Algorithmic information content, Church-Turing thesis, physical entropy, and Maxwell's demon  

SciTech Connect

Measurements convert alternative possibilities of its potential outcomes into the definiteness of the record'' -- data describing the actual outcome. The resulting decrease of statistical entropy has been, since the inception of the Maxwell's demon, regarded as a threat to the second law of thermodynamics. For, when the statistical entropy is employed as the measure of the useful work which can be extracted from the system, its decrease by the information gathering actions of the observer would lead one to believe that, at least from the observer's viewpoint, the second law can be violated. I show that the decrease of ignorance does not necessarily lead to the lowering of disorder of the measured physical system. Measurements can only convert uncertainty (quantified by the statistical entropy) into randomness of the outcome (given by the algorithmic information content of the data). The ability to extract useful work is measured by physical entropy, which is equal to the sum of these two measures of disorder. So defined physical entropy is, on the average, constant in course of the measurements carried out by the observer on an equilibrium system. 27 refs., 6 figs.

Computing Beyond the Church-Turing Limit  

NASA Astrophysics Data System (ADS)

Dershowitz and Gurevich claim to have proven the Church-Turing theorem starting from a set of 4 reasonable postulates. (Bulletin of Symbolic Logic, vol. 14, num. 3, Sept. 2008, pg. 299) But their postulate II assumes fixed vocabulary. Humans, however, change their vocabulary words (and concepts) over time. My Asa H artificial intelligence also changes its vocabulary. (Trans. of the Kansas Acad. of Sci., vol. 109, no. 3/4, pg 159, 2006, www.bioone.org/archive/0022- 8443/109/3/pdf/i0022-8443-109-3-159.pdf) Their postulate I excludes nondeterministic transitions between states. I don't know how often humans flip a coin but my Asa H does employ random transitions under certain circumstances. Perhaps humans and Asa H go beyond the Church-Turing limit. (Trans. Kansas Acad. of Sci., 108, 3/4, pg. 169, 2005)

Dissipative Quantum Church-Turing Theorem  

NASA Astrophysics Data System (ADS)

We show that the time evolution of an open quantum system, described by a possibly time dependent Liouvillian, can be simulated by a unitary quantum circuit of a size scaling polynomially in the simulation time and the size of the system. An immediate consequence is that dissipative quantum computing is no more powerful than the unitary circuit model. Our result can be seen as a dissipative Church-Turing theorem, since it implies that under natural assumptions, such as weak coupling to an environment, the dynamics of an open quantum system can be simulated efficiently on a quantum computer. Formally, we introduce a Trotter decomposition for Liouvillian dynamics and give explicit error bounds. This constitutes a practical tool for numerical simulations, e.g., using matrix-product operators. We also demonstrate that most quantum states cannot be prepared efficiently.

Trace element contents of selected antarctic meteorites, 1. Ph.D. Thesis  

NASA Technical Reports Server (NTRS)

Data are reported for volatile/mobile Ag, As, Au, Bi, Cd, Co, Cs, Cu, Ga, In, Rb, Sb, Se, Te, T1 and Zn in exterior and/or interior samples of four Antarctic meteorites: 77005 (unique achondrite); 77257 (unreilite); 77278 (L3); 77299 (H3). Exterior samples reflect contamination and/or leaching by weathering but trace element (ppm-ppt) contents in interior samples seem reasonable for representatives of these rare meteoritic types. The 77005 achondrite seems related to shergottites; other samples extend compositional ranges previously known for their types. With suitable precautions, Antarctic meteorite finds yield trace element data as reliable as those obtained from previously known falls.

A study of reduced chromium content in a nickel-base superalloy via element substitution and rapid solidification processing. Ph.D. ThesisFinal Report  

NASA Technical Reports Server (NTRS)

A study of reduced chromium content in a nickel base superalloy via element substitution and rapid solidification processing was performed. The two elements used as partial substitutes for chromium were Si and Zr. The microstructure of conventionally solidified materials was characterized using microscopy techniques. These alloys were rapidly solidified using the chill block melt spinning technique and the rapidly solidified microstructures were characterized using electron microscopy. The spinning technique and the rapidly solidified microstructures was assessed following heat treatments at 1033 and 1272 K. Rapidly solidified material of three alloys was reduced to particulate form and consolidated using hot isostatic pressing (HIP). The consolidated materials were also characterized using microscopy techniques. In order to evaluate the relative strengths of the consolidated alloys, compression tests were performed at room temperature and 1033 K on samples of as-HIPed and HIPed plus solution treated material. Yield strength, porosity, and oxidation resistance characteristics are given and compared.

Baruch Plan revisited. Master's thesis  

SciTech Connect

The primary concern in world politics is the proliferation of nuclear weapons. With the end of the Cold War, and dramatic democratic changes in Eastern Europe, many experts believe that international control of nuclear weapons is possible. This thesis examines the Baruch Plan as a model for international control of nuclear weapons. In doing so, this thesis outlines the original plan and details the initial criticism. The International Atomic Energy Agency is examined for its capability in the areas of inspections and verification. The enforcement capability of the United Nations is also discussed. This thesis concludes that the political climate is favorable for such dramatic changes however, the organizations which would be responsible for the maintenance of the system, namely the IAEA and the United Nations are not yet ready to assume their role.

This thesis discusses three basic concepts of economic analysis: the time value of money, life cycle cost, and reliability theory. Using these concepts, a method of economic analysis is developed to be used in evaluating the possible replacement of internal combustion engine (ICE) vehicles with electric vehicles (EVs). This methodology is then demonstrated by comparing two possible alternatives for replacement of the existing fleet of pickup trucks assigned to the 4950th Test Wing Aircraft Maintenance Complex at Wright-Patterson AFB, Ohio. One alternative is to replace the existing pickup fleet with new ICE pickups, the other is to replace the existing fleet with EVs. In this research effort the ICE pickup fleet is found to be the low cost alternative. Recommendations for further research and additional considerations are provided to the reader. This thesis contains an extensive bibliography on EV technology and principles of economic analysis.

Beyond Armageddon: Deterrence with less. Master's thesis  

SciTech Connect

This thesis examines the implications for nuclear deterrence between the United States and the Soviet Union brought about by the dramatic changes in the strategic environment during the 1980s. Specifically, it examines the potential for a new criteria of deterrence at significantly lower levels of strategic weapons. The analysis indicates that a targeting strategy which emphasizes economic and industrial facilities will deter the Soviet Union. This targeting strategy allows for a reduction to 1500 strategic weapons while maintaining the robustness of nuclear deterrence between the United States and the Soviet Union. Using as its criteria arms race stability, breakout stability, crisis stability, verification, predictability, consequences of war, and the security of friends and allies, this thesis concludes that a force structure comprised of the Trident D-5 Submarine-launched ballistic missile and the B-2 bomber best ensures deterrence both against the Soviet Union and any other nuclear power regardless of changes in their political or ideological orientation. To provide maximum flexibility while negotiating the agreement and to hedge against a breakdown in U.S/Soviet relations prior to implementation, the thesis recommends a modernization program for U.S. strategic forces including funding for the restructured Strategic Defense Initiative which is now named Global Protection Against Limited Strikes.

Single link flexible beam testbed project. Thesis  

NASA Technical Reports Server (NTRS)

This thesis describes the single link flexible beam testbed at the CLaMS laboratory in terms of its hardware, software, and linear model, and presents two controllers, each including a hub angle proportional-derivative (PD) feedback compensator and one augmented by a second static gain full state feedback loop, based upon a synthesized strictly positive real (SPR) output, that increases specific flexible mode pole damping ratios w.r.t the PD only case and hence reduces unwanted residual oscillation effects. Restricting full state feedback gains so as to produce a SPR open loop transfer function ensures that the associated compensator has an infinite gain margin and a phase margin of at least (-90, 90) degrees. Both experimental and simulation data are evaluated in order to compare some different observer performance when applied to the real testbed and to the linear model when uncompensated flexible modes are included.

Stringent and efficient assessment of boson-sampling devices.  

PubMed

Boson sampling holds the potential to experimentally falsify the extended Church-Turing thesis. The computational hardness of boson sampling, however, complicates the certification that an experimental device yields correct results in the regime in which it outmatches classical computers. To certify a boson sampler, one needs to verify quantum predictions and rule out models that yield these predictions without true many-boson interference. We show that a semiclassical model for many-boson propagation reproduces coarse-grained observables that are proposed as witnesses of boson sampling. A test based on Fourier matrices is demonstrated to falsify physically plausible alternatives to coherent many-boson propagation. PMID:25062152

Functional Programming (FP) sup BAC87 is an alternative to conventional imperative programming languages. This thesis describes an FP interpreter implementation. Superficially, FP appears to be a simple, but very inefficient language. Its simplicity, however, allows it to be interpreted quickly. Much of the inefficiency can be removed by simple interpreter techniques. This thesis describes the Illinois Functional Programming (IFP) interpreter, an interactive functional programming implementation which runs under both MS-DOS and UNIX. The IFP interpreter allows functions to be created, executed, and debugged in an environment very similar to UNIX. IFP's speed is competitive with other interpreted languages such as BASIC.

A matrix safety frame approach to robot safety for space applications. Thesis  

NASA Technical Reports Server (NTRS)

The planned use of autonomous robots in space applications has generated many new safety problems. This thesis assesses safety of autonomous robot systems through the structure of a proposed three-dimensional matrix safety frame. By identifying the common points of accidents and fatalities involving terrestrial robots, reviewing terrestrial robot safety standards, and modifying and extending these results to space applications, hazards are identified and their associated risks assessed. Three components of the safeguarding dimension of the matrix safety frame, safeguarding through design and operation for intrinsic safety, and incorporation of add-on safety systems are explained through examples for both terrestrial and space robots. A space robot hazard identification checklist, a qualitative tool for robot systems designers, is developed using the structure imparted by the matrix safety frame. The development of an expert system from the contents of the checklist is discussed.

Strategic planning, Polaris, and Tomahawk: technological imperative hypotheses. Master's thesis

This thesis examines the force procurement element of the military strategic planning process and is comprised of two parts. First, models are constructed to depict ideal strategic planning. The initial step in each model is the formulation of the national interest. The national interest is defined in terms useful to strategic planners by creating a unique paradigm based on the Constitution. The technological imperative hypothesis is explored as an aberration to the ideal strategic planning process. Second, the technological imperative hypothesis is tested with case studies of the Polaris and the Tomahawk. Even though the hypothesis was disproved in each case, the case studies yielded useful relationships between technology, strategy, and doctrine.

Nursing the future: a re-examination of the professionalization thesis in the light of some recent developments.  

PubMed

It is now 6 years since Salvage's (1988) analysis of the position of nursing within the professionalization process; this was written in the light of the aspirations of Project 2000. Recently there have been several significant policy statements from the United Kingdom Central Council which appear to be pursuing professional status despite Salvage's contention that nursing's leaders know 'that full professional status for nursing cannot be achieved'. Elements of these statements are discussed in relation to the professionalization thesis. Using the examples of nurse prescribing and managerialism, it is argued that the deprofessionalization thesis is more appropriate to nursing since the ideals of autonomy, authority and status are being eroded in the new managerialist post-Griffiths National Health Service culture. A positive deprofessionalization notion is put forward which highlights and re-emphasizes the caring role through the new occupational strategy of Assessment of Prior Experiential Learning (APEL).

TCP Packet Trace Analysis. M.S. Thesis  

NASA Technical Reports Server (NTRS)

Examination of a trace of packets collected from the network is often the only method available for diagnosing protocol performance problems in computer networks. This thesis explores the use of packet traces to diagnose performance problems of the transport protocol TCP. Unfortunately, manual examination of these traces can be so tedious that effective analysis is not possible. The primary contribution of this thesis is a graphical method of displaying the packet trace which greatly reduce, the tediousness of examining a packet trace. The graphical method is demonstrated by the examination of some packet traces of typical TCP connections. The performance of two different implementations of TCP sending data across a particular network path is compared. Traces many thousands of packets long are used to demonstrate how effectively the graphical method simplifies examination of long complicated traces. In the comparison of the two TCP implementations, the burstiness of the TCP transmitter appeared to be related to the achieved throughput. A method of quantifying this burstiness is presented and its possible relevance to understanding the performance of TCP is discussed.

Understanding the economic power of oil. Master's thesis  

SciTech Connect

Oil has become a single global market in which oil price fluctuations now have the ability to rock the world economy. The purpose of this thesis is to examine the changing nature of this threat and by doing so, show that Saudi Arabia, which has acted as the primary stabilizing tool by American foreign policy makers, will no longer suffice in this capacity. Rather, Saudi Arabia, which has for the most part cooperated with the United States in helping to stabilize oil price and supply disruptions, will become increasingly less cooperative in a much shorter time frame than night be anticipated with regard to oil supplies. This thesis proposes possible avenues for US national security policy by exploring pathways that might further ensure economic security and stability of the Middle East region in light of the new nature of the oil threat. The goal of economic security and stability can only be realized through an understanding of the oil producing nations and their relationships with the international community and world economy....

The polarizability of diatomic helium. Ph.D. Thesis  

NASA Technical Reports Server (NTRS)

The calculation of the electric dipole polarizability tensor of the He 2 dimer is described, and the results are used in the computation of several dielectric and optical properties of helium gas, at both high (322 K) and low (4 K) temperatures. The properties considered are the second dielectric virial coefficient, the second Kerr virial coefficient, and the depolarization ratio of the integrated intensities for the Raman scattering experiments. The thesis consists of five parts: the polarizability and various properties are defined; the calculation of the polarizability in the long-range region in terms of a quantum mechanical multipole expansion is described; the calculation of the He2 polarizability in the overlap region via coupled Hartree-Fock perturbation theory is described; the calculation of the quantum pair distribution function for both the He-3 and He-4 isotopes at 4 K is discussed; and the calculated values of the properties of helium gas are given.

Models for proliferation interdiction response analysis. Master`s thesis  

SciTech Connect

The proliferation of nuclear weapons poses a serious threat to the United States, its allies, and over-all world security. The United States seeks to dissuade or prevent new countries from acquiring nuclear weapons capabilities. This thesis constructs two models to aid decision makers in selecting strategies to interdict these proliferation efforts. The first, a what-if PERT/CPM model, provides an overall picture of the proliferation process. The graphical display is used to select activities to interdict, and to analyze the outcome of the choices. The second, an optimal interdiction model, selects the optimal activity(ies) or interdiction subject to risk constraints. Several runs with different numbers of interdiction points were made to test the optimal interdiction model. These results are further analyzed with the aid of the PERT/CPM model. The models, when used together, prove to be useful in selecting the optimal activities to interdict in the proliferation process.

Alternative propulsion plant for naval auxiliary ships. Master's thesis  

SciTech Connect

Due to the rising fuel cost, marine engineers and ship operators alike are searching for more fuel efficient propulsion plants to power ocean-going vessels. This thesis describes an alternative propulsion plant for the U.S. Navy's newest fleet oiler, the AO-177, in order to solve the problem of rising fuel costs. An analysis of converting the present geared steam turbine propulsion plant is performed, and the economic benefits of such a conversion are examined. The results of this analysis show that it is feasible to convert the AO-177 class fleet oiler to a diesel powered vessel provided that the conversion is performed prior to the end of the ship's third year of life. Two candidate diesel plants were studied with the most economical plant being selected for use in the conversion.

Energy management and control system verification study. Master's thesis  

SciTech Connect

Energy Management and Control Systems (EMCS) are being installed and operated throughout the Air Force. Millions of dollars have been spent on EMCS, but no study has conclusively proved that EMCS has actually saved the Air Force energy. This thesis used the Regression subprogram of Statistical Packages for the Social Sciences (SPSS) to determine if these systems are indeed saving the Air Force energy. Previous studies have shown that Multiple Linear Regression (MLR) is the best statistical predictor of base energy consumption. Eight bases were selected that had an operational EMCS. Two EMCS bases were compared with one control base for each of four CONUS winter heating zones. The results indicated small (less than 2%) energy savings have occurred at half of the EMCS bases studied. Therefore, this study does not conclusively prove that EMCS's have saved energy on Air Force bases. However, the methodology developed in this report could be applied on a broader scale to develop a more conclusive result.

Economic model for seaborne oil trade. Master`s thesis  

SciTech Connect

This thesis aims to provide some insights as to how oil prices and oil flows might vary with the carrying capacity of the tanker fleet as affected by political events. It provides an econometric analysis of tanker freight rates in the modern era and proposes a mathematical (quadratic) programming economic model that links the crude oil market to the supply elasticity of the world oil tanker fleet based on a competitive economy. The economic model can be considered as a version of the Walras-Cassel general-equilibrium system which possesses an economically meaningful equilibrium solution in terms of oil prices, freight rates and the pattern of oil distribution. The implementation of the model is completed using the General Algebraic Modeling System (GAMS). The study concludes with a scenario study showing how the model could be used to examine the importance of South East Asia`s sealanes in world seaborne oil trade. The model shows the economic vulnerability of oil importing nations, especially Japan, the United States, and Western Europe, to a possible closure of South East Asian sealanes.

Chinese tactical nuclear weapons. Master`s thesis  

SciTech Connect

The United States, Russia and Great Britain have retired all nonstrategic nuclear weapons. Surprisingly, China has not, China seems to value highly tactical nuclear weapons (TNWs). Most studies of China`s nuclear arsenal focus on strategic nuclear weapons. This focus could mislead those trying to understand PRC TNW strategy. The purpose of this thesis is to explain China`s TNW development. China`s nuclear arsenal evolution can be described in three phases. In the first phase, China developed a limited strategic nuclear deterrent. China`s arsenal was driven by threat. Technology supplanted threat as the dominant driver during the next phase. While conducting research to miniaturize strategic warheads, were developed. During the third phase, a reduced threat caused political leaders to restrain the nuclear program. The nuclear program reverted to its primary objective - building strategic weapons, causing TNW production to level off. This study explains the last two phases of TNW development. The research goals are twofold: to compare threat and technology, the primary motivations driving TNW production; and to examine the relationship between doctrine and development, describing how one influences the other. The conclusion offers U.S. foreign policy recommendations.

Soviet concepts of ballistic missile defense. Master's thesis  

SciTech Connect

This thesis characterizes the Soviet concept of ballistic missile defense (BMD) in order to better understand and predict future Soviet BMD decision making. The Soviet concept of BMD is fundamentally different from that in the West. Soviet BMD is clearly an integral component of a much larger Soviet strategic defense effort which consists of strategic air defense as well as passive measures, such as mobility, deep underground command and control facilities, and civil defense. As the Soviet military literature demonstrates, Soviet strategic air defense encompasses defense against a continuum of threats -- from aircraft to ballistic missiles to satellites to 'space-strike weapons'. Soviet strategic air defense weapons therefore appear optimized to counter a wide range of airborne threats. In the Soviet view, surface-to-air missiles may be a primary tactical BMD weapon. Additionally, Soviet strategic BMD weapons may be a primary Soviet anti-satellite weapon. Furthermore, manned space platforms play a particularly significant role in Soviet thinking about the future of BMD and space warfare.

