The article describes a software complex which allows carrying out computer experiments in the study of economic efficiency of integrated production structures in agriculture and their stream of interaction. The article provides software used in complex mathematical ratios and their machine algorithms implementation. The authors have given a detailed description of the user interface with graphic examples. The application is written in programming language C#. This language was chosen for several reasons. The first reason is of course that C# is cross-platform that gives you the opportunity to use this app on any platform, and plays an important role in research activities. The final decision was influenced by the fact that in C# is implemented for working with charts, using standard library chart that provides a significant advantage compared to other programming languages during the development of the software complex
This article aims to study the prospects of energy complexes on the basis of renewable energy sources to supply electricity to the stand-alone consumers in different regions of Myanmar. In order to do that territory of Myanmar is divided into some regions according to their amount of renewable energy sources, methods for determining the optimum parameters and operation of energy complex on the basis of renewable energy sources are developed and the cost-effectiveness of those energy complexes in the regional power sector of Myanmar is analyzed
In the article we present questions of digital process control of heated air for drying seeds; it is shown that the change in the load of the heat source slightly changes the dynamics of the system for stabilizing the temperature of hot air, making it almost invariant with respect to perturbations. It is proved that the use of digital controller with dual differentiation significantly improves the performance of the automatic control system, excluding the increase astatism of the management system
In the article the presented questions of theoretical research of processes of an electric resonance of the generator of ozone were discussed and their influence on productivity and electro-ozonizer efficiency was also defined
Tracking is a vast field of research associated with
navigation, robotics, and virtual environments (virtual
reality). Tracking for augmented reality requires higher
level of precision, increased range of action, as well as
work with a wider variety of input data. It is important
that augmented reality technology requires tracking in
real time, which also complicates the task. Correct
visualization of objects in three-dimensional space
requires six degrees of freedom tracking: three position
values (x, y, z) and three angles (rotation around the
respective axes) to determine the orientation. To solve
this problem, different approaches and sensor types are
being used. In this article, we present a brief history of
the development of tracking technology and analyze the
current approaches to implement the process of tracking
on mass mobile devices such as smartphones and tablet
computers. We also describe some issues in
implementing optical marker based tracking for
visualization of large scale models
Lecithin and sorbitol tristearate (Radiamuls Sorb
2345K) are the emulsifiers used in the manufacture of
chocolate products. The effects of various blends of
lecithin and Radiamuls Sorb 2345K when added in
concentrations up to 14 g / kg on the rheological
properties of molten dark and milk chocolate were
determined by rotational rheometry. The results show
that regardless of the total amount of emulsifier, yield
strength, both dark and milk chocolate most effectively
reduced by applying a mixture of approximately 30%
lecithin and 70% RADIAMULS SORB 2345K.
Regardless of the concentration of the emulsifier
proportion RADIAMULS SORB 2345K in the mixture
can be reduced to 25% without a significant increase in
equilibrium viscosity milk chocolate. With respect to
the total emulsifier dosage in the range of 4 to 6 g / kg,
the lowest values were found for the viscosity of the
mixture letsitin- Radiamuls Sorb 2345K 50:50 for dark
chocolate and milk chocolate to 75-25, respectively.
when using the mixture of lecithin-SORB
RADIAMULS 2345K there are various possibilities
for adjusting the rheological properties of chocolate,
confectionery coatings and fillers on fat basis. The
results obtained show that the confectionery mass flow
can easily be adapted to the specific processing needs,
thereby improving product quality and production
efficiency increases
The problem of identifying of the most promising polymer materials for sledge sliding application. The comparison of materials is given: the bench tests of polyethylene, fluoroplast, steel and ultra high molecular weight polyethylene (UHMWPE) with different molecular weight and their composites are carried out. On the basis of research of polymeric samples on ice and snow friction in exploiting condition with the use of specially designed sledges was shown that GUR 4150 UHMWPE has the lowest mass volume and linear wear. Also in article the results of research of ice adhesion to different materials are presented. Adhesion research was carried out in low temperature conditions of air from -21oC up to -46oC and in cryocamera according method which was patented by Institute of oil and gas problems of SB RAS. The research showed that GUR 4150 UHMWPE has the lowest adhesion to ice. On the basis of obtained data the authors assumed that GUR 4150 is the most perspective materials for development of sledge sliding exploiting in Arctic conditions.
The article is devoted to the solution of actual problems of protection of the population from noise production facilities. It shows the various fundamental technological approaches to the implementation of noise protection measures. This work conducts a comparative assessment of technical solutions aimed at reducing the levels of radiated noise, providing increased noise impact on the territory, from the gas distribution station (GDS). Production facilities everywhere are equipped with noisy equipment. If the noise level from the object in a residential area exceeds the permissible levels (RC), they sound events. The most common design decisions noise protection for today are: sound design; noise screens and barriers; insulating housings; sound cab. The article discusses the insulating properties of different coatings, composition and device of acoustic screens. It describes the course of the design work noise-reducing measures aimed at reducing noise levels in a residential area adjacent to the territory of one of the gas distribution stations (GDS). The description of the algorithm calculations, selection of materials for the implementation of activities, the combination of technical solutions that have practical novelty. The article is an exploratory in nature. At each stage of the embodiment of the design decisions were changes in the level of noise and the sound spectrum in the frequency range of 31.5 to 8000 Hz, evaluation of the effectiveness of the protective measures and the analysis of the influence of acoustic impact on the population. The results were presented for the year of research. The results of the research indicated graphically demonstrate the advantages of the proposed solutions for reducing noise levels in a residential area
