation shielding or propellant. This paper provides the status of the LRR technologies in their third year of development under AES. Advanced clothing systems (ACS) are being developed to enable clothing to be worn longer, directly reducing launch mass. ACS has completed a ground exercise clothing study in preparation for an International Space Station (ISS) technology demonstration in 2014. Development of launch packaging containers and other items that can be repurposed on-orbit as part of habitation outfitting has resulted in a logistics-to-living (L2L) concept. L2L has fabricated and evaluated several multi-purpose cargo transfer bags (MCTBs) for potential reuse on orbit. Autonomous logistics management (ALM) is using radio frequency identification (RFID) to track items and thus reduce crew requirements for logistics functions. An RFID dense reader prototype is under construction and plans for integrated testing are being made. Development of a heat melt compactor (HMC) second generation unit for processing trash into compact and stable tiles is nearing completion. The HMC prototype compaction chamber has been completed and system development testing is underway. Research has been conducted on the conversion of trash-to-gas (TtG) for high levels of volume reduction and for use in propulsion systems. A steam reformation system was selected for further system definition of the TtG technology

  3. VZLUSAT-1: verification of new materials and technologies for space (United States)

    Daniel, Vladimir; Urban, Martin; Nentvich, Ondrej; Stehlikova, Veronika


    CubeSats are a good opportunity to test new technologies and materials on orbit. These innovations can be later used for improving of properties and life length of Cubesat or other satellites as well. VZLUSAT-1 is a small satellite from the CubeSat family, which will carry a wide scale of payloads with different purposes. The poster is focused on measuring of degradation and properties measurement of new radiation hardened composite material in orbit due to space environment. Material properties changes can be studied by many methods and in many disciplines. One payload measures mechanical changes in dependence on Young's modulus of elasticity which is got from non-destructive testing by mechanical vibrations. The natural frequencies we get using Fast Fourier Transform. The material is tested also by several thermometers which measure heat distribution through the composite, as well as reflectivity in dependence on different coatings. The satellite also will measure the material radiation shielding properties. There are PIN diodes which measure the relative shielding efficiency of composite and how it will change in time in space environment. Last one of material space testing is measurement of outgassing from tested composite material. It could be very dangerous for other parts of satellite, like detectors, when anything was outgassing, for example water steam. There are several humidity sensors which are sensitive to steam and other gases and measures temperatures as well.

  4. Solar concentrator technology development for space based applications, volume 1 (United States)

    Pintz, A.; Castle, C. H.; Reimer, R. R.


    Thermoelectric conversion using a radio-isotope heat source has been used where outer planetary space craft are too far away for absorbing significant solar energy. Solar dynamic power (SDP) conversion is one technology that offers advantages for applications within the inner planet region. Since SDP conversion efficiency can be 2 to 3 times higher than photovoltaic, the collecting surfaces are much reduced in area and therefore lighter. This becomes an advantage in allocating more weight to launched payloads. A second advantage results for low earth orbit applications. The reduced area results in lower drag forces on the spacecraft and requires less reboost propellant to maintain orbit. A third advantage occurs because of the sun-to-shade cycling while in earth orbit. Photovoltaic systems require batteries to store energy for use when in the shade, and battery life for periods of 10 to 15 years is not presently achievable. For these reasons the Solar Dynamics and Thermal Systems Branch at NASA LeRC has funded work in developing SDP systems. The generic SDP system uses a large parabolic solar concentrator to focus solar energy onto a power conversion device. The concentrators are large areas and must therefore be efficient and have low specific weights. Yet these surfaces must be precise and capable of being stowed in a launch vehicle and then deployed and sometimes unfurled in space. There are significant technical challenges in engineering such structures, and considerable investigation has been made to date. This is the first of two volumes reporting on the research done by the Advanced Manufacturing Center at Cleveland State University to assist NASA LeRC in evaluating this technology. The objective of the grant was to restore the solar concentrator development technology of the 1960s while improving it with advances that have occurred since then. This report summarizes the work done from January 1989 through December 1991.

  6. Augmenting Space Technology Program Management with Secure Cloud & Mobile Services (United States)

    Hodson, Robert F.; Munk, Christopher; Helble, Adelle; Press, Martin T.; George, Cory; Johnson, David


    The National Aeronautics and Space Administration (NASA) Game Changing Development (GCD) program manages technology projects across all NASA centers and reports to NASA headquarters regularly on progress. Program stakeholders expect an up-to-date, accurate status and often have questions about the program's portfolio that requires a timely response. Historically, reporting, data collection, and analysis were done with manual processes that were inefficient and prone to error. To address these issues, GCD set out to develop a new business automation solution. In doing this, the program wanted to leverage the latest information technology platforms and decided to utilize traditional systems along with new cloud-based web services and gaming technology for a novel and interactive user environment. The team also set out to develop a mobile solution for anytime information access. This paper discusses a solution to these challenging goals and how the GCD team succeeded in developing and deploying such a system. The architecture and approach taken has proven to be effective and robust and can serve as a model for others looking to develop secure interactive mobile business solutions for government or enterprise business automation.

  7. Technological Innovation and Competitiveness in The Global Economy: India's Changing Status and Its Implications

    Directory of Open Access Journals (Sweden)

    Bala Subrahmanya Mungila Hillemane


    Full Text Available   This paper probes the changing innovation status and resultant competitiveness in the context of global economy and questions the recent ranking improvements of India on the basis of hard economic facts. This paper has made use of secondary data comprising innovation indices and competitiveness rankings published by international organizations and reputed business schools from time to time since 1996 to analyze the changing status of India internationally. Later, using secondary data on key macro-economic variables published by the Government of India, the recent ranking of India is closely examined as well as recent steps taken by the government of India to improve competitiveness is elaborated. The study throws light on the changing but improving innovation dimensions and competitiveness ranking of India since 1996 till 2010. From nowhere India emerges and occupies the second slot, after China, in the global competitiveness ranking. But hard core macro-economic variables do not justify India’s elevation to the top in any way. Given this, the study throws light on the recent policy measures announced by the Government of India and its implications as well as policy imperatives.

    Ray F. Iunius


    Full Text Available Several challenges regarding the European tourism industry were recently identified at EU level which the experts of the European Commission tried to meet, thus formulating several priorities within the newest Tourism Action Framework: Stimulate long-term competitiveness in the European tourism sector, promote the development of sustainable and high-quality tourism, and consolidate the image and promotion of European tourist destinations. Due to the new generational context, information and communications technology ICT and innovation became keywords within the most recent European Tourism Policy. Considering the symbiotic relationship that exists at the European tourism level between sustainable development, innovative ICT solutions, and long-term competitiveness, the decision-makers in European destinations should focus on identifying innovative ways to implement the new Tourism Action Framework adopted by the European Commission, through ICT applications, in order to support long-term competitiveness achievement. Two such authentic proposals are formulated within the present discussion paper: the creation of a decision support system for the management of sustainable European destinations and the development of a trip-planner for quality-sensitive tourists based on an umbrella European certification/labeling system for tourism quality. There is still a fertile field in these areas and, therefore, more innovative ICT tools to support the long-term competitiveness of European tourist destinations can be developed.

    Borth, F.C. III; Thompson, J.W.; Mishaga, J.M.


    Through ComEd Fossil (Generating) Division's Competitive Action Plan (CAP) evaluation changes have been identified which are necessary to improve generating station performance. These changes are intended to improve both station reliability and financial margins, and are essential for stations to be successful in a competitive marketplace. Plant upgrades, advanced equipment stewardship, and personnel reductions have been identified as necessary steps in achieving industry leadership and competitive advantage. To deal effectively with plant systems and contend in the competitive marketplace Information Technology (IT) solutions to business problems are being developed. Data acquisition, storage, and retrieval are being automated through use of state-of-the-art Data Historians. Total plant, high resolution, long term process information will be accessed through Local/Wide Area Networks (LAN/WAN) connections from desktop PC's. Generating unit Thermal Performance Monitors accessing the Data Historian will analyze plant and system performance enabling reductions in operating costs, and improvements in process control. As inputs to proactive maintenance toolsets this data allows anticipation of equipment service needs, advanced service scheduling, and cost/benefit analysis. The ultimate goal is to optimize repair needs with revenue generation. Advanced applications building upon these foundations will bring knowledge of the costs associated with all the products a generating station offers its customer(s). An overall design philosophy along with preliminary results is presented; these results include shortfalls, lessons learned, and future options

  11. HI-STAR. Health Improvements Through Space Technologies and Resources: Final Report (United States)

    Finarelli, Margaret G.


    The purpose of this document is to describe a global strategy to integrate the use of space technology in the fight against malaria. Given the well-documented relationship between the vector and its environment, and the ability of existing space technologies to monitor environmental factors, malaria is a strong candidate for the application of space technology. The concept of a malaria early warning system has been proposed in the past' and pilot studies have been conducted. The HI-STAR project (Health Improvement through Space Technologies and Resources) seeks to build on this concept and enhance the space elements of the suggested framework. As such, the mission statement for this International Space University design project has been defined as follows: "Our mission is to develop and promote a global strategy to help combat malaria using space technology". A general overview of malaria, aspects of how space technology can be useful, and an outline of the HI-STAR strategy is presented.

  12. Activities of JAXA's Innovative Technology Center on Space Debris Observation (United States)

    Yanagisawa, T.; Kurosaki, H.; Nakajima, A.

