Towards implicit learning of system-assigned authentication tokens
(2018-02-01)People tend to choose predictable passwords which are vulnerable to guessing attacks. To combat the security issue, system-assigned authentication keys were proposed, but coming at a cost to memorability. In this thesis, ... -
Cognitive function during exertional heat stress assessed using traditional and serious game technology
(2016-06-01)Firefighting is a physically demanding occupation requiring intermittent bouts of work resulting in increased levels of cardiovascular and thermal strain, while making decisions requiring higher order cognitive abilities ... -
Mechanisms by which exercise promotes cognitive function in both depressed and non-depressed individuals
(2017-12-01)Major depressive disorder (MDD) is a debilitating disease characterized by low mood, memory deficits, poor sleep quality and alterations in biochemical markers associated with neuroplasticity. Less than half of MDD patients ... -
Secure and privacy-preserving fog-assisted vehicular crowdsensing
(2018-08-01)Vehicular crowdsensing (VCS) is an emerging paradigm where vehicles use onboard sensors to collect and share data with the aim of measuring phenomena of common interest. VCS has allowed for automated control as well as ... -
The ecotoxicological effects of metformin and its metabolite, guanylurea, on Japanese medaka (Oryzias latipes)
(2018-08-01)Human pharmaceutical waste threatens many natural processes of non-target aquatic organisms, through the introduction of such contaminants into the environment. Pharmaceuticals are a large and diverse groups of medicinal ... -
Towards efficient and scalable computer vision systems
(2018-01-01)There is a large growth in hardware and software systems capable of producing vast amounts of image and video data. These systems are rich sources of continuous and possibly infinite image and video streams. This motivates ... -
A secure and privacy-preserving incentive framework for vehicular cloud
(2018-04-01)Vehicular Cloud Computing (VCC) plays a critical role in data generation where a large number of vehicles collect various kinds of sensing resources with large-volume features. While the information that should be collected ... -
The impact of restricted ration and chemical stressors on Rainbow trout (Oncorhynchus mykiss) and American flagfish (Jordanella floridae)
(2017-12-01)This research aimed to increase the understanding of the impact of multiple factors including both environmental and chemical stressors and their effects on fish survival, growth, and reproduction. Rainbow trout (Oncorhynchus ... -
Adaptive engagement of older adults’ fitness through gamification
(2017-07-01)Older adults are often not physically active because they lack motivation, time, and/or physical ability. Not only does this impact the life of older adults, but it also affects society as a whole, because the cost of ... -
Community-oriented architecture for smart cities
(2017-12-01)With the widespread use of smartphone devices, a surge in mobile sensing, progress in wireless communication and networking techniques, as well as the development of the Internet of Things (IoT) and cloud computing, ... -
Examining swim bladder inflation failure as a toxicological endpoint in Japanese medaka (Oryzias latipes)
(2017-11-01)Inadequate swim bladder inflation, while not being lethal itself, can have serious long-term effects on fish populations. Many environmental contaminants can inhibit swim bladder inflation of larval fish. Understanding how ... -
The effect of experimental pain on neural function and motor learning
(2017-04-01)This thesis investigated whether acute experimental pain interacts with motor learning acquisition to create adaptive and maladaptive changes in neural function. The first study consisted of two experiments where we ... -
Nanostructured materials for photovoltaics and microwave electronics: methods and applications
(2017-04-01)Nanoscale particles and thin layers are today used for a variety of applications to make industrial products lighter, stronger or more conductive. This study investigates synthesis, characterization and application of ... -
Synthesis and characterization of Pt/TiO2/C composite catalysts for fuel cells prepared using a glucose modifier
(2017-03-01)Catalysts in the electrodes of polymer exchange membrane fuel cells (PEMFCs) serve a critical function in reactions which can be used to generate electrical energy from chemical fuels. Pt nanoparticles are commonly dispersed ... -
Influence of dietary interventions on the immune system: an investigation of the impact of omega-3 fatty acids, dietary fermentable materials and high energy diets
(2016-12-01)Dietary interventions vary in ability to influence immune activity. Separate investigations were conducted to determine the immune impact of omega-3 fatty acids, dietary fermentable materials (DFM) and high energy (HE) ... -
A framework for privacy-preserving data sharing in smart grid
(2016-01-01)While smart grid introduces a lot of enhancements to the traditional power grid and improves managing and controlling consumers demands, it also introduces security and privacy issues. Therefore, failure to address them ... -
A dynamic visual analytics framework for complex temporal environments
(2016-08-01)Introduction: Data streams are produced by sensors that sample an external system at a periodic interval. As the cost of developing sensors continues to fall, an increasing number of data stream acquisition systems have ... -
Alloy catalysts for fuel cell-based alcohol sensors
(2016-05-01)Direct ethanol fuel cells (DEFCs) are attractive from both economic and environmental standpoints for generating renewable energy and powering vehicles and portable electronic devices. The cost and performance of the DEFCs ... -
