I/O Subsystem Optimalization Using SSD
Bělousov, Petr ; Chalupníček, Kamil (referee) ; Kašpárek, Tomáš (advisor)
The bachelor thesis examines IO subsystem optimization using SSD cache to speed up HDDs. I examined possible server loads and identified those that are suitable for caching. In the first part I introduce 2 caching solutions, LVM cache and B-cache with their management capabilities and 2 filesystems Ext4 and XFS. In the second part IO performance of LVM cache and B-cache with Ext4 and XFS filesystem is benchmarked and compared to an uncached HDD array.

JamVM: An Alternative Java Virtual Machine
Kalman, Ondřej ; Kočí, Radek (referee) ; Dudka, Vendula (advisor)
This thesis deals with comparison of two virtual machines, namely HotSpot and JamVM. The first chapters of this thesis contain introduction to Java platform and summarize general properties and principals of Java virtual machine. The next chapters follow on this introduction and compare different properties of HotSpot and JamVM virtual machines. Based on these differences was designed and described set of benchmark tests which was also implemented and performed as practical part of this thesis. Last chapters deals with results of performed benchmark tests.

Integration of JMS Providers to Third Parties
Žiaková, Nikoleta ; Letko, Zdeněk (referee) ; Dudka, Vendula (advisor)
This thesis deals with messaging and integration of third-party JMS providers into JBoss application server. The aim of the thesis was to design and implement a general-purpose testsuite to verify the proposed integration. First requirement was to get familiar with key technologies for integration including Java Message Service, Java EE Connector Architecture, selected JMS providers and JBoss AS. Specific procedures of integration were designed and described for JMS providers Apache ActiveMQ, IBM WebSphere MQ and Red Hat MRG Messaging. The testsuite implemented to verify the functionlity of the integration focuses on four areas - transactions, clustering, high availibility and performance. The process of testing was automated using continuous integration tool Jenkins. Finally the test application was used to evaluate functionality of the integration and compare different JMS providers and various versions of JBoss AS.

Evaluation of selected parameters in American football players as possible causes of their injuries
Chramosta, Roman ; Kaplan, Aleš (advisor) ; Jantoš, Stanislav (referee)
Title: Evaluation of selected parameters in American football players as possible causes of their injuries Objectives: The aim of this thesis is, after studying selected theoretical backgrounds, to point out at the performance players of American football deliberately selected team to the possible causes of injuries (with special focus on the area knee joint) by evaluating body parameters, then selected three tests and at the same time by evaluating the screening of two positions in progress vertical jump. Methods: To write down the diploma thesis, we mainly used knowledge and conclusions from a literature search of foreign articles and studies dealing with the issue of injuries, injury prevention, sports performance, and normative data. In the next step, testing of selected three tests and subsequent normative evaluation was performed. Screening was also important for the evaluation of two positions during the vertical jump. Results: Through hand-picked performance tests, it was found that the selected players from the team achieved a sufficient level of movement based on the results according to standardized tables that we used. In comparison with professional players and the norm set out by Palmieri (2019), the players that we tested lag behind. As for the injuries in the selected group, the...
