Transportation And Land Use Planning For Healthy Cities, Naser Ahmed

Electronic Thesis and Dissertation Repository

Healthy cities provide physical and mental health benefits to citizens. To promote scientific transportation and land use planning for healthy cities, robust geospatial methods are required. This thesis introduces two new geospatial methods to facilitate healthy transportation and land use planning. First, to help healthy land use planning, a new analytical framework for identifying green space deserts based on various walking distance thresholds is introduced. This method is particularly useful in low-middle-income countries in the Global South where guidelines for proper walking distance thresholds to green spaces are missing. Second, to aid healthy transportation planning, a new measure of transit-based …

Optimization Of Advanced Building Integrated Photovoltaic And Thermal System With Dual Working Fluid, Barilelo E. Nghana

Electronic Thesis and Dissertation Repository

A direct exchange building integrated photovoltaic and thermal (BIPV/T) heat pump system is proposed where the heat extracted from the BIPV is used to drive the heat pump. To ensure a more stable diurnal system performance, especially at low solar conditions, air flow is instituted in the cavity between BIPV façade and the insulated inner wall. The airflow is directed from the heated or cooled space into the air channel and can be exhausted or returned to the space depending on the building operating conditions. The flow and geometrical parameters of the BIPV/T façade are optimized such that more than …

An Investigation Into The Curation Of Archaeological Collections In Cultural Resource Management In Ontario, Canada, Vienna Raven Mann

Electronic Thesis and Dissertation Repository

This study aims to investigate why and how there is a “curation crisis” in Ontario archaeology by examining the delegation of responsibility for archaeological collections. This research was conducted by reviewing related scholarly literature, investigating the current legislation governing Ontario archaeology, and interviewing 20 stakeholders involved in archaeological collections management, including Cultural Resource Management (CRM) archaeologists, descendant community representatives, past Ministry of Heritage, Sport, Tourism, and Culture Industries employees, academic and avocational archaeologists, and museum or repository curators. Nearly all participants think CRM archaeologists should not be responsible for the long-term curation of archaeological collections, yet many of Ontario’s archaeological …

Numerical And Semi-Analytical Estimation Of Convective Heat Transfer Coefficient For Buildings In An Urban-Like Setting, Anwar Demsis Awol

Electronic Thesis and Dissertation Repository

Urban building arrangements such as packing density, orientation and size are known to influence the microclimate surrounding each building. Studies on the impact of urban microclimatic changes on convective heat transfer coefficient (CHTC) from a stock of buildings, however, have been rare in surveyed literature. The present study focuses on numerical and analytical investigation of CHTC from building-like models with homogeneous set of equal and unequal planar and frontal densities. Consequently, the study discusses the CHTC response in relation to broader changes in the urban surface form. Part of the process involves the development of a simplified one-dimensional semi-analytical CHTC …

Transient Analysis Of Full Scale And Experimental Downburst Flows, Junayed Chowdhury

Electronic Thesis and Dissertation Repository

Downbursts are highly transient natural phenomena which produce strong downdrafts evolving from a cumulonimbus cloud They induce an outburst of damaging winds on or near to the ground causing an immense damage to the ground mounted structures and aircrafts. This study investigates the transient nature of downbursts using wind speed records from full scale downburst events employing an objective methodology. This method can detect the abrupt change points in a downburst time series based on statistical parameters such as mean, standard deviation and linear trend. In addition to the analysis of the full scale downburst events, several large scale experimental …

A Simulated Walk In Nature: Testing Predictions From The Attention Restoration Theory, Corey Crossan

Electronic Thesis and Dissertation Repository

Attention Restoration Theory (ART) predicts that top-down processing during everyday activities can cause attentional fatigue and that bottom-up processing that occurs when people experience nature will be restorative (Kaplan, 1995). The present study examined this prediction by exposing participants to three different conditions using a repeated measures design: a control condition during which participants walked on a typical treadmill, a nature/restorative condition during which participants walked on the same treadmill, experiencing a simulated nature walk, and a perturbation condition that included the same simulated nature scene but also required top-down processing during the walk. The findings supported ART predictions. As …

Imagining The Unimagined Metropolis: Privilege, Liminality, And Peripheral Communities In The Contemporary Urban Situation, Colton R. Sherman

