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.

Analog 0-20mA to Ethernet convertor
Štreit, Zdeněk ; Štohl, Radek (referee) ; Bradáč, Zdeněk (advisor)
The dissertation deals with a design of an intelligent transmitter of a standard current signal with an Ethernet output port, an implementation of a web interface and Modbus TCP protocol for providing data protection. The introductory part describes standardized analogue technical signals with their possibilities, and characteristics of industrial Ethernet. The subsequent part provides an overview of alternatives to connect analogue signals to Ethernet while using various modules. The thesis continues with a suggestion of an analogue input side of the transmitter in connection with a digital module of Ethernet based on the Rabbit processor in connection with the RCM3200 module. The key part of the dissertation puts forward a proposal of the firmware transmitter and control web interface, shows ways of providing figures measured by the current loop via Ethernet interface for further processing. The final part is devoted to a description of current transmitter ultimate measurement.

Secure access to web interface
Kazik, Milan ; Hajný, Jan (referee) ; Rášo, Ondřej (advisor)
This document contains basic principles and processes regarding secure access to web information system. It consists of theoretic and applied part. These are mainly written together in thesis’s chapters. Theoretic informations were tested on simple web application created in PHP computer language on Apache web server using MySQL database. In the beginning, there is an analysis of used programming environment, especially it’s advantages and disadvantages. The main part of this document is simple characterization of many security problems which can be found on many websites all around the world. In the first place it’s a handling problem of inputs and outputs in the web applications. Password disputableness is solving separatelly. Theory of a problem is analysed first of all. Then a couple of solving methods are suggested and the one which is practically realized is described in detail. There is a notification system created which is used to inform user about errors appeared in web application. In the last section there is a client and server certificates described. This document contains fully characterization of used scripts and connection between them. They are supplemented with many pictures and screenshots which are used to better understanding the disputableness of web security.

Automatic generation of test questions
Cídl, Pavel ; Prokopec, Jan (referee) ; Frýza, Tomáš (advisor)
This project deal with automatic generation testing questions. We will find that turn-key solution problem randomly generation questions. By the help of languages HTML and PHP is created simple application susceptible data access from database: adding, editing, addition entries, etc . System further makes it possible to potluck testing questions of several perimeters and according to type generated test. Next function is generation question and correct answers in size PDF and HTML by the help of system latex.

EDU-mod model control by programmable logic controller S7-1200
Polák, Pavel ; Zuth, Daniel (referee) ; Marada, Tomáš (advisor)
This bachelor thesis deals with creating a few sample solutions to new programmable logic controllers, Siemens Simatic S7-1200. The content of this thesis will serve as support for students of Institute of Automation and Computer Science at the Faculty of Mechanical Engineering. Students can gather information about the performance of new programmable logic, functions and model specified for the education and self-study. Programming tasks are performed using the SCL language. Furthermore, in this thesis describes an extension for HMI touch panels and web server.

Tool for performance testing of web services
Viterna, David ; Šlajchrt, Zbyněk (advisor) ; Pecinovský, Rudolf (referee)
The work deals with the issue of performance tests of web servers, comparing available, free-to-use tools, design their own solution to the problem, its analysis and subsequent implementation. The resulting program is programmed in Java and uses a simple graphical user interface for easy and quick navigation with the option to display the resulting data in a graph. The application allows the user to test the selected web server using an adjustable number of connections with clients virtual connections and delays including advanced settings from headers to the actual JavaScript tests. The result of the test can be a simple overview of all connected together, including statistical data, or a view of individual tests and their representation in the chart. The work contains user documentation and source code.

Approaches to consolidating data base and source code base of the Techno.cz webserver
Stankay, Michal ; Gála, Libor (advisor) ; Kafka, Daniel (referee)
In this diploma thesis, I conduct a research into approaches to consolidating data base and source code base of the Techno.cz webserver, which is the subject of the consolidation. By consolidation I mean bringing the server into the state where documentation is produced according to given requirements, data base is changed in order to improve data structure and consistency and source code base is reorganised in order to unify source code upon one platform, improve file system organization and remove problematic characteristics of the source code in general. The goals of this thesis are to create and describe general process of consolidation, sequence and contents of its steps; to describe contents of consolidation in given areas: documentation, data base and source code base; to describe actual steps made to achieve the final state of the server. My approach to accomplishing these goals is the study of relevant literature and usage of my practical experience in the field of web development. My contribution to the topic is the creation of the general consolidation process that has a potential to be reused by similar projects. Another contribution may be the description of handling the risks and problems that emerged during the consolidation process. This topic may find itself as a valuable source of knowledge for fellow developers facing similar issues. The thesis is divided into eight chapters. After the introduction chapter 2 follows. Chapter 2 describes parameters of the Techno.cz webserver. Chapter 3 discusses software engineering methodologies in order to create suitable consolidation process. Chapter 4, 5, 6 discuss particular fields of consolidation: documentation, data base and source code. In chapter 7 I am trying to assess suitability of created processes and approaches for usage in future development. In the conclusion I summarize the thesis according to required structure.
