Object oriented systems are considered which can be decomposed into a finite number of objects. These systems are composed at runtime of interacting objects, residing in computer memory and holding the data to be processed. Every object is described in the realm of software by its class. So, at the architectural and language level, Object Oriented Systems are composed of classes, the basic object...
This paper introduces a technique for meter placement for the purpose of improving the quality of voltage and angle estimates across a network. The proposed technique is based on the sequential improvement of a bivariate probability index governing relative errors in voltage and angle at each bus. The meter placement problem is simplified by transforming it into a probability bound reduction problem,...
The main particularity of distribution system state estimation is the lack of real-time measurements. In order to establish the state estimation function, pseudo- measurements need to be introduced. As there is generalised uncertainty in the power demand, the load characteristics can be utilised to appropriately model the pseudo-measurements. This paper proposes two new approaches for modelling pseudo-measurements...
In this paper we have proposed design modifications in fiber optic loop buffer switch. This paper discusses an automatic gain controlling (AGC) scheme for the loop buffer. We have shown that by changing the position of EDFA automatic gain controlling scheme will not be required. We have utilized the availability of filter in tunable wavelength converter (TWC) to reduce number of components in the...
Several techniques for optical buffering have been given in past and still a lot of research is being done. Also, the rapid growth of the broadband communication has placed extreme demands upon the telecommunication infrastructure. This has generated an urgent requirement to introduce new technologies. Wavelength division multiplexing (WDM) is one of those techniques, which allows simultaneous propagation...
