Discrete optimization of upgrade scheduling
(2022-08-01)A primary objective of the mission to meet climate change goals of reducing greenhouse gas (GHG) emissions is to transition from fossil fuels to zero-emission energy. Fossil fuel production and transportation account for ... -
DistGALO: Distributed system for query problem determination
(2019-12-01)Query optimization is a quintessential element of modern Database Management Systems(DBMSs). Compile-time driven estimates and heuristics aid the compiler in selecting what is deemed the lowest cost Access Plan for a given ... -
Distributed policy-based management framework for wireless sensor networks.
(2014-06-01)Policy-Based Management Systems (PBMS) are becoming a critical component of any information technology environment, due to their ability to abstract hardware complexity from their users. Policy-based systems exist in such ... -
Do extroverts create stronger passwords?
(2018-04-01)We investigate the relationship between personality types and the strength of created and selected passwords. For this purpose, we conducted an experiment on Amazon’s Mechanical Turk, with 510 participants. Participants ... -
Do university students who experience food insecurity report psychological distress?
(2018-08-01)Introduction: Poor mental health is a substantial problem for university students and universities. Little is understood about the association between food insecurity and psychological distress in this population. Purposes: ... -
Does mental context reinstatement mitigate Retrieval Induced Forgetting in eyewitnesses?
(2020-08-01)The current study sought to examine Retrieval Induced Forgetting (RIF) as it may occur within an investigative setting, while also assessing Mental Context Reinstatement (MCR) as a tool to mitigate this forgetting. Various ... -
Dosimetric characterization of a miniature x-ray source for biophysics studies
(2015-07-01)Tritium is a low energy beta emitter that is found in abundance at CANDU nuclear power plants and is a cause of concern since it accounts for roughly thirty three percent of the total occupational exposure of nuclear ... -
