Simulation of action potentials and membrane currents by solving Hodgkin and Huxley equations
Bugnerová, Pavla ; Provazník, Ivo (referee) ; Chmelíková, Larisa (advisor)
The thesis deals with the analysis of the resting membrane potential and action potential mainly on the cell membrane of cardiac cells. Attention is given to the electrical schematic layout of the cell membrane and distribution of current part on the main components. The basis for the creation of a mathematical model and simulation is the differential equations of Hodgkin and Huxley. To the description them of calcium and potassium channel leakage from other models are added. The project explores the possibilities of reproducing the known development of membrane currents in two basic modes (voltage clamp and current clamp). All in user interface MATLAB GUI.
Design of algorithm for anonymization of ultrasound data
Bugnerová, Pavla ; Hesko, Branislav (referee) ; Harabiš, Vratislav (advisor)
This master’s thesis is focused on anonymization of ultrasound data in DICOM format. Haar wavelet belonging to Daubechies wavelet family is used to detect text areas in the image. Extraction of the text from the image is done using a free tool - tesseract OCR Engine. Finally, detected text is compared to sensitive data from DICOM metadata using Levenshtein - edit distance algorithm.
