IRC Logbot
Průša, Vojtěch ; Rychlý, Marek (referee) ; Burget, Radek (advisor)
p { margin-bottom: 0.1in; direction: ltr; color: rgb(0, 0, 0); line-height: 120%; }p.western { font-family: "Times New Roman",serif; font-size: 11pt; }p.cjk { font-family: "Times New Roman",serif; font-size: 11pt; }p.ctl { font-family: "Times New Roman",serif; font-size: 12pt; }a:link { color: rgb(0, 0, 255); } For web application development it is currently possible to use the full range of web technologies. Older technologies have been replaced by new ones and we need to keep up with the current trend in application development for safety, reliability and low resource consumption. The aim of this work is to create a functional IRC logging boot application that supports multichannel recording, rotate records and search them with keywords and design a suitable user interface. The technologies used should be the Scala programming language, the React JavaScript library, the Docker container tool and the OpenShift platform. Describe the use of technologies to make it easy to create other applications on a similar principle using modern web technologies.

Industrial data collection system
Hvizdák, Lukáš ; Jirgl, Miroslav (referee) ; Bradáč, Zdeněk (advisor)
The master thesis focuses on the design and implementation of data collection from production using a PLC into an SQL database located in the cloud and subsequent visualization. The work describes the applicable communication protocols MQTT and OPC UA with the fact that the protocol MQTT was selected. It deals with securing data transfer from the line to the cloud using the TLS protocol. The individual cloud services and their possibilities for data collection are described here. The work deals with the possibilities of data visualization using existing open source solutions and the differences between them. I describe the possibilities of modifying the open source environment of the Grafany project. Real dashboards from production are presented. The data collection system was deployed in two plants for testing.

Application of simulation model of access network
Szymeczek, Andrzej ; Sládok, Ondřej (referee) ; Grenar, David (advisor)
The topic of the diploma thesis is " Application of simulation model of access network". The aim of the thesis was to create a part of the access network in which were tested simulations for TCP and UDP traffic. The theoretical part of the thesis deals with general information about the GNS3 program and the possibilities which this program allows. The next part of the thesis describes the Mikrotik RouterOS program, which was used in the topology. The next section describes the types of routing in IP networks, as well as the types of packet delivery. The practical part deals with the creation of test topologies and verification of the performance of the simulation tool. Furthermore, the practical part deals with the programming of a network generator for TCP and UDP traffic in the network. The generator was created by using a Bash script and a combination of the dd and nc commands. At the end, the thesis describes the results of simulations in terms of transmission speed, network throughput, packet size distribution and in the case of TCP also bidirectional delay – RTT.

Code Generation from Object Oriented Petri Nets
Kelemen, Erik ; Janoušek, Vladimír (referee) ; Kočí, Radek (advisor)
This thesis focuses on transformation model described by object oriented Petri net to sequence diagram, which allows reverse mapping to original description. As a solution is used discrete simulation of model described in PNtalk language. Result of work is fully automated generator, which generates sequence diagram according to gathered data from simulation. Generator aims for minimal loss of relevant information and presenting valid sequence diagram.

Development of Dataster Tool
Vlach, Martin ; Holík, Lukáš (referee) ; Smrčka, Aleš (advisor)
This bachelor thesis deals with expansion of existing web application Dataster in Testos platform. This application serves as a user interface for dbgenx tool from the same platform. The main purpose of Dataster is a user-friendly generation of randomized structured data which are used as a database test content. The first goal of this bachelor thesis was, in particular, to extend dbgenx tool with the possibility of generating test data according to the coverage criteria of combinatorial testing. An existing tool Combine from Testos platform has been selected for this purpose. The other part of the thesis deals with a number of small adjustments and expansion of Dataster web application, for a improvement of usability and overall user-friendliness of this application.

Employee Attendance System
Bartošek, Jan ; Kučera, Jan (referee) ; Kocnová, Jitka (advisor)
This bachelor's thesis concerns to design and implementation of a time and attendancesystem to track the employees in the company. In the first part defines what does a timeand attendance system mean and presents both statistics data and existing systems. In thenext part aims on designing such a software able to track employees, manage vacation andexport records. Continues with a list of used technologies and implementation of the systemitself. At the end the proccess and results of testing the system are described.

Remote Deployment of InfiSpector
Číž, Marek ; Šimková, Hana (referee) ; Lengál, Ondřej (advisor)
InfiSpector je aplikace, která graficky zobrazuje komunikaci mezi uzly Infinispan serverů. Chceme oddělit infrastrukturu InfiSpectoru od aplikace jako takové. Důsledkem oddělení infrastury InfiSpectoru od samotné aplikace je přenesení veškeré starosti a správy InfiSpectoru z uživatele na vzdálenou internetovou službu, kde bude aplikace běžet na vzdáleném serveru. Uživatel se ke vzdálenému serveru již jen připojí, uživateli odpadne nutnost instalovat aplikaci na svém zařízení, a tak se může místo konfigurace InfiSpectoru soustředit na jeho využívání. Vzdálená internetová služba umožňuje jejímu uživateli sdílet výpočetní prostředky, například servery a aplikace. Vzdálená internetová služba umožňuje i využivání externích internetových uložišť pro vzdálené uložení dat. Tím, že je vzdálená internetová služba volně přístupná na internetu, je i dobře přístupná z každého počítače nebo telefonu s přístupem na internet. Pro InfiSpector byla zvolena na základě výzkumu vzdálená internetová služba zvaná Openshift, umožňující spravovat, vyvíjet a provozovat aplikace. Openshift navíc nabízí testovací účet zdarma pro každého vývojáře.\newline V bakalářské práci se nachází i popis, přehled a nastavení souborů nejen pro části InfiSpectoru zajišťující správu a zpracování dat, ale i pro nasazení, vývoj a provoz InfiSpectoru na vzdálené internetové službě Openshift.

Continuous Integration Dashboard
Abramov, Mikhail ; Rychlý, Marek (referee) ; Burget, Radek (advisor)
Tato bakalářská práce se zabývá vývojem webové aplikace pro integraci nástrojů CI/CD. Úkolem bylo prostudovat dostupné technologie a připravit aplikaci odpovídající zadaným požadavkům. Během implementace systému byly nastudovány aspekty vývoje, jako jsou nástroje CI/CD, rámce serveru, uživatelské rámce, databáze, technologie webových serverů, nástroje pro práci s kontejnery. Výsledkem bakalářské práce je aplikace skládající se ze tří částí: serverová část, klientská část a databáze. Tato aplikace je rozdělená do tří částí a připravena ke spuštění v nástrojích kontejnerizace.

Utilization of Linux Containers for HW/SW Co-Design
Juřica, Jiří ; Přikryl, Zdeněk (referee) ; Hruška, Tomáš (advisor)
In this bachelor thesis a way of replacement standard virtual machines by Linux containers is described. The goal is to create a~fully working system for performing parallel jobs with prepared environments for software build and test purposes. For containerization the Docker platform was chosen, which is used with automation tool for computers preparation. The system is also connected with continuous integration tool called Jenkins. This solution proves that usage of the Linux containers is more efficient than older virtualization technologies. The due time of each job was shortened about 24 % in average. The main benefits of this thesis is the comparison of two ways of virtualization and the introduction to the Docker technology.
