Sensitivity Analysis of a Bayesian Network
(The American Society of Mechanical Engineers (ASME), 2018)In a Bayesian network (BN), how a node of interest is affected by the observation at another node is a main concern, especially in backward inference. This challenge necessitates the proposed global sensitivity analysis ... -
The Reliability of a Component Under Several Distributed Cyclic Numbers at the Corresponding Constant Cyclic Stress Levels
(The American Society of Mechanical Engineers (ASME), 2018)The probabilistic stress-number of cycles curve (P-S-N curve) approach is widely accepted for describing the fatigue strengths of materials. It is also a widely accepted fatigue theory for determining the reliability of a ... -
Low-Speed Go-Kart Crash Tests and a Comparison to Activities of Daily Living
(The American Society of Mechanical Engineers (ASME), 2018)Go-karts are a common amusement park feature enjoyed by people of all ages. While intended for racing, contact between go-karts does occur. To investigate and quantify the accelerations and forces which result from contact, ... -
Hybrid Probabilistic–Possibilistic Treatment of Uncertainty in Building Energy Models: A Case Study of Sizing Peak Cooling Loads
(The American Society of Mechanical Engineers (ASME), 2018)Optimal sizing of peak loads has proven to be an important factor affecting the overall energy consumption of heating ventilation and air-conditioning (HVAC) systems. Uncertainty quantification of peak loads enables optimal ... -
Generic Approach for Risk Assessment of Offshore Piping Subjected to Vibration Induced Fatigue
(The American Society of Mechanical Engineers (ASME), 2018)Vibration induced fatigue (VIF) failure of topside piping is one of the most common causes of the hydrocarbon release on offshore oil and gas platforms operating in the North Sea region. An effective inspection plan for ... -
