	Modelování nelineárních aeroelastických jevů na konstrukcích Náprstek, Jiří ; Pospíšil, Stanislav ; Hračov, Stanislav The paper deals with the aeroelastic instability and non-linear post-critical behaviour of a two degree-of-freedom system. Detailed record
	Some properties applications of eigen functions of the Fokker-Planck operator Náprstek, Jiří Non-stationary solution of the Fokker-Planck(FP) equation leads to problem of eigen-values and eigen-functions of the FP operator. Problems of the asymptotic convergence related with stationary solution existence and the prospective metastability of the system are analysed. Detailed record
	Vaveletový rozklad nestacionárního náhodného signálu Fischer, Cyril ; Náprstek, Jiří The paper provides a support for the wavelet based approach for the analysis of the MDOF systems subjected to non-stationary excitation. It tries to cover the lack of input data in the form of the wavelet decomposition of seismic records. Detailed record
	Random inter well hopping of a single system with bistable elastic potential Náprstek, Jiří The response of a dynamic nonlinear single degree of freedom system with cubic characteristic to a combination of additive random Gausssian white noise and external deterministic periodic forse is studied. Detailed record
	Real and Markov processes in stochastic systems Náprstek, Jiří Markov process is a mathematical idealization and its exact properties cannot be found in any real physical processes. Detailed record
	Empirical mode analysis of the non-stationary response of the structure vibrating in the wind Pospíšil, Stanislav ; Náprstek, Jiří The paper describes the new method of analysis of the response of structure in the wind. Detailed record
	Dynamics of a spherical vibration absorber Náprstek, Jiří ; Pirner, Miroš Wind excited vibrations of slender structures can be reduced using assive vibration absorbers. If there is available only a limited vrtical space to install such a device, a spherical type of absorber can be recommended. Detailed record
	Instability onset of rectangular prismatic beams in the wind flow Pospíšil, Stanislav ; Fischer, Cyril ; Náprstek, Jiří This paper describes a part of theoretical and experimental researchdealing with the problem of the aeroelastic instability onset ofslender rectangular beams in the air stream, modeled as twodegrees-of-freedom. Detailed record
	Interaction of a PVC-bearing with a bridge structure Náprstek, Jiří ; Pirner, Miroš ; Fischer, Cyril Long-term observation of bridges supported by bearings made of syntheticmaterials reveals a steady horizontal deformation increase of theseelements. This process can be very dangerous for the bridge as a whole. Detailed record
	Modelling of seismic random processes with time variablefrequency content Náprstek, Jiří Seismic random processes are characterized by high non-stationarityand, in most cases, by a marked variability of frequency content. Detailed record