    The innovative technology research center of JAXA is developing observational technologies for GEO objects in order to cope with the space debris problem. The center had constructed the optical observational facility for space debris at Mt. Nyukasa, Nagano in 2006. As observational equipments such as CCD cameras and telescopes were set up, the normal observation started. In this paper, the detail of the facilities and its activities are introduced. The observational facility contains two telescopes and two CCD cameras. The apertures of the telescopes are 35cm and 25 cm, respectively. One CCD camera in which 2K2K chip is installed can observe a sky region of 1.3 times 1.3-degree using the 35cm telescope. The other CCD camera that contains two 4K2K chips has an ability to observe 2.6 times 2.6-degree's region with the 25cm telescope. One of our main objectives is to detect faint GEO objects that are not catalogued. Generally, the detection limit of GEO object is determined by the aperture of the telescope. However, by improving image processing techniques, the limit may become low. We are developing some image processing methods that use many CCD frames to detect faint objects. We are trying to use FPGA (Field Programmable Gate Array) system to reduce analyzing time. By applying these methods to the data taken by a large telescope, the detection limit will be significantly lowered. The orbital determination of detected GEO debris is one of the important things to do. Especially, the narrow field view of an optical telescope hinders us from re-detection of the GEO debris for the orbital determination. Long observation time is required for one GEO object for the orbital determination that is inefficient. An effective observation strategy should be considered. We are testing one observation method invented by Umehara that observes one inertia position in the space. By observing one inertia position for two nights, a GEO object that passed through the position in the

  13. Logistics Reduction and Repurposing Technology for Long Duration Space Missions (United States)

    Broyan, James Lee, Jr.; Chu, Andrew; Ewert, Michael K.


    One of NASA's Advanced Exploration Systems (AES) projects is the Logistics Reduction and Repurposing (LRR) project, which has the goal of reducing logistics resupply items through direct and indirect means. Various technologies under development in the project will reduce the launch mass of consumables and their packaging, enable reuse and repurposing of items, and make logistics tracking more efficient. Repurposing also reduces the trash burden onboard spacecraft and indirectly reduces launch mass by one manifest item having two purposes rather than two manifest items each having only one purpose. This paper provides the status of each of the LRR technologies in their third year of development under AES. Advanced clothing systems (ACSs) are being developed to enable clothing to be worn longer, directly reducing launch mass. ACS has completed a ground exercise clothing study in preparation for an International Space Station technology demonstration in 2014. Development of launch packaging containers and other items that can be repurposed on-orbit as part of habitation outfitting has resulted in a logistics-to-living (L2L) concept. L2L has fabricated and evaluated several multi-purpose cargo transfer bags for potential reuse on-orbit. Autonomous logistics management is using radio frequency identification (RFID) to track items and thus reduce crew time for logistics functions. An RFID dense reader prototype is under construction and plans for integrated testing are being made. A heat melt compactor (HMC) second generation unit for processing trash into compact and stable tiles is nearing completion. The HMC prototype compaction chamber has been completed and system development testing is under way. Research has been conducted on the conversion of trash-to-gas (TtG) for high levels of volume reduction and for use in propulsion systems. A steam reformation system was selected for further system definition of the TtG technology.

    Directory of Open Access Journals (Sweden)

    Antônio D. C. Jesus


    Full Text Available We present a study of collisional dynamics between space debris and an operational vehicle in LEO. We adopted an approach based on the relative dynamics between the objects on a collisional course and with a short warning time and established a semianalytical solution for the final trajectories of these objects. Our results show that there are angular ranges in 3D, in addition to the initial conditions, that favor the collisions. These results allowed the investigation of a range of technological parameters for the spacecraft (e.g., fuel reserve that allow a safe evasive maneuver (e.g., time available for the maneuver. The numerical model was tested for different values of the impact velocity and relative distance between the approaching objects.

  4. Super Global Projects and Environmentally Friendly Technologies Used in Space Exploration: Realities and Prospects of the Space Age

    Directory of Open Access Journals (Sweden)

    Sergey Krichevsky


    Full Text Available The 60th anniversary of the Space Age is an important intermediate finishing point on the way of a man and the whole humanity to space. Along with the outstanding achievements, there are a number of challenges and contradictions in space exploration due to the aggravation of the global crisis on Earth, low efficiency and the backlog of space research in the transition to a new technology based reality and clean technologies. Both the international astronautics and the space exploration area nowadays face difficulties in choosing a new paradigm and a development strategy that is becoming even more complicated due to the current unstable and turbulent situation on Earth. The article reveals the optimistic scenario of further space exploration, as well as the methodological and practical aspects of new projects and technologies. The periodization of the Space Age history has been conducted. It has been also proposed a new classification of the “space” phenomenon due to concretizing the concept of “global” in the form of a three-scale structure encompassing the following levels: 1 planetary global; 2 super global; 3 universally global. The notion of “super global space exploration project” has been introduced. The concept of further space exploration is proposed, which includes four interrelated super global projects:1 Earth Protection System from Asteroid and Comet Threat; 2 Moon Exploration; 3 Mars Exploration; 4 Cosmic Humanity. Since the humanity is embarking on the practical implementation of these super global projects, it is urgent to make a transition towards a new technology based order, as well as up-to-date technologies. A couple of ecological projects and space exploration technologies of the 20th and 21st centuries have been exemplified and analyzed. It has been also worked out the list of new environmentally friendly space technologies and projects. The research makes an emphasis upon a great potential of clean and green

  6. A new space technology for ocean observation: the SMOS mission

    Directory of Open Access Journals (Sweden)

    Jordi Font


    Full Text Available Capability for sea surface salinity observation was an important gap in ocean remote sensing in the last few decades of the 20th century. New technological developments during the 1990s at the European Space Agency led to the proposal of SMOS (Soil Moisture and Ocean Salinity, an Earth explorer opportunity mission based on the use of a microwave interferometric radiometer, MIRAS (Microwave Imaging Radiometer with Aperture Synthesis. SMOS, the first satellite ever addressing the observation of ocean salinity from space, was successfully launched in November 2009. The determination of salinity from the MIRAS radiometric measurements at 1.4 GHz is a complex procedure that requires high performance from the instrument and accurate modelling of several physical processes that impact on the microwave emission of the ocean’s surface. This paper introduces SMOS in the ocean remote sensing context, and summarizes the MIRAS principles of operation and the SMOS salinity retrieval approach. It describes the Spanish SMOS high-level data processing centre (CP34 and the SMOS Barcelona Expert Centre on Radiometric Calibration and Ocean Salinity (SMOS-BEC, and presents a preliminary validation of global sea surface salinity maps operationally produced by CP34.

  7. Leveraging Quick Response Code Technology to Facilitate Simulation-Based Leaderboard Competition. (United States)

    Chang, Todd P; Doughty, Cara B; Mitchell, Diana; Rutledge, Chrystal; Auerbach, Marc A; Frisell, Karin; Jani, Priti; Kessler, David O; Wolfe, Heather; MacKinnon, Ralph J; Dewan, Maya; Pirie, Jonathan; Lemke, Daniel; Khattab, Mona; Tofil, Nancy; Nagamuthu, Chenthila; Walsh, Catharine M


    Leaderboards provide feedback on relative performance and a competitive atmosphere for both self-guided improvement and social comparison. Because simulation can provide substantial quantitative participant feedback, leaderboards can be used, not only locally but also in a multidepartment, multicenter fashion. Quick Response (QR) codes can be integrated to allow participants to access and upload data. We present the development, implementation, and initial evaluation of an online leaderboard employing principles of gamification using points, badges, and leaderboards designed to enhance competition among healthcare providers. This article details the fundamentals behind the development and implementation of a user-friendly, online, multinational leaderboard that employs principles of gamification to enhance competition and integrates a QR code system to promote both self-reporting of performance data and data integrity. An open-ended survey was administered to capture perceptions of leaderboard implementation. Conceptual step-by-step instructions detailing how to apply the QR code system to any leaderboard using simulated or real performance metrics are outlined using an illustrative example of a leaderboard that employed simulated cardiopulmonary resuscitation performance scores to compare participants across 17 hospitals in 4 countries for 16 months. The following three major descriptive categories that captured perceptions of leaderboard implementation emerged from initial evaluation data from 10 sites: (1) competition, (2) longevity, and (3) perceived deficits. A well-designed leaderboard should be user-friendly and encompass best practices in gamification principles while collecting and storing data for research analyses. Easy storage and export of data allow for longitudinal record keeping that can be leveraged both to track compliance and to enable social competition.

  9. Localization of epidural space: A review of available technologies. (United States)

    Elsharkawy, Hesham; Sonny, Abraham; Chin, Ki Jinn


    Although epidural analgesia is widely used for pain relief, it is associated with a significant failure rate. Loss of resistance technique, tactile feedback from the needle, and surface landmarks are traditionally used to guide the epidural needle tip into the epidural space (EDS). The aim of this narrative review is to critically appraise new and emerging technologies for identification of EDS and their potential role in the future. The PubMed, Cochrane Central Register of Controlled Clinical Studies, and Web of Science databases were searched using predecided search strategies, yielding 1048 results. After careful review of abstracts and full texts, 42 articles were selected to be included. Newer techniques for localization of EDS can be broadly classified into techniques that (1) guide the needle to the EDS, (2) identify needle entry into the EDS, and (3) confirm catheter location in EDS. An ideal method should be easy to learn and perform, easily reproducible with high sensitivity and specificity, identifies inadvertent intrathecal and intravascular catheter placements with ease, feasible in perioperative setting and have a cost-benefit advantage. Though none of them in their current stages of development qualify as an ideal method, many show tremendous potential. Some techniques are useful in patients with difficult spinal anatomy and infants, and thus are complementary to traditional methods. In addition to improving the existing technology, future research should aim at proving the superiority of these techniques over traditional methods, specifically regarding successful EDS localization, better safety profile, and a favorable cost-benefit ratio.

