Investigating The Presence Of Culture In Engineering Design: A Case Study On Culture In Design Methods, Perception, And Outcomes, Malena Ataa Durowaah Agyemang

All Dissertations

Overwhelming global statistics on economic, social, and health disparities has driven engineers and designers to develop solutions to minimize these disparities [1,2,11,12,3–10]. For the scope of this study, these efforts are referred to as design for humanitarian engineering and global development (HEGD). HEGD solutions are designed to improve access to medical technologies, energy, clean water, and even spark economic development [1–10]. However, many HEGD solutions go unadopted, halting their intended benefits [9,13,22,23,14–21]. Efforts to improve HEGD adoption have focused on ways to incorporate culture in the design solution’s aesthetics or in approaches post-deployment [24,25,34,35,26–33]. However, a review of failed HEGD …

Development And Application Of Sustainable Binders Comprising Of Fly Ash And Ground Glass Fibers In Portland Cement And Geopolymer Concrete, Omar Alsanusi Amer

All Dissertations

Since cement production is responsible for a significant share of anthropogenic CO2 emissions, the sustainability of concrete construction has become one of the most targeted research and construction industry goals. Many suggestions have been in use to encourage sustainability of concrete construction; one such approach is to partially replace cement by industrial byproducts. The most known industrial byproduct used in concrete construction worldwide has been fly ash, which is a byproduct of burning coal for power generation.

Fly ash use in concrete has various benefits. It reduces the water demand, reduces plastic shrinkage, reduces permeability, and thus improving the durability …

Production And Characterization Of Uranium Sol Gel Surrogates Produced With Cerium Acetate And Cerium Nitrate, Matthew Brett Alford

All Dissertations

For the production of ceramic microspheres for future space travel, new methods of processing must be explored. The sol gel method proves promising for the production of uranium-based ceramic microspheres that are consistent enough in size and shape for such an application. A process for producing these microspheres has already been established, but there are avenues for improvement.

Handling of radioactive material like uranium is not always possible or warranted. As such, a non-radioactive surrogate that greatly resembles the processing of its actual radioactive counterpart. Herein this work a cerium-based surrogate is developed to closely resemble an already established process …
