RISClosed-Loop Analysis in Semantic Tolerance Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A semantic tolerance modeling scheme based on generalized intervals was recently proposed to allow for embedding more tolerancing intents in specifications with a combination of numerical intervals ...
Semantic Tolerance Modeling With Generalized Intervals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A significant amount of research has been performed to explore the mathematical basis for dimensional and geometric tolerance representation, analysis, and synthesis. However, tolerancing semantics ...
Multiscale Uncertainty Quantification Based on a Generalized Hidden Markov Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Variability is the inherent randomness in systems, whereas incertitude is due to lack of knowledge. In this paper, a generalized hidden Markov model (GHMM) is proposed to quantify aleatory and ...
Assessing Disaster Impact in Real Time: Data-Driven System Integrating Humans, Hazards, and the Built Environment
Publisher: ASCE
Abstract: Current disaster impact assessments are conducted within days after an event and usually with limited workforce and resources. Although many recognize the valuable information attainable in this way, the evidence is likely ...
Spatial Stress of the Pier–Girder Rigid Region of a Continuous Rigid-Frame Bridge with V-Shaped Piers in Two Directions
Publisher: ASCE
Abstract: The pier–girder rigid region of continuous rigid-frame bridges with V-shaped piers has a complex spatial stress state because of its special structure and complex boundary condition. However, using the beam–column element ...
Numerical Simulation of High-Strength Concrete Creep under Cyclic Load
Publisher: ASCE
Abstract: To study the development of high-strength concrete creep under cyclic load as well as the distribution of moisture flow velocity, pore pressure, and equivalent stress, a concrete creep model based on a porous medium was ...
Preparing Urban Curbside for Increasing Mobility-on-Demand Using Data-Driven Agent-Based Simulation: Case Study of City of Gainesville, Florida
Publisher: ASCE
Abstract: Cities in many countries are witnessing an era of transformative innovations in vehicular technologies and mobility-on-demand (MoD) services in the context of global initiatives of smart and connected cities. However, ...
Adaptive Control of an Aerospace Electrohydrostatic Actuator with a Constant-Torque Variable-Displacement Pump
Publisher: ASCE
Abstract: An electrohydrostatic actuator (EHA) system is one of the key components of electric aircraft flight controls. The EHA system with fixed pump displacement and variable motor (EHA-FPVM) is widely used because of its simple ...
Calculation Model for Multiple Breaking Waves and Wave-Induced Currents on Very Gentle Beaches
Publisher: ASCE
Abstract: Multiple wave breaking and wave-recovery processes are typical phenomena of wave motions observed on very gentle coastal beaches and have not been accounted for in previous models for the calculation of wave height and ...
When Climate Mitigation Meets the Needs of Adaptation: Closing the Resilience Gap for EV Charging Services in Hurricane-Prone Areas
Publisher: American Society of Civil Engineers
Abstract: Transportation electrification aims to mitigate climate change but will also introduce challenges to adaptation planning and management of infrastructure and facilities. Concurrently, these challenges can be amplified by ...
