Query Optimization in Dynamic Environments
(University of Waterloo, 2012-05-08)Most modern applications deal with very large amounts of data. Having to deal with such huge amounts of data is in itself a challenge. This challenge is complicated even more by the fact that, in many cases, this data is ... -
Query Similarity for Community Question Answering System Based on Recurrent Encoder Decoder
(University of Waterloo, 2017-01-18)The measurement of sentence similarity is a fundamental task in natural language processing. Traditionally, it is measured either from word-level or sentence-level (such as paraphrasing), which requires many lexical and ... -
A Query-Based Approach for the Analysis of Aspect-Oriented Systems
(University of Waterloo, 2007-01-29)In recent years, many aspect-oriented languages and methods have been proposed in the literature to support separation of concerns that can be spread throughout a software system and its components and to facilitate ... -
Querying Large Collections of Semistructured Data
(University of Waterloo, 2013-10-01)An increasing amount of data is published as semistructured documents formatted with presentational markup. Examples include data objects such as mathematical expressions encoded with MathML or web pages encoded with XHTML. ... -
The quest for "diagnostically lossless" medical image compression using objective image quality measures
(University of Waterloo, 2015-02-18)Given the explosive growth of digital image data being generated, medical communities worldwide have recognized the need for increasingly efficient methods of storage, display and transmission of medical images. For this ... -
Question Paraphrase Generation for Question Answering System
(University of Waterloo, 2015-08-31)The queries to a practical Question Answering (QA) system range from keywords, phrases, badly written questions, and occasionally grammatically perfect questions. Among different kinds of question analysis approaches, the ... -
Questioning the Unquestioned: Scale Development to Assess Ecotourist Ethics
(University of Waterloo, 2009-04-30)While most ecotourist definitions and typologies have relied on concepts ingrained in traveler behaviours or destinations, none has benefited from a consideration of personal ethics. The study of ecotourism has virtually ... -
Queueing Analysis of a Priority-based Claim Processing System
(University of Waterloo, 2009-10-02)We propose a situation in which a single employee is responsible for processing incoming claims to an insurance company that can be classified as being one of two possible types. More specifically, we consider a priority-based ... -
A Queueing Model to Study Ambulance Offload Delays
(University of Waterloo, 2008-09-24)The ambulance offload delay problem is a well-known result of overcrowding and congestion in emergency departments. Offload delay refers to the situation where area hospitals are unable to accept patients from regional ... -
Queueing Network Models of Ambulance Offload Delays
(University of Waterloo, 2012-09-27)Although healthcare operations management has been an active and popular research direction over the past few years, there is a lack of formal quantitative models to analyze the ambulance o oad delay problem. O oad delays ... -
Quick and Automatic Selection of POMDP Implementations on Mobile Platform Based on Battery Consumption Estimation
(University of Waterloo, 2014-04-01)Partially Observable Markov Decision Process (POMDP) is widely used to model sequential decision making process under uncertainty and incomplete knowledge of the environment. It requires strong computation capability and ... -
A Quick-and-Dirty Approach to Robustness in Linear Optimization
(University of Waterloo, 2013-01-07)We introduce methods for dealing with linear programming (LP) problems with uncertain data, using the notion of weighted analytic centers. Our methods are based on high interaction with the decision maker (DM) and try ... -
QuickAssist Extensive Reading for Learners of German Using CALL Technologies
(University of Waterloo, 2010-12-20)The focus of this dissertation is the development and testing of a CALL tool which assists learners of German with the extensive reading of German texts of their choice. The application provides functionality that enables ... -
Quiet In The Rear: The Wehrmacht and the Weltanschauungskrieg in the Occupation of the Soviet Union
(University of Waterloo, 2018-04-26)Historians widely acknowledge that the Second World War witnessed a substantial degree of ideology in the conflict itself. This paper will establish the degree to which the ideology of National Socialism shaped the Wehrmacht’s ... -
R-D Optimal Scalable Video Coding Using Soft Decision Quantization
(University of Waterloo, 2010-11-22)In this thesis, we study the concept of scalable video coding as implemented in the extension to the H.264 video coding standard. Specifically, for the spatial and quality scalability scenarios, we propose an optimization ... -
R.A.M: Remote Arctic Memory
(University of Waterloo, 2015-09-22)The modern world is defined by networks. One network, specifically, has become the core component in how our societies function; the Internet. While the Internet may seem ubiquitous, seamless, and imperceptible, it is only ... -
R2Fix: Automatically Generating Bug Fixes from Bug Reports
(University of Waterloo, 2013-01-08)Many bugs, even those that are known and documented in bug reports, remain in mature software for a long time due to the lack of the development resources to fix them. We propose a general approach, R2Fix, to automatically ... -
Radar-based Human Pulse Sensing
(University of Waterloo, 2024-05-10)This thesis presents a novel approach where a superstrate is used to re-purpose a commercial off-the-shelf mm-wave 60 GHz radar by Infineon (BGT60TR13C) for near-field human pulse sensing. The superstrate is realized through ... -
RADARSAT-2 Polarimetric Radar Imaging for Lake Ice Mapping
(University of Waterloo, 2017-11-21)Changes in lake ice dates and duration are useful indicators for assessing long-term climate trends and variability in northern countries. Lake ice cover observations are also a valuable data source for predictions with ... -
