(University of Waterloo, 2010-02-16)Modern solid-state nuclear magnetic resonance (NMR) methodologies are applied to investigate two spin-5/2 nuclei, Zn-67 and Al-27, in different coordination environments in order to characterize the magnitudes and orientations ... -
Solidification in laser powder deposition of Ti-Nb alloys
(University of Waterloo, 2011-08-12)The size and morphology of the dendrite growth patterns are simulated for laser powder deposition of Ti-Nb alloys under steady-state and transient growth conditions. A phase field model using an adaptive grid technique was ... -
Solution Strategies in Short-term Scheduling for Multitasking Multipurpose Plants
(University of Waterloo, 2018-05-09)This thesis addresses challenges in short-term scheduling of multipurpose facilities using mathematical optimization. Such approach involves the formulation of a predictive model and an objective function, and the development ... -
Solution-processable oligomeric and small molecule semiconductors for organic solar cells
(University of Waterloo, 2016-06-08)Organic solar cells appear as a promising technology within photovoltaic field owing to their low-cost fabrication and their great flexibility enabling a widespread distribution. For now, they are still at the prototype ... -
Solutions to Mitigate Cross-Phase Modulation Impairment in Coherent Fiber-Optic Communications
(University of Waterloo, 2020-01-27)In this thesis, methods of exploiting and consequently, mitigating the nonlinearities in Cross-Phase Modulation (XPM) dominated ber-optic communication is suggested using the model provided by Ciena Corporation. An ... -
Solvent production by the hyperthermophilic archaeon Hyperthermus butylicus
(University of Waterloo, 2021-08-27)Hyperthermus butylicus is one of the few hyperthermophilic (organisms that thrive in temperatures 80°C and above) archaea that can produce 1-butanol as a major fermentation end-product. The reported end-products (acetone, ... -
Solvent-Induced Nanoscopic Surface Morphology on Polymer Thin Films
(University of Waterloo, 2020-09-29)Polymer thin films are studied extensively due to their important applications in the fields of material coatings, biomedical devices, nanoelectronics, and more. Many of these applications directly depend on the surface ... -
Solving Geometric Problems in Space-Conscious Models
(University of Waterloo, 2009-01-26)When dealing with massive data sets, standard algorithms may easily ``run out of memory''. In this thesis, we design efficient algorithms in space-conscious models. In particular, in-place algorithms, multi-pass algorithms, ... -
Solving Hyperbolic PDEs using Accelerator Architectures
(University of Waterloo, 2009-07-27)Accelerator architectures are used to accelerate the simulation of nonlinear hyperbolic PDEs. Three different architectures, a multicore CPU using threading, IBM’s Cell Processor, and Nvidia’s Tesla GPUs are investigated. ... -
Solving mathematical problems on touch-based devices
(University of Waterloo, 2014-09-17)Research on the use of mobile touch-based devices for mathematics has not kept up with the increasing ubiquity of such machines. Building upon MathBrush, a pen-based system for the recognition of handwritten mathematics, ... -
Solving Saddle Point Formulations of Linear Programs with Frank-Wolfe
(University of Waterloo, 2023-08-24)The problem of solving a linear program (LP) is ubiquitous in industry, yet in recent years the size of linear programming problems has grown and continues to do so. State-of-the-art LP solvers make use of the Simplex ... -
Solving Traveling Salesman Problem With a non-complete Graph
(University of Waterloo, 2010-01-07)One of the simplest, but still NP-hard, routing problems is the Traveling Salesman Problem (TSP). In the TSP, one is given a set of cities and a way of measuring the distance between cities. One has to find the shortest ... -
Some additive results in F_q[t]
(University of Waterloo, 2015-08-27)We collected several results in integers of additive number theory and translated to results in F_q[t]. The results we collected are related to slim exceptional sets and the asymptotic formula in Waring's problem, a ... -
