System for Support of Short-Term Car Rentals Based on Carsharing
Vrtal, Petr ; Bidlo, Michal (referee) ; Šimek, Václav (advisor)
The aim of this thesis is to create a system for the transformation of an ordinary passenger car into a vehicle capable of sharing in the form of short-term loans. Vehicle rentals are completely unattended, which was achieved by implementing service applications in the form of an administration and user tool. The administrative application was created using web technologies, primarily Next.js and React. The customer application was implemented with the goal of high portability, and therefore its development was directed to mobile platforms using the React Native framework and the Expo tool. The vehicle is equipped with its own designed IoT end device in the form of a printed circuit board, capable of permanent wireless connection to the network based on LTE-M technology and MQTT protocol. The purpose of this device is to provide current vehicle data obtained by reading communication on the CAN bus, connecting to a standard OBD-II diagnostic port. An important part of the work was the execution of a series of tests of all sub-aspects of the implemented architecture, focusing mainly on reliability, resulting functionality and user-friendliness. The resulting system was tested in real operation and represents a way of non-invasively transforming a regular passenger car into a car capable of sharing.

Interactive Navigation through an User Database in Sqlite3
Vrtal, Petr ; Kočí, Radek (referee) ; Hrubý, Martin (advisor)
The aim of this thesis is to create a web application enhancing developer productivity, capable of interactive and intuitive browsing of a SQLite file database with a specified schema, representing user data. The enhancement is achieved specificaly by using a series of common views of this database and mechanisms for transition between these views. The web application is build using the Laravel PHP framework. User interface functionality is build mainly using Livewire framework by creating its interconnected components. An important part of the work was to determine by seeries of tests the level of resistence of the application against invalid user input as well as the speed analysis of the user's work with the application. The resulting web application allows a very specific group of users a clear orientation in the data of a specific production task, which is uploaded to the server by the users themselfs and the application offers them the option to view this data.
