Only little is publicly known about traffic in noneducational data centers. Recent studies made some knowledge available, which gives us the opportunity to create more realistic traffic models for data center research. We used this knowledge to create the first publicly available traffic generator that produces realistic traffic between hosts in data centers of arbitrary size. We characterize t...

As one kind of remote sensing images of land use composed by various categories of surface objects difficult to obtain multi-distribution model of class spectral feature, analyzing the spectral characteristics of LU of multispectral RS imagery, this paper presents a self-adaptive adjustment of clustering center method. Depending on the intercepted situation of the cluster centers between differ...

We consider the problem of testing whether a sample of observations comes from a single Poisson distribution. Of particular interest is the alternative that the observations come from Poisson distributions with different parameters. Such a situation would correspond to the frequently discussed situation of overdispersion. We propose a new test for this problem that is based on Anscombe’s varian...

the inappropriate space distribution of rural services causes many problems, including loss of adoptness, and unfair distribution of services according to the existing capacities. in this research, the studied region is “dehdez” zone of “izeh” province,”khuzestan” state. the goal of the present paper is to prpvide an optimal and ideal location finding of rural services centers in dehdez zone, i...

Quantum correlation between two particles and among three particles show nonclassic properties that can be used for providing secure transmission of information. In this paper, we propose two quantum key distribution schemes for quantum cryptographic network, which use the correlation properties of two and three particles. One is implemented by the Greenberger-Horne-Zeilinger state, and another...

Data centers have become ubiquitous in the last few years in an attempt to keep pace with the processing and storage needs of the Internet and cloud computing. The steady growth in the heat densities of IT servers leads to a rise in the energy needed to cool them, and constitutes approximately 40% of the power consumed by data centers. However, many data centers feature redundant air conditioni...

This paper presents a sequential approach for the assessment of a multi-layered distribution network from a cluster of collaborating suppliers to a large set of customers. The transportation network includes three segments: suppliers routes from suppliers to a consolidation and distribution center, full truckload routes toward regional distribution centers, and less-than-truckload distribution ...

Many similarities exist between research on combinatorial chemistry and natural products and research on dietary supplements and botanicals at the National Institutes of Health (NIH) Botanical Research Centers. The technologies used at the centers are similar to those used by other NIH-sponsored investigators. All centers rigorously examine the authenticity of botanical dietary supplements and ...

The stem epidermis in Torenia fournieri, which has budding potentialialities, is composed of one cell layer which can be easily separated from the rest of the stem segment at different stages of bud formation. As the buds are formed directly from the epidermis, without intermediate callus formation, it is possible to observe simultaneously the cell division centers over the entire excised epide...
