RATIONALE In cardiac muscle, Ca(2+)-induced Ca(2+) release (CICR) from the sarcoplasmic reticulum (SR) is mediated by ryanodine receptor (RyR) Ca(2+) release channels. The inherent positive feedback of CICR is normally well-controlled. Understanding this control mechanism is a priority because its malfunction has life-threatening consequences. OBJECTIVE We show that CICR local control is gove...

When a three-phase induction generator (IG) supplies unbalanced loads, its terminal voltages and line currents are also unbalanced, which may cause the IG to overheat and need to be derated. A single-phase loaded self-excited induction generator (SEIG) works under most unfavorable load unbalance conditions. This paper proposes a three-capacitor circuit scheme and a method to find the values of ...

The topology and control are discussed of a distribution static compensator (DSTATCOM) that can be operated flexibly in the voltage or current control mode. In the voltage control mode, the DSTATCOM can force the voltage of a distribution bus to be balanced sinusoids. In the current control mode, it can cancel distortion caused by the load, such that current drawn by the compensated load is pur...

Multi-port converter with three active full bridges, two series-resonant tanks and a Multi-winding transformer is proposed. It uses a single power conversion stage with high-frequency link to control power flow between batteries, load and a renewable source such as fuel cell. The converter has capabilities of bidirectional power flow in the battery and the load port. Use of series-resonance aid...

This paper proposes a control method for an electrolytic capacitor-less dual inverter compressors. Single-phase motor drive systems are required to minimize vibrations, maintain high power factor, and meet the limit harmonic current emissions. The proposed achieves reduction of dq-axis currents, low grid THD under periodic load torque fluctuations. effectiveness is demonstrated via experimental...

The objective of this study was to adequately examine potential wave fields, flow and suspended load changes in different wind turbine foundations. Accordingly, applied the hydrodynamic model simulate waves, currents, area. simulation results are based on assumption that dredging rubble bed trimming were performed for 8 h per foundation setting operation completed 2 h. influence tripile jacket ...
