NEW ON THE „OLD“ – Brno, Bratislavská - Stará Corner
Mach, Jiří ; Antl, Roman (referee) ; Ruller, Ivan (advisor)
Designed objects are located in the centre of Brno, corner of Bratislavská and Stará streets. New buildings close gap in the corner and create full-fledged square, its need was determined by some analysis made in our fakulty. The buildings thus define a small square at Bratislavská street and encircle inner court, in which are designed other two houses. The square creates free space in front of Radost theater and improves public space of the street. The court has a semiprivate character – it is joined with the square by a wide passage. In the court is a park, in parter is a civic center. The court can be used by local inhabitants as well as by children from Radost theater (puppet theater for children). All the houses have a facade made of a coloured concrete. Soft differences between colour divide individual parts. The houses have organic facade with randomly placed windows. However the windows are placed in a raster, which is repeated in each floor. Randomness is accompanied with order. In parter of all buildings are civic amenities, on floors are small flats and office spaces. Under buildings are two floors with garage. In complex will live probably students and young families. Young people will support progress of this district. Civic amenities and new public space will support social life. In parter are leasable spaces, where can be shops, repairers or art and craft workshops. They will help to provide jobs for local people.

Optimization of the siphon swirl turbine draft tube
Mach, Jiří ; Haluza, Miloslav (referee) ; Rudolf, Pavel (advisor)
The goal of this diploma thesis is to design a new shape of the draft tube, which will be easier to manufacture while maintaining good strength and hydraulic properties. First part of this thesis is devoted to the formulation of the problem, description of the swirl turbine, principle of operation, the basic variants of arrangement, also the function of the draft tube, its efficiency and other formulas. In the second part of this thesis is a CFD and strength analysis of the original design, also a new design is proposed and the possibility of optimization using ANSYS Fluent Adjoint solver.

SIEMENS LOGO! RCE - posibility to use in informatics learning Attachments and network functions.
MACH, Jiří
Aim of this bachelor thesis is to use logical microsystem Siemens LOGO! RCE for temperature measurement and due to that LOGO! from version 7 contains ethernet modul, I'll be using telemetry, thus measurement for long distances and remote data transfer. Siemens LOGO! RCE presents univerzal logical modul. It offers sollutions for simple swithcing and application management in industry (eg. ventilation systems, barriers, water pumps, compressors etc.), it can however be advangtageously used also in the infrastructure (eg. lightning control, blinds, showcases, for irrigation etc.). Further it is suitable for installation in switchboards and mechanical devices. This bachelor thesis will have practical and theoretical part. In theoretical part I'll summarize available technologies for automation control and I'll analyze the options of Siemens LOGO! RCE and its use, I'll focus on the description and functionality of software LOGO!Soft Comfort V7.0. In practical part I'll create program for temperature measurement using two temperature sensors and theire comparing.

Direct effect of eutrophication on microbial processes in wet meadows soils with accent on nitrogen cycle
MACH, Jiří
Increased nutrient input to wet meadows ecosystems often leads to eutrophication. This thesis observes direct effect of fertilization on microbial processes and transformations of nitrogen in three different types of soils. A laboratory experiment consisted in one-shot nutrient addition (fertilizer NPK). Changes in C, N, P microbial biomass, changes in transformations of nitrogen (nitrification, mineralization N, asimilation N, denitrification) and changes in mineralization C (soil respiration) were studied during 21 days.
