Polymeric foam materials continue to gather commercial and research interests due to their unique physical characteristics and emerging applications in a wide variety of industries. This research work viewed the polymer foam industry...
Linear low density polyethylenes (LLDPEs are substantially linear polyethylenes [(C2H4)n]ย with randomly distributed 1-alkyl short chain branches. The presence of branches on the ethylene backbone sharply reduces the crystallinity level...
A substantial amount of work exists for tensor regression analysis in a variety of clinical settings, including neuroimaging, genomics, and dental medicine. Our motivation for this paper is from a study of periodontal disease (PD) with a...
Electrophoresis is one of the most powerful tools used to separate biological molecules by size in a supporting medium under the influence of an electric field. Pluronic F127 gel, introduced as a new sieving medium for electrophoresis in...
It is common to encounter skewed response data in medicine, epidemiology and health care studies. Methodology needs to be devised to overcome the natural difficulties that occur in analyzing such data particularly when it is multivariate...
All-solid-state batteries are promising energy storage systems that improve safety by replacing the flammable and hazardous liquid electrolytes with chemically and structurally stable solid electrolytes. Polymer electrolytes are...
Colloidal suspensions transform between fluid and disordered solid states when parameters such as the colloid volume fraction and the strength and nature of the colloidal interactions are varied. Seemingly subtle changes in the...
Understanding Slow Dynamics in Polymers Using Coarse-Grained Molecular Dynamics Simulations: Microphase Separation in Block Copolyelectrolytes and Photo-Switching in Azobenzene-Polymers
Tracking slow dynamics in polymers is very challenging using all-atomistic molecular dynamics simulations due to the vast range of time scales involved. Therefore, there are urgent needs to develop coarse-grained modeling schemes to meet...
Fluid dynamic characterization of shock impingement on a flat surface has been studied extensively, whereas the material behavior induced by the shock has largely been ignored. The focus of this study is mainly on the material and...
The study of melt miscibility and structure-property relations of different types of polyolefins provide an important pathway to material design for different applications. In this work we study melt and crystalline properties of blends...
In this thesis, we study the entanglement properties of quantum systems to characterize quantum phases and phase transitions. We focus on the free fermion lattice systems and we use numerical calculation to verify our ideas. Behavior of...
This dissertation explores the integration of quantum electrodynamics (QED) with electronic structure theory to accurately model and understand complex light-matter interactions within optical cavities. Clever designs of optical cavities...
At the same temperature, below 0oC, the saturation vapor pressure (SVP) over ice is slightly less than the SVP over liquid water. Numerical models use the Clausius-Clapeyron relation to calculate the SVP and relative humidity, but there...
There is a growing demand for technology that can sense people and objects without imposing excessive overhead. Traditional solutions usually require people to wear additional devices on their bodies and install cumbersome sensors on...
This dissertation presents a survey of ab initio models developed based on the merger of multireference (MR) methods and density functional theory (DFT) in order to provide an accurate and efficient description of electron correlation...
Polyethylenes with functional groups precisely placed on a fixed number of backbone carbons have been recently synthesized via acyclic diene metathesis (ADMET), polycondensation and ring-opening metathesis polymerization (ROMP). The...
Electrophoresis as an analytical technique has made considerable contributions to the separations and analysis of macromolecules in biology-related research. Pluronic gels, which are composed of orderly packed spherical micelles...
Prostate Specific Antigen (PSA) is a widely accepted marker of prostate cancer recurrence. Genitourinary surgeons and oncologists are particularly interested in whether a surgery using robotic device improves times to PSA recurrence...
The diurnal variations from a high-resolution regional climate model (Regional Spectral Model; RSM) are analyzed from 6 independent decade long integrations using lateral boundary forcing data separately from the National Centers for...
Interest in online rating data has increased in recent years in which ordinal ratings of products or local businesses are provided by users of a website, such as Yelp! or Amazon. One source of heterogeneity in ratings is that users apply...
Ensemble learning algorithms are among the most widely used and indispensable tools in machine learning, data science and predictive analytics. Their widespread use can be attributed to the success of ensemble learning algorithms in...
Shear banding, or the discontinuity of shear rate in flowing materials, has been reported for a broad range of industrially important systems, including wormlike micelles, powders, foams, emulsions, and liquid crystalline polymers....
The discovery of carbon nanotubes (CNTs) by Iijima in 1991 has initiated a great deal of scientific research on exploring their unique properties and potential applications. One of the promising applications is integrating CNTs into...
Carbon nanotubes (CNTs) are known to exhibit outstanding mechanical, electrical, thermal, and coupled electromechanical properties. CNTs can be employed towards the design of an innovative strain sensor with enhanced multifunctionality...
The northern Australian rainy season is part of the Asian-Australian monsoon system and occurs during the Austral summer across the northern regions of the continent. The Australian monsoon is responsible for most of the annual rainfall...
Computational Studies of Equilibrium and Non-Equilibrium Phase Diagrams and Critical Properties of Two Physical and Chemical Model Systems with Both Short-Range and Long-Range Interactions or Reactivities
In this dissertation, we introduce long-range interactions into one equilibrium model (Ising model) and one non-equilibrium system (Ziff-Gulari-Barshad model), and study their phase diagrams and critical properties. A new approach to do...
Many of the most important complex systems take the form of networks, including biological systems like neural connections and food webs, technological systems like the Internet and power grids, and social networks like political...
In this dissertation, we address some of the needs faced in the development of modern ab initio quantum chemical methods to compute high-accuracy ground and excited electronic states. Chapters 1 and 2 should be seen as introductory...
Human induced pluripotent stem cells (hiPSCs) are recognized as an excellent alternative to embryonic stem cells in the fields of regenerative medicine, in vitro model construction, and drug discovery. Given the challenge of limited...
