Mobile apps (or apps) are software applications developed to run on mobile devices such as smartphones and tablets, among other devices. The number of apps has grown tremendously since Apple opened the first app store in 2008. For example, in March of 2009 the Google Play app st…
Nowadays, the forces of globalization, on the one hand, have shaped the world’s economic environment and on the other hand, led to the increased importance of economic integration. Hence, a faster growth of corporations and countries after they integrated is not a big surprise. …
Due to high proficiency with high bandwidth efficiency, orthogonal frequency division multiplexing (OFDM) has been selected for broadband wireless communication systems. Since OFDM can provide large data rates with sufficient robustness to radio channel impairments, and due to i…
Metric embeddings constitute one of the fundamental tools for exploiting the underlying geometric structure of many combinatorial problems. In this dissertation we study some of the applications of metric embeddings in the fileld of computer science and resolve some of the previ…
Fiber Reinforced Polymer (FRP) composite materials provide effective and potentially economic solution for rehabilitating and upgrading the existing reinforced and precast concrete bridge structures that have suffered deterioration. Each year, there are a significant number of d…
Two nonlinear pushover analyses and three displacement-controlled time history analyses of two precast concrete panel assemblies were completed. The analytical software used was SAP2000 (version 15.0.0). The precast concrete panel modeled was a three-dimensional single panel con…
This study investigates how the combination of steel fiber, crumb rubber, synthetic fiber, and conventional steel cage will improve the ductility of regular concrete pipes and thin-walled semi-rigid concrete pipes. In this study, pipes with four different concrete mixtures were …
Microelectromechanical system (MEMS) resonators have been a subject of research for more than four decades. The reason is the huge potential they possess for frequency applications. The use of a MEMS resonator as the timing element has an experimental history and huge progress h…
Extensible Markup Language (XML) is a de facto standard for data exchange in the World Wide Web. Indexing plays a key role in improving the execution of XML queries over that data. In this thesis we discuss the three main categories of indexes proposed in the literature to handl…
Atherosclerosis is a vascular disease that reduces arterial lumen size through plaque deposition and arterial wall thickening. The pathological complications of atherosclerosis, namely heart disease and stroke, remain the leading cause of mortality in the world. The most common …
The aim of this research is to develop and build a low cost portable integrated frequency-domain and continuous wave (CW) system for real-time spectroscopic imaging of human tissue. This system measures four tissue chromophore concentrations (water, lipid, deoxygenated, and oxyg…
Electron beam lithography (EBL) is the leading technology for versatile two dimensional patterning at the deep (10-100 nm) nanoscale. In addition to its reputation as an enabling technology for next generation advances in industry, its ease of use, accuracy, and cost has made it…
With the recent advancements in semiconductor manufacturing towards smaller, faster and more efficient microelectronic systems, the problems of increasing leakage current and reduced breakdown voltage in bulk-CMOS transistors have become substantial in the sub-100-nanometer era.…
Despite the fact that engineering components and structures are carefully designed against fatigue failures, 50 to 90% of mechanical failures are due to fatigue crack development. The severity of the failure depends on both the crack length and its orientation. Many types of sen…
TiO2 nanotube arrays are promising candidates for applications such as photocatalysis and for potential employment in spin-electronic (spintronic) devices. The functionality of TiO2 -based nanotubes is highly dependent on their structure (microstructure and crystallographic symm…
The McMurray Formation contains complex geological features that were partially formed in a fluvial-estuarine depositional environment. These geological features that are interrelated to each other exist with different shapes, patterns, and sizes. The inclined heterolithic strat…
The structural dynamics behavior of the blade of a horizontal axis wind turbine that reacts to the different components of the aerodynamic loading were studied by many researchers using different approaches and assumptions. In the present research, the author considered all the …
Photoreceptor cell degeneration due to disease may lead to loss of visual acuity. With the recent availability of adaptive optics (AO) and spectral domain optical coherence tomography (SD-OCT) imaging systems, it is now possible to image the retina at the cellular level. Many of…
