description: Inferring shape, reflectance and illumination from an image enables us to better understand a scene and has opened up a wide range of socially-compelling applications ranging from virtual reality, entertainment and home surveillance. However, this is a particularly challenging problem since all the factors are combined into a single observation. At the same time, the ubiquity of mobile devices has raised immense opportunities for wide spread adoption of such techniques. Toward this end, this dissertation addresses the problem for the shape, reflectance and illumination estimation using sensors and illuminants commonly found on commodity devices, such as smart phones and tablets. We focus on two subsets of the problem. We first address the
problem of estimating the shape and reflectance of objects that exhibit spatially-varying reflectance under known single illuminant. Our contributions here are two-fold. First, we provide a non-iterative technique for per-pixel shape and reflectance, that is able to outperform the state-of-the-art methods on a wide range of real scenes. Second, we translate our technique to mobile devices and demonstrate capabilities in estimating as well as editing reflectance in spite of the ash unit and camera sensor being collocated.
Next, for a Lambertian scene being illuminated with
multiple light sources, we propose a method to separate and manipulate the scene illuminants based on their spectral differences. As before, we make two contributions. First, we derive physics based constraints for the ash/no-ash image pairs and provide identifiable analysis with respect to the number of light sources in the scene. We show that this separation can be used to support applications like white balancing, lighting editing, and RGB photometric
stereo, where we demonstrate results that outperform
state-of-the-art techniques on a wide range of images. Second, to address the limitations of the
ash light for the mobile devices, such as the presence of strong ambient light as well as the scenes
with large depth variations, we further demonstrate the ability
to separate the image by simulating the
ash image with a deep neutral network. We show that we are able to produce high quality outputs that match the performance of previous methods that required a ash/no-ash pair, while being more practical in requiring only a single image. We believe that, all together, the techniques developed in this dissertation makes a significant advance in our ability to not just estimate a scene's shape, reflectance, and illumination but also enable subsequent inference and post-processing capabilities.
How Different Are Different diff Algorithms in Git?

description: Automatic identification of the differences between two versions of a file is a common and basic task in several applications of mining code repositories. Git, a version control system, has a diff utility and users can select algorithms of diff from the default algorithm Myers to the advanced Histogram algorithm. From our systematic mapping, we identified three popular applications of diff in recent studies. On the impact on code churn metrics in 14 Java projects, we obtained different values in 1.7% to 8.2% commits based on the different diff algorithms. Regarding bug-introducing change identification, we found 6.0% and 13.3% in the identified bug-fix commits had different results of bug-introducing changes from 10 Java projects. For patch application, we found that the Histogram is more suitable than Myers for providing the changes of code, from our manual analysis. Thus, we strongly recommend using the Histogram algorithm when mining Git repositories to consider differences in source code.

description: The poems in this autobiographical collection explore the brokenness of family. I asked myself what does it mean to be a part of a family, to live in a family that is broken apart? I began this project with the belief that much of my material would take on the difficult task of writing about trauma that created fracture in my own family’s make-up. Marital separation, abuse, illness, death; these struggles seemed to be the cause of my family’s brokenness. Yet, what I found as I wrote was that trauma itself is not really responsible for the dysfunction in a family. It is in the aftermath of a crisis when individuals in a family must decide how to deal with the offending issues and interact with one another that will determine if the family will survive the breakage. My poems probe the individual relationships within my family under the strain of fracture.

title: Spurious divergences in Dyson-Schwinger equations
Creators: name: Huber, Markus Q.
name: Smekal, Lorenz von
Publisher: name: Springer Nature
Year: 2022

description: We revisit the treatment of spurious ultraviolet divergences in the equation ofmotion of the gluon propagator caused by a momentum cutoff and the resulting violation of gauge invariance. With present continuum studies of the gluon propagator from its DysonSchwinger equation reaching the level of quantitatively accurate descriptions, it becomes increasingly important to understand how to subtract these spurious divergences in an unambiguous way. Here we propose such a method. It is based entirely on the asymptotic perturbative behavior of the QCD Green’s functions without affecting non-perturbative aspects such as mass terms or the asymptotic infrared behavior. As a particular example, this allows us to assess the possible influence of the tadpole diagram beyond perturbation theory. Finally, we test this method numerically by solving the system of Dyson-Schwinger equations of the gluon and ghost propagators.
title: Intersections of Ideologies: Comparisons of the Ku Klux Klan, the Skinhead Movement, and White Mainstream America

