Performance Monitoring of MES PHARIS
Ondráček, Aleš ; Hruška, Martin (referee) ; Smrčka, Aleš (advisor)
This diploma thesis deals with the performance monitoring of automated development processes and performance testing of the MES PHARIS system. The main scope of thesis is the collection of data on tasks performed on automation servers DevOps and Jenkins, processing of this data and their subsequent visualization. The second part of the diploma thesis deals with the processing of data from performance testing and their appropriate representation using visualization. The core technology that is used is ELK Stack.

Performance Data Collection of MES PHARIS
Oháňka, Martin ; Hruška, Martin (referee) ; Smrčka, Aleš (advisor)
This master's thesis deals with monitoring of automated tasks on integration servers and obtaining data from these tasks. Another area of this work is performance testing and to obtain information about hardware utilization from it. Thanks to this, it is possible to perform performance analysis of the implemented solution from different performance perspectives. The result of this master's thesis is a software solution that can obtain data about tasks from DevOps and Jenkins integration servers. In the area of performance testing, there is created a solution for parallel execution of tasks. The output of this work an output passed in JSON format. The data is then transferred to the Elastic platform, specifically Logstash, where it is subsequently visualized using Kibana. The Beat platform is used to collect data from performance testing. The solution was applied to the production information system MES PHARIS of the UNIS company.

Filtering of denial-of-service attacks
Klimeš, Jan ; Blažek, Petr (referee) ; Gerlich, Tomáš (advisor)
This thesis deals with filtering selected DDoS attacks on denial of the service. The the toretical part deals with the problems of general mechanisms used for DDoS attacks, defense mechanisms and mechanisms of detection and filtration. The practical part deals with the filtering of attacks using the iptables and IPS Suricata firewall on the Linux operating system in an experimental workplace using a network traffic generator to verify its functionality and performance, including the statistical processing of output data from filter tools using the Elasticsearch database.

Semantic Similarity of Articles
Veselovský, Martin ; Otrusina, Lubomír (referee) ; Kouřil, Jan (advisor)
This bachelor's thesis deals with modelling of structure of semantic relationships among articles in English language. There are introduced existing methods of articles representation and computation of similarity. The base method is vector space model, which represents document as vector of words. There are given weights of importance to these words using TF-IDF method. Next, there are described advanced methods of modelling, Latent semantic analysis (LSA) and Latent Dirichlet allocation (LDA). This thesis also deals with articles, which are semantically annotated, while weights of annotation words are computed by Stochastic Gradient Descent method. Evaluation of results takes place on the prepared test corpus of documents to which there is reference similarity evaluation.

Automatically Updated Bibliography
Valo, Boris ; Škoda, Petr (referee) ; Smrž, Pavel (advisor)
This paper describes the development of application for automatically updated bibliography. Nowadays, many Internet users search informations they need, this is important especially in sets of scientific publications and articles. The aim of this thesis is convenient tool for users to create their own portal. This is achieved by storing documents and their subsequent search using ElasticSearch. Retrieval is made by Boolean queries and additional search using similarity search tool MoreLikeThis. At the end of this thesis is described the way of testing and evaluation of retrieval.

Web App for Capturing New Shots of Historical Photographs
Sikora, Martin ; Brejcha, Jan (referee) ; Čadík, Martin (advisor)
The aim of this diploma thesis is to design and implement a web application focused on rephotography management. Analyze existing solutions, create list of features and simple graphical user interface. It also includes a design of API structure to communicate with the mobile application. Essential application requirements include adding photos on a map and combining different photos in a photo editor with enhanced auto-alignment features.

Automatically Updated Web Portal
Staněk, Petr ; Škoda, Petr (referee) ; Smrž, Pavel (advisor)
This bachelor's thesis is dedicated to the design and implementation of an automatically updated web portal that tries to resolve the shortcomings of the portals filled with other people's content. Furthermore, it presents a comparison of the existing scientific portals, it discusses the problems of extraction, saving and searching for information. General mechanisms are demonstrated on the European research projects portal, which removes the shortcomings of CORDIS, the official information portal for European research and development. The thesis takes the existing product as a prototype and its aim is to improve the quality of the extraction and extend the system to detect any potential problems and notified an administrator of them. This was achieved by increasing the robustness and speed of the extractor, by registering all the important events associated with the extraction and, on the other side, the implementation of the separate administrator section of the web portal, which informs the administrator about problems and offers the problem-solving devices.

Extending Functionality of European Project Portal
Vorobiev, Nikolaj ; Doležal, Jan (referee) ; Smrž, Pavel (advisor)
This thesis is based on 2 previous theses, complements and expands the last of them. The primary objective is to take existing source files, study, modify and use them for the purpose of running and updating the system. It is a necessary intermediate step, which the previous thesis solved partly. The secondary objective is to expand the system focused on improving the navigation, creating relations between the similar existing system entities, metasearching for relevant resources according to user requirements, extracting and storing new unique information about entities in the system, which is not provided by the current source. The result of the thesis is a running system, filled with fresh data, prepared and improved for system users. The source code of the system is refactored, became more readable and is ready to be extended. The metasearch engine is created, in modern Perl 5. The source code of the engine is portable and scalable, which allows easy integration into other systems.
