Influence of breathe to baroreceptor reflex
Humpolík, Tomáš ; Janoušek, Oto (referee) ; Kolářová, Jana (advisor)
This Master's thesis deals with the influence of breathe to baroreceptor reflex. The first chapter is focused on measuring of blood pressure, in reference to later used method. In the second part is detailed analysis and explanation of term baroreflex, relationship between frequency spectra of systolic blood pressure, heart rate and breathing, mechanisms of regulation of blood pressure and heart rate variability. Third chapter deals with possible ways, how to analyze data, which are needed for estimation of baroreflex sensitivity, analyze of heart rate variability and estimation of power spectral density. Next parts of this thesis is paid attention to technical equipment and methods of acqusition of data, using this equipmnent. Part of this work is also software application, which makes possible from the recorded data estimate baroreflex sensitivity.

Water jet cutting of material
Jáchym, Jan ; Fialová, Simona (referee) ; Habán, Vladimír (advisor)
This bachelor thesis describes principles developement and usage of high - speed water jets for cutting. In the first part, it features description water jet cutting technology and its application, basic parts of high pressure system and sorts of generators pressure. In the second part, it divides water jet according to discreteness in time and chemical constitution. In the third part, it deal with studies usage so - called pulse jets, especially at ultrasonically modulated ones. It is described mechanism rise and break up of modulated high - speed jet on individual pulses.
