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.

Comparison of Classical Planning Methods
Černianska, Rebeka ; Zbořil, František (referee) ; Zbořil, František (advisor)
This bachelor's thesis deals with the topic of automated planning and the methods which deal with its problems. The analysis and comparison of the methods STRIPS, Graphplan and HTN takes place, which implement different approaches to planning. Their performance is tested on typical planning problems, which focus on various planning challenges. The goal was to find suitable planning problems for each of the methods, as well as their strong and weak points regarding the given problem. For testing purposes, existing implementations of the methods were used, which showcase their behaviour.

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.

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.

Development of mobile application for organizing time for iOS and its publishing on the App Store
SCHUH, Tom
The aim of this bachelor work is to create a sheduler application for IOS mobile phones, using the Xamarin development platform and publishing the aplication in the App Store. Users can plan activities, meetings, and other tasks, for all of this task he can set a notification, a category or write a short description of the activity. The theoretical part of the bachelor thesis presents the development platform Xamarin, the tools used for the aplication development and the description of a creation an IOS application by using the Xamarin development platform in Windows operating systems. The practical part describes the development of a mobile applications from the creation of the user interface, the programming of the application logic to a connection with an Apple calendar.

UI Specification aplication for shift records.
Franc, David ; Pavlíček, Josef (advisor) ; Nielsen, Jan (referee)
The purpose of this bachelor thesis is to create a UI Specification of a design for a shift planning application which also keeps records of shifts. The user interface of this application is particularly designed for managers and for their employees.
The first part of this thesis outlines the theory regarding a development of the user interface and the UI Specification. Moreover, this part depicts students experiences of shift planning in various job positions.
The second part of this work describes the process of developing the UI specification, especially, the motivation, goals and personals. Furthermore, various application designs are analysed regarding the use cases and scripts of each solution. Finally, the testing of the most suitable design is depicted and evaluated.
The concluding part of this thesis consists of an evaluation of the whole thesis and the final summary.
