Critical Factors of Implementation of Module APO to SAP System in the Chosen Manufacturing Company
Vetýška, Jan ; Skoupý, David (referee) ; Sodomka, Petr (advisor)
The thesis deals with the issue of the implementation of the corporate information system of the ERP category, specifically the introduction of the module of APO for SAP in the chosen manufacturing company. The work presents the theoretical fundamentals describing the basics of ERP along with available methodologies, the implementation of these systems. Also analyzes the frequent causes of delayed implementation projects and provides the basis for the search for the causes of the problems. In the next section it is made an overall analysis of the current state of the ERP system in the company. At the conclusion of this work are defined recommendations, which can be prevented critical factors and implementation could be completed according to the established timetable.

Determination of iodine in food
Malčíková, Hana ; Reichstädter, Marek (referee) ; Diviš, Pavel (advisor)
The bachelor thesis deals with the optimization of ICP-OES method to determination of iodine in mineral waters. At first, the Theoretic part characterize the iodine in general, next it concerns with it as the essential/biogenic element, which is necessary for the proper functioning of the human organism, with its occurrence in food and with its industrial utilization. In next chapters the thesis is describing analytical methods of iodine determination specifically ion chromatography and inductively coupled plasma optical emission spectrometry. The principle and instrumentation description of both methods are found. The Experimental part is focused on optimization of ICP-OES methods, device setup for IC, on preparation of samples of mineral waters and the samples analysis using both methods. The results of the Experimental part show a content of iodine in mineral waters accessible in the Czech Republic and the Slovak Republic.

Evaluation of the influence of the pasterization and filtration on selected chemical components of beer
Vopelková, Dominika ; Diviš, Pavel (referee) ; Pořízka, Jaromír (advisor)
The aim of this work was to study the influence of the pasteurization and filtration on selected chemical compounds in beer. Specifically, the influence on elemental composition, content of organic acids, carbohydrates and phenolic substances was studied. Optical emission spectrometry with inductively coupled plasma (ICP-OES) was used for elemental analysis of beer. Analysis of organic acids was evaluated by Ion chromatography. For analysis of carbohydrates was used High performance liquid chromatography with ELSD detector (HPLC-ELSD), phenolic compounds was evaluated by HPLC with diode array detector (HPLC-DAD). Data from analysis of beer was performed by usage of statistical methods (analysis of variance and principal component analysis). Parameters that showed the most significant differences between individual groups of beers were obtained. Correlations between the variables and the technological beer processing operations were found. 12 parameters of total 23 were affected. The effect of filtration and pasteurization was observed in content of the iron, silicon, potassium and magnesium, malate, monosaccharides glucose and fructose and phenolic compounds.

Altitude control of flying robot
Palacký, Tomáš ; Šembera, Jaroslav (referee) ; Baránek, Radek (advisor)
This bachelor’s thesis deals firstly with design and construction of a device for testing of altitude control algorithms of a flying robot. Secondly with creating and testing of an altitude control algorithm in order to apply findings while creating a copter control system. Provided is a selection and analysis of used hardware and software components – microcontroller AVR ATmega, ultrasonic sensor, motor controller and also communication interfaces IC, USART and SPI. Also design and realization of electrical wiring, circuit board and mechanical structure is being described here. The next section includes creation of software for microcontroller and PC application. The altitude control algorithm is developed using a simulation, furthermore tested and tuned for desired behavior.

Determination of selected parameters in foreign beers
Punčochářová, Lenka ; Pořízka, Jaromír (referee) ; Diviš, Pavel (advisor)
The aim of this thesis is determination of selected polyphenols, organic acids and elements (major and minor) in a foreign beers. Production of malt, beer production, beer types and beer styles are described in the theoretical part. Also analytical methods of beer analysis such as high performance liquid chromatography, iont chromatography and inductively coupled plasma optical emission spectrometry are described. The Experimental part deals with preparation of samples and calibration solutions, setting devices up and analysis of foreign beers samples. There were analyzed 14 foreign beers of which 11 samples were top-fermented beers, 3 samples were bottom-fermented. Four samples were produced in Belgium, three in England, three in Germany, two in the US, one in Holland and one in Poland. The results give an overview of the contents of compounds in foreign beers.

Draft beer analysis by HPLC-ELSD and IC
Vanduchová, Petra ; Vespalcová, Milena (referee) ; Diviš, Pavel (advisor)
In this bachelor thesis is discussed the brewing process and composition of the beer. The experimental part deals with analysis of polyphenolic compounds and carbohydrates by HPLC, analysis of organic acids by the IC and the ICP-OES method was used for analysis of elements. The HPLC method was used to determine eleven polyphenols. Gallic acid was the most represented compound of polyphenols and quercetin was the least represented compound. Glucose, fructose and sucrose were analysed by HPLC and the most represented compound of carbohydrates was glucose. The ICP-OES method was used to determine ten elements. Zinc was the least represented element in the analysis and phosphorus and potassium were the most represented in the analysis.

Determination of selected parameters in special types of beers brewed in the Czech Republic
Fähnrichová, Nikola ; Divišová, Radka (referee) ; Diviš, Pavel (advisor)
This bachelor thesis deals with analysis of special types of beer brewed in the Czech Republic using three instrumental methods. Polyphenols were determined by high performance liquid chromatography. To determine organic acids was used ion exchange chromatography. Elementary analysis was performed by inductively coupled plasma optical emission spectrometry. The theoretical part of the work describes technology of beer production, chemical composition of beer, especially groups of substances which were analysed in this thesis. Principle of used methods is also described. The practical part of the work deals with preparation of tested samples, calibration samples and process analysis. The obtained results of analysed substances are summarized in the tables, discussed and compared with results of analysis of other authors. For the analysis it was used eighteen different types of special beer produced in the Czech Republic.

Detection methods of energetic materials
Procházka, Michal ; Diviš, Pavel (referee) ; Friedl, Zdeněk (advisor)
A research on current methods of detection of explosives and related materials was made. At first the thesis studies methods of detection and analysis of explosives including chromatographic methods (TLC, GC, HPLC, IC), mass spectrometry and its variations, ion mobility spectrometry and infra-red spectroscopy. Next the attention is placed on detection of explosives in solid phase by X-ray detection, nuclear magnetic and quadrupole resonance and thermal neutron activation. Practical applications of these methods are of great importance in this thesis as well as their usage in the counterterrorist fight.