Geodetic measurement of deformation in California. Ph.D. Thesis  

NASA Technical Reports Server (NTRS)

The very long baseline interferometry (VLBI) measurements made in the western U.S. since 1979 as part of the NASA Crustal Dynamics Project provide discrete samples of the temporal and spatial deformation field. The interpretation of the VLBI-derived rates of deformation requires an examination of geologic information and more densely sampled ground-based geodetic data. In the first two of three related studies embodying this thesis triangulation and trilateration data measured on two regional networks are processed, one in the central Mojave Desert and one in the Coast Ranges east of the San Andreas fault. At the spatial scales spanned by these local geodetic networks, auxiliary geologic and geophysical data have been utilized to examine the relation between measured incremental strain and the accommodation of strain seen in local geological structures, strain release in earthquakes, and principal stress directions inferred from in situ measurements. In the third study, VLBI data from stations distributed across the Pacific - North American plate boundary zone in the western United States are processed. The VLBI data have been used to constrain the integrated rate of deformation across portions of the continental plate boundary in California and to provide a tectonic framework to interpret regional geodetic and geologic studies.

Thermal effects on a rotating missile. Master's thesis  

SciTech Connect

This thesis sought to determine if rotation would decrease the maximum skin temperature of an ICBM, thus increasing its probability of survival. The first scenario investigated was the Peacekeeper Dense Pack system. The missile field was subjected to a walk attack of 2 MAT weapons, with incoming RV's exploding every two secs. The 2nd scenario was a 4-on-1 attack of a missile-launching system--specifically, one missile was subjected to four bursts located in various positions surrounding the missile. Finally, a missile is attacked by a space-based laser with a maximum absolute power of 10 megawatts. In all cases, the rotation rate was limited to a maximum of 1.6 radians/sec. In all scenarios studied, rotation significantly decreased the maximum skin temperature and increased the missile's probability of survival. The decrease was most dramatic for the walk attack where an optimum rotation rate of .8 radians/sec was established. For the 4-on-1 attack, rotation was effective but required the maximum 1.6 radians/sec rotation rate for best results. For the laser threat rotation was effective, with the maximum rotation rate providing the greatest amount of protection.

Nozzle Flow with Vibrational Nonequilibrium. Ph.D. Thesis  

NASA Technical Reports Server (NTRS)

Flow of nitrogen gas through a converging-diverging nozzle is simulated. The flow is modeled using the Navier-Stokes equations that have been modified for vibrational nonequilibrium. The energy equation is replaced by two equations. One equation accounts for energy effects due to the translational and rotational degrees of freedom, and the other accounts for the affects due to the vibrational degree of freedom. The energy equations are coupled by a relaxation time which measures the time required for the vibrational energy component to equilibrate with the translational and rotational energy components. An improved relaxation time is used in this thesis. The equations are solved numerically using the Steger-Warming flux vector splitting method and the Implicit MacCormack method. The results show that uniform flow is produced outside of the boundary layer. Nonequilibrium exists in both the converging and diverging nozzle sections. The boundary layer region is characterized by a marked increase in translational-rotational temperature. The vibrational temperature remains frozen downstream of the nozzle, except in the boundary layer.

Global lightning activity and climate change. Ph.D. Thesis  

SciTech Connect

The relationship between global lightning frequencies and global climate change is examined in this thesis. In order to study global impacts of climate change, global climate models or General Circulations Models (GCM`s) need to be utilized. Since these models have coarse resolutions many atmospheric phenomena that occur at subgrid scales, such as lightning, need to be parameterized whenever possible. The first chapter introduces a simple parameterization used to simulate total (intracloud and cloud-to-ground) lightning frequencies. The parameterization uses convective cloud top height to approximate lightning frequencies. The second chapter deals with a parameterization for simulating cloud-to-ground (CG) lightning around the globe. This parameterization uses the thickness of the cold cloud sector in thunderstorms (0 C to cloud top) to calculate the proportion of CG flashes in a particular thunderstorm. The third chapter deals with the modelling of lightning in the Goddard Institute for Space Studies (GISS) GCM. This chapter presents results from the model`s control run. The fourth chapter presents two climate change scenarios. One for a climate where the solar constant is reduced by 2% (5.9 C global cooling), and one for a climate with twice the present concentration of CO2 in the atmosphere (4.2 C global warming). The results imply a 24% / 30% decrease/increase in global lightning frequencies for the cooler/warmer climate. The fifth chapter considers the possibility of using the above findings to monitor future global warming. The results show that the earth`s ionospheric potential, which is regulated by global thunderstorm activity, could possibly supply valuable information regarding global surface temperature fluctuations. The sixth and final chapter looks at the implications of changes in both lightning frequencies and the hydrological cycle, as a result of global warming, on natural forest fires.

Toward a more effective Japan policy. Master`s thesis  

SciTech Connect

The United States and Japan have shared a close relationship since the end of World War 2. What began as a victor- and-vanquished relationship was transformed into one of the Cold War`s pillars of Containment. Now the Cold War is over yet the United States remains responsible for the external defense of the state that possesses the world`s second most powerful economy. Simultaneously, Japan is attempting to end its tradition of political isolationism. As Japan exercises ever increasing autonomy and less deference to U.S. policy and desires, the administration, congress, and American public are searching for the elusive peace dividend. Should Japan continue to progress toward the ultimate goal of normal nation status, those animosities now present primarily in the trade realm may spill-over into the political and security arenas. Additionally, the 1 August 1994 edition of the Mainichi Shimbun reported that the Japanese Foreign Ministry secretly decided, in 1969, to develop the potential to make nuclear weapons without actually producing them. The same report indicated that the potential had been met. Now another complication to the relationship has emerged. While it is understandable for Japan to desire an indigenous nuclear deterrent capability, Japan`s status as a virtual proliferator runs contrary to U.S. nonproliferation policy. This thesis explores the future of the United States-Japan relationship considering the current international environment -- a seemingly absent raison d`ene. Recommendations for a revised Japan policy including an innovative approach to allied nuclear proliferation are presented.

Development and applications of ionospheric tomography. Ph.D. Thesis  

SciTech Connect

Recently, several tomographic techniques for ionospheric electron density imaging have been proposed. These techniques reconstruct a vertical slice image of electron density using total electron content data. The data are measured between a low orbit beacon satellite and fixed receivers located along the projected orbital path of the satellite. By using such tomographic techniques, it may be possible to inexpensively (relative to incoherent scatter techniques) image the ionospheric electron density in a vertical plane several times per day. The satellite and receiver geometry used to measure the total electron content data causes the data to be incomplete; that is, the measured data do not contain enough information to completely specify the ionospheric electron density distribution in the region between the satellite and the receivers. A new algorithm is proposed which allows the incorporation of other complementary measurements, such as those from ionosondes, and also includes ways to include a priori information about the unknown electron density distribution in the reconstruction process. The algorithm makes use of two-dimensional basis functions. Illustrative application of this algorithm is made to simulated cases with good results. The technique is also applied to real total electron content (TEC) records collected in Scandinavia in conjunction with the EISCAT incoherent scatter radar. The tomographic reconstructions are compared with the incoherent scatter electron density images of the same region of the ionosphere.

Thermal Stability of Distillate Hydrocarbon Fuels. Ph.D. Thesis  

NASA Technical Reports Server (NTRS)

Thermal stability of fuels is expected to become a severe problem in the future due to the anticipated use of broadened specification and alternative fuels. Future fuels will have higher contents of heteroatomic species which are reactive constituents and are known to influence fuel degradation. To study the degradation chemistry of selected model fuels, n-dodecane and n-dodecane plus heteroatoms were aerated by bubbling air through the fuels amd stressed on a modified Jet Fuel Thermal Oxidation Tester facility operating at heater tube temperatures between 200 to 400 C. The resulting samples were fractionated to concentrate the soluble products and then analyzed using gas chromatographic and mass spectrometric techniques to quantify and identify the stable reaction intermediate and product specifically. Heteroatom addition showed that the major soluble products were always the same, with and without heteroatoms, but their distributions varied considerably.

Content identification: binary content fingerprinting versus binary content encoding  

NASA Astrophysics Data System (ADS)

In this work, we address the problem of content identification. We consider content identification as a special case of multiclass classification. The conventional approach towards identification is based on content fingerprinting where a short binary content description known as a fingerprint is extracted from the content. We propose an alternative solution based on elements of machine learning theory and digital communications. Similar to binary content fingerprinting, binary content representation is generated based on a set of trained binary classifiers. We consider several training/encoding strategies and demonstrate that the proposed system can achieve the upper theoretical performance limits of content identification. The experimental results were carried out both on a synthetic dataset with different parameters and the FAMOS dataset of microstructures from consumer packages.

This study investigated the application of National Environmental Policy Act (NEPA) requirements to Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) actions. Similarities in the documentation and public participation requirements of NEPA and CERCLA include identification and evaluation of alternatives and public participation. Differences include document contents and timing of public participation. This study presented four options for ensuring NEPA compliance at CERCLA sites. Option one included a Programmatic Environmental Impact Statement (PEIS) with subsequent combined FS/EIS report for each subunit. Option two eliminated the PEIS, but retained a stand-alone NEPA document for each CERCLA subunit. Option three included a PEIS with a subsequent combined FS/EIS report for each subunit. Option four eliminated the PEIS but retained a combined FS/EIS report for each subunit. The model presented in this study can be used at any installation to determine the optimal approach for the site. The model's goal is to comply with NEPA and CERCLA while maintaining a balance between cost, schedule, and public acceptance.

Cadmium and lead in biomedical waste incinerators. Master's thesis  

SciTech Connect

The California Air Resources Board (CARB) has reported relatively high concentrations of cadmium and lead in recent tests of Bio-Medical Waste Incinerators (BMWI) in California. Cadmium and lead have been observed in the stack gas of incinerators before application of controls. Both metals appear to have been enriched in the fly ash. Sources of cadmium and lead in BMMWIs were investigated. Based on a review of the literature, compounds of cadmium and lead are used as heat and light stabilizers, and as pigments in various plastics, particularly in polyvinyl chlorides (PVC). The high HCI content of stack gases indicates a significant fraction of the waste stream contains chlorinated plastics. In samples analyzed from a hospital waste stream lead was found in several plastic items, as well as in paper packaging material. A source of cadmium was not positively identified, however, it appeared to be present in the casing of an alkaline battery. Both metals may also be present in inks, metallic items (needles, scalpels, etc), paper products, and paints. However, there was no evidence from which could be concluded that such items contributed to the observed levels of cadmium and lead. If sources of cadmium and lead can be identified, hospital administrators may be able to reduce or eliminate metal emissions by pressuring industry to change the composition of the source materials or by limiting their introduction into the incinerator waste stream.

Russian military in the year 2000. Master's thesis  

SciTech Connect

Through the use of content analysis, this paper attempts to paint a picture of the Russian military in the year 2000 and its impact on the US national security strategy. The research begins by defining the origin of Russian national security policy and how that translates into military policy and doctrine. A framework for evaluating Russian military doctrines is provided with a chronology of the military reform process and the related doctrinal reforms that has its birth in the 1987 announcement of a defensive-defense. Following from the doctrinal variant framework the new strategic missions of the 1992 draft military doctrine are presented with an analysis that shows they are a clear departure from the past and truly represent a defensive-defense type doctrine. Additionally, a comparison is made with the current military reform ongoing in Russia with the historical precedent of the Russian military reform of 1924-25. A rough outline of the separate branches of the Russian military both present and future is provided based on the ongoing trends in the reform process. This thumbnail sketch of the Russian military then assists in the analysis and conclusion that even after a possible 50% cutback in US military spending, in the year 2000 the Russian military will not pose a threat to US national security. The major caveat to this conclusion is in the realm of nuclear weapons and this issue is therefore discussed in some length....Former Soviet Union, Russia, Commonwealth of Independent States (CIS), Conventional Forces in Europe treaty (CFE), European Security, New National Security Strategy, Nuclear Weapons, Nuclear Strategy.

We examine whether Stephen Sandford's (2006b) ‘too many people, too few livestock’ thesis for the Greater Horn of Africa applies to West Africa. In a comparative study of seven pastoral systems across West Africa we found that pastoralists have generally successfully adapted to pressures on grazing resources. We describe three adaptive strategies: 1) integration and intensification in the Sudanian zone;

Naturalising Representational Content  

PubMed Central

This paper sets out a view about the explanatory role of representational content and advocates one approach to naturalising content – to giving a naturalistic account of what makes an entity a representation and in virtue of what it has the content it does. It argues for pluralism about the metaphysics of content and suggests that a good strategy is to ask the content question with respect to a variety of predictively successful information processing models in experimental psychology and cognitive neuroscience; and hence that data from psychology and cognitive neuroscience should play a greater role in theorising about the nature of content. Finally, the contours of the view are illustrated by drawing out and defending a surprising consequence: that individuation of vehicles of content is partly externalist.

Soviet political objectives in the Federal Republic of Germany: instruments and assessments. Master's thesis  

SciTech Connect

This thesis examines apparent Soviet attempts to use its detente policy to exploit the Federal Republic of Germany's membership in NATO and thereby expand its influence in the FRG and Europe as a whole. It is hypothesized that the Soviet Union chooses to exploit the FRG's position in NATO by cultivating a special relationship with it and thereby accessing the U.S. and NATO as a whole, rather than making overt efforts to force a near-term split between West Germany and the U.S. The thesis focuses on the instruments the Soviet Union uses to maximize its influence in the FRG and the region. These instruments include West Germany's concerns regarding nuclear war in Europe, Ostpolitik and German-German relations.

Canada: the decision to procure nuclear-attack submarines and its significance for NATO. Master's thesis  

SciTech Connect

In June 1987 the Canadian government announced plans to procure 10 to 12 nuclear attack submarines (SSNs). The evidence suggests that, for some Canadians, a primary purpose for this submarine program may not be to enhance the security of NATO, but instead to assert Canada's sovereignty, principally against the United States, in the Arctic region. The thesis discusses this decision and its possible implications for the security of North America and NATO. It is argued that the United States must continue to have unimpeded access to the Arctic region to counter the ever-increasing threat posed by Soviet nuclear ballistic missile submarines (SSBNs). Finally, the thesis suggests a possible solution to the current sovereignty debate and a potential strategy for employing these SNN to enhance the security of North America and NATO as a whole.

Protestant Clergy and the Culture Wats: An Empirical Test of Hunter's Thesis  

PubMed Central

This study instead focuses on culture wars among religious elites—clergy—and tests three aspects of the culture wars thesis: (1) whether cultural wars exist at all among religious elites, (2) whether clergy attitudes are polarized on these issues, and (3) whether religious authority or religious affiliation is more salient in creating culture wars cleavages. Using data from a large random sample of Protestant clergy, we find a substantial amount of engagement in culture wars by all types of Protestant clergy. The amount of polarization is more attributable to views of religious authority (i.e., biblical inerrancy) than to religious tradition. Moreover, polarization among clergy is somewhat more evident on culture wars issues than on other social and political issues. These findings are generally supportive of the culture wars thesis and should help return examinations of culture wars back to where they were originally theorized to be waged: among elites.

Two arm robot path planning in a static environment using polytopes and string stretching. Thesis  

NASA Technical Reports Server (NTRS)

The two arm robot path planning problem has been analyzed and reduced into components to be simplified. This thesis examines one component in which two Puma-560 robot arms are simultaneously holding a single object. The problem is to find a path between two points around obstacles which is relatively fast and minimizes the distance. The thesis involves creating a structure on which to form an advanced path planning algorithm which could ideally find the optimum path. An actual path planning method is implemented which is simple though effective in most common situations. Given the limits of computer technology, a 'good' path is currently found. Objects in the workspace are modeled with polytopes. These are used because they can be used for rapid collision detection and still provide a representation which is adequate for path planning.

The pioneer woman's view of migraine: Elizabeth Garrett Anderson's thesis "Sur la migraine".  

PubMed

This is a presentation of a doctoral thesis of 1870. The author was English but the thesis and the examinations were in French. Elizabeth Garrett Anderson, usually referred to as E.G.A., was the first woman in Britain to obtain the title of M.D., but not the first in Europe. Nadeshda Prokofevna Suslova, a Russian, received her M.D. in 1867 in Zurich, the most liberal university at that time, soon to be flooded by female students from Russia. E.G.A. had been applying to the few possible European universities but she settled for Paris after the Empress Eugenie had decided that she should be accepted there. This meant that she could succeed without having to be a Paris resident, just by writing a thesis and passing a series of examinations presided over by Paul Broca. This was important as she was already conducting private and dispensary practice, and could not find a locum (she insisted on a woman). E.G.A. had suffered many setbacks, for being a woman, as such being unacceptable in dissection rooms and operating theatres, and generally in a professional career where women were unheard of. She was finally permitted to receive her medical diploma from the Worshipful Society of Apothecaries of London. She wrote about her thesis: "I have chosen Headache as its subject. I had to find a subject which could be well studied without post-mortem observations, of which I can have but very few in either private or dispensary practice; and I wished also to take a large subject, one that demanded some insight into the harmony that exists between the main physiological functions." Marcia Wilkinson (M.W.), who worked in the Elizabeth Garrett Anderson Hospital in London for 35 years, heard there of E.G.A.'s thesis on migraine and sent for it from Paris. In 1966 she translated it into English from the original French, being interested both in the subject and in the person of this resolute and lucid woman. When H. Isler found the French thesis in the British Library he intended to translate it but, after discussion, we decided on a joint effort (95% of the translation is by M.W.; very few details were changed, and some footnotes added for better understanding). We think that E.G.A.'s text is a classic, showing profound understanding, sound practical advice, and also, in its theoretical part, the limits of neurophysiological knowledge in Paris when Brown-Sequard was "charge des cours" there. We may add that in her various examinations she had to answer questions, in French, on the use of footprints by the police, the general nature of fishes, toxic fishes, electric fishes, cod liver oil, and the secretion of tears. She earned much applause from the public, which consisted of male French students, and the overt appreciation of Paul Broca, head examiner, and Dr Wurtz, the Dean of the Faculte de Médecine. The impact of her thesis in the 19th century was modest. It appears to be rather marginal in the German literature of the early 20th century, but it has imprinted the management of migraine at the City of London Migraine Clinic in the last thirty years. The importance of nutrition, regular meals, regular habits, the need to supplement analgesics with antiemetics, and the treatment of the attack with rest, and great quantities of hot tea, were certainly related to E.G.A.'s doctrine. The internationally prevailing recommendation to give antiemetics, and then only analgesics, as well as the combination of both in one tablet, may thus be traced back to E.G.A. via the teachings of M.W. and Nat Blau.

US Patent & Trademark Office Database

In a broadcast system (210) each broadcast content item is identified by a broadcast Content Reference Identifier (CRID). In a storage device (220) with a storage (240) each broadcast content item is identified by a local CRID. A processor (230) stores a CRID list that includes for CRIDs an associated validity interval including a starting date and an ending date during which interval the CRID is unique for the content item. When the processor receives (400) a broadcast CRID, it determines (410) an initial validity interval for the broadcast CRID. The initial validity interval includes a starting date and an ending date during which interval the broadcast CRID is unique for the broadcast content item. It then determines (420) whether the initial validity interval overlaps with a validity interval stored in the CRID list for an identical CRID. If there is no overlap it adds (430) the broadcast CRID to the CRID list.

A numerical study of fundamental shock noise mechanisms. Ph.D. Thesis - Cornell Univ.  

