Differentially Private Online Aggregation
(University of Waterloo, 2022-01-13)Database operations are often performed in batch mode, i.e. the analyst issuing the query must wait till the database has been processed in its entirety before getting feedback. Batch mode is inadequate for large databases ... -
Differentially Private Searchable Symmetric Encryption Scheme with Configurable Pattern Leakage
(University of Waterloo, 2019-12-19)Searchable symmetric encryption (SSE) allows a data owner to outsource its data to a cloud server while maintaining the ability to search over it. Most existing SSE schemes leak access-pattern leakage, and thus are vulnerable ... -
Differentially Private Simple Genetic Algorithms
(University of Waterloo, 2021-12-13)We study the differentially private (DP) selection problem, where the goal is to select an item from a set of candidates that approximately maximizes a given objective function. The most common solution to this problem is ... -
Differentially-private Multiparty Clustering
(University of Waterloo, 2023-09-13)In an era marked by the widespread application of Machine Learning (ML) across diverse domains, the necessity of privacy-preserving techniques has become paramount. The Euclidean k-Means problem, a fundamental component ... -
Differentiating Gait Behaviors between Early-Stage Dementia with Lewy Bodies and Parkinson’s Disease
(University of Waterloo, 2023-01-20)Dementia with Lewy bodies (DLB) and Parkinson’s disease (PD) can be difficult to differentially diagnose, given the overlap in clinical and pathological features. Evidence suggests gait may be a sensitive and selective ... -
The Differing Influences of Soil Moisture and Antecedent Soil Moisture on the Timing and Magnitude of N2O Production
(University of Waterloo, 2012-10-22)Riparian soils are thought to be potential hotspots for nitrous oxide (N2O) fluxes from incomplete denitrification, with soil moisture cited as a primary controller, however, because there are multiple potential pathways ... -
Diffuse Solid-Fluid Interface Method for Dispersed Multiphase Flows
(University of Waterloo, 2018-08-30)Industrial chemical engineering processes such as bubble columns, reactors and separators involve multiphase flows of two or more fluids. In order to improve the design and operation of these processes, an understanding ... -
Diffusion-Reaction Modeling, Non-Linear Dynamics, Feedback, Bifurcation and Chaotic Behaviour of the Acetylcholine Neurocycle and Their Relation to Alzheimer's and Parkinson's Diseases
(University of Waterloo, 2010-04-29)The disturbances and abnormalities occurring in the components of the Acetylcholine (ACh) neurocycle are considered one of the main features of cholinergic sicknesses like Parkinson’s and Alzheimer’s diseases. A fundamental ... -
Digging Online: Crowdfunding for Archaeology
(University of Waterloo, 2017-01-17)Archaeology permits us precious glimpses into the mysterious past, captivating the public with its intrigue. However, the expensive nature of archaeological work often leads to a struggle for funding. Crowdfunding allows ... -
A Digital Agricultural Revolution: Ontario Grain Farmer Perceptions of Digital Farming and Big Data
(University of Waterloo, 2019-08-14)Digital technologies and big data are revolutionizing agriculture, but the implications for equity and sustainability are uncertain. From big data climate forecasts and massive robotic tractors, to satellite pest control ... -
Digital Craft | In Search of a Method of Personal Expression Within the Digital
(University of Waterloo, 2018-01-23)Our relationship with the digital has fundamentally changed within the past decade. A mesh of outside interests have been efficiently folding themselves into our lives. These exist as either a legion of hosted “free” web ... -
Digital Darwin: Editing The Loves of the Plants as a Case Study of the Theory and Practice of Digital Editions
(University of Waterloo, 2016-04-26)Digital scholarly editing is an evolving field that allows for the rendering of complex print works that are rife with paratextual material. Erasmus Darwin’s The Loves of the Plants represents this kind of paratextually ... -
Digital Dialogism: Space, Time, and Queerness in Video Games
(University of Waterloo, 2023-05-04)Video games are multimodal pieces of media; they communicate meaning through many layers of signification including aural, visual, narrative, mechanical, and more. To understand the ways that games communicate meaning and ... -
Digital Innocence
(University of Waterloo, 2010-12-16)Screens mediate an ever-increasing part of our experience today. While the space within our screens is indispensable - as perceptually ‘real’ as embodied experience itself - this space tends to exclude the hands and body ... -
Digital Predistortion of Frequency-Multipliers-Based Wideband Millimeter-Wave Sources
(University of Waterloo, 2020-01-16)Radio frequency (RF) technology has seen unprecedented advancements over the past few decades. These advancements have been driven by continuously growing demand for wireless networks with higher capacity and radar and ... -
Digital Predistortion of Millimeter-Wave Phased Antenna Arrays
(University of Waterloo, 2018-09-07)The cost of deployment of reliable, high-throughput, fifth-generation (5G) millimeter-wave (mm-wave) base stations will depend significantly on the maximum equivalent isotropically radiated power (EIRP) that the base ... -
Digital Radio Encoding and Power Amplifier Design for Multimode and Multiband Wireless Communications
(University of Waterloo, 2013-04-25)The evolution of wireless technology has necessitated the support of multiple communication standards by mobile devices. At present, multiple chipsets/radios operating at predefined sets of modulation schemes, frequency ... -
