Measurement module with simultaneous-sampling A/D converter
Křížek, Miroslav ; Beneš, Petr (referee) ; Havránek, Zdeněk (advisor)
In this work is designed programme unit for acquisition analog acoustic signlas from sensors. There is used accurate A/D converter ADS1287 by the company Texas Iinstrument with resolution of 24 bits to digitizing these signals. There is used 32-bit microprocessor AT91SAM7S64 by the company Atmel to control this A/D converter and sending digitized data to PC. This microprocessor has implemented USB interface. By force of developmental programme units whit microprocessor and A/D converter is produced programme for microprocessor in developmental setting IAR Embedded Workbench IDE 5.0 and simple aplication for PC in setting Borland C++ Builder. Both of those programs are in language C++. Rate of sampling is 26 kHz. On the basis is realized programme unit USB-ADC whit microprocessor and A/D converter.

Stellar mass-loss in the dynamics of galaxies
Křížek, Miroslav
Title: Stellar mass-loss in galactic dynamics Author: Miroslav Křížek Department: Astronomical Institute of the Charles University Supervisor: RNDr. Bruno Jungwiert, Ph.D., Astronomical Institute - Academy of Sciences of the Czech Republic, v.v.i. and University of California - Riverside Supervisor's e-mail address: bruno@ig.cas.cz Abstract: We present an implementation of the statistical approach to the stars-gas mass exchange cycle into the N-body code. First, we summarize available data on stellar mass-loss and derive the time-dependency of the mass-loss rate of a single stellar population. Since the adopted probabilistic scheme that served as a basis for our implementation was limited to the linear star formation law while observations seem to suggest a non-linearity, we derive the non-linear star formation scheme. Both sides of the mass exchange cycle are then implemented into the code with stellar and gaseous particles and compared with an analytic recipe to test their reliability. In the next step, the comparison of such an extended statistical approach with deterministic scheme is performed for a fully dynamical model. The aim of such comparison is to explore divergence between both models of different natures. As illustration of the code application and sensitivity of the resulting galaxy disk...

Stellar mass-loss in the dynamics of galaxies
Křížek, Miroslav ; Jungwiert, Bruno (advisor) ; Šolc, Martin (referee)
We present an implementation of the statistical approach to the stars-gas mass exchange cycle into an N-body code. First, we summarize available data on stellar mass-loss and derive the time-dependency of the mass-loss rate of a single stellar population. Since the adopted probabilistic scheme that served as a basis for our implementation was limited to the linear star formation law while observations seem to suggest a non-linearity, we derive the non-linear star formation scheme. Both sides of the mass exchange cycle are then implemented into the code with stellar and gaseous particles and compared with an analytic recipe to test their reliability. In the next step, the comparison of such an extended statistical approach with deterministic scheme is performed for a fully dynamical model. The aim of the comparison is to explore divergence between both models of dierent natures. As an illustration of the code application and sensitivity of the resulting galaxy disk dynamics, several comparisons with varying the key parameters are performed.
