Camera for biological applications
Jurák, Petr ; Slovák, Jiří (referee) ; Kubíček, Michal (advisor)
This diploma thesis is focused on the design of IP blocks for thermal camera. This termal camera is intended for plant research. The main part of the thermal camera is an infrared detector that detects a frequency in the range of 8 – 14 m. The analogue signal obtained is modified and subsequently digitized. The detector also includes a Peltier device which is designed for both detector cooling and heating, and is controlled by an external signal. The MicroZed development board implements IP blocks. The thermal camera is designed to be controlled from the MicroZed board. Device analysis is first described from the theoretical part to the design of IP blocks.

Model of physical layer of communication system IEEE 802.11ah
Jurák, Petr ; Staněk, Miroslav (referee) ; Polák, Ladislav (advisor)
This diploma thesis deals with the analysis of the IEEE 802.11ah wireless communication system. For such a purpose, an appropriate simulation model in program environment MATLAB is created. The first part of thesis focuses on the IEEE 802.11 standard. Basic blocks of the transmitter and receiver are described. Attention is also devoted on the brief description of considered transmission channels. The second part contains the description of the proposed and realized simulation model in MATLAB. Individual blocks of the simulation model are described in details. Finally, the obtained simulation results are evaluated and discussed.

Signal analysis of spoken consonants
Jurák, Petr ; Staněk, Miroslav (referee) ; Sigmund, Milan (advisor)
The aim of this work is at first to explore the characteristics and problems of the Czech consonants and the speech recognition. Then create a study of the methods used in automatic consonants and then create an algorithm to detect groups of the Czech consonants. The consonants are mainly involved in speech intelligibility. This work mainly deals with segmental description of the speech. Prosodic features are not yet considered.

Phy Simulation Model Of The Ieee 802.11ah
Jurák, Petr
This paper presents a MATLAB-based IEEE 802.11ah simulation model. This short article starts with a brief introduction to the IEEE 802.11ah standard. After that, the complete Tx block (on physical layer level) of the IEEE 802.11ah system is described. It is completely realized in the MATLAB program environment. Finally, its correctness is verified by several simulations.
