The basis of Semantic Web technology is the
possibility of joint construction of ontology and the
formation of the dictionary without centralized control.
All the information and the knowledge encoded in the
ontology as semantic web-terms and the semantic
web-documents. Swoogle helps software agents and
knowledge engineers find Semantic Web knowledge
encoded in RDF and OWL documents on the Web.
Navigating such a Semantic Web on the Web is
difficult due to the paucity of explicit hyperlinks
beyond the namespaces in URIrefs and the few interdocument
links like rdfs:seeAlso and owl:imports. In
order to solve this issue, this paper proposes a novel
Semantic Web navigation model providing additional
navigation paths through Swoogle’s search services
such as the Ontology Dictionary. Using this model, we
have developed algorithms for ranking of Semantic
Web objects at three levels of granularity: documents,
terms and RDF graphs. The article focuses on the
ranking at the document level, based on a rational
search model, which emits the agent's behavior when
navigating at the document level, and ranking on level
terms, the value of which is determined by the number
of their references in all documents
Fruit shell - a waste of food and technical products. Only in rare cases they are used adequately to their rich chemical composition. Number of pectin substances in the structural components of the cell walls of fruit shells rather high. We investigated the quantity and quality of fruit shells contained soy pectin. The result of these studies was the proposed method for producing pectin extract from this kind of raw material. It describes how to work on the creation of a method for producing pectin extract from the leaf of soybeans. It's possible to extract pectin from the raw material, not previously used and pectin extract standard quality by applying advanced parameters of the process of conducting the hydrolysis-extraction. Valves soybeans washed with cold drinking water, dried and then pulverized. Then the purification is carried out by impurities. After that hydrolysis-extraction is carried out with a solution of succinic acid with heating. Separation of the liquid phase is carried out after completion of the hydrolease-extraction. We have developed and implemented as described above, the method solves the problem of soybean seed production waste
Occupation of the Soviet territory by German fascist
invaders during the Great Patriotic War caused
considerable damage. The Soviet Government
developed legal and regulatory framework for the
methods of assessment of damage. The purpose of this
article is to analyze the legal framework, by the
example of a regulatory act according to which
calculation of damage to the collective farms in the
occupied territories during World War II was made.
The NKVD instruction "On the procedure of
collecting, recording and storage of documentary
materials relating to the atrocities, destruction, looting
and violence of the German authorities in the
occupied Soviet areas" was adopted in May 1942.
Based on the instruction, and under orders of the
NKVD in Elista, events to identify and collect
materials that characterize the crimes of Hitler's
government were carried out. According to these
instructions, materials reflecting Nazi atrocities were
subjected to the mandatory deposit of the State
Archives. The paper gives summary quantitative data
on the results of assessment of damage caused during
the occupation period in August 8, 1942 to January
20, 1943
Classic quantitative measure of the reliability of the models: F-measure by van Rijsbergen is based on counting the total number of correctly and incorrectly classified and not classified objects in the training sample. In multiclass classification systems, the facility can simultaneously apply to multiple classes. Accordingly, when the synthesis of the model description is used for formation of generalized images of many of the classes it belongs to. When using the model for classification, it is determined by the degree of similarity or divergence of the object with all classes, and a true-positive decision may be the membership of the object to several classes. The result of this classification may be that the object is not just rightly or wrongly relates or does not relate to different classes, both in the classical F-measure, but rightly or wrongly relates or does not relate to them in varying degrees. However, the classic F-measure does not count the fact that the object may in fact simultaneously belongs to multiple classes (multicrossover) and the fact that the classification result can be obtained with a different degree of similarity-differences of object classes (blurring). In the numerical example, the author states that with true-positive and true-negative decisions, the module similarities-differences of the object classes are much higher than for false-positive and false-negative decisions. It would therefore be rational to the extent that the reliability of the model to take into account not just the fact of true or false positive or negative decisions, but also to take into account the degree of confidence of the classifier in these decisions. In classifying big data we have revealed a large number of false-positive decisions with a low level of similarity, which, however, in total, contribute to reducing the reliability of the model. To overcome this problem, we propose a L2-measure, in which instead of the sum of levels of similarity we use the average similarity by different classifications. Thus, this work offers measures of the reliability of the models, called L1-measure and the L2 measure, mitigating and overcoming the shortcomings of the F-measures; these measures are described mathematically and their application is demonstrated on a simple numerical example. In the intellectual system called "Eidos", which is a software toolkit for the automated system-cognitive analysis (ASC-analysis), we have implemented all these measures of the reliability of the models: F, L1 and L2
The problem of environmental protection from the contamination by toxic products, contained in the exhaust gases, is one of the most topical in the modern world.
