The thesis deals with the design and development of control algorithms and visualization system for controlling of eccentric press and its implementation into the press line. As a control system a SIMATIC s7-300 is used and for visualization the touch panel MP370 is implemented. The first part of the thesis describes a technology of the press line. This is followed by the design of hardware equipment and specification of control units. The thesis also provides insight into the creation of PLC program and explanation of specific functions. Finally, the development of visualization of the machine and description of application windows are demonstrated in the present work.

Behaviour of Objects in Structured Light Fields and Low Pressures
Flajšmanová, Jana ; Čižmár, Tomáš (referee) ; Marago, Onofrio (referee) ; Zemánek, Pavel (advisor)
Studium chování opticky zachycených částic nám umožňuje porozumět základním fyzikálním jevům plynoucím z interakce světla a hmoty. Předkládaná práce podává vysvětlení zesílení tažné síly působící na opticky svázané částice ve strukturovaném světelném poli, tzv. tažném svazku. Ukazujeme, že pohyb dvou opticky svázaných objektů v tažném svazku je silně závislý na jejich vzájemné vzdálenosti a prostorové orientaci, což rozšiřuje možnosti manipulace hmoty pomocí světla. Následně se práce zaměřuje na levitaci opticky zachycených částic ve vakuu. Představujeme novou metodologii na charakterizaci vlastností slabě nelinearního Duffingova oscilátoru reprezentovaného opticky levitující částicí. Metoda je založena na průměrování trajektorií s určitou počáteční pozicí ve fázovém prostoru sestávajícím z polohy a rychlosti částice a poskytuje informaci o parametrech oscilátoru přímo ze zaznamenaného pohybu. Náš inovativní postup je srovnán s běžně užívanou metodou založenou na analýze spektrální hustoty polohy částice a za využití numerických simulací ukazujeme její použitelnost i v nízkých tlacích, kde nelinearita hraje významnou roli.
Remote Laser Induced Breakdown Spectroscopy (LIBS)
Novotný, Jan ; Zemánek, Pavel (referee) ; Pína,, Ladislav (referee) ; Kaiser, Jozef (advisor)
The dissertation thesis deals with the development of the Laser-Induced Breakdown Spectroscopy (LIBS) setup in the modification for the mobile remote material analysis (so called rLIBS). The experimental device is developed at the Institute of Physical Engineering, Faculty of Mechanical Engineering (FME), Brno University of Technology (BUT). Such a modification is possible due to the core principles of LIBS technique, i.e. using a laser for a sample excitation and plasma radiation for spectral analysis. The thesis is focused on the variation called Stand-Off LIBS with the target analyte in the distance of 6 meters. In this case the laser pulse and the plasma radiation are transmitted through the local environment (usually the air) and the direct device-to-sample visibility is expected. The motivation for this development is to avoid traditional processes of sample collection, preparation and transport that are time-consuming, expensive and sometimes even hard to realize. Stand-Off LIBS allows bringing all the LIBS technique benefits from the laboratory to the field, where fast, in-situ analysis can be carried out. The first part of the thesis focuses on the history and principles of the Atomic Emission Spectroscopy (AES), as it is the main principle of LIBS technique. The second part describes the history, theory, instrumentation and applications of LIBS as a modern analytical tool. This part also introduces the remote mobile modification – rLIBS, as well as the current state of knowledge and the state of the development in LIBS laboratories worldwide. The third part describes the individual stages of the rLIBS development at the Institute of Physical Engineering, FME BUT. This chapter details the focusing optics design, building of the collection optics, design and construction of the detection unit, motorized stage and mobile track. This section contains also the results of the test spectroscopy measurements and movement ability measurements.
Control software for a model of pills filling machines
Střižík, Jakub ; Zemánek, Pavel (referee) ; Pásek, Jan (advisor)
The bachelor thesis deals with the creating of distributed control software for two pills filling machines. Pills filling machines contain of six drains and are controlled by programmable logic controller Simatic S7-300. At one time they can to fill the six packages and each of them can be set for different number of pills. Communication between individual devices is implemented in industrial Ethernet. The control is done through the filling machines and also through the visualization of one PC at control room. The operator can easily monitor and control the whole process of filling.

Childern´s Sanatorium Ostrov u Macochy
Zemánek, Pavel ; Vostrejž, Dušan (referee) ; Odvárka, Antonín (advisor)
The architectural study deals with the design of Childern´s sanatorium with speleotherapy in Ostrov u Macochy. Design works with the idea of connecting with the surrounding nature, responds to the slopping terrain and tries to fulfill a comprehensive construction program. A characteristic element is the use of natural material – wood within the curtaing walling, which defines the architectural expression of the building. Emphasis is placed on renewable energy sources.
