Self-organizing MESH wireless networks
Němec, Petr ; Burget, Radim (referee) ; Růčka, Lukáš (advisor)
This master thesis deals with self organized Mesh network. It describes routing and particular routing protocols, which are used in these networks. The thesis deals with Mesh network QoS assurance. Analysis and theoretical background of Mesh networks, routing and router protocols are included in the first chapter. Basic models of assuring Quality of Service are also described. Those are Best Effort, IntServ and DiffServ. Second chapter describes the devices used in the specific Mesh network topology - Trospos 5210 MetroMesh router produced by Motorola Canopy. Basic settings and properties required to establish a Mesh network are described. Next part of the thesis is the design implementation, which involves creation and configuration of the Mesh Network. Network configuration consisting of two Gateway points and afterwards behaviors of the network in a steady state versus one gate failure are compared. Furthermore, implementation of QoS according to components that support two types of QoS assurance regarding type of bandwidth reservation and defined traffic classes. In conclusion, the thesis describes measurement methods of QoS parameters for chosen applications, evaluation and comparison of measurement results for both types of Quality of Service assurance.

Laboratory exercises creation for course Sensor systems
Štětina, Vítězslav ; Jelínek, Mojmír (referee) ; Šimek, Milan (advisor)
Topic of bachelor thesis is Laboratory exercises creation for course Sensor systems and describes the theoretical and practical solutions focused on the creation of 5 laboratory experiments. To the laboratory exercises is used a programming language nesC, operating system TinyOS and other programs. In 5 chapters describe the actual instructions for laboratory exercises. They are composed of the basic tasks to complex assignment. The workflow is a task assignment, a list of necessary equipment, the procedure for creating the main part of program and subsequent installation to the node or base station. A part of the task is to analyze the source code and description of new orders compared to previous exercises.

Design of the engineering structure
Svoboda, Adam ; Volf, Marek (referee) ; Klusáček, Ladislav (advisor)
The bachelor thesis deals with design issues of industrial buildings and is focused especially on design and assessment of short corbels. The first part of the thesis consists of a translation of technical text published by prof. J. Schlaich (E DIN 1045-1). In the second part of the thesis is the gained knowledge applied on assessment of existing industrial structure SUAS a.s. in Vřesová. For the analysis of short corbels is used the strut-and-tie model and the method of limitation of concrete compressive stress at the nodes of the strut-and-tie model. The thesis concludes with structural strengthening of nonconforming short corbels by using prestressed cables to ensure safe operation of the crane runway.

Analysis of the stator and rotor pack termination effect on the synchronous machine by FEM
Michailidis, Petr ; Valenta, Jiří (referee) ; Skalka, Miroslav (advisor)
This thesis deals with simulation’s possibilities of the electromagnetic fields in electrical machines. A finite element method is the final element technique. The content of this thesis is a model and mesh creation and electromagnetic simulation of synchronous machine. The stator and rotor pack termination effect on the synchronous machine.is analyzed by finite element method in ANSYS program. The type of the stator termination pack is described by four segments. The magnetic field distribution is deformed due to the material properties of used segments. In the next part a methodics of mesh creation is shown. The mesh quality (in term of elements number and elements shape) is important due to the solution accuracy and speed.

Connecting Knots and Their Influence on the Breaking Strength of Dynamic Rope
Komorous, Miroslav ; Vomáčko, Ladislav (advisor) ; Kulich, Marek (referee)
Title: Connecting Knots and Their Influence on the Breaking Strength of Dynamic Rope Aims Aim of the work is to find out the breaking strength of dynamic rope and the influence of connecting knots on the decrease of its breaking strength. Method: We use the method of testing maximum weighting of dynamic ropes. Measurement was done on a horizontal tearing machine in the Strojirensky zkusebni ustav in Jablonec nad Nisou. Results: Bigger breaking strength achieved the rope Beal Buster. It was 23.61 kN. The rope Beal Booster achieved the breaking strength 18.46 kN. The difference between these ropes is 5.5 kN. We recommend the eight knot as a connecting knot for the rope Unicore, whose breaking strength was 15.4 kN. This knot decreased the breaking strength of the rope at least. We found out the nine knot as the most sufficent knot for the ropes Beal Booster. Its breaking strength was 15.58 kN. Key word: dynamic rope, connecting knot, knot, breaking strength
