Efficient numerical methods for solving the Boltzmann equation for low-speed flows
… of the Boltzmann equation is performed using a quasi-random Monte Carlo integration approach for faster convergence. In addition, interpolation is used to reduce the effect of discretization errors. We find that cubic interpolation leads to accurate solutions which exhibit excellent conservation …

Gender Bias in Microlending: Do Opposites Attract?
<p>This study exploits a quasi-random assignment of clients to loan officers using a unique database and survey from a large microfinance bank in Nigeria to show that opposite-sex preferences affect credit demand and supply. We find that clients matched to loan officers of the opposite gender are …

Using Conflict and Support Counts for Variable and Value Ordering in CSPs
… using the renowned benchmarks which include random, quasi-random, pattern and real world instances. The test results show that the proposed variable ordering heuristic perform well in the cases of hard random and quasi-random instances. The test results also show that combining the proposed …

Essays on Institution and Innovation
… system of internet censorship. Leveraging the quasi-random timing of foreign app blockages, I find that Chinese substitute apps experienced a 30% increase in user base following foreign app bans. Using novel data extracted from compiled app code, I show that in-house technological development …

Resonances and Mixing in Confined Time-dependent Stokes Flows: The experiments, Numerics, and Analytics
… Second, chaotic advection and mixing due to quasi-random jumps of the adiabatic invariant (AI) occurring when a streamline crosses the separatrix surfaces is studied. Analytical expressions for the change in the AI near the separatrix surfaces are derived and compared with numerical …

Essays in Political Economy
… how and why the partisan composition of quasi-random panels of judges on the U.S. Federal Courts of Appeals affects consensus-building. I describe each chapter in more detail below. The first chapter, ``Persuasion with Ambiguous Receiver Preferences,'' describes a Bayesian persuasion …

Essays on the Economics of Labor and Criminal Justice
… Through a causal framework leveraging the quasi-random assignment of review prosecutors to cases in a Californian County, I assess how these severe filing decisions impact defendants differently by age, race, and gender. We find that a more severe filing decision increases recidivism …

Phase Stability In Cobalt-Based L12 Quaternary Intermetallics From Density Functional Theory
… studied via first-principles. A 32 atom special-quasi-random structure was used to mimic the experimentally observed solid solution sublattice. Density of states distributions were generated in order to directly observe the impact of alloying additions on the position of the pseudogap and number …

Mechanical properties of bio-absorbable materials
… continuous fiber plies, and multi-directional, random and quasi-random short-fiber composites were considered in our study. NDSANDS a concentric cylinder model computer software, was used to evaluate the stiffness and strength of the bioabsorbable composites with unidirectional fiber …

Multi-scale modelling of III-nitrides: from dislocations to the electronic structure
… structure (ELNES) data, (v) to apply the special quasi-random structures method to ternary III-nitride wurtzite alloys aiming to develop a methodology for modelling wurtzite alloys and to get quantitative agreement with experimental N K-edge ELNES structures, and (vi) to theoretically study strain …

Essays in Local Governance: Studies of Policy Choices, Resource Management, and Community Impacts
… In order to address that problem, I exploit quasi-random variation in land use controls resulting from Los Angeles Transit Oriented Communities (TOC) Affordable Housing Incentive Program. Using a spatial regression discontinuity design (RDD), I identify the effects of these land use …

Fast Multilevel Algorithms for the Electromagnetic Analysis of Quasi-Planar Structures
… of electromagnetic scattering and radiation from quasi-planar structures is a topic of great current interest, owing to the wide range of applications. A host of structures and surfaces are included in the quasi-planar class, including rough surfaces, quantum well infrared photodetector gratings, …

Employee Departure from Organizations: Three Empirical Essays
… attorneys. I find strong evidence that these quasi-random failures (which are likely to be weakly related to the broader economic environment) cause attorneys in rival firms to create startups, while other types of rival failures depress entry rates, probably because they proxy for weakness in …

Nonlinear Dynamical Analysis Of Microvascular Red Blood Cell Flow
… to another. Does this variability result from random or deterministic processes?;It was hypothesized that the dynamics observed result from non-linear dynamic processes. A variety of factors influence the passage of RBCs in capillaries and flow fluctuations may result from complicated feedback …

Audio and visual self-confrontation in psychotherapy
… problems in treating one client's sessions in a quasi-public manner with non-professionals which also appears to be involved with anonymity and confidentiality issues.This research was undertaken then, to determine whether there is a differential effect on psychological health due to three …

Essays in Financial Intermediation
… reshapes competition among banks. I exploit quasi-random variation in the exposure to the introduction of Brazil's Pix, an instant payment system, and show that instant payments increase deposit market competition -- small bank deposits rise relative to large banks because Pix allows small …

Modeling and quasi-Monte Carlo simulation of risk in credit portfolios
… Next, to improve the efficiency of simulations, quasi- random sequences were introduced into both the single step and multi-step models by devising several new algorithms involving the Brownian bridge construction and principal component analysis. The simulation results from tests under various …

Essays in Spatial Economics
… with a frictional portfolio choice. Using quasi-experimental evidence from a location-specific French investment tax credit targeted at individual landlords, I evidence a substantial causal impact on transactions, new construction, investor returns, and inwards migration. Long-distance …

Essays on Race in Policing
… (4) Traffic; and (5) Deescalation. We exploit quasi-random variation in the timing of when individual officers receive training and estimate a series of event study models. We find that training has little to no effect on policing behavior in terms of either racial composition or stops or …

Sampling Methods in Ray-Based Global Illumination
… a scene), and numerical integration using random or quasi-random sampling. While ray tracing and sampling methods in global illumination have progressed much in the last two decades, the goal of fast and accurate simulation of light transport remains elusive. This dissertation presents a …
