Identity development, attraction, and behaviour of heterosexually identified men who have sex with men: scoping review protocol
No full textAbstract
Background Heterosexually identified men who have sex with men (H-MSM) are distinct from other hetero-
sexual men and from gay, bisexual, and other sexual minority men. Specifically, H-MSM experience discordance
between their sexual identity (i.e., heterosexual) and behaviours (i.e., sexual encounters with other men). This sexual
identity-behaviour discordance can create barriers to obtaining healthcare and social support. Understanding
and accepting H-MSM as they self-identify may be necessary to implement effective public health and psychosocial
interventions. The aim of the present study is to provide an overview of research on H-MSM.
Methods A scoping review will be conducted to identify and describe the identity development, attraction,
and behaviour of H-MSM. This scoping review will also identify and describe current trends related to the recruitment
of H-MSM and recommend directions for future research. Searches will be conducted in Academic Search Complete,
APA PsychInfo, CINAHL Plus with full text, Education Research Complete, Gender Studies Database, GenderWatch,
Health Source: Nursing/Academic Edition, LGBTQ + Source, MEDLINE, Psychology and Behavioral Sciences Collec-
tion, SocINDEX with full text, Sociological Collection, Social Work Abstracts, ProQuest Dissertations and Theses,
and ResearchGate. Primary research studies published in peer-reviewed journals will be included. Dissertations
and theses that include primary research on H-MSM will also be included. Reference lists, experts in the field, pre-
print servers, and relevant conferences will also be consulted for extant and in-progress literature. Two reviewers
will independently pilot the data extraction form and conduct the title and abstract screening, with consultation
from a research librarian. Seven reviewers will then conduct the full-text article screening. Thematic content analysis
will guide the review; through independent review and reviewer meetings, themes and subthemes will be identified
and reported from the extracted literature.
Discussion This is the first known knowledge synthesis on H-MSM, seeking to better understand sexual identity-
behaviour discordance amongst cisgender men. We anticipate that a theoretical framework of H-MSM’s sexuality,
internal processes, and behaviours will be constructed from this review. Alongside implications for further research
with H-MSM, this review may be relevant to sexually transmitted infection public health and to clinicians working
in the field of male sexuality.Insight Grant, Social Sciences and Humanities Research Council (SSHRC

Enhancing temperature control in greenhouses: A comparative anaylsis of TRNSYS simulation and real time data
No full textA Thesis Submitted to the Faculty of Graduate Studies and Research In Partial Fulfillment of the Requirements for the Degree of Master of Applied Science in Electronic Systems Engineering, University of Regina. xvi, 123 p.Accurately reproducing humidity and temperature information is highly important in a range of fields, such as architecture, energy conservation, environmental analysis and climate change research. Software tools like TRNSYS 18 have become invaluable in modeling and predicting conditions. These technologies provide cost efficient alternatives to practical experimentation. However, it remains crucial to verify simulation results by comparing them with real time measurements to ensure the reliability and authenticity of the software.
This thesis presents a validation methodology for the TRNSYS model 18 program focusing specifically on assessing its capabilities in simulating humidity and temperature. The study aims to establish an approach for evaluating the accuracy of TRNSYS 18 by comparing its outputs with real time data collected from various environmental monitoring systems in a small greenhouse. And this study also tries to identify and verify the transfer function of a small greenhouse based on which the internal temperature of the greenhouse changes. By bridging the gap between simulation and reality this research offers researchers and practitioners a valuable simulation strategy for designing and managing a greenhouse.
The validation process involves aspects, including data collection, instrumentation and measurement methods used to obtain real time humidity and temperature data. The analysis encompasses an examination of both simulated results, from TRNSYS 18 and corresponding real time measurements.
This analysis aims to identify and explain similarities and differences well as potential factors that could contribute to any inconsistencies observed. In addition, the thesis examines the constraints of the application and identifies alternative avenues for enhancement, thereby providing significant perspectives for software engineers and academics.
This thesis makes a substantial addition to the subject of simulation validation, with a specific emphasis on evaluating the humidity and temperature functionalities of the TRNSYS 18 program and MATLAB identification tool.
By addressing the vital aspect of software reliability and control system implementation, this work facilitates more accurate predictions, empowers users to make informed decisions, and enables the effective utilization of TRNSYS 18 in various applications where temperature and humidity simulations, as well as precise control are essential.

