We investigate the local existence, finite time blow-up and global existence of sign-changing solutions to inhomogeneous parabolic system with space-time forcing terms $$ u_t-\Delta u =|v|^{p}+t^\sigma w_1(x),\,\, v_t-\Delta v =|u|^{q}+t^\gamma w_2(x),\,\, (u(0,x),v(0,x))=(u_0(x),v_0(x)), where $t>0$, $x\in \mathbb{R}^N$, $N\geq 1$, $p,q>1$, $\sigma,\gamma>-1$, $\sigma,\gamma\neq0$, $w_1,w_2\no...

This paper gives a new insight into the concept of load compensation using shunt active filter (SAF) under ideal and non-ideal source voltage conditions. A novel approach based on an improved instantaneous active and reactive current component method is proposed. The performance of the proposed control strategy has been compared with instantaneous reactive power theory, symmetrical component th...

Harmonics distortion is a crucial problem in microgrid. Harmonic sources can be categorized as two main factors: renewable energy integration and nonlinear loads. Both factors are investigated in this paper. For renewbale energy, photovoltaic (PV) power is one of the most effective solutions for energy crisis and it is showing great potential for serving customers in microgrid. A threephase PV ...

This paper gives a literature review of detection theory and information theory in the Poisson regime, where the channel model is a Poisson point process whose instantaneous rate is controlled by the input. I. Communication under the Poisson Regime In the semi-classical model of photodetection, the output of the photodetector (e.g. a p-i-n diode) is the superposition of two independent Poisson ...

Rhodium(III) complexes containing 2-(2'-pyridyl)quinoline (PQ) were prepared by the reaction of RhCl3 6H2O and PQ in 1:2 mole ratio followed by addition of an excess of sodium salts to the reaction mixture. The new complexes cisRhX2(PQ)2 Y (where X = NO2 , Y = PF6 ; X = SCN or NO3 , Y = Cl; X = Y = I) and cisRh(N3)2(H2O)2(PQ) PF6 were characterized by elemental analysis, conductivity measuremen...

This paper describes an efficient yet accurate methodology for estimating system damping. The proposed technique is based on linear dynamic system theory and the Hilbert damping analysis. The proposed technique requires capacitor switching waveforms only. The detected envelope of the intrinsic transient portion of the voltage waveform after capacitor bank energizing and its decay rate along wit...

Electrical power quality (PQ) disturbance has become an important issue in India. On a distribution network, it is mainly caused by various nonlinear loads. Due to the varying power produced, it is affected by penetration of solar PV system as well. Therefore it is necessary detect and classify PQ events in account of evaluating a PQ problem. In other side due to increase of smart meters in sma...
