Sensor for low-speed continuous motion sensing
Tomášek, Petr ; Slavík,, Lubomír (referee) ; Fiala, Pavel (advisor)
Diploma thesis analyses low-speed flow measurement. Thesis consist of 4 chapters. First chapter is about liquids and its attributes, flow meters, especially induction flow meter, which is very important for designed sensor. In second chapter is detailed process of designing sensor. Description of realization and measurement of flow is in the third chapter. Result summary is in conclusion.
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.
Non-destructive Detection Methods of Biological Activities Wood-destroying Insects
Kintr, Jindřich ; Král, Bohumil (referee) ; Fiala, Pavel (advisor)
The subject of this thesis is to study a non destructive methods and methodologies of detection biological wood pests. Analyzed method of detection in this thesis is non destructive acoustic detection. For scanning the activity of wood pests a sensor with piezoelectric converter is used and for scanning the ambient sound a sensor with an electret microphone is used. The signals from these sensors are subtracted in a differential amplifier. In this thesis we can find a method determine the similarity of two signals and a laboratory measuring of detection of activity of a wood pests (Hylotrupes bajulus).

Nondestructive methods for detection of hidden fatigue crack in the steel bridge element
Valach, Jaroslav ; Frýba, Ladislav ; Jandejsek, Ivan ; Lesák, Jaroslav ; Vála, Ondřej ; Urushadze, Shota
In this paper we discuss applicability and usability of three non-destructive methods for investigation of fatigue crack propagation in railway bridge structural elements subjected to the repetitive loading. These methods are: an optical method based on the digital image correlation, the active thermography method and the classical x-ray radiographic method.
Non-destructive Testing of Concrete Structures by Laser Vibrometry
Trnka, Jan ; Dvořáková, Pavla ; Veselý, Eduard
The reasearch report deals with non-destructive testing of concrete structures by Laser Vibrometry. The aim of the work was to find pros and cons of an application of laser vibrometry for detection failures in concrete structures.
