Purpose of this master thesis is description of base parts of expert system with using Petri nets. Attention is mainly concentrate to knowledge base, way of storing knowledge. Next parts are describing main different between production base knowledge for planning or diagnostic expert system from Petri nets view. In this thesis conditions of using Petri nets and way of interpretation knowledge for inference mechanism in planning and diagnostic expert system are described. Using of high level Petri nets and language describing Petri nets structure and behaviour are demonstrated in next part of this thesis.

The main topic of this diploma thesis is the modeling of nonlinear effects in ultrasonic fields. The work deals with application of finite difference method (FDTD) on the Westervelt equation and the subsequent creation of the model of ultrasonic fields in MATLAB. This thesis also includes theoretical analysis of ultra-acoustic and technical aspects of diagnostic ultrasonography. In addition, this document includes verification of theoretical assumptions by using created model.

This thesis is focused on a firmware for robotic vehicle based on the ARM Cortex-M3 architecture that is running a real-time operating system (RTOS). Theoretical part describes available solutions of embedded RTOS and concrete HW implementation of the robotic vehicle. There is also comparison of the three selected RTOS with their measurements. Result of this thesis is base firmware compounded by a program modules that controls HW parts. There is also a sample PC and firmware application that extends base firmware. This sample application is able to communicate with robotic vehicle, control wheel motion and measure process data.

As part of my master's thesis I have conducted a visual inspection and record failures of bridge roadway at selected highway bridges, roads D47, D3 and D8 and photographic documentation, which is included in Annex. Also I have based on their speeches and documents the results of control tests determine their causes and to propose appropriate repair or maintenance.

The subject of this diploma thesis is the diagnostic survey of the masonry walls and the connecting bridge in the East Moat of Špilberk Castle. The thesis contains theoretical information about survey and diagnostics of building construction and then evaluation of diagnostic methods used for estimation of essential characteristics of masonry structures. In the practical part the diagnostic investigation of Špilberk Castle walls is processed. That includes determination of material characteristics of the studied structure. In the conclusion there is a suggestion of how to eliminate the structural defects found during the survey.

The subject of this thesis is the diagnostic investigation of block A in the object at Rumiště 8, Brno. The work includes theoretical knowledge of technical surveys and diagnostic methods and their evaluation to identify the essential characteristics of masonry and timber structures. In the practical part is the diagnostic investigation processed. Part of the diagnostic investigation is the determination of material characteristics of the structure. At the end of the thesis is an assessment of the structure.

The aim of the master´s thesis is analysis of limits of tail test exercise in practice for certification of dampening quality of wheel hitches of vehicles using virtual simulation. The goal is to create virtual model of front axle of Skoda Roomster 1.4 TDi using program Adams/View, MSC Software and follow-up simulation of tail test of wheel hitch.

This master’s thesis deals with the diagnosis of thermal environment using synthetic skin type sensors. The synthetic skin type sensor is a compact sensor ideal for simulating human skin. The aim is to design and implement such a sensor and test its properties. On the market there are no compact sensors with that kind of abilities and our goal is to design the cheapest, but still viable sensor. Measurement and data processing is implemented using measurement cards and LabVIEW software. The work also contains a design of signal conditioning without the use of measurement cards.

This thesis deals with problems related to heating of hot service water. It focuses on solar water heating, describes individual types of solar panels and summarizes the existing information about solar water heating. It demonstrates actual problems of solar system solution on a specific example of a two-generation family house, where it analyses possibilities of diagnostics and control of such system. It also deals with suggestions of possible expansion of the current solar system.

The aim of this thesis is to design maintenance work for a small transport aircraft. This thesis is focused on an overview of the activities, which are carried out in the maintenance of small transport aircraft with a capacity about fifty passengers. The first part of this thesis is conceived as a theoretical part and summarizes the activities used during maintenance - maintenance methods, a typical part failures, diagnostics, network analysis and equations for the calculating of the cost of maintenance. At the beginning are showed the basic characteristics of selected representatives of this category and regulatory requirements on them. The design of maintenance work is in the second half of the thesis. It includes the visualization of the database that could be used for the maintenance of aircraft and which could be subsequently evaluated. This is a general description of the maintenance work, which ca be performed during the pre-flight inspection, re-inspection for repeated flights, preliminary preparation and periodic maintenance.
