The Durability of Airfield Concrete Exposed to Aircraft De-icers
(University of Waterloo, 2007-10-01)A large portion of an airport property is occupied by runways and taxiways, which must be kept in excellent condition to ensure the safety of the airplanes, and the people on board. Any free objects on the airfield can ... -
The durability of concrete using concrete plant wash water
(University of Waterloo, 2007-06-18)Hundreds of ready-mix concrete trucks are dispatched daily from ready-mix concrete plants. On average, a concrete truck has a carrying capacity ranging from 7 to 9 cubic metres of concrete, requiring about 1500 litres of ... -
Durability of Reinforced Concrete Incorporating Recycled Concrete as Aggregate(RCA)
(University of Waterloo, 2006)Abstract, <br /> The interest in using recycled construction materials is derived from the growth in construction and demolition waste due to rehabilitation and natural and technological disasters. The driving force for ... -
Durable High Surface Area Electrodes for Rechargeable Zinc Air Batteries
(University of Waterloo, 2015-05-21)People have shown significant interest in metal air batteries throughout history due to their high energy storage capacities, safety, and low cost. These batteries do not require oxygen, one of their constituent fuels, to ... -
Duration Data Analysis in Longitudinal Survey
(University of Waterloo, 2003)Considerable amounts of event history data are collected through longitudinal surveys. These surveys have many particularities or features that are the results of the dynamic nature of the population under study and of ... -
Dust Near Galactic HII Regions
(University of Waterloo, 2012-11-15)The distributions of physical properties, such as the temperature, mass, or density of the dust grains in molecular clouds near Galactic massive star forming regions are relatively poorly understood. These properties are ... -
The Duty to Consult and Environmental Assessments: A Study of Mining Cases from across Canada
(University of Waterloo, 2015-05-01)In 2004, two pivotal court cases, Haida First Nation v. British Columbia (Minister of Forests) and Taku River Tlingit First Nation v. British Columbia (Project Assessment Director), were heard by the Supreme Court of Canada. ... -
Dwelling In Motion: Reinterpreting Flinders Street Station as Urban Public Landscape
(University of Waterloo, 2006)Flinders Street Station in Melbourne, Australia currently serves a dual purpose, providing both a transient space that links the city to its suburban roots and creating a physical barrier between the city and its watercourse. ... -
Dwellings for the Goryan: Re-crafting Bulgarian Post-Soviet Identity at the Site of the Friendship Monument
(University of Waterloo, 2020-09-18)My interest begins in present day Bulgaria at the prominent site of a ruined Soviet monument which the country’s previous communist regime built in 1979. Their monuments expressed communist philosophy through their ... -
A Dynamic Account of the Structure of Concepts
(University of Waterloo, 2011-08-31)Concepts are widely agreed to be the basic constituents of thought. Amongst philosophers and psychologists, however, the question of how concepts are structured has been a longstanding problem and a locus of disagreement. ... -
Dynamic Analysis and Obstacle Avoidance of Autonomous Tractor Semi-Trailers
(University of Waterloo, 2020-09-03)This thesis fills the research gap of the tractor semi-trailer left turn problem at a city intersection. Although obstacle avoidance is a classic topic in the field of autonomous driving, however, most research is focused ... -
Dynamic and Quasi-Static Response of Warm and Hot Formed Aluminum Beams Under Three-Point Bending
(University of Waterloo, 2018-01-23)This thesis investigates the effect of elevated temperature forming on the impact resistance of three aluminum alloys, AA6013-T6, AA7075-T6, and a developmental 7000-series alloy (designated AA7xxx-T76). Both die quenching ... -
Dynamic Balance and Gait Metrics for Robotic Bipeds
(University of Waterloo, 2019-06-19)For legged robots to be useful in the real world, they must be able to balance and walk reliably. Both of these abilities improve when a system is more effective at moving itself around relative to its contacts (i.e., ... -
Dynamic Behaviour of Coke Drums PSVs During Blocked Outlet Condition
(University of Waterloo, 2009-05-01)The maximum yield taken in an oil refinery can not exceed 70% without including Delayed Coker Unit (DCU) as part of unit operations in the refinery. This implies naturally a big attraction on investing of such a unit for ... -
A Dynamic Control Approach to Modeling and Analysing the Effects of Rewards on Behaviour and Attitude Change
(University of Waterloo, 2010-09-28)Motivated by the dynamic feedback nature of human attitudes and behaviours, this work adopts a control systems engineering approach to studying a psychological system. In particular, two discrete-time nonlinear attitude-behaviour ... -
Dynamic Control Strategies Used by ACL-Deficient Copers and Non-Copers during Stair Climbing
(University of Waterloo, 2008-10-23)Background: Osteoarthritis (OA), the most common form of arthritis, is a disorder that affects bi-articular synovial joints and is characterized as the focal loss of articular cartilage with changes to the subchondral and ... -
Dynamic Crowdsourcing Consensus Tasks with Workers That Can Learn
(University of Waterloo, 2016-01-21)Crowdsourcing has become one of the most popular topics in both academia and industry in the past few years. By hiring workers online, task assigners can take advantage of the wisdom of the crowd and solve problems that ... -
Dynamic effects of harnessing cables on distributed parameter systems for space applications: Analytical modeling and experimental validation
(University of Waterloo, 2020-12-02)Power and data signal cables constitute a major component of lightweight spacecraft and satellite structures. These cables can account for up to as high as 30% of the structural mass and hence significantly impact the ... -
Dynamic Factored Particle Filtering for Context-Specific Correlations
(University of Waterloo, 2007-05-15)In order to control any system one needs to know the system's current state. In many real-world scenarios the state of the system cannot be determined with certainty due to the sensors being noisy or simply missing. In ... -
Dynamic HW/SW Partitioning: Configuration Scheduling and Design Space Exploration
(University of Waterloo, 2007-05-18)Hardware/software partitioning is a process that occurs frequently in embedded system design. It is the procedure of determining whether a part of a system should be implemented in software or hardware. This dissertation ...
