Stritar, A.; Mavko, B.

The Krsko nuclear power plant in Slovenia was probably the first in the world that found itself in the middle of a war region. A number of preventive measures performed during and immediately after the war in summer 1991 by the plant personnel as well as some of related activities of the Reactor Engineering Division of the 'Jozef Stefan' Institute are described. All efforts were aimed at the minimization of the possible public radiological consequences during a military attack. The critical safety functions in such conditions were checked. Concern was further devoted to maintenance of the core cooling in the core and to integrity of the spent fuel pit. The cold shutdown mode was found to be the most appropriate option. After selecting the cold shutdown mode as a most suitable operational state of the plant, further studies of the vulnerability were done. In addition to possible direct damage to structures, that would cause release of radioactivity, two important subjects were considered: AC and DC power supply and the ultimate heat sink. A quick analysis during the crisis has shown that the consequences of a military attack against the plant by jet fighters could be serious, but with the proper preventive measures and preparedness the environmental consequences could be minimized.

Stem cell applications in military medicine.

Science.gov (United States)

Christopherson, Gregory T; Nesti, Leon J

2011-10-19

There are many similarities between health issues affecting military and civilian patient populations, with the exception of the relatively small but vital segment of active soldiers who experience high-energy blast injuries during combat. A rising incidence of major injuries from explosive devices in recent campaigns has further complicated treatment and recovery, highlighting the need for tissue regenerative options and intensifying interest in the possible role of stem cells for military medicine. In this review we outline the array of tissue-specific injuries typically seen in modern combat - as well as address a few complications unique to soldiers--and discuss the state of current stem cell research in addressing each area. Embryonic, induced-pluripotent and adult stem cell sources are defined, along with advantages and disadvantages unique to each cell type. More detailed stem cell sources are described in the context of each tissue of interest, including neural, cardiopulmonary, musculoskeletal and sensory tissues, with brief discussion of their potential role in regenerative medicine moving forward. Additional commentary is given to military stem cell applications aside from regenerative medicine, such as blood pharming, immunomodulation and drug screening, with an overview of stem cell banking and the unique opportunity provided by the military and civilian overlap of stem cell research.

The British Service Dhaulagiri Research Expedition (BSDMRE) took place from 27 March to 31 May 2016. The expedition involved 129 personnel, with voluntary participation in nine different study protocols. Studies were conducted in three research camps established at 3600, 4600 and 5140 m and involved taking and storing blood samples, cardiac echocardiography and investigations involving a balance plate. Research in this remote environment requires careful planning in order to provide a robust and resilient power plan. In this paper we aim to report the rationale for the choices we made in terms of power supply, the equipment used and potential military applicability. This is a descriptive account from the expedition members involved in planning and conducting the medical research. Power calculations were used to determine estimates of requirement prior to the expedition. The primary sources used to generate power were internal combustion engine (via petrol fuelled electric generators) and solar panels. Having been generated, power was stored using lithium-ion batteries. Special consideration was given to the storage of samples taken in the field, for which electric freezers and dry shippers were used. All equipment used functioned well during the expedition, with the challenges of altitude, temperature and transport all overcome due to extensive prior planning. Power was successfully generated, stored and delivered during the BSDMRE, allowing extensive medical research to be undertaken. The challenges faced and overcome are directly applicable to delivering military medical care in austere environments, and lessons learnt can help with the planning and delivery of future operations, training exercises or expeditions. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Full Text Available AIM: HIV/AIDS is a serious social pathology in public health, developmental and security problem since the productive and reproductive age group is mostly affected. This study was to determine the sero-prevalence of HIV among civilian applicants enrolling into military services of Nigeria army where youth’s vulnerability to HIV infection is very high. METHOD: A periodic cross sectional study was carried out amongst the civilian applicants undergoing recruitment into the Nigeria Army between January-February and July-August 2005, to determine their HIV status. Samples were collected from the applicants after interview to collect their socio-demographic characteristics. Data were analyzed with the aid of SPSS Version 12 and Chi square statistics was used to test for significance of association at P< 0.05. RESULTS: Out of the 9260 samples collected, 204 (2.2% tested positive for HIV with the highest proportion (73.5% occurring in the 22-25yrs bracket. Infection was detected in both sexes. The mean age of the applicants was 22yrs, with age range of 18-30 yrs and sex ratio of 1:7 (M: F. Age sex-specificity shows aged between 21-24 years have the highest number of HIV-antibody positivity. CONCLUSION: Antibody-positive applicants were identified in all the regions of Nigeria and the prevalence suggests that the epidemiology of transmission is changing both quantitatively and qualitatively because HIV now occurs commonly among young adults in their teens and late 20s and the impact of HIV on the military has grave consequences on the stability of Nigeria. The adoption of routine screening of applicants at point of recruitment, serving and retiring from the military can also be a source of data for understanding the epidemiology of this disease among the civilian and the military but in as HIV counseling and testing is an important continuum of the disease prevention and treatment, there is need to review Nigerian Army HIV and AIDS policy.

Very small HTGR nuclear power plant concepts for special terrestrial applications

International Nuclear Information System (INIS)

McDonald, C.F.; Goodjohn, A.J.

1983-01-01

The role of the very small nuclear power plant, of a few megawatts capacity, is perceived to be for special applications where an energy source as required but the following prevail: 1) no indigenous fossil fuel source, in long transport distances that add substantially to the cost of oil, coal in gas, and 3) secure long-term power production for defense applications with freedom from fuel supply lines. A small High Temperature Gas-Cooled reactor (HTGR) plant could provide the total energy needs for 1) a military installation, 2) an island base of strategic significance, 3) an industrial community or 4) an urban area. The small HTGR is regarded as a fixed-base installation (as opposed to a mobile system). All of the major components would be factory fabricated and transported to the site where emphasis would be placed on minimizing the construction time. The very small HTGR plant, currently in an early stage of design definition, has the potential for meeting the unique needs of the small energy user in both the military and private sectors. The plant may find acceptance for specialized applications in the industrialized nations and to meet the energy needs of developing nations. Emphasis in the design has been placed on safety, simplicity and compactness

2016-12-01

Stress Management Training programs are increasingly being adopted in the military field for resilience empowerment and primary stress prevention. In the last several years, advanced technologies (virtual reality in particular) have been integrated in order to develop more innovative and effective stress training programs for military personnel, including soldiers, pilots, and other aircrew professionals. This systematic review describes experimental studies that have been conducted in recent years to test the effectiveness of virtual reality-based Stress Management Training programs developed for military personnel. This promising state-of-the-art technology has the potential to be a successful new approach in empowering soldiers and increasing their resilience to stress. To provide an overview from 2001 to 2016 of the application of virtual reality for Stress Management Training programs developed for the military, a computer-based search for relevant publications was performed in several databases. Databases used in the search were PsycINFO, Web of Science (Web of Knowledge), PubMed, and Medline. The search string was: ("Virtual Reality") AND ("Military") AND ["Stress Training" OR ("Stress Management")]. There were 14 studies that met the inclusion criteria and were included in the review. The main observation to be drawn from this review is that virtual reality can provide interactive Stress Management Training to decrease levels of perceived stress and negative affect in military personnel. This technology appears to be a promising tool for assessing individuals' resilience to stress and for identifying the impact that stress can have on physiological reactivity and performance.Pallavicini F, Argenton L, Toniazzi N, Aceti L, Mantovani F.

Defense nuclear energy systems selection methodology for civil nuclear power applications

International Nuclear Information System (INIS)

Scarborough, J.C.

1986-01-01

A methodology developed to select a preferred nuclear power system for a US Department of Defense (DOD) application has been used to evaluate preferred nuclear power systems for a remote island community in Southeast Asia. The plant would provide ∼10 MW of electric power, possibly low-temperature process heat for the local community, and would supplement existing island diesel electric capacity. The nuclear power system evaluation procedure was evolved from a disciplined methodology for ranking ten nuclear power designs under joint development by the US Department of Energy (DOE) and DOD. These included six designs proposed by industry for the Secure Military Power Plant Program (now termed Multimegawatt Terrestrial Reactor Program), the SP-100 Program, the North Warning System Program, and the Modular Advanced High-Temperature Gas-Cooled Reactor (HTGR) and Liquid-Metal Reactor (LMR) programs. The 15 evaluation criteria established for the civil application were generally similar to those developed and used for the defense energy systems evaluation, except that the weighting factor applied to each individual criterion differed. The criteria and their weighting (importance) functions for the civil application are described

High-energy-density hydrogen-halogen fuel cells for advanced military applications

International Nuclear Information System (INIS)

Balko, E.N.; McElroy, J.F.

1981-01-01

It is pointed out that hydrogen-halogen fuel cell systems are particularly suited for an employment as ground power sources for military applications. The large cell potential and reversible characteristics of the H 2 Cl 2 and H 2 Br 2 couples permit high energy storage density and efficient energy conversion. When used as flow batteries, the fluid nature of the reactants in the hydrogen-halogen systems has several advantages over power sources which involve solid phases. Very deep discharge is possible without degradation of subsequent performance, and energy storage capacity is limited only by the external reactant storage volume. Very rapid chemical recharging is possible through replenishment of the reactant supply. A number of H 2 Cl 2 and H 2 Br 2 fuel cell systems have been studied. These systems use the same solid polymer electrolyte (SPE) cell technology originally developed for H2/O2 fuel cells. The results of the investigation are illustrated with the aid of a number of graphs

2015-08-01

A design of an Instantaneous High Power Supply System (IHPSS) with a power distribution management (PDM) for portable military devices is newly addressed. The system includes a power board and a hybrid battery that can not only supply instantaneous high power but also maintain stable operation at critical low temperature (-30 °C). The power leakage and battery overcharge are effectively prevented by the optimal PDM. The performance of the proposed system under the required pulse loads and the operating conditions of a Korean Advanced Combat Rifle employed in the battlefield is modeled with simulations and verified experimentally. The system with the IHPSS charged the fuse setter with 1.7 times higher voltage (8.6 V) than the one without (5.4 V) under the pulse discharging rate (1 A at 0.5 duty, 1 ms) for 500 ms.

Zutavern, F.J.; O'Malley, M.W.; Ruebush, M.H.; Rinehart, L.F.; Loubriel, G.M.; Babcock, S.R.; Denison, G.J.

1998-04-01

A compact, short pulse, repetitive accelerator has many useful military and commercial applications in biological counter proliferation, materials processing, radiography, and sterilization (medical instruments, waste, and food). The goal of this project was to develop and demonstrate a small, 700 kV accelerator, which can produce 7 kA particle beams with pulse lengths of 10--30 ns at rates up to 50 Hz. At reduced power levels, longer pulses or higher repetition rates (up to 10 kHz) could be achieved. Two switching technologies were tested: (1) spark gaps, which have been used to build low repetition rate accelerators for many years; and (2) high gain photoconductive semiconductor switches (PCSS), a new solid state switching technology. This plan was economical, because it used existing hardware for the accelerator, and the PCSS material and fabrication for one module was relatively inexpensive. It was research oriented, because it provided a test bed to examine the utility of other emerging switching technologies, such as magnetic switches. At full power, the accelerator will produce 700 kV and 7 kA with either the spark gap or PCSS pulser

2009-01-01

In order to successfully support current and future US military operations in coastal zones, geospatial information must be rapidly integrated and analyzed to meet ongoing force structure evolution and new mission directives. Coastal zones in a military-operational environment are complex regions that include sea, land and air features that demand high-volume databases of extreme detail within relatively narrow geographic corridors. Static products in the form of analog maps at varying scales traditionally have been used by military commanders and their operational planners. The rapidly changing battlefield of 21st Century warfare, however, demands dynamic mapping solutions. Commercial geographic information system (GIS) software for military-specific applications is now being developed and employed with digital databases to provide customized digital maps of variable scale, content and symbolization tailored to unique demands of military units. Research conducted by the Center for Remote Sensing and Mapping Science at the University of Georgia demonstrated the utility of GIS-based analysis and digital map creation when developing large-scale (1:10,000) products from littoral warfare databases. The methodology employed-selection of data sources (including high resolution commercial images and Lidar), establishment of analysis/modeling parameters, conduct of vehicle mobility analysis, development of models and generation of products (such as a continuous sea-land DEM and geo-visualization of changing shorelines with tidal levels)-is discussed. Based on observations and identified needs from the National Geospatial-Intelligence Agency, formerly the National Imagery and Mapping Agency, and the Department of Defense, prototype GIS models for military operations in sea, land and air environments were created from multiple data sets of a study area at US Marine Corps Base Camp Lejeune, North Carolina.

The temperature distribution of the TEG is analyzed based on an experimental setup, and the temperature uniformity optimization method is performed by chipping peak off and filling valley is taken to validate the improved output power. An automobile exhaust thermoelectric generator (AETEG using four TEGs connected thermally in parallel and electrically in series is assembled into a prototype military SUV, its temperature distribution, output voltage, output power, system efficiency, inner resistance, and backpressure is analyzed, and several important influencing factors such as vehicle speed, clamping pressure, engine coolant flow rate, and ambient temperature on its output performance are tested. Experimental results demonstrate that higher vehicle speed, larger clamping pressure, faster engine coolant flow rate and lower ambient temperature can enhance the overall output performance, but the ambient temperature and coolant flow rate are less significant. The maximum output power of AETEG is 646.26 W, the corresponding conversion efficiency is 1.03%, and the increased backpressure changes from 1681 Pa to 1807 Pa when the highest vehicle speed is 125 km/h.

Wireless sensor network (WSN) is an ad-hoc network technology comprising even thousands of autonomic and self-organizing nodes that combine environmental sensing, data processing, and wireless networking. The applications for sensor networks range from home and industrial environments to military uses. Unlike the traditional computer networks, a WSN is application-oriented and deployed for a specific task. WSNs are data centric, which means that messages are not send to individual nodes but to geographical locations or regions based on the data content. A WSN node is typically battery powered and characterized by extremely small size and low cost. As a result, the processing power, memory, and energy resources of an individual sensor node are limited. However, the feasibility of a WSN lies on the collaboration between the nodes. A reference WSN node comprises a Micro-Controller Unit (MCU) having few Million Instructions Per Second (MIPS) processing speed, tens of kilobytes program memory, few kilobytes data m...

Full Text Available Military-political issues is an important area of research work at MGIMO. The difference in this direction from the classical international specialization is that it is at the intersection of several disciplines: military science, military-technical and military-industrial as well as International Relations. A specialist in military and political issues should not only be an expert in the field of international relations and diplomacy, but also have a deep knowledge of military-technical issues to understand the basic trends in the development of scientific and technological progress and its impact on the balance of forces in the world. Global changes in the balance of power and the nature of the conflict, the emergence of new types of weapons are changing the basic methods and approaches to the art of war, which requires a science-based perspective on problem solving and multi-disciplinary approach in achieving the goals. Military and political studies allow us to understand how the development of military technology and military organization of the state affected by the political situation in the world, the national security of the country and its place in the system of international relations. Military-political research has been developing at MGIMO for a few decades. It laid down the basis for a scientific school of political-military studies. Its founding fathers were such prominent scholars of international affairs, as I.G. Usachyov, A.D. Nikonov, A.G. Arbatov, V.G. Baranovsky, V.M. Kulagin, A.N. Nikitin and other well-known experts. Their work covers a wide range of military and political issues, including the topics of arms control and disarmament, international, and especially European security, military policy, NATO, the Western military-political doctrines and their practical application. Now the lead in the development of this research at MGIMO has taken Center for Military-Political Studies, which became a concentration of relevant

Todays, with the energy supplies and global warming concerns, nuclear energy in making a come-back, witness the numerous nuclear programs launched or re-launched in the US, in Europe, China and India. In parallel, on the military side, the deterrence strategy remains in the center of security politics of big powers. This atlas takes stock of the overall issues linked with the nuclear technology: production, civil applications (power generation, medicine etc..), military usages (naval propulsion, weapons). It answers the main questions of this complex world, often dominated by secrecy: who does what in the nuclear domain in France? Is an accident, like the Chernobyl's one, possible today in Europe? What solutions for radioactive wastes? Do we take risks when we export our reactor technologies to Middle-East countries? Are we at the dawn of a new arms rush? What do international agreements foresee in this domain? Taking into account the costs, the hazards and the advantages of nuclear industry, the atlas shows that it is possible to establish solid technical and legal barriers between its civil and military sides.

High-power free-electron lasers-technology and future applications

Science.gov (United States)

Socol, Yehoshua

2013-03-01

Free-electron laser (FEL) is an all-electric, high-power, high beam-quality source of coherent radiation, tunable - unlike other laser sources - at any wavelength within wide spectral region from hard X-rays to far-IR and beyond. After the initial push in the framework of the “Star Wars” program, the FEL technology benefited from decades of R&D and scientific applications. Currently, there are clear signs that the FEL technology reached maturity, enabling real-world applications. E.g., successful and unexpectedly smooth commissioning of the world-first X-ray FEL in 2010 increased in one blow by more than an order of magnitude (40×) wavelength region available by FEL technology and thus demonstrated that the theoretical predictions just keep true in real machines. Experience of ordering turn-key electron beamlines from commercial companies is a further demonstration of the FEL technology maturity. Moreover, successful commissioning of the world-first multi-turn energy-recovery linac demonstrated feasibility of reducing FEL size, cost and power consumption by probably an order of magnitude in respect to previous configurations, opening way to applications, previously considered as non-feasible. This review takes engineer-oriented approach to discuss the FEL technology issues, keeping in mind applications in the fields of military and aerospace, next generation semiconductor lithography, photo-chemistry and isotope separation.

Research and application of pulsed-power technology

Yonas, G.

1980-01-01

Pulsed-power technology relating to that branch which was stimulated by military applications in the 1960's is addressed. A history of the development and characteristics of some devices producing intense electron and ion beams which resulted in Sandia's particle beam fusion program is presented. These include Hermes II, Aurora, Hydra, and Proto II. Research on inertial confinement fusion ignition is described, and the most critical issue in ICF today still is the demonstration of ignition and efficient burnup of a small amount of thermonuclear fuel. Progress on the Sandia particle beam fusion accelerator (PBFA I and II) is reported, but already plans are underway to further upgrade the device and if these modifications are carried out in 1983, fusion ignition concepts may be tested by 1985. Fusion could possibly provide an inexhaustible supply of energy in the next century

Bunea, Cornel; Mazzuchi, Thomas A.; Sarkani, Shahram; Chang, H.-C.

2008-01-01

This paper focuses on analysis techniques of modern reliability databases, with an application to military system data. The analysis of military system data base consists of the following steps: clean the data and perform operation on it in order to obtain good estimators; present simple plots of data; analyze the data with statistical and probabilistic methods. Each step is dealt with separately and the main results are presented. Competing risks theory is advocated as the mathematical support for the analysis. The general framework of competing risks theory is presented together with simple independent and dependent competing risks models available in literature. These models are used to identify the reliability and maintenance indicators required by the operating personnel. Model selection is based on graphical interpretation of plotted data

Application of military uncooled infrared sensors to homeland defense

Science.gov (United States)

Hornberger, Chris

2002-08-01

During the early 1990's, uncooled microbolometer thermal imaging technology began a journey from Government and corporate laboratories to practical application in addressing military, Government, and commercial customer needs. Today, that transition could arguably be considered complete, punctuated by BAE SYSTEMS' delivery of the 10,000th microbolometer camera on 12 February 2002. While microbolometer developmental research continues to advance the state-of-the-art at an ever increasing pace, uncooled infrared cameras are widely deployed serving society in meaningful ways; from preventative maintenance and process inspection to law enforcement and rescue operations. Following last years terrorist attacks in New York and Virginia, President Bush appointed Governor Ridge to lead federal coordination efforts for defense of the homeland. While uncooled microbolometer sensors served in Homeland Security long before September 2001, it is certain that new applications will be identified for surveillance, security, law enforcement and protection needs. In this paper we will describe advances in military uncooled infrared sensor technology and how these sensors can serve in the role of Homeland Defense. Developments in uncooled sensors that will be described include the rugged performance validation of a thermal weapon sight and head-mounted imager. We will look at those areas of Homeland Defense that are most likely to benefit from the application of uncooled microbolometer thermal imaging sensor technology. These include: a) search & rescue camera systems, b) handheld surveillance systems and c) hands-free camera systems.

Applications of nuclear-powered thermoelectric generators in space

International Nuclear Information System (INIS)

Rowe, D.M.

