Title: NUMERICAL STUDY OF MICRO, MESO, AND MACRO-MECHANICAL BEHAVIOR OF COHESIONLESS GRANULAR MATERIALS USING 3D DEM ROLLING/TWISTING RESISTANCE MODELS

Show moreIt has been frequently demonstrated that the mechanical behavior of cohesionlessgranular materials including sand and gravel is significantly influenced by theirmorphological features including the shape and surface texture. Therefore, the primaryobjective of this thesis is to take a more critical look at micro-, meso- and macromechanicalbehaviors of cohesionless granular materials in response to effective modelingof the grains morphology and to establish a practical yet straightforward causal relationshipbetween micro-scale modeling and macro-scale soil behavior.To precisely investigate the effects of morphology on the macroscopic behavior, aparticle-based microscopic approach using the Discrete Element Method (DEM) wasemployed. In this regard, a novel 3D micro-mechanical contact model, based on the MTL(moment transfer law) theory, incorporating both rolling and twisting resistances, waspicked to describe the inter granular behavior between cohesionless particles. Severaltriaxial and direct shear tests were run to characterize link (s), if any, between the microscalefeatures and the macroscopic soil responses. Results from these tests were analyzedat both the peak and critical state. Through the development of a comprehensive calibrationmethodology and finding a reasonable match between numerical and experimental results,it was found that even in the ideal case of perfectly spherical grains, it is still possible toeffectively model the presence and effects of influential micro-scale morphologicalfeatures without the need for direct modeling of geometrical complexities followed bychallenging issues such as limitations in computational resources and almost unresolvabledifficulties in tracing the evolution of the modeled morphology during the loading.

Title: DESIGN, SYNTHESIS AND CHARACTERIZATION OF NOVEL MATERIALS TO CONSTRUCT HIGH-ENERGY-DENSITY RECHARGEABLE CELLS

Show moreABSTRACTRechargeable electrical energy storage cells, especially lithium-ion cells, are the critical technology that realized the great development of the portable electronic devices, such as laptop computers and cell phones. But in some other areas, such as the renewable energy industries and electrical vehicles, which are developing fast and more and more important for environment protection, the current rechargeable energy storage cells cannot meet their requirements, because of their limited energy density.Two types of cells, lithium sulfur batteries (LSBs) and supercapacitors, are attracting peoples’ attention for their potential to be developed as the future high-energy-density rechargeable cells. However, Li-S batteries are suffering from the fast discharging capacity fading, which is still a barrier for the large-scale commercialization. Although supercapacitors have been widely used in various areas, their energy density is much lower than current lithium-ion batteries, which limited their application only in assistant systems, such as regenerative brakes.To solve these problems, novel design for both the electrode material and electrolytes are required. In this thesis work, we focused our study in four areas: (1) New electrolytes for LSBs; (2) Cathode material for LSBs; (3) Activated carbon electrodes for electrical double layer capacitors (EDLCs); and (4) Electrolyte formulations for EDLCs. We investigated three types of new compounds as a co-solvent for the electrolyte of LSBs: fluorinated ethers, fluoroether sulfones and sulfonium ILs, which have improved the discharging capacity and cycling stability of LSBs. A novel S@HCN@MnO2 cathode material was designed and synthesized, which performed excellent long-term performance. A novel porous AC material with very high SSA was synthesized, and EDLCs with new electrolyte formulations were tested, which showed wide electrochemical potential window and high energy density.

Title: GUARANTEED, ADAPTIVE, AUTOMATIC ALGORITHMS FOR UNIVARIATE INTEGRATION: METHODS, COSTS AND IMPLEMENTATIONS

Show moreThis thesis investigates how to solve univariate integration problems using numerical methods, including the trapezoidal rule and the Simpson's rule. Most existing guaranteed algorithms are not adaptive and require too much a priori information. Most existing adaptive algorithms do not have valid justification for their results. The goal is to create adaptive algorithms utilizing the two above-mentioned methods with guarantees. The classes of integrands studied in this thesis are cones. The algorithms are analytically proved to be a success if the integrand lies in the cone. The algorithms are adaptive and automatically adjust the computational costs based on the integrand values. The lower and upper bounds on the computational costs for both algorithms are derived. The lower bounds on the complexity of the problems are derived as well. By comparing the upper bounds on the computational cost and the lower bounds on the complexity, our algorithms are shown to be asymptotically optimal. Numerical experiments are implemented.

