Authors: Tagliabue Semira
Published: June 2021

Il presente contributo analizza il contributo vicendevole della psicologia della liberazione e della prassi scientifica attuale. Nello specifico sono affrontate, innanzitutto, le questioni epistemologiche, legate alla necessitŕ di una scelta esplicita in tal senso, cosě pure alla legittimitŕ delle diverse epistemologie presenti in ambito psicologico. Sono poi trattati diversi aspetti di metodo, sottolineando l'importanza di opzioni metodologiche complesse. Infine, viene affrontato l'aspetto dell'etica, non considerata solo come prospettiva individuale, ma anche comunitaria e liberante. Nelle conclusioni si sottolinea la rilevanza di un approccio critico e complesso in psicologia.
Psicologia della liberazione e psicologia critica di comunitŕ come conquista di felicita, libertŕ ed equitŕ
Authors: Arcidiacono Caterina , Di Martino Salvatore
Published: June 2021

Il testo parte dai temi della psicologia della liberazione, individuandone la continuitŕ degli scopi e della metodologia nella psicologia critica di comunitŕ. Tale percorso apre la stra- da a una critica di quei modelli psicologici che centrano l'attenzione unicamente sul singolo, trascurando aspetti sociali, politici, culturali che con quest'ultimo sono interrelati. Da tale critica nasce una nuova declinazione del tema del benessere e della felicitŕ che si apre al confronto con le nuove scienze economiche, e relazionali conducendo alla costruzione di nuovi indicatori sociali di benessere attenti ai temi della partecipazione, e della giustizia sociale. Nello specifico vengono esplorati i temi della equitŕ e della libertŕ in relazione alla felicitŕ evidenziandone i reciproci rapporti.

Authors: Paloma Virginia , Garcěa-Raměrez Manuel , Camacho Carlos
Published: June 2021

La scelta migratoria ha normalmente come obiettivo migliorare le proprie condizioni di vita e, quindi, il proprio benessere. Senza dubbio, queste aspettative non sempre sono soddisfatte, soprattutto in contesti di accoglienza che relegano i gruppi appena arrivati in posizioni di inferioritŕ di potere. Partendo dalla psicologia della liberazione, questo studio ha come finalitŕ quello di indagare a livello empirico la relazione stabilita tra il grado di giustizia nel contesto di accoglienza e il benessere della popolazione immigrata marocchina nel Sud della Spagna. La raccolta dei ricerca ha previsto la partecipazione di 633 immigrati provenienti da 20 unitŕ territoriali dell'Andalusia. I dati mostrano come il livello di benessere del gruppo marocchino sia strettamente connesso con il livello di giustizia del contesto di stabilizzazione. Inoltre, la ricerca pone in luce che l'apertura alla diversitŕ da parte delle comunitŕ di accoglienza, la sensibilitŕ culturale dei servizi comunitari e l'assenza di una segregazione residenziale sono indicatori adeguati della giustizia del contesto. In breve, i dati confermano empiricamente i presupposti teorici difesi dalla psicologia della liberazione.
Principio di realtŕ, nodi tragici e processo analitico
Authors: Schafer Roy
Published: June 2021

Il disagio della civiltŕ occupa un posto speciale nello sviluppo della teoria e della tecnica psicoanalitica freudiana. In particolare alcune sue implicazioni permettono una compren- sione piů ampia del principio di realtŕ. Il concetto dei nodi tragici viene definito ed usato per evidenziare la capacitŕ di Freud di includere gli aspetti tragici della vita in questo principio. Un'ampia sezione č dedicata ad illustrare la diffusione dei nodi tragici in svariati aspetti della vita umana: vittimizzazione, intimitŕ e tutela della privacy. Da ultimo, vengono illustrate le implicazioni per la valutazione clinica dell'elaborazione dei conflitti inconsci.
I temp(l)i del tempo
Authors: Sarsfield Cabral Fatima
Published: June 2021

Il concetto di Augé di "tempo puro" e l'emozione provata nel guardare le rovine dei templi, inducono l'Autrice a fare un'analogia con l'esperienza emozionale all'interno del setting analitico dove i momenti di profonda emozione estetica condivisi da paziente e analista permettono di accedere a un movimento interiore di costruzione o ricostruzione della dimensione spazio-temporale.
Oltre il pluralismo: psicoanalisi e funzionamento della mente
Authors: Pine Fred
Published: June 2021

