Ontologies are increasingly gaining practical usage for semantic data in various ways and across multiple domains. From this growing applicability arises an evergreater need to manage large datasets, reduce analytical complexity and efficiently as well as accurately integrate different heterogeneous ontologies into or within existing systems, all while minimizing data corruption and maintaining...

We consider a class of general Gt/Gt/1 single-server queues, including the Mt/Mt/1 queue, with unlimited waiting space, service in order of arrival, and a time-varying arrival rate, where the service rate at each time is subject to control. We study the rate-matching control, where the service rate is made proportional to the arrival rate. We show that the model with the rate-matching control c...

The RATAN-600 radio telescope allows us to carry out simultaneous multi-frequency observations using wide-band radiometers. Thus, we can account for the influence of the atmosphere using high frequency observations and the Galactic background using low frequencies, or observe instantaneous spectra of radio sources. Using these features a flexible astronomical data processing system (FADPS), ope...

The effect of moderately high doses of x-irradiation upon the reticulo-endothelial system of mice and rats was investigated. A dosage of 600 r to mice and 850 r to rats did not interfere with the ability of the RES to clear colloidal particles from the blood. However the 850 r x-ray dose to rats prevented recovery of normal phagocytic function after "blockade." In mice, 600 r interfered with th...
