RISAdaptive Global Stability of Nonlinear Pure-Feedback Systems With Unknown Time-Varying Delays
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates the backstepping control problem for nonlinear pure-feedback systems with time-varying delays. A virtual controller is designed to counteract the effects caused by the state perturbation of time ...
An Experimental Study on Strain Hardening of Amorphous Thermosets: Effect of Temperature, Strain Rate, and Network Density
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we present an experimental study on strain hardening of amorphous thermosets. A series of amorphous polymers is synthesized with similar glass transition regions and different network densities. Uniaxial ...
Inhibition Effect of Thermally-Induced Fire in 21,700 Lithium-Ion Battery With Low-Pressure Twin-Fluid Water Mist
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The fire hazard of lithium-ion batteries (LIBs) poses a serious threat to their transportation and use. The purpose of this study is to investigate the efficiency of low-pressure twin-fluid water mist (TFWM) on suppressing ...
Design of a Family of Ultra-Precision Linear Motion Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The parasitic motion of a parallel four-bar mechanism (PFBM) is undesirable for designers. In this paper, the rigid joints in PFBM are replaced with their flexural counterparts, and the center ...
Numerical Simulation of Load Bearing Capacity of Corroded Reinforced Concrete Beam after Cyclic Loading
Publisher: American Society of Civil Engineers
Abstract: The numerical simulation analysis of the static load bearing capacity of a corroded reinforced concrete (RC) beam after being subjected several times to fatigue load is conducted using the ABAQUS software. Parameters, such ...
Semianalytical Solution for General Active Earth Pressure Considering the Coupling and Dilatation
Publisher: ASCE
Abstract: Rankine pressure involves the special case of active earth pressure and merely considers the influence of the internal friction angle; however, the analytical solution for the general case involving a rough retaining wall, ...
Analytical Solution for Axisymmetric Active Earth Pressure Based on the Characteristics Method considering Orthoradial Geometric Condition
Publisher: American Society of Civil Engineers
Abstract: The current analytical solutions for axisymmetric active earth pressure are based on certain hypothetical relationships between the circumferential stress, the average stress of the meridional plane, and the main shear ...
Urbanization Effects on Observed Surface Air Temperature Trends in North China
Publisher: American Meteorological Society
Abstract: A dataset of 282 meteorological stations including all of the ordinary and national basic/reference surface stations of north China is used to analyze the urbanization effect on surface air temperature trends. These stations ...
