Aircraft air-conditioning systems
Lednický, Ondřej ; Horák, Marek (referee) ; Třetina, Karel (advisor)
The bachelor thesis is focused on the aircraft air-conditioning systems, their functions and basic tasks needed for a safe and comfortable flight. The thesis is divided into several chapters: the first one deals with the most important factors influencing human health. Next chapter is focused on a description of the assurance of main components which are composing the aircraft air-conditioning system. Final chapter of the thesis deals with oxygen systems, which are essential for the survivor of the passengers in the case of an accident.

Design of certification static strength tests of the aircraft UL category
Serediuk, Vadym ; Horák, Marek (referee) ; Jebáček, Ivo (advisor)
The diploma thesis involves the design of certification static strength tests for the newly developed aircraft of the TL-Ultralight company. At the beginning of the work, the theory of aircraft testing is generally discussed with emphasis on static strength tests. Furthermore, an analysis of the requirements of the Czech regulation UL 2 and the German LTF-UL, which represent the certification basis for this aircraft, is performed. The requirements of regulations on the construction of the aircraft (or its individual parts) and the requirements for strength tests are discussed in detail. Based on the regulation and the provided calculation protocols, individual test cases and test plans of the wing, tail surfaces, engine bed, and chassis are calculated and prepared. In the end, the calculation of the rocker system and the basic design of jigs are performed.

Construction of equipment for thin walled L-profiles instability testing
Polčák, Marek ; Vaněk, František (referee) ; Horák, Marek (advisor)
Bachelor’s thesis deals with the loss of stability of axially loaded thin-walled aluminium profi-les, which make up an important part in the aircraft structures. The loss of their stability is tes-ted by the compression test, which is used to determine the buckling load. Compression test may be influenced by many factors, which are related to the fixing to the testing machine. The aim of the thesis is to design a fixture, which would fix a specimen to the testing machine and improve the results of the test.

Air transport helicopters
Rybka, Slavomír ; Horák, Marek (referee) ; Nastálek, Ondřej (advisor)
The Bachelor thesis contains introduction of the helicopter techniques from the beginning of their development to the present. The work includes complex view on the types of the transport helicopters based on their characteristic elements of design. The machines are devided according the number and location of the rotor, the method of dealing with reaction torque, engine type, the type of rotor heads and take-off weight. There is an overview of selected types of categories for each group, too. The work also includes profiles of selected companies which provide services related to helicopter transport in the Czech and Slovak Republic, including pricing list of services they offer.

Power line communication modelling in Network Simulator-3
Horák, Martin ; Zeman, Václav (referee) ; Mlýnek, Petr (advisor)
The diploma thesis deals with the issue of data transmission over power lines, focusing on simulation transmission functions. The theoretical part summarizes basic information on PLC technology and distribution networks, followed by analysis PLC simulator implemented in NS-third In the practical part of the thesis is described implementation of individual types of underground and overhead lines to the PLC simulator. Also been carried simulation scenarios for a simple topology and were designed own simulation scenarios for extended topology and simulations have been carried out various kinds of interference on communication.

Aggregation and Analysis of Social Network Contents
Horák, Matěj ; Kolář, Dušan (referee) ; Burget, Radek (advisor)
Tato práce se zabývá ziskem zvolené části obsahu sociálních sítí a jeho následnou analýzou. Cílem práce je platforma propojující jednotlivé sociální sítě, která dokáže agregovat obsah těchto sítí podle definovaných témat a zároveň je otevřená dalším rozšířením. Tento cíl byl vyřešen pomocí kontejnerové aplikace, štítkové klasifikace a metody podpůrných vektorů. Implementovaný systém řeší algoritmem nezobrazovaný obsah, filtrování a menší statistiky. Klíčové části systému jsou pokryté testy a systém je otevřený dalším analýzám a pokročilým statistikám.
