Cascade Structural Encoding of Binary Arrays
(EWDTS, 2008) Barannik, Vlad.; Hahanova, A. V.
The lacks of existent approaches come to light in relation to the compression of binary data for their use in digital diagnostics. It is grounded, that due to presentation of binary array as integral structure as a cascade structural number, satisfying limits on the number of carouses of units and on the dynamic range of cod-numbers of OFSN additional reduction of structural surplus is provided. The basic stages of binary of a two stage cascade structural encoding are expounded. Proved, that amount of digits on presentation of binary column examined as an element of cascade structural number less than, than amount of digits on presentation of that column, but examined as an onedimensional floating structural number. The features of treatment of diagnostic information consist of that: on treatment test sets, having an arbitrary structure and different statistical descriptions, are given; test information appears in a binary kind; the lead through of diagnostics of digital charts is carried out on the basis of the kept test sets. Digital diagnostics means related to the increase of volumes of test information. From here is the scientifically-applied task, consisting of diminishing of volumes of test information.
Coding Tangible Component of Transforms to Provide Accessibility and Integrity of Video Data
(EWDTS, 2012) Barannik, Vlad.; Hahanova, A. V.; Krivonos, V. N.
Renders a decision upon further development of compression technologies for transformed images in component representation. Demonstrates description model for transforms tangible components on the basis of positional numbers with unequal adjacent elements. Outlines the basic steps of positional coding to reduce total costs associated with representation of transforms tangible components. To this effect, a system of coding expressions to compress video data accuracy and integrity lossless is developed. Problem Statement and literature analysis. The development of modern society has a peculiar feature – dependence on the increased consumption of video data. Thus demanding to provide appropriate requirements for reliability, availability, and integrity of the video data. One of the crucial points when meeting these requirements is video data source coding [1 - 3]. This proves the timely character of relevant scientific and applied research in the field of digital image compression. The analysis of compression systems has shown that the most effective process is provided for pre-transformed images [3 - 5]. However, elimination of redundancy in transforms is carried out mainly by taking into account psycho-visual and statistical laws. As a result, there is a limited level of compression and a sharp drop in reliability of decoded video data. Thus, the objective of the research is to develop the method for coding segment image transforms that will provide increase in availability and integrity of video data for a given level of reliability.

Hierarchical Systems Testing based on Boundary Scan Technologies
(EWDTW, 2006) Hahanov, V. I.; Melnik, D.; Yeliseev, V.; Hahanova, A. V.
We propose models of complex program-technical systems testing; these models solve diagnosis tasks in real time. Models use IEEE standard boundary scan technologies to observe internal lines, and methods of testability evaluation to define critical places in digital objects. Models and methods are oriented to test distributed control systems of critical technologies. Basic requirements for modern informational and control systems for complex objects and critical technologies are: 1) provide high reliability during operation; 2) online monitoring and control of all the parameters of critical system of object; 3) testing, diagnostics and repair in technically and standard acceptable time; 4) provide desired diagnosis depth of system or its components, automatically and in real time. New generation of modern technologies and design flows introduces additional criteria, related to design, manufacture and operation of digital devices: time-tomarket, Design-for-Manufacturability, Testability, Diagnosis, Verification. Major design stage is verification process, aimed to eliminate all design errors on the early stages; it leads to considerable time and costs savings. Acceptable testable overhead (assertion), added at early design stage, is interesting here, because it considerable decreases main parameter – time-to-market, using verification and testing methods; it is very urgent and attractive design model. Talk is about use of verification test, obtained at system design stage, to check device with minimal additional hardware and software expenses using boundary scan technologies. At the same time, hardware/software overhead mechanism must include additional control points, which must be introduced into design using Boundary Scan Register of special (ad-hoc) technologies at synthesis stage. As a result, design redundancy created once maybe used many times to check components of digital system during all stages of its lifecycle. At present, complex digital devices are considered as objects with several levels of hierarchy. At the lowest level, system is represented as a set of modern integrated circuits (PLD, ASIC), which implements SoCs, NoCs, memory, processors. Second level is formed by system on boards, where integral circuits are represented as primitives. Third level represents set of boards, which integrated into crates. Fourth level combines set of crates or boxes into complex distributed control system of technological process, manufacturing or critical technologies (aviation, cosmonautics, nuclear-power engineering, meteorology, defense, ecology). Fifth level may be considered as geographically distributed system, e.g. Internet. In this research, we consider from first to fourth levels of hierarchy, in order to creation of models and methods of its testing with defined diagnosis depth. Research objective – considerable decrease of complex digital system testing time during operation based on creation of general model of organization and execution of diagnostic experiment, including unconditional algorithms of faults finding using IEEE standards of testable design. Research problems: 1) choosing appropriate methods and tools for testing of all mentioned levels of hierarchy; 2) development of hierarchical model of organization and execution of diagnostic experiment, including conditional and unconditional algorithms of faults finding, oriented to testable design standards; 3) practical implementation of complex digital devices testing models and experimental evaluation.

