Description
In the article on example of the Department of basements and foundations of Kuban State Agrarian University (KubSAU), we have discussed issues of preparation of final qualifying works for bachelors and masters in “Construction” specialty. The final qualifying work (the diploma project) is performed by bachelor at the final stage of study. Final stage (diploma designing) provides individual work of undergraduate students on solving tasks under the guidance of experienced teachers and leading construction industry professionals invited to lead to the degree designing. The general organization of bachelors’ diploma projects entrusted to the Deanery of Faculty of Civil Engineering and graduate departments. Topics of diploma projects are defined by graduating department after passing the Bachelor pre-degree practice. The article gives examples of the diploma projects in the Department of basements and foundations, as well as it shows the composition of the department that prepare bachelors, the procedure for appointing the heads and consultants. Separately, the article describes the organization of the preparation of master’s dissertations for post-graduate students who study at the Department of basements and foundations. Education of masters is conducted on two master programs: "Maintenance and reconstruction of buildings and structures", "Theory and Design of Buildings and Structures". For performing master's dissertation research a supervisor has to be selected from among the doctors and candidates of sciences. The article presents the main directions of masters’ dissertations, their exemplary topics, as well as performs stages, terms and procedure of public protection

THE FOUNDATIONS FOR PROGNOSES METHODOLOGY AND FOR INFORMATION SYSTEM EFFICIENCY ESTIMATION
DescriptionThe methodological, theoretical and applied aspects of making prognoses and estimation of information systems efficiency are under consideration in the paper. These ones are based on the original models of the principal constitutive of human factor, those are the preferences in the form of the matrix mechanisms of the complex estimating with the enlarged functional possibilities

Description
The article deals with the reliability of the functioning of the equipment of the power supply substation, and the determination of the probability of uninterrupted supply of electricity to consumers. The following are presented: models of failures of separators, models of short-circuit failures, models of failures of disconnectors. Two statistical series for sudden and gradual failures are singled out. The reliability theory is shown as the main distribution of fail-safe time for sudden failures. The conclusions on the presented models are made and the suggestions on introduction into production are given. According to the presented models, it is possible to judge the reliability of the station's operation, which is necessary for implementing measures to improve the reliability of electricity supply in network companies

THE BASICS OF CALCULATING THE PROBABILITY OF FAILURE-FREE OPERATION OF SUPPLY BUSES AND BUS SECTIONS
DescriptionIn agriculture, the high reliability of electricity supply is necessary because of its main feature production is associated with biological objects. The change in the state parameters can lead to a sharp decrease in the productivity of the biological system or, in general, to the death of it. The following enterprises are particularly critical to the reliability of power supply: dairy farms, hothouse complexes, incubators, grain storage sites, finished products and much more. The article presents: models of failure of switchable busbar, models of failure of supply buses; formulas for the calculation of reliability indicators, the calculated values of the probabilities of failure-free operation of individual elements, analysis of the values obtained, conclusions were made on the models presented and suggestions were made for introduction into production, energy conservation was associated with reliability of electrical installations
