Comparison of performance characteristics of rabbits on the basis of different feed rations
FUČÍK, Karel
The thesis deals with the problem of breeding rabbits without breed affiliation in pet breeding. It follows the technology of breeding, reproduction and fattening. Diffe-rent diets were used during fattening, with one group of eight individuals fed fresh forage and another group of individuals, of the same number, fed dry forage. Both groups were fed adlibitum with the same dose of complete feed mixture added daily (to supply the necessary vitamins and minerals for proper functioning of the orga-nism). The monitored individuals were weighed once a week and the data obtained were evaluated. The main objective of this thesis was to assess whether feeding fresh green forage or dry forage has an effect on selected nutritional indicators of meat quality. In addition, weight gain and health status of the studied animals were monitored.

Porovnání vybraných reprodukčních ukazatelů u vídeňských králíků
BRADÁČOVÁ, Kateřina
The bachelor thesis is focused on the evaluation and comparison of selected reproductive parameters in individual breeds of Vienna rabbits. The introduction of the research part is devoted to the origin and domestication of rabbits. The following chapters deal with the anatomy and morphology of the reproductive systems of males and females as well as reproduction itself. Part of the thesis also discusses the genetics of rabbits, and a separate chapter is devoted to the Vienna rabbit. The practical part inc ludes the methodology of the work, which introduces the individual breeds, as well as the comparison and evaluation of selected reproductive parameters between the diffe rent breeds of Vienna rabbits.

Access system with Ethernet interface
Knotek, Martin ; Hynčica, Ondřej (referee) ; Fiedler, Petr (advisor)
The access system with the Ethernet interface is presented in this diploma thesis. Access control system is based on the RFID technology. Each identification unit reads the users card number and sends the request to the server other the network. Server checks the card number and sends the answer. The doors are opened. The first part of this diploma thesis deals with the theoretical description of the access control systems. All used technologies are described in this first part of this work. The second part of this thesis describes hardware design of the RFID identification unit with the Ethernet interface and microcontroller Rabbit. The last part presents designed communication protocol. This protocol supports AES secure communication standard. The control program of the identification unit and to the software design of the database and the server application is made and described in this work too.

Laboratory stand with RABBIT CPU
Váša, Tomáš ; Štohl, Radek (referee) ; Bradáč, Zdeněk (advisor)
This master’s thesis contains design of laboratory stand for learning programming microcontrollers. Stand is equipped with two Rabbit modules, which are connected together over local area network. Exercises are focused on working with basic peripheries as digital inputs and outputs,PWM modulation, serial communication. Exercises are interested in evaluation of matrix keyboard and communication with alphanumeric display controller. With the ability to easy access the Internet some exercises are designed for work with this interface. To these exercises is made a preparation of external peripherals. Through these peripherals there can be can be controlled DC motors, step motor, binary outputs and inputs. Each lab exercise contains an introduction, task, instructions and the flowchart of realized exercise. Instructions are written so that it contains important steps to properly manage assignments. Individual exercises are designed to gradually increasing complexity of exercises.

Wireless access system
Sekyra, Jaroslav ; Honzík, Petr (referee) ; Fiedler, Petr (advisor)
This diploma thesis describes practical realization of entrance terminal, which enables transmission of data thanks to radio module ZigBee PAN4551 and Ethernet module Rabbit RCM3200. This entrance system uses Mifare RFID cards, with whose user will identify at the entrance terminal of the guarded object. Data are sent to server station by radio module ZigBee or Ethernet module Rabbit during demand of entrance. The database of all entrance rights of all users is stored on this server. Data system works up received data and sends them back to the terminal. One part of these data is the information about enabling of user entrance. The database system makes a list of passing through users. In the first part of this work whole conception of entrance terminal is suggested. Then basic demands of each block are described in details as well as their placement in guarded object. Next chapters describe basic function of terminal, electrical scheme, and system of power supplies for the access system. Also individual hardware components are chosen and described. In the on of the last chapter there is flow-process diagram of main loops for individual variants of terminal and interrupts functions from timer, serial link and external input from radio network MC13193 drawn. In the last chapter there is a show of server data application “AccessServer” and his basic description.

Analog 0-10V to Ethernet convertor
Hlúpik, Martin ; Štohl, Radek (referee) ; Bradáč, Zdeněk (advisor)
This Master`s thesis concern with problematic of connection analog sensors with voltage output 0-10V to a ethernet communication network. Due to a quick evolution and an application ethernet nets to industry and building technologies is possible to use this solution for connection remote diagnostics and setting of existing analog sensors without bus communication interfaces on instrumentation level of field bus networks. The converter is based on Rabbit module, which can be used like webserver for setting, calibration and data recording. For purpose of wide converter use the data output will be purvey on ethernet interface by Modbus TCP and on asynchronous serial interface RS232. First part of thesis is aimed on description of existing solutions and introduction with principles of linearization and calibration of A/D converters. Description of communication standard Modbus TCP widely used in industry applications. Second part of thesis describes design a realization of project. Here is described equipment block diagram with detail description of each block and devices used. In the part of implementation is description of device firmware with program function description and control. Last part is engage with module function verification supported with plantz of measurements and tests. The thesis is ended with evaluation results, knowledge and detections found out in development of project.

Ni sensors to Ethernet convertor
Kubíček, Ondřej ; Fiedler, Petr (referee) ; Bradáč, Zdeněk (advisor)
This work deals with hardware and software solution for the temperature converter of the standard rezistance temperature Ni sensors with the output through the Ethernet, driven by the Rabbit microcontroller. First part of this thesis deals with the theory of the temperature measurement. There are introduced basic principles of the temperature sensors. In the next part of the work are introduced communication standard and application protocol Modbus. The rest of the work deals with the hardware concept of the converter, the control program of the converter and the program developed for the PC.

Modulr RGB LED display
Coufal, Miroslav ; Šťastný, Ladislav (referee) ; Bradáč, Zdeněk (advisor)
The aim of this master’s thesis was the design RGB LED display with Ethernet interface. I created a display module, controlled by a microcontroller ATmega 2560-16AU. These modules can be connected via a serial RS485 standard. Ethernet connection is made via plug-in interface that uses the programmable module Rabbit RCM 3200. I documented a proposal. I tested designed device.
