Dynamic accident sequence analysis using dynamic flowgraph method and Markov/cell-to-cell mapping technique
(2018-07-01)
In the recent years, numerous concerns have been raised regarding the capabilities and adequacy of classical probabilistic safety assessment (PSA) techniques (fault/event tree) to account for dynamic system interactions ...
A Computational Fluid Dynamics based model that predicts wall shear stress in CANDU outlet feeder pipes
(2018-01-01)
Wall thinning of carbon steel in CANDU reactor outlet feeder pipes due to Flow Accelerated Corrosion (FAC) is identified as one of the challenges for CANDU reactors since it would force them to shut down due to safety ...
Systems and models for secure fallback authentication
(2018-12-01)
Fallback authentication (FA) techniques such as security questions, Email resets, and SMS resets have significant security flaws that easily undermine the primary method of authentication. Security questions have been shown ...
Examining the affordances and constraints of using infographics in pre-service teacher education
(2018-04-13)
Infographics are a communication tool that can be used to share large amounts of data in a more aesthetically pleasing and understandable way. The production and consumption of infographics encourages students to develop ...
Analyzing the impact of BYOD in secondary school English classrooms
(2018-08-01)
There is limited research on Bring Your Own Device (BYOD) programs. This study explored the impact of a BYOD program on secondary school students’ engagement, learning process, and learning performance in English classrooms. ...
A directional preference ETX measure for the collection tree protocol in mobile sensor networks
(2018-01-01)
There has been a growing interest in Wireless Sensor Networks (WSN) that utilizes mobile nodes for various purposes. These mobile wireless sensor networks tend to suffer from constant link breakages mainly caused by connected ...
Implementation of power electronics in nuclear power plants: DC electrical system conceptual design and its financial analysis
(2018-05-01)
A Power Electronic (PE) device is a semiconductor-based device which enable many advanced conversion of electricity which have been used widely in many industries. Due to the recent development in both circuit design and ...
Passive damping mechanism of Herschel-Quincke tubes for pressure pulsations in piping systems
(2018-12-01)
The acoustic pressure pulsations in industrial piping systems can induce fluctuating loads on inline equipment which may cause fatigue failure and in severe cases, initiate a phenomenon known as acoustic resonance. Passive ...
Design and analysis of an active underbody aerodynamic device for tractor trailers
(2018-04-01)
At highway speeds, up to 65 % of the total energy used by large trucks is for overcoming aerodynamic drag. The underbody region of a tractor-trailer is responsible for up to 30 % of the aerodynamic drag on tractor-trailers, ...
Development and investigation of an ammonia synthesis reactor
(2018-08-01)
Ammonia production has gained increasing attention in the last decade due to its importance as a feedstock and an energy carrier. In the present thesis study, two novel ammonia production systems are presented. The first ...