Construct a modified non-equilibrium position coding, based on code generation from the younger elements and implementation of cross-order correspondence between the OP number elements and array elements column of the run lengths binary elements. Creates a method of decoding the modified nonequilibrium position in the direction of the senior members on the basis of considering the possibility of forming weights, beginning with the junior members.
Models for Quality Analysis of Computer Structures
(EWDTS, 2012) Murad, Ali Abbas; Chumachenko, S. V.; Hahanova, A. V.; Gorobets, A. A.; Priymak, A.
The methods for estimating computational structures and searching the shortest paths between the pair of nodes are presented. A criterion for evaluating the effectiveness of computational structures based on the graph model of the functional blocks of digital systems-on-chips is developed. A modified Dijkstra's algorithm to determine the average cost of interconnections in computing architecture for every pair of nodes is proposed. Verification of the criterion, when evaluating the effectiveness of different topologies of computational structures is performed. Creating effective computational structures is related not only to increasing the speed of primitives, but also with the topology of interconnections between them, which can significantly improve the performance of parallel processing data due to additional expensive connections. It is therefore necessary to have criteria for evaluating performance, taking into account not only transaction time between the nodes, but the hardware redundancy, which considerably reduces the average time of receiving and transmission of information between the primitive computing components. Such criteria can be used to evaluate the effectiveness of graph models of local and global computer networks, urban infrastructure of road communications, as well as the traffic flows in order to identify bottlenecks affecting the traffic. The problem of finding such criteria is related to the minimization of the computational cost for determination of all possible minimal paths between nodes of pairs. The aim of research is development of criteria for evaluating the effectiveness of computational structures, based on graph model of interconnections of functional blocks, which make it possible to determine the quality of the topological architectures of digital systems-on-chips. The objectives: 1) Analysis of methods for estimating the computational structures and finding the shortest paths between nodes of pair. 2) Development of criteria for evaluating the effectiveness of computational structures, based on graph model of the functional blocks of digital systems-on-chips. 3) Modification of Dijkstra's algorithm to determine the average cost of interconnections of computing architecture for a node pair. 4) Verification of the criteria when evaluating the effectiveness of different topologies of computational structures.

The theory, methods and the architecture of parallel information's analysis is presented by the form of analytical, graph and table forms of associative relations for the search, recognition, diagnosis of destructive components and the decision making in ndimensional vector cybernetic individual space. Vector -logical processes-models of actual oriented tasks are considered. They include the diagnostic of spam and the recovery of serviceability, the hardwaresoftware components of computer systems and the decision quality is estimated by the interactions of nonarithmetic metrics of Boolean vectors. The concept of self-development information of computer ecosystem is offered. It repeats the evolution of the functionality of the person. Original processes-models of associativelogical information analysis are represented on the basis of high-speed multiprocessor in n-dimensional vector discrete space. The problem of creating an effective infrastructure of cyberspace (Cyber Space), as well as selfdeveloping information and computing ecosystems (ICES) of the planet is particularly important for global companies, such as Kaspersky Laboratory, Google and Microsoft. Cyberspace as an object of nature is also susceptible to destructive components affecting the performance of subjects, which are computers, systems and networks. Therefore, now and in the future it remains as an important problem of space standardization and specialization of all the interacting entities, including the negative, as an integral part of the ecosystem. This action is permanent in time, whose purpose is to keep up, but one step ahead of the emergence of new malicious components, by creating an infrastructure cybernetic space, operating the computer ecosystem of the planet and the quality of each person's life.
Technology of Cascade Structural Decoding
(EWDTS, 2009) Soroka, L.; Barannik, Vlad.; Hahanova, A. V.
The necessity of increase of operationability of renewal of information is grounded without errors in the systems of digital diagnostics. Proof of theorem is conducted about decoding of code-number of cascade structural number. As a result of the well-proven theorem correlations are built providing renewal of elements of binary cascade structural number for the set official information without bringing of errors. The basic stages of process are expounded renewals of binary information on the basis of the cascade structural decoding, plugging in itself the system of expressions for recurrent determination of value of initial gravimetric coefficient of column of cascade structural number. Technology of rapid renewal of elements of cascade structural number is built without implementation of decodings actions. For the increase of operationability of communication of data in the informativelytelecommunication systems it is necessary to carry out their compact presentation [1, 2]. It results in diminishing of digital volumes of information, and consequently, and to diminishing of amount of packages of information. Important requirements to the methods of compression it is been: increase of degree of compression; providing of control of the errors given without bringing; decline of time of treatment. Thus in a number of practical applications, in that numbers in the process of diagnostics of digital charts, it is especially important to carry out rapid renewal of information. For existent approaches in organization of compression and renewal of binary information the additional increase of coefficient of compression is or with the loss of information or with the increase of temporal expenses on treatment [1 - 4]. From here the scientifically-applied task is a decline of time of renewal of information at the maintenance of the required level of authenticity of information. The method of compact presentation of binary information is in-process [5] developed with arbitrary statistical descriptions. It is rotined that approach, based on forming of cascade structural code combinations, allows to promote the degree of compression. In also time for the use of this method in the handling systems of data it is required to carry out their timely renewal without bringing of errors. Means the purpose of researches is in developments of method of rapid renewal of cascade structural numbers (CSN) without bringing of error.
