This paper aims at presenting the systems theory-based approach to the learning (instructional) process. Such as approach is necessary, if one takes into consideration the the complex and holistic nature of the learning process. The presented modeling is ... see more

Context. The rapid development of nanotechnology puts forward new requirements for electronic optics systems. In modern electron-optical systems, a significant amount of complex electrodes with a geometric symmetry is observed. When calculating the&n... see more

A state-of-the-art thermodynamic database has been developed for multicomponent oxide systems. It can be used in combination with FactSage software to calculate the properties of metallurgical slags, glasses, ceramics, refractories, minerals, cements, etc... see more

A high-quality test has a balanced level of difficulty and can be completed by the respondent with their level of abilities. This study analyzed the test instrument used to measure students' mathematics abilities in the semester final exam on System of Li... see more

At production, collection and transport of low – pressure gas to deep water offshore platforms in sea conditions because of thermodynamic indices change in the system, complications are generated in connection with liquid phases – separation. These compli... see more

Context. The problem of correction for operation of strapdown inertial navigation system used for unmanned aerial vehicle is urgent because of further increased requirements to autonomous flight in blackout zones. The object of the study was to simulate t... see more

Context. The management of many economic and other “service” systems of random flows of “requirements” is based on theprediction of their efficiency, based on an estimate of the system states probability distribution. In a number of important practicalcas... see more

A problem of reducing expressions, which are received while solving the system of Navies-Stokes equations is discussed. An algorithm of equivalent reducing is proposed, based on the theory ofchain fractions

For the ideal Fermi gas that fills the space inside a cylindrical tube, there are calculated the thermodynamic characteristics in general form for arbitrary temperatures, namely: the thermodynamic potential, energy, entropy, equations of state, heat ... see more
