Partricular features of overpassing local optima and providing near-optimal soultion in practical time has led researchers to apply metaheuristics in several engineering problems. Optimal design of diagrids as one of the most efficient structural systems in tall buildings has been concerned here. Jaya algorithm as a recent paramter-less optimization method is employed to solve the problem using...

background mainstay of post-burn reconstruction is release and split skin grafting. pedicle flaps are cumbersome to the patient, require multiple procedures and hospitalization. free flaps are technically demanding and facilities are not universally available. here we evaluated the local perforator flaps for post-burn reconstruction. methods we have used sixteen perforator propellar flaps for p...
