Educational Tool for Coloured Petri Nets
Navrátil, Ondřej ; Kočí, Radek (referee) ; Rogalewicz, Adam (advisor)
Coloured Petri nets (CPN) are an extension of a standard place-transition Petri nets (P/T PN). Every token and place have its type (and eventually a value) and various inscriptions can be inserted into the net. CPN excel with great readibility and expresivity. At the same time, they carry a well-defined formal basis, which eases its computer simulation and allows limited verification of certain attributes to be performed. Motivation for doing this project is the simple fact that currently only one public software tool is available for CPN creation and simulation - CPNTools developed on the Aarhus university. The program, however, is quite complicated and hard to handle for an unexperienced user. The goal is to research capabilities and properties of both CPNs and CPNTools and on this basis design and implement a didactic application with swift and intuitive interface that helps users without deeper theoretical insight to get a grasp of the problematics.

Program for Generation of the Image Crosswords
Navrátil, Ondřej ; Pospíchal, Petr (referee) ; Kaštil, Jan (advisor)
Main topic of this thesis is the picross, a puzzle similar to well-known sudoku or criss cross. Central questions discussed in the text are automatic and semi-automatic generation of the rebus from digital images and solving and solvability of the puzzle. Characteristics and procedures described are demonstrated in the aplication picross, which was implemented as a part of this bachelor's thesis.

Study of Distribution Logistics in K-BREWERY TRADE
Navrátil, Ondřej ; Urban, Jan (referee) ; Bartošek, Vladimír (advisor)
In my bachelor thesis is a subject the study of distribution logistics in K Brewery Trade. The study is separated into three parts, theoretical, analysis and my own proposal of solution. The first part is focused on the theory of clasification of transport, logistics of transportation and characteristics of carriers and transport services. Analysis is focused on the form of distribution networks and the criteria for transport of goods between distribution centers of the selected company. My own proposal of solution is developed according to materials from the company.

Office and logictic building
Navrátil, Ondřej ; Ing. Michal Štrba. Ph.D. (referee) ; Pilgr, Milan (advisor)
Design of a steel supporting structure for one-storeyed hall based on ground plan of 60 x 80 m, clear height 10 m and total height 13,3 m. In the front part there is along the whole widht designed two-storeyed skeleton structure penetrating into the hall. From the second floor rods supported frontal part which exceeds ground plan by 2 m and on the right side is closed by pre-set cylindric structure with radius 8,6 m which covers the right frontal corner of building. The cylindric structure is around its perimeter distanced max 3,6 m from hall grand plan and is supported by posts. Both spaces had saddle roof with 8% slant, gutter edge in height 11,6 m, top line in height 12,8 m. Walls are around perimeter closed by horizontal atic in height of 13,3 m. Shape and dimensional design, load specification – stady, utility, climacic load. Calculation of imide forces and further static dimensioning of the main supporting elements and selected details. Elaboration of design documentation (dosposition, production drawing of the anchorage plan, details definited by project supervizor).

Analysis of proces fluid pretreatment for heat exchange purpose
Navrátil, Ondřej ; Kilkovský, Bohuslav (referee) ; Jegla, Zdeněk (advisor)
This thesis is devoted purification of a gas stream with solid and liquid particles. The problem described in the thesis is connected with a real industrial case – problem of operated waste gas incineration plant. Waste gas going to thermal incineration to flame of natural gas combustion contains solid and liquid particles. Presence of particles causes fouling of waste gas preheater. The main objective of thesis is analysis of situation and operating and space limitations and design of a suitable type of particle collector to reliable elimination of particles from waste gas before entering the gas preheater and thus to mitigation of fouling of preheater heat transfer area.

Surgical Aspects of Brain Ischaemia Flowmetry in a Clinical Practice and Experiment
Dostál, Jiří ; Přibáň, Vladimír (advisor) ; Vaverka, Miroslav (referee) ; Navrátil, Ondřej (referee)
Dissertation summary Surgical aspects of brain ischemia Flowmetry in a clinical practice and experiment MUDr. Jiří Dostál, Dpt. of Neurosurgery, Charles University, Faculty of Medicine Supervising Tutor: doc. MUDr. Vladimír Přibáň, Ph.D., Dpt. of Neurosurgery, Charles University, Faculty of Medicine The aim of this dissertation is to assess the options and benefits of a transit time flow measurement (TTF) in brain ischemia prevention in neurosurgery. Case reports from the Department of Neurosurgery, Charles University, Faculty of Medicine in Pilsen show the use and the limits of TTF. Presented case reports show the need of an individual approach in the case of a complex brain vessel surgery. A group of patients surgically treated for an unruptured middle cerebral artery aneurysm was analysed. Possible restriction of blood flow after the clip placement was quantitatively assessed by TTF in the first subgroup of patients. No quantitative flow measurement was performed in the second subgroup. There was no statistically significant difference between the two groups in terms of ischemia prevention. Some cases may entitle the surgeon to consider TTF use. TTF measurement is an invasive procedure and it demands a careful approach to the vessel and its preparation. The authors suggest to leave the use of the TTF to...
