The examination of the effect of titanium dioxide on the properties of lead-acid batteries
Mlýnek, Martin ; Vaněk, Jiří (referee) ; Bača, Petr (advisor)
Despite, considerable advances in technologies for storing electrical energy, lead-acid batteries are still the most widely used these days even it was invented more than a century ago. The functionality remains the same since its invention. Today´s time puts certain pressure on improving some aspects of the functionality like, heat management, charging and discharging speed, capacity and durability etc..... This bachelor´s thesis is based on the last mentioned, Durability,. The work presents the theory of acid batteries with the history of chemical reaction, technological production processes and battery construction. It is followed by a chapter about titanium and titanium dioxide as an addition of negative active mass where all the aspects are being examined in this work.

Analysis of User Settings on Online Social Networks
Mlýnek, Martin ; Malinka, Kamil (referee) ; Januš, Filip (advisor)
The bachelor thesis deals with the development of a web user interface. The goal was to design and implement an interface for the server part of the Privchecker security tool, which deals with the security of users on social networks. The problem was solved by creating a client web application based on the React JavaScript library. It also addresses the issue of transfering user's credentials, testing of the implemented interface and analysis of user settings.

Analysis of Defects on PCB Using X-RAY
Mlýnek, Martin ; Vala, Radek (referee) ; Řihák, Pavel (advisor)
This thesis is focused on BGA packages and fault detection after rework using X – Ray. There is a description of BGA packages by carrier substrate, techniques of connecting on chip, from mounting packages to repair printed circuit boards (hereafter PCB). Thesis summarizes description of defects, which are created after rework process. There is also description of X – Ray as method for analyzing defects. X – PLANE method used to detect internal structure of BGA packages and it was confirmed by microsection and by software for reconstruction. Description of automatic and manual measurement is follow.
