Optimal path planning for electric vehicles
Horák, Filip ; Šoustek, Petr (referee) ; Kůdela, Jakub (advisor)
This master’s thesis is about optimal route planning for electric vehicles. The first, theoretical part of this work introduces the issue and describes several heuristic methods that have been used to address optimization tasks. A practical part of the thesis is based around software implementation of the methods described earlier. Finally, several experiments and comparisons of obtained results are carried out.

Postal robot navigation
Jež, Radek ; Richter, Miloslav (referee) ; Janáková, Ilona (advisor)
This work deals with algorithms for postal robot control. It solves problems with finding shortest path and possible problems incurred during navigation of robot. Work includes description of used data structures and algorithms for autonomous activity. Next includes description of user interface of main control application and two supplement applications. Sequel is description of testing work in real environment and evaluation of results. At the end there are summarized information followed from testing and recommendations for next testing.

Cellular Network Coverage Model
Unzeitig, Lubomír ; Mikulka, Jan (referee) ; Gleissner, Filip (advisor)
This work deals with a mobile signal propagation in electromagnetic wave form in a real environment of city microcell. The electromagnetic wave passing through the city environment is affected by many kinds of mechanism. It includes especially diffraction along vertical edges of buildings, diffraction across building roofs and buildings or ground refraction. These mechanisms are time variable. If we want to predicate them, we have to use sort of approached model. For an experimental part of this work, the Berg’s recursive model with a possibility of path loses or signal level prediction in a selected microcellular system is chosen. The software for a cellular network coverage is created on the basis of this fact. Its advantage is a possibility of up to five base stations placing and many kinds of settings, e.g. operating frequency, base station transmitting power, base and mobile station antennas height etc. There is a possibility of system GSM 900, GSM 1800 or UMTS choice. The Berg’s recursive model features are checked by simulations on experimental and real maps of build-up area.

Multi-shuttle control system
Surový, Roman ; Říha, Kamil (referee) ; Přinosil, Jiří (advisor)
The aim of this work is the design of a partial concept and technical solution for the control system of carts that move within the racking system both horizontally and vertically. It is mainly about solving the problem of communication between individual trucks and planning the optimal route with safety in mind. The proposed system is implemented and verified in laboratory conditions. As part of the diploma’s work, the overall concept of the system is designed, the proposed method of intercar communication and verified in laboratory conditions.
