BYSTŘICKÝ, Radek. Dynamic system mathematical model of UAV helicopter. (in Czech). [Ph.D. Thesis]. Brno : University of Defence, Faculty of Military Technology, 2009. 129 pp. Supervisor: doc. Ing. Rudolf Jalovecký, CSc.
Thesis deals with four major areas. The first passage is devoted to the technical problems of design and construction of the onboard measurement unit. The second area is the mathematical method used to obtain flight and navigation data needed for the identification techniques implementation of a dynamic system. The third area deals with the issue of identification of dynamic coefficients of a helicopter. Using the methods of identification is then created a mathematical model of helicopter. The last area is devoted to adjusting the dynamic properties of a mathematical model, especially the increase in helicopter stability. |

KALLAB, David. Metrological support information system of the Czech Armed Forces (in Czech). [Ph.D. Thesis]. Brno : University of Defence, Faculty of Military Technology, 2009. 70 pp. Supervisor: Col. doc. Ing. Miloš Andrle, CSc.
This thesis deals with the issue of the Army of the Czech Republic Metrology support (MS) information system. Based on a theoretical analysis of information requirements of the individual elements of the MS system, suggestions have been made concerning its primary functions, including basic data structures. The thesis is aimed mainly at encompassing the specifics of keeping metrological files and records, generating planning and calibration requirements, order management by the metrological executive element and the possibilities of evaluating the effectiveness of processed tasks. The thesis also contains a theoretical planning model described in detail, which enables an increase in effectiveness of the planning process and thus an increase of its objectivity. A theoretical model of the order flow management was implemented into a commercial software MESS and tested continually for more than two years in a daily routine of a metrological laboratory. Although the thesis deals with these issues at a theoretical level, practical results of implementing the order flow model and the evaluation of the effectiveness of metrological executive elements are also provided. |

JEŘÁBEK, Jaroslav. Operation efficiency analysis of aviation electronic support facilities (in Czech). [Ph.D. Thesis]. Brno : University of Defence, Faculty of Military Technology, 2007. 113 pp. Supervisor: doc. Ing. Karel Třetina, CSc.
The dissertation thesis is worked by theme "Analysis operation efficiency aviation electronic support facilities". The thesis deals with possibility plotting operational-economic characteristics aviation electronic support facilities. Further method of economic analyses (LCC, unitary load and CBA) to plotting economic effectiveness its operation arte introduced. Last but not least submitted ideological proposal of information system which collects mentioned operational economic data and exploitation designed mathematical statistical and economic apparatus. In the end is functionality suggested information system verification by experimental processing and evaluation real data. Keynote of the thesis is propriety designed information system on one's behalf work commanders and subject specialists markedly improving their driving planning and checks activities in aviation electronic support branch. |

KOUKOL, Ondřej. COTS (Commercial/Cost-Off-The-Shelf) data buses analysis and methodology of their certification for use in aeronautics (in Czech). [Ph.D. Thesis]. Brno : University of Defence, Faculty of Military Technology, 2007. 64 pp. Supervisor: doc. Ing. Rudolf Jalovecký, CSc.
This dissertation deals with problems of commercial data buses from COTS (Commercial/Cost Of The Shelf) area which used in aerospace industry. It evaluates current situation of this problem including fundamental description of used solutions and related legislation. The next part of document is a proposal of certification methodology for such of data busses which should be used for these processes. This proposal is based on practical experiences and cooperation with Civil Aviation Authority Czech Republic (CAA) and Federal Aviation Administration (FAA). As a representative of these commercial solutions we selected data bus Controller Area Network (CAN). In practical part, we evaluated according to this methodology it’s usage within aerospace industry and made laboratory and others verification of its characteristics. This work was made on System of Avionics Modules (SAM) which is implemented into the Ae 270 aircraft. |

GRECMAN, Pavel. Mode-S positional data error analysis from the point of view of Air Traffic Control (in Czech). [Ph.D. Thesis]. Brno : University of Defence, Faculty of Military Technology, 2005. 108 pp. Supervisor: doc. Ing. Beer František, CSc.
This thesis deals with theoretical approach to static and dynamic positional errors evaluation. It also contains real measurement and evaluation of positional errors from mode S squitter. The results of analysis are expressed in graphical representation of Ellipse Error Probable (E2EP) for 2D and Ellipsoid Error Probable (E3EP) for 3D which enable more precise representation and computation of positional errors. DGPS receiver is used as reference system when evaluating dynamic positional errors. |

DUB, Michal. Optimalizace spínací frekvence při PWM řízení stejnosměrných elektromotorů pomocí čtyřkvadrantového měniče. [Disertační práce]. Brno: Univerzita obrany, Fakulta vojenských technologií, 2005. 69 s. Školitel: doc. Ing. Rudolf Jalovecký, CSc.
Disertační práce řeší otázku optimalizace hodnoty spínací frekvence při čtyřkvadrantovém PWM řízení stejnosměrných elektromotorů s cizím buzením. Optimalizační úloha spínací frekvence je charakterizována více než jednou účelovou funkcí spínací frekvence, proto je k jejímu řešení užito metody vícekriteriálního programování. Nejprve jsou vytvořeny frekvenčně závislé omezující podmínky a kriteriální funkce a poté následuje řešení optimalizační úlohy pomocí metody globální cílové funkce.. |

VAŠEK, Milan. Příspěvek k zvýšení bezpečnosti letového provozu aplikací metod prognózování pro stanovení odborných požadavků na lidský faktor v systémech CNS/ATM. [Disertační práce]. Brno: Univerzita obrany, Fakulta vojenských technologií, 2005. 142 s. Školitel: doc. Ing. Miroslav Janošek, CSc.
Disertační práce se zabývá problematikou lidského faktoru v letectví z hlediska technického personálu v systémech CNS/ATM. Důraz je položen na člověka operátora a jeho odborné znalosti mající vliv na bezpečnost letového provozu. Pro stanovení skladby a množství odborných znalostí je použita expertní prognostická metoda Delfy. Je zde uveden metodický postup, základní matematický aparát a výsledky statistického vyhodnocení. |