subject: Masculinity

description: This thesis discusses the intersections of the dogma of the white supremacy movement and a particular subset of the mainstream United States. Specifically, it considers how the ideologies of the Ku Klux Klan and the Skinhead movement overlap with that of white, Christian America. The approach taken is anthropological; this thesis combines previously conducted studies of these far-right, pro-white groups with firsthand research of both the mainstream and white supremacist online media in order to more fully contextualize these groups in the culture in which they live. After analyzing the historical setting and context of these white supremacist groups in relation to white, Christian America, this thesis looks at several important and overarching themes. These include the dehumanization of the Black, female and “un-American” Other; the idea that whiteness is exclusively constructed to include only certain individuals; and masculinity as constructed in the same way: rather exclusively and violently. Additional themes include the management and shifting of guilt and blamelessness from the in-group, as well as the conceptualization of space as the control of more abstract constructs, such as religion and marriage. Through the combination of secondary and primary research, this thesis finds that the messages, mores, ideologies, and themes present in both the white supremacy movement and in the white mainstream come from the same fundamental place. It seeks to develop these connections as complex in nature. Historically, these connections have sometimes been much more overt; for instance, in some places, support for these groups or for racist ideology has been outwardly celebrated. However, the present connections between the Ku Klux Klan, the Skinhead movement, and white mainstream America are often more difficult to detect, though no less important. This thesis seeks to illuminate these connections, in the hopes of aiding those who seek to sever them completely.

description: Electron-hole pair excitations in the insulating cuprates $Sr_2CuO_2Cl_2$ were investigated by angle-resolved electron energy loss spectroscopy. The optically allowed and optically forbidden transitions were observed to be strongly anisotropic in $Cu-O_2$ plane. The former show a large energy dispersion $\sim 1.5$eV along [110], and the latter appear at a higher energy position ($\sim 4.5$eV) only along [100], but not along [110]. We interpret these results as transitions involving excitons. A small exciton model is examined to explain both the observed features.

description: Coronal Mass Ejections (CMEs) are believed to be effective in producing shocks in the solar corona and the interplanetary space. One of the important signatures of shocks and shock acceleration are Type II solar radio bursts that drift with the shock speed and produce bands of fundamental and higher harmonic plasma radio emission. An intriguing aspect of Type II radio bursts is the occasional split of a harmonic band into thinner lanes, known as band-splitting. Here, we report a detailed imaging and spectroscopic observation of a CME-driven shock producing band-splitting in a Type II burst. Using the Low Frequency Array (LOFAR), we examine the spatial and temporal relation of the Type II burst to the associated CME event, use source imaging to calculate the apparent coronal density, and demonstrate how source imaging can be used to estimate projection effects. We consider two widely accepted band-splitting models that make opposing predictions regarding the locations of the true emission sources with respect to the shock front. Our observations suggest that the locations of the upper and lower sub-band sources are spatially separated by $\sim 0.2 \pm 0.05 \, \mathrm{R_\odot}$. However, we quantitatively show, for the first time, that such separation is consistent with radio-wave scattering of plasma radio emission from a single region, implying that the split-band Type II sources could originate from nearly co-spatial locations. Considering the effects of scattering, the observations provide supporting evidence for the model that interprets the band-splitting as emission originating in the upstream and downstream regions of the shock front, two virtually co-spatial areas.

Ultra-High Energy Neutrino-Nucleon Cross Section and Radiative Corrections

description: A cubic kilometer scale experiment has been proposed to detect cosmic neutrinos of energy from tens of GeV up to the highest energies observed for cosmic rays, around 10**20 eV, or possibly even beyond. Detection efficiencies depend crucially on the neutrino-nucleon cross section at these energies at which radiative corrections beyond the lowest order approximation could become non-negligible. The differential cross sections can be modified by more than 50% in some regions of phase space. Estimates of corrections to the quantities most relevant for neutrino detection at these energies give, however, less dramatic effects: The average inelasticity in the outgoing lepton is increased from about 0.19 to 0.24. The inclusive cross section is reduced by roughly half a percent. The dominant uncertainty of the standard model ultra-high energy neutrino-nucleon cross section therefore still comes from uncertainties of the parton distributions in the nucleon at very low momentum fractions.

