Wireless IR sensor for space intrusion detection
Možný, Radek ; Krajsa, Ondřej (referee) ; Škorpil, Vladislav (advisor)
The bachelor thesis deals with design of wireless space breach detection sensor using sensor HC-SR501 and communication module SI4432. In thesis emphasis is on design of device with as low power consumption as possible using sleep modes of microprocessor Atmega328. Thesis includes desighn of temperature measurement, battery state measurement and subsequent broadcasting of gained information to receiving base station. Task of basae station is to evaluate information and among other things decide whether or not is guarded space breached. Two sensor network is further elaborated when sensors are sending periodical notification, person detection alarm, sensor manipulation alarm or warning about low battery state. Base station has regimes guarded and unguarded .

Miniature Tracking Device
Šťáva, Radek ; Levek, Vladimír (referee) ; Macháň, Ladislav (advisor)
The main theme of this masters's thesis is to design and make a miniature universal tracking device. This device is primarily for tracking asset, pets or people. For detecting the position data is used GPS technology. Data transmission is carried out via the GSM network. The device is technically solved and realized with respect to miniature size, high battery life and with regard to resistance against water, dust and impact damage. It is selected unique design, suitable for hermeticaly closure of the entire facility. Due to hermetic closure there is any buttons, any connectors and the battery charging is wireless.

Comparison of energy mixes
Kadáková, Nina ; Milčák, Pavel (referee) ; Baláš, Marek (advisor)
This research type paper is focused on the comparison of the energy mix of Czech Republic with the energy mix of other three states, Slovak Republic, Italy and Norway. In this paper there are described energy sources which the chosen states use for production of electricity. The total installed outputs of the power plants in various years, production and consumption of electric energy and the source ratio for production of electricity are also stated, based on which the final compression is created.

Vehicle thermal battery heat recovery system architecture loop
Stanko, Michal ; Beran, Martin (referee) ; Bazala, Jiří (advisor)
Táto práca sa zaoberá významom a možnosťami rekuperácie tepla výfukových plynov, ktoré pomáhajú pri štarte urýchliť zahrievanie motora a tým znižovať emisie. Teoretická časť pojednáva o emisiach a v snahe znížiť ich o predošlých konštrukčných riešeniach v priebehu rokov. Praktická časť je venovaná vytvorení modelov s implementovanými systémami rekuperácie tepelnej energie a ich dopad na teplotu chladiacej kvapaliny a oleja ako aj na celkovú spotrebu vozidla.

Electric and Hybrid Vehicles
Kosík, Jaroslav ; Mikulčík, Aleš (referee) ; Hájek, Vítězslav (advisor)
This bachelor`s thesis is specialized on obtaining basic piece of electric and hybrid vehicles and their development. The first part of the work deals with electrical vehicles, their history and the possible development of these vehicles can take. In the next section is an example use of electric vehicles in the practical traffic. It is stated these vehicles compared with vehicles using the type of propulsion, such as cars with combustion engines or hybrid vehicles. At the end of chapter is supplemented by specific examples of photographic electrical vehicles. The third part of the work deals with the expected development of electric and hybrid vehicles. There is also a description of hybrid vehicles, and their comparisions with other vehicles using the drive as well as other examples of hybrid vehicles.

Time-frequency analysis of Czech republic gross domestic product
Tráge, David ; Poměnková, Jitka (referee) ; Maršálek, Roman (advisor)
The aim of this master's thesis is to get familier with problematic and concepts of econometrics (GDP, investment, usage and others). We see into used data mainly their characters and expectations and we discuss possibilities of frequention and time-frequention analysis of these data by Fourier and Wavelet transform. Data of quarter development of gross domestic product in Czech Republic, EU and USA will be analysed by the help of programm MATLAB. Data will be filtered by three ekonomic filters: Hodrick-Prescott, Baxter-King and Christiano-Fitzgerald filters. The aim is to find cyclic elements in developments of GDPs and to suggest an optimal type of analysis.
