In bilateral telemanipulation scenarios the human hand/arm is usually put in correspondence with a robotic hand/arm system. The kinematic structure of the human hand and of the robotic hand are typically different requiring algorithm to map human motion on the robot workspace. At the same time, the force measured at the robotic side cannot usually be displayed in the same point on the human han...

In this study, response surface methodology (RSM) based on central composite design (CCD) was applied for investigation of the effects of ultrasonic waves, temperature and solvent concentration on viscosity reduction of residue fuel oil (RFO). Ultrasonic irradiation was employed at low frequency of 24 kHz and power of 280 W. The results showed that the combination of ultrasonic waves and solven...

In this paper, the extended kalman filter based direct kinematic method was proposed to calculate the real-time end-effector position in a Stewart platform. A noise analysis based on the data transmission is proposed firstly, in which the size order of time domain noises is concerned. Then non-linear kinematic model and numerical method for Stewart platform are presented respectively. Later, an...

‎In this paper‎, ‎we introduce $alpha$-$psi$-contractive mapping in partially ordered sets and construct fixed point theorems to solve a first-order ordinary differential equation by existence of its lower solution.

Abstract In this paper a selected type of elasto-viscoplastic constitutive equations is considered. The viscoplastic model which was proposed by Marquis generalized allowing multiple terms describing the isotropic and kinematic hardening. Furthermore, presented formulation enables one to use an arbitrary equivalent plastic strain function describe hardening behavior. What more, backstress evolu...