Soggetti che Freud ha escluso o analizzato in maniera incompleta in oltre un secolo di osservazione sono stati oggetto di indagine teorica: il ruolo dell'altro, il sé, il periodo preedipico, l'azione, il controtransfert, i limiti di neutralitŕ/anonimitŕ/astinenza, i loci del dramma analitico, gli effetti che vanno oltre l'interpretazione e i bisogni di base (vs. i desideri). Questi sviluppi hanno generato teorie contrastanti e gruppi settari. L'autore discute i processi della psicologia di gruppo e propone una visione ampia e inclusiva della psicoanalisi sotto l'intestazione dello studio dei "meccanismi della mente". Offre alcune proposte integrative rispetto ai compiti centrali dello sviluppo individuale, alle teorie della mente, all'approccio relazionale e ad alcuni aspetti tecnici.
Appunti sul processo civile in Germania
Authors: Gattuso Marco
Published: June 2021

- In Germania sebbene ogni giudice incameri ogni anno un numero di cause analogo al nostro, la durata media dei processi civili in primo grado č di pochi mesi. Le ragioni non risiedono soltanto in un processo rigorosamente orale, in motivazioni concise e in una salda direzione del processo da parte del giudice, ma trovano origine anche nelle concrete prassi applicative e nelle soluzioni organizzative adottate in quel sistema.
Flexural (Moment) Capacity of Ultra-high Performance Fiber Reinforced Concrete Beams
Authors: Jamil Madanat
Published: June 2021

Ultra-High Performance Fiber Reinforced Concrete (UHPFRC) is a relatively new generation of cementitious material exhibiting exceptional mechanical characteristics. One of the main applications of this new material is strengthening existing bridges and the construction of new Igirders during the rehabilitation process. Previous research on (UHPFRC) beam girders and prestressed girders found the analytical moment capacity to be 76% of the experimental (test) results. A method based on strain compatibility, equilibrium and the stress-strain relationships is developed to determine the flexural capacity of UHPFRC beams with about 90% accuracy between experimental and numerical capacities. A testing program of five beam specimens is conducted at Ryerson University Structural Laboratory to verify the experimental results. Furthermore, the results of the finite element numerical simulation of ABAQUS software using concrete damage plasticity (CDP) constitutive model predict the flexural capacity of the tested UHPFRC beams reasonably well.
Identifying the variance in the magnitude of landfill impacts on residential property values using multiple regression analysis
Authors: Lim Jong Seok
Published: June 2021

The economic advantage of constructing and operating large-scale landfills over small-scale landfills has been used to justify regional landfills as the solution to the municipal waste management problem. However, the availability of sufficient landfill capacity will have dampening effects on the social efforts to reduce waste and/or divert waste away from landfills, especially when external costs of landfills are not appropriately reflected in the estimation of total costs. In this study, the negative effects of a landfill that are capitalized in property values of houses located in the proximity of two landfill sites ("Britannia" and "Keele" landfill sites representing a small and a large landfill respectively) in the Greater Toronto Area are examined in a single multiple regression equation. The results indicate that the large landfill has greater adverse impacts than the small landfill on property values. This study suggests further analysis in a model to which more independent variables that explain locational characteristics should be added.
Design and Build of an Anthropomorphic Active Vision System
Authors: Shaghaghi Sahand
Published: June 2021

The aim of this thesis project is to design an anthropomorphic active vision system which builds on biomimicry of the human visual system. The proposed system has some of the characteristics associated with such a visual system, such as degrees of freedom associated with movements of the eyes in addition to foveation and vergence capacities associated with human vision.

Through this thesis, novel approaches are proposed in regard to specific elements of system design and system testing. Novel approaches have been proposed regarding foveation and vergence relating to system design and use of Inertial Measurement Unit (IMU) devices incorporating Kalman filters relating to testing of the prototyped device.

For foveation, integration of fast Deep Convolutional Neural Networks (DCNN) has been proposed. For vergence, a variation of Cross-correlation has been used. This method has the benefit of being computationally inexpensive which is beneficial for real-time operations of the proposed system.
Lost in translation : new media, performance, & identity in Quebec
Authors: Goldberg Daniel
Published: June 2021

A descriptive exploration of the impact on contemporary Québécois performing arts by new media and communication technologies, this thesis provides a historical and critical evaluation of "multimedia theatre" in Quebec. Drawing on Turner's theories of performative ritual and Armour & Trott's writing on culture and the Canadian mind, as well as the work of Benjamin, Ellul, Grant, Heidegger, Innis, and McLuhan on technology and cultural production, and the issues of time and space raised by the work of Gilles Maheu, Josette Féral, Patrice Pavis, and Robert Lepage, among others, this thesis argues that while prior research has located Quebec's arts culture in provincial drives for sovereignty and cultural recognition, it might better be understood as a narrative of a people in search of self-identification, offering new perspectives by which to understand an interlinked development of technology and artistic endeavour that has long been in need of critical examination.
Experimental and theoretical studies of composite multiple-box girder bridges
Authors: Androus Anwar
Published: June 2021

