Some Aspects of EMC Pre-Compliance Testing
Vídenka, Rostislav ; Soldán, Josef (referee) ; Mazánek, Miloš (referee) ; Dřínovský, Jiří (advisor)
This doctoral thesis deals with EMC pre-compliance testing of radiated disturbance. The thesis summarizes present pieces of knowledge about restricting of disturbing ambient signals and focuses on restricting of test site imperfection influence on the measurement results. Pre-compliance test site “calibration” uses comparison signal sources. There were added up the recommendations for “calibration” steps, too. The semi-anechoic vs. fully-anechoic chambers measurements results were compared. Some methods for dealing with ambient disturbing signals were discussed and high attention was applied to the test site choice and the minimal dimension geometry was recommended. There are presented recommendations for pre-compliance radiated disturbance measurements in the conclusion with the stress on available test equipment.

Evaluation of influence of interpolation methods on coregistration of radar images
Slačíková, Jana ; Potůčková, Markéta (advisor) ; Hlaváčová, Ivana (referee)
Evaluation of influence of interpolation methods on coregistration of radar images Abstract SAR interferogram processing requires subpixel coregistration of SAR image pair for accurate phase differencing. Errors in alignment introduce phase noise in SAR interferogram. Last step in coregistration is resampling one of SAR images. Also this step introduces errors in SAR interferogram. The resampling algorithms Nearest Neighbor, Bilinear interpolation, Cubic Convolution and advanced methods such as Raised Cosine kernel, Knab interpolation kernel and Truncated Sinc were tested on ERS tandem data and compared. The results were compared with the theory and simulations of earlier investigations (Hanssen, Bamler, 1999), (Migliaccio, Bruno, 2003) and (Cho ... [et al.], 2005). The main experiment in this work was to examine and compare resampling methods on real data to evaluate their effect on the interferometric phase quality and DEM generation. The coregistration performance was evaluated by the coherence (Touzi ... [et al.], 1999) and the sum of phase differences (Li ... [et al.], 2004). No evidence showed that computationally intensive algorithms produced better quality of interferogram than Cubic Convolution. The possibilities of evaluating by means of the accuracy of the final InSAR DEM (Li, Bethel, 2008) were...

Treating a patient with burn trauma by ERS
SCHLOSSER, Matouš
The topic of this thesis is treating the patient with burn trauma by ERS. This issue is still discussed and guidelines for treating this injury are constantly updated The theoretical part deals with anatomy and physiology of skin as well as burn pathophysiology. This part of work also provides information about assessing burn severity, first aid of burn trauma for laics and treating burn trauma in pre-hospital care by ERS. In the end of theoretical part the differences in treatment between adult and pediatric patients and their transport to specialized center are described. The research part has two main goals. First goal is to find out the level of knowledge paramedics have about burn trauma treatment. The other goal is to find out which equipment is available for paramedics in pre-hospital care and whether it is adequate. Eight paramedics participated in the research. Four respondents were from South Bohemian region and four respondents were from Vysočina region. To achieve these goals a method of qualitative research has been used. Data for the research had been gathered by using semi-structured interview Research found that most of the paramedics have knowledge to adequately treat burn trauma and that equipment in ambulance cars is sufficient.

Electronic Registration of Sales - potential benefits
Slavíček, Michal ; Zídková, Hana (advisor) ; Čejková, Eliška (referee)
The bachelor thesis is focused on a very topical subject. The main goal is to calculate an expected year-on-year change of VAT after the ERS was implemented (compare the years 2017 and 2016) in a sector of catering industry. The next goal is to compare the calculated result with estimation of Ministry of Finance. The first part of thesis is focused on a description of ERS. The second part deals with problems of tax evasion in catering industry. The final part is at first focused on the description of methods and data source, then the calculation of year-on-year change of VAT is made. The result of bachelor thesis is the comparison of estimated year-on-year change of VAT with estimation of Ministry of Finance and finally identify the reasons of deviation.
