Numerické modelování sdružených úloh diferenciálními metodami vyššího řádu přesnosti

The objective of this Doctoral Thesis was to develop, implement and test new algorithms for the large-scale solution of nonstationary compressible MHD equations based on higher-order discontinuous Galerkin (DG) methods. The basis for the new methods will be the discontinuous Galerkin methods...

Nikolayev, Denys
Numerické modelování speciálních antén pro použití v biomedicíně

Progress in implantable and ingestible wireless biotelemetry requires versatile and efficient antennas to communicate reliably from a body. We propose an miniature antennas immune to impedance detuning caused by varying electromagnetic properties of the surrounding biological environment. It is design...
