Electric guitar innovation
Blaha, Marek ; Skvaril, Šimon (referee) ; Jirásek, Ondřej (advisor)
The bachelor thesis deals with the innovation of the electric guitar and its timbre when changing different components in the chain. The thesis describes what parts the guitar consists of and how its pickup works. It also deals with the manufacture of these components and their subsequent assembly. The focus is on pickups, bridges and bodies. Each time a component is changed, the spectrum is analyzed. In the end, the final prototype is assembled and compared to the original guitar.

Production of Ductile Iron with Feritic Matrix
Blaha, Marek ; Šupálek, Milan (referee) ; Molliková, Eva (advisor)
This bachelor thesis deals with the properties and production of ductile cast iron with ferritic matrix. Theoretical part is focused on basic information about ductile iron, its chemistry, structure and mechanical properties. The production of ductile iron with ferritic matrix in JMA Hodonín Ltd is described in the next chapter of this thesis. In the experimental part the real cast is described together with its production technology and material. The practical part is concentrated on comparison of chemical composition, structure and mechanical properties of material of cast and keel blocks made of the same melt. Finally the results of experiments are summarized and the arrangements for improving conformity between material of cast and of keel block are suggested.

Optimization of manufacturing of iron castings to reduce the quantity of defects
Blaha, Marek ; Brázda, Zdeněk (referee) ; Juliš, Martin (advisor)
The presented diploma thesis is focused on defects of castings as well as optimization of production with the aim of reducing the number of defective products. The theoretical part is focused on basic information about cast iron and its production, structure and mechanical properties. Another part of this thesis describes the defects of castings and options for non-destructive testing of cast iron castings. In the experimental part are analyzed three sorts of defective casting. Castings for testing were provided by JMA s.r.o. foundry. The summary contains tests results and proposals for optimization of production.
