Data Acquisition from HTML Sites
Komenda, Tomáš ; Šimek, Václav (referee) ; Straka, Martin (advisor)
This work describes scope of creating application for extraction and following data from HTML sites. This work engages in lexical analyze and parsing HTML. This work describes filtration of data from HTML sites. This work describes saving of data in database and XML documents, creating of dynamic HTMP pages, timer cron, GNU utility wget, sending of SMS, sending email and extraction of date from internet. Final chapters describe two web applications. These applications follow data from HTML sites and inform users about changes.

IMAP Proxy for POP3 Mailboxes
Kružliak, Miroslav ; Burget, Radek (referee) ; Kolář, Dušan (advisor)
This bachelor's thesis deals with retrieving e-mails from different accounts on POP3 servers and their organisation in one account on IMAP server. It also studies settings and configuration of IMAP servers in enviroment of operating system Linux. Protocols IMAP and POP3 are briefly compared here from implementation point of view. Further it studies possibilities of periodical start of processes and secure saving of sensitive information. In this part of my thesis main methods of cryptography are shortly confronted.

Web Portal for Network and Application Response Time Monitoring
Bubeník, Martin ; Kaštil, Jan (referee) ; Košař, Vlastimil (advisor)
This bachelor's thesis deals with analysis, design and implementation of a system for network and services responses monitoring. The work is dedicated to two ways of tracking responses, an active one and a passive one. The active mode simulates the realistic requirements for services in the network and it measures time required for the operation. The passive method examines the response of services by means of listening on the network and by network traffic analyzing. Then, both of the methods store all consolidated data in databases. Management of monitoring and display of measured responses is provided by a web interface that allows each user to see monitored objects and to compare responses obtained by the active and the passive monitoring.

Web Portal for Network and Application Response Time Monitoring
Hornický, Pavol ; Žádník, Martin (referee) ; Tobola, Jiří (advisor)
This bachelor's thesis describes the design and implementation of system for the response time monitoring of network services. This thesis describes the basic techniques used for such monitoring, and describes in detail the active monitoring. The core of the resulting system is the automated responses measurement of network services using standard UNIX programs. The web interface gives a clear view of captured responses using rrdtool graphs. The web interface is also used for monitoring management.

Location visualization of sensor units
Hulanský, Jozef ; Verner, Lukáš (referee) ; Komosný, Dan (advisor)
This master thesis deals with wireless sensor network with protocol IPv6. In the begining there are explained the priciples of communication in wireless sensor network, and based on this teories are configured a wireles network with predefined development kit. Furthermore, by using geographic coordinates, positions of the nodes are displayed on a website, what is a part of this thesis. On this website are also presented the measured values from sensors. For saving all informations and measured values about each nodes was used remote MySQL server. Communication between this server and 6LoWPAN network provide Perl script which is runs at periodical intervals. With this method automatization of the whole system are ensured.
