the aim of this research is to calculate the elastic constants and bulk modulus of cu-20 wt% ni random nanoalloy. the molecular dynamics simulation technique was used to calculate the mechanical properties in npt ensemble. the interaction between atoms as well as cohesive energy in the nanoalloy modeled systems was calculated by morse et al. two body potential. also the temperature of the syste...

Virtual services on computation resources like CPUs and storages are supported to applications by using virtual machines in server clusters. Virtual machines with application processes can migrate from host servers to guest servers. In this paper, we discuss a process migration approach to reducing total electric energy consumption of servers by taking advantage of virtual machines in a cluster...

Micro energy grids have many merits and promising applications under the smart grid vision. There are demanding procedures for their optimal planning and performance enhancement. One of the key features of a micro energy grid is its ability to separate and isolate itself from the main electrical network to continue feeding its own islanded portion. In this paper, an optimal sizing and operation...

The Ryu-Takayanagi formula relates the entanglement entropy in a conformal field theory to the area of a minimal surface in its holographic dual. We show that this relation can be inverted for any state in the conformal field theory to compute the bulk stress-energy tensor near the boundary of the bulk spacetime, reconstructing the local data in the bulk from the entanglement on the boundary. W...

Non-linear absorption of femtosecond laser pulses enables the induction of structural changes in the interior of bulk transparent materials without affecting their surface. This property can be exploited for the transmission welding of transparent dielectrics, three dimensional optical data storages and waveguides. In the present study, femtosecond laser pulses were tightly focused within the i...

With the assumption that photovoltaic power plants will use all available roof areas in the future, it is not possible to integrate the entire PV potential in today's low-voltage distribution grids. Due to the enormous feed-in of fluctuating electrical power in low-voltage grids by smallscale photovoltaic plants, transformers and cables can reach their loading limits. Moreover, the grid voltage...
