Security analysis of wireless Wi-Fi network
Passinger, Jiří ; Doležel, Radek (referee) ; Bartl, Milan (advisor)
This project is concerned with the security of Wi-Fi network. It defines security and introduces the principles of some security systems which are consequently instructed for its breakthrough, out of which follows the nature of security failures. The main emphasis is put on the current security issue of Wi-Fi Protected Setup (WPS) technology. Consequently, it is concerned with the putting into service of this technology in GNU/Linux distribution OpenWrt on Wi-Fi router TP-LINK TL-WR1043ND. The project is concluded with the suggestions for the correction of the security failure.

Drone localization and navigation in a familiar environment without GNSS
Pintér, Marco ; Janoušek, Jiří (referee) ; Raichl, Petr (advisor)
This thesis is aimed at development of the localization system without using GNSS. The first part describes technologies, enable determination of position in the area. Methods for determining distance between transmitter and receiver are also described. In the next part of the thesis describes ROS communication form with flight controller PixHawk. On the basis of the acquired knowledge is described choosage of preferred technology and method of determination of the distance between transmitter and receiver.

Geoprocessing services in environment of the internet with specialization in ArcGIS
Bilík, Jakub ; Grill, Stanislav (advisor) ; Brůha, Lukáš (referee)
Geoprocessing services in internets environment from view of ArcGIS Abstract The aim of this work was explore problems creating geoprocessing services in software of firm ESRI. In first section of bachalors work was pursued literature search, that is engaged in geoprocessing services. It's introduced summary projects and use cases, that implement geoprocessing services in spatial data infrastructure. It's solving in the work creation geoprocessnig services in environments of products firm ESRI. With use ArcGIS server is created map and geoprocessing service. With use ArcGIS JavaScript API is incorporated this services to web site. Key words: geoprocessing, web services, ArcGIS, JavaScript API, WPS

Bezpečnostní rizika domácích bezdrátových sítí
Kaplanová, Lucie
This bachelor thesis describes the problem of home wireless networks security and is divided into two parts. The first part of this thesis is dedicated to authentication and encryption mechanisms according to the standard IEEE 802.11, attacks, methodologies, and tools of penetration testing. The second part of the thesis deals with the design of hardware configuration and creation of a test scenario used for systematic verification of security standards, using various complexity of the key. According to the results drawn from the performed analysis, the recommendation of home wireless networks security is presented.

Security Assessment For Ieee 80211 Family Of Standards
Šebestová, Dominika
This paper deals with analysis of security of wireless networks. It describes software intended for testing the security, specifically tools for Linux distribution of KALI. Furthermore it focuses on practical testing on an experimental network, where the functionality and efficiency of tools using brute force attacks, weakness in protocols or human errors are tested.

Welding of the sanitary gully
Skalník, Vít ; Vaněk, Mojmír (referee) ; Kubíček, Jaroslav (advisor)
The aim of this paper is to plan out and realize an optimalization for the welding process of parts of a sanitary gully. Problematics during the welding process of the aforementioned parts together with the usage of welding fixture were explained. On the basis of characteristic signs of welding, an application of other methods was evaluated and the optimal option for the welding process was chosen. During the selection process, hygienic regulations of a non-state funded organization EHEDG (European Hygienic Engineering and Design Group) were taken into account. Furthermore, suggestions for adjustments of the welding process of the forefront of the gully were analyzed. The next step was the realization of the chosen plan and its testing. Part of the process was the implementation of a technological procedure and execution of WPS (Welding Procedure Specification). The end of this paper considers the tecnological-economic contributions of the changed in the procedure.

Welding head of the longwall shearer
Adam, Karel ; Sigmund, Marian (referee) ; Kubíček, Jaroslav (advisor)
The aim of this bachelor thesis is to describe the structure and purpose of the longwall shearer drum to descriebe the technological process and to design the technology. Shearer heads are made by welding, MAG method with a protective atmosphere of CORGON 18 (18% CO2 + Ar) was selected. Increasing the strength of the knife holders, made from steel 15 230.3 to 1600MPa and welding to the helical segment of S355J2 + N steel, these clamps cracked cold. An error has been detected by reviewing the entire process and performing calculations. The preheating temperature was too low and was therefore increased to 270 ° C along with the stay for 2 hours at this temperature. Part of the thesis is a sample of the test weld of the rupture holder.

Welding of aluminum and its alloys with a focus on developing teaching methodologies, teaching methods and textbooks for teaching in welding school EGE, spol. s.r.o. the welding process according to EN ISO 4063: 131
VIK, Radovan
The first part briefly defines the theory of the creation of educational materiál. The following chapters describe the history of the fusion welding, the aluminum and its alloys, definitions of basic electrical and welding terminology. Briefly is described health and safety during welding work and fire protection. The following sections describe in detail the hand welding of aluminum and its alloys, method 131 (MIG), welding machines, equipment, protective gases, gas cylinders, pressure reducing valves. Another part is focused on the defects generated during welding of aluminum and its detection and iterpretation. The final part discusses the requirements for qualification of welders.
