Design of power system stabilizers using evolutionary algorithms
… oscillations has been of major concern to power system engineers. These oscillations range from 0.1 to 3Hz and tend to be poorly damped especially in systems equipped with high gain fast acting AVRs and highly interconnected networks. If these oscillations are not adequately damped, they may …

An HPLC method for simultaneous determination of residual benomyl and MBC on apple foliage without cleanup
… of this mixture injected onto the HPLC system. Separation is accomplished by the use of a Brownlee LiChrosorb silica gel column with a guard column and' operated with a mixed mobile phase consisting of chloroform and hexane (4:1) saturated with water. MBC, a degradation product of …

A New Special Protection Scheme for Power System Controlled Separation
A new power system controlled separation scheme is proposed to prevent the propagation of cascading failures across a transmission network should it undergoes a major disturbance, thereby reducing the possibility of a large-scale blackout. This scheme is developed based on a set of conjectures, …

The role of binary stars in searches for extrasolar planets by microlensing and astrometry
… caustic crossings, in the case of a binary lens system. In principle, the fraction of binary stars at a certain separation range can be estimated based on the number of measured microlensing events. However, a binary system may produce a light curve which can be fitted well as a single lens light …

Analysis of a Major Electric Grid – Stability and Adaptive Protection
Protective systems of the electric grid are designed to detect and mitigate the effects of faults and other disturbances that may occur. Distance relays are used extensively for the detection of faults on transmission lines. Out-of-step relays are used for generator protection to detect loss of …

Monoclonal antibody (mAb) purification by counter current chromatography (CCC)
… mammalian cell culture, using aqueous two-phase systems (ATPS) of inorganic salts and polymer. A polyethylene glycol (PEG) and sodium citrate system was found to be the most appropriate by robotic phase system selection. The search for an economical alternative to protein A HPLC is a substantial …
