A light source with variable intensity
Koždoň, Jakub ; Mojrová, Barbora (referee) ; Boušek, Jaroslav (advisor)
This work is focused on description how the light impact human live, description of light sources and finally design and construction of light source with adjustable colour temperature and luminous flux. In introduction is mentioned the process of vision and how the light impact humans. In next part is characterization of currently used light sources, their construction, properties, benefits and drawback with their main parameters. Important part of this chapter is more extensive description of light emitting diodes with their operational parameters. The last two parts is focused on design and measuring the parameters of created light source with adjustable colour temperature and luminous flux and evaluating the results.

Modelling of the Visual Perception
Faruga, Michal ; Hemzal, Dušan (referee) ; Kolář, Radim (advisor)
This diploma thesis considers with human vision and human eye. It takes into account both anatomic view and physiology standpoints. There is, among others, description of optical processes occurring in the organ of the sight mentioned in the work. The human eye suffers from optical defects – aberrations – that are able to degrade the retinal image and ultimately visual performance. Substantial part of the text deals with these aberrations. There are also analysed possibilities of their elimination using an inverse aberration. Work also assumes opportunity to optical modeling to calculate distorted images from ocular aberration data. Practical part consist of software application created using Matlab environment ver. 6.5 as well as full documentation. The examples of outputs procured using this application are published. Both software application and detail documentation are included on CD.

Ontological-ontic Concept of Conditions and Prerequisites of Inauthentic Dasein Demonstrated by the Example of Inauthentic Work of Art
Krcha, Martin ; Jirásková, Věra (advisor) ; Semrádová, Ilona (referee) ; Štampach, Ivan (referee)
The thesis deals with the issue of authentic or inauthentic work of art in the context of philosophy of authentic / inauthentic mode of existence (Dasein) as it was developed by Martin Heidegger in his Time and Being. The reason for addressing this issue is an effort to open the possibility of understanding authenticity or inauthenticity of individual Dasein in the manner which grasps it in the act of its performance, i.e. as a singular event. Thinking of authentic / inauthentic work of art demonstrates the limits of approach which understands authenticity only as certain originality or "selfness" which should belong to something authentic or inauthentic, almost like its accident. This thesis is therefore concerned with what is revealed if the concept of authenticity is transposed to a work of art. Since it is the subject who can make the act of performance of authenticity happen, the author and the recipient of the authentic / inauthentic work of art are problematized as well. When dealing with the work of art with respect to its temporality (historicality) or its being, the thesis also provides room for the issue of perception of the work of art. The resemblance of the author and the recipient is thus revealed and so is the necessity to learn to see not only artworks as such but to see them...

Virtuality and Construction of New Visuality
Hunčovská, Hana ; Fišerová, Michaela (advisor) ; Černý, Vladimír (referee)
This dissertation focuses on the problematic of the use of specific virtual representational methods and their influence on the construction of the new visuality. The aim of this dissertation is to show how computer simulations and visualizations used in medical imaging change the way of our apprehension of the world. Nowadays, within academic circles we witness both optimistic and sceptic theories concerning the effects of integration of computer technology and human apprehension. In this work we would like to answer the question about the type of knowledge we gain through virtual visualizations and we would like to prove that virtual simulations don't necessarily have to be a threat but, on the contrary, by developing visual imagination they can support new, creative apprehension of reality. Key words Linear perspective, logic of database, narrative, rhizome, scopic regime, simulation, simulacrum, virtuality, vision, visuality, visualization
