This body of work seeks to define Direct Spatial Antenna Modulation (DSAM) as a new and unique approach to data symbol modulation and phased array control by comparing and contrasting the technique to conventional approaches. A rigorous development of the theoretical and practic…

Tunable optical filters have many applications in optical communication, multispectral and hyper-spectral imaging, bio-sensing, and display application. In optical communication, tunable optical filters (TOF) are used extensively in different wavelength division multiplexed (WDM…
Cytokinesis is the process in which two independent daughter cells are generated from one parent cell following mitosis. Completion of mitosis requires microtubule dependent transport of membranes to the midbody. The research presented in this thesis demonstrates a cytokinetic r…
Vitamin A deficiency continues to be a public health problem in many countries. Several carotenoids, such as α- and β-carotene and β-cryptoxanthin found in plants, are capable of forming vitamin A in humans. Pro-vitamin A carotenoid-rich foods are an important and often sole sou…
Thiosemicarbazones are a class of compounds which have been extensively studied for their anti-proliferative biological properties. The biological properties include antitumor, antibacterial, antiviral and antimalarial, with many diseases studied and reported in the literature. …
Sound cannot travel in a vacuum, physically or socially. The ways in which sound operates are a result of acoustic properties, and the ways by which it is considered to be music are a result of social constructions. Therefore, music is always political, regardless of its content…
One-dimensional (1D) materials have been extensively studied due to their beneficial effects on device performance and interesting and unique material properties. The study of junctions in 1D materials is a natural extension to the physics of nanostructured materials because jun…
This thesis explores several models in continuum mechanics from both local and nonlocal perspectives. The first portion settles a conjecture proposed by Filippo Gazzola and his collaborators on the finite-time blow-up for a class of fourth-order differential equations modeling s…
There is a need for an analytical method to establish a universal criterion for quality of cured vanilla bean. The chemistry of vanilla, one the world’s most popular flavors is extremely complex. As such, no single analytical technique can fully characterize it. Commercially, va…
Organic semiconductors have received a great deal of attention in recent years due to their optoelectronical properties and their potential applications in industry. In this thesis, resonance Raman calculations of a family of organic semiconductor dyes: perylene tetracarboxylic …
This dissertation presents some of our interesting findings, both from a thermodynamic and kinetic point of view, of supramolecular systems in which cucurbit[7]uril is a component. The goal in chapter one is to put our results in perspective, using a selection of related scholar…
In this thesis we consider three topics: the Penrose inequality (PI), polymer corrected gravitational collapse, and zero mode excitations in a RandallSundrum-2 (RS2) cosmological braneworld model. In chapter 2, we attempt to construct a counterexample to the PI using prolate sph…
Our present work represents a comprehensive theoretical and computational research in quest for predicting new photocatalysts suitable for photoelectrochemical process (PEC) to produce hydrogen by splitting water. We predict a new photocatalyst, CuBiW2O8 that exhibits some promi…
The main goal of the present work is to develop a reconstruction scheme for the signals being linear combinations of the shifts of one or more known functions and their derivatives (in one or several variables). We call this class "shift-generated signals". Many important signal…
A definition of fractional Fourier transform as the generalization of ordinary Fourier transform is given at the beginning. Then due to optical reasons the fractional transform of a so-called chirp functions is considered in both theory and practical simulations. Because of a qu…
The desire to forecast or to guess what the future entails is part of human nature. Businesses cannot operate without estimating future demand for their products or services. The problem is that forecasts often fail to meet leadership expectations who desire obtaining the most a…
Le petit ARN régulateur RyhB joue un rôle clé dans la régulation de l'homéostasie du fer chez Escherichia coli. En réprimant de façon post-transcriptionnelle une vingtaine de gènes codant des protéines non essentielles utilisant le fer, RyhB permet l'adaptation rapide de la bact…
Preconditioning is essential for the reduction of computations in solving large linear systems. Murphy, Golub and Wathen [1] propose the block diagonal and block triangular Schur complement preconditioners for systems of saddle-point form. In this thesis, we introduce new block …
