Design of a wing model for flutter testing
Zíka, Jakub ; Šplíchal, Jan (referee) ; Navrátil, Jan (advisor)
Bachelor thesis deals with the design of a wing model for testing the dynamic aeroelastic phenomenon of flutter. The first two chapters of the thesis present theoretical introduction to aeroelastic phenomena and scaling relationships. The third part describes the whole model designing process based on similitude requirements to a real wing. Bending and torsional stiffness along with mass distribution are the most important wing properties where similitude should be attained.

Cognitive errors in mass media communication
Zíka, Vojtěch ; Křeček, Jan (advisor) ; Hladík, Radim (referee)
This work is based on an assumption that human decision-making process is following several approximate rules (heuristics) that causes predictable and systematic errors in judgement (cognitive biases). Although this stand point is typical for fields like behavioural economics or behavioural law and economics, there is no reason to not apply this logic also on other discipline like a mass media communication studies. This work offers an analysis of the information market where supply side is represented by producers of information (e.g. media organizations) and demand side is represented by consumers of those information (audience). The analysis is focused on factors that cause perceived description of a particular event can vastly differ from this event. One of those cognitive biases which cause different perception of the same media content is called hostile media effect. In respect to this effect, sympathizers with a socially controversial topic tend to perceive information in the mass media as hostile to their own opinion. Previous research concluded that hostile perception is mainly caused by a reach of information which is explained by the selective categorization - although individuals with different worldview can see the same content, they perceive it with a different valence. The valence of the...

Distributed order management for restaurants
Zíka, Jakub ; Kofroň, Jan (advisor) ; Horký, Vojtěch (referee)
Order management software is vital to restaurants and other order-based businesses to keep track of their finances and the demands of their custo- mers. Many such products are available in the Czech market; however, it is often difficult to modify these existing solutions or interface them with new or different systems. In this thesis, we design and implement a new order management system called EasyPub. EasyPub works on GNU/Linux and Microsoft Windows operating systems, and allows external programs to ac- cess information stored within the system through an open communication protocol. Its creation is beneficial and contributes to innovation in the area of restaurant software. 1

Merleau-Ponty's dialogue with the science
Lockenbauer, Jan ; Novotný, Karel (advisor) ; Zika, Richard (referee)
The present essay aims to elucidate Merleau-Ponty's attitude towards science in his early published works. Being a phenomenologist, he refuses to understand science as a tool to discover general natural laws valid once for all and for everyone which are supposedly to be found in the reality inaccessible to our so called naive experience. However, he esteems the gestalt psychology because in his eyes this scientific field founds its conceptions on the lived-world without mistaking these very conceptions as only reality when compared the lived-world itself. We aim to apprehend Merleau-Ponty's attitude relative to these two types of scientific approach as a dialogue through which he establishes his own thinking. The research starts with Husserl's discovery of the lived-world, or, in other words, of the original soil of our experience preceding all philosophical reflexion as well as all scientific construction. This effort ought to helps us with understanding the reasons of Merleau-Ponty's critique of causal thinking and realistic science. In the next step, we will present the notions of "behavior" and "form" used in the framework of gestalt psychology. This elucidation will gradually lead us to the outlines of the manner in which Merleau-Ponty extends this psychological concept to the field of philosophy. Last...
