Diagnostic methodology of timber construction
Zouharová, Kateřina ; Heřmánková, Věra (referee) ; Anton, Ondřej (advisor)
The thesis is focused on the appraisal of a wooden roof construction in reconstructed family house in the village Lomnice. The first part describes the structure and properties of wood, in the next section followed by a description of diagnostic methods. The final chapter is complete diagnostics of wooden roof truss with remediation measures. Rating roof truss was based on a survey of sensory and instrumental methods. In the first part was determined the type of roof truss system. In the next section was researched damage of elements and his causes. Remedial measures were established for each type of damage to the components resist any attack as long as possible.

Diagnostics of prestressed bridge structures
Konderla, Jiří ; Komárková, Tereza (referee) ; Láník, Jaromír (advisor)
The theoretical part of this bachelor thesis focuses on prestressed concrete and problems that are nowadays showing with using prestressed concrete in bridge engineering and on the methods that are used for condition check of this material. Practical part of the thesis is the construction research and diagnostic of the prestressed concrete bridge structure, evaluation and consecutive interpretation of used methods.

Diagnostic methods for the evaluation of the state of timber structures
Dvořáčková, Soňa ; Anton, Ondřej (referee) ; Heřmánková, Věra (advisor)
This Bachelor´s thesis is focused on diagnostics methods which are destructive, semidestructive and non-destructive. Thanks to these methods, we find out features and characteristics of the material. In the thesis, there is performed diagnostic measurement on a wooden beam and comparing of the results from the method of thorn resistance placement and the results from wood strength measured along the grain. At the end of the thesis there are mentioned statistics calculations.

Survey and Diagnostics of Reinforced Concrete Construction
Pokorný, Jakub ; Vítek, Lubomír (referee) ; Anton, Ondřej (advisor)
The thesis Building Investigation and Diagnosis of Reinforced Concrete Structure is focused on analyzing two reinforced concrete bridge structures. It discusses different evaluation surveys and its influence on later evaluation of the bridges. In this thesis there is included static evaluation finding supports at one of reinforced concrete bridges. Practical part is complemented by the necessary theoretical part, which deals with exploring bridges, ways of their implementation, and a summary of the most commonly used diagnostic methods for bridges.

On-line diagnostic monitoring systems for vibration of machines
Cirhanová, Iva ; Prostredník, Daniel (referee) ; Hammer, Miloš (advisor)
The bachelor thesis deals with diagnostic monitoring systems of machine vibration. First of all, a technical diagnosis with a focus on diagnostic methods, means and diagnostic systems is generally described. Special attention is paid to vibrodiagnostics and termodi-agnostics. In the next part of the thesis there are on-line diagnostic monitoring systems, their parameters and their use in technical practice. Emphasis is placed on systems from SKF, ADASH and ifm electronic. The systems are compared and the economic aspect is briefly outlined. In the bachelor thesis is also evaluated.

Inovation of system for electroluminiscence defect detection of solar cells
Lepík, Pavel ; Křivík, Petr (referee) ; Vaněk, Jiří (advisor)
This master thesis analyses the existing methods both practically and theoretically used to detect defected surface area in solar cells. Various methods were used but by using an upgraded CMOS camera without IR filter to implement the electroluminescence method, this has proven to have a very crucial impact on the results. Given the overall results and the acquired information, a procedure with a simple parameter can be setup to carry out the measurements. In addition to this a catalog was formed showing the defects occurring in mono and polycrystalline solar cells.

Diagnostic method of solar cells operating at very low temperatures
Bartoň, Jiří ; Stojan, Radek (referee) ; Veselý, Aleš (advisor)
This work deals with the modern diagnostic methods of defects detection of solar cells. Defects are detected by electroluminescence and photoluminescence methods. The main focus of this work is an innovation workplace for measuring solar cell defects at very low temperatures using photoluminescence. Liquid nitrogen is used to cooling solar cells. By using low temperatures can be detection methods to obtain more objektive results of diagnostic defects.
