Stochastic Nested Aggregation for Images and Random Fields
(University of Waterloo, 2007-05-11)Image segmentation is a critical step in building a computer vision algorithm that is able to distinguish between separate objects in an image scene. Image segmentation is based on two fundamentally intertwined components: ... -
Stochastic Perishable Inventory Systems: Dual-Balancing and Look-Ahead Approaches
(University of Waterloo, 2016-12-23)We study a single-item, multi-period, stochastic perishable inventory problem under both backlogging and lost-sales circumstances, with and without an order capacity constraint in each period. We first model the ... -
Stochastic Power Management Strategy for in-Wheel Motor Electric Vehicles
(University of Waterloo, 2014-05-14)In this thesis, we propose a stochastic power management strategy for in-wheel motor electric vehicles (IWM-EVs) to optimize energy consumption and to increase driving range. The driving range for EVs is a critical issue ... -
A Stochastic Programming Model for a Day-Ahead Electricity Market: a Heuristic Methodology and Pricing
(University of Waterloo, 2009-06-18)This thesis presents a multi-stage linear stochastic mixed integer programming (SMIP) model for planning power generation in a pool-type day-ahead electricity market. The model integrates a reserve demand curve and shares ... -
Stochastic Reconstruction and Morphological Studies of Catalyst Layers of Proton Exchange Membrane Fuel Cells
(University of Waterloo, 2021-11-26)Durability is one of the main obstacles that inhibits the commercialization of polymer electrolyte membrane (PEM) fuel cells for transport applications, in which the microstructure of catalyst layers (CL) under dynamic ... -
Stochastic Renewal Process Model for Condition-Based Maintenance
(University of Waterloo, 2009-08-31)This thesis deals with the reliability and maintenance of structures that are damaged by shocks arriving randomly in time. The degradation is modeled as a cumulative stochastic point process. Previous studies mostly adopted ... -
Stochastic Renewal Process Models for Maintenance Cost Analysis
(University of Waterloo, 2011-05-03)The maintenance cost for an engineering system is an uncertain quantity due to uncertainties associated with occurrence of failure and the time taken to restore the system. The problem of probabilistic analysis of maintenance ... -
Stochastic Renewal Process Models for Structural Reliability Analysis
(University of Waterloo, 2018-09-05)Reliability analysis in structural engineering is utilized in the initial design phase and its application continues throughout the service life of a structural system in form of maintenance planning and optimization. ... -
Stochastic Stability of Flow-Induced Vibration
(University of Waterloo, 2008-05-07)Flow-induced structural vibration is experienced in many engineering applications, such as aerospace industry and civil engineering infrastructures. One of the main mechanisms of flow-induced vibration is instability which ... -
Stochastic stability of viscoelastic systems
(University of Waterloo, 2008-05-15)Many new materials used in mechanical and structural engineering exhibit viscoelastic properties, that is, stress depends on the past time history of strain, and vice versa. Investigating the behaviour of viscoelastic ... -
Stochastic Stepwise Ensembles for Variable Selection
(University of Waterloo, 2009-04-30)Ensembles methods such as AdaBoost, Bagging and Random Forest have attracted much attention in the statistical learning community in the last 15 years. Zhu and Chipman (2006) proposed the idea of using ensembles for variable ... -
Stochastic Volatility Models and Simulated Maximum Likelihood Estimation
(University of Waterloo, 2011-08-02)Financial time series studies indicate that the lognormal assumption for the return of an underlying security is often violated in practice. This is due to the presence of time-varying volatility in the return series. The ... -
Stone it was Stone it Remained: The Evolution of Architecture on the Azores island of Pico
(University of Waterloo, 2023-05-24)The culture of building with volcanic stone on the Portuguese Azorean Island of Pico represents the resilience of human creativity. The original settlers of this isolated Atlantic Island were faced with an adverse ... -
“Stop paddling and see where we are”: A postcolonial mobile deconstruction of environmental discourses (re)produced on summer camp canoe trips through Algonquin Park
(University of Waterloo, 2019-04-30)Residential summer camp canoe trippers are important. They are agents of socialization who amalgamate their campers into socially constructed accepted regimes of truth (Csikszentmihalyi, 1981; Grimwood, Gordon & Stevens, ... -
Storage Matters: Managing Grain, Securing Finance, and Building Markets
(University of Waterloo, 2016-06-15)This dissertation analyzes the nexus of agriculture and finance, specifically the mediating role of grain storage. How grain markets are organized and governed is foundational to food security. Hundreds of millions of ... -
Storage System Management Using Reinforcement Learning Techniques and Nonlinear Models
(University of Waterloo, 2009-01-21)In this thesis, modeling and optimization in the field of storage management under stochastic condition will be investigated using two different methodologies: Simulation Optimization Techniques (SOT), which are usually ... -
Storey-Based Stability Analysis for Multi-Storey Unbraced Frames Subjected to Variable Loading
(University of Waterloo, 2008-07-23)For decades, structural engineers have been using various conventional design approaches for assessing the strength and stability of framed structures for various loads. Today, engineers are still designing without some ... -
