Efficient Temporal Synopsis of Social Media Streams
(University of Waterloo, 2013-08-07)Search and summarization of streaming social media, such as Twitter, requires the ongoing analysis of large volumes of data with dynamically changing characteristics. Tweets are short and repetitious -- lacking context and ... -
Efficient Transaction Processing for Short-Lived Transactions in the Cloud
(University of Waterloo, 2014-01-23)The cloud, in the past few years, has become the preferred platform for hosting web applications. Many of these web applications store their data in a distributed cloud storage system, which greatly simplifies application ... -
Efficient treatment of climate data uncertainty in ensemble Kalman filter (EnKF) based on an existing historical climate ensemble dataset
(Elsevier, 2019-01)Successful data assimilation depends on the accurate estimation of forcing data uncertainty. Forcing data uncertainty is typically estimated based on statistical error models. In practice, the hyper-parameters of statistical ... -
Efficient Triplet Exciton Fusion in Molecularly Doped Polymer Light-Emitting Diodes
(Wiley, 2017-04-04)Solution-processed polymer organic light-emitting diodes (OLEDs) doped with triplet-triplet annihilation (TTA)upconversion molecules, including 9,10-diphenylanthracene, perylene, rubrene and TIPS-pentacene, are reported. ... -
Efficient Trust Region Subproblem Algorithms
(University of Waterloo, 2011-09-29)The Trust Region Subproblem (TRS) is the problem of minimizing a quadratic (possibly non-convex) function over a sphere. It is the main step of the trust region method for unconstrained optimization problems. Two cases may ... -
Efficient Zero-Knowledge Proofs and Applications
(University of Waterloo, 2014-08-12)Zero-knowledge proofs provide a means for a prover to convince a verifier that some claim is true and nothing more. The ability to prove statements while conveying zero information beyond their veracity has profound ... -
An Effort Prediction Framework for Software Defect Correction
(University of Waterloo, 2008-08-29)Developers apply changes and updates to software systems to adapt to emerging environments and address new requirements. In turn, these changes introduce additional software defects, usually caused by our inability to ... -
Egalitarian yet Unequal? Gender Stereotyping in Romantic Relationships
(University of Waterloo, 2018-08-31)In three studies (Ns = 225, 182, 378), heterosexual participants reported their career / family priorities, plus those of their romantic partner, in 10-15 years. Predictions for romantic partners’ career / family goals ... -
Eggly: Designing Mobile Augmented Reality Neurofeedback Training Games for Children with Autism Spectrum Disorder
(University of Waterloo, 2023-07-19)Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder that affects how children communicate and relate to other people and the world around them. Emerging studies have shown that neurofeedback training (NFT) games ... -
Ehrhart Theory and Unimodular Decompositions of Lattice Polytopes
(University of Waterloo, 2015-01-20)Ehrhart theory studies the behaviour of lattice points contained in dilates of lattice polytopes. We provide an introduction to Ehrhart theory. In particular, we prove Ehrhart's Theorem, Stanley Non-negativity, and ... -
Eicosapentaenoic Acid and Docosahexaenoic Acid in Whole Blood Are Differentially and Sex-Specifically Associated with Cardiometabolic Risk Markers in 8-11-Year-Old Danish Children
(Public Library of Science, 2014-10-15)n-3 long-chain polyunsaturated fatty acids improve cardiovascular risk markers in adults. These effects may differ between eicosapentaenoic acid (EPA, 20:5n-3) and docosahexaenoic acid (DHA, 22:6n-3), but we lack evidence ... -
Eigenvalue, Quadratic Programming and Semidefinite Programming Bounds for Graph Partitioning Problems
(University of Waterloo, 2014-09-03)The Graph Partitioning problems are hard combinatorial optimization problems. We are interested in both lower bounds and upper bounds. We introduce several methods including basic eigenvalue and projected eigenvalue ... -
Elasca: Workload-Aware Elastic Scalability for Partition Based Database Systems
(University of Waterloo, 2013-05-14)Providing the ability to increase or decrease allocated resources on demand as the transactional load varies is essential for database management systems (DBMS) deployed on today's computing platforms, such as the cloud. ... -
Elastic Actuator Line modelling for the Wake-induced Fatigue Analysis of Horizontal Wind Turbine
(University of Waterloo, 2018-09-25)The fatigue damage on wind turbine blades will threaten the safety and stability of the wind turbine and thus lower the efficiency and economy of the power generation system. The wake-induced fatigue plays an important ... -
Elastic moduli of multiblock copolymers in the lamellar phase
(AIP Publishing, 2004-02-22)We study the linear elastic response of multiblock copolymer melts in the lamellar phase, where the molecules are composed of tethered symmetric AB diblock copolymers. We use a self-consistent field theory method, and ... -
Elastic-Plastic Fatigue Crack Growth Analysis under Variable Amplitude Loading Spectra
(University of Waterloo, 2009-05-13)Most components or structures experience in service a variety of cyclic stresses. In the case of cyclic constant amplitude loading the fatigue crack growth depends only on the crack, the component geometry and the applied ... -
An Elasto-Visco-Plastic Multiscale Model for Fibrous Unidirectional Composite Materials
(University of Waterloo, 2016-08-24)This research thesis investigates the capability of predicting the elasto-visco-plastic material response and failure of a unidirectional composite material. A constitutive framework is developed to incorporate the elastic, ... -
