Issue of defining construction defects and failures
Šmahel, Milan
Submission of expert reports in litigation concerning the application of discount on previously purchased old real property due to subsequently discovered construction defects and failures led the author to write this contribution. An expert can be given various tasks in the area of this issue, for example, of specifying and determining: whether by the takeover date of real property by a buyer subject properties embodied defects and failures which the buyer had pointed out to a seller. Then, what costs the buyer must spend on removing subject defects and failures, whether defects and failures are caused by a common wear and tear of an object or by something else, and whether and which of the defects and failures originated from an old and worn object. Moreover, whether such wear and tear, with regard to a life span of individual construction components, was common or not and whether (by the takeover date) the objects were suitable for the use and purpose which they were intended (e.g. housing) for. Last but not least, whether it is possible to specify apparent defects and latent defects by discovered defects and failures, to determine price for real property by the sale date, including both determined price according to the price regulation and common price. Simultaneously, the expert can be given the task to express his view on expert reports attached to a file. Both a great number of tasks and a great number of discovered defects and failures mean a big amount of demanding work for experts. It is appropriate to deal with such work systematically right from the beginning so that conducted analyses, final defining of individual pointed defects and failures and final answers are factual, clear and in order. The author’s experience with the issue of dealing with reports in this area is the subject of this contribution.

Identification and assessment of errors in the production line and their prevention
Lopata, Zbyněk ; Tabas, Marek (referee) ; Kotek, Luboš (advisor)
Master´s thesis deals with the identification and evaluation of mistakes on the production line and their prevention. For the purpose I chose FMEA method. Theoretical part contains description of kinds of FMEA and their application. In the following part description and analysis of current state of production process of the product at NORMA Czech, s.r.o. was made. All important information were recorded to FMEA forms and finally measures for the most critical failures were designed.

Diagnostic of System Reliability
Bábek, Tomáš ; Pohl, Jan (referee) ; Havlíková, Marie (advisor)
This thesis is oriented to the reliability theory and diagnostics. It involves brief explanation of terms that exists in a branches of technical devices reliability. The next part contains determining the reliability indexes, calculations of probabilities and statistics for electronic devices. I do mention the different methods of reliability diagnostics. The three most used of them are described. First of them is the reliability block model. By this I describe the serial reliability model, the parallel reliability model and the combination of them. Using this method is the simple way to show how each component affects reliability of the whole system. The second method is FMEA (Failure Mode and Effects Analysis) which is used mostly in the begining of the system designing. The third method is FTA (Fault tree analysis) which is one of the classic deductive methods. The FTA method is a graphical reliability model of a given system. By the end of this thesis, process of calculating the failure probability and the other reliability indexes of a given komponent (preamplifier with operational amplifier) is shown.

Maintenance of Small Transport Aircraft with Application MSG-3 Methodology
Trefilová, Helena ; Třetina, Karel (referee) ; Finda, Jindřich (advisor)
Master’s thesis deals with problems of maintenance of small transport aircraft with application MSG-3 methodology and maintenance plan development. It is aimed at systems and powerplant maintenance. This method is applied on L-410UVP-E20 aircraft. Other parts of this work are assessment of recent situation in maintenance of airplanes, used approaches to maintenance, methods and documentation for maintenance. Last part of this work is practical example of MSG-3 process on assign item and its interpretation.

Diagnostics of flooring failures and defects in the housing and civic construction
Vrtal, Roman ; Žítt, Petr (referee) ; Schmid, Pavel (advisor)
The object of the thesis is a description of preparation process, realization and subsequent treatment of floors based on calcium sulphate, including problems related to the issue. The aim of the work is to closely acquaint the reader with methods used in diagnostics of flooring failures and defects in the housing and civic construction, including practical applications of these methods on real structures. The work also includes experimental analysis of a real floor construction during local load effect.

Business Plan
Schwarcová, Kristína ; Zbyňovský, Róbert (referee) ; Mandelík, Petr (advisor)
For my project I’ve chosen to create a Business Plan for a Crisis Management Consultancy company. To do this I’ve used a limited company and named it Navigator Ltd. In the preceding project I’ve explained all the essential steps needed to create a new company, as well as pointing out the importance of crisis management for various companies on the market. I’ve described the services in detail, compared the competing businesses in the field of crisis management, shown a view of the future and built a personnel infrastructure of the described company. I’ve created a realistic company strategy and planned budgets needed for a smooth start.

Vibrodiagnostics of induction motor
Mašin, Dominik ; Dostál, Lukáš (referee) ; Janda, Marcel (advisor)
This thesis is dealing with measuring and evaluation of vibration signal. Vibration measurement is one of the most important operation for correct and fluent machinery service, not only from economical point of view but also because of security. Status monitoring of electric machine is a key to detect damaged parts and it is giving us an opportunity to avoid unexpected outages and failures in production. My work describes basic concepts and principals of vibration measurement. Asynchronous motor measurement and its evaluation is performed in practical part.

System of Identification Solder Joint Failures
Vejmola, Tomáš ; Řezníček, Michal (referee) ; Šandera, Josef (advisor)
This paper describes the draft and implementation of a system for identifying failures on the soldered joints from already existing system, which is, however, limited by dependence of the operating system of the human factor. The innovated system provides us an automatic testing of soldered joints using a computer, with subsequent processing of data electronically using the corresponding software. The first part is devoted to the theory of the formation of flaws on the soldered joints and to the familiarization with uninnovated system. Subsequently, work continues with the practical part, which introduces us the procedure and implementation of the innovated system for identifying failures on the soldered joints. The final part of this paper is an evaluation of the results and fulfilment of work requirements.
