Manipulator of pack
Raba, Milan ; Čermák, Jan (referee) ; Brandejs, Jan (advisor)
This work is about construcion of a manipulator to be used in paper manufacturing. The manipulator is desinged to turn a package of cellulose placed on a roller conveyor. Turning of the package is necessary for unwrapping and cleaness control of cellulose. Design was made based on analytical calculation and was verified using computer simulation. Pneumatic valves and an electric motor were utilized in the manipulator. The manipulator operates automatically.

Effect of surface texturing on rolling contact fatigue of rubbing surfaces
Popelka, Jakub ; Čermák, Jan (referee) ; Křupka, Ivan (advisor)
Diploma thesis describes influence of directed modificated topography of frictional surfaces on fatigue wear non-conformal incurvate solids. It was created 3D parametric model of experimental test rig in modelling environment Autodesk Inventor. With the help of model was designed and carried reconstruction of experimental test rig so to possible obtain repeatable results under the sliding conditions of frictional surfaces. It enabled show influence of surface iregularities (dents) frictional surfaces on contact fatigue service life in conditions mixed lubrication regime and different values of slide to roll ratio.

Fractional differential equations and their applications
Kisela, Tomáš ; Tomášek, Petr (referee) ; Čermák, Jan (advisor)
Zlomkový kalkulus je matematická disciplína zabývající se vlastnostmi derivací a integrálů neceločíselných řádů (nazývaných zlomkové derivace a integrály, zkráceně diferintegrály) a metodami řešení diferenciálních rovnic obsahujících zlomkové derivace neznámé funkce (tzv. zlomkovými diferenciálními rovnicemi). V této práci představujeme standardní přístupy k definicím zlomkového kalkulu a důkazy některých základních vlastností diferintegrálů. Dále uvádíme krátký přehled metod řešení některých lineárních zlomkových diferenciálních rovnic a vymezujeme hranice jejich použitelnosti. Na závěr si všímáme některých fyzikálních aplikací zlomkového kalkulu.

Moisture sensor
Čermák, Jan ; Klusáček, Stanislav (referee) ; Beneš, Petr (advisor)
This bachelor work consider with question of measurement of air humidity. Here are the basic theorem, wich have relation to air humidity, and detailed description of methods, wich are used in air humidity sensors. After come note about qestion of measurement humidity in soild substance. Next theme is calibration of sensors. In the last part is describle the structure of electrical network with unificated readout., wich is dependent on surrounding relative air humidity. Obiter work contain practical measurement of humidity in industry and qestions about it.

Meaurement process automatization of deviations and stability of oscilators
Čermák, Jan ; Nováková Zachovalová, Věra (referee) ; Havlíková, Marie (advisor)
This Master´s thesis on a topic ,,Meaurement process automatization of deviations and stability of oscilators‘‘ describes methods for measuring the difference of time scales. Using this method, calculates the parameters of the oscillator, which is also describes in this work. Parameters of the oscillator means inning and stability. Describes is the procedure for calculating the uncertainties and their presentation in the final calibration sheet. This Master´s thesis also describes the practical measurement with this method in the Czech metrology institute in Brno. Measurement of the parameters of oscillator by the method of measurement of the difference of time scales is carried out automatically by computer. This Master´s thesis deals with the creation and development of new software and thus the automation of the entire task.
