Enhancing Convective Heat Transfer Over A Surrogate Photovoltaic Panel, Fama Fouladi
Electronic Theses and Dissertations
This research is particularly focused on studying heat transfer enhancement of a photovoltaic (PV) panel by putting an obstacle at the panel’s windward edge. The heat transfer enhancement is performed by disturbing the airflow over the surface and increasing the heat and momentum transfer. Different objects such as triangular, square, rectangular, and discrete rectangular ribs and partial grids were applied at the leading edge of a surrogate PV panel and flow and the heat transfer of the panel are investigated experimentally. This approach was selected to expand understanding of effect of these different objects on the flow and turbulence structures …
Travel Demand Modeling For London, Ontario, Canada, Rahaf Husein
Travel Demand Modeling For London, Ontario, Canada, Rahaf Husein
Electronic Theses and Dissertations
Travel demand modeling is one of the key areas in transportation planning and engineering. Traditionally, it has been based on four inter-connected modules: trip generation, trip distribution mode choice, and traffic assignment. While the traditional approach remains popular among practitioners, it has been criticized widely due to its zonal aggregate nature. There has been a shift towards using micro-based models that use households and members of households as the units of analysis in lieu of the traffic analysis zones. This thesis contributes to advancing this micro-based paradigm by studying travel demand in the London Census Metropolitan Area (CMA), Ontario. It …

Understanding The Absence Of Female Coaches In Sport And The Value Of Same-Sex Role Models For Female Athletes In Their Coaching Pursuits, Taylor Dawn Imeson
Electronic Theses and Dissertations
Like many leadership positions, women hold very few head coaching positions in sport. This does not mean that women are not involved in sport; in most cases, they take on smaller roles like assistant coach, trainer or executive/board positions. Previous research suggests that same-sex role models can aid in increasing the number of females that take on coaching as a career. Utilizing an online survey and focus group sessions with CIS level female athletes, the current study examined the influence of coaches, both male and female on these athletes and their desires or aspirations to coach as a career and/or …

Extending External Agent Capabilities In Healthcare Social Networks, Nima Moradianzadeh
Electronic Theses and Dissertations
A social health care system, such as palliative care, can be viewed as a social network of interacting patients and care providers. Each patient in the network has a set of capabilities to perform his or her intended daily tasks. However, some patients may not have the required capabilities to carry out their desired tasks. Consequently, different groups of care providers - consist of doctors, volunteers, nurses, etc.- offer the patients support by providing them with a variety of needed services. Assuming there are a cost and resource limitations for providing care within the system, where each care provider can …

This thesis focuses on developing such a general approach which is applied to the design of a wind tunnel meant for the University of Windsor. It is shown that, by applying the first principles of fluid mechanics to the problem, the components required, for operation of the wind tunnel within set constraints and requirements are identified. Numerical simulations are performed in two parts: 1) two-dimensional computational fluid dynamics simulations, which enable …
Population And Family Effects On Gene Transcriptional Profiles Of Eight Hybrid Chinook Salmon (Oncorhynchus Tshawytscha) Populations: Implications For Conservation And Aquaculture, Shelby Toews
Electronic Theses and Dissertations
Aquaculture has been the fastest growing food industry worldwide since 1985 and has contributed significantly to the Canadian economy. Thus, methods for increasing aquaculture production are currently being investigated, such as selective breeding programs. Here I developed transcriptional profiles of eight hybrid half-sibling populations of Chinook salmon (Oncorhynchus tshawytscha) and examined them for evidence of local adaptation and as a potential marker for marker-assisted selection method. I found evidence of local adaptation among the populations, further supporting this as a driving force behind the large variation witnessed in Chinook salmon life history variation. I used the transcriptional profiles developed for …
Testing The Robustness Of The Circadian Clock, Nathaniel James Bernardon
Testing The Robustness Of The Circadian Clock, Nathaniel James Bernardon
Electronic Theses and Dissertations
The surface of the Earth receives 24 hour cycles of light and darkness. Most living things have arisen under these conditions, and have evolved circadian clocks to keep track of time. In Drosophila, the circadian clock comprises the genes Clock (CLK) and Cycle (CYC) which are negatively regulated by the genes Period (PER) and Timeless (TIM). CLK/CYC are transcription factors: their targets include PER/TIM, which accumulate as proteins to repress their own production. Light deactivates PER/TIM proteins, periodically activating CLK/CYC, and causing 24h rhythms of transcription activity. Our lab has previously shown that intestinal stem cells are regulated by the …

Structures From Distances In Two And Three Dimensions Using Stochastic Proximity Embedding, Udayamoorthy Navaneetha Krishnan
Electronic Theses and Dissertations
The point placement problem is to determine the locations of a set of distinct points uniquely (up to translation and reflection) by making the fewest possible pairwise distance queries of an adversary. Deterministic and randomized algorithms are available if distances are known exactly. In this thesis, we discuss a 1-round algorithm for approximate point placement in the plane in an adversarial model. The distance query graph presented to the adversary is chordal. The remaining distances are uniquely determined using the Stochastic Proximity Embedding (SPE) method due to Agrafiotis, and the layout of the points is also generated from SPE. We …

