    Implementation of Convolutional Neural Networks for Warp Detection in 3D Printed Components manufactured via Fused Filament Fabrication: A Bayesian-Based Automated Approach
    Implementation of Convolutional Neural Networks for Warp Detection in 3D Printed Components manufactured via Fused Filament Fabrication: A Bayesian-Based Automated Approach
    Fused Filament Fabrication (FFF) is an additive manufacturing technique commonly used in industry to produce complicated structures sustainably. Although promising, the technology frequently suffers from defects, including warp deformation compromising the structural integrity of the component and, in extreme cases, the printer itself. To avoid the adverse effects of warp deformation, this thesis explores the implementation of deep neural networks to form a closed-loop in-process monitoring architecture using Convolutional Neural Networks (CNN) capable of pausing a printer once a warp is detected. Any neural network, including CNNs, depend on their hyperparameters. Hyperparameters can either be optimized using a manual or an automated approach. A manual approach, although easier to program, is often time-consuming, inaccurate and computationally inefficient, necessitating an automated approach. To evaluate this statement, classification models were optimized through both approaches and tested in a laboratory scaled manufacturing environment. The automated approach utilized a Bayesianbased optimizer yielding a mean accuracy of 100% significantly higher than 36% achieved by the other approach.
    Indigenous city field trip a resource guide to Ryerson University
    Indigenous city field trip a resource guide to Ryerson University
    This resource guide contributes to a knowledge base of events, facts, interpretations, and relationships relating to Indigenous peoples with a particular focus on the land that is currently occupied by Ryerson University. This knowledge base is available for free to anyone who wishes to learn about or educate others about this topic. We realize that nobody “owns” this knowledge but that knowledge is always embodied and situated in personal experiences. Please use and share this knowledge responsibly and with respect. The guide is intended to facilitate walking field trips involving particular sites (i.e. “stations”) located on or close to Ryerson campus. For each station, we identified several resources and included links to original sources. We structured this guide by listing the sources followed by a brief description of the information from the source in bullet form. This brief description does not replace reading the original source but is rather intended to help the reader navigate the guide. We envision several ways in which this guide can be used: it can be used as a self-guided tour; it can be used by the community organizations and Ryerson instructors to develop field trips to be delivered to their classes or other audiences; or it can be used by students and the wider community to learn about Indigenous peoples and their relationship to Ryerson University., Caribou, J., Reesor, R., & Ryerson University.

    Pass the mic: women finding space on air
    This is a compilation of interview with various women who work or have worked in the radio industry primarily in Toronto, Canada. The interviews were conducted as part of a research project which seeks to collect information about women's experiences of an d perceptions about working in radio - an industry which, like all media industries, has traditionally been male dominated., Beckstead, L.

    Prevalence and characerization of plasmid-mediated quinolone resistance in various aquatic sources
    Ciprofloxacin is a fully synthetic antibiotic developed in 1987 and remains among the most widely used antibiotics worldwide Excessive usage has resulted in small quinolone concentrations found in aquatic sources Environments with subinhibitory antibiotic concentrations and high microbial diversity and nutrient loads (e g wastewater) foster the development of antibiotic resistance genes qnr genes conferring quinolone resistance were first found in 1998 and have since been observed on a global scale, Yusuf, F., Ing, R.

    Prospects of CRISPR/Cas cloning vectors to combat antibiotic resistance gene dissemination
    Prospects of CRISPR/Cas cloning vectors to combat antibiotic resistance gene dissemination
    CRISPR (Clustered Regularly Interspaced Small Palindromic Repeats) and Cas (CRISPR associated) proteins comprise an adaptive immune system in prokaryotes CRISPR Cas systems digest invading nucleic acids and incorporate a 30 bp snippet (“spacer") of the invader into the host genome Spacers are transcribed into CRISPR RNAs (crRNA's) that recognize the same nucleic acid in the event of a repeat invasion and guide nucleases to the target for elimination We hypothesize that a plasmid vector, when transformed into a host cell, could exogenously express a CRISPR/Cas system and prevent the host’s participation in conjugative processes, Ing, R., Gilbride, K.

    Qualitative assessment of worker productivity and experience in office environments
    Qualitative assessment of worker productivity and experience in office environments
    This project is a study on the building impact of occupant’s productivity and well being in an office environment. Presented through an office case study, the work takes part of a larger pre- and post-move study carried out over the course of a year. The study collects, analyses, and compares numerous sources of data in a pre- and post-move study: 1) environmental data using desk sensors 2) online qualitative surveys of user comfort relative to location in the office 3) an architectural assessment of the spaces in the office. The collection of both pre- and post-move data is intended to allow findings to be compared to understand the impacts of environmental design on worker productivity and building performance and address the challenges in conducting successful pre- and post-move assessments., Cepic, M.

    RBS moment connection analysis using a solid model
    RBS moment connection analysis using a solid model
    The unpredictability of the steel beam welding connection has led to many solutions, including the are of focus for this research Reduced Beam Section ( Moment Connections The RBS in steel moment connection facilitates the calculation and predictability of failure in design The RBS section is created by cutting out part of the flanges in a beam This creates a plastic hinge where the beam will fail first 1 This creates a model of predictability on the durability and strength of the beams Creating a RBS connection increases the overall ductility of the steel frame The RBS section reduces the flange width which causes stress concentration on the reduced section and this then lowers the stress on the welds. The lower stress then prevents unexpected brittle fracture in the welding a predicted plastic deformation of the RBS section during a seismic event 2 3 The research is focused on optimizing the RBS connection Finite models will be created using ANSYS to investigate how different RBS connections react in different situations and what is the most efficient design in terms of safety and cost., Coello-Mena, M.

    Revealing the voices of women living with IBD
    Revealing the voices of women living with IBD
    The purpose of this exploratory study is to center the voices of women who are living with inflammatory bowel disease (IBD) in order to understand their lived experiences and the kinds of support and resources they most value. Our review of the literature has indicated that studies which reveal the personal, lived, qualitative experiences with women with IBD are scarce. Instead, the existing body of research tends to be highly medicalized and expert-driven. In this study we constructed a sample of 20 YouTube videos posted by women living with Crohn's Disease and Ulcerative Colitis, who openly shared their experiences of living with the disease. Using phenomenology, coupled with an intersectional lens, we explored how living with IBD, was informed by gender, race, class and age. We hope to publish this exploratory work as a way to begin to address the gap in our understanding of the lived experiences with IBD., Sebastian, S., Perreault-Laird, J., Silver, S. (October, 2019).
