Analyses of remote sensing techniques for detecting quartz and calcite in rock
Šourková, Lucie ; Štefanová, Eva (advisor) ; Pavelka, Karel (referee)
Remote sensing technique in geology is relatively fast and low cost procedure for initial research method preceding a more detailed field campaign. Remote sensing offer an excellent method of mapping surface geology mainly in arid regions. The analysis of remote sensing methods for silicon and calcium detection is the aims this thesis. The method were tested on satellite sensors Aster and Landsat ETM+ in Sechura desert region in northwest of Peru. For solution to mineral detection was the Aster data the most suitable. The data was preprocessed. From the atmospheric correction method was chosen the Empirical Line Calibration. The best methods for good identification of silicate and calcite were: mineralogic combination 5/7-5/4- 3/1 ETM+ bands, color composite ratio bands Aster 13/10-13/14-12/13, Principal Component Analyses and classification Spectral Angle Mapper. On the strength of results was suggested metodical procedure including steps from preprocessing to classification. Powered by TCPDF (www.tcpdf.org)

Search Engine Optimization
Havíř, Vojtěch ; Karlíček, Miroslav (advisor) ; Holeček, Jan (referee)
The subject of this bachelor thesis is search engine optimization for web pages. In the theoretical part of this thesis you can find a brief information summary about search engines on the Czech Internet. It is followed by a list of methods that can be used as part of an optimization for improving search engine ratings and also methods which can help only in the short term and are in case of detection penalized by the search engines. In the next part of the thesis is an overview of useful instruments that provide us with a variety of information about the level of web page optimization and other information that can be useful throughout the process of optimization. On the practical side, the thesis focuses on a level of search engine optimization of a student webpage unium.cz and some of the key changes that the owners have done are mentioned and their impact on a total number of visitors is evaluated. In the end you can find some recommended adjustments that could help to better ranking among the search engines.

Biological activity of plant metabolites. VI. Influence of alkaloids from several taxons of plants on acetylcholinesterase
Řepová, Lucie ; Opletal, Lubomír (advisor) ; Karlíčková, Jana (referee)
Řepová, L.: Biological activity of plant metabolites VI. Influence of alkaloids from several taxons of plants on acetylcholinesterase. Diploma thesis, Charles University in Prague, Faculty of Pharmacy in Hradec Králové, 2007. In content of the diploma thesis it was realized screening of the alkaloids of some taxons of tribes Papaveraceae and Fumariaceae on acetylcholinesterase inhibition. It was introduced a method for obtaining optimum extracts (alkaloidal concentrates of certain type) from various morphological parts of plants Corydalis cava (L.) Schweigg. et Koerte (root), Uncaria tomentosa (WILLD.) DC. (bark), Tabebuia impetiginosa (Mart. ex DC.) Stangl. (bark), Peumus boldus (Molina) (leaf) a Papaver somniferum L. (poppy head). After the preparation of primary extract, its acidification and preliminary cleaning, extracts of different basicity were prepared by extraction either by diethyl ether (L, pH ∼2; A, pH ∼8; B, pH ∼12) or by chloroform (A1, pH~8; J, pH ∼3; E, pH ∼10). Single types of extracts were eluted by means of TLC metod both in neutral and in alkaline system of solvents on the silica gel and were tested on contents of alkaloids (detected by Dragendorff agent). Extracts contaning alkaloids were further checked together with standards (physostigmine and galanthamine) by aid of...

The causes of school immaturity
Zemanová, Markéta ; Linková, Marie (referee) ; Kropáčková, Jana (advisor)
The thesis deals with the most frequent causes of school immaturity and their aspects. The theoretical part characterises and defines concepts linked with school maturity as the auditory and visual perception, kinetics, communication and mathematical imagination and the adherent problematics of the preschool period. It also focuses on the legislation pertaining the admission of the child to grammar school. The practical part analysis individual methods detecting the school immaturity. On the basis of analysing the childern work and summarisation of its results it is verifying the objectivity of the created test and also investigates the most frequent causes of school immaturity. On the basis of observation and dialogues it traces the social immaturity. The conclusion summarises findings from the individual methods and partial conclusions of the chapters.

Solving of blending and diet problems
Křenková, Michaela ; Fábry, Jan (advisor) ; Čížek, Ondřej (referee)
The aim of this work is to ascertain in which situations can be used models of blending and diet problems. It will draw together different examples and describing steps in solving them. The work is divided into two main Chapters: - Blending Problems, and Diet Problems. Both types of linear programming problems are first briefly discussed, which is then followed by the creation of a mathematical model, with explanations for creating constrains and objective functions. Examples are solved with optimizing software LINGO.

Heat recovery in Building Services
Hrabová, Kristýna ; Plášek, Josef (referee) ; Šikula, Ondřej (advisor)
This thesis deals with the optimization of sewer heat recovery. For proper design and optimization it is necessary to use three basic methods: diagnostics, heat balance calculations and modeling. In 2D software Area Calculation are simulated different types of sewer exchangers arranged in sewer pipes. Using models of software CalA and simulations will be selected optimal variant. Using software BSim, which is based on more zone numerical simulation of the energy needs of buildings in relation to indoor climate, are detected heat needs of an office building. The optimal number of sewer exchanger is designed from the identified performance heat exchangers and supplies heat for the building.

Study of the impact of the new energy block Domoradice on local climate II
Sokol, Zbyněk ; Řezáčová, Daniela
The study stems from a previous work, where we used a mathematical model CT-PLUME / DOM. It is a basic model CT-PLUME adapted to assess the effect of mechanical cooling towers located in Domoradice on the model area. This study differs from the previous one in two respects: it processes 3-year period (2013, 2014 and 2015) and in addition to the basic climatic characteristics pays attention to icing. For this study, the basic module used before should be extended to model the conditions for the formation of ice in the vicinity. The final version of the model used in this study is referred to as CT-PLUME / DOM-2.

Uncertainty associated with survey design in species distribution models
Vrabeľ, Matej ; Moudrý, Vítězslav (advisor) ; Barták, Vojtěch (referee)
Properly choosen input data, their form, way of the collection an the following correction as well, are the key factors affecting the accuracy of the more and more popular models of the species model distribution (SDM). A design unfluence of the data to the choosen distribution model of the virtual species has been tested. The General Linear Model (GLM) has been used. Four types of the present-absent collection designs have been tested for a virtual species on the area of the Czech Republic as follows: accidental, systematic, points on the easy accessible areas (near the communications) and the points with the higher concentration of the scientists (an area of CHKO).The TSS (True skills statistics), KAPPA and AUC (Area under curve) have been used to compare the accuracy of the prediction of the models .The points being choosen from the easy to access areas and CHKO had worse results in all of the monitored values than the accidental or the systematic choice of the points from the whole area of the Czech Republic.It results that the data collection mode affects the final accuracy of the species distribution models.