  11. Space technology for directly imaging and characterizing exo-Earths (United States)

    Crill, Brendan P.; Siegler, Nicholas


    The detection of Earth-like exoplanets in the habitable zone of their stars, and their spectroscopic characterization in a search for biosignatures, requires starlight suppression that exceeds the current best ground-based performance by orders of magnitude. The required planet/star brightness ratio of order 10-10 at visible wavelengths can be obtained by blocking stellar photons with an occulter, either externally (a starshade) or internally (a coronagraph) to the telescope system, and managing diffracted starlight, so as to directly image the exoplanet in reflected starlight. Coronagraph instruments require advancement in telescope aperture (either monolithic or segmented), aperture obscurations (obscured by secondary mirror and its support struts), and wavefront error sensitivity (e.g. line-of-sight jitter, telescope vibration, polarization). The starshade, which has never been used in a science application, benefits a mission by being decoupled from the telescope, allowing a loosening of telescope stability requirements. In doing so, it transfers the difficult technology from the telescope system to a large deployable structure (tens of meters to greater than 100 m in diameter) that must be positioned precisely at a distance of tens of thousands of kilometers from the telescope. We describe in this paper a roadmap to achieving the technological capability to search for biosignatures on an Earth-like exoplanet from a future space telescope. Two of these studies, HabEx and LUVOIR, include the direct imaging of Earth-sized habitable exoplanets as a central science theme.

  19. CSR and technology companies: A study on its implementation, integration and effects on the competitiveness of companies

    Directory of Open Access Journals (Sweden)

    Juan Andres Bernal-Conesa


    Full Text Available Purpose: In this paper, a structural equation model is presented in order to explain the motivations of implementing Corporate Social Responsibility (CSR in Spanish technology companies and its linkage with others standardized management systems before CSR implementation. It also examines whether CSR influences the competitiveness of these companies. Design/methodology/approach: The study was conducted in companies located in Spanish Science and Technology Parks. For this study, a survey was sent and structural equation model was used. Findings and Originality/value: Model results show that there is a positive, direct and statistically significant relationship between the motivations, previous management systems, implementation of CSR and the real integration of CSR in the organization. Research limitations/implications: Limitations are determined by the technique used for the proposed model: structural equations, which assume linearity of the relationship between latent variables. Practical implications: Companies can use the results of this study as a foothold to enhance the integration of CSR based on previous management systems and take advantage of synergies between them, since the integration of CSR has a direct relationship with the competitiveness of the company. Originality/value: The link between the motivations of CSR, CSR actions and their integration in technology companies are reliably and empirically demonstrated.

  20. Managing the natural disasters from space technology inputs (United States)

    Jayaraman, V.; Chandrasekhar, M. G.; Rao, U. R.


    Natural disasters, whether of meteorological origin such as Cyclones, Floods, Tornadoes and Droughts or of having geological nature such as earthquakes and volcanoes, are well known for their devastating impacts on human life, economy and environment. With tropical climate and unstable land forms, coupled with high population density, poverty, illiteracy and lack of infrastructure development, developing countries are more vulnerable to suffer from the damaging potential of such disasters. Though it is almost impossible to completely neutralise the damage due to these disasters, it is, however possible to (i) minimise the potential risks by developing disaster early warning strategies (ii) prepare developmental plans to provide resilience to such disasters, (iii) mobilize resources including communication and telemedicinal services and (iv) to help in rehabilitation and post-disaster reconstruction. Space borne platforms have demonstrated their capability in efficient disaster management. While communication satellites help in disaster warning, relief mobilisation and telemedicinal support, Earth observation satellites provide the basic support in pre-disaster preparedness programmes, in-disaster response and monitoring activities, and post-disaster reconstruction. The paper examines the information requirements for disaster risk management, assess developing country capabilities for building the necessary decision support systems, and evaluate the role of satellite remote sensing. It describes several examples of initiatives from developing countries in their attempt to evolve a suitable strategy for disaster preparedness and operational framework for the disaster management Using remote sensing data in conjunction with other collateral information. It concludes with suggestions and recommendations to establish a worldwide network of necessary space and ground segments towards strengthening the technological capabilities for disaster management and mitigation.

Only phase 1 will be discussed in this paper.

  6. Ownership, competition, and the adoption of new technologies and cost-saving practices in a fixed-price environment. (United States)

    Hirth, R A; Chernew, M E; Orzol, S M


    Advances in medical technology have been implicated as the primary cause of rising health care expenditures. It is not yet known whether the increasing prevalence of managed care mechanisms, particularly capitation, will change substantially incentives for acquiring and using cost-increasing innovations. We examined the decisions of dialysis units (a set of providers that has faced capitation and real decreases in payment for several decades) with respect to use of cost-increasing technologies that enhance quality of care, cost-cutting practices that reduce quality of care, and amenities desired by patients that are unrelated to quality of care. We found that the dialysis payment system does not appear to have blocked access to a number of new, quality-enhancing technologies that were developed in the 1980s. However, facilities made adjustments along other valuable margins to facilitate adoption of these technologies; use of new technologies varied with numerous facility, regulatory, and case-mix characteristics including ownership, chain membership, size, market competition, and certificate of need programs. Interestingly, the trade-offs made by for-profit and nonprofit facilities when faced with fixed prices appeared quite different. For-profits tended to deliver lower technical quality of care but more amenities, while nonprofits favored technical quality of care over amenities. Our findings may have implications for the response of other types of health care providers to capitation and increasing economic constraints.

  7. A cooperative power trading system based on satisfaction space technology

    International Nuclear Information System (INIS)

    Matsumoto, K.; Maruo, T.; Mori, N.


    This paper proposed a new power trading system model designed to ensure customer cooperation with power suppliers. Designed as an Internet application, the cooperative power trading system modelled power markets using a satisfaction space technology A network model of electric power trading systems was developed to create a communication network system that consisted of suppliers, customers, and auctioneers. When demand exceeded supply, the auctioneer in the trading system requested power reductions from customers. Rewards were paid to maintain the degree of satisfaction of the customers. The supplier's evaluation function was defined as a function of market price and power supply. A power reducing method was developed using a combinatorial optimization technique. Suppliers and customers submitted bids for initial power trading quantities, while the auctioneer decided a market price based on bidding values. After receiving the market price, suppliers and customers submitted a second set of bids for expected power trading quantities. A power reduction plan was then developed by the auctioneer to balance the amount of power supply and demand. The system can be applied to customers whose evaluation functions cannot be estimated beforehand, as the auctioneer was able to choose the most efficient power reduction point selected by consumers using a maximum steep slope method. Simulations conducted to validate the trading system demonstrated that the system is capable of choosing efficient energy reduction plans. 6 refs., 4 tabs., 3 figs

  10. Potential Opportunities for Investment in Space Technologies in Latin-America: a Case for Mexico (United States)

    Sanchez, G.


    Student, Master of Space Studies. International Space University. Strasbourg Central The objective of this paper is to analyze the possible commercial benefits that the global manufacturing space industry could obtain by investing in Latin-American countries. Spacecraft manufacturers have recently been complaining about small margins. They claim that customers demand technological advancement at the same time as they push for quick delivery and competitive prices. They also argue that operators (their main customers) do have great profits. Thus, manufacturers would like to raise the prices of their spacecraft (SpaceNews. January 7, 2002. P.17). This may sound logical, but it would be interesting to analyze if the industry could find alternative ways of saving money while remaining competitive. Mexico is a good example of a Latin-American country that has received foreign investment for establishing manufacturing and assembly plants for different industries. This has been mainly due to two special characteristics of the Mexican manufacturing workforce: low labor costs and qualified, reliable human resources. As a result, Mexican manufacturing industry has acquired a solid reputation worldwide. A similar story can be told about other industries such as electronics, computer assembly, clothes, etc. It is probably worth to make an analogy with a labor-demanding industry that already has experience in the Mexican market: the car industry has found a formula to keep manufacturing costs low while maintaining production and quality levels. Mexico currently manufactures and assembles cars for European, Japanese and American companies for the international market. If the same success story could be repeated for the spacecraft manufacturing industry, the benefits would be enormous. Manufacturers could consider relocating their plants to Mexico to manufacture and test parts or entire spacecraft. This would help reduce the cost of human labor, especially because of the long

  12. How carbon pricing changes the relative competitiveness of low-carbon baseload generating technologies

    Energy Technology Data Exchange (ETDEWEB)

    Nicholson, M.; Biegler, T.; Brook, B.W. [University of Adelaide, Adelaide, SA (Australia). School of Earth & Environmental Science


    There is wide public debate about which electricity generating technologies will best be suited to reduce greenhouse gas emissions (GHG). Sometimes this debate ignores real-world practicalities and leads to over-optimistic conclusions. Here we define and apply a set of fit-for-service criteria to identify technologies capable of supplying baseload electricity and reducing GHGs by amounts and within the timescale set by the Intergovernmental Panel on Climate Change (IPCC). Only five current technologies meet these criteria: coal (both pulverised fuel and integrated gasification combined cycle) with carbon capture and storage (CCS); combined cycle gas turbine with CCS; Generation III nuclear fission; and solar thermal backed by heat storage and gas turbines. To compare costs and performance, we undertook a meta-review of authoritative peer-reviewed studies of levelised cost of electricity (LCOE) and life-cycle GHG emissions for these technologies. Future baseload electricity technology selection will be influenced by the total cost of technology substitution, including carbon pricing, which is synergistically related to both LCOE and emissions. Nuclear energy is the cheapest option and best able to meet the IPCC timetable for GHG abatement. Solar thermal is the most expensive, while CCS will require rapid major advances in technology to meet that timetable.

