The settlement scheme of the four-link robot moving with a jump from a surface is provided, the jump of the device is described in the form of sequence of stages, on each of which links of the robot make certain types of movement, the mathematical model in the form of the differential equations describing movement of the robot at all stages is developed, results of numerical modeling of a jump according to the specified sequence of stages are presented
The article considers the stages of the passage of the
project in the organization. Decision support system
facilitates the work of heads of enterprises and
enhance its effectiveness. The organization has a
system of registration applications, which contains the
information about the project, its description, the terms
of development, the developer (or development team)
and stages of this project. Using the software package,
the customer leaves the application to provide services.
Head sends a request to the appropriate division.
Departments, in turn, transmit information about the
status of implementation of the application through a
software package. The software package enables fast
two-way remote communication in electronic form
between the customer and the head, and between the
director and divisions. The organization coordinating
the work on the implementation of IT-projects by the
head and the head of the sector. But there are some
human factors, through which people can not keep up
with the timely implementation of all tasks given by
subordinates. Developed DSS helps to save time in
monitoring the project development phase, will
eliminate the human factor in monitoring the success
of the project, and will assist in the decision-making in
cases of force majeure. Development of an IT project
consists of several stages, each of which has the ability
to give interest characteristic of the total time spent on
the project. Supervisor carries out the decomposition
of the problem and evaluation of each stage
The article describes a circular two-surface threecomponent
jet agitator (pump). The calculation method of critical precavitation speeds and in-flows of livestock wastes and mineral fertilizes was introduced
The article discusses a promising direction, aimed at improving the operational and technical characteristics of the autonomous power supply systems, through the use of a part of their gas piston power plants, wind pow-er and solar photovoltaic installations
The article provides comparative analysis of three laws
in the area of standardization in different phases of its
existence and development of our State: “About
Standardization” 10.06.93 № 5154-1, “About
Technical Regulation” № 184-ФЗ (part III) and
«About Standardization in Russian Federation”
№ 162-ФЗ. It is noted that standards and other
documents addressing standardization facilitate
technical development, innovation in different spheres,
quality improvement and competitiveness of industry,
products and services. The authors of the article trace
close interconnection between the state of the laws and
the concepts of Russia’s development, change of
goals, tasks and principles of standardization in
relation to the changes in the country and in the world;
analyze the experience of Russian standardization and
evaluates innovations in the modern jurisprudence in
this area. The authors of the article evaluate the laws in
the area of standardization from the viewpoint of its
importance and transparency for consumers based on
its close correlation with the law “About Consumer
Protection”. Additionally, they note the importance of
these documents and standardization in general to the
development of the country’s economy, its integration
into the world sphere and achievement of
technological leadership of the Russian Federation in
different areas

The requirements for the interaction with VoIP telephony are proposed and the features of SIP, RTP, UDP protocols are described. The article describes the current capabilities of data streaming through a web browser using different approaches: the browser add-on, Adobe Flash technology and WebRTC protocol . In conclusion, the comparison of the existing solutions for data streaming through a web-browser to VoIP telephony is presented
The article explains the importance of the transport process when performing repair jobs of asphalt roads. The scheme of the technological process was drawn up; job steps were identified, while the latter may be characterized by non-productive downtime of transport as well as that one of technological machines. We have analyzed the following steps of the flowchart of the road concrete mix transportation: the preparation of the road concrete mix for transportation, loading, transportation, unloading, laying and packing. The transportation of goods starts at the working site of their production and ends at the site of their consumption. The transportation process is a multistep and multioperational process having the greater diversity of technological, operational and economic operations, which must be correctly organized. It is extremely important to deliver the road concrete mix of coating plant (OP) just in time, while avoiding the unproductive idle standing of the equipment, the deterioration of the mixture, as well as performing the job steps at minimum transportation cost savings. The successful combining of the steps of the concept organization of the road concrete mix transportation (coating plant, asphalt laying step, transportation step) will improve the performance and will provide the reduction of the job cost. One must perform the coordination of job steps on different road sections using information technologies and communication facility
