Development of European regulation against the abuse of legalization of crime proceeds
Palková, Markéta ; Zemánek, Jiří (referee) ; Tomášek, Michal (advisor)
The purpose of my thesis is to record the development of the legal regulations focused on the fight against the legalisation of the proceeds of crime with particular emphasis on the regulation within the European Union. I have chosen this topic because of the recency of money laundering phenomenon and the missing comprehensive outline of the development of the legal regulations in this area. Money laundering may be loosely defined as all actions and procedures intended to conceal or disguise the source, nature, ownership or real beneficiary of the illicitly gained funds in order to create the impression that the proceeds have a legitimate source. If this process is successfull, illicitly generated funds will seem to be absolutely legal and become easily available for the criminal. The thesis is composed of six chapters. Chapter One is introductory and contains the basic information related to money laundering and illustrates the aims of my paper. Chapter Two consists of two parts which characterises the very concept of money laundering. Part One contains various definitions of money laundering which can be found in law. Part Two describes the three stages of money laundering - placement, layering and integration and shortly demonstrates the methods usually used for money laundering (e. g. smurfing, money...

Mpembe effect - reality or fiction? (Hysteresis by water freezing).
Böhm, Pavel ; Obdržálek, Jan (advisor) ; Rotter, Miloš (referee)
The aim of this thesis was to review theoretically and experimentally so-called Mpemba eect, where the initially hot water freezes sooner than the initially cold one. Based upon already published theoretical and experimental works, a list of circumstances possibly supporting this phenomenon was created and discussed. Some situations were veried experimentally. These experiments were carried out partly in laboratory using small amounts of distilled water (less than 1 ml), partly in "kitchen conditions" using the tap water (about 200 ml) and a commercial home refrigerator. The time of freezing dened by freezing of the entire body of water was measured using the inection points of cooling curves. Unlikely to the Mpemba eect (and likely to the usual expectations), usually the sample of cold water freezes sooner than the hot one. The Mpemba eect occured rarely, mostly when the cooler was covered by the layer of the snow and the hot vessel could melt through it to reach better thermal contact than the cold vessel. Other observed cases were mostly inconclusive.

Evaluation of Long-term Land Cover Changes in the Region of Svitavy
Drahošová, Stanislava ; Štych, Přemysl (advisor) ; Slačíková, Jana (referee)
Land Cover changes in region Svitavy Abstract The aim of this thesis is to evaluate land cover changes of remote sensing data in region Svitavy after 1990. Landsat data (1994 and 2001) and IRS-P6 data (2006) were used. The literature search concerns the spectral characteristics of surface, the image classification and evaluating land cover changes in the Czech Republic. For image classification was used Maximum Likelihood algorithm of supervised method. The parts of image classification are the training stage, the classification stage, postclassification smoothing and classification accuracy assessment. Land cover changes were evaluated by compare area and share of land cover category and overlap of vector layers for 1994 - 2001 and 2001 - 2006. Two programmes were used: PCI Geomatica and the ArcGIS. In my classification were found some errors based on evaluation error matrix. For the whole time period was confirm relatively assumed tendency as growth of grasslands and forests and spreading built-up area in region Svitavy. Keywords: land cover, classification, region Svitavy, Maximum Likelihood

The Segmentation of Ultrasound Images for Artery Wall Detection and Intima-Media Thickness Measurement
Beneš, Radek ; Chromý,, Erik (referee) ; Dostál, Otto (referee) ; Říha, Kamil (advisor)
The thesis focuses on the measurement of intima media thickness, which seems to be a significant marker of the risk of cardiovascular events. Intima media thickness is measured in ultrasound image displaying the common carotid artery in its longitudinal section. In the longitudinal section the intima and media layers are visible. Thesis is discussing both technical and medical background and summarizes state of the art in this field. The main part of the thesis describes the novel automatic system for measurement of intima media thickness. Proposed system includes also robust method for artery localization and therefore is able to process raw B-mode data from ultrasound station without any initialization or manual preprocessing.

Automatic detection of neural fibers losses
Václavek, Martin ; Jiřík, Radovan (referee) ; Kolář, Radim (advisor)
This work is focused on detection of loss in nerve fibre layer on colour pictures of retina, witch are makes by fundus camera. It describe every simple objects of retina, optic nerve head, macula lutea and vascular bed. It detect optic nerve head and his near area, witch is general for detection of breakdownds. It use several metodes of picture adjusting for picture elaboration and objects detection (segmentation, thresholding, enhancement, hough transformation ). The detection of loss in nerve fibre layer is based on comparing of statistic parameters ( average, standart deviation, skewness coefficient and kurtosis coefficient histogram, entropy ) in choosed areas with and withou destruction of nerve layers. Vascular bed have badwatsh on results, cause of this we using hand choosing of essay.

Partly service oriented systems.
Severýn, Tomáš ; Kasal, Jindřich (referee) ; Král, Jaroslav (advisor)
The aim of this thesis is to analyze current state of Service Oriented Architecture, describe maturity of some products on the market and to make forecast of future trends based on gained experience. Service Oriented Architecture is a wide term and may have deep impact on many activities in modern enterprise. Development, which led to this architecture from IT point of view, together with most used standards, is summarized in theoretical part of this thesis. The stress is put on standards connected with process management and integration of human tasks into processes. Practical part of this thesis is focused on feasibility study of creating document management system. It concentrates on analysis of current situation and design of extending the system with external process management. Implementation work was made to prove ability to connect those systems using standards from theoretical part of this thesis. During the implementation were discovered that some components fail to satisfy those standards and therefore it was necessary to make some changes in communication layer. However, the hypothesis that current products are mature enough was proved to be true.
