Reliability of power system can be influenced by the maintenance strategy adopted for the system’s equipments. This study focuses on power circuit breakers maintenance planning based on the concept of reliability-centered ...

Abstract. If the centre of a group G is trivial, then so is the centre of its automorphism group. We study the structure of the centre of the automorphism group of a group G when the centre of G is a cyclic group.

soft drink wastewater statistically. Response surface methodology (RSM) based on face centred composite (CCF) design was implemented to investigate the influence of surfactant concentration and transmembrane pressure (TMP) as independent variables...

traps produce higher

current collapse in comparison to shallow centres. Not surprisingly the simulation results

show that increasing the trap density and trap cross-section decrease the output drain

current. Simulations of the effect...
