Computational study of the rovibrational spectrum of CO2–N2
(Royal Society of Chemistry, 2020-09-17)The CO2–N2 complex is formed from two key components of Earth's atmosphere, and as such, has received some attention from both experimental and theoretical studies. On the theory side, a potential energy surface (PES) based ... -
Deep Reinforcement Learning for Packaging Optimization
Packing, packaging, and layout optimization is required for efficient systems design within a wide range of industries. The increasing demand for lighter, smaller, and more efficient designs to be rapidly produced has ... -
Impact of Land Cover Change on Surface Water Temperature from 1985-2020 in Eastern Ontario
Land Cover Change (LCC) has been shown to significantly impact the magnitude and trend of Land Surface Temperature (LST), locally where it occurs. Waterbodies serve as local climate moderators where nearby LCC has the ... -
Security by Design: Reducing Information Exchange in Multi-Agent Search Tasks
Intrinsic to multi-agent systems is the trait of inter-agent dependency on information exchange. During safety-critical tasks, errors in information exchange between agents can lead to vulnerable system behaviour. Consequently, ... -
Using collocation to study the vibrational dynamics of molecules
(Elsevier, 2021-03-05)In this paper, I review collocation methods for solving the time-independent and the time-dependent Schroedinger equation. Unlike traditional variational methods, collocation methods do not require integrals and quadrature. ... -
Neoliberal Pressures, Neoliberal Responses: The Strategic Utilization of Gender in the Canadian Settlement Sector and Implications for Immigrant Women’s Service Organizations
This dissertation examines the effects of neoliberalism within immigrant women’s service organizations and the delivery of gender-specific programs in the Canadian settlement sector. The influence of neoliberalism within ... -
A variational calculation of vibrational levels of vinyl radical
(AIP Publishing, 2020-05-29)We report the vibrational energy levels of vinyl radical (VR) that are computed with a Lanczos eigensolver and a contracted basis. Many of the levels of the two previous VR variational calculations differ significantly and ... -
A collocation-based multi-configuration time-dependent Hartree method using mode combination and improved relaxation
(AIP Publishing, 2020-04-30)Although very useful, the original multi-configuration time-dependent Hartree (MCTDH) method has two weaknesses: (1) its cost scales exponentially with the number of atoms in the system; (2) the standard MCTDH implementation ... -
Population genetic differentiation and hybridization in the Glaucous Gull (Larus hyperboreus)
Climate change poses a significant threat to the future of Arctic ecosystems. To effectively conserve Arctic species, genetically differentiated populations must be defined for adaptive and neutral genetic variation to be ... -
Detection of Antibiotic Resistance in Enterococcus spp. by Growth Kinetics Measurements in the Presence of Vancomycin Using the Detection System from TECTA-PDS
The spread of antibiotic resistant organisms has increased in different water environments. This originates from the disposal of antibiotics from hospital wastes, irrigation from farms, domestic antibiotic drug disposal ... -
INVESTIGATION INTO POTENTIAL MAGMATIC CONTRIBUTIONS TO VOLCANOGENIC MASSIVE SULFIDE DEPOSITS: METHOD DEVELOPMENT FOR LA-ICP-MS ANALYSIS OF FLUID INCLUSIONS AND CRITICAL ASSESMENT OF THE WINDY CRAGGY DEPOSIT, NORTHWESTERN BRITISH COLUMBIA, CANADA
In recent years, the existence of variable magmatic contributions to the mineralizing fluids in the formation of volcanogenic massive sulfide (VMS) deposits has been gaining acceptance in the scientific community. The ... -
ANALYSIS, OPTIMIZATION, AND PRACTICAL DESIGN OF A SPLIT-PHASE DICKSON SWITCHED CAPACITOR CONVERTER FOR HIGH CURRENT APPLICATIONS
The Switched-Capacitor Converter (SCC) topology has been gaining attention from researchers because of their advantages of higher power density, better switch utilization, and low component stress. However, SCCs have a ... -
Disturbing Silence: How the Student Movement Shaped Nixon’s Presidency and the Policies of America
President Richard M. Nixon’s fear and hatred of the Students for a Democratic Society (SDS) resulted in the SDS having an undue influence on his foreign policies. The SDS was a small faction of the larger Anti-Vietnam War ... -
Interweaving Iiyiyiu (Cree) Ways of Knowing and Land-Based Learning with Science Curriculum at Waapinichikush Elementary School, Chisasibi, Quebec
This study is the result of work done in close collaboration and partnership with local Cree (Iiyiyiu) teachers, Elders and community members at Waapinichikush Elementary School in Chisasibi, Quebec, to identify approaches ... -
Beta-Band EEG Activity and False-Belief Reasoning in Adults
The ability to reason about other’s beliefs, and in particular their false beliefs, is a fundamental part of having a theory of mind (ToM) – an understanding of the role that mental states (i.e., beliefs, desires, and ... -
Childhood Maltreatment and the Association with Life Dissatisfaction
This study examined the association between childhood maltreatment (witnessing violence in the household, and experiences of physical and emotional abuse by an adult prior to the age of 16,) and dissatisfaction with later ... -
Spatial Voting Models: A Dynamical Systems Approach
Spatial voting models have been used extensively to study factors affecting candidate positioning in elections. Most previous research has fixed candidate positioning at one point in time to determine optimal candidate ... -
Investigating ubiquitin-mediated turnover of the key immune signaling protein kinase BOTRYTIS INDUCED KINASE1
Plants are susceptible to infection from bacterial, fungal, and viral diseases; although sessile, they are far from defenseless. Plants have evolved complex immune systems for the detection of pathogens and initiation of ... -
Security of Short-Range Wireless Technologies and an Authentication Protocol for IoT
The number of wireless IoT (Internet of Thing) infrastructures is considerably growing as thousands of new devices are being connected everyday. This has allowed the emergence of various smart applications that have changed ...
