Online diagnostics of machine tool MCV 754
Rázgová, Benedikta ; Huzlík, Rostislav (referee) ; Zuth, Daniel (advisor)
This master’s thesis deals with online diagnostics of the machine tool and marginal analysis of surface texture. The first part of the thesis deals with problems theoretically, there are described the machine tools, maintenance, methods of technical diagnostics, specifically online vibrodiagnostic systems and an overview of profile and area parameters. In the practical part, two test samples created under ideal and degraded conditions. In the practical part, two signal processing processes under ideal and degraded conditions are compared using signal analysis from an online vibrodiagnostic system and surface texture analysis. Part of the work is the evaluation of the performed analyzes and recommendations for practice.

NVH Analysis of Transmissions
Gazda, Silvester ; Zubík, Martin (referee) ; Prokop, Aleš (advisor)
This bachelor's thesis deals with the design of measuring noise and vibration of vehicle transmissions. First describes the main parts of the transmission. This is followed by a description of sources of vibration and noise, and their travel. Significant work is devoted to analysis of the frequency spectrum, of its creation and evaluation. It also includes a description of the measurement and the necessary equipment, along with a description of the basic principles of its functioning.

Finding the answer in the answers
Záhumenský, Jakub ; Vidová Hladká, Barbora (advisor) ; Bojar, Ondřej (referee)
Title : Searching for the answer in answers Author : Jakub Záhumenský Contact : zahumensky.jakub@gmail.com Department : Institute of Formal and Applied Linguistics Supervisor : Mgr. Barbora Vidová Hladká, Ph.D. Contact on supervisor : hladka@ufal.mff.cuni.cz Abstract : We design a question-answering system Interviewer that enables users to fictionally (virtually) interview this person by asking questions as similar as possible to questions that journalists have already asked. The interviews with a given person posted on the web are being collected as a corpus of (question, answer) pairs. The user asks his/her question and the Interviewer system searches questions in the corpus to provide the answer that belongs to the most similar question. Matching questions is based on the frequency analysis and on the applications coming from natural language processing, namely tagging and parsing. We work with the interviews with Vaclav Havel posted on his personal page.
