Examining Sample Rate, Sample Time, and Test Replication for Reducing Uncertainty in Steady Timewise Experiments
(The American Society of Mechanical Engineers (ASME), 2016)This paper presents the ways that sample rate, sample time, and number of test replications can affect the random uncertainty in a measurement. Typical steady timewise experiments seek the average values of measured ... -
Filtering Algorithm for Real Eigenvalue Bounds of Interval and Fuzzy Generalized Eigenvalue Problems
(The American Society of Mechanical Engineers (ASME), 2016)This paper deals with an interval and fuzzy generalized eigenvalue problem involving uncertain parameters. Based on a sufficient regularity condition for intervals, an interval filtering eigenvalue procedure for generalized ... -
A Fuzzy Logic Approach in the Definition of Risk Acceptance Boundaries in Occupational Safety and Health
(The American Society of Mechanical Engineers (ASME), 2016)Organizations need to make decisions about risk acceptance, to decide about the need of risk-reducing measures. In this process, the personal judgments of occupational safety and health (OSH) practitioners have great ... -
Semi-Analytic Probability Density Function for System Uncertainty
(The American Society of Mechanical Engineers (ASME), 2016)In general, the behavior of science and engineering is predicted based on nonlinear math models. Imprecise knowledge of the model parameters alters the system response from the assumed nominal model data. One proposes an ... -

Experimental Time-Domain Vibration-Based Fault Diagnosis of Centrifugal Pumps Using Support Vector Machine
(The American Society of Mechanical Engineers (ASME), 2017)When the hydraulic flow path is incompatible with the physical contours of the centrifugal pump (CP), flow instabilities occur. A prolonged operation in the flow-instability region may result in severe damages of the CP ... -
Reliability Optimization Allocation Method for Multifunction Systems With Multistate Units Based on Goal-Oriented Methodology
(The American Society of Mechanical Engineers (ASME), 2017)This paper proposes a new reliability optimization allocation for multifunction systems with multistate units based on goal-oriented (GO) methodology. First, this optimization allocation method is expounded in terms of ... -
On Social Value of Risk Information in Risk Communication
(The American Society of Mechanical Engineers (ASME), 2017)The conventional research of risk communication centers on how scientific community can improve trust and credibility in public perception, enhance public understanding of risks, and change public behaviors to conform to ... -
A Mixed-Kernel-Based Support Vector Regression Model for Automotive Body Design Optimization Under Uncertainty
(The American Society of Mechanical Engineers (ASME), 2017)Finite element (FE) models are commonly used for automotive body design. However, even with increasing speed of computers, the FE-based simulation models are still too time-consuming when the models are complex. To improve ... -
Simulation and Experiment of Mass Evacuation to a Tsunami Evacuation Tower
(The American Society of Mechanical Engineers (ASME), 2017)A three-dimensional (3D) mass evacuation simulation using precise kinematic digital human (KDH) models and an experimental study are discussed. The flooding associated with the large tsunami caused by the Great East Japan ... -
Design and Testing of a Crashworthy Landing Gear
(The American Society of Mechanical Engineers (ASME), 2017)The development of a crashworthy landing gear is presented based on the civil regulations and the military specifications. For this, two representative crashworthy requirements are applied to helicopter landing gear design: ... -
Predictive Abnormal Events Analysis Using Continuous Bayesian Network
(The American Society of Mechanical Engineers (ASME), 2017)The reliable prediction and diagnosis of abnormal events provide much needed guidance for risk management. The traditional Bayesian network (traditional BN) has been used to dynamically predict and diagnose abnormal events. ... -
Analytical Solution Strategy for Building Energy Dynamics With Stochastic Thermal Gains and External Temperature
(The American Society of Mechanical Engineers (ASME), 2017)Energy dynamics in buildings are inherently stochastic in nature due to random fluctuations from various factors such as heat gain (including the solar) and ambient temperature. This paper proposes a theoretical framework ... -
Determining Probability of Importance of Features in a Sketch
(The American Society of Mechanical Engineers (ASME), 2017)Sketches can be categorized as personal, shared, persuasive, and handover sketches. Depending on each category, their level of ambiguity also varies. The applications of sketches include conceptual design, eliciting user ... -
Assessment of the Pitting Corrosion Degradation Lifetime: A Case Study of Boiler Tubes
