Wind Influence on the Traffic Airports in the Czech Republic
Švec, Michal ; Hammer, Jaromír (referee) ; Krška, Karel (advisor)
This bachelor’s thesis deals with surface wind, which is the wind that influences or limits take-offs and landings of aircrafts. It firstly mentions the meteorological causes of the wind, its characteristics in the atmosphere, effect of the ground relief to the wind and dangerous meteorological phenomena for aviation, which are caused by the wind. The next part is focused on the wind measurement from the general and practical point of view, which includes today’s measuring instruments. It describes the issue of wind components and their effect on take-offs and landings of airplanes, wind in meteorological reports and forecasts and AWOS system. Afterwards the evaluation of surface wind at Karlovy Vary airport was made using the described scales and methods.

Ultrasonic anemometer
Hůlka, Jakub ; Mágr, Zdeněk (referee) ; Havlíková, Marie (advisor)
This master’s thesis deals with the construction and realization of an ultrasound anemo- meter. Individual types of anemometers are compared in this thesis, including mechanical, thermo anemometer and ultrasound anemometer. Different construction renderings and measurement principles of ultrasonic anemometers are analyzed. In addition, an experi- mental method of measuring the speed of sound by phase shift between two transmitting frequency is described in the document. This thesis includes the design of an control unit and the realization of a simple prototype of an ultrasonic anemometer. Experimental confirmation of the characteristics of the ultrasound anemometer is the last part of the document.

Thermal Mass Flowmeter
Mlčoch, Albert ; Kunz, Jan (referee) ; Beneš, Petr (advisor)
The thesis deals with the design of a mathematical model and practical implementation of a flowmeter based on the thermal principle. The range of the proposed flowmeter is from units of kilograms per hour to lower hundreds of kilograms per hour. The design of the flowmeter is non-invasive to the flow channel, the heating element is located outside the pipe. In this paper, the flowmeter parameters are identified and a temperature regulator is proposed. Measurements are made on a test bench. The results of the measurements are discussed. Modifications to the existing hardware are suggested.

Identifying Anomalies in Industrial Networks: A Proposed Testbed for Experimental Evaluation
Kuchar, Karel ; Blazek, Petr
Not only because of the convergence of InformationTechnology (IT) and Operational Technology (OT) networks, thepass-through network environment needs to be monitored andadequate security implemented. Due to the occurrence of differenttypes of anomalies and their inconsistency in the literature,three main types of anomalies have been identified in this paperand a testbed has been proposed to serve for further experimentaltesting. This testbed was created using an anemometer and inthe current state using an accelerometer. From the results sofar, a correlation between the normal condition and the inducedoperational anomaly can be observed.

Bladeless fan cooling module
Šišpera, Adam ; Vacula, Jiří (referee) ; Bazala, Jiří (advisor)
Tato diplomová práce se zaměřuje na prozkoumání možností implementace bezlopatkového modulu ventilátoru založeného na Coanda efektu v chladícím systému osobního vozidla. Jejím cílem je prozkoumat proveditelnost takového řešení, jeho provozní charakteristiky a stanovit soubor doporučení pro návrh konkrétního designu. Vhodný chladící modul je navržen, následně hlouběji testován a jeho funkčnost je ověřena také reálným experimentem.

Hardware For Ultrasonic Anemometer
Veselý, Vladan
The article describes the development of hardware for a low cost ultrasonic anemometer. The core of the device is a STM32F103CBT6 processor, a part of the Maple Mini development platform. In addition to ultrasonic measurement circuits, meteorological sensors and communication circuits are also connected to the processor. The paper also discusses various methods to excite ultrasonic transducers and to process the received signal; the latter procedure embodies the basis of the designed instrument. All the electronic components are embedded in a self-heating plastic case. The sensor satisfies all relevant safety and weather resistance requirements.