Electronic Thesis and Dissertation Repository

Various works of psychogeographic literature explore privileged and non-privileged communities and spaces through narrative and character development. Novels of this sort—specifically those by China Miéville, Neil Gaiman, and J.G. Ballard—feature narratives where their respective protagonists undergo a liminal metamorphosis and transform from a monotonous, albeit privileged urbanite into a free-associating inhabitant of the urban periphery: the unimagined, non-privileged space of urban detritus. By engaging with these authors’ novels alongside the works of the Situationists, Walter Benjamin, Rob Nixon and others, the goal of this thesis is to explore how the dominant urban epistemologies are subverted—whether or not they should be …

La Identidad Cultural A Través Del Espacio Urbano Y Arquitectónico En La Ciudad De México: El Caso De La Villa De Guadalupe, Jamil Afana

Electronic Thesis and Dissertation Repository

Today, the revered sanctuary of Tepeyac where the Virgin Mary of Guadalupe appeared in 1531, is one of the most visited sites in Mexico and one of the most culturally characteristics spaces of Mexico City. The urban and architectural space of guadalupanista sacred enclosure has continuously transformed since the sixteenth century. This focuses primarily on the years 1976 to 2011 to analyze the Mexican cultural identity that has developed during that time. Both dates are important because they represent the last two built interventions within the sanctuary and they mark the urban image of the sacred space and surroundings. In …

Coordinated Autonomic Managers For Energy Efficient Date Centers, Forough Norouzi

Electronic Thesis and Dissertation Repository

The complexity of today’s data centers has led researchers to investigate ways in which autonomic methods can be used for data center management. Autonomic managers try to monitor and manage resources to ensure that the components they manage are self-configuring, self-optimizing, self-healing and self-protecting (so called “self-*” properties). In this research, we consider autonomic management systems for data centers with a particular focus on making data centers more energy-aware. In particular, we consider a policy based, multi-manager autonomic management systems for energy aware data centers. Our focus is on defining the foundations – the core concepts, entities, relationships and algorithms …

Adapting To Climate Change: The Case Of Multi-Level Governance And Municipal Adaptation Planning In Nova Scotia, Canada, Brennan A. Vogel

Electronic Thesis and Dissertation Repository

Nova Scotia is the only province in Canada to use the gas tax as a financial incentive to create a regulatory mandate for ‘Municipal Climate Change Action Plans’ (MCCAPs). The MCCAP adaptation policy mandate initiated and enabled climate change vulnerability assessment and the development of climate risk priorities and adaptation plans to uniformly occur at the local scale in 53 Nova Scotian municipalities. This dissertation seeks to answer the question: What are the social factors that impacted municipal climate change adaptation policy and planning processes in the multi-level governance context of Nova Scotia’s MCCAP?

The study develops and operationalizes a …

Estetica Urbana De Una Polarizacion, Edgar E. Yanez

Electronic Thesis and Dissertation Repository

This work examines the changes in the Venezuelan city of Caracas during the Bolivarian Revolution during the years 1999 through 2013, under the rule of Hugo Chavez Frias (1954-2013). Stressed by a profound polarization (commonly interpreted as political), this period brought aesthetic and spatial changes, which have affected the life and perception of the city. From a neo-populist discourse inspired by the idea of the establishment of the republic under a socialist model, the Bolivarian Revolution has stripped issues that affect the sense and urban rooting such as identity, racial segregation or class struggle in addition to political differences. Reflecting …

Wind-Induced Pressures In Air Permeable, Double-Layer Roof Systems In Regions Of Separated Flow, Jeong Hee Oh

Electronic Thesis and Dissertation Repository

This thesis is concerned with the wind-induced pressure distribution acting on air permeable, double-layer roof systems placed on low-rise buildings. Because of the pressure transmission into the cavity between layers, the pressure difference in the double-layer systems differs significantly from that in a single layer. The interior pressures (in the cavity between layers) are highly correlated with external pressures at the openings on the external surface of the outer layer and thereby, the net wind load for the design of the outer layer is considerably reduced by the pressure equalization between the external and internal surfaces of the outer layer. …

Composing The Cities Of Flow: Unitary Urbanism And The Ontology Of Water Infrastructure, Angus R. Currie

Electronic Thesis and Dissertation Repository

A renewed interest in ontology and the ontological station of erstwhile considered humans and nonhumans has provoked interest in the implications that such station might hold for the built, metabolized, and governed environment. It is the contention of this work that the contemporary manifestation of hydro-social assemblages, water distribution networks, reflects and is produced by a totalizing spectacular ideology that relies on such networks being imbricated in such a manner as to de-emphasize or deny their ontological standing. Perceiving in the Unitary Urbanism articulated by the situationists of the 1960s an anticipation and critique of such spectacular ideology, and its …