Due to their high torsional and wrapping stiffness as well as economic and aesthetic reasons, multi spine composite concrete-deck steel-box girder bridges became a very popular choice in highway bridges. Currently, North American Codes of Practice have recommended some analytical methods for the design of curved multiple-box girder bridges, providing a geometrically defined criterion to establish when horizontally curved may be treated as a straight bridge. To meet the practical requirements arising during the design process, a simple design method is needed for straight and curved composite box girder bridges in the form of load distribution factors. This study consisted of an experimental and a theoretical investigation. The experimental investigation included testing up-to-collapse three bridge models. While the theoretical investigation used a finite element software to examine the behavior of 225 different bridges to extract stress distribution factors for maximum bending stresses that occur at the mid span.
Adaptive signal processing for infrared wireless CDMA systems
Authors: Balendran Balakanthan
Published: June 2021

Infrared system provides a feasible alternative to radio system for indoor wireless communication. Direct spread CDMA format is a promising candidate for infrared transmission system. In indoor systems, transmission is severely impaired by noise and interference produced by artificial light. In this thesis, the performance of the DS CDMA indoor wireless infrared system on diffuse channels is analyzed by taking the effects of inter symbol interference (ISI) and electronic ballast florescent light interference into account. Moreover, to mitigate the effects of ISI and electronic ballast florescent light interference, an adaptive filter technique is proposed for noise cancellation and equalization. This is done by considering a ceiling bounce model for the channel and electronic ballast florescent light for noise. Analytical and simulation results show 7dB improvement in SINR and 10-15 times improvement in BER.
De-noising the CN Tower lightning current signal using short term Fourier transform-based spectral substraction
Authors: Islam Mohammed Jahirul
Published: June 2021

The CN Tower is a transmission tower and it is not unexpected that recorded lightning current signals be corrupted by noise. The existence of noise may affect the calculation of current waveform parameters (current peak, 10-90% risetime to current peak, maximum steepness, and pulse width at half value of current peak). But accurate statistics of current waveform parameters are required to design systems for the protection of structures and devices, especially those with electrical and electronic components, exposed to hazards of lightning. Since more electrical devices are used nowadays, lightning protection becomes more important. So to determine accurate statistics of current waveform parameters, the interfering noise must be removed. In this thesis we describe a technique for de-noising the CN Tower lightning current by modifying its Fourier Transform (FT) where a simulated current waveform (Heidler function) is used to represent the lightning current signal.The limitations of Discrete Fourier Transform (DFT) for removal of non-stationary noise signals, including the noise connected with CN Tower lightning current signals and its properties are discussed. The Short Term Fourier Transform (STFT) is explored to analyze non-stationary signals and to deal with the limitations of DFT. Last of all, an STFT-based Spectral Subtraction method is developed to denoise the CN Tower lightning current signal. In order to evaluate the Spectral Subtraction method, a simulated current derivative waveform ( obtained by differentiating Heidler function) is artificially distorted by a noise signal measured at the CN Tower in the absence of lightning. The Spectral Subtraction method is then used to de-noise the distorted waveform. The de-noised waveform proved to be very close to the original simulated waveform.

A signal-peak to noise-peak ratio (SPNPR) of the CN Tower lightning current signal is defined and calculated before and after the de-noising process. For example, for a typical measured current derivative signal, the SPNPR before de-noising is 7.27, and after de-noising it becomes 151.30. Similarly for its current waveform (obtained by numerical integration) the SPNPR before de-noising is 20,16 and it becomes 361.39 after de-noising. Statistics of current waveform parameters are obtained from the de-noised waveforms. The Spectral Subtraction method is also applied for de-noising the electric and magnetic field waveforms generated by lightning to the CN Tower which enables the calculation of their waveform parameters.
Development of Enhanced Test Methods to Evaluate Alkalisilica Reaction in Concrete
Authors: Sinno Noura
Published: June 2021

