Explorative Source Code Editor
Šomlo, Ivan ; Jirák, Ota (referee) ; Křivka, Zbyněk (advisor)
The thesis discusses the tools commonly used by developers in exploratory environments of languages Smalltalk and Self. These languages free their users from using plain unstructured source code. Moreover, they contain tools with richer features. The thesis consists of an analysis, a design proposal, and a description of Object Viewer, a Self based tool designed for languages C and C++. The tool graphically displays fragments of a program (objects and pointers) and allows for manipulating them during debugging. The conclusion consists of a summary and a recommendation for additional new features.

Selected Fractal Algorithms and Their Use
Michálek, Bedřich ; Španěl, Michal (referee) ; Herout, Adam (advisor)
To read up on the problems of fractal algorithms, to program a simple demo application of this algorithms and propose alternatives of a further study was the goal of my project. Since the subject of fractals and fractal algorithms is very extensive, I concentrated on three specific types of them - the Mandelbrot set and the Julia sets related to it, iterated function systems with application of different algorithms for generating, and the stochastic fractals and their utilization for grass, shrub and plasma modelling. I tried out for a certain rate of their optimalization, acceleration and the comparison of time and memory requirements in my study and application although it is not ever possible due to the characteristic of the given fractal type. I also theoretically present some utilization options of the SSE technology for the acceleration of fractal algorithm calculations. The demo application is proposed in the very easy way because there was not the goal to programme a new carefully worked-out software, but rather to try to implement the read up algorithms. For this reason I focused on the clear implementation of these algorithms to be their utilization easily possible. The application is written in C/C++ language with SDL library used to handle the graphics output.

Ionogenic fluorescence probes in research of colloidal system
Střondalová, Hana ; Burgert,, Ladislav (referee) ; Mravec, Filip (advisor)
This diploma thesis studied the interaction of ionic and amphiphilic fluorescent probes with polyelectrolytes. The research of such colloidal system could be helpful in deeper understanding of interactions between polyelectrolytes and surfactants. The aim of this thesis was to determine whether ionic or amphiphilic probes are suitable for this research. Two polyelectrolytes, sodium polystyrene sulfonate and hyaluronan were used in this study. Interactions of polyelectrolytes with fluorescent probes (4-Di-2-Asp, methylene blue, dodecyl acridine orange, DiO and DiA) were studied in this work. Then cationic surfactant cetyltrimethylamonium bromide was added to this system. Samples were studied using fluorescence and UV/VIS spectroscopy. Emission and absorption spectra of these probes were recorded. This experiment was based on hypothesis that due to positive charge these probes will bind to the negatively charged polyelectrolyte. Formation of dimers or other aggegates was presumed for fluorescent probes dodecyl acridine orange and methylene blue. When 4-Di-2-Asp was used,changes in fluorescence intensity and absorption spectra in connection with possible formation of aggregates was supposed to be observed. It should be noted that formation of dimers for 4-Di-2-Asp is not described in literature. The formation of dimers wasn't clearly demonstrated during the measurement. Formation of dimers was observed only with dodecyl acridine orange. Probes DiO and DiA were used only in the study of the interaction with polyelectrolytes. These fluorescent probes showed up as inappropriate, because they adsorbed on tube walls. When cationic surfactant was added to hyaluronan-fluorescent probe system, surfactant pushed away fluorescent probe and bonded electrostatically to negatively charged groups of polyelectrolyte.

Hledání zpravodajství z lidských zdrojů: Měnící se role HUMINT v rámci americké zpravodajské komunity po 9/11
Lochovský, Jan ; Bureš, Oldřich (advisor) ; Schmidt, Nikola (referee)
Diploma thesis tracks changes of approach to the clandestine human intelligence collection (HUMINT) as part of a wider process of the United States Intelligence Community reform after the September 11 terrorist attacks. Using longitudinal comparative analysis, the author observes which key factors enabling successful HUMINT collection were significantly improved and which were neglected, thus constraining a highly desirable development of this intelligence collection technique so important in combating asymmetric threats such as terrorism. Following factors were identified as critical in improving HUMINT: institutional anchoring of HUMINT, adaptation of operational techniques to successfully monitor decentralized terrorism, 'dependence' of the US intelligence community on technological means of intelligence collection, and availability of qualified and especially linguistically adept intelligence professionals in responsible agencies. Keywords CIA, DIA, HUMINT, intelligence, reform, terrorism, United States of America
