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.

Computer Remote Control Using Cell Phone
Kolařík, Jan ; Ševcovic, Jiří (referee) ; Pospíchal, Petr (advisor)
The result of my work is an appilcation, which enables to control videos and music by a cell phone, which has an operating system Android 2.1. The application is divided into two parts, the server, which runs on PC, and the client, which runs on the cell phone. For description of managing the applications is used JavaScript.

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.

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.

Operation optimization in wholesale warehouses
Kolárik, Jan ; Pangrác, Ondřej (advisor) ; Hladík, Milan (referee)
The goal of this work is to choose a strategy for given warehouse that will increase the efficiency of its operation. This is primarily about reducing customer downtime and minimizing the distance travelled by handling machines. The final program can generate warehouse structure according to given parameters and then evaluate monitored variables from simulated operations based on optimization techniques used. There is also a planar and spatial warehouse model available, which helps to visualize what is actually happening in the warehouse. The program could serve as an auxiliary tool in the organizing of wholesale warehouse operations and reduce costs required for its operation.

IEEE 802.11 wireless networking for HelenOS
Kolárik, Jan ; Děcký, Martin (advisor) ; Mareš, Martin (referee)
IEEE 802.11 (a.k.a. WiFi) is a popular wireless LAN specification. This thesis documents implementation of this standard within the experimental operating system HelenOS which differs from conventional operating systems with its microkernel-based design. First, the basic concepts of WiFi technology are described. Description of external tools used during development is following. Together with that, the chosen method of integrating the wireless framework into existing system is depicted. In the next chapter we analyse the implementation details of the work. There is thoroughly explained the structure of the driver for selected WiFi device and also the functionality of resulting IEEE 802.11 library. In the end of the thesis there is an evaluation of the features of final work and comparison of enclosed implementation with existing solutions.
