Abstract: Metallic porous structures have proved to be effective in enhancing heat transfer due to the inherent characteristics such as high specific surface area and large pore densities. In this study, ...

Abstract: This paper demonstrates that the Coulomb friction, the most difficult part of friction to be compensated because of its discontinuity with respect to the velocity, can be precisely compensated without either its mathematical ...

Abstract: In this paper, an adaptive backstepping controller, which can attenuate external disturbance, is proposed for flight vehicle attitude control subject to amplitude and rate saturations of the elevator. First, the elevator ...

Abstract: A mixed FEM–crushable discrete-element method (DEM) nested scheme in the frame of second-order computational homogenization for granular materials was proposed. The particle breakage followed by the discontinuity and ...

Abstract: Restoring human grasp functions by prosthesis is a long-standing challenge in robotics research. Aiming at prosthetic applications, this paper presents a novel anthropomorphic multi-grasp hand design. The hand is driven ...

Abstract: Due to the ductile properties of large-rupture-strain fiber-reinforced polymer (LRS-FRP) laminates and their confined concrete, the failure patterns and ultimate deformation capacities of LRS-FRP-strengthened reinforced ...

Abstract: Driving system parameter optimization (DSPO) is an important approach to improve robots' dynamic performances such as acceleration capacity, load carrying capacity, and operation stability. To achieve better dynamic ...

Abstract: The sit-to-stand (STS) movement is a common activity essential for independence and mobility. Traditional methods for assessing STS often involve costly laboratory equipment, limiting their accessibility. This study ...
