Alternative solution and strength check of mechanical screens
Sommer, Matěj ; Malach, František (referee) ; Malášek, Jiří (advisor)
This master’s thesis deals with a new design of bar screens. The goal was to come up with an alternative design to already existing device by INKOS a. s. In the first part, there is a summary of various machines working in similiar conditions. The insights gained by this research influenced the design of the new device. It utilizes well proven solutions from previous projects, but some of these were reworked and a few new functions were added. Second part of the thesis describes the analytical solutions, which were used to determine the forces in the assembly during the operation of the device. Based on the results of these calculations, a strength analysis of important components was performed using the finite element method. The result of this thesis is the design and optimization of new bar screens, including engineering drawings and tools for its further development.

Wastewater pretreatment at sewerage network
Doskočilová, Denisa ; Sousedík, Milan (referee) ; Hlavínek, Petr (advisor)
ABSTARCT The aim of this thesis is to treat the problem of wastewater pretreatment on the sewer network with a focus on storm water overflow and their impact on waterways with regard to The Methodological Manual for Assessment of storm water overflow within uniform sewerage systems in urban areas. This work describes the legislation relating to storm water overflow and includes comparison with other countries. Furthermore, there is processed the outline of objects and equipment which can be used for wastewater pre-treatment in the sewer network. In the practical part of the thesis there is designed a new solution for the mobile spillway edge of the storm water overflow OK2A, which is located within the sewer network in Brno. In the practical part of the paper there is depicted the project documentation of newly designed equipment and objects. Water management companies, design offices, students and the general public can use this thesis as an inspiration.

A design of punching tool
Bastl, Dominik ; Omes, Jiří (referee) ; Tůma, Jiří (advisor)
This bachelor thesis deals with the design of a special punching tool for a bending machine. The aim is to design a punching tool which, thanks to its compatibility with an existing bending machine, would allow punching and bending of square tubes in one profile clamping, thus streamlining the entire production compared to the existing production process.

The measurement of melanopic quantities in indoor spaces with the luminance analyser LDA - LumiDISP
Siegel, Josef ; Baxant, Petr (referee) ; Motyčka, Martin (advisor)
This thesis focuses on measuring melanopic quantities in indoor spaces and their impact on individuals and their circadian rhythms. Melanopic quantities are specific parameters of light that influence biological responses and physiological processes in our bodies. To measure these quantities, a photometric analyzer is utilized, enabling the quantification of spectral components of light. It also evaluates the melanopic contributions of various lighting sources, such as LED fixtures, incandescent bulbs, or natural daylight.
