	Effect of time integration on dispersion properties of quadratic finite elements in elasto-dynamics Kolman, Radek ; Okrouhlík, Miloslav ; Plešek, Jiří In the paper, the dispersion relationships of plane quadratic finite elements for central difference method and Newmark's method are derived. The graphs for the mesh density and time step check wtih respect the dispersive behaviour are presented. Detailed record
	The effect of input pulse shape on stress wave propagation in a thick plate Hora, Petr The effect geometrical dispersion is that the energy in a wave-packet propagates at different speeds depending on its frequency. It is shown that duration of a wave-packet increases linearly with propagation distance and also that the duration of a wave-packet after a given propagation distance depends on the input signal. Some conclusions are made concerning the Lamb wave propagation in a steel plate. Detailed record

	Material assessment of thin wall constructions by means of contactless Blaháček, Michal ; Landa, Michal ; Zídek, Jan ; Urbánek, Přemysl The report deal with laser emitted acoustic emission (AE) sources reproducibility. Relation between the AE sources parameters and the source - transducer distance is observed. Symetric and antisymetric elastic wave modes decomposition using bandpass f Detailed record
	The study of dispersive properties of media dsicretized by LISA-2D code Ježdík, Roman ; Červ, Jan Dispersional and anisotropic properties of media discretized by LISA-2D code are studied. Detailed record
	Flow and dispersion in a street canyon simulation Jaňour, Zbyněk ; Holpuch, J. ; Střižík, M. Detailed record
	Air pollution by lead from KOVOHUTĚ metal work in the complex terrain Holpuch, J. ; Jaňour, Zbyněk ; Civiš, S. ; Střižík, M. ; Kunický, Z. Detailed record