description: We demonstrate ultrasound detection with 500-$μ\mathrm{m}$-diameter photonic-crystal slab (PCS) sensors fabricated from CMOS-compatible technology. An ultrasound signal impinging a PCS sensor causes a local modulation of the refractive index (RI) of the medium (water) in which the PCS is immersed, resulting in a periodic spectral shift of the optical resonance of the PCS. The acoustic sensitivity is found to scale with the index sensitivity $S$ and quality factor $Q$. A noise equivalent pressure (NEP) of 650 Pa with averaging (7.4 Pa$/\sqrt{\mathrm{Hz}}$) and relative wavelength shifts of up to 4.3$\times10^{-5}$ MPa$^{-1}$ are measured. The frequency response of the sensors is observed to be flat from 1-20 MHz, with the range limited only by our measurement apparatus.

description: The poems that appear in this thesis project explore the intersections between death, the body, the soul, and the physical landscape. By conflating these subjects upon one another, the speaker often speculates the about what is natural and unnatural in the dying and decaying process. The world constructed during these ruminations consists almost entirely of metaphors—a place where one thing always refers to something else. Partially eckphrastic, these poems also look at the artistic works of Sally Mann, Tsurisaki Kiyotaka, 20th and 21st doctors, and our own environment. Careful consideration is given to the punctuation within each poem and the form of the poem on the page.
The Ubiquitous Imprint of Radiative Acceleration in the Mean Absorption Spectrum of Quasar Outflows

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: Observational evidence revealing the main mechanisms that accelerate quasar outflows has proven difficult to obtain, due to the complexity of the absorption features that this gas produces in the spectra of the emission sources. We build 36 composite outflow spectra, covering a large range of outflow and quasar parameters, by stacking broad ($>450\,{\rm km\,s^{-1}}$) absorption line systems in the spectra of SDSS-III/BOSS DR12 quasars. The two lines of the atomic doublet of CIV, with a separation of $\approx 497\,{\rm km\,s^{-1}}$, as well as those of other species appear well resolved in most of our composites. This agrees with broad outflow troughs consisting in the superposition of narrow absorbers. We also report on the ubiquitous detection of the radiative-acceleration signature known as line locking in all our composite outflow spectra, including one spectrum strictly built from broad absorption line (BAL) systems. This is the first line-locking detection in BAL composite spectra. Line locking is driven by the CIV atomic doublet, and is visible on the blue side of most strong absorption transitions. Similar effects from the doublets of OVI, SiIV, or NV, however, seem to not be present. Our results confirm that radiation pressure is a prevalent mechanism for accelerating outflows in quasars.

description: We have studied electromagnetic line emissions from near-horizon region in the extremal Kerr-Taub-NUT black hole spacetime and then probe the effects of NUT charge on the electromagnetic line emissions. Due to the presence of the NUT charge, the equatorial plane is no more a symmetry plane of the KTN spacetime, which leads to that the dependence of electromagnetic line emission on the NUT charge for the observer in the Southern Hemisphere differs from that in the Northern one. Our result indicate that the electromagnetic line emission in the Kerr-Taub-NUT black hole case is brighter than that in the case of Kerr black hole for the observer in the equatorial plane or in the Southern Hemisphere, but it becomes more faint as the observer's position deviates far from the equatorial plane in the Northern one. Moreover, we also probe effects of redshift factor on electromagnetic emission from near-horizon region in the extremal Kerr-Taub-NUT black hole spacetime.

description: In this paper, development history and result of a reliable performance gas generator of 75 tonf-class liquid rocket engine is described. Based on the experience acquired from the 30 tonf-class gas generator development, the almost identical concept was adopted to 75 tonf-class gas generator such as a coaxial swirl injector and a regeneratively cooled combustion chamber. During the entire development process using the full-scale and subscale technological demonstration model and development model up to now, combustion tests of over 430 times and cumulative time of over 17 700 seconds have been carried out for a 75 tonf-class gas generate. Now the 75 tonf-class fuel-rich gas generator shows very reliable and reproducible characteristics throughout the entire lifetime including the flight test which was done with the test launch vehicle in November 2018. Thus, it can be said that the development of a 75 tonf-class fuel rich gas generator which will be used in Korea first independent space launch vehicle, KSLV-II was finished successfully.

