Internet Connection variants using present TV cable wiring
Lukáč, Michal ; Martinásek, Zdeněk (referee) ; Stančík, Peter (advisor)
This dissertation examines data transfers along the existing lines of cable TV. PLC equipment has been selected as the focus of this examination. The essay examines the question of Multicarrier modulation and focuses more specifically onto the problem of OFDM modulation, which is being used by the selected equipment. It further describes the process of integration of PLC equipment into the cable TV network, modifications of the CATV and the basic topology of the created data networks. The essay also offers a closer look onto a PLC modem and Head End from Corinex that have been used in the implementation of a data network in a selected rural settlement. The author has also raised the issue of the problems connected with cable wires connected with this particular type of data transfers and the solutions of some of the encountered problems. The characteristics of this network have then been measured during normal operation of the created network. Measurements have been carried out in order to determine the transfer speed on a physical and transfer level, the SNR of specific connections and the signal attenuation. The measurements have confirmed the suitability of the used PLC equipment for the purposes of data transfer along the cable TV lines as far as data speed and signal strength was concerned. A map of the particular cable TV lines and the PLC equipment has been included in the attachment.

Automatic Image Labelling
Lukáč, Michal ; Řezníček, Ivo (referee) ; Hradiš, Michal (advisor)
This thesis focuses on automatic image labelling to semantic categories. It describes the theory of classif cation and local features detection. It explains fundamental machine learning models used for image tagging, and how such models can be learned with Gradient descent. It propose solution with hierarchy for ImageNet and tagging images with attributes. MapReduce computing model is considered for learning on big data sets. In the last part it is described implementation, experimental and test results.

Influence of Advertising on Real Estate Buying Decisions
Vrlová, Iva ; Lukáč, Michal (referee) ; Barňák, Tomáš (advisor)
The work deals with the development of advertising and marketing channels used by real estate agency on the Czech real estate market. Detailed phase defines the different types of advertisings and actors entering in the real estate market, as between sellers and buyers than among the intermediaries as well. If the real estate agency want to apply or increase sales through certain advertising, is the task of this work determine which target groups to use for specific kind of advertising.

Risk management in the Company Technické služby Jeseník a.s.
Lukáč, Michal ; Štěpánková, Vladěna (referee) ; Janíček, Přemysl (advisor)
This diploma thesis deals with the risk management issue of a projection of regional aqua-park Jeseník, with the aim to identify risks connected with realization of this project. This particular process of risk management adjustment is isolated proceeding with its characteristics, and expertise, with replenishing purpose of project management awareness for possible risks, and their impacts on the project and its surroundings. Using a system approach and risk management weaknesses, which are the most threatening for the project as well as financial formulation of particular risks, are identified. Attending matters of risks, strategies, which will be used for the utmost elimination of doubts from the realization, emerged. Proposals and disposals refer to advantages, and urgency of applying risk management processes along with system thinking for management, which corresponds with the particular project.
