the microgrid concept provides attractive solutions for reliability enhancement of power distribution systems. normally, microgrids contain renewable-energy-based distributed generation (dg) units, which their output power varies with different environmental conditions. in addition, load demand usually changes with factors such as hourly and seasonal customer activities. hence, these issues hav...

hereditary ataxias are heterogeneous group of neurodegenerative disorders classified mainly into more than 40 autosomal dominant cerebellar ataxias and 50 recessive ataxias. large amount of nearly uncommon subtypes with extensive phenotypic overlap and relatively high rate of abnormal repetitive sequence expansions, such as trinucleotide repeat expansions make diagnostic genetic testing complic...

presence of distributed generation (dg) in electric distribution systems provides an attractive new alternative in capacity expansion planning of these systems. in this paper a new model is developed for solving simultaneous placement of hv/mv substations and dg units as a static planning tool. this model aims to minimize fixed and variable costs of planning. constraints related to dgs, substat...
