Effective up-skilling teachers who are involved in teaching software engineering should take into account the challenges of teaching practice. Despite the long practice of organizing the teaching of software engineering and computer science in educational organizations in Russia, relevant up-skilling courses are not methodologically supported. The paper introduces an active, practice-oriented approach to organizing up-skilling courses for teachers who teach software engineering and development. The authors developed the level model for the advanced up-skilling teachers interested in mastering and delivering modern technologies of Agile software engineering and development. Authors implemented the model for organizing teachers’ up-skilling courses in intensive schools for engineering, development, design and management of software products

The article describes a model of an information system for assessing and forming the structure of a dairy cattle herd. Based on a brief description of this task, a logical model of a relational database is built using predefined SQL data types. Based on object-oriented modeling, a system behavior model is developed, presented in the form of a UML diagram of use cases and sequence diagrams. The option of using this model in the form of a local information system and the possibility of its integration with existing software systems is considered. The correctness of the model is confirmed by the developed local information system of the aforementioned assessment of the herd structure.

This article assesses the influence of the error in the data representation in the control contour, arising from their limited capacity, on the output voltage of a pulse voltage stabilizer. Also, in this article, an assessment is made for the linear control law. The experimental results of the study of the influence of bit depth analog-to-digital conversion on the stabilizer operation are presented.
