A Real-Time Solution Strategy For Estimation Of Aerothermal Heating For Reentry Vehicles, Bhuvaneswari Rajendra Dec 2017

A Real-Time Solution Strategy For Estimation Of Aerothermal Heating For Reentry Vehicles, Bhuvaneswari Rajendra

Theses and Dissertations

Direct measurement of flight environment on a heat shield of a Reusable Launch Vehicle (RLV) is critical due to the extremely aerothermal heating experiences during the reentry phase. An alternative approach is to install thermocouple several millimeters below the heat shield surface to measure the heat shield temperature response and solve the associated inverse heat conduction problem (IHCP) in order to reconstruct the surface heat flux using the measured temperature response. The material properties and thicknesses of the Thermal protection system (TPS) make the reconstruction process more challenging when the thermocouples are placed far away from the surface. The focus …

Development Of Large-Area Gem Detectors For The Forward Muon Endcap Upgrade Of The Cms Experiment And Search For Sm Higgs Boson Decay In The H → Τ+Τ− → Μ+Μ−¯Νμνμ¯Ντντ Channel At √ S = 13 Tev, Vallary Shashikant Bhopatkar Dec 2017

Development Of Large-Area Gem Detectors For The Forward Muon Endcap Upgrade Of The Cms Experiment And Search For Sm Higgs Boson Decay In The H → Τ+Τ− → Μ+Μ−¯Νμνμ¯Ντντ Channel At √ S = 13 Tev, Vallary Shashikant Bhopatkar

Theses and Dissertations

Gas Electron Multiplier (GEM) technology is being considered for the forward muon upgrade of the Compact Muon Solenoid (CMS) experiment in Phase II of the CERN LHC. The first GEM Endcap (GE1/1) is going to be installed in the 1.5 <| η |< 2.2 region of the muon endcap mainly to control muon level-1 trigger rates after the second long LHC shutdown. A GE1/1 triple-GEM detector is read out by 3,072 radial strips with 453 µrad pitch arranged in eight η-sectors. A meter-long GE1/1 prototype-III was assembled at Florida Tech and tested in 20-120 GeV hadron beams at Fermilab using Ar/CO2 70:30 and the RD51 Scalable Readout System (SRS). Four GEM detectors with 2-D readout and an average measured azimuthal resolution of 36µrad provided precise reference tracks. Construction of this GE1/1 prototype-III detector and its performance in the test beam are described. Strip cluster parameters, detection efficiency, and spatial resolution are studied with position and high voltage scans. The plateau detection efficiency is [97.80 ± 0.2 (stat)]%. The azimuthal resolution is found to be [123.5 ± 1.6 (stat)] µrad when operating in the center of the efficiency plateau and using full pulse height information. The CMS upgrade design calls for readout electronics with binary hit output. When strip clusters are formed correspondingly without charge-weighting and with fixed hit thresholds, a position resolution of [136.8 ± 2.5 stat] µrad is measured, consistent with the expected resolution from strip-pitch/√ 12 = 131.3 µrad. The eight η-sectors of the detector show a similar response and performance. VFAT3 electronics are being considered for the readout system of GE1/1 detectors. The charge that is induced on the GE1/1 readout strips by minimum-ionizing particles is an important parameter that informs the design of the amplifier-shaper input stage of the VFAT3 chip. To estimate the input charge range for these electronics, the most probable value, mean value, and 99th percentile value of the Landau distribution of the charge induced on a single strip are measured and found to be 4 fC, 11 fC, and 115 fC, respectively. The Z/γ∗ → τ τ cross section in proton-proton collisions at √ s = 13 TeV is measured, using data recorded by the CMS experiment at the LHC during 2015 and corresponding to an integrated luminosity of 2.3 fb−1 . The product of the cross section and branching fraction is measured in the dimuon final state to be 1967 ± 121 (stat.) ± 92 (syst.) ± 37 (lumi.) pb, in agreement with the standard model expectation, computed at next-to-next-to-leading order accuracy in perturbative quantum chromodynamics. A search for Standard Model (SM) Higgs bosons decaying into pairs of tau leptons and then to two muons plus (anti)-neutrinos is performed using the data collected by the CMS detector in 2016 with 35.9 fb−1 of integrated luminosity. The upper limits on the cross section relative to SM prediction are calculated in three event categories with different jet multiplicities focusing on Higgs boson signal events produced via gluon-gluon fusion and vector boson fusion. A multivariate analysis with Boosted Decision Trees (BDT) is used to suppress the large Drell-Yan background. The di-tau mass is reconstructed using a Secondary-Vertex fit (SVFit) algorithm using a maximum likelihood approach. Experimental limits are presented in all three categories extracted from the maximum likelihood fit of reconstructed di-tau mass and the visible mass of the dimuon system. The signal strength for the combination of all three categories is estimated as -1.0 ± 1.7. The expected and observed upper limits with 95% CL is at 3.2 and 2.7, respectively, with respect to the SM cross section times branching fraction.

Metastable-State Nh Photoacids And Organic Photo Carbon Monoxide Releasing Materials, Aluthwatte Rallage Nawodi Madhusanka Abeyrathna

Theses and Dissertations

The recently discovered metastable-state photoacids (mPAHs) can produce a large proton concentration with high efficiency and good reversibility upon irradiation with visible light with moderate intensity. Therefore, mPAHs can be conveniently incorporated in to different systems to control various proton-transfer processes. Recently, several applications of mPAHs have been demonstrated. However, none of the previously reported mPAHs can function at a pH 7.4. Thus, biological applications of mPAHs are limited. In this work, mPAHs that can reversibly release a proton in PBS buffer (pH = 7.4) under visible light are designed and synthesized. NH-PAH-1 is the first of this type of …

Predatory Capacity Of King Crabs In Antarctica, Brittan V. Steffel Dec 2017

Predatory Capacity Of King Crabs In Antarctica, Brittan V. Steffel

Theses and Dissertations

For millions of years, cold water temperatures have excluded shell-crushing (durophagous) predators from continental-shelf environments off the western Antarctic Peninsula. Recently, however, king crabs, Paralomis birsteini, have been found in dense, reproductively viable populations on the upper continental slope, and rapid warming might enable them to expand to the shelf. King crabs are crushing shelled invertebrates on the slope, but calcification of sturdy, shell-crushing chelae is likely inhibited by the low saturation state of high-Mg calcite in the deep Southern Ocean. The objectives of this study were to better understand the predatory capacity of P. birsteini by estimating the potential …

Testing The Wind-Shock Paradigm For B-Type Star X-Ray Production With Θ Carinae, Trisha F. Doyle Dec 2017

Testing The Wind-Shock Paradigm For B-Type Star X-Ray Production With Θ Carinae, Trisha F. Doyle

Theses and Dissertations

We present Chandra X-ray grating spectroscopy of the B0.2V star, θ Carinae. θ Car is in a critical transition region between the latest O-type and earliest B-type stars, where some of these stars are observed to have UV-determined mass-loss rates much lower than theoretically expected. In general, X-ray emission in this low-luminosity regime should be less prominent than in O-star winds, but observations have shown a higher than expected production of X-ray emission from the winds of these stars (e.g., Cohen et al. 2008; Huenemoerder et al. 2012). A hot wind could explain weak UV wind signatures, but this severely …