  19. Impact of competitive electricity market on renewable generation technology choice and policies in the United States

    International Nuclear Information System (INIS)

    Sarkar, Ashok


    Market objectives based on private value judgments will conflict with social policy objectives toward environmental quality in an emerging restructured electricity industry. This might affect the choice of renewables in the future generation mix. The US electricity industry's long-term capacity planning and operations is simulated for alternative market paradigms to study this impact. The analysis indicates that the share of renewable energy generation sources would decrease and emissions would increase considerably in a more competitive industry, with greater impact occurring in a monopoly market. Alternative environmental policy options can overcome market failures and help achieve appropriate levels of renewable generation. An evaluation of these policies indicate their varying cost-effectiveness, with higher levels of intervention necessary if market power exists. (Author)

    Arvidson, R.; Foing, B. H.; Plescial, J.; Cohen, B.; Blamont, J. E.


    We report on the Beijing Lunar Declaration endorsed by the delegates of the Global Lunar Conference/11th ILEWG Conference on Exploration and Utilisation of the Moon, held at Beijing on 30 May- 3 June 2010. Specifically we focus on Part B:Technologies and resources; Infrastructures and human aspects; Moon, Space, Society and Young Explorers. We recommend continued and enhanced development and implementation of sessions about lunar exploration, manned and robotic, at key scientific and engineering meetings. A number of robotic missions to the Moon are now undertaken independently by various nations, with a degree of exchange of information and coordination. That should increase towards real cooperation, still allowing areas of competition for keeping the process active, cost-effective and faster. - Lunar landers, pressurized lunar rover projects as presented from Europe, Asia and America are important steps that can create opportunities for international collaboration, within a coordinated village of robotic precursors and assistants to crew missions. - We have to think about development, modernization of existing navigation capabilities, and provision of lunar positioning, navigation and data relay assets to support future robotic and human exploration. New concepts and new methods for transportation have attracted much attention and are of great potential.

  2. Competition and Synergy of Different Technologies in the Subsurface: A Case Study for CCS vs. Geothermal Energy Production (United States)

    Kissinger, Alexander; Juan-Lien Ramírez, Alina; Class, Holger


    Global climate change, shortage of resources and the resulting turn towards renewable sources of energy lead to a growing demand for the utilization of subsurface systems. Among these competing uses are Carbon Capture and Storage (CCS), geothermal energy, nuclear waste disposal, "renewable" methane or hydrogen storage as well as the ongoing production of fossil resources like oil, gas, and coal. The different uses of the subsurface can result in competition for the limited subsurface space, but in some cases there may also be synergetic effects, if the technologies are combined in a clever way. The idea behind this case study is to investigate the effects of a CCS site on a geothermal power plant operated in its vicinity and present both positive and negative impacts. During CCS operations large quantities of carbon dioxide (CO2) are injected into a storage formation. This causes a pressure increase as the brine in the formation is displaced by CO2. These elevations in pressure can have an extent of several tens of kilometers from the injection well in contrast to the much smaller extent of the CO2 plume. If geothermal power plants operate in the range influenced by pressure evaluation, this may have an impact on their performance. For example: Increased discharge of "warm" brine could be favorable for geothermal power plants as the time until thermal depletion of the reservoir may also increase Early breakthrough of the cold water front between an injection and an extraction well due to a brine discharge "pushing" the cold water front towards the extraction well may lead to a decrease in performance of the power plant Of course, there is a huge number of possible hydrogeological settings and technical configurations for geothermal power production that may be combined to an even larger number of possible scenarios. In this work however we use a simple model setup in which we incorporate and vary the parameters that we think are crucial. Only porous (not fractured

  8. Technological competition, increasing efficiency and lock-in in power generation of photovoltaic origin; Competition technologique, rendements croissants et lock-in dans la production d'electricite d'origine solaire photovoltaique

    Energy Technology Data Exchange (ETDEWEB)

    Taillant, P.


    In this study, the evolutionistic model of technological competition of B. Arthur is used to analyze the phenomena of increasing efficiency of adoption and the technological lock-in situation in the sector of photovoltaic cells for power generation. The processes of path dependence and random historical factors, like the public orders, can lead to a situation where the dominating technology is not necessary the most efficient. In the case of solar photovoltaic, the dominating 'crystalline silicon' technology is the one that has today the best energy efficiency. However, taking into account the evolution of its experience curve which shows a beginning of exhausting of the learning effects, the perspectives of cost reduction seem to be limited despite a sustained demand and intense R and D activities. On the other hand, the thin film technology, with lower efficiencies, would gain in competitiveness thanks to the automation of manufacturing processes. In these circumstances, the technological public policies have to maintain a diversity in the choice of possible technologies in order to allow the promising, but less attractive today, technologies to develop in the future.

  9. Emerging Geospatial Sharing Technologies in Earth and Space Science Informatics (United States)

    Singh, R.; Bermudez, L. E.


    Emerging Geospatial Sharing Technologies in Earth and Space Science Informatics The Open Geospatial Consortium (OGC) mission is to serve as a global forum for the collaboration of developers and users of spatial data products and services, and to advance the development of international standards for geospatial interoperability. The OGC coordinates with over 400 institutions in the development of geospatial standards. In the last years two main trends are making disruptions in geospatial applications: mobile and context sharing. People now have more and more mobile devices to support their work and personal life. Mobile devices are intermittently connected to the internet and have smaller computing capacity than a desktop computer. Based on this trend a new OGC file format standard called GeoPackage will enable greater geospatial data sharing on mobile devices. GeoPackage is perhaps best understood as the natural evolution of Shapefiles, which have been the predominant lightweight geodata sharing format for two decades. However the format is extremely limited. Four major shortcomings are that only vector points, lines, and polygons are supported; property names are constrained by the dBASE format; multiple files are required to encode a single data set; and multiple Shapefiles are required to encode multiple data sets. A more modern lingua franca for geospatial data is long overdue. GeoPackage fills this need with support for vector data, image tile matrices, and raster data. And it builds upon a database container - SQLite - that's self-contained, single-file, cross-platform, serverless, transactional, and open source. A GeoPackage, in essence, is a set of SQLite database tables whose content and layout is described in the candidate GeoPackage Implementation Specification available at The second trend is sharing client 'contexts'.

  11. Technology Estimating 2: A Process to Determine the Cost and Schedule of Space Technology Research and Development (United States)

    Cole, Stuart K.; Wallace, Jon; Schaffer, Mark; May, M. Scott; Greenberg, Marc W.


    As a leader in space technology research and development, NASA is continuing in the development of the Technology Estimating process, initiated in 2012, for estimating the cost and schedule of low maturity technology research and development, where the Technology Readiness Level is less than TRL 6. NASA' s Technology Roadmap areas consist of 14 technology areas. The focus of this continuing Technology Estimating effort included four Technology Areas (TA): TA3 Space Power and Energy Storage, TA4 Robotics, TA8 Instruments, and TA12 Materials, to confine the research to the most abundant data pool. This research report continues the development of technology estimating efforts completed during 2013-2014, and addresses the refinement of parameters selected and recommended for use in the estimating process, where the parameters developed are applicable to Cost Estimating Relationships (CERs) used in the parametric cost estimating analysis. This research addresses the architecture for administration of the Technology Cost and Scheduling Estimating tool, the parameters suggested for computer software adjunct to any technology area, and the identification of gaps in the Technology Estimating process.

    Brown, Katie E.; Cousins, Peter; Culligan, Matt; Jonathan Botkin; DeGraaff, David; Bunea, Gabriella; Rose, Douglas; Bourne, Ben; Koehler, Oliver


    Under DOE's Technology Pathway Partnership program, SunPower Corporation developed turn-key, high-efficiency residential and commercial systems that are cost effective. Key program objectives include a reduction in LCOE values to 9-12 cents/kWh and 13-18 cents/kWh respectively for the commercial and residential markets. Target LCOE values for the commercial ground, commercial roof, and residential markets are 10, 11, and 13 cents/kWh. For this effort, SunPower collaborated with a variety of suppliers and partners to complete the tasks below. Subcontractors included: Solaicx, SiGen, Ribbon Technology, Dow Corning, Xantrex, Tigo Energy, and Solar Bridge. SunPower's TPP addressed nearly the complete PV value chain: from ingot growth through system deployment. Throughout the award period of performance, SunPower has made progress toward achieving these reduced costs through the development of 20%+ efficient modules, increased cell efficiency through the understanding of loss mechanisms and improved manufacturing technologies, novel module development, automated design tools and techniques, and reduced system development and installation time. Based on an LCOE assessment using NREL's Solar Advisor Model, SunPower achieved the 2010 target range, as well as progress toward 2015 targets.

  19. Characterizing the Radiation Survivability of Space Solar Cell Technologies for Heliospheric Missions (United States)

    Lee, J. H.; Walker, D.; Mann, C. J.; Yue, Y.; Nocerino, J. C.; Smith, B. S.; Mulligan, T.


    Space solar cells are responsible for powering the majority of heliospheric space missions. This paper will discuss methods for characterizing space solar cell technologies for on-orbit operations that rely on a series of laboratory tests that include measuring the solar cells' beginning of life performance under simulated (e.g. AM0 or air mass zero) sunlight over different operating temperatures and observing their end of life performance following exposure to laboratory-generated charged particle radiation (protons and electrons). The Aerospace Corporation operates a proton implanter as well as electron gun facilities and collaborates with external radiation effects facilities to expose space solar cells or other space technologies to representative space radiation environments (i.e. heliosphere or magnetosphere of Earth or other planets), with goals of characterizing how the technologies perform over an anticipated space mission timeline and, through the application of precision diagnostic capabilities, understanding what part of the solar cell is impacted by varying space radiation environments. More recently, Aerospace has been hosting solar cell flight tests on its previously-flown CubeSat avionics bus, providing opportunities to compare the laboratory tests to on-orbit observations. We hope through discussion of the lessons learned and methods we use to characterize how solar cells perform after space radiation exposure that similar methodology could be adopted by others to improve the state of knowledge on the survivability of other space technologies required for future space missions.

