Analysis of email spam sources
Caha, Tomáš ; Kubánková, Anna (referee) ; Komosný, Dan (advisor)
The first part of this thesis deals with an approach of designing and developing of application for IP geolocation using various geolocation databases. Methods of geographical location of network devices and amount of available data provided by chosen commercial and freely accessible geolocation databases are presented. The data are summarized with focus on methods of obtaining information about IP addresses from various databases. In the paper there are also presented ways used to develop the Python application and its parts, which can be easily reused in other programs. The command line program was created to demonstrate that all parts of the developed application work properly. The whole application is freely accesible under the conditions of the MIT license, published on GitHub (https://github.com/tomas-net/ip2geotools/) and in the Python package index PyPi. The second part of this thesis deals with the description of cyberthreats and the use of developed application to mass geolocation of IP addresses that are listed in chosen freely accessible lists as sources of email spam or cyberattacks. Geographical analysis of cyberattacks sources shows countries of origin. Results of analysis are presented in graphs and maps.

Company's Information System Analysis and Modifications Concept
Zahradník, Martin ; Špatka, Petr (referee) ; Dydowicz, Petr (advisor)
This thesis deals with the analysis and design changes to a specific company information system under real conditions, and is therefore more practically oriented. The information system is studied both from the perspective of the end user, which is the focus, and in terms of operation and implementation of program solutions. The information system is studied as a whole in a broader context, not only in terms of applications (software), but also in terms of the flow of information, storage and organization of data, users, security, hardware, etc. It should serve to the company as a guide for the elimination of inefficient and / or risk areas, thereby helping to improve work productivity and employee satisfaction.

Tissue characterisation in spectral CT data
Poláková, Veronika ; Jan, Jiří (referee) ; Jakubíček, Roman (advisor)
This bachelor thesis deals with tissue characterisation in virtual monoenergetic images (VMI). Firstly, literature survey presents spectral CT which allows reconstructing VMI. Secondly, statistical evaluation of tissue CT numbers was made for all energies of VMI which were reconstructed. It was found that with growing energy of VMI CT number increases or decreases with different steepness depending on a type of tissue. As a consequence, the suitable VMI offer better contrast resolution between selected pairs of tissues, which enables better tissue segmentation and classification in these images.
