RISCompensation and Estimation of Friction by Using On Line Input Estimation Algorithm
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a compensation method of nonlinear friction using online input estimation (IE) method is developed. To illustrate the validity and performance of the proposed algorithm applied to positioning system, comparisons ...
Enhanced Tribological Performance of UHMWPE Composites Reinforced With Wollastonite: Biocompatibility and Wear Behavior
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ultra-high molecular weight polyethylene (UHMWPE) is often limited by poor tribological properties in artificial joints, leading to high wear-rates compared to metals and ceramics. This study explores the use of wollastonite, ...
Comparison of Monthly Temperature Extremes Simulated by CMIP3 and CMIP5 Models
Publisher: American Meteorological Society
Abstract: he extreme monthly-mean temperatures simulated by 28 models in the fifth phase of the Coupled Model Intercomparison Project (CMIP5) are evaluated and compared with those from 24 models in the third phase of the Coupled ...
Effect of Solid Carburization on the Tribological Behaviors of Ti13Nb13Zr Alloy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Due to its high mechanical strength, exceptional biocompatibility, low elastic modulus, and superior corrosion resistance, Ti13Nb13Zr alloy is one of the potential candidates for implanted joints. However, the poor ...
Probability Distribution of Precipitation Extremes for Weather Index–Based Insurance in the Zhujiang River Basin, South China
Publisher: American Meteorological Society
Abstract: n a changing climate, understanding the frequency of weather extremes is crucial to improving the management of the associated risks. The concept of weather index?based insurance is introduced as a new approach in weather ...
A Novel Transformable Leg-Wheel Mechanism
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a novel transformable leg-wheel mechanism is proposed. It has three active joints, among which the hip roll joint is directly driven, the hip pitch joint is driven by gear transmission, and the knee joint ...
