Detection of Failures and cavities in structures using radar
Tkadleček, Petr ; Anton, Ondřej (referee) ; Cikrle, Petr (advisor)
The bachelor‘s thesis describes non-destructive testing and methods, which are used in civil engineering. It is focused on the detection of failures and cavities in concrete structures. In the first part the methods are described and compared. The second part describes experimental measurements on concrete structures, which contain failures. The results are described and interpreted. The used methods are compared. It was evaluated, which of these methods is suitable for the detection of failures and cavities in structures.

Monitoring of partial discharges and their minimization in switchgear UG ZS1
Bajánek, Tomáš ; Bernard, Michal (referee) ; Lázničková, Ilona (advisor)
Bachelor's thesis deals with partial discharges which occur in switchgear ABB UniGear ZS1. The work deals with the theoretical analysis of partial discharge, a description of the parameters and possibilities of measuring partial discharges. It deals with the description of switchgear as an electrical equipment and analysis of the places where it may lead to formation of partial discharges. The work contains a description of the laboratory for measurement of partial discharges in the company ABB, description of measuring equipment LDS-6 and basic project of optimization of partial discharges in switchgear ABB UniGear ZS1.

Využití přístrojových metod k hodnocení stavu stromů
Vančurová, Klára
The bachelor thesis is focused on the topic: Use of instrumental methods to evaluate the condition of trees. The first part of the literature review describes the vitality of trees and explains why they are evaluated. Subsequently, the work deals with the division of individual methods and devices into visual and instrumental evaluation. These are then further categorized according to their principle of use.Totaly were evaluated four instrumental methods of physiological vitality and for biomechanical vitality six visual and eighteen instrumental method. In the next part, based on the description of these instrumental methods, an analysis of companies in the Czech Republic was created, which provide measurement and evaluation of expert opinions with these instruments.
