In recent years, the use of various tools based on machine learning in the process of writing the source code of various programs, interfaces, and websites has been gaining momentum. These include programs that help in testing applications, programs that analyze the developer's code, as well as assistant programs that help write code right in the process, predicting and prompting the developer with options for the finished program code. In this article, just the same, such assistant programs will be considered in order to analyze the shortcomings and justify the need to develop functionality in this direction.

The article examines the influence of observance of the frame dome-shaped roofs assembly technology on the quality of the completed object. This theme is relevant enough, as the building roofs, constructed in accordance with the aforementioned technology, are often found in modern business clusters. It`s natural that prospective investors are interested in perfect quality and seamless service properties of similar construction object designs. The authors considered features of the frame dome-shaped designs construction and assigned its pros and cons; the review of the technical investigation of one of the shopping centers was conducted with purpose of showing the consequences of inaccurate observance of the specified designs installation technology. Subject to facility technical investigation results, recommendations for the safety operation of dome support structures were given.

In this paper we present the method of detecting of low-rate DDoS-attacks on the http-services. A low-rate attack model in the form of a chronological series of events with an additive superposition of attack and normal traffic is used. The task of developing a method of detection of low-rate attacks is formulated as allocation of homogeneous groups (patterns) of the time series, based on pattern recognition models, and the subsequent construction of prediction model for each separate group.

The article discusses the possibilities of using forklift trucks (stacker-reach trucks) for mechanized installation of dividing walls, when cast-in-place slabs are assembled or manufactured. It is emphasized that in the early 1980s similar equipment that didn’t have a series production, was used in the construction of buildings by the lift-slab method. Some technical characteristics of the old equipment and modern warehouse equipment are compared, the advantages of the modern are revealed. It is noted that the simultaneous use of warehouse equipment on several floors of the erected frame building can lead to a significant reduction in the construction time. It is also indicated that the stacker-reach trucks used at the construction site are multifunctional, since they can not only transport construction cargo but also serve as an auxiliary equipment for safe work at a certain altitude when performing welding operations and fixing joints.

Measurement results of basic characteristics of electronic module based on two specialized analog integrated circuits depending on different square area silicon detectors using source of 239Pu alpha particles is given. Processing of current pulses typically consists to convert them into a voltage by charge sensitive amplifiers and reduce noise by bandpass filters. Earlier for work with avalanche photodiode we have developed, constructed and tested two electronic modules "CRP-MDL-1" and "CRP-MDL-2". During the measurements was investigated spectrometric channel response on exposure to ionizing radiation from a source of alpha particles 239Pu and test input signals, thus we determined basic technical characteristics including energy resolution and noise characteristics. As a result, research found, that the output signal has the following timings: rise time - 1 us (levels of 0.1-0.9), peak time - 1.4 us, fall time - 1.8 us pulse width - 3.5 us. The conversion factor of module working with silicon detector (area of ​​1000 mm2 and a capacity 500 pF) consists about 10.6 mV / fC, or 0.47 V / MeV. Integral nonlinearity of spectrometer path is not worse 0.4% in the range from about 0.1 to 3.2 V. The energy resolution was 89.1 keV line of 5157 keV. The experimental studies revealed that using an external low-noise transistors developed module can be used in the construction of standard radiometric paths. It is appropriate to use the developed design-circuit solutions for implementing 4-channel chip for multi-channel radiometric and spectrometric systems.

After accession of Russia into the WTO the tasks related to the development of infrastructure have been sharpen. With the growing volume of cargo traffic and the lack of opportunity for the extensive development of the port infrastructure, the alternative of building the dry port can be only feasible, although explicitly the most expensive. Due to this reason the method of gradual development of the dry port which provides significant economic efficiency was addressed in the article.
