Approximate Shortest Distances Among Smooth Obstacles in 3D
No full textWe consider the classic all-pairs-shortest-paths (APSP) problem in a three-dimensional environment where paths have to avoid a set of smooth obstacles whose surfaces are represented by discrete point sets with n sample points in total. We show that if the point sets represent epsilon-samples of the underlying surfaces, (1 ± O(sqrt{epsilon}))-approximations of the distances between all pairs of sample points can be computed in O(n^{5/2} log^2 n) time

Calibrated XRF-scanning data (mm resolution) and calibration data (ICP-OES and ICP-MS) for elements Al, Ba, Mo, Ti, and U in Mediterranean cores MS21, MS66, and 64PE406E1
No full textSediment cores were collected using a piston corer at three sites in the eastern Mediterranean Sea. Piston cores MS21 (32°20.7'N, 31°39.0'E; 1022 m water depth; 751.5 cm in length) and MS66 (33°1.9'N, 31°47.9'E; 1630 m water depth; 630 cm in length) were recovered during the MIMES cruise with the R/V Pelagia in 2004. Piston core 64PE406E1 (33°18.1'N, 33°23.7'E; 1760 m water depth; 920.5 cm in length) was recovered during the Eastern Mediterranean part of the 64PE406 (NESSC) cruise with the R/V Pelagia in 2016. The cores were opened and then prepared for X-Ray Fluorescence (XRF) core scanning by carefully flattening the sediment and covering it with a 4-μm SPEXCerti Ultralene foil. Subsequently, the sediments were XRF-scanned with a 1-mm resolution using four settings (10 kV-no filter, 20 kV-Al filter, 30 kV-Pd-thick filter, and 50 kV-Cu filter). The produced XRF-core-scanner data were calibrated using a subset of the discrete samples taken from the same core material. These samples were digested with an acid mixture and partially measured by inductively coupled plasma mass spectrometry (ICP-MS) and partially measured by ICP-optical emission spectroscopy (ICP-OES). The main purpose of our data collection was to reconstruct in detail (~10-50 yr resolution) the deoxygenation and anoxia in the eastern Mediterranean Sea during the last 300 ka BP; we focused on elements and elemental ratios of Al, Ba, Mo, Ti, and U

Efekty urbanizace a atmosférické chemie v modelování klimatu
No full textTitle: The effects of urbanization and atmospheric chemistry in climate modelling Author: Jan Karlický Department: Department of Atmospheric Physics Supervisor: doc. RNDr. Tomáš Halenka, CSc., Department of Atmospheric Physics Abstract: This work is dealing with the modelling of the climate on the regional scale with an emphasis on the impact of urban areas on the local climate or simply urban climate. The importance of the impact of urban surfaces on the local climate and living conditions is discussed in detail in theoretical sections, followed by the model study showing all consequences of the urban climate. The results showed that all models and urban parameterization used are able to reproduce the summer evening and nocturnal urban heat island with the magnitude of 2- 3 o C. The impact of cities on other meteorological variables depends more on the urban parameterization used. The urban induced changes have mostly a positive effect on the weather conditions with regards to the pollutant dispersion. Further, the thesis also deals with the modelling of atmospheric chemistry on the regional scale. Modelled ozone concentrations match the observation quit well, while the simulated concentrations of other gases are highly underestimated.

RNDr. Tomáš Halenka, CSc., Katedra fyziky atmosféry Abstrakt: Tato práce se zabývá modelováním klimatu na regionálním měřítku s důrazem na vliv městských oblastí na místní klima či souhrnně klima města. Výz- nam vlivu městských povrchů na místní klima a životní podmínky je podrobně probrán v teoretických částech práce, následující modelová studie popisuje další specifika spojená s klimatem města. Její výsledky ukazují, že všechny užité mod- ely a parametrizace města jsou schopny zachytit letní večerní a noční městský tepelný ostrov o intenzitě 2-3 o C. Vliv měst na další meteorologické prvky se podstatně liší v závislosti na použité parametrizaci městského prostředí. Měst- ské povrchy mají převážně pozitivní vliv na rozptylové podmínky. Práce se také zabývá modelováním atmosférické chemie na regionální úrovni, výsledné mode- lové koncentrace ozonu se dobře shodují s měřeními, avšak modelové koncentrace dalších hodnocených plynů jsou výrazně podceněny.

Jan Kapr's contribution to contemporary music : an essay about a composer and teacher
No full textThis creative project is a treatise on a leading personality of Czechoslovakian musical life, the composer, Jan Kapr. The author discusses the following:1. The complicated development of Kapr's career and work, 2. Kapr's method of organization of musical material in a composition, as described in his book Constants,3. His former and current style which is demonstrated in two of his compositions, Concert Variations, for flute and string orchestra and Testimonies for four solo instruments,4. Two of his recent works, Exercises for Gydli and the Symphony No. 7, Country of Childhood.Thesis (M.A.
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
ELEVEN FACES OF JAN GOGOL, JR.
No full textAuthor Jan Rendl in his thesis attempts to look at the world of ideas and educator Jan
Gogola ml. through the eleven chapters in which each chapter somehow characterizes itself by Jan Gogola ml. and each of them somehow determines its creative ideas of it through the metaphor of a football match when Jan Gogola, with its characters, movies himself a teammate, as well as defensively. It gives goals with their situations as well as occasionally digging his opponents ankles.
Jan Gogola ml. thus embodies one stage of the Department of Documentary Film at FAMU, which often stands at the intersection between teaching activities and Karel Vachek among students who applied by them during their seminars psychological methods that work must be peculiarly associated with the author of the film
