There is an impedance mismatch between message-passing concurrency and virtual machines, such as the JVM. VMs usually map their threads to heavyweight OS processes. Without a lightweight process abstraction, users are often forced to write parts of concurrent applications in an event-driven style which obscures control flow, and increases the burden on the programmer. In this paper we show how ...

Virtual decomposition control is applied to control a KUKA 361 six-joint industrial robot performing hybrid tasks with a rigid unilateral constraint. In order to accommodate motion/force control, the required velocity is re-designed by introducing filtered contact forces in full control dimensions, which makes the controlled robot behave as hybrid controlled for a known contact geometry and imp...

In this paper, power-sharing management control on an AC islanded microgrid is investigated to achieve accurate reactive power sharing. The droop method primarily used manage the active and sharing among DGs in microgrid. However, line impedance mismatch causes unbalanced As a solution consensus-based adaptive virtual controller proposed, where consensus algorithm set mismatch; then correction ...

Power electronics converters are utilized for interconnecting distributed energy storage systems into the grid. These can support stability of power system under abnormal grid conditions. In this article, a new coordinated voltage-frequency strategy is proposed considering reactance-to-resistance ratio impedance. Unlike conventional schemes transmission grids, where voltage and frequency decoup...

electrochemical impedance spectroscopy (eis) is a suitable and powerful diagnostic testing method for fuel cells (fcs) since it is non-destructive and provides useful information about fc performance and its components. in this study, for the first time, a 500w cascade type 4 cells stack with integrated humidifier, water separator and internal manifolds was designed, fabricated and tested. the ...

A high performance six degree-of-freedom magnetic levitation haptic interface device has been integrated with a physically-based dynamic rigid-body simulation to enable realistic user interaction in real time with a 3-D dynamic virtual environment. The user grasps the levitated handle of the device to manipulate a virtual tool in the simulated environment and feels its force and motion response...