    International Nuclear Information System (INIS)


    The Government of the United Republic of Tanzania recognizes that science, technology and innovation (STI) are vital to our economic and social progress. In an increasingly globalised world, it is recognised that high levels of investment in research and innovation are essential, both for economic competitiveness and to yield innovations in areas such as agriculture, health, natural resources, environment and energy sectors and make tangible improvements to the quality of our life. The government also realizes the need to provide an enabling environment for competition and innovation which in turn creates pressure for improvements in efficiency, quality and productivity. The development of a knowledge economy is a key challenge that is facing Tanzania today. It is essential that the country strives to build a truly knowledge based society. Such a society will offer new opportunities for economic and social advancement. It is therefore important that for a knowledge translation and disseminations are created and strengthened. The context to this is that knowledge is the currency for development.(author)

  2. Monolithic Microwave Integrated Circuit (MMIC) technology for space communications applications (United States)

    Connolly, Denis J.; Bhasin, Kul B.; Romanofsky, Robert R.


    Future communications satellites are likely to use gallium arsenide (GaAs) monolithic microwave integrated-circuit (MMIC) technology in most, if not all, communications payload subsystems. Multiple-scanning-beam antenna systems are expected to use GaAs MMIC's to increase functional capability, to reduce volume, weight, and cost, and to greatly improve system reliability. RF and IF matrix switch technology based on GaAs MMIC's is also being developed for these reasons. MMIC technology, including gigabit-rate GaAs digital integrated circuits, offers substantial advantages in power consumption and weight over silicon technologies for high-throughput, on-board baseband processor systems. For the more distant future pseudomorphic indium gallium arsenide (InGaAs) and other advanced III-V materials offer the possibility of MMIC subsystems well up into the millimeter wavelength region. All of these technology elements are in NASA's MMIC program. Their status is reviewed.

  6. An economic analysis of space solar power and its cost competitiveness as a supplemental source of energy for space and ground markets (United States)

    Marzwell, N. I.


    Economic Growth has been historically associated with nations that first made use of each new energy source. There is no doubt that Solar Power Satellites is high as a potential energy system for the future. A conceptual cost model of the economics value of space solar power (SSP) as a source of complementary power for in-space and ground applications will be discussed. Several financial analysis will be offered based on present and new technological innovations that may compete with or be complementary to present energy market suppliers depending on various institutional arrangements for government and the private sector in a Global Economy. Any of the systems based on fossil fuels such as coal, oil, natural gas, and synthetic fuels share the problem of being finite resources and are subject to ever-increasing cost as they grow ever more scarce with drastic increase in world population. Increasing world population and requirements from emerging underdeveloped countries will also increase overall demand. This paper would compare the future value of SSP with that of other terrestrial renewable energy in distinct geographic markets within the US, in developing countries, Europe, Asia, and Eastern Europe.

  17. Space power needs and forecasted technologies for the 1990s and beyond

    International Nuclear Information System (INIS)

    Buden, D.; Albert, T.


    A new generation of reactors for electric power will be available for space missions to satisfy military and civilian needs in the 1990s and beyond. To ensure a useful product, nuclear power plant development must be cognizant of other space power technologies. Major advances in solar and chemical technologies need to be considered in establishing the goals of future nuclear power plants. In addition, the mission needs are evolving into new regimes. Civilian and military power needs are forecasted to exceed anything used in space to date. Technology trend forecasts have been mapped as a function of time for solar, nuclear, chemical, and storage systems to illustrate areas where each technology provides minimum mass. Other system characteristics may dominate the usefulness of a technology on a given mission. This paper will discuss some of these factors, as well as forecast future military and civilian power needs and the status of technologies for the 1990s and 2000s. 6 references

The results of the assessment are summarized in the report. Overall, thermoacoustic and magnetic technologies were judged to have the best prospects for competing with vapor compression technology, with thermotunneling, thermoelectric, and thermionic technologies trailing behind in that order.

  20. Large space system: Charged particle environment interaction technology (United States)

    Stevens, N. J.; Roche, J. C.; Grier, N. T.


    Large, high voltage space power systems are proposed for future space missions. These systems must operate in the charged-particle environment of space and interactions between this environment and the high voltage surfaces are possible. Ground simulation testing indicated that dielectric surfaces that usually surround biased conductors can influence these interactions. For positive voltages greater than 100 volts, it has been found that the dielectrics contribute to the current collection area. For negative voltages greater than-500 volts, the data indicates that the dielectrics contribute to discharges. A large, high-voltage power system operating in geosynchronous orbit was analyzed. Results of this analysis indicate that very strong electric fields exist in these power systems.

  1. Solar and Space Physics: A Science for a Technological Society (United States)


    From the interior of the Sun, to the upper atmosphere and near-space environment of Earth, and outward to a region far beyond Pluto where the Sun's influence wanes, advances during the past decade in space physics and solar physics the disciplines NASA refers to as heliophysics have yielded spectacular insights into the phenomena that affect our home in space. This report, from the National Research Council's (NRC's) Committee for a Decadal Strategy in Solar and Space Physics, is the second NRC decadal survey in heliophysics. Building on the research accomplishments realized over the past decade, the report presents a program of basic and applied research for the period 2013-2022 that will improve scientific understanding of the mechanisms that drive the Sun's activity and the fundamental physical processes underlying near-Earth plasma dynamics, determine the physical interactions of Earth's atmospheric layers in the context of the connected Sun-Earth system, and enhance greatly the capability to provide realistic and specific forecasts of Earth's space environment that will better serve the needs of society. Although the recommended program is directed primarily to NASA (Science Mission Directorate -- Heliophysics Division) and the National Science Foundation (NSF) (Directorate for Geosciences -- Atmospheric and Geospace Sciences) for action, the report also recommends actions by other federal agencies, especially the National Oceanic and Atmospheric Administration (NOAA) those parts of NOAA charged with the day-to-day (operational) forecast of space weather. In addition to the recommendations included in this summary, related recommendations are presented in the main text of the report.

    Eldridge, John M.; Leemaster, Jacob Edward; Van Leeuwen, Brian P.


    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.

  4. The role of National Strategies in maintaining Competitive Edge in Information and Communication Technologies

    Directory of Open Access Journals (Sweden)

    Ciprian Popoviciu


    Full Text Available This paper examines the economical impact of IPv6, Internet Protocol's next generation. Technically, IPv6 represents an upgrade, an evolution that offers the resources necessary for deeper and wider market penetration of the IP technology, to support the needs of a global economy, to build new products and new services. Politically and economically it has the potential of being a quiet revolution. Countries that trailed US into the information revolution recognize this opportunity to take a leading role in its next expansion phase and have developed national strategies to help better position their respective economies. Despite understanding the constraints imposed by the current version of IP, the private sector is currently inclined to largely ignore IPv6 because of its initial deployment costs and long term returns. Forced by high investor expectations to focus exclusively on the immediate bottom line it trades long term growth opportunities for short term benefits revolving around productivity increases. The paper analyses the importance of a National Strategy in driving IPv6 adoption and in closing a widening knowledge and deployment gap between US and countries such as China, Japan, Korea and the EU.

    Advanced planning within NASA has identified several bold space exploration initiatives. The successful implementation of these missions will require a supporting space infrastructure which would include a fuel depot, an orbiting facility to store, transfer and process large quantities of cryogenic fluids. In order to adequately plan the technology development programs required to enable the construction and operation of a fuel depot, a multidisciplinary workshop was convened to assess critical technologies and their state of maturity. Since technology requirements depend strongly on the depot design assumptions, several depot concepts are presented with their effect of criticality ratings. Over 70 depot-related technology areas are addressed.

  8. Laser ablation and competitive technologies in paint stripping of heavy anticorrosion coatings (United States)

    Schuöcker, Georg D.; Bielak, Robert


    During the last years surface preparation prior to coating operations became an important research and development task, since tightened environmental regulations have to be faced in view of the deliberation of hazardous compounds of coatings. Especially, ship-yards get more and more under pressure, because the environmental commitment of their Asian competitors is fairly limited. Therefore, in the US and in Europe several technology evaluation projects have been launched to face this challenge. The majority of coating service providers and ship yards use grit blasting; this process causes heavy emissions as of dust and enormous amounts of waste as polluted sand. Coating removal without any blasting material would reduce the environmental impact. Laser processing offers ecological advantages. Therefore thermal processes like laser ablation have been studied thoroughly in several published projects and also in this study. Many of these studies have been focused on the maintenance of airplanes, but not on de-coating of heavy protective coatings. In this case the required laser power is extra-high. This study is focused on the maintenance of heavy anti-corrosion coatings and compares the industrial requirements and the opportunities of the innovative laser processes. Based on the results of this analysis similar approaches as e.g. plasma jet coating ablation have been studied. It was concluded that none of these methods can compete economically with the conventional processes as grit blasting and water jetting since the required ablation rate is very high (>60m2/h). A new process is required that is not based on any blasting operation and which does not depend strongly on the coating's characteristic. The delamination of the coating where the coatings is not removed by evaporation, but in little pieces of the complete coating system meets these requirements. The delamination can be accomplished by the thermal destruction of the primer coating by an intense heat pulse

  10. Radioisotope Power: A Key Technology for Deep Space Explorations (United States)

    Schmidt, George R.; Sutliff, Thomas J.; Duddzinski, Leonard


    A Radioisotope Power System (RPS) generates power by converting the heat released from the nuclear decay of radioactive isotopes, such as Plutonium-238 (Pu-238), into electricity. First used in space by the U.S. in 1961, these devices have enabled some of the most challenging and exciting space missions in history, including the Pioneer and Voyager probes to the outer solar system; the Apollo lunar surface experiments; the Viking landers; the Ulysses polar orbital mission about the Sun; the Galileo mission to Jupiter; the Cassini mission orbiting Saturn; and the recently launched New Horizons mission to Pluto. Radioisotopes have also served as a versatile heat source for moderating equipment thermal environments on these and many other missions, including the Mars exploration rovers, Spirit and Opportunity. The key advantage of RPS is its ability to operate continuously, independent of orientation and distance relative to the Sun. Radioisotope systems are long-lived, rugged, compact, highly reliable, and relatively insensitive to radiation and other environmental effects. As such, they are ideally suited for missions involving long-lived, autonomous operations in the extreme conditions of space and other planetary bodies. This paper reviews the history of RPS for the U.S. space program. It also describes current development of a new Stirling cycle-based generator that will greatly expand the application of nuclear-powered missions in the future.