Title: House museums In Chicago: a re-examination of motives, origins, and transformations of the institutions

Show moreA house museum is a former residence converted into a publicly accessible structure, which preserves an identity of its original domestic history. These houses shelter a wide variety of institutions with a diverse range of imperatives and services. With a focus on Chicago house museums, this dissertation seeks an overarching pattern underlying this conversion and reuse of residential buildings. This dissertation focuses on six house museums in Chicago: the Palmer Castle, the Harding Castle, the Clarke House, the Glessner House, the Madlener House and the Robie House. The Palmer and Harding Castles ceased to exist as house museums and are no longer standing.Conventional archival research conducted during the initial phases yielded historiographies that corroborate as well as contradict popular stories about the process by which the houses were preserved, salvaged and converted. Key primary-source research includes interviews with persons involved in—and observant of—motivations and forces in play upon these six case studies. Texts of the interviews are included in appendices. The dissertation reveals how select individuals (acting variously as architects, historians, concerned citizens, and leaders of institutions) influenced the creation of the six house museums. This dissertation contains a chronicle and an evaluation of the values which informed and influenced the house museum condition in Chicago in an environment which largely pre-dated the historic building preservation movement in America. The case studies show that the persons and parties involved in saving various houses for reuse did not generally execute definitive plans, in full, with a clear ultimate goal. Instead, in all cases, individuals and small groups of people fought an array of idiosyncratic battles, often yielding short-term victories. Economic pressures, political conditions, and societal values evolve, ushering in new opportunities and new dangers for nascent institutions inhabiting former residences. As each generation of directors, curators and governing boards mature and matriculate, the goals and objectives which influenced the reuse of their house museums changed. The very notion of attaining some sort of permanent statis has been found, through this research, to be elusive. Dynamism in both the people and the institution reusing these house museums can yield positive outcomes ensuring preservation of the institution of the house museum.

Title: A Novel Non-parametric Density Estimation Approach to Measuring Muon Ionization Cooling and Reverse Emittance Exchange in the MICE Experiment

Show moreThe Muon Ionization Cooling Experiment (MICE) located at Rutherford Appleton Laboratory in the U.K. has demonstrated muon ionization beam cooling for the first time. A beam of muons in MICE is produced from high-energy proton beam collision with a fixed target, generating pions which in turn decay into muons. Pion-decay muons, thus, are tertiary particles and, as a result, occupy a large volume in position‒momentum phase space. To fit the muon beam into smaller and more cost-effective accelerating devices, muon beam phase‒space volume needs to be reduced (beam cooling). Ionization beam cooling, which before MICE has never been demonstrated experimentally for muons, is the only technique fast enough to be used for muons within their short lifetime. Ionization cooling occurs when muons traverse an absorbing material and lose momentum through ionization energy loss. The cooling effect in MICE is measured using two scintillating-fiber tracking detectors. These trackers, one upstream and one downstream of the absorber, reconstruct and measure the position and momentum coordinates of each muon. Given the precision MICE needed to demonstrate beam cooling, it is necessary to develop analysis tools that can account for any effects that may lead to inaccurate measurement of cooling, such as non‒linear effects in beam optics. Non‒parametric density estimation techniques, such as kernel density estimation (KDE), provide a basis for creating analysis tools that are robust against these effects, directly calculating the muon beam phase-space density and volume for demonstrating beam cooling. This thesis focuses on the application of KDE to the measurement of beam cooling in MICE. The KDE technique is validated using known distributions and is applied to simulated and experimental MICE data corresponding to the various magnet, optics, and absorber configurations. Using the KDE technique, muon beam cooling in the four‒dimensional transverse phase space, as well as reverse emittance exchange using MICE data have been demonstrated.

Show moreNowadays, one can use social media and other online platforms to communicate with friends and family, write a review for a product, ask questions about a topic of interest, or even share details of private life with the rest of the world. The ever-increasing amount of user-generated content has provided researchers with data that can offer insights on human behavior. Because of that, the field of computational social science - at the intersection of machine learning and social sciences - has soared in the past years, especially within the field of public health research. However, working with large amounts of user-generated data creates new issues. In this thesis, we propose solutions for two problems encountered in computational social science and related to confounding bias.First, because of the anonymity provided by online forums, social networks, or other blogging platforms through the common usage of usernames, it is hard to get accurate information about users such as gender, age, or ethnicity. Therefore, although collecting data on a specific topic is made easier, conducting an observational study with this type of data is not simple. Indeed, when one wishes to run a study to measure the effect of a variable on another variable, one needs to control for potential confounding variables. In the case of user-generated data, these potential confounding variables are at best noisily observed or inferred and at worst not observed at all. In this work, we wish to provide a way to use these inferred latent attributes in order to conduct an observational study while reducing the effect of confounding bias as much as possible. We first present a simple matching method in a large-scale observational study. Then, we propose a method to retrieve relevant and representative documents through adaptive query building in order to build the treatment and control groups of an observational study.Second, we focus on the problem of controlling for confounding variables when the influence of these variables on the target variable of a classification problem changes over time. Although identifying and controlling for confounding variables has been assiduously studied in empirical social science, it is often neglected in text classification. This can be understood by the fact that, if we assume that the impact of confounding variables does not change between the training and the testing data, then prediction accuracy should only be slightly affected. Yet, this assumption often does not hold when working with user-generated text. Because of this, computational science studies are at risk of reaching false conclusions when based on text classifiers that are not controlling for confounding variables. In this document, we propose to build a classifier that is robust to confounding bias shift, and we show that we can build such a classifier in different situations: when there are one or more observed confounding variables, when there is one noisily predicted confounding variable, or when the confounding variable is unknown but can be detected through topic modeling.
