Selecting Objects in Augmented Reality
Pribylina, Martin ; Materna, Zdeněk (referee) ; Kapinus, Michal (advisor)
This work proposes and tests methods for object selection in augmented reality. The work focuses on selecting objects that overlap with each other in densely populated clusters. The proposed selection methods are direct selection, cursor, and list. As part of the work, an application has been developed that allows testing of the three methods and measures accuracy, time, motion and other criteria for a thorough evaluation of their applicability. The application was implemented using Unity and ARCore. A user study with 16 respondents was conducted using the test application. The results of the work show the advantages and disadvantages of each selection.

Kubernetes support for Quarkus QE Test Framework
Troitskii, Georgii ; Smrčka, Aleš (referee) ; Rogalewicz, Adam (advisor)
This thesis focuses on improving the open-source Quarkus QE Test Framework project, designated for testing applications built on the Quarkus framework. The goal is to add support for automated test execution on the Kubernetes platform. To achieve this goal, a Kubernetes cluster was installed in a virtual machine on the OpenStack platform. Integration between Jenkins and GitHub CI in the Quarkus QE Test Framework was set up using GitHub Pull Request Builder plugin for Jenkins. This integration allows Kubernetes to automatically run tests when creating Pull Requests on GitHub after entering a specific trigger phrase in the Pull Request. This solution enables fully automated test execution in Kubernetes as part of the GitHub CI pipeline, expanding the list of external platforms on which Quarkus QE team tests Quarkus applications.

Analysis of Clustering Methods
Lipták, Šimon ; Bartík, Vladimír (referee) ; Burgetová, Ivana (advisor)
The aim of this master's thesis was to get acquainted with cluster analysis, clustering methods and their theoretical properties. It was necessary select clustering algorithms whose properties will be analyzed, find and select data sets on which these algorithms will be triggered. Also, the goal was to design and implement an application that will evaluate and display clustering results in an appropriate manner. The last step was to analyze the results and compare them with theoretical assumptions.

Optimization of Run Configurations of k-Wave Jobs
Sasák, Tomáš ; Jaroš, Marta (referee) ; Jaroš, Jiří (advisor)
This thesis focuses on scheduling, i.e. correct approximation of configurations used to run k-Wave simulations on supercomputers from the IT4Innovations infrastructure. Especially, for clusters Salomon and Anselm. A single work is composed of a set which contains many simulations. Every simulation is executed by some code from the k-Wave toolbox. To calculate the simulation, it is necesarry to select a suitable configuration, which means the amount of supercomputer resources (number of nodes, i.e. cores), and the duration of the rental. Creation of an ideal configuration is complicated and is even harder for an inexperienced user. The approximation is made based on the empiric data, obtained from multiple executions of different sets of simulations on given clusters. This data is stored and used by a set of approximators, which performs the actual approximation by methods of interpolation and regression. The text describes the implementation of the final scheduler. By experimenting, the most efficient methods for this problem has found out to be Akima spline, PCHIP interpolation and cubic spline. The main contribution of this work is creation of a tool which can find suitable configuration for k-Wave simulation without knowing the code or having lots of experience with its usage.

Virtualization and optimization of IT infrastructure in the company
Lipták, Roman ; Hladiš, Peter (referee) ; Ondrák, Viktor (advisor)
Master’s thesis deals with the use of virtualization and consolidation technologies in order to optimize IT infrastructure in a selected company. The analysis contains current state of IT infrastructure and requirements for future upgrade. The theoretical part contains description of technologies and procedures used in virtualization and consolidation. Subsequently, the proposal of optimization and expansion of IT equipment is created together with management, implementation and economic evaluation of the solution.

A Mini-Cluster Based on Microcontroller Computing Nodes
Šídlo, Boleslav ; Mrázek, Vojtěch (referee) ; Bidlo, Michal (advisor)
The objective of this bachelor thesis is to investigate a low-cost computing cluster, composed of microcontrollers-based nodes, for parallel computing tasks. The work deals with the behaviour and limitations of the platform in various situations. Experiments were performed using 4 development boards equipped with 8-bit microcontrollers. I2C seriál interface was used for the communication between the nodes. The experiments were devoted to the comparison of computing times of a sequential algorithm (running on a single minrocontroller only) and the parallel version using the cluster. The results showed that the cluster can speed-up the computation of applications that does not require a high communication overhead. Moreover, the microcontrollers applied showed as unsuitable for floating-point computing if a high accuracy of the results is required.

Testing Environment via Cluster Solution
Hostačný, Peter ; Kočí, Radek (referee) ; Smrčka, Aleš (advisor)
Testos is a project that aims to create a set of tools supporting automated software testing. One of its components is computational cluster whose main goal is to execute parallel tasks and provide computational resources to other tools in the project. This work details the process of its design, implementation and integration with the Testos project. It is expected that the resulting system will be in use after Testos bus is completed.

Linux OS Monitoring
Korček, Juraj ; Očenášek, Pavel (referee) ; Trchalík, Roman (advisor)
The aim of this bachelor's thesis is design and implementation of monitoring tool for GNU/Linux operating systems. This program monitors logs created by system, system load and computer resources. It notifies system administrator in case of high system load, abnormal behavior or when an error occurs. The resulting product is especially aimed for system administrators of GNU/Linux, whose work will be simplified due to this software utility, which sends notification of only important system changes. It is implemented in scripting language Python and divided into smaller independent scripts for easy implementation of new scripts in the future. This programming language was chosen to ensure operation among all GNU/Linux distributions.
