Our latest work is focused on image synthesis of metal foam micro-structures using the Wang tiles and Automatic tile design.

Our study provides novel approach to acquiring data used in biomechanical models along with dataset of hand muscle data. It also provides a tool for generating these data, relieving researchers of some tedious labor and possibly allowing for greater reproducibility of research.

The original mathematical model of the VVER-type reactor excited by coolant pressure pulsations was derived as the linear clearance-free model in couplings. Assembly clearances in the key-groove (K-G) couplings between the lower part of core barrel (CB3) and the reactor pressure vessel ...

Macroporous hydrogels with controlled morphology are widely used in biomedical fields, as drug delivery, tissue engineering, analytical and technical separations or responsive constructs. Porosity can be achieved by several methods. In the preparation of physical experiments it is made by salt&#x...

In modelling of rotating systems, the connection of the rotor to the stator part is often performed by means of coupling elements that behave nonlinearly, such as hydrodynamic and magnetic bearings, squeeze film dampers, etc. The Harmonic Balance Method (HBM) represents a tool for&...

This paper deals with the replacement of the titanium profile in the airplane door with the composite one. The aim of the project is the FEM analysis of the titanium T-profile integrated in airplane door and to design a composite part which will be lighter and stiffe...

In this paper we present a procedure to correct the gait disorder in a 4 year old girl with mild CP and spastic double monoplegia. Time series for movement of the patient were produced in the gait lab of Wigmore clinic in Yerevan (Armenia) and the orthoses were&...

Piezoelectric materials are increasingly used in industry in various applications such as stabilization, micro-positioning, shakers etc. Two main disadvantages are high demand on the input voltages and relatively small range of motion. There are presented two type of piezoelectric elements implem...

The human phonation is highly interesting phenomenon, where numerical simulations play an important role due to the practical inaccessibility of the vocal folds. This phenomenon is described by three physical fields ? the deformation of elastic body, the complex fluid flow and the ...

In this paper the mathematical modelling of fluid-structure interaction problems is addressed particularly with the interest paid to the biomechanics of human voice. The attention is paid to the precise approximation of the fluid flow, particularly in the glottal part, with the aid ...

Numerical simulations of the supersonic flow have shown the significant effect of the prescription of the outlet boundary condition. Simulations carried out for the standard computational domain with the output behind the blade cascade and/or for the computational domain corresponding to...

In axial turbine stages the secondary flows have an important impact on the drop of the stage efficiency. Significant sources of the secondary flows are shroud- and hub-seals. This paper deals with numerical simulation of the hub-seal leakage flow effect on the axial turbine s...

The paper describes the possible procedure of FEM calculation of hydrogel materials. The basis of the calculation is to perform a calculation with a common material model. Only after the application of boundary conditions is the material model incrementally changed to the desired. ...

Numerical calculation of collapse load (limit load) of a structure, made of elastic-plastic material, is often of practical interest. Standard approach is based on repetitive use of nonlinear finite element calculation, where the collapse load is determined iteratively. However, more efficient&#x...

The mechatronic modal hammer was designed and manufactured. Basic structure is relatively simple. However, suitable choice of mechanical parameters and smart control (feedback and feedforward) enables the device to achieve high parameter stability of impact excitation. The repeatability of the ex...