Nitrogen oxides and soot particles are the most toxic.
Getting into the environment and the human body, they cause heavy chronic disease and significantly impair the quality of animal and plant products. The developed gas purification system SCR, the technology of plasma purification of exhaust gases have not found wide practical applications because of their high value.
The study of papers dedicated to reducing exhaust gas toxicity shows that the use of combined means of purification, which usually include mechanical, thermal and catalytic methods of purification, is the most effective. Our work deals with the issue of purifying the diesel engine exhaust from fine particulate matter resulting in the combustion of fuel and oil motor partly.
The article notes that the carbon is not magnetic, so the use of a magnetic field acting as an agent for the purification of exhaust gas from the carbon soot particles is impossible. The purification in a centrifugal field requires the creation of structurally complex centrifuges, so it is ineffective. We consider the possibility of purifying the exhaust gases from the soot particles in the electrostatic field. The device presents the collecting electrode, which is shaped as a cylinder, and an axial central electrode, which is mounted on an insulated spacer within the cylindrical body. The study deals with the physical and mathematical simulation of processes occurring in the proposed device of the purification of exhaust gases. The equality of the Coulomb force and the Stoks force determines the magnitude of the electrostatic field strength that is necessary for the purification of exhaust gas from the soot particles. We have identified the desired length of the collecting electrode
The article discusses the implementation of a
software system to support management decisions
designed to organize the educational process in
higher educational institutions. We have completed
argumentation of the development and application of
a software system. This system was developed in the
department of the computer engineering of Institute
of computer technologies and information security,
Southern Federal University (SFeDU). The article
describes the algorithm of functioning of the system
and its structure. The software system includes
several subsystems and three external modules:
"Personal load", "Materials to the schedule", "Work
Plan of the Department". It provides basic
information about the developed modules, discusses
their purpose and functionality. Initial data for
modules were defined. The results of the work of
modules are confirmed by illustrations. The article
describes the work of the subsystems composing the
software system. These are a subsystem of data
processing, a subsystem of decision-making and a
subsystem of input/output. The structure of all
subsystems is detailed at the block level, the purpose
of blocks was determined. Resulting files of the
module work are generated in an XML-format and
can be converted into an Excel-format that
considerably facilitates a task of their subsequent use
and processing. The system and the additional
module possess the convenient functional interface
and, considering facilities on adjustment for the
concrete user, can be used in structural divisions of
various universities

In the soils of rice fields, eluvial gley processes
develop, which are manifested in redistribution of silty
particles along the profile, water-soluble humus,
mobile compounds of iron and phosphorus. Most
intensively, these processes are developed in meadowbog
soils, confined to closed depressions of the plains
plain. Meadow-black soils lying on elevated relief
elements have more favorable physical, physicochemical
and oxidation-reduction properties for
cultivating rice and accompanying crops in crop
rotation. The highest yield of rice is formed on high
checks and higher at 12,4 c/ha than on low ones
The article contain the peculiarities of testing asynchronous
generator with sixzone winding on the basis
of the asynchronous motor series 4A100S4 and analysis
of obtained characteristics. Circuit parameters of
the stator winding can significantly affect the characteristics
of the asynchronous generator. Asynchronous
generator was tested with a stator winding connected
star, autotransformer and sectional winding. Use chastising
windings opens the possibility of applying various
circuits of capacitors and the load to asynchronous
generators, which in turn affect the efficiency and stabilizing
properties of the electric machine. Asynchronous
generators to test with sectional winding by confirmation
of theoretical calculations for determine the
most optimal scheme under connect capacitors and
load, testing the stator winding. The volume of testing
for asynchronous generators standard is not defined, so
we proposed testing method, taking into account the
design features of the stator winding. Asynchronous
generators were tested with the help of special equipment
with the use of analyzer of energy power quality.