NASA Technical Reports Server (NTRS)

The results of this thesis demonstrate that direct numerical simulation can predict sound generation in unsteady aerodynamic flows containing shock waves. Shock waves can be significant sources of sound in high speed jet flows, on helicopter blades, and in supersonic combustion inlets. Direct computation of sound permits the prediction of noise levels in the preliminary design stage and can be used as a tool to focus experimental studies, thereby reducing cost and increasing the probability of a successfully quiet product in less time. This thesis reveals and investigates two mechanisms fundamental to sound generation by shocked flows: shock motion and shock deformation. Shock motion is modeled by the interaction of a sound wave with a shock. During the interaction, the shock wave begins to move and the sound pressure is amplified as the wave passes through the shock. The numerical approach presented in this thesis is validated by the comparison of results obtained in a quasi-one dimensional simulation with linear theory. Analysis of the perturbation energy demonstrated for the first time that acoustic energy is generated by the interaction. Shock deformation is investigated by the numerical simulation of a ring vortex interacting with a shock. This interaction models the passage of turbulent structures through the shock wave. The simulation demonstrates that both acoustic waves and contact surfaces are generated downstream during the interaction. Analysis demonstrates that the acoustic wave spreads cylindrically, that the sound intensity is highly directional, and that the sound pressure level increases significantly with increasing shock strength. The effect of shock strength on sound pressure level is consistent with experimental observations of shock noise, indicating that the interaction of a ring vortex with a shock wave correctly models a dominant mechanism of shock noise generation.

Concentration and content  

PubMed Central

One of the more frequent activities in health sciences is the measurement of biological quantities. Frequently, when reading biomedical books and journals some confusion on the metrological meaning of biological quantities related to the concepts ‘concentration’ and ‘content’ may be observed. Classically, a concentration is an amount of any type per volume of liquid or gas system, whereas content is an amount of any type per mass of liquid or gas or solid system. However the concepts ‘concentration’ and ‘content’ alone are still ambiguous because, depending on the type of amount of the component (analyte) per volume or mass of a system, there are different types of concentrations and contents. This article attempts to give a clarification of these concepts, mainly based on international recommendations about nomenclature and terminology of metrology, chemistry and clinical laboratory sciences.

Semantische Content Management Systeme  

NASA Astrophysics Data System (ADS)

Content Management Systeme (CMS) sind in vielen Organisationen bereits seit längerer Zeit fester Bestandteil zur Verwaltung und kollaborativen Bearbeitung von Text- und Multimedia-Inhalten. Im Zuge der rasch ansteigenden Fülle an Informationen und somit auch Wissen wird die Überschaubarkeit der Datenbestände jedoch massiv eingeschränkt. Diese und zusätzliche Anforderungen, wie automatisch Datenquellen aus dem World Wide Web (WWW) zu extrahieren, lassen traditionelle CMS immer mehr an ihre Grenzen stoßen. Dieser Beitrag diskutiert die neuen Herausforderungen an traditionelle CMS und bietet Lösungsvorschläge, wie CMS kombiniert mit semantischen Technologien diesen Herausforderungen begegnen können. Die Autoren stellen eine generische Systemarchitektur für Content Management Systeme vor, die einerseits Inhalte für das Semantic Web generieren, andererseits Content aus dem Web 2.0 syndizieren können und bei der Aufbereitung des Content den User mittels semantischer Technologien wie Reasoning oder Informationsextraktion unterstützen. Dabei wird auf Erfahrungen bei der prototypischen Implementierung von semantischer Technologie in ein bestehendes CMS System zurückgegriffen.

Want to Improve Undergraduate Thesis Writing? Engage Students and Their Faculty Readers in Scientific Peer Review  

PubMed Central

One of the best opportunities that undergraduates have to learn to write like a scientist is to write a thesis after participating in faculty-mentored undergraduate research. But developing writing skills doesn't happen automatically, and there are significant challenges associated with offering writing courses and with individualized mentoring. We present a hybrid model in which students have the structural support of a course plus the personalized benefits of working one-on-one with faculty. To optimize these one-on-one interactions, the course uses BioTAP, the Biology Thesis Assessment Protocol, to structure engagement in scientific peer review. By assessing theses written by students who took this course and comparable students who did not, we found that our approach not only improved student writing but also helped faculty members across the department—not only those teaching the course—to work more effectively and efficiently with student writers. Students who enrolled in this course were more likely to earn highest honors than students who only worked one-on-one with faculty. Further, students in the course scored significantly better on all higher-order writing and critical-thinking skills assessed.

Radiation and scattering from cylindrically conformal printed antennas. Ph.D. Thesis Final Report  

NASA Technical Reports Server (NTRS)

Microstrip patch antennas offer considerable advantages in terms of weight, aerodynamic drag, cost, flexibility, and observables over more conventional protruding antennas. These flat patch antennas were first proposed over thirty years ago by Deschamps in the United States and Gutton and Baisinot in France. Such antennas have been analyzed and developed for planar as well as curved platforms. However, the methods used in these designs employ gross approximations, suffer from extreme computational burden, or require expensive physical experiments. The goal of this thesis is to develop accurate and efficient numerical modeling techniques which represent actual antenna structures mounted on curved surfaces with a high degree of fidelity. In this thesis, the finite element method is extended to cavity-backed conformal antenna arrays embedded in a circular, metallic, infinite cylinder. Both the boundary integral and absorbing boundary mesh closure conditions will be used for terminating the mesh. These two approaches will be contrasted and used to study the scattering and radiation behavior of several useful antenna configurations. An important feature of this study will be to examine the effect of curvature and cavity size on the scattering and radiation properties of wraparound conformal antenna arrays.

[The thesis of judicialization of health care by the elites: medication for mucopolysaccharidosis].  

PubMed

This paper evaluates the hypothesis that the judicialization of medicine for mucopolysaccharidosis in Brazil is an action promoted by economic elites. Previous studies upholding the thesis of judicialization by elites in the case of other types of medication that are more costly for the Unified Health Service are discussed. An analysis of all 196 processes containing information about judicial processes brought to court between February 2006 and December 2010 that ended by determining that the State should provide such medication free of charge to patients was conducted. There is evidence that attorneys' fees were covered by entities interested in the results of judicialization, such as the distributors or pharmaceutical industries. Patients may also be migrating for diagnosis and treatment to university centers that are a benchmark for medical innovation in the country, as the option for public health services is related to their higher technical and scientific capacity. Therefore, the resort to private lawyers, indicators of social exclusion based on the address of patients and the use of public health services, are not adequate class information to corroborate or refute the thesis of judicialization by the elites.

Redesign and rehost of the BIG-STICK nuclear war-game simulation. Master's thesis  

SciTech Connect

The strategic nuclear wargame BIG STICK is a two-sided, interactive, computer simulation used by the Air Command and Staff College to assist students in learning about real-world nuclear war planning. Currently, the simulation is played on the Honeywell H6000 mainframe. Shortcomings of the simulation are the user-hostile environment, a rigid input format. The unforgiving and inflexible user interface, and the fixed file system that makes data changes and program enhancements difficult. The purpose of this thesis effort was to redesign and rehost the BIG STICK simulation to the Zenith Z-158 classroom microcomputers. Game sites, fixed and controlled force assets, expected value probabilities, and exercise constraints are now stored in a relational data base designed using the entity-relationship (E-R) model. The user interface was redesigned using general user-friendly program principles and guidelines to provide a screen-oriented environment for students to enter force selection, deployment, targeting, and employment inputs. Reports reflecting the results of student inputs were designed and developed as part of the interface using the PC INGRESS data-base-management system. The actual game-play portion of the simulation was designed using top-down, hierarchical decomposition. Implementation of the design into program code is not included in the scope of this thesis.

Deregulation of electric utilities in California and its effect on navy installations. Master`s thesis  

SciTech Connect

On January 1, 1998, California will be the first state to deregulate its electricity industry. Deregulation is expected to reduce the high rates paid throughout the state by allowing competition, not regulators, to determine rates. Deregulation will dissolve the monopoly of the electricity industry by allowing customers to choose who will supply their electricity. Competition will emerge in the generation market, where transactions between consumers and suppliers will be free and open. Under regulation, most customers do not have a choice in their electricity supplier. Their supplier is usually determined by their geographic location. This thesis researches the differences between the regulated and deregulated rate structures and provides a cost comparison for a Navy organization classified as a large commercial/industrial user of electricity. There are many aspects of deregulation that are not yet determined, but the initial comparison indicates deregulation may save Navy installations money. If deregulation progresses as planned, additional future saving may occur.

Vectorized hidden-surface algorithm implemented on the Cray-2 supercomputer. Master's thesis  

SciTech Connect

Recent developments in scientific computing have prompted the need for supercomputer graphics research. These developments include the requirement to visualize large amounts of data processed by the supercomputer, preferably by real-time image generation. Unfortunately, most currently used graphics algorithms are not optimized for vector computers. This thesis involves the design and implementation of a hidden-surface removal algorithm for the Cray-2 vector supercomputer, with the goal of real-time image display. A z-buffer hidden-surface algorithm, written in Pascal, was vectorized and implemented on the Cray-2. Special attention was directed toward the methodology of algorithm and data-structure design to exploit the Cray-2 architecture. Timing studies comparing the vector version to the equivalent scalar version showed that, while tha Pascal vector code produced localized speedups, the vector code was less efficient than the scalar code.

Origin and evolution of US Naval strategic nuclear policy to 1960. Master's thesis  

SciTech Connect

This thesis treats the impact of the atomic bomb on traditional naval strategy as that strategy had developed under the influence of Captain Alfred T. Mahan, how traditional naval strategy was modified by the development of naval aviation, the lessons of World War II, and the leadership of James Forrestal, and how the adoption of atomic weapons into naval strategic planning was integrally tied to naval aviation. The growth of the Soviet Union as a threat to world peace, and interservice rivalry over roles and missions are compared as factors that influenced the development of post-World War II naval strategic thinking. The Navy's reaction to the adoption of massive retaliation as the foundation of the national strategic nuclear policy is discussed and analyzed.

Analysis of the asbestos permissible-exposure-level threshold standard. Master's thesis  

SciTech Connect

This thesis examines the reasoning of the Occupational Safety and Health Administration's (OSHA) decision to set stringent exposure levels for airborne asbestos in the work place. Technical recommendations from the National Institute for Occupational Safety and Health (NIOSH), the Bureau of Mines, and the American conference of Governmental Industrial Hygienists were presented to OSHA for consideration. OSHA and the Environmental Protection Agency (EPA) set industry standards for permissible exposure levels (PEL) of airborne asbestos. Exposure to asbestos poses a health hazard to workers, their families, and consumers of asbestos products. Because it poses an unreasonable risk human life, OSHA has repeatedly lowered the Permissible Exposure Levels and the EPA will ban the manufacture, importation, processing and commercial distribution of asbestos containing products from the United States in phases by 1997. These decisions may have been made too hastily because of the long latency (15-40 years) period before cancer develops, and the added risks that smoking imposes.

ESKAPE/CF: A knowledge-acquisition tool for expert systems using cognitive feedback. Master's thesis  

SciTech Connect

The major bottleneck in the construction of expert systems is the time-consuming process of acquiring knowledge from experts. Automated knowledge acquisition tools have demonstrated the ability to reduce the time required to construct expert system knowledge bases and are supported by both knowledge engineers and experts. However, due to limitations in their underlying psychological paradigms, existing tools may not be well-suited to extracting semantic or procedural knowledge from an expert. This thesis designs and implements an Expert System Knowledge Acquisition and Policy Evaluation tool using Cognitive Feedback (ESKAPE/CF), based on Lens model techniques which have demonstrated effectiveness in capturing policy knowledge. The system is designed to be used interactively by an expert to reduce the historically lengthy interactions with a knowledge engineer. Additionally, the use of cognitive feedback techniques should enable the system to capture expertise that has heretofore been unobtainable by existing knowledge acquisition tools.

LCS Content Document Application  

NASA Technical Reports Server (NTRS)

My project at KSC during my spring 2011 internship was to develop a Ruby on Rails application to manage Content Documents..A Content Document is a collection of documents and information that describes what software is installed on a Launch Control System Computer. It's important for us to make sure the tools we use everyday are secure, up-to-date, and properly licensed. Previously, keeping track of the information was done by Excel and Word files between different personnel. The goal of the new application is to be able to manage and access the Content Documents through a single database backed web application. Our LCS team will benefit greatly with this app. Admin's will be able to login securely to keep track and update the software installed on each computer in a timely manner. We also included exportability such as attaching additional documents that can be downloaded from the web application. The finished application will ease the process of managing Content Documents while streamlining the procedure. Ruby on Rails is a very powerful programming language and I am grateful to have the opportunity to build this application.

Content Documents Management  

NASA Technical Reports Server (NTRS)

The Content Documents are created and managed under the System Software group with. Launch Control System (LCS) project. The System Software product group is lead by NASA Engineering Control and Data Systems branch (NEC3) at Kennedy Space Center. The team is working on creating Operating System Images (OSI) for different platforms (i.e. AIX, Linux, Solaris and Windows). Before the OSI can be created, the team must create a Content Document which provides the information of a workstation or server, with the list of all the software that is to be installed on it and also the set where the hardware belongs. This can be for example in the LDS, the ADS or the FR-l. The objective of this project is to create a User Interface Web application that can manage the information of the Content Documents, with all the correct validations and filters for administrator purposes. For this project we used one of the most excellent tools in agile development applications called Ruby on Rails. This tool helps pragmatic programmers develop Web applications with Rails framework and Ruby programming language. It is very amazing to see how a student can learn about OOP features with the Ruby language, manage the user interface with HTML and CSS, create associations and queries with gems, manage databases and run a server with MYSQL, run shell commands with command prompt and create Web frameworks with Rails. All of this in a real world project and in just fifteen weeks!

The observation of plasmaspheric electron content by FORMOSAT-3/COSMIC  

NASA Astrophysics Data System (ADS)

Previous studies examine changes of the electron density in the bottomside ionosphere, and however the total electron content (TEC) of the topside ionosphere and/or the plasmasphere has not been investigated in detail. This thesis derives the TEC from 800km to 20200km, termed the plasmaspheric electron content (PEC), by excess time delay of GPS signals recorded by the POD antenna onboard FORMOSAT-3/COSMIC (F3/C). The diurnal and seasonal variations of the PEC in 2009 and 2010 are investigated. Results show that PEC decrease polarward from magnetic equator and yield symmetry futures the southern and northern hemisphere in each season. In longitude, there are some PEC peaks alone the magnetic equator which reveal an obvious the seasonal difference between the Atlantic and South America area.t;

Thallium toxicity: The problem; an analytical approach; an antidotal study. Master's thesis  

SciTech Connect

Thallium (Tl) is a highly toxic metal that is anthropogenically concentrated in the environment. Tl toxicity and the quantitative analysis of trace levels of Tl in biologic materials by atomic absorption spectroscopy is reviewed; a study designed to evaluate the antidotal efficacy of 2 compounds in the treatment of acute Tl toxicity in rats is documented. Unithiol (2,3-dimercapto-1-propanesulfonic acid, DMPS) and prussian blue (potassium ferric hexacyanoferrate(II), PB), given alone and in combination, were evaluated as antidotes in the treatment of acute thallotoxicosis in male Sprauge-Dawley rats. The relative accumulation of Tl in organs was kidney>>heart>liver-brain. PB induced significant decorporation of Tl from all tissues. DMPS failed to significantly decrease the Tl content in any organ, but significantly decreased the Tl content in whole blood. PB+DMPS treatment significantly decreased the Tl content in all organs, but to no greater extent than PB alone. PB and PB+DMPS treatments significantly increased the Tl content of feces, whereas DMPS treatment alone produced little effect. This study indicates that PB is a beneficial antidote in the treatment of acute thallotoxicosis in rats. The failure of DMPS to significantly decrease the Tl content in 4 target organs suggests it would not be useful in the treatment of Tl poisoning....Thallium, Poison, Antidote, Chelator, Prussian blue, Potassium ferric hexacyanoferrate(II), Unithiol, 2,3-dimercapto-1-propanesulfonic acid, Rat.

Inorganic contents of peats  

SciTech Connect

Peat, the precursor of coal, is composed primarily of plant components and secondarily of inorganic matter derived from a variety of sources. The elemental, mineralogic, and petrographic composition of a peat is controlled by a combination of both its botanical and depositional environment. Inorganic contents of peats can vary greatly between geographically separated peat bogs as well as vertially and horizontally within an individual bog. Predicting the form and distribution of inorganic matter in a coal deposit requires understanding the distribution and preservation of inorganic matter in peat-forming environments and diagenetic alterations affecting such material during late-stage peatification and coalification processes. 43 refs., 4 figs., 3 tabs.

Electron content over Tucuman  

NASA Astrophysics Data System (ADS)

The Faraday electron (NF) content over Tucuman, Argentina, was determined from ATS 3 and GOES 3 measurements conducted between April 1982 and March 1983 near the maximum of the second highest solar cycle. The NF over Tucuman was found to be characterized by a day-to-day temporal variability, semiannual variation, equatorial anomaly influence, different behaviors during magnetic storms, and occasional postsunset second maximum. In comparison to other stations, including Hamilton (Massachusetts, U.S.), Haifa (Israel), and Ascension Island, it was found that the maximum value of NF has a similar order of magnitude, but occurs later than at other stations. The winter anomaly was observed only at Northern Hemisphere stations.

Random vibration analysis of the Topaz-II nuclear reactor power system. Master`s thesis  

SciTech Connect

The TOPAZ-II Ya-21U is one of six Russian made space nuclear power systems which is based on theomionic power conversion. The U.S. is presently analyzing TOPAZ-II to determine the reliability and feasibility of using this system. A structural analysis test was conducted on the TOPAZ unit in May 1993 to provide data from which modal parameters could be identified. This test showed the fundamental frequency to be 10.5 Hz, yet the test results that the Russians conducted identified a fundamental frequency of 5 Hz. Another finite element model was created incorporating new developments in TOPAZ-II and modifications to the finite element model to better simulate the mass properties of the TOPAZ-II2. A second structural analysis test was conducted on the TOPAZ unit 06-09 September 1994. This thesis focuses on the random vibration analysis of the TOPAZ-II Ya-2lU utilizing the most recent test results and the Master Series (updated version) I-DEAS software. The modal respose of the model and simulated random vibration tests were within 8.33%. This model is a feasible tool which can be used to analyze the TOPAZ unit without testing the unit to fatigue.

The Radical Plasticity Thesis: How the Brain Learns to be Conscious  

PubMed Central

In this paper, I explore the idea that consciousness is something that the brain learns to do rather than an intrinsic property of certain neural states and not others. Starting from the idea that neural activity is inherently unconscious, the question thus becomes: How does the brain learn to be conscious? I suggest that consciousness arises as a result of the brain's continuous attempts at predicting not only the consequences of its actions on the world and on other agents, but also the consequences of activity in one cerebral region on activity in other regions. By this account, the brain continuously and unconsciously learns to redescribe its own activity to itself, so developing systems of meta-representations that characterize and qualify the target first-order representations. Such learned redescriptions, enriched by the emotional value associated with them, form the basis of conscious experience. Learning and plasticity are thus central to consciousness, to the extent that experiences only occur in experiencers that have learned to know they possess certain first-order states and that have learned to care more about certain states than about others. This is what I call the “Radical Plasticity Thesis.” In a sense thus, this is the enactive perspective, but turned both inwards and (further) outwards. Consciousness involves “signal detection on the mind”; the conscious mind is the brain's (non-conceptual, implicit) theory about itself. I illustrate these ideas through neural network models that simulate the relationships between performance and awareness in different tasks.

