in this paper, a combinational optimization algorithm is introduced to obtain the best size and location of static compensator (statcom) in power systems. its main contribution is considering contingency analysis where lines outages may lead to infeasible solutions especially at peak loads and it commonly can be vanished by load-shedding. the objective of the proposed algorithm is firstly to pr...

This paper develops a computational technique for finding the maximum allowable load of mobile manipulators for a given trajectory. The maximum allowable loads which can be achieved by a mobile manipulator during a given trajectory are limited by the number of factors; probably the dynamic properties of mobile base and mounted manipulator, their actuator limitations and additional constraints a...

background and aims: this is a pilot study investigated the prevalence of hearing impairment and the impact of the known risk factors for hearing loss on infants at risk born in kuwait. methods: two hundred infants with risk of hearing impairment who met the joint committee on infants hearing (1990) criteria were screened. all newborns were included in this study if they had hospital stay for m...

I Buckling and postbuckling behavior under axial compression is analyzed for a long circular cylinder containing an axisymmetric imperfection. Bifurcation I stresses are investigated for all possible modes, both periodic and aperiodic, and postbuckling analysis reveals that bifurcation is not always associated with a loss of load-carrying capacity. The results provide some theoretical foundatio...

BACKGROUND Polyomavirus associated nephropathy (PVAN) is a significant cause of early allograft loss and the course is difficult to predict. The aim of this study is to identify factors influencing outcome for PVAN. METHODS Between 2006 and 2014, we diagnosed PVAN in 48 (7.8%) of 615 patients monitored for BK virus every 1-4 weeks after modification of maintenance immunosuppression. Logistic ...

In restructured electricity markets, an effective transmission pricing method is required to address transmission issues and to generate correct economic signals. Transmission line constraints can result in variations in energy prices throughout the network. These prices depend on generator bids, load levels and transmission network limitations. A congestion charge is incurred when the system i...
