State of charge prediction of lead acid batteries
Chochola, Ondřej ; Bača, Petr (referee) ; Křivík, Petr (advisor)
The general aim of the thesis is a detailed examination of battery charging condition possibility of lead-acid accumulator with the help of pulse current method. The methodology consists of experimental cell testing by pulse battery charging and pulse battery discharging during a progressive change of charging and discharging current as well as charging and discharging time change. The testing procedure proceeds at a various battery charging condition. Principal aim of this work is to compare final voltage dependencies and to establish the usability of pulse current method to determine battery charging condition.

Brna, Filip ; Homoliak, Ivan (referee) ; Tamaškovič, Marek (advisor)
This thesis aims to analyze the security and usability of cryptocurrency wallets of different categories. The work is focused on familiarizing with the most used cryptocurrency wallets, threats related to their use, subsequent testing of the selected wallets with the proposed test scenarios, and evaluation of the testing supplemented with the definition of several recommendations for their proper use. In the systematic testing, the method of designing test scenarios was used, followed by systematic testing, and finally, the results were evaluated. The research conducted found that the most widely used cryptocurrency wallets achieve a high level of security against the described threats and offer a wide range of possibilities for their use. The results of this work allow users to understand the issues associated with storing and handling cryptocurrencies more efficiently. Based on the results of the testing, the user has the possibility to choose a cryptocurrency wallet precisely according to his user's needs and security requirements.

Relevance of Usable Security Guidelines from IT Professional Point of View
Galanská, Katarína ; Polčák, Libor (referee) ; Malinka, Kamil (advisor)
Vyvážení bezpečnosti a použitelnosti bylo vždy výzvou. Navzdory důležitosti zabezpečení softwaru jsou bezpečnostní pokyny a standardy často příliš komplikované, náchylné k chybám nebo časově náročné. Tato nerovnováha iniciovala vznik pojmu použitelné bezpečnosti. Po celá léta to byl běžný výzkumný problém. Zatímco softvér by měl být vyvíjen s ohledem na použitelnost koncových uživatelů, bezpečnostním standardům a směrnicím, které používají IT profesionálové, není z hlediska použitelnosti často věnována dostatečná pozornost. Vzhledem k tomu, že se od odborníků v oblasti IT očekává vyšší úroveň znalostí, často čelí velmi složitým oblastem, když se snaží vyhovět konkrétním bezpečnostním standardům nebo dodržovat konkrétní pokyny. Tato práce představuje studium současného povědomí v oblasti použitelné bezpečnosti. Práce sestává z provedeného průzkumu, analýzy stávajících použitelných bezpečnostních pokynů a navrhuje vzdělávací pomůcku k řešení problémů, které výzkum přinesl. Hodnocení vzdělávací pomůcky ukázalo pozitivní dopad na povědomí IT odborníků.
