Background: In the increasingly large scale of the current multimedia information database, as described in various patents, big data technology is becoming more and more mature, and the problem of massive multimedia data mining is becoming more and more important. Method: In order to solve these problems through the analysis of the status for multimedia data mining, the general system structure in the application of multimedia information mining technology is analyzed, and the different methods and principles of text mining, image mining, video mining, web data mining in multimedia information data mining are made detailed analysis and the advantage and disadvantages are contrasted. Through the design of different experiments, the effectiveness and inferior of different methods are verified. Result: In the improved algorithm, the mining result of the multimedia text data based on correlation analysis is very different from the actual multimedia text data, the result is closer to the original mining image result, so this method is more practical. Conclusion: Through the summary and discussion on the problems existed in the current method, the faced challenges of multimedia information data mining technology are pointed out, to lay the foundation for the further development of the related technology. © 2017 Bentham Science Publishers.

The control systems of multi-channel multiphase queuing systems are considered. The control system is based on the methodology of optimal aggregation, therefore there are no restrictions on the form of the functions "costs, output" and probability distribution functions. The methods of optimal aggregation solve the optimization problem for continuous, discrete and integer functions of the class "costs, output". Processes for servicing the flow of objects has two modes: the absence and presence of queues. Software modules for analyzing and predicting of the requirements flow, optimal service in the presence and absence of queues are developed.

Lyapunov-Function-Based Control Approach for Three-Level Four-Leg Shunt Active Power Filters with Nonlinear and Unbalanced Loads

作者： S. Sajjad Seyedalipour Sertac Bayhan Hasan Komurcugil Faculty of Electrical Engineering K. N. Toosi University of Technology Tehran Iran Department of Electronics and Automation Gazi University Ankara Turkey Department of Computer Engineering' Eastern Mediterranean University Turkey

This paper presents a control method for three-level four-leg shunt active power filters (SAPFs) based on Lyapunov's stability theory. The dynamic equations of the SAPF will be achieved and then transformed into the dq0 frame. By considering the nonlinearity of the obtained equations, the Lyapunov technique is used in order to find a solution to enhance the system stability. The design in this approach is to define an energy function in terms of the system states and after that ascertain the control rule that makes the considered function derivative always negative under all conditions. By the use of the proposed method and determining the appropriate reference currents, the SAPF provides compensation for reactive, harmonic, neutral and unbalanced current components generated by grid-connected loads. The accuracy of the proposed control approach is validated via MATLAB/Simulink software.

In the present paper will be discussed the problem related to the individual household electric power consumption of objects in different areas – industry, farmers, banks, hospitals, theaters, hostels, supermarkets, universities. The main goal of the directed research is to estimate the active P and full S power consumptions for all studied buildings. The defined goal is achieved by solving of the following three problems. The first problem studies which buildings increase their power consumption. The second one finds which objects have the greatest increase of power consumption. And the third problem regards if it is possible to make a short-term forecast, based on the solutions of previous two problems. The present research and solving of the aforementioned problems is conducted using fractional Brownian motion theory. The applicability of this approach is illustrated on the example with 20 real objects in different areas. The paper ends with conclusion notes about possibilities to make short-term forecasts about power consumption of the considered buildings. © 2018, North Atlantic University Union.

This paper deals with mobile robot localization purpose. The presented solution is designed for indoor environment only. GPS navigation system cannot be used in environment inside of buildings. Alternative methods have to be used for this purpose. The mobile robot localization is essential part of autonomous mobile robotics. Mobile robot localization together with odometry is necessary for mobile robot navigation. Presented paper contains explanation of localization approach, which is based on probabilistic method. Next part of this paper is description of experimental odometry method, which is based on computer vision. © Springer International Publishing AG 2017.
