  • Study of SiO2SnOxCuOy Sensor Response Stability to Carbon Oxide (II)

      Stability of sensors on the basis of inorganic oxide materials is one of the primary goals by working out of atmospheric air control devices. In this work long-term stability of a sensor response on the basis of the SiO2SnOxCuOy material to carbon oxide (II) exposure in a range of concentration 1-100 ppm is studied. It is shown that the sensor response differs high stability and reproducibility. Continuous heating within 21 days to working temperature (350°С) influence its value negligibly.

    Keywords: stability of a response, sensor, carbon oxide, material of structure of SiO2SnOxCuOy.

  • Investigation properties of composite material for high sensitivity nitrogen dioxide sensors

      We have investigated electrical and gas sensitive properties of gas sensor based on carbon nanotubes (CNT) and carbon nanotubes modified by metal oxides (such as tin oxide and silicon oxide).  Also we  have find out that modification of  CNT by  metal oxides helps to  improve film`s adhesion to substrate, decrease electrical resistance, recovery time, working temperature , enhance gas sensitivity in comparison with sensitive elements based  only on CNT or metal oxides. Moreover experimental results showed that properties of composite material depend on concentration correlation of solutions. As a result we can get highest sensitivity of sensor element by choosing optimal relation between concentrations of solutions.

    Keywords: Сarbon nanotubes, modification, tin oxide, silicon oxide, gas sensor

  • Study the effect of different gases and volatile liquids on the mechanical properties of the films mycelium

      The algorithm of the research, including the technology of making the mycelium film on the resonator of bulk acoustic wave and gas medium with the given concentration was developed. As a result of the investigations the sorption sensitivity of extracts of the higher shiitake mushroom mycelium to the fume of volatile liquids and gases (acetone, ethyl acetate, formaldehyde, chloroform, acetic acid and hydrochloric acid, hexane, 10% aqueous ammonia) was studied. The study has shown that there are the processes of making the mycelium films, which keep the initial values of the resonant frequency and the quality factor of the resonator after moving off the fumes or gases. This work has shown that the mycelia films are very promising as a new material for gas selective coatings of electro acoustic sensors.

  • Formation of a geographical information database of residential and business housing stock of Rostov-on-Don

    Development of urban areas, especially Rostov-on-Don, which is one the largest city of the south of Russia, should be based on a comprehensive assessment and analysis of the structure of housing stock and engineering services, which provide all types of resources for the city. Research of the structure of housing stock, analysis of residential and private housings, municipal and business buildings, information on the territorial distribution of these objects with reference to the topography would allow to create a reliable information base for the development of district heating schemes. Housing stock of Rostov-on-Don was ranked by the year of construction, number of floors and material of the wall. The article assesses the providing of municipal and business buildings, kindergartens, schools, institutions consumer services, culture and sport institutions.

    Keywords: urban development, energy, heating, year of construction, material of walls, floors

    In work the scheme of regulation of a dynamic level of a liquid which can be used in systems of oil extracting with the purpose of increase of efficiency of their work is offered. The scheme of a regulator of the level consisting of proportional and integrated discrete elements that has allowed to reduce a static mistake is described and on the basis of to raise efficiency of regulation of a dynamic level. Modelling process of work of the offered scheme of regulation is lead, results are analysed and recommendations on parameters of a regulator are developed. Procedure of use of the offered scheme also for the control of a degree not fillings the pump is described.

    Keywords: The scheme of regulation of a dynamic level of a liquid, is proportional-integrated regulator of a level, regulation of a dynamic level of a liquid in a chink, not filling the pump.

  • Modern technologies of the superstructure of mansard floors in the reconstruction of residential buildings of the first mass series

    Is considered the superstructure of attic floors, as the most simple and effective техническиое decision in the reconstruction of buildings of massive series . Considered two variants of the device attics for residential buildings of the first mass series. The superstructure of mansard floors this is a very difficult technical, economic and social problem, and requires a scientific substantiation and consideration of a complex of organizational and technological issues of reconstruction, a detailed examination of each building, thorough comparative analysis of alternative variants of engineering solutions. In each case it is necessary to take into account the totality of the various factors and first of all the social aspects of reconstruction

  • Linear classification of objects using normal hyperplanes

      Is devoted to the actual problem of constructing classifiers objects given by a point in a multidimensional space of feature values. A version of the geometric separation of sets by hyperplanes normal to the center-distance data sets. This approach to separating planes reduces the computational operations performed. This author separability criterion allows a normal quite effective in terms of computational complexity the exact solution of the normal separation, which requires only a linear search of points separated sets. Proposed in the article the approach to classification of sets in the multidimensional space of values ​​of their attributes can be used as a starting point for building effective in terms of computational complexity classification not only for normally separable sets, but also for more complex variations thereof. This is the most significant practical importance of materials submitted by the authors.
