• DOMINANT TECHNOLOGIES IN “INDUSTRY 4.0”

    USE OF DRONE BASED IT SYSTEM FOR ROAD POTHOLE DETECTION AND VOLUME CALCULATION

    Industry 4.0, Vol. 4 (2019), Issue 5, pg(s) 223-227

    This paper will examine whether information technology solutions can contribute to the work of a road repairer. The aim of the research is to develop an algorithm for identification and volume calculation of the road pits.
    The paper presents an overview of three existing methods to identify holes as objects. Recent study uses an ultrasonic sensor to determine the size of a 3D hole; special attention is paid to its noise classification and possibilities for its reduction. The authors have found a way to organize road surface scanning, convert the resulting data into binary code and calculate the volume of the object. Calculations can be made on both a mobile microcontroller-controlled device and a computer after receiving data. A worker, a self-propelled robot or a drone can be used as a sensor carrier.
    Study results can be used for further development in the field of transport systems engineering, as well as for mechatronics specialists to develop algorithm realization equipment in a real environment.

  • COMPUTER-AIDED MECHATRONIC DEVICES: AESTHETIC DESIGN WITH AN EMPHASIS ON GENERALIZED GOLDEN RATIO

    Industry 4.0, Vol. 4 (2019), Issue 1, pg(s) 15-18

    Research is devoted to contemporary computer-aided mechatronic devices (like indoor mini-gardens, non-living devices) construction / design issues. Particular emphasis has been put on mechatronic devices` aesthetic design arguing its practical value. Design related discussion as been focused on Golden Ratio archetype in particular (more – Generalized Golden Ratio)

  • NUMERICAL MODELLING OF FLOWS ALONG THE NANOSTRUCTURED SURFACE

    Materials Science. Non-Equilibrium Phase Transformations., Vol. 4 (2018), Issue 4, pg(s) 129-132

    Not all the properties of structured surfaces can be predicted just through using stationary solutions. Hydrophilic and hydrophobic qualities distinctly manifest themselves when surface contacts with mobile liquid; besides, shape of surface projections could variously influence flow velocity in different directions forming turbulences behind projections (even cavitation zones if flow is very fast). The following properties of liquids are particularly important for these processes: dynamic and kinematic viscosity, density, flow velocity and characteristic flow size, which represents itself contact surface relation to cross-sectional area. Relationships between these parameters characterize flowability of the particular substance and can be expressed as Reynolds number. Solutions of kinetic equations could be helpful to develop understanding on particular fluid’s flowability in the close vicinity of the surface.
    Examples discussed in this paper can be used not only in nano- and microstructures related research but also for high school and university students training in physics and natural sciences. Comprehension development about flow rate diferences in various distances from tube walls should be considered as one of problems for successful acquiring of hydrodynamics topics. Even use of transparent tubes is not helpful enough for appropriate demonstration of tinted liquid speed distribution in flow’s cross-sectional area – laminar flow when Reynolds number value is low and turbulent flow when it is high.
