Welding of socket from C-Mn steel
Boček, Martin ; Mrňa, Libor (referee) ; Kubíček, Jaroslav (advisor)
Final thesis, elaborated within the master study in the field of Manufacturing technology, deals with analysis and solving of weld cracking problem in welds of anti-roll bar socket for passenger car. Sockets material is fine-grained low-alloy steel S420MC. For better understanding of the problem, a literary study has been elaborated, describing the issue. Next, an analysis of parts material and its weldability, has been conducted, according to ČSN EN 1011-2 standard. After an analysis of cracks and considering current conditions of sockets welding a series of experiments has been designed to evaluate impact of different process parameters on final weld quality. Experiments results have been used to compile a series of recommendations for adjustment of the welding process and to eliminate weld cracking. The results of the experiments were used as a basis for elaboration of WPS protocol.

Knee system C-Leg and its application to transfemoral amputation
Červený, Jan ; Pavlů, Dagmar (advisor) ; Véle, František (referee)
Title: Knee System C-Leg and its application to transfemoral amputation Objectives: Aim of this work is characteristic of knee system C-Leg prosthetic leg construction with knee system C-Leg applied in patients with transfemoral amputations, the possible setting, used in combination with a common type of Socket and compare the affect of the image of the patient's gait. Another target is a description of possible mistakes in the setting of the C-Leg and their manifestations in the initial use and walking Methods: In this work I used the method of analysis previously identified and published knowledge and experience with the knee of C-Leg, its buildings, the settings recommended by the manufacturer and walk to school transfemoral amputation. Compiling the various types of Socket used to walking training, the published results of therapy in patients amputated and its own experience, I worked under subsequent acts, which occurred during therapy. Results: In keeping with the recommended structure for the transfemoral prosthesis and knee system with the C-Leg and then comparing the different types of Socket and results of therapy in the rehabilitation wards, I described the side effects are possible in the image the patient's gait. The presented findings describe the possible recommendations for the...

Computer Remote Control Using Cell Phone
Řeháček, Prokop ; Jaroš, Jiří (referee) ; Pospíchal, Petr (advisor)
This thesis deals with the creation of remote control application using Bluetooth wireless technology. The work introduces a modern Android operating system and software development for this system. Application of remote control consists of parts: client for Android OS and server for GNU/Linux. The client was implemented in Java and the server has been created using the Qt toolkit and C++. Software development is divided into parts: design, implementation and testing. The result of this thesis is software that can control multimedia programs for audio and video files.

Network Interface for Keyword Spotting System
Skotnica, Martin ; Glembek, Ondřej (referee) ; Szőke, Igor (advisor)
A considerable part of the research in computer science is dedicated to speech recognition as the speech-controlled systems become useful in many applications. One of them is the keyword spotting which makes possible to find words in audio data. Such a detector is developed at BUT Faculty of Information Technology. The goal of this work is to propose a network interface to this keyword detector based on client/server architecture. Client connects to the server and sends audio data. Server runs keyword detector with this received data and sends the result of keyword spotting back to client. Finally client visualizes the result and interact with user.

Interception of Modern Encrypted Protocols
Marček, Ján ; Korček, Pavol (referee) ; Kajan, Michal (advisor)
This thesis deals with the introduction to the security mechanism.The procedure explains the basic concepts, principles of cryptography and security of modern protocols and basic principles that are used for information transmission network. The work also describes the most common types of attacks targeting the eavesdropping of communication. The result is a design of the eavesdropping and the implementation of an attack on the secure communication of the SSL protocol..The attacker uses a false certificate and attacks based on poisoning the ARP and DNS tables for this purpose. The thesis discusses the principles of the SSL protocol and methodology of attacks on the ARP and DNS tables.

Design of Transtibial Posthesis With Use of Additive Manufacturing Technology.
Kopecký, Martin ; Náhlík, Luboš (referee) ; Koutný, Daniel (advisor)
The thesis deals with the design of a transtibial prosthesis by additive manufacturing technology. Based on walking biomechanics and the current situation of knowledge a prosthetic foot has been designed for a patient with low level of physical activity. Furthermore, the thesis describes the design of an individual socket for the patient. The socket has been designed by reverse engineer procedure based on the three-dimensional geometry of patient´s stump obtained by 3D scanning. Testing samples of the foot and the socket have been made for the check of functionality of both the devices and then subjected to mechanical tests in accordance to the methodology regulation ISO 10328. Finally, the thesis depicts the FDM technology used for the production of functional samples of the designed devices; assembly of modular transtibial prosthesis and its testing by the patient.
