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 ... -
Some Applications of Hyperbolic Geometry in String Perturbation Theory
(University of Waterloo, 2019-08-19)In this thesis, we explore some applications of recent developments in the hyperbolic geometry of Riemann surfaces and moduli spaces thereof in string theory. First we show how a proper decomposition of the moduli space ... -
Some Aspects of Arsenic and Antimony Geochemistry in High Temperature Granitic Melt – Aqueous Fluid System and in Low Temperature Permeable Reactive Barrier – Groundwater System
(University of Waterloo, 2008-02-11)Arsenic and antimony are important trace elements in magmatic-hydrothermal systems, geothermal systems and epithermal deposits, but their partitioning behavior between melt and aqueous fluid is not well understood. The ... -
Some aspects of Cantor sets
(University of Waterloo, 2014-03-28)For every positive, decreasing, summable sequence $a=(a_i)$, we can construct a Cantor set $C_a$ associated with $a$. These Cantor sets are not necessarily self-similar. Their dimensional properties and measures have been ... -
Some Aspects of Distribution System Planning in the Context of Investment in Distributed Generation
(University of Waterloo, 2009-08-27)A paradigm shift in distribution system design and planning is being led by the deregulation of the power industry and the increasing adoption of distributed generation (DG). Technology advances have made DG investments ... -
Some Aspects of Microgrid Planning and Optimal Distribution Operation in the Presence of Electric Vehicles
(University of Waterloo, 2012-01-16)Increase in energy demand is one of the major challenges that utilities are faced with, thus resulting in an increase in environmental pollution and global warming. The transport sector has a significant share of the energy ... -
Some Aspects of Static and Dynamic Distribution System State Estimation with Optimal Meter Placement Studies
(University of Waterloo, 2018-09-04)In a power distribution system, due to the evolution of Active Distribution Networks (ADNs), there is a possibility of violation of the system operational constraints. A state estimator provides an approximate snapshot ... -
