Office Building - Brno
Červinka, Tomáš ; Pilný, Ondřej (referee) ; Kalousek, Lubor (advisor)
The aim of the diploma thesis is to design a new office building with client operation. The building is designed with requirements for buildings with almost zero energy consumption. The project also includes a complete fire safety solution for the building and a certificate of the building's energy performance. The diploma thesis is processed in the form of documentation for execution of the project.

Heat recovery ventilation unit
Balák, Jan ; Fišer, Jan (referee) ; Hejčík, Jiří (advisor)
This bachelor thesis will inform readers about residental buildings ventilation posibilities, higyenical standarts of ventilation, sorting of heat recovery units used for heat recovery in residental buildings. Moreover, specific house will be choosen and its ventilation demands will be calculated. Than conveniend ventilation and heat recovery equipment will be search, because of optimalization of ventilation and heat losses.

Design of Multi-functional Component for Minibus
Kárych, Tomáš ; Křenek, Ladislav (referee) ; Sládek, Josef (advisor)
This work deals with the issue of ventilation by the rear window of the fifth door in minibuses converted into motorhomes. The goal is to design a component that extends the eye of the window lock of the fifth door and allows regulation of the ventilation gap while maintaining the functionality of the locking system. Furthermore, implementation of a multifunctional tool that will help in unexpected situations and will serve as an advertising and gift item. The solution must meet the criteria of manufacturability, functionality, aesthetics and feasibility in relation to the market size. The final product consists of a component, a multifunctional tool and a case that meets the initial goals and solved the problems that arose during the design. An aesthetically pleasing design was created with regard to small-scale production, sustainability and usability of the customer target group. The work discusses the process of an unconventional combination of products and a comprehensive solution to a very specific problem with a large number of smaller goals.

The impact of intervention breathing programme on breathing economy during increasing load
POUL, Daniel
Breathing is essential part of our life. Breathing exercise can help acquirement of proper breathing. Thanks to this process, sports performance can be improved. The aim of our work is to determine differences in values and compare results of spiroergometric parameters from testing on a bicycle ergometer in the laboratory of functional load diagnostics. We obtained the results by an entrance test and a final test tested after eight weeks. Between testing, selected individuals performed a respiratory intervention program. Nine performance university athletes, especially focused on football, got involved in our research. Data at the rest position and load were crucial. We focused on dynamic ventilation parameters such as tidal volume, respiratory rate, minute ventilation or oxygen consumption. In the output test, we also recorded changes in values in the respiratory segments, abdominal, thoracic and subclavian areas. We verified the results from the point of view of material and statistical significances. Both of these significances were evaluated in this thesis. The materially and statistically significant differences in the results of measurement were improved in the oxygen consumption by our probands. The studied probands were able to improve in various phases of load, for example, the material significance was detected at the respiratory rate during the load of three watts per kilogram. Ascertained results were not improved in all monitored parameters. The most significant changes were discovered in the three-watt load during the respiratory rate from 32,8 +- 7,2 to 30,9 +- 5,1 breaths per minute. Probands reduced oxygen consumption by 14.8 percent.

Wind-tunnel Modelling of Turbulent Flow Inside the Street Canyon
Kellnerová, Radka ; Jaňour, Zbyněk (advisor) ; Brechler, Josef (referee) ; Jonáš, Pavel (referee)
Turbulent flow inside a street canyon was investigated in an open circuit wind tunnel and in a blow-down wind channel. Two geometries were used for comparison purposes: buildings with pitched roofs and with flat roofs. Both generate the flow of a different category, so the induced ventilation regimes are fundamentally different. Quadrant, Fourier and Wavelet analysis, Proper Orthogonal Decomposition (POD) and vortex detection methods are used to identify coherent structures in the flow and establish their impact on the ventilation of pollution. Two types of the organised motions are detected: the compact areas of sweep and ejection with the scale comparable to the size of building and the small vortices generated in the shear layer behind the building roof. POD identifies the most dominant modes with high coherency in the flow and evaluates the relative contributions of each mode to the overall kinetic energy of turbulence. Rigorous analysis of the correctness of the physical interpretation for such a decomposition is carried out. Wavelet analysis is applied to the time-series of the POD expansion coefficients in order to reveal control mechanism of the dynamics of the modes. Vorticity, calculated from the original velocity data, is decomposed by POD as well. Finally, the correlation between the vorticity...

Hyperventilation in scuba diving
Blažek, Dušan ; Fiala, Miloš (advisor) ; Bažant, Filip (referee)
Title: Hyperventilation in diving Objectives: The main goal of this labour is to finde out, if hyperventilation and inhalation of high-percent oxygen has influence on sport effort in diving. Also outline possible danger and hazards in diving. Very important goal of this labour is to inform reader about diseases and shocks connected with diving, and first aid when they come actual. Methods: In this labour, I used analysis method of documents. It was mainly used literature sources related to human physiology and scuba diving. Results: From this labour results, that hyperventilation and inhalation of high procent oxygen rises achievment at free diving and may have positive influence in short route swimming. The rest of this labour has mainly informative character about physiology and dangers connected to diving. Labour can serve as informative material for beggining divers. Keywords: hypoxya, ventilating, oxygen, acidosis, tetany

Modelling of changes of the intracranial pressure (ICP) during physiological and pathological processes
Vaněk, Petr ; Otáhal, Jakub (advisor) ; Suchomel, Petr (referee) ; Sameš, Martin (referee)
The more we know about the circulation of CSF through ventricle system, brain parenchyma, subarachnoideal space and the development of intracranial pressure (ICP), the more we understand different pathologies and pathological processes of the central cervous system. The knowledge about the basic hydrodynamic charecteristics of craniospinal system is a key factor for understanding a wide range of pathological situations affecting CNS, these are for example intracranial hypertension, normal pressure hydrocephalus and syringomyelia. In the presented paper, we are presenting a newly developed measuring system Visionbrain that enables us to gain the biological data and consequently to analyse them. At the same time, the results of such measurements were used to specify the compertmental model of CSF circulation. The model devides craniospinal system into five divisions - two intracranial and three spinal. Such model is the third generation of this model and, compared to the older version, it includes two intracranial veins. Thanks to this stucture, the model enables us simultaneous modeling of heart and respiratory pulsations of CSF. Compared to the other published models, it also includes defined structure of spinal part. The model is derived using laws of conservation and it encompasses pressure...
