Drug transport using microbubbles
Piňos, Ondřej ; Tancjurová, Jana (referee) ; Rudolf, Pavel (advisor)
This bachelor thesis deals with the research in field of medical usage of microbubbles, specially focused on ultrasound iniciated cavitation of microbubbles filled with drugs. Thesis includes technology of manufacturing, chemical composition, efects of cavitated microbubbles on tissue and description of mechanism that occurs during the aplication of ultrasound triggered microbubbles. Second part deals with mathematical description of microbubble under acustic pressure using the Rayleigh-Plesset equation and equation for microbubble with membrane are presented. The MATLAB script for calculation of physical parameters describing state of microbubble is also explained.

Application of cavitation in industrial processes
Hamar, Oliver ; Tancjurová, Jana (referee) ; Rudolf, Pavel (advisor)
The bachelor thesis deals with the research of the application potential of cavitation technologies in various industries. Thanks to its properties, cavitation seems to be a promising tool for streamlining a large number of industrial processes in several aspects. The first part deals with the theoretical description of the cavitation phenomenon, its negatives and methods of their detection. The second part focuses on the analysis of possible usage areas of cavitation technologies and the ways of generating the cavitation, focusing on current research and findings in the area of hydrodynamic cavitation application.

Methods of indicating chaos in nonlinear dynamical systems
Tancjurová, Jana ; Šremr, Jiří (referee) ; Nechvátal, Luděk (advisor)
The master's thesis deals mainly with continuous nonlinear dynamical systems that exhibit chaotic behavior. The main goal is to create algorithms for chaos detection and their subsequent testing on known models. Most of the thesis is devoted to the estimation of the Lyapunov exponents, further it deals with the estimation of the fractal dimension of an attractor and summarizes the 0--1 test. The thesis includes three algorithms created in MATLAB -- an algorithm for estimating the largest Lyapunov exponent and two algorithms for estimating the entire Lyapunov spectra. These algorithms are then tested on five continuous dynamical systems. Especially the error of estimation, speed of these algorithms and properties of Lyapunov exponents in different areas of system behavior are investigated.
