RISFault Diagnosis of Bearings Using Recurrences and Artificial Intelligence Techniques
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Rolling element bearings are one of the most common mechanical components used in a wide variety of rotating systems. The performance of these systems is closely associated with the health of bearings. In this study, a ...
Incorporating Economies of Scale in Top-Down Pavement Management Systems
Publisher: American Society of Civil Engineers
Abstract: Top-down maintenance, rehabilitation, and reconstruction (MR&R) policies typically are modeled using Markov decision processes (MDPs). Within this framework, the total agency costs are assumed to increase linearly with ...
Impact of Team Characteristics in Learning Sustainable Built Environment Practices
Publisher: American Society of Civil Engineers
Abstract: The existing architecture, engineering, and construction (AEC) industry has a fragmented nature in which each team member works in isolation away from a whole-systems thinking. It is a challenge to produce sustainable ...
Simultaneous Network Optimization Approach for Pavement Management Systems
Publisher: American Society of Civil Engineers
Abstract: In the context of sequential decision making under uncertainty, the Markov decision process (MDP) is a widely used mathematical framework. The MDP-based approaches in the infrastructure management literature can be broadly ...
Medical Devices for Low- and Middle-Income Countries: A Review and Directions for Development
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The development of diagnostics and medical devices has historically been concentrated in high-income countries, despite a significant need to expand healthcare services to low- and middle-income countries (LMIC). Poor ...
A Posteriori Error Analysis of Defect Correction Method for Singular Perturbation Problems With Discontinuous Coefficient and Point Source
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper presents a defect correction method to solve singularly perturbed problems with discontinuous coefficient and point source. The method combines an inexpensive, lower-order stable, upwind difference scheme and a ...
Machine-Learning Application for Fast 3-Phase Black Oil Reservoir Simulation
Publisher: American Society of Civil Engineers
Abstract: AbstractReservoir simulation is essential for field development and well planning through
the estimation of pressure, saturation distribution, and production rate decline prediction.
One of the primary objectives of the ...
Schlieren Image Velocimetry and Modal Decomposition Study of Preheated Isothermal Flow From a Generic Multi-Swirl Burner
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study presents an experimental investigation into the turbulent flow characteristics of an unconfined counter-rotating dual swirl burner under external acoustic excitation. Utilizing Schlieren image velocimetry (SIV), ...
Adaptive Mesh Generation and a Higher-Order Hybrid Approximation to Time-Dependent Singularly Perturbed Reaction–Diffusion Equations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. This paper introduces a novel hybrid difference approximation for solving time-dependent reaction–diffusion problems with shifts and integral boundary conditions. The problem is singularly perturbed, and its ...
