ASU Electronic Theses and Dissertations
This collection includes most of the ASU Theses and Dissertations from 2011 to present. ASU Theses and Dissertations are available in downloadable PDF format; however, a small percentage of items are under embargo. Information about the dissertations/theses includes degree information, committee members, an abstract, supporting data or media.
In addition to the electronic theses found in the ASU Digital Repository, ASU Theses and Dissertations can be found in the ASU Library Catalog.
Dissertations and Theses granted by Arizona State University are archived and made available through a joint effort of the ASU Graduate College and the ASU Libraries.

Results revealed that lighting can affect four aspects of the overall dining experience; atmosphere, service, sociality, and food. This research revealed a new perspective when looking at the impact of lighting in a certain context, beyond the atmosphere perception. The results of qualitative data and quantitative data were combined and produced two main reference tables for lighting at upscale restaurant setting; lighting characteristics and approaches, and lighting fixtures. These two tables operate as guidelines for successful lighting practices in upscale restaurants. This research demonstrates the applicability of the ‘DineLight’ instrument to reveal new insights regarding the upscale dining experience, contributing not just to research in the area of lighting design, but also providing practical applications for restaurateurs and others in this industry.
Food is an important cultural artifact in the world. However, past research in design suggests that the discipline has mainly focused on food as a catalyst for creativity and imagination or as a tool to examine materialistic, economical, sensorial, and emotional connections. Studying the user-focused involvement in the creation of food artifacts and focusing on cultural, global, and historical aspects of that participation are important to address the gaps in the knowledge required to solve increasingly “wicked problems” (Buchanan, 1992; Rittel, 1971). To achieve this goal, Eat Your Heart Out implemented a comparative practice-based study of the Indian street foods in Mumbai and Phoenix to examine consumption, production, and distribution practices at both places. The methodological design was highly multi-disciplinary in nature and included rapid ethnographic assessment, interviews, visual research, and a generative method of co-creation.
The study revealed that street foods as cultural artifacts were deeply rooted in specific traditional values specific to the context, which significantly influenced personal and communal consumption, production, and distribution practices of Indian street foods in Mumbai and Phoenix. The values of standardization, formality, and higher food regulation practices limited the diversity and radically transformed the central values of Mumbai’s street foods when the foods re-territorialized in Phoenix. This resulted in lowering the consumption.
Eat Your Heart Out presents cultural and practical insights into the interactions between contexts, artifacts, practices, and participants. Eat Your Heart Out recommends new frameworks of correlation for various consumption and production practices and suggests how street food artifacts alter when they move across cultures. Such knowledge can be valuable for similar ethnic food culture studies and the development of innovative research tools incorporating transnational and multidisciplinary methods in the future.
On a broader scope, Eat Your Heart Out provides a unique opportunity to study a culture that has not been examined by scholars much in the past. It also focuses on gaining knowledge about ethnic culinary practices of Indian immigrants in the United States and encouraging enhanced cross-cultural acceptance.
Significant hardening and degradation parameters such as stiffness, crack spacing, crack width, localized zone size are obtained from tensile tests using digital image correlation (DIC) technique. A tension stiffening model is used to simulate the tensile response that addresses the cracking and localization mechanisms. The model is also modified to simulate the sequential cracking in joint-free slabs on grade reinforced by steel fibers, where the lateral stiffness of slab and grade interface and stress-crack width response are the most important model parameters.
Parametric tensile and compressive material models are used to formulate generalized analytical solutions for flexural behaviors of hybrid reinforced concrete (HRC) that contains both rebars and fibers. Design recommendations on moment capacity, minimum reinforcement ratio etc. are obtained using analytical equations. The role of fiber in reducing the amount of conventional reinforcement is revealed. The approach is extended to T-sections and used to model Ultra High Performance Concrete (UHPC) beams and girders.
The analytical models are extended to structural members subjected to combined axial and bending actions. Analytical equations to address the P-M diagrams are derived. Closed-form equations that generate the interaction diagram of HRC section are presented which may be used in the design of multiple types of applications.
The theoretical models are verified by independent experimental results from literature. Reliability analysis using Monte Carlo simulation (MCS) is conducted for few design problems on ultimate state design. The proposed methodologies enable one to simulate the experiments to obtain material parameters and design structural members using generalized formulations.
