Static synchronous series compensator and static var compensator interaction on voltage stability limit enhancement and active power loss minimization through differential evolution algorithm
This paper proposes an application of differential evolution (DE) algorithm based extended voltage stability margin and minimization of real power loss incorporating static synchronous series compensator (SSSC) and static var compensator (SVC) devices. A new circuit element based model of SSSC and variable susceptance model of SVC are utilized to control the line power flows...

Validation of dynamic modelling of an industrial vibratory bowl feeder
This paper presents a simple approach to model an industrial vibratory bowl feeder. The vibratory feeder is a device used to separate, feed and locate automatically a variety of parts in order to speed up the process of manufacture and assemble in industry. The analytical model obtained is validated through an experimental setup, assembled in laboratory, composed by a...

Effect of drought stress on yield and yield components of maize hybrids
The effect of drought stress on yield and its components was studied on six (6) Iranian commercial corn hybrids at the Khorasan Razavi Agricultural Research and Natural Resources Institute Mashhad, Iran in 2010. The study was conducted in a randomized complete block design with three replications under drought stress conditions. There were significant differences among hybrids...
