Condensing technology and flue gas
Müller, Jan ; Topič, Jan (referee) ; Počinková, Marcela (advisor)
This thesis is developed as a proposal for heating for a primary school and kindergarten in the region of Brno-countryside. For the insulated building, a combination of heating and air-conditioning is proposed. The concept is designed so that the air-conditioning preheats the exterior air and the heating system warms the incoming air to a comfortable temperature. For the required thermal performance, sources of heat (for gas and pellets) and a layout solution for the boiler room is designed. Drainage of combustion products is proposed for both solutions. The project solution is per the extent of the construction permit. The theoretical part is linked with the practical part through the condensation boilers, their function and division, and drainage of combustion products. The experiment for the given topic was conducted on the drainage of combustion products. The pressure loss of the reverse knob was determined in relation to the flow rate of air in the condensation boilers as this loss is essential in assessing the drainage of combustion products.

The assessment of the capacity of bridge profiles on the Bobrava river
Bezděk, Josef ; Roubcová, Radka (referee) ; Milerski, Rudolf (advisor)
This diploma thesis “The Assessment of the Capacity of Bridge Profiles on the Bobrava River” focuses on making calculations of a system of bridges by using HEC-RAS PC software. This thesis assesses the capacity of bridges and applies knowledge of model research to design increase the capacity. A model of a stream on Bobrava River will be created. Furthermore, modifications of a river bed and bridge profiles will be realized for safe conversion Q100 by these constructions. Subsequently, a model of the modified stream n Bobrava River will be made. Lengthways profiles of water surface, table and graphic outputs from HEC-RAS PC software and modified designs will be output.

New trends in the field of stone mastic asphalts
Pfeiferová, Magdaléna ; Varaus, Michal (advisor)
The work consists of two parts. The first part is focused on the determination of an anti-skid properties of the test section on Vídenská street. The anti-skid properties will be measured using a pendulum tester and macrotexture will be set at the same time. Microtexture will be measured using a volumetric patch technique. In the second part we will try to gain an initial experience with design and testing of a low noise stone mastic asphalt. We will set basic characteristics and at the same time compare with a standard stone mastic asphalt. For the comparison two various bituminous binders are used. The water sensitivity, resistance against rutting and stiffness moduli are compared.

Advanced methods of surface topography evaluation
Metelková, Jitka ; Prokop, Jaroslav (referee) ; Píška, Miroslav (advisor)
This paper provides an overview of contemporary methods for evaluation of the part surface, nowadays measurement devices and evaluated parameters. The main part of the paper is devoted to advanced methods of surface topography evaluations including the application of the new non-contact measurement technique Alicona G4. The experimental part deals mainly with a study of surface texture parameters of the machined aluminium alloy AlCu4MgSi when face turning. It concerns mostly a study of the tool feed rate influence (the uncoated insert GIPA-6.00-3.00, ISO 513 N05-N25, Iscar) on selected profile and surface parameters, including comparison of measurement results achieved by the contact (Form Talysurf Intra 50, Taylor Hobson) and non-contact method (IFM G4, Alicona).

Functional surfaces and surface texture
Novák, Jiří ; Brandejs, Jan (referee) ; Svoboda, Pavel (advisor)
The aim of this bachelor publication was an elaboration of professional recherche about geometric product specification (GPS). My publication contains the comparison of the foregone and current norms, which include parameters surface texture and notation surface texture, relation of surface texture and surface function, incoming development trends and needful supplements.

Možnosti hodnocení textury povrchu frézovaných obrobků ze dřeva
Machučová, Monika
In my thesis I deal with method for evaluation texture of 2D profile and 3D surface, which were applied to real beech wood samples. For the experiment was used contactless sensor of confocal device Talysurf CLI 1000. For evaluation of measured values were used softwares Talymap Platinum (3D) and Talyporfile Platinum (2D), these softwares allowed compare charatceristics of 2D and 3D surface roughness of milled beech samplex under certain humidity condition.