description: The production of charged Higgs boson pairs from gluon-gluon fusion is studied in the minimal supersymmetric model(MSSM) at proton-proton colliders. We find that the contribution of the scalar quark loops to the subprocess production rate is substantial and consequently the production rate in proton-proton colliders is enhanced in the MSSM if there exist scalar quarks with favorable masses. The results show that this cross section may reach a few femptobarn in the future LHC collider with plausible values of the parameters.

description: Numerical simulations of three-dimensional disturbances generated near a wall underexpanded jet in a Mach 5.4 flat-plate boundary layer are carried out. The Navier-Stokes equations for compressible perfect gas are integrated using the in-house solver implementing an implicit finite-volume shock-capturing scheme with the second-order approximation in space and time. The wall normal injection through a circular hole forms an underexpanded jet of barrel shape resembling an isolated roughness element. The jet induces a system of vortices propagating downstream. The vortices are destabilized at a short distance leading to rapid nonlinear breakdown and formation of a \"young\" turbulent wedge. The vortex structure, its instability and breakdown to turbulence resemble those induced by an isolated roughness element. The disturbances evolution is analyzed through Q-criterion visualizations, wall pressure spectra, and skin friction coefficients. Results show that the normal wall injection effectively trips the boundary layer.

MODEL-BASED APPROACH

description: A CDF is an advance design installation, equipped with a network of computers, multimedia devices and software all interconnected to each other. It allows to implement the Concurrent Design (CD) to the project development; specifically for the space missions. This methodology consist of a design style based on the continuous flow of information, previously defined as design parameters, among all the space subsystems. This information is exchanged between all users using a database, so information is continuously updated. The configuration of a satellite refers to the location of the different equipments, hardware and components in the primary structure. The definition of the configuration should be developed at the same time as the rest of the subsystems are defined. However, commonly in designs that are made in a CDF, the configuration used to be shifted until the satellite design has been fully defined. This causes that at the final stages of development, especially for small satellites, problems about the positioning and the available free space arise. Discovering that a certain component does not fit inside the satellite or that there is not enough external surface for some equipment are typical errors that appear if a correct design of the configuration has not been made. This module allows creating a simplified CAD model of the satellite with all the necessary equipment to define the configuration in a very simple way. Based on Microsoft Excel(R) and connected with Dassault CATIA(R), the module automatically create a dummy model of all the components, with the proper properties (volume and mass). It provides the user a complete equipment list and the values of the centre of gravity (C.o.G.), as well as the inertia matrix, once the configuration have been defined.
title: Failed States or Failed Solutions? An Empirical Assessment of U.S. Treatment of State Failure in the Developing World

description: Since the end of the Cold War, the effects of state failure have plagued the international community. There are many purported solutions to state failure like financial assistance and multi-national interventions, though the success of these solutions is difficult to measure. Additionally, the empirical likelihood that the West will indeed respond to state failure is missing from state failure discourse in both the academic and policy realms. Crucially, if the West does not actually respond predictably to state failure – or at least in the ways that we should expect – then the effort devoted to finding the solution to state failure may be in danger. This project seeks to fill this critical gap in the literature by conducting one of the first mixed-methods studies of its kind. Using an original large-n dataset, I test the strength of state failure in determining the likelihood of an intervention (financial or military) by the United States. I find that state failure itself is not a good indicator of where the U.S. will respond. Secondly, I conduct a case study of Liberia and Nigeria – two failed states that have received different treatment by the United States. I find that the important factors in determining intervention in these cases include pressure from the international community, the perceived threat of terrorism, and the failed states’ strategic position as a regional player. This study adds to a growing body of literature that is critical of the usage of the term ‘failed state,’ and also adds a flavor to the debate about whether or not the international community has a substantive effect on U.S. foreign policy. The critical empirical relationship between state failure and U.S. response may help to determine the actual success (or failure) of international responses to state failure, and can help to inform and drive efforts in the study for new solutions.

description: We show how to find higher generating families of subgroups, in the sense of Abels and Holz, for groups acting on Cohen-Macaulay complexes. We apply this to groups with a BN-pair to prove higher generation by parabolic and Levi-subgroups and describe higher generating families of parabolic subgroups in Aut(F_n).

