In this work we show that simple classic models of power grids, albeit frequently utilized in many applications, may not be reliable for investigating cascading failures problems. For purpose, develop a novel model, based on structure-preserving approach, to obtain network-based description grid, where nodes correspond generators and buses, while the links physical lines connecting them. additi...

based on two integration steps, an optimization framework is proposed in this work for the synthesis and design of complex distillation sequence. the first step is to employ heat integration in sequence and reduce the heat consumption and total annual cost of the process. the second one is to increase the exergetic efficiency of sequence by generating power in implemented expanders in sequence....

background and aims: tomato yellow leaf curl virus (tylcv) is one of the most destructive viruses of tomato that leads to reduced tomato yield up to 100% in tropical and subtropical regions. in this study, the complete sequence of tylcv isolate from hormozgan province, iran and its recombination evsent was determined. methods: tylcv infected tomato was collected from hormozgan province. total d...

Composites have proved their usefulness in the automotive industry during recent years. Many automobile companies use them different parts to reduce weight without hampering strength. In a composite material, Lay-up sequence and orientation highly affects properties of laminate. Therefore, it is important perform design optimization on component achieve high strength minimum weight. This paper ...

To identify the correspondence between different dynamic responses of Daguangbao landslide and faulting mechanisms composite-hypocenter, whole hypocenter Wenchuan earthquake was divided into four sub-hypocenters. On another hand, based on location Dauangbao landslide, composite-hypocenter Initial Sub-hypocenter, Approaching Local Receding sub-hypocenter Terminal sub-hypocenter. Subsequently, re...

despite the development of appropriate academic and experiential background knowledge management and its manifestation as a competitive advantage, many organizations have failed in its effective utilization. among the reasons for this failure are some deficiencies in terms of methodology in inappropriate recognition and translation of km dimensions and lack of systematic approach in establishme...