1991-01-01

The source of electrical power which enables information to be transmitted from the space crafts Voyager 1 and 2 back to Earth after a time period of more than a decade and at a distance of more than a billion miles is known as an RTG (radioisotope thermoelectric generator). It utilises the Seebeck effect in producing electricity from heat. In essence it consists of a large number of semiconductor thermocouples connected electrically in series and thermally in parallel. A temperature difference is maintained across the thermocouples by providing a heat source, which in the case of an RTG is a radioactive isotope, and the heat sink is space. The combination of an energy-conversion system, free of moving parts and a long-life, high energy-density heat source, provides a supply of electrical power typically in the range of tens to hundred of watts and which operates reliably over extended periods of time. An electric power source, based upon thermoelectric conversion by which utilises a nuclear reactor as a heat source, has also been deployed in space and a 100-kW system is being developed to provide electrical power to a variety of commercial and military projects including SDI. Developments in thermoelectrics that have taken place in the western world during the past 30 years are primarily due to United States interest and involvement in the exploration of space. This paper reviews US applications of nuclear-powered thermoelectric generators in space. (author)

The formation of fission products and plutonium in reactors is briefly described, followed by a short general discussion of reactor safety. The interaction of reactor safety and radioactive release considerations with military and civil defence is thereafter discussed. Reactors and other nuclear plants are factors which must be taken into account in the defence of the district around the site, and as potential targets of both conventional and guerilla attacks and sabotage, requiring special defence. The radiological hazards arising from serious damage to a power reactor by conventional weapons are briefly discussed, and the benefits of underground siting evaluated. Finally the author discusses the significance of the IAEA safeguards work as a preventive factor. (JIW)

Active photonic sensor communication cable for field application of optical data and power transmission

Science.gov (United States)

Suthau, Eike; Rieske, Ralf; Zerna, Thomas

2014-10-01

Omitting electrically conducting wires for sensor communication and power supply promises protection for sensor systems and monitored structures against lightning or high voltages, prevention of explosion hazards, and reduction of susceptibility to tampering. The ability to photonically power remote systems opens up the full range of electrical sensors. Power-over-fiber is an attractive option in electromagnetically sensitive environments, particularly for longterm, maintenance-free applications. It can deliver uninterrupted power sufficient for elaborate sensors, data processing or even actuators alongside continuous high speed data communication for remote sensor application. This paper proposes an active photonic sensor communication system, which combines the advantages of optical data links in terms of immunity to electromagnetic interference (EMI), high bandwidth, hardiness against tampering or eavesdropping, and low cable weight with the robustness one has come to expect from industrial or military electrical connectors. An application specific integrated circuit (ASIC) is presented that implements a closed-loop regulation of the sensor power supply to guarantee continuous, reliable data communications while maintaining a highly efficient, adaptive sensor supply scheme. It is demonstrated that the resulting novel photonic sensor communication cable can handle sensors and actuators differing orders of magnitude with respect to power consumption. The miniaturization of the electro-optical converters and driving electronics is as important to the presented development as the energy efficiency of the detached, optically powered sensor node. For this reason, a novel photonic packaging technology based on wafer-level assembly of the laser power converters by means of passive alignment will be disclosed in this paper.

Biomarkers of PTSD: military applications and considerations.

Science.gov (United States)

Lehrner, Amy; Yehuda, Rachel

2014-01-01

Although there are no established biomarkers for posttraumatic stress disorder (PTSD) as yet, biological investigations of PTSD have made progress identifying the pathophysiology of PTSD. Given the biological and clinical complexity of PTSD, it is increasingly unlikely that a single biomarker of disease will be identified. Rather, investigations will more likely identify different biomarkers that indicate the presence of clinically significant PTSD symptoms, associate with risk for PTSD following trauma exposure, and predict or identify recovery. While there has been much interest in PTSD biomarkers, there has been less discussion of their potential clinical applications, and of the social, legal, and ethical implications of such biomarkers. This article will discuss possible applications of PTSD biomarkers, including the social, legal, and ethical implications of such biomarkers, with an emphasis on military applications. Literature on applications of PTSD biomarkers and on potential ethical and legal implications will be reviewed. Biologically informed research findings hold promise for prevention, assessment, treatment planning, and the development of prophylactic and treatment interventions. As with any biological indicator of disorder, there are potentially positive and negative clinical, social, legal, and ethical consequences of using such biomarkers. Potential clinical applications of PTSD biomarkers hold promise for clinicians, patients, and employers. The search for biomarkers of PTSD should occur in tandem with an interdisciplinary discussion regarding the potential implications of applying biological findings in clinical and employment settings.

Solar Electric Propulsion (SEP) Tug Power System Considerations

Science.gov (United States)

Kerslake, Thomas W.; Bury, Kristen M.; Hojinicki, Jeffrey S.; Sajdak, Adam M.; Scheiddegger, Robert J.

2011-01-01

Solar electric propulsion (SEP) technology is truly at the "intersection of commercial and military space" as well as the intersection of NASA robotic and human space missions. Building on the use of SEP for geosynchronous spacecraft station keeping, there are numerous potential commercial and military mission applications for SEP stages operating in Earth orbit. At NASA, there is a resurgence of interest in robotic SEP missions for Earth orbit raising applications, 1-AU class heliocentric missions to near Earth objects (NEOs) and SEP spacecraft technology demonstrations. Beyond these nearer term robotic missions, potential future human space flight missions to NEOs with high-power SEP stages are being considered. To enhance or enable this broad class of commercial, military and NASA missions, advancements in the power level and performance of SEP technologies are needed. This presentation will focus on design considerations for the solar photovoltaic array (PVA) and electric power system (EPS) vital to the design and operation of an SEP stage. The engineering and programmatic pros and cons of various PVA and EPS technologies and architectures will be discussed in the context of operating voltage and power levels. The impacts of PVA and EPS design options on the remaining SEP stage subsystem designs, as well as spacecraft operations, will also be discussed.

Proliferation of nuclear weapons. Civilian and military exploitation of nuclear power

International Nuclear Information System (INIS)

Andresen, S.; Kongstad, S.

1978-01-01

Following brief technical and historical surveys the structure of the nuclear power market is discussed. In the 1970s a major change has been the decline of USA's virtual monopoly and the active entry of West Germany, France and Canada into the merket. Another development has been the commercialisation of progressively more of the fuel cycle, vide the agreements between Brazil and W. Germany, and Pakistan and France. These tendencies, added to the general spread of nuclear technologial ability and the adoption of nuclear power in more and more developing countries is presumed to increase the danger of nuclear weapon proliferation. The motives for, and means of, such proliferation are analysed. The tripartite agreement between Brazil, W. Germany and USA is discussed in great detail to illustrate the situation. The role of the NPT is not found to be significant. It is concluded that though proliferation may be inevitible, the motives may be for prestige and negotiating power, rather than use, and that the policy of the superpowers seems in the long run to lead to a reduction of their military dominance, and possible also their economic and political position in the international community.

Canadian Model of Military Leadership as a Successful Mixture of Civilian and Military Experiences

Directory of Open Access Journals (Sweden)

Piotr Malinowski

2015-06-01

Full Text Available The origins of military leadership are rooted in ancient times and its embodiment are great chieftains and commanders. However, since the moment when in organisation and management sciences the civil theories of leadership started to emerge, the military forces have incorporated their solutions to structure the assumptions of new, coherent and effective models of military leadership. A good example of such solutions is the Canadian model of military leadership, competently merging the civil theories with experience and needs of the military environment. This solution may be a perfect example of effective application of leadership theory to modify the existing national model of military leadership and construct a more efficient one.

Forecasting military expenditure

Directory of Open Access Journals (Sweden)

Tobias Böhmelt

2014-05-01

Full Text Available To what extent do frequently cited determinants of military spending allow us to predict and forecast future levels of expenditure? The authors draw on the data and specifications of a recent model on military expenditure and assess the predictive power of its variables using in-sample predictions, out-of-sample forecasts and Bayesian model averaging. To this end, this paper provides guidelines for prediction exercises in general using these three techniques. More substantially, however, the findings emphasize that previous levels of military spending as well as a country’s institutional and economic characteristics particularly improve our ability to predict future levels of investment in the military. Variables pertaining to the international security environment also matter, but seem less important. In addition, the results highlight that the updated model, which drops weak predictors, is not only more parsimonious, but also slightly more accurate than the original specification.

The design and development of CO2 medium-level laser power calibration system for industrial and medical applications in Thailand

Science.gov (United States)

Nontapot, Kanokwan

2018-03-01

The carbon dioxide laser (CO2 laser) is one of the most useful and is the highest CW laser at the present. The laser produces infrared light at 10.6 um. Due to its high power, CO2 lasers are usually used in industrial applications such as cutting and welding, or for engraving at less power. CO2 lasers are also used widely in medical applications, such as laser surgery, skin resurfacing, and removing mold, due to water (biological tissue) absorb light at this wavelength very well. CO2 lasers are also used as LIDAR laser source for military range finding applications because of the transparency of the atmosphere to infrared light. Due to the increasing use of CO2 lasers laser in industrial and medical applications in Thailand, the National Institute of Metrology (Thailand) has set up a CO2 laser power calibration system and provide calibration service to customers this year. The service support calibration of medium-level laser power at wavelength of 10.6 um and at power range 100 mW-10W. The design and development of the calibration system will be presented.

Cost of nuclear power generation judged by power rate

International Nuclear Information System (INIS)

Hirai, Takaharu

1981-01-01

According to estimation guidance, power rates in general are the proper cost plus the specific compensation and adjustment addition. However, the current system of power rates is of power-source development promotion type involving its tax. The structure of power rate determination must be restudied now especially in connection of nuclear power generation. The cost of nuclear power generation as viewed from power rate is discussed as follows: the fear of military application of power plants, rising plant construction costs, the loophole in fuel cost calculation, unreasonable unit power cost, depreciation and repair cost, business compensation, undue business compensation in nuclear power, the costs of nuclear waste management, doubt concerning nuclear power cost, personnel, pumping-up and power transmission costs in nuclear power, energy balance analysis, nuclear power viewed in entropy, the suppression of power consumption.

Military Strategy Of India

Directory of Open Access Journals (Sweden)

M. S. Zaitsev

2017-01-01

Full Text Available The article analyzes the evolution of military strategy of the Republic of India and key factors that influences its development. New Delhi keeps an eye on the balance of power in South Asia to create favorable conditions for its economic and social development, yet the remaining threats and new challenges still undermine the security and stability in India. The ambitions of China aspiring to power in Asia-Pacific region, combined with its immense military build-up and territorial disputes, cause disturbance in New Delhi. The remaining tensions between India and Pakistan also cause often border skirmishes and medium-scale conflicts. Close relations between China and Pakistan, labeled as “all-weather friendship”, are a source of major concern for India. The fact that both Beijing and Islamabad wield nuclear weapons means that without effective mechanisms of nuclear deterrence any military conflict may turn into a full-scale nuclear war. Terrorist activities and insurgency in the Indian state of Jammu and Kashmir and in the North-Eastern regions of the country, along with maritime piracy and illicit drug trafficking contribute to the complicated nature of the challenges to the Indian security. Indian military strategy is considered as a combination of the army doctrine, maritime doctrine and nuclear doctrine. The Indian political and military leadership wants to meet the challenges of changing geopolitical environment and thus continuously adapts its strategy. However, there is still a gap between theory and practice: Indian armed forces lack the capacity to implement the declared goals because of bulky bureaucratic system, outdated military equipment and insufficient level of command and control. The government needs to mobilize political will and administrative resources to upgrade its defense sector to counter its security threats and challenges.

This paper is a roadmap to the exhaustive role of the newly emerging field of nanotechnology in various application and research areas. Some of the today's important topics are plasma, dielectric layer semiconductor, and carbon nanoparticle based technologies. Carbon nanotubes are very useful for the purpose of fabricating nano opto power devices. The basic concept behind tunneling of electrons has been utilized to define another scope of this technology, and thus came many quantum scale tunneling devices and elements. Fabrication of crystal semiconductors of high quality along with oxides of nano aspect would give rise to superior device performance and find applications such as LEDs, LASER, VLSI technology and also in highly efficient solar cells. Many nano-research based organizations are fully devoted to develop nano power cells, which would give birth to new battery cells, tunneling devises, with high power quality, longer lives, and higher activation rates. Different electronics industries as well as the military organizations would be largely benefited due to this major component and system design ideas of 'Smart Power' technologies. The contribution of nano scale power electronics would be realized in various fields like switching devices, electromechanical systems and quantum science. Such a sophisticated technology will have great impact on the modernization of robotics; space systems, automotive systems and many other fields. The highly emerging field of nanomedicine according to specialists would bring a dramatic revolution in the present century. However nanomedicine is nothing but an integration of biology, medicine and technology. Thermoelectric materials as been referred earlier also are used in case of implantable medical equipments for generation of electric power sufficient for those equipments.

In this paper a laminated waveguide fed DR Antenna is investigated. It can use for moderate power military applications. Cylindrical DRA is excited by two closely spaced asymmetric longitudinal slots on the broad wall of the laminated cavity are responsible for producing three different frequency bands. Parametric study of slots has been done with the help of commercial software ANSOFT HFSS. All the bands have sharp rejection. The final model of the antenna is simulated, fabricated and experimentally measured. Measured results are in quite accordant with design results. SIW feeding structures have small losses, moderate power handling capacity, low costs, compact sizes and can be seamlessly integrated with planar circuits. At all the bands 9.76 GHz, 10.53 GHz and 11.8 GHz resonant frequency, the antenna shows 56 MHz, 160 MHz, and 250 MHz impedance bandwidth (for VSWR<2) with 6 dB,6.2 dB and 6.8 dB gain respectively. Simulated and measured results reveal outstanding performance with a cross-polar level of 29 dB lower than that of the co-polar level at 9.76 GHz, the cross-polar level of 32 dB lower than that of the co-polar level at 10.53, GHz, and similarly cross-polar level of 30 dB lower than that of the co-polar level at 11.8 GHz.

Nuclear power is usually viewed as the flagship of nuclear technology. A nuclear power plant complex, visible and prominence, is iconic of the technology. That image makes its presence common knowledge to the extent that nuclear technology is equated almost totally with nuclear power by the general public. The downside of this visibility is that it becomes easy target in public misinformation programs. The non-power applications however are not visible, and devoid of icon. The non-power applications, therefore, can grow quite smoothly, attracting only little attention in the negative and in the positive senses. According to a study conducted in the USA in 2000 and in Japan in 2002, the socio-economic impact of non-power and power applications of nuclear technology are comparable. Involvement in non-power applications can be a good grounding for moving into power applications. This paper discusses the non-power nuclear technology applications and in what manner it can serve to prepare the introduction of nuclear power program. (Author)

Science.gov (United States)

Takaki, Koichi; Katsuki, Sunao

Recent progress of the industrial applications of pulsed power is reviewed in this paper. Repetitively operated pulsed power generators with a moderate peak power have been developed for industrial applications. These generators are reliable and low maintenance. Development of the pulsed power generators helps promote industrial applications of pulsed power for such things as food processing, medical treatment, water treatment, exhaust gas treatment, ozone generation, engine ignition, ion implantation and others. Here, industrial applications of pulsed power are classified by application for biological effects, for pulsed streamer discharges in gases, for pulsed discharges in liquid or liquid-mixture, and for bright radiation sources.

Knecht, Sean D.; Mead, Franklin B.; Thomas, Robert E.; Miley, George H.; Froning, David

2006-01-01

The objective of this study was to perform a parametric evaluation of the performance and interface characteristics of a dense plasma focus (DPF) fusion system in support of a USAF advanced military aerospace vehicle concept study. This vehicle is an aerospace plane that combines clean 'aneutronic' dense plasma focus (DPF) fusion power and propulsion technology, with advanced 'lifting body'-like airframe configurations utilizing air-breathing MHD propulsion and power technology within a reusable single-stage-to-orbit (SSTO) vehicle. The applied approach was to evaluate the fusion system details (geometry, power, T/W, system mass, etc.) of a baseline p-11B DPF propulsion device with Q = 3.0 and thruster efficiency, ηprop = 90% for a range of thrust, Isp and capacitor specific energy values. The baseline details were then kept constant and the values of Q and ηprop were varied to evaluate excess power generation for communication systems, pulsed-train plasmoid weapons, ultrahigh-power lasers, and gravity devices. Thrust values were varied between 100 kN and 1,000 kN with Isp of 1,500 s and 2,000 s, while capacitor specific energy was varied from 1 - 15 kJ/kg. Q was varied from 3.0 to 6.0, resulting in gigawatts of excess power. Thruster efficiency was varied from 0.9 to 1.0, resulting in hundreds of megawatts of excess power. Resulting system masses were on the order of 10's to 100's of metric tons with thrust-to-weight ratios ranging from 2.1 to 44.1, depending on capacitor specific energy. Such a high thrust/high Isp system with a high power generation capability would allow military versatility in sub-orbital space, as early as 2025, and beyond as early as 2050. This paper presents the results that coincide with a total system mass between 15 and 20 metric tons

Nationally, the number of internal medicine physicians practicing in primary care has decreased amidst increasing interest in hospitalist medicine. Current priorities in the Military Health System include access to primary care and retention of trained personnel. Recently, we have conducted a study of military internal medicine residents' decision to enter infectious disease. As part of our larger effort, we saw an opportunity to characterize factors impacting decision making of internal medicine residents' desire to apply for subspecialty training and to extend active duty service obligations. Questions were developed after discussion with various military graduate medical education and internal medicine leaders, underwent external review, and were added to a larger question set. The survey link was distributed electronically to all U.S. military affiliated residencies' graduating internal medicine residents in December 2016-January 2017. Data were analyzed by decision to apply to fellowship and decision to extend military obligation using Fisher's exact test or Pearon's chi-square test. Sixty-eight residents from 10 of 11 military residency programs responded, for a response rate of 51%. The majority (62%) applied to fellowship to start after residency completion. Reasons cited for applying to fellowship included wanting to become a specialist as soon as possible (74%), wishing to avoid being a general internist (57%), and because they are unable to practice as a hospitalist in the military (52%). Fellowship applicants were more likely to plan to extend their military obligation than non-applicants, as did those with longer duration of military commitments. No other factors, including Uniformed Services University attendance or participation in undergraduate military experiences, were found to impact plan to extend active duty service commitment. The majority of graduating internal medicine residents apply for fellowship and report a desire to avoid being a

Soft power geopolitics: how does the diminishing utility of military power affect the Russia – West confrontation over the “Common Neighbourhood”

Directory of Open Access Journals (Sweden)

Vasif HUSEYNOV

2016-12-01

Full Text Available This paper is based on the fact that a number of factors, but particularly the restricting utility of military force between great powers, increase the significance of soft power as a tool both for legitimization and expansion in international relations in general, and in the West – Russia confrontation over the “common (or shared neighbourhood” in particular. It explores how this fact affects the policies of the Western powers and Russia within the frame of the confrontation they are in. The paper narrows down its analytical focus on the efforts of the Kremlin to affect the public opinion in its neighbourhood and to counter Western soft power. It is argued that the Ukraine crisis has affected Russia’s perception of soft power, re-constructed its counter-revolutionary agenda, and increased the profile of propaganda in its foreign policy. The paper concludes that the soft power competition between Russia and West and the policies of the two powers to win over the hearts and minds of people in the shared neighbourhood re-define the character of geopolitical games in the Former Soviet Union.

The japan a nuclear power?

Cumin, D.; Joubert, J.P.

2003-01-01

This work analyzes the Japan nuclear policy, in the frame of its foreign and safety policy in Pacific Asia, since the end of the cold war, especially the relations with the Usa and China. The Japan is a civil power because it has submitted the military institution to juridical restrictions and because it does not rely on the armed force to promote its national interests. The anti nuclear speech is joined with the acknowledgement of the dissuasion necessity, of the control of industrial processes and energy channels susceptible of military applications. Cultivating the ambiguity, the Japanese government can send a dissuasive message, perfectly legible, kind of communication of latent intimidation constituted by the virtual nuclear power of a state that takes part to the non proliferation treaty.

Benford, J.; Swegle, J.

