Master thesis is focused on analysis, design and development of information system module for the company XYZ s. r. o. The design of the module’s architecture, application objects identification and the development of the module including the economic evaluation are all based on the requirements acquired from the company. Modul is developed in new JavaScript version and uses modern technologies such as React, Redux, REST, Node.js and MongoDB.

Hlavním cílem této práce je vyvinout uživatelské rozhraní a získávání nezbytných podnikových dat v aplikaci sloužící pro schvalování bankovních plateb za použití moderních technologií a technologií poskytovaných společností SAP. V první části je obecně popsáno téma bankovních plateb, jsou vysvětleny klíčové pojmy a zmíněny některé problémy z této oblasti, se kterými se společnosti a soukromníci v dnešní době potýkají. Dále je popsána architektura SAP S/4HANA, pro kterou je aplikace vyvíjena. V neposlední části jsou zmíněny technologie pro tvorbu uživatelských rozhraní, jenž jsou pro tento vývoj vhodné anebo jsou dnes nejvíce používány. Proces návrhu aplikace popisuje její požadavky, tvorbu prototypu aplikace, jenž vizualizuje způsob zobrazení dat uživateli a návrh datového modelu. Výsledná aplikace umožňuje získávat správná data z databáze, zobrazovat je definovaným způsobem způsobem a nabízí možnost jejich editace a správy.

This thesis deals with security, privacy, and anonymity on the internet. In this thesis are described tracking mechanisms and approaches that are being used to collect and send away users' personal information. Information that leaks using this tracking approaches can be used to identify user, to monitor and analyze his behavior on specific web pages and several leaked pieces of information can be misused (for example the leaked credit card number or password). In this thesis is described and tested the functionality and reliability of several current web add-ons providing the protection on the internet. New security increasing web add-on has been designed and developed to demonstrate a technique, that redefines and wraps the original JavaScript implementation of several functions and objects, the wrapping is executed before the visited web page starts processing the source code. Running the wrapping code at this time will ensure, that no other code in loaded web page will ever have access to the original implementation. This add-on is also well-tested. The final thesis' stage provides a great amount of possibilities to improve implemented add-on.

The goal of this thesis is to optimize the existing energy consumption monitoring system and expand the presentation options for the measured data in a way that would be suitable for large volume of data and a long period of time. Optimization concerns especially data processing and data presentation.

This work deals with Audified Audio Processing System. This embedded system includes an Arm processor running the Linux operating system. At present, parameter control (phantom, gain) is complicated, without feedback. In this work, the creation of server - client application, which will allow easy setting of the mentioned parameters and will show their effect, is described.

This work deals with the planning of teaching and exams schedules at the Faculty of Information Technology of the Brno University of Technology. The goal is to design and create a new web-based information system that will help to create new schedules and allow students to be involved in the planning process. The application will be tailored to the requirements of the faculty, whose detailed analysis forms the first part of this work. The second part deals in detail with the design, implementation and testing of the created application, which was already used in planning the actual schedules.

The goal of this this is to create an information system for the visualization of geographical data. The main idea is to allow users to create visualizations with their own geographical data, which they can either import from files or directly attach their own database system as a source of data and make use of the data in real-time. The result will be a new web information system that will act as a point of contact between users, geographical data, and visualizations.

Internet Protocol Television (IPTV) transmits the television signal over the TCP/IP family of protocols. Its advantages are for example that the transmitting is not only one-way as in the “classical” TV broadcasting, but it can provide feedback such as interactivity. There are also some problems which avoids development, for example low channel capacity of access networks. That is why new methods , for example how to get more efficiency in IPTV transmission, are proposed. The main task of this diploma thesis is to visualize tree structure of relations between nodes in the network, based on understanding of principles of the hierarchical summarization and IPTV transmitting. The nodes in the tree structure provide computing and summarizing of the data in back-way channel. There is the data from the end users in this channel. In the first part of this diploma thesis there is explained the principle of IPTV and its differences as compared with classical TV broadcasting. The part is also aimed for the supported services, advantages and disadvantages. There is explained the compressing data with the MPEG-2 and MPEG-4 standards and problems with transport networks called “last mile problem.” To transmitting data IPTV uses Source Specific Multicast – every user connects to the multicast session with requested TV program. Feedback is provided by unicast. Feedback network uses the hierarchical summarization principle to reduce the data. This problem, connected with RTP, RTCP and TTP protocols, is in the work described as well. There is an international experimental network called PlanetLab mentioned in theoretical part of this work. Proposed structure of new protocol and applications including the visualization for IPTV broadcast, is tested in that network. In the practical part of this work there are discussed possibilities and methods for the visualization and data storage. Because of high availability and flexibility, there were chosen web technologies, such as MySQL for data storage. The tree model is executed by Java. The visualization is solved by web technologies, source code for visualization is dynamically generated by scripts in JSP (Java Server Pages). Graphical output is provided by the vector format SVG (Scalable Vector Graphics) which is created for graphical expression on the internet and in the mobile phones. There were created interactive web application thanks its ability to cooperation with Javascript technology. This application visualizes relation-tree structure of nodes. In this work there are explained basics of all used technologies, there are also given reasons for chosen methods and formats. Examples and interesting parts of solution are mentioned as well.

This thesis describes the design and implementation of information system for company Patrokolos s.r.o., dealing with wireless links for CCTV and security systems. Information system enables its users to record data about custommers, entered into the system and assign them a new contract, they may suggest using an integrated graphical interface. It allows to work with information of produced units. Based on the topology of the proposed contract enabled the implemented system to build configuration skript for Mikrotik OS, which then loaded into the unit. The information system is implemented in PHP 5 in cooperation with the MySQL database system 5.1.
