Localization of IP stations based on model of probability delay measurement
Tropp, Peter ; Komosný, Dan (referee) ; Verner, Lukáš (advisor)
The master thesis is dealing with Internet host localization methods, more exactly with determining geographical position of the unknown Internet host connected to the network using RTT delay measuring. The first part is dealing with description of RTT delays that may occur in the network and tools for their measurement. The next is part of thesis is devoted to description of two kinds of localization methods. Ones that are using existing data to determine the position of Internet host also called passive methods, and others that are using RTT delay measurement, also called active methods. The main part is focused on GeoWeight method which is based on geographical localization estimation of Internet host. It is based on RTT delay measurement using the principles of CBG method, enhanced by introduction of the theory of weights according to the probability of the target Internet host. The last part is describing the application that was made to determine the geographic localization of the target Internet host using GeoWeight method. The application was afterwards tested by measuring RTT delay in PlanetLab experimental network. At the end the final measured results were compared with other localization methods (CBG, Octant, SOI, GeoIP).

Explainable Convolutional Neural Networks
Kamenický, Daniel ; Herout, Adam (referee) ; Hradiš, Michal (advisor)
The aim of this work was to compare several methods for visualizing the features of each class on the input pixel layer of the CNN. Each method uses a different algorithm, based on gradients, to compute the resulting values. Using the implementation of each method, the resultant values of the methods are obtained by using the equation of energy concentration. The resultant values are presented in tables and graphs from which the success rate of the result of the work can be read. The difference between the methods and comparison of their results can be read from the work. This makes it possible to get an overview of gradient based visualization methods.

Multiple-criteria Decision Making and Data Envelopment Analysis
BRABCOVÁ, Michaela
This thesis explores methods of multiple-criteria decision making in connection with data envelopment analysis. A model task is to compare all the countries of the European Union according to the growth of their small and medium-sized enterprises. The differences and similarities of the chosen approaches are shown on the selected data. The results include the ranking of countries based on efficiency according to the CCR model and a comparison of the results from data envelopment analysis and the described multi-criteria methods using Spearman coefficients. As the results of the multi-criteria evaluation of alternatives depend strongly on the weights, their stability for the weighted sum approach and PROMETHEE was therefore examined.

Multicriteria analysis of current accounts on the Czech banking market
Pacovská, Lucie ; Jablonský, Josef (advisor) ; Kuncová, Martina (referee)
This diploma thesis deals with the analysis of current accounts on the Czech banking market. Its goal is to find the most appropriate accounts for different types of clients. The work is divided into three parts. The theoretical part describes the problem of multicriteria decision making, basic concepts and principles, methods for calculating weight of the criteria and individual methods of multicriterial evaluation of alternatives. The second part is devoted to the description of the currently offered current accounts for individuals and a description of the selected criteria according to which the individual alternatives are evaluated. The last computational part tries to find the most appropriate accounts for those clients. Weights are calculated using the scoring method and DEMATEL method. Subsequently, the best accounts are selected by WSA, TOPSIS, ELECTRE III and MAPPAC. The calculations are made by using MS Excel add-in application Sanna.

The beginnings of textile production in the Czech Republic. Selected questions of textile production practised on the territory of the Czech Republic at the end of the Stone Age.
Korteová, Judita ; Dobeš, Miroslav (advisor) ; Březinová, Helena (referee)
This work assesses the evolution of textile production in the Czech lands during the Eneolithic, a period that is the earliest source of broader archaeological information for the study of textile manufacturing. The basis for the study is provided above all by archaeological finds of textile tools (spindle whorls, weights, spools and awls) that are evaluated within individual archaeological cultures in terms of quantity, shape, size and function, archaeological context and chronological development. This is supplemented by a survey of fragmentary textiles and their imprints dating from the Stone Age in the Czech Republic. Another important source of information is provided by findings from research into Eneolithic pile-dwelling settlements around Alpine lakes that have provided numerous finds of archaeological textiles as well as textile-making tools and tool fragments that have not been found in the Czech lands. An interesting comparative set of artefacts is provided by the objects found in the possession of the mummy of Ötzi dating from the Middle Eneolithic Period. The second part of the work focuses on the experimental testing of several hypotheses formulated on the basis of the study of archaeological materials. The experiments focused on the potential of working bast fibre from trees as an...
