Topoklima údolí a jeho vliv na vegetaci / The Valley's Topoclimate and Its Influence on the Vegetation

Kuželová, Hana January 2012 (has links)
The Valley's Topoclimate and Its Influence on The Vegetation Abstract The thesis as presented deals with specific valley's topoclimate of a chosen example of one particular valley located near the city Jílové u Prahy. The main objective of the thesis which has been defined is to evaluate the topoclimate of the determined area and its influence on the phytogeographical and phenological situation of the valley. The outdoor temperature measurements carried out by using Assmann's psychrometer as well as the observations of the plant's phenological state have been taken in the course of repeated expeditions into the valley in 2011 and 2012. The formations of night valley's inversions have been confirmed. The temperature gradient of 6 řC and three and half an hour long inversion following the sunrise have been recorded as a result of the measurement performed on 28th April 2012. As a consequence of the valley's parts shading the temperature differences have been proven. As a referential meteorological station the faculty's own station situated on the peak of Pecný hill and the automated personal weather station in Okrouhlo were used. The lower temperatures in the valley have a clear impact on the commencement of the plant's phenological stages. A detailed phenological scale was created in order to observe...

Vítkovice v éře budování státu. Příspěvek k sociálním dějinám / Vítkovice in the Era of State-building. The Contribution to Social History

Dvořák, Jakub January 2015 (has links)
The aim of the diploma thesis called "Vítkovice in the Era of State-Building. The Contribution to Social History" is to describe and analyse social relations and social interactions in Vítkovice in the twenties of the 20th century. It is focused on two main topics which were really important for society in Vítkovice in that period. The thesis consists of two chapters, which are: relation between nations and housing strategy. The dynamics of the society in Vítkovice is determined by the Vítkovice Ironworks. That is reason why company is such important part of the research field. Position of Vítkovice Ironworks was very influential because of connection between the company and the city. Whereas relations between nations were strained because of policy of the company, despite of housing crisis Ironwork's housing strategy helped to unify the society.

Torzo krajiny. Příběh barokní krajiny severních Čech / A torso of a landscape. The story of a baroque landscape of northern Bohemia.

Drápalová, Kristýna January 2016 (has links)
(English) This study has two aims. First, to reconstruct the landscape arrangement of the northern tip of the North Bohemian Basin at the end of the baroque era, focusing on compositional relationships between landscape dominants, both in a scale of pilgrim areas, castles, churches and monasteries and in a scale of chapels and small sculptural and architectonic monuments. The second aim is to, on the example of this - in baroque era extraordinarily rich landscape - examine the phenomenon of the Czech baroque landscape by comparing conclusions of the reconstruction with the widespread conception of compositional principles of baroque landscape. For this purpose, a comprehensive catalogue of architectonic and sculptural monuments in the researched area at about 1780, was compiled. Thereafter a map was created, that shows not only the objects as such, but also the compositional relationships between them. The most important resource for the map was a collection of maps of the First military mapping of Bohemia. In the text, the landscape is described through the perspective of a baroque pilgrim, browsing the landscape along the old roads of three selected routes. The conclusions are then summarized in the final chapter. As a result of my study, I came to the conclusion, that neither the researched...

Výpočtové modelování šíření lidského hlasu vokálním traktem a v prostoru okolo hlavy / Computational modelling of human voice propagation through the vocal tract and in space around the head

Švarc, Martin January 2014 (has links)
The following master thesis deals with creating a computational model for acoustic wave distribution by the human vocal tract and then the space around a human head. Detailed mapping of the sound field around the human head is important for more accurate measurement of the human voice. Part of this work is the creation of three-dimensional finite element model of the human head and the vocal tract during phonation of the vowel /:a/ based on the data from the computational tomography. Further the literature search of the function of the vocal tract, biomechanics of the making of the human voice, an overview of the computational models so far published in the literature and in literature reported measurements of the distribution of the human voice by the vocal tract and then in the space around the head . The following is the actual numerical solution of the acoustic waves distribution from the vocal cords through the vocal tract and then the space around the human head when thinking of acoustic absorption on the walls of the vocal tract and on the skin of the head for different types of waking of the model. The results are compared with previously published measurements of the distribution of the human voice and mainly the distortion of the frequency spectra at each specific node in the space around the head and in its vicinity of where the sensor microphones are typically placed are analyzed. Results of the computational modeling will eventually be used for frequency correction for various positions of the microphones scanning the voice distribution in its diagnosis, speech or singing.

Vztah letokruhových řad k teplotním poměrům na západo-východním gradientu v pohořích střední Evropy / Tree-ring chronologies of Norway-spruce on west-east longitudinal gradient in the mountain ranges of central Europe

Ponocná, Tereza January 2017 (has links)
The Earth's climate system has recently experienced substantial warming which likely impacts temperature-limited communities close to their distribution margins. The alpine treeline ecotone represents upper distributional limit of montane/subalpine forests. This biogeographic boundary relies mainly on decreasing temperature with increasing elevation. Surprisingly the response of treeline ecotone to ongoing warming has varied a lot and the reasons of this variability are poorly understood. The aim of this dissertation thesis is the assessment of growth trends and tree ring response of Norway spruce (Picea abies[L.] Karst.) to climatic oscillations at treelines and montane forests of East-Central Europe. This dissertation deals with both inter-regional and intra-regional (aspect, elevation) variability of tree growth. The presented results are based on an extensive data set of growth curves for almost 1400 trees. All study sites revealed close relationship between tree ring widths and growing season temperatures as well as the temperatures of October preceding to ring formation season. The main site-dependent differences in growth trends and temperature responses were attributed to elevation, the effect of aspect was relatively less significant. At treelines between the Krkonoše Mts. and Nízké Tatry...
