We present a Computational Fluid Dynamics (CFD) model that predicts the sedimentation of activated sludge in a full-scale circular secondary clarifier that is equipped wi [...]

Two parameters of bone microarchitecture: volume of bone layer and fractal dimension were used. 42 human bone samples were cut to cylindrical testing samples of 8.5 mm th [...]

The contribution deals with an application of discontinuous Galerkin method to free surface flow calculation. Both the super- and sub-critical flows are studied for stead [...]

One of the main modes of bed load transport is saltation when particles hop up from the bed and follow ballistic-like trajectories. Mathematical models of saltation are m [...]

The possibility of localising and quantifying a damage in a vibrating structure based on measured vibration amplitudes of the first harmonic in some locations of the stru [...]

The paper deals with approximation of spatial distribution of mean downstream velocity of sub-critical turbulent flow in an open rectangular channel with rough bed. New f [...]

In order to simulate a launch, all space instruments undergo a vibration tests. Due to the fixing points in vibrating machines being different, adapters are used for each [...]

The Source-filter theory does not take into account many important circumstances for generating of vowels, e.g. the effects of source on filter. One of these effects is i [...]

In the paper, two methods for modelling machine tool drives with ball screws are shown and compared. There are common equation formulation and the multi-pole modelling. T [...]

The condition of stability of steady flow in rotationally symmetrical area is presented in the paper. The governing equation is Navier-Stokes and the continuity equation [...]

The paper describes the mathematical model of the thermodynamic process connected with the replacement of two different gaseous contents in a storage pressure vessel. The [...]

The simulation of the fluid flow through elastic pipes has a great application in a blood flow through human vessels – investigation of such phenomena as an atherioscle [...]

The paper deals with the numerical simulation of a turbulent compressible fluid flow through the two-dimensional model of a gap caused by the incorrect contact of screw [...]

Abstrakt: Paper presents mathematical model of two-dimensional electrolyte flow in interelectrode gap and calculation results for form electrodes with development geometr [...]
