Implementation of 400 Gb/s Ethernet PCS layer to FPGA
Kolařík, Jaroslav ; Pristach, Marián (referee) ; Fujcik, Lukáš (advisor)
This master thesis deals with the design of the 400GBASE-R PCS in accordance with the IEEE 802.3bs-2017 standard which defines 400 Gbps Ethernet. The first part of this thesis focuses on general architecture of FPGA and its possible variants for implementation for 400 Gbps Ethernet communication, therefore there is description of those architectures and its resources. The next part describes progression of the Ethernet and its connection to the ISO/OSI reference model. The next section of this thesis is about description of physical layer of Ethernet for 400 Gbps version, after which follows design of PCS unit and its implementation with use of resources of selected FPGA. In the last part of this thesis is description of the simulation of the implemented unit. Achieved results and outcomes of this master thesis are evaluated in a conclusion.

Application for Remote DEVS Modelling and Simulation
Kolařík, Jan ; Kočí, Radek (referee) ; Janoušek, Vladimír (advisor)
This thesis describes the design and implementation of an client-server application. This application is used to remote access to models of systems, which are saved on the server. Application also provides editation of the models and their simulation. In the thesis there is a design of Communication Protocol between the client and server too. For the implementation of the client and prototype of the server was used Qt library. Server is realized as a part of existing simulation core (SmallDEVS), which is implemented by Smalltalk.

Side channels
Kolařík, Jan ; Sobotka, Jiří (referee) ; Martinásek, Zdeněk (advisor)
This Master Thesis deals with the side channels, AES encryption algorithm and the use of neural networks to obtain the encryption key. The first part of this work is focused on the basics of cryptography and attacks on cryptographic module. The second part is focused on electromagnetic side channel attack on PIC16F84A microcontroller with embedded AES algorithm. In this section, the Master Thesis tries to analyze electromagnetic emissions of operation S-Box in AES algorithm and try to find sensitive information to use neural network identify encryption key of the AES algorithm. In conclusion is described the software source code to determine the encryption key, summarized results and discussed ways to defend against electromagnetic side channel attack.

Analysis of the development project for the construction of an administrative building in Brno
Kolařík, Jan ; Šebesta, Petr (referee) ; Šmahel, Milan (advisor)
The aim of this diploma thesis is determine feasibility and profitability of property development project at particular lands in Brno. Solution of problem includes both, the legislative part that determines possibility lands focused on change of territorial plan and the financial part that estimates costs and revenues in project balance and potencial profits for investor, if project will be realized. Main result of this diploma thesis is to answer the question, if property development project should be realized at particular lands in question and estimate future value of lands and project. Diploma thesis \uv{Analysis of the development project for the construction of an administrative building in Brno} is useful for everyone, who needs estimate potential of a land for profit from realization of property development project.

Prediction of resistivity for thick film rezistor
Kolařík, Jaroslav ; Otáhal, Alexandr (referee) ; Skácel, Josef (advisor)
This work deals with issue the thick-film technology. Especially this work focuses on trimming value of resistance thick-film resistors. First part is dedicated to create the thick-film and thick-film resistors, trim technology and trim cuts. Next part is design of thick-film resistor and test substrate with resistors. The following is a description of the production the test substrate. Next part thesis deals with practical creation cuts into thick-film resistors by AUREL ALS300. The following is an experimental part dealing with the simulation of thick-film resistor with different trim cuts in the ANSYS Workbench. The last part is for practical verification of simulations measurement by the FLIR SC660 thermovision camera. At the end are evaluated knowledge of the properties of the trim cuts.

IEEE 802.15.4 standard and its practical realization
Kolařík, Jan ; Krajsa, Ondřej (referee) ; Koutný, Martin (advisor)
The bachalor thesis deals with IEEE 802.15.4 standard, ZigBee wireless communication technology and describes its practical implementation. The main part of this work is the creation of two laboratory tasks using the development kit from Jennic and the ZENA network analyzer. In the laboratory assignments, students become familiar with the properties and structure of the ZigBee standard, as is the range of equipment, interference caused other technologies, and passing data frames and learn how to create simple applications for ZigBee module. Finally, laboratory assignments are measured and in each chapter provides descriptions and results of these tasks.