1993-01-01

The authors address a number of applications for HPM technology. There is a strong symbiotic relationship between a developing technology and its emerging applications. New technologies can generate new applications. Conversely, applications can demand development of new technological capability. High-power microwave generating systems come with size and weight penalties and problems associated with the x-radiation and collection of the electron beam. Acceptance of these difficulties requires the identification of a set of applications for which high-power operation is either demanded or results in significant improvements in peRFormance. The authors identify the following applications, and discuss their requirements and operational issues: (1) High-energy RF acceleration; (2) Atmospheric modification (both to produce artificial ionospheric mirrors for radio waves and to save the ozone layer); (3) Radar; (4) Electronic warfare; and (5) Laser pumping. In addition, they discuss several applications requiring high average power than border on HPM, power beaming and plasma heating

Pending crisis in Russian civil military relations

Energy Technology Data Exchange (ETDEWEB)

Ball, D.Y.

1997-10-01

A key issue in the study of civil-military relations has been how to create a military sufficiently strong to ensure security from external threats while simultaneously preventing the military from using its preponderance of power in the domestic arena. This dilemma arises from the fear engendered by a large armed force created to combat foreign threats, but which is also inherently a threat to the society that created it. In Russia, however, the question is not how the civilian leadership can keep the military out of politics, but how the military can keep the leadership from politicizing the armed forces. The Russian military has no interest in resolving Russia`s domestic political problems. It is a professional military that prefers to leave politics to the politicians, and to carry out its mission of defending the nation against external attack. But the lack of responsible central leadership and the poor state of the economy are driving the military toward involvement in domestic politics if for no other reason than to ensure its own survival.

MILITARY COMPETITION BETWEEN FRIENDS? HEGEMONIC DEVELOPMENT AND MILITARY SPENDING AMONG EIGHT WESTERN DEMOCRACIES, 1920-1938

Directory of Open Access Journals (Sweden)

Jari Eloranta

2001-01-01

Full Text Available This article explores the complicated phenomenon of military spending among a sample of eight Western democracies in the interwar period by analyzing especially the possibility of economic and/or military competition between the Western Great Powers and the ensuing impacts on the smaller states included here. The hegemonic paradigm suggested by e.g. Paul Kennedy predicts that the economic leader in a system will increasingly invest on maintaining security; thus eventually bringing economic growth to a halt. The military spending patterns respective of economic growth at first seem to suggest that not only the totalitarian states, as is the traditional view, but also the UK and France stepped in to fill the void created by the lack of American leadership. However, the military expenditures of these nations were too low to warrant the conclusion that they had any impact on their respective economic performance. This result is also verified here by employing Granger non-causality tests between the military spending and economic growth variables. Moreover, regression analysis on the military spending variables for the UK and France points towards competition on the level. The smaller states, respectively, seemed to follow the UK and France fairly closely in their military spending decisions.

Celis del A, L.; Palacios, J.; Rivero, T.; Valero, D.

2016-09-01

The versatility of drones is one of the strengths that have led to the rapid development of this technology, as they adapt relatively easily to new applications, presenting considerable advantages such as greater energy efficiency, longer life and a significant lower operation cost than manned systems. The current applications of the drones, in addition to the military, are very wide and varied. The nuclear industry represents an important area of opportunity for drones, mainly in response to radiological emergencies, since in this case there is a latent risk of the general population being exposed to high radiation doses. Drones can be used in environments with high chemical and radiological toxicity without endangering human lives. Some of the possible applications of the drones in a nuclear power plant are: perimeter surveillance in physical security, where equipped with a high definition camera can be used as support to physical security systems in general; visual inspection at sites, structures, equipment and pipelines, etc., as part of preventive maintenance in order to avoid the loss of material due to corrosion, oxidation, cracking, subsidence; the visual inspection through thermo-graphic images to be able to detect hot spots in some critical element; measurement and radiological mapping on surfaces to maintain monitoring of radiological safety at nuclear power plant facilities; the monitoring of environmental parameters and the Environmental Impact Assessment to obtain important information to determine the environmental impact of a given area; and accident support by providing information that allows staff to size the magnitude of the damage.

Todays, with the energy supplies and global warming concerns, nuclear energy in making a come-back, witness the numerous nuclear programs launched or re-launched in the US, in Europe, China and India. In parallel, on the military side, the deterrence strategy remains in the center of security politics of big powers. This atlas takes stock of the overall issues linked with the nuclear technology: production, civil applications (power generation, medicine etc..), military usages (naval propulsion, weapons). It answers the main questions of this complex world, often dominated by secrecy: who does what in the nuclear domain in France? Is an accident, like the Chernobyl's one, possible today in Europe? What solutions for radioactive wastes? Do we take risks when we export our reactor technologies to Middle-East countries? Are we at the dawn of a new arms rush? What do international agreements foresee in this domain? Taking into account the costs, the hazards and the advantages of nuclear industry, the atlas shows that it is possible to establish solid technical and legal barriers between its civil and military sides.

High Power High Efficiency Diode Laser Stack for Processing

Science.gov (United States)

Gu, Yuanyuan; Lu, Hui; Fu, Yueming; Cui, Yan

2018-03-01

High-power diode lasers based on GaAs semiconductor bars are well established as reliable and highly efficient laser sources. As diode laser is simple in structure, small size, longer life expectancy with the advantages of low prices, it is widely used in the industry processing, such as heat treating, welding, hardening, cladding and so on. Respectively, diode laser could make it possible to establish the practical application because of rectangular beam patterns which are suitable to make fine bead with less power. At this power level, it can have many important applications, such as surgery, welding of polymers, soldering, coatings and surface treatment of metals. But there are some applications, which require much higher power and brightness, e.g. hardening, key hole welding, cutting and metal welding. In addition, High power diode lasers in the military field also have important applications. So all developed countries have attached great importance to high-power diode laser system and its applications. This is mainly due their low performance. In this paper we will introduce the structure and the principle of the high power diode stack.

Future trends in commercial and military systems

Science.gov (United States)

Bond, F. E.

Commercial and military satellite communication systems are addressed, with a review of current applications and typical communication characteristics of the space and earth segments. Drivers for the development of future commercial systems include: the pervasion of digital techniques and services, growing orbit and frequency congestion, demand for more entertainment, and the large potential market for commercial 'roof-top' service. For military systems, survivability, improved flexibility, and the need for service to small mobile terminals are the principal factors involved. Technical trends include the use of higher frequency bands, multibeam antennas and a significant increase in the application of onboard processing. Military systems will employ a variety of techniques to counter both physical and electronic threats. The use of redundant transmission paths is a particularly effective approach. Successful implementation requires transmission standards to achieve the required interoperability among the pertinent networks. For both the military and commercial sectors, the trend toward larger numbers of terminals and more complex spacecraft is still persisting.

This paper discusses a 10 KWe dual-mode space power system concept which has been identified and is based on INEL's Small Externally-fueled Heat Pipe Thermionic Reactor (SEHPTR) concept. This power system will enhance user capabilities by providing reliable electric power and by providing two propulsion systems; electric power for an arc-jet electric propulsion system and direct thrust by heating hydrogen propellant inside the reactor. The low thrust electric thrusters allow efficient station keeping and long-term maneuvering. This paper will focus on the nuclear power system design, including: the reactor with its UO 2 fuel in tungsten clad, 36 thermionic heat pipe modules (THPMs) which produce electricity within the reactor and remove waste heat, radiation shielding, waste heat radiators, and reactivity control systems. The use of non-vented fuel elements for short lifetime missions (under five years) will be described

Considerable hazards to be expected by nuclear power

International Nuclear Information System (INIS)

Mueller, H.

1980-01-01

The author examines the military aspects of Pu production. As reactor-Pu is applicable for nuclear weapons the civil utilization of nuclear power provides plutonium concentrations apt for military use for the goverments when closing the fuel cycle by commercial fuel reprocessing. Whether the last threshold shall be trespassed shall depend on how the political intentions of the authorities cooperate with the developments in the international area. After having illustrated the effects on the most important formations of the conflict the author concludes that a radical - utopian - solution alone can grant safety: If the whole fuel cycle is internationalized and controlled by an international authority supported by power of police. In fact, it must be expected that diplomatic and institutional solutions shall have a slower development than political risks. (HSCH) [de

Haemorrhage from the injured extremity is a significant cause of preventable death in military settings. This study evaluated the effect of training on the efficacy of the combat application tourniquet (CAT) and to define standards for military personnel. Participants from a training tank battalion were randomised. Data collected included age, body mass index, mean arterial pressure, hand dominance, femoral artery diameter and skin thickness. The study involved tourniquet application times (AT) and application success rates in basic, after-training and eyes-closed phases. Doppler ultrasound was used to identify the presence or absence of popliteal, radial and ulnar artery pulses. A total of 102 trainees participated. In the after-training phase, the left and right upper extremity ATs were 35 ± 13.1 s, and 34.8 ± 13.5 s and the right and left lower extremity ATs were 20.6 ± 6.0 s and 20.5 ± 5.5 s, respectively. The overall tourniquet success rates in three successive study phases were 69.6%, 82.4% and 91.2%, respectively. A negative significant relationship was found between extremity circumference and tourniquet success. The results show that the efficacy of CAT application increases with training. Further studies are required to investigate the reasons underlying application failures. This single group prospective randomised study involves level of evidence 4.

Polhamus, E. C.

1983-01-01

A review is provided of aerodynamic research conducted at the Langley Research Center with respect to the application of slender wing benefits in the design of high-speed military aircraft, taking into account the supersonic performance and leading-edge vortex flow associated with very highly sweptback wings. The beginning of the development of modern classical swept wing jet aircraft is related to the German Me 262 project during World War II. In the U.S., a theoretical study conducted by Jones (1945) pointed out the advantages of the sweptback wing concept. Developments with respect to variable sweep wings are discussed, taking into account early research in 1946, a joint program of the U.S. with the United Kingdom, the tactical aircraft concept, and the important part which the Langley variable-sweep research program played in the development of the F-111, F-14, and B-1. Attention is also given to hybrid wings, vortex flow theory development, and examples of flow design technology.

A thermoelectric generator (TEG) module and photovoltaic cell (PV) were utilized to harvest energy from temperature gradients of heat sources from ambient heat and light of sun. The output of TEG and PV were connected to a power management circuit consist of step-up dc-dc converter in order to increase the output voltage to supply a low power application such as wireless communication module and the photovoltaic cell for charging an energy storage element in order to switch on a fan for cooling system of the thermoelectric generator. A switch is used as a selector to choose the input of source either from photovoltaic cell or thermoelectric generator to switch on DC-DC step-up converter. In order to turn on the DC-DC step-up converter, the input must be greater than 3V. The energy harvesting was designed so that it can be used continuously and portable anywhere. Multiple sources used in this energy harvesting system is to ensure the system can work in whatever condition either in good weather or not good condition of weather. This energy harvesting system has the potential to be used in military operation and environment that require sustainability of energy resources.

MILITARY MISSION COMBAT EFFICIENCY ESTIMATION SYSTEM

Full Text Available Military infantry recruits, although trained, lacks experience in real-time combat operations, despite the combat simulations training. Therefore, the choice of including them in military operations is a thorough and careful process. This has left top military commanders with the tough task of deciding, the best blend of inexperienced and experienced infantry soldiers, for any military operation, based on available information on enemy strength and capability. This research project delves into the design of a mission combat efficiency estimator (MCEE. It is a decision support system that aids top military commanders in estimating the best combination of soldiers suitable for different military operations, based on available information on enemy’s combat experience. Hence, its advantages consist of reducing casualties and other risks that compromises the entire operation overall success, and also boosting the morals of soldiers in an operation, with such information as an estimation of combat efficiency of their enemies. The system was developed using Microsoft Asp.Net and Sql server backend. A case study test conducted with the MECEE system, reveals clearly that the MECEE system is an efficient tool for military mission planning in terms of team selection. Hence, when the MECEE system is fully deployed it will aid military commanders in the task of decision making on team members’ combination for any given operation based on enemy personnel information that is well known beforehand. Further work on the MECEE will be undertaken to explore fire power types and impact in mission combat efficiency estimation.

Serbia's Military Neutrality: Origins, effects and challenges

Directory of Open Access Journals (Sweden)

Ejdus Filip

2014-10-01

Full Text Available Serbia is the only state in the Western Balkans that is not seeking NATO membership. In December 2007, Serbia declared military neutrality and in spite of its EU membership aspirations, developed very close relations with Moscow. The objective of this paper is threefold. First, I argue that in order to understand why Serbia declared military neutrality, one has to look both at the discursive terrain and domestic power struggles. The key narrative that was strategically used by mnemonic entrepreneurs, most importantly by the former Prime Minister Vojislav Koštunica, to legitimize military neutrality was the trauma of NATO intervention in 1999 and the ensuing secession of Kosovo. In the second part of the paper, I discuss the operational consequences of the military neutrality policy for Serbia's relations with NATO and Russia, as well as for military reform and EU accession. Finally, I spell out the challenges ahead in Serbia's neutrality policy and argue that its decision makers will increasingly be caught between pragmatic foreign policy requirements on the one hand and deeply entrenched traumatic memories on the other.

Secure Multi-party Computation Protocol for Defense Applications in Military Operations Using Virtual Cryptography

Science.gov (United States)

Pathak, Rohit; Joshi, Satyadhar

With the advent into the 20th century whole world has been facing the common dilemma of Terrorism. The suicide attacks on US twin towers 11 Sept. 2001, Train bombings in Madrid Spain 11 Mar. 2004, London bombings 7 Jul. 2005 and Mumbai attack 26 Nov. 2008 were some of the most disturbing, destructive and evil acts by terrorists in the last decade which has clearly shown their evil intent that they can go to any extent to accomplish their goals. Many terrorist organizations such as al Quaida, Harakat ul-Mujahidin, Hezbollah, Jaish-e-Mohammed, Lashkar-e-Toiba, etc. are carrying out training camps and terrorist operations which are accompanied with latest technology and high tech arsenal. To counter such terrorism our military is in need of advanced defense technology. One of the major issues of concern is secure communication. It has to be made sure that communication between different military forces is secure so that critical information is not leaked to the adversary. Military forces need secure communication to shield their confidential data from terrorist forces. Leakage of concerned data can prove hazardous, thus preservation and security is of prime importance. There may be a need to perform computations that require data from many military forces, but in some cases the associated forces would not want to reveal their data to other forces. In such situations Secure Multi-party Computations find their application. In this paper, we propose a new highly scalable Secure Multi-party Computation (SMC) protocol and algorithm for Defense applications which can be used to perform computation on encrypted data. Every party encrypts their data in accordance with a particular scheme. This encrypted data is distributed among some created virtual parties. These Virtual parties send their data to the TTP through an Anonymizer layer. TTP performs computation on encrypted data and announces the result. As the data sent was encrypted its actual value can’t be known by TTP

Full Text Available Cordyceps (Cordyceps militaris exhibits many biological activities including antioxidant, inhibition of inflammation, cancer prevention, hypoglycemic, and antiaging properties, etc. However, a majority of studies involving C. militaris have focused only on in vitro and animal models, and there is a lack of direct translation and application of study results to clinical practice (e.g., health benefits. In this study, we investigated the regulatory effects of C. militaris micron powder (3 doses on the human immune system. The study results showed that administration of C. militaris at various dosages reduced the activity of cytokines such as eotaxin, fibroblast growth factor-2, GRO, and monocyte chemoattractant protein-1. In addition, there was a significant decrease in the activity of various cytokines, including GRO, sCD40L, and tumor necrosis factor-α, and a significant downregulation of interleukin-12(p70, interferon-γ inducible protein 10, and macrophage inflammatory protein-1β activities, indicating that C. militaris at all three dosages downregulated the activity of cytokines, especially inflammatory cytokines and chemokines. Different dosages of C. militaris produced different changes in cytokines.

Fuel cell/electrochemical capacitor hybrid for intermittent high power applications

Energy Technology Data Exchange (ETDEWEB)

Jarvis, L P; Atwater, T B; Cygan, P J [Army Communications-Electronics Command (CECOM), Fort Monmouth, NJ (United States). Research and Development Center

1999-05-01

A hybrid power source was demonstrated to successfully power a simulated power load encountered in portable military electronics and communications equipment. The hybrid system consisted of a 25 W proton exchange membrane fuel cell (PEMFC) stack connected in parallel with a 70 F capacitor bank. The cyclic regime of 18.0 W for 2 min followed by 2.5 W for 18 min was chosen as the baseline for the simulation of power load. The operating potential cut-off voltage for pass/failure was set to 3.0 V. At room temperature (23-25 C), the PEMFC alone could not handle the described baseline regime with the PEMFC operating potential dropping below the cut-off voltage within 10 s. The hybrid, however, continuously powered the same regime for 25 h. Its operating potential never reached the voltage cut-off point, not even during the high load of 18.0 W. The tests with hybrid configuration were aborted after 25 h of operation with no signs of output degradation, suggesting that further extended operation was possible. (orig.)

Modular Power Converters for PV Applications

Energy Technology Data Exchange (ETDEWEB)

Ozpineci, Burak [ORNL; Tolbert, Leon M [ORNL

2012-05-01

This report describes technical opportunities to serve as parts of a technological roadmap for Shoals Technologies Group in power electronics for PV applications. There are many different power converter circuits that can be used for solar inverter applications. The present applications do not take advantage of the potential for using common modules. We envision that the development of a power electronics module could enable higher reliability by being durable and flexible. Modules would have fault current limiting features and detection circuits such that they can limit the current through the module from external faults and can identify and isolate internal faults such that the remaining modules can continue to operate with only minimal disturbance to the utility or customer. Development of a reliable, efficient, low-cost, power electronics module will be a key enabling technology for harnessing more power from solar panels and enable plug and play operation. Power electronics for computer power supplies, communication equipment, and transportation have all targeted reliability and modularity as key requirements and have begun concerted efforts to replace monolithic components with collections of common smart modules. This is happening on several levels including (1) device level with intelligent control, (2) functional module level, and (3) system module. This same effort is needed in power electronics for solar applications. Development of modular units will result in standard power electronic converters that will have a lower installed and operating cost for the overall system. These units will lead to increased adaptability and flexibility of solar inverters. Incorporating autonomous fault current limiting and reconfiguration capabilities into the modules and having redundant modules will lead to a durable converter that can withstand the rigors of solar power generation for more than 30 years. Our vision for the technology roadmap is that there is no need

2016-06-01

Full Text Available The article analyses the development of the military dimension of Russia's economy over the past decade or more, including the significant growth of military expenditure and its principal driver, spending on the ambitious state armament programme to 2020. For the first time for almost twenty-five years Russia once again possesses capable armed forces. With greater economic and military strength Russia's leadership now feels able to be more assertive, even militant, on the world stage. These developments threaten to be constrained by the poor performance of the economy, facing the government with a policy challenge. However, for Russia and the main Western powers there can be no going back to the status quo ante.

DEER-1 and DEER-2 use 20% enriched fuel, and operate for years per fuel loading. The reactor modules and separate steam turbine-generator modules are integrated at the operating site. Turbine inlet conditions are saturated steam at 1000 psi. If only air cooling is available at the operating site, turbine exhaust pressure is 15 psi, with a thermal cycle efficiency of 25%. If water cooling is available, turbine exhaust pressure is 2 psi, with a cycle efficiency of 30%. Various DEER applications are discussed, including secure power for U.S. domestic military bases; power for remote locations, e.g., Alaska, islands, etc.; humanitarian relief in areas affected by hurricanes, tsunamis and earthquakes; undeveloped nations; and micro-grids in large metropolitan areas, including co-generation for applications for district heating and industrial process heat. The technology issues and development requirement for the DEER systems are also discussed. They use existing commercial nuclear fuel, and there is extensive operational experience with reactors based on them. Development of the specific DEER reactors where they differ from previous experience will be required. (authors)

1988-01-01

This paper is concerned with the applications of expert systems to complex military problems. A brief description of needs for expert systems in the military arena is given. A short tutorial on some of the elements of an expert system is found in Appendix I. An important aspect of expert systems concerns using uncertain information and ill-defined procedures. Many of the general techniques of dealing with uncertainty are described in Appendix II. These techniques include Bayesian certainty factors, Dempster-Shafer theory of uncertainty, and Zadeh's fuzzy set theory. The major portion of the paper addresses specific expert system examples such as resource allocation, identification of radar images, maintenance and troubleshooting of electronic equipment, and the interpretation and understanding of radar images. Extensions of expert systems to incorporate learning are examined in the context of military intelligence to determine the disposition, location, and intention of the adversary. The final application involves the use of distributed communicating cooperating expert systems for battle management. Finally, the future of expert systems and their evolving capabilities are discussed

CIVIL-MILITARY RELATIONS IN MUSLIM COUNTRIES. THE CASES OF EGYPT, PAKISTAN, AND TURKEY

Directory of Open Access Journals (Sweden)

Thomas C. BRUNEAU

2013-10-01

Full Text Available This article analyzes the role of the military in the contemporary politics of Egypt, Pakistan, and Turkey. While there is literature on military coups, and analyses of the military in democratic consolidation, there is little on the military’s role in democratic transitions. There is virtually none on Arab or Muslim countries. The Arab Spring has brought renewed attention to the role of the military in these problematic transitions. Utilizing a common framework, based on Alfred Stepan’s “prerogatives”, the article compares and contrasts the position of the military in these three countries. In order to explain the different powers of the militaries in accord with these variables, the article then examines a series of five commonly identified factors promoting or impeding the political role position of the military.

