Investigation of instrumentation and techniques for Army weather observation. Report no. 1-4, Feb. 1962-Mar. 1963 by Fred W Decker( Book )

5 editions published between 1961 and 1963 in English and held by 4 WorldCat member libraries worldwide

A description is given of observations and analysis of nine case studies of data obtained from a detailed mesometeorological surface observing system coincident with the collection of PPI and RHI data from an AN/CPS-9 weather radar and a vertically-pointing radar. The surface observations included measurements of the dropsize distributions, occasionally hail samples, charge on precipitation, and earth-air current in addition to the usual observations. Primary emphasis in this sudy centers on the orographic effects on the precipitation distribution. Use of stepped receiver gain permitted detailed analysis of radar data to reveal orographic effects and other factors operating in the precipitation process. (Author)

Single crystals of KC1 containing sulfate ions have exhibited a large number of IR absorption peaks unless the crystals also contained an excess of divalent cations, in which case the spectra consist chiefly of 3 prominent absorban ces. This paper reports observations on crystals where the divalent cation concentration was low enough so the spectra were complicated. Progress was made in accounting for the peaks observed. A crystal-to-melt distribution ratio for sulfate ions is reported which makes it convenient to estimate the sulfate concentration for a crystal grown from a melt of known composition. Since sulfate ions bear a double charge, one expects their incorporation in an alkali halide crystal to be accompanied by the formation of negative ion vacancies. If such is the case, some pro nounced effects upon the behavior of F centers may result. Experiments with crystals contain ing sulfate ions which were additively colored. The sulfate ions were reduced to other divalent anions (e.g. peroxide) by the coloration process; these anions then markedly affect the bleaching of F centers. (Author)
Effects of Pressure on Membrane-Associated Receptors and Effector Elements( Book )

2 editions published between 1989 and 1991 in English and held by 1 WorldCat member library worldwide

To investigate the effects of moderate hydrostatic pressures on signal transduction we have used the A (1) adenosine receptor inhibitory G protein (Gi) - adenylyl cyclase system in two species of sorpaenid fish which have served as a model for the study of pressure adaptation. These species, Sebastolobus alascanus and S. Altivelis, have similar body temperatures, but dwell at different depths, and thus experience different hydrostatic pressures. The experiments were designed to identify and define at the molecular level the effects of pressure on the components of the signal transduction system in isolation and on the entire functional complex. We have completed work characterizing the effects of pressure on the coupling efficiency of the A (1) adenosine receptor in brain membrane preparations. For the teleost brain membrane preparations, incubation at 5 C and 476 atm does not result in loss of adenylyl cyclase activity or coupling to the A (1) adenosine receptor on subsequent assays at atmospheric pressure. In contrast, rat brain membrane preparations lost 59% of their activity under these conditions
Leadership Development Institute for Vocational and Technical Education Personnel in the Western States. Final Report by Mildred, Ed Matthews( Book )

1 edition published in 1969 in English and held by 1 WorldCat member library worldwide

With greater emphasis being placed on vocational and technical education, there is an increasing demand for people to fill leadership roles at the local, state, and national levels of supervision. This demand prompted the establishment of an 8-day leadership institute for 20 western states. Nationally recognized experts participated in the institute and actively involved the 34 participants. The participants were provided with up-to-date information in vocational and technical education and were asked to prepare a plan of action that could be implemented upon their return home. Evaluation of the conference was done on a continuous basis by the participants as well as by an outside group. The institute was rated highly successful on the basis of evaluations, the followup of the participants, and feedback. This final report includes methods and procedures used by the institute and supplementary and appendix material. (Js)
Theoretical and field studies of seismic waves( Book )

1 edition published in 1964 in English and held by 1 WorldCat member library worldwide

The objective of the research was to determine a method for evaluating the size of a seismic source using amplitudes and/or energy content of the seismic waves generated by the source. Each distance range (local, near-regional, regional, and teleseismic) was considered separately to divide the major problem into several smaller ones. Only the initial seismic disturbance was considered for this work. Data recorded from Gnome, Hardhat, Haymaker, and Shoal nuclear explosions were chosen to represent the seismic sources for this work. The research that was done for seismic waves recorded in the various distance ranges will be discussed. In general, the continuity of energy of the seismic waves recorded from the above explosions was sought for the entire range of distances over which the seismic waves were recorded
Hybrid Computational Models for Skill Acquisition( Book )

2 editions published in 1998 in English and held by 1 WorldCat member library worldwide

The goal of this research was to develop a hybrid real time problem solving architecture that couples symbolic planning methods with connectionist reinforcement learning methods. The advantage of this hybrid architecture is that it can immediately achieve reasonable performance, because the symbolic planning system can quickly develop an acceptable control policy, but it can also gradually achieve optimal real time performance, because the reinforcement learning system will eventually converge on a near optimal policy. Many DoD problems would benefit from the ability to perform near optimal real time control of complex systems
Buoyancy-Driven Coastal Currents( Book )

