Assessment of a Heterogeneous Environment

An approach to the assessment of a heterogeneous environment in accordance with the proposed concept of a heterogeneous environment is described. The classification of industrial heterogeneous media by technological feature is proposed. The processes described by the proposed approach include the process of metal cutting, surface plastic deformation, chemical-thermal treatment, formation of coatings, welding, most of the processes that change the level and gradient of hardness and internal stresses in the surface layer of the material. Application of the proposed principles makes it possible to find new directions in the study of such processes.

ELECTION AND GENETIC PARAMETERS OF THE INTENSITY OF MILK PRODUCTION IN COWS

The study of the main technological feature of the Kholmogorsky breed of the Tatarstan type-milk ejection intensity-showed that its increased variability is characterized by high-blood crossbreeds, as well as animals of the Astronaut and Sovering lines. The high and low genetic potential of parental productivity reduces the variability of milk ejection intensity. However, selection for an increase in milk content will not be accompanied by an improvement in the intensity of milk ejection, since the established phenotypic correlation is mainly negative or positive at a low level. In this regard, it is necessary to control both productive and technological characteristics.

DIDACTIC POTENTIAL OF MOBILE LEARNING IN HIGHER EDUCATION

The growing availability of modern mobile smartphones and tablet computers is leading to an increase in the volume of content users consumed, including educational content. The development of mobile technologies opens up many opportunities for learning in higher education institutions. However, the use of mobile learning in student training should not be a spontaneous process, it is necessary to create pedagogically substantiate approaches and training methods. This article analyzes and interprets the results of existing research in pedagogy regarding the didactic potential of mobile learning in higher education system. A classification of didactic properties and functions of mobile learning is developed and proposed. The main didactic properties of mobile learning include: by the didactic feature of mobile learning — ten properties; by the technological feature of mobile learning — eleven properties. The main didactic functions of mobile learning are: by the didactic feature of mobile learning — eleven functions; by the technological feature of mobile learning — five functions. The didactic potential of mobile learning, due to its inherent didactic properties and functions, makes the educational process more effective, as well as contributes to the guaranteed achievement of students’ educational goals and planned learning outcomes.

An Interdisciplinary Research on Students’ Employability in Technology Education to Advance Higher Education Enrollment Sustainability

Nowadays, with respect to the rapid development of technology education, the rigorous issue of students’ employability, and the swift awareness of University Social Responsibility (USR), a majority of higher education institutions have necessarily dedicated themselves to discovering the most effective sustainable strategies in order to survive in the current hyper-competitive and low birthrate era. Therefore, this research creatively employed the Social Cognitive Theory (SCT) to interdisciplinarily and mutually assay the correlationships among technology education, students’ employability, and institutions’ developmental sustainability. Further, it also cross-applied and consolidated the Factor Analysis (FA) approach and the Entropy Analysis (EA) model to comprehensively probe in-depth into the results from a large-scale questionnaire completed by various experts in order to delve into the most critical determinants of students’ employability in technology education to advance higher education enrollment sustainability. As a result, the most valuable finding of this research is to directly point out “poverty, unemployment, and educational equitability” as the three most materially considered factors by students during their higher education institution selection process. As a result, higher education institutions have necessarily developed the Concurrent Usages Convenience Technological Feature (CUCTF, Information Immediacy Usability Openness Technological Feature (IIUOTF), Course-Professionalization Technology Assessment (CPTA), and Course-evaluation Technology Analysis System (CTAS) of technology education to strengthen the covered Self-control Capability (SCC), Communication Expression Ability (CEA), Active Attitude and Ambition (AAA), and Problem-solving Ability (PSA) of students’ employability to interdisciplinarily explore the most critical determinants of students’ employability in technology education to advance higher education enrollment sustainability.

INSTALLATION FEATURES OF SPATIAL LATTICE METAL COVERING OF A PRODUCTION BUILDING IN LIMITED SPACE CONDITIONS

A version of the project for the installation of the spatial structure of the coating of an industrial building was developed. The technological feature of the project was the presence of cramped working conditions. The feasibility study of the methods of assembly and installation of the coating, taking into account the peculiarities of the construction of the coating, the features of the construction site and the needs for lifting machines, showed the eff ectiveness of the installation of the coating with enlarged blocks assembled on the ground. Mounting the unit using a traverse allowed to reduce the estimated height of the hook and select a crane that does not diff er in the high cost of rent. It became possible to apply the adopted installation scheme provided that an individual design of the beam was developed. The calculation and design of the traverse itself was performed, as well as the calculation of the enlarged unit for the installation situation.

XXIII Международный симпозиум Нанофизика и наноэлектроника", Нижний Новгород, 11-14 марта 2019 г. Вертикальный полевой транзистор с управляющим p-n-переходом на основе GaAs

The first results on the creation of an original power GaAs field-effect transistor with a vertical channel controlled by the p-n junction are presented. The main technological feature is the use of two separate processes of epitaxial growth in the formation of the transistor structure. The part of the transistor containing the drain, drift and gate areas is grown by liquid-phase epitaxy. The technology of organometallic gas-phase epitaxy is used to form the areas of the channel and the source.

TECHNOLOGICAL FEATURES IN THE LAMINATION OF BANDS

This paper presents an experimental and practical study of the lamination of aluminium bands, determining the widening and the influence of various factors upon the widening. Two samples were laminated from two aluminium alloys, in the shape of bands. The points of the widening graph were drawn depending on the relative reduction for the two samples. For practical purposes, special importance is given to the preliminary determination of the value for the widening. Various factors influence the widening in lamination: the increase in the absolute reduction, the distribution of the reduction on passings, the shape of the deformation area, the ratio between the width and the length of the deformation area, the diameter of cylinders, the width of the semi products, the coefficient of friction, the lack of uniformity in the deformation. The widening is an important technological feature in the lamination process which needs to be monitored taking into consideration the factors that influence it in order to obtain finished products with high dimensional precision and reduced execution tolerance.
