Modern turboprop engine for aircraft to 5700kg MTOW
Košař, Miroslav ; Nastálek, Ondřej (referee) ; Šplíchal, Miroslav (advisor)
This bachelor’s thesis contains a database of available turboprop engines with power up to 2000 kW for aircraft with take-off weight of up to 5700 kg. It briefly mentions basic information about turboprop engines. The main part contains an overwiev of chosen engines and their comparison in the form of tables and graphs. Furute predictions are briefly mentioned in the ending.
Control system for cantilever gates
Koždoň, Ondřej ; Arm, Jakub (referee) ; Bradáč, Zdeněk (advisor)
The goal of this bachelor's thesis is to design a battery powered control system for wireless controlling swing gate (may be used for cantilever sliding gates or garage doors). This system is designed as a small electronic system with necessary Inputs/Outputs (I/O) and an Input for charging a battery from solar cells. The result of this bachelor's thesis are two main PCBs with dimensions of 5×5cm for controlling the gate and remote controller with dimensions of 2,3×4,4cm. Main PCB allows adding more remotes, deleting all remotes and modes for the way of controlling the gate (opposite direction, open only, close only, open wing, close wing, stop the gate) and selecting Master/Slave gate. Communication works on frequency of 434MHz.
An analysis of operation of a family house PV system with electrical energy accumulation
Hroděj, Daniel ; Charvát, Pavel (referee) ; Jaroš, Michal (advisor)
This bachelor's thesis deals with a photovoltaic system of family house using accumulation of electrical energy. The basic characteristics of photovoltaic systems are listed in the theoretical part. In addition, the best known methods of energy storage are compared. The computational part presents the selection and proposal of the system for a particular family house. At the end of the thesis the values of consumption and produced energy are compared.
Assessment of the Impact of Thermal Insulation Performance of a Detached House in the Zlín Disctrict on Running Expenses of this Property
Velísková, Eva ; Uhlová, Eva (referee) ; Weigel, Lubomír (advisor)
Master´s thesis deals with an assessment of investment return in saving precurations. The issue is used on an ordinary detached family house. The assessment is done in more variants to reach an objective comparison of the most advantageous investments. In the first part there is a comprehensive theory explaining the connections of the procedures and the algorithms of the calculations. The second part is calculation, especially from the thermal engineering, energy rating of buildings and the economic return on investment. The third part is an evaluation which, on the basis of the experiences and the results from the thesis, offers a proces show to think in case of intended reconstruction and how to evaluate the efficiency of the investments in the saving precurations.
Electric and Hybrid Vehicles Analysis
Slaběňák, Patrik ; Kuchyňková, Hana (referee) ; Hájek, Vítězslav (advisor)
Nowadays, oil resources start to decrease, therefore it is necessary to think about alternative sources of energy. The result of this semester project is a basic overview of the current development of electric and hybrid cars, with potential application in normal operation and the proximity of their main characteristics, such as mileage, price and service when traveling. The energy required to operate the electric stored in batteries are recharged using the power stations, which is also devoted part of the work. The thesis focuses on the design and calculation of power consumption for a defined route of four-wheel electric wheelchair. The conclusion of the thesis deals with the future development of hybrid and electric vehicles, and with the expected trends in the field of power electronics and motors and with the propagation of hybrid vehicles to the customers.
Energy saving of large objects
Řehák, Pavel ; Brázdil, Marian (referee) ; Pospíšil, Jiří (advisor)
The aim of this diploma thesis is to evaluate the economical measures using own heat and power production using cogeneration units, use of renewable resources to partially cover the consumption of objects, reduction of thermal losses by evaporation in the outdoor swimming pool and overall increase of waste heat utilization by exchanger heat exchangers from flue gas and heat from waste water.
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 .
Home photovoltaic power plant
Brázda, Kryštof ; Brázdil, Marian (referee) ; Pospíšil, Jiří (advisor)
This thesis is focused on evaluation of operational parameters and economic return of photovoltaic power plant installation on chosen family house. In thesis there is elaborated a detailed overview of energy consumption of selected house. The photovoltaic power plant is designed for the selected object. Two possible variants of the system solution with regard to the use of accumulation, sale of surplus electric energy management and procurement priorities.
Everyday life
Rišiaňová, Zuzana ; Janoščík,, Václav (referee) ; Artamonov, Vasil (advisor)
In the form of paint, I illustrate portraits of people on a tablet, taking them from their electronic appearance on social sites, and creating objects in which I install them on a clothes-hanger in the form of jackets.
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.
