• Sampling-based Predictive Database Buffer Management 

  Vanderkooy, Theodore (University of Waterloo, 2023-09-25)

  This thesis presents a database buffer caching policy that uses information about long- running scans to estimate future accesses. These estimates are used to approximate the optimal caching policy, which requires knowledge ...

• High Level Concurrency in C∀ 

  Parsons, Colby (University of Waterloo, 2023-09-25)

  Concurrent programs are notoriously hard to write and even harder to debug. Furthermore concurrent programs must be performant, as the introduction of concurrency into a program is often done to achieve some form of speedup. ...

• The Pair Cache Problem 

  Khodaee, SayedMohammadAmin (University of Waterloo, 2023-09-25)

  This thesis investigates the pair cache problem, a unique variation of the classic cache replacement problem where each element is stored in two pages, and the cache only needs one of these pages to respond to a query. The ...

• Mindless Scroll: An Infinite Scroll Abstract Colouring App for Mindfulness 

  Zassman, Saralin (University of Waterloo, 2023-09-25)

  We design and evaluate Mindless Scroll, a mobile application for mindfulness that encourages a slow and deliberate approach to colouring. The app renders an infinite scroll of generated geometric tilings that reveal ...

• LOW-RESOLUTION CUSTOMIZABLE UBIQUITOUS DISPLAYS 

  Irudayaraj, Antony Albert Raj (University of Waterloo, 2023-09-22)

  In a conventional display, pixels are constrained within the rectangular or circular boundaries of the device. This thesis explores moving pixels from a screen into the surrounding environment to form ubiquitous displays. ...

• Fire Detection using RF Signals 

  Ma, Kai (University of Waterloo, 2023-09-20)

  Structural fires can be a major threat to life and property. Contemporary smoke alarms suffer from drawbacks such as long response times, lack of penetration through walls, and nuisance (false-positive) alarms. In this ...

• Effective Math-Aware Ad-Hoc Retrieval based on Structure Search and Semantic Similarities 

  Zhong, Wei (University of Waterloo, 2023-09-15)

  Despite the prevalence of digital scientific and educational contents on the Internet, only a few search engines are capable to retrieve them efficiently and effectively. The main challenge in freely searching scientific ...

• Differentially-private Multiparty Clustering 

  Ahmed, Abdelrahman (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 ...

• Transforming the Reading Experience of Scientific Documents with Polymorphism 

  Masson, Damien (University of Waterloo, 2023-09-07)

  Despite the opportunities created by digital reading, documents remain mostly static and mimic paper. Any improvement in the shape or form of documents has to come from authors who contend with current digital formats, ...

• Information Access Using Neural Networks For Diverse Domains And Sources 

  Xie, Yuqing (University of Waterloo, 2023-09-05)

  The ever-increasing volume of web-based documents poses a challenge in efficiently accessing specialized knowledge from domain-specific sources, requiring a profound understanding of the domain and substantial comprehension ...

• Compiler-Based Approach to Enhance BliMe Hardware Usability 

  Duan, Xiaohe (University of Waterloo, 2023-09-05)

  Outsourced computing has emerged as an efficient platform for data processing, but it has raised security concerns due to potential exposure of sensitive data through runtime and side-channel attacks. To address these ...

• Perceptions and Practicalities for Private Machine Learning 

  Kacsmar, Bailey (University of Waterloo, 2023-09-01)

  data they and their partners hold while maintaining data subjects' privacy. In this thesis I show that private computation, such as private machine learning, can increase end-users' acceptance of data sharing practices, ...

• Enabling Language-Specific Transformations in Language-Agnostic Program Reduction 

  Zhao, Gaosen (University of Waterloo, 2023-08-30)

  When a program P triggers a bug in a language implementation, program reduction can reduce P by removing program elements that are irrelevant to the bug, to facilitate debugging. Program reduction has been widely used in ...

• FJMP: Factorized Joint Multi-Agent Motion Prediction 

  Rowe, Luke (University of Waterloo, 2023-08-30)

  Multi-agent motion prediction is an important problem in an autonomous driving pipeline, and it involves forecasting the future behaviour of multiple agents in complex driving environments. Autonomous vehicles (AVs) should ...

• A Bias-Variance-Privacy Trilemma for Statistical Estimation 

  Regehr, Matthew (University of Waterloo, 2023-08-28)

  The canonical algorithm for differentially private mean estimation is to first clip the samples to a bounded range and then add noise to their empirical mean. Clipping controls the sensitivity and, hence, the variance of ...
