Authentication in Smart Grids
Janáč, Richard ; Šťastný, Ladislav (referee) ; Franek, Lešek (advisor)
This thesis is dealing with the possibilities of authentication of service engineers for Smart Grid network devices. The aim was to select the most appropriate type of authentication security token. Therefore, we examined the main principals of cryptography and described the algorithms used in the security token. At the end of the paper, the main three types of security tokens are compared. Further, the paper evaluates their use in equipment for the implementation of Smart Grid networks and token selection for subsequent processing demonstration applications.

2D ultrasonic positioning
Junek, Jiří ; Šťastný, Ladislav (referee) ; Hynčica, Ondřej (advisor)
This thesis deals with the implementation and evaluation of measuring directional and omni-directional ultrasonic senzors. Control of ultrasonic senzors and computation of a distance is realized by using a microrontroller Arduino Duemilanove. The first part deals with the measurement of directional sensors, their wiring and subsequent processing of the measurement is performed in Matlab. The second part deals with solving of measuring and visualization 2D position omni-directional ultrasonic senzors, implementation trilateration algorithm for calculating x and y coordinates and comparison the used filters. At the end of this thesis also includes a comparison of directional and omni-directional ultrasound and evaluate their applicability for measuring 2D position.

Control of lab models using PLC
Vobejda, Lukáš ; Šťastný, Ladislav (referee) ; Štohl, Radek (advisor)
This work deals with the control of lab models using PLC Rockwell Automation. As well as the use of CompactLogix, RSLogix 5000 programming environment, RSlinx Classic communication environment and software for process visualization such as FactoryTalk View Studio. The first part deals with the description of the models and their connection to a PLC environment. The second part describes and compares programming languages (ladder diagram, function block diagram and sequential function charts). The last part deals with the visualization of both models in FactoryTalk View Studio.

Home security system - base board power supply
Peša, Ondřej ; Šťastný, Ladislav (referee) ; Fiedler, Petr (advisor)
This bachelor's thesis deals requirements for alarm system power supplies and includes familiarization with the issue of charging lead-acid batteries and an explanation of the basic principle activity step-down switched – mode power supply. The main goal of this project was to design and implement a functional model of the power supply with lead-acid battery. The power supply includes a battery charger circuit, which when accompanied by a power failure back-up and circuit protects the lead-acid battery against deep discharge UPS is in normal operation continuously charged. The proposal was developed in the program for PCB design Eagle 6.1.0. Functional model was implemented in a single PCB, which together with the battery and transformer were placed in the box.
