The load-sensing system has for a long time been the most energy efficient hydraulic widely used mobile machines. When replacing combustion engine drive with an electric battery as source incentive using more systems arise. Some promising examples of are independent metering systems, pump controlled and open flow control systems. Before getting to deeply involved in specific design, investigati...

The action of ketamine upon spontaneously active and electrically driven Purkinje fibres of the moderator band of the pig heart has been studied using a floating microelectrode technique. Ketamine hydrochloride altered the transmembrane potential in a dose-related and reversible manner. Concentrations of 1X 10M were subthreshold whereas 5 X 10'M and 1X 10~M slowed the frequency and increased th...

Almost all present control strategies for electrically-driven robots are under the rigid robot assumption. Few results can be found for the control of electrically driven robots with joint flexibility. This is because the presence of the joint flexibility greatly increases the complexity of the system dynamics. What is worse is when some system dynamics are not available and a good performance ...

Abstract n this paper, a Robust Integral of the Sign Error (RISE) feedback controller is designed for a Rigid-Link Electrically Driven (RLED) robot manipulator actuated by direct current DC motor in presence of parametric uncertainties and additive disturbances. RISE feedback with implicitly learning capability is a continuous control method based on the Lyapunov stability analysis to compensat...

A planar biomechanical model of a human leg has been developed to investigate automatic control strategies for artificially stimulated muscle using electrical stimulation (ES). The model comprises the nonlinear multiplicative model of the muscles, tendons and two body segments (thigh and shank-foot complex), that is, the hip and the knee. Flexor and extensor muscles are included for each joint....

We study the electrically driven spreading of dielectric liquid films in wedge-shaped gaps across which a potential difference is applied. Our experiments are in a little-studied regime where, throughout the dynamics, the electrical relaxation time is long compared to the time for charge to be convected by the fluid motion. We observe that at a critical normal electric field the hump-shaped lea...

We suggest and demonstrate via large scale numerical simulations an electrically operated spin-wave inducer based on composite multiferroic junctions. Specifically, we consider an interfacially coupled ferromagnetic/ferroelectric structure that emits controllably spin waves in the ferromagnets if the ferroelectric polarization is poled by an external electric field. The roles of geometry and ma...

In this work, we demonstrate abrupt, reversible switching of resistance in 1T-TaS2 using dc and pulsed sources, corresponding to an insulator-metal transition between the insulating Mott and equilibrium metallic states. This transition occurs at a constant critical resistivity of 7 mohm-cm regardless of temperature or bias conditions and the transition time is significantly smaller than abrupt ...