The Positional Structural-Weight Coding of the Binary View of Transformants
(EWDTS, 2012) Barannik, Vlad.; Krasnoruckiy, A.; Hahanova, A. V.
This paper investigates the peculiarities of the coding transformant bit view taking into account the observed regularities of binary structures based on the positional structural-weight (PSW) coding. It is proved that the technology of the PSW coding has two mechanisms for compensation of the influence of structural characteristics of a transformant binary format (the quantity of bits of compressed views per one element in average). The mechanisms of compensation are a formation of lengths for binary series and a building system of PSW number bases for each array of lengths of binary series. The development of InfoComm systems is realized in accordance with the conception of creating nextgeneration nets (NGN). The bulk of expansion of services is linked to providing of multimedia information [1; 2]. The conducted analysis of characteristics of video-information providing using InfoComm systems has shown that the given time of a transfer is provided only for images with the low spatial allowing. To overcome the current imbalance between the time of giving images and necessary time, the reduction of the rate allowing of video stream using compression systems should be provided. The analysis of approaches of building video compression systems in the infocommunications has revealed that they are based on using JPEG oriented technologies [3-4]. Owing to the fact that using compression systems for a transfer of images with normal SD quality for high-rate communication channels, if there is a loss of quality of the reconstructed images at the level of the peak signal-tonoise ratio equal to 30 DB. The existing image compression technologies using the JPEG-oriented technologies do not provide the required level of bit rate of compressed video stream. Therefore, lowering of the bit rate of the compressed video data to improve the quality of telecommunication services is the relevant scientific-applied task. Lowering of the bit rate of transformed images is requested to provide improving technology of the coding of a binary view. This technology has the potential to reduce bit stream and time of processing transformants in condition of the given quality of image reconstruction for various degrees of a saturation of small objects. The process of compressing of the transformant n ,mY (transformant is examined at the bit level of descriptions) is contained in identification of regularities of binary structures. Therefore, it is necessary to justify the conceptual approach to a system of changes consisting of the following components [5]: 1) making components χ ξ,y of a transformant by binarization; 2) identification of structural regularities for the binary view of a transformant 2 n,m ]Y[ ; 3) coding of a bit view of a transformant taking into account the observed regularities of binary structures. It is also required to provide: - lowering of the bit rate ( c v ) of compact transformant view without making additional distortions; - decreasing the quantity of transactions to process of a transformant. The aim of this research is to develop the coding of a bit view of a transformant to increase the compression degrees of images (in consider of conservation of the specified image quality) intended for a transfer in InfoComm systems in real-time.
Video Decompression Technology in Information and Communication Technologies
(EWDTS, 2014) Ryabukha, Yu.; Krivonos, V.; Hahanova, A. V.
It is proposed to introduce new methods of video data compression for more efficient use of wireless technology. Therefore, we propose the method of reconstructing digital static images based on the restoration of transforms. There is a technology of renovating values of vector of significant subbands of the nonuniform DCT spectrum on a known code and base; the vector of scaling components based on the decoding of the first zero series and Bodo codes; lowfrequency DC component using a statistical code. The decompression method proposed allows restoring an image without making the information loss for a given confidence level. An intensive growth of video data, which significantly advance the production capacity of the existing wireless telecommunication systems, generates a need in their compact representation. Existing methods of video data compression, according to the characteristics of the compression ratio, allow transmitting images in real time, however, with a significant loss of quality. One of the areas that can improve the performance of existing wireless technologies in transferring and processing video data is based on the introduction of new methods of compression, which, in turn, will reduce the cost of technical modernization of telecommunication systems. Hence, the development of video coding method to reduce their volume in telecommunication systems is an actual scientific and application task. Therefore, we propose method of compressing video data with controlled quality loss based on JPEG platform [1, 2]. This allows to reduce the amount of information at the desired level of reliability of the image. Image processing starts with changing the RGB color model to YCrCb model, with further segmentation, i.e. partitioning the image into blocks of 8 × 8 pixels. Further, a discrete cosine transform is applied to each block (DCT). Then, quantization and non-uniform decrease of DCT coefficient values are applied to the DCT transform. The next step is the formation of dimensional vector of n Y component from the transforms using diagonal scanning. A lowfrequency DC component is allocated individually from the one-dimensional vector formed, and the vector of significant n 1 Y − subbands and the vector of scaling 1 nG − components are formed from the remaining components. Vector of significant subbands is a sequence of non-uniform values of DCT frequency spectrum. Components of the vector n 1 G − indicate the length of the corresponding sub-band. This method allows gaining an advantage over the JPEG standard, regarding the processing of medium and highly saturated images. In addition, there is a need in reconstructing an image, which won’t exceed the complexity of coding and will restore the image without making mistakes. Hence, the objective of research is to develop a method for the reconstruction of compressed video data using the pre-transformation.
