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.

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.

Static analysis of a concrete outlet channel
Skalník, Stanislav ; Nováček, Jan (referee) ; Zich, Miloš (advisor)
The thesis deals with the static analysis associated with the outlet channel of the lock chamber. The basis for the work was the design of reinforcement using full-threaded prestressing bars and the drawing documentation of the existing condition. The aim of the work was to present the issues associated with the anchoring of the prestressing bars by cohesion in the existing concrete structure, in particular testing on test blocks in the laboratory to verify a suitable solution. Following the data obtained, to perform an analysis and comparison on models solved by nonlinear computation in ATENA Science software. Subsequently, the analysis of the model of the existing condition of the outlet channel section is also carried out by nonlinear calculation with the evaluation of its behaviour to extreme loads. This model is then supplemented with reinforcement using prestressing bars with application of the knowledge associated with the pullout test models. The model of the pre-stressed outlet channel section is thus a simulation of the design on the lock itself.

Aging curves of elements of the distribution network
Bočan, Tomáš ; Malínský, Vladimír (referee) ; Ptáček, Michal (advisor)
The bachelor thesis deals with the evaluation of the current methodology, provided by the client EG.D, a.s., for the creation of aging curves of distribution system elements, specifically the evaluation of the provided input data, from which a new methodology is subsequently created. The new methodology is applied to the high voltage support points and compared with the original methodology. The paper also includes an analysis of the ageing of distribution system elements and its application to each regional distribution network operator, as an important illustrative and general overview to better understand the individual context.

Critical Parameters for Wireless Networks WiFi and WiMAX
Grenar, Milan ; Křepelka, Václav (referee) ; Baroňák, Ivan (referee) ; Filka, Miloslav (advisor)
My thesis will be aimed at problems of wireless networks WiFi and WiMAX. A modelling of network will be put into effect onto which the measurement will be implemented and the impacts of network load on the data transfer Quality of Service (QoS) will be examined with aiming at VoIP. On this network model a power failure will be simulated and the impacts of this failure after restoring the power supply will be monitored. The aim of this thesis is to check the rate of network throughput while preserving a providing service quality and to suggest an economica1ly acceptable solution of the problems relating to feeding tension outage of the access point (AP) for a practical usage in these networks.

Diagnostics of the bridge structure
Wünsche, Dominik ; Cikrle, Petr (referee) ; Kocáb, Dalibor (advisor)
The diploma thesis deals with the issue of bridge strustures, especially their diagnostics and evaluation. The work consists of two parts, theoretical and practical. The theoretical part deals with the basic description and division of bridge structures, brigde inspections and test methods, especially those that were used in the thesis during bridge inspections. The practical part includes a visual inspection of two bridges, their description, detection of faults and defects and their documentation. In the practical part, the basic maretial characteristics of concrete bridges were determined, the condition of structures was assessed and a proposal for the elimination of failures and defects was developed. In the end, the work deals with the evaluation of both bridges.

Reduction residential property prices as a result of defects or faults assessed construction
Kouřilová, Markéta ; Superatová, Alena (referee) ; Weigel, Lubomír (advisor)
This thesis has the task to bring us to the issue of the valuation of the house loaded defect perimeter walls. The first chapter focuses on the theoretical information in the issue of property valuation. The second chapter deals with possible defects and faults of real estate. The third chapter is to approach the issue of property damage. The fourth chapter provides a survey of real estate and the last, fifth, chapter focuses on a case study of the valuation of the house with impaired peripheral walls and the suggestion of possible ways how to reduce the value of the property as a result of the defect.

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.

Survey and Diagnostics of Building Construction
Černý, Jan ; Komárková, Tereza (referee) ; Anton, Ondřej (advisor)
This bachelor thesis deals with the issue of diagnostic exploration of the railway vault bridge on the track section 2201 Nezamyslice - Olomouc hl. n., a registration kilometer of 69,982, also known as the "Vysoká pivínská klenba". In the theoretical part is described the problems and the systematicity of diagnostic methods for masonry structures. The practical part focuses on the processing and evaluation of the diagnostic survey, which results in determining the material properties of the structural elements.
