Due to the increased functionality in today’s portable devices, battery life and energy consumption continue to be a major concern for both designers and users. Unfortunately battery technology is not keeping pace with the energy requirements of these devices and therefore energy-efficient hardware design techniques, software optimization, energy management, and the design of efficient communic...

This paper investigates the operation of each power conversion system (PCS) for efficient energy management systems (EMSs) microgrids (MGs). When MGs are linked to renewable sources (RESs), reduction in efficiency can be minimized. Furthermore, storage (ESSs) utilized manage surplus RESs. Thus, present work presents a method minimize use existing grid and increase utilization rate generated thr...

ABSTRACT This work seeks to determinate whether the transient simulation on two PCs employing diakoptics to partition short cables is better, flop-wise, than using one PC─even for a small network. A methodology for the parallel simulation of a shipboard power system coupled by short lines is presented. Loop analysis, suggested by the nature of ungrounded power systems, is applied to formulate a...

Medical accelerators require arc-free operation. Due to high-field emission, arcing and outgassing can occur in high-power accelerators. Therefore, the accelerator’s inner surfaces have to be conditioned before its use at high gradient levels in Radiation Therapy machines. At Siemens, we have developed a technique to automatically condition accelerator structures by continually inspecting the a...

This paper presents a closed-loop control of an 800W fuel cell power system consisting of phosphoric acid fuel cell (PAFC), an ultracapacitor, power controlling unit and grid side filters. Simulation results represent the dynamics of the PAFC and its related power conditioning devices including grid connection. The proposed model is based on mathematical equations. The modeling and simulation i...

How Purkinje cell (PC) activity may be altered by learning is central to theories of the cerebellum. Pavlovian eyelid conditioning, because of how directly it engages the cerebellum, has helped reveal many aspects of cerebellar learning and the underlying mechanisms. Theories of cerebellar learning assert that climbing fiber inputs control plasticity at synapses onto PCs, and thus PCs control t...
