In this article the basic principles of air-fuel mixture explosions and striking factors, such as air-striking wave, gas streams, splinters, flame heat, light radiation and sharp sounds are observed. The calculation technique of the emergency emission consequences which is for a quantitative estimation of air-striking wave parameters at air-fuel mixture explosions forming in the atmosphere at industrial failures is given. The basic structural elements of calculation algorithm are listed. It is supposed partial depressurization or full destruction of the equipment containing combustible substance in a gaseous or liquid phase, the emission of this substance in the atmosphere, the air-fuel mixture cloud formation, the air-fuel mixture initiation (ignition) and the explosive transformation (deflagration or detonation) in the air-fuel mixture cloud. The technique allows making the approached estimation of air-striking wave various parameters and defining the probable degrees of men defeat and building damage at failures with air-fuel mixture cloud explosions. The given technique is developed in C# language in the integrated environment of software Microsoft VisualStudio 2010 working out. The program fragment in which the calculation of dimensionless Px pressure and dimensionless Ix impulse is given
During an era of rapid development of society and all
areas of its activity, special attention should be paid to
a condition of the objects considerably simplifying
humans’ life. The car, which began to be an integral
part of each family, is among such objects. But
sometimes, the car can get into accident and then some
malfunctions appear. For their elimination, motorists
address to the specialized organizations for car repairs.
The article is devoted to introduction of information
technologies to the sphere of rescue and recovery
operations of a body of the car. Today, a necessary
condition of advance in the sphere of information
technologies is widespread introduction of standards
and technologies of the information systems used both
for hardware, and for software products. In this study,
the efficiency of application of the complex of
hardware (CH) by means of which achievement of
improvement of quality of rescue and recovery
operations, through a possibility of comparison of the
damaged detail with its factory model and a possibility
of quality check of the end result will be considered.
The set of methods and techniques of the organization
of information processes in the production systems
allowing carrying out the choice and use of necessary
information technical solution for synthesis of
knowledge of a production situation makes contents of
the concept of formation of information resource of a
control system of the knowledge-intensive production
Introduction of mineral fertilizers is performed by centrifugal devices. By quantity of disks, centrifugal devices distinguish one disk and two-disk. On the volume of capacities for storage of mineral fertilizers distinguish bunker and body. Bunker contains volume from 0.5 to 1.5m3. Body has capacity more 2m3. Advantages of bunker centrifugal devices are noted. Material from the bunker moves on a centrifugal disk perpendicular to the rotation plane. At the time of material capture by shovels, crushing of particles and their reflection from shovels and the plane of a disk takes place. It leads to increase in unevenness of introduction of mineral fertilizers. At EMTP chair of the Kuban GAU the centrifugal device with supply of material along shovels is developed. The scheme of the centrifugal device is submitted. A device for introduction of mineral fertilizers contains the one-disk centrifugal device, the cone-shaped bunker and the cylindrical batcher. The batcher gate regulates supply of material on a disk. The technique of determination of design and technological data of the developed design is presented. The place of supply of material on a disk is regulated by rotation of the batcher round a vertical axis. The norm of supply of material on a disk changes the batcher gate. Preliminary control of a place of giving is made on model material with coefficient of friction of f 1. Under production conditions, turn of the batcher from initial situation is made depending on coefficient of friction of the f2 fertilizers.
At f1 ˃ f2 turn of the batcher against the direction of rotation of a disk, and at f1 ≤ f2 turn of the batcher in the direction of rotation of a disk
In the article the current version and some prospects of development of Universal cognitive analytical Eidos system - one of the oldest really working domestic universal systems of an artificial intellect widely applied and developing nowadays is shortly described
In the article we present a possibility of creation of the 2-speed synchronous and asynchronous electric motor and scientific bases for its design
The article proposes to use the automated systemcognitive
analysis (ASC-analysis) and its software tool
which is "Eidos" system to solving multiparameter
typing, system identification and cartographic visualization
of spatially-distributed natural, environmental
and socio-economic systems. Imagine, that we have an
original point cloud with coordinates (X,Y,Z), each
with known values of gradation descriptive scales of
nominal, ordinal, or numeric type S(s1,s2,...,sn). Then
the "Eidos" system provides: 1) building a model that
contains generalized knowledge about the strength and
the direction of the influence of descriptive gradations
of scales at Z=M(S); 2) estimation of the values of Z
for points (X,Y) described in the same descriptive
scales S(s1,s2,...,sn), but not a part of the original point
cloud; 3) a cartographic visualization of the spatial
distribution of values of the function Z=M(S) for
points outside the initial cloud, using Delaunay triangulation.
Basically, this means that the "Eidos" system
ensures recovery of the unknown function values on
the grounds of the argument and implements it in a
generic setting, independent of subject area. We propose
a new scientific concept called "Geo-cognition
system", which is defined as a software system that
provides conversion of source data into information,
and knowledge in visualization and mapping of this
knowledge, resulting in the cognitive map becomes
graphics. This feature can be used to quantify the degree
of suitability of the watersheds for cultivation of
certain crops, the evaluation of the ecological situation
on particular territories on the structure and intensity
of anthropogenic load, visualization of results of forecasting
of earthquakes and other unwanted risks or
emergencies, as well as for solving many other similar
mathematical essence of tasks in a variety of subject
areas. We have also shown a simple numerical example