Implementation of spiking neural network on field-programmable gate array for image classification
No full textA Thesis Submitted to the Faculty of Graduate Studies and Research In Partial Fulfillment of the Requirements for the Degree of Master of Applied Science in Electronic Systems Engineering, University of Regina. xv, 99 p.This thesis concerns the Spiking Neural Network (SNN) implementation on a Field-Programmable Gate Array (FPGA). SNN is a particular Artificial Neural Networks (ANN) form. An SNN has similar features as an ANN, but an SNN has a different information system that will allow SNN to have higher energy efficiency than an ANN. This thesis aims to design an SNN with low accuracy loss and high power efficiency that can be easily implemented on an FPGA. The theory of ANN, the coding schemes of SNN, the training methods of SNN and the implementation methods of SNN on FPGA are investigated in this thesis. The theory of ANN in this thesis focuses on activation functions and neural network architectures for high accuracy. The coding scheme of SNN is investigated to get high accuracy and low power consumption. The training method of SNN is presented to be with low accuracy loss. The implementation methods of SNN on FPGA are compared in this thesis for high power efficiency. As a result, The FPGA-based SNN model is designed to be lower power consumption than existing SNN models in the aspect of FPGA implementation and lower accuracy loss than the current training method in the part of the algorithm. The coding scheme of the SNN model proposed in this thesis is the rate coding scheme. This thesis introduces a conversion method that directly maps the trained parameters from ANN to SNN with negligible classification accuracy loss. Also, this thesis demonstrates the technique of FPGA implementation for the Spiking Exponential Function, Spiking SoftMax Function and Dynamic Adder Tree. This thesis also presents the Time Division Component Reuse technic for lower resource utilization in the FPGA implementation of SNN. The SNN model has a high power efficiency of 0.0192 micro-joules ( ) per synapse while processing 10000 MNIST images per second. With an adjustable processing speed, the SNN model could reach a high power efficiency of 0.00159 per synapse per image, and the accuracy loss is 1.1 percent.Studentye
Ensemble-based framework and its applications to characterizing growth and propagation dynamics of wormhole networks and steam chambers in a heavy oil reservoir
No full textA Thesis Submitted to the Faculty of Graduate Studies and Research In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy in Petroleum Systems Engineering, University of Regina. xxix, 273 p.As for the enormous heavy oil resources all over the world, cold heavy oil production with sand (CHOPS) technique has been successfully utilized to exploit them as the primary recovery due to the induced high-permeability channels (i.e., wormholes) together with foamy oil flow, while the steam-assisted gravity drainage (SAGD) process has been widely used as an efficient enhanced oil recovery (EOR) method because of the steam chamber propagation together with viscosity reduction and gravity drainage. Numerous efforts have been made to characterize the growth and propagation dynamics of wormhole networks and steam chambers; however, it is still a challenging task to reproduce the experimental measurements and field observations due to the physical constraints and strong nonlinearity. Therefore, it is of fundamental and practical significance to develop robust and versatile techniques for characterizing the growth and propagation dynamics of wormhole networks in a CHOPS process and a steam chamber in a SAGD process, respectively.
A modified pressure-gradient-based (PGB) sand failure criterion has been developed for quantifying the dynamical and preferential wormhole propagation during a CHOPS process. By upscaling it from pore-scale to grid-scale, such a sand failure criterion is successfully validated with a laboratory experiment and then extended to a field case. Subsequently, a damped iterative-ensemble-Kalman-filter (IEnKF) technique has been developed for dynamically and implicitly determining the model uncertainties during a CHOPS simulation, while an improved upscaling process has been proposed to improve the versatility and accuracy of the PGB sand failure criterion. Not only does such an ensemble-based data assimilating algorithm demonstrate a satisfactory convergence, but also the simulated wormhole network shows its great similarity to the experimental observation. Moreover, the impacts of foamy oil flow, sand failure, and slurry flow are comprehensively evaluated by employing various sets of multiphase relative permeability for the simulation. By integrating the modified PGB sand failure criterion, foamy oil model, multiphase relative permeability model, and damped-IEnKF algorithm into a reservoir simulator (i.e., CMG STARS), a unified, efficient, and consistent ensemble-based framework has been established to characterize the field-scale wormhole growth and propagation dynamics with good accuracy and efficiency, demonstrating its practicality and robustness in simulating the CHOPS processes in heavy oil reservoirs.
