Analysis of DDos data with clustering
Krátký, Matěj ; Šišmiš, Lukáš (referee) ; Setinský, Jiří (advisor)
This thesis focuses on the detection of distributed denial of service (DDoS) attacks using clustering algorithms. In the first part, different types of DDoS attacks and approaches to identify them are described. Next, the thesis studies clustering methods, specifically hierarchical and k-means clustering, for analyzing the network traffic associated with these attacks. It also includes the design of a detection system suitable for detecting DDoS attacks. This is followed by a description of the implementation of this system required for the analysis phase. The main part of the work consists of performing experiments on the available dataset and evaluating the effectiveness of the methods, parameters and attributes combinations used. Finally, the thesis discusses the application of the findings and the possibilities for further research in this area.

Mapping survey of the SOS children's village in Brno-Medlánky
Vítek, František ; Nosek, Jakub (referee) ; Kuruc, Michal (advisor)
The bachelor thesis deals with the update of the thematic map of the SOS village area in Brno-Medlánky and its subsequent conversion into a geographic information system environment. The thesis describes the entire process of updating the thematic map from reconnaissance and field data collection to computational and graphic processing. Furthermore, it outlines the conversion of the map into the QGIS software. The main outputs of the thesis are the purpose map at a scale of 1:500, and a project in QGIS containing map elements converted into a shapefile format.

Attribute based authentication
Chwastková, Šárka ; Hajný, Jan (referee) ; Dzurenda, Petr (advisor)
This thesis deals with attribute based credentials. It describes attribute systems, their entities and properties generally. The work concentrates specifically on the attribute system Identity Mixer. The process of communication of the attribute system Identity Mixer is implemented in the language of JavaScript. Application is the web visualization, which describes protocols, entities and generally computes protocols of Identity Mixer with inputs of small numbers or predefined large numbers.

Automatic Image Labelling
Lukáč, Michal ; Řezníček, Ivo (referee) ; Hradiš, Michal (advisor)
This thesis focuses on automatic image labelling to semantic categories. It describes the theory of classif cation and local features detection. It explains fundamental machine learning models used for image tagging, and how such models can be learned with Gradient descent. It propose solution with hierarchy for ImageNet and tagging images with attributes. MapReduce computing model is considered for learning on big data sets. In the last part it is described implementation, experimental and test results.

Application of Algorithms of Predictive Maintanence for RUL Estimation
Dvořák, Jan ; Brablc, Martin (referee) ; Dobossy, Barnabás (advisor)
The aim of this thesis is to acquaint the reader with the areas of predictive maintenance and its algorithms within its prognostic part. The remaining useful life of the system will be determined on the data sets and the performed experiment using prognostic models in accordance with the algorithms described in the research section. MATLAB and its other applications described in the work were used for data processing and modeling.

Proposal of SQL Database for a Drugstore Company
Zegzulka, Ivo ; Šťastníková, Adéla (referee) ; Kříž, Jiří (advisor)
This thesis deals with corporate database applications in SQL. The result should be applicable to business Iveta Šťastníková - production and distribution of toiletries, which is produced in dry goods. Primarily, should simplify operations such as stocking, invoicing, receipt and distribution of goods. First, we introduce the theoretical bases of work, and then move to the current state and the analysis itself. The result is a design solution that would meet the needs of the owner.

Fuzzy logic as a decision support in management practice
Svoboda, Jan ; Václavík, Lukáš (referee) ; Janková, Zuzana (advisor)
The thesis describes the process of evaluating internet domains for the purpose of automating the registration process. The set of measured results is used to support the managerial decision-making of XYZ company, utilizing advanced decision-making methods in the creation of the model. The model is developed using two programming environments, namely MS Excel and MATLAB. The decision-making tool fully corresponds to the current needs of the automation team, and the output is a final recommendation for the selection of suitable internet domains.

Media image of presidential candidates in Czech daily newspaper: Case study of media presentation of presidential elections in the USA, France and the Czech Republic
Presser, Šimon ; Kmeťková, Zuzana (advisor) ; Benda, Josef (referee)
This thesis focuses on media image of presidential candidates on both theoretical and empirical level. Theoretical part elaborates on agenda setting, salience, and framing. But mainly it focuses on summarization of current studies and methodological approaches to research of attribute agenda setting and creation of media image of political candidates. In total, sixteen studies from various media environments have been analysed. From these studies, set of universally applicable attributes have been derived, using the method of conceptual clustering. This set has been further extended by author's own categories and other attributes that emerged during empirical study of Czech daily newspapers. Result of the theoretical part is widely applicable set of 29 micro-attributes which five macro-attributes and two meta-attributes (as newly defined category) are consisted of. Besides the set of attributes, this thesis creates and defines brand new method of analysis through Coefficient of media affection which allows to evaluate the affective dimension of media image. The Coefficient is variable and can be tailored to the needs of specific research. Theoretical part, therefore, presents new and complex approach to analysing the media image of presidential candidates. The empirical part applies the methodology...
