Dynamic Template Adjustment in Continuous Keystroke Dynamics
Kulich, Martin ; Orság, Filip (referee) ; Drahanský, Martin (advisor)
Dynamika úhozů kláves je jednou z behaviorálních biometrických charakteristik, kterou je možné použít pro průběžnou autentizaci uživatelů. Vzhledem k tomu, že styl psaní na klávesnici se v čase mění, je potřeba rovněž upravovat biometrickou šablonu. Tímto problémem se dosud, alespoň pokud je autorovi známo, žádná studie nezabývala. Tato diplomová práce se pokouší tuto mezeru zaplnit. S pomocí dat o časování úhozů od 22 dobrovolníků bylo otestováno několik technik klasifikace, zda je možné je upravit na online klasifikátory, zdokonalující se bez učitele. Výrazné zlepšení v rozpoznání útočníka bylo zaznamenáno u jednotřídového statistického klasifikátoru založeného na normované Euklidovské vzdálenosti, v průměru o 23,7 % proti původní verzi bez adaptace, zlepšení však bylo pozorováno u všech testovacích sad. Změna míry rozpoznání správného uživatele se oproti tomu různila, avšak stále zůstávala na přijatelných hodnotách.

HUNALOVÁ, Sára
This bachelor's thesis deals with changes in pedagogical communication between teachers and pupils as a result of the coronavirus pandemic. In 2020, the pandemic caused by the Covid-19 virus affected the entire world, including the Czech Republic. In March 2020, Czech schools succumbed to the nationwide order to close schools and were forced to start distance education, which required a completely different method of communication than face-to-face. The bachelor's thesis is divided into a theoretical and a practical part. The theoretical part explains basic concepts related to interpersonal communication, analyses communication in the pedagogical environment, i.e. between teachers and pupils. It also describes the impact of the coronavirus pandemic on Czech education, the course of distance learning and types of digital technologies that were used at that time. The practical part is focused on a mixed research investigation that will reveal what changes in pedagogical communication between teachers and pupils have occurred as a result of the coronavirus pandemic. The chosen methods of data collection are a questionnaire survey that will be carried out among pupils and a semi-structured interview with selected teachers.

This diploma thesis describes practical activities and related topics during forced distant education due to COVID-19 pandemic. In the theoretical part of thesis, the distant education is defined. I also described some of its features, which includes absence of physical contact, use of communication platforms, synchrony and asynchrony form of lesson, need for some degree of independence and digital competence. Anonymous questionnaires were made to collect the data from students and their science subjects' teachers (biology, chemistry, and physics). The questions were with free answers, closed answers with choices or scale values. Respondents consisted of 543 students and 24 teachers from Prague and Central Bohemian Region. The answers were categorized and frequencies calculated. The values of numeric answers such as mean, median, minimum and maximum were measured. The relationship between data was analysed by Pearson's chi squared test of independence. This study shows that teachers used practical activities such as experiments, observation or creating something less in distance lessons, compared to their face to face lessons. On the contrary tasks based on text work were used more often. The analysis showed that students preferred tasks containing creating something. Most teachers taught in both...
