Numerical algorithms based on uniformization have been proven to be numerically stable and computationally at tractive to compute transient state distributions in ho mogeneous continuous time Markov chains Recently Van Dijk van Dijk formulated uniformization for non homogeneous Markov processes and it is of interest to investigate numerical algorithms based on uniformiza tion for non homogeneou...

TCSC has been proposed to enhance the voltage stability by changing the reactive power distribution in the power system. Authors have discussed the effect of TCSC on steady state voltage stability and small-signal voltage stability. This paper discusses the TCSC’s enhancement on transient voltage stability. A TCSC model that is suitable for transient voltage stability analysis is proposed. This...

This paper presents a phase-locking-loop-based (PLL-based) charge control scheme to enhance the cross regulation (CR) performance of charge-controlled SIMO Buck DC-DC without freewheel period. By combining PLL structure with traditional scheme, each channel could be regulated by an independent loop. Moreover, gain-adapted pump (GACP) technique is applied for stability in multi-load condition. T...

The use of a super-capacitor as storage device integrated with Voltage source converter-based shunt-connected Static Synchronous Compensator (STATCOM) is proposed for improving the STATCOM performance during sudden large disturbances in power network. was applied across capacitor disturbance condition. MATLAB simulations were carried out verification secondary function like oscillation damping,...

The impact of large-scale grid-connected PV (photovoltaics) on power system transient stability is discussed in this paper. In response to an increase of PV capacity, the capacity of conventional synchronous generator needs to be reduced relatively. This leads to the lower system inertia and the higher generator reactance, and hence, the power system transient stability may negatively be affect...

UPFC is a versatile FACTS controller that can regulate the Power Flow through the Line by controlling its Series and shunt parameters. In shunt it is having STATCOM and in series SSSC are employed can independently control the Line Power Flow. Two Converters improves the flexibility and provide additional degree of freedom in Power System. With the application of UPFC, Transient stability of th...

In color TV broadcasting standards, such as NTSC and PAL, the limited bandwidth of the chrominance signals produces relatively slow chrominance transitions, causing smeared color edges in the received images. In this paper, we present an adaptive color transient improvement algorithm for enhancing color edge transition of images. By using a local image feature dependent gain control function to...

to the editor: There is currently no effective pharmacologic treatment for chronic aphasia, a frequent and incapacitating consequence of hemispheric stroke. We report the case of a 52-year-old right-handed woman, who had a stroke that affected her left insula, putamen, and superior temporal gyrus. Three years later, her speech was still restricted to stereotyped syllables, with not a single ide...

SRAM is the most crucial part of memory designs and are imperative in many simple or compound applications that implicate system on chip (SoCs). Power dissipation and stability has now become the most essential area of concern in sub-micron SRAM cell design with continuous technology scaling according to Moore’s law. At latest, retrenchment of channel length MOSFET is directly proportional to t...
