Supply chain for the construction company
MAZANEC, Tomáš
This graduation thesis occupies by logistics utilization in the construction company Baracom Inc. It tries to describe the areas of the civil engineering which the logistics can be used in. The emphasis is placed on the supply network and on the whole project management from the beginning to the customer delivery. The concrete apartment blocks development is analysed from the building land purchase to the complete constructions. What is desribed here is e.g. the selection of the suppliers, the creation and the adherence to the schedules... The supplier evaluation in the company and the flow of material at the construction were also analysed out. The advantages of the wooden constructions were presented. The effort was to explain the low-energy constructions´ benefits and their potential in the future.

Simulátor fyzické vrstvy ADSL
Mazanec, Tomáš
This paper presents simulation results accomplished within ADSL toolbox, which was developed in our institute. The toolbox simulates physical layer of ADSL communication chain, where the main efforts are given to equalization techniques at receiver, proper channel partitioning at transmitter and channel modeling.

ADSL - equalization techniques
Mazanec, Tomáš ; Heřmánek, Antonín
The work presents the state of the art in digital signal processing in ADSL physical layer. Mainly, the equalization techniques are studed. The basic and advanced equalization algorithms are presented (both in time and frequency domain) and their characteristics are discussed.

Pokročilé algoritmy pro ekvalizaci ADSL kanálu
Mazanec, Tomáš
Digital subscriber line modems equalize response of line (channel) to fight with interferences and line dispersion which down the bit-rate of transmission. Main equalization principle is “Channel shortening” which is the base for time domain equalizers (TEQ). Many TEQ algorithms have been already proposed, mainly in theoretical sense. With growth of hardware performance, more complex methods can be applied in practice. Thus a proper simulations and fast implementations are necessary to achieve this. We developed a toolbox which implements some simple and advanced time domain equalization algorithms and simulates ADSL transmission line with reference channels (loops). This paper introduces implementation details and comparison of selected equalization algorithms.

Model přenosového systému záchranářského robotu Orpheus
Mazanec, Tomáš ; Heřmánek, Antonín ; Matoušek, Rudolf
The robotic platform Orpheus is a top-class reconnaissance system controlled by an innovative technology called telepresence.The transmissions system of the robot is very critical part, because it must provide short robot response time, while serving wide band video signal to the operator. Wi-Fi technology can handle both parameters, but it struggles with poor reliability in situations without line of sight between the robot and the operator's transmitter antenna. An article deals with a model in Matlab.
