Eliminator of dental calculus
Šobich, Adam ; Sekora, Jiří (referee) ; Rozman, Jiří (advisor)
Bachelor’s thesis is focused on system design of eliminator of dental calculus operating at a frequency of 27 kHz and reaching the intensity of ultrasound on the applicator tip to 5 W/cm2. The work analyzes problems of dental calculus, principle of ultrasonic waves and the physical phenomena occurring in the environment, which it passes. Another part of the work describes the creation of waves using ultrasonic transducer and the amplification of ultrasound in the waveguide. Practical part of work is presented by functional diagram, which describes the sequence and function of the main parts of the device. The Bachelor’s thesis presents individual steps for design of applicator and the circuit for eliminator of dental calculus, including calculations and diagrams. The resulting circuit is experimentally verified and supplemented with draft of the printed circuit board.

Využití samojízdných pracovních strojů v technologiích rostlinné výroby
Svoboda, Michal
This thesis is giving to the reader the overview about the self-propelled machines, which are working in the crop production. The first part of my work is regarding the basic division and description of the basic functional items, which are same for all machines. The second part is focusing to describe the functional parts of the individual types of the self-propelled machines and their adapters.At the end is the evaluation of the collected information regarding the CLAAS Xerion 4000 Saddle Trac with the KAWECO slurry tank.

Samojízdné mobilní prostředky v rostlinné výrobě
Řihák, Pavel
Bachelor´s thesis with the title Self-Propelled mobile machine in the arable fading focuses on the total summary of Self-Propelled mobile machine in the arable farming, which is most occurred in the agriculture. First part is focused on the basic division the most used Self-Propelled mobile machine in the arable fading including theirmain com-ponents and working organ. Every group self-propelled machnieis completed with ma-chnie from the selected producer. They occupy with development and production of self-propelled machine. This part is focused on construction and utilization modular powerunits, too. The second part is focused on the tehcnical-economic comparison se-lected self-propelled machine with tractor´s tools. These chapterin cludes self-propelled reapingpress Krone BIG M I and carried mower triple combination Kuhn FC.
