The article is dedicated to the problem of a text sentiment analysis using a dictionary method. The sentiment analysis is used in many areas, for example, in the marketing research, the recommendatory systems, the search engines, the human-computer interaction, the news analysis, etc. The dictionary method along with machine learning is one of the most effective approaches to the sentiment analysis. The dictionary method is based on the sentiment lexicon; each word from this lexicon has a weight indicating the degree of the word importance. The quality of text sentiment analysis depends significantly on the correct assignment of the words’ weights. This paper proposes a new method for assignment of the words’ weights. The problem of the weight assignment is considered as a multi-dimensional function optimization task. The arguments of the function are the weights of words; the values of the function are the some metric of the quality of sentiment analysis. This metric is obtained from dictionary method with given weights. In this paper the metric is F1‑measure. The optimization problem is solved using a genetic algorithm. The experiments were carried out on a collection of movie reviews from the seminar ROMIP‑2011. The results demonstrate the advantage of the proposed method of weight assignment over other ways, as well as the superiority of the dictionary method over the support vector machine.

The surface plasmon resonance (SPR) technique is used to detect a considerable change of the dielectric constant of a silver film when a constant voltage is applied to a MDM nanostructure. The structure looks like a capacitor with Ag films 49 nm and 37 nm thick as capacitor plates and a 177-nm Al2O3 film as the dielectric. The effect is a significant change of light reflectance when applied voltage is up to 30 V across the electrodes. A good match between the theory and experiment can be achieved with the assumption that the optical properties of silver change differently at the cathode and the anode, and the Al2O3 dielectric layer begins absorbing the light. The refraction of the cathode silver layer is shown to become zero when the voltage is greater than 16 V

The article considers the method of system analysis of decision making for creating an electronic workflow system. This method is based on the principle of coordinated management and the laws of coordinated planing, it includes heuristic procedures and fuzzy logic. Informal procedures of project management for electronic workflow system are developed.Formalization and formulation of a decision-making problem in vague conditions with vague coalition is also executed. Vagueness (fuzzyness) is one of the main uncertainties in the processes of coordinated optimization. Decision-makers are mainly use vague concepts and perform vague instructions. Besides, these people have different points of view considering problem solving. That is why a decision is often made under conflict. To reduce conflict situations when developing software, it is offered to use well-known methods of coordinated control and planning as parts of system analysis method. The differences in purposes, views and interests determine a necessity for the formation of new principles of creating information-control systems of decision making support.

The article considers the issues of 3D graphical representation of operational and geometric characteristics of fuel elements and fuel assemblies of VVER-1000, which are implemented in Fuel Elements Data System software. The paper proposes modern approaches to writing an application with a graphical user interface, which implements the Firebird database client, based on open software libraries such as Nokia Qt, QwtPlot and GLC_lib. Thus, using these tools allows creating a number of new features in charts constructing, including: easy chart scaling and automatic setting the limits on the coordinate axes. The main tool in the design of the visualizer window interface was GLC_lib software library. It provided features for the displaying assembly of fuel elements, including the functions to control the position of the three-dimensional scene camera, lighting, texturing and color. Any object in the scene can be selected by a cursor. This software library within Nokia Qt SDK which includes Nokia Qt Creator software environment, provides additional functional features for developing software product.Special attention is paid to problems of representation information extracted from the database.

One of the main criteria for providing highly realistic images when Earth model is rendered in the simulation-training complexes is to use Earth's detailed surface texture in visualization process. This paper proposes such texture preparation technology from initial set of same size tiles (photo images of Earth's small surface area). This texture can be subsequently used in applications that visualize Earth models and use distributed computing as well as ultra-large texture technology. The article consideres the decisions of the most important tasks regarding the described problem. Since original tiles are usually set in the Mercator projection, the algorithm is proposed to transform Mercator projection texture to equidistant cylindrical projection texture which is easier to use hereinafter. Also the way for seamless adding water surfaces to prepare texture is described if they are absent in the original set of tiles. It includes using special grayscale mask texture. The method of such a mask creation is proposed and described in one of the sections of this article. In addition, in the paper describes the software complex that has been created based on proposed technologies, methods and algorithms. This complex consists of three applications for Microsoft Windows operating system and one script for the Adobe Photoshop program. They allow user to prepare a required texture of Earth’s surface in a few steps.

International civil aviation organization (ICAO) has developed a Manual of Criteria for the Flight Simulation Training Devices Qualification (Doc 9625). This guide was created for civil aviation authorities and is aimed to provide methods of flight simulator qualification using initial and recurrent evaluations of the simulator. The document “Flight Simulator Design and Performance Data Requirements”, 7th edn, issued by the International Air Transport Association (2009) is related to the Doc 9625 and defines the requirements to the set of initial data (Data package) for the simulator design. In addition to the standards there is a technical guideline for the qualification – “Flight Simulator Evaluation Handbook”, vol. 1, 4th edn, Royal Aeronautical Society, London 2009. It includes descriptions of tests sequence necessary for correct certification. Similar documents have already been developed in Russia. After the simulator construction the developers must check if the simulator matches the real device. Up to 80 % of the project development time is spent on testing the mathematical model of object. It is quite difficult to reproduce all actions of the real system operator on the simulator. In this situation, automatic signal input can be used for simulator testing with data from the real system. It is necessary to pay attention to the fact that after assigning a certificate of a certain level by the FAA or JAA standards to the trainer, introduction of changes to the elements design, software, etc., including updating the components of the simulator, can lead to changes of all the systems characteristics. The simulator may cease to comply with the earlier assigned level. The information in this article is intended for organizations-developers, designing an architecture of the training systems.

The article describes the usability problem of ergatic management systems (ESA) as a component of the interaction between an operator, an object, environment and control systems in data-processing systems. The most important component here is the solution of creating a complex human-machine interface (HMI) problem using dual principle which maximally takes into account a human factor – psychological, physiological and anatomical aspects of human-computer interaction with the full range of functional problems solved. The research on digital computing systems with artificial intelligence becomes particularly relevant for human-machine interface and computer control. The main motivating reason for the creation of such systems is the security with its high intensity in the modern world. The development of this direction involves fundamental changes in the functional structure of the management process, the creation of the necessary theoretical basis for formulating and solving specific scientific and engineering problems. In this regard, one of the most important design issues of high ESA is the optimal distribution of functions between PR and technical means considering the psycho-physiological capacities of a human. This kind of work is based on the feasibility provided by existing automation devices and computer equipment. The novelty and prospectivity of implementation of the proposed approach is defined by the results to design and build, where a key part may be a prevention of psychological and physiological factors. The creation of a complex system using a dual principle allows implementing the urgent tasks of the human-machine interface organization considering the intellectualization of human-machine complex, construction and development of automated information management systems and diagnosing psychological and physiological security of a person.
