CALCULATION OF GF (P) ELLIPTIC CURVES IN FPGA Marek Aleksander 1), Mykola Karpinskyy 2), Grzegorz Litawa 1)
1) State Higher Vocational School in Nowy Sacz, Poland, The paper describes a hardware system carrying out point summation on elliptic curves. The implementation of basic function, which is modulo multiplication of huge integrals, is based on Krestenson’s basis. Such a summing unit has been used for hardware implementation of Pollard rho-algorithm. The paper also presents the performance of the mentioned unit.
THE METHOD OF SOFTWARE RELIABILITY EVALUATION AND Maksym Seniv, Vitaliy Yakovyna, Yaroslav Chabanyuk, Dmytro Fedasyuk
Lviv Polytechnic National University 12 Bandery St., Lviv, 79013, Ukraine The software reliability evaluation and prediction method based on the model with dynamic index of project size is examined in this article. The support decision making procedure during software production which is based on the adequacy criterion of software testing is developed. The example of developed method based on testing data of industrial software product is proposed. NEW APPROACH TOWARDS EFFICIENT BIOMETRIC SYSTEMS Chander Kant
Kurukshetra University Fingerprints possess two main types of features that are used for automatic fingerprint identification and verification: (i) Ridge and Furrow structure that forms a special pattern in the central region of the fingerprint and (ii) Minutiae details associated with the local ridge and furrow structure. In a traditional biometric recognition system, the biometric template is usually stored on a central server during enrollment. The candidate biometric template captured by the biometric device is sent to the server where the processing and matching steps are performed. The proposed work presents an approach to the processing time during fingerprint matching process in a Biometric System. The proposed work is based upon four major classifications of fingerprint, whorl, arch, left-loop and right-loop and is more efficient as compared with the existing system. EDUCATION INTELLIGENCE SOFTWARE AS A TOOL OF INCREASING THE EFFECTIVENESS OF CREATIVE LEARNING

1) Boris Grinchenko Kyiv University, A mathematical model of learning in the way of self information-educational activity of a student is developed in his article. A method for constructing and optimizing of individual educational trajectories is proposed. The impact of the use of specialized information and analytical systems on quality scores of the learning process is analyzed. This paper introduces the concept of Education Intelligence systems and shows that their use in an education process is a powerful tool of the intensification of the training activities.
UNSUPERVISED TEXTURE CLASSIFICATION OF ENTROPY BASED S. S. Sreeja Mole 1), L. Ganesan 2)
1) Department of Computer Science and Engineering, This paper presents an efficient approach for unsupervised Texture Segmentation and Classification, based on features extracted from entropy based local descriptor using K-means clustering with spatial information. The K- means clustering algorithm is commonly used in computer vision as a form of image segmentation. Texture analysis refers to a class of mathematical procedures and models that characterizes the spatial variations within imagery as a means of extracting information. Texture analysis may require the solution of two different problems first is Segmentation and Classification of a given image according to the different texture and second was for of a given texture with respect to a set of known textures. Based on the proposed concept, this paper describes the entropy based local descriptor using K-Means with spatial information approach. Experimental results show that the proposed framework performs very well compared to other clustering algorithms in all measured criteria. Spatial information has been effectively used for unsupervised texture classification for Brodatz of texture images. The model is not specifically confined to a particular texture feature. We tested this algorithm using other texture features. The proposed entropy based local descriptor approach gives good accuracy when compared with other methods.
SEGMENTATION OF VESSELS IMAGES ON ANGIOGRAMS Marina Polyakova
Odessa National Polytechnic University, The method of vessel segmentation on angiogram is elaborated. It includes the analysis of own values of Hessian for every pixel of image. The elements of Hessian calculated from the image convolution by the common wavelet functions with a compact support. This decreases the conputational complexity of method of segmentation of angiograms due to replacement of a few levels of data processing by one.
A METHODOLOGY FOR DATABASE Raj Gaurang Tiwari 1), Mohd. Husain 1), Anil Agrawal 2)
1) Azad Institute of Engineering and Technology Lucknow (UP), India
As web users are facing the problems of information overload and drowning due to the significant and rapid
growth in the amount of information and the number of users so there is need to provide Web users the more exactly
needed information which is becoming a critical issue in web-based information retrieval and Web applications. In this
work, we aspire to improve the performance of Web information retrieval and Web presentation through developing
and employing Web data mining paradigms.
RESEARCH OF OBJECTIVE FUNCTION IN PARAMETRIC Mykola Dyvak 1), Taras Dyvak 1), Petro Stakhiv 2)
1) Ternopil National Economic University The paper presents the problems of parametric identification of nonlinear difference operator based on interval data. It is shoed that, formally, this problem belongs to the task of finding at least of one solution of interval system of nonlinear algebraic equations. It is proposed and justified the use of the methods of random search with a nonlinear discrete criterion function for solving this task. The properties of the function are researched in this paper.
GAME-THEORETICAL MODEL APPLICATION’S TO PLANNING AND Jan Kałuski
Silesian University of Technology, Gliwice, Poland The game-theoretical approach to the planning and management of materials needed for the mining enterprise is presented. The hierarchical two-person game with non-zero-sum was developed and justified. For the pure strategies of two persons-players (a government and its laws from one side, and a mining enterprise from another side) a game – decision was selected in a form of the Stackelberg optimal strategies. A scenario of the proposed game has been verified on the example of real data from the coal mine. RELATIVITY INDEX OF THE RELIABILITY OF SPACE SYSTEMS Nikolay Petrov
Technical University of Sofia, According to the special theory of relativity by Einstein, it can be affirmed that two events coincide in space only when objects are shown (or system of objects); according to latter the position of these events is defining. In this way the term “position in space” is relative too. When we talk about the position of one object in space – it’s actually its position among other objects. However, if we have to give answer to the question “where is the current object?” without mentioning about the condition of adjacent objects, it follows that this question will be meaningless. In this article has been done a trial for taking of theoretical dependence, which defines the probability for no-failure of mobile space systems (spacecraft), moving with determinate speed towards an observer on the Earth. AGENT BASED ACCESS TO HETEROGENEOUS DATABASES Vyacheslav Y. Pysmennyi, Maksym Y. Ternovoy
National Technical University of Ukraine “Kyyiv Polytechnic Institute” The paper presents the implementation of system for access to the information in distributed information- telecommunication environment with heterogeneous databases using multi-agent approach. Different ways for multi- agent system construction were considered. It was developed a scheme of interaction between agents in the proposed system. The approach aims to improve the efficiency of data access in heterogeneous information systems without the necessity to change them. /p> |
