Implementation, validation and experimental evaluation of a self-stabilizing randomized Byzantine-tolerant binary consensus algorithm
(Πανεπιστήμιο Κύπρου, Σχολή Θετικών και Εφαρμοσμένων Επιστημών / University of Cyprus, Faculty of Pure and Applied Sciences, 2022-05-31)
Binary consensus is a problem in which a set of processors must agree on a single binary value. In asynchronous systems, where a subset of the processors may be malicious, this challenge gets more challenging. We study ...
Front-end interface for a distributed storage system using laravel
(Πανεπιστήμιο Κύπρου, Σχολή Θετικών και Εφαρμοσμένων Επιστημών / University of Cyprus, Faculty of Pure and Applied Sciences, 2023-05-31)
This Thesis is about a distributed system application which is able to manage large shared data objects in distributed storage systems (DSS) while increasing the number of concurrent accesses, maintaining high levels of ...
Ontological query rewriting: termination criteria
(Πανεπιστήμιο Κύπρου, Σχολή Θετικών και Εφαρμοσμένων Επιστημών / University of Cyprus, Faculty of Pure and Applied Sciences, 2022-12)
Ontological queries are queries evaluated against a database and an ontology, i.e. a set of logic rules and constraints from which new knowledge can be derived from. Ontological database systems can thus be more powerful ...
Implentation,validation and experimental evaluation of a distributed randomized common coin algorithm
(Πανεπιστήμιο Κύπρου, Σχολή Θετικών και Εφαρμοσμένων Επιστημών / University of Cyprus, Faculty of Pure and Applied Sciences, 2022-07-28)
A crucial problem found in distributed system is to achieve trustworthyness. If we know who to trust then we can try and reach consensus which is to decide a common value for everyone. This becomes significantly more ...