  11. Progress in space nuclear reactor power systems technology development - The SP-100 program (United States)

    Davis, H. S.


    Activities related to the development of high-temperature compact nuclear reactors for space applications had reached a comparatively high level in the U.S. during the mid-1950s and 1960s, although only one U.S. nuclear reactor-powered spacecraft was actually launched. After 1973, very little effort was devoted to space nuclear reactor and propulsion systems. In February 1983, significant activities toward the development of the technology for space nuclear reactor power systems were resumed with the SP-100 Program. Specific SP-100 Program objectives are partly related to the determination of the potential performance limits for space nuclear power systems in 100-kWe and 1- to 100-MW electrical classes. Attention is given to potential missions and applications, regimes of possible space power applicability, safety considerations, conceptual system designs, the establishment of technical feasibility, nuclear technology, materials technology, and prospects for the future.

    During the spring and summer months of 1987, the Aero Propulsion Laboratory of the Air Force Wright Aeronautical Laboratories, Wright-Patterson AFB, Ohio in cooperation with the Air Force Space Technology Center at Kirtland AFB, New Mexico, undertook an initiative to develop a Strategic Plan for Space Power Technology Development. The initiative was called SPT21, Space Power Technology for the Twenty-First Century. The planning process involved the participation of other Government organizations (U.S. Army, Navy, DOE and NASA) along with major aerospace companies and universities. Following an SPT21 kickoff meeting on 28 May 1987, detailed strategic planning was accomplished through seven (7) Space Power Technology Discipline Workshops commencing in June 1987 and concluding in August 1987. Technology Discipline Workshops were conducted in the following areas: (1) Solar Thermal Dynamic Power Systems (2) Solar Photovoltaic Cells and Arrays (3) Thermal Management Technology (4) Energy Storage Technology (5) Nuclear Power Systems Technology (6) Power Conditioning, Distribution and Control and (7) Systems Technology/Advanced Concepts. This technical paper summarizes the planning process and describes the salient findings and conclusions of the workshops

    Diekmann, Andreas; Richarz, Hans.-Peter

    The paper describes the interrelation of space activities and global socio-economic trends like "globalisation of markets" and "renaissance of fine arts". The interrelation reveals the economic strategic, technological and scientific dimension of space activities and their benefits to mankind. Then, the significance and perspectives of space activities in these dimensions are examined in more detail. The paper calls (1) for a more visible initiative to employ space activities to tackle urgent questions of global change and development, and (2) for a stronger impetus to secure European economic position in space sector as a key industry of the 21st century.

  17. Contagious architecture: computation, aesthetics, and space (technologies of lived abstraction)

    CERN Document Server

    Parisi, Luciana


    In Contagious Architecture, Luciana Parisi offers a philosophical inquiry into the status of the algorithm in architectural and interaction design. Her thesis is that algorithmic computation is not simply an abstract mathematical tool but constitutes a mode of thought in its own right, in that its operation extends into forms of abstraction that lie beyond direct human cognition and control. These include modes of infinity, contingency, and indeterminacy, as well as incomputable quantities underlying the iterative process of algorithmic processing. The main philosophical source for the project is Alfred North Whitehead, whose process philosophy is specifically designed to provide a vocabulary for "modes of thought" exhibiting various degrees of autonomy from human agency even as they are mobilized by it. Because algorithmic processing lies at the heart of the design practices now reshaping our world -- from the physical spaces of our built environment to the networked spaces of digital culture -- the nature o...

  18. Space Solar Power Technology Demonstration for Lunar Polar Applications: Laser-Photovoltaic Wireless Power Transmission (United States)

    Henley, M. W.; Fikes, J. C.; Howell, J.; Mankins, J. C.; Howell, Joe T. (Technical Monitor)


    Space Solar Power technology offers unique benefits for near-term NASA space science missions, which can mature this technology for other future applications. "Laser-Photo-Voltaic Wireless Power Transmission" (Laser-PV WPT) is a technology that uses a laser to beam power to a photovoltaic receiver, which converts the laser's light into electricity. Future Laser-PV WPT systems may beam power from Earth to satellites or large Space Solar Power satellites may beam power to Earth, perhaps supplementing terrestrial solar photo-voltaic receivers. In a near-term scientific mission to the moon, Laser-PV WPT can enable robotic operations in permanently shadowed lunar polar craters, which may contain ice. Ground-based technology demonstrations are proceeding, to mature the technology for this initial application, in the moon's polar regions.

  19. Making Breakthroughs in the Turbulent Decade: China's Space Technology During the Cultural Revolution. (United States)

    Li, Chengzhi; Zhang, Dehui; Hu, Danian


    This article discusses why Chinese space programs were able to develop to the extent they did during the turbulent decade of the Cultural Revolution (1966-1976). It first introduces briefly what China had accomplished in rocket and missile technology before the Cultural Revolution, including the establishment of a system for research and manufacturing, breakthroughs in rocket technology, and programs for future development. It then analyzes the harmful impacts of the Cultural Revolution on Chinese space programs by examining activities of contemporary mass factions in the Seventh Ministry of Machinery Industry. In the third section, this article presents the important developments of Chinese space programs during the Cultural Revolution and explores briefly the significance of these developments for the future and overall progress in space technology. Finally, it discusses the reasons for the series of developments of Chinese space technology during the Cultural Revolution. This article concludes that, although the Cultural Revolution generated certain harmful impacts on the development of Chinese space technology, the Chinese essentially accomplished their scheduled objectives in their space program, both because of the great support of top Chinese leaders, including the officially disgraced Lin Biao and the Gang of Four, and due to the implementation of many effective special measures.

    Jansen, Frank, E-mail: [DLR Institute of Space Systems, Robert-Hooke-Str. 7, 28359 Bremen (Germany); Behrens, Joerg [DLR Institute of Space Systems, Robert-Hooke-Str. 7, 28359 Bremen (Germany); Pospisil, Stanislav [Czech Technical University, IEAP, 12800 Prague 2, Horska 3a/22 (Czech Republic); Kudela, Karel [Slovak Academy of Sciences, IEP, 04001 Kosice, Watsonova 47 (Slovakia)


    We review the current status from the scientific and technological point of view of solar energetic particles, solar and galactic cosmic ray measurements as well as high energy UV-, X- and gamma-ray imaging of the Sun. These particles and electromagnetic data are an important tool for space situational awareness (SSA) aspects like space weather storm predictions to avoid failures in space, air and ground based technological systems. Real time data acquisition, position and energy sensitive imaging are demanded by the international space weather forecast services. We present how newly developed, highly miniaturized radiation detectors can find application in space in view of future SSA related satellites as a novel space application due to their counting and imaging capabilities.

  11. Synthetic Biology as an Enabling Technology for Space Exploration (United States)

    Rothschild, Lynn J.


    Human exploration off planet is severely limited by the cost of launching materials into space and by re-supply. Thus materials brought from Earth must be light, stable and reliable at destination. Using traditional approaches, a lunar or Mars base would require either transporting a hefty store of metals or heavy manufacturing equipment and construction materials for in situ extraction; both would severely limit any other mission objectives. Long-term human space presence requires periodic replenishment, adding a massive cost overhead. Even robotic missions often sacrifice science goals for heavy radiation and thermal protection. Biology has the potential to solve these problems because life can replicate and repair itself, and perform a wide variety of chemical reactions including making food, fuel and materials. Synthetic biology enhances and expands life's evolved repertoire. Using organisms as feedstock, additive manufacturing through bioprinting will make possible the dream of producing bespoke tools, food, smart fabrics and even replacement organs on demand. This new approach and the resulting novel products will enable human exploration and settlement on Mars, while providing new manufacturing approaches for life on Earth.

  12. Status of Mirror Technology for the Next Generation Space Telescope (United States)

    Jacobson, D. N.


