Dislocation nucleation plays a key role in plastic deformation of diamond crystal. In this paper, homogeneous and heterogeneous nucleation nature for diamond 16112 glide set dislocation and 12110 shuffle set dislocation is studied by combining molecular dynamics method and continuum mechanics models. Our results show that although heterogeneous dislocation nucleation can decrease its activation energy,...
This paper studies how to consolidate Virtual Machines (VMs) on physical severs in order to minimize the energy consumption in Cloud data centers. In Cloud data centers, a major energy consumption component is the physical servers, and it is a way to save the energy by consolidating VMs onto fewer VMs and shut down the idle physical servers. However, executing more VMs on fewer physical servers should...
In terrestrial-satellite hybrid networks, traditional TCP performance degrades a lot due to long propagation delays and high bit error rates link. Performance enhancing proxy(PEP) can shorten round trip time loop time and Peach can enhance the performance over high bit error rates link. In this paper, we propose a new scheme that combines PEP and TCP Peach for terrestrial-satellite hybrid networks...
