Anomaly Detection for Control Centers
The control center is a critical location in the power system infrastructure. Decisions regarding the power system’s operation and control are often made from the control center. These control actions are made possible through SCADA communication. This capability however makes the power system …

Constricted Urban Planning: Investigating the Site and Suitability of Low-Income Housing in Fairfax County, Virginia
… To do so, this research identifies and explains location amenities and neighborhood characteristics that maximize the success of low-income housing programs for low-income households, and explores how suburban landscapes constrict the ability of policymakers and planners to incorporate such …

Behavior of Wind Turbine Towers and Blades Under Tornado Wind Fields
… been conducted with the goal of determining the critical tornado wind field for wind turbines considering different tornado structures. The methodology depends on identifying the critical location of the tornado that will cause peak straining actions on the tower and blades, and the optimal pitch …

Assessing glacier retreat and landform production at the ‘debris-charged’ snout of Kvíárjökull, Iceland
Iceland is a critical location for the study of glacier fluctuations and landform production in response to climate change due to its diverse glacial legacy and its archive of aerial photographs that provide accurately dated records of glacier retreat and landform evolution from 1945. This study …

Variation and modernity in Middle Stone Age landscape use in the Western and Northern Cape, South Africa
Southern Africa is a critical location for understanding the origins of modern human behaviour in the Middle Stone Age (MSA), about 300 to 40 ka. Current evidence from excavated, often coastal, cave sites indicates the emergence of complex technological, social and symbolic behaviours at least 100 …

Optimal Resource Allocation Strategies to Protect Network-structured Systems
Protection of critical national infrastructure has received significant attention in the past recent years. As a result, researchers have developed methods to preserve and maintain critical infrastructure systems and minimize their vulnerability to disasters and disruptions. However, these models …

Effect of ply drop-offs on the strength of graphite-epoxy laminates
… failure criterion predicts this as the critical location in the finite element model as well. However, the tensile interlaminar criterion underestimates the failure initiation load. The cause for this may be due to the inaccuracies in the modeling of the ply drop-off geometry in the …

Implementation of the Security-Dependability Adaptive Voting Scheme
As the world moves further into the 21st century, the electricity demand worldwide continues to rapidly grow. The power systems that supply this growing demand continue to be pushed closer to their limits. When those limits are exceeded, system blackouts occur that have massive societal and …

Interrogative Design as a Means for Confronting Hostile Architecture
… and social control. Here, the body is seen as a critical location of our connection and expression of our sociality. Homelessness is a multifaceted concept, and people neglect the vulnerability associated with a population that is disproportionally impacted by social, economic, political and …

A variational framework for multi-scale defect modeling in strained electronics and processing of composite materials
… of defects within the material parts at critical location during processing. This dissertation presents a deterministic defect modeling framework based on a system of variationally consistent formulations that allow for the modeling of the material processing stage and incorporate …

Influence of calcium-(alumino)-silicate-hydrate nanostructure on viscoelastic behavior
… time-dependent behavior indicate that this is a critical location in the C-(A)-S-H nanostructure with respect to viscoelasticity. Multiple methods of nanoindentation analysis were applied to synthesized C-(A)-S-H for the first time. Stress relaxation and dynamic nanoindentation measurements have …

Materials characterization and structural design of ceramic micro turbomachinery
… element method. It was found that the stress critical location is located at the root of the turbine blade trailing edge. In order to reduce both stress and deflection levels, various structural redesign approaches were proposed. The finite element stress analysis and the fracture strength …

Analysis and Design of Variable Stiffness Composite Cylinders
… reveal that even though slight increases in the critical loads can be produced for designs with an arbitrary variation of the fiber orientation angle, the improvements are not significant when compared to traditional design techniques that utilize ring stiffeners and frames. The second problem …