Many preventive measures showed improved performance of concrete against alkali-silica reaction (ASR) based on the concrete prism test (CPT) described in the Canadian and American Standards, CSA A23.2-14A and ASTM C1293. However, research has shown that preventive measures that limited the 2-year expansion in the concrete prism test produced late expansion after 7-15 years when tested in the field. The objective of this research is to understand the possible reasons for this late expansion under field conditions and to come up with modified approach to determine the level of supplementary cementing materials (SCM) needed to mitigate the long-term expansion. The research mainly focuses on studying two possible reasons to explain the late expansion. The first reason is the rate and ultimate hydration of SCM, where their capacity to bind alkalis under CPT could be higher than those under field conditions. The other reason for the late expansion could be the geometry and size of the CPT samples which might reduce the expansion due to the excessive alkali leaching. Larger samples showed less leaching compared to standard prisms. 100-mm cylinders showed higher expansion than 75-mm standard prisms; however, both sample shapes showed similar expansions for one tested aggregate when used with SCM. In addition, the capacity of SCM to bind alkalis was shown to be higher at 38ºC compared to the other two tested temperatures investigated in this study: 23ºC and 60ºC. Samples with SCM at high replacement levels expanded more at 60ºC compared to 38ºC. Due to their reduced leaching compared to prisms, testing cylinders at 60ºC showed accelerated results reducing the testing duration to one year compared to the standard test duration of two years. Moreover, a new way to predict the minimum levels of SCM required to mitigate expansion due to alkali-silica reaction is presented showing better correlation with the field. Finally, a fast and reliable test method is suggested to evaluate the reactivity of mineral fillers by adapting and adopting the current test methods available for ASR testing.
The evolving quality and scope of new social movements: Toronto food security organizations mobilizing for change.
Authors: Schieck Elisabeth
Published: June 2021

"This research project investigates some contemporary urban aspects of the politics of food. Taking social movement theory as my theoretical framework, this paper examines the ways in which the practices and services of Toronto organizations such as the Stop Community Food Centre, FoodShare, and Not Far From The Tree promote countercultural food ideologies and thus may be viewed as actors attempting to influence political and social change through food. While individual organizations should not be confused with social movements, it is possible that we may be able look at this ensemble of organizations as an informal network that exemplifies a new contemporary form of social movement."--Pages 3-4.

Development of statistical models to simulate and optimize self-consolidating concrete mixes incorporating high volumes of fly ash
Authors: Patel Rajeshkumar
Published: June 2021

Self-consolidating concrete (SCC), a latest version of high performance concrete, has created tremendous interest today as it can be easily placed in congested reinforced concrete structures with difficult casting conditions. It also reduces the construction time and cost of the labor. Normally SCC is being developed using a superplasticizer to generate desired flow and a viscosity modifying admixture (VMA) to prevent segregation in the concrete. In this research project, instead of VMA, high volumes of fly ash were used along with superplasticizer to develop SCC. The minimum use of superplasticizer and optimum use of fly ash were desired to achieve required properties of SCC. The fly ash is expected to be useful not only in generating the flow but as segregation resistance as well. The aim of the present research project was to develop SCC for sustainable construction by optimizing the use of high volumes of fly ash with some proposed statistical models. The rheological study for paste and mortar was carried out first, and Bingham model parameters such as plastic viscosity and yield stress were correlated with the marsh cone flow of paste and fresh concrete properties such as slump flow and filling capacity. The limits for plastic viscosity, yield stress, and specific marsh cone flow of paste and mortar were identified for concrete mixes to be qualified for SCC. Four independent variables such as total binder content (limit 350 to 450 kg/m3), percentage of fly ash replacing cement (limit 30 to 60 %), % of superplasticizer (limit 0.1 to 0.6 %), and W/B (limit 0.33 to 0.45) were considered for design of experiment and for development of statistical models for SCC. Statistically balanced twenry-one concrete mixes were chosen and fresh concrete tests such as slump and slump flow, V -funnel flow, filling capacity, L-box, bleeding, air content, segregation, and initial and final setting time tests were performed. Seven harden concrete tests (for mechanical characteristics and durability) such as compressive strength (1, 7, 28-day), freezing and thawing cycles resistance, surface scaling resistance, rapid chloride permeability, modulus of elasticity, flexural strength, and drying shrinkage were performed to evaluate the performance of SCC. Five statistical models for important properties of SCC such as slump flow, I-day strength, 28-day strength, rapid chloride permeability, and material cost were developed. The limits of rheological parameters of pastes and mortars can be useful to predict the flow behavior of SCC and the proposed models can be useful to design and optimize SCC mixes incorporating high volumes of fly ash.
Developing New and Optimizing Current Test Methods to Evaluate Sulphide-bearing Aggregate
Authors: El-Mosallamy Mona
Published: June 2021

