Abstract: An analysis of a target tracking mechanical system subject to random base excitations is presented in this paper. Sliding mode controls are proposed to minimize the random error of target ...

Abstract: In the conventional design of a spillway invert and flow bucket, circular, elliptic, and parabolic curves are generally used to connect straight boundaries. Because of the abrupt change in curvature at tangency points, ...

Abstract: The main difficulty in running a rigid-plastic finite element program for metal forming analysis on a personal computer lies in the lengthy computation, typical of non-linear problems. To make ...

Abstract: It has long been discussed whether Terzaghi’s expression for effective stress holds true for all saturated soils. To examine the physical basis of the effective stress expression, a new mechanical model is proposed. According ...

Abstract: Understanding capillary water absorption in concrete is of major significance for the durability assessment of concrete structures, particularly when cracks are present. The paper develops a three-dimensional (3D) ...

Abstract: To advance our knowledge of the response of midlatitude westerlies to various external forcings, we investigate the meridional shift of midlatitude westerlies over arid central Asia (ACA) during the past 21 000 years, which ...

Abstract: Failure accidents of transmission lines due to excessive wind-induced displacements pose a serious threat to the operational stability and security of the electric power grid. A Bayesian approach is proposed to assess the ...

Abstract: The goal of this paper is to reveal the influence of temperatures on the triaxial strength of asphalt mixtures. The triaxial compression and triaxial tensile tests, as well as plane tensile and compression/axial tensile ...
