This article discusses image transfer in JPEG2000 format using JPWL antinoise coding via noisy channel with occurrence of packet errors. The main problem is recovery of received image with minimum deviations from input original. The aim of this work is to study experimentally the capability of JPWL protection to maintain quality of received and decoded image depending on the level of packet loss in data transmission channel. The experimental procedure consists of simulation of multiple transfer of JPWL protected image with the size of 1024×768 pixels and packet loss with the coded image data. Variable parameters of the study are: JPEG2000 coding procedure (irreversible conversion), Reed–Solomon codes used for JPWL protection, per cent of packet loss. Regular variant of JPWL protection is considered as well as combination of regular variant with algorithm of in-frame interleaving. The final experimental results are PSNR similarity extent of received and decoded image and input image, average per cent of completely recovered tiles with respect to tile number in code stream. The article describes the software complex developed for these studies, which includes JPEG2000 coder and decoder, JPWL coder and decoder, means of code stream dividing into RTP packets, simulating means of packet loss, assembling of frames from RTP packets. Operation flowcharts of JPEG2000 coder and decoder are described. It is mentioned that under conditions of packet errors JPEG2000 decoder should be able to process partially damaged or absent tiles. In-frame interleaving of code stream is described aimed at improvement of its stability with regard to packet errors. Three hypotheses are formulated. Hypothesis 1: in the case of packet loss the regular JPWL extension is unable to maintain quality of received and decoded image. Hypothesis 2: in the case of packet loss the regular JPWL extension in combination with algorithm of in-frame interleaving maintains the quality of received and decoded image. Hypothesis 3: in the case of packet loss and with application of algorithm of in-frame interleaving the PSNR value of received and decoded image depends statistically on the number of tiles completely recovered by JPWL decoder. As a result of the experimental study, all the hypotheses were fully confirmed.

The article deals with the issues of impact interaction of particles with layers of dispersed material of different thickness. The influence of the interaction velocity and the thickness of the substrate on the appearance and structure of the collision result is investigated. It is established that at low speeds there is a crater formation while the particle is on the substrate surface. With the growth of the interaction rate, the formation of a crown is observed, and particles penetrate into the substrate material. Experimentally determined the values of the velocity and thickness of the substrate, corresponding to the beginning of the formation of the crown.

the design of a new object presupposes not only the functional aspect, but an important factor is the location of the building or structure. The choice of location is one of the fundamental criteria: it is necessary to take into account the infrastructure and architectural appearance of the selected area, the needs of the district or region in the projected facility.

Discusses actual problems of determination of the resistance and protection of concrete structures – slabs, produced by standart adopted in the Russian Federation and the United States. Studied national and international experience of evaluation and quality control, measures to preserve the integrity and stability of structures to various types of exposure. The focus is on those conclusions that must be made from the analysis of the causes of destruction in order to avoid future repetition of mistakes and miscalculations that are allowed currently in the design and construction of engineering structures and which often lead to the occurrence of accidents.

The aim of this work is to study the degree of protection of underground waters of the Kuibyshev district of Rostov region. The study area represented by the geological deposits of Quaternary (recent sediments) Qh, Neogene and Paleogene systems (Oligocene) P3, Cretaceous (upper division) K2 and the Carboniferous system (upper, middle and lower portions) S1,2,3 based. On the analysis of geological structure of water-bearing rocks in the Kuibyshev district of the Rostov region, which showed an insufficient degree of protection of underground waters against pollution and, as a consequence, insufficient supply of public drinking water, built map of underground waters protection of the Kuibyshev district of the Rostov region

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.

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.

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.
