Mechanical design of mobile camera system via electric drive
Bosák, Dalibor ; Brandejs, Jan (referee) ; Paloušek, David (advisor)
This bachelor thesis deals with an overview of accessories for a camera movement and mechanical design of a mobile camera crane via electric drive. In the construction part of the thesis are primarily brought conception designs of a camera crane including stress analysis in each places of the crane and then the proposal itself according to the chosen concept. There are shown solutions of individual parts of the camera crane with their description and views. In the end of the thesis are resumed the advantages of the design and economical analysis including the prices of each components and the whole crane.

Small snow cutters
Ráheľ, Dušan ; Prokeš, František (referee) ; Brandejs, Jan (advisor)
The bachelor thesis deals with the subject of snowblowers. It describes their origin, evolution a current applications. It presents development and technical details of all snowblower sizes, ranging from smallest ones, driven manually by operating personal, to the largest, attached to the trains. The work explains modern hybrid snowblower powertrain. The combination of gasoline and electric engine proves to achieve substantial reduction of fuel consumption at unaffected efficacy of snow removal. The second part of work deals with our proposed novel method of snow removal, which employs its volume compression. A series of experiments were done in order to establish the relation between the exerted force and resulted compression of snow of various initial mass density. We have found that pressure smaller than 0,5 MPa is capable in average to reduce the snow volume to 45% of the initial value.

Level scraping systems of settlement tanks
Rusník, Tomáš ; Hort, Filip (referee) ; Brandejs, Jan (advisor)
Main topic of this bachelor thesis is analyse of settlement tanks scraping equipements in sewage plants. Settlement tank at the wastewater treatment plant is part of the so-called bio-lines, which is used for the separation of activated sludge from waste water. Activated sludge settles in the settling zone. Part of the sludge flotates to the surface of the tank, usually in the space between the inflow cylinder and overflow edge, respectively. This sludge, biological or chemical origin, may, at the massive occurrence, outflow to the recipient and causes worse quality of the effluent. The sludge is therefore necessary to remove from surface of the settlement tank. Some of the different systems of sludge collection have been developer during last decades. The equipments and their function are descriped in my work.
