In this paper, we present a genetic algorithm (GA) for optimization of a multi-mode resource constrained time cost trade off (MRCTCT) problem. The proposed GA, each activity has several operational modes and each mode identifies a possible executive time and cost of the activity. Beyond earlier studies on time-cost trade-off problem, in MRCTCT problem, resource requirements of each execution mo...

background: hypoglycemia is one of the most common neonatal disorders, associated with severe complications. there has been a great deal of controversy regarding the definition and screening of hypoglycemia. therefore, in this study, we aimed to determine a cut-off value for blood glucose level in glucometer readings. methods: this cross-sectional study was conducted on 238 newborns at risk of ...

Flame stability inside a cylindrical micro-combustor was studied. Considering occurrence of heat recirculation, the respective relations were written and with parameters such as motion speed of reactants, flame propagation speed and thermal conductivity of the combustor’s wall, flame stability and its location inside micro-combustor were studied. It was found that for each thermal conductivity ...
