New trends in internet marketing
Linc, Zdeněk ; Mikeš, Jiří (advisor) ; Peterka, František (referee)
This thesis deals with the topic of new trends in internet marketing. The theoretical part describes the current developments in the areas of Internet marketing display advertising, contextual advertising, SEO, social networks, mobile marketing, discount portals, price graders and describes their benefits to the overall concept of marketing. In the practical part is then discussed in detail testing of Garnier lotion, which was carried out via the Internet. In the practical part of it is used for various points of theoretical knowledge about the behavior of Internet users and is also based on the results analyzed. The practical part will demonstrate the benefits of the Internet for product testing and indicates the direction in which he could take on Internet Marketing.

Peterka, František ; Král, Petr (advisor) ; Raška, Ondřej (referee)
This paper is divided into 3 parts. First part defines the interactive media and describes particular types of internet and mobile media. The second part is focused on interesting projects in the Czech Republic, which offer new possibilities of internet and mobile advertising. The last part describes the project www.golfeurope.cz and its starting campaign with using the interactive media.

Motion of the dynamic impact damper
Peterka, František
Properties of the tuned dynamic impact damper is studied by numerical simulation. Different regimes of the system response on the harmonic excitation is evaluated and regions of existence and stability are ascertained. Specified behaviour as grazing, period doubling, saddle-note and Hopf bifursations are explained.

Oscillations of systems with clearances and prestressing
Půst, Ladislav ; Peterka, František
Mechanical 1DOF nonlinear systems with clearances and prestressing are analysed by means of response curves, gained by numerical simulation. It is shown that response curves of systems with prestressing have smaller amplitudes than those of systems with clearances and have more complicated form. Shape of main resonance peak of system with clearance corresponds to the hardening spring, that of prestressed system corresponds to the softening spring.

Oscillator with Hertzs model of soft impacts
Peterka, František
Dynamic properties of the mechanical system with one degree of freedom containing soft stop are investigated. Dynamical impact model respects the non-linearity of the restoring contact force between solid bodies as function of deformation according to the Hertz theory. The explanation of the system motion behaviour, when static clearance decreases up to negative values, which express the static prestress, is the main aim of this paper.