Soviet Nordic nuclear-weapon free-zone proposal. Master's thesis  

SciTech Connect

This thesis examines the Soviet proposal and its ramifications for the United States and the West. The central theme running through each Soviet proposal has been removal of American nuclear guarantees. Preservation of US national security interests and hence US ability to extend its forward defense would be gravely threatened by such a NWFZ. However, unilateral agreement on a NWFZ is unlikely by the anticipated members of the Nordic NWFZ the US, USSR, Denmark, Norway, Finland, Iceland, Greenland, and Sweden. The US has military installations in Iceland and Greenland and banning of nuclear weapons during wartime is inconceivable. The question then arises as to which nation or groups of nations will dominate and which will acquiesce. Inevitably the debate breaks down to a tug of war between the two superpowers. It is really the politics surrounding the nuclear weapons that is the heart of the nuclear-free-zone debate. Changing world politics demand that the West develop a unified strategy toward the USSR. Through NATO it must preserve its vital economic political and military objectives in the Northern Flank. Flexible naval forces and strong political and economic ties to the governments of the nations bordering the Baltic are essential. Strong NATO naval forces operating in the Baltic Sea must be seen as guarantors of the West's strategic aims and interests. A Nordic NWFZ would prevent this.

Robust control design with real parameter uncertainty using absolute stability theory. Ph.D. Thesis  

NASA Technical Reports Server (NTRS)

The purpose of this thesis is to investigate an extension of mu theory for robust control design by considering systems with linear and nonlinear real parameter uncertainties. In the process, explicit connections are made between mixed mu and absolute stability theory. In particular, it is shown that the upper bounds for mixed mu are a generalization of results from absolute stability theory. Both state space and frequency domain criteria are developed for several nonlinearities and stability multipliers using the wealth of literature on absolute stability theory and the concepts of supply rates and storage functions. The state space conditions are expressed in terms of Riccati equations and parameter-dependent Lyapunov functions. For controller synthesis, these stability conditions are used to form an overbound of the H2 performance objective. A geometric interpretation of the equivalent frequency domain criteria in terms of off-axis circles clarifies the important role of the multiplier and shows that both the magnitude and phase of the uncertainty are considered. A numerical algorithm is developed to design robust controllers that minimize the bound on an H2 cost functional and satisfy an analysis test based on the Popov stability multiplier. The controller and multiplier coefficients are optimized simultaneously, which avoids the iteration and curve-fitting procedures required by the D-K procedure of mu synthesis. Several benchmark problems and experiments on the Middeck Active Control Experiment at M.I.T. demonstrate that these controllers achieve good robust performance and guaranteed stability bounds.

Conic Sector Analysis of Hybrid Control Systems. Ph.D. Thesis  

NASA Technical Reports Server (NTRS)

A hybrid control system contains an analog plant and a hybrid (or sampled-data) compensator. In this thesis a new conic sector is determined which is constructive and can be used to: (1) determine closed loop stability, (2) analyze robustness with respect to modelling uncertainties, (3) analyze steady state response to commands, and (4) select the sample rate. The use of conic sectors allows the designer to treat hybrid control systems as though they were analog control systems. The center of the conic sector can be used as a rigorous linear time invariant approximation of the hybrid control system, and the radius places a bound on the errors of this approximation. The hybrid feedback system can be multivariable, and the sampler is assumed to be synchronous. Algorithms to compute the conic sector are presented. Several examples demonstrate how the conic sector analysis techniques are applied. Extensions to single loop multirate hybrid feedback systems are presented. Further extensions are proposed for multiloop multirate hybrid feedback system and for single rate systems with asynchronous sampling.

Failure analysis and modeling of a multicomputer system. M.S. Thesis  

NASA Technical Reports Server (NTRS)

This thesis describes the results of an extensive measurement-based analysis of real error data collected from a 7-machine DEC VaxCluster multicomputer system. In addition to evaluating basic system error and failure characteristics, we develop reward models to analyze the impact of failures and errors on the system. The results show that, although 98 percent of errors in the shared resources recover, they result in 48 percent of all system failures. The analysis of rewards shows that the expected reward rate for the VaxCluster decreases to 0.5 in 100 days for a 3 out of 7 model, which is well over a 100 times that for a 7-out-of-7 model. A comparison of the reward rates for a range of k-out-of-n models indicates that the maximum increase in reward rate (0.25) occurs in going from the 6-out-of-7 model to the 5-out-of-7 model. The analysis also shows that software errors have the lowest reward (0.2 vs. 0.91 for network errors). The large loss in reward rate for software errors is due to the fact that a large proportion (94 percent) of software errors lead to failure. In comparison, the high reward rate for network errors is due to fast recovery from a majority of these errors (median recovery duration is 0 seconds).

Oil policy in Russia toward selected new independent states. Master thesis  

SciTech Connect

Following the breakdown of the Soviet Union, one of the world`s strongest oil producing industries was divided into a few major oil provinces. The process of change to the former Soviet oil industry including: Russian efforts to maintain control of its former resources, NIS resource development, Western capital investment, and environmental issues in the major oil provinces of the former Soviet Union, is the main focus of this thesis. Free market world oil majors and their counterparts, both in Russia and the New Independent States (NIS), have developed a number of significant alliances that have resulted in several potentially lucrative joint ventures. The coercive tactics that the Russian government resorts to in an effort to prevent its former republics from efficiently developing their reserves, and the position the United States must take to ensure these efforts are stifled will be addressed. A sound grasp of these critical energy issues by American policy makers will result in the development of these vast resources in a manner favorable to U. S. national interests.

Strategic culture and ballistic missile defense: Russia and the United States. Master's thesis  

SciTech Connect

This thesis examines U.S. and Russian history and current policy debates to advance understanding of: (1) the strategic cultures of these nations, particularly with respect to BMD policies in the recent past; and (2) whether and how their strategic cultures and approaches to BMD are changing and how that may affect future strategic BMD developments and the status of the ABM Treaty. The development of BMD strategies, including policies concerning the ABM Treaty, within the framework of the established American and Russian strategic cultures is studied, with due attention to the Soviet experience and legacy in the Russian case. U.S. strategic culture does not seem to have changed significantly with the end of the Cold War, but U.S. BMD priorities have been redefined to reflect a higher priority attached to regional and theater-level defenses. It is apparent that the Soviet experience did have a significant impact on Russian strategic culture. Faced with major changes in its international status, domestic political-military arrangements, and scope of national security concerns, Russian strategic culture is nonetheless moving beyond the old Soviet culture. Future Russian policies regarding the transfer of BMD technology, sharing early warning data, and participating in a global protective system are heavily dependent on domestic political developments.

Magnetic field measurements of the CEBAF (NIST) wiggler using the pulsed wire method. Master's thesis  

SciTech Connect

The Free Electron Laser (FEL) has proven to be a versatile photon source for many applications in science, industry and defense. It is capable of providing wide tunability and high efficiency, but has yet to yield high average power required as a weapon system. The proposed infrared and ultraviolet FELs at the Continuous Electron Beam Accelerator Facility (CEBAF) have been projected to provide high average power. The first section of this thesis will study the necessity of a FEL for shipboard defense, and state the advantages over other defense systems. The remainder will focus on use of the pulsed wire method for measuring the magnetic field errors of the CEBAF/National Institute of Science and Technology (NIST) wiggler. Data analysis indicates the wiggler will have a net electron beam deflection of x=5.2mm, which is much greater than the electron beam radius of re=0.4mm and the optical mode waist of wo=1mm...

The robotic system under development consists of a land vehicle, an aerial vehicle, and a ground-based control station. Reliable communication between these three stations is needed. A traditional wire-based network requires that the vehicles be tethered and severely limits the mobility of the vehicles. A wireless Local Area Network (LAN) is proposed to provide communications between the control station and the vehicles. The objective of this thesis is to develop the physical (hardware) and logical (software) architecture of a wireless LAN that accommodates the needs of the mine/UXO project. Through an analysis of wireless modulation techniques, a market survey of wireless devices, and a field testing of wireless devices, a wireless LAN is designed to meet the technological, performance, regulation, interference, and mobility requirements of the mine/UXO project. Finally, the wireless communication protocols and the development of an error-free application protocol (specified by a FSM model and implemented in ANSI C code using Windows socket network programming) completes the wireless LAN implementation.

Decision models for conducting an economic analysis of alternative fuels for the ice engine. Master's thesis  

SciTech Connect

An economic analysis is made of vehicles powered by compressed natural gas (CNG), alcohol, and electric vehicles (EV's) as possible replacements for gasoline-powered vehicles. Advantages and disadvantages of vehicles powered by the various fuels are discussed and determinations of their suitability are made based on vehicle performance characteristics and fuel availability. CNG and EV's are determined to be viable alternatives based on current state-of-the-art technology. Alcohol is not retained as a viable alternative because of limited fuel availability. Models are presented for determining the total life cycle cost for gasoline, CNG, and EV's. A fleet of seventy-two vehicles at the Naval Postgraduate School is used as an example to compare the cost of each alternative. A linear program is used to determine the mix of gasoline, CNG, and electric vehicles that satisfy mission requirements for the least total fleet life cycle cost and to perform sensitivity analysis on the cost determinants. A generalized formulation is also presented to allow a vehicle fleet manager to use the methodology of this thesis as an aid to evaluating the potential of alternatively-fueled vehicles in different situations.

A procedure for determining the resource utilization potential of coal ash. Master's thesis  

SciTech Connect

A combination of the increased utilization of coal as an energy source and more stringent environmental regulations is creating problems for the disposal of the ash by-product from the combustion of coal. Utilization of the coal ash as an alternate resource has proven to be a partial solution to the problem. The U.S. Air Force coal conversion program will increase coal consumption and the production of coal ash; this has a potential to create a disposal problem for coal-burning bases. The purpose of this thesis was to develop a procedure to aid an engineer in determining the resource utilization potential of the coal ash at the base. The quality and quantity of the ash are the two main factors that affect the resource utilization potential of the ash. These two factors are a function of the nature of the feed coal, and the production, collection, handling, and storage systems utilized at the base. The procedure does not address the determination of the market potential of the ash, but rather its potential to be utilized as an alternate resource. The procedure provides a sequence of steps to follow in determining the resource utilization potential of a coal ash.

Investigation of finite element: ABC methods for electromagnetic field simulation. Ph.D. Thesis  

NASA Technical Reports Server (NTRS)

The mechanics of wave propagation in the presence of obstacles is of great interest in many branches of engineering and applied mathematics like electromagnetics, fluid dynamics, geophysics, seismology, etc. Such problems can be broadly classified into two categories: the bounded domain or the closed problem and the unbounded domain or the open problem. Analytical techniques have been derived for the simpler problems; however, the need to model complicated geometrical features, complex material coatings and fillings, and to adapt the model to changing design parameters have inevitably tilted the balance in favor of numerical techniques. The modeling of closed problems presents difficulties primarily in proper meshing of the interior region. However, problems in unbounded domains pose a unique challenge to computation, since the exterior region is inappropriate for direct implementation of numerical techniques. A large number of solutions have been proposed but only a few have stood the test of time and experiment. The goal of this thesis is to develop an efficient and reliable partial differential equation technique to model large three dimensional scattering problems in electromagnetics.

Design guidelines for a rule-based passive surveillance system. Master's thesis  

SciTech Connect

This thesis addresses the application of artificial intelligence to passive surveillance systems that use waveform analysis as their primary means of detecting, classifying, and locating a specific target. Discussion is further limited to those passive surveillance systems which must deal with considerable noise in the data. Present methods, which use visual examination of the waveform data for the detection of target waveforms, is complicated, time consuming, and requires considerable expertise. The lack of prior knowledge of the nature of the noise, (e.g., frequency spectra, amplitude, or dynamics), means that the majority of signal analysis must be done by experts. This study discusses and recommends a rule-based system which uses the following artificial-intelligence structures: the blackboard architecture, and the frames data structure. Sources of uncertainty are also discussed and methods of dealing with it are suggested. This study recommends that the symbolic representation language be carefully selected for conciseness, efficiency, and a vocabulary rich enough to express everything desired by the experts. A learning knowledge source is also recommended.

Error modeling for differential GPS. M.S. Thesis - MIT, 12 May 1995  

NASA Technical Reports Server (NTRS)

Differential Global Positioning System (DGPS) positioning is used to accurately locate a GPS receiver based upon the well-known position of a reference site. In utilizing this technique, several error sources contribute to position inaccuracy. This thesis investigates the error in DGPS operation and attempts to develop a statistical model for the behavior of this error. The model for DGPS error is developed using GPS data collected by Draper Laboratory. The Marquardt method for nonlinear curve-fitting is used to find the parameters of a first order Markov process that models the average errors from the collected data. The results show that a first order Markov process can be used to model the DGPS error as a function of baseline distance and time delay. The model's time correlation constant is 3847.1 seconds (1.07 hours) for the mean square error. The distance correlation constant is 122.8 kilometers. The total process variance for the DGPS model is 3.73 sq meters.

Israeli nuclear weapons and war in the Middle East. Master`s thesis  

SciTech Connect

This thesis examines the influence of the Israeli nuclear weapons capability on conflict in the Middle East. There are two perspectives regarding the impact of nuclear proliferation on strategic stability. Three paths to strategic instability are examined: preventive attacks, preemptive attacks, and the escalation of conventional conflict to nuclear war. The optimistic perspective argues that nuclear weapons make preventive and preemptive attacks less likely, and keep conventional conflict from escalating to nuclear war. The pessimistic perspective argues the opposite that nuclear weapons make preventive and preemptive attacks more likely, and raise the likelihood of escalation to nuclear war. My analysis of the Israeli cases shows that opaque nuclear proliferation decreases the pressure for preventive attacks, increases the chances for miscalculation, and creates sufficient concern about nuclear weapons to reduce the likelihood of preemptive attacks. Two factors help reduce the risk of nuclear proliferation as posed by proliferation pessimists, opaque nuclear weapons programs and nondeclaratory nuclear weapons policies. The implication of this research is that if the United States cannot dissuade a country from going nuclear, it should reinforce its incentives to maintain opacity and a nondeclaratory policy. Particular attention should be given to states which resist these efforts, as they represent the greatest risk of nuclear weapons use.

Design for dependability: A simulation-based approach. Ph.D. Thesis, 1993  

NASA Technical Reports Server (NTRS)

This research addresses issues in simulation-based system level dependability analysis of fault-tolerant computer systems. The issues and difficulties of providing a general simulation-based approach for system level analysis are discussed and a methodology that address and tackle these issues is presented. The proposed methodology is designed to permit the study of a wide variety of architectures under various fault conditions. It permits detailed functional modeling of architectural features such as sparing policies, repair schemes, routing algorithms as well as other fault-tolerant mechanisms, and it allows the execution of actual application software. One key benefit of this approach is that the behavior of a system under faults does not have to be pre-defined as it is normally done. Instead, a system can be simulated in detail and injected with faults to determine its failure modes. The thesis describes how object-oriented design is used to incorporate this methodology into a general purpose design and fault injection package called DEPEND. A software model is presented that uses abstractions of application programs to study the behavior and effect of software on hardware faults in the early design stage when actual code is not available. Finally, an acceleration technique that combines hierarchical simulation, time acceleration algorithms and hybrid simulation to reduce simulation time is introduced.

Entrepreneurial proliferation: Russia`s nuclear industry suits the buyers market. Master`s thesis  

SciTech Connect

The Soviet Union collapsed in December 1991, bringing an end to four decades of the Cold War. A system of tight centralized controls has given way to chaotic freedom and un-managed, entrepreneurial capitalism. Of immediate concern to most world leaders has been the control and safety of over 30,000 Soviet nuclear weapons. After 1991, the Soviet, centralized system of management lost one key structural element: a reliable `human factor` for nuclear material control. The Soviet systems for physical security and material control are still in place in the nuclear inheritor states - Russia, Ukraine, Khazakhnstan, and Belarus - but they do not restrain or regulate their nuclear industry. In the chaos created by the Soviet collapse, the nonproliferation regime may not adequately temper the supply of the nuclear materials of the new inheritor states. This could permit organizations or states seeking nuclear weapons easier access to fissile materials. New initiatives such as the United States Cooperative Threat Reduction program, which draws upon U.S. technology and expertise to help the NIS solve these complex problems, are short-tern tactics. At present there are no strategies which address the long-tern root problems caused by the Soviet collapse.This thesis demonstrates the extent of the nuclear control problems in Russia. Specifically, we examine physical security, material control and accounting regulation and enforcement, and criminal actions. It reveals that the current lack of internal controls make access to nuclear materials easier for aspiring nuclear weapons States.

Resource sharing on CSMA/CD networks in the presence of noise. M.S. Thesis  

NASA Technical Reports Server (NTRS)

Resource sharing on carrier sense multiple access with collision detection (CSMA/CD) networks can be accomplished by using window-control algorithms for bus contention. The window-control algorithms are designed to grant permission to transmit to the station with the minimum contention parameter. Proper operation of the window-control algorithm requires that all stations sense the same state of the newtork in each contention slot. Noise causes the state of the network to appear as a collision. False collisions can cause the window-control algorithm to terminate without isolating any stations. A two-phase window-control protocol and approximate recurrence equation with noise as a parameter to improve the performance of the window-control algorithms in the presence of noise are developed. The results are compared through simulation, with the approximate recurrence equation yielding the best overall performance. Noise is even a bigger problem when it is not detected by all stations. In such cases it is possible for the window boundaries of the contending stations to become out of phase. Consequently, it is possible to isolate a station other than the one with the minimum contention parameter. To guarantee proper isolation of the minimum, a broadcast phase must be added after the termination of the algorithm. The protocol required to correct the window-control algorithm when noise is not detected by all stations is discussed.

Process improvement to the inspection readiness plan in chemical weapons convention challenge inspections. Master`s thesis  

SciTech Connect

This thesis identified current Information Technology initiatives to help improve the Navy`s Inspection Readiness Plan for Chemical Warfare Convention (CWC) Challenge Inspection. The CWC is an intensive inspection. The Challenge Inspection allows for a team of international inspectors to inspect a naval facility suspected of violating the CWC on very short notice. This thesis begins with a review of the CWC Challenge Inspection timeline. It then describes the Navy`s Inspection Readiness Plan for CWC Challenge Inspections as well as the Navy Tiger Team that is sent to naval facilities to assist the Commanding Officer and base personnel during inspections. One of the initiatives evaluated by this analysis is the use of videoconferencing. To ascertain the feasibility of using videoconferencing in the CWC Challenge Inspection process, this thesis reviews the current videoconferencing systems and standards, and the results of a questionnaire that was sent to various naval commands. This thesis concludes with recommendations for inclusion of videoconferencing and various other Information Technology initiatives in the CWC Challenge Inspection process.

US foreign policy and the Baltic states. Master`s thesis  

SciTech Connect

This thesis examines U. S. foreign policy toward the Baltic states from 1918 to 1991 to determine if the U.S. has been realistic in its dealings with small nations. An analysis of U.S. policy indicates that the United States acts hypocritically by accepting compromises on the very moral principals to which it claims to be the protectorate of when domestic political costs are high. The sacrifice of national values degrades the credibility of the moral high ground necessary for U.S. policy. This study reviews the events that occurred during the three major periods in U.S.-Baltic relations: The initial period of Baltic independence following World War I; the Soviet annexation of the Baltics during World War II: and finally the beginning of the second period of Baltic independence during the breakup of the Soviet Union. In all three cases U.S. policy was unclear and contradictory. The Baltic case provides a good example of the tendency for U.S. policy to be paradoxical and ineffective. This study concludes that despite the U.S. policy of nonrecognition of the Soviet annexation of the Baltic states during the Cold War, the United States failed to adhere to its principals when given the opportunity. In the process, it also neglected problems within its borders that required attention perhaps more urgently than those outside. The tendency for U.S. policy to ignore the issues that actually threaten its security internally and placing a higher priority on external matters that do not have a real impact on its standing could likely lead to its inadvertent downfall.

