Multi-scale models of T cell activation
… theme of this thesis is to develop and apply multi-scale computational techniques adopted from physical sciences to study a key phenomenon underlying the adaptive immune response: the activation of T cells. The specific objectives are: 1) develop efficient and versatile computational …

Multi-scale models for wafer surface evolution in chemical mechanical planarization
… but generates global thickness variation. Two models, referred as Models I and II, are developed to investigate the pattern structure effect on the post-CMP wafer profile. Model I assumes that the pad asperities contact with the wafer directly. In developing this model, at first, the pressure …

Exploring the Stochastic Performance of Metallic Microstructures With Multi-Scale Models
… properties of Ti-7Al. The homogenized macro-scale material properties are directly related to the crystallographic structure at the micro-scale. Furthermore, microstructural uncertainties arising from experiments and computational methods propagate on the material properties used for …

Developing Multi-Scale Models for Water Quality Management in Drinking Water Distribution Systems
… constituents. On the other hand, the huge scale of water distribution systems contributes dramatically to this deterioration mainly due to the long transport times between treatment and consumption points. Hence, utilities face a considerable challenge to efficiently manage the water …

Data-driven PSP linkages for atomistic datasets
For a variety of materials, atomic-scale modeling techniques are commonly employed as a means of investigating fundamental properties, including both structural and chemical responses. While force-field based calculations are significantly less computationally expensive than their …

The Development and Application of Coupled Multiscale Models of Malaria Disease System
The purpose of this thesis is to develop coupled multi-scale dynamics of infectious disease systems. An infectious disease system consists of three subsystems interacting, which are the host, the pathogen, and the environment. Each level has two different interaction scales (micro-scale and …

Translational Modeling of Non-Invasive Electrical Stimulation
… both in vivo and in vitro. Volume conduction models are being applied to these areas of research, especially in the design and analysis of clinical montages. However, additional research on the parameterization of models remains.</p> <p>In this dissertation, Finite Element Method (FEM) models …

Computational and Machine Learning-Reinforced Modeling and Design of Materials under Uncertainty
… designing high-performance materials using multi-scale models plays a significant role to improve the predictability, reliability, proper functioning, and longevity of components for a wide range of applications in the fields of aerospace, electronics, energy, and structural engineering. …

Computational analysis of cell-cell communication in the tumor microenvironment
… interactions in six syngeneic mouse tumor models. To identify specific receptor-ligand interactions that predict tumor growth rate and immune infiltration, we used receptor-ligand interactions as features in regression models. For the third study, we extended our scRNA-seq approach to …

Mechanical response of polymer matrix composites using indentation stress-strain protocols
… However, there remains an intermediary lengthscale on the order of the arrangement of the reinforcing phase which has yet to be satisfactorily characterized. Understanding the properties of this intermediary lengthscale is critical to the development of multi-scale models with predictive …

Distribution and Landscape Attributes of Greater Prairie Chickens and Sharp-Tailed Grouse Outside of Their Traditional Range in South Dakota
… Land-use around these points was analyzed at 7 scales (400, 800, 1200, 1600, 2000, 2400, and 3000-m). 70 grouse leks were found in eastern South Dakota outside of the traditional grouse range. Significantly more grass (grassland and undisturbed grass) was found around grouse leks than non-use …

Optimal Point Charge Approximation: from 3-Atom Water Molecule to Million-Atom Chromatin Fiber
… and straightforward in technical implementation, models based exclusively on atom-centered charge placement, a major workhorse of the biomolecular simulations, do not necessarily provide a sufficiently detailed description of the molecular electrostatic potentials for small systems, and can become …
