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. …

However, the increasing adoption of DG is creating new obstacles for system operators due to the uncertainty in forecasting future demand. One concern is the possibility of facing a utility death spiral as a feedback loop between, on the one hand, the increasing adoption of DG and increasing electricity rates to cover generation and transmission overheads with, on the other hand, reduced …

The Museum As Object Of Display: Experiencing The Ashmolean, Jack Z. Chen

Armstrong Undergraduate Journal of History

Conventionally, museums are most often considered as a series of objects displayed, but I argue that the museum itself should be seen, first and foremost, as the object on display. The Ashmolean Museum in Oxford, built at the high tide of British Imperialism, is a very interesting case study. Interested in its engagement with its own past, I do not seek to investigate the actions it takes as an institution, for instance, as regards to the politics of repatriation. Instead, I want to explore the whole experience it facilitates as an object in its own right.

This experience begins with …
