Agreeing on a method to identify interfaces is a desirable step in order to build a database of interfacial energy. So far, the expression Sigma X Interface has been used to identify interfaces. Unfortunately, this conventional method cannot express arbitrary interface geometries. In the present work, we review interface geometries and propose a systematic Orientation Method based purely on geo...

this paper proposes an optimal transmission expansion planning (tep) which is based on determining share of each line in merchandizing surplus (ms) of system, determining by independent system operator (iso). the more share of a line in ms of system denotes the priority of a line for expansion. the procedure of determining ms of each line in a power system is based on determining the ms share o...
