Identifikace železničních vozů na základě obrazové informace
ŠEPS, Pavel
This master's thesis focuses on the design and implementation of railway wagon indetification system based on the identifying information on the side of each wagon. It describes the search for the optimal image preprocessing, comparison of OCR services, search for the suitable technologies and evaluation of the quality of the finished application. Part of this thesis also describes existing solutions and the application development and functionality. To obtain the images of the wagons, a photo trap is designed and assembled, which is then located near the train track. A custom neural network was built to find the identifying information and a custom annotation application was developed to create the test and training sets. The final identification application then implements this neural network. It also uses Azure OCR services. It is designed to automate the manual process and is ready for use in real operation.

Iodine status among pregnant diabetic women
Radiměřská, Veronika ; Jiskra, Jan (advisor) ; Límanová, Zdeňka (referee)
Inroduction: The target of practical part was to verify the concentration of iodine in the urine (UIC) and its relation to the other thyroid parameters in the blood of pregnant diabetic women in second or third trimester of pregnancy. Methods: We have measured UIC in 163 pregnant women screened positive for pregestational or gestational diabetes in second trimester of pregnancy. I have worked later with results from 154 of them. Currently, serum levels of autoantibodies against thyroid peroxidase (TPOAb) and thyroglobulin (TgAb), thyroid-stimulating hormone (TSH), free thyroxine (FT4) and trijotyronin (FT3) were determined. Results: Median UIC was 91,15 ug/L (range 67,7-112 ug/l). At 136/154 (88 %) women UIC was lower than 150 ug/L, median 86,95 ug/L (range 64,95-106,4) and at 90/154 (58 %) was lower than 100 ug/L. UIC in the range with mild iodine deficiency (50-149 ug/L) was measured at 117/154 (76 %) women and 19 (12,3 %) values were found in the range of moderate UIC deficiency (20-49 ug/L). No value of UIC was lower than 20 ug/L. At 7 (4,5 %) women were measured levels in the adequate range for pregnant women (150-249 ug/L). At 11 women (7,2 %) was UIC higher than 250 ug/L. Conclusion: At 88 % pregnant diabetic women in second or third trimester of pregnancy was identified UIC values at...
