This paper presents a new control method for simultaneous compensation of instantaneous reactive power and current harmonics by parallel active filters (PAFs). Reference compensating currents of PAF are calculated using the subtraction of instantaneous power from its average value. In this way, it is possible omitting high/low pass filter(s) from the control circuit of PAF, which usually result...

The asymmetric unit of the title heterometallic coordination polymer, {[Cu(3)Yb(2)(C(7)H(3)NO(4))(6)(H(2)O)(12)]·2H(2)O}(n), contains one Yb(III) and two Cu(II) atoms. The Cu(II) atom that is located on an inversion center is N,O-chelated by two pyridine-2,5-dicarboxyl-ate (pdc) anions in a square-planar geometry; the Cu atom located on a general position is N,O-chelated by two pdc anions in th...

An UPQC (Unified Power Quality Conditioner) is anequipment composed by two active conditioners operating in a combined way. One of the active conditioners is connected in series with the electrical power system, allowing the compensation of problems in the system voltages. The other active conditioner is connected in parallel with the electrical system, and allows the compensation of current ha...

In this paper, a new contact force control technique, based on the modified Takagi-Sugeno model and parallel distributed compensation concept is developed to suppress vibrations between pantograph catenary by regulating reference value, thereby achieving stable current collection. The proposed method uses simple standard PID fuzzy controllers. two controllers guarantee designed system's robust ...

The theory of distributed detection is receiving a lot of attention. A common assumption used in previous studies is the conditional independence of the observations. In this paper, the optimization of local decision rules for distributed detection networks with correlated observations is considered. We focus on presenting the detection theory for parallel distributed detection networks with fi...

Performance profiling generates measurement overhead during parallel program execution. Measurement overhead, in turn, introduces intrusion in a program’s runtime performance behavior. Intrusion can be mitigated by controlling instrumentation degree, allowing a tradeoff of accuracy for detail. Alternatively, the accuracy in profile results can be improved by reducing the intrusion error due to ...

In this paper, recently proposed Temporally Varying Weight Regression (TVWR) is investigated in two ways for noise robust speech recognition. Firstly, since typical model compensation approaches assume that the noise feature is independent and identically distributed, non-stationary noise environment can be poorly compensated using conventional model compensation approaches in the standard Hidd...
