Measuring system for analysis of pressure relations in spray lubrication device
Popelka, Michal ; Vaverka, Michal (referee) ; Nevrlý, Josef (advisor)
This thesis deals with the selection and design layout of the measuring system for the analysis of pressure and flow conditions in the lubricating system and a particular pressure and flow sensors. Sensors were selected according to suitability for use in these conditions of measurements (pressure, flow, etc.). Work also includes the review and selection of data bus for converting the output signal from the sensor to the evaluation unit (computer). It also includes selection of the measurement software to analyze the values arriving from the sensors into the measurement computer, find the optimal conditions for lubrication of wheel flanges of rolling stock.

A family house with an establishment
Popelka, Michal ; Pilný, Ondřej (referee) ; Berková, Petra (advisor)
This bachelor thesis is focused on design of family house with an establishment serving as financial consultancy. The object is located in cadastral area of Strání and has a partial basement with two above-ground floors. The house is established for four member family. External walls of the basement are bulit of permanent formwork. External walls of above-ground walls are bulit of clay blocks Porotherm 30 Profi with contact thermal insulation system ETICS. Horizontal load-bearing structures are formed by prefabricated rib-and-filler floor system MIAKO. Staircase is designed as two times bent slab. Part of the object is roofed with a warm flat roof, the other part with roof truss with roof slope of 35°.

The study of transition between fully flooded and starved regimes in EHL Contact
Popelka, Michal ; Čermák, Jan (referee) ; Svoboda, Petr (advisor)
The diploma thesis deals with The study of transition between fully flooded and starved regimes in EHL Contact. The work is focused on problems of starved contact and surface texturing of rubbing surfaces. Surface texturing of rubbing surfaces is one of the adjustments that cause in a sense improved lubricity and reduce friction and wear. The aim of this study is to compare numerical models with real experimental results measured on the Experimental apparatus.
