Extraction of information from web pages
Caha, Tomáš ; Burget, Radim (referee) ; Komosný, Dan (advisor)
This thesis deals with the separation of information from websites of selected geolocation services. Methods of geographical location of network devices and amount of available data provided by chosen freely accessible geolocation databases. The data are summarized with focus on methods of obtaining information about IP addresses from APIs of particular databases. In the paper there are also presented ways used to develop the system for automatic estimation of geographic location of IP addresses specified in source file and process of comparing retrieved data with reference data. The system is created in Python and provides a simple way for verifying information about given IP addresses in five freely accessible databases. Furthermore, accuracy of the retrieved data is evaluated and five geolocation databases is compared.

Electronic notice board LCD
Chmelař, Petr ; Franek, Lešek (referee) ; Bradáč, Zdeněk (advisor)
This paper focuse at market research with digital signages, kiosks, and the subsequent suggestion directed on the concept of the new system and its hardware parts and software. The aim of this work is grounded on creating the concept of electronic boards, which is derived from the market research. The concept of the system is describing the principle of functioning of the digital signage, possibilities of controlling and system administration itself. The suggestion of the hardware part of the system contains the selection of appropriate mechanism for realization of the software part of the system and the proposal of controlling and signaling aspects, which are suitable for communication with users.

Comparison of flange connections design
Hrbáček, Jan ; Dohnal, Miloslav (referee) ; Buzík, Jiří (advisor)
Flange connections are type of connections frequently used in industry. There are hight claims for their dimensioning, strength and tightness. The proper and exact design can be made by calculation or by choice of standardized components (flanges, bolts, nuts etc.) accordig to requirements established by standart. This Bachelor´s thesis occupies itself with qualitative comparison of proposals for the strength design of flanged conections according to ČSN EN 13445, AD 2000 Merkblatt and ASME Code standarts. The programming language called Python is used in this Bachelor´s thesis.

Design and implementation of VoIP protocols tester
Polášek, Jakub ; Číka, Petr (referee) ; Krajsa, Ondřej (advisor)
This paper deals with ways and means of testing SIP or IAX2 based equipment and protocols itselfs. I analyse terminology and methodology for benchmarking of proxy and registrar servers as it was described in documents RFC 7501 and RFC 7502 from organization IETF. In the practical part is described the tester realization programmed in PHP programming language witch will use described methodology. Aplication is available in web based interface.

Visualization of multidimensional data using web technologies
Burian, Vojtěch ; Galáž, Zoltán (referee) ; Mžourek, Zdeněk (advisor)
Scope of this work is the problematic of data visualization. Data visualization is a useful tool to present and gather new information and thus get to better decisions. In theoretical part, data analysis topics are dealt with. Then specific types of graphs are listed and explained, and in next part problems with graph creation are pinpointed. Basics of graphic and web design are also mentioned. Practical part is focused on visualization of data of processed results of speech analysis, gathered from patients with Parkinson disease. Because majority of people in medical industry do not have, or is not able to work with specialized software (such as Matlab), outputs in HTML table and SVG format were created based on Python programming language. Both these parts are accommodated into webpage, which can be easily opened in web browser installed in most of computers regardless of operation system used.

Cluster analysis of data traffic
Nagyová, Simona ; Martinásek, Zdeněk (referee) ; Blažek, Petr (advisor)
This thesis is meant to present the methods of cluster analysis, their use for detecting network traffic anomalies. It deals with various types of cyber attacks particularly DoS (DDoS) attacks. It contains a list of well-known DoS attacks. Also includes a program in Python, using the k-means method for detection of anomalous traffic.

Monitoring of communication properties in Internet
Iľko, Pavol ; Červenka, Vladimír (referee) ; Komosný, Dan (advisor)
This thesis deals with measuring transmission parameters of the Internet network, in particular latency of ping, SSH protocol and bandwidth. The thesis is divided into a theoretical and a practical part. Theoretical part describes PlanetLab network, its brief history and contemporary projects. At the same time, tools for data mining from web pages are described. These information obtained from the theoretical part are used for creating PlanetLab nodes list and for programming applications which measure the network transmission parameters. Applications, list of nodes and obtained data are attached on DVD disc.

Performance testing of networks with Mikrotik components
Kaláb, Vojtěch ; Kubánková, Anna (referee) ; Mašek, Pavel (advisor)
The goal of the thesis is to develop and describe application for Mikrotik Network stress testing. The aplication is developed in high-level scripting programming language Python. The aplication allowed us to configure and display in diagram our connected routers and network stress testing. Theoretical part is focused on Mikrotik company, their development and products. Next part is about theory of network stress testing and graph theory. The last part is about aplications development, programming language Python and used tools and libraries.

Programmable IR receiver
Géze, Daniel ; Frýza, Tomáš (referee) ; Fedra, Zbyněk (advisor)
The aim of this bachelor thesis is design and realization of solutions for hardware and software programmable IR receiver. IR receiver is actually a logic programmable automat, which responds to commands from the remote broadcast communications protocol RC6 designed by Philips. Codes of these commands can be assigned to different actions. Using the configuration application in PC by any code of buttons it is possible to order firmly programmed codes in a flexible management processor Cypress (CY8C29466). Configuration software for the PC has been created by using the python programming language. The main purpose of this device is helping for the handicapped people.

Analysis of geolocation databases
Zima, Štefan ; Červenka, Vladimír (referee) ; Komosný, Dan (advisor)
This thesis is focused on collecting data from commercial geolocation databases and its analysis. The theoretical part discusses techniques of IP geolocation, briefly describes commercial geolocation databases and mechanisms for accessing their geolocation services. The practical part of this thesis involves implementation of scripts for collecting and modification data retrieved from commercial geolocation databases for further analysis. First script collects the data and store them in output files in specified format. Second script modifies gathered data to achieve better accuracy. Detailed analysis is performed afterwards. Analysis is performed at several levels. This includes country, region and city accuracy as well as accuracy on latitude and longitude parameters. Output of this analysis will be conclusive, and will also display accuracy of tested geolocation services. The aim of this thesis is to analyze currently available commercial geolocation services and to prove their accuracy. Used scripts are implemented in Python programming language in version 3 using modules urllib, re and json. Scripts are test on commodity hardware with Linux operating system.
