Generator of Analysers of Documents Defined by RELAX NG
Šimonek, Jan ; Janoušek, Vladimír (referee) ; Martinek, David (advisor)
This bachelor's thesis deals with automatization of XML loading. This is accomplished by a generator of XML analyser. The generator (translator) takes a XML scheme in RELAX NG and it produces analyser in C++. The generated analyser is capable of unmarshalling and validating data from XML, providing access to the data and marshalling the data back to XML. Usability of this process is demonstrated on examples. Theory of the XML, XML schema languages and validation is also discussed.

Validation of Web Accessibility
Pojer, Petr ; Trchalík, Roman (referee) ; Očenášek, Pavel (advisor)
This thesis deals with the accessibility of websites and its validation capabilities. The essential part is the analysis of current methodologies used in the world - with a focus on U.S., Europe, and especially the Czech Republic. It is followed by an overview of the best known tools for checking accessibility of their properties based specification, design and implementation of custom applications, which is the result of this work.

Validation of Network Parameters Based on Network Monitoring
Martínek, Radim ; Veselý, Vladimír (referee) ; Žádník, Martin (advisor)
The Master's Thesis presents a theoretical introduction, familiarization with the issue and a implementation for a solution of a "network parameter validation" tool, which is founded on principle of network traffic monitoring. Firstly, the current development of computer network setup is analyzed with its limitations. This is an initial point for an introduction of a new approach for implementation and verification of required network setting, which uses techniques of verification, simulation and validation. After the introduction into the context, validation techniques are specifically examined. The Thesis main contribution lies in the capacity to determine appropriate parameters, which can be used for validation and also for implementation of the tool, which ensures validation process. The network traffic, which characterizes the behavior of the network, is collected by NetFlow technology, which generates network flows. These flows are consequently used by the designed tool used for validation of required network parameters. This process overall verifies whether the main computer network requirements have been met or not.

Optimization of Bosch DNOX 5.x Pump Module Testing Matrix
Friedl, Michal ; De Bernardi, Olivier (referee) ; Dundálek, Radim (advisor)
Táto diplomová práca sa zaoberá optimalizáciou validačných testov pre produkt firmy Robert Bosch určený na úpravu výfukových plynov vznetových motorov, tzv. Denoxtronic 5.x, konkrétne jeho najkomplikovanejšiu časť – Pump Module. Zhrnutím a analyzovaním porúch objavujúcich sa v reálnej prevádzke tak poskytuje spätnú väzbu pre oddelenie vývoja a navrhuje, akým mechanizmom by mali byť v budúcnosti validačné testy optimalizované.

Ventilation of a cytostatic laboratory
Kicko, Peter ; Štětina, Josef (referee) ; Charvát, Pavel (advisor)
The main goal of this thesis is an introducing and guiding the reader with all important aspects of a proposal of ventilation system for cytostatics laboratory, from theoretical knowledge about the issue via familiarization with an appropriate legislative statute, a demonstration of relevant calculations needed for the project, a proposal in the form of technical reports as well. In this thesis the process of validation, which is needed for installed technology in the cleanroom, is also described. The thesis is supported by drawing documentation of real ventilation project for cytostatics laboratory, which follows the aforementioned technical report and calculations.

Car Door Handle FEM Model Creation and Validation for Crash Simulations
Raffai, Peter ; Korouš, Jan (referee) ; Ramík, Pavel (advisor)
The aim of this master’s thesis was to create a component model of a door handle stiffener used by the Volkswagen concern, which can be used for crash computations. Also to tune its parameters the way, its behavior corresponds the most to the real part’s. In the theoretical part the current regulations of the Euro NCAP are presented, concerning the testing and evaluation of the passive safety of new vehicles. Attention is focused on the evaluation of the side impact barrier tests, where the effect of the door handle stiffener’s damage is reflected the most. Shown are the reasons for the effort to simulate the real behavior of the stiffener, the factors, which initialized the born of the studied problem. The practical part starts with the creation of the FEM mesh of the part based on its 3D CAD model, also describes the requirements for the mesh quality, as well as the used tools and methods. Further on investigated are the characters of real damages of the door handle area during side impacts, based on which the component tests are proposed for the validation of the simulation model. Experimental research consists of the stiffener’s testing for simple bend and twist loads, three specimens each. After the execution of the tests the results get compared with the corresponding simulations. Modifications are made on the model according to the acquired results: refinement of the FEM mesh, new material model usage with failure for shell elements and definition of real material characteristics for the used thermoplastics. The latest obtained simulation dependencies are compared with the measured values again, the results are evaluated at last.

Optimizing the Manufacturing Process in a Company
Vrána, Jakub ; Novák, Viktor (referee) ; Videcká, Zdeňka (advisor)
This thesis deals with the management of the production process, focusing on unproductive activities. It comprises analysis of the current situation in the company Teva Czech Industries s.r.o. (the TCI) and suggestions for improvement measures. The first chapter presents theoretical basis for processing work. PMT methods, namely MTM and MOST, lean production with a focus on 5S, TPM and Kaizen are described. The second chapter is focused on the company TCI, core business, organization structure and analyzes the current status. It’s focused primarily on the process of critical non-manufacturing operations and the changeover cleaning process. The third chapter, following the analytical part consists of the proposed recommendations. The fourth chapter deals with the final evaluation.

Manufacturing Processes Management with Usage of Simulation Tools
Richtr, Jiří ; Karpeta, Vladimír (referee) ; Šunka, Josef (advisor)
Simulace výrobních procesů pomáhá optimalizovat výrobu, logistiku a další systémy, díky čemuž dochází ke snižování nákladů a racionalizaci vnitropodnikových procesů. Využitím diskrétní simulace programu Witness Power with Ease se v diplomové práci optimalizuje logistický tok materiálu ve společnosti Hella Autotechnik, s.r.o. Práce přibližuje metody a jednotlivé fáze tvorby modelu včetně jeho validace a navrhuje vylepšení, díky kterému by mělo dojít ke snížení nákladů na dopravní služby o 24 400 Kč měsíčně.

Unsupervised learning
Kantor, Jan ; Sáblík, Václav (referee) ; Honzík, Petr (advisor)
The purpose of this work has been to describe some techniques which are normally used for cluster data analysis process of unsupervised learning. The thesis consists of two parts. The first part of thesis has been focused on some algorithms theory describing advantages and disadvantages of each discussed method and validation of clusters quality. There are many ways how to estimate and compute clustering quality based on internal and external knowledge which is mentioned in this part. A good technique of clustering quality validation is one of the most important parts in cluster analysis. The second part of thesis deals with implementation of different clustering techniques and programs on real datasets and their comparison with true dataset partitioning and published related work.
