Hodnocení kvality pomocí nedestruktivních technologií
Ševčík, Michal
The diploma thesis titled "Quality assessment by non-destructive technologies" is focused at evaluation degradation qualities of welded components, which are material heterogeneous. Welded samples are made for experimental measuring by CMT method and their degradation qualities are measured by the acoustic emission during the corrosion process and tensile straining. The theoretical part is aimed at on basic division most used method NDT, the main stress is on AE. Te final part is focused on corrosion engineering, especially on problematic galvanic corrosion, which is important in case of interaction of homogenous materials. Material samples which were used are mentioned at the beginning of experimental part. Then the thesis is dedicated to summary of methods used during the measurement. The next chapter provides courses and exp. results of observations and measurements using AE. Courses and exp. results of observations and measurements using AE are in the last chapter.

Ultrasound in material diagnostics
Kristek, Michal ; Frk, Martin (referee) ; Kazelle, Jiří (advisor)
Objectives of the semestral project are to study the physical basis of ultra acoustic and comprehend the basics of ultrasound usage in diagnostic of materials. I should also become familiar with functions and usage of ultrasound device EPOCH LT made by OLYMPUS and perform measurement of thickness and speed of ultrasound spreading in selected materials.

Survey and Diagnostics of Building Construction
Resl, Jaroslav ; Cikrle, Petr (referee) ; Anton, Ondřej (advisor)
The thesis is focused on the overview of the diagnostic methods for engineering surveys reinforced concrete constructions. The practical part explains engineering surveys of industrial building, evaluation of concrete strength on existing building and results from search reinforcements on individual elements. Next part is focused on load testing precast floor slab removed from construction and evaluation load capacity. The last part include structural design of elected parts (precast floor slab and beam).

3D Scene Reconstruction from Images
Fuchsík, Ondřej ; Zahrádka, Jiří (referee) ; Španěl, Michal (advisor)
This bachelor thesis deals with scene reconstruction from images using RGB--D senzo Microsoft Kinect. The aim of the work is to create model of the room in form of points from scanned data, from witch is created plan of the interior. A large part of the work deals with the point cloud registration, thus existing methods and their descriptions. Further, a projection of points on a plane and detection of edges in the obtained image are discussed. The work experimentally examines the influence of recording and the recorded environment on results.

Intelligent Control Methods in Automation of Process of Construction Machines Control
Vaverka, Michal ; Škopán, Miroslav (advisor)
This work deals with the possibility of use of intelligent methods in construction machines control. These methods are based on GPS in combination with using laser and ultrasonic technology. There is in detail described especially control by robotic total station and 3D control, which includes digital model of construction site. The new trends of control are especially applied on the vibratory rollers. There are taken into consideration: achievement of sufficient degree of compaction on the basis of on-line information about conditions of subsoil.

Diagnosis of metallic materials
Buday, Matej ; Šedivá, Soňa (referee) ; Bejček, Ludvík (advisor)
This thesis deals with non-destructive testing (NDT). It Describes two basic thermographic methods, lock-in and pulse thermography. Different types of measurements using Fluke Ti55, points to the possibility of applying these methods in practice. Pulse thermography issue is a substantial part of this work, due to its good applicability. Also, it compares visual testing methods (VIS) and pulse thermography due to measurement with die-casting alloy AC-AlSi9Cu3 (Fe).

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.

Diagnostics of ceiling structures - possibilities of using GPR
Resl, Jaroslav ; Heřmánková, Věra (referee) ; Anton, Ondřej (advisor)
The thesis is focused on the overview of the diagnostic methods for engineering surveys. The distribution of ceiling structures according to various parameters is described. The theoretical part then provides an analysis of diagnostic methods for the ceiling structures in more detail. It includes a description of the operating principles of GPR. The practical part explains the construction and technical survey of ceiling structures using ground penetrating radar as well as measuring on a physical model. Practical measurement is focused on the use and limitations of the radar.