A heat-penetration criterion has then been newly developed and integrated into a reservoir simulator (i.e., CMG STARS) for characterizing the steam chamber growth and propagation dynamics during a SAGD process, while thermally sensitive co/countercurrent relative permeabilities are incorporated in the simulation. Temperature distribution ahead of a steam chamber interface (SCI) is dynamically calibrated by such a heatpenetration criterion, providing a simple and convenient way to pragmatically, dynamically, and accurately quantify heat transfer during a SAGD simulation.Studentye
How judges define intimate partner violence
No full textA Thesis Submitted in Partial Fulfillment of the Requirements for the Degree of Bachelor of Arts (Honours) in Psychology, University of Regina. 49 p.Due to its widespread prevalence, the World Health Organization (2021) declared Intimate Partner Violence (IPV) as a major public health problem. In Canada, there is no legal definition, or charge that exists in the Canadian Criminal Code (CCC). The purpose of this study is to: (1) examine how judges in criminal cases define IPV in the prairie provinces (i.e., AB, SK, and MB); and (2) determine if IPV definitions are influenced by verdict decisions (i.e., guilty vs. innocent). Full-text, written judicial decisions from 71 sentencing, 17 trial, and 12 pre-trial or voir dire hearings (N = 100; years 2016-2022) were obtained and coded for several different themes. Results revealed that judges tend to discuss IPV as it relates to physical violence (e.g., assault), psychological abuse, and intimidation (e.g., uttering threats) as elements of IPV. Given that current Canadian law does not recognize psychological abuse as a criminal offence, this may signal a need to create a legal definition of IPV to more directly align with how it is being discussed in courtrooms.Studentn
Archer Library Award 2023 - Reflective Essay
No full textThe Fall 2022 semester started my second year as an English Honours student at the University of Regina. Each 200-level course I chose came with various new challenges compared to the previous year. One crucial challenge I experienced was finding scholarly sources for my english, politics, and criminology research papers. At the beginning of the fall semester, I needed to learn how to search for specific topics appropriately, and I was unaware of the different databases for each subject. However, I decided to make an appointment with a librarian to see if they would be able to point me in the right direction when it came to using the library’s resources. The librarian was extremely helpful and showed me two specific databases that provided scholarly articles in politics and criminology. Because of his help, I found scholarly sources for my upcoming English research paper on “Lanval” by Marie de France.Facultyye
Computation of inverse kinematics of redundant manipulator using particle swarm optimization algorithm and its combination with artificial neural networks
No full textA Thesis Submitted to the Faculty of Graduate Studies and Research In Partial Fulfillment of the Requirements for the Degree of Master of Applied Science in Industrial Systems Engineering, University of Regina. xiv, 95 p.Nowadays, the world of the industry is not working without the robotics’ manipulators. Logically, robotic manipulators are very old topics and lots of researches have been done on them. However, with implementing recent methodologies on them, many contributions have been achieved, which even become a part of human’s life.
The objective of this research is to achieve more precise position for end effector of rescue robotic manipulator in real time within reasonable calculation time. In this regard, all the inverse kinematics formulation of the 2, 3, and 4-links manipulator are derived, and be solved by Particle Swarm Optimization (PSO) method. It should be mentioned that this optimization method will be used to solve the inverse kinematics problem in real-time mode which consequently making the results more accurate. The presented PSO method is implemented on a rigid 3-link manipulator with three rigid revolute joints. It is pointed out that the application of the robot manipulator in this paper is used as a rescue robot for the first time, which has stronger environmental adaptability and real-time performance.
It is shown in this study, the precision of PSO method is about 10-3.6 (0.0002511) within 50 iterations which is a lot better than previous research (i.e. an ANN application did the same study and used the same platform only can generate a result with the error of 0.045589 in 1000 epochs). However, as the PSO method is real-time, the presented PSO method will consume a lot more time than the other methods such as ANNs. For instance, the PSO method took 2 minutes and 10 seconds to solve an inverse kinematics problem comparing with 36.10 seconds that solved by an ANNs. Therefore, author developed a combination approach that mixing the PSO method and ANN technique, namely PSO-ANN, to solve rescue robotic manipulator in real time, which can generate high accuracy results in a short testing time. Due to the aforementioned description, the contribution of this study is to reach to more precise methodology with less error due to the previous studies and also presenting the methodology that can solve all the issues in regards of the run-time of the real-time methods.Studentye