description: Despite significant physical, emotional, and cognitive benefits, outdoor and environmental education (OEE) is not regularly implemented within a K-12 setting. Yet there are some teachers across the United States who have embraced OEE in a thoughtful and innovative way, successfully overcoming noteworthy barriers. The goal of this study was to understand the experiences of these teachers in order to advance the field of OEE. Using a phenomenological approach, I interviewed twelve educators who regularly implement OEE within the context of a typical school day. I analyzed over sixteen hours of interview transcripts as well as participant-submitted photographs. Four main themes (threads) emerged from the phenomenological data, shedding light on how K-12 teachers experience OEE: (1) a navigation of shared agency, (2) a harmony between freedom and structure, (3) a contextualization of integrated learning, and (4) a collective joy and wonder. The detailed participant narratives that highlight these themes will resonate with school districts, administrators, and preservice teaching programs moving towards OEE implementation. The findings from this study add to the preexisting understanding of OEE’s complexities, offering stories, imagination, and a pathway into understanding the lived experiences of educators who teach in, for, and about the outdoors. The phenomenological insights within this dissertation can lead towards OEE as a more prevalent approach to K-12 learning.

description: Normal function of the placenta depends on the earliest developmental stages when trophoblast cells differentiate and invade into the endometrium to establish the definitive maternal-fetal interface. Previously, we identified the ubiquitously expressed tumour suppressor BRCA1-associated protein 1 (BAP1) as a central factor of a novel molecular node controlling early mouse placentation. However, functional insights into how BAP1 regulates trophoblast biology are still missing. Using CRISPR/Cas9 knockout and overexpression technology in mouse trophoblast stem cells, here we demonstrate that the downregulation of BAP1 protein is essential to trigger epithelial-mesenchymal transition (EMT) during trophoblast differentiation associated with a gain of invasiveness. Moreover, we show that the function of BAP1 in suppressing EMT progression is dependent on the binding of BAP1 to additional sex comb-like (ASXL1/2) proteins to form the polycomb repressive deubiquitinase (PR-DUB) complex. Finally, both endogenous expression patterns and BAP1 overexpression experiments in human trophoblast stem cells suggest that the molecular function of BAP1 in regulating trophoblast differentiation and EMT progression is conserved in mice and humans. Our results reveal that the physiological modulation of BAP1 determines the invasive properties of the trophoblast, delineating a new role of the BAP1 PR-DUB complex in regulating early placentation.

description: In the context of the design of partially reusable launch vehicles, different alternatives may be investigated to recover the first stage while minimizing the costs of reusability and maximizing the performance and reliability. In this paper, a winged configuration of reusable first stage, called glide-back, is studied. This architecture uses the main propulsion system of the first stage to perform a boost-back burn and return to the landing site by a gliding mode using additional lifting surfaces. A focus is made on the design of a reusability kit that can be added to a classical stage to provide it with reusability capabilities. The tradeoff between the design of the reusability kit and its impact on the ascent phase, staging point and global performance of the vehicle is investigated through aerodynamics and trajectory analyses.

description: The combustion of aluminum particles is a key factor for solid-propellant propulsion in terms of performance and stability. An automatic detection of droplets in Al-PLIF image was developed. The \"Maximally Stable Extremal Regions\" detection method is evaluated on two image sets previously obtained at 1.0 and 1.5 MPa. The method shows good detection performances compared to a set of Ground Truth images for both pressure levels. When applied to 3000-image series, more than 35000 objects were detected on LIF images. This is very promising for future statistical analysis of Al combustion based on Al-PLIF diagnostic.

description: The qualification of new technologies and new materials in the space sector is always subjected to a high number of qualification tests and maturity steps to go thru. Additive manufacturing technology opens a new opportunity to create new products with better performances than the ones limited to traditional manufacturing technologies, but at the same time the level of risk of implementation is higher due to the lack of maturity of the technology. To push the use of additive manufacturing technology it is needed to work on these identified risks and mitigate them step by step in the different phases: from requirements identification to material qualification, AM definition of the part and justification, inspection and validation by test. The opportunities that give us this technology is linked to the topology optimized new parts, looking for mass saving opportunity larger than 40%. Additive Manufacturing (and particularly Powder Bed Laser Fusion) is the technology able to manufacture the geometry output of the optimization process. Additionally, this novel design approach gives the opportunity of reducing the number of parts comparing with the traditional design, and keeping the same functionality. The aim of this paper is to describe how these steps are covered in two different applications. This use cases are CHEOPS AM Solar Array Brackets in Titanium and Scalmalloy and Umbilical connector bracket in Scalmalloy.
