Mind Pollution
Krausová, Zuzana ; Knoflíček, Tomáš (referee) ; Klodová, Lenka (advisor)
In my work I deal with parallel sounds of engine and beast. I analyzed the sounds of different beasts and searched for those that are as close as the sounds of the engine. As a representative of engine sound, I chose a motorbike, because the character of the beast corresponds with its character. I decided to turn the sound of the engine to the sounds of the beast, so that they responded to the rotation of the gas and whimpered while driving. I use the sounds of a tiger, alligator, cheetah, leopard, lion, and cats. Part of the thesis is interventions in the public space using a sound-engineered motorcycle.

Assessment of Ochozsky Brook Status
Vaculíková, Klára ; Tůma, RNDr Antonín (referee) ; Malá, Jitka (advisor)
Bachelor's thesis deals with an evaluation of Ochozský stream in the village Březina in Moravian Karst. There was done a survey of a ground and the stream surroundings. There was also gained information from the Municipal office on technical adjustment of the stream, sewer network, waste water treatment plants and polluters of Ochozský stream. Two measurements of physicochemical parameters and sampling were carried out at six sampling points in autumn 2017 and in spring 2018. Flow rate was measured at three sampling points. Conductivity, pH, temperature, oxidation-reduction potential, concentration of dissolved oxygen and saturation with oxygen were measured in situ. COD, BOD, total phosphorus, ammonia, nitrites, nitrates and Kjeldahl nitrogen were determined in water samples in the laboratory. Organic nitrogen and total nitrogen were calculated. The results were evaluated with a respect of Government Decree No. 401/2015 Coll. There was also provided a hydromorphology assessment of Ochozský stream using methodology Stream Visual Assessment. A land use of the offshore stream strip was mapped.

Dust separators for small power boilers
Szweda, Martin ; Baláš, Marek (referee) ; Milčák, Pavel (advisor)
This thesis is divided into two parts. The first part of this thesis contains research on pollutants, separators and its legislation, while this part is focused on dust particles and their separation behavior. This is followed by a search on the different types of separators that can be used for small power boilers. The second part is followed by an experimental part, where the practical efficiency of the given separator is verified and then the measured values are compared and the result is evaluated. The results are used to determine whether the separator used is suitable for the separation of biomass for low-power boilers.

Mathematical models of retention object of urban drainage
Pavlík, Ondřej ; Stanko,, Ing Štefan (referee) ; Pollert,, Jaroslav (referee) ; Prax, Petr (advisor)
This work deals with the use of 3D mathematical models of fluid in water management practice. Using 3D mathematical model was assessed retention tank Jeneweinova, which is situated on a sewer network of the city of Brno and is an important object of urban drainage. Retention basin designed to keep overflow from CSO chambers to Svratka and Svitavský náhon during storm events. Retention tank Jeneweinova is suitable for the assessment, because tank was designed bassed the Master Plan drainage of Brno using 1D mathematical model. Another factor was the physical model, which was build in LVV Vin FAST BUT. And finally, near the retention tank will be installed measurement on the sewerage network, which will be able to verify the results whitch has been predicted in this work. Mathematical model of retention tanks Jeneweinova was build in software FLOW-3D. FLOW-3D is a general purpose CFD (Computational Fluid Dynamics) software for flow of fluid in steady and unsteady mode and uses computational techniques to solve the equations of motion of fluids. This software is mainly used for the calculation of hydraulic fluids, gas flow and heat transfer simulations. Results from 3D mathematical model has been compared with the values in the physical and 1D mathematical model.
