The values underpinning Iceland's food system risk : implications for resilience planning
… change threatens to exacerbate these food system weaknesses. Yet Iceland has no contingency plan, and adaptation measures are absent from national climate change reports. While this gap could be perceived as negligence, to do so assumes a universalistic framework for risk and resilience -- …

Critical Substation Risk Assessment and Mitigation
Substations are joints in the power system that represent nodes that are vital to stable and reliable operation of the power system. They contrast the rest of the power system in that they are a dense combination of critical components causing all of them to be simultaneously vulnerable to one …

Probabilistic risk assessment of system-level radiation effects
System-level radiation effects analysis is performed using a time-dependent Probabilistic Risk Assessment (PRA) methodology. Data-driven models for the expected behavior of radiation-sensitive parts are instanced in a system model for Fault Tree Analysis (FTA). The system model is then solved using …

Electricity market integration of stochastic renewable resources : efficiency and risk tradeoffs
… can have significant effects on efficiency and risk. This research analyzes how producers respond to market mechanisms intended to improve forecasting and long-term siting decisions. This thesis characterizes producer equilibrium strategies in competitive short term energy markets by examining …

Localization Performance Improvement of a Low-Resolution Robotic System using an Electro-Permanent Magnetic Interface and an Ensemble Kalman Filter
… occurs. To remove the human element, the robot system then must account for safety as well. Thus, system risk can easily overwhelm project costs. This thesis proposes a combination of hardware and state estimation solutions to improve the feasibility of low-fidelity and low-resolution robots for …

Implementation of Design Failure Modes and Effects Analysis for Hybrid Vehicle Systems
… the current methods used to analyze and evaluate risk with the new hybrid technologies to ensure the continued customer satisfaction and safety while meeting new government and agency standards. The primary goal of this work is to maintain consistent definitions, standards, and protocols for risk …

Designing Resilient Manufacturing Systems In the Presence of Change
… to redesign and enhance their operational systems. The implications of such changes within a complex system such as manufacturing and the supply chain can be very challenging. In particular, where the number of system elements and their connections result in a high level of complexity, the …

Contributions to the foundations of a safety case for the use of GNSS in railway environments
… safety integrity values and the possibility of system risk, leading to the formation of a structured safety case. Three main data sets from electrified, rural and urban rail environments have been collected using dual frequency geodetic receivers in order to enable analysis of multipath effects …

Dynamic Analysis of Levee Infrastructure Failure Risk: A Framework for Enhanced Critical Infrastructure Management
Current models that assess infrastructure failure risk are "linear," and therefore, only consider the direct influence attributed to each factor that defines risk. These models do not consider the undeniable relationships that exist among these parameters. In reality, factors that define risk are …

Banki működési kockázat és intézményméret = Operational risk of banks and firm size
… In my thesis, I analysed the operational risks and risk management methods related to the activity of banks. By operational risk we mean the risk of loss resulting from inadequate or failed operation of people, systems, and processes or from external events. Firstly in a stylised model …

Perceptions of risk in increasingly capital-intensive electricity grids : measuring the impacts of accurate cost of capital representation on investment planning for future energy systems
… grid is experiencing unprecedented change as the system continues a path toward a more diversified and decarbonized generation mix, with increased investment in wind, solar, storage and other energy transition technologies. Concurrently, market structures continue their evolution away from highly …

A Cross-Cultural Examination: Effects of Reward Systems and Cultures on Low Severity Risk-Taking Behavior in Construction
… objective was to identify the effects of reward systems (rewards and a penalty) on risk-taking behavior and performance (quality and time) of construction workers from different cultures (American, Asian, and Latin American cultures). This research used the sociotechnical system as the …
