The development of fire-resistant repair mortars with fine-grained filler
Záruba, Jiří ; Gross,, Tomáš (referee) ; Bydžovský, Jiří (advisor)
The diploma thesis is focused on fire-resistant repair mortar with fine-grained filler. The aim of this work is the research and development of fine-grained Mortars resistant to high temperatures, which are characteristic at the beginning of the fire. The theoretical knowledge with subsequently realized laboratory verification was used. At-tention was paid to the masses based on the mixed binder comprising cement and blast furnace slag, respectively. high-temperature ash. Cellulose fibres were used as the dis-persed reinforcement. Two kinds of aggregate were assessed - fly ash agloporit and am-phibolite incl. combinations thereof. Laboratory tests were carried out via determination of basic material properties (density, strength, consistency, dimensional changes etc.) after exposure to extreme temperatures. A substantial part of the research was also study of different cooling conditions - slow and fast (water and air). Selected formulations were subjected to temperatures up to 1200 ° C. In the conclusion is selected several recipes that have been found to be optimal for continuing research on the basis of the results and findings.

Study of the development, trends and innovations in shotcrete technology
Záruba, Jiří ; Hela, Vlastimil (referee) ; Hubáček, Adam (advisor)
The Bachelor thesis is focused on the study of development, trends and innovations in shotcrete technology. The main target of this thesis is to summarize new procedures in shotcrete technology. Secondary targets include a description of basic properties of sprayed concrete, introducing new trends and technology in recent years. The next sub-goal is to propose experiment that will try new ways of testing shotcrete. Based on these secondary targets is possible to evaluate the current situation in shotcrete technology and fulfil the main objective of this thesis.

Calculation of induction machine cooling
Záruba, Jan ; Huzlík, Rostislav (referee) ; Janda, Marcel (advisor)
This thesis discusses in the first part of the theoretical concept of flow and cooling induction machine. His behavior , characteristics and possible variants of its calculation . Questions concerning losses from the engine, through the second cooling flow types and finally the calculation. The second part focuses on practical laboratory measurements on a real model. Furthermore, the evaluation of its results. The third part focuses on computer simulation and calculation. The third part is further divided into three phases , where in the first phase devoted to the calculation and simulation flow to the fan motor. In the second stage, the third part deals with the flow in the engine itself , and the third is described and simulated temperature analysis . In the final third phase are subsequently evaluated by computer simulations and compared with practical measurements . This comparison is based on the theory described from the beginning.

The Sunday Christ
Záruba - Pfeffermann, Josef ; Royt, Jan (advisor) ; Kubík, Viktor (referee) ; Klípa, Jan (referee)
The work is a monograph on the late medieval devotional image of Sunday Christ (Feiertagschristus, Christo della Domenica, Svjeta Nedelja, Christ du dimanche, Sváteční Kristus). The main aim of this research was to create a complete catalogue of all examples of the "Sunday Christ" image and explain its origins and development. Origins of this image are found in the various conceptions of the continual Christ's suffering for our sins. The author is using the recent bibliography on this image (Koman, Reiss, and Rigaux) but the concept of the development is based more on the definition by Gertrud Schiller. The origins are seen in the mystical images from the cloister environment.- Sponsus pierced by Sponsa, Mystical nailing, nailing with various tools, Arma Christi, fabrication of Arma Christi, and other motifs found especially in the art of female convents. The pastoral care of nuns was usually practiced by Dominicans and other preaching orders, which probably modified some of the images of perpetual passion for the use of laity. As a certain reflection of this contemplative phase we may consider the Casatanense Manuscript (Rome, MS 1404) and mystical visions of Archbishop John of Jenstein, (1379) which included an ecclesiastical image of Christ attacked by Christians. The mural paintings had been painted in...
