This paper proposes a novel approach for generation scheduling using sensitivitycharacteristic of a Security Analyzer Neural Network (SANN) for improving static securityof power system. In this paper, the potential overloading at the post contingency steadystateassociated with each line outage is proposed as a security index which is used forevaluation and enhancement of system static security....

We complete the classification of binary patterns in partial words that was started in earlier publications by proving that the partial word avoidability index of the binary pattern ABABA is two and the one of the binary pattern ABBA is three.

Factorial designs are arguably the most widely used designs in scientific investigations. Generalized minimum aberration (GMA) and uniformity are two important criteria for evaluating both regular and non-regular designs. The generation of GMA designs is a non-trivial problem due to the sequential optimization nature of the criterion. Based on an analytical expression between the generalized wo...

We analyze pattern formation in doubly resonant second-harmonic generation in the presence of a competing parametric process, also named the internally pumped optical parametric oscillator. Different scenarios are established where either the upor down-conversion processes dominate the spatiotemporal behavior. The possibility of obtaining exact solutions above threshold for the parametric oscil...

ORGANOHALOGEN COMPOUNDS – Volume 66 (2004) 278 Introduction Most of the PCB pollutions are caused by industrial application. PCB-containing mixtures whose compositions are well known and constant should be rapidly and precisely analyzable as total PCB to monitor real pollution exposure. Consequently, a simple but reproducible and cheap method for operative control is needed which should be peri...

Three mechanisms-cellular automata, finite automata , and L-systemsfor generat ing static patterns are compared. Matrix subst itution systems, nondeterministic extensions of iterative matrix homomorphisms, are also introduced and shown to be equivalent to finite automata. Two different ways for taking the limit of a sequence of finite resolution patterns produced by any of the mechanisms are st...

one of the most important issues that faced cities in developing countries with a crisis is expanding informal settlement in them. these settlements with differences in definition are known as occupational, changing, marginal, self-made and uncontrolled housing. it is estimated that about 1 billion man in all over the world live in such kinds of places. these zones are the texture for creation ...
