Determining the impact of carrion decomposition on soil microbial activity levels and community composition.
(2013-12-01)The ubiquitous nature of microorganisms and their specificity to certain locations make them potentially useful for forensic investigators. Advances in microbial profiling techniques have made it possible to compare microbial ... -
Developing an elevated temperature Pourbaix diagram for zirconium and multi-element Pourbaix diagram of Zircaloy-4
(2023-08-01)Zirconium and Zircaloy-4 are used in applications that require corrosion resistance under extreme conditions. For example, the fuel bundles in coolant systems of CANDU™ reactors operate between 533 to 583K (260 to 310 °C). ... -
Developing effective virtual simulations and serious games: the effect of background sound cues on visual quality perception
(2012-08-01)Virtual simulations and serious games (video game-based technologies applied to teaching and learning) have been incorporated in the teaching and training curricula of a large number of professions including medicine/surgery. ... -
Development and characterization of chemical modifications for siRNA strand selection
(2021-12-01)Small interfering RNA (siRNA) are non-coding, double-stranded RNA that enable efficient gene silencing through RNA interference (RNAi) mechanisms. The primary effector of RNAi is an RNA-guided nuclease, Ago2, which selects ... -
Development and comparison of augmented and virtual reality interactions for direct ophthalmoscopy
(2020-10-01)Direct ophthalmoscopy is a medical procedure whereby a health professional examines the back of the eye, searching for life-threatening risks. The direct ophthalmoscope is used for examining the patient and it requires ... -
Development and user experience assessment of a VR resource for lactation latching
(2023-12-01)Breastfeeding is essential for infants and mothers. However, low breastfeeding rates have become a major health problem despite the use of electronic health resources used in videos, websites, and online video calls that ... -
The development of an anesthesia crisis scenario builder for virtual reality training
(2019-08-01)Anesthesiologists are trained in the field of anesthesia and preoperative medicine; they are required to develop anesthetic plans and monitor patients vitals. Currently, anesthesia trainees are taught using traditional ... -
Development of Non-covalent Chemical Probes for μ, δ and κ Opioid Receptors
(2020-12-01)Opioids are well-known pain relievers and one of several therapeutic options for pain management. Although opioids are very effective analgesics, continued use and abuse can lead to physical dependence and withdrawal ... -
Development of upper limb customized non- isomorphic VR interact ions for reaching, grabbing, and placing objects
(2022-08-01)Virtual Reality (VR) is becoming adopted in education, training, and entertainment due to its growing affordability. The variability of user preferences and physical capabilities in VR requires configurable settings in ... -
Diffusion in inhomogenous media
(2009-10-30)This project considers the diffusion of water molecules through a cellular medium in which the cells are modeled by square compartments placed symmetrically in a square domain. We assume the diffusion process is governed ... -
Direct Brønsted acid-catalyzed functionalization of benzhydryl alcohols and 2-ethoxytetrahydrofuran using potassium trifluoroborate salts
(2016-06-01)Metal-free transformations of organotrifluoroborates are advantageous since they avoid using frequently expensive and sensitive transition metals. Lewis acid-catalyzed reactions involving organotrifluoroborates have emerged ... -
Discovery of trend dependencies over time-series
(2023-11-01)We improve constraint-based data quality using trend dependency (TD) discovery, extending existing order dependencies (ODs) to allow variations and exceptions. Unlike ODs, TDs capture approximate functional mappings between ... -
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 ... -
DL-based defense against polymorphic network attacks
(2024-01-01)Network security is of vital importance in our world dominated by internet systems. These systems are vulnerable to large-scale rapidly evolving attacks by sophisticated cyber attackers who can have an upper edge over the ... -
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 ... -
Dynamic probabilistic network protection in large-scale failure scenarios
(2015-01-01)Large-scale failure resulting from natural disasters or intentional attacks is now considered a serious risk for communication network infrastructure. In these events, simultaneous damages in several links and nodes may ... -
Dynamic square patterns in two dimensional neural fields
(2015-07-29)The goal of this thesis is to study the emergence of spatiotemporal waves in neural field models. Neural field models aim to describe the activity of populations of neurons at a mesoscopic scale, considering averaged ... -
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 ... -