Efficient modeling of interconnects and capacitive discontinuities in high-speed digital circuits. Thesis  

NASA Technical Reports Server (NTRS)

Modeling of interconnects and associated discontinuities with the recent advances high-speed digital circuits has gained a considerable interest over the last decade although the theoretical bases for analyzing these structures were well-established as early as the 1960s. Ongoing research at the present time is focused on devising methods which can be applied to more general geometries than the ones considered in earlier days and, at the same time, improving the computational efficiency and accuracy of these methods. In this thesis, numerically efficient methods to compute the transmission line parameters of a multiconductor system and the equivalent capacitances of various strip discontinuities are presented based on the quasi-static approximation. The presented techniques are applicable to conductors embedded in an arbitrary number of dielectric layers with two possible locations of ground planes at the top and bottom of the dielectric layers. The cross-sections of conductors can be arbitrary as long as they can be described with polygons. An integral equation approach in conjunction with the collocation method is used in the presented methods. A closed-form Green's function is derived based on weighted real images thus avoiding nested infinite summations in the exact Green's function; therefore, this closed-form Green's function is numerically more efficient than the exact Green's function. All elements associated with the moment matrix are computed using the closed-form formulas. Various numerical examples are considered to verify the presented methods, and a comparison of the computed results with other published results showed good agreement.

Method for optimizing resource allocation in a government organization. Ph.D. Thesis  

NASA Technical Reports Server (NTRS)

The managers in Federal agencies are challenged to control the extensive activities in government and still provide high-quality products and services to the American taxpayers. Considering today's complex social and economic environment and the $3.8 billion daily cost of operating the Federal Government, it is evident that there is a need to develop decision-making tools for accurate resource allocation and total quality management. The goal of this thesis is to provide a methodical process that will aid managers in Federal Government to make budgetary decisions based on the cost of services, the agency's objectives, and the customers' perception of the agency's product. A general resource allocation procedure was developed in this study that can be applied to any government organization. A government organization, hereafter the 'organization,' is assumed to be a multidivision enterprise. This procedure was applied to a small organization for the proof of the concept. This organization is the Technical Services Directorate (TSD) at the NASA Lewis Research Center in Cleveland, Ohio. As part of the procedure, a nonlinear programming model was developed to account for the resources of the organization, the outputs produced by the organization, the decision-maker's views, and the customers' satisfaction with the organization. The information on the resources of the organization was acquired from current budget levels of the organization and the human resources assigned to the divisions. The outputs of the organization were defined and measured by identifying metrics that assess the outputs, the most challenging task in this study. The decision-maker's views are represented in the model as weights assigned to the various outputs and were quantified by using the analytic hierarchy process. The customer's opinions regarding the outputs of the organization were collected through questionnaires that were designed for each division individually. Following the philosophy of total quality management, information on customers' satisfaction is presented in the model as the quality of output. The model is a nonlinear one whose objective is to maximize customers' satisfaction such that the total cost of operation does not exceed the organization's budget. This model represents a structured approach or policy mechanism, at the agency level, to make capital investment decisions based on the priorities of the agency and the quality of outputs. This procedure applied to TSD resulted in a resources allocation scheme that was reasonable and acceptable to the decision-makers and, as expected, dependent on the assumptions and accuracy of the data used in the model.

Solubilization and spore recovery from silicone polymers. Ph.D. Thesis  

NASA Technical Reports Server (NTRS)

A non-sporicidal technique for solvent degradation of cured silicone polymers was developed which involves chemical degradation of cured silicone polymers by amine solvents at room temperature. Substantial improvements were obtained in the recovery of seeded spores from room temperature cured polymers as compared to the standard recovery procedures, which indicates that the curing process is not sufficiently exothermic to reduce spore viability. The dissolution reaction of cured silicone polymers whith amine solvents is proposed to occur by bimolecular nucleophilic displacement. The chemical structure of silicone polymers was determined by spectroscopic methods. The phenyl to methyl ratio, R/Si ratio, molecular weight, and hydroxyl content of the silicone resins were determined.

Overlay coating degradation by simultaneous oxidation and coating/substrate interdiffusion. Ph.D. Thesis  

NASA Technical Reports Server (NTRS)

Degradation of NiCrAlZr overlay coatings on various NiCrAl substrates was examined after cyclic oxidation. Concentration/distance profiles were measured in the coating and substrate after various oxidation exposures at 1150 C. For each stubstrate, the Al content in the coating decreased rapidly. The concentration/distance profiles, and particularly that for Al, reflected the oxide spalling resistance of each coated substrate. A numerical model was developed to simulate diffusion associated with overlay-coating degradation by oxidation and coating/substrate interdiffusion. Input to the numerical model consisted of the Cr and Al content of the coating and substrate, ternary diffusivities, and various oxide spalling parameters. The model predicts the Cr and Al concentrations in the coating and substrate after any number of oxidation/thermal cycles. The numerical model also predicts coating failure based on the ability of the coating to supply sufficient Al to the oxide scale. The validity of the model was confirmed by comparison of the predicted and measured concentration/distance profiles. The model was subsequently used to identify the most critical system parameters affecting coating life.

Thermal-shock resistance of mullite-based SiC-whisker composites. Master's thesis  

SciTech Connect

The influence of the addition of silicon carbide (SiC) whiskers and zirconia on the material properties and constants of pure mullite was examined. SiC whisker weight percentages of 0, 10, 20, and 30 were examined, and a zirconia content of 36.1 wt.% was studied. A theoretical approach similar to Hasselman's high-E, low-E theory was used to determine the theoretical values of the material properties, which were then compared to experimental results. Using experimental and theoretical values for Young's modulus of elasticity, bend strength, mean coefficient of thermal expansion, thermal diffusivity, and Poisson's ratio, the thermal-stress-resistance parameters were calculated, and compared to experimental results for critical quench temperatures. Microstructures were characterized by x-ray diffraction (XRD) analysis, chemical analysis, density determinations, light microscopy (LM), and scanning electron microscopy (SEM). The mullite was alumina-rich with particles of silica present. Whisker composites contained 2H, 4H, and 15R polytypes of SiC and impurities from the whisker. Mullite-zirconia microstructures contained partially-stabilized zirconia with monoclinic:tetragonal ratios of 90%. Increasing SiC whisker content decreased the Poisson's ratio and mean coefficient of thermal expansion of the specimen and increased the elastic modulus, bend strength, and thermal diffusivity of the composites.

Analysis of the morality of intention in nuclear deterrence, with special reference to final retaliation. Doctoral thesis  

SciTech Connect

Quite apart from its apparent political obsolescence, the policy of nuclear deterrence is vulnerable to attack for its seemingly obvious immorality. Nuclear war is blatantly immoral, and nuclear deterrence requires a genuine intention to resort to the nuclear retaliation which would precipitate such a war. Therefore, since it is wrong to intend that which is wrong to do, deterrence is immoral. This thesis seeks to examine the nature of the deterrent intention as a means of verifying the soundness of the above deontological argument. This examination is carried out by first suggesting an acceptable notion of intention in general and then, after analysing the views of deterrent intention by other writers, proceeding to demonstrate the uniqueness of that intention. Having done this, and having explored the possibility that deterrence need not contain a genuine intention to retaliate, the thesis moves on to suggest and defend a moral principle which states that endeavours requiring the formation of an immoral intention may nevertheless be moral. Called the Principle of Double Intention (and based on the Principle of Double Effect), it offers a method for the moral assessment of agents who form immoral intentions within larger contexts. By applying this principle to nuclear deterrence, it is demonstrated that agents who undertake such a policy may be morally justified in doing so, provided certain conditions are met. The thesis closes with a refutation of the objection that an agent cannot rationally form an intention (such as that required in deterrence) which he has no reason to carry out.

[Beyond Weimar Culture--the significance of the Forman thesis for a cultural approach to the history of science].  

PubMed

'"Forman thesis', published in 1971, argued for a historical linkage among the intellectual atmosphere of Weimar Germany, popular revolts against determinism and materialism, and the creation of the revolutionary new theory of quantum mechanics. Paul Forman's long essay on "Weimar Culture" has shaped research agendas in numerous fields, from the history and philosophy of physics to German history to the sociology of scientific knowledge. Despite its status as a classic and its transformative effect, Weimar Culture has always inspired as much critique as assent. In particular in the history of science, cohorts of students and two generations of scholars have debated the Forman thesis as a conceptual tool for linking scientific change with cultural processes. The Forman thesis raises critical questions for both the ongoing debates over cultural approaches to the history of science and the burgeoning newer scholarship on physics in and beyond Weimar Germany. Exploring these implications has been the aim of a transnational project of the three authors of this article which sheds some light on these debates and briefly introduces the following papers of this special issue devoted to Paul Forman and his seminal works in the history of science.

Evolution and Development of Dual Ingestion Systems in Mammals: Notes on a New Thesis and Its Clinical Implications  

PubMed Central

Traditionally, the development of oral feeding is viewed as a continuous, unitary process in which reflex-dominated sucking behavior gives rise to a more varied and volitional feeding behavior. In contrast, we consider the thesis that the infant develops two separable ingestive systems, one for suckling and one for feeding. First, we apply an evolutionary perspective, recognizing that suckling-feeding is a universal, mammalian developmental sequence. We find that in mammalian evolution, feeding systems in offspring were established prior to the evolution of lactation, and therefore suckling is a separable feature that was added to feeding. We next review an experimental literature that characterizes suckling and feeding as separable in terms of their topography, sensory controls, physiological controls, neural substrates, and experience-based development. Together, these considerations constitute a view of “dual ingestive systems.” The thesis, then, is that suckling is not a simple precursor of feeding but is a complete behavior that emerges, forms, and then undergoes a dissolution that overlaps with the emergence of independent feeding. This thesis guides us to focus differently on the challenges of properly managing and facilitating oral ingestion in infants, especially those born preterm, prior to the developmental onset of suckling.

KARL: A Knowledge-Assisted Retrieval Language. M.S. Thesis Final Report, 1 Jul. 1985 - 31 Dec. 1987  

NASA Technical Reports Server (NTRS)

Data classification and storage are tasks typically performed by application specialists. In contrast, information users are primarily non-computer specialists who use information in their decision-making and other activities. Interaction efficiency between such users and the computer is often reduced by machine requirements and resulting user reluctance to use the system. This thesis examines the problems associated with information retrieval for non-computer specialist users, and proposes a method for communicating in restricted English that uses knowledge of the entities involved, relationships between entities, and basic English language syntax and semantics to translate the user requests into formal queries. The proposed method includes an intelligent dictionary, syntax and semantic verifiers, and a formal query generator. In addition, the proposed system has a learning capability that can improve portability and performance. With the increasing demand for efficient human-machine communication, the significance of this thesis becomes apparent. As human resources become more valuable, software systems that will assist in improving the human-machine interface will be needed and research addressing new solutions will be of utmost importance. This thesis presents an initial design and implementation as a foundation for further research and development into the emerging field of natural language database query systems.

Localized content based image retrieval  

Microsoft Academic Search

Classic Content-Based Image Retrieval (CBIR) takes a single non-annotated query image, and retrieves similar images from an image repository. Such a search must rely upon a holistic (or global) view of the image. Yet often the desired content of an image is not holistic, but is localized. Specifically, we define Localized Content-Based Image Retrieval as a CBIR task where the

On the joint spectral density of bivariate random sequences. Thesis Technical Report No. 21  

NASA Technical Reports Server (NTRS)

For univariate random sequences, the power spectral density acts like a probability density function of the frequencies present in the sequence. This dissertation extends that concept to bivariate random sequences. For this purpose, a function called the joint spectral density is defined that represents a joint probability weighing of the frequency content of pairs of random sequences. Given a pair of random sequences, the joint spectral density is not uniquely determined in the absence of any constraints. Two approaches to constraining the sequences are suggested: (1) assume the sequences are the margins of some stationary random field, (2) assume the sequences conform to a particular model that is linked to the joint spectral density. For both approaches, the properties of the resulting sequences are investigated in some detail, and simulation is used to corroborate theoretical results. It is concluded that under either of these two constraints, the joint spectral density can be computed from the non-stationary cross-correlation.

A content propagation metric for efficient content distribution  

Microsoft Academic Search

Efficient content distribution in large networks comprising datacenters, end hosts, and distributed in-network caches is a difficult problem. Existing systems rely on mechanisms and metrics that fail to effectively utilize all available sources of bandwidth in the network. This paper presents a novel metric, called the Content Propagation Metric (CPM), for quantitatively evaluating the marginal benefit of available bandwidth to

A real-time diagnostic and performance monitor for UNIX. M.S. Thesis  

NASA Technical Reports Server (NTRS)

There are now over one million UNIX sites and the pace at which new installations are added is steadily increasing. Along with this increase, comes a need to develop simple efficient, effective and adaptable ways of simultaneously collecting real-time diagnostic and performance data. This need exists because distributed systems can give rise to complex failure situations that are often un-identifiable with single-machine diagnostic software. The simultaneous collection of error and performance data is also important for research in failure prediction and error/performance studies. This paper introduces a portable method to concurrently collect real-time diagnostic and performance data on a distributed UNIX system. The combined diagnostic/performance data collection is implemented on a distributed multi-computer system using SUN4's as servers. The approach uses existing UNIX system facilities to gather system dependability information such as error and crash reports. In addition, performance data such as CPU utilization, disk usage, I/O transfer rate and network contention is also collected. In the future, the collected data will be used to identify dependability bottlenecks and to analyze the impact of failures on system performance.

Ductility and fracture in B2 FeAl alloys. Ph.D. Thesis Final Report  

NASA Technical Reports Server (NTRS)

The mechanical behavior of B2FeAl alloys was studied. Stoichiometric Fe-50Al exhibits totally brittle behavior while iron-rich Fe-40Al yields and displays about 3% total strain. This change in behavior results from large decreases in the yield strength with iron-rich deviations from stoichiometry while the fracture stress remains essentially constant. Single crystal studies show that these yield strength decreases are directly related to decreases in the critical resolved shear stress for a group of zone axes /111/ set of (110) planes slip. This behavior is rationalized in terms of the decrease in antiphase boundary energy with decreasing aluminum content. The addition of boron results in improvements in the mechanical behavior of alloys on the iron-rich side of stoichiometry. These improvements are increased brittle fracture stresses of near-stoichiometric alloys, and enhanced ductility of up to 6% in Fe-40Al. These effects were attributed to increased grain boundary adhesion as reflected by changes in fracture mode from intergranular to transgranular failure. The increases in yield strength, which are observed in both polycrystals and single crystals, result from the quenching in of large numbers of thermal vacancies. Hall-Petch plots show that the cooling rate effects are a direct result of changes in the Hall-Petch intercept/lattice resistance flow.

Pulmonary Edema and Plasma Volume Changes in Dysbarism. M.S. Thesis - Texas Univ.  

NASA Technical Reports Server (NTRS)

Two groups of anesthetized, fasted pigs were utilized. One group of 13 animals (8.5 to 16.6 kilograms) was exposed to a high-pressure environment, and the other group of eight animals (6.9 to 20.0 kilograms) constituted the control group. The experimental group was subjected to an atmosphere of 90 percent nitrogen and 10 percent oxygen at a pressure of 50 psig for 30 minutes and then decompressed at a rate 10 psi/min. Plasma volumes, using both iodine-125-tagged-albumin and chromium-51-tagged-cell dilution techniques, were measured before, immediately after, and at 30 and 60 minutes after decompression. Aortic and right-ventricular systolic pressures were also recorded. At 60 minutes after decompression, blood samples were taken, the animals were sacrificed, and the water content of the lungs, kidneys, livers, and spleens was estimated by measuring tissue wet weight and dry weight. Protein extravasation and tissue blood volumes were determined by measuring the iodine-125-tagged-albumin and chromium-51-tagged-cell spaces in homo-genates of the organs under investigation.

Progressive transmission of pseudo-color images. Appendix 1: Item 4. M.S. Thesis  

NASA Technical Reports Server (NTRS)

The transmission of digital images can require considerable channel bandwidth. The cost of obtaining such a channel can be prohibitive, or the channel might simply not be available. In this case, progressive transmission (PT) can be useful. PT presents the user with a coarse initial image approximation, and then proceeds to refine it. In this way, the user tends to receive information about the content of the image sooner than if a sequential transmission method is used. PT finds application in image data base browsing, teleconferencing, medical and other applications. A PT scheme is developed for use with a particular type of image data, the pseudo-color or color mapped image. Such images consist of a table of colors called a colormap, plus a 2-D array of index values which indicate which colormap entry is to be used to display a given pixel. This type of image presents some unique problems for a PT coder, and techniques for overcoming these problems are developed. A computer simulation of the color mapped PT scheme is developed to evaluate its performance. Results of simulation using several test images are presented.

Visual Analysis of Weblog Content  

SciTech Connect

In recent years, one of the advances of the World Wide Web is social media and one of the fastest growing aspects of social media is the blogosphere. Blogs make content creation easy and are highly accessible through web pages and syndication. With their growing influence, a need has arisen to be able to monitor the opinions and insight revealed within their content. In this paper we describe a technical approach for analyzing the content of blog data using a visual analytic tool, IN-SPIRE, developed by Pacific Northwest National Laboratory. We highlight the capabilities of this tool that are particularly useful for information gathering from blog data.

[Exploring dream contents by neuroimaging].  

PubMed

Dreaming is a subjective experience during sleep that is often accompanied by vivid perceptual and emotional contents. Because of its fundamentally subjective nature, the objective study of dream contents has been challenging. However, since the discovery of rapid eye movements during sleep, scientific knowledge on the relationship between dreaming and physiological measures including brain activity has accumulated. Recent advances in neuroimaging analysis methods have made it possible to uncover direct links between specific dream contents and brain activity patterns. In this review, we first give a historical overview on dream researches with a focus on the neurophysiological and behavioral signatures of dreaming. We then discuss our recent study in which visual dream contents were predicted, or decoded, from brain activity during sleep onset periods using machine learning-based pattern recognition of functional MRI data. We suggest that advanced analytical tools combined with neural and behavioral databases will reveal the relevance of spontaneous brain activity during sleep to waking experiences. PMID:24748094

High recall document content extraction  

NASA Astrophysics Data System (ADS)

We report methodologies for computing high-recall masks for document image content extraction, that is, the location and segmentation of regions containing handwriting, machine-printed text, photographs, blank space, etc. The resulting segmentation is pixel-accurate, which accommodates arbitrary zone shapes (not merely rectangles). We describe experiments showing that iterated classifiers can increase recall of all content types, with little loss of precision. We also introduce two methodological enhancements: (1) a multi-stage voting rule; and (2) a scoring policy that views blank pixels as a "don't care" class with other content classes. These enhancements improve both recall and precision, achieving at least 89% recall and at least 87% precision among three content types: machine-print, handwriting, and photo.

Strategic plan for the Persian Gulf region: Options for deterring and/or defeating an emerging threat. Master's thesis  

SciTech Connect

The Persian Gulf region is, in all likelihood, going to remain crucial to American interests through the next several decades. The world depends on the petroleum reserves of the Gulf region to fuel its economic engine. The recent history of the region has been rife with conflict, and the U.S. has had to intervene militarily on several occasions to ensure its vital interests were protected. This thesis examines the strategic circumstances in the Gulf region and ways in which American political, diplomatic, and military policy can help shape the environment to conform to its interests. Several scenarios are developed which attempt to forecast the results of different environments on regional stability. The thesis reaches the conclusion that the United States must take a proactive role if its short- and long-term interests are to be protected. The short-term goal of U.S. policy must be to maintain a balance of power and regional correlation of forces which serves to deter any would-be aggressor nations. In the long run, the United States must seek a comprehensive regional peace. Various methods of achieving these goals are examined....Persian Gulf, Arms Proliferation, Strategic Planning, Gulf Cooperation Council, GCC, Regional Deterrence, Middle East, Arms Control, Scenario Development, Iraq, Iran, Saudi Arabia, Regional Security Strategy.

