Analysis of Material Flow During Cam Forging
Kopečný, Adam ; Lidmila, Zdeněk (referee) ; Řiháček, Jan (advisor)
The diploma thesis deals with the optimization of final position of overlaps on a forged cam. This part is manufactured in Šroubárna Kyjov, spol. s r.o. The cam is made from ČSN 14 109 (100Cr6) steel. The thesis is focused on the optimization of overlaps arising due to pressed burrs on the edges of the semifinished forging. Currently, the final position of these overlaps is very close to the edge of the pre-forged hole of the cam. Undesired chipping of material occurs during machining of the hole to the exact dimension. The final position of the overlaps is optimized by using the numerical simulation in Simufact Forming 15.0, including a verification simulation for optimal parameter settings. Various diameters of semifinished products, turned tools, and modification of shapes of the tools are tested in the thesis to prevent occurrence of the overlaps in undesired positions.

Effective Search for Overlaps in NGS Data
Matocha, Petr ; Martínek, Tomáš (referee) ; Puterová, Janka (advisor)
The main theme of this work is the detection of overlaps in NGS data. The work contains an overview of NGS sequencing technologies that are the source of NGS data. In the thesis, the problem of overlapping detection is generally defined. Next, an overview of the available algorithms and approaches for detecting overlaps in NGS data is created. Principles of these algorithms are described herein. In the second part of this work a suitable tool for detecting approximate overlaps in NGS data is designed and its implementation is described herein. In conclusion, the experiments performed with this tool and the conclusions that follow are summarized and described.
