Computer assisted calculations consists in applying software for the simu-lation of models of certain devices and later analysing their behavior under given conditions corresponding to real working conditions in a specific environment.The paper proposes a circuit model of 2G YBCO super-conducting tape created in the PSpice program. The model consists of passive blocks and active user blocks of analogue behavioural modelling (ABM). ABM blocks calculate the conductances, the currents of the indi-vidual layers of the superconducting tape, its thermal capacity, the heating power, the cooling power and resulting temperature of the tape. The model uses table of thermal power density passed to the liquid nitrogen vs. temperature. Smooth transition of the YBCO superconductor layer into the resistive state is described by Rhyner’s power law. The developed model was used for generating waveforms of thermal and electrical quantities.

The results of kinematic analysis of the ASz-62IR radial engine crankshaft was presented. In addition, the one-dimensional model of the working cycle of the engine was created in AVL BOOST system. Differences in the waveforms for each pistons causes the differences in the filling process what reflects in the mass of the load supplied to cylinders. Additionally, due to one dimensional model computation. The results show differences in the value of maximum pressure. This causes differences in mean effective pressure of up to 4% and which also affects the vibrations of the whole engine.

We apply window Data Envelopment Analysis (DEA) to the solution of the problem of assessment of the efficiency of regional production systems in Southern Russia. The proposed method allows to monitor the changes in efficiency of regional economic systems throughout time and has a high discrimination power. The simplicity of the technical implementation of the proposed method and the availability of the necessary software for its use allow one to hope for its wide implementation in the modern practice of regional environmental management.

In this paper the results of Matching Pursuit (MP) Octave algorithm applied to noise, vibration and harness (NVH) diagnosis of rolling bearings are presented. For this purpose two bearings in different condition state were examined. The object of the analysis was to calculate and present which energy error values of MP algorithm give the most accuracy results for different changes in bearing structures and also how energy values spread in time-frequency domain for chosen energy error value.

The article presents issues relating to designing and improvement of manufacturing processes based on a modelling and simulation method. The 3D model of a production line has been designed and simulation experiment, conducted on the Arena model prepared in a versatile package for modelling and simulation of manufacturing systems and representing functioning of the system, has been carried out. The results obtained from the experiment and analyses of time and ergonomics of work at a work station were subject to multi-criteria assessment based on a point-by-point method of assessment according to Yager.
