The library for working with sensors allowing distributed processing in FORTH language
Kudela, Kryštof ; Valach, Soběslav (referee) ; Jirgl, Miroslav (advisor)
This bachelor's thesis focuses on the Forth programming language, Forth distributions, smart sensors, distributed systems, and distributed computing. The aim of this thesis is to provide an introduction to the Forth development platform, starting with the basics of Forth programming. It also includes an overview of the eForth, FlashForth, and AmForth operating systems. The theoretical foundations of distributed systems and computations are presented, accompanied by an example of a distributed task. As part of this thesis, a network in the Forth language is created, enabling the implementation of distributed computations using smart sensors.

Metadata Analysis of Cracking Password Task
Pokorný, Šimon ; Hranický, Radek (referee) ; Veselý, Vladimír (advisor)
This thesis deals with the design and implementation of the analytical web dashboard for remote administration of the Fitcrack system. This system is used for distributed password recovery. Web administration is a single-page application which is divided into a server and client part. These parts communicate with each other. There is a lot of information across the system that logged into a database for later analysis or displayed in real-time for the user. The best form to show data is a graphical element of various types (arrow, graph, table, square) and different colors showing what is happening.

Distributed Computing by force of Action Script
Minář, Petr ; Kuba,, Martin (referee) ; Matoušek, Radomil (advisor)
This Master thesis deals with designing and realization of optimalization software in ActionScript 3.0 background. The designed applications realized in terms of computation by standalone and distributed variant and by means of chosen heuristic method called HC12. For verification of a function and performance was select set of testing examples. The main purpose of the work was create public clients in the network internet and calculated partial computing by it. The completed clients are selected by competence and carry on tasks. This research has been supported by the Czech Ministry of Education in the frame of MSM 0021630529 Research Intention Intelligent Systems in Automation.

Optimization of Task Distribution in Fitcrack System
Ženčák, Tomáš ; Ryšavý, Ondřej (referee) ; Hranický, Radek (advisor)
The goal of this thesis is the optimization of task distribution in the Fitcrack system. The improvement is reached by way of increasing the accuracy of the estimation of the computational power of worker nodes, and the prevention of the creation of extremely small tasks, as well as increasing the efficiency of the transfer of the tasks to the worker nodes. In this thesis, the current state of the Fitcrack system is described, tested, and evaluated. This thesis then describes the weak points of the current implementation, proposes ways of remediating them and describes, tests and evaluates the implementation of those proposals.

Raspberry Pi 4 Cluster Management in Nix
Živčák, Adam ; Burget, Radek (referee) ; Rychlý, Marek (advisor)
The scope of this thesis is to design and implement a system for deploying, managing and monitoring a Raspberry Pi cluster using Nix technologies. The thesis describes the benefits of the functional approach of Nix and the subsystems that are based on it. The thesis also results in a supporting web application, providing an intuitive environment for working with cluster configuration deployments and clearly displaying information about the utilization of individual nodes using dashboards. The final part of the thesis is devoted to testing cluster performance using sample distributed computing jobs.

Strategies for Distributed Password Cracking
Večeřa, Vojtěch ; Pluskal, Jan (referee) ; Veselý, Vladimír (advisor)
This thesis introduces viable password recovery tools and their categories as well as the technologies and hardware commonly used in this field of informatics. It follows by an overview of the available benchmarking tools for the given hardware. Thesis later contains a description of the custom benchmarking process targeting the aspects of interest. Later, the thesis moves to a distributed system FITcrack as it proposes and experimentally implements new features. The thesis finishes by comparison of the additions against the original state and highlights the areas of improvement.

Reimplementation of GIS GRASS
Bartoň, Radek ; Peringer, Petr (referee) ; Hrubý, Martin (advisor)
The geographical information system GRASS has become a standard on the field of geographical phenomenon modeling during its 26 years old lifetime. However, its internal structure follows practices from the date of its creation. This thesis aims to design a possible shape of internal parts modernization using a component architecture and object-oriented design patterns with distributed computing and dynamic languages support in mind. The designed system should stay identical from the user's point-of-view. Design results are proven on a prototype library implementation called the GAL Framework.

Web-Based Collaborative Real-Time Editor
Konečný, Martin ; Jaša, Petr (referee) ; Rychlý, Marek (advisor)
Real-time collaboration editing is research area that has been studied for over 20 years. It involves multiple users editing a document such as plain-text, rich-text or an image concurrently over a high-latency network. Many problems involving consistency between users are associated with concurrent document editing, and an innovative technique called Operational Transformation developed by the GROVE (GRoup Outline Viewing Editor) system in 1989 addresses some of these issues. This paper will compare and contrast current implementations of real-time collaborative editors, and on the basis of this analysis describe the creation of a new web-based editor with support for concurrent editing. The design of our web editor will focus on methods of mutual communication between the individual instances of the editors, propagation of text changes, how to solve conflicts between multiple operations, and communication failures.
