We study design alternatives for, and describe prototypes and performance of, a scalable and highly available Web server accelerator. The accelerator runs under an embedded operating system and improves Web server performance by caching data. The basic design alternatives include a content router or a TCP router (without content routing) in front of a set of Web cache accelerator nodes, with th...

Solid electrolytes for all solid sodium-ion batteries have been attracting much attention as an alternative energy storage system, which the advantage of being extremely safe because it can be charged quickly and is nonflammable. We synthesized anti-perovskite type Na3OX (X = Br, I) with high purity, by reactions halogen mixtures sodium oxides. After mixing, was filled in alumina crucible heate...

By pervasiveness of cloud computing, a colossal amount of applications from gigantic organizations increasingly tend to rely on cloud services. These demands caused a great number of applications in form of couple of virtual machines (VMs) requests to be executed on data centers’ servers. Some of applications are as big as not possible to be processed upon a single VM. Also, there exists severa...

The behavioral phenomena of sensory attention are thought to reflect the allocation of a limited processing resource, but there is little consensus on the nature of the resource or why it should be limited. Here we argue that a fundamental bottleneck emerges naturally within Bayesian models of perception, and use this observation to frame a new computational account of the need for, and action ...

In distributed systems shared by multiple tenants, effective resource management is an important pre-requisite to providing quality of service guarantees. Many systems deployed today lack performance isolation and experience contention, slowdown, and even outages caused by aggressive workloads or by improperly throttled maintenance tasks such as data replication. In this work we present Retro, ...

Relativistic configuration interaction calculations have been performed for the 1s→np (n=4-8) photoabsorption transitions in Br I and Br II and transition energies and transition probabilities have been evaluated. These data are necessary to interpret the experiment photoabsorption spectra. The K edge energy of Br I and Br II have also been computed and compared to the existing values when avai...

We study a stochastic network that consists of two servers shared by two classes of jobs. Class 1 jobs require a concurrent occupancy of both servers while class 2 jobs use one server only. The traffic intensity is such that both servers are bottlenecks, meaning the service capacity is equal to the offered workload. The real-time allocation of the service capacity among the job classes takes th...

We propose a framework which ports Dirichlet Gaussian mixture model (DPGMM) based labels to deep neural network (DNN). The DNN is used to extract a low-dimensional unsupervised speech representation, named as unsupervised bottleneck feature (uBNF), which captures considerable information for sound cluster discrimination. We investigate the performance of uBNF in query-by-example spoken term det...
