The Architecture of the Virtual
Halinár, Matej ; ArtD, Vít Halada, (referee) ; Kristek,, Jan (advisor)
Architecture Jail Escape It is a specific device for futuroptimist people based on the philosophy of posthumanism and transhumanism, a version of their own faith in endless life on the net. It is a belief in the possibility of technological transformation of humanity that will allow us to overcome our physical and biological limits. Clause 2.0 is architecture for pioneers - the protagonist of this transformation - enabling the longest and most complete stay in virtual reality. This avant-garde is anxious 2.0. Escapist personalities of digital age soldiers are looking for a haven and their own version of the world in the cyberspace. They create a vision of paradise and colonize (cyber) space without the political consequences of the finiteness of the physical world and the exhaustion of natural resources. They live on the frontier of the being, and they want to unburden themselves and merge with the world they understand more. They fight with their own brain and body that cannot break away from the world. The endlessness of the virtual space has the limits of body and senses. Long-term stay in a cyberspace is a loss of sense of time and space. This monastic life in clause 2.0 is able to keep them in shape, by observing the ritual, the physical performance of walking that they must undergo so that they can exist every day in their version of the digital monastery. These versions are infinite, and they can be ritually traced among them. Clause geometry isolates them from one another. The clause is a monastic concept that allows the people to live hermetically, as well as the physical world. The gateway to the virtual space is a "zero architecture" - a room, a cell, a cube on a 4x4 meter plan, rid of any visual architectural site. It provides only a flat floor as the reflection point for an endless virtual world and four walls and a ceiling with a corresponding thickness for a sufficient separation from the outside world. The world of infinite freedom opens behind this "zero architecture". It seems that not through "architectural innovation and political subversion" a modern architect's dream of architecture will be realized as machines for the liberation of man but through the abandonment of physical architecture as such. The prospect of "zero architecture" opens up a space where the new architecture will no longer be "luxuries and good homes, not the architecture of separation and imprisonment, but it will ultimately be the architecture of freedom.

Basic notions of the calculus by Newton, Berkely and their followers
Mixa, Lukáš ; Kvasz, Ladislav (advisor) ; Dvořák, Petr (referee)
Seventeenth century is important not only for mathematics but for European social development in general. This thesis offers an overview about development of mathematics in the seventeenth century England. I present only those mathematical discoveries, which were relevantfor the work of Isaac Newton. In the first part I show the construction of logarithms by John Napier, Henry Briggs and Gregory Saint-Vincent. The second part is dedicated to methods of tangents and quadrature. I describe works of Pierre Fermat, John Wallis and Isaac Barrow. In the third part is shown how Isaac Newton used the mentioned findings for the development of the calculus. I use this example to demonstrate, that historical approach offers an illustrative connection between geometry, algebra and mathematical analysis and can be used in teaching. Keywords: Logarithm, tangent, quadrature, fluxion, fluent, calculus

Numerické řešení inverzních integrálních rovnic matematického modelování ve výzkumu biopaliv
Bílková, Zuzana ; Hnětynková, Iveta (advisor) ; Kofroň, Josef (referee)
Název práce: Numerické řešení inverzních integrálních rovnic matema- tického modelování ve výzkumu biopaliv Autor: Zuzana Bílková Katedra / Ústav: Katedra numerické matematiky Vedoucí bakalářské práce: RNDr. Iveta Hnětynková, Ph.D., Katedra nu- merické matematiky MFF UK Abstrakt: Cílem této bakalářské práce je numerické řešení Fredholmových integrálních rovnic prvního řádu, které se vyskytují ve výzkumu biopaliv. Práce se zaměřuje na studium Lagrangových interpolačních kvadraturních formulí. Uvažujeme lichoběžníkové a Simpsonovo pravidlo s využitím ekvidistantního a logaritmického dělení. Cílem práce je srovnání těchto pravidel a nalezení nej- vhodnější metody. Práce se dále zabývá určením minimálního počtu naměře- ných dat tak, abychom dosáhli dané přesnosti. Poznatky jsou demonstrovány na numerických experimentech se simulovanými daty. Klíčová slova: inverzní integrální rovnice, kvadratura, konvergence, odhad chyby 1