2 editions published in 1998 in English and held by 1 WorldCat member library worldwide

The stability of a coastal upwelling jet and front was investigated using the primitive equations applied to a continuously stratified flow in geostrophic balance. A linear stability analysis explained the growth of two modes of instability with distinctly different horizontal scales. A long-wavelength mode was a modified version of a traditional baroclinic instability. A second, rapidly growing frontal instability was also found. The linear stability analysis was also applied to observed sections of salinity and velocity from the buoyancy-driven Alaska Coastal Current and, again, two modes of mesoscale variability were found. A three-dimensional, time-dependent, fine resolution numerical ocean circulation model was used to study the evolution of the unstable buoyancy-driven coastal jet. Early in the simulation, short-wavelength frontal instabilities grew and propagated along the jet. Eventually, the frontal instabilities were frictionally damped and the long-wavelength baroclinic instability became dominant. The baroclinic instability amplified into a series of backward-breaking waves whose crests eventually pinched off to form fresh, anti-cyclones while saline cyclones remained in the troughs. The scales of these eddies were consistent with those evident in maps of dynamic height from the Alaska Coastal Current
New Left Ideology: A Cross National Study by Knud S Larsen( Book )

1 edition published in 1971 in English and held by 1 WorldCat member library worldwide

This study was undertaken to broaden the scope of the components of the "New Left" Scale, first developed by Christie et al. At Columbia College (1969), by including students from a U.S. university not known for its activism and responses given by a sample of Japanese college students. In short, U. S. and Japanese students both agreed most that participatory democracy should be the basis of a new society and disagreed most that educational institutions should espouse political doctrines. Also, Japanese students combine trust in "most people" with distrust of government and political opposition, reflecting perhaps the greater political activism of the group; whereas, U. S. students agreed more with statements which indicated a liberal or even non-political trust. Finally, Japanese students agreed that extensive reforms perpetuate social evils and that militant confrontation is required, whereas the U. S. sample put great faith in legal social authority as a vehicle for change. In both countries, different factors are apparent suggesting that New Left ideology may be nation specific, I.E. take on different forms depending on national tradition. (Author/TA)
Multi-sensor Remote Sensing in the Nearshore( Book )

2 editions published between 2008 and 2009 in English and held by 1 WorldCat member library worldwide

The proposed program directly supports the Navy goal of predicting the 4D nearshore environment for amphibious operations that involve surf zone breaching. Our effort specifically involves improving our understanding of the fundamental relationships between nearshore hydrodynamic processes and remote sensing observations of these processes from multiple remote sensors. We utilize this understanding to improve our ability to numerically simulate and, hence, predict the time and space variability of the nearshore environment. The Navy also makes considerable use of remote sensing techniques for littoral mine and obstacle detection, and breaking-induced foam and whitewater can be a significant source of signal clutter for relevant sensing systems. In this regard, the proposed work will also explore the presence of foam and whitewater bubbles as revealed by optical and microwave systems, with the potential to aid in the design and tactical deployment of aerial reconnaissance imaging systems
Variability and Chaos: Neurointegrative Principles in Self-Organization of Motor Patterns( Book )

1 edition published in 1989 in English and held by 1 WorldCat member library worldwide

We discuss the possibility that variability may be a central feature of self-organizing processes. We suggest that variability may be inherently part of the mechanisms by which adaptive neurocircuits emerge, and contrast such functional neurocircuits against definitions involving anatomical or dynamical structures which the self-organizational definition both contains and supercedes. The experimental work focuses on an invertebrate animal, the sea slug, Pleurobranchaea californica, which has a rich behavioral repertoire of buccal/oral behaviors, and a relatively simple nervous system containing identifiable neurons. We present evidence from work on a set of 20 neurons, which we refer to as BCNs (buccal-cerebral neurons), that communicate between the buccal ganglion and cerebral ganglion. These neurons are crucial for generating all buccal/oral behaviors, and provide an advantageous source of experimental material for inquiring into the self-organization of group activity. Variability in the activity of the BCNs, and in the motoneurons that they drive, is attributable to low-dimensional chaos. These findings indicate that some variability may arise from the same mechanisms that generate the patterned activity: i.e., that the observed variations are not noise that is superimposed on the code underlying a behavior. The role of sensory feedback in the production of adaptive behavior of animals as they interact with complex and often unpredictable environments is discussed and we suggest that chaotic neural activity provides a means for the nervous system to create new informational space rendering animals more stably adaptable in such changing environments
Instrumentation for the Center for Cellular Mechanics( Book )

