Distributed Systems Simulation
Ďuriš, Anton ; Šeda, Miloš (oponent) ; Matoušek, Radomil (vedoucí práce)
This thesis is focused on distributed systems modeling using Petri nets. Distributed systems are increasingly being implemented in applications and computing systems, where their task is to ensure sufficient performance and stability for a large number of its users. When modeling a distributed systems, stochastic behavior of Petri nets is important, which will provide more realistic simulations. Therefore, this thesis focuses mainly on timed Petri nets. The theoretical part of this thesis summarizes distributed systems, their properties, types and available architectures, as well as Petri nets, their representation, types and the principle of an operation. In the practical part, two models were implemented, namely a horizontally scaled web application divided into several services with a distributed database and a large grid computing system, more precisely the BOINC platform with the Folding@home project. Both models were implemented using the PetNetSim library of Python. The goal of this thesis is to perform simulations on the created models for different scenarios of their behavior.

Processing of big data from measurements and simulations of dynamic systems
Ďuriš, Anton ; Musil, Filip (oponent) ; Kšica, Filip (vedoucí práce)
This thesis is focused on Big data processing from modern technical devices. Big data processing is a time-consuming and complex process requiring powerful hardware, however, there are some methods which enable Big data processing even on a personal computer. In the theoretical part of this thesis, available methods and functions for Big data processing, which are integrated within software and programming languages, are summarized. We focus on TDMS file format, its features and opening options in software and programming languages and their comparison. Then, data preprocessing methods accelerating processing and analysis are listed. In the practical part of this thesis, a graphical user interface in Matlab environment for TDMS file format processing with implemented data preprocessing methods is created. The aim of this thesis is to make processing with this file format more efficient by using a personal computer.
