BACKGROUND The important purpose of a powered gait orthosis is to provide active joint movement for patients with spinal cord injury. OBJECTIVES The aim of this study was to clarify the effect of a powered gait orthosis on the kinematics and temporal-spatial parameters in paraplegics with spinal cord injury. STUDY DESIGN Quasi-experimental. METHODS Four spinal cord injury individuals expe...

The general goal of power management (PM) is to achieve optimal system performance while meeting power constraints. Minimizing the energy consumption is mostly not sufficient. Especially power management policies for battery-powered and RFpowered devices require a deep understanding of the supplies’ electrical characteristics. Thus, battery-aware PM aims to efficiently utilize the battery by re...

A powered longwall mining system comprises three basic machines: a shearer, scraper (longwall) conveyor, and roof support. The support as component of complex has two functions. It protects the working from rocks that fall to area where machines people work transports devices in operation proceeds further into seam by means hydraulic actuators are adequately connected controlled or electro-hydr...

The origin of avian flight is a classic macroevolutionary transition with research spanning over a century. Two competing models explaining this locomotory transition have been discussed for decades: ground up versus trees down. Although it is impossible to directly test either of these theories, it is possible to test one of the requirements for the trees-down model, that of an arboreal paravi...
