Cloud computing is widely adopted by corporate as well as retail customers to reduce the upfront cost of establishing computing infrastructure. However, switching to the cloud based services poses a multitude of questions, both for customers and for data center owners. In this work, we propose an algorithm for optimal placement of multiple virtual data centers on a physical data center. Our alg...

This paper addresses the change from batch mode to online mode in offices and workplaces in the 1970s and 1980s. Particular focus is on the role of IBM and the 3270 display terminal. The change had profound implications for users and system developers. The paper is based on oral history interviews with former employees of the two large Danish service bureaus, Datacentralen and Kommunedata, and ...

in current work, cds/black carbon nanocomposites were successfully synthesized with the aid of chestnut and cadmium nitrate as the starting reagents. besides, the effects of preparation parameters such as reaction time, and precursor concentration on the morphology of products and removal of heavy metals (hg+2, pb+2) were studied by scanning electron microscopy images and batch adsorption mode....

Kalman filters and ARIMA models provide optimum control and evaluation techniques (in a minimum squared error sense) for clocks and precision oscillators. Typically, before the models can be used, an analyeie of data provides estimates of the model parameters (e.g., the phi's and theta's for an ARIMA model). These model parameters are often evaluated in a batch mode on a computer after a large ...

With current and upcoming imaging spectrometers, automated band analysis techniques are needed to enable efficient identification of most informative bands to facilitate optimized processing of spectral data into estimates of biophysical variables. This paper introduces an automated spectral band analysis tool (BAT) based on Gaussian processes regression (GPR) for the spectral analysis of veget...

BACKGROUND Overflow metabolism is an undesirable characteristic of aerobic cultures of Saccharomyces cerevisiae during biomass-directed processes. It results from elevated sugar consumption rates that cause a high substrate conversion to ethanol and other bi-products, severely affecting cell physiology, bioprocess performance, and biomass yields. Fed-batch culture, where sucrose consumption rat...

The paper reviews thoroughly a variety of issues related to mode estimation. The potential of self-organizing maps as an approach to mode detection is inquired here. The batch version of the standard SOM and a convex adjustment of it are compared with two kernel-based learning rules, namely, the generative topographic mapping and the kernelbased maximum entropy learning rule. A strategy for mod...

A public database of astrophysical (radio and other) catalogs (CATS), has been created at the Special Astrophysical Observatory (SAO). It allows a user to execute a number of operations in batch or interactive mode, e.g., to obtain a list and parameters of catalogs, to extract objects from one or several catalogs by various selection criteria, to perform cross-identification of different catalo...
