Intelligent Agents in Wireless Networks
Kružliak, Miroslav ; Samek, Jan (referee) ; Zbořil, František (advisor)
This Master thesis deals with synchronization of sensor nodes in wireless sensor net. It is used event ordering by the implementation of logical clocks . Lamport's algorithm is used here for synchronization, which is trying to order events within the given system. The thesis also evaluates how appropriate this principle for synchronization is. The implementation has been carried out in agent-oriented language AgentSpeak on the Jason platform. Samson environment has been used and modified for observation of this synchronization's behaviour and testing purposes.

OFDM demodulator implementation in FPGA
Solar, Pavel ; Urban, Josef (referee) ; Maršálek, Roman (advisor)
The master's thesis briefly analyses the principle of OFDM modulation, possibilities of the synchronization and channel estimation in OFDM. The simply model of OFDM system is made in MATLAB. Because of the implementation in FPGA is generated the behavioral description of the OFDM demodulator through the combination of the schematics description and the description in the VHDL language. The ISE development environment is used.

Stability and chaos in nonlinear dynamical systems
Khůlová, Jitka ; Tomášek, Petr (referee) ; Čermák, Jan (advisor)
Diplomová práce pojednává o teorii chaotických dynamických systémů, speciálně se pak zabývá Rösslerovým systémem. Kromě standardních výpočtů spojených s bifurkační analýzou se práce zaměřuje na problém stabilizace, konkrétně na stabilizaci rovnovážných bodů. Ke stabilizaci je využita základní metoda zpětnovazebního řízení s časovým zpožděním. Významnou část práce tvoří zavedení a implementace obecné metody pro hledání vhodné volby parametrů vedoucí k úspěšné stabiliaci. Dalším diskutovaným tématem je možnost synchronizace dvou Rösslerových systémů pomocí různých synchronizačních schémat.

Web application HelpDesk and data synchronization
Balogh, Pavel ; Heriban, Pavel (referee) ; Šťastný, Jiří (advisor)
The thesis deals with the development of the web-based Helpdesk application which ensures and supports the communication with Internet users. The first section of the thesis contains a brief description of the individual means and tools used by the developer. The practical part describes the design and development of the individual layers of the web-based application concerned. The latter section also mentions the development and usage of the required synchronization and code generation tools.

Management of terminal nodes of data networks
Knol, Radek ; Nagy, Ľuboš (referee) ; Novotný, Vít (advisor)
The aim of this Bachelor Thesis is to analyze different possibilities of administration of external nodes of data networks. On the basis of this thesis an application for the operating system Microsoft Windows has been created which is intended to enable and facilitate the administration and configuration of individual network components, such as computers, servers, network switches, hubs, IP phones, IP cameras and other devices. This application can work with groups of devices, it can sort them according to set point criteria, and it can apply different functions to the individual components or to the whole target group. This application provides all essential operations for the administration of the network and of the individual components in a well-arranged interface, including synchronization rules for data updates on personal computers. The availability of different functions and access to the individual groups of devices can be defined by means of user rights. Another part of this thesis is a proposal of a system for automatic updates of the operating systems MS Windows and other programs of the company Microsoft.

Transmission of Digital Information over Audio
Bujnovský, Michael ; Malenovský, Vladimír (referee) ; Černocký, Jan (advisor)
Cílem této práce je umožnit přenést binární informace mezi dvěma zařízeními jen za pomocí zvuku. Práce začíná analýzou existujících řešení. Dále popisuje různé techniky digitální modulace, věnuje se synchronizaci a vlastnímu protokolu zapouzdřující data. Velkou částí práce jsou testy úspěšnosti přenosu za užití různých nastavení frekvencí a prostředí. Na základě výsledků testů je implementovaná uživatelská aplikace, umožňující demonstraci systému.

Framework for Data Synchronization in the Context of Apple User Applications
Klembara, Filip ; Smrčka, Aleš (referee) ; Hrubý, Martin (advisor)
The goal of this thesis is to design and implement a library for data synchronization between multiple client's devices in the context of the ecosystem of a single application targeting the iOS, iPadOS or MacOS operating system. The work focuses on the simple integration of the library into existing applications using the Realm database system and on the simple way to connect the user interface with the synchronization process. I solved the chosen problem by designing a synchronization protocol primarily based on log synchronization to distribute changes between the client and the server, implementing a library to monitor changes in the client's database and distribute them to the server, and implementing a server library to integrate received changes and distribute them with help of notifications. The solution provides an easy way to implement data synchronization between multiple devices using custom database server and with the ability to define how to handle new changes of objects presented in the user interface during the synchronization. Created library can be quickly and easily integrated and thus effectively speed up the application development process.

Tool for Business Processes Support on Mobile Platforms
Svoboda, Roman ; Trchalík, Roman (referee) ; Kreslíková, Jitka (advisor)
The scope of this thesis is to design tools to support business processes on mobile platforms. The work deals with both the Enterprise Resource Planning systems issue, as well as the database synchronization and the possibilities of secure data transmission between the mobile device and the server. The work also includes familiarization with the most widely used mobile platforms and tools for multi-platform application development. The last part of the thesis comprises a model of an application meant to support business processes on mobile devices, including a description of its implementation, used tools and testing.

Fast Synchronization of New Nodes in the Fantom Opera Platform
Mlejnek, Matěj ; Homoliak, Ivan (referee) ; Perešíni, Martin (advisor)
Cílem této diplomové práce je prozkoumat aktuální způsoby rychlé synchronizace nových uzlů v rámci jednotlivých blockchain sítí dle závislostí na jednotlivých konsenzech, porovnat jednotlivá řešení mezi sebou, navrhnout možné řešení a naimplementovat novou rychlou synchronizaci pro blockchainovou síť Fantom Opera. Řešení spočívá v tom, že nově připojený uzel se místo do P2P sítě přímo připojí k existujícímu nodu a stáhne si od něj potřebná data pro co nejrychlejší synchronizování se zbytkem sítě.