This research focuses on testing the applicability on aggregates from Ontario of a testing protocol to evaluate the potential oxidation of sulphide-bearing aggregates, optimizing the protocol test methods, and develop new tests based on the obtained results. The protocol comprises of three sequential tests: Total sulphur content, Oxygen Consumption Test and Oxidation Mortar Bar Test. For the oxygen consumption test, using processing equipment with cast iron media, was found to contaminate the samples and produce high consumption. Moreover, controlling the tested aggregate gradation produces higher consumption and more consistent results than using a fine aggregate sample (<150µm) without controlling the minimum size. The oxidation consumption test showed lower expansion values for carbonate aggregates compared to aggregates with high silicate content. Exposing siliceous aggregate, whether alkali-silica reactive or not, to the high pH from the oxidizing solution and the high temperature produces high expansion regardless of the oxidizable sulphide content. As such, new expansion criteria are suggested which takes into consideration the silicate content of the aggregates. The dissertation proposes, based on testing twenty-six aggregates, modifications to: the oxygen consumption test; the expansion criteria of the mortar bar test; and proposes a new oxidation mortar bar test to avoid the limitation of the applicability of the original mortar bar test on siliceous aggregates. In the new testing program, different testing regimes were investigated using different oxidizing agents and environmental conditions that can promote oxidation of sulphide-bearing aggregates, without the promotion of other chemical reactions (Alkali silica reaction products or Friedel’s’ salt). Out of the various investigated tested regimes, two testing procedures showed promising results and recommended for further development and use. Bleach and lime water are used in these tests as the oxidizing agents; however, mortar bars in both regimes are stored at lower temperature compared to that of the original test in the protocol. Based on the expansion results, new expansion criteria are suggested that can detect if the aggregate contains oxidizable sulphides.
Too hot for the library: access to films with sensitive content
Authors: Wong Olivia Fay
Published: June 2021

This thesis explores decisions on access to collections with sensitive content through a case study analysis of the library principles and archival practices applied to the films from the Youth Film Distribution Center (YFDC). These films are overseen by the Reserve Film and Video Collection at The New York Public Library for the Performing Arts, Dorothy and Lewis B. Cullman Center. The Reserve Film and Video Collection has been the principal circulating audiovisual department for The New York Public Library since the 1950s. The objective of this thesis is to explore processing decisions for films with sensitive content (e.g. films promoting negative stereotypes of their subjects or featuring violent or sexually explicit content). The thesis offers an historical overview of the Youth Film Distribution Center and outlines the processing decisions surrounding levels of access for the YFDC title Seeing (1972).
Effect of Different Design Parameters on the Cyclic Response of Reduced Beam Sections (RBS) Moment Connections
Authors: Naqvi Syed Asad Abbus
Published: June 2021

After the 1994 Northridge earthquake, research has been conducted to develop new types of beamcolumn moment connections, such as Reduced Beam Section (RBS) connections. This study performs a sensitivity analysis of the cyclic response of RBS connections using detailed finite element simulation. The significance of the effect of twenty-one factors is assessed using a statistical design of experiment method. The input factors are related to the material properties or the geometry of the beam-column connection. A two-level fractional factorial design is used to create factor combinations for the sensitivity analysis. The cyclic response of RBS connections is assessed in terms of five response variables, including: the total dissipated energy, initial stiffness, strength degradation rate, maximum moment capacity and rupture index at 7.5% storey drift. The sensitivity analysis results show that the beam depth has the greatest influence on the cyclic response of RBS connections.
Prototyping a GIS-Based Spatial Decision Support System in a Manufacturing Environment
Authors: Gao Xiang Qian
Published: June 2021

Current spatial decision support systems (SDSS) in manufacturing environments, which are mostly CAD-based, have many drawbacks and thus may make less effective and efficient spatial decisions. GIS-based SDSS can overcome those drawbacks and support decision-making in a much effective manner. Unfortunately, there is little research on GIS-based SDSS in a manufacturing environment. This thesis study focuses on a systematic approach to the development of GIS-based SDSS in a manufacturing environment. By using Trane China as an example, the prototype of Trane China SDSS (TCSDSS) is developed by adopting the unified software development process. The TCSDSS prototype contains eight object modules, which incorporate ArcGIS embedded models, ArcGIS feature data, and MS Access attribute data, to support decision-making in Trane China. The benefits from the use of the TCSDSS prototype that have been found include its spatial analysis, network analysis, and 3D analysis functions besides the improvement on communication and efficiency. It is also found that the newly developed GIS software packages such as ArcGIS 8.3, with the enhanced drawing functions, can provide enough adequate precision level required by facility layout.
The gift and the threat: an artistic exploration into the machine's threat against the flesh body
Authors: Petrou Laurie
Published: June 2021

