1	Vizualizace 3D scény pro ovládání robota / Visualization Environment for Robot Remote Control Blahož, Vladimír January 2012 (has links) This thesis presents possibilities of 3D point cloud and true colored digital video fusion that can be used in the process of robot teleoperation. Advantages of a 3D environment visualization combining more than one sensor data, tools to facilitate such data fusion, as well as two alternative practical implementations of combined data visualization are discussed. First proposed alternative estimates view frustum of the robot's camera and maps real colored video to a semi-transparent polygon placed in the view frustum. The second option is a direct coloring of the point cloud data creating a colored point cloud representing color as well as depth information about an environment.

3	Aplikace metody konečných prvků na reálné problémy v hemodynamice. / Application of finite element method to real problems in hemodynamics. Švihlová, Helena January 2013 (has links) The incompressible fluid flow around the geometries of cerebral artery aneurysms is studied in this thesis. The aneurysm is a local extension of a vessel. This disease is dangerous only in the case of rupture. Then the blood is released into the brain. The need of accurate computation of the velocity and pressure fields in this geometries is motivated exactly by the question which aneurysm has tendency to rupture. The finite element method (FEM) is used for the computation of the flow. A good domain discretization is one of the main step in FEM. Modern computed tomography is able to produce series of the two- dimensional images and it is necessary to create an appropriate three-dimensional model of the tissue. This thesis includes the description of the mesh generation and the ways to smooth and improve the meshes. In the theoretical part the equations of fluid flow are formulated. A suitability of a choice of boundary conditions is discussed. Weak formulation for the equations and its discretization are presented. In the practical part velocity and pressure fields are computed by the various finite elements. Wall shear stress which plays an important role in the evolution of an aneurysm is also computed on the introduced meshes. Comparison of mesh smoothing filters, used finite elements and used...
4	Automatické zarovnání CT skenu hlavy / Automatic rotational alignment of head CT scans Karmazinová, Inna January 2020 (has links) The aim of this thesis is automatic alignment of head CT scan. Currently, the alignment is performed manually by an expert, however this process is time consuming. Therefore, methods for automatization of this process are being developed. Two algorithms for alignment in axial and coronal plane were designed based on bilateral symmetry of head. Following an algorithm for alignment in sagittal plane which uses CG-TOB reference line for rotation angle detection. Algorithms were implemented in MATLAB and tested and validated using a database of manually annotated head CT scans.

7	Vara - Framträdande - Värld : Fenomenets negativitet hos Martin Heidegger, Jan Patočka och Eugen Fink. Kasprzak, Krystof January 2017 (has links) The present investigation discusses the phenomenological concept of the phenomenon through an interpretation of the meaning of the negativity of the phenomenon in the philosophical works of Martin Heidegger, Jan Patočka and Eugen Fink. This negativity is thematised in terms of a loss and a privation that leads to a description of the appearing of the phenomenon as a sublime event, which exposes existence to an absence of meaning. A formulation of the absence in question as a dynamic movement of existence opens a new perspective on what it means to do phenomenology: phenomenological thinking does not begin with the immediate givenness of appearance, but through the trembling of meaning in the experience of a loss of the phenomenon. / Denna avhandling belyser fenomenologins fenomenbegrepp genom en tolkning av dess i förhållande till framträdelsen negativa innebörd i Martin Heideggers, Jan Patočkas och Eugen Finks filosofiska författarskap. Fenomenets negativitet tematiseras i termer av ett berövande och en förlust av fenomenet. Förståelsen av detta fördjupas stegvis, och leder fram till en beskrivning av fenomenets framträdande som en sublim tilldragelse. Denna tilldragelse exponerar existensen inför en frånvaro av mening. En formulering av frånvaron ifråga som en dynamisk rörelse av existensen öppnar för ett nytt perspektiv på vad det innebär att bedriva fenomenologi: fenomenologiskt tänkande börjar inte med framträdelsens omedelbara givenhet, utan genom erfarenheten av en förlust av fenomenet som skakar om den givna meningen.

8	Steal me your €motion / Steal me your €motion Rygálová, Monika January 2021 (has links) The text deals with ways and methods of creating my diploma thesis called Steal me your €motion. The diploma thesis deals with the relationship between machine learning and emotionality. To what extent is artificial intelligence able to undergo emotional relationships and experiences defined by the physicality and experience of the human body. The topic of the work is the creation of a (fictional) inhuman entity that longs to learn from people as many bodily acts as possible that will help it infiltrate the human community. In addition to reflecting the current level of scientific knowledge, I bring an element of fiction and fiction.
9	Odhad pohlaví lebky podle povrchu exokrania s využitím CT skenů / Sex assessment of skull using exocranial meshes from CT scans Musilová, Barbora January 2015 (has links) Sex estimation is a challenging problem in both forensic anthropology and bioarchaeology. Sexual dimorphism is most noticeably displayed by the pelvis; however in instances when it is not preserved, sex is estimated by skull. There is a multitude of approaches that use the skull, however, their population specificity and variable sexual dimorphism oscillation reduces their effectiveness (Bruzek and Murail, 2006). We base our contribution on the study by Abdel Fatah et al. (2014) that estimates sex based on exocranial and endocranial surfaces with a high success rate of 97%. Our approach uses anonymized CT scans of skulls from recent french population, from which the exocranial surface was segmented. On these surfaces, CPD-DCA (Dupej et al., 2014) was performed. We analyzed both form and shape (form after size normalization) of these surfaces in 104 skulls (53 males, 51 females) aged 18 to 92 years. The mean age was 58 years in females and 52.46 years in males. Classification was performed using support vector machines (SVM) with a radial kernel. Leave-one-out crossvalidation was also applied. The highest success rate (87.5 %) was achieved with the first 27 principal components of form. Classification of shape was less accurate by only 2 %. Even though our success rate was lower than that of Abdel...
10	Analýza souvislostí mezi simultánně měřenými EEG a fMRI daty / Analysis of connections between simultaneous EEG and fMRI data Labounek, René January 2012 (has links) Electroencephalography and functional magnetic resonance are two different methods for measuring of neural activity. EEG signals have excellent time resolution, fMRI scans capture records of brain activity in excellent spatial resolution. It is assumed that the joint analysis can take advantage of both methods simultaneously. Statistical Parametric Mapping (SPM8) is freely available software which serves to automatic analysis of fMRI data estimated with general linear model. It is not possible to estimate automatic EEG–fMRI analysis with it. Therefore software EEG Regressor Builder was created during master thesis. It preprocesses EEG signals into EEG regressors which are loaded with program SPM8 where joint EEG–fMRI analysis is estimated in general linear model. EEG regressors consist of vectors of temporal changes in absolute or relative power values of EEG signal in the specified frequency bands from selected electrodes due to periods of fMRI acquisition of individual images. The software is tested on the simultaneous EEG-fMRI data of a visual oddball experiment. EEG regressors are calculated for temporal changes in absolute and relative EEG power values in three frequency bands of interest ( 8-12Hz, 12-20Hz a 20-30Hz) from the occipital electrodes (O1, O2 and Oz). Three types of test analyzes is performed. Data from three individuals is examined in the first. Accuracy of results is evaluated due to the possibilities of setting of calculation method of regressor. Group analysis of data from twenty-two healthy patients is performed in the second. Group EEG regressors analysis is realized in the third through the correlation matrix due to the specified type of power and frequency band outside of the general linear model.
