Numerical two-dimensional two-fluid MHD simulations of dynamic magnetosphere-ionosphere (MI) coupling have been performed to model the effects imposed on the auroral ionosphere by a powerful HF radio wave transmitter. The simulations demonstrate t

The influence of the finite ionospheric conductivity on the structure of dispersive, nonradiative field line resonances (FLRs) is investigated for the first four odd harmonics. The results are based on a linear, magnetically incompressible, reduce

In the global fuel economy, new challenges concerning the use of alternative (vegetable) fuels in the internal combustion engines are starting to arise. The important issue is to meet the new limits on four main pollutant emissions from a diesel engi

Phenomena accompanying the self-ignition period have been and are the subject of extensive research in this area. They are usually carried out in constant volume pressure chambers or in reactors with constant air flow. Such tests are considered to be

Despite the fact that more than a hundred years have passed since the first design of the CI engine appeared, its optimal design has not yet been achieved. It is still the subject of constant modernisation in order to meet the new expectations of use