This paper acts as a support for the two projects I have submitted: Industrial Strength and The Gift The Threat. The projects and the paper examine ideas of the threat of the metallized body on the flesh body. Aesthetics and texts vitalized ideas that were explored through the videos, and the videos themselves represent an artistic discovery and a contribution to aesthetics, history and philosophy - as well as a springboard for a larger body of work. My research involved analysis of the fascists and the Futurists and their use of the machine and machine-body ideals, the cult of the engineer, rhetorical applications of the Mechtech machine as determined by Barry Brummett as well as examination into texts and imagery involving the body, dance, military aesthetics and finally, much personal discovery.

The process of making the two videos revealed my own position on the topic of the body - filming my own body in relation to texts and imagery analyzed, I was forced to answer questions of how I felt about the body, technology, spirituality and art making, all within an academic and artistic context.

The footage and soundtrack in both videos are original (save for one still image) and were composed using a process that I explore at length in the paper: spiritual and highly personal, the process divulges much about the artist, and likewise, I hope that the reading of the projects offers discovery for the viewer in the form of personal questions of the body and the machine.

The possibility for further artistic and academic work on the ideas examined in these projects is exciting: my focus was solely on the Mechtech machine (gears and pistons, and what we would know as factory machinery), fascism and the body, but there are many ideas one could expand upon, including a study in gender and machine aesthetics; contemporary machines and the body; and the body and mechanical/flesh motion. My hope is that these projects inspire questions, ideas and further pursuits based on the topics explored within the works and paper.
Hazardous Waste Transportation: an Overview
Authors: Ashiq Muhammad
Published: June 2021

Increasing industrialization and globalization has spawned the unprecedented generation of environmental toxic and hazardous wastes. The existence of publicly known hazardous waste problems such as toxic spills, and river pollution that pose serious and very real threats to human health puts extensive pressure on the government to take an aggressive role in hazardous waste control and transportation. The main objective of hazardous waste transportation is public safety. Each government has the responsibility to ensure that hazardous materials should be transported safely for the social and economic good of the country. Hazardous waste management is now a major and urgent global concern. Various techniques, models, and guidelines for the perception of risks associated with the transport of the hazardous materials are developed. Database of the accident data are developed by transportation agencies to be used for the development of models to improve safety of hazardous waste transportation. Based on the available risk perception models, accident models, the type of hazardous material, origin/destination, and the availability of emergency response routes for their transport are properly designed. Advanced technologies, automated vehicle location system (AVL) and geographical information system (GIS) are also used for the analysis and modeling for the safe transport of hazardous materials. The purpose of this project is to present a literature review of hazardous waste materials and their impact on human health, regulations to control the movement of hazardous materials, Basel Convention and its effectiveness, treatment and disposal of hazardous materials, model developments for risk perception and management and the use of advanced technologies for safe transportation of hazardous wastes. Based on the literature review, the conclusions and future recommendations for possible improvement of the models and techniques used for safe transportation of hazardous wastes are presented.
Colonial costuming: representations of playing Indian in photographs, settler Colonialism and the appropriation of native North American culture
Authors: Forster Hikka Ingrid
Published: June 2021

This thesis examines the cultural significance of “playing Indian” in photographs: the practice of non-Native peoples dressing up in Native North American costumes and posing for photographs. It addresses photographs made both inside and outside the studio of people playing Indian, during both the later part of the nineteenth and early twentieth centuries and looks at the extent to which these photographs reinforce settler colonial ideology prevalent within white society during this time period. Examples from two collections will be explored, portraits from the Notman photography collection at the McCord museum, which includes examples of white Europeans and North Americans dressing up in Native “costumes” and photographs of children playing Indian in the First Nations collection at the Archive of Modern Conflict Toronto. Themes of masculinity, nation-building, “Canadianness,” and childhood in relation to indigeneity are explored by situating the photographs within their historical and cultural context and subsequently relating them to the already existing theories on playing Indian.
Investigating Approaches to Advancing Knowledge on the Effects of Road Safety Treatments: An Application to Ontario Rural Two-Lane Highways
Authors: Lindley Ian
Published: June 2021

