Virtual machine (VM) scheduling in a dynamic cloud environment is often bound with multiple quality of service parameters; therefore, it classed as an NP-hard optimization problem. Swarm-based metaheuristics, such the whale algorithm (WOA), have gained notable reputation for solving problems. The unique bubble-net hunting behaviour and fast convergence led to development hybrid multi-objective ...

Fog computing has been prioritized over cloud in terms of latency-sensitive Internet Things (IoT) based services. We consider a limited resource-based fog system where real-time tasks with heterogeneous resource configurations are required to allocate within the execution deadline. Two modules designed handle continuous streaming tasks. The first module is task classification and buffering (TCB...

Despite the fact that many governments try to set rules guarantee having resistant buildings, there are vulnerable structures in world. Hence, establishing earthquake relief centers is an important issue order control effect of earthquake. Iran a country middle east which severely against Yazd central city Iran. Since no such study for city, this considered study.  The parcels' layer GIS map ha...

Abstract The most crucial function in drilling wells is the rate of penetration, which modeled by many researchers, and best one Young-Bourgyen model, used this study. Eight factors affecting penetration have been studied approved developing a mathematical equation that shows combined effects these variables on optimization. This paper presents an efficient way to find optimum values for parame...
