Functional Hazard Assessment (FHA) of 4-seat aircraft
Jakl, Jan ; Weisman, Andrej (referee) ; Hlinka, Jiří (advisor)
At the beginning this master's thesis includes of a comprehensive review of aircraft accidents in this category, 2-6-digit aircraft for passenger transport. Since this work focused on autopilot, so naturally there is a basic overview of most common autopilots, which can be found in these aircraft now, but in the future. Functional hazard analysis (FHA) for the 4-seater plane for passenger services primarily investigates cases of catastrophic malfunction, which in most cases accompanied by the likelihood taken from different databases. The airplane, which is created for this analysis will preferably equipped with instruments for IFR flights. There is also a brief overview of the regulations necessary for the installation of these systems in the airplane. At the end of this work is to design the dashboard, a design layout of equipment for future aircraft, with an emphasis on maximum transparency.

Risk analysis in conformity assesment process
Možný, Radek ; Teš, Vasilij (referee) ; Koška, Petr (advisor)
When presenting a product within the so-called regulated sphere the producer is obliged to keep to the given legal liabilities of the technical product requirements and the governmental regulations concerned. The producer is also to carry out an analysis of the technical requirements and specifications of the product. Subsequently, the producer also has to provide the technical specifications and documentation for preparation of ES declaration, guaranteeing that the product fulfills the CE requirements. The task is to design and set up documentation for the ES declaration for Polymount printer cleaning machines PPC mini, PPC M2, PPC L2 and PPC XL2.

Design of aircraft power unit
Poledno, Martin ; Maňas, Pavel (referee) ; Nevrlý, Josef (advisor)
This diploma thesis deals with basic design and calculation of an aircraft power unit (APU). For desired shaft power the thermal cycle is calculated. Basic dimensions of compressor, turbine and exhaust system are calculated as well as thermodynamic parameters of air and hot gases along the motor. Corresponding compressor map, turbine map and characteristics of the exhaust system are designed. Based on these characteristics, an effective shaft power is being calculated in various off-design conditions. Dependency of the shaft power vs. altitude is also presented. All the calculations are made in MATLAB. Finally, simplified motor cross-section is created.

Modal Properties of 4-cylinder Tractor Engine Powertrain
Ehrenberger, Pavel ; Beran, Martin (referee) ; Dundálek, Radim (advisor)
This diploma thesis contains a summary of the general information about the torsion vibration of the crankshaft. The main task is to prepare a flexible model of the crankshaft in the FEM program ANSYS and the subsequent export into the MBS ADAMS / Engine. According to parameters the model of four-cylinder line tractor engine with flexible crankshaft is built. Crank mechanism is analyzed to determine the natural frequencies and natural modes. Finally the results are evaluated and compared with analytical calculations.

Solar cell non-destructive analysis
Černý, Michal ; Škarvada, Pavel (referee) ; Macků, Robert (advisor)
This thesis briefly analyse contemporary situation of photovoltaic systems and their actual developemenet. It shows a typical properties of most produced up-to-date types. Decision point of this thesis consist in nondestructive analyse of monocristalic unijunction solar cells. It describes two main diagnostic aproaches. First – through the use of measuring of VA characteristics, second – through the use of measuring noise characteristics. With selected samples are performed experimental measurements and estabilished basic parameters. In case of drone analysis considerably attention is devoted to experimental equipment for automatized measuring of spectral power density. This experimental equipment is consequently used for measuring some samples where we can observe microplazmatic noise.

MES systems
Štrublíková, Iva ; Kantor, Tomáš (referee) ; Simeonov, Simeon (advisor)
The content of the diploma thesis is a description of the functions and features of the production control systems - MES (manufacturing execution systems), an analysis of these systems implemented in The Czech Republic, an elaboration of the system proposal of an intelligent production control system and retrieving new algorithms and functions according to which these systems can by formed. The MES systems analysis is performed by comparing implemented systems to the modules of production control systems conformably to MESA international. In the system suggestion there will be the intelligent component formed by automatic analysis of the effect of the order delay in production - automatic Gantt chart comparison of the plan versus reality. According to the adjusted system parameters it will separately make decisions about production scheduling. Searching new algorithms and functions will proceed in the reagions of artificial intelligence - genetic algorithms, holonic and multiagent systems, experts systems.

Bus transport process analysis
Růčka, Josef ; Holubář, Oldřich (referee) ; Fiala, Alois (advisor)
The diploma dissertation deals with the bus transport process analysis. More specifically, it deals with a proposition of the reclamation subprocess control. The dissertation contains the description of subprocess of the main process of bus transport. Moreover, it contains the analysis of the original state of the reclamation subprocess control and a set of measures and recommendations that lead to the more effective evaluation of this subprocess.

Analysis of forging disagreement
Novotný, Karel ; Hoza, Jiří (referee) ; Fiala, Alois (advisor)
This diploma thesis deals with the generation of the different drope stampings in industrial process in MBNS Kovárna Company. The main purpose of this thesis is analysis of the industrial process and finding the main factors influences on the process. It especially deals with forgings of the shafts and also flanges with the similar quality of material 42CrMo4. Reasons of the disagreements are focused on surface insensibilities of the forging - crack. First theoretic part introduces company, meaning of the quality of material and describes tools used for finding reasons of the generation of disagreements. In the second practical part is described the whole industrial process and determination of the reasons of disagreements. In concluding part the results are analyzed and some correctional recommendations are suggested.