Mobile software application has become a part of today’s lifestyle. This mobile app is designed to help society to be physically active. The application is named UPNM Cardio Fitness, and is developed on the Android platform. The original purpose of the application is to measure and analyse the level of cardiovascular fitness of 18 years old male Military cadet Officers through a 2.4 km run test. The application is based on a data base using Google Fusion Table that stores and analyses the data received. The application consists of two parts: information of the individual and their respective fitness norms that can be accessed either automatically or manually. The classification of the norms is obtained from the fitness norms of 120 male cadets aged 18 years old. The norms are grouped into five categories which are: Excellent, Very Good, Good, Moderate and Poor. The software consists of 5 hyperlinks which are the main page, individual information, test result, file and record. The application is created using MIT App Inventor Software and Windows 7. The creation of the application has enabled researchers particularly in the Science Training programme in UPNM to carry out tests as well as to identify the level of fitness of their trainees immediately, accurately, and systematically.

A compact, low power reactor is being designed to provide electric power for remote, unattended applications. Because of the high fuel and maintenance costs for conventional power sources such as diesel generators, a reactor power supply appears especially attractive for remote and inaccessible locations. Operating at a thermal power level of 135 kWt, the power supply achieves a gross electrical output of 25 kWe from an organic Rankine cycle (ORC) engine. By intentional selection of design features stressing inherent safety, operation in an unattended mode is possible with minimal risk to the environment. Reliability is achieved through the use of components representing existing, proven technology. Low enrichment uranium particle fuel, in graphite core blocks, cooled by heat pipes coupled to an ORC converter insures long-term, virtually maintenance free, operation of this reactor for remote applications. 10 refs., 7 figs., 3 tabs

Sarma, Kalluri R.; Roush, Jerry; Chanley, Charles

2012-06-01

While initial AM OLED products have been introduced in the market about a decade ago, truly successful commercialization of OLEDs has started only a couple of years ago, by Samsung Mobile Display (SMD), with small high performance displays for smart phone applications. This success by Samsung has catalyzed significant interest in AM OLED technology advancement and commercialization by other display manufacturers. Currently, significant manufacturing capacity for AM OLED displays is being established by the industry to serve the growing demand for these displays. The current development in the AM OLED industry are now focused on the development and commercialization of medium size (~10") AM OLED panels for Tablet PC applications and large size (~55") panels for TV applications. This significant progress in commercialization of AM OLED technology is enabled by major advances in various enabling technologies that include TFT backplanes, OLED materials and device structures and manufacturing know-how. In this paper we will discuss these recent advances, particularly as they relate to supporting high performance applications such as aerospace and military systems, and then discuss the results of the OLED testing for aerospace applications.

Intercultural Interactions in a Military Context

Full Text Available The article focuses on the impact of various factors on the process of communication between military specialists and with the local civilians during peace support operations. The importance of religion, national and ethnic identities, military subculture, social status, and personal characteristics for achieving success or failure in interactions is underlined. Some differences between civil culture and military culture are disclosed and the need for cultural knowledge of the military members is stressed. The study is based on presenting and analysing situations of current intercultural interactions in Afghanistan, which deal with various problems that could be encountered by servicemen on a daily basis, i.e. body language differences, expression of friendly, unfriendly or indifferent attitude, typical reactions to gestures, common everyday topics for informal chats. Although the cultural interactions take place in present-day Afghanistan, the conclusions and suggestions are applicable to a much wider context of interacting between people with different cultural background.

U.S. military enlisted accession mental health screening: history and current practice.

Science.gov (United States)

Cardona, Robert Andrew; Ritchie, Elspeth Cameron

2007-01-01

Through the stimulus of war and concerns about neuropsychiatric disability, the U.S. military developed methods to rapidly screen the mental health of World War I and II draftees. Intelligence testing and brief psychiatric screening expanded the accession physical examination and underwent revision to identify only gross mental health disability. Supplemental psychiatric evaluations and written psychological screening tools were abandoned after postwar assessments; they demonstrated poor predictive power in evaluating recruit service capacity for combat environments. Currently, only three mental health accession tools are used to screen applicants before their entrance into military service, namely, educational achievement, cognitive testing, and a cursory psychiatric evaluation. The Navy and Air Force use a fourth screening measure during entry-level training. Educational attainment with high school graduation has been the strongest predictor of finishing a service term. The purpose of this article is to provide both a historical review and a review of testing efforts.

Cordyceps (Cordyceps militaris) exhibits many biological activities including antioxidant, inhibition of inflammation, cancer prevention, hypoglycemic, and antiaging properties, etc. However, a majority of studies involving C. militaris have focused only on in vitro and animal models, and there is a lack of direct translation and application of study results to clinical practice (e.g., health benefits). In this study, we investigated the regulatory effects of C. militaris micron powder (3 doses) on the human immune system. The study results showed that administration of C. militaris at various dosages reduced the activity of cytokines such as eotaxin, fibroblast growth factor-2, GRO, and monocyte chemoattractant protein-1. In addition, there was a significant decrease in the activity of various cytokines, including GRO, sCD40L, and tumor necrosis factor-α, and a significant downregulation of interleukin-12(p70), interferon-γ inducible protein 10, and macrophage inflammatory protein-1β activities, indicating that C. militaris at all three dosages downregulated the activity of cytokines, especially inflammatory cytokines and chemokines. Different dosages of C. militaris produced different changes in cytokines. Copyright © 2014. Published by Elsevier B.V.

An improvement of the applicability of human factors guidelines for coping with human factors issues in nuclear power plants

International Nuclear Information System (INIS)

Lee, Y. H.; Lee, J. Y.

2003-01-01

Human factors have been well known as one of the key factors to the system effectiveness as well as the efficiency and safety of nuclear power plants(NPPs). Human factors engineering(HFE) are included in periodic safety review(PSR) on the existing NPPs and the formal safety assessment for the new ones. However, HFE for NPPs is still neither popular in practice nor concrete in methodology. Especially, the human factors guidelines, which are the most frequent form of human factors engineering in practice, reveal the limitations in their applications. We discuss the limitations and their casual factors found in human factors guidelines in order to lesson the workload of HFE practitioners and to improve the applicability of human factors guidelines. According to the purposes and the phases of HFE for NPPs, more selective items and specified criteria should be prepared carefully in the human factors guidelines for the each HFE applications in practice. These finding on the human factors guidelines can be transferred to the other HFE application field, such as military, aviation, telecommunication, HCI, and product safety

From initial application to routine operation: Reviewing the Applications for Power Uprates

International Nuclear Information System (INIS)

Garis, Ninos; Skaanberg, Lars

2007-01-01

Current plans for power uprates in Swedish nuclear power plants will lead to significant increases in seven units and a lesser increase in one unit. To date SKI has received six applications, and two more are due in 2007. A power uprate process is initiated by the application to the Government by a licensee for approval to increase the thermal output of a reactor unit. This request is addressed to the Government and is forwarded to SKI for a preliminary safety review. The result of the review is then provided by SKI as a basis for a governmental decision. Six applications have been taken through the first stage of the process; of these, three have received governmental approval and three are currently awaiting a decision. If the licensee's application is approved by the Government, deeper analyses and studies are required in order to modify the plant and update the safety analysis report and the associated technical specifications. SKI reviews this material on a continuous basis prior to test and routine operation at the increased power level. There are four stages that require attention and review by SKI; 1. Review of the application to the Government for approval to operate at increased power levels, and preparation of a suitable answer. 2. Review and approval of the preliminary safety analysis report (PSAR) 3. Review and approval of the application for testing at the higher power level 4. Review and approval of routine operation at the higher power level. A thorough description of the handling of a power uprate process can be found in the SKI PM (SKI-PM 04:11) that is available on the SKI website (in Swedish)

Long life, low cost, rechargeable AgZn battery for non-military applications

Science.gov (United States)

Brown, Curtis C.

1996-03-01

Of the rechargeable (secondary) battery systems with mature technology, the silver oxide-zinc system (AgZn) safely offers the highest power and energy (watts and watt hours) per unit of volume and mass. As a result they have long been used for aerospace and defense applications where they have also proven their high reliability. In the past, the expense associated with the cost of silver and the resulting low production volume have limited their commercial application. However, the relative low cost of silver now make this system feasible in many applications where high energy and reliability are required. One area of commercial potential is power for a new generation of sophisticated, portable medical equipment. AgZn batteries have recently proven ``enabling technology'' for power critical, advanced medical devices. By extending the cycle calendar life to the system (offers both improved performance and lower operating cost), a combination is achieved which may enable a wide range of future electrical devices. Other areas where AgZn batteries have been used in nonmilitary applications to provide power to aid in the development of commercial equipment have been: (a) Electrically powered vehicles; (b) Remote sensing in nuclear facilities; (c) Special effects equipment for movies; (d) Remote sensing in petroleum pipe lines; (e) Portable computers; (f) Fly by wire systems for commercial aircraft; and (g) Robotics. However none of these applications have progressed to the level where the volume required will significantly lower cost.

High power infrared QCLs: advances and applications

Science.gov (United States)

Patel, C. Kumar N.

2012-01-01

QCLs are becoming the most important sources of laser radiation in the midwave infrared (MWIR) and longwave infrared (LWIR) regions because of their size, weight, power and reliability advantages over other laser sources in the same spectral regions. The availability of multiwatt RT operation QCLs from 3.5 μm to >16 μm with wall plug efficiency of 10% or higher is hastening the replacement of traditional sources such as OPOs and OPSELs in many applications. QCLs can replace CO2 lasers in many low power applications. Of the two leading groups in improvements in QCL performance, Pranalytica is the commercial organization that has been supplying the highest performance QCLs to various customers for over four year. Using a new QCL design concept, the non-resonant extraction [1], we have achieved CW/RT power of >4.7 W and WPE of >17% in the 4.4 μm - 5.0 μm region. In the LWIR region, we have recently demonstrated QCLs with CW/RT power exceeding 1 W with WPE of nearly 10 % in the 7.0 μm-10.0 μm region. In general, the high power CW/RT operation requires use of TECs to maintain QCLs at appropriate operating temperatures. However, TECs consume additional electrical power, which is not desirable for handheld, battery-operated applications, where system power conversion efficiency is more important than just the QCL chip level power conversion efficiency. In high duty cycle pulsed (quasi-CW) mode, the QCLs can be operated without TECs and have produced nearly the same average power as that available in CW mode with TECs. Multiwatt average powers are obtained even in ambient T>70°C, with true efficiency of electrical power-to-optical power conversion being above 10%. Because of the availability of QCLs with multiwatt power outputs and wavelength range covering a spectral region from ~3.5 μm to >16 μm, the QCLs have found instantaneous acceptance for insertion into multitude of defense and homeland security applications, including laser sources for infrared

Pulse power 350 V nickel-metal hydride battery power-D-005-00181

Eskra, Michael D.; Ralston, Paula; Salkind, Alvin; Plivelich, Robert F.

Energy-storage devices are needed for applications requiring very high-power over short periods of time. Such devices have various military (rail guns, electromagnetic launchers, and DEW) and commercial applications, such as hybrid electric vehicles, vehicle starting (SLI), and utility peak shaving. The storage and delivery of high levels of burst power can be achieved with a capacitor, flywheel, or rechargeable battery. In order to reduce the weight and volume of many systems they must contain advanced state-of-the-art electrochemical or electromechanical power sources. There is an opportunity and a need to develop energy-storage devices that have improved high-power characteristics compared to existing ultra capacitors, flywheels or rechargeable batteries. Electro Energy, Inc. has been engaged in the development of bipolar nickel-metal hydride batteries, which may fulfil the requirements of some of these applications. This paper describes a module rated at 300 V (255 cells) (6 Ah). The volume of the module is 23 L and the mass is 56 kg. The module is designed to deliver 50 kW pulses of 10 s duration at 50% state-of-charge. Details of the mechanical design of the module, safety considerations, along with the results of initial electrical characterization testing by the customer will be discussed. Some discussion of the possibilities for design optimization is also included.

Factors underlying a possible excess of amyotrophic lateral sclerosis (ALS) among military veterans remain unidentified. Limitations of previous studies on this topic include reliance on ALS mortality as a surrogate for ALS incidence, low statistical power, and sparse information on military-related factors. We evaluated associations between military-related factors and ALS using data from a case-control study of U.S. military veterans. From 2005 to 2010, we identified medical record-confirmed ALS cases via the National Registry of Veterans with ALS and controls via the Veterans Benefits Administration's Beneficiary Identification and Records Locator System database. In total, we enrolled 621 cases and 958 frequency-matched controls in the Genes and Environmental Exposures in Veterans with Amyotrophic Lateral Sclerosis study. We collected information on military service and deployments and 39 related exposures. We used unconditional logistic regression models to estimate odds ratios (ORs) and 95% confidence intervals (CIs). We used inverse probability weighting to adjust for potential bias from confounding, missing covariate data, and selection arising from a case group that disproportionately included long-term survivors and a control group that may or may not differ from U.S. military veterans at large. The odds of ALS did not differ for veterans of the Air Force, Army, Marines, and Navy. We found higher odds of ALS for veterans whose longest deployment was World War II or the Korean War and a positive trend with total years of all deployments (OR=1.27; 95% CI: 1.06, 1.52). ALS was positively associated with exposure to herbicides for military purposes, nasopharyngeal radium, personal pesticides, exhaust from heaters or generators, high-intensity radar waves, contaminated food, explosions within one mile, herbicides in the field, mixing and application of burning agents, burning agents in the field, and Agent Orange in the field, with ORs between 1.50 and 7

2013-01-01

We have developed III–V-based high-efficiency laser power converters (LPCs), optimized specifically for converting monochromatic laser radiation at the eye-safe wavelength of 1.55 µm into electrical power. The applications of these photovoltaic cells include high-efficiency space-based and terrestrial laser power transfer and subsequent conversion to electrical power. In addition, these cells also find use in fibre-optic power delivery, remote powering of subcutaneous equipment and several other optical power delivery applications. The LPC design is based on lattice-matched InGaAsP/InP and incorporates elements for photon-recycling and contact design for efficient carrier extraction. Here we compare results from electro-optical design simulations with experimental results from prototype devices studied both in the lab and in field tests. We analyse wavelength and temperature dependence of the LPC characteristics. An experimental conversion efficiency of 44.6% [±1%] is obtained from the prototype devices under monochromatic illumination at 1.55 µm (illumination power density of 1 kW m −2 ) at room temperature. Further design optimization of our LPC is expected to scale the efficiency beyond 50% at 1 kW m −2 . (paper)

The SP-100 program was established in 1983 by DOD, DOE, and NASA as a joint program to develop the technology necessary for space nuclear power systems for military and civil application. During FY-86 and 87, the NASA SP-100 Advanced Technology Program was devised to maintain the momentum of promising technology advancement efforts started during Phase 1 of SP-100 and to strengthen, in key areas, the chances for successful development and growth capability of space nuclear reactor power systems for future space applications. In FY-88, the Advanced Technology Program was incorporated into NASA's new Civil Space Technology Initiative (CSTI). The CSTI Program was established to provide the foundation for technology development in automation and robotics, information, propulsion, and power. The CSTI High Capacity Power Program builds on the technology efforts of the SP-100 program, incorporates the previous NASA SP-100 Advanced Technology project, and provides a bridge to NASA Project Pathfinder. The elements of CSTI High Capacity Power development include Conversion Systems, Thermal Management, Power Management, System Diagnostics, and Environmental Interactions. Technology advancement in all areas, including materials, is required to assure the high reliability and 7 to 10 year lifetime demanded for future space nuclear power systems. The overall program will develop and demonstrate the technology base required to provide a wide range of modular power systems as well as allowing mission independence from solar and orbital attitude requirements. Several recent advancements in CSTI High Capacity power development will be discussed

2016-11-01

Despite efforts to increase patient safety, hundreds of thousands of lives are lost each year to preventable health care errors. The Institute of Medicine and other organizations have recommended that facilitating effective interprofessional health care team work can help address this problem. While the concept of interprofessional health care teams is known, understanding and organizing effective team performance have proven to be elusive goals. Although considerable research has been conducted in the civilian sector, scholars have yet to extend research to the military context. Indeed, delivering the highest caliber of health care to our service men and women is vitally important. This commentary describes a new initiative as the Uniformed Services University of the Health Sciences aimed at researching the characteristics of successful military interprofessional teams and why those characteristics are important. It also describes the interprofessional education initiative that Uniformed Services University is launching to help optimize U.S. military health care.

LaPointe, Michael R.; Sankovic, John M.

2000-01-01

Interest in megawatt-class electromagnetic propulsion has been rekindled to support newly proposed high power orbit transfer and deep space mission applications. Electromagnetic thrusters can effectively process megawatts of power to provide a range of specific impulse values to meet diverse in-space propulsion requirements. Potential applications include orbit raising for the proposed multi-megawatt Space Solar Power Satellite and other large commercial and military space platforms, lunar and interplanetary cargo missions in support of the NASA Human Exploration and Development of Space strategic enterprise, robotic deep space exploration missions, and near-term interstellar precursor missions. As NASA's lead center for electric propulsion, the Glenn Research Center is developing a number of high power electromagnetic propulsion technologies to support these future mission applications. Program activities include research on MW-class magnetoplasmadynamic thrusters, high power pulsed inductive thrusters, and innovative electrodeless plasma thruster concepts. Program goals are highlighted, the status of each research area is discussed, and plans are outlined for the continued development of efficient, robust high power electromagnetic thrusters

Industrial Applications of High Power Ultrasonics

Science.gov (United States)

Patist, Alex; Bates, Darren

Since the change of the millennium, high-power ultrasound has become an alternative food processing technology applicable to large-scale commercial applications such as emulsification, homogenization, extraction, crystallization, dewatering, low-temperature pasteurization, degassing, defoaming, activation and inactivation of enzymes, particle size reduction, extrusion, and viscosity alteration. This new focus can be attributed to significant improvements in equipment design and efficiency during the late 1990 s. Like most innovative food processing technologies, high-power ultrasonics is not an off-the-shelf technology, and thus requires careful development and scale-up for each and every application. The objective of this chapter is to present examples of ultrasonic applications that have been successful at the commercialization stage, advantages, and limitations, as well as key learnings from scaling up an innovative food technology in general.

Science.gov (United States)

Süleyman, Sarıkürk; Volkan, Karaca; İbrahim, Kocaman; Ahmet, Şirzai

2012-05-01

Cloud computing is known as a novel information technology (IT) concept, which involves facilitated and rapid access to networks, servers, data saving media, applications and services via Internet with minimum hardware requirements. Use of information systems and technologies at the battlefield is not new. Information superiority is a force multiplier and is crucial to mission success. Recent advances in information systems and technologies provide new means to decision makers and users in order to gain information superiority. These developments in information technologies lead to a new term, which is known as network centric capability. Similar to network centric capable systems, cloud computing systems are operational today. In the near future extensive use of military clouds at the battlefield is predicted. Integrating cloud computing logic to network centric applications will increase the flexibility, cost-effectiveness, efficiency and accessibility of network-centric capabilities. In this paper, cloud computing and network centric capability concepts are defined. Some commercial cloud computing products and applications are mentioned. Network centric capable applications are covered. Cloud computing supported battlefield applications are analyzed. The effects of cloud computing systems on network centric capability and on the information domain in future warfare are discussed. Battlefield opportunities and novelties which might be introduced to network centric capability by cloud computing systems are researched. The role of military clouds in future warfare is proposed in this paper. It was concluded that military clouds will be indispensible components of the future battlefield. Military clouds have the potential of improving network centric capabilities, increasing situational awareness at the battlefield and facilitating the settlement of information superiority.

