Annotation: The paper examines the testing technology of ready-to-use (commercial-off-the-shelf) software product and specifies the organization of its testing in comparison with the organization of testing a software product at the design and development stages. The original documentation necessary for testing and requirements for it are considered and analyzed. The main documents developed during the development and execution of tests are presented.

Annotation: The paper considers a method of constructing information aggregation systems on the way of the client-server architecture . Proposed a simulation model of the information aggregation system with the goal the most efficient system configuration . Experimental data are collected and a mathematical model of the system is constructed based on the obtaine d simulation model .

Annotation: One of the most important stages of software life cycle is testing and debugging. One of importa nt parameters of testing is its duration. To determine this parameter we can use the Jelinski-Moranda reliability model to calculate the time between failures (finding errors) and Halstead’s measures to predict the total number of failures on the planning phase of software development. The total number of failures is used by Jelinski-Moranda model.

Annotation: When processing different survey data, there are often technical difficulties in transferring them from questionnaire formats (for example, excel-tables) to program data directly involved in their mathematical processing. The case when it is necessary to integrate the means of the program for calculating data, implemented in C ++, and the program for downloading this data from excel-tables, implemented in C #, is considered. A sequence of actions for the program integration of object-oriented libraries is described. The fragments of the program code for the implementation of the specified sequence of actions are given.

Annotation: One of the ways of increasing oil production is to study the core materia l – piece of rock extracted at the site of the oil field. It’s convenient to make detail analysis of core material on it’s digital model derived by means of x-ray tomography. In the paper we consider the visualization of the cross section of the digital co re material model, which allows to study the internal structure and density distribution of the core material, the distribution of some mineral inclusions, to identify cracks and other features .

Annotation: This article represents usage of Internet of Things technologies in environmental monitoring . Using the case of Moscow Environmental Monitoring System, disadvantageous features of existing monitoring systems were observed, such as deployment speed, station size, maintenance costs. The authors propose a new approach to deve lopment of such systems using IoT technologies. This will make it possible to create easily scalable low-cost systems with high energy efficiency through the use of modern technologies of long-range and near-range wireless communication and connections ove r the Internet.

Annotation: The efficiency of clusters depends on the load balancing module, namely, on the load balancing algorithm used in it. The paper gives a review of the main balancing algorithms in terms of their impact on the speed of query processing computing cluster . The software solution for simulation modeling was used for the analysis. As a result of the simulation, were obtained the comparative values of the performance of the considered algorithms and revealed the factors that influencing the obtained values.

Annotation: The article describes the experience of the development and practical study of artificial intelligence systems in the educational process of bachelors on the example of creating an artificial neural network for recognition of handwritten digits. Students received knowledge about t he internal structure and processes occurring in artificial neural networks, developed skills for training neural network (recognition accuracy after learning the network was 96%), obtained skills in the process of development and testing of the neural net work.
