Mathematical Models for Evaluation of the Higher Education System Functions with DEA Approach

Authors: Firsova А. A., Chernyshova G. Y.

The purpose of this research is to develop the Data Envelopment Analysis (DEA) methodology for modeling of the assessment of the regional higher education systems effectiveness. The importance and topicality of this study is based on the increasing role of universities in the economic development of regions and countries in recent decades as well as the need to develop approaches for assessing the university effectiveness, and using mathematical models and methods for these goals.

Classification and Recognition of Structures of Genetic Sequences

Authors: Tverdokhlebov V. A., Kariakin D. A.

For solving problems of determining the relationships between the properties of organisms and the properties of the corresponding genetic sequences, we proposed a classification of genetic sequences based on numerical indicators of recurrent and Z-recurrent shapes, which define the structure of functional relationships of elements in sequences. For numerical indicators of recurrent and Z-recurrent shapes, we introduce a method of classification of genetic sequences.

A Method of Protected Distribution of Data Among Unreliable and Untrusted Nodes

Authors: Kosolapov Y. V., Pevnev F. S.

We consider a model of protecting the confidentiality and recoverability of data in a distributed storage system. It is assumed that in- formational blocks are coded into the code blocks. Then the blocks are divided into parts and distributed among repositories of the distributed storage. A modification of the code noising method is con- structed which simultaneously provides computational resistance to coalition attacks on confidentiality of stored data. Moreover, the modification also provides protection from the failure of a part of the storage nodes.
