A study on regulation standard for SMRs
(2019-08-01)The current thinking in the nuclear energy industry is favoring by small-scale Small Modular Reactors (SMRs) with improved safety and multiple applications compared to conventional large-size nuclear power plants. The ... -
Study on specifics of thermalhydraulics and neutronics of pressure-channel supercritical water-cooled reactors (SCWRs)
(2017-08-01)A group of countries has initiated an international collaboration to develop a next generation (i.e., Generation IV) of nuclear reactors. Chosen as one of the six Generation‒IV nuclear-reactor concepts, the SCWRs are ... -
Study on supercritical fluids in an intermediate heat exchanger for an SCWR hydrogen cogeneration system
(2015-12-01)SuperCritical Water-cooled Reactors (SCWRs) are one of six Generation-IV nuclear reactor concepts under development worldwide. SCWRs benefit from an increase in thermal efficiency due to the reactor coolant operating above ... -
A study on the impact of global replacement of fossil fuel based electricity generation, transportation and domestic heating with nuclear generated electricity using a modified VENSIM DICE model
(2021-08-01)While much debated across current media, electricity generation using nuclear energy is proposed as one of the means of addressing the global negative impacts of climate change – notably ongoing accumulation of CO2 in the ... -
Sum-rate maximization for active channels
(2013-04-01)In conventional wireless channel models, there is no control on the gains of different subchannels. In such channels, the transmitted signal undergoes attenuation and phase shift and is subject to multi-path propagation ... -
Sum-rate maximization for two-way active channel with unequal subchannel noise powers
(2016-06-01)Wireless parallel channels refer to certain wireless links, where the information is conveyed from a source to a destination through a set of parallel orthogonal subchannels. In such channels, the transmitted signals undergo ... -
Sum-rate maximization for two-way active channels.
(2014-11-01)In this thesis, the term passive channel refers to the conventional parallel wireless channel model, where there is no control over the gain of each individual subchannel. We de ne an active channel as a parallel channel ... -
Sum-rate optimal network beamforming and power allocation for single-carrier asynchronous bidirectional relay network
(2015-08-01)We study the problem of sum-rate maximization, under a total transmit power budget, for an asynchronous single-carrier bidirectional (two-way) network. The network consists of two single-antenna transceivers which wish to ... -
A supervised machine learning-based framework to detect low-level fault injections in software systems
(2022-08-01)Fault injection attacks inject faults into system components, inducing abnormal software behavior. Software vulnerability analysis cannot prevent new attack vectors without software modifications. Attack detection methods ... -
Supporting Durham Catholic School District teachers in implementing movement integration: understanding and addressing the barriers through teacher coaching
(2020-12-01)Movement integration (MI) is short bursts of physical activity (PA) within classrooms during school hours. Despite cited benefits of MI, it is not well utilized by teachers. MI barriers include lack of time and confidence, ... -
Supporting student success with machine learning and visual analytics
(2019-08-01)Post secondary institutions have a wealth of student data at their disposal. This data has recently been used to explore a problem that has been prevalent in the education domain for decades. Student retention is a complex ... -
A survey of algebraic algorithms in computerized tomography
(2010-08-01)X-ray computed tomography (CT) is a medical imaging framework. It takes measured projections of X-rays through two-dimensional cross-sections of an object from multiple angles and incorporates algorithms in building a ... -
A Survey on Security and Attack Aspects of Passwords
(2018-01-19)Despite many weaknesses, passwords are still mainly used, and will continue to be used in the near future, for the user authentication process. Passwords remain one of the important pillars of the protection structure even ... -
