Abstract: This master's thesis addresses the issue of surveillance and the right of access to protected zones. NFC technology was selected as a solution for identifying and monitoring sliding doors. The monitoring system is connected to the web server via an Internet connection, which enables easier data processing and more straightforward data access. In this master's thesis, a scaled sliding door model was used that was made using a 3D printer. The thesis also addresses the issue of powering the system using an uninterruptible power supply (UPS) system in the event of a power outage. The monitoring and control system is designated and implemented as a modular system consisting of a UPS, NFC, and the main module. The UPS module powers the system and ensures an uninterrupted power supply. The NFC module is used to communicate between the user of the NFC key and the system. The main module is intended for processing the data received from other modules and components in the security system, managing the sliding doors, and sending the processed data to the controller.

Abstract: Teaching and learning with computers (ICT) encompasses her help in educational process everywhere there where is this perhaps and reasonable. Using ICT as educated accessory mean search of optimal elements for teaching efficiency and for better achieving teaching objectives. Learning process of science, mathematic and technical subjects in elementary school in many situations demands practically and problem solved work. Conceptual learning of physics is computer based and its strategies lead pupils to a better understanding and use of more difficult processes (thinking, inferencing, using the knowledge). By conceptual way of learning we used "fizlets" as simulatory models. They are interactive materials, where processes happen in certain intervals and there is interaction between the model and the pupil. The main goal of study was to research the effects of conceptual way of learning in comparison with traditional classroom education when teaching the topics "Pressure and lifting power" in the eighth class of primary school. We tested four thinking processes of pupils (knowledge, analyses, inference and comparison). The main expected ascertainment of research was that the pupils, who were taught through the conceptual way achieved better results than those who were taught traditionally in the classroom. Hypotheses were confirmed. In general this article will show other users of teaching physics and science some didactic manners of preparing interactive educated materials.

Abstract: This paper describes a new communication protocol named XMC which is designed for the transmission of messages between an embedded device and a remote system. A new markup language called XMDD has also been developed and is used to describe the functional profile of the embedded device. The main advantage of the XMC communication protocol is its flexibility and independence from the device type. It is suitable for communication with devices that have a curtailed amount of working memory (a few kB) and limited computing power, i.e. 8-bit or 16-bit microcontrollers. Messaging between the embedded device and the remote systems is done without any interference with the basic source code of the embedded device, thus allowing access to all functionalities and features of the connectable embedded device and is based on the functionality dictionary and built-in features of an embedded device. It also maintains a low production price for the embedded device and from the programming point of view provides a transparent and flexible upgrade of the hardware and software without any redundancy input.
