Estimating Vehicle Infrastructure: Downtown Albuquerque, New Mexico, Zachery Phillip Baiamonte

Architecture and Planning ETDs

Cities have little knowledge about their parking infrastructure despite clear evidence that abundant parking has environmental, economic, and transportation consequences. The objective of this thesis is to illustrate the need to accurately estimate the area dedicated to vehicle infrastructure (parking lots and streets) within urban areas. I focused on a method that estimated the vehicle infrastructure area within the Downtown Core of Albuquerque, New Mexico, by cross-referencing geospatial cadastral data with minimum parking requirements. Three parking space types were identified: 1) parking in structures; 2) surface parking (parking lots and residential driveways); and 3) on-street parking. To illustrate the need …

Energy Efficiency Retrofit And Decarbonization Of Old And Historic Buildings In California, Daria Nikolaeva

Master's Projects and Capstones

Buildings are responsible for almost 40% of total global greenhouse gas emissions and the retrofitting of existing buildings is an essential part of solving the problem. About 75% of buildings in Californian were constructed before the first energy-efficiency building code was adopted in 1978. Old buildings are inefficient, responsible for large carbon footprints and must be retrofitted to stay on track with the state's climate targets. However, current policies do not require substantial changes and tend to favor historic preservation over energy efficiency, missing improvement opportunities. Recognizing the significance of carbon intensity, the 2019 California Energy Efficiency Action Plan shifted …

Architectural Representations Of Human Rights, El-Bastawissi Y. Ibtihal, Youssef Maged

BAU Journal - Creative Sustainable Development

The United Nations defines the Human Rights as the rights of all human beings, regardless of race, gender, language, religion, nationality, or any other status. These rights include all claims to live freely, to educate and work in equality, and to inhabit humanistic urban and architectural spaces. Throughout the history of architecture, civilisations have generated different perspectives towards respecting the human rights. Temples of Ancient Egyptian Architecture crushed the human scale to introduce religious experiences to their visitors. Tibetan temples over mountains enforced people to make anti-humanistic journeys to reach them. After thousands of years, the mega-scale palaces and cathedrals …

Travel Behavior Change And Economic Transition In Gentrified Neighborhoods, Maryam Izadi

University of New Orleans Theses and Dissertations

Post-industrial cities in the US have experienced social and economic transitions, mostly in declining downtown neighborhoods. This process, known as gentrification, typically involves revitalization that reverses the decline and disinvestment in inner-city neighborhoods. The industrial shift increased the demand for housing near downtown. The employment of college-educated and high-skill workers has been centralized, while low-skilled jobs continue to decline downtown. While the impacts of gentrification on housing and residential displacement is frequently investigated, little attention has been given to its impact on travel behavior change and economic transition, which is the focus of this research. Change in travel behavior is …

Foreign Object Debris Detection For Airport Pavement Images Based On Self-Supervised Localization And Vision Transformer, Travis Munyer, Daniel Brinkman, Xin Zhong, Chenyu Huang, Iason Konstantzos

Durham School of Architectural Engineering and Construction: Faculty Publications

Supervised object detection methods provide subpar performance when applied to Foreign Object Debris (FOD) detection because FOD could be arbitrary objects according to the Federal Aviation Administration (FAA) specification. Current supervised object detection algorithms require datasets that contain annotated examples of every to-be-detected object. While a large and expensive dataset could be developed to include common FOD examples, it is infeasible to collect all possible FOD examples in the dataset representation because of the openended nature of FOD. Limitations of the dataset could cause FOD detection systems driven by those supervised algorithms to miss certain FOD, which can become dangerous …

Characterizing And Modeling The Coupled Hydro-Mechanical Cyclic Behavior Of Unsaturated Soils Using Constant Water Content Oedometer And Direct Shear Tests, Beshoy Riad, Xiong Zhang

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Most transportation infrastructures are constructed on compacted soils that are typically unsaturated above the groundwater table. The soils are subjected to cyclic traffic loadings and seasonal wetting–drying cycles. Although problems associated with unsaturated soils are ubiquitous in the US, coupled hydro-mechanical analysis is rarely included in the design/analysis of transportation geosystems. This can be attributed to two main reasons: (a) there are no simple devices/methods which can be used to rapidly characterize stress–strain behavior for unsaturated soils, and (b) there is a lack of a constitutive model to study coupled hydro-mechanical cyclic behavior for unsaturated soils in a consistent way. …
