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.

Design of home automatic coffee machine
Kajstura, Bogdan ; Křenek, Ladislav (referee) ; Haltof, Vladimír (advisor)
The aim of this Bachelor’s thesis is to design an automatic coffee maker, which could be used in a household. Implementation of a modern technology as designing a machine, which would fulfill technologic and ergonomic requirements are main goals for this kind of product. Based on a wide analysis there was created an automatic coffee machine, which deals with these challenges in its own, original way.

Workplace for final testing of electronic transformers
Brýdl, Ondřej ; Fiala, Pavel (referee) ; Klusáček, Stanislav (advisor)
This article describes a complex suggestion for automatic tester machine for final testing of electronic transformers. There is also described universal device for measuring all types of transformers which are produced by ABB company. The main parameters of testing process are price, speed of measuring and high-quality measuring. The suggestion of the machine is optimized according to those parameters.

Comparison of the effect of the two-mass and hydraulic buffers on the impact of the self-loading rifle
Talanda, Jakub ; Blaťák, Ondřej (referee) ; Vančura, Jan (advisor)
The focus of this thesis are the effects of dual-body and hydraulic recoil buffers on measured recoil of an AR-15 type self-loading rifle. The first part explains the working principles of the rifle and both mentioned buffer designs and points out the sources of the recoil effect. A brief summary of contemporary knowledge and already conducted research into the problem follows. The second part describes an experiment in which the recoil force was measured using a force sensor placed between the rifle butt and shooter’s shoulder. At the end, outcomes of this research are discussed and results obtained for both buffer designs are compared.

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 detector of vehicle road accicents
Žurek, Jan ; Morský, Ondřej (referee) ; Dostál, Otto (advisor)
This master‘s thesis treat of car safety. It includes an introduction into already existing active and passive safety systems and briefly describes their basic principles. It also includes a description of basic principles of car electronic systems. It will acquaint us also with elementary calculations in the area of car crashing into a solid obstacle. On base of this information was developed and consequently realized development module of an automatic car accident alarm that transfers information using SMS messages to a cell phone. The message contains date, time and GPS coordinates of the accident and acceleration sensor readings in three axes.

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.
