	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
	Some properties of the FEM applied on structures with random imperfections Náprstek, Jiří Numerical analysis of thin walled systems using FEM can be based on the Arc Length Method or on simulations supported by Bayesian algorithm of posterior probabilities. Detailed record
	Flutter instability due to nonconservative and gyroscopic forces Náprstek, Jiří Theoretical explanation of a flutter effect as a stabilityloss of a slender beam response due to its aeroelasticinteraction with an air stream. Detailed record
	Aeroelastic instability of a system with nonconservativeand gyroscopic forces Náprstek, Jiří ; Pospíšil, Stanislav Mathematical model of stability loss due to flutter effect.The origin of instability consists of nonconservative andgyroscopic forces. Detailed record
