Process a review of the specified electrical equipment
Lanc, Rudolf ; Mach, Martin (referee) ; Veselka, František (advisor)
The revision of the electrical equipment means verifying the state of the equipment concerning its safety. The aim of the Bachelor Thesis is the revision of the selected electrical equipment. The particular equipment will undergo a revision, measurements, supervisions, and tests, which are subject of the norms. A revision report will be issued as a result of the established facts, in which possible failures will be described. Further on eventual risks will be explained and techniques how to eliminate them proposed.

Specifics of assessment of old concrete structures
Mička, Michal ; Žítt, Petr (referee) ; Cikrle, Petr (advisor)
The bachelor thesis deals with evaluation of properties materials concrete structures of former textile factory Vlněna from the 19th century in Brno. The content of this work is divided into the theoretical and practical part. The theoretical part deals with the description of the methods used in the research of reinforced concrete structures, comparison of the types of beams used in the past with used today and unlike the principles of the design of reinforced concrete structures in the 1920s and 30s of the 20th century compared to the present time. There are also described components, properties and technologies of concrete production in the period between the war and the comparison with the present time. The practical part consists of on-site examinations and sampling. A large part consists of the evaluation of laboratory tests on the test samples taken from the solved part. A total of 24 test samples were performed. It also compares the strength of the concrete reinforcement with the reinforcement used today.

Optimization of Hydraulic System and its Components for Commuter Category Airplanes
Kameník, Luboš ; Rousek, Miroslav (referee) ; Hlinka, Jiří (referee) ; Třetina, Karel (advisor)
The dissertation thesis deals with optimization of the selected areas of the hydraulic system for small and medium transport aircrafts. Newly developed small aircraft EV-55 is a representative in the category of the small aircrafts . The selected areas of the hydraulic systems , important and useful for domestic producers of the hydraulic devices and whole hydraulic systems for the airplane EV-55 , are subjected to optimization efforts in the dissertation thesis. Design parameters of the hydraulic system (type of hydraulic source, level of pressure, weight of connecting tube), hydraulic devices ( tribology, machining process), simulation of the servomechanism and areas of diagnostic of technical status of the hydraulic system are optimized in the dissertation thesis.

Evaluation of stone column defects using an ultrasonic method
Kršková, Šárka ; Kocáb, Dalibor (referee) ; Cikrle, Petr (advisor)
This Bachelor thesis deals with evaluation of structure defects in stone column using ultrasonic method. Content of this thesis is divided to theoretical and practical part. Aim of theoretical part is to explain process of evaluation of existing stone structures according to norm ČSN ISO 13822. This part also contains listings of method for stone testing and brief explanation of chosen types of rock used for stone structures. Practical part contains tests used on columns using ultrasonic method and laboratory tests of chosen samples. Evaluation of measuring using ultrasonic method is based on knowledge of this method and visual inspection of columns. In laboratory tests were compared results of chosen properties on examples of same type of rock. These examples had different shape, moisture and measurement.

Comparison of assessment of the state of bridges in Germany and the Czech Republic
Víša, Ondřej ; Stehlík, Michal (referee) ; Cikrle, Petr (advisor)
With the increasing age, amount and demands on the quality of bridges, the role of assessing their condition is increasingly important both in the Czech Republic and in Germany. This bachelor thesis compares the general state of bridges in both countries in its theoretical part; furthermore it compares the standards, terminology, the way of keeping record and evaluation. The practical part is reserved for survey and assessment of a bridge in Germany and for comparison purposes also in the Czech Republic. In its end the thesis summarizes the most fundamental differences between Czech and German methods.

Non-destructive inspection methods of aircraft selected parts
Kníř, Jakub ; Třetina, Karel (referee) ; Trefilová, Helena (advisor)
Non-destructive testing (NDT) is a broad scientific field. This bachelor thesis provides an insight into NDT’s methods. It can’t embrace the whole field in any case because it’s needed to have knowledge from variety of other scientific fields in order to understand NDT completely. This thesis outlines basic testing methods and their usage for particular components of aircrafts. The thesis also includes a list of Czech and European standards relevant to the topic.
