  • "Construction of translucent roofs. Part 2. Innovative technologies and materials "

    This paper logically continues the first part of the work describing roof construction with the use of translucent materials. The analysis of the current tendencies in the construction of roofs for sports and entertainment facilities showed that the contemporary studies are focused on the development of sliding roofs and the most recent trends feature façade and roof coatings made of ethylene copolymer and tetrafluorethylene based (ETFE) film. This paper discusses the most prominent advantages of membrane cushion roofing in the light of the summary analysis covering the articles of foreign authors. It mentions that ETFE cushion roofs are also used to restore buildings and structures of historical significance. The paper goes on to suggest a new structure of sliding roof and describes the construction technology taking into account the experience of building ETFE cushion roofs.

  • Influence of route vehicle traffic volume on the road network capacity

    This article considers influence of route vehicle traffic volume on the road network capacity. The atrcile introduces the change of passanger traffic according to hours of the day on the bus routs, which are laid through signaled crossings of streets Kyubisheva - 8 Marta in Yekaterinburg nearby big transfer transport junction in the distric of subway station ""Geologicheskaya"". Recieved data gives an opportunity to identify percentage of buses in the transport stream. It is one of the factors that influences on the calculations of the length of traffic signal cycle. The analysis of received statistical data lets us draw the following conclusion: 1. To reconstract network of streets and provide the maximal traffic capacity on the crossings, it is necessary to consider variable structure of transport flow. 2. To calculate the length of traffic signal cycle it is necessary to consider the bus traffic volume, which changes according to the time. 3.There was determined the change dependency of passanger traffic on hours of the day on the bus routs. It gives the possibility to predict changes in the length of traffic signal cycle. 4. Recieved results can be used to calculate the length of traffic signal cycle and in order to developn an optimized route network of passenger transport.

  • Research and development of methods for creating model for combinational circuit implementation in FPGA basis

    The paper presents a method for creating model for combinational circuit implementation in FPGA basis, through its original description. This model represents the equivalent circuit of the FPGA logic elements. The scheme can be used for the calculation of various parameters such as speed, area, power consumption etc. The paper proposes to use this model to assess reliability in relation to the single fault in combinational circuit’s parts or the configuration registers. Furthermore, the resulting equivalent circuit can be modified and re-synthesized in the CAD environment to achieve high levels of resistance to a single event upset. Direct estimation of the masking properties of the logic circuit through its original description is impossible because of substantial change in the structure due to the synthesis process. Evaluation of fault tolerance after place and route is not available due to lack of the necessary tools in modern CAD (Altera Quartus II, Xilinx ISE, Synopsys Synplify). To evaluate the reliability of the project one must create custom FPGA netlist analysis tool and tools for modeling combinational circuits.

    Keywords: reliability evaluation, re-synthesis, combinational circuits, FPGA, fault injection.

  • Experimental investigation on the quality of holes in the multi-layered GFRP-titanium obtained in drilling operations

    The purpose of this work was to study the influence of the structural and geometric parameters of the twist drill on the quality of the processed hole and productivity of machining the high strength polymeric composite material – glass fiber epoxy-based plastics that are reinforced by titanium foil. In the structure of high loaded polymeric composite parts the reinforcing layers made from the titanium foil are used. These titanium layers are placed between layers of the winding unidirectional glass fiber tape or the carbon fiber tape. In order to reach the required dimensional accuracy, the macro- and micro geometry of the hole surfaces, to eliminate the overheat, burning, and delaminations of material, need to use sharp-edged tools, which wear out quickly, and remove the drill from the workpiece at frequent intervals to clean the chips from the flutes of the drill and the hole being drilled. We studied the drilling of glass fiber reinforced laminates at the different schemes of sharpening the drills made from the high-speed steel. We present some experimental results of the optimal feed and speed for the studied twist drills, the dependencies of the highness parameters of roughness, and also characters and degree of delamination at starting and finishing hole for the different tools, feed and cutting speed.