    The NGST primary mirror is anticipated to be a segmented deployable optic with segment size being in the range of 1-3m depending on the details of the architecture. Over the past 4 years the NGST program has initiated and implemented an aggressive lightweight cryogenic mirror technology program. The program was designed to challenge and excite the optical community in reaching a new standard in production of lightweight optics. The goal was to develop optics at segment, it was felt that a 1.2-2.0m optic would be of sufficient size to understand the mirror material and fabrication processes which drive the cost and schedule of mirror production. The ultimate goals of the technology program are both to demonstrate mirrors meeting the NGST performance requirements, and to establish cost and schedule credibility for producing and implementing the mirrors for the NGST flight system. Establishing cost and schedule credibility is essential to NGST which is a cost capped mission, with past program experience demonstrating that the optics will be a large portion of the total cost of the program. The first two years of the program were dedicated to understanding the various applicable materials, funding those materials to various levels of maturity and implementing the first large mirror procurement, the NGST Mirror System Demonstrator (NMSD), in order to establish a benchmark for the state-of-the-art in lightweight optics and to establish credibility that the goals of NGST could be achieved. The past two years of the program has seen major steps in the development of several mirror materials, which not only might have NGST applicability but could also support other programs for other customers. Additionally, a second large mirror procurement, the Advanced Mirror System Demonstrator (AMSD), has been implemented providing a focal point to complete the mirror technology development and lead ultimately to the production of mirrors that will fly on NEXUS (NGST flight

  14. A Study of Thermal Performance of Contemporary Technology-Rich Educational Spaces

    Directory of Open Access Journals (Sweden)

    Sarah Elmasry


    Full Text Available One of the most dominant features of a classroom space is its high occupancy, which results in high internal heat gain (approximately 5 KW. Furthermore, installation of educational technologies, such as smart boards, projectors and computers in the spaces increases potential internal heat gain. Previous studies on office buildings indicate that with the introduction of IT equipment in spaces during the last decade, cooling load demands are increasing with an associated increase in summer electrical demand. Due to the fact that educational technologies in specific correspond to pedagogical practices within the space, a lot of variations due to occupancy patterns occur. Also, thermal loads caused by educational technologies are expected to be dependent on spatial configuration, for example, position with respect to the external walls, lighting equipment, mobility of devices. This study explores the thermal impact of educational technologies in 2 typical educational spaces in a facility of higher education; the classroom and the computer lab. The results indicate that a heat gain ranging between 0.06 and 0.095 KWh/m2 is generated in the rooms when educational technologies are in use. The second phase of this study is ongoing, and investigates thermal zones within the rooms due to distribution of educational technologies. Through simulation of thermal performance of the rooms, alternative room configurations are thus recommended in response to the observed thermal zones.

  16. Miniaturization of components and systems for space using MEMS-technology (United States)

    Grönland, Tor-Arne; Rangsten, Pelle; Nese, Martin; Lang, Martin


    Development of MEMS-based (micro electro mechanical system) components and subsystems for space applications has been pursued by various research groups and organizations around the world for at least two decades. The main driver for developing MEMS-based components for space is the miniaturization that can be achieved. Miniaturization can not only save orders of magnitude in mass and volume of individual components, but it can also allow increased redundancy, and enable novel spacecraft designs and mission scenarios. However, the commercial breakthrough of MEMS has not occurred within the space business as it has within other branches such as the IT/telecom or automotive industries, or as it has in biotech or life science applications. A main explanation to this is the highly conservative attitude to new technology within the space community. This conservatism is in many senses motivated by a very low risk acceptance in the few and costly space projects that actually ends with a space flight. To overcome this threshold there is a strong need for flight opportunities where reasonable risks can be accepted. Currently there are a few flight opportunities allowing extensive use of new technology in space, but one of the exceptions is the PRISMA program. PRISMA is an international (Sweden, Germany, France, Denmark, Norway, Greece) technology demonstration program with focus on rendezvous and formation flying. It is a two satellite LEO mission with a launch scheduled for the first half of 2009. On PRISMA, a number of novel technologies e.g. RF metrology sensor for Darwin, autonomous formation flying based on GPS and vision-based sensors, ADN-based "green propulsion" will be demonstrated in space for the first time. One of the satellites will also have a miniaturized propulsion system onboard based on MEMS-technology. This novel propulsion system includes two microthruster modules, each including four thrusters with micro- to milli-Newton thrust capability. The novelty

  17. Technology Challenges and Opportunities for Very Large In-Space Structural Systems (United States)

    Belvin, W. Keith; Dorsey, John T.; Watson, Judith J.


    Space solar power satellites and other large space systems will require creative and innovative concepts in order to achieve economically viable designs. The mass and volume constraints of current and planned launch vehicles necessitate highly efficient structural systems be developed. In addition, modularity and in-space deployment/construction will be enabling design attributes. While current space systems allocate nearly 20 percent of the mass to the primary structure, the very large space systems of the future must overcome subsystem mass allocations by achieving a level of functional integration not yet realized. A proposed building block approach with two phases is presented to achieve near-term solar power satellite risk reduction with accompanying long-term technology advances. This paper reviews the current challenges of launching and building very large space systems from a structures and materials perspective utilizing recent experience. Promising technology advances anticipated in the coming decades in modularity, material systems, structural concepts, and in-space operations are presented. It is shown that, together, the current challenges and future advances in very large in-space structural systems may provide the technology pull/push necessary to make solar power satellite systems more technically and economically feasible.

  18. Integrating Space Communication Network Capabilities via Web Portal Technologies (United States)

    Johnston, Mark D.; Lee, Carlyn-Ann; Lau, Chi-Wung; Cheung, Kar-Ming; Levesque, Michael; Carruth, Butch; Coffman, Adam; Wallace, Mike


    We have developed a service portal prototype as part of an investigation into the feasibility of using Java portlet technology as a means of providing integrated access to NASA communications network services. Portal servers provide an attractive platform for this role due to the various built-in collaboration applications they can provide, combined with the possibility to develop custom inter-operating portlets to extent their functionality while preserving common presentation and behavior. This paper describes various options for integration of network services related to planning and scheduling, and results based on use of a popular open-source portal framework. Plans are underway to develop an operational SCaN Service Portal, building on the experiences reported here.

    In order for the shuttle tug or interim upper stage (IUS) to capture all the missions in the current mission model for the tug and the IUS, an auxiliary or kick stage, using a solid propellant rocket motor, is required. Two solid propellant rocket motor technology concepts are described. One concept, called the 'advanced propulsion module' motor, is an 1800-kg, high-mass-fraction motor, which is single-burn and contains Class 2 propellent. The other concept, called the high energy upper stage restartable solid, is a two-burn (stop-restartable on command) motor which at present contains 1400 kg of Class 7 propellant. The details and status of the motor design and component and motor test results to date are presented, along with the schedule for future work.

  20. The NASA In-Space Propulsion Technology Project's Current Products and Future Directions (United States)

    Anderson, David J.; Dankanich, John; Munk, Michelle M.; Pencil, Eric; Liou, Larry


    Since its inception in 2001, the objective of the In-Space Propulsion Technology (ISPT) project has been developing and delivering in-space propulsion technologies that enable or enhance NASA robotic science missions. These in-space propulsion technologies are applicable, and potentially enabling for future NASA flagship and sample return missions currently under consideration, as well as having broad applicability to future Discovery and New Frontiers mission solicitations. This paper provides status of the technology development, applicability, and availability of in-space propulsion technologies that recently completed, or will be completing within the next year, their technology development and are ready for infusion into missions. The paper also describes the ISPT project s future focus on propulsion for sample return missions. The ISPT technologies completing their development are: 1) the high-temperature Advanced Material Bipropellant Rocket (AMBR) engine providing higher performance for lower cost; 2) NASA s Evolutionary Xenon Thruster (NEXT) ion propulsion system, a 0.6-7 kW throttle-able gridded ion system; and 3) aerocapture technologies which include thermal protection system (TPS) materials and structures, guidance, navigation, and control (GN&C) models of blunt-body rigid aeroshells; and atmospheric and aerothermal effect models. The future technology development areas for ISPT are: 1) Planetary Ascent Vehicles (PAV); 2) multi-mission technologies for Earth Entry Vehicles (MMEEV) needed for sample return missions from many different destinations; 3) propulsion for Earth Return Vehicles (ERV) and transfer stages, and electric propulsion for sample return and low cost missions; 4) advanced propulsion technologies for sample return; and 5) Systems/Mission Analysis focused on sample return propulsion.

  1. Applying Space Technology to Enhance Control of an Artificial Arm (United States)

    Atkins, Diane; Donovan, William H.; Novy, Mara; Abramczyk, Robert


    At the present time, myoelectric prostheses perform only one function of the hand: open and close with the thumb, index and middle finger coming together to grasp various shaped objects. To better understand the limitations of the current single-function prostheses and the needs of the individuals who use them, The Institute for Rehabilitation and Research (TIRR), sponsored by the National Institutes of Health (August 1992 - November 1994), surveyed approximately 2500 individuals with upper limb loss. When asked to identify specific features of their current electric prosthesis that needed improvement, the survey respondents overwhelmingly identified the lack of wrist and finger movement as well as poor control capability. Simply building a mechanism with individual finger and wrist motion is not enough. Individuals with upper limb loss tend to reject prostheses that require continuous visual monitoring and concentration to control. Robotics researchers at NASA's Johnson Space Center (JSC) and Rice University have made substantial progress in myoelectric teleoperation. A myoelectric teleoperation system translates signals generated by an able-bodied robot operator's muscles during hand motions into commands that drive a robot's hand through identical motions. Farry's early work in myoelectric teleoperation used variations over time in the myoelectric spectrum as inputs to neural networks to discriminate grasp types and thumb motions. The resulting schemes yielded up to 93% correct classification on thumb motions. More recently, Fernandez achieved 100% correct non-realtime classification of thumb abduction, extension, and flexion on the same myoelectric data. Fernandez used genetic programming to develop functions that discriminate between thumb motions using myoelectric signal parameters. Genetic programming (GP) is an evolutionary programming method where the computer can modify the discriminating functions' form to improve its performance, not just adjust

  2. Large space system - Charged particle environment interaction technology. [effects on high voltage solar array performance (United States)

    Stevens, N. J.; Roche, J. C.; Grier, N. T.