According to this hypothesis, happy employees exhibit higher levels of job-related performance behaviors than do unhappy employees. However, despite years of research, support for the happy–productive worker thesis remains equivocal. These ambiguous findings result from the variety of ways in which happiness has been operationalized.

A Proof of the Geroch-Horowitz-Penrose Formulation of the Strong Cosmic Censor Conjecture Motivated by Computability Theory  

NASA Astrophysics Data System (ADS)

In this paper we present a proof of a mathematical version of the strong cosmic censor conjecture attributed to Geroch-Horowitz and Penrose but formulated explicitly by Wald. The proof is based on the existence of future-inextendible causal curves in causal pasts of events on the future Cauchy horizon in a non-globally hyperbolic space-time. By examining explicit non-globally hyperbolic space-times we find that in case of several physically relevant solutions these future-inextendible curves have in fact infinite length. This way we recognize a close relationship between asymptotically flat or anti-de Sitter, physically relevant extendible space-times and the so-called Malament-Hogarth space-times which play a central role in recent investigations in the theory of "gravitational computers". This motivates us to exhibit a more sharp, more geometric formulation of the strong cosmic censor conjecture, namely "all physically relevant, asymptotically flat or anti-de Sitter but non-globally hyperbolic space-times are Malament-Hogarth ones". Our observations may indicate a natural but hidden connection between the strong cosmic censorship scenario and the Church-Turing thesis revealing an unexpected conceptual depth beneath both conjectures.

Quantum Algorithms: Applicable Algebra and Quantum Physics  

NASA Astrophysics Data System (ADS)

Classical computer science relies on the concept of Turing machines as a unifying model of universal computation. According to the modern Church-Turing Thesis, this concept is interpreted in the form that every physically reasonable model of computation can be efficiently simulated on a probabilistic Turing machine. Recently this understanding, which was taken for granted for a long time, has required a severe reorientation because of the emergence of new computers that do not rely on classical physics but, rather, use effects predicted by quantum mechanics.Quantum algorithms benefit from the application of the superposition principle to the internal states of the quantum computer, which are considered to be states in a (finite-dimensional) Hilbert space. As a result, these algorithms lead to a new theory of computation and might be of central importance to physics and computer science.We shall introduce the complexity model of quantum gates, which are most familiar to researchers in the field of quantum computing, and shall give many examples of the usefulness and conciseness of this formalism. Quantum circuits provide a computational model equivalent to quantum Turing machines.

Set theory and physics  

NASA Astrophysics Data System (ADS)

Inasmuch as physical theories are formalizable, set theory provides a framework for theoretical physics. Four speculations about the relevance of set theoretical modeling for physics are presented: the role of transcendental set theory (i) in chaos theory, (ii) for paradoxical decompositions of solid three-dimensional objects, (iii) in the theory of effective computability (Church-Turing thesis) related to the possible “solution of supertasks,” and (iv) for weak solutions. Several approaches to set theory and their advantages and disadvatages for physical applications are discussed: Canlorian “naive” (i.e., nonaxiomatic) set theory, contructivism, and operationalism. In the author's opinion, an attitude of “suspended attention” (a term borrowed from psychoanalysis) seems most promising for progress. Physical and set theoretical entities must be operationalized wherever possible. At the same time, physicists should be open to “bizarre” or “mindboggling” new formalisms, which need not be operationalizable or testable at the lime of their creation, but which may successfully lead to novel fields of phenomenology and technology.

RF Microalgal lipid content characterization  

PubMed Central

Most conventional techniques for the determination of microalgae lipid content are time consuming and in most cases are indirect and require excessive sample preparations. This work presents a new technique that utilizes radio frequency (RF) for rapid lipid quantification, without the need for sample preparation. Tests showed that a shift in the resonance frequency of a RF open-ended coaxial resonator and a gradual increase in its resonance magnitude may occur as the lipids content of microalgae cells increases. These response parameters can be then calibrated against actual cellular lipid contents and used for rapid determination of the cellular lipids. The average duration of lipid quantification using the proposed technique was of about 1 minute, which is significantly less than all other conventional techniques, and was achieved without the need for any time consuming treatment steps.

[Localisation of brain function, 125 years after the thesis of Aletta Jacobs, the first Dutch female physician].  

PubMed

Aletta H. Jacobs was the first female physician in the Netherlands. In 1879, she defended her thesis which addressed the subject of localising brain functions. In it she described three neurological patients using systematic conventions highly resembling those in use today. Moreover, she discussed whether or not functions were regionally represented. Her discussion concluded in favour of localisation. These days, the concept of distributed networks goes beyond simple topographical representation. This is illustrated in the cerebral organisation of vision. It is possible to discern visual centres that are specialised in processing specific qualities such as colour or visual motion. An additional feature of such segregated processing streams is the presence of underlying connections to specific brain areas at a distance. Functioning as a node in multiple networks, one single brain region may potentially be involved in multiple functions. This depends on the interactions with other regions and on the actual dominance of information processing within such networks. PMID:15771345

The application of the reduced order model Kalman filter to motion estimation of degraded image sequences. M.S. Thesis  

NASA Technical Reports Server (NTRS)

Motion estimation is a field of great interest because of its many applications in areas such as robotics and image coding. The optic flow method is one such scheme which, although fairly accurate, is prone to error in the presence of noise. This thesis describes the use of the reduced order model Kalman filter (ROMKF) in reducing errors in displacement estimation due to degradation of the sequence. The implementation of filtering and motion estimation algorithms on the SUN workstation is also discussed. Results from preliminary testing were used to determine the degrees of freedom available for the ROMKF in the SUN software. The tests indicated that increasing the state to the left leads to slight improvement over the minimum state case. Therefore, the software uses the minimum model, with the option of adding states to the left only. The ROMKF was then used in conjunction with a hierarchical pel recursive motion estimation algorithm. Applying the ROMKF to the degraded displacements themselves generally yielded slight improvements in cases with noise degradation and noise plus blur. Filtering the images of the degraded sequence prior to motion estimation was less effective in these cases. Both methods performed badly in the case of blur alone, resulting in increased displacement errors. This is thought to be due in part to filter artifacts. Some improvements were obtained by varying the filter parameters when filtering the displacements directly. This result suggests that further study in varying filter parameters may lead to better results. The results of this thesis indicate that the ROMKF can play a part in reducing motion estimation errors from degraded sequences. However, more work needs to be done before the use of the ROMKF can be a practical solution.

Studies on locus content mapping.  

PubMed

Locus content maps are derived from monosomic or disomic chromosomes broken by radiation, shearing, or other clastogen, the fragments being distributed among clones by dilution or incorporation into the cells of another species and scored for segregation of markers. Locus content maps provide evidence about radiosensitivity of chromosome regions, support for order, and approximate location. Omission of the most aberrant and least informative clones increases efficiency of localization. Correct analysis must allow for preferential retention of certain sequences, monosomy or polysomy of donor chromosomes, and error filtration. Combination of these refinements extracts substantially more information from fewer clones. Because of unmodeled peculiarities in the data, the best analysis does not recover the physical map but roughly localizes markers that may be monomorphic and therefore unsuitable for linkage mapping. As with linkage for polymorphic loci, distance in the composite map should be confirmed by physical methods. PMID:8876220

Selenium content of game meat  

SciTech Connect

Selenium (Se) content of elk, deer, bison and beef were measured and compared. Samples were obtained from animals grazed on soil known to contain high, but variable amounts of Se. Beef were feedlot grazed and elk, deer, and bison were from captive or semi-captive herds. Selenium content was determined by graphite furnace after high pressure wet microwave digestion of samples. Deer and bison contained more Se than elk or beef. On a dry weight basis, deer contained more Se than bison. Game species contained more Se than beef. Within samples from male elk and deer and elk and bison of both genders, there were interactions between specie and muscle effects. Muscle and gender did not significantly influence Se content. The animals from which these samples were taken were supplemented with feeds grown on high Se containing soils, which was reflected in all values. Se values were twofold higher than those previously reported for meat. Those consuming large quantities of game from areas with high Se soil may need to monitor Se intake to avoid consuming excessive quantities.

Stellar Content and Evolution of OB Associations  

NASA Astrophysics Data System (ADS)

An important goal in astronomy is to understand the star formation process. Studies thereof have led to fairly detailed theoretical knowledge of the formation of individual stars. However, there is no detailed understanding of the origin of global properties of the stellar population, such as the initial mass function. To constrain possible theories, studies of young stellar groups are required. OB associations near the Sun are excellent candidates. However, reliable membership determinations (based on proper motions) for OB associations are limited to spectral types earlier than B5. To remedy this problem the observation by HIPPARCOS of over 10,000 candidate members of OB associations within 1~kpc from the Sun was proposed. The results will be available by early 1996. To complement the HIPPARCOS data ground based studies have been carried out. These include the collection of photometry and the gathering of accurate radial velocities for the early type stars in Sco OB2. The combined data will lead to a much improved knowledge of the stellar content and internal kinematics of nearby OB associations. The aim of this thesis is to further investigate nearby OB associations by ground-based observations, to carry out a first analysis of the data from the radial velocity programme on Sco OB2, and to prepare for the release of HIPPARCOS data. The first part concerns the Orion OB1 association. Walraven photometry is presented of established and probable members of Orion OB1. The physical parameters of the stars are derived. These are used to determine the distance to the association, the ages of the subgroups, the depth of the molecular clouds along the line of sight, and the IMF. Using the derived IMF and the ages, the energy (in the form of stellar winds and supernovae) released into the interstellar medium by the stars in Orion OB1 is calculated. Next, the Orion-Eridanus bubble surrounding the association is investigated. Data on neutral hydrogen from the Leiden/Dwingeloo survey are combined with infrared (IRAS), CO (literature), and X-ray data (HEAO1). The neutral-hydrogen maps allow identification of the H I filaments and arcs delineating the Bubble and a derivation of the expansion velocity of the surrounding shell. The X-ray data are shown to anti-correlate in a detailed way with kinematically narrow features in H I. Comparison of IRAS 100 micron data with the H I data shows that the H I shell emission is optically thin, which justifies a derivation of its mass by direct conversion of the H I emission to column densities. Using a model that takes the density stratification of the Galactic H I layer into account, it is shown that the stellar winds and supernovae from Orion OB1 can account for the size as well as for the expansion velocity of the H I shell. The second part of the thesis concerns the radial velocity programme in Sco OB2. Observations for this programme were carried out with the CASPEC and ECHELEC echelle spectrographs at ESO, La Silla. The data reduction for ECHELEC spectra is described in detail. The differential wavelength calibration of the spectra is better than 0.25 km s^-1. From these spectra precise rotational velocities are derived for a sample of 156 stars that are established or probable members of Sco OB2. This sample is extended with literature data for 47 established members of Sco OB2. Analysis of the v sin i distributions shows that there are no significant differences between the subgroups of Sco OB2. It is shown that members of the binary population of Sco OB2 on the whole rotate more slowly than the single stars. Analysis of Walraven photometric colours shows that positions of B7-B9 single dwarfs above the main sequence of Sco OB2 are a consequence of rotation. The last part focuses on the preparation for the release of HIPPARCOS data. N-body models of OB associations are employed to investigate the reliability of so-called kinematic ages. These are the ages derived from proper motions, based on the model of linear expansion. It is shown that the tracing back of proper motions in time always

Annealing of defect sites in radiation damaged indium phosphide solar cells through laser illumination. Master`s thesis  

SciTech Connect

This thesis reports the results of a laser annealing technique used to remove defect sites from radiation damaged indium phosphide diffused junction solar cells. This involves the illumination of damaged solar cells with a continuous wave laser to produce a moderate heating and a large forward-biased current. The InP cells were irradiated with 27 MeV electrons to a given fluence, and tested for degradation. Light from an argon laser was used to illuminate each cell with an irradiance of 2.5 W/sq cm, producing a current density 7 to 10 times larger than under AMO conditions. Cells were annealed at 48.5 deg C, 60 deg C, and 75 deg C for periods of 15 to 60 minutes, and cooled to 25 deg C for power recovery determination. Annealing at 48.5 deg C resulted in a recovery of 17 to 18% of the power lost due to irradiation, and annealing cells at 60 deg C produced a recovery of 43 to 48%. A single test of the technique at 75 deg C produced a net recovery of only 21% of the power lost. These results indicate that significant power recovery results from the annealing of defects within InP solar cells. Continuing research should involve the repeating of the test at 75 deg C, and irradiations with electrons or protons of energies expected in the space environment.

Muslim oil and gas periphery; the future of hydrocarbons in Africa, southeast Asia and the Caspian. Master`s thesis  

SciTech Connect

This thesis is a study of the contemporary political, economic, and technical developments and future prospects of the Muslim hydrocarbon exporters of Africa, Southeast Asia, and the Caspian. The established Muslim oil and gas periphery of Africa and Southeast Asia has four members in the Organization of Petroleum Exporting Countries (OPEC) and is systemically increasing its production of natural gas. I analyze US government and corporate policies regarding the countries and the major dilemmas of the Muslim hydrocarbon periphery. The first chapter provides a selective overview of global energy source statistics; the policies, disposition and composition of the major hydrocarbon production and consumption players and communities; a selective background of OPEC and its impact on the globe; and a general portrait of how the Muslim periphery piece fits into the overall Muslim oil and gas puzzle. Chapter two analyzes the established Muslim oil and gas periphery of Africa and Southeast Asia asking the following questions: What are the major political, economic, and technical trends and dilemmas affecting these producer nations. And what are the United States` policies and relationships with these producers. Chapter three asks the same questions as chapter two, but with regard to the newly independent states of the Caspian Sea. I probe the regional petroleum exploration and transportation dilemmas in some detail.

The purpose of this thesis was to build a prototype decision aid that can use knowledge about Soviet military doctrine and tactics to infer when, where, and how the Soviet Army plans to attack NATO defenses given intelligence data about Soviet (Red) military units, terrain data, and the positions of the NATO (Blue) defenses. Issues are raised that must be resolved before such a decision aid, which is part of the Rapid Application of Air Power concept, can become operational. First examined is the need to shorten the C2 decision cycle in order for the ATOC staff to keep pace with the tempo of modern warfare. The Rapid Application of Air Power is a concept that includes automating various steps in the decision cycle to allow air power to be applied proactively to stop Soviet forces before they obtain critical objectives. A structure is presented for automating the second step in the decision cycle, assessing and clarifying the situation, through a knowledge-based decision aid for interpreting intelligence data from the perspective of Soviet (Red) doctrine and estimating future Red tactical objectives and maneuvers.

Optimization of a compton scatterer for hard x-ray weapons effects simulation in an ICF facility. Master's thesis  

SciTech Connect

This thesis examined the optimization of a Compton scatterer for use in simulating hard X-ray effects in the proposed Laboratory Microfusion Facility (LMF). The LMF will produce inertial confinement fusion of deuterium-tritium pellets. The Compton scatterer is designed to reflect the X rays produced from the fusion toward a target. The scatterer should produce the maximum X-ray dose at the target while minimizing the neutron dose and gamma production. The scatterer must also control the dose rate by spreading the X-ray pulse to achieve a full width at half maximum on the order of 10s of ns. The current geometry includes a spherical Compton scatterer made of lithium hydride enriched to 95.6% Lithium 6. This work explored various parabolic scatterers using Monte Carlo transport calculations performed on the MCNP computer program from Los Alamos National Lab. The parabolic shape was optimized to increased the X-ray dose at a silicone target by a factor of 7. The geometry also decreased the neutron and gamma doses to less than 1% of the X-ray dose while achieving an 80% uniformity of dose across a 1-meter-radius silicon disk.

A large motion zero-gravity suspension system for experimental simulation of orbital construction and deployment. M.S. Thesis  

NASA Technical Reports Server (NTRS)

The design and implementation of a vertical degree of freedom suspension system is described which provides a constant force off-load condition to counter gravity over large displacements. By accommodating motions up to one meter for structures weighing up to 100 pounds, the system is useful for experiments which simulate orbital construction events such as docking, multiple component assembly, or structural deployment. A unique aspect of this device is the combination of a large stroke passive off-load device augmented by electromotive torque actuated force feedback. The active force feedback has the effect of reducing break-away friction by a factor of twenty over the passive system alone. The thesis describes the development of the suspension hardware and the control algorithm. Experiments were performed to verify the suspensions system's effectiveness in providing a gravity off-load and simulating the motion of a structure in orbit. Additionally, a three dimensional system concept is presented as an extension of the one dimensional suspension system which was implemented.

Economic analysis of air-conditioning systems with off-peak chilled-water storage. Master's thesis  

SciTech Connect

This thesis investigates current methods of chilled-water storage for air conditioning applications and the economics of chilled-water storage with time-of-use electric utility rates. Current methods of chilled-water storage are investigated by comparing costs of construction materials for storage tanks and effectiveness and costs of anti-blending systems. The economics of chilled-water storage are analyzed by computing total life cycle costs of alternative air conditioning systems for two different sized buildings. Computer simulation is used to determine electric consumption for the buildings. The simulation of each building contains three options: no chilled-water storage, chiller operated only at night, and a small chiller supplemented by stored chilled-water. A gunite or Styrofoam tank with a moving partition anti-blending system is the least expensive and most effective storage system. The economics of chilled-water storage are sensitive to the size of the building analyzed. Operating the small chiller with supplemental chilled-water is economical in the smaller building. No chilled-water storage is the most economical option in the larger building. Operation of the chiller only at night was never economical.

Systematic method for the condition assessment of central heating plants in Air Force Logistics Command. Master's thesis  

SciTech Connect

Air Force Logistics Command (AFLC), facing decreasing funds and aging utility systems, needed a method to objectively rate its central heating plants. Such a rating system would be used to compare heating plants throughout the command to identify potential problem areas and prioritize major repair projects. This thesis used a Delphi questionnaire to gather opinions from heating plant experts in order to identify and prioritize components considered most critical to overall plant operation. In addition, the experts suggested measurements which could be used to evaluate component conditions. By combining expert opinions and reading from technical literature, component model rating schemes were developed for AFLC's steam and high temperature hot water plants. Based on measurements and observations of critical components in the plant, a score between 0 and 100 is assigned to each component (for example, condensate piping, deaerator, etc.), each plant subsystem (distribution system, water treatment system, etc.), and to the plant as a whole. These component model rating schemes and the resultant overall condition index scores will enable AFLC to focus their management attention and allocate needed resources to the plants in greatest need of repair.

Identification of barriers to more-effective agricultural water management in the Salinas River Valley. Master's thesis  

SciTech Connect

The Salinas River Valley is currently in its fifth straight year of drought. Groundwater is becoming increasingly more important to the economic future of this agriculturally dominated valley. Continued consumption of groundwater at the current rate threatens the economic and environmental future of the Valley through excessive overdrafting of the underlying aquifer and through the phenomenon of seawater intrusion. This thesis identifies the physical, economic, social and political barriers to more effective agricultural water management from the perspective of the individual grower, through the use of a comprehensive survey. This study will contribute to a better understanding of the major water conservation issues and barriers from the individual grower's perspective. It will provide useful information to decision makers in arriving at water conservation policies that are both equitable and in the best long term interest of the various water users of the Salinas River Valley. By exploring the multiple dimensions of specific issues, the perceived and real barriers and the perceptions of interested parties, this study will help foster better awareness, cooperation and communications between he county agency responsible for water resources management and the individual agricultural growers.

