Low-Power Soft-Error-Robust Embedded SRAM
(University of Waterloo, 2013-01-08)Soft errors are radiation-induced ionization events (induced by energetic particles like alpha particles, cosmic neutron, etc.) that cause transient errors in integrated circuits. The circuit can always recover from such ... -
Low-Power, Low-Voltage SRAM Circuits Design For Nanometric CMOS Technologies
(University of Waterloo, 2011-08-30)Embedded SRAM memory is a vital component in modern SoCs. More than 80% of the System-on-Chip (SoC) die area is often occupied by SRAM arrays. As such, system reliability and yield is largely governed by the SRAM's performance ... -
Low-Rank Plus Sparse Decompositions of Large-Scale Matrices via Semidefinite Optimization
(University of Waterloo, 2023-05-19)We study the problem of decomposing a symmetric matrix into the sum of a low-rank symmetric positive semidefinite matrix and a tridiagonal matrix, and a relaxation which looks for symmetric positive semidefinite matrices ... -
LOW-RESOLUTION CUSTOMIZABLE UBIQUITOUS DISPLAYS
(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. ... -
Low-temperature characterization of dielectric loss at microwave frequencies in aluminum oxide
(University of Waterloo, 2015-04-09)Superconducting quantum devices have gained increasing interest over the past 15 years because of their role as promising candidates for implementing a large-scale quantum computer and as ultra-sensitive detectors. ... -
A lower bound for the two-variable Artin conjecture and prime divisors of recurrence sequences
(Elsevier, 2019-01-01)In 1927, Artin conjectured that any integer other than −1 or a perfect square generates the multiplicative group (Z/pZ)× for infinitely many p. In 2000, Moree and Stevenhagen considered a two-variable version of this ... -
Lower Bounds and Derandomization
(University of Waterloo, 2008-08-26)A major open problem in complexity theory is to determine whether randomized complexity classes such as BPP, AM, and MA have any nontrivial derandomization. This thesis investigates the derandomization of two randomized ... -
Lower Bounds on Quantum Query and Learning Graph Complexities
(University of Waterloo, 2014-07-22)In this thesis we study the power of quantum query algorithms and learning graphs; the latter essentially being very specialized quantum query algorithms themselves. We almost exclusively focus on proving lower bounds for ... -
Lower Limb Biomechanics in Walking, Running and Cycling: Implications for Overuse Injury
(University of Waterloo, 2019-09-27)A common anecdotal theory among endurance athletes is that cycling results in fewer knee injuries compared to running. This is thought to be due in part to a lower impact ground reaction force in cycling, compared to ... -
Lower order terms of moments of L-functions
(University of Waterloo, 2011-06-17)<p>Given a positive integer k, Conrey, Farmer, Keating, Rubinstein and Snaith conjectured a formula for the asymptotics of the k-th moments of the central values of quadratic Dirichlet L-functions. The conjectured formula ... -
Lower Tail Independence of Hitting Times of Two-Dimensional Diffusions
(Cambridge University Press, 2018)The coefficient of tail dependence is a quantity that measures how extreme events in one component of a bivariate distribution depend on extreme events in the other component. It is well known that the Gaussian copula has ... -
Lox: Protecting the Social Graph in Bridge Distribution
(University of Waterloo, 2022-05-26)Access to the open Internet, free from surveillance and censorship, is an important part of fulfilling the right to privacy. Despite this, in many regions of the world, censorship of the Internet is used to limit access ... -
LP-based Approximation Algorithms for the Capacitated Facility Location Problem
(University of Waterloo, 2012-05-18)The capacitated facility location problem is a well known problem in combinatorial optimization and operations research. In it, we are given a set of clients and a set of possible facility locations. Each client has a ... -
“Lucky that East Germany also exists”: Yugoslavia between the Federal Republic of Germany and the German Democratic Republic (1955-1968)
(University of Waterloo, 2019-01-14)This dissertation explores the relations between Yugoslavia and the Federal Republic of Germany (FRG) and the German Democratic Republic (GDR) in the period between 1955 and 1968. This is the first analysis using sources ... -
Lumbar Spine and Hip Kinematics and Muscle Activation Patterns during Coitus: A comparison of common coital positions
(University of Waterloo, 2013-01-31)Qualitative studies investigating the sexual activity of people with low back pain found a substantial reduction in the frequency of coitus and have shown that pain during coitus due to mechanical factors (i.e., movements ... -
Lumped Elements Loaded Miniaturized Antenna for Bluetooth Enabled Hearing Aid Devices
(University of Waterloo, 2016-01-22)Hearing loss is one of the most common physical and sensory impairments among all ages, especially elders. Hearing loss may affect only one ear or both ears of a patient at a different degree of impairment. This asymmetrical ... -
Lyrics Matter: Using Lyrics to Solve Music Information Retrieval Tasks
(University of Waterloo, 2015-08-06)Music Information Retrieval (MIR) research tends to focus on audio features like melody and timbre of songs while largely ignoring lyrics. Lyrics and poetry adhere to a specific rhyme and meter structure which set them ... -
Lysis of Gram-positive and Gram-negative Bacteria by Antibacterial Porous Polymeric Monolith Formed in Microfluidic Biochips for Sample Preparation
(Springer-Verlag Berlin Heidelberg: Analytical and Bioanalytical Chemistry, 2014-07-25)Bacterial cell lysis is demonstrated using polymeric microfluidic biochips operating via a hybrid mechanical shearing/contact killing mechanism. These biochips are fabricated from a cross-linked poly(methyl methacrylate) ... -
