Control of Pixel Front Lighting
Kostelník, Pavel ; Vochyán, Josef (referee) ; Dřínovský, Jiří (advisor)
This master’s thesis presents new tendency in automotive lighting – matrix LED headlamp. This thesis consists of description of matrix headlamp construction, main functions of matrix headlamp and controlling by using new integrated circuit, developed by ON Semiconductor Company. The aim of this project is concept of algorithm, which provides correct function of integrated circuit. A part of this thesis is to develop and assembly evaluation kit with this integrated circuit, which will be use to present integrated circuit for customers.

Speech intelligibility index
Kostelník, Pavel ; Šebesta, Vladimír (referee) ; Sigmund, Milan (advisor)
This bachelor’s thesis presents evaluating of speech intelligibility in environment with noise. There are described two methods to reach this purpose – articulation index and speech intelligibility index, according to relevant standards. Part of this thesis deals with measurement of sound pressure to calculation sound pressure spectrum level. The last part of this work includes voice recordings of eight people and noise recordings of moving car in interior for different situations and their processing and evaluation.