Caffeine content of decaffeinated coffee.  

PubMed

Caffeine is the most widely consumed drug in the world with coffee representing a major source of intake. Despite widespread availability, various medical conditions necessitate caffeine-restricted diets. Patients on certain prescription medications are advised to discontinue caffeine intake. Such admonition has implications for certain psychiatric patients because of pharmacokinetic interactions between caffeine and certain anti-anxiety drugs. In an effort to abstain from caffeine, patients may substitute decaffeinated for caffeinated coffee. However, decaffeinated beverages are known to contain caffeine in varying amounts. The present study determined the caffeine content in a variety of decaffeinated coffee drinks. In phase 1 of the study, 10 decaffeinated samples were collected from different coffee establishments. In phase 2 of the study, Starbucks espresso decaffeinated (N=6) and Starbucks brewed decaffeinated coffee (N=6) samples were collected from the same outlet to evaluate variability of caffeine content of the same drink. The 10 decaffeinated coffee samples from different outlets contained caffeine in the range of 0-13.9 mg/16-oz serving. The caffeine content for the Starbucks espresso and the Starbucks brewed samples collected from the same outlet were 3.0-15.8 mg/shot and 12.0-13.4 mg/16-oz serving, respectively. Patients vulnerable to caffeine effects should be advised that caffeine may be present in coffees purported to be decaffeinated. Further research is warranted on the potential deleterious effects of consumption of "decaffeinated" coffee that contains caffeine on caffeine-restricted patients. Additionally, further exploration is merited for the possible physical dependence potential of low doses of caffeine such as those concentrations found in decaffeinated coffee. PMID:17132260

Content of system design descriptions  

SciTech Connect

A System Design Description (SDD) describes the requirements and features of a system. This standard provides guidance on the expected technical content of SDDs. The need for such a standard was recognized during efforts to develop SDDs for safety systems at DOE Hazard Category 2 nonreactor nuclear facilities. Existing guidance related to the corresponding documents in other industries is generally not suitable to meet the needs of DOE nuclear facilities. Across the DOE complex, different contractors have guidance documents, but they vary widely from site to site. While such guidance documents are valuable, no single guidance document has all the attributes that DOE considers important, including a reasonable degree of consistency or standardization. This standard is a consolidation of the best of the existing guidance. This standard has been developed with a technical content and level of detail intended to be most applicable to safety systems at DOE Hazard Category 2 nonreactor nuclear facilities. Notwithstanding that primary intent, this standard is recommended for other systems at such facilities, especially those that are important to achieving the programmatic mission of the facility. In addition, application of this standard should be considered for systems at other facilities, including non-nuclear facilities, on the basis that SDDs may be beneficial and cost-effective.

Fluoride content of infant foods.  

PubMed

Excessive fluoride consumption during the first 2 years of life is associated with an increased risk of dental fluorosis. Estimates of fluoride intake from various sources may aid in determining a child's risk for developing fluorosis. This study sought to assess the fluoride content of commercially available foods for infants, and to guide dentists who are advising parents of young children about fluoride intake. Three samples each of 20 different foods (including fruits and vegetables, as well as chicken, turkey, beef/ham, and vegetarian dinners) from 3 manufacturers were analyzed (in duplicate) for their fluoride content. Among the 360 samples tested, fluoride concentration ranged from 0.007-4.13 ?g fluoride/g food. All foods tested had detectable amounts of fluoride. Chicken products had the highest mean levels of fluoride, followed by turkey products. Consuming >1 serving per day of the high fluoride concentration products in this study would place children over the recommended daily fluoride intake. Fluoride from infant foods should be taken into account when determining total daily fluoride intake. PMID:24598501

Inverse statistics and information content  

NASA Astrophysics Data System (ADS)

Inverse statistics analysis studies the distribution of investment horizons to achieve a predefined level of return. This distribution provides a maximum investment horizon which determines the most likely horizon for gaining a specific return. There exists a significant difference between inverse statistics of financial market data and a fractional Brownian motion (fBm) as an uncorrelated time-series, which is a suitable criteria to measure information content in financial data. In this paper we perform this analysis for the DJIA and S&P500 as two developed markets and Tehran price index (TEPIX) as an emerging market. We also compare these probability distributions with fBm probability, to detect when the behavior of the stocks are the same as fBm.

[The nitrate content in milk].  

PubMed

Analytical possibilities for nitrate determination in milk on the base of photometric methods are discussed. An automated method, similar to Nijhuis u. a. (1979), is proposed using flow stream analyser ADM 300. Natrium nitrate (5 g and 10 g/kg live weight resp.) was given to two dairy cows after morning feeding on the 1st and on the 3rd day of experiment. The increase of nitrate content in the milk was very quick, maximal concentrations after 2 h were found as 5.6 mg/l (animal 1) and 3.2 mg nitrate-N/l (animal 2). But nitrate also disappeared relatively quickly, after 24 h there only values were observed corresponding to normal range of 1 mg/l. PMID:1953343

Antiparticle content in the magnetosphere  

NASA Astrophysics Data System (ADS)

In the present work we assess the stable and transient antiparticle content of planetary magnetospheres, and subsequently we consider their capture and application to high delta-v space propulsion. We estimate the total antiparticle mass contained within the Earth’s magnetosphere to assess the expediency of such usage. Using Earth’s magnetic field region as an example, we have considered the various source mechanisms that are applicable to a planetary magnetosphere, the confinement duration versus transport processes, and the antiparticle loss mechanisms. We have estimated the content of the trapped population of antiparticles magnetically confined following production in the exosphere due to nuclear interactions between high energy cosmic rays (CR) and constituents of the residual planetary upper atmosphere. The galactic antiprotons that directly penetrate into the Earth’s magnetosphere are themselves secondary by its nature, i.e. produced in nuclear reactions of the cosmic rays passing through the interstellar matter. These antiproton fluxes are modified, dependent on energy, when penetrating into the heliosphere and subsequently into planetary magnetospheres. During its lifetime in the Galaxy, CR pass through the small grammage of the interstellar matter where they produce secondary antiprotons. In contrast to this, antiprotons generated by the same CR in magnetosphere are locally produced at a path length of several tens g/cm2 of matter in the ambient planetary upper atmosphere. Due to the latter process, the resulting magnetically confined fluxes significantly exceed the fluxes of the galactic antiprotons in the Earth’s vicinity by up to two orders of magnitude at some energies. The radiation belt antiparticles can possibly be extracted with an electromagnetic-based “scoop” device. The antiparticles could be concentrated by and then stored within the superimposed magnetic field structure of such a device. In future developments, it is anticipated that the energy of the captured antiparticles (both rest energy and kinetic energy) can be adapted for use as a fuel for propelling spacecraft to high velocities for remote solar system missions.

The pathology informatics curriculum wiki: Harnessing the power of user-generated content  

PubMed Central

Background: The need for informatics training as part of pathology training has never been so critical, but pathology informatics is a wide and complex field and very few programs currently have the resources to provide comprehensive educational pathology informatics experiences to their residents. In this article, we present the “pathology informatics curriculum wiki”, an open, on-line wiki that indexes the pathology informatics content in a larger public wiki, Wikipedia, (and other online content) and organizes it into educational modules based on the 2003 standard curriculum approved by the Association for Pathology Informatics (API). Methods and Results: In addition to implementing the curriculum wiki at http://pathinformatics.wikispaces.com, we have evaluated pathology informatics content in Wikipedia. Of the 199 non-duplicate terms in the API curriculum, 90% have at least one associated Wikipedia article. Furthermore, evaluation of articles on a five-point Likert scale showed high scores for comprehensiveness (4.05), quality (4.08), currency (4.18), and utility for the beginner (3.85) and advanced (3.93) learners. These results are compelling and support the thesis that Wikipedia articles can be used as the foundation for a basic curriculum in pathology informatics. Conclusions: The pathology informatics community now has the infrastructure needed to collaboratively and openly create, maintain and distribute the pathology informatics content worldwide (Wikipedia) and also the environment (the curriculum wiki) to draw upon its own resources to index and organize this content as a sustainable basic pathology informatics educational resource. The remaining challenges are numerous, but largest by far will be to convince the pathologists to take the time and effort required to build pathology informatics content in Wikipedia and to index and organize this content for education in the curriculum wiki.

Protonospheric columnar electron content determination. II - Observations  

NASA Technical Reports Server (NTRS)

The results of over 300 hours of measurements of the quantity I sub w - the difference between total columnar electron content, derived from the differential phase-path data, and Faraday electron content - is presented. The interpretation of the measurements in terms of protonospheric content is discussed in the light of a previous analysis which demonstrates that good protonospheric content measurements can only be obtained under certain geometries of observations unless information on the shape and height of the ionospheric layer is available. A strong correlation between I sub w and the ionospheric content is observed in most of the Arecibo data, because they were collected under unfavorable conditions. The Stanford data, on the other hand, yield good measurements of the protonospheric content. The May 1969 observations show a strong depletion of protonospheric content during a magnetic storm and its subsequent recovery. This is in general agreement with flux tube content behavior observed by the whistler technique during similar conditions.

MPEG-7: standard metadata for multimedia content  

NASA Astrophysics Data System (ADS)

The eXtensible Markup Language (XML) metadata technology of describing media contents has emerged as a dominant mode of making media searchable both for human and machine consumptions. To realize this premise, many online Web applications are pushing this concept to its fullest potential. However, a good metadata model does require a robust standardization effort so that the metadata content and its structure can reach its maximum usage between various applications. An effective media content description technology should also use standard metadata structures especially when dealing with various multimedia contents. A new metadata technology called MPEG-7 content description has merged from the ISO MPEG standards body with the charter of defining standard metadata to describe audiovisual content. This paper will give an overview of MPEG-7 technology and what impact it can bring forth to the next generation of multimedia indexing and retrieval applications.

Toxicity of polychlorinated diphenyl ethers in hydra attenuata and in rat whole-embryo culture. Master's thesis  

SciTech Connect

Polychlorinated diphenyl ethers (PCDEs) are a class of biaryl compounds that have little commercial application, but appear to be widespread in the environment. They have been found in wood preservative waste dumpsites and in fly ash from municipal waste incinerators. They have been detected in bird eggs and tissues, fish, and other edible marine organisms in the United States, Canada, and Europe. There are limited reports in the extant literature on the toxicity of PCDEs. This study was designed to evaluate the toxicity of selected PCDEs in cultures of Hydra attenuata and post-implantation rat whole embryos. The toxicity of several closely related polychlorinated biphenyls (PCBs) was evaluated in both cultures and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) was evaluated in whole embryo culture. Embryonic growth and development parameters (yolk sac diameter, crown-rump length, somite count, and DNA and protein content) and gross morphology were determined. Findings indicated that these chemicals were neither embryotoxic nor teratogenic. Thus, the PCDEs, which elicit other diverse toxic and biochemical responses in rodents, are relatively inactive in these bioassays for developmental toxicity.

MC carbide structures in M(lc2)ar-M247. M.S. Thesis - Final Report  

NASA Technical Reports Server (NTRS)

The morphologies and distribution of the MC carbides in Mar-M247 ingot stock and castings were investigated using metallographic, X-ray diffraction and energy-dispersive X-ray analysis techniques. The MC carbides were found to form script structures during solidification. The script structures were composed of three distinct parts. The central cores and elongated arms of the MC carbide script structures had compositions (Ti, Cr, Hf, Ta, W)C and lattice parameters of 4.39 A. The elongated script arms terminated in enlarged, angular "heads". The heads had compositions (Ti, Hf, Ta, W)C and lattice parameters of approximately 4.50 A. The heads had a higher Hf content than the cores and arms. The size of the script structures, as well as the relative amount of head-type to core and arm-type MC carbide, was found to be determined by solidification conditions. No carryover of the MC carbides from the ingot stock to the remelted and cast material was observed.

Experimental and analytical investigation of a freezing point depressant fluid ice protection system. M.S. Thesis. Final Report  

NASA Technical Reports Server (NTRS)

A glycol-exuding porous leading edge ice protection system was tested in the NASA Icing Research Tunnel. Stainless steel mesh, laser drilled titanium, and composite panels were tested on two general aviation wing sections. Two different glycol-water solutions were evaluated. Minimum glycol flow rates required for anti-icing were obtained as a function of angle of attack, liquid water content, volume median drop diameter, temperature, and velocity. Ice accretions formed after five minutes of icing were shed in three minutes or less using a glycol fluid flow equal to the anti-ice flow rate. Two methods of predicting anti-ice flow rates are presented and compared with a large experimental data base of anti-ice flow rates over a wide range of icing conditions. The first method presented in the ADS-4 document typically predicts flow rates lower than the experimental flow rates. The second method, originally published in 1983, typically predicts flow rates up to 25 percent higher than the experimental flow rates. This method proved to be more consistent between wing-panel configurations. Significant correlation coefficients between the predicted flow rates and the experimental flow rates ranged from .867 to .947.

Psychometrics of A New Questionnaire to Assess Glaucoma Adherence: The Glaucoma Treatment Compliance Assessment Tool (An American Ophthalmological Society Thesis)  

PubMed Central

Purpose: To report the psychometrics of the Glaucoma Treatment Compliance Assessment Tool (GTCAT), a new questionnaire designed to assess adherence with glaucoma therapy. Methods: We developed the questionnaire according to the constructs of the Health Belief Model. We evaluated the questionnaire using data from a cross-sectional study with focus groups (n = 20) and a prospective observational case series (n=58). Principal components analysis provided assessment of construct validity. We repeated the questionnaire after 3 months for test-retest reliability. We evaluated predictive validity using an electronic dosing monitor as an objective measure of adherence. Results: Focus group participants provided 931 statements related to adherence, of which 88.7% (826/931) could be categorized into the constructs of the Health Belief Model. Perceived barriers accounted for 31% (288/931) of statements, cues-to-action 14% (131/931), susceptibility 12% (116/931), benefits 12% (115/931), severity 10% (91/931), and self-efficacy 9% (85/931). The principal components analysis explained 77% of the variance with five components representing Health Belief Model constructs. Reliability analyses showed acceptable Cronbach’s alphas (>.70) for four of the seven components (severity, susceptibility, barriers [eye drop administration], and barriers [discomfort]). Predictive validity was high, with several Health Belief Model questions significantly associated (P <.05) with adherence and a correlation coefficient (R2) of .40. Test-retest reliability was 90%. Conclusion: The GTCAT shows excellent repeatability, content, construct, and predictive validity for glaucoma adherence. A multisite trial is needed to determine whether the results can be generalized and whether the questionnaire accurately measures the effect of interventions to increase adherence.

Ultrasound assessment of gastric content and volume.  

PubMed

Pulmonary aspiration of gastric content is a serious anaesthetic complication that can lead to significant morbidity and mortality. Aspiration risk assessment is usually based on fasting times. However, fasting guidelines do not apply to urgent or emergent situations and to patients with certain co-morbidities. Gastric content and volume assessment is a new point-of-care ultrasound application that can help determine aspiration risk. This systematic review summarizes the current literature on bedside ultrasound assessment of gastric content and volume relevant to anaesthesia practice. Seventeen articles were identified using predetermined criteria. Studies were classified into those describing the sonographic characteristics of different types of gastric content (empty, clear fluid, solid), and those describing methods for quantitative assessment of gastric volume. A possible algorithm for the clinical application of this new tool is proposed, and areas that require further research are highlighted. PMID:24893784

Crossroads in Mathematics: Standards for Content  

NSDL National Science Digital Library

This section of Crossroads in Mathematics, a guideline for improving introductory postsecondary mathematics courses, outlines the standards for the content of mathematics courses. While mathematical content has traditionally been the focus of curriculum development, this document takes the view that "knowing mathematics means being able to do mathematics and that problem solving is the heart of doing mathematics. The successful problem solver can view the world from a mathematical perspective." The section outlines and describes seven integral content areas of an introductory mathematics course: number sense, symbolism and algebra, geometry, function, discrete mathematics, probability and statistics, and deductive proof. The document will benefit educators and administrators alike to enhance the content of any mathematics course and help students understand the meaning and use of mathematics beyond rote memorization.

Intelligent content fitting for digital publishing  

NASA Astrophysics Data System (ADS)

One recurring problem in Variable Data Printing (VDP) is that the existing contents cannot satisfy the VDP task as-is. So there is a strong need for content fitting technologies to support high-value digital publishing applications, in which text and image are the two major types of contents. This paper presents meta-Autocrop framework for image fitting and TextFlex technology for text fitting. The meta-Autocrop framework supports multiple modes: fixed aspect-ratio mode, advice mode, and verification mode. The TextFlex technology supports non-rectangular text wrapping and paragraph-based line breaking. We also demonstrate how these content fitting technologies are utilized in the overall automated composition and layout system.

Numerical Prediction of Turbulent Oscillating Flow and Heat Transfer in Pipes with Various End Geometries. Ph.D. Thesis, Final Report  

NASA Technical Reports Server (NTRS)

Unsteady flow is present in man, machine and nature. The flow of blood in arteries and capillaries in the human body is pulsatile-composed of a mean flow superposed with an oscillating component. The tides that wash in and out of rivers, harbors and estuaries are unsteady flows with very long periods of oscillation. Many engineering devices employ pulsatile and oscillating flow. Pulsating flow is defined here as a periodic flow with a net displacement of fluid over each flow cycle. Oscillating flow is defined as a period flow with a zero mean over each cycle. The subject of this thesis is oscillating flow and heat transfer in pipes which make up the heater and cooler sections of the NASA Space Power Research Engine (SPRE) currently under development. This engine uses the Stirling cycle as the thermal energy converter in a power plant for future space applications. The information presented in this thesis will of course be applicable to the design of many types of machinery which employ oscillating flow and heat transfer.

Remote-Handled Transuranic Content Codes  

SciTech Connect

The Remote-Handled Transuranic (RH-TRU) Content Codes (RH-TRUCON) document representsthe development of a uniform content code system for RH-TRU waste to be transported in the 72-Bcask. It will be used to convert existing waste form numbers, content codes, and site-specificidentification codes into a system that is uniform across the U.S. Department of Energy (DOE) sites.The existing waste codes at the sites can be grouped under uniform content codes without any lossof waste characterization information. The RH-TRUCON document provides an all-encompassing|description for each content code and compiles this information for all DOE sites. Compliance withwaste generation, processing, and certification procedures at the sites (outlined in this document foreach content code) ensures that prohibited waste forms are not present in the waste. The contentcode gives an overall description of the RH-TRU waste material in terms of processes and|packaging, as well as the generation location. This helps to provide cradle-to-grave traceability ofthe waste material so that the various actions required to assess its qualification as payload for the72-B cask can be performed. The content codes also impose restrictions and requirements on themanner in which a payload can be assembled.The RH-TRU Waste Authorized Methods for Payload Control (RH-TRAMPAC), Appendix 1.3.7of the 72-B Cask Safety Analysis Report (SAR), describes the current governing procedures|applicable for the qualification of waste as payload for the 72-B cask. The logic for this|classification is presented in the 72-B Cask SAR. Together, these documents (RH-TRUCON,|RH-TRAMPAC, and relevant sections of the 72-B Cask SAR) present the foundation and|justification for classifying RH-TRU waste into content codes. Only content codes described in thisdocument can be considered for transport in the 72-B cask. Revisions to this document will be madeas additional waste qualifies for transport. |Each content code uniquely identifies the generated waste and provides a system for tracking theprocess and packaging history. Each content code begins with a two-letter site abbreviation thatindicates the shipper of the RH-TRU waste. The site-specific letter designations for each of the|DOE sites are provided in Table 1. Not all of the sites listed in Table 1 have generated/stored RH-|TRU waste.

