Production of polymer optical elements and their analysis by electron microscopy
Motlová, Tereza ; Sobola, Dinara (referee) ; Pokorná, Zuzana (advisor)
There is a great demand nowadays for optical components with high quality and efficiency, yet as lightweight and low-priced as possible. These requirements are met by micro-optical elements. The aim of this work is to design and manufacture a polymer micro-optical element for aberration correction in a Czerny-Turner type spectroscope that had previously been constructed at the Institute of Scientific Instruments of the Czech Academy of Science. The design was carried out with the help of of the ZEMAX OpticStudio ver. 21 optical design software. The element was manufactured using the technique of two-photon polymeration and nanoimprint lithography. Surface quality, profile verification and presence of defects was checked using confocal microscopy and scanning electron microscopy. The micro-optical element was then successfully incorporated into the spectroscope.

Roman forts and fortresses in the Nile valley
Šurinová, Miroslava ; Musil, Jiří (advisor) ; Titz, Pavel (referee)
This paper deals with roman fortifications in the Nile valley from the mouth of Delta to site of Qasr Ibrim located between first and second cataract. Period described in this paper can be limit by two dates. Beginning lay in the year 30BC, when Egypt became a roman province. The end of this period is year AD 641, when the city of Alexandria capitulated to Arab conquerors. The paper focuses on the architecture of forts and archaeological excavations.

Water Projects on the Nile in the 19th Century and Their Influence in British-French Relations
Mazanec, Jakub ; Valkoun, Jaroslav (advisor) ; Šedivý, Miroslav (referee)
Jakub Mazanec Water Projects on the Nile in the 19th Century and Their Influence in British-French Relations At the beginning of the 19th century, the era of building of the first modern hydraulic projects on the Nile in Egypt was launched. During the first half of the 19th century, France had a significat influence on Egypt, which was also reflected in hydraulic projects on the Nile. On the contraty, since the British ocuppation of Egypt in 1882 until the end of the century, the influence of London dominated. The need of water and the construction of major projects shaped the policies of France and Great Britain towards Nile basin. The aim of this thesis is to prove or refute the hypothesis, that hydraulic projects realized on the Nile during the 19th century represented a significant issue of friction between France and Great Britain. And at the same time this thesis tries to prove a change in the perception of water from the side of Egyptian authorities.

Imagination of infinity
Semerád, Martin ; Pauza, Miroslav (advisor) ; Sak, Petr (referee) ; Jirků, Petr (referee)
This work deals with a basic question of modern science and it is its indefectibility. Quality of education is reduce to an evaluation of conformity to a common known knowledge and its quantity representation. Seeds of this long process go back to an ancient academia of Gondisapur established in an Arabic world. Author proclaims that the main goal of philosophy is to show, that this is not the only way of thinking and in the same time that the main goal and power of phenomenology is to apply the transcendental epoche to overcame the truth in its regularization shape. The hardcore of modern science is located in the world of mathematics and a lot of thinkers find the Math as a land of pure sureness - the core of this work in an opposite proofs, that in fact nowadays math is all, but the correct way of thinking. The two examples are explicit: the Pythagorean Theorem and the Sum of the geometric row. This work brings a quite new view on the mathematical problem of "the point" and "the nothing" as a border of things. In the second part uses as a frame of its topic the first 18 §§ of the work "Paradoxes of the infinite" by Czech mathematician of German mother tongue Bernard Bolzano. The important idea of this study is a new ontological view on the set of prime numbers.
