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.

Mapping of lubricating film thickness of human big joints replacements
Bosák, Dalibor ; Hartl, Martin (referee) ; Vrbka, Martin (advisor)
This master’s thesis describes mechanism of lubricating film forming and its thickness in contact of a metal hip joint ball and a glass disc with chromium layer with presence of bovine serum as substitute of synovial fluid occured in a natural joint. Lubricating film thickness is evaluated by a thin film colorimetric interferometry, results are ploted at graphs representing dependence of lubricating film thickness on experiment duration or on mutual speed of articulating surfaces. There is described the influence of concentration of bovine serum and different kinematic conditions on lubricating film forming. From observed interferograms is apparent the adsorption of proteins to glass disc and femoral head surfaces, denaturation and formation of protein aggregations affecting the residual lubricating film thickness.