Crash modification factors (CMFs) are important tools for understanding the safety benefits of treatment options. However, CMFs typically lack variability as they apply a single factor to all the sites that are treated by these road safety measures. Crash modification functions (CMFunctions) are one way to capture the variability of CMFs as a function of independent variables. This research conducted a case study on the application of edgeline, centreline and dual rumble strip treatments on Ontario provincial highways and investigated CMF variability by developing CMFunctions as well as separate CMFs for tangent and curved sections. Curved sections experienced greater benefits from the application of the rumble strips. In conducting the study, the Highway Safety Manual’s application of rumble strip CMFs to Ontario roadways was also explored.
Control of oil spills in urban areas
Authors: Chui Jenny King-Lai
Published: June 2021

The City of Toronto has experienced about 300 oil spills per year (Li 1997). Traditionally, the city recommends that businesses and industries practise pollution prevention and install on-site oil separators. Currently, the sizing criteria for these devices are not well defined and the draft code of practices for oil separators by the Canadian Petroleum Product Institute (1994) has not yet been approved by the Ministry of the Environment (Li 2000). Thus, the city is currently investigating the possibility of installing oil separators at spill prone sewer outfalls. The new application of oil separators at sewer outfalls requires that the devices be operable under high flow conditions and that their capacity should reflect the land use characteristics in the associated sewershed.

This study has developed an innovative spill control device for the Humber Creek outfall and a Geographic Information System (GIS)-based analysis technique for urban oil spill management. First, a flow diversion structure was designed to

capture the dry weather flow at the outfan and to transport the captured flow into an

oil/water separator designed in accordance to the American Petroleum Institute's

manual (1990). The designs of the flow diversion structure and the oil/water

separator were evaluated by a physical model study using the National Water

Research Institute's Hydraulics Laboratory at the Canada Centre for Inland Waters in Burlington, Ontario. Then, the GIS-based analysis technique was used to identify

potential treatment options for spill-prone sewer outfall in the Town of Richmond

Hill.

It was found that (I) the spill event characteristics should be analyzed in order

to develop design criteria for oil spill control systems; (2) the preliminary design of

the oil spill control system at Humber Creek was different from the API's

methodology; and (3) the physical model investigation confirmed the conveyance

capacity of the diversion channel and the general behaviour of the tilted-plate

separator.

A database of oil spill records in the Greater Toronto Area from 1988 to 2000

were compiled and geo-referenced. By overlaying the spill characteristics and other

GIS data layers, such as woodlots, wetlands and watercourses, spill prone areas were

identified. In order to increase the accuracy of the analysis, the percentage of georeference

oil spill locations should be increased.

Optimally weighted local discriminant bases : theory and applications in statistical signal and image processing
Authors: Hazaveh Hesarmaskan Kamyar
Published: June 2021

This thesis is concerned with Local Discriminant Basis (LDB) algorithm, its properties, optimization and applications in feature extraction and classification. LDB algorithm targets features extraction from redundant dictionaries such as wavelet packets or local trigonometric bases at low computational complexity.

As the main contribution of this thesis, an optimization process is introduced to further improve the accuracy of the overall scheme in applications when a region of interest can be specified by the experts in the field of application (based on LDB selected features) to further characterize signal classes in smaller regions. Audio signal and textured image classifications are practical applications that are studied in this thesis to test the efficiency of optimally weighted local discriminant basis algorithm (OLDB) as a feature extraction scheme. Various properties of the algorithm such as noise behavior and stability analysis are studied from an engineering perspective. The implementation aspects of the algorithm in one dimension are reviewed as well as in two dimensions that serve as implementation guidelines.
Truck stability on different types of horizontal curves combined with vertical alignments
Authors: Dabbour Essam Mohamed S. A. E. A.
Published: June 2021

The combination of horizontal curves with vertical alignments is commonly used in different classifications of highways; either on highway mainstream or on highway interchange ramps. The horizontal curves, combined with vertical alignments, may be single, compound or reverse horizontal curves. The current design guidelines do not adequately investigate vehicle stability on such three-dimensional (3D) alignments. Computer software that simulates vehicle behaviour on different geometrical alignments was employed to investigate vehicle stability on such 3D alignments. It was found that vehicle safety is questionable, especially for larger vehicles on reverse curves associated with vertical alignments. The critical speed, where the vehicle starts to rollover or skid, was found to be close to design speed for those 3D alignments. Design aids were then developed to address the recommended solutions to maintain the margin of safety required.
Effect of Axial Deformation Caused by Torsion on a Solid Steel Cylinder
Authors: Forsey Dawson
Published: June 2021