Policosanol contents and compositions of wheat varieties.  

PubMed

Policosanol (PC) is the common name for a mixture of high molecular weight (20-36 carbon) aliphatic primary alcohols, which are constituents of plant epicuticular waxes. Wheat germ oil has been reported to improve human physical fitness, and this effect is attributed to its high PC, specifically its high octacosanol (OC) content. Although the PC composition of wheat leaves has been studied extensively, information on PC content and composition of wheat grain fractions is scarce. The objective of this study was to examine the PC contents and compositions of wheat grain fractions of 31 varieties grown in Oklahoma. PC compositions of the samples were identified using a gas chromatograph coupled with a mass spectrometer. The PC content of wheat bran was higher than that of the germ, shorts, and flour. The Trego and Intrada varieties had the highest PC content among the 31 wheat varieties studied. Tetracosanol (C24), hexacosanol (C26), and OC (C28) were the major PC components in all varieties. This study showed that wheat varieties grown under identical growing conditions and management differ significantly in PC content and composition. PMID:15998118

Analyzing Contents of a Computer Cache  

NASA Technical Reports Server (NTRS)

The Cache Contents Estimator (CCE) is a computer program that provides information on the contents of level-1 cache of a PowerPC computer. The CCE is configurable to enable simulation of any processor in the PowerPC family. The need for CCE arises because the contents of level-1 caches are not available to either hardware or software readout mechanisms, yet information on the contents is crucial in the development of fault-tolerant or highly available computing systems and for realistic modeling and prediction of computing- system performance. The CCE comprises two independent subprograms: (1) the Dynamic Application Address eXtractor (DAAX), which extracts the stream of address references from an application program undergoing execution and (2) the Cache Simulator (CacheSim), which models the level-1 cache of the processor to be analyzed, by mimicking what the cache controller would do, in response to the address stream from DAAX. CacheSim generates a running estimate of the contents of the data and the instruction subcaches of the level-1 cache, hit/miss ratios, the percentage of cache that contains valid or active data, and time-stamped histograms of the cache content.

Are delusional contents replayed during dreams?  

PubMed

The relationship between dream content and waking life experiences remains difficult to decipher. However, some neurobiological findings suggest that dreaming can, at least in part, be considered epiphenomenal to ongoing memory consolidation processes in sleep. Both abnormalities in sleep architecture and impairment in memory consolidation mechanisms are thought to be involved in the development of psychosis. The objective of this study was to assess the continuity between delusional contents and dreams in acutely psychotic patients. Ten patients with a single fixed and recurring delusional content were asked to report their dreams during an acute psychotic break. Sixteen judges with four different levels of acquaintance to the specific content of the patients' delusions were asked to group the dreams, expecting that fragments of the delusional thought would guide the task. A mathematical index (f,t) was developed in order to compare correct groupings between the four groups of judges. Most judges grouped the dreams slightly above chance level and no relevant differences could be found between the four groups [F(3,12)=1.297; p=n.s.]. Scoring of dreams for specific delusional themes suggested a continuity in terms of dream and waking mentation for two contents (Grandiosity and Religion). These findings seem to suggest that at least some delusional contents recur within patients' dreams. Future studies will need to determine whether such continuity reflects ongoing consolidation processes that are relevant to current theories of delusion formation and stabilization. PMID:23703023

Energy content of municipal solid waste bales.  

PubMed

Baling technology is a preferred method for temporary storage of municipal solid waste (MSW) prior to final disposal. If incineration is intended for final disposal of the bales, the energy content of the baled MSW gains importance. In this study, nine cylindrical bales containing a mix of different waste materials were constructed and several parameters, including total carbon (TC), total organic carbon (TOC), total Kjeldahl nitrogen, moisture content, loss on ignition, gross calorific value and net calorific value (NCV) were determined before the baling and at the end of 10 months of storage. In addition, the relationships between the waste materials and the energy contents of the bales were investigated by the bivariate correlation analyses. At the end, linear regression models were developed in order to forecast the decrease of energy content during storage. While the NCVs of the waste materials before the baling ranged between 6.2 and 23.7 MJ kg(-1) dry basis, they ranged from 1.0 to 16.4 MJ kg(-1) dry basis at the end of the storage period. Moreover, food wastes exhibited the highest negative correlation with NCVs, whereas plastics have significant positive correlation with both NCVs and TCs. Similarly, TOCs and carbon/nitrogen ratios decreased with the increase in food amounts inside the bales. In addition, textile, wood and yard wastes increase the energy content of the bales slightly over the storage period. PMID:23615510

Spatial watermark for image content authentication  

NASA Astrophysics Data System (ADS)

This paper is focused on digital image authentication, considered as the process of evaluating the integrity of image contents relatively to the original picture and being able to detect, in an automatic way, malevolent content modifications. A computationally efficient spatial watermarking technique for authentication of visual information, robust to small distortions caused by compression, is described. In essence, content-dependent authentication data are embedded into the picture, by modifying the relationship of image projections throughout the entire image. To obtain a secure data embedding and extraction procedure, directions onto which image parts are projected depend on a secret key. In order to guarantee minimum visibility of the embedded data, the insertion process is used in conjunction with perceptual models, exploiting spatial domain masking effects. The viability of the method as a means of protecting the content is assessed under JPEG compression and semantic content modifications. With the present system, robustness to JPEG compression up to compression factors of about 1:10 can be achieved, maintaining the subjective image quality after watermark insertion. At the same time, it is possible to detect and localize small image manipulations.

Protonospheric columnar electron content determination. I - Analysis.  

NASA Technical Reports Server (NTRS)

A combination of phase-path length difference and Faraday rotation angle data obtained from geostationary satellite transmissions is used to determine the integration constant necessary to convert phase-path length difference information into absolute values of total slant columnar electron content. The total content thus determined, which is the sum of the ionospheric and protonospheric contents, is measured with uncertainties about one order of magnitude smaller than the value of the protonospheric content. It is thus, in principle, possible to determine the latter by subtracting from the measurement the so-called 'Faraday content.' This idea, proposed by several authors in the past, is critically examined in the present paper. It is impossible to totally eliminate the ionospheric contribution to the measurements; however, it is shown that the degree of elimination depends on the type of distribution of the longitudinal component of the geomagnetic field along the path of observation. Satisfactory minimization of the ionospheric contribution can be accomplished only under certain geometries of observation.

Content Sharing in User Binding DRM  

NASA Astrophysics Data System (ADS)

Content sharing mechanisms in current DRM systems are based on a domain where multiple devices have the same domain key. This can lead to a security weakness as failure of one device means revocation of a domain itself. Furthermore, if a device leaves the domain, all the other devices should update their domain key. This also leads to efficiency problem. This paper proposes the new content sharing scheme based on the user binding DRM without the use of domain key. The proposed scheme improves the previous domain technology in terms of security and efficiency as it removes the use of domain key and only allows content sharing for multiple devices owned by the same user.

Quantitative Measurements of Autobiographical Memory Content  

PubMed Central

Autobiographical memory (AM), subjective recollection of past experiences, is fundamental in everyday life. Nevertheless, characterization of the spontaneous occurrence of AM, as well as of the number and types of recollected details, remains limited. The CRAM (Cue-Recalled Autobiographical Memory) test (http://cramtest.info) adapts and combines the cue-word method with an assessment that collects counts of details recalled from different life periods. The SPAM (Spontaneous Probability of Autobiographical Memories) protocol samples introspection during everyday activity, recording memory duration and frequency. These measures provide detailed, naturalistic accounts of AM content and frequency, quantifying essential dimensions of recollection. AM content (?20 details/recollection) decreased with the age of the episode, but less drastically than the probability of reporting remote compared to recent memories. AM retrieval was frequent (?20/hour), each memory lasting ?30 seconds. Testable hypotheses of the specific content retrieved in a fixed time from given life periods are presented.

Video databases: automatic retrieval based on content.  

NASA Astrophysics Data System (ADS)

Digital video databases are becoming more and more pervasive and finding video of interest in large databases is rapidly becoming a problem. Intelligent means of quick content-based video retrieval and content-based rapid video viewing is, therefore, an important topic of research. Video is a rich source of data, it contains visual and audio information, and in many cases, there is text associated with the video. Content-based video retrieval should use all this information in an efficient and effective way. From a human perspective, a video query can be viewed as an iterated sequence of navigating, searching, browsing, and viewing. This paper addresses video search in terms of these phases.

NASA Technical Reports Server (NTRS)

There exists a large number of large-scale bibliographic Information Storage and Retrieval Systems containing large amounts of valuable data of interest in a wide variety of research applications. These systems are not used to capacity because the end users, i.e., the researchers, have not been trained in the techniques of accessing such systems. This thesis describes the development of a transportable, university-level course in methods of querying on-line interactive Information Storage and Retrieval systems as a solution to this problem. This course was designed to instruct upper division science and engineering students to enable these end users to directly access such systems. The course is designed to be taught by instructors who are not specialists in either computer science or research skills. It is independent of any particular IS and R system or computer hardware. The project is sponsored by NASA and conducted by the University of Southwestern Louisiana and Southern University.

Computational strategies for three-dimensional flow simulations on distributed computer systems. Ph.D. Thesis Semiannual Status Report, 15 Aug. 1993 - 15 Feb. 1994  

NASA Technical Reports Server (NTRS)

An increasing amount of research activity in computational fluid dynamics has been devoted to the development of efficient algorithms for parallel computing systems. The increasing performance to price ratio of engineering workstations has led to research to development procedures for implementing a parallel computing system composed of distributed workstations. This thesis proposal outlines an ongoing research program to develop efficient strategies for performing three-dimensional flow analysis on distributed computing systems. The PVM parallel programming interface was used to modify an existing three-dimensional flow solver, the TEAM code developed by Lockheed for the Air Force, to function as a parallel flow solver on clusters of workstations. Steady flow solutions were generated for three different wing and body geometries to validate the code and evaluate code performance. The proposed research will extend the parallel code development to determine the most efficient strategies for unsteady flow simulations.

Checkpoint-based forward recovery using lookahead execution and rollback validation in parallel and distributed systems. Ph.D. Thesis, 1992  

NASA Technical Reports Server (NTRS)

This thesis studies a forward recovery strategy using checkpointing and optimistic execution in parallel and distributed systems. The approach uses replicated tasks executing on different processors for forwared recovery and checkpoint comparison for error detection. To reduce overall redundancy, this approach employs a lower static redundancy in the common error-free situation to detect error than the standard N Module Redundancy scheme (NMR) does to mask off errors. For the rare occurrence of an error, this approach uses some extra redundancy for recovery. To reduce the run-time recovery overhead, look-ahead processes are used to advance computation speculatively and a rollback process is used to produce a diagnosis for correct look-ahead processes without rollback of the whole system. Both analytical and experimental evaluation have shown that this strategy can provide a nearly error-free execution time even under faults with a lower average redundancy than NMR.

10Be contents of SNC meteorites  

NASA Astrophysics Data System (ADS)

Several authors have explored the possibility that the Shergottites, Nakhlites, and Chassigny (SNC) came from Mars. The spallogenic gas contents of the SNC meteorites have been used to: constrain the sizes of the SNC's during the last few million years; to establish groupings independent of the geochemical ones; and to estimate the likelihood of certain entries in the catalog of all conceivable passages from Mars to Earth. The particular shielding dependence of Be-10 makes the isotope a good probe of the irradiation conditions experienced by the SNC meteorites. The Be-10 contents of nine members of the group were measured using the technique of accelerator mass spectrometry. The Be-10 contents of Nakhla, Governador Valadares, Chassigny, and probably Lafayette, about 20 dpm/kg, exceed the values expected from irradiation of the surface of a large body. The Be-10 data therfore do not support scenario III of Bogard et al., one in which most of the Be-10 in the SNC meteorites would have formed on the Martian surface; they resemble rather the Be-10 contents found in many ordinary chondrites subjected to 4 Pi exposures. The uncertainties of the Be-10 contents lead to appreciable errors in the Be-10 ages, t(1) = -1/lambda ln(1 Be-10/Be-10). Nonetheless, the Be-10 ages are consistent with the Ne-21 ages calculated assuming conventional, small-body production rates and short terrestrial ages for the finds. It is believed that this concordance strengthens the case for at least 3 different irradiation ages for the SNC meteorites. Given the similar half-thicknesses of the Be-10 and Ne-21 production rates, the ratios of the Be-10 and Ne-21 contents do not appear consistent with common ages for any of the groups. In view of the general agreement between the Be-10 and Ne-21 ages it does not seem useful at this time to construct multiple-stage irradiation histories for the SNC meteorites.

Sugarcane genes associated with sucrose content  

PubMed Central

Background - Sucrose content is a highly desirable trait in sugarcane as the worldwide demand for cost-effective biofuels surges. Sugarcane cultivars differ in their capacity to accumulate sucrose and breeding programs routinely perform crosses to identify genotypes able to produce more sucrose. Sucrose content in the mature internodes reach around 20% of the culms dry weight. Genotypes in the populations reflect their genetic program and may display contrasting growth, development, and physiology, all of which affect carbohydrate metabolism. Few studies have profiled gene expression related to sugarcane's sugar content. The identification of signal transduction components and transcription factors that might regulate sugar accumulation is highly desirable if we are to improve this characteristic of sugarcane plants. Results - We have evaluated thirty genotypes that have different Brix (sugar) levels and identified genes differentially expressed in internodes using cDNA microarrays. These genes were compared to existing gene expression data for sugarcane plants subjected to diverse stress and hormone treatments. The comparisons revealed a strong overlap between the drought and sucrose-content datasets and a limited overlap with ABA signaling. Genes associated with sucrose content were extensively validated by qRT-PCR, which highlighted several protein kinases and transcription factors that are likely to be regulators of sucrose accumulation. The data also indicate that aquaporins, as well as lignin biosynthesis and cell wall metabolism genes, are strongly related to sucrose accumulation. Moreover, sucrose-associated genes were shown to be directly responsive to short term sucrose stimuli, confirming their role in sugar-related pathways. Conclusion - Gene expression analysis of sugarcane populations contrasting for sucrose content indicated a possible overlap with drought and cell wall metabolism processes and suggested signaling and transcriptional regulators to be used as molecular markers in breeding programs. Transgenic research is necessary to further clarify the role of the genes and define targets useful for sugarcane improvement programs based on transgenic plants.

Remote-Handled Transuranic Content Codes  

SciTech Connect

The Remote-Handled Transuranic (RH-TRU) Content Codes (RH-TRUCON) document describes the inventory of RH-TRU waste within the transportation parameters specified by the Remote-Handled Transuranic Waste Authorized Methods for Payload Control (RH-TRAMPAC).1 The RH-TRAMPAC defines the allowable payload for the RH-TRU 72-B. This document is a catalog of RH-TRU 72-B authorized contents by site. A content code is defined by the following components: • A two-letter site abbreviation that designates the physical location of the generated/stored waste (e.g., ID for Idaho National Laboratory [INL]). The site-specific letter designations for each of the sites are provided in Table 1. • A three-digit code that designates the physical and chemical form of the waste (e.g., content code 317 denotes TRU Metal Waste). For RH-TRU waste to be transported in the RH-TRU 72-B, the first number of this three-digit code is “3.” The second and third numbers of the three-digit code describe the physical and chemical form of the waste. Table 2 provides a brief description of each generic code. Content codes are further defined as subcodes by an alpha trailer after the three-digit code to allow segregation of wastes that differ in one or more parameter(s). For example, the alpha trailers of the subcodes ID 322A and ID 322B may be used to differentiate between waste packaging configurations. As detailed in the RH-TRAMPAC, compliance with flammable gas limits may be demonstrated through the evaluation of compliance with either a decay heat limit or flammable gas generation rate (FGGR) limit per container specified in approved content codes. As applicable, if a container meets the watt*year criteria specified by the RH-TRAMPAC, the decay heat limits based on the dose-dependent G value may be used as specified in an approved content code. If a site implements the administrative controls outlined in the RH-TRAMPAC and Appendix 2.4 of the RH-TRU Payload Appendices, the decay heat or FGGR limits based on a 10-day shipping period (rather than the standard 60-day shipping period) may be used as specified in an approved content code.

Recent advances in computer technology, together with improved electronic access to medical knowledge, have heightened interest within the medical education community concerning the creation of multimedia systems that are capable of providing students with integrated presentations that incorporate problem-specific, high-resolution video, graphics, sound, sequences, simulations, and text. The substantial effort required to author multimedia knowledge management applications has revealed a need to develop tools that support the organization, indexing, and sharing of content both within and across institutions. As part of our ongoing work in knowledge management, we have developed MEDBase, a prototype tool for organizing and indexing multimedia content.

Content-based downloading for digital video  

NASA Astrophysics Data System (ADS)

In this paper we examine a content-based method to download/record digital video from networks to client stations and home VCR's. The method examined is an alternative to the conventional time-based method used for recording analogue video. Various approaches to probing the video content and to triggering the VCR operations are considered, including frame signature matching, program barcode matching, preloaded pattern searching, and annotation signal searching in a hypermedia environment. Preliminary performance studies are conducted to provide some insights into this approach.

Soil clay content underlies prion infection odds  

USGS Publications Warehouse

Environmental factors-especially soil properties-have been suggested as potentially important in the transmission of infectious prion diseases. Because binding to montmorillonite (an aluminosilicate clay mineral) or clay-enriched soils had been shown to enhance experimental prion transmissibility, we hypothesized that prion transmission among mule deer might also be enhanced in ranges with relatively high soil clay content. In this study, we report apparent influences of soil clay content on the odds of prion infection in free-ranging deer. Analysis of data from prion-infected deer herds in northern Colorado, USA, revealed that a 1% increase in the clay-sized particle content in soils within the approximate home range of an individual deer increased its odds of infection by up to 8.9%. Our findings suggest that soil clay content and related environmental properties deserve greater attention in assessing risks of prion disease outbreaks and prospects for their control in both natural and production settings. ?? 2011 Macmillan Publishers Limited.

[Acrylamide content in potato crisps in Poland].  

PubMed

The main source of acrylamide in the diet are thermally processed carbohydrate-rich products, mainly those obtained from potatoes. Acrylamide is a substance with neurotoxic, genotoxic and carcinogenic properties. The International Agency for Research on Cancer classified it as a potential human carcinogen in 1994. The purpose of this study was to assess acrylamide content in 24 samples of crisps randomly collected in Poland in 2004. Acrylamide was determined in the form of brominated derivatives by gas chromatography coupled with mass spectrometry. The average acrylamide content in the crisp samples examined was 998 mg/kg of the product, ranging from 352 to 3647 microg/kg, depending on the type of the crisps. The factor determining the differences in acrylamide content in the product was also the manufacturer. The average content of acrylamide in the crisps produced by three different manufacturers (manufacturers 1-3) was ca. 600-900 microg/kg, and in the crisps produced by manufacturer 4 was ca. 3 times higher. Moreover, substantial differences were found between the same types of crisps produced by the same manufacturers but originating from different manufacturing batches. The results obtained suggest the effects of various technological processes and raw material types on the level of acrylamide in crisps. PMID:17193744
