Objectives: The purpose of the present study was to show that the design of a neuroprosthesis for unsupported (arm-free) standing is feasible. We review findings suggesting that a closed-loop controlled functional electrical stimulation (FES) system should be able to facilitate arm-free quiet standing in individuals with spinal cord injury (SCI). Particularly, this manuscript identifies: 1) a c...

In this paper, a passive bilateral control law is proposed for a teleoperator consisting of a pair of n-DOF nonlinear robotic systems. The control law ensures energetic passivity of the closed-loop teleoperator with power scaling, coordinates motions of the master and slave robots, and installs useful task-specific dynamics for inertia scaling, motion guidance and obstacle avoidance. Consequent...

Mechanical vibrations adversely affect mechanical components, and in the worst case, lead to serious accidents by breaking themselves. To suppress vibrations, various studies have been conducted on vibration isolation, suppression, resistance. In addition, technologies actively rapidly developed recent years, it has reported that can be suppressed with higher performance. However, these mostly ...

We present the extraction of temperature by analyzing charged particle transverse momentum spectra in lead–lead (Pb–Pb) and proton–proton (pp) collisions at LHC energies from ALICE Collaboration using Color String Percolation Model (CSPM). From measured energy density $${\varvec{\varepsilon }}$$ T dimensionless quantity }/}T^{4}$$ is obtained to get degrees freedom (DOF), }}/T^{4} = \hbox {DOF}...

When the finite element model of a complex structure is partitioned into substructures in order to enable component mode synthesis (CMS), there may be a large number of degrees of freedom (DOF) on the interface between components. In such a case, the constraint-mode-related coordinate transformation at the substructure analysis stage becomes computationally expensive, and the CMS model may be c...

A novel model-based controller for 6 degree-of-freedom (DOF) hydraulic driven parallel manipulator considering the nonlinear characteristic of hydraulic systems-proportional plus derivative with dynamic gravity compensation controller is presented, in order to improve control performance and eliminate steady state errors. In this paper, 6-DOF parallel manipulator is described as multi-rigid-bod...
