Test Planning Tool Extension for Distributed Systems
Mészáros, Filip ; Ráb, Jaroslav (referee) ; Ščuglík, František (advisor)
This bachelor thesis is about automatical software testing using the testing scheduler. It describes creation of the extension for the existing testing scheduler, so it will be possible to split effectively a group of tests to segments, that will be executed independently on each other. Tests are splitted according to the common characteristics of the enviroment, that need to be prepared for each test, and according to the dependencies between the tests. Furthermore, it describes what optimizations are used for splitting of the tests to subsets. Each subset of the tests runs on a standalone testing system, so the time needed for succesful completion of testing with the given set of tests is reduced. Created tool is succesfully used during everyday testing of the several products in the Acision company, to which was this tool made.

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.

Design and Implementation of Real-Time Operating System Kernels Running on HC08
Bednář, Jan ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
The project is aimed at testing the kernels of real-time OS within the HC08 platform. The RM, EDF and polled loop mechanisms are being compared as well as freely available FreeRSTOS and QP systems. The project also incorporates descriptions of techniques used in the development, obtaining and the implementation of test environments. The evaluation is based on the tests made within the HC08 platform and the knowledge gained from the programming for every individual type of real-time OS.

Implementation of Personal Scheduler
Filák, Jakub ; Květoňová, Šárka (referee) ; Lukáš, Roman (advisor)
The goal of this bachelor´s thesis is to explore the possibilities of the time scheduling and to create a tool for its simplification. Besides managing personal tasks and events, the tool can also be used for planning appointments with other users, mainly due to a user diaries sharing and a searching tool for appropriate dates. The first part of the thesis deals with the technologies employed, followed with a part concerning the requirements for the time scheduling tool and a description of an implementation of the tool. In the last part the programme capabilities are evaluated, along with the results of the work.

QoS simulation model in NS2
Balej, Jiří ; Burda, Karel (referee) ; Šimek, Milan (advisor)
In this bachelor thesis is described fundamental principle of IPTV and all the necessary conditions for high-quality video and audio signal. In reference is the recommendation of DSL Forum TR-126, where are summarized QoS parameters for IPTV. There is the explanation of Triple play service as a combined distribution of television, telephone and high-speed Internet. In one chapter are presented methods for asssure Quality of Service (QoS). There are described the method of Integrated services and especially Differentiated services. It explains a function of edge and core routers in Differentiated services. Methods for random early detection (RED) a scheduling are described too. The aim of this thesis was to create two laboratory tasks in the Network Simulator 2. The first lab simulates VoIP traffic in data network and assure QoS for VoIP. In the second lab is a simulated the network with Triple play service and the goal is to assure the recommended parameters for IPTV. To resolve the aim of this work, was needed to study the function of Network Simulator 2 and focus on settings for Differentiated services.

Real-Time Operating System with Fixed Task Priority for Raspberry Pi
Kolář, Josef ; Peringer, Petr (referee) ; Janoušek, Vladimír (advisor)
The main goal of this work is to create a support for an open-source real-time operating system on the computer Raspberry Pi 3B+. The project FreeRTOS is selected as a great candidate for further work. The runtime environment and support for user-space applications are presented. Two demonstration applications serve as proofs of support, the first one uses two periodic tasks and reports their state to the serial interface. The second demonstration application runds the same periodic tasks, but reporting the state is done using the CAN bus, for which is the driver realised. The result of this thesis is a working system FreeRTOS for Raspberry Pi 3B+ computer with support for time-critical usages.

Web Application for Collaborative Schedule Management
Novák, David ; Polčák, Libor (referee) ; Dolejška, Daniel (advisor)
This thesis addresses the development of a web application for collaborative schedule management for universities and other institutions. The application aims to implement a schedule editor that allows users to collaborate in real-time using the WebSocket protocol and automatically evaluates conflicts between lessons. Before creating the application itself, existing solutions in the field of collaborative and scheduling editors were studied. The solution of the company IS4U, with whom this thesis is being realized, was studied in the most detail. A design for its improvement was created using an ER diagram and wireframes. The implementation predominantly utilizes TypeScript. On the server side, Node.js runtime environment and the Express.js framework are utilized. The client is implemented using the Vue.js framework. The thesis also includes user testing of the application and considerations for future improvements.
