Centralized Cryptocurrency Exchange with Trusted Computing
Sasák, Tomáš ; Očenášek, Pavel (referee) ; Homoliak, Ivan (advisor)
Táto práca sa zaoberá návrhom, implementáciou a analýzou centralizovanej zmenárne kryptomien, ktorá pracuje na platforme trusted computing. Aktuálne centralizované zmenárne fungujú na základe plnej dôvery používateľa v operátorov zmenárne. Na opačnej strane, decentralizované zmenárne využívajú jeden blockchain a tým sú limitované iba na mince na danom blockchaine. Použitím trusted computing platformy Intel SGX je možné kód zverejniť (open source) a zákazník si dokáže overiť pomocou SGX atestácie (remote attestation) že tento kód beží na platforme zmenárne. Kombináciou so smart contract platformou na verejnom blockchaine zmenáreň dosahuje odolnosť voči nejednoznačnosti a vytvára lepšiu vrstvu bezpečnosti a transparentnosti pre používateľa. Zmenáreň bola implementovaná ako proof-of-concept pomocou programovacieho jazyka Go, za použitím frameworku EGo pre tvorbu SGX enkláv. Pre ukladanie dát bola použitá databáza PebbleDB a relačná databáza PostgreSQL. Smart contract zmenárne bol implementovaný v jazyku Solidity a nasadený na Ethereum. Implementácia je schopná vyhodnotiť približne 35 vkladov mincí za sekundu a 23 ponúk na výmenu mincí za sekundu. Aktualizácia poslednej verzie ledgeru na kontrakte stojí približne 0.00255 ETH, pri tendencií aktualizácie každú minútu deň behu zmenárne stojí približne 3.6742 ETH.

Comparison of Hans Kung and his work Global Ethics with the Civil Religion
Knotek, Daniel ; Hošek, Pavel (advisor) ; Hajko, Dalimír (referee)
This Diploma Thesis deals with two universalistic conceptions, represented by the Swiss Catholic Theologist Hans Küng and his work Global Ethics, and the Civil Religion. In the first part of my text, I bring in the personality of Hans Küng, his work, ideas and the book Global Ethics which received great acclaim on international forum, Churches and society. Küng draws up three basic theses: No world peace without peace among religions. No peace among religions without dialogue between the religions. No dialogue between the religions without accurate knowledge of one another. These theses express the need for a dialogue, being able to formulate viable visions of the future. In the second part of my work, I introduce a less known notion of the Civil Religion with its transformations and development throughout the history. It is a concept exceeding the border of sociology, political science, philosophy and theology, examining the formative processes of the society and its religious reference speech. It penetrates the academic discourse especially in the period between the 1960s and 1980s, as represented e.g. by the American sociologist Robert Bellah. In the third part of my text, I compare both the universalistic conceptions and try to find out where they intersect and in which respect each of them has...

TITLE: Assumptions of consensual communication between pupil in puberty and his teacher ABSTRACT: Communication between the pupil in the period of adolescence and his teacher is mainly influenced by pupil's fase of development and specific features of school environment. The assumption of consensual communication is to know these types of influence and to choose our modes of behaviour accordingly. Interviews with adolescent pupil's proofed the theory mainly that the pupil's need rules and boundaries which the adults should observe consistently and they should let step by step the adolescents make the decisions and allow them to be independent.

Consensus and commercial terms: theoretical and comparative analysis
Kočer, Jan ; Čech, Petr (advisor) ; Pelikán, Robert (referee)
Consensus and commercial terms: theoretical and comparative analysis This final thesis deals with the topic of the battle of the forms using the theoretical apparatus of rules governing the formation of contract. The problem is modeled (and therefore limited) for the case of formation of contract for the sale of goods concluded between merchants when each of them uses his/her own commercial (standard) terms. Another limitation of the thesis is connected with the use of classical contractual paradigm which is based on the continuity of offer and acceptance in the process of contracting. The key element of contract is found in consensus, therefore it is consensus which is analyzed in connection with extensiveness of terms, about which the minds have to meet in order to form the contract, and also in connection with the content of already formed contract. The final thesis has two objectives. First, it is to verify on theoretical level that no matter what principle in the process of formation of contract is used (whether mirror-image rule or not) both law professionals and legal theory are forced to find solutions which are in accordance with the principle of economic analysis of contract. Second, it is to analyze solutions on the formation and content of contract which were adopted by Czech...
