Narrowband PLC communication for Smart Metering
Kubů, Jiří ; Blažek, Petr (referee) ; Mlýnek, Petr (advisor)
This bachelor project is about narrowband PLC communications. The work describes the basic principle, division of PLC communication, history, technology, utilized communication standards and interference affecting the data communication technology. In this work we also performed experimental measurements in real environments with modems from Texas Instruments C2000 and C2000 TMDSPLCKITV4 PLC PLC TMDSPLCKIT-V3. The results of the measurements are real transmission rate. Moreover application was created for remote data collection along with PLC modems C2000 PLC TMDSPLCKIT-V3, the aime was to edit PLC modem firmware and create applications for receiving data from the terminal.

Ranque - Hilsh vortex tube
Bábor, Lukáš ; Brázdil, Marian (referee) ; Šnajdárek, Ladislav (advisor)
Ranque-Hilsh vortex tube is a device that converts high pressure gas flow into two low pressure flows with higher and lower temperature, than a temperature of the inlet flow. Technically, it is a device of very simple construction, which is characterised by low initial costs, high endurance, durability and low maintenance. Its main disadvantage is low coefficient of performance, compared to conventional heat pumps at room temperature. In the first section of this paper, examples of applications where utilization of Ranque-Hilsh vortex tube is advantageous are given. Afterwards, several theoretical concepts of refrigeration cycles utilizing vortex tube to lower energy consumption are described. The final section of this thesis introduces new geometry of inlet nozzles for improving coefficient of performance of vortex tube. This geometry is then compared to straight tangential nozzles of circular cross-section. During the measurements, surface temperature of the vortex tube with respect to its length is monitored.