1997-03-01

This report describes a Strategic Environmental Research and Development Program (SERDP) project to field a dish/Stirling system at a southwestern US military facility. This project entitled ``Dish/Stirling for DoD Applications`` was started in August 1993 and was completed in September 1996. The project`s objective was to assist military facilities to field and evaluate emerging environmentally sound and potentially economical dish/Stirling technology. Dish/Stirling technology has the potential to produce electricity at competitive costs while at the same time providing a secure and environmentally benign source of power. In accordance with the SERDP charter, this project leveraged a US Department of Energy (DOE) cost-shared project between Sandia National Laboratories and Cummins Power Generation, Inc. (CPG). CPG is a wholly owned subsidiary of Cummins Engine Company, a leading manufacturer of diesel engines. To accomplish this objective, the project called for the installation of a dish/Stirling system at a military facility to establish first-hand experience in the operation of a dish/Stirling system. To scope the potential DoD market for dish/Stirling technology and to identify the site for the demonstration, a survey of southwestern US military facilities was also conducted. This report describes the project history, the Cummins dish/Stirling system, results from the military market survey, and the field test results.

Photovoltaic power plants operates currently maximal power point tracking (MPPT). For microgrid applications, however, a PV power plant can not operate in the MPPT mode in all conditions. When a microgrid is islanded from the grid with few loads, a limitation of the produced power by PV plants is required and prescribed by the Distribution System Operator. This paper proposes a power control technique integrated into a dynamic model of a PV power plant by using equivalent continuous models of power electronic converters. The power limitation mode of the PV is performed by applying the correct PV terminal voltage, which corresponds to the prescribed power reference. The proposed global model is validated by simulations with the help of Matlab-Simulink trademark. (orig.)

International collaborations about fuel studies for reactor recycling of military quality plutonium

International Nuclear Information System (INIS)

Bernard, H.; Chaudat, J.P.

1997-01-01

In November 1992, an agreement was signed between the French and Russian governments to use in Russia and for pacific purposes the plutonium recovered from the Russian nuclear weapons dismantling. This plutonium will be transformed into mixed oxide fuels (MOX) for nuclear power production. The French Direction of Military Applications (DAM) of the CEA is the operator of the French-Russian AIDA program. The CEA Direction of Fuel Cycle (DCC) and Direction of Nuclear Reactors (DRN) are involved in the transformation of metallic plutonium into sinterable oxide powder for MOX fuel manufacturing. The Russian TOMOX (Treatment of MOX powder Metallic Objects) and DEMOX (MOX Demonstration) plants will produce the MOX fuel assemblies for the 4 VVER 1000 reactors of Balakovo and the fast BN 600 reactor. The second part of the program will involve the German Siemens and GRS companies for the safety studies of the reactors and fuel cycle plants. The paper gives also a brief analysis of the US policy concerning the military plutonium recycling. (J.S.)

Redefined Soviet military doctrine in perspective

International Nuclear Information System (INIS)

Menning, B.W.

1992-01-01

On May 29, 1987, the Warsaw Pact's Political Consultative Committee issued a communique proclaiming that the military doctrine of the Warsaw Pact member states is strictly defensive and proceeds from the fact that the application of military means to resolve any dispute is inadmissible under current conditions. Following this declaration, a corresponding redefinition of Soviet military doctrine to emphasize defensiveness and war prevention has evoke lively commentary and debate in both the West and the East. Because doctrinal issues are likely to retain significance during arms control and security negotiations. The purpose of this paper is to highlight important trends associated with a continuing dialogue over Soviet military doctrine and to assess what the future portends as doctrinal discussions unfold. Since 1987 the accelerating pace of change has accentuated the importance of doctrinally related concerns. As a result of the INF Treaty and the Stockholm agreement, there has been greater transparency regarding Soviet and Warsaw Pact military developments. On December 7, 1988, General Secretary Mikhail Gorbachev announced unilateral troop reduction over the next two years, which, when completed, would reduce the offensive capabilities of Soviet forces in Eastern Europe. In March 1989 talks on Confidence- and Security-Building Measures (CSBM) opened in Vienna, with suggestions for exchanges of views on military policy. At the very same time, NATO and the Warsaw Pact began formal negotiations on reduction of Conventional Forces in Europe (CFE) with a specific mandate to reduce those asymmetries that most favored prosecution of deep operations

1982-10-01

The objective of EPRI Research Project 1396-1 was to evaluate the applicability and effectiveness of Job Performance Aids (JPAs) in nuclear power plant situations. For over twenty years, JPAs have been developed in military situations to meet the problems of confusing, incomplete, and inaccurate procedures on maintenance jobs. Kinton, Incorporated of Alexandria, Virginia applied the military experience with JPAs to nuclear power plant situations and identified potential benefits in terms of cost reductions and improved performance. Sample JPAs were developed for Control Room Operations, Maintenance, Plant Operations, Instrumentation and Control, Health Physics, and Quality Assurance tasks (procedures) in selected nuclear plants. JPAs were also developed for a prototype condenser tube leak detection system in the design stage, as well as for generic classes of circuit breaker equipment. Based on the results of the study, the use of JPAs is recommended for plant procedures of medium to high difficulty and for those tasks performed infrequently, even if fairly simple

2017-03-01

As part of a Military Emergency Medical Services (EMS) system process improvement initiative, the authors sought to objectively evaluate the U.S. military EMS system for the island of Okinawa. They applied a program evaluation tool currently utilized by the U.S. National Park Service (NPS). A comprehensive needs assessment was conducted to evaluate the current Military EMS system in Okinawa, Japan. The NPS EMS Program Audit Worksheet was used to get an overall "score" of our assessment. After all the data had been collected, a joint committee of Military EMS physicians reviewed the findings and made formal recommendations. From 2011 to 2014, U.S. military EMS on Okinawa averaged 1,345 ± 137 patient transports annually. An advanced life support (ALS) provider would have been dispatched on 558 EMS runs (38%) based on chief complaint in 2014 had they been available. Over 36,000 man-hours were expended during this period to provide National Registry Emergency Medical Technician (EMT)-accredited instruction to certify 141 Navy Corpsman as EMT Basics. The NPS EMS Program Audit Worksheet was used and the program scored a total of 31, suggesting the program is well planned and operating within standards. This evaluation of the Military EMS system on Okinawa using the NPS program assessment and audit worksheet demonstrates the NPS evaluation instruments may offer a useful assessment tool for the evaluation of Military EMS systems.

Abraham, Traci; Cheney, Ann M; Curran, Geoffrey M

2017-09-01

This theoretical treatise uses the scientific literature concerning help seeking for mental illness among those with a background in the U.S. military to posit a more complex definition of military culture. The help-seeking literature is used to illustrate how hegemonic masculinity, when situated in the military field, informs the decision to seek formal treatment for mental illness among those men with a background in the U.S. military. These analyses advocate for a nuanced, multidimensional, and situated definition of U.S. military culture that emphasizes the way in which institutional structures and social relations of power intersect with individual values, beliefs, and motivations to inform and structure health-related practices.

Bore V. Jegdić

2012-01-01

Full Text Available This paper analyzed the conditions for the occurrence of corrosion processes on historically important weapons and military equipment made of steel during the period in outdoor environment. A considerable attention has been given to the characteristics of the most important corrosion products formed on the steel surface. The formation of akaganite, β-FeOOH is a sign of active corrosion under a layer of corrosion products. The conditions that cause the formation and regeneration of hydrochloric and sulphuric acid during the exposure to the elements were analyzed. The most often applied methods of diagnostics and procedures of removing active corrosion anions (desalination were described as well. The NaOH solution of certain pH values still has the most important application for the desalination process. The procedures for cleaning the surface before the application of protective coatings and the application of chemicals that transform rust into stable compounds were discussed. As protective coatings, different types of organic coatings plated on well-prepared steel surfaces were used and sometimes special types of waxes as well. This paper presents the results of the tests of corrosion products taken from the exhibits of weapons and military equipment from the Military Museum in Belgrade.

Cultural evolution of military camouflage.

Science.gov (United States)

Talas, Laszlo; Baddeley, Roland J; Cuthill, Innes C

2017-07-05

While one has evolved and the other been consciously created, animal and military camouflage are expected to show many similar design principles. Using a unique database of calibrated photographs of camouflage uniform patterns, processed using texture and colour analysis methods from computer vision, we show that the parallels with biology are deeper than design for effective concealment. Using two case studies we show that, like many animal colour patterns, military camouflage can serve multiple functions. Following the dissolution of the Warsaw Pact, countries that became more Western-facing in political terms converged on NATO patterns in camouflage texture and colour. Following the break-up of the former Yugoslavia, the resulting states diverged in design, becoming more similar to neighbouring countries than the ancestral design. None of these insights would have been obtained using extant military approaches to camouflage design, which focus solely on concealment. Moreover, our computational techniques for quantifying pattern offer new tools for comparative biologists studying animal coloration.This article is part of the themed issue 'Animal coloration: production, perception, function and application'. © 2017 The Author(s).

Portable power applications of fuel cells

Energy Technology Data Exchange (ETDEWEB)

Weston, M.; Matcham, J.

2002-07-01

This report describes the state-of-the-art of fuel cell technology for portable power applications. The study involved a comprehensive literature review. Proton exchange membrane fuel cells (PEMFCs) have attracted much more interest than either direct methanol fuel cells (DMFCs) or solid oxide fuel cells (SOFCs). However, issues relating to fuel choice and catalyst design remain with PEMFCs; DMFCs have excellent potential provided issues relating to the conducting membrane can be resolved but the current high temperature of operation and low power density currently makes SOFCs less applicable to portable applications. Available products are listed and the obstacles to market penetration are discussed. The main barriers are cost and the size/weight of fuel cells compared with batteries. Another key problem is the lack of a suitable fuel infrastructure.

1994-06-01

Flight instruments have begun to use color active liquid crystal displays (AMLCDs), signaling the beginning of a significant transition from electromechanical and cathode ray tube display designs to AMLCD designs. We have the opportunity with this new technology to establish common products capable of meeting user requirements for sunlight-readable, color and gray scale-capable, high-pixel-count, flat-panel displays for weapon systems. The Wright Laboratory is leading the development of standard and specification documentation for this new generation of display modules based on requirements for U.S. military aircraft. These requirements are similar in many ways to those of both the civil aviation and automotive industries. Accordingly, commonality with these applications is incorporated, where possible, along with the requirements for all military combat applications. Industry and government organizations are involved in this process through workshops and draft review processes. Military procurement specifications for combat system applications may use this information as a source of recommended best practice for this new generation of digital flat panel displays. The draft standard will be revised based upon continuing feedback by early 1995.

Applications of power beaming from space-based nuclear power stations

International Nuclear Information System (INIS)

Powell, J.R.; Botts, T.E.; Hertzberg, A.

1981-01-01

Power beaming from space-based reactor systems is examined using an advanced compact, lightweight Rotating Bed Reactor (RBR). Closed Brayton power conversion efficiencies in the range of 30 to 40% can be achieved with turbines, with reactor exit temperatures on the order of 2000 0 K and a liquid drop radiator to reject heat at temperatures of approx. 500 0 K. Higher RBR coolant temperatures (up to approx. 3000 0 K) are possible, but gains in power conversion efficiency are minimal, due to lower expander efficiency (e.g., a MHD generator). Two power beaming applications are examined - laser beaming to airplanes and microwave beaming to fixed ground receivers. Use of the RBR greatly reduces system weight and cost, as compared to solar power sources. Payback times are a few years at present prices for power and airplane fuel

Tritium power source for long-lived sensors

2014-06-01

A tritium-based indirect converting photovoltaic (PV) power source has been designed and prototyped as a long-lived (~15 years) power source for sensor networks. Tritium is a biologically benign beta emitter and low-cost isotope acquired from commercial vendors for this purpose. The power source combines tritium encapsulated with a radioluminescent phosphor coupled to a commercial PV cell. The tritium, phosphor, and PV components are packaged inside a BA5590-style military-model enclosure. The package has been approved by the nuclear regulatory commission (NRC) for use by DOD. The power source is designed to produce 100μW electrical power for an unattended radiation sensor (scintillator and avalanche photodiode) that can detect a 20 μCi source of 137Cs at three meters. This beta emitting indirect photon conversion design is presented as step towards the development of practical, logistically acceptable, lowcost long-lived compact power sources for unattended sensor applications in battlefield awareness and environmental detection.

Military medical facilities of the Ministry of Defence of the Russian, have received the right to provide additional services and have been involved in the sphere of market relations. The strong influence of market relations - an objective reality that must be used for the development of military medical institutions and improving quality of care.Effective commercial activity can improve capabilities of the military medical institutions. This requires constant study of market mechanisms to implement and develop their competitive advantage. The paper substantiates the need for the participation of military medical institutions in the provision of health services to the public on the terms of compensation incurred by financial institutions costs (paid medical services, medical assistance program of compulsory and voluntary health insurance). Taking into account the specifics of military medical institutions set out basic principles and recommendations have been implementing marketing approach in their management, the practical application of which will not only increase efficiency, but also create conditions to improve the financial and economic indicators. This knowledge will help the mechanism of functioning health care market and the rules of interaction of market counterparties.

2002-01-01

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.

to work over the Internet and represents an open standard maintained by the W3C (the World Wide Web Consortium. The drawback of SOAP is interoperability which is not always 100% practicable with CORBA, ie. the existing implementation does not always meet the required reliability. This may be one of the causes of an insufficient number of available Web services on the Internet. The implementation of SOAP is possible in almost any programming language, on all popular platforms, so it has the potential to create a transparent web of services and applications that can be accessed on demand by everyone from every point, which will lead to the explosive growth of new services and therefore profits. SOAP does not try to replace CORBA or any other distributed system. Compared to CORBA, SOAP is less powerful, but it is impressive in its simplicity and scalability, which is very useful from the aspect of need for a wider acceptance by companies and by developers. SOAP is still developing, and a number of new protocols will appear, simplifying and facilitating the implementation of Web services in all business areas, including military information systems. Conclusion The possibility to connect the existing solutions is of great importance in determining the development strategy of information systems in the Army as well as in other complex organizational systems that contain heterogeneous hardware and software platforms. The research and analysis of the application of these standardized concepts, technologies and development platforms, including the experience of foreign armed forces lead to the conclusion that the concept of development of information systems in the Internet environment by using software components is a recommendation for strategic determination to overcome incompatible and unrelated existing partial software solutions. The basic idea is based on Web services which can be created from finished applications or from the start, while programming languages

Tobacco Pricing in Military Stores: Views of Military Policy Leaders.

Science.gov (United States)

Smith, Elizabeth A; Jahnke, Sara A; Poston, Walker S C; Malone, Ruth E; Haddock, Christopher K

2016-10-01

Higher tobacco taxes reduce tobacco use. On military installations, cigarettes and other tobacco products are sold tax-free, keeping prices artificially low. Pricing regulations in the military specify that tobacco should be within 5% of the local most competitive price, but prices still average almost 13% lower than those at local Walmarts. To gain insight into policy leaders' ideas and positions on military tobacco pricing, we interviewed members of the Department of Defense (DoD) Addictive Substances Misuse Advisory Committee and the Advisory Committee on Tobacco about tobacco pricing policies (n = 12). Participants frequently lacked specific knowledge of details of military pricing policy, and the impact higher prices might have on military tobacco use. Most participants thought tobacco should not be sold at military stores, but many also felt that this policy change was unlikely due to tobacco industry pressure, and DoD reliance on tobacco profits to support Morale, Welfare, and Recreation funds. Achieving a tobacco-free military will require changing pricing policy, but this study suggests that for effective implementation, military leadership must also understand and articulate more clearly the rationale for doing so. Previous work has found that adherence to military tobacco pricing policy is inconsistent at best. This study suggests that lack of knowledge about the policy and conflicting pressures resulting from the funding stream tobacco sales represent extend to high level military policy leaders. Without clearer information and direction, these leaders are unlikely to be able to establish and implement better tobacco pricing policy. © The Author 2016.

One of the major difficulties in military conversion is to find cases that are realistic from the point of view of politics, economics, financing and society. This report proposes an example which is believed to meet the above criteria. The suggestion is to use manpower, and to some extent the installations (laboratories, factories) of Russian military nuclear complex to build a small series of fast neutron plutonium storage reactor power plants. These plants with a unit output of some 800 MWe would have two main functions: store the excess of Russian military grade plutonium and produce electricity at competitive prices

Barrett, M.

1991-01-01

The Modular Accident Analysis Program (MAAP) is a fast running, easy to use code for modeling accidents at nuclear power plants. These attributes make MAAP ideal for a number of applications. At Duke Power Company, MAAP has been used extensively in the performance of probabilistic risk assessment (PRA). Applications have also been found in the areas of emergency preparedness, training, and severe accident management. Specific applications of MAAP are presented in this paper with special attention to examples in the area of PRA success criteria development and severe accident management strategies selection. The application of MAAP to developing success criteria for ECCS performance during a large LOCA is presented. Additionally, an example of how MAAP has been used in the assessment of an alternative feed and bleed strategy is provided

Pseudospark switches (PSS) for pulsed power applications

Heine, F; Prucker, U; Frank, K; Goertler, A; Schwandner, A; Tkotz, R; Hoffmann, D H.H.; Christiansen, J [Univ. of Erlangen (Germany). Physics Dept. I

Based on the pseudospark discharge, a low pressure gas discharge in a special geometry, fast closing switches for different pulsed power applications have been designed. Medium power PSS ({<=} 30 kA peak current) were used in laser circuits whereas high current PSS are tested successfully in high current pulsed power applications ({<=} 200 kA). For currents of a few kA the discharge is supported by cathode spots on the cold cathode surface. For higher currents, anode activity is observed too. Inserting semiconductor material seems not only to suppress high erosive spot formation but to support diffuse large-area electrode emission. A different approach to solving the problem of lowering the erosion rate is the multichannel PSS (MUPS). In order to distribute the discharge current to more than one single channel, three or more discharge channels are radial or coaxial arranged. With regard to high voltage applications the maximum hold-off voltage was increased by adding an intermediate electrode. (author). 1 figs., 12 refs.

Environmental and industrial applications of pulsed power systems

International Nuclear Information System (INIS)

Neau, E.L.

1993-01-01

The technology base formed by the development of high peak power simulators, laser drivers, free electron lasers (FEL's), and Inertial Confinement Fusion (ICF) drivers from the early 60's through the late 80's is being extended to high average power short-pulse machines with the capabilities of performing new roles in environmental cleanup applications and in supporting new types of industrial manufacturing processes. Some of these processes will require very high average beam power levels of hundreds of kilowatts to perhaps megawatts. In this paper we briefly discuss new technology capabilities and then concentrate on specific application areas that may benefit from the high specific energies and high average powers attainable with short-pulse machines

Applications of energy harvesting for ultralow power technology

Science.gov (United States)

Pop-Vadean, A.; Pop, P. P.; Barz, C.; Chiver, O.

2015-06-01

Ultra-low-power (ULP) technology is enabling a wide range of new applications that harvest ambient energy in very small amounts and need little or no maintenance - self-sustaining devices that are capable of perpetual or nearly perpetual operation. These new systems, which are now appearing in industrial and consumer electronics, also promise great changes in medicine and health. Until recently, the idea of micro-scale energy harvesting, and collecting miniscule amounts of ambient energy to power electronic systems, was still limited to research proposals and laboratory experiments.Today an increasing number of systems are appearing that take advantage of light, vibrations and other forms of previously wasted environmental energy for applications where providing line power or maintaining batteries is inconvenient. In the industrial world, where sensors gather information from remote equipment and hazardous processes; in consumer electronics, where mobility and convenience are served; and in medical systems, with unique requirements for prosthetics and non-invasive monitoring, energy harvesting is rapidly expanding into new applications.This paper serves as a survey for applications of energy harvesting for ultra low power technology based on various technical papers available in the public domain.

Physical Training Strategies for Military Women's Performance Optimization in Combat-Centric Occupations.

