Control Unit for Autonomous Vacuum Cleaner
Matějů, Jan ; Kopečný, Lukáš (referee) ; Žalud, Luděk (advisor)
This paper is in introduction focused on review of robotic vacuum cleaning and evaluation of available products qualities. However the main focus of this paper is system design of all subsystems, control systems and PCD design of robot electronics. In this paper is also described a method for evaluating approximate distance of robot from the obstacle. There are also described problems of system design of IR proximity sensors. The last part of this work is development of control software for robot and its testing.

Autonomous programmer of AVR microprocessors with Ethernet connectivity
Verner, Lukáš ; Daněček, Vít (referee) ; Kravka, Martin (advisor)
he main purpose of this semestral thesis is to get to know programming of Atmel AVR microcontroller, working with SD/MMC cards, working with ethernet (TCP/IP) to create a standalone programmer of AVR microcontroller with ethernet connectivity. The first part deals with the questions of programming theory of memories inside microcontrollers and description of programming algorithm. The most used programming method is called „In System Programming“ - ISP. This method provides easy and fast manipulaton. Concept of this programmer is designed for this ISP method. In this thesis is too explain how to work SD/MMC card and file systém FAT16. This knowledges are necesary to store binary program inside standalone programmer. In final part and in attachments there is hardware design, electrical scheme, bill of materials, printed circuit board.

Information System for Internet Service Provider
Straňák, Slavomír ; Ruttkay, Ladislav (referee) ; Tobola, Jiří (advisor)
This bachelor's thesis describe information system for internet service provider (ISP) with NetFlow technology for monitoring of networks. The thesis characterizes whole NetFlow architecture, individual protocols, their best advantages and frequency application. It specifies detail design and implementation of information system and their basic parts. To achievement this design was applied technology XHTML, CSS, PHP and MySQL, which offer strong implement for making of dynamic application available on network Internet.

Routing among autonomous systems in Internet
Daněk, Michal ; Komosný, Dan (referee) ; Novotný, Vít (advisor)
Bachelor thesis describes the architecture of the Internet, its division into autonomous system and methods of their interconnection. Furthermore extensively describes routing mechanisms among autonomous system but also inside. More space is dedicated to routing protocols OSPF and BGP. At the end of the work is designed laboratory task for subject Network Architecture where this protocols are used.

Universal switch for security systems
T.Kovács, Matúš ; Fedra, Zbyněk (referee) ; Frýza, Tomáš (advisor)
The aim of this work is to discuss the topic of a secure technology device using an electronic securing system and a camera system. The device is using four cameras, from which each is connected to a motion detector. The device is designed so it allows the recognition of a possible failure to the analyzer, damage or arcing fault of the guidance, the switch of the video signal within the vertical blanking interval, or a malfunction of the SMS sending from a GSM modem. Important parts of the device are the VIDEO MUX, which provides the signal from the camera to the screen, and the PIR HANDLER which detects the states of the PIR detector. The work of these peripheries is monitored by the ATmega128 microcontroller.

Customer proprietary information system
Kojecký, Jan ; Roupec, Jan (referee) ; Heriban, Pavel (advisor)
The work deals with the development of custom business information systems for ISPs. The information system consists of two main modules – the user module, which manages all the necessary data and hardware module, which contains information on technical equipment and network infrastructure of company with links to transmitted data monitors. The information system is running on Linux server.

Data flow control in ISP network
Důbrava, Marek ; Jeřábek, Jan (referee) ; Koton, Jaroslav (advisor)
The thesis focuses on the control of data flow in networks of Internet service providers. The problem of aggregation and related overload network elements are shown. Theoretical section describes the standardized methods for managing data flow. The parameters associated with managing data flow are described for devices selected devices. The thesis displays measurements depicting to which extent the ECN algorithm occurs in practice. In the thesis is theoretically described HTB program, which is complemented by a newly described algorithm. The new algorithm is implemented into the program and tested on a real network ISP.
