Prediction of the Technical State of the Key Components of the System and Indentification of the Problems

Diplomová práce se zabývá zjišťováním technického stavu strojů Maplan, Desma a porovnáním se strojem Rep ve firmě SumiRiko AVS Czech s.r.o. Drnovice. Cílem práce je zhodnotit stav výše uvedených strojů s využitím metod technické diagnostiky a určit doporučení pro budoucí provoz. Praktická část se zaměřuje na analýzu olejového média a pomocí tribodiagnostostických rozborů hodnotí parametry maziva a jeho degradaci. Dále se provede experiment s teplonosným olejem, který prokáže, jak se v čase mění jeho stav. Pomocí vibrodiagnostiky se analyzují vibrační signály. Na základě výsledků a následného vyhodnocení se zvolí vhodná doporučení.The diploma thesis deals with the technical state of the machines Maplan, Desma and comparing with the Rep machine at SumiRiko AVS Czech s.r.o. Drnovice. The aim of the thesis is to evaluate the state of the above-mentioned machines using technical diagnostic methods and to determine recommendations for future operation. The practical part focuses on the analysis of the oil medium and evaluates the parameters of the lubricant and its degradation by means of tribodiagnostic analyzes. In addition, an experiment with a heat-resistant oil is performed to show how its status changes over time. Vibration signals are analyzed by vibro-diagnostics. Based on results and subsequent evaluation, appropriate recommendations will be selected.340 - Katedra výrobních strojů a konstruovánívýborn

Estimation of Single-Gaussian and Gaussian mixture models for pattern recognition

Single-Gaussian and Gaussian-Mixture Models are utilized in various pattern recognition tasks. The model parameters are estimated usually via Maximum Likelihood Estimation (MLE) with respect to available training data. However, if only small amount of training data is available, the resulting model will not generalize well. Loosely speaking, classification performance given an unseen test set may be poor. In this paper, we propose a novel estimation technique of the model variances. Once the variances were estimated using MLE, they are multiplied by a scaling factor, which reflects the amount of uncertainty present in the limited sample set. The optimal value of the scaling factor is based on the Kullback-Leibler criterion and on the assumption that the training and test sets are sampled from the same source distribution. In addition, in the case of GMM, the proper number of components can be determined

System for fast lexical and phonetic spoken term detection in a czech cultural heritage archive,”

Abstract The main objective of the work presented in this paper was to develop a complete system that would accomplish the original visions of the MALACH project. Those goals were to employ automatic speech recognition and information retrieval techniques to provide improved access to the large video archive containing recorded testimonies of the Holocaust survivors. The system has been so far developed for the Czech part of the archive only. It takes advantage of the state-of-the art speech recognition system tailored to the challenging properties of the recordings in the archive (elderly speakers, spontaneous speech, emotionally loaded content) and its close coupling with the actual search engine. The design of the algorithm adopting the spoken term detection approach is focused on the speed of the retrieval. The resulting system is able to search through the 1,000 hours of video constituting the Czech portion of the archive and find query word occurrences in the matter of seconds. The phonetic search implemented alongside the search based on the lexicon words allows to find even the words outside the ASR system lexicon such as names, geographic locations or Jewish slang

Some Duties of Civil Service Bodies in the Field of Economic Measures for Crisis States, in Favour of Inhabitants.

A society should work on the basis of dividing activities among individuals so that they can complement each other and master everything as a whole. We can see such a task division in the field of economic measures for crisis states among civil service bodies and local authorities. Each crisis state is able to check the system, to prove rightness of the steps on the one hand and warn of possible imperfections on the other. The first part of my Bachelor´s work is aimed at presenting basic tools of public administration and civil service bodies in the field of economic measures which could be used in the state of emergency. Other parts are focused on the review of legislative tools tried and tested in the crisis states. To get the data about public awareness of crisis management in a locality, anonymous questionnaires were used. There were mostly villages affected by the 2009 local floods in the administrative area of České Budějovice with up to 2000 inhabitants surveyed. The questionnaires consisted of three parts. The first part analysed the respondents, the second presented the respondent awareness of crisis management and the the third contained questions concerning personal experience with crisis management. The research findings were processed and arranged in graphs and subsequently used in discussion and conclusion
