Library and Tools for Server-Side DNSSEC Implementation
Včelák, Jan ; Grégr, Matěj (referee) ; Matoušek, Petr (advisor)
Tato práce se zabývá analýzou současných open source řešení pro zabezpečení DNS zón pomocí technologie DNSSEC. Na základě provedené rešerše je navržena a implementována nová knihovna pro použití na autoritativních DNS serverech. Cílem knihovny je zachovat výhody stávajících řešení a vyřešit jejich nedostatky. Součástí návrhu je i sada nástrojů pro správu politiky a klíčů. Funkčnost vytvořené knihovny je ukázána na jejím použití v serveru Knot DNS.

Support of Snapshot and Rollback of Configuration Files in Fedora
Včelák, Jan ; Rogalewicz, Adam (referee) ; Smrčka, Aleš (advisor)
This thesis deals with current possibilities of creating backups and versioning of configuration files in GNU/Linux operating system. Based on the findings a new tool for Fedora distribution was designed, implemented, and tested. The aim of the tool is to keep the benefits of existing solutions and to eliminate their drawbacks. In addition, it brings some new and useful features like synchronization with remote server and integration with other management tools.

Diagnostics of subclinical atherosclerosis
Včelák, Jan ; Kraml, Pavel (advisor)
Atherosclerosis and its occurrence has become a highly actual problem of the industrial world. Statistics clearly show that 50% of deaths in the Czech Republic is caused by cardiovascular diseases associated with atherosclerosis. The sooner we are able to diagnose it's early stages, the sooner adequate therapy can be initiated in order to slower the progression of already existing atherosclerotic lesions. The methods that help to diagnose asymptomatic atherosclerosis contain especially the carotid ultrasound, the coronary calcium score and ankle-brachial-index. Carotid or aortic calcifications can be also randomly found on general chest X-ray, however. Advantage of these methods is their non-invasiveness and the instant availability of results. Additionally, the costs are relatively low (with exception of CCS). All methods require adequate equipment and knowledge.
