Annotation: In this article was used model of non-linear pendulum for finding optimal shape of a curved strip. The shapes with bend point presents via elliptic functions. Result of the article allows to improve construction of an aerial of satellite.

Annotation: The structure of «posts» for storage in social networks with a small amount of users is offered. The developers face the problem of choosing an effective system of information storage. The data structures created in the work consider features of no-SQL and SQL storages of data. Productivity of each models is checked on inquiries of different complexity to databases of different structure. The efficiency of the offered structures is checked on concrete data

Annotation: Developed computer algorithms that simulate the dynamic interaction of elastic blocks through thin viscoelastic layer in structurally inhomogeneous media such as rocks. On the basis of rheological models are constructed for the deformation of the material layers of different levels of complexity. In the numerical solution of one-dimensional problems of applied monotonous grid- characteristic schemes with a balanced number of time steps in the blocks and interlayers . The problems of software implementation of algorithms on multiprocessor systems with graphics cards . Numerical results demonstrate the qualitative features of the propagation of plane waves in materials with a layered microstructure.

Annotation: The methods of updating the database of physical effects are presented in the article. The generalized procedures of the methods and the recommendation about their performance are described. The application methods are dwelled on.

Annotation: Work is devoted a problem of construction optimum immune net model for complex investment projects for the purpose of the risks forecasting and possibility of timely updating in the course of its realizations. The perspective approach of artificial immune systems (AIS), based on concept formal peptide and procedure of a molecular recognize is used. Advantages of ap-plication AIS at the intellectual analysis of the data is possibility of parallel processing of a considerable quantity of the experts opinions, forecasting of risks and timely control of the course of the complex projects performance. At realizations immune net technologies the pro-cedure of optimum model construction on the basis of selection of the most informative attributes has great value. For the decision of this problem it is used the method of principal components.
