A Resilience Metric For Modern Power Distribution Systems, Tyler Bennett Phillips

Boise State University Theses and Dissertations

Modern society has become increasingly reliant on the functioning of critical infrastructure. It is considered so vital that its incapacitation or destruction would have debilitating effects on the global economy, national security, and public health and safety. The electrical power system is uniquely positioned, as it is essential for all other sectors of critical infrastructure to operate as intended. However, it is constantly at risk due to factors such as natural disasters, climate change, aging infrastructure, and cyber threats. Thus, ensuring the efficient and continuous supply of electricity is of utmost importance and the topic of this dissertation.

Coral Reef Restoration In The Tropical West Atlantic Amid The Covid-19 Pandemic, Linden Cheek

USF Tampa Graduate Theses and Dissertations

Climate change is increasing threats to coasts, both from storm surge and sea level rise. Healthy coral reefs provide reduction in storm surges, wave energy, coastal flooding and everyday erosion, and are found across a variety of spatial scales. Given the state of coral reefs worldwide, active Coral Reef Restoration (CRR) in emerging as a necessary component of coastal protection. CRR can be classified as a nature-based solutions (NbS) for coastal protection that also provides a multitude of ecosystem-based services to both humans and other life. Nearly all literature on coral restoration efforts assume a steady-state of human-ecological interactions, but …

A Framework For Adaptive Capacity In Complex Systems, Abdulrahman Alfaqiri

Engineering Management & Systems Engineering Theses & Dissertations

Complex systems are characterized by their high level of inter-connectivity, ambiguity, and emergence. Therefore, a failure in one element of a system (e.g. cyber layer) due to external or internal disturbances can lead to a cascade effect that may influence all elements of the system. Consequently, the complex system will not be able to perform its functional performance. Threats related to complex systems are very dynamic, fast, complex and damage can be severe. Thus, to respond to the dynamic and unpredictable nature of these threats, complex systems need to be highly adaptive to survive and thrive in the face of …

The Resilience Of K-Cores In Graphs, Ricky Laishram

Dissertations - ALL

A k-core of a graph is defined as the maximal subgraph such that all the nodes in the subgraph has at least k neighbors within the subgraph. k-core have been used in a number of applications ranging from anomaly detection and finding influential spreaders in social networks, to studying the robustness of financial and ecological networks.

In our work, we study the effect of missing data (edges or nodes) to the k-core of a graph. In particular, we study three different type of changes. The first type of change is the core structural change, in which the rank order of …

Resilience Engineering: Theory And Practice, Michaela Jones

Civil Engineering ETDs

Civil and environmental engineering works at the interface of humans and the natural environment, making the environment hospitable for people and limiting adverse anthropogenic impacts on the ecosystem. Such socioecological systems are often complex and highly interconnected, and traditional engineering interventions focused on optimizing system elements result in unanticipated consequences. Resilience engineering utilizes a holistic methodology grounded in systems analysis and adaptation. This work broadly explores the concept of resilience engineering and contextualizes the approach using the case study of the Rio Chama. The resilience of the watershed is characterized in terms of its response to both traditional and resilience …

Identificación Y Análisis De Los Factores De Riesgo En El Municipio De Charalá Santander Para El Fortalecimiento De Este Componente En El Esquema De Ordenamiento Territorial, Diego Alejandro Melo Cuellar, Jineth Sofia Pinzón Pico

Ingeniería Ambiental y Sanitaria

El municipio de Charalá se encuentra ubicado en el sur del departamento de Santander, en un contexto montañoso y de alta riqueza hídrica; su vocación económica está enfocada principalmente en la agricultura y ganadería. En los últimos años en el municipio se han presentado situaciones de emergencia desencadenadas por eventos adversos como movimientos en masa, inundaciones e incendios forestales, los cueles han traído consigo impactos económicos, sociales y ambientales. Mediante el presente estudio se identificaron los eventos que presentan mayor amenaza en el municipio y el nivel de vulnerabilidad de la población frente a dichos eventos. La identificación se llevó …

Forecasting Consumer Consumption Behavior Of Water Bottles Using Generlized Linear Model For Supply Chain Resilience, Abdulaziz Alidrees

Open Access Theses & Dissertations

When forecasting the amount of water consumed by individuals at Kuwait's Mubarak Al-Kabeer city Block 8, it is important for any water producing company to tell the amount of water they should produce for its target consumers. After interviewing a couple of residents in this block, it was discovered that they were restricted by being unable to shop for their essentials, including water packs. Data on the amount of water consumption in milliliters for different individuals were collected and recorded. Generic scanners and smartphone scanners were installed in 20 different households that rely on water packs instead of central water …