Equations describing the classical theory of applied torsion and axial rotation on a solid cylindrical shaft have been modified by Shirali and Hossain (2019) to derive new theorems, which can take into consideration axial deformation of members. The modified theorems use various empirical parameters to introduce the combined effect of axial force, axial displacement and axial rotation, which is neglected in classical theorems of torsion. Multiple finite element analysis models for solid steel cylindrical members, fixed at one end and subjected to torsion at its free end, were developed to study the effects of torsional loading. The effect of axial deformation/stress developed in the cylinder is analyzed and compared with values predicted by classical and proposed modified theorems (equations). It is shown that the cylinder can shorten or elongate when subjected to torsion. The proposed theorems/equations, based on axial deformation subjected to torsion, provide more accurate predictions of shear stress and axial rotation (angle of twist).
Safety evaluation of left-turn priority phasing at Toronto intersections

Published: June 2021

Traffic accidents cause a huge loss to the society. According to statistics, 50% of all accidents occur at urban intersections and 47% of these are due to left-turn collisions. Countermeasure Implementation at these locations therefore can play a vital role in the improvement of traffic safety.

This study illustrates a methodology for evaluation of urban 4-legged signalized intersections treated with left-turn priority phasing. The methodology is applied to three important collisions types: those due to left-turn collisions; those due to left-turn side impact collisions; and all impact types combined collisions. Data used in this analysis were obtained from the City of Toronto. Safety Performance Functions for left-turn and all impact types combined collisions which were developed by the City of Toronto, were calibrated and used in an empirical Bayesian methodology that was employed to estimate the expected frequency of accidents occurring at each intersection in order to evaluate the effectiveness of left-turn priority phasing in reducing this frequency.

The results revealed that left-turn priority phasing can be an effective treatment for addressing and reducing the number of collision at signalized intersections. Flashing advance green phasing is more effective in improving safety for two of three types; all left-turn and all impact types combined collisions. Left-turn green arrow (protected/permissive) phasing is more effective for left-turn side impact collisions. By implementing this type of treatment, the number of crashes and the associated monetary loss to society could be significantly reduced.
Performance Evaluation of Soil Cell
Authors: Chen Lianghao
Published: June 2021

Soil Cell is a novel Low-Impact Development practice that is suitable for densely developed urban environment.

This thesis seeks to gain further understanding of soil cell’s performance in terms of water quality and quality control; and to assess the exfiltration performance of perforated pipe in soil cells by monitoring an active cell.

The monitoring result showed that the cell was very effective in treating particulate (90% concentration reduction), metal (91% lead concentration reduction to 53% copper concentration reduction) and phosphorus (74% concentration reduction). The cell was ineffective in treating chloride (1% concentration increase, no statistical significance) and even caused nitrate leaching (65% concentration increase).

Field performance of the soil cell indicated that the inflow perforated backed up frequently, restricting the flow into the cell but laboratory testing of the perforated pipes’ hydraulic performance confirms that the pipe has a sufficient capacity to convey the flows of up to 10 L/s.
Climate Change Impact on Design and Building Criteria of Infrastructure Assets - Simulation Model
Authors: Brahimi Youcef
Published: June 2021

Current design codes and criteria for the construction of infrastructure assets is unable to account for anticipated environmental changes due to climate change. This study developed a simple simulation model based on MS Excel Precision Tree to consider the effects of adding a correction factor for climate change to justify then intent to proceed or not with a construction project. After many iterations, it appears that climate change can result abandoning certain projects as any investment in them would to be beneficial.

A simulation model was also developed to determine the allocation of funds for an initial construction project using climate change control parameters. This model showed that for a 100-year span, on average, there would be a deficit caused by costs involved with repairing the asset due to climate change deterioration. This can be counteracted by attributing 95% contingency to reduce the risk of climate change damage to 5%.
Development of an urban travel demand model of the Town of Oakville
Authors: Pawlowski Lukasz
Published: June 2021

This dissertation documents the development of a travel demand model of the Town of Oakville. The purpose of the model was to predict traffic demand on study area roadways during the morning peak hour. The model focused on the prediction of auto driver trips. The model was developed based on the 1996 Transportation Tomorrow Survey data, available from the Data Management Group at the University of Toronto.

The model was developed in accordance with the Urban Transportation Modelling System (UTMS) of models. Activities included: Trip Generation, Trip Distribution, and Trip Assignment. Accounting for Mode Split was unnecessary as the model focused only on auto driver trips. The final product of the model is a set of traffic flows over links in the transportation network.

The model was developed using TransCAD transportation GIS (Geographic Information System) software. TransCAD is a microcomputer software specifically designed for transportation planning and data management.
