System for automatic evaluation of email messages
Frkal, Jan ; Červenka, Vladimír (referee) ; Koutný, Martin (advisor)
This diploma thesis deals with the design and realisation of system for automatic evaluation of e-mail messages. The system works with PHP language and MySQL database. It also allows automatic synchronisation. During the synchronisation e-mail messages are downloaded and saved using IMAP or POP3 protocol. Subsequently, the messages are analysed. During the analysis the reports are classified into types, according to pre-defined keywords. The system also works with black lists and white lists. If the sender of an e-mail is during the synchronisation found in the blacklist, that e-mail will be skipped. On the contrary, if the sender of an e-mail is found within the white list, that e-mail will be excluded from keyword matching and from the list is type and category loaded. Most of the values from the carried out evaluation of the e-mails can be clearly seen in advanced statistics. Pie charts and numerical statistics are available. Access to the system is protected by a login. Therefore, login can only registered users.

Agreements and Disagreements between Automatic and Human Speaker Recognition
Valenta, Jakub ; Matějka, Pavel (referee) ; Rohdin, Johan Andréas (advisor)
Tato práce se zabývá problémem rozpoznáváním mluvčího. Uvedený pojem je definován a doplněn o jednotlivé metody, které s ním souvisí. Cílem práce je poukázat na shody a rozdíly mezi lidským a automatickým procesem rozpoznávání mluvčího. V úvodu práce jsou popsány teoretické poznatky z obou zmíněných oblastí, tj. na jaké aspekty lidské řeči se zaměřuje člověk, resp. automatický systém. Následně je provedeno několik experimentů, které mají za úkol srovnat tyto dvě metody. Tyto experimenty jsou vyhodnoceny tak, že je možné pozorovat, které testovací úlohy dokáže lépe vyřešit člověk, aby následně bylo možné tyto poznatky použít ke zlepšení funkce automatického systému. V závěru práce je takovýto návrh na zlepšení automatického systému předveden a otestován. Testování proběhlo úspěšně a byla zaznamenána vyšší přesnost při vyhodnocování. Takový výsledek tedy může být užitý v dalších výzkumech a umožnit tak další vývoj v oblasti automatického rozpoznávání mluvčích.

Automatic Testing of JavaScript Restrictor Project
Bednář, Martin ; Pluskal, Jan (referee) ; Polčák, Libor (advisor)
The aim of the thesis was to design, implement and evaluate the results of automatic tests for the JavaScript Restrictor project, which is being developed as a web browser extension. The tests are divided into three levels - unit, integration, and system. The Unit Tests verify the behavior of individual features, the Integration Tests verify the correct wrapping of browser API endpoints, and the System Tests check that the extension does not suppress the desired functionality of web pages. The System Tests are implemented for parallel execution in a distributed environment which has succeeded in achieving an almost directly proportional reduction in time with respect to the number of the tested nodes. The benefit of this work is detection of previously unknown errors in the JavaScript Restrictor extension and provision of the necessary information that allowed to fix some of the detected bugs.

Basic measurement of dynamic properties of bipolar and unipolar transistors
Lang, Radek ; Šotner, Roman (referee) ; Dřínovský, Jiří (advisor)
The aim of this bachelor’s thesis is to describe the dynamic parameters of semiconductor devices. The other aim is to build a measuring workplace, on which is possible to carry out measurement of dynamic properties of bipolar and unipolar transistors. The bachelors’s thesis also solves a design and a production of an universal product, on which measurements are carried out. Individual measurement is automated and individual devices are connected to the product and results are controlled by computer analysis.

Administration of ICT Environments Using Autonomous Solutions
Boštík, Filip ; Chromčák, Michal (referee) ; Dydowicz, Petr (advisor)
This master's thesis shows an example of reactive server automation in ICT environments. There is a description of solution for specific problem in the AIX operating system which is implemented in an automation suite IPC. Analysis of current situation contains description of properties of the operating system AIX, the examined problem as well as of the IPC tool which is used for implementing this solution. After the description of the implemented solution there is also an economic evaluation of the entire thesis.

Proposal and implementation of procedures for automated response of security incidents
Hons, Kamil ; Safonov, Yehor (referee) ; Martinásek, Zdeněk (advisor)
This diploma thesis deals with the development of proposals for procedures for dealing with security incidents, both from a theoretical and practical point of view. Three generic scenarios in the form of graphical diagrams, designed in Inkscape program, were created as a theoretical template for the automatic handling of security incidents. The first proposed scenario suggests a general procedure for dealing with an event in which an email attachment is marked as suspicious. The second scenario serves as a suggested procedure for handling an event, where an untrusted external IP address is suspected to be communicating with a local one. The third scenario then suggests an investigation procedure for events, where a suspicious file on a remote device needs to be investigated. Based on these created scenarios, a practical implementation of procedures for automized solving of security incidents was performed and documented in the Python programming language within the Splunk Phantom environment. As part of the documentation of the scenario implementation, two audiovisual demonstrations were created to illustrate the designed environment and the functionality of the implemented scenarios using programs such as OBS and Blender. The individual implementations are tested at the end of the thesis by running them automatically over events from a defined time range. The results are clearly analyzed in the form of tables to determine the success of these scenarios, which is based on checking how the analysis results differ from the original assumptions. Based on the analysis, the practical implementations of the scenarios have been modified to ensure that their output matches with the assumption. Thus, results are three proposed, tested and analyzed scenarios, which can further serve as a basis for specific implementations in a corporate information system. The actual implementation of the theoretical scenarios was carried out within a testing environment and the work includes a description of the communication and a setup of the environment. Finally, the results of the individual scenarios were described.

Automatic construction of semantic networks
Kirschner, Martin ; Pecina, Pavel (advisor) ; Holub, Martin (referee)
Presented work explores the possibilities of automatic construction and expansion of semantic networks with use of machine learning methods. The main focus is put on the feature retrieving procedure for the data set. The work presents a robust method of semantic relation retrieval, based on distributional hypothesis and trained on the data from Czech WordNet. We also show the first results for czech language in this area of research. Part of the thesis is also a set of software for processing and evaluating of input data and a overview and discussion about its results on real-world data. The resulting tools can process data of amount in orders of hundreds of millions of words. The research part of the thesis used Czech morphologicaly and syntacticaly annotated data, but the methods are not language dependent.
