Inventory of Early Avionics Studies
Get PDFThese documents were sent to us from William E. Mallary of the Spacecraft Data Management Office (EH). They consist primarily of contractor reports from early avionics studies produced between 1968 and 1975. The documents constitute a run of three linear feet organized by contractor name and are arranged in chronological order
Inventory of Romere ALT Wind Tunnel Test Data
Get PDFThis subseries of documents was received from Paul Romere who worked in the Engineering Directorate's Navigation, Control & Aeronautics Division. The run consists predominantly of raw ALT wind tunnel test data. Since this is a preliminary inventory, materials have not been culled and have been kept in their original folders. Related documents can be found in the Space Shuttle Aerothermodynamic Data subseries. Particularly helpful will be RP1125, "Space Shuttle Wind Tunnel Testing Program Summary" located in box 0026B. This document discusses Ferry / ALT Configurations, test designations and document titles from the Dataman database wind tunnel test reports. Documents run from 1964 through 1985. Early documents include Apollo and early Shuttle configuration data
Inventory of STS-4 Mission Documents
Get PDFThese are documents related to STS-4 and arranged chronologically. They include press information, mission reports, and flight data
Oa1s and Oa2s Radiative corrections for w-boson production at the tevatron and atlas experiment
No full textIn this thesis, we propose an approach for calculating W-Boson Transverse
Momentum Dependent (TMD) distributions using the LHAPDF library with nCTEQ15, MSTW2008 and CT10 Parton Distribution Functions (PDF). We utilize ManeParse as a PDF reader in the Mathematica framework for importing and computing relevant cross-sections, luminosity functions, and error analysis, and additionally allow cross-check with a number of sum rules. A proper description of TMD distributions requires resummation of large logarithms responsible for the divergence of the perturbation series in the strong coupling as. Our proposed calculation is for next-to-leading-order (Oa1s) and next-to-next-to-leading-order (Oa2s) large logarithmic perturbative corrections for the differential W pT partonic cross-sections for processes of the form pp -> W + X. The goal of large logarithmic corrections with threshold resummation is to improve the accuracy of the pT distribution thus reducing dependence of the cross-section on renormalization (uR) and factorization (uF) scales, and plays a role in Higgs searches, precision measurement of the W-boson mass, as well as for testing perturbative QCD
Inventory of Communications Interface Equipment (CIE)
No full textThis subseries contains materials related to the development of the Communications Interface Equipment (CIE) unit, from 1981 to 1985. The primary function of the CIE was to provide a flexible, onboard two-way communication interface between attached and detached payloads, the orbiter communications and tracking and data subsystems and future Orbiter payload work station (OPWS) in terms of signal routing, format handling and command/telemetry handling. Its two basic functions were command (to direct operations) and telemetry (to monitor operations). The provenance of this collection is the Avionics Project Office (EH13) of the Avionics Division in the Engineering Directorate. The names of Steven Nance and Dave Tadlock appear on the majority of the documents. The collection needed only slight rearrangement for a chronological presentation. Two introductory folders on the functions and purpose of the CIE begin the subseries. The ensuing documents concern various aspects of the Preliminary Design Review (PDR) and the Critical Design Review (CDR). The collection ends with some documents relating to payloads and the OPWS
Inventory of Germany Files
No full textAs Technical Executive, Mr. Daniel M. Germany assisted Mr. Yardley, NASA Headquarters Associate Administrator for the Office of Space Transportation Systems, in solving difficulties involving the tiles on the Shuttle. This subseries consists primarily of information on these tiles which formed the Thermal Protection System (TPS) for the orbiter vehicle. The files are dated from 1979 to 1983, but the bulk of them fall between 1979 and 1980
Deriving the initial conditions of the electroweak and QCD phase transitions and testing a numerical relativity code.
Get PDFThe field of Numerical Relativity (NR) has been primarily driven by the study of largescale dynamics involving binary systems of black holes and neutron stars. Due to the nature of the underlying theory, NR also has the ability to simulate relativistic fluids. Being radiation dominated, the early universe can be modeled as a relativistic plasma, and the proper Stress-Energy tensor can be utilized with Einstein’s Field Equations to evolve the conditions of the Early Universe over time. These simulations can give us key insights pertaining to the development of the universe and the formation of large-scale systems. Magnetogenesis is of particular interest, as characterizing this phenomenon could shed light on the seeding and formation of galaxies. Addition-ally, these techniques can be used to derive gravitational-wave spectra from the events that took place during these time periods. This thesis aims to derive the conditions present in the early universe during the Electroweak (EW) and Quantum Chromodynamic (QCD) phase transitions. These conditions are prerequisites for SpecCosmo, a NR code being developed at the University of Houston-Clear Lake, which utilizes the techniques of NR to model the evolution of the early universe. This thesis will also investigate the ability of SpecCosmo to handle relativistic shocks in its current state. The shock capturing ability of the code will be gauged using a suite of tests from work by Komissarov [1, 2]. Once the shock capturing ability of SpecCosmo has been analyzed, SpecCosmo will be ready to accept the initial conditions calculated here that can then be used in simulations of the early universe to study its development and characteristics

Knowledge and clinical practice of therapists treating comorbid anxiety and insomnia
Get PDFThe purpose of this study was to explore the extent to which therapists who treat anxiety also treat comorbid insomnia. A survey was created to test therapists’ knowledge about insomnia and their expertise related to effective treatment methods. Results indicate that the majority of therapists in this study have not kept up with research that shows that anxiety and insomnia are bidirectionally causative, interactive, and exacerbating. They have not altered the way they treat clients to ensure that, when treating anxiety, issues related to insomnia are identified and specifically addressed. Additionally, they have failed to learn best practices for treating insomnia. Of the therapists in this study, 59% reported that they do not treat insomnia when it is comorbid with anxiety, and 82% do not use the most efficacious treatment for insomnia, Cognitive Behavioral Therapy for Insomnia (CBT-I), when their clients are experiencing it. A subgroup of therapists who treat insomnia with CBT-I showed superior performance on every measure of the test and on self-reported treatment outcomes. Further exploration of the results, recommendations for future research, and practical implications are discussed.
