Serial communication peripheries development in FPGA
Štraus, Pavel ; Adamec, Filip (referee) ; Frýza, Tomáš (advisor)
This bachelor’s thesis is about two peripheries. First periphery creates from input parallel signals one output serial signal. This serial signal contains a start bit, the next are data bits, parity bit and stop bit or two stop bits. Data bits are variables. It is mean their count is set with two input signals called Dat0 and Dat1. We can secure data bits with parity bit. Of course we have choice between even parity bit or odd parity bit. After parity bit there is one stop bit or there are two stop bits. Second periphery realizes I2C bus. This communication is between two devices. First device is called master and creates the communication with second device called slave. For communication there are two bidirectional lines. The first line is called SDA, which is a serial data line and second line is a serial clock line called SCL. Communication begins with a start condition. That means line SDA go from high to low while SCL is high and communication is terminate with a stop condition. That means line SDA go from low to high while SCL is high. The peripheries are programming in VHDL language and implemented in FPGA device. After successful simulation in free software ISE WebPACK the peripheries was realized in the development board V2MB1000 with device XC2V1000.

Meteorological data acquisition and transmission
Holínek, Pavel ; Adamec, Filip (referee) ; Frýza, Tomáš (advisor)
This document is about collection and presentation of meteorological data. To get data was used digital and analog sensors, controled by the microcontroller ATmega16. Meteostation has 2 modules. The first is designed for monitoring of indoor values and displaying data, the second module is for outdoor measurements. Next research was focused on the comparison with other meteorological stations and more expansion options.

Software for field gamaspectrometr
Adamec, Filip ; Richter, Miloslav (referee) ; Čejka, Miloslav (advisor)
This work is about design, implementation, menu and communication with superior system for gamaspectrometer. The first part of the document describes basic principles of measuring of gamma spectra and their processing. The second part describes in basics software core of the spectrometer, handling of the keyboard, graphic and text output. Used algorithms are described, and their implementation. The third part contains analysis of requirements on menu, basic concepts of menu control. Next, it is described how to handle inputs from user, like numbers, date and time, and also how to solve the menu for display of values and for input of values. The forth part describes requirements for communication with superior system (PC), analyses how to do deal with this and reasons for this solution. The conclusion brings all concepts used in the previous chapters and reached goals.

The role of fermions and bosons in magnetic resonance imaging
ADAMEC, Filip
Abstract Currently, there are only partial theories describing the role and application of fermions and bosons in magnetic resonance imaging, but there are no interdisciplinary theories. I believe, that by combining diverse disciplines (physics, mathematics and the medical nature of MR), an interdisciplinary theory may emerge, that can also be used as a material to deepen the knowledge of future or already active radiologists in radiological physics and magnetic resonance imaging. The following objectives have been set for this Bachelor thesis: Global target: Creation of an expert description of the role of fermions and bosons in magnetic resonance imaging using interdisciplinary communication. Sub-objectives: C1: Data processing - physics of elementary particles C2: Data processing - classical form of electromagnetic field theory C3: Data processing - structure of magnetic resonance imaging C4: Data processing - quantum mechanics of protons Due to the goals of this bachelor thesis, the following hypotheses were made: H1: The classical dimension of the physical nature of MR can be created by comparison of the structure of magnetic resonance and the classical form of electromagnetic field H2: The quantum dimension of the physical nature of MR can be created by comparison of the structure of magnetic resonance and the quantum mechanics of protons H3: The role of fermions and bosons in the description of the physical nature of magnetic resonance can be described by the comparative structure of magnetic resonance and the quantum dimension of the physical substance of magnetic with the standard model of elementary particles and their interactions In the introduction to the theoretical part of the work, I dealt with elementary particles, their physics and mutual interactions. Furthermore, these particles were divided into fermions and bosons, which were described in more detail. I devoted another part of the theory to the classical form of the electromagnetic field, where I discussed mainly Maxwell's equations. The next part was devoted to quantum mechanics of particles and at the end of the theoretical part I focused on the medical part of magnetic resonance. The practical part compares the knowledge gained in the theoretical part of this work. The results were divided into two sections, according to established hypotheses. The results of this bachelor thesis point to the relatively crucial role of fermions and bosons in magnetic resonance imaging, thus confirming all three established hypotheses. The results of this bachelor thesis point out the relatively crucial role of fermions (electrons, protons) and bosons (photons, Cooper pairs) based on verified and accepted hypotheses.
