Under the received data it is possible to draw a conclusion that for qualitative crops and formation of the form of a bed working-organ should will plunge into soil in limits to 2,0 ... 4,0 sm; for formation of slightly condensed form of a furrow in the course of work should be constantly pressed to a row-spacing surface; to provide not over turning soil small groups through wings work-
ing-organ with optimum height within 14 ... 18 sm; the corner of installation of wings in a longitudinal direction of movement working-organ equal a=47 ° is the most favorable; the corner of a solution of wings working-organ, equal y=69 ° is optimum; results of researches are introduced in educational process, as the methodical grant for master degree.

Development of technology integrated design form a unibody clothing details
Abstract: In the article the results of research conducted on the development of technology complex a consistent single-process designing of fabrics and details of garments, including all stages of a single system for design documentation.
Keywords: complex designing, formation, weaving, technical project, a sketch and technical projecting, design stages, subsystems, structure designed fabric, integrally form a semi-finished parts of clothing.
The most important condition for the effective functioning of the industry in general is the optimum ratio between its industries, a diversified and balanced development of the vertical and horizontal, in particular, the introduction ofnew innovative technologies in the design and manufacture of products of light industry [1].
Classical methods of designing and manufacturing clothing from woven materials focused primarily on the use of its production already existing range of fabrics. Nowadays fundamentally new methods of creating clothes, based on an integrated approach
to the design of material for clothes and most clothes, requiring a fundamental change in technology design and creation of fundamentally new equipment for its manufacture. Among them: production of parts and units sewing products a cut from one piece of semi-finished on special equipment using the formability of tissues [2-4], getting integrally of woven garment components directly on the weaving equipment, methods using direct digital printing while receiving fabric, knitted fabrics and details or samples clothes from her and some other [5-9]. These methods are highly efficient
Development of technology integrated design form a unibody clothing details
manufacturing clothes, saving raw materials, reduction of numerous manufacturing operations at various stages of production sewing products, the expense of what significantly reduced their labor input and prime cost [10].
The task designing of complex semi-finished products contain a substantial amount of heuristic elements, common methodological recommendations without a precise quantitative description of the parameters, resulting in the need to improve the project as a result of manufacturing products. Development of a new methodology for the design of individual procedures should be based on the systematization, formalization and reliable results of research, composition and structure of a number of factors that influence the design parameters.
Integrated design in our case is kinds of technology, system design, determine the functioning of the system design integrally the formed semi finished of clothing details (IFSCD), as it provides for the consideration of the whole process, from the identification of needs in IFSCD to finished products. The tasks at all stages of the process in accordance with the principles of the system approach are subject to a common goal — to create such a product on the basis
of IFSCD that would ensure maximum satisfaction of consumer demands. Concurrently the minimum production cost of manufacturing should be provided IFSCD:
max min E/y, z/ - npu xeX; y=Y, x=X at x < X0, where E — the usefulness products of clothing; z — consumer requirements; y — production requirements; X — the parameters of the weaving equipment; X0 — the existing limitations associated with the possibilities of weaving equipment.
As a result of this task the designer receives the set of feasible solutions satisfying the system constraints, including the possible existence of one or more solutions that provide optimum value E.
This complex multi-objective problem can be solved with the help of System Studies envisaging the construction of a common conceptual model of the process. At the same time, this system will include the main stages of solving design problems and characterization stages, clarifying the functions of each stage of the design process and their further detail, as well as the definition of functional interlink ages between the characteristics and objective functions of the design process in all its stages and for the whole process.
Picture. Conceptual functional-block model of the design process IFSCD
The basis of the separation of the design process IFSCD on stage as well as for the clothes put the typical staging defined by single system design documentation (SSDD). The illustration is a conceptual diagram IFSCD clothing design system, which determines the sequence of the main stages ofthe design and conditions of interaction of managing and providing subsystems, integrated functional process (look at the picture). The diagrams are adopted following conventions: IR—initial requirements; TT — technical task; TP — Technical proposal; PD — preliminary design; TP — technical project; DD — detailed documentation; block 1 — assessment of the output parameters of functional processes under; block II — the corrective control action.
The process of designing IFSCD is presented as a set of interrelated stages of decision-making.
Thus, it can be concluded that the task of building a rational structure of the design process IFSCD based on research and analysis developed by graphic relationships presented above has been solved with the help of systems research. At the same time it is planned to build a common conceptual model of the process, clarifying the functions of each stage of the design process and their further detail, as well as the determination of functional relationships between the characteristics and objective functions of the design process in all its phases and for the whole process.

Application scaling methods to improve TV images data compression
Abstract: In this article, the method of increasing the efficiency of the compression of the video stream compression based on the pre-encoded reduce image size is given. The effect of conversion images into the YUV form to compression efficiency are described in detail. Experimental information of reconstructed images' RMSD is presented. The effect of the aperture on the quality interpolators restore the decimated image and evaluate the effectiveness of their work Some words about LeGall wavelet filter are given.
Keywords: image, compression, redundant information, codec, video stream, compression ratio.
When transferring the television broadcast signal into digital form, it is generated digital data stream with a bit rate of about 240 Mbps, for transmission of which the 120 MHz bandwidth links are required transmission links with a bandwidth of 120 MHz. However, standard TV channels have a bandwidth of 8 MHz, so to adjust the signal parameters with the parameters of communication channel special methods of compressing the volume of digital data of audio and video data are used. Moreover, under conditions of given the limited frequency resource it is economically advantageous to transfer by one TV channel as much as possible on one TV channel TV programs, but without any significant deterioration in the quality of image and sound. Therefore,
the efficient compression problem of TV image signals efficient compression TV image signals is has a great practical importance.
Compressing the volume of video data is usually done by removing the redundant information of the following types: code, inter-element or statistical, psycho visual, temporary or structural inter-frame [1]. It should be noted that in the MPEG TV main compression standards MPEG main video compression is achieved by eliminating inter-frame redundancy, as a movie in a single video scene an interframe differences of adjacent frames is, usually small. (Fig. 1). Two adjacent frames (a, b) and their difference (c) are showed in figure 1.
