When arm movements are perturbed by a load, how does the nervous system adjust control signals to reduce error? While it has been shown that the nervous system is capable of compensating for the effects of limb dynamics and external forces, the strategies used to adapt to novel loads are not well understood. We used a robotic exoskeleton [kinesiological instrument for normal and altered reachin...

background: in general, measurements of solar ultraviolet (uv) radiation are related to horizontal surfaces. while the hu­mans walking and standing outdoors expose to the natural solar uv radiation, their eyes, cheeks, extremities, trunks, or many other anatomical sites are close to vertical plane and random orient to different directions. in this study, we character­ized the diurnal variations...

The low order Taylor’s series expansion was employed in this study to estimate the reliability indices of failure criteria for reliability-based design optimization a linear static structure subjected random loads and boundary conditions. By taking advantage superposition principle, only few analyses unit-loads are needed through entire process produce acceptable results. Two structural example...

A statistical model for the prediction of radiated susceptibility (RS) of unshielded twisted wire pairs (TWPs) running above ground, and illuminated by a random field in a complex electromagnetic environment, is presented. The incident field is modelled as a superposition of plane waves with random amplitude, phase, and polarization. The expected value of the average power of RS noise at termin...

The classic S-plane control method combines PD structure with fuzzy theory, the advantages of a simple and fewer parameters to be adjusted. It has been proved as practical in an autonomous underwater vehicle (AUV) motion at low medium speeds, but it takes no account situational static load varying hydrodynamic forces which influence quality even result “dolphin effect” time high-speed movement....
