ICT in work of principal of primary school
Kubínová, Lucie ; Hubert, Vlastimil (advisor) ; Kursch, Martin (referee)
This bachelor thesis deals with deficiencies that elementary school principals must solve in the field of ICT. In particular, there is a lack of the resources available, especially hard sources including ICT equipment, a lack of space for ICT equipment and inadequate connectivity on the Internet, but also soft resources in the field of human resources are missing. This thesis has two goals. The first goal is to find out what kind of deficiencies it is and how big they are and the second goal is to make recommendations for elementary school principals how to deal with these deficiencies. The research that is part of this thesis was focused on principals of elementary schools in the South Moravian Region. The research is conceived as a quantitative survey using an online Internet questionnaire. From the 66 expected respondents to 16 research questions, an analysis is found that leads to the conclusion that my four hypotheses were right. The questions are mainly focused on the finding the type of the shortage and its size from the point of view of elementary school principals, while there is 1 sorting question ( concerning school size) and the last question is focused on the type of education / training of elementary school principals in ICT. Based on the existing deficiencies the recommendation is...

We focused on methods that exploited advantages of confocal and multi-photon excitation microscopy. Our further aim was to demonstrate the applicability of non-invasive approach for in vivo applications, usefulness and the relevance of these methods in several special biological applications with emphasis on improved image acquisition, analysis and evaluation of real biological specimens. The present work was not oriented on just one specific biological problem, but rather to methodological...

The thesis familiarises with characteristic of whole process and particular duties of liquidator. In the second part the thesis is focusing on statistical mapping of the situation in the field of business companies liquidation in Czech republic.
Doprovodná vegetace komunikací
Kubínová, Lucie
This work Accompanying vegetation of road deals with the issue of development and advencement of roads and their vegetation accompaniment, comprehension the relation between the landscape and the road, the function of this vegetation and issue of the space arrangement and specific composition. Vegetations along routes assist in integration the road to the landscape, improve and stabilize the conditions in the surrounding area, influence the human perception, improve the estetic appearance and provide the economic profit. On the basis of the evaluation the available information was finded out, that the optimum solution is accept social, historical, cultural and especially biological and landscape specifications. Roads should be planted by appropriate variety of the vegetation of the reliance on the type of road and the optimum function of the vegetation. This way will be provide, that the road and the landscape will create the well-balanced komplex in both aspect -- functional and esthetic.
Elastic registration of biomedical images on CUDA-Supported graphics procesor units
Michálek, Jan ; Čapek, Martin ; Janáček, Jiří ; Kubínová, Lucie
Elastic registration is a task of finding the matching of two images, using geometric and elastic transformations, so that objects in images have the same size, position and orientation. We apply elastic registration in the framework of volume reconstruction, where an object acquired from parallel physical sections is composed and mutual positions of the sections including deformations caused by their cutting have to be found. The method lies in optimizing a functional consisting of two parts: first, discrete total variation as a measure of roughness and, second, L1 norm as a measure of dissimilarity of images. As a parallelizable optimization strategy we apply a potential-based equivalent transformation of a (max,+)-labelling problem. CUDA-based implementation of the described elastic registration algorithm is reasonably fast, requires seconds to minutes of calculations, provides good results and, thus, can be used for practical tasks dealing with alignment of biomedical images
Application of morphology filters to compensation of lateral illumination inhomogeneities in confocal microscopy images
Michálek, Jan ; Čapek, Martin ; Mao, X. W. ; Kubínová, Lucie
Due to multiple distortion effects, confocal laser scanning microscopy (CLSM) images of even homogeneous specimen regions suffer from irregular brightness variations. In this paper, a fast correction method based on estimating a spatially variable illumination gain, and multiplying acquired CLSM images by the inverse of the estimated gain, is presented. The method does not require any special calibration (reference) images since the gain estimate is extracted from the CLSM image being corrected itself. The proposed approach exploits two types of morphological filters: the median filter and a morphological operator called the upper Lipschitz cover
Multi-fotonová exitační mikroskopie
Chernyavskiy, Oleksandr ; Kubínová, Lucie
Multiphoton excitation microscopy (MPM), being some time ago rather exotic than an easy-to-handle tool, becomes now more widely used due to advances in laser technique. This promising, yet expensive technique provides such advantages, as deeper penetration depth, lower photodamage, especially important in live cells imaging for extended periods of time
Ohodnocení chyby objemové rekonstrukce biologických vzorků z konfokálních obrazů
Čapek, Martin ; Janáček, Jiří ; Kubínová, Lucie ; Smrčka, P. ; Hána, K.
We performed both volume reconstructions using images captured by the USB microscope and images captured by the confocal microscope. We manually marked important corresponding structures in both reconstructed data sets, and computed distances between corresponding structures, assuming that structures in the reconstruction from USB microscope data are without deformations. According to our expectations, the main errors of high-resolution volume reconstruction (from confocal data) are in the direction of physical cutting (vary in units of millimeters) and in the direction perpendicular to cutting due to off-cut (vary in tenths of millimeters)
Přístupy k visualizaci obrazů 3D struktur získaných konfokálním mikroskopem
Čapek, Martin ; Janáček, Jiří ; Kubínová, Lucie ; Hána, K. ; Smrčka, P.
Laser scanning confocal microscopes are capable to focus a laser beam into a layer of an investigated biological specimen, and by the gradual scanning of this layer they acquire an optical section. By consecutive scanning of all preset layers of the specimen we obtain a stack of optical sections, i.e. a 3D digital representation of the specimen. In the presented study we focus on volume reconstruction of large biological tissues, i.e. tissues greater than field of view and/or thicker than maximal depth of scanning of a confocal microscope. As a result of volume reconstruction we obtain a high resolution 3D image of the biological specimen. 3D visualization is offered either by our Rapid3D software package suited for three-dimensional reconstruction and visualization of biomedical images, or Ellipse modular software package devoted to biological image processing (created by ViDiTo company, Slovakia)
