Remote data acquisition systems
Svadbík, Vít ; Zeman, Václav (referee) ; Mišurec, Jiří (advisor)
This work construes usage phone lines, system GSM and GPRS, internet and communication after high - tension lead in systems of remote gathering data. With development automated running shoot up need acquisition actual indications about all sorts of quantity. Acquisition these information often action on big distance. Systems for gathering from extensive region mark like „remote data acquisition systems". In first part of this work is accentuate on possibility usage as above channels at remote deduction gauging arrangement. In second part are mentioned counts real metering carrier rate and noise narrowband communication PLC. At the close is state instance usage some circumscribed ways transmission data for meter reading electrometer in municipality Boršice u Blatnice.

Web application for getting location of IP nodes
Modrák, Zdeněk ; Kubánková, Anna (referee) ; Komosný, Dan (advisor)
Thesis deal with geolocation in internet network. There are described possibilities of geolocation and thesis is mainly focused on passive geolocation methods. Under passive geolocation belongs location databases which there are described as in theoretical way as used in practical part of thesis. In practical part there is created complex system for geolocation in internet environment which used paid and free geolocation databases. Another used database is WHOIS. Data from paid databases is processed and accuracy of databases is evaluated.

Digital room thermostat controlled via internet
Bača, Martin ; Fuchs, Michal (referee) ; Dvořák, Jiří (advisor)
This diploma thesis deals with the ideological design and realization of digital room thermostat and a temperature sensor selection. The device is designed as three units communicating wirelessly. Outdoor unit and control units sensor provide data for the control circuit of microcontroller ATmega16. Microcontroller choose the boiler operation based on senzor data. Thermostat can be remotely controled

The remote control workplace of electrochemical sensors
Cieslar, Jakub ; Šteffan, Pavel (referee) ; Adámek, Martin (advisor)
This master’s thesis deals with the design of automated workplase for measurement with electrochemical sensors. Design and realization of a device, which communicates with computer and which can be controlled via WAN or LAN nets, are the main aims of this work. This thesis describes the process of designing, realization and optimalization of designed preparation adjustment. It also describes created software of a device, driver for service PC and programme of a web client.

Web interface for on-line administration of laboratory tasks
Belko, Jakub ; Rozsívalová, Zdenka (referee) ; Frk, Martin (advisor)
The present work describes the current trends and e-learning methods using the Internet in the educational process on Czech and foreign universities. The main objective is to create a web interface for on-line administrations of laboratory tasks named "Laboratorě UETE". Practical work is focused on programming web applications and modules for management of instrumentation for laboratory protocols administration including implementation of the IP video cameras outputs and sensor atmospheric conditions. An integral part of this work is to create a module for simulation of physical quantities using commercially available software components based on client – server system.

Anonymous communication in Internet environment
Pajtinová, Mária ; Malina, Lukáš (referee) ; Hajný, Jan (advisor)
Master´s thesis focuses on certain possibilities of how user can anonymously commununicate through the Internet. There are described following anonymous programs: TOR, JAP, I2P and CyberGhost, which allow user to hide his own identity to other IP address. Subsequently, measurements from different technologies are made by anonymous program TOR for calculate transmission speed.

Modern conception of virtual class system
Outěřický, Pavel ; Průša, Zdeněk (referee) ; Pfeifer, Václav (advisor)
This thesis is focused on problems of an interactive distant education with usage of virtual classroom as a software communication tool. The short analysis of types of human communication and education is followed by a description of virtual classroom systems in a very basic point of view like what the virtual classroom is and what its usage is and what advantages these systems have. Furthermore, potentialities and supported tools and functions of today’s commercial and also non-commercial products are described including illustrative examples and focus to potential types of network communication implementation. Next section of the thesis presents possibilities of virtual classroom software development as completely web-based application or as desktop application where usage of different programming languages is considered. After that, videoconference as a often used tool in virtual classroom is described and its demands on the ways and types of realization and implementation are stated. The second part of this thesis creates about three quarters of whole document and is dedicated to description of my own realization of virtual classroom system as a built-in-java desktop application communicating across a built-in-java server desktop application. The first section of this part introduces a basic design and concept of the system including its implemented tools for the distant education. The following chapters describe in details each implemented tool and function from the potential user point of view and also developer point of view.

Student information WWW system
Šír, Michal ; Fiedler, Petr (referee) ; Bradáč, Zdeněk (advisor)
My work contains a classification of a single editorial systems, possibly used during the Advertisement and the Auction system. There is a resolution of creation of the Advertisement and the Auction system, which should be used by the VUT in Brno city. The system is proposed to keep up design of the official internet pages of VUT Brno. A part of this document is generator of the administrative systems, able to generate the internet web pages to repair the small and middle MySQL databases.

Temperature scanning with Web site presentation
Svoboda, Vít ; Vyoral, Josef (referee) ; Kacálek, Jan (advisor)
This master’s thesis solves design and realisation of device for temperature value scanning. First chapter introduces reader into basic principles of transmitting data over inetrnet. Next, the conception of whole designed system is described. Third chapter treats about suitable types of hardware to complete the system. Fourth and fifth chapter describes coherent vision of software realisation for values scanning and their storing into database. Last part attends to implement the dynamic web pages.

System for testing the robustness of communication unit LAN of remote data acquisition
Mlýnek, Petr ; Zeman, Václav (referee) ; Mišurec, Jiří (advisor)
Remote data collection systems are widely used. One of the area is also data collection in energetics, where the energy consumption can be collected daily and presented to users on-line. The advantage of the remote data collection is possibility of frequent readings without a physical presence at the electrometers. The data transmission over the Internet can be subject of various attacks, which is the disadvantage. The understanding of attack method is the most important thing. The protection against the hackers is not complicated, but requires lot of attention. This master's thesis is focused on testing security of the communication unit LAN of remote data acquisition against attacks from the Internet. The next aim of this thesis is to describe algorithm of particular attack, needed recourses for their realization and method of their measurement and evaluation. Communication unit and component composition for attacks simulation is described in the first part of this thesis. The next part is focused on scanning for hosts and ports. The main part of this thesis is focused on the denial of service attacks and man in the middle attacks. In the end of my thesis is described selection of cryptographic system for remote data acquisition and is showed possibility of authentication mirroring. Problems of physical security are described too. The result of this thesis is script implementing all attacks, which are described.