Science.gov (United States)

Nindl, Bradley C

2015-11-01

The physiological differences, particularly of upper-body strength and power, between women and men, and the rigors of combat-centric occupational demands would seem to place women at a significant disadvantage, as the U.S. military opens up previously closed combat-arms military occupational specialties (MOSs) to women. This inherent disadvantage can be significantly mitigated by implementing effective and comprehensive physical training (PT) regimens for women targeting those fitness components most critical for those tasks considered most essential for solider warfighting duties (i.e., strength and power). Regrettably, the military historical and legacy overemphasis on aerobic fitness and on "field expediency" as the major criteria for implementing training have limited the extent to which the military has fully operationalized state-of-the-science PT policies. This continued legacy approach could be problematic regarding fully enhancing women's abilities to perform physically demanding combat-centric occupations and could place the successful integration of women into ground combat MOSs at significant risk. Seminal studies from the literature indicate that (a) a minimum of 6 months of periodized combined resistance/endurance training preparedness is recommended for untrained women considering entering combat-arms MOS training; (b) any comprehensive PT program should incorporate and emphasize progressive load carriage training; (c) a greater emphasis on upper body on strength/power development in military women is needed; (d) heavy resistance training in the range of 3-8 repetition maximum sets should be incorporated into training programs to target type II motor units and muscle fibers (those fibers that produce the most force and have the greatest capacity to hypertrophy); (e) low-volume, high-intensity interval training should be considered as a time-efficient training method to improve aerobic fitness while protecting against lower-body musculoskeletal

INDUSTRIAL/MILITARY ACTIVITY-INITIATED ACCIDENT SCREENING ANALYSIS

Impacts due to nearby installations and operations were determined in the Preliminary MGDS Hazards Analysis (CRWMS M&O 1996) to be potentially applicable to the proposed repository at Yucca Mountain. This determination was conservatively based on limited knowledge of the potential activities ongoing on or off the Nevada Test Site (NTS). It is intended that the Industrial/Military Activity-Initiated Accident Screening Analysis provided herein will meet the requirements of the ''Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants'' (NRC 1987) in establishing whether this external event can be screened from further consideration or must be included as a design basis event (DBE) in the development of accident scenarios for the Monitored Geologic Repository (MGR). This analysis only considers issues related to preclosure radiological safety. Issues important to waste isolation as related to impact from nearby installations will be covered in the MGR performance assessment.

SELF-DETERMINATION AND POWER: A HUMAN-CENTRIC APPROACH TO THE INTERNATIONAL RELATIONS

Directory of Open Access Journals (Sweden)

Shameer Modongal

2017-05-01

Full Text Available This paper analyzes the importance of self-determination in international relations. It explains the puzzle why some small regions or group of people are ready to be small states by separating from big powerful states. The self-determination of a nation is preferable to the people than a military power of the large state. The military power of a state may not translate into a better life of people. So people’s empowerment cannot be treated the necessary outcome of state’s military power. When one group of people feel as marginalized in national policymaking and its implications, they show a secessionist tendency. This paper contends that people may prefer their ideology, identity and self-determination than the power of the state.

Strategies for Allocation of the US Federal Budget: Military and Innovative Dimension

Full Text Available The aim of the article is to define the conceptual framework and features of priority directions in redistribution of the US federal funds. This subject is very relevant because it discloses a system of financing and allocations of the most powerful state in the world in many aspects. The article describes the structure of government funding of the national military sector and directions of the modernization of the US military-industrial complex. It has been determined that in the global expansion of military actions the USA in no case remain aloof from the given events. Manufacturing the US military products plays a key role in the defense industry not only of the country itself but also the international community as a whole. For Ukraine, with the complications in its military-political situation, the cooperation with the United States and inclusion of the financial assistance to our country in its federal budget are very important. The mentioned directions for allocating the received funds in the amount of $ 300 mln by the Ukrainian government confirm the support by the American state of our military equipment and modernization of the national defense industry

Bringing the Military Back in: Military Expenditures and Economic Growth 1990 to 2003

Directory of Open Access Journals (Sweden)

Jeffrey Kentor

2015-08-01

Full Text Available After the “peace bonus” era, global military expenditures have escalated sharply despite some worldwide declines in military personnel. Theories on the economic impacts of the military institution and escalated military spending greatly differ and include arguments that they either improve domestic economic performance or crowd out growth-inducing processes. Empirical findings on this matter are inconclusive, in part due to a failure to disentangle the various dimensions of military expenditures. We further suggest that modern sociology's relative inattention to such issues has contributed to these shortcomings. We explore a new dimension of military spending that clarifies this issue—military expenditures per soldier —which captures the capital intensiveness of a country’s military organization. Our cross-national panel regression and causal analyses of developed and less developed countries from 1990 to 2003 show that military expenditures per soldier inhibit the growth of per capita GDP, net of control variables, with the most pronounced effects in least developed countries. These expenditures inhibit national development in part by slowing the expansion of the labor force. Labor-intensive militaries may provide a pathway for upward mobility, but comparatively capital-intensive military organizations limit entry opportunities for unskilled and under- or unemployed people. Deep investments in military hardware also reduce the investment capital available for more economically productive opportunities. We also find that arms imports have a positive effect on economic growth, but only in less developed countries.

A hybrid magnetic approach, merging two different magnetic core properites such as ferrite and iron powder cores, is an effective solution for power converter applications. It can offer similar magnetic properties to that of magnetic powder cores but showing less copper loss than powder cores....... In order to prevent ferrite core saturation, placing an effective air gap within the ferrite core is a key method to obtain optimum hybrid magnetic performance. Furthermore, a relatively large inductance at low loading current is an excellent way to minimze power loss in order to achieve high efficiency...

Implementing Internet of Things in a military command and control environment

Science.gov (United States)

Raglin, Adrienne; Metu, Somiya; Russell, Stephen; Budulas, Peter

2017-05-01

While the term Internet of Things (IoT) has been coined relatively recently, it has deep roots in multiple other areas of research including cyber-physical systems, pervasive and ubiquitous computing, embedded systems, mobile ad-hoc networks, wireless sensor networks, cellular networks, wearable computing, cloud computing, big data analytics, and intelligent agents. As the Internet of Things, these technologies have created a landscape of diverse heterogeneous capabilities and protocols that will require adaptive controls to effect linkages and changes that are useful to end users. In the context of military applications, it will be necessary to integrate disparate IoT devices into a common platform that necessarily must interoperate with proprietary military protocols, data structures, and systems. In this environment, IoT devices and data will not be homogeneous and provenance-controlled (i.e. single vendor/source/supplier owned). This paper presents a discussion of the challenges of integrating varied IoT devices and related software in a military environment. A review of contemporary commercial IoT protocols is given and as a practical example, a middleware implementation is proffered that provides transparent interoperability through a proactive message dissemination system. The implementation is described as a framework through which military applications can integrate and utilize commercial IoT in conjunction with existing military sensor networks and command and control (C2) systems.

Smart Power: New power integrated circuit technologies and their applications

Science.gov (United States)

Kuivalainen, Pekka; Pohjonen, Helena; Yli-Pietilae, Timo; Lenkkeri, Jaakko

1992-05-01

Power Integrated Circuits (PIC) is one of the most rapidly growing branches of the semiconductor technology. The PIC markets has been forecast to grow from 660 million dollars in 1990 to 1658 million dollars in 1994. It has even been forecast that at the end of the 1990's the PIC markets would correspond to the value of the whole semiconductor production in 1990. Automotive electronics will play the leading role in the development of the standard PIC's. Integrated motor drivers (36 V/4 A), smart integrated switches (60 V/30 A), solenoid drivers, integrated switch-mode power supplies and regulators are the latest standard devices of the PIC manufactures. ASIC (Application Specific Integrated Circuits) PIC solutions are needed for the same reasons as other ASIC devices: there are no proper standard devices, a company has a lot of application knowhow, which should be kept inside the company, the size of the product must be reduced, and assembly costs are wished to be reduced by decreasing the number of discrete devices. During the next few years the most probable ASIC PIC applications in Finland will be integrated solenoid and motor drivers, an integrated electronic lamp ballast circuit and various sensor interface circuits. Application of the PIC technologies to machines and actuators will strongly be increased all over the world. This means that various PIC's, either standard PIC's or full custom ASIC circuits, will appear in many products which compete with the corresponding Finnish products. Therefore the development of the PIC technologies must be followed carefully in order to immediately be able to apply the latest development in the smart power technologies and their design methods.

Thermoacoustic power systems for space applications

International Nuclear Information System (INIS)

Backhaus, S.N.; Tward, E.; Pedach, M.

2001-01-01

Future NASA deep-space missions will require radioisotope-powered electric generators that are just as reliable as current RTGs, but more efficient and of higher specific power (W/kg). Thermoacoustic engines can convert high-temperature heat into acoustic, or PV, power without moving parts at 30% efficiency. Consisting of only tubes and a few heat exchangers, these engines are low mass and promise to be highly reliable. Coupling a thermoacoustic engine to a low-mass, highly reliable and efficient linear alternator will create a heat-driven electric generator suitable for deep-space applications. Data will be presented on the first tests of a demonstration thermoacoustic engine designed for the 100-Watt power range.

Full Text Available The article sheds light on the origins of the military technical thinking in the military publishing of the Kingdom of Serbia with a view to marking a jubilee - the sixtieth anniversary of the Military Technical Courier. 'Vojin', the first military review, printed in the middle of 19th century as a private venture, covered a wide scope of military issues, among which a special place was given to 'the science of weapons'. No sooner had this review ceased to exist than The Headquarters of the Army of the Kingdom of Serbia started publishing a new military review, 'Ratnik', which, apart from the art of war and war literature, dealt with the science of weapons in order to inform officers about the latest achievements in military technology and to educate them as well. Serbian military thinking, including its technical aspect, did not fall behind modern trends in its European and world counterparts until 1914. The development of weaponry in Europe and the world was regularly covered on the pages of military reviews.

Research suggests that men are less likely to seek help for depression, substance abuse, and stressful life events due to negative perceptions of asking for and receiving help. This may be exacerbated in male military cadets who exhibit higher levels of gender role conflict because of military culture. This exploratory study examined the perceptions of 78 male military cadets toward help-seeking behaviors. Cadets completed the 31-item Barriers to Help Seeking Scale (BHSS) and a component factor analysis was used to generate five composite variables and compare to validated factors. Perceptual mapping and vector modeling, which produce 3-dimensional models of a group's perceptions, were then used to model how they conceptualize help-seeking. Factor analysis showed slightly different groupings than the BHSS, perhaps attributed to different characteristics of respondents, who are situated in a military school compared to general university males. Perceptual maps show that cadets perceive trust of doctors closest to them and help-seeking farthest, supporting the concept that these males have rigid beliefs about having control and its relationship to health seeking. Differences were seen when comparing maps of White and non-White cadets. White cadets positioned themselves far away from all variables, while non-White cadets were closest to "emotional control". To move these cadets toward help-seeking, vector modeling suggests that interventions should focus on their general trust of doctors, accepting lack of control, and decreasing feelings of weakness when asking for help. For non-White cadets a focus on self-reliance may also need to be emphasized. Use of these unique methods resulted in articulation of specific barriers that if addressed early, may have lasting effects on help-seeking behavior as these young men become adults. Future studies are needed to develop and test specific interventions to promote help-seeking among military cadets.

Full Text Available Implantable biosensing is attractive for both medical monitoring and diagnostic applications. It is possible to monitor phenomena such as physical loads on joints or implants, vital signs, or osseointegration in vivo and in real time. Microelectromechanical (MEMS-based generation techniques can allow for the autonomous operation of implantable biosensors by generating electrical power to replace or supplement existing battery-based power systems. By supplementing existing battery-based power systems for implantable biosensors, the operational lifetime of the sensor is increased. In addition, the potential for a greater amount of available power allows additional components to be added to the biosensing module, such as computational and wireless and components, improving functionality and performance of the biosensor. Photovoltaic, thermovoltaic, micro fuel cell, electrostatic, electromagnetic, and piezoelectric based generation schemes are evaluated in this paper for applicability for implantable biosensing. MEMS-based generation techniques that harvest ambient energy, such as vibration, are much better suited for implantable biosensing applications than fuel-based approaches, producing up to milliwatts of electrical power. High power density MEMS-based approaches, such as piezoelectric and electromagnetic schemes, allow for supplemental and replacement power schemes for biosensing applications to improve device capabilities and performance. In addition, this may allow for the biosensor to be further miniaturized, reducing the need for relatively large batteries with respect to device size. This would cause the implanted biosensor to be less invasive, increasing the quality of care received by the patient.

Full Text Available In the present study the author disclosed the role of pronoia in the military organization of the Byzantine Empire at early Palaeologian period. The concrete cases of the award allow recognizing the proniarety as the Byzantine military institution dealing exclusively with the military leadership. The grant of pronoia was a replacement for traditional rewards of military commanders of noble birth. However, in some cases it was identified that compulsory military service was a function of power which was granted to the proniares in addition to the tax quota. Holders of pronoia were not only the Romans military commanders but also the mercenaries. Such awards could reduce the costs of imperial treasury for direct payments. In the case of proniares-Byzantines, depending on posotis, we can talk about the conferring upon pronoia the representatives of various levels of the military leadership. The pronoias granted as a reward or the compensation for losses incurred as a result of the performance of official engagements, could be transferred to the commanders of low levels which were recruited from among stratiotes (obviously, dekarhes.

Full Text Available As the Crimean Crisis goes on, many analysis have been focusing on the dynamics among parties of Ukraine, the EU, the US and Russia. Very few noticed another important strategic impact the Crisis may cause: the Chinese military rebalancing in East Asia. China has been increasingly confident in assuming both political and military power in the East Asian region. The confidence resulted in the South China Sea disputes with ASEAN countries, “Anti-Secession Law” against Taiwan, and the Diaoyu/Senkaku Islands Dispute with Japan. Behind such confidence of China, the EU has consistently been exporting defence products to China since the end of the Cold War; Ukraine, although sometimes reluctantly, has also been backing China along the process of building up a stronger navy as well as other defense industry construction; Russia has traditionally been supplying China with a wide range of military hardware. It can be noticed that the Crimean Crisis involved three out of four countries and region that have been behind China’s rise. How will the Crimean Crisis influence China’s rebalance in East Asia then? The answers stay opaque. This paper will attempt to answer the questions.

Fiber optic applications in nuclear power plants

International Nuclear Information System (INIS)

Collette, P.; Kwapien, D.

1984-01-01

Fiber optic technology possesses many desirable attributes for applications in commercial nuclear power plants. The non-electrical nature of fiber optics is an important factor in an industry governed by federal safety regulations such as Class 1E isolation and separation criteria. Immunity from Electromagnetic Interference (EMI), an increasing industry problem area, is another significant characteristic. Because of the extremely wide bandwidth offered, fiber optics better addresses the data acquistion and communication requirements of the complex processes of a nuclear power plant. Potential for fiber optic sensor applications exists within the nuclear industry because their small size and physical flexibility allows access into normally inaccessible areas. They possess high accuracy and allow environmentally sensitive electronics to be remotely located. The purpose of this paper is to explore current applications for fiber optic technology in modern nuclear plants, document examples of present day usage in C-E plants and suggest possible future application areas

THE VISUAL POLITICS OF PORTRAYING POWER: IMAGES OF THE POLICE AND MILITARY IN STOCK PHOTOGRAPHY

Directory of Open Access Journals (Sweden)

Michaelene Cox

2016-01-01

Full Text Available Visualizing power is an imaginative and multifaceted undertaking. Those who can use imagery to harness and transform cultural expectations about authority can influence how societies face current and future challenges. For instance, we find a concern with security to be one of the most pressing issues at the individual, state and international levels. Perceptions of law enforcement and the armed services certainly have bearing on our confidence in those institutions to safeguard lives, property and cultural values. We understand that impressions mirror reality to varying degree and are manipulated by a myriad of forces, including nonverbal communication. It is valuable then to consider the nature of images furnished today for public consumption. Photographs from one of the world’s largest electronic image banks reveal attributes of contemporary representations of the military and police. Although such collections have not been mined by many scholars yet, the study herein finds room for considerable investigation and reflection across disciplines about the role of stock photography in shaping and reflecting cultural norms and identities.

Isotope powered Stirling generator for terrestrial applications

Tingey, G.L.; Sorensen, G.C.; Ross, B.A.

1995-01-01

An electric power supply, small enough to be man-portable, is being developed for remote, terrestrial applications. This system is designed for an operating lifetime of five years without maintenance or refueling. A small Radioisotope Stirling Generator (RSG) has been developed. The energy source of the generator is a 60 watt plutonium-238 fuel clad used in the General Purpose Heat Sources (GPHS) developed for space applications. A free piston Stirling Engine drives a linear alternator to convert the heat to power. The system weighs about 7.5 kg and produces 11 watts AC power with a conversion efficiency of 18.5%. Two engine models have been designed, fabricated, and tested to date: (a) a developmental model instrumented to confirm and test parameters, and (b) an electrically heated model with an electrical heater equipped power input leads. Critical components have been tested for 10,000 to 20,000 hours. One complete generator has been operating for over 11,000 hours. Radioisotope heated prototypes are expected to be fabricated and tested in late 1995

Risk mitigation process for utilization of commercial off-the-shelf (COTS) parts in CCD camera for military applications

Ahmad, Anees; Batcheldor, Scott; Cannon, Steven C.; Roberts, Thomas E.

2002-09-01

This paper presents the lessons learned during the design and development of a high performance cooled CCD camera for military applications utilizing common commercial off the shelf (COTS) parts. Our experience showed that concurrent evaluation and testing of high risk COTS must be performed to assess their performance over the required temperature range and other special product requirements such as fuel vapor compatibility, EMI and shock susceptibility, etc. Technical, cost and schedule risks for COTS parts must also be carefully evaluated. The customer must be involved in the selection and evaluation of such parts so that the performance limitations of the selected parts are clearly understood. It is equally important to check with vendors on the availability and obsolescence of the COTS parts being considered since the electronic components are often replaced by newer, better and cheaper models in a couple of years. In summary, this paper addresses the major benefits and risks associated with using commercial and industrial parts in military products, and suggests a risk mitigation approach to ensure a smooth development phase, and predictable performance from the end product.

Low Energy Reaction cell for advanced space power applications

International Nuclear Information System (INIS)

Miley, George H.; Rice, Eric

2001-01-01

Power units using Low Energy Reactions (LENRs) are under study as a radical new approach to power units that could potentially replace nuclear and chemical power sources for a number of space applications. These cells employ thin metallic films (order of 500 deg., using variously Ni, Pd and Ti) as cathodes with various electrolytes such as 0.5-1 molar lithium sulfate in light water. Power densities exceeding 10 W/cm3 in the thin-films have been achieved. An ultimate goal is to incorporate this thin-film technology into a 'tightly packed' cell design where the film material occupies ∼20% of the total cell volume. If this is achieved, overall power densities of ∼20 W/cm3 appear feasible, opening the way to a number of potential applications ranging from distributed power units in spacecraft to advanced propulsion

Evaluating the power consumption of wireless sensor network applications using models.

Dâmaso, Antônio; Freitas, Davi; Rosa, Nelson; Silva, Bruno; Maciel, Paulo

2013-03-13

Power consumption is the main concern in developing Wireless Sensor Network (WSN) applications. Consequently, several strategies have been proposed for investigating the power consumption of this kind of application. These strategies can help to predict the WSN lifetime, provide recommendations to application developers and may optimize the energy consumed by the WSN applications. While measurement is a known and precise strategy for power consumption evaluation, it is very costly, tedious and may be unfeasible considering the (usual) large number of WSN nodes. Furthermore, due to the inherent dynamism of WSNs, the instrumentation required by measurement techniques makes difficult their use in several different scenarios. In this context, this paper presents an approach for evaluating the power consumption of WSN applications by using simulation models along with a set of tools to automate the proposed approach. Starting from a programming language code, we automatically generate consumption models used to predict the power consumption of WSN applications. In order to evaluate the proposed approach, we compare the results obtained by using the generated models against ones obtained by measurement.

