Ventilation of the archive
Hudeček, František ; Fišer, Jan (referee) ; Hejčík, Jiří (advisor)
Ventilation systems for depositories have certain specifics. Their main objective is to provide safe environment for preserving unique cultural or other valuable objects that are being stored for extensive time periods. The economical aspect of the operation should be taken into ac-count and the ventilation system adjusted accordingly. This project also incorporates ventila-tion of secondary areas. Ventilation system is subsequently assessed in terms of indoor air quality (CFD simulation) and energetic requirements (program TRNSYS). Air quality in depositories is evaluated using age of air parameter. The qualitative and quanti-tative outcomes are obtained. Possible measures are then suggested to improve the air quality. The objective of energy simulation is to evaluate overall energy required for a year of opera-tion of main air handling units. In addition, estimation of energy requirements for heating and cooling are made for the whole building. The results are compared and more simulations are carried out in order to lower overall energy consumption.

European regulation of virtual currencies, its shortcomings and future development.
Fišer, Jan ; Vondráčková, Aneta (advisor) ; Kunertová, Tereza (referee)
European regulation of virtual currencies, its shortcomings and future development Abstract This thesis is focused on the European regulation of virtual currencies, meaning the current Union legal regulation of this phenomenon including further European Union institutions' activities in the area. The aim of the thesis is to introduce the existing approach towards virtual currencies as well as to find some of the shortcomings and to outline the future development of European regulation of virtual currencies. As a part of this thesis, relevant activities associated with distributed ledger technology as a technology related to virtual currencies will be introduced. To achieve the mentioned, the thesis analyzes mainly legislative and non-legislative sources issued by competent institutions of the European Union, equally important are the jurisprudential texts from the area of virtual currencies and related fields. The thesis is divided into five chapters which are further divided into topical subchapters. Each of the chapters includes partial identification of shortcomings and presents the future development in the area. The introductory chapter addresses the introduction of virtual currencies as such and in the context of financial law. Further, technological bases of virtual currencies are described, namely...

This diploma thesis deals with design of ventilation and heating of bungalow single-storey house. The work is divided into three parts. In the first part is presented the design of the house with calculation of heat losses. The second part deals with the design, calculations and regulation of the heating of the house. In the third part there is designed a system of forced ventilation for the house.
Investigation of impact of radiant heating and cooling on car driver thermal comfort
Pavlík, Vojtěch ; Tuhovčák, Ján (referee) ; Fišer, Jan (advisor)
This diploma thesis is focused on the matter of radiation heating, thermal comfort maintenance and setting optimal operation parameters for heating system equipped with radiation panels. The research section summarizes the effects most important for thermal comfort, methods of its determination, heat exchange distribution between the human body and its environment, and technical possibilities of heating car interiors. The central points of this work are the simulation of car interiors heated with radiation panels and the evaluation of thermal comfort with a virtual mannequin. Thermal state was determined via the equivalent temperature and thermal comfort zones diagram (method by O.H. Nilsson). Forty-two simulated scenarios led us to conclude that thermal comfort is not possible to obtain with panels exuding a maximum temperature of 43 °C and the combination of several heat sources is required. Nevertheless radiation heating considerably contributes to energy savings without the loss of thermal comfort in assessed car.
Reducing energy dependence of block of flats
Bouchal, Patrik ; Fišer, Jan (referee) ; Hejčík, Jiří (advisor)
Bachelor thesis is focused on the assessment of energy self-sufficiency of block of flats. The introductory part deals with the block of flats itself. In the second part, it is thoroughly discussed whether there is sufficient amount of rainwater falling on the roof of the huse and it’s further use. The third part deals with the use of photovoltaic panels.

Proving by finite automata
Fišer, Jan ; Holub, Štěpán (advisor) ; Chvalovský, Karel (referee)
In 2016, Hamoon Mousavi published Walnut which is a program that implements automated theorem proving of propositions about automatic sequences. The main purpose of this thesis was to show the theoretical functi- onality of Walnut on the basis of the relation between automatic sequences and Presburger (resp. B¨uchi) arithmetic that is a decidable theory. Another goal was to describe adequately how the decision procedure of Walnut really works, and finally, to show the practical use of Walnut on several particular problems. One of these particular problems that are solved in the thesis is computation of the critical exponent of the Rudin-Shapiro sequence - this exercise was presented as an open problem in a book of 2003 (however, this exercise does not belong among open problems any more since Shallit proved in 2011 that the critical exponent is computable for all automatic sequences.) The last chapter itself can be also used as a brief manual for newcomers to Walnut that want to use this program for their own applications. 1
Stony routes in the Broumov walls and their importance for identity formation of landscape and region
Fišer, Jan ; Kučera, Zdeněk (advisor) ; Tůmová, Martina (referee)
The thesis deals with the analysis of current condition and heritage of old stony routes in the Broumov walls. These routes were built from variously sized sandstone blocks of local origin. The routes are specific for the area of interest and they have their long history. The aim of the thesis is, with the example of the Broumov walls, to discuss the importance of the old routes as specific historical landscape structures and local heritage for shaping of the identity of the region and its specific character. Regional identity, heritage and historical landscape structures belong to key concepts introduced in the theoretical part. Significance of the routes as a specific kind of the heritage and an integral part of local cultural landscape is discussed. In the empirical part of the thesis, results of a partial inventory of stony routes in the Broumov walls, which have been done during research, are introduced. The result is shown in attached maps. The inventory was focused on classification of the routes by degree of conservation of the original character and by ways of use today. The thesis also deals with the research on perception of route heritage and contemporary ways of its use by local authorities. Possibilities for protection and future reconstruction of the stony routes are searched. The...
Ways to influence amateur's athletes postural stability
Fišer, Jan ; Zahálka, František (advisor) ; Nováková, Tereza (referee)
Title Ways to influence amateur s athletes postural stability Objectives The aim of this study is to describe the selected parameters of body composition and postural stability of the amateur s athletes (floorball players) group and to assess the efficiency of short-term intervention exercise based on senzomotor stimulation, acral coactivation therapy and plyometrics. Methods This work is a descriptive work, one part of it is the intervention. Two groups of amateur s athletes (floorball players) were examined during the study - intervention group(n = 16, average height = 178,23 cm (std 7,18), average weight = 80,04 (std 11,53), average age = 25,15 years (std3,31 )) and control group(n = 8, ave- rage height = 181,48 cm (std 5,59), average weight = 82,29 kg (std 11,20), average age = 27,07 let (2,68)). Each participant underwent the entrance measurement both on Footscan to evaluate the level of postural stability by selected parameters and on InBody 3.0 a Tanita to evaluate the level of body composition by selected parame- ters. Then the intervention group took part in the intervention exercise. After the six week intervention period underwent both groups the second measurement. The results of both measurements were evaluated, compared and statistically analyzed. Results The results showed great...
