Implementation of matrix decomposition and pseudoinversion on FPGA
Röszler, Pavel ; Rajmic, Pavel (referee) ; Smékal, David (advisor)
The purpose of this thesis is to implement algorithms of matrix eigendecomposition and pseudoinverse computation on a Field Programmable Gate Array (FPGA) platform. Firstly, there are described matrix decomposition methods that are broadly used in mentioned algorithms. Next section is focused on the basic theory and methods of computation eigenvalues and eigenvectors as well as matrix pseudoinverse. Several examples of implementation using Matlab are attached. The Vivado High-Level Synthesis tools and libraries were used for final implementation. After the brief introduction into the FPGA fundamentals the thesis continues with a description of implemented blocks. The results of each variant were compared in terms of timing and FPGA utilization. The selected block has been validated on the development board and its arithmetic precision was analyzed.

Mobile Application for Scheduling Activities at Summer Camps
Holub, Ondřej ; Martiček, Štefan (referee) ; Češka, Milan (advisor)
The main goal of this thesis is to design and implement a mobile application assisting in scheduling activities at summer camps taking into account the preferences of camp participants. This is done in a way that ensures the minimization of conflicts with respect to user-defined constraints. QR code scanning is used as an effective method of data input. The main process of finding an optimal solution is formalized as a graph colouring problem and is implemented using the branch and bound method. The created system does not require any other device for its functioning, all the necessary calculations are being executed on a mobile phone of the user. This system has significantly accelerated and simplified the process of scheduling activities at summer camps.

Automatic Attendance of Students at BUT
Urbánek, Frederik ; Hynek, Jiří (referee) ; Tesařová, Alena (advisor)
The time-consuming issue of manually entering attendance is often overlooked, but very important. Student attendance records must be entered manually, either in the application or on paper, which represents a direct proportion of difficulty to the number of students present in the lesson. This problem can be solved using modern technologies that can be implemented in a mobile application. After extensive research, Bluetooth Low Energy and QR codes were found to be the most suitable technologies for this implementation. Thanks to the exchange of information with nearby devices using these technologies, we are able to secure the records of the students present with a mobile device. Part of this bachelor's thesis is also a functional prototype of automated attendance implemented in the My BUT mobile application.

authentication for information system
Jenčík, Štěpán ; Havránek, Martin (advisor) ; Ladislav, Ladislav (referee)
This thesis is focused on authentication methods, for regular private users and company solutions. Based on the analysis of individual authentication methods discussed in a theoretical part, the most suitable solutions are chosen. The practical part then offers various solutions divided into categories based on the users profiles. This presented overview suggests possible follow up discussion topics and an outline of the future development in the area of authentication methods and tools.
