Cylinder unit of motocycle two-stroke engine
Stejskal, Miroslav ; Novotný, Pavel (referee) ; Píštěk, Václav (advisor)
Miroslav STEJSKAL Cylinder unit of motorcycle two-stroke engine In the beginning is briefly described two-stroke engine features. Furthermore, according to the set of basic geometric and thermodynamic parameters, the maximum pressure in the cylinder during one engine cycle. For the selected operating modes are carried out strength tests of the upper piston and connecting rod eye. In conclusion, the results are evaluated.

Survey and Diagnostics of Reinforced Concrete Structure
Haloun, Jan ; Heřmánková, Věra (referee) ; Anton, Ondřej (advisor)
The first part of this diploma thesis is about late and current methods used in Engineering surveys. The theoretical part is focused on description of individual testing methods and their evaluation based on relevant standarts. Detailed description of diagnostic methods is dependent on methods used in a practical part. The practical part is focused on defining of material characteristics of used materials and way of reinforcing of reinforced concrete elements. Based on those defined pieces of information the static recalculation of girder and pile was made.

Survey and Diagnostics of Reinforced Concrete Structure
Richterová, Dominika ; Heřmánková, Věra (referee) ; Anton, Ondřej (advisor)
The main theme of this diploma thesis is a building survey and diagnostics of a reinforced concrete construction. In the first, theoretical part the focus lies on a description of each method for testing constructions and their evaluation. The second, practical part focuses mainly on finding of material characteristics and reinforcement of particular parts of the construction. On basis of obtained information, the final part of this paper focuses on static assessment of chosen parts of the construction.

Determination of micro and macro elements in bottled water by ICP-OES technique
Herman, Vít ; Vespalcová, Milena (referee) ; Diviš, Pavel (advisor)
This Master’s thesis deals with the determination of selected micro and macro elements in bottled water purchased in retail chains Czech Republic. There are described macro elements and micro elements that occur in the waters, bottled waters legislation and the most frequent used instrumental methods for elemental analysis. In this work for the analysis of bottled water were used methods optical emission spectrometry with inductively coupled plasma (ICP-OES) and ion chromatography (IC). Elemental composition of bottled water after analysis corresponded to the composition indicated on the labels, there were recorded only minor deviations from the reported concentrations. All bottled water meets the conditions of the legislation of the Czech Republic. The measured data were statistically processed in the XL Stat program and by multivariate data analysis was examined whether it is possible to individual bottled water from each other based on the analyzes differentiate, which can help in verifying the authenticity of bottled water and in the detection of adulteration of bottled water for profit.

Modification of a motorcycle spark ignition engine
Poulíček, Matěj ; Ramík, Pavel (referee) ; Kaplan, Zdeněk (advisor)
This diploma thesis is about possible modifications of four-stroke motorcycle petrol engines for increasing power. It also deals with the modification of the Aprilia Leonardo 250 engine from a 2-valve variant to a 4-valve variant, the simulation of this engine and the proposed solution in the GT SUITE. Attention is also paid to the strength control of the crank mechanism of the engine.

Materials for Production of Small Firearms
Neužil, Tomáš ; Lidmila, Zdeněk (referee) ; Molliková, Eva (advisor)
The aim of this thesis is to summarize information of small firearms, both in terms of their historical development and the origins of the crafting firearms, through the development of locks and a history of the weapons, which were during this development invented, to the emergence of a single bullet, which is still used today, so from the perspective of our time focusing on the choice of barrel materials, the issue of loading and fatigue barrel and bore when fired and conventional production technologies barrel bore.

Preparation and Realization of Technical Survey of the Building
Richterová, Dominika ; Heřmánková, Věra (referee) ; Anton, Ondřej (advisor)
This bachelor's thesis in its first part focuses mainly on the theoretical description of the methods applicable in the diagnosis of building constructions; and not only the current methods, but also those previously used. In addition to descriptions and introduction of these methods, the descriptions of ways of implementation and evaluation possibilities according to the given standards are included, which is the specific content of the second part of the thesis. The last part is practical which is mainly approached by determining of characteristics of materials used in the construction or the reinforcement of the construction.

Survey and Diagnostics of Building Construction
Resl, Jaroslav ; Cikrle, Petr (referee) ; Anton, Ondřej (advisor)
The thesis is focused on the overview of the diagnostic methods for engineering surveys reinforced concrete constructions. The practical part explains engineering surveys of industrial building, evaluation of concrete strength on existing building and results from search reinforcements on individual elements. Next part is focused on load testing precast floor slab removed from construction and evaluation load capacity. The last part include structural design of elected parts (precast floor slab and beam).
