Design of Portable 3D Scanner
Štigler, Jaroslav ; Rubínová, Dana (referee) ; Sovják, Richard (advisor)
The topic of this bachelor‘s thesis is design of handheld 3D scanner. This scanner belongs in the higher price category. This thesis deals with problems like long working time, watching monitor during scanning, versatility and safety measures from mechanical damage. Ergonomic solution is also very important. This design is based on a simple and functional shaping. Shaping and color solution corresponds with its use in industry. This scanner also can be used in other fields (for example: medical sector, design, archeology, etc.).

Network Protection Using NetFlow Data
Czudek, Marek ; Tobola, Jiří (referee) ; Žádník, Martin (advisor)
This thesis deals with the possibility of greater security of network based on NetFlow protocol. Specifically, the detecting network scans based on predefined rules to found this anomaly in the NetFlow data. Next part is the possibility of retrospective data analysis, thereby achieving more accurate detection of attacks on the network. In this work designed application uses predetermined rules to detect the scans and then looks the flows towards the ports witch are protected by the application and than compares with detected scans. In this way, more accurate detection of attacks is achieved.

Automatization of an optical setup for time-resolved spectroscopy
Šimek, Daniel ; Klenovský, Petr (referee) ; Dvořák, Petr (advisor)
Time-resolved spectroscopy is a modern method enabling the analysis of the dynamics of quantum luminescence transitions. This method uses ultra-fast light pulses to study materials, which makes it possible to observe the time evolution of luminescence quenching and thus provides additional information for static absorption and emission spectroscopy. This diploma thesis deals with the automation of the optical setup used in the Optical and Plasmonic Laboratory at Ceitec Nano for performing time-resolved spectroscopy. As part of the work, an application was created enabling communication with 13 devices used in the laboratory. The application automates already performed measurements, and in addition enables the scanning of samples, which was not possible due to time constraints due to the manual control of the stage movement. At the end of the work, test measurements are performed, with a discussion of their effectiveness and time savings for the user.

Coordinate measuring machines
Palásek, Vítězslav ; Zachoval, Luboš (referee) ; Zachoval, Luboš (referee) ; Pernikář, Jiří (advisor)
This graduation work is about co-ordinal measuring machines (CMM) with optical reader system and optical CMM. In accordance with submission and in terms of survival well known contactless systems the direction is to make methodology objective classification of rating with granting summary of these systems. The first part contains optical principles for visual scanner in CMM and optical CMM. Ist is described there principle of contactless obtaining steric digital version of measured object with using laser and optical facilities. The second part contains brief makes survey of these contactless systems and their component which are used for co-ordinal measuring. The survey is devided into optical readers, which are put on CMM brake or on mobile measuring brake and on optical CMM, which localize position measuring/sensing head in the space or they read measured object from specific distance – fotogrammetric. Characteristic of offered systems and chart with technical data are mentioned with each maker. The third and fourth part is about submission methodology for objective choice suitable sort of reader, optical CMM in target of characteristic reader system quality. And from this methodology is given the choice of suitable exponent stationary measuring machine with contact and contactless way of reading and their comparison.

Network Protection Using NetFlow Data
Čegan, Jakub ; Žádník, Martin (referee) ; Tobola, Jiří (advisor)
This thesis deals with the using of NetFlow data for computer network protection. First are described some types of network security threats. After study of these threats and many experiments were designed detection rules for them. New detection form were designed too. It is working with two step detection of threats.

Advanced network device scanner
Procházka, Michal ; Blažek, Petr (referee) ; Holasová, Eva (advisor)
The master thesis focuses on problem of identifying device types on a local network. The work explores current methods for device recognition on local networks and examines a survey of open-source tools capable of identifying these devices or gathering additional supplementary information. The discovered tools are compared based on several criteria. Furthermore, a laboratory environment is created for testing the identified tools as well as for testing own implementation. Subsequently, this thesis presents a proposal for the own implementation of a device identification method and the retrieval of advanced information about these devices. The main part of the work focuses on describing several possible methods of device identification, including practical examples. Scripting of the practical examples is implemented in Python or through the command line. Based on the outlined approaches, the thesis presents a list of all recognized devices from the experimental setup. Finally, the methods are compared in terms of network utilization during scanning.
