Hack: Reclaiming the Commons
(University of Waterloo, 2013-05-03)Architecture is an act of agency, and a technology that can be learned by anyone for their own purpose. It evolved as a system of organization and a protective shell for our fragile bodies, a vast, complex technology that ... -
Hants County, 45º6’10”N 63º44’2”W
(University of Waterloo, 2016-01-22)How can regionalism and modern building practices synthesize to develop a localized building culture? While regionally conscientious modern architecture demands efficiency, sustainable resource equilibrium may be the ... -
Happiness within the Uncanny: Revitalizing the Street Level in Hong Kong's New Town
(University of Waterloo, 2022-05-16)Hong Kong is the physical embodiment of neoliberalism at all levels of society, and the city itself is seen as a domain for private corporations to generate profit, creating spaces that are purely functional and generic. ... -
Haptic Training Simulator for Pedicle Screw Insertion in Scoliosis Surgery
(University of Waterloo, 2015-02-20)This thesis develops a haptic training simulator that imitates the sensations experienced by a surgeon in pedicle screw insertions in a scoliosis surgery. Pedicle screw insertion is a common treatment for fixing spinal ... -
The Haptiverse: A Platform for Reuse of Haptic Content
(University of Waterloo, 2021-12-23)Research into haptic technology has accelerated over the past decade, producing more devices and content than ever before. However, due to the innate diversity of its hardware and the sense of touch itself, existing haptic ... -
HARDI Denoising using Non-local Means on the ℝ³ x 𝕊² Manifold
(University of Waterloo, 2012-01-05)Magnetic resonance imaging (MRI) has long become one of the most powerful and accurate tools of medical diagnostic imaging. Central to the diagnostic capabilities of MRI is the notion of contrast, which is determined by ... -
The Hardness of Learning Access Control Policies
(University of Waterloo, 2023-08-30)The problem of learning access control policies is gaining significant attention in research. We contribute to the foundations of this problem by posing and addressing meaningful questions on computational hardness. Our ... -
Hardware Design and Implementation of an Electromagnetic Levitation System in an Additive Manufacturing Environment
(University of Waterloo, 2022-04-29)Magnetic Levitation and Additive Manufacturing are two promising fields with ever growing interest in several industrial settings. There is, however, negligible overlap between the two fields. This research aims to combine ... -
Hardware Implementation of a High Speed Deblocking Filter for the H.264 Video Codec
(University of Waterloo, 2012-04-25)H.264/MPEG-4 part 10 or Advanced Video Coding (AVC) is a standard for video compression. MPEG-4 is currently one of the most widely used formats for recording, compression and distribution of high definition video. One ... -
Hardware Implementation of Barrett Reduction Exploiting Constant Multiplication
(University of Waterloo, 2019-10-01)The efficient realization of an Elliptic Curve Cryptosystem is contingent on the efficiency of scalar multiplication. These systems can be improved by optimizing the underlying finite field arithmetic operations which are ... -
Hardware Implementation of Fixed-Point Decoder for Low-Density Lattice Codes
(University of Waterloo, 2022-04-29)Low-density lattice codes (LDLCs) are a special class of lattice codes that can be decoded efficiently using iterative decoding and approach the capacity of the additive white Gaussian noise (AWGN) channel. The construction ... -
Hardware Implementation of Soft Computing Approaches for an Intelligent Wall-following Vehicle
(University of Waterloo, 2007-05-18)Soft computing techniques are generally well-suited for vehicular control systems that are usually modeled by highly nonlinear differential equations and working in unstructured environment. To demonstrate their applicability, ... -
Hardware Implementations of the Lightweight Welch-Gong Stream Cipher Family using Polynomial Bases
(University of Waterloo, 2019-01-28)In this thesis we develop a parametrized generic hardware implementation for the Welch-Gong (WG) stream cipher family for low power and low cost applications. WG stream ciphers operate over finite fields, and are comprised ... -
Hardware Implementations of the WG-16 Stream Cipher with Composite Field Arithmetic
(University of Waterloo, 2014-09-22)The WG stream cipher family consists of stream ciphers based on the Welch-Gong (WG) transformations that are used as a nonlinear filter applied to the output of a linear feedback shift register (LFSR). The aim of this ... -