    Large high-voltage space power systems proposed for future applications in both low earth orbit and geosynchronous altitudes must operate in the space charged-particle environment with possible interactions between this environment and the high-voltage surfaces. The paper reviews the ground experimental work to provide indicators for the interactions that could exist in the space power system. A preliminary analytical model of a large space power system is constructed using the existing NASA Charging Analyzer Program, and its performance in geosynchronous orbit is evaluated. The analytical results are used to illustrate the regions where detrimental interactions could exist and to establish areas where future technology is required.

  3. Space Technology: Game Changing Development Deep Space Engine (DSE) 100 lbf and 5 lbf Thruster Development and Qualification (United States)

    Barnett, Gregory


    Science mission studies require spacecraft propulsion systems that are high-performance, lightweight, and compact. Highly matured technology and low-cost, short development time of the propulsion system are also very desirable. The Deep Space Engine (DSE) 100-lbf thruster is being developed to meet these needs. The overall goal of this game changing technology project is to qualify the DSE thrusters along with 5-lbf attitude control thrusters for space flight and for inclusion in science and exploration missions. The aim is to perform qualification tests representative of mission duty cycles. Most exploration missions are constrained by mass, power and cost. As major propulsion components, thrusters are identified as high-risk, long-lead development items. NASA spacecraft primarily rely on 1960s' heritage in-space thruster designs and opportunities exist for reducing size, weight, power, and cost through the utilization of modern materials and advanced manufacturing techniques. Advancements in MON-25/MMH hypergolic bipropellant thrusters represent a promising avenue for addressing these deficiencies with tremendous mission enhancing benefits. DSE is much lighter and costs less than currently available thrusters in comparable thrust classes. Because MON-25 propellants operate at lower temperatures, less power is needed for propellant conditioning for in-space propulsion applications, especially long duration and/or deep-space missions. Reduced power results in reduced mass for batteries and solar panels. DSE is capable of operating at a wide propellant temperature range (between -22 F and 122 F) while a similar existing thruster operates between 45 F and 70 F. Such a capability offers robust propulsion operation as well as flexibility in design. NASA's Marshall Space Flight Center evaluated available operational Missile Defense Agency heritage thrusters suitable for the science and lunar lander propulsion systems.

  4. Effectiveness of cooperative learning compared to competitive or individual situations and its application to technology: a systematic review

    Directory of Open Access Journals (Sweden)



    Full Text Available This paper focuses on reviewing significant evidence about cooperative learning in comparison to competitive and individual situations. To do this, we identified the factors that improve or limit its application together with the impact of technology on this methodology. This evidence was the result of 18 meta-analyses made between 1980 and 2010. Meta-analysis is defined as the statistical analysis of a large collection of results that concern a research issue and come from individual studies with the idea of integrating their conclusions. The English and Spanish descriptors used were aprendizaje cooperativo, aprendizaje colaborativo, cooperative learning, collaborative learning and other terms related to meta-analysis such as evidencias significativas, mejores evidencias, integración de resultados, revisión sistemática, síntesis cuantitativa, meta-analysis, bestevidence, integrating findings, systematic integration, systematic review, synthesis. The search was not referred to any particular period of time. The resources and databases reviewed were extracted from the Web of Knowledge, Google Scholar, and the list of references given in the meta-analysis. The results show that cooperative learning, as a methodology, is more appropriate than other traditional methodologies. Its application in the new higher education context, as a result of the European Higher Education Area, can open the way for the inclusion of active and innovative teaching methodologies. So, the challenge for the faculty consists on integrating research, innovation and evaluation in their teaching in order to improve educational quality levels. In short, cooperative learning becomes a valuable indicator and a suitable tool to forecast positive results.

    For decades, researchers have studied the damage to DNA by high-energy radiation. Radiation induced damage include DNA strand breaks, base damage and base substitution. Currently, though, scientists are discovering that it is, in fact, the non-irradiated cells adjacent to the irradiated cells are the primary source of carcinogenesis. To address these ``bystander effects'', we developed a radiation detector using multi-clad scintillating fibers and silicon pixel arrays to study the effect of radiation on gene expression changes using Microelectromechanical systems (MEMS) technology. The efficiency of proton energy deposition on each of the different layers of the radiation tracking detector has been simulated using GEANT4 toolkit and tested experimentally using the detector. The position of the proton beam was determined from the intensity of the output signal from orthogonal planes of the tracking detector. We have developed and tested an instrument that automates the extraction and quantification of RNA from living cells that automates the collection, purification, and reverse transcription (RT) of RNA from a precisely-defined area of the biological sample.

  6. Use of Space Technology in Flood Mitigation (Western Province, Zambia) (United States)

    Mulando, A.


    Disasters, by definition are events that appear suddenly and with little warning. They are usually short lived, with extreme events bringing death, injury and destruction of buildings and communications. Their aftermath can be as damaging as their physical effects through destruction of sanitation and water supplies, destruction of housing and breakdown of transport for food, temporary shelter and emergency services. Since floods are one of the natural disasters which endanger both life and property, it becomes vital to know its extents and where the hazards exists. Flood disasters manifest natural processes on a larger scale and information provided by Remote Sensing is a most appropriate input to analysis of actual events and investigations of potential risks. An analytical and qualitative image processing and interpretation of Remotely Sensed data as well as other data such as rainfall, population, settlements not to mention but a few should be used to derive good mitigation strategies. Since mitigation is the cornerstone of emergency management, it therefore becomes a sustained action that will reduce or eliminate long term risks to people and property from natural hazards such as floods and their effects. This will definitely involve keeping of homes and other sensitive structures away from flood plains. Promotion of sound land use planning based on this known hazard, "FLOODS" is one such form of mitigation that can be applied in flood affected areas within flood plain. Therefore future mitigation technologies and procedures should increasingly be based on the use of flood extent information provided by Remote Sensing Satellites like the NOAA AVHRR as well as information on the designated flood hazard and risk areas.

  7. Technology Required to Image and Characterize an exo-Earth from Space (United States)

    Crill, Brendan


    NASA's Exoplanet Exploration Program (ExEP) guides the development of technology that enables the direct imaging and characterization of exo-Earths in the habitable zone of Sun-like stars with future space observatories. Here we present the 2018 ExEP Technology Gap List, an annual update to ExEP's list of technologies, to be advanced in the next 1-5 years. Key technology gaps are starlight suppression with a coronagraph (internal occulters) or a starshade (external occulters), enabling imaging at extreme contrast (more than 10 billion) by blocking on-axis starlight, while allowing the reflected light of off-axis exoplanets be detected. Building and operating a space coronagraph capable of imaging an exo-Earth will require new technologies beyond those of WFIRST, the first high-contrast coronagraph in space. A starshade has never been used in a space mission and requires new capabilities in precision deployment of large structures, starlight suppression, and in formation sensing and control. We review the current state-of-the-art in coronagraph and starshade technology and the performance level that must be achieved to discover and characterize Earth analogs.

    Perry, Jay L.; Abney, Morgan B.; Knox, James C.; Parrish, Keith J.; Roman, Monserrate C.; Jan, Darrell L.


    Exploring the frontiers of deep space continues to be defined by the technological challenges presented by safely transporting a crew to and from destinations of scientific interest. Living and working on that frontier requires highly reliable and efficient life support systems that employ robust, proven process technologies. The International Space Station (ISS), including its environmental control and life support (ECLS) system, is the platform from which humanity's deep space exploration missions begin. The ISS ECLS system Atmosphere Revitalization (AR) subsystem and environmental monitoring (EM) technical architecture aboard the ISS is evaluated as the starting basis for a developmental effort being conducted by the National Aeronautics and Space Administration (NASA) via the Advanced Exploration Systems (AES) Atmosphere Resource Recovery and Environmental Monitoring (ARREM) Project.. An evolutionary approach is employed by the ARREM project to address the strengths and weaknesses of the ISS AR subsystem and EM equipment, core technologies, and operational approaches to reduce developmental risk, improve functional reliability, and lower lifecycle costs of an ISS-derived subsystem architecture suitable for use for crewed deep space exploration missions. The most promising technical approaches to an ISS-derived subsystem design architecture that incorporates promising core process technology upgrades will be matured through a series of integrated tests and architectural trade studies encompassing expected exploration mission requirements and constraints.

  16. Portable Diagnostics Technology Assessment for Space Missions. Part 2; Market Survey (United States)

    Nelson, Emily S.; Chait, Arnon


    A mission to Mars of several years duration requires more demanding standards for all onboard instruments than a 6-month mission to the Moon or the International Space Station. In Part 1, we evaluated generic technologies and suitability to NASA needs. This prior work considered crew safety, device maturity and flightworthiness, resource consumption, and medical value. In Part 2, we continue the study by assessing the current marketplace for reliable Point-of-Care diagnostics. The ultimate goal of this project is to provide a set of objective analytical tools to suggest efficient strategies for reaching specific medical targets for any given space mission as program needs, technological development, and scientific understanding evolve.

  20. Infrared and submillimeter space missions in the coming decade programmes, programmatics, and technology

    CERN Document Server

    Sauvage, Marc; Gallais, Pascal; Vigroux, Laurent


    A revolution similar to that brought by CCDs to visible astronomy is still ahead in IR and submillimeter astronomy. There is certainly no wavelength range which has, over the past several years, seen such impressive advances in technology: large-scale detector arrays, new designs for cooling in space, lightweight mirror technologies. Scientific cases for observing the cold universe are outstanding. Observations in the FIR/Submm range will provide answers to such fundamental questions as: What is the spectrum of the primordial fluctuations? How do primeval galaxies look? What are the first stages of star formation? Most of the international space missions that have been triggered by these questions are presented in detail here. Technological issues raised by these missions are reviewed, as are the most recent achievements in cooling and detector technologies.
