Conventional dual active bridge (DAB) converters based on the non-resonant circuit topology have sever limitation of soft switching under light load conditions without complex multi-pulse modulations such as or triple phase shift. To address this technical problem, paper explores a symmetrical series-resonant bidirectional dc-dc converter (SSR-BDC). The SSR-BDC features variable frequency shift...

The gap junction modifier Rotigaptide (ZP123), which promotes cellular coupling, was hypothesized to decrease defibrillation thresholds during prolonged ventricular fibrillation (VF). Thirty-two New Zealand white rabbits were randomized to receive saline (control, n = 16) or Rotigaptide (n = 16). Following 4 min of untreated VF, biphasic defibrillation shocks were applied through chest wall pat...

variation of frequency and voltage by load changes in a microgrid is a challenge in droop control method. centralized restoration frequency or voltage in a microgrid requires communication link and therefore affects the advantage of decentralized droop control such as reliability, simplicity and inexpensiveness. this paper proposes a decentralized method that restores the frequency of a microgr...

Prolonged out-of-hospital ventricular fibrillation (VF) arrests are associated with reduced ECG dominant frequency (DF) and diminished defibrillation success. Partial reversal of ischemia increases ECG DF and improves defibrillation outcome. We have investigated the metabolic components of ischemia responsible for the decline in ECG DF and defibrillation success. Isolated Langendorff-perfused r...

In this paper, an attempt has been made to introduce a new control strategy including Plug-in Hybrid Electric Vehicle (PHEV) and Diesel engine generator to control the voltage and frequency of autonomous microgrids. The proposed control strategy has multiple advantages over the recent control methods in microgrids. The proposed method applies the primary and secondary frequency control strategy...

Rapid device aging in the nano era threatens system lifetime reliability, posing a major intrinsic threat to functionality. Traditional techniques overcome aging-induced slowdown, such as guardbanding are static and incur performance, power, area penalties. In manycore processor, system-level design abstraction offers dynamic opportunities through control of task-to-core mappings per-core opera...

The role of the cardiac sympathetic nerve activity in various cardiac diseases is typically evaluated using β-adrenergic receptor antagonists. However, these antagonists induce global denervation effects not only in the cardiovascular system, but also in the brain and kidney. The objective of this study was to detect the electrophysiological property changes due to 8 days of cardiac sympathetic...
