Information asymmetry in economics
Kolar, Jan
The subject of the article is the concept of information asymmetry, which currently belongs among highly discussed themes in economics. In the article, we deal with the basic concepts, which play an important role in the overall perspective on the given issue. One of them is moral hazard, which is a fundamental consequence of information asymmetry. The market subjects or individual people often misuse their superior informational capabilities for their own use, but at the same time they inadvertently contribute to the inefficiency of the specific market, which can lead to extensive market failure. Other important consequences include so-called adverse selection, which results in the gradual displacement of good products by inferior ones. The occurrence of adverse selection in the specific market then results in pressure to reduce prices. In particular, the article analyses the current state of knowledge in the area of information economics, on the basis of previously published articles. We also deal with the effect of modern technology on the economic mechanism and information asymmetry. One of them is the internet, which plays a key role in the transmission of information. The aim of the article is to perform an analysis of the current state of knowledge in the area of information asymmetry on the basis of relevant published articles, and thus create a comprehensive and compact perspective on the given issue. An important section is the analysis of the possible impact of modern technology on information asymmetry, where own conclusions are drawn on the basis of findings by various authors.

Determination of snow water equivalent from microwave radiometer measurements
Klímová, Tereza ; Kolář, Jan (advisor) ; Potůčková, Markéta (referee)
DETERMINATION OF SNOW WATER EQUIVALENT FROM MICROWAVE RADIOMETER MEASUREMENTS Abstract Snow water equivalent ammount of water in snow and its knowledge helps for example in flood prognostication. This bachelor thesis engages with determination of snow water equivalent from microwave radiometer's data in cooperation with data from ground stations. Norway was choosen because of its good data availability. Microwave radiometer AMSR2 on Japanese satellite GCOM has been used as a basic instrument. For map creation with snow water equivalent method considering differences of two spectral canals and other snow attributes were used. During verification of this method maps from Norwegian Meteorological Institute and EUMETSAT which provils different method in map creation were used. keywords: snow water equivalent, remote sensing, microwave radiometer

Heterogeneity in forest vegetation monitoring with remote sensing
Kolešová, Petra ; Kolář, Jan (advisor) ; Potůčková, Markéta (referee)
Heterogeneity in forest vegetation monitoring with remote sensing Abtract The main aim of this diploma thesis is to examine the suitability of various classification approaches for forest vegetation categorization using Landsat 8 satellite imagery. Two satellite images acquired during vegetative period (8th March, 27th July 2013) were chosen. The overall goal of the study is to explore the potential of using statistical methods to obtain information about forest heterogeneity in a given territory. Chosen study sites are defined by administrative boundaries of selected municipalities from South and Central Bohemia located within following municipalities with extended powers - Blatná, Milevsko, Písek, Příbram and Sedlčany. Supervised and unsupervised classifications were used based on obtained training areas and orthophoto. The definition of chosen classes (coniferous forests, mixed forests, ecotones, structurally homogeneous deciduous forests and structurally heterogeneous deciduous forests) was identical with the categories used in "Project MT 11425-5/2010 The Mapping of Natural Zoonoses Focal Points, Transferable on Humans in the Czech Republic and Their Changes Affected by the Modification of Climate". Due to large amount of training datasets obtained from field survey, ortophoto and spectral analysis,...

Drug Issues in Czechoslovakia 1918 - 1960
Šinkovec, Pavel ; Randák, Jan (advisor) ; Kolář, Jan (referee)
(in English): This thesis describes the development of the Czechoslovak drug issue between years 1918 and 1960. This period is divided into three parts, which contains an image of the drug scene, drug users, public view on the issue, the reaction of officials on the problem and connection with foreign scenes. The first part deals with the First Czechoslovak republic and its drug abuse within the upper class and demimonde. The second part describes the nearly disappeared drug issue in the 1940's. Lastly the third part deals with the drug scene in the 1950's, that was officially gone, while it just took the form of latent abuse of medicaments. The main focus is on changes of the drug scene and their causes.

Maps creation from image data of the Mars surface
Kopecký, Kamil ; Kolář, Jan (advisor) ; Čábelka, Miroslav (referee)
Spectral behavior of Mars altimetry Abstract The goals of this thesis are research of cartography of Mars and the problems connected with it. The second goal is the creation of the maps of Mars's surface and lastly the analysis of the surface elevation and its spectral behavior. Firstly, the thesis outlines the theoretical part which includes usage of reference bodies, coordinates systems, cartographic projections and prime meridian. Second, it features the methodical procedure of creating the maps and the analysis. Key words: map projection, image data, Mars surface, thematic maps

International sales contract
Kolář, Jan ; Pauknerová, Monika (advisor) ; Pfeiffer, Magdalena (referee)
Jan Kolář - International sales contract Abstract Topic of this master's thesis is international sales contract, more specifically remedies for the breach of international sales contract. As a substantive law by which remedies for the breach of international sales contract are judged is the United Nations Convention on Contracts for the International Sale of Goods. Reason for choosing the United Nations Convention on Contracts for the International Sale of Goods as a substantive law for this thesis is that this convention represents one of the most successful and most widely used international legal norm used to govern international trade in today's world. This is mainly because of the Convention's well balanced and impartial approach and also the fact that the Convention has been ratified in 83 states which significantly contribute to the overall volume of an international trade. This thesis mostly uses analytical and descriptive legal research methods. This is given by the nature of its subject. However, the thesis does not only describe provisions of the Convention but aspires to point its reader to most salient and problematic features of the Convention. The thesis is divided into six chapter, introduction and conclusion. For better clarity chapters are further structured into two more levels. First...

Using SAR data for wet snow monitoring
Matyáš, Jiří ; Kolář, Jan (advisor) ; Součková, Jana (referee)
Using SAR data for wet snow monitoring Abstract This paper focuses on an existing method of snow information retrieval by means of satellite SAR data. The method was first presented by Malnes and Guneriussen (2002), and has been proven to be capable of sub-pixel classification of wet snow. It is also able to classify dry snow pixels. The classification is based on change detection, so a snow-free reference image is required. Some flaws in this algorithm have been discovered during the work on this paper and are discussed, as well as a possible solution is suggested. I have also proposed a modification of the algorithm which could improve the classification results and tested the modified algorithm. Keywords: SAR, snow cover, remote sensing, wet snow

Modeling of solar irradiance for lunar base locations
Čašek, Jakub ; Brůha, Lukáš (advisor) ; Kolář, Jan (referee)
Modeling of solar irradiance for lunar base locations Abstract An incident radiation is an essential factor for a discovery of a place suitable for building a lunar base. This thesis presents a new approach for modeling of solar irradiance in an arbitrary lunar location at selected time. Shadowing by surrounding terrain is calculated by spatial intersection between lines of illumination and digital terrain model. Model also takes variable distance between Moon and Sun and areal representation of the Sun into account. In this thesis a new geometrical procedure for calculation of reflected irradiance is designed. The resulting model is implemented within ArcGIS software as an executable script, which utilizes the freely available data from Lunar Reconnaissance Orbiter as an input. Key words: Moon, solar irradiance, geoinformatic modelling, scripting