2 editions published in 1999 in English and held by 1 WorldCat member library worldwide

An integrated workstation for studying cellular mechanics has been installed for the purpose of educating students and conducting research on how information is mechanically processed in living cells. The integrated workstation consists of manipulator tools that can be used to probe living cells with mechanical force while they are in the view of a microscope. The instrumentation is expected to enhance ONR funded research on cell-based biosensors by helping to establish a scientific basis for observations that have been made of pronounced toxicological perturbations of the mechanical transport of information in cells. The instrumentation will also serve as a focal point for improving the capabilities of scientists and engineers at Oregon State University to conduct defense-oriented microdevice research that is inspired by the very small machinery of living cells
Matter-Wave Interferometry with Laser Cooled Atoms( Book )

2 editions published between 1991 and 1994 in English and held by 1 WorldCat member library worldwide

This program is investigating matter wave interferometry with laser cooled atoms. A slow beam of laser cooled rubidium atoms will be used as the matter wave source. The atom optical elements will be microfabricated amplitude transmission gratings which will be used in a three-grating interferometer to split and recombine the rubidium beam. The interferometer will be a useful new tool for precision atomic physics and a sensitive inertial sensor

Toward Optically Monitored Cytosensors( Book )

2 editions published between 1999 and 2004 in English and held by 1 WorldCat member library worldwide

A video microscopy system was set up to study optical changes in living biosensor cells in response to bioactive and neuroactive agents. The set of agents tested included both chemically defined toxic substances and regulators of cell activity, and undefined agents produced by microbes and by neuronal cells. It was clear that numerous agents can be detected by the changes they cause in the optical appearance of biosensor cells. These results help to provide the basis for future development of cell-based biosensors
3-D Wave-Structure Interaction with Coastal Sediments - A Multi-Physics/Multi-Solution-Techniques Approach( )

1 edition published in 2008 in English and held by 0 WorldCat member libraries worldwide

The long term goal of this research is twofold: (1) develop an advanced multi-physics model with a multi-numerical solution techniques approach to predict nonlinear dynamic behavior of impact burial and flow-induced motion of flexible structures (mines) and surrounding sediments (sand) in the marine environment; and (2) calibrate resulting models with experimental and field measurements. The predictive capability developed in this research will eventually be integrated into an overarching computational framework for the analysis and simulation of the dynamic behavior of naval systems in the marine environment of arbitrary water depth
Low-cost deposition methods for transparent thin-film transistors by Benjamin J Norris( )

1 edition published in 2003 in English and held by 0 WorldCat member libraries worldwide

The objective of this dissertation is to introduce low-cost processing methods for the fabrication of ZnO transparent thin-film transistors (TTFTs). A novel method for depositing ZnO body layers via spin-coating of a zinc nitrate-based spin solution is presented. The processing conditions of spin-coated ZnO are optimized to produce continuous and polycrystalline thin-films. Optimal spin-coated ZnO thin-films are obtained for a 32 nm thick film which is converted to ZnO at 600°C in air. Spin-coated ZnO TTFT mobilities are consistently in the range of 0.1--0.2 cm 2/Vs. Spin-coating deposition methods for HfO2 are presented as a novel way to deposit low-cost gate insulators. Spin-coated HfO2 dielectric has a breakdown field, dielectric constant, loss tangent, and leakage current at 1 MV/ cm of & sim;2.1 MV/cm, 12.1--13.5, 0.411%, and 17.37 nA/cm2, respectively. Additionally, ZnO TTFTs constructed using spin-coated HfO 2 gate insulators possess electrical characteristics similar to those obtained with aluminum oxide and titanium oxide superlattice (ATO) gate dielectrics
Spatial Variations of the Wave, Stress and Wind Fields in the Shoaling Zone( )

2 editions published between 2001 and 2003 in English and held by 0 WorldCat member libraries worldwide

Aircraft data collected at approximately 15 m above the sea surface in the coastal zone are analyzed to examine the spatial distribution of surface stress. Advection of stronger turbulence from land dominates the near-surface turbulence for the first few kilometers offshore. With offshore flow of warm air over cold water, strong stratification leads to very small surface stress. Because the stability restricts the momentum transfer to the waves, the aerodynamic surface roughness decreases to very small values, which in turn decreases atmospheric mixing. The redevelopment of the boundary layer farther downstream is examined. Computation of fluxes from observations for stable cases is difficult due to a variety of errors including large random flux errors, possible instrumental loss of small-scale flux, difference between the surface flux and that at the observational level, and inadvertent capture of mesoscale motions in the computed turbulent fluctuations. Although the errors appear to be substantial, the aircraft momentum fluxes compare favorably with those from sonic anemometers on two buoys and a tower at the end of a 570-m pier, even with near collapse of the turbulence
