The effectiveness of mind-mapping learning strategy to extend vocabulary knowledge among elementary students
Šnevajsová, Helena ; Mikuláš, Martin (advisor) ; Kacafírková, Petra (referee)
Knowledge of vocabulary is an essential part of linguistic competence. Many students learn English vocabulary by translation and rote memorisation of vocabulary lists, which can result in the inability to use the words in well-formed sentences and appropriate contexts. Some students may find rote memorisation monotonous. This study examines the effectiveness of using the mind-map learning strategy to extend English vocabulary. Thirty-one elementary school students (15 men and 16 women) from two different elementary schools completed a short test before vocabulary instruction to obtain baseline data. Vocabulary instruction with the use of mind maps learning strategy followed. The recall was measured at the end of the lesson and one to two weeks after vocabulary instruction. A subjective assessment of the mind map learning strategy to learn vocabulary was taken. The results show that the knowledge of vocabulary items improved compared with the baseline. Moreover, students retained similar knowledge even after one to two weeks. New information was moved to the long-term memory of the students. Students were able to recall vocabulary from a medium- term perspective. Subjective assessment of the learning strategy showed that students enjoy learning vocabulary with mind maps more than writing vocabulary...

Control Unit for Autonomous Vacuum Cleaner
Matějů, Jan ; Kopečný, Lukáš (referee) ; Žalud, Luděk (advisor)
This paper is in introduction focused on review of robotic vacuum cleaning and evaluation of available products qualities. However the main focus of this paper is system design of all subsystems, control systems and PCD design of robot electronics. In this paper is also described a method for evaluating approximate distance of robot from the obstacle. There are also described problems of system design of IR proximity sensors. The last part of this work is development of control software for robot and its testing.

Automatization of Analysis of Performance and Power Consumption
Rudolf, Tomáš ; Jaroš, Jiří (referee) ; Nikl, Vojtěch (advisor)
This thesis deals with increasing efficiency of supercomputers. Higher efficiency can be achieved by reducing frequency of processor if the algorithm does not slow down significantly. This thesis presents set of scripts designed to monitor consumption of processor along with scripts that visualize these measured values. It also allows easy control of processor frequency. The created solution gives user a capability to measure given algorithm efficiency and optimize computing power of specific computer exactly for the algorithm. Due to this work the user will be informed about whether it is advantageous to run his algorithm on one or other frequency of the processor.

Datalogger with parallel data logging
Havlena, Marek ; Minář, Petr (referee) ; Zuth, Daniel (advisor)
This Bachelor's thesis is dedicated to the design and implementation of the Datalogger module, which stores data in two different memory storages. First memory storage is solved by using an SD card and the second is the internal EEPROM memory of the microcontroller. It also deals with data synchronization between these memory storages. Communication between the cards is through the SPI bus and communication with the module is provided by a serial interface designed by USB transmitter (UART).

Enhanced mathematical library for C++
Temel, Aleš ; Macho, Tomáš (referee) ; Petyovský, Petr (advisor)
I create a library for storing matrices and working with matrices in this bachelor’s thesis. In this case, the issues concern mainly so-called sparse matrices. C++ do not provide among the standard libraries tools for easy working with sparse matrices. The most frequent alternative is the application of two-dimensional array (2D array). 2D array may be realized as a double pointer representing the rows and the columns of the matrix. The basic problem is that behavior of 2D array is identical both to the sparse, and to the full non-zero matrix. 2D array ignores the possibility to store matrices more favorable. The library for storing matrices designed by me takes into account the storing of sparse matrices by several different ways. It offers the sparse format CSR (Compressed sparse rows), as well as alternatives to save the specially structured matrices. In the course of creating library the main emphasis first of all I put on the amount of memory that is necessary for storing matrices. Because it is a mathematical library, it contains different functions suitable for working with matrices, such as determinant calculation, inverse matrix calculation and so. When calculate these functions it is necessary to take into account used memory size as well. Intermediate results are stored also in sparse format, and removed as soon as possible after their use. I created also the second library that deals with the floating point numbers stored with greater precision than standard data types like float and double. The size of occupied memory increases according to precision of floating point number.

The Working Title: Things I Have Not Done
Bendová, Ivana ; Smetana, Matěj (referee) ; Klímová, Barbora (advisor)
My bachelor thesis deals with the studies at the Faculty of Fine Arts, and with unrealized projects. These are works that remained as ideas in my mind, and that I started but have not yet been fully realized. The material for this work is in the form of texts, these lyrics are slightly poetic memories of my thoughts, the reconstruction of memories, influenced by the current state of my mind. I created a portfolio of my unrealized projects visually looking like the real portfolio, that was required to be produced during the last four years of my studies. The work that I am presenting is a confrontation of those two portfolios like instalation.

Processing of the RC plane model telemetry
Žák, Tomáš ; Fedra, Zbyněk (referee) ; Prokopec, Jan (advisor)
Bachelor’s project focuses on problematic about scanning state of RC plane model, during the fly. In detail there is described internal and external structure, including communication. Main objective of work is design functional board for scanning state of RC plane model, during the fly. There is used akcelerometer for scanning actual state of plane. Accelerometer sends measured data in digital form to microcontroller for evaluating. List of used components is in the enclosure.

Bluetooth cache
Franek, Miroslav ; Háze, Jiří (referee) ; Pavlík, Michal (advisor)
This thesis deals with bluetooth cache design for geocaching. It briefly describes what geocaching is and describes the bluetooth cache. It also describes the selection of hardware for realization, the design of circuit diagram and printed circuit board. Using a flowchart, it explains the firmware function and provides an application management manual for using an Android application for managing the cache. Presents the results of measuring cache consumption in individual modes. Finally, it proposes a solution to extend the cache life for a single charge.
