The Cross in Changing of Times and its Significance in Ancient Society
Roule, Radek ; Lášek, Jan Blahoslav (advisor) ; Weis, Martin (referee) ; Royt, Jan (referee)
The Cross in Changing of Times and its Significance in Ancient Society The cross is the most widespread symbol appearing worldwide right from the prehistoric times. Though being formed of a very simple shape of two intersecting lines the significance is far reaching. This dissertation looks at the cross both as a sign pointing beyond itself and concentrates on the diversity of its visual appearance. It tries to trace back the possible factors preceding Antiquity influencing the formation of the actual shape in that particular period of history. Although for most part the cross is understood in its connection with the Crucifixion of Christ its history is far more complex beginning in pre-Christian era. The biblical texts present more or less mere allusions of the cross itself. Seen typologically the cross may be understood as the element connecting both Old and New Testament creating a sort of a bridge between them. The careful analysis of the Early Christian documents brings several terms used for the same reality. The most significant are - σταυρός with the Latin equivalent crux and ξύλου (wood) with the Latin equivalent lignum. Later on these give a way to a more general term of σημεῖον (sign) and finally to a symbolic expression "σύμβολον σωτηρίας" (sign-symbol of salvation). The early Christian writers...

Design of a photovoltaic power plant for a family house near Jihlava
Dvořák, Vít ; Maule, Petr (referee) ; Vaněk, Jiří (advisor)
This diploma thesis deals with the design of a photovoltaic solar power station for a specific family house in the Jihlava region. The aim of the work was to get acquainted with technologies about the production of solar systems, evaluate the market in the Czech Republic and create a design of photovoltaic solar power station. Three designs of power stations were created with the help of the PV * SOL design system. Each design uses different photovoltaic cell technology. The result of each power station design is a complete finished project, which is based on many factors such as the efficiency of the entire system in a certain location, financial analysis, return on investment and more. In addition, these projects meet the conditions for the preparation of the subsidy program Nová zelená úsporám. At the end of the work, all three designed power stations are evaluated and with the help of multicriteria analysis, the best and most advantageous power station design for the given locality is determined. In the end, the idea of further development of the project is presented.

Renewable energy sources in CR
Kozumplík, Ondřej ; Škvařil, Jan (referee) ; Fiedler, Jan (advisor)
The content of bachelor study is the technical recherche of the renewable resources of energy in the Czech republic. It appears here the principal, use, potential and advantages and disadvantages of each type of renewable resources - water, wind and biomass. Then the use of solar energy for photovoltaic conversion to electrical energy is described in detail. At the end of this study is described one of the many recently build photovoltaic power stations in the South Moravia territory, the solar power station in Bzenec.

no noon on
Janechová, Lucia ; Houser, Milan (referee) ; Štindlová, Marie (advisor)
The thesis focuses on the theme of sun. We perceive the sun in many different ways according to its position on the sky, to where we are located or simply depending on our current mood. In paintings and objects I look for ways to capture it's visual form or the imprints of feelings it's capable of creating. For that I use spiky or round branch-like shapes as the variations of the sun rays, in the centre of paintings is usually a circle. I combine acrylics and oil with dry pastel, which enable more relaxed and free strokes. In effort to expand the scale of medium I included materials like copper or concrete in my work. The series is therefore finished with relief almost-objects and a copper “gate” the sun figuratively passes through at noon.

Alternative Energy Resources for Family House
Němec, David ; Brázdil, Marian (referee) ; Špiláček, Michal (advisor)
This bachelor thesis is focused at an issue of thermal energy supply for family houses from renewable resources. The aim of this thesis is to provide a summary of possible thermal energy supplies from renewable resources (solar collectors, heat pumps). After that follows a draft and economic evaluation of these systems for individual sources of thermal energy. In introductory section a solar energy is described. It is a significant part of renewable energy. This part is followed by review with description, composition and principle of individual types of solar collectors and heat pumps. Next part is focused on draft of these systems. Conclusion is then dedicated to energy evaluation of individual designed systems.

Using of Renewable Energy Sources for Family House Supply
Varmuža, Jan ; Macháček, Jan (referee) ; Toman, Petr (advisor)
This work is concerned to analysis and evaluation of present recoverable energy resources and position EU to them. In study is provided comparison of recoverable resources (biomass, water, wind, environment energy, and sun). The details are noted for all single cases. As the next addition are included various techniques „how to obtain and convert them“. In study are also noted which necessary equipments must be used and their proper location. In practical part is done comparison of barrier-layer photocell from polycrystalline and monocrystalline silicon and water insulating foil „EVALON SOLAR“. For comparison was taken only produced energy. Next step was financial analysis of each single system and comparison with pay-off in case that invested sum (actual price) was placed to bank under time deposit and share capital fund. During analysis of financial evaluation was found, that more suitable is system from polycrystalline silicon. Because of investors main condition is financial aspect, so for realization will be recommended system from polycrystalline silicon.
