Real-Time Liquid Lens Focusing
Zaťovič, Martin ; Drahanský, Martin (referee) ; Rydlo, Štěpán (advisor)
Rýchlosť zaužívaného prístupu k zaostrovaniu kamerových systémov naráža na úzke hrdlo - mechanický pohyb motora, ktorý mení vzdialenosť šošovky od obrazového snímača kamery. Technológia tekutej šošovky sľubuje riešenie tohto problému elimináciou potreby mechanického pohybu. Systémy ktoré ju využívajú sú teda podstatne zrýchlené. Cieľom tejto práce je potvrdenie, alebo vyvrátenie týchto tvrdení a v prípade ich potvrdenia zistiť do akej miery je tekutá šošovka schopná zrýchliť systémy, ktoré ju využívajú. Pre testovanie zrýchlenia implementujeme automatické zaostrenie na základe spracovania obrazu a spustíme ho na kamerových systémoch, ktoré využívajú tekutú a elektromechanickú šošovku. Automatické zaostrovanie na základe spracovania obrazu počíta skóre ostrosti zhotovených obrázkov a hľadá jeho maximum pri rôznych hodnotách zaostrenia.

Image analysis for correction of electron microscopes
Smital, Petr ; Schwarz, Daniel (referee) ; Kolář, Radim (advisor)
This thesis describes the physical nature of corrections of an electron microscope and mathematical methods of image processing required for their complete automation. The corrections include different types of focusing, astigmatism correction, electron beam centring, and image stabilisation. The mathematical methods described in this thesis include various methods of measuring focus and astigmatism, with and without using the Fourier transform, edge detection, histogram operations, and image registration, i.e. detection of spatial transformations in images. This thesis includes detailed descriptions of the mathematical methods, their evaluation using an “offline” application, descriptions of the algorithms of their implementation into an actual electron microscope and results of their testing on the actual electron microscope, in the form of a video footage grabbed from its control computer’s screen.

Silently listen to one's own being: Relationship of bodily sensations and sense in the early philosophy of M. Heidegger
Žitník, Filip ; Pětová, Marie (advisor) ; Novotný, Jaroslav (referee)
Title: Silently listen to one's own being: Relationship of bodily sensations and sense in the early philosophy of M. Heidegger Author: Bc. Filip Žitník Department: Department of general anthropology, FHS - UK Supervisor: Mgr. Ing. arch. Marie Pětová, Ph.D. Abstract: Master thesis Silently listen to one's own being: Relationship of bodily sensations and sense in the early philosophy of M. Heidegger deals with the question of possibility of discussing the motive of body and bodily sensations within the framework of M. Heidegger's fundamental ontology and finding a relationship between bodily sensations and sense within this conception. The first part of the thesis demonstrates through the exposition of worldhood as the existential trait of Dasein that Dasein as ,being in the world' is necessarily bodily being, otherwise the world which is the whole of references would disintegrate. The second part reveals the necessity to conceive the bodily sensations in relation to state-of-mind (Befindlichkheit) as a fundamental trait of this being and not as the mere concomitant phenomenon. Thus the bodily sensation is via state-of-mind (Befindlichkheit) co-constitutive trait of original phenomenon "there" which is in its nature a temporal unity of the traits state-of mind, speech and understanding. In this way the bodily...

Work motivation of employees in helping professions in the ARPIDA Centre, and the Libnič Home and Empatie Centre
DRDOVÁ, Ivana
Work motivation of employees in helping professions in the ARPIDA Centre, Libnič Home and Empatie Centre The thesis solves the motivation problems in choice of helping professions. In theoretical part I dealt with a question what is the mason for a person to perform helping professions.This job is of considerable attraction that can be the reason why an employee can perform this exhausting work even at lower financial evaluation than what is offered at some other professions. Important is that helping is undoubtedly meaningful activity for lots of people. Helping person concerns important life questions and problems of real people. The aim of practical part is monitoring of satisfaction in people working at state( Libnič Home and Empatie Centre) and non-state (Arpida Centre) institution including system of burn-out prevention. Supposed hypotheses: 1. Workers of monitored centers are despite of their lower financial evaluation satisfied with their jobs. 2. Motivation for choice of helping professions are the same both in state and non-state institutions. 3. Workers of monitored centres are informed on rules of psychohygiene in performing the helping professions. The research confirmed first and third hypotheses. The second hypothesis was not confirmed. In order to prove the hypotheses I used a form of quantitative questioning. The data collection proceeded with questioning method, technique of questionnaire. This thesis could be used at organizations where monitoring was carried out. It also can serve as a manual for people working in helping professions and centres of social service.
