a-Si:H-Silicon Hybrid Low Energy X-ray Detector
(University of Waterloo, 2014-09-15)Low energy X-ray (< 20 keV) detection is a key technological requirement in applications such as protein crystallography or diffraction imaging. Silicon based optical cameras based on CCDs or CMOS imaging chips coupled to ... -
Absorption of Nitric Oxide from Flue Gas Using Ammoniacal Cobalt(II) Solutions
(University of Waterloo, 2013-01-24)Air emissions from the combustion of fossil fuel, including carbon dioxide, sulfur dioxide, nitrogen dioxide and nitric oxide, have caused severe health and environmental problems. The post-combustion wet scrubbing has ... -
Abstraction and Refinement Techniques for Ternary Symbolic Simulation with Guard-value Encoding
(University of Waterloo, 2022-05-20)We propose a novel encoding called guard-value encoding for the ternary domain {0, 1, X}. Among the advantages it has over the more conventional dual-rail encoding, the flexibility of representing X with either of <0, 0> ... -
Acausal Modelling of Thermal Fluid Systems with a Focus on Engine Air Path Components
(University of Waterloo, 2020-09-14)The automotive industry is rapidly developing more advanced vehicle propulsion systems, autonomous driving, emissions reduction, and improved fuel efficiency. Optimal control theory has evolved such that a system can be ... -
Acausal Powertrain Modelling with Application to Model-based Powertrain Control
(University of Waterloo, 2014-02-21)The automotive industry has long been searching for efficient ways to improve vehicle performance such as drivability, fuel consumption, and emissions. Researchers in the automotive industry have tried to develop methods ... -
Acceleration and Heating of Metal Particles in Condensed Matter Detonation
(University of Waterloo, 2010-04-30)For condensed explosives containing metal particle additives, interaction of the detonation shock and reaction zone with the solid inclusions leads to non-ideal detonation phenomena. Features of this type of heterogeneous ... -
Accommodating a High Penetration of PHEVs and PV Electricity in Residential Distribution Systems
(University of Waterloo, 2015-04-22)Global warming is threatening the world’s delicate ecosystems to the point where the extinction of numerous species is becoming increasingly likely. Experts have determined that avoiding such a disaster requires an 80% ... -
Accommodating a High Penetration of Plug-in Electric Vehicles in Distribution Networks
(University of Waterloo, 2014-05-12)The last few decades have seen growing concern about climate change caused by global warming, and it now seems that the very future of humanity depends on saving the environment. With recognition of CO2 emissions as the ... -
Accounting for the Effects of Power System Controllers and Stability on Power Dispatch and Electricity Market Prices
(University of Waterloo, 2005)Recently, the widespread use of power system controllers, such as PSS and FACTS controllers, has led to the analysis of their effect on the overall stability of power systems. Many studies have been conducted to allocate ... -
Acoustic Monitoring for Leaks in Water Distribution Networks
(University of Waterloo, 2020-04-21)Water distribution networks (WDNs) are complex systems that are subjected to stresses due to a number of hydraulic and environmental loads. Small leaks can run continuously for extended periods, sometimes indefinitely, ... -
Active Acoustics for Monitoring Unreported Leaks in Water Distribution Networks
(University of Waterloo, 2021-09-08)Water distribution networks (WDNs) are critical infrastructure elements conveying water through thousands of kilometers of pipes. Pipes - one of the most critical elements in such systems - are subjected to various structural ... -
Active Aerodynamic Modification of Wind Turbine Blades to Reduce Load Fluctuation
