Digital I/O card with USB communication
Kořínek, Milan ; Holek, Radovan (referee) ; Macho, Tomáš (advisor)
The thesis deals with the design of digital I/O card with USB connectivity for Honeywell spol. s r.o. – HTS CZ o.z. company. The main objective is the delay elimination between reading the current state of the inputs and outputs setting which occurs on the actual used commercial card. Further initial analysis outlines possible solutions at the beginning of the work. One of chapters describes USB communication interface, including its com- munications protocol and USB driver implementation on the operating system Microsoft Windows. The digital card has four I/O ports consisting of eight lines. All ports have built-in protection against overcurrent and ESD protection. Digital isolator is used for USB. Power is supplied via USB, but it is optionally possible to connect an external power source. The last part of the thesis is focused on the card driver design.

Evaluation of patient dose in mammography
Polášková, Markéta ; Sekora, Jiří (referee) ; Kolářová, Jana (advisor)
Breast cancer presents serious epidemiological problem, in result of which die more than 2 000 czech women every year. Screening mammography is one of the most expanded and most effective examinations for early detection of this desease but one has to take into account an inconsiderable risk connected with the procedure based on X-ray ionizing radiation. This diploma thesis deals with evaluation of the dose absorbed by the tissue. It contains the description of evaluation of the average dose in glandular tissue on PMMA phantom, as well as results of the measurements on conventional and digital mammograph. A data file with exposure parameters from mammography screening is included and interpreted. Also the Monte Carlo method was used for the dose evaluation, the thesis contains the brief description of the method, concept of analysis model in mammography and results of simulations.

Barriers to free movement of workers within the European Court of Justice
Mijičová, Petra ; Grmelová, Nicole (advisor) ; Štěpánek, Petr (referee)
Diplomová práce se zabývá existujícími překážkami v oblasti volného pohybu pracovníků. Ustanovení SES, která tuto problematiku upravují, jsou však mnohdy příliš obecná, a až judikatura Evropského soudního dvora interpretací článků SES blíže specifikuje a definuje jednotlivé pojmy, které mohou být komunitárního charakteru (např. pojem ?pracovník?).Proto se tato stať věnuje překážkám volného pohybu pracovníků na základě rozsudků Evropského soudního dvora a rozboru důsledků, které z jeho rozhodnutí plynou.