Green Applications for Space Power Project

Spacecraft propulsion and power for many decades has relied on Hydrazine monopropellant technology for auxiliary power units (APU), orbital circularization, orbit raising/lowering and attitude control. However, Hydrazine is toxic and therefore requires special ground handling procedures to ensure launch crew safety. The Swedish Company ECAPS has developed a technology based upon the propellant Ammonium Dinitramide (ADN) that offers higher performance, higher density and reduced ground handling support than Hydrazine. This blended propellant is called LMP-103S. Currently, the United States Air Force (USAF) is pursuing a technology based on Hydroxyl Ammonium Nitrate (HAN, otherwise known as AF-M315E) with industry partners Aerojet and Moog. Based on the advantages offered by these propellants, MSFC should explore powering APU's with these propellants. Due to the availability of space hardware, the principal investigator has found a collection of USAF hardware, that will act as a surrogate, which operates on a Hydrazine derivative. The F-16 fighter jet uses H-70 or 30% diluted Hydrazine for an Emergency Power Unit (EPU) which supplies power to the plane. The PI has acquired two EPU's from planes slated for destruction at the Davis Monthan AFB. This CIF will include a partnership with 2 other NASA Centers who are individually seeking seed funds from their respective organizations: Kennedy Space Center (KSC) and Dryden Flight Research Center (DFRC). KSC is preparing for future flights from their launch pads that will utilize green propellants and desire a low-cost testbed in which to test and calibrate new leak detection sensors. DFRC has access to F-16's which can be used by MSFC & KSC to perform a ground test that demonstrates emergency power supplied to the jet. Neither of the green propellant alternatives have been considered nor evaluated for an APU application. Work has already been accomplished to characterize and obtain the properties of these 2 propellants

Just as Duchêne’s civilian power reflected the Cold War milieu of the 1970s......There is a widespread belief that the European Union (EU) is a novel kind of power not only in its own institutional set-up but also in its external relations. It is said to rely on civilian rather than military means and to pursue the spread of particular norms rather than self......, the normative power approach signified a crystallisation of the EU in the post-Cold War era....

2018-01-01

Full Text Available The development of the Chilean military industry is closely related to the growing of the national industry. Similarly to the way the history of the Army and the country are tightly related, the history of the military engineering is an example of organic growth when compared to its civilian counterpart. Collaboration instead of competition is the distinctive seal that best shows the development of weaponry, explosives, cartography and nuclear power. This collaboration have lasted with the years and we can afirm today that the relationship within civilian professionals and technicians and their military counterparts has reached an state that has never seen before. The governmental policies that fund R&D of initiatives that facilitate the science and technology study and research, come of a futuristic vision, born in the rim of the independent movements, driven naturally by the need of self sustain as sovereign nations.

This is a presentation on high-power electron accelerators for space and other applications. The main points covered are: electron beams for space applications, new designs of RF accelerators, high-power high-electron mobility transistors (HEMT) testing, and Li-ion battery design. In summary, the authors have considered a concept of 1-MeV electron accelerator that can operate up to several seconds. This concept can be extended to higher energy to produce higher beam power. Going to higher beam energy requires adding more cavities and solid-state HEMT RF power devices. The commercial HEMT have been tested for frequency response and RF output power (up to 420 W). Finally, the authors are testing these HEMT into a resonant load and planning for an electron beam test in FY17.

Agricultural and Food Processing Applications of Pulsed Power and Plasma Technologies

Science.gov (United States)

Takaki, Koichi

Agricultural and food processing applications of pulsed power and plasma technologies are described in this paper. Repetitively operated compact pulsed power generators with a moderate peak power are developed for the agricultural and the food processing applications. These applications are mainly based on biological effects and can be categorized as germination control of plants such as Basidiomycota and arabidopsis inactivation of bacteria in soil and liquid medium of hydroponics; extraction of juice from fruits and vegetables; decontamination of air and liquid, etc. Types of pulsed power that have biological effects are caused with gas discharges, water discharges, and electromagnetic fields. The discharges yield free radicals, UV radiation, intense electric field, and shock waves. Biologically based applications of pulsed power and plasma are performed by selecting the type that gives the target objects the adequate result from among these agents or byproducts. For instance, intense electric fields form pores on the cell membrane, which is called electroporation, or influence the nuclei. This paper mainly describes the application of the pulsed power for the germination control of Basidiomycota i.e. mushroom, inactivation of fungi in the soil and the liquid medium in hydroponics, and extraction of polyphenol from skins of grape.

Buden, D.; Albert, T.

1987-01-01

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 Importance of Military Cultural Competence.

Science.gov (United States)

Meyer, Eric G; Writer, Brian W; Brim, William

2016-03-01

Military cultural competence has recently gained national attention. Experts have posited that limited outcomes in the treatment of posttraumatic stress disorder and depression in the military may be related to limited familiarity with the military. National surveys have indicated low military cultural competence among providers and limited educational efforts on military culture or pertinent military pathology in medical schools and residency training programs. Military families, with their own unique military cultural identity, have been identified as a population with increased risks associated with deployment. In response to these findings, several curricula regarding military culture have been established and widely distributed. Assessments of military cultural competence have also been developed. The clinical impact of enhanced cultural competence in general has thus far been limited. The military, however, with its highly prescribed cultural identity, may be a model culture for further study.

Military mothers and their children cope with unique issues when mothers are deployed. In this article, we present mothers' perspectives on how military resources affected them, their children, and their caregivers during deployment. Mothers described beneficial features of military programs such as family readiness groups and behavioral health care, processes such as unit support, and policies on length and timing of deployments. Aspects that were not supportive included inflexibility in family care plans, using personal leave time and funds for transporting children, denial of release to resolve caretaker issues, and limited time for reintegration. We offer recommendations for enhanced support to these families that the military could provide. Reprint & Copyright © 2013 Association of Military Surgeons of the U.S.

2017-09-01

In the Republic of Kazakhstan military service becomes attractive primarily for that category of people who have no opportunity to acquire high quality vocational or higher education, decent income by the speciality available, or those who have not yet identified themselves professionally and socially. Its a serious problem how to ensure ability of military units to execute their service duties in conditions of more and more increasing requirements for professional competences of military personnel, increased intellectualization of military service when the quality of "human material" often is not corresponding to the required standards. This problem in the national and foreign science is still being developed and has no final solutions accessible for the scientific society. This article presents an effort to offer specialists in the military administration area one of probable tools to forecast successfulness of execution of professional tasks by military units based on results of sociometric studies and algorithms of plotting Bayesian networks. Using these tools a military leader will be able to evaluate effectiveness of his managerial activity, correct mechanisms of individual and mentoring activity with regard to individual servicemen, provide an opportunity to eliminate risks of failing to fulfill professional tasks on time and failing to ensure combat readiness of entrusted military team.

Planar optical waveguides for civil and military applications

International Nuclear Information System (INIS)

Lavers, C R

2009-01-01

There is significant military and civil interest in being able to detect chemical species adsorbed from air or present in aqueous solutions. Planar optical waveguide transmission properties are sensitive to changes in parameters such as refractive index or absorption and to light-emitting processes such as fluorescence. These changes modulate light travelling in optical waveguides, and so may be used as sensors for detecting biological and chemical agents, non-ionizing and ionizing electromagnetic radiation. Several waveguide systems have been studied theoretically and experimentally, and their responses to basic influences such as alcohol and UV radiation, and gamma rays determined.

1996-12-31

During the past year Analytic Power has tested fuel cell stacks and diesel fuel processors for US Navy and Marine Corps applications. The units are 10 kW demonstration power plants. The USN power plant was built to demonstrate the feasibility of diesel fueled PEM fuel cell power plants for 250 kW and 2.5 MW shipboard power systems. We designed and tested a ten cell, 1 kW USMC substack and fuel processor. The complete 10 kW prototype power plant, which has application to both power and hydrogen generation, is now under construction. The USN and USMC fuel cell stacks have been tested on both actual and simulated reformate. Analytic Power has accumulated operating experience with autothermal reforming based fuel processors operating on sulfur bearing diesel fuel, jet fuel, propane and natural gas. We have also completed the design and fabrication of an advanced regenerative ATR for the USMC. One of the significant problems with small fuel processors is heat loss which limits its ability to operate with the high steam to carbon ratios required for coke free high efficiency operation. The new USMC unit specifically addresses these heat transfer issues. The advances in the mill programs have been incorporated into Analytic Power`s commercial units which are now under test.

Jacobson, David T.; Manzella, David H.

2004-01-01

The NASA Glenn Research Center has been performing research and development of moderate specific impulse, xenon-fueled, high-power Hall thrusters for potential solar electric propulsion applications. These applications include Mars missions, reusable tugs for low-Earth-orbit to geosynchronous-Earth-orbit transportation, and missions that require transportation to libration points. This research and development effort resulted in the design and fabrication of the NASA-457M Hall thruster that has been tested at input powers up to 95 kW. During project year 2003, NASA established Project Prometheus to develop technology in the areas of nuclear power and propulsion, which are enabling for deep-space science missions. One of the Project-Prometheus-sponsored Nuclear Propulsion Research tasks is to investigate alternate propellants for high-power Hall thruster electric propulsion. The motivation for alternate propellants includes the disadvantageous cost and availability of xenon propellant for extremely large scale, xenon-fueled propulsion systems and the potential system performance benefits of using alternate propellants. The alternate propellant krypton was investigated because of its low cost relative to xenon. Krypton propellant also has potential performance benefits for deep-space missions because the theoretical specific impulse for a given voltage is 20 percent higher than for xenon because of krypton's lower molecular weight. During project year 2003, the performance of the high-power NASA-457M Hall thruster was measured using krypton as the propellant at power levels ranging from 6.4 to 72.5 kW. The thrust produced ranged from 0.3 to 2.5 N at a discharge specific impulse up to 4500 sec.

Pronoia in the Military Organization of the Byzantine Empire at Early Palaeologian Period (Part 2

Directory of Open Access Journals (Sweden)

Zolotovskiy Vladimir A.

2016-06-01

Full Text Available In the present study the author disclosed the role of pronoia in the military organization of the Byzantine Empire at early Palaeologian period. The concrete cases of the award allow recognizing the proniarety as the Byzantine military institution dealing exclusively with the military leadership. The grant of pronoia was a replacement for traditional rewards of military commanders of noble origin. However, in some cases it was identified that compulsory military service was a function of power which was granted to the proniares in addition to the tax quota. Holders of pronoia were not only the Romans military commanders but also the mercenaries. Such awards could reduce the costs of imperial treasury for direct payments. In the case of proniares-Byzantines, depending on posotis, we can talk about the conferring upon pronoia the representatives of various levels of the military leadership. The pronoias granted as a reward or the compensation for losses incurred as a result of the performance of official engagements, could be transferred to the commanders of low levels which were recruited from among stratiotes (obviously, dekarhes. Definition of the role of pronoia in military practice of the early palaeologian period which would be possible in the identification of the proportion of pronoiares and strateia contingents and the correlation of victories and defeats, won by them, is impossible in practice.

Fiber lasers are now attracting more and more research interest due to their advantages in efficiency, beam quality and flexible operation. Up to now, most of the high power fiber lasers have random distributed polarization state. Linearlypolarized (LP) fiber lasers, which could find wide application potential in coherent detection, coherent/spectral beam combining, nonlinear frequency conversion, have been a research focus in recent years. In this paper, we will present a general review on the achievements of various kinds of high power linear-polarized fiber laser and its application. The recent progress in our group, including power scaling by using power amplifier with different mechanism, high power linearly polarized fiber laser with diversified properties, and various applications of high power linear-polarized fiber laser, are summarized. We have achieved 100 Watt level random distributed feedback fiber laser, kilowatt level continuous-wave (CW) all-fiber polarization-maintained fiber amplifier, 600 watt level average power picosecond polarization-maintained fiber amplifier and 300 watt level average power femtosecond polarization-maintained fiber amplifier. In addition, high power linearly polarized fiber lasers have been successfully applied in 5 kilowatt level coherent beam combining, structured light field and ultrasonic generation.

Winter, J.M.

1991-09-01

The SP-100 program was established in 1983 by DOD, DOE, and NASA as a joint program to develop the technology necessary for space nuclear power systems for military and civil applications. During 1986 and 1987, the NASA Advanced Technology Program was responsible for maintaining the momentum of promising technology advancement efforts started during Phase 1 of SP-100 and to strengthen, in key areas, the chances for successful development and growth capability of space nuclear reactor power systems for future space applications. In 1988, the NASA Advanced Technology Program was incorporated into NASA's new Civil Space Technology Initiative (CSTI). The CSTI program was established to provide the foundation for technology development in automation and robotics, information, propulsion, and power. The CSTI High Capacity Power Program builds on the technology efforts of the SP-100 program, incorporates the previous NASA advanced technology project, and provides a bridge to the NASA exploration technology programs. The elements of CSTI high capacity power development include conversion systems: Stirling and thermoelectric, thermal management, power management, system diagnostics, and environmental interactions. Technology advancement in all areas, including materials, is required to provide the growth capability, high reliability, and 7 to 10 year lifetime demanded for future space nuclear power systems. The overall program will develop and demonstrate the technology base required to provide a wide range of modular power systems while minimizing the impact of day/night operations as well as attitudes and distance from the Sun. Significant accomplishments in all of the program elements will be discussed, along with revised goals and project timelines recently developed

Objective This review discusses the current knowledge and future directions regarding obesity within the US military family (i.e., active-duty servicemembers, as well as military spouses, children, retirees, and veterans). The increasing rates of overweight and obesity within the US military adversely impact military readiness, limit recruitment, and place a significant financial burden on the Department of Defense. Design and Methods The following topics are reviewed: 1) The prevalence of and the financial, physical, and psychological costs associated with overweight in military communities; 2) military weight regulations, and challenges faced by the military family related to overweight and disordered eating; 3) the continued need for rigorous program evaluations and new intervention development. Results Overweight and its associated sequelae impact the entire military family. Military families share many similarities with their civilian counterparts, but they face unique challenges (e.g., stress related to deployments and relocations). Although the military has weight management resources, there is an urgent need for rigorous program evaluation and the development of enhanced obesity prevention programs across the lifespan of the military family–several of which are proposed herein. Conclusions Interdisciplinary and collaborative research efforts and team-based interventions will continue to inform understanding of obesity treatment and prevention within military and civilian populations.

Military suicide rates have been rising over the past decade and continue to challenge military treatment facilities. Assessing suicide risk and improving treatments are a large part of the mission for clinicians who work with uniformed service members. This study attempts to expand the toolkit of military suicide prevention by focusing on protective factors over risk factors. In 1983, Marsha Linehan published a checklist called the Reasons for Living Scale, which asked subjects to check the reasons they choose to continue living, rather than choosing suicide. The authors of this article hypothesized that military service members may have different or additional reasons to live which may relate to their military service. They created a new version of Linehan's inventory by adding protective factors related to military life. The purpose of these additions was to make the inventory more acceptable and relevant to the military population, as well as to identify whether these items constitute a separate subscale as distinguished from previously identified factors. A commonly used assessment tool, the Reasons for Living Inventory (RFL) designed by Marsha Linehan, was expanded to offer items geared to the military population. The RFL presents users with a list of items which may be reasons to not commit suicide (e.g., "I have a responsibility and commitment to my family"). The authors used focus groups of staff and patients in a military psychiatric partial hospitalization program to identify military-centric reasons to live. This process yielded 20 distinct items which were added to Linehan's original list of 48. This expanded list became the Reasons for Living-Military Version. A sample of 200 patients in the military partial hospitalization program completed the inventory at time of or close to admission. This study was approved by the Institutional Review Board at Walter Reed National Military Center for adhering to ethical principles related to pursuing research

2018-02-21

Forensic biometrics is the application of forensic science principles to physical and behavioral characteristics. Forensic biometrics is a secondary sub-system in the forensic science "system of systems," which describes forensic science as a sub-system in the larger criminal justice, law enforcement, intelligence, and military system. The purpose of this paper is to discuss biometrics in the military domain and integration into the wider forensic science system of systems. The holistic system thinking methodology was applied to the U.S. biometric system to map it to the system of systems framework. The U.S. biometric system is used as a case study to help guide other countries to develop military biometric systems that are integrated and interoperable at the whole-of-government level. The aim is to provide the system of systems framework for agencies to consider for proactive design of biometric systems. © 2018 American Academy of Forensic Sciences.

Environmental Assessment for Central Power and Light Company`s proposed Military Highway-CFE tie 138/69-kV transmission line project Brownsville, Cameron County, Texas

Energy Technology Data Exchange (ETDEWEB)

1992-04-01

Central Power and Light Company (CPL) intends to upgrade its existing transmission line ties with the Commision Federal de Electricidad (CFE) system in Mexico. CPL currently has a single 69-kilovolt (kV) transmission line in the Brownsville area which connects CPL`s system with the system of CFE. This existing line runs between the Brownsville Switching Station, located on Laredo Road in Brownsville, Cameron County, Texas, and an existing CFE 69-kV line at the Rusteberg Bend of the Rio Grande in Cameron County. Under current conditions of need, the existing 69-kV line does not possess sufficient capability to engage in appropriate power exchanges. Therefore, CPL is proposing to build a new line to link up with CFE. This proposed line would be a double-circuit line, which would (1) continue (on a slightly relocated route) the existing 69-kV tie from CPL`s Brownsville Switching Station to CFE`s facilities, and (2) add a 138-kV tie from the Military Highway Substation, located on Military Highway (US Highway 281), to CFE`s facilities. The proposed 138/69-kV line, which will be constructed and operated by CPL, will be built primarily on steel single-pole structures within an average 60-foot (ft) wide right-of-way (ROW). It will be approximately 6900--9200 ft (1.3--1.7 miles) in length, depending on the alternative route constructed.

U.S. Army Corrosion Office's storage and quality requirements for military MEMS program

2007-04-01

As the Army transforms into a more lethal, lighter and agile force, the technologies that support these systems must decrease in size while increasing in intelligence. Micro-electromechanical systems (MEMS) are one such technology that the Army and DOD will rely on heavily to accomplish these objectives. Conditions for utilization of MEMS by the military are unique. Operational and storage environments for the military are significantly different than those found in the commercial sector. Issues unique to the military include; high G-forces during gun launch, extreme temperature and humidity ranges, extended periods of inactivity (20 years plus) and interaction with explosives and propellants. The military operational environments in which MEMS will be stored or required to function are extreme and far surpass any commercial operating conditions. Security and encryption are a must for all MEMS communication, tracking, or data reporting devices employed by the military. Current and future military applications of MEMS devices include safety and arming devices, fuzing devices, various guidance systems, sensors/detectors, inertial measurement units, tracking devices, radio frequency devices, wireless Radio Frequency Identifications (RFIDs) and network systems, GPS's, radar systems, mobile base systems and information technology. MEMS embedded into these weapons systems will provide the military with new levels of speed, awareness, lethality, and information dissemination. The system capabilities enhanced by MEMS will translate directly into tactical and strategic military advantages.

Industrial Applications of High Average Power FELS

CERN Document Server

Shinn, Michelle D

2005-01-01

The use of lasers for material processing continues to expand, and the annual sales of such lasers exceeds $1 B (US). Large scale (many m2) processing of materials require the economical production of laser powers of the tens of kilowatts, and therefore are not yet commercial processes, although they have been demonstrated. The development of FELs based on superconducting RF (SRF) linac technology provides a scaleable path to laser outputs above 50 kW in the IR, rendering these applications economically viable, since the cost/photon drops as the output power increases. This approach also enables high average power ~ 1 kW output in the UV spectrum. Such FELs will provide quasi-cw (PRFs in the tens of MHz), of ultrafast (pulsewidth ~ 1 ps) output with very high beam quality. This talk will provide an overview of applications tests by our facility's users such as pulsed laser deposition, laser ablation, and laser surface modification, as well as present plans that will be tested with our upgraded FELs.

Due to the complex and integrated nature of a power system, failures in any part of the system can cause interruptions, which range from inconveniencing a small number of local residents to a major and widespread catastrophic disruption of supply known as blackout. The objective of the paper is to show that the methods and tools of probabilistic safety assessment are applicable for assessment and improvement of real power systems. The method used in this paper is developed based on the fault tree analysis and is adapted for the power system reliability analysis. A particular power system i.e. the Macedonian power system is the object of the analysis. The results show that the method is suitable for application of real systems. The reliability of Macedonian power system assumed as the static system is assessed. The components, which can significantly impact the power system are identified and analysed in more details.

Since the last decade power systems underlie a drastic change due to increased exploitation of renewable energy resources (RES) such as wind and photovoltaic power plants. A result of this process is a significant increase of fluctuating generation in low, middle and high voltage grids. Consequently, impacts on short and middle term capacity planning of power plants occur and must be handled to avoid imbalances between generation and demand at any time. Therefore, forecasts of wind and photovoltaic generation play a very important role. Quality improvements potentially ease planning and lead to cost reductions. This work investigated the dependencies of input parameters. The optimal parameter selection was achieved through application of data mining methods. Finally, the wind power prediction was demonstrated with Artificial Neural Networks and Physical Models. (orig.)

