Russia lags behind most of all the parameters that characterize the relationship of factors of the innovation system. National innovation system - a set of actors and institutions, which are aimed at implementing and supporting the implementation of innovation. Its development involves the use of a broad range of instruments, such as technology clusters, venture financing, and other parks. It is necessary to collect on the same site business representatives and researchers to establish a dialogue between them, to identify common ground and common interests. Creation of production and technology and innovation clusters, industrial parks, technology-innovative zones contributes to the formation mechanisms coordinated interaction of subjects of innovation activity on the basis of cooperation and integration, improving the competitiveness of the socio-economic systems and regions.

The article discusses the Pan-Tompkins algorithm to detect QRS complexes in real time, when applied to a PC for analysis of records not in real time and pre-recorded. QRS complexes detection algorithm was published Dzhiapu Pan and J. Willis. Tompkinson in the journal IEEE Transactions on biomedical engineering, vol. BME-32, NO. 3 in March 1985. The algorithm has been designed for use in real time. Pan and Tompkinson developed an algorithm for real-time detection of QRS complexes of ECG signals. Algorithm for QRS complexes reliably recognize, by analyzing the inclination of the complex amplitude and width. Special digital bandpass filter reduces the number of false detections caused by different kinds of interference present in the ECG signal. This filtering allows the use of low detection thresholds, thereby increasing the sensitivity of detection. The algorithm automatically adjusts thresholds and parameters periodically to adapt to such changes ECG QRS morphology and as the heart rate. For standard recording duration 24 hours from the database MIT / BIH arrhythmia database, this algorithm correctly recognized 99.3 percent QRS complexes. However, this time the algorithm is rather outdated, as it was designed for computers that time. With certain modifications and current capabilities, parameters can improve the quality and speed of analysis. A modified version of the algorithm has been developed for use in the client software mobile multifunctional hardware-software complex and long-term cardiac monitoring ergonometrii. Better and more precise analysis of QRS complexes in the signal more accurately assess the state of the cardiovascular system of the person, which is an important factor in the treatment and diagnosis of heart disease in the early stages.

The issues of spatial orientation and navigation in the environment of large university complexes. The various functional and urban planning types of university complexes based on spatial orientation. The problems of spatial orientation in the built environment for the two types: urban "local" systems "integrated" type; Country (or suburban) campuses. Was investigated systematized modern "language" of visual communications for the university environment. Stand "information carriers" and "information structures" among university complexes "functional spatial structure" building "composite structure", "decorative plastic" and "semantic-graphic" structure. The conceptual model of the "frame of orientation" university environment as a complex system of spatial orientation of the inner and outer three-dimensional structure of the building. Marked methodological stages of the project forming a "frame of orientation" for new construction and modernization of university complexes. Stages based on three levels of visual contact "newcomers" and open objects and interior environment of the university complex "occurrence" on Wednesday, "awareness" of the environment, "dissolution" in the medium.

The article discusses the dependence of mechanical flexural strength porcelain stoneware on the content and type of phases composing his ceramic body. It was found that the high strength characteristics of products is achieved by increasing the amount of content of crystalline phases and glass phase. An increase in the number of metakaolinite consisting stoneware contrary, leads to a reduction in its strength.
