“STARLIGHT SUITE”: A COMPOSITIONAL EXPLORATION OF THE ARGO NAVIS CONSTELLATIONS IN THREE MOVEMENTS
<p>This thesis explores a compositional technique in which stellar constellations are arranged upon musical staves in a variety of iterations to create a basis from which to draw melodic, harmonic, and rhythmic material. These raw extrapolations of unaltered notes are then arranged and orchestrated …

STARlight: A C++ Object-Oriented Monte Carlo Event Generator for Ultra-Peripheral Collisions
Ultra-peripheral collisions occur when nuclei pass one another without overlapping. The intense electric fields present can be treated as a flux of virtual photons; these photons can interact with the other nucleus or each other, producing a range of particles, including vector mesons and lepton …

Exclusive J/Ψ Vector-Meson production in high-energy nuclear collisions: a cross-section determinaton in the Colour Glass Condensate effective field theory and a feasibility study using the STARlight Monte Carlo event generator
… study using Monte Carlo simulations done by the STARlight event generator. A prediction is made for how many exclusive J /Ψ vector-mesons are expected to be detected by ATLAS in a data set corresponding to 160 μb−1 total integrated luminosity. It is found that the muon reconstruction efficiencies …

Simulation and testing of wavefront reconstruction algorithms for the deformable mirror (DeMi) cubesat
… Coronagraphs are typically used to block the starlight to achieve high contrast, but atmospheric, thermal, and mechanical aberrations can cause spurious speckles of starlight to contaminate the image. Use of space telescopes removes atmospheric aberrations, but other sources still remain. In …

Adaptive Wavefront Estimation Algorithms for High-Contrast Imaging of Exoplanets
… the exoplanet must be able to suppress the starlight to achieve a “contrast” of 10−10 in the image. This is typically achieved using a coronagraph, which blocks the light from the star while allowing the light from the planet to pass through. However, some starlight that leaks through the …

Monitoring of the Interstellar Dust Stream in the Inner Solar System Using Data of Different Spacecraft
… interstellar dust only through observations of starlight extinction and infrared emission. Therefore, the in-situ detection of interstellar dust, based on detectors carried by spacecraft, was a major step for dust astronomy. This method showed that one can learn a lot about the interstellar …

Photoproduction of ηc mesons in ultra-peripheral Pb+Pb collisions at √sNN= 5.02 TeV at the LHC
… performed using nine decay channels of the ηc. STARlight and PYTHIA8 Monte Carlo simulations were used to understand the detector acceptance for each channel. A total luminosity of 101.7 µb^-1 was analyzed for this study. All of the ηc decay channels containing only charged pions and kaons in …

ρ^' Photoproduction in ultra- peripheral heavy ion collisions with the ALICE detector
… The detector acceptance was estimated using the STARlight Monte Carlo simulations. The efficiency-corrected ρ' mass distribution was fit with both a single Breit-Wigner function, to compare with the results obtained by the STAR collaboration and with a combination of two Breit-Wigner functions, …

The relationship of school-wide positive behavior supports to male students' standardized test scores, office discipline referrals and suspensions in an urban middle school
… three cohorts of sixth grade boys enrolled at Starlight Middle School, a large, urban school in the Midwest. A comparison was made between pre-, partial, and full intervention data, during three consecutive years of implementation of School-wide Positive Behavior Supports (SWPBS) as a Tier 1, …

Revealing the Nature of Exoplanetary Atmospheres
… star, absorption features are imprinted into starlight passing through the planetary atmosphere. By analysing the resultant transmission spectrum, one can reveal the chemical composition of these distant worlds. Already, this technique has yielded detections of multiple chemical species in …

Ethical Relationality in Land-based Practices: Braiding Stories, Land, and Spirit
Abstract The purpose of this study is to find ways to sustain, validate and legitimize Tsuut’ina ninisha (way of life), and restore land-based practices that are critical for identity and survival within Tsuut’ina Nation schools. The research question guiding this study is: What is required to …

Maps and masses of transiting exoplanets : towards new insights into atmospheric and interior properties of planets
… solely from transmission spectra, i.e. the starlight filtered by a planet's atmosphere during transits. Determination of an exoplanet's mass is key to understanding its basic properties, including its potential for supporting life. To date, mass constraints for exoplanets are predominantly …

Embedded Computing for Wavefront Control on Future Space Telescopes
… telescopes will use adaptive optics to suppress starlight to directly image and characterize exoplanets. A measurement using this technique may be the first to detect extraterrestrial life in the universe. However, the real-time execution of adaptive optics control algorithms places unprecedented …
