Forensic Optical Fingerprint Comparator
Dvořák, Marek ; Klubal, Ondřej (referee) ; Drahanský, Martin (advisor)
My Bachelor Thesis deals with the design and creation of an application that replaces the function of forensic optical comparator. It also describes features of fingerprints and their prominent points, which are used for recognition of individuals. Work with fingerprints is very sensitive as for the quality of images. For this reason a Gabor filter has been implemented and described. Furthermore, the thesis describes basic functions used for work with images.

Design of a 3D scanner for educational purposes
Paprsek, Adam ; Maxa, Jiří (referee) ; Vyroubal, Petr (advisor)
The aim of the submitted semestral project is research of 3D scanning object methods. The 3D scans utilization and types of these scans have been mentioned in the first chapter. The scanners are grouped into two basic methods – contact and contactless. The second chapter is dedicated to 3D model measurement principles, which are described in detail in four sub-chapters. In the following chapter is described design with complete realization 3D scanner with the implementation of the application for its controlling. Last part of the thesis concerns the 3D model editing and method evaluating.

Data Acquisition from HTML Sites
Komenda, Tomáš ; Šimek, Václav (referee) ; Straka, Martin (advisor)
This work describes scope of creating application for extraction and following data from HTML sites. This work engages in lexical analyze and parsing HTML. This work describes filtration of data from HTML sites. This work describes saving of data in database and XML documents, creating of dynamic HTMP pages, timer cron, GNU utility wget, sending of SMS, sending email and extraction of date from internet. Final chapters describe two web applications. These applications follow data from HTML sites and inform users about changes.

Software for seeking vulnerable computers in network
Krkoš, Radko ; Pelka, Tomáš (referee) ; Polívka, Michal (advisor)
This thesis concerns about computer system and network infrastructure security. It describes the topic of security holes and vulnerabilities and discusses possibilities for computer attack defense. Common security holes and client and server systems configuration errors are described. There are stated simple rules and advices for configuring network environment according to security and minimalization of failure or violation risk due to security holes and vulnerabilities. Thesis adresses approaches of security hole detection in programs and devices entrusted to administrator, device and security holes inventory control and prevention possibilities. Thesis describes how to execute self security audit and how to process its results. It suggests techniques and methods to administer network, server, or intranet during its lifespan according to security. It also analyses existing available software and evaluates its features and resources with regard to security topic. Software is chosen to simplify work for administrator in some or more parts of security management like network condition analysis, error and vulnerability detection in computer systems, network infrastructure, web applications or applications for network alternation detection. Thesis recommends requirements for security audit application and discusses eligible features in regard of functionality and added value. Created set of scripts simplifies administrator's work by automating common and time consuming tasks and delivers information in compact and simple form, what makes the work more comfortable and shortens the reaction time to crises such as discovery of new security hole or security breach.

The use of optical methods in the diagnosis of electrical machines
Tobolák, Petr ; Kuchyňková, Hana (referee) ; Janda, Marcel (advisor)
This term describes questions of scanning rotors of asynchronous motors using 3D scanner. At the beginning it deals with a theory of asynchronous motors, defects of these machines and last but not least also questions of 3D scanning. Directly it focuses on a practical processing of measured rotors and their necessary modifications using of a program GEOMAGIC. It includes a diagnostic of deviations of scanning components of rotors with a model created on a program AUTODESK INVENTOR and posiible reasons of their creation.

Environment mapping
Mohorko, Martin ; Pavlík, Jan (referee) ; Bilík, Martin (advisor)
This bachelor thesis deals with the description of possible ways of mapping the unknown environment, which could be in this case both environments - aerial and terrestrial. It is focused on mapping by radars and 3D scanners, through their history, distribution, scanning methods, methods of displaying data or description of output data to their practical application. Furthermore based on selected criteria, methods were compared and it was explained why and which method is preferable than the other one. There is also in this work mention of other methods used for environment mapping of today and their use and potential for several future applications. In the conclusion was outlined the possible use concept on the radar locating system in connection with the 3D scanner.

Using of modern software support in the projection practice of process engineer
Zajíc, Jonáš ; Babička Fialová, Dominika (referee) ; Jegla, Zdeněk (advisor)
The presented MSc. thesis is focused on the introduction and application of PDMS software in the process piping designing area. The introduction to the employing of the PDMS software is elaborated in the first part of the thesis as practical user manual of this software followed by the benefits of this software as a recognized supportive design program are consequently illustrated on partial solved cases from common design practice. The particular benefit of deploying PDMS in design practice is demonstrated in the thesis by economic evaluation of two selected solved industrial projection cases where design optimization of process piping system is solved with the support of this software system. Introduction of new ones broadening possibilities and current trends in the supportive design software systems, specifically using the scanner and supporting Everything3D are also presented as part of the thesis on a concrete example of the reconstruction of the boiler room.
