Intrusion Detection and Prevention Systems
Černý, Michal ; Vymazal, Michal (referee) ; Pust, Radim (advisor)
The detection and intrusion prevention systems could be realized as independent hardware or set in the software form on to the host. The primary purpose of these protective elements is the undesirable activity detection such as integrity intrusion of the files, invalid attempts while connecting to the remote service or acquisition of the local network data. The systems react to the event on the basis of the action that is defined by internal rules. We can include the caution sending or communication blocking among possible counteractions. The base principals of the detection and intrusion prevention systems are described in the dissertation. Various types of captured data analyses and processes of the inhere rules creation and further more caution formats are mentioned in the dissertation. There are also considered the alternatives of their location including advantages of selected situations. There is described the installation and setting up of particular elements of the realized network and security systems. In order to the verification of functionality and factor of the protection providing there was realized several selected types of attacks.

Solution of modernization technology of part air-pump
Černý, Michal ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
The subject of this thesis is modernization of manufacturing process of air-pump component in a specific company. The work is focused on designing a new variant of the manufacturing process for mass production of the given component. The introduction evaluates the technology of product manufacture and describes the existing technologies of performed prototype production. The second chapter introduces a machine-tool, which will play the existing role of production, which will streamline the productivity of work, reduce the risk of human error and improve the quality of manufacturing accuracy. Further new tools are selected and a new production technology is designed. In conclusion, machine times and an overall design of production are evaluated.

Design of electrical travel of reaper`s drive unit
Otoupalík, Jan ; Černý, Michal (referee) ; Koutný, Daniel (advisor)
This bachelor thesis focuses on the design of electrical travel for universal mowing machine, which will be controlled remotely. Designed travel has independent wheel drive, the maximum speed of 10 km per hour and can be used in the terrain with a slope of 30°. The thesis deals with the determination the parameters of the travel, design of the possible electrical drive units and design with respect to the stability of the device. Another part of the thesis deals with the design of the travel and describes particular parts of the travel.

Utilization of light emitting diode lighting
Podola, David ; Černý, Michal (referee) ; Paloušek, David (advisor)
This bachelor thesis deals with problems of illumination by LED diodes. Basic concepts of lighting technology are defined in the first part. The second part is dealing with the construction of body LED diodes and explains the principle of white light formation to LED. Introduces problems of cooling. Gives an overview of the available power sources for LEDs. Provides an overview of how to control lighting by using motion sensors and presence sensors. Will be made basic economic balance sheet, which will evaluate the advantages of using LED sources. Attachments provide the LED catalogs of manufacturers, accessories for LED and comment on other sources of information.
