USING HELIOTROPIC SOLAR PANELS FOR AUTONOMOUS POWER SUPPLY OF CONSUMERS

Posted in 2017, ENGINEERING, Issue № 7(61) July 2017 | 0 comments

More and more individual regions are investing in renewable energy. There is an objective threat of climate change due to the use of combustible fuel. This means that more and more countries will switch to ecologically safe and renewable energy – solar, wind and tidal.

The purpose of this work is to discuss the use of heliotropic solar panels for autonomous power supply to consumers, to analyze the market of solar panels used as a stand-alone power source for street lighting and charging stations under the conditions of large angles deviations in the solar path diagram for regions remote from the equator.

Heliotropic installations are an effective way to control solar panels by adjusting its position relative to the sun. This is especially true for regions remote from the equator. The following paper contains financial forecast for the solar energy market and the design of a solar installation of the heliotropic type. The comparison with a classical stationary installation is provided.

ORGANIZATION OF THE EXPERIMENT ON VERIFICATION OF PEDAGOGICAL CONCEPT FOR THE DEVELOPMENT OF STUDENTS’ SPEECH

Posted in 2017, Issue № 7(61) July 2017, PEDAGOGY | 0 comments

The article contains the description of preparation stages of the experiment on the verification of the pedagogical concept for the development of university students’ speech. Due to the fact that the course “Russian Language and the Culture of Speech” is practical-oriented, a whole complex of activities and tools is required to evaluate the efficiency of the pedagogical technology. The main goals and tasks of the experiment and the components of the training model are also presented. The author comes to the conclusion that it is necessary to check both students’ communication skills in terms of external speech and the level of internal speech development (internal plan of action).

TRADITIONS OF DIALOGUE IN RUSSIAN AND EUROPEAN CULTURE

Posted in 2017, CULTURE STUDIES, Issue № 7(61) July 2017 | 0 comments

The author analyzes traditions of using dialogue as a means of communicative interaction of two equal consciousnesses, aimed not only at discussing and solving problems, but also at the development of the participants themselves. Emphasizing the longstanding experience of forming the positive role of the dialogue in European public practice, the author discusses the reasons for the insufficient development of this cultural and historical phenomenon in Russia based on the specifics of the Russian socio-cultural context.

DESIGNING MODELS FOR QUALITY OF EDUCATION EVALUATION IN INCLUSIVE PRESCHOOL INSTITUTIONS

Posted in 2017, Issue № 7(61) July 2017, PEDAGOGY | 0 comments

We identified indicators that determine the correspondence of educational activities in preschool institutions to contemporary requirements based on the analysis of trends in the measurement of educational resources and the evaluation of the quality of education in pedagogical systems. It has been shown that educational monitoring is an important tool in the evaluation of the quality of educational activities in a preschool institution. The multi-functionality of monitoring is considered from the perspective of consistency, integrity, dynamism, representativeness, methodical unity and complexity. The formula for the evaluation of the quality of education in an inclusive preschool institution is provided. It is represented by a combination of coefficients of psychological and pedagogical, personnel, organizational and pedagogical conditions of educational activity on the formation of a developing subject and spatial environment. The article presents an algorithm for designing a model for the evaluation of the quality of education in a preschool institution with regard to social and educational reality.

RECOGNITION OF NATURAL OBJECTS WITH FRACTAL SURFACE

Posted in 2017, ENGINEERING, Issue № 7(61) July 2017 | 0 comments

This research is devoted to the problem of recognition of vegetal objects with a fractal surface. One of the areas of this research is the development of inexpensive sensors capable of instantly recognizing specific components of vegetal material with an uneven surface of the object. Much attention is paid to object modeling and mathematical recognition methods. The mathematical base for a new approach to the analysis and design of technological processes of agricultural crop processing is proposed. The problem of recognition of vegetal objects which are close in shape to the real ones in the shadow contour is considered.

APPLICATION OF K-MEANS AND G-MEANS CLUSTERING ALGORITHMS IN OBJECTS RECOGNITION

Posted in 2017, ENGINEERING, Issue № 7(61) July 2017 | 0 comments

The application of clustering by families of k-means and g-means algorithms in problems of recognition of airborne objects under the conditions of incompleteness and unreliability of data is considered in the article. The choice of these clustering algorithms is substantiated. The importance of clustering in recognition problems is emphasized. A research sample was created and used to demonstrate the efficiency of clustering by families of k-means and g-means algorithms. The analysis of the results obtained during clustering is carried out. The perspective of the forecasting method in problems of airborne objects recognition is revealed.

STUDY OF CHANGING GEOMETRIC DIMENSIONS OF METALLIZED CYLINDER MUFFS DURING STRENGTH TESTING

Posted in 2017, ENGINEERING, Issue № 7(61) July 2017 | 0 comments

One of the ways to improve physical, mechanical and operational characteristics of cylinder muffs of internal combustion engines is metallization implemented with the help of cutting on the inner part of the working surface of counter-helical grooves friction with the subsequent surfacing of copper. We conducted experimental research on axial deformations of the muff, as well as hydraulic tests showing that the parameters of the muffs remain within limits to determine the effect of the technological process of the muff metallization on its strength.

DEVICE FOR DIAGNOSTICS AND MONITORING OF POWER TRANSFORMERS IN THE WORKING MODE

Posted in 2017, ENGINEERING, Issue № 7(61) July 2017 | 0 comments

At present, timely diagnostics is a necessary condition for reliable operation of various electrical devices. Thus, it is necessary to control such quantities as short-circuit resistance (SCR) and leakage inductance for power transformers of high power, for example, in transformer substations. Their control over the whole lifetime allows detecting possible damage to the transformer after emergency situations, because at the time of short circuit protective devices do not instantaneously disconnect the transformer and its shock windings briefly flow shock currents subjecting the transformer elements to large mechanical overloads, which can lead to the displacement or deformation of windings and core.

INFLUENCE OF ELEMENTS OF THE YIELD STRUCTURE ON THE PRODUCTIVITY OF RICE VARIETY OF THE CONTROL NURSERY GARDEN

Posted in 2017, AGRICULTURE, Issue № 7(61) July 2017 | 0 comments

The results of the structural analysis of rice varieties harvest for 2015-2016 are presented in the article. Analysis was conducted on the basis of the stem density, the number of head spikelets, the mass of 1000 grains determining the biological yield. The regression analysis of 96 rice samples allowed establishing the relationships between the structure of elements and their yield. The graphs show the curvilinear dependences of yields on a number of characteristics. The maximum yield was formed for samples with a number of panicle spikelets: More than 90 pieces in 2015, more than 100 pieces in 2016. In 2015, samples with a mass of 1000 grains of 30-45 g were more productive, and in 2016 grains of 20-35 g. In 2015, the most efficient density of stemstones reached 250-400, in 2016 – 300-450 stems per 1 m2.
