Anode grounding modules provide electrochemical protection against corrosion of metal constructions. The functional modeling technique includes sequent decomposition of manufacturing and quality control processes. The functional-technological model describes activities, technological equipment, raw materials, and quality requirements. The complex functional model in IDEF0 notation is presented.

Integration of information resources on the properties of semiconductor materials developed in different countries is necessary for creation of new materials with the required properties. Federated approach to autonomous data sources integration is suggested. The approach allows the integration of data storage and access of physically distributed data. The data flow model and functional models of autonomous data sources integration are developed. Continue... |

The problem of creating and implementing testing technology students in higher education that meets the requirements of saving time-consuming teacher is considered. There are various approaches to practical organization of the preparation, execution and processing of survey results used in different conditions. A modification of the method previously proposed by the authors that improves performance and is based on cloud computing technology is suggested. The results of the practical application of technology are given.

The paper is devoted to analysis of algorithm to create functional approximation for the target Lipschitz-bounded surjective function via a composition of functions from a given set. The direct search algorithm is introduced at first, then the possibilities of optimization are discussed. After that an optimized algorithm is built. Obtained algorithms are compared on the problem of approximating Mesh network node degree distribution.

The paper presents the analysis of features of programming graphical applications for processing and visualization of large amounts of data with high-performance hybrid computing cluster systems. Considered hybrid architecture of computing cluster, allow to implement of parallelism using CUDA and MPI at three levels: the cluster nodes, multicore and GPU video cards. The approach is proposed to organization of hybrid parallelism estimated its effectiveness by implementing of software complex of visualization synoptic data using hybrid cluster.
