  • Questions of dynamics of destruction of streams when forming drop ablation in processes of putting electroplated coatings

    In article dynamics questions formation of drop ablation at destruction of bubbling streams are considered at a rupture of bubbles, experimental data of some characteristics of processes of destruction of streams are given, the analysis of the factors influencing formation of drop ablation is made

    Keywords: drop ablation, bubbling, drop, stream, blanket

  • Prospects for the development of remote methods of the quality control of construction products by measurement

    The article presents the results of the analysis of the known methods of measuring the quality control of construction products. 
    Advantages of extending the scope of remote methods of the control by measurement including photogrammetry are listed. 
    Expediency of colour-texture analysis of surfaces at the quality control of construction products is substantiated.
    The field of rational application of colour-texture analysis at manufacturing supervision and field inspection of buildings and constructions is shown.  

    Keywords: building structures, product quality inspection, control by measurement, organoleptic inspection, methods of photogrammetry, colour texture analysis

  • Possibilities of nonmetric digital cameras in ground-based photogrammetry

    One of the main advantages of digital imaging - the ability to create highly informative models of studied objects and terrain , which is achieved by the use of vector graphics primitives , as in the image plane and in the space of the stereo . Digital photogrammetry is available for many sectors of the economy , as does not require expensive equipment. However, the accuracy of the decided tasks affects the fact that the digital photographs have lower depictive properties and informativeness, with their comparison with the photographs, furthermore for their working large computational power be required.  Under the contemporary conditions ground-based stereophotogrammetrical survey, with the smaller cost of operation, allows rapidly, and also in the regime “real time”, to obtain the large volumes of information about the object being studied .

    Keywords: Photogrammetry, digital image, digital cameras, ground-based stereophotogrammetrical survey, the calibration

  • Digital proton magnetometer to measure the geomagnetic field

    Digital compact proton magnetometer was created for measure the geomagnetic fields, including the fields of high heterogeneity. We described design of the instrument and its principles of operation. This device is using implemented digital filtering techniques and Prony method to determine the frequency of the desired signal. The experiments were made in the fields of high heterogeneity and demonstrated the possibility of precise measurements in the fields with a gradient of up to 8 mT / m. The device can be used as a metal detector, as well as for magnetic prospecting, geological studies, etc.

    Keywords: nuclear magnetic resonance, free precession, proton magnetometer, geomagnetic field, digital filtering, Prony method