The Online Culture Of Cyberbullying: Examining The Cycle Of Subcultures Through Media Constructions Of Cyberbullying As A Deviant Youth Internet Phenomenon, Molly-Gloria Rachelle Harper
The Online Culture Of Cyberbullying: Examining The Cycle Of Subcultures Through Media Constructions Of Cyberbullying As A Deviant Youth Internet Phenomenon, Molly-Gloria Rachelle Harper
Electronic Theses and Dissertations
Youth culture today is based on the number of ‘likes’, ‘shares’, ‘retweets’, and ‘followers’ a person has on various social media sites. Reliance on technological devices, Internet connections, and a cyber presence has produced a generation where traditional face-to-face bullying has become more complex. Using the theoretical framework of cultural criminology, this paper illustrates the cultural construction of cyberbullying as a phenomenon, which emerged from the broader youth culture’s reliance on ‘being connected’, and designs the subcultures within as working in a cyclical fashion with one another to define and understand cyberbullying. Subcultures are characteristics of the entire umbrella of …

Relationships Between Children’S Use Of Imagery And Domains Of Physical Competence, Jesse Martin
Relationships Between Children’S Use Of Imagery And Domains Of Physical Competence, Jesse Martin
Electronic Theses and Dissertations
Low levels of perceived motor and physical competence are viewed as barriers to physical activity in children (Weiss, 2000). Imagery is an effective psychological skill that can create feelings of competence in those who use it (Weinberg, 2008). As such, imagery may be one way to enhance perceptions of competence and increase physical activity participation. The overall purpose of the present study was to examine the relationship between children’s use of active play imagery (fun, capability, and social imagery) and the domains of physical competence (global self-worth, physical self-worth, sport competence, body attractiveness, physical strength, and physical conditioning). Male (n …
Design Of An Adaptable Tooling System For Part To Part Variation Processing, Boris Novakovic
Design Of An Adaptable Tooling System For Part To Part Variation Processing, Boris Novakovic
Electronic Theses and Dissertations
Today’s automotive manufacturing facilities use different robotic systems with the specifically designed end of arm tooling (EOAT). Regardless of how accurate these robotic systems may be, they are programmed to repeat the same task and move to the same position repeatedly. As convenient as this process may be, it does not allow robots to automatically readjust to different part variations without the human assistance. This situation is especially noticeable in the plastics manufacturing industry, e.g., fuel tank welding. This thesis describes the systematic design methodology of an adaptable tooling system for a part to part variations processing aimed at automotive …
Knowledge Migration Strategies For Optimization Of Multi-Population Cultural Algorithm, Panth Parikh
Knowledge Migration Strategies For Optimization Of Multi-Population Cultural Algorithm, Panth Parikh
Electronic Theses and Dissertations
Evolutionary Algorithms (EAs) are meta-heuristic algorithms used for optimization of complex problems. Cultural Algorithm (CA) is one of the EA which incorporates knowledge for optimization. CA with multiple population spaces each incorporating culture and genetic evolution to obtain better solutions are known as Multi-Population Cultural Algorithm (MPCA). MPCA allows to introduce a diversity of knowledge in a dynamic and heterogeneous environment. In an MPCA each population represents a solution space. An individual belonging to a given population could migrate from one population to another for the purpose of introducing new knowledge that influences other individuals in the population. In this …

Returning Year After Year: The Motivation And Retention Of Coaches At Madawaska Volleyball Camp, Jennifer Straver
Electronic Theses and Dissertations
As the popularity of attending summer camps continues to rise, it is important that Camp Directors understand what motivates employees to choose to work at camp each summer. In this study, I implemented a qualitative approach using interpretive phenomenological analysis (IPA) to examine the motivational factors that keep coaches at Madawaska Volleyball Camp (MVC) coming back each summer. Eight participants shared their unique experiences at Madwaska Volleyball Camp (MVC) through semi-structured interviews. Four themes emerged that solidified their motivations to return to work at camp each year: alignment, tradition, opportunities for reflection and personal growth, and the surrounding environment.
The Acute Physiological Responses To Leg Extension Resistance Training Using Drop Sets Versus Standard Hypertrophy Training In The Quadriceps Femoris, Alex Waugh
Electronic Theses and Dissertations
Resistance training (RT) for muscle growth (hypertrophy training – HT) theoretically optimizes the mechanical tension and time under tension (TUT) placed on working muscle, which may be key to activating hypertrophic mechanisms. After prolonged HT, specialized weightlifting techniques like drop set training (DS) – or lifting progressively reduced loads without recovery – may help overcome plateaus in strength and re-stimulate hypertrophy, but evidence for the efficacy of acute DS compared to HT is limited. This thesis compared acute anabolic, metabolic, and intensity responses between DS and HT in the quadriceps femoris using leg extensions. Thirty young males completed, in a …
