The ways of improving the work of food enterprises during processing of agricultural raw materials on the basis of a system analysis of the durations of technological operations are considered. The basic mathematical models of technological processes have been analyzed and the possibility of using unified technological operations to predict the time of completion of work has been shown for processing various pairs of raw materials. It is established that the construction of mathematical models of technological processes of processing of agricultural raw materials should be based on using the potential of transfer of the target component between isopotential surfaces. This allows not only to unify the created models of technological processes, but also to significantly increase their extrapolating ability to estimate the durations of technological operations

To reduce the development of additional settlement
strip foundations of the existing building on the effect
of pressure transmitted to a ground base located near
the new slab foundation is considered the work of the
geotechnical barrier in various ground conditions. In
the first variant of soil, conditions (variant 1) made
geotechnical barrier structure in a homogeneous
thickness of the weak clay soil. In the second variant
of soil conditions (variant 2), a separating barrier is
performed in a two-layer base. The upper base layer
(carrying) is shown a weak water-saturated clay soil,
and the second (underlying) - low compressible soil
(sandy loam plastic). According to the results of the
calculations and modeling found that, the greatest
positive effect on the separating barrier structure
(geotechnical barrier) is achieved in the case when the
base is a two-layer. The lower part of the geotechnical
barrier must be recessed into the soil of low
compressibility. Additional settlement strip foundation
of the existing building in a uniform basis (variant 1)
in the absence of geotechnical barrier is approximately
8 cm. In the case of a two-layer base (variant 2), the
additional settlement strip foundation building is
reduced by 80-85% (6.6 cm) and will make about 1.4
cm

There are three main growth points of modern information technologies: global network and mobile communication, advanced human-machine interfaces, intelligent technologies. As it is known, the system (synergistic) effect is usually observed in multidisciplinary and interdisciplinary researches. This means that an interesting direction of research and development is located at the overlap of these three promising areas, namely: advanced interfaces in the global mobile networks, advanced intelligent interfaces and the application of artificial intelligence technologies in the Internet and mobile communications. In addition, a particularly high relevance goes to the development and application prospective of intelligent interfaces to the Internet and mobile communications. The Internet intellectualities gradually, it turns from non-local storage of large data (big data) in information space that contains meaningful big data, i.e. "great information" (great info), and then in the space of knowledge or "cognitive space" in which most information is actively used to achieve goals (management) and turns into the "great knowledge" (great knowledge). There are more sites devoted to artificial intelligence, free databases for machine learning (UCI, Kaggle, and others) and even on-line intelligent applications, and interfaces used in the Internet are improving. Recently, there was an acquisition of company Oculus, which is the world's leading developer and manufacturer of ammunition of virtual reality by the developer of one of the first global social networking Facebook - Mark Zuckerberg. However, students and scientists still do not notice that open, scalable, interactive, intelligent on-line environment for learning and researches already exists and operates, based on automated system-cognitive analysis (ASC-analysis) and its programmatic Toolkit – intellectual "Eidos" and the author's website. This article is an original presentation and it is designed to familiarize potential users with the capabilities of this environment

The object of study is a car service enterprise. This article provides approximate content of the main sections of the documentation on organization of industrial environmental control and provides recommendations on creation of environmental car service enterprises. The approach for organization of production environmental control and offered samples of the documentation can be widely used in various industries
Numerous studies confirming the effectiveness of the
use of the ozone-air mixture in various fields of
agricultural production lead to an increase in demand
for devices that generate ozone. With the increase in
demand, the requirements for these devices also
increase. Requirements from customers can be
combined in the following series: mobility, ease of
operation, ability to smoothly control performance.
The solution of these tasks is an important scientific
and technical task. This article describes possible
options for power supplies for ozone generators, and
offers a power supply circuit with the ability to adjust
the frequency, the duty cycle and the amplitude of the
signal arriving at the discharge gap of the ozonizer.
Using this scheme will reduce the mass-size
indicators of the ozonizer, thereby increasing its
mobility, in addition, it will be possible to accurately
regulate its performance and improve efficiency. If
necessary, with the help of the proposed scheme, it is
possible to introduce the ozone generator into the
electric resonance mode, which will allow obtaining
the maximum productivity of the ozonator. Thus, the
ozonizer, equipped with the proposed power scheme,
can be used in various technological processes of the
same enterprise
The article considers the model of granulometric
composition of foundry dust. We used the method of
