The article considers energy efficient algorithm for mobile devices with self-organizing wireless Wi-Fi net-work (Ad-hoc). It is designed for using in mobile devices based on the operating system (OS) Android. The proposed algo-rithm allows optimizing the interaction of described devices with wireless networks, both from the point of energy saving and automation capabilities of the process. It is achieved by improving the process of finding and connecting to wireless net-works, as well as better use of undocumented features of Android-based smartphones and tablets to interact with ad-hoc net-works. When there is already existing connection to a wireless Wi-Fi network, continuous cyclic scanning other available networks is irrational from the point of energy saving. The primordial features of OS Android determine a one-time connec-tion to a single network. Connecting to ad-hoc network is carried out by specifying a set of static parameters (ip-address, subnet mask, default gateway, etc.) generated by the proposed algorithm designed as a software module. The paper considers one of possible implementations of the proposed algorithm in the Java programming language. Testing of this algorithm was performed on smartphones HTC Sensation and Samsung Galaxy S based on OS Android (2.2–4.1.1). The software module based on the proposed algorithm can be used by developers of network software for solving a wide range of problems con-nected to mobile devices interaction and wireless Wi-Fi networks.

The article considers the question of realization of video surveillance system based on IP-cameras that de-signed for outdoor surveillance. The major factors adversely affecting the video perception are uneven illumination of the observed scene, weather conditions and camera movement. The system provides the opportunity to enhance video stream quality based on nonlinear image enhancement technology with local contrast preserving in bright and poorly lit areas. The usage of non-linear image correction method allows enhancing the quality of the observed scene in the evening and under bad weather conditions. The method of video sequence stabilization based on the corresponding blocks analysis with the spa-tial-temporal post-processing is proposed. There is a possibility to set up preset scene zones that allows increasing algorithm efficiency in the absence of camera movement. To inform the operator about events in a supervision zone the method of mo-tion detection taking into account three types of movement is offered. The video file format archive based on MJpeg stream is designed. It allows keeping information about movement in the frame. The results of experiments for a movement detector are shown. Data of the stabilization effectiveness and increasing the images visual quality obtained in difficult lighting condi-tions are presented.

The article considers the process of pedagogical tests system creation using criterion-referenced approach. The dependence of the estimation accuracy of latent parameters using the Rasch model from probabilistic characteristics of subjects was elaborated. A model of the test specialists description is proposed as asymmetric with respect to zero allocation in a positive direction. The task of minimizing average variance of level of testee expertise estimation in reference to tests har dness is completed. The optimal distribution of task’s easiness for a given distribution of level of expertise was elaborated. The optimal distribution of the tasks for a given distribution of level of expertise was found. The dependence of the optimal distribution of test’s tasks as a deviation from the uniform distribution was found. There is a dependence of tests error variance from the level of testee expertise when uniform and optimal distribution of test’s tasks. The dependence of test’s tasks optimal distribution for a group of subjects with level of expertise symmetrical distribution around zero was elaborated. To minimize the error variance it is necessary to construct a simple test below the average level of testee expertise and more complex tests than the average level. An interval of level of testee expertise distribution should be doubled and aim for uniform distribution.

Simulators are the basis of current combat training for combat units of technical troops subdivisions. These simulators are represented by automation facilities sets and inbuilt software and hardware complexes in relevant radar station. Consequently investment of trainings is high because of the need to activate relevant prototypes of weapons and military equipment while carrying. Besides, carrying of complex trainings on inbuilt simulators is rather difficult. So self-contained simulator creation for technical troops subdivisions is relevant objective. A simulator (in simulated situation) must be in compliance with military equipment prototypes. This article describes a structure and general capabilities of a self-contained simulator «Test» created by R&D Institute «Centrprogrammsystem» (Tver) for technical troops subdivisions. The simulator «Test» provides carrying out of all types of trainings (individual, independent, complex) for combat units of radar-location and radio-technical squadrons fitted with modern digital radar stations. As for structure, the simulator is made as local area network which consists of server, automated working station (AWS) of education chief, automated training working station of radar operator and automated training working station of automa-tion facilities set operators. The AWS of education chief helps to imitate functions which provide educational trainings prepa-ration, training process control, training performance measurement, trainee scorecards maintenance and gradebook mainte-nance. Other AWS in the simulator structure imitate work principles and information models that are in compliance with princi-ples and models of real issue type. It simplifies the transition from a simulator to military equipment. The simulator «Test» has gone through official test and is recommended to batch series line production.

The article offers the new indicator of engineering-economic analysis and the choice of ground-based radar al-ternate design. It based on indicators convolution of tactical technical specifications (output performance) and maintenance engineering specifications. The article shows how difficult is engineering-economic analysis of ground-based radar alternate design for aerial objects detection and upgrading the existing radar stock. This difficulty connected to the need to use a lot of different indicators for evaluation. When solving multi-criteria and multivariable tasks and combining special indicators into one there is subjectivity of an experts group. Using linear search of radar parameters for estimation is time-consuming and of-ten gives questionable result. To speed up an enumeration of possibilities and to simplify the choice of preferred alternate, new indicator is developed. It allows eliminating uncertainty when making final decision. Offered indicator of engineering-economic analysis and the choice of ground-based radar alternate design based on quantitative assessment of the potentials for radar which implemented in a detection area formed using radar energy characteristic (detection range, positional accuracy, interference resistance); maintenance engineering using that determines possibilities of radar combat capability realization. They include: reliability characteristics (faultlessness, serviceability, endurance), radar cost performance (development, production and direct operat-ing costs) and finance resources depending on element base, radar design features, repair suitability and so on. This method is useful when upgrading existing radars and designing new air surveillance radars.
