Bimodal Gate Oxide Breakdown in Sub-100 nm CMOS Technology
(University of Waterloo, 2008-12-19)In the last three decades, the electronic industry has registered a tremendous progress. The continuous and aggressive downsizing of the transistor feature sizes (CMOS scaling) has been the main driver of the astonishing ... -
Design and Analysis of Metastable-Hardened, High-Performance, Low-Power Flip-Flops
(University of Waterloo, 2011-08-17)With rapid technology scaling, flip-flops are becoming more susceptible to metastability due to tighter timing budgets and the more prominent effects of process, temperature, and voltage variation that can result in frequent ... -
Determination of the fracture strength of brittle material thin films at high temperature using MEMS
(University of Waterloo, 2020-01-27)Brittle materials are widely used as structural materials in microelectromechanical systems (MEMS). Their mechanical properties make them suitable for high-temperature environments where MEMS are exposed to different types ... -
Development of Analysis Tools for the Facilitation of Increased Structural Steel Reuse
(University of Waterloo, 2016-08-11)Reuse of structural steel can be more attractive than recycling in many cases, if associated costs and risks are lowered, and if externalities are considered. The costs and risks typically associated with steel reuse arise ... -
Distribution System Planning and Reliability Assessment under High DG Penetration
(University of Waterloo, 2010-02-11)With power system restructuring, continuous growth of demand, and deregulation, small, scattered generators referred to as Distributed Generation (DG) are predicted to play a key role in the power distribution system. ... -
Enhancing System Reliability Utilizing Private Electric Vehicle Parking Lots Accounting for the Uncertainties of Renewables
(University of Waterloo, 2019-09-19)Integration of renewable energy sources into electric grids comes with significant challenges. The produced energy from renewable sources such as wind and solar is intermittent, non-dispatchable and uncertain. The uncertainty ... -
Evaluation and Calibration of Pedestrian Bridge Standards for Vibration Serviceability
(University of Waterloo, 2017-08-14)An increase in the use of lightweight materials and emphasis on architecturally appealing designs has resulted in lively pedestrian bridges. A prominent example for this is the serviceability failure of the London Millenium ... -
Multi-Microgrids Reliability and Islanding Operation Enhancement, under Different Dispatchable-Renewable DG Units Penetration Levels
(University of Waterloo, 2012-05-18)Electrical reliability assurance is a very important aspect of electrical power systems; significant consideration should be given to reliability at both the planning and operation stage of power systems. A decrease in ... -
Multi-State Reliability Analysis of Nuclear Power Plant Systems
(University of Waterloo, 2012-08-20)The probabilistic safety assessment of engineering systems involving high-consequence low-probability events is stochastic in nature due to uncertainties inherent in time to an event. The event could be a failure, repair, ... -
New Approaches to Composite Reliability Assessment of Smart Power Systems
(University of Waterloo, 2017-05-12)Electric power networks are complex systems because of their geographic spread and the consequent need for interconnections and integration of different components such as generators, transformers, lines, reactors, relays, ... -
On Error Detection and Recovery in Elliptic Curve Cryptosystems
(University of Waterloo, 2011-08-16)Fault analysis attacks represent a serious threat to a wide range of cryptosystems including those based on elliptic curves. With the variety and demonstrated practicality of these attacks, it is essential for cryptographic ... -
Probabilistic Models for Life Cycle Management of Energy Infrastructure Systems
(University of Waterloo, 2007-08-02)The degradation of aging energy infrastructure systems has the potential to increase the risk of failure, resulting in power outage and costly unplanned maintenance work. Therefore, the development of scientific and ... -
R2Fix: Automatically Generating Bug Fixes from Bug Reports
(University of Waterloo, 2013-01-08)Many bugs, even those that are known and documented in bug reports, remain in mature software for a long time due to the lack of the development resources to fix them. We propose a general approach, R2Fix, to automatically ... -
