Smart button for home automation
Matula, Ondřej ; Bradáč, Zdeněk (referee) ; Benešl, Tomáš (advisor)
This thesis deals with the design of a smart button which will be used as a periphery to a smart home. The smart button combines the functions of the standard light switch with the ability to control other devices. The smart button communicates via a wired CAN or PWI bus. Hardware designing process which include selection of a suitable components and most appropriate technical solutions is discussed. Another part of thesis deals with implementing a firmware that allows a smart button to communicate with the master system.

Thermoelectric device with Peltier elements
Klír, Tomáš ; Říha, Kamil (referee) ; Rampl, Ivan (advisor)
This bachelors thesis contains description of particular components of the biological termostat. There is described Thermoelectric effect and Peltier element, witch it use. The text describes the most common methods of temperature measurement. For its management are described basic types of regulators - P, PI, PD, PID and PSD. This work contains the theoretical description and methods for the determination of their parameters. There are also described circuit elements for performance management of Peltier element and microprocessor and a description of control program of the microprocessor.

Measurement of meteorological variables
Škorpík, Daniel ; Harabiš, Vratislav (referee) ; Chmelař, Milan (advisor)
This bachelor thesis discusses about the basic meteorological variables, especially temperature and airflow. These magnitudes are measured using an anemometer which uses resistive sensors, namely, two thermistors of NTC type that described technology, operations, methods of scanning, sensor placement and implementation of such a device. After that was designed block diagram and circuit diagram. The meter is realized, than we describe the individual components and then is calibrated and tested. In conclusion, it is evaluated for use in medicine.

Evolution of PTC bitter taste receptors in West Africa
Holoubková, Tereza ; Černý, Viktor (advisor) ; Macholán, Miloš (referee)
The aim of this thesis is to determine whether the TASR38 gene is under selection pressure in West Africa and if its diversity varies within populations practicing different modes of subsistence. It further focuses on polymorphisms occurring in the gene and their association with sensitivity to the bitter tasting compound PTC. The thesis analyses 147 samples of saliva from three Mauritanian populations in order to sequence the DNA of the TAS2R38 gene exon. Ten polymorphic sites conditioning 16 haplotypes were observed in TAS2R38 gene. Mutations in amino acid positions 49, 262 and 296 occurred in all three populations; all eight possible haplotypes were observed. 94 % of them constitutes major PAV and AVI haplotypes and AAI haplotype, all of which were detected in each of the three populations. Additionally, 14 genotypes were identified in our sample; the most common being those created by a combination of the three haplotypes. Kruskal-Wallis test showed that TAS2R38 genotypes are strong predictors of PTC response in the examined African populations. PAV haplotype is associated with sensitivity to PTC (taster haplotype); conversely, AVI is a nontaster haplotype. At the same time, it was confirmed that PAV is an ancestral haplotype evolutionary closest to the chimpanzee TAS2R38 gene and it probably...

Support - intervention radiology diagnostic methods at liver´s investigation
MÁDR, Robert
The special field of radiology, interventional radiology, is a logical result of the current technological development in medicine. The purpose of interventional radiology is to include the knowledge of clinical, especially surgical, procedures, and a considerable development of imaging methods for treatment some diseases and conditions with minimum damage of the exterior integtiry og human body. This is made possible only by using the current imaging methods based not only on the X-ray radiation but also on ultrasound and magnetic resonace imaging to guiding surgical instruments in body cavities and organs. Intervention radiological methods achieved considerable technological progress expressed mainly in quality and sensitivity of medical examinations which increases the possibilities to make the correct diagnosis and achieve succesful treatment. My thesis deals with liver, gallblader and gall ways diseases and the radiological imaging of these parts of the body. Together with the development of various hepatobiliary system diseases upgrade examination techniques are being developed. The examination techniques include classical radiological methods, endoscopic methods, CT and magnetic resonace imaging and also the intervention diagnostics and hepatobiliary surgical treatment. In the practical section of my thesis I describe the anatomy, pathology, examination indications and examination methods themselves. I also refer to the special instrumenarium {--} a collection of instruments and other equipment for an operation or for a medical procedure. The objective of my thesis was to give a complete survey of interventional radiological methods used by a radiologist in liver examinations.
