The article describes the subsystem of workflow of the department at the institute “The calculation of teaching load”. As the process of calculation of teaching load is very complicated it has become necessary to make this process automatic. The mental card was developed where we can see the structure of the program for calculating teaching load. The subsystem has simple and understandable interface. The results of its work are represented in the form of filled blanks adopted by the academy in EXCEL. The created subsystem makes easier the teaching process of the department at the academy very much
When sowing grain we apply resource saving technologies-technologies such as «no till» and a technology called «mini-till». «No till» involves planting crops on untreated surfaces. "Mini-till" is designed for the planting with minimum tillage. During the movement of the sowing unit on these agricultural backgrounds we can see working bodies tipping out. Stabilization of the drilling depth is ensured in two ways - by moving part of the weight of the planter on the opener or the installation of ballast weights. Openers of grain drills for resource saving technologies for grain crops can be divided into three groups – foot, disc and anchor. Disc coulter has varieties – single disc, double disc and montesquiu coulter. To analyze the cost of power for the operation of the opener, the following indicators – the minimum engine power of the tractor on the coulter and engine power of tractors per unit of working width. The calculation of the indicators was conducted using data the technical specifications of the planter. Snow coulter drill AGRATOR4800 provides a wide spread planting strip of 10-15cm. The minimum power of the engine of the tractor on the opener is 7.5 HP minimum power of tractor engine per unit of working width 25 HP/m. Double disc opener planter Great Plains has a minimum engine power of the tractor on the opener 2.7 HP and per unit of working width 26.0-28.44 HP/m. Planter equipped with disc knife for strip tillage. The planter Condor 1201 is provided with a chisel opener «ConTeC». The engine power of the tractor on the opener of the planter is 4.58 HP, the engine power of the tractor unit working width constitute l8.33 HP/m. This grain seeder has reduced power losses and provides sowing with a «no till» technology
In the article we have proposed a program, an object, a methodology and results of field studies of the improved potato digger KTN-2V equipped with the original device for separation intensification
There were shown the main types of heat accumulators with different heat-accumulating material. There were considered the simpler and reliable equipment of het accumulation. There were set off the questions of heat accumulation and methods of intensification of the process of heat emission at the expense of use of flow turbulizator use
Protective forest plantations, shelter belts and plantings along the highways of Central - Black Earth region and southern Russia are badly damaged, and in some areas destroyed. Therefore, they can not perform their functions and require major reconstruction or restoration. The most resistant and applicable trees and shrubs to create protective forest plantings are: maple, ash, elm species and three-thorned acacia, honey-locust, white and yellow acacia, and other legumes breeds with high drought tolerance, disease resistance, technogenic pollution and pest damage. For the creation and restoration of protective forest plantations we require seeds of these species containing pericarp. In Voronezh State Forestry Academy we have carried out a scientific research for creation of a machine for extracting seeds from the legumes. Analysis of the results of scientific research of prototyping machines showed that they were made without considered technological and mechanical properties of the legumes theoretical researches workflow machines for extracting seeds from the legumes and scientific basis of design parameters and operating modes. In this article we have a presentation of the experimental sample of the machine for extracting seeds from the legumes and theoretical investigation of the workflow in the batch hopper. According to the results of the study, we have obtained a mathematical expression, which allows you to define the parameters and modes of operation of a brush-grater device
Currently, secondary resources of vegetable raw materials are widely used in solving the food, environmental and energy issues, as well as an additional source of substances of natural origin. A significant amount of secondary resources is produced during the processing of sunflower seeds - the main oilseed Kuban. Fats industry, while processing seeds, mainly extracts only one component - vegetable oil and is having a huge amount of meal, which is mainly used for agricultural purposes. Valuable property of sunflower meal is that it is high in protein, low cost and lack of toxic and anti-nutrients. Favorable amino acid composition determines the viability of recovering proteins from sunflower meal. Proteins were extracted from sunflower meal with a dispersing agent which may be water, sodium salts, alkalis, acids, or any organic solvent, followed by precipitation of the protein at the isoelectric point with hydrochloric acid. However, this protein has a high content of phenolic compounds, which gives it a dark color. The high concentration of chlorogenic acid in sunflower meal and its ability to form a dark colored complex with proteins limits the use of sunflower proteins in the food industry. All known methods of protein purification products from phenolic compounds, in particular chlorogenic acids, are mainly aimed at reducing the use of solvents and washing using membrane technology. However, in most cases, their use is either inadequate due to removal of phenolic compounds or decreasing the nutritional and biological value of the obtained product due to the toxicity of the solvent used, and an inability to completely remove it from the protein
The physical-mathematical model which adequately describes the work of tree planter main units has been developed. This model will allow to present all the technological process of the mechanized planting by means of the software and to carry out the analysis researches
The article proposes the implementation of neuro-fuzzy neural network topology of "Internal Teacher"
We have done the research of the possible connections in the real system of the process of choice the knowledge from the area of knowledge. It has been identified dependence the number of the straight con-nections in this system from the number of elements in the system. For this it was used an example to solve a particular scientific problem - the choosing the required method of optimization from the variety of optimization methods. In the real system of the process of choice the knowledge from the area of knowledge have been identified and researched various connections – the straight and reverse connections, the connection of generation and structural connections, the functioning connections. It became evident, as these connections are formed from the straight and reverse connections in the real system. For some connections were obtained quantitative relationships
