Selective gallium nitride thin-film growth on substrates covered by pyrolyzed resist mask
Novák, Tomáš ; Kostelník, Petr (referee) ; Voborný, Stanislav (advisor)
This thesis deals with deposition of GaN thin films and GaN selective growth utilizing pyrolyzed resist masks. Carbon masks were prepared on silicon substrates by electron-beam litography and resist pyrolysis. As a further step, Ga and GaN were deposited on the masked substrates by Moleculer Beam Epitaxy (MBE) method. A selective growth of Ga droplets was achieved. These results were used for preparation of GaN crystallites by pulse deposition. It is also shown that direct MBE deposition of GaN on the masked substrates leads to a selective growth of GaN thin films with GaN film growing only on the areas which are not covered by the carbon mask. The results are explained by enhanced surface diffusion of gallium atoms on the surface of the carbon mask.

Verifikation of machine component strain
Novák, Tomáš ; Dočkal, Aleš (referee) ; Drápela, Miloslav (advisor)
The thesis deals with a comparative analysis of strain of parts using finite element method (FEM) and measurement of the optical system Pontos. Part was used the reflector of Volkswagen Polo. The subject of comparing were the values of deviations optical shield of reflector which excitation random vibration described power spectral density. The thesis presented describes of experimental measurements to obtain the boundary conditions using optical systems. FEM analysis was performed using software ANSYS Workbench 12.

Planning of construction contracts by supplier
Nováková, Jolana ; Novák, Tomáš (referee) ; Nový, Martin (advisor)
This diploma thesis deals with the planning of construction contracts from the perspective of a contractor. In the theoretical section, the basic concepts of project management are explained. Further, the methods and principles used in the management of the construction project of building a complex are described. The practical part contains a particular case where the methods are used to schedule a time during the course of construction and planning of the resources needed for implementation.

Field strength measurement
Novák, Tomáš ; Dřínovský, Jiří (referee) ; Nováček, Zdeněk (advisor)
This thesis is focused on problems of measurement of field intensity especially in short-wave zone of received frequencies. To measure the intensity of electric field, it is necessary to use a suitable antenna whose properties and characteristics/parametres meet best the requirements of this measurement. These requirements are analysed/discussed in the introductory part of this thesis. From these requirements resulted one specific solution which is applicable to this problems. This solution is frame antenna which meets /matches best the requirements of this measurement. Furthermore, a complete suggestion for the frame antenna as well as its calculations were discussed. From individually calculated results graphical functionalities were set together that provided the bases for selection of suitable parameters for frame antenna. Then these bases were verified with similar antenna that was available. In second part of this thesis we modified standard antenna modul RFT FMA11 so that there would be a possibility to use it with any selective microvoltmeter.

The Concept of a Development Center as an Effective Tool of Human Resource Managment
Mucalová, Marcela ; Novák, Tomáš (referee) ; Konečná, Zdeňka (advisor)
This Master’s thesis is concentrating on the creation of a Development Center for the well-established firm TRANSPED-SOC, Ltd., which has branches in different places of the Czech Republic with a view on dispose agent. In this work we can find a written education system in the firm TRANSPED-SOC, Ltd., which is meant to help with the examination of the education of the employees. The main point is the creation of a competent model for a group of dispose agents, individual and group model-situations derived from the model, design and description other methods, a timing schedule for the Development Center and data sheets. The created Development Center is evaluated and written contributions are the results for the firm TRANSPED-SOC, Ltd.

Current distribution on linear antennas
Novák, Tomáš ; Bártík, Hynek (referee) ; Nováček, Zdeněk (advisor)
This work will describe current distribution measurement problems along antenna conductor using a probe (coupling loop), which is attached to selective micro-voltmeter, which will indicate signal level (voltage). The signal level will be used for representing the current distribution. Subsequently, measuring workplace issues from generator to antenna conductor, probe and selective micro-voltmeter, will be discussed. Analysis of voltages of this link-up and additional study will be conducted. Other parameters, which complement this situation, will be calculated from the current distribution. A computer program, which calculates these parameters and speeds up the collected data processing, will be used for this process.

Design of a drived convertible axis for a reflector Laser Tracker
Novák, Tomáš ; Šubrt, Kamil (referee) ; Knobloch, Josef (advisor)
The subject of this bachelor work is a structural design drawing of a drived convertible axis for a reflector belonging to a measuring machine called Laser Tracer. The convertible axis is used to establish the reflector into two positions during the measurements of the geometric accuracy of vertical lathes. The work includes research in the area of possible structural solutions to the given issue, structural design drawing of a drived convertible axis, calculation of the needed torgque for an electric motor and its control suggestion. Complete drawing documentation is a part of this work, as well as a 3D model of the convertible axis.
