Using Discrete Event Simulation to Model the Benefits of VMI and CPFR
(University of Waterloo, 2013-01-23)Collaborative Planning, Forecasting, and Replenishment or CPFR, is a cooperative business methodology where supply chain members exchange demand information and develop a single shared forecast. CPFR promises to improve ... -
Using Divergent Nozzle with Aerodynamic Lens to Focus Nanoparticles
(University of Waterloo, 2019-03-03)ANSYS Fluent will be used to simulate Computational Fluid Dynamics (CFD) for an efficient lens and nozzle design which will be explained in this paper. We have designed and characterized an aerodynamic lens and a divergent ... -
Using Finite Element Modeling to Gain Insights into the Mechanics of Wound Healing in Drosophila
(University of Waterloo, 2013-01-25)Although it is not difficult to observe the healing of induced wounds in animal embryos, mapping the forces that drive lesion closure has proved challenging. Laser microsurgery, Atomic Force Microscopy (AFM) and other ... -
Using Folsomia candida to Test the Toxicity of Weathered Petroleum-impacted Field Soils before and after Phytoremediation
(University of Waterloo, 2014-05-01)The Canadian Council of Ministers of the Environment (CCME) developed guidelines for petroleum hydrocarbon (PHC) impacted field soils based on the “worst case” scenario of a fresh petroleum spill (CCME, 2001b; CCME, 2008b). ... -
Using Geographic Relevance (GR) to contextualize structured and unstructured spatial data
(University of Waterloo, 2019-09-12)Geographic relevance is a concept that has been used to improve spatial information retrieval on mobile devices, but the idea of geographic relevance has several potential applications outside of mobile computing. Geographic ... -
Using GIS and Remote Sensing Techniques for Solar Panel Installation Site Selection
(University of Waterloo, 2013-09-27)Solar energy replacing conventional non-renewable energy has been widely implemented around the world. Currently, one of the most challenging problems is how to improve the efficiency of producing solar energy. Before ... -
Using Infinite Server Queues Theory In Stress Testing
(University of Waterloo, 2016-12-05)In this thesis, we propose and study a framework to model stress testing, using an infinite server queues theory, such that this framework is aligned with and integrates several existing frameworks currently used in the ... -
Using integer programming in finding t-designs
(University of Waterloo, 2012-04-26)A t-design is a combinatorial structure consisting of a collection of blocks over a set of points satisfying certain properties. The existence of t-designs given a set of parameters can be reduced to finding nonnegative ... -
Using IR Thermography to Evaluate Temperature Distributions on a Diesel NOx Adsorber Catalyst during Simulated Operation
(University of Waterloo, 2007-07-06)In emissions catalyst applications, an axial distribution of reaction, surface chemistry, and temperature all exist on or along the surface of the catalyst. Understanding these distributions is very important in developing ... -
Using Isotopes to Understand the Origin of Water and the Effect of Reinjection in the Los Azufers Geothermal Field in Mexico
(University of Waterloo, 2017-01-25)Los Azufers geothermal system is a convective-type geothermal system located northwest of Mexico City in the state of Michoacán at Mexico. Improvements in geochemical techniques enable a better investigation of the Tertiary ... -
Using Least Squares to Construct Improved Clough-Tocher Interpolant
(University of Waterloo, 2018-01-08)In this thesis, a quartic Clough-Tocher interpolation scheme is introduced, and additional modifications, to adjust the macro-boundary and the order of continuity across domain triangles, are provided to improve both the ... -
Using Long Term Risk Factors from the Ontario Mental Health Reporting System (OMHRS) dataset to predict suicide admission and suicide severity among acute psychiatric inpatients in Ontario, Canada
(University of Waterloo, 2021-05-04)The main purpose of this study was to investigate the relationships between multidimensional long term suicide risk factors (LTRF) and short-term suicide related outcomes known as early warning signs (EWS) among a cross-section ... -
