Virtualization technology plays a great role in cloud computing. Virtualization supports creation and migration of virtual machines (VM) on physical hosts. Live migration provides the load balancing of virtual machine. One of the objectives of live migration is that it should have minimum migration time as well as downtime so that application running on VM will be suspended for negligible time....

16. Abstract Four scale microconcrete model bridges were tested. Experimental variables included span, skew angle, stiffness, location and number of diaphragms. Service load level behavior was studied under static, cyclic and impact loads with successive removal of diaphragms. Behavior at overload and ultimate load conditions was documented from ultimate static and impact load tests. Characteri...

The design parameters of ribbed single-layer cylindrical reticulated shell structure rib and the internal force, structural deformation, bearing reaction natural vibration characteristics steel consumption are studied. Firstly, space analysis software MSTCAD2020 is used to calculate large-span structure, optimized by full stress method. Considering that number ribs 4, 5, 6, 7, 8, heights 1.2m, ...

mucosal surfaces of the body provide a universal entry portal for all known and emerging infectious pathogenic microbes. therefore, it seems that special vaccination strategies are needed for vaccines that can hinder the entry capability of pathogenic microbes through the mucosal surfaces. lactic acid bacteria are widely used in the food industry and are presently applied as delivery vehicles i...

background: the aim of present study was to evaluate the protective efficacy of live recombinant l. tarentolae expressing kmp11-ntgp96-gfp fusion as candidates for live engineered recombinant vaccine against visceral leishmaniasis in balb/c mice. methods: kmp-11 and nt-gp96 genes cloned into the pjet1.2/blunt cloning vector and then into pegfp-n1 expression vector. the kmp-11, nt-gp96 and gfp f...

Network Dispatcher (ND) is a software tool that \routes" TCP connections to multiple TCP servers that share their workload. It exports a set of virtual IP addresses that are concealed and shared by the servers. It implements a novel dynamic load-sharing algorithm for allocation of TCP connections among servers according to their real-time load and responsiveness. ND forwards packets to the serv...

CD8 T cells are a potent tool for eliminating intracellular pathogens and tumor cells. Thus, eliciting robust CD8 T-cell immunity is the basis for many vaccines under development. However, the relationship between antigen load and the magnitude of the CD8 T-cell response is not well-described in a human immune response. Here we address this issue by quantifying viral load and the CD8 T-cell res...

Tree depth and load balancing are two main metrics in overlay multicast network. Optimizing the two metrics with lightweight overhead is important for live media streaming. This paper proposes one scheme to construct optimized overlay multicast with short tree depth and load balancing via short random walk. The key idea is the preferential random walk based on fitness function in which the tree...

Many publish/subscribe systems implement a policy for clients to join to their physically closest broker to minimize transmission delays incurred on the clients’ messages. However, the amount of delay reduced by this policy is only the tip of the iceberg as messages incur queuing, matching, transmission, and scheduling delays from traveling across potentially long distances in the broker networ...

Web servers providing live coverage of events are hard to design due to a high degree of variation in the load, variation in geographical distribution of users and the frequency with which content is updated. In this paper, we propose domain caching, a technique that dynamically distributes the load on the server by instructing selected clients (domain caches) to cache server content and servic...
