This paper is devoted to the general theory of linear systems of fractional order pseudo-differential equations. Single fractional order differential and pseudo-differential equations are studied by many authors and several monographs and handbooks have been published devoted to its theory and applications. However, the state of systems of fractional order ordinary and partial or pseudo-differential equations is still far from completeness, even in the linear case.

The identification of the right order of the equation in applied fractional modeling plays an important role. In this paper we consider an inverse problem for determining the order of time fractional derivative in a subdiffusion equation with an arbitrary second order elliptic differential operator. We prove that the additional information about the solution at a fixed time instant at a monitoring location, as "the observation data", identifies uniquely the order of the fractional derivative.

This paper considers the problem of building adaptive fuzzy-logic traffic control systems (AFLTCS) to deal with information fuzziness and uncertainty in case of heavy traffic streams. Methods of formal description of traffic control on the crossroads based on fuzzy sets and fuzzy logic are proposed. This paper also provides efficient algorithms for implementing AFLTCS and develops the appropriate simulation models to test the efficiency of suggested approach.

The authors presented a historical sketch abouth the department of military-medical supply and pharmacy of the military-medical academy since 1798. During the whole history of the department the academic staff has successfully combined educational and research work with solution of a practical questions of improvement of medical supply of the russian army and navy. During the different historical periods and on the basis of current requirements of military medicine and pharmacy it is necessary to develop theory and practice of medical supply and normative legal acts of the system of medical supply, to develop new examples of medical property, to develop manufacturing processes of medicinal products, quality management, to perform researches in the area of radiochemistry of medical products, forensic chemistry, toxicology, research of medical plants, medicinal water and etc.

Tajikistan is a country with numerous abandoned uranium mines and individuals residing in close proximity to these sites. Inspection of one of these sites next to the town of Taboshar revealed uncontrolled waste with elevated radiation levels. Convenience samples of subjects likely to have been exposed to uranium mining (i.
