The paper is devoted to developing an approach to solving the problem of structure identification of layered minerals of the kaolinite group by the Rietveld method. The calculations of the intensity of the diffracted X-ray radiation are performed for the koalinit samples obtained from different fields. Qualitative agreement between calculated and experimental results has managed the solution of the identification problem for the kaolinite unit cell Glukhovtsy deposit. The obtained results indicate the possibility of identifying the features of the crystal structure of layered minerals by direct calculation of diffraction patterns.

In article questions of modeling of priority management by formation of information streams in information systems with the centralized source of data with use of the mechanism of sockets are considered. This question is staticized in connection with necessity of optimum control of information processes in the automated control systems. Management is based on change of priorities of forming processes, depending on ranks of clients. On the basis of an experimental material the analytical dependences establishing the relations of parameters and criteria of management are received.

Construction lending risks define a special operations procedure for lender. The most important measure to construction lending risk minimization are the covenants (information and financial). The information covenants are used for minimization the hidden information (pre-contractual opportunism), and financial covenants (positive and negative) – for minimization the hidden action (post-contractual opportunism). Institutionalization of covenants as a relevant control and supervision procedure allow to reduce information asymmetry and make the construction lending process less risky and more predictable for concerned parties (agent and principal).
