The study of the hand-operated compaction vibratory equipments
Tirala, David ; Škopán, Miroslav (referee) ; Kašpárek, Jaroslav (advisor)
This thesis is focused on an overview of handheld vibratory compaction equipment. The analysis includes a clean distribution, design description, description of compaction technology, technical and operational parameters of commercially available machines for each category of handheld vibratory compaction equipment. Final part of the thesis is dedicated to assumptions in further direction of this field. Collected data of commercially available machines is summarized in tabular form.

Testing and evaluation of ceramic core properties for investment casting technology
Tirala, David ; Krutiš, Vladimír (referee) ; Kaňa, Václav (advisor)
Production of top quality castings for applications in energy, aerospace and medical industries by the addition of ceramic cores to investment casting presents many metallurgical and technological problems. Ceramic cores applied in investment casting are subjects to many requirements in terms of their inertness to the casted alloy and at the same time to their final removal from the casting cavity in such a way that does not damage the casting. Both of these assumptions can be achieved by applying a thin layer of inert oxide ceramic coating to the surface of a ceramic core, made out of a chemically removable – leachable oxide ceramic.