This paper considers an application of Newton's optimal power flow to the solution of the secondary voltage/reactive power control in transmission networks. An efficient computer program based on the latest achievements in the sparse matrix/vector techniques has been developed for this purpose. It is characterized by good robustness, accuracy and speed. A combined objective function appropriate for various system load levels with suitable constraints, for treatment of the power system security and economy is also proposed. For the real-time voltage/reactive power control, a suboptimal power flow procedure has been derived by using the reduced set of control variables. This procedure is based on the sensitivity theory applied to the determination of zones for the secondary voltage/reactive power control and corresponding reduced set of regulating sources, whose reactive outputs represent control variables in the optimal power flow program. As a result, the optimal power flow program output becomes a schedule to be used by operators in the process of the real-time voltage/reactive power control in both normal and emergency operating states.

Tensions on the Korean Peninsula remain high despite a long-term strategy by South Korea to increase inter-Korean exchanges in economics, culture, sports, and other topics. This is because the process of reconciliation has rarely extended to military and security topics and those initiatives that were negotiated have been ineffective. Bilateral interactions must include actions to reduce threats and improve confidence associated with conventional military forces (land, sea, and air) as well as nuclear, chemical, and biological activities that are applicable to developing and producing weapons of mass destruction (WMD). The purpose of this project is to develop concepts for inter-Korean confidence building measures (CBMs) for military and WMD topics that South Korea could propose to the North when conditions are right. This report describes the historical and policy context for developing security-related CBMs and presents an array of bilateral options for conventional military and WMD topics within a consistent framework. The conceptual CBMs address two scenarios: (1) improved relations where construction of a peace regime becomes a full agenda item in inter-Korean dialogue, and (2) continued tense inter-Korean relations. Some measures could be proposed in the short term under current conditions, others might be implemented in a series of steps, while some require a higher level of cooperation than currently exists. To support decision making by political leaders, this research focuses on strategies and policy options and does not include technical details.

Energy Storage Applications in Power Systems with Renewable Energy Generation

Science.gov (United States)

Ghofrani, Mahmoud

In this dissertation, we propose new operational and planning methodologies for power systems with renewable energy sources. A probabilistic optimal power flow (POPF) is developed to model wind power variations and evaluate the power system operation with intermittent renewable energy generation. The methodology is used to calculate the operating and ramping reserves that are required to compensate for power system uncertainties. Distributed wind generation is introduced as an operational scheme to take advantage of the spatial diversity of renewable energy resources and reduce wind power fluctuations using low or uncorrelated wind farms. The POPF is demonstrated using the IEEE 24-bus system where the proposed operational scheme reduces the operating and ramping reserve requirements and operation and congestion cost of the system as compared to operational practices available in the literature. A stochastic operational-planning framework is also proposed to adequately size, optimally place and schedule storage units within power systems with high wind penetrations. The method is used for different applications of energy storage systems for renewable energy integration. These applications include market-based opportunities such as renewable energy time-shift, renewable capacity firming, and transmission and distribution upgrade deferral in the form of revenue or reduced cost and storage-related societal benefits such as integration of more renewables, reduced emissions and improved utilization of grid assets. A power-pool model which incorporates the one-sided auction market into POPF is developed. The model considers storage units as market participants submitting hourly price bids in the form of marginal costs. This provides an accurate market-clearing process as compared to the 'price-taker' analysis available in the literature where the effects of large-scale storage units on the market-clearing prices are neglected. Different case studies are provided to

Although research conducted within the military has assessed the health and mental health problems of military personnel, little information exists about personnel who seek care outside the military. The purpose of this study is to clarify the personal characteristics, mental health diagnoses, and experiences of active duty U.S. military personnel who sought civilian sector services due to unmet needs for care. This prospective, multi-method study included 233 clients, based in the United States, Afghanistan, South Korea, and Germany, who obtained care between 2013 and 2016 from a nationwide network of volunteer civilian practitioners. A hotline organized by faith-based and peace organizations received calls from clients and referred them to the network when the clients described unmet needs for physical or mental health services. Intake and follow-up interviews at 2 wk and 2 mo after intake captured demographic characteristics, mental health diagnoses, and reasons for seeking civilian rather than military care. Non-parametric bootstrap regression analyses identified predictors of psychiatric disorders, suicidality, and absence without leave (AWOL). Qualitative analyses of clients' narratives clarified their experiences and reasons for seeking care. The research protocol has been reviewed and approved annually by the Institutional Review Board at the University of New Mexico. Depression (72%), post-traumatic stress disorder (62%), alcohol use disorder (27%), and panic disorder (25%) were the most common diagnoses. Forty-eight percent of clients reported suicidal ideation.

The versatility of drones is one of the strengths that have led to the rapid development of this technology, as they adapt relatively easily to new applications, presenting considerable advantages such as greater energy efficiency, longer life and a significant lower operation cost than manned systems. The current applications of the drones, in addition to the military, are very wide and varied. The nuclear industry represents an important area of opportunity for drones, mainly in response to radiological emergencies, since in this case there is a latent risk of the general population being exposed to high radiation doses. Drones can be used in environments with high chemical and radiological toxicity without endangering human lives. Some of the possible applications of the drones in a nuclear power plant are: perimeter surveillance in physical security, where equipped with a high definition camera can be used as support to physical security systems in general; visual inspection at sites, structures, equipment and pipelines, etc., as part of preventive maintenance in order to avoid the loss of material due to corrosion, oxidation, cracking, subsidence; the visual inspection through thermo-graphic images to be able to detect hot spots in some critical element; measurement and radiological mapping on surfaces to maintain monitoring of radiological safety at nuclear power plant facilities; the monitoring of environmental parameters and the Environmental Impact Assessment to obtain important information to determine the environmental impact of a given area; and accident support by providing information that allows staff to size the magnitude of the damage.

The definition of portable fuel cells, or micro fuel cells as they are often called, is usually that its nominal power is below 250 W. There are, however, several widely separated applications and technical challenges in the span up to 250 W. Portable fuel cells from 1-10 W have potential applications in hand held electronics, wireless sensors, wireless networks and less power demanding equipment for outdoor life such as bicycle lamps, head lamps etc. The technical challenges involved here are mainly about cost, miniaturizing, dealing with heat rejection/cooling, stability/life and the fuel cell infrastructure - how shall the user 'fill' his/her fuel cell? Medium-sized, portable fuel cells between 10-50 W have potential applications in portable military equipment, larger portable electronics such as DVD players, camcorders and laptops (both for direct power and for charging of integrated batteries), to operate rescue equipment and as reserve power, and to replace some stationary power (APU). Also in this area challenges lie in cost, miniaturizing and heat rejection. Larger portable fuel cells of 50-250 W can for example be used in military equipment for charging of batteries, in rescue equipment and medical treatments, in boats and mobile homes, in small electric vehicles (manned or unmanned) and for remote power. In this type of replacement products the cost aspect is important, e g for material and system components. In this technique survey report we have analysed in total 31 pure micro fuel cell companies. In addition, we have also studied 14 larger electronic companies active in the fuel cell development. The three main technologies for portable fuel cell systems are Proton Exchange Membrane Fuel Cells (PEMFC), Direct Methanol Fuel Cells (DMFC) and Solid Oxide Fuel Cells (SOFC), Micro fuel cells that have been sold and have been available on the market up till today have been of the PEMFC and DMFC type and have mainly been used, to a limited extent

Are Military and Medical Ethics Necessarily Incompatible? A Canadian Case Study.

Science.gov (United States)

Rochon, Christiane; Williams-Jones, Bryn

2016-12-01

Military physicians are often perceived to be in a position of 'dual loyalty' because they have responsibilities towards their patients but also towards their employer, the military institution. Further, they have to ascribe to and are bound by two distinct codes of ethics (i.e., medical and military), each with its own set of values and duties, that could at first glance be considered to be very different or even incompatible. How, then, can military physicians reconcile these two codes of ethics and their distinct professional/institutional values, and assume their responsibilities towards both their patients and the military institution? To clarify this situation, and to show how such a reconciliation might be possible, we compared the history and content of two national professional codes of ethics: the Defence Ethics of the Canadian Armed Forces and the Code of Ethics of the Canadian Medical Association. Interestingly, even if the medical code is more focused on duties and responsibility while the military code is more focused on core values and is supported by a comprehensive ethical training program, they also have many elements in common. Further, both are based on the same core values of loyalty and integrity, and they are broad in scope but are relatively flexible in application. While there are still important sources of tension between and limits within these two codes of ethics, there are fewer differences than may appear at first glance because the core values and principles of military and medical ethics are not so different.

The "Revolution" is a tree of secular life: The Jornal do Brasil and the invention of democracy and legality of civil-military coup and the military government (1964-1968.

Full Text Available The research intends to analyze the editorials published by “Jornal do Brasil” (representative of the great press during the military-civil coup until 1968. The objective is to understand the justification for the military civil coup and the military government considering the speech changes of this newspaper in regard to the everyday politics. As “Jornal do Brasil” defended the intervention into Goulart´s constitutional government, like the most of the press, it´s conjectured that it continued to support the military government. The newspaper stressed that democracy should be preserved through democracy institutions and legality and their continuity in association with the military power. Even saying that democracy wasn’t practiced in that context, “JB” stated that the military government had it as the objective of its acts. It has been noticed that in spite of a contradiction in the editorial opinion, which varies between joining and criticism, it is always willing to guide the government actions. Therefore, “Jornal do Brasil” helped the military group to legitimate themselves before society through legalistic democratic speeches, but also in many occasions accused the government pointing out the political farces, for example the Constitution of 1967 and the indirect election, or criticizing the governmental immobility reminding, in several moments, promises made in 1964 that were not fulfilled – these promises intended to benefit the social group to which the newspaper integrated and represented. In other words, it preserves the democratic speech but also elaborates the conception that an arbitrary regime could improve the democracy and the development of capitalism.

[Purpose] The aim of this study was to determine the acute effect temporal of a complex training protocol on 30 meter sprint times. A secondary objective was to evaluate the fatigue indexes of military athletes. [Subjects and Methods] Seven military athletes were the subjects of this study. The variables measured were times in 30-meter sprint, and average power and peak power of squats. The intervention session with complex training consisted of 4 sets of 5 repetitions at 30% 1RM + 4 repetitions at 60% 1RM + 3 repetitions of 30 meters with 120-second rests. For the statistical analysis repeated measures of ANOVA was used, and for the post hoc analysis, student's t-test was used. [Results] Times in 30 meter sprints showed a significant reduction between the control set and the four experimental sets, but the average power and peak power of squats did not show significant changes. [Conclusion] The results of the study show the acute positive effect of complex training, over time, in 30-meter sprint by military athletes. This effect is due to the post activation potentiation of the lower limbs' muscles in the 30 meters sprint.

Yalch, Matthew M; Hebenstreit, Claire L; Maguen, Shira

2018-05-01

Servicewomen exposed to traumatic stressors over the course of their military service are at increased risk of developing symptoms of substance use disorder (SUD) and posttraumatic stress (PTS). They are also at risk for exposure to military sexual assault (MSA), which is also associated with SUD and PTS symptomology. Research is unclear about the incremental contributions of different forms of traumatic stressors on co-occurring SUD and PTS symptomology. In this study we examined the independent and combined effects of MSA and other military stressors on SUD and PTS symptomology in a sample of female veterans (N=407). Results indicate that MSA and other military stressors exhibit incremental effects on SUD and PTS symptomology. Results further suggest that women exposed to both MSA and other military stressors are at increased risk for developing co-occurring SUD and PTSD. These findings extend previous research on comorbid SUD and PTSD, highlighting the cumulative effects of traumatic stressors on posttraumatic psychopathology, and have implications for future research and clinical practice with female veterans.

Patient satisfaction and loyalty among military healthcare beneficiaries enrolled in a managed care program.

Science.gov (United States)

Jennings, B M; Loan, L A

1999-11-01

A study was performed to evaluate military beneficiaries' motivation for choosing to change from a civilian managed care system to the military managed care system. Concerns about healthcare cost, quality, and access underpin major reform in military healthcare. The military health system (MHS) is implementing managed care through an initiative known as TRICARE. Patient choice and satisfaction are highly relevant to all healthcare delivery systems; they are being explored aggressively in the MHS as TRICARE evolves. This descriptive study was conducted using a telephone survey consisting of 63 items derived from four pre-existing instruments as well as five facility-specific questions and demographics. The population of interest targeted military beneficiaries on a TRICARE waiting list who, at the time of enrollment, indicated a desire to receive care at the military facility. Consumers were inclined to return to the military system because of loyalty. Also, this study provided evidence that staff courtesy is important to those who seek healthcare. Good quality and accessibility were verified as essential elements in sustaining a consumer's positive view of and attraction to a particular healthcare system. Cost was proven to be a less substantial factor of consumer decision making. Surveys such as this give healthcare providers more information about aspects of care, such as patient loyalty and interpersonal dynamics, that attract people to their healthcare delivery systems. For healthcare systems to thrive, consumer influence and the power of patient dissatisfaction must be understood.

Military Parents' Personal Technology Usage and Interest in e-Health Information for Obesity Prevention.

Science.gov (United States)

Jai, Tun-Min; McCool, Barent N; Reed, Debra B

2016-03-01

U.S. military families are experiencing high obesity rates similar to the civilian population. The Department of Defense's Military Health System (MHS) is one of the largest healthcare providers in the United States, serving approximately 9.2 million active duty service members, retirees, spouses, and children. The annual cost to the MHS for morbidities associated with being overweight exceeds $1 billion. The preschool age has been suggested as an opportune time to intervene for the prevention of obesity. Thus, this study investigated the current level of technology usage by military service member families and assessed their needs and interests in health/nutrition information. This needs assessment is crucial for researchers/educators to design further studies and intervention programs for obesity prevention in military families with young children. In total, 288 military parents (233 Army and 55 Air Force) at two military bases whose children were enrolled in military childcare centers in the southwestern United States participated in a Technology Usage in Military Family (TUMF) survey in 2013. Overall, both bases presented similar technology usage patterns in terms of computer and mobile device usage on the Internet. Air Force base parents had a slightly higher knowledge level of nutrition/health information than Army base parents. The TUMF survey suggested practical ways such as mobile applications/Web sites, social networks, games, etc., that health educators can use to disseminate nutrition/health information for obesity prevention among military families with young children.

Applications of high-temperature superconductors in power technology

International Nuclear Information System (INIS)

Hull, John R

2003-01-01

Since the discovery of the first high-temperature superconductors (HTSs) in the late 1980s, many materials and families of materials have been discovered that exhibit superconductivity at temperatures well above 20 K. Of these, several families of HTSs have been developed for use in electrical power applications. Demonstration of devices such as motors, generators, transmission lines, transformers, fault-current limiters, and flywheels in which HTSs and bulk HTSs have been used has proceeded to ever larger scales. First-generation wire, made from bismuth-based copper oxides, was used in many demonstrations. The rapid development of second-generation wire, made by depositing thin films of yttrium-based copper oxide on metallic substrates, is expected to further accelerate commercial applications. Bulk HTSs, in which large single-grain crystals are used as basic magnetic components, have also been developed and have potential for electrical power applications

Performance evaluation of a high power DC-DC boost converter for PV applications using SiC power devices

Science.gov (United States)

Almasoudi, Fahad M.; Alatawi, Khaled S.; Matin, Mohammad

2016-09-01

The development of Wide band gap (WBG) power devices has been attracted by many commercial companies to be available in the market because of their enormous advantages over the traditional Si power devices. An example of WBG material is SiC, which offers a number of advantages over Si material. For example, SiC has the ability of blocking higher voltages, reducing switching and conduction losses and supports high switching frequency. Consequently, SiC power devices have become the affordable choice for high frequency and power application. The goal of this paper is to study the performance of 4.5 kW, 200 kHz, 600V DC-DC boost converter operating in continuous conduction mode (CCM) for PV applications. The switching behavior and turn on and turn off losses of different switching power devices such as SiC MOSFET, SiC normally ON JFET and Si MOSFET are investigated and analyzed. Moreover, a detailed comparison is provided to show the overall efficiency of the DC-DC boost converter with different switching power devices. It is found that the efficiency of SiC power switching devices are higher than the efficiency of Si-based switching devices due to low switching and conduction losses when operating at high frequencies. According to the result, the performance of SiC switching power devices dominate the conventional Si power devices in terms of low losses, high efficiency and high power density. Accordingly, SiC power switching devices are more appropriate for PV applications where a converter of smaller size with high efficiency, and cost effective is required.

Artificial Intelligence Application in Power Generation Industry: Initial considerations

2016-03-01

With increased competitiveness in power generation industries, more resources are directed in optimizing plant operation, including fault detection and diagnosis. One of the most powerful tools in faults detection and diagnosis is artificial intelligence (AI). Faults should be detected early so correct mitigation measures can be taken, whilst false alarms should be eschewed to avoid unnecessary interruption and downtime. For the last few decades there has been major interest towards intelligent condition monitoring system (ICMS) application in power plant especially with AI development particularly in artificial neural network (ANN). ANN is based on quite simple principles, but takes advantage of their mathematical nature, non-linear iteration to demonstrate powerful problem solving ability. With massive possibility and room for improvement in AI, the inspiration for researching them are apparent, and literally, hundreds of papers have been published, discussing the findings of hybrid AI for condition monitoring purposes. In this paper, the studies of ANN and genetic algorithm (GA) application will be presented.

Military Versus Civilian Murder-Suicide.

Patton, Christina L; McNally, Matthew R; Fremouw, William J

2015-07-03

Previous studies have implicated significant differences between military members and civilians with regard to violent behavior, including suicide, domestic violence, and harm to others, but none have examined military murder-suicide. This study sought to determine whether there were meaningful differences between military and civilian murder-suicide perpetrators. Using data from the Center for Disease Control's (CDC) National Violent Death Reporting System (NVDRS), military (n = 259) and civilian (n = 259) murder-suicide perpetrators were compared on a number of demographic, psychological, and contextual factors using chi-square analyses. Logistic regression was used to determine which variables predicted membership to the military or civilian perpetrator groups. Military murder-suicide perpetrators were more likely to be older, have physical health problems, be currently or formerly married, less likely to abuse substances, and to exhibit significantly different motives than civilian perpetrators. Logistic regression revealed that membership to the military, rather than the civilian, perpetrator group was predicted by age, physical health problems, and declining heath motive-reflecting the significance of a more than 15-year difference in mean age between the two groups. Findings point to the need to tailor suicide risk assessments to include questions specific to murder-suicide, to assess attitudes toward murder-suicide, and to the importance of assessing suicide and violence risk in older adult military populations. © The Author(s) 2015.

Cermet-fueled reactors for multimegawatt space power applications

International Nuclear Information System (INIS)

Cowan, C.L.; Armijo, J.S.; Kruger, G.B.; Palmer, R.S.; Van Hoomisson, J.E.

1988-01-01

The cermet-fueled reactor has evolved as a potential power source for a broad range of multimegawatt space applications. In particular, the fast spectrum reactor concept can be used to deliver 10s of megawatts of electric power for continuous, long term, unattended operation, and 100s of megawatts of electric power for times exceeding several hundred seconds. The system can also be utilized with either a gas coolant in a Brayton power conversion cycle, or a liquid metal coolant in a Rankine power conversion cycle. Extensive testing of the cermet fuel element has demonstrated that the fuel is capable of operating at very high temperatures under repeated thermal cycling conditions, including transient conditions which approach the multimegawatt burst power requirements. The cermet fuel test performance is reviewed and an advanced cermet-fueled multimegawatt nuclear reactor is described in this paper

This paper reports that soon after Roentgen's discovery, physicians in the armed services of the major powers grasped the importance of x-ray sin military surgery. By May of 1896, radiographic examinations were being performed on Italian soldiers returning from the ill-fated Ethiopian campaign. Initially, radiographs were used for foreign body localization and the detection of fractures; later, a full range of diagnostic services was offered. The early challenges of obtaining x-ray examinations in the field - fragility of tubes and plates, mobility of machines and patients, and unpredictability of radiation dosage - became the basis for innovations that would fundamentally alter the daily practice of radiology in civilian life
