RISOptimal Sectional Design of Frame Structures Using Geometric Programming
Publisher: American Society of Civil Engineers
Abstract: Taking all cross‐sectional sizes as design variables, the paper presents a method that transforms the original optimal design model of frame structures to standard signomial geometric programming (SGP) through the generalized ...
Zero Potential Vorticity Envelopes for the Zonal-Mean Velocity of the Venus/Titan Atmospheres
Publisher: American Meteorological Society
Abstract: The diagnostic analysis of numerical simulations of the Venus/Titan wind regime reveals an overlooked constraint upon the latitudinal structure of their zonal-mean angular momentum. The numerical experiments, as well as ...
Study of Enhancement Coefficient of Washboard Road of Automobile Proving Ground
Publisher: American Society of Civil Engineers
Abstract: By calculating the fatigue life of the sample vehicle and applying calculation method of road enhancement coefficient, the enhancement coefficient of washboard road was calculated and studied. Vehicle reliability test on ...
Fuzzy Comprehensive Evaluation of the Adaptability of an Expressway System
Publisher: American Society of Civil Engineers
Abstract: The evaluation of the adaptability of expressway systems is a multiple-objective comprehensive evaluation problem. First, the concept of the adaptability of an expressway is defined, the 2-level index system to influencing ...
Cluster Analysis of Risk Factors from Near-Miss and Accident Reports in Tunneling Excavation
Publisher: American Society of Civil Engineers
Abstract: Many inherently risky industries improve their safety management by learning from near-miss incidents. The construction industry is starting to manage near-miss incidents for improving safety, and several studies have been ...
Emissions From Oxy-Combustion of Raw and Torrefied Biomass
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work assesses the evolution of acid gases from raw and torrefied biomass (distiller’s dried grains with solubles and rice husk) combustion in conventional (air) and simulated oxy-combustion (oxygen/carbon dioxide) ...
Collagen Fibril Orientation in Tissue Specimens From Atherosclerotic Plaque Explored Using Small Angle X-Ray Scattering
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Atherosclerotic plaques can gradually develop in certain arteries. Disruption of fibrous tissue in plaques can result in plaque rupture and thromboembolism, leading to heart attacks and strokes. Collagen fibrils are important ...
Research on the Obtainment of Topography Parameters by Rough Surface Simulation With Fast Fourier Transform
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Asperity radius of curvature and asperity density, which are generally obtained from rough surface simulation with fast Fourier transform (FFT), are the two essential parameters for statistical contact model. In simulation, ...
Analysis of Car Impact Signal Based on Wavelet Transform Theory
Publisher: American Society of Civil Engineers
Abstract: Nonlinear and non-stability car impact signal processing method was studied, and time-frequency for multi-resolution was analyzed. The resolution “auto-zoom” was analyzed and time-frequency was allocated for complex ...
Effects of Air Flowrate on the Combustion and Emissions of Blended Corn Straw and Pinewood Wastes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This research investigated the effects of the specific primary (under-fire) air flowrate (m˙air) on the combustion behavior of a 50–50 wt % blend of raw corn straw (CS) and raw pinewood wastes in a fixed-bed reactor. This ...
