Hnízdní preference jiřičky obecné (Delichon urbica) v urbánní krajině

Dvořáková, Denisa January 2019 (has links)
The thesis evaluates the birdlife preferences of the common house martin in the territory of the Czech Republic. The survey of the literature focuses on obtaining information from available sources that relate to nesting preferences according to different criteria, such as environmental habitat conditions, influence of the human factor, and others. In the practical part of the thesis 12094 records have been collected concerning the nesting of the common house martin in the Czech Republic in the period from 2009 to 2017, drawn from the faunistic database of the Czech Society for Ornithology. The data was correlated with the data on the conditions found in the separate habitats and analysed by the statistical methods Boosted regression trees (BRT) and Generalized Least Squares (GLS). The obtained results show that owing to the insect life the common house martin most prefers the areas with field and wetland ecosystems, and rather also the suburban lowland region. A major negative influence on the common house martin appeared to be mining areas in industrial estate.

Vliv úprav toků a nivy na následky povodní na příkladu povodí Volyňky / Impact of stream and floodplain modification on the flood effects.

Rettichová, Zuzana January 2010 (has links)
The thesis deals with evaluation of the Volyňka river network modification on the basis of field survey, and identification of critical stream segments, which may influence course of flood events by means of GIS analysis. Two extreme floods took place in the Volyňka river basin in the years 2002 and 2009. The paper evaluates causes, course of events and effects of the floods. To get information about river network modification the HEM-F fiels survey methodology was used. The whole stream of Volyňka river was investigated from its spring to Volyně town, the tributaries in the upper part of the Volyňka river basin and the stream Spůlka. Intensity of stream modificatin and flood effects character were evaluated and critical sections were indentified on the basis of the mapping results. The potential flow obstacles are the most frequent type of critical modification of the stream. Especially the unsufficiently designed bridges, weirs and culverts cause the most intensive damage and geomophological effects of the flood. Individual kinds of obstacles are typical for certain sections of the river flow. Modifications limitating use of retention potential of the floodplain are often present in the central and lower parts of the Volyňka river basin. In several critical stream segments there were proposed...

Mapování heterogenity půdních podmínek v precizním zemědělství

Oudová, Barbora January 2017 (has links)
Precision agriculture is an agronomic approach that aims to optimize inputs into agricultural production to achieve balanced, qualitatively and quantitatively the best possible yields, while minimizing the financial costs and maintain or improve the environment. The basic premise of this approach is the knowledge of soil conditions of land used for agricultural production. This information can be found in agronomic records, soil maps or results of agrochemical testing. Indirect methods of soil heterogeneity mapping based on the principle of sensor measurements and remote sensing are also available. Indirect methods for determining the physical-chemical properties of soil are generally user-friendly, cheaper, faster, and have a higher density of measurement points than the sampling of soils. Comparison of direct and indirect methods showed that indirect methods provide a detailed picture of soil variability. However, interpretation of results is affected by many other factors, which are based in the principle of soil het-erogeneity itself.

Pasportizace staveb zemědělských podniků pomocí bezpilotní technologie a porovnání s KN / Inventory of farm buildings using unmanned aerial vehicle and comparison

BOŽÁK, Pavel January 2018 (has links)
This dissertation deals with unmaned aerial vehicles and their use in an accurate photogrammetric mapping. The very first part of my thesis describes a history of UAV (unmaned aerial vehicles) and a theoretical introduction of the issue. In the second part of this thesis a specific example of mapping agricultural area with a missing building in cadastral map is solved. The disertation is focused on an aerial photo-shooting and then on matching the pictures in the software Agisoft Photo Scan. The result of the work is a detailed ortophoto map of the agricultural area where the missing building is exactly positionally determined.

Konceptualizace emocí v českém znakovém jazyce (Na příkladu hněvu) / Conceptualization of emotions in the Czech Sign Language (On the example of anger)

Gardelková, Barbora January 2017 (has links)
This thesis is focused on the conceptualisation of emotions in Czech Sign Language with the emphasis on the linguistic conceptualisation of anger. At the beginning the author reveals basic theoretical issues of the cognitive linguistics of spoken and sign linguistics. Afterwards she presents some general facts about metaphor and metonymy in spoken and sign languages - with the main focus on the metaphorical-metonymic conceptualisation of anger - and shows metaphors and metonymies of anger in the English, Polish and Czech language. The core of the thesis consists of the linguistic research of anger in Czech Sign Language. The author identifies basic metaphors and metonymies of the concept of ANGER in Czech Sign Language within the empirically gained linguistic material. The gained data from all four languages are compared and presented in a table at the end of this paper. Key words: cognitive linguistics, emotions, conceptualisation of emotions, the concept of ANGER, Czech Sign Language, metaphor, metonymy, metaphorical mapping, iconic mapping, iconic-metaphorical mapping.

Pattern-based Ontology Matching and Ontology Alignment Evaluation / Mapování ontologií a jeho vyhodnocování pomocí vzorů

Zamazal, Ondřej January 2006 (has links)
Ontology Matching is one of the hottest topic within the Semantic Web of recent years. There is still ample of space for improvement in terms of performance. Furthermore, current ontology matchers mostly concentrate on simple entity to entity matching. However, matching of whole structures could bring some additional complex relationships. These structures of ontologies can be captured as ontology patterns. The main theme of this thesis is an examination of pattern-based ontology matching enhanced with ontology transformation and pattern-based ontology alignment evaluation. The former is examined due to its potential benefits regarding complex matching and matching as such. The latter is examined because complex hypotheses could be beneficial feedback as complement to traditional evaluation methods. These two tasks are related to four different topics: ontology patterns, ontology transformation, ontology alignment evaluation and ontology matching. With regard to those four topics, this work covers the following aspects: * Examination of different aspects of ontology patterns. Particularly, description of relevant ontology patterns for ontology transformation and for ontology matching (such as naming, matching and transformation patterns). * Description of a pattern-based method for ontology transformation. * Introduction of new methods for an alignment evaluation; including using patterns as a complex structures for more detailed analysis. * Experiments and demonstrations of new concepts introduced in this thesis. The thesis first introduces naming pattern and matching pattern classification on which ontology transformation framework is based. Naming patterns are useful for detection of ontology patterns and for generation of new names for entities. Matching patterns are basis for transformation patterns in terms of sharing some building blocks. In comparison with matching patterns, transformation patterns have transformation links that represent way how parts of ontology patterns are transformed. Besides several evaluations and implementations, the thesis provides a demonstration of getting complex matching due to ontology transformation process. Ontology transformation framework has been implemented in Java environment where all generic patterns are represented as corresponding Java objects. Three main implemented services are made generally available as RESTful services: ontology pattern detection, transformation instruction generation and ontology transformation.
