Analýza využití nových technologií pro vizuální komunikaci a jejich společenský dopad / Analysis of the use of new technologies for visual communication and their social impact

Kadlecová, Petra January 2012 (has links)
The work focuses on the analysis of new technologies, which are used in visual communication. This is especially the description, characterization and their use. Another section focuses on social trends that permeate contemporary Western society, and their relationship with new technologies in the field of visual communication. It deals therefore also examines the social changes and changes in the perception of individual development and dissemination of new technologies causes. Describes the important role of visual communication in today's world and the changes in society due to widespread use of modern technology. The aim is to make the analysis and therefore a comprehensive overview of new technologies and their use in the field of visual communication. Finally, the work seeks to estimate the next direction of new technologies in the field of visual communication and create a prediction of further development in the future.

Využití umělé inteligence k monitorování stavu obráběcího stroje / Using artificial intelligence to monitor the state of the machine

Kubisz, Jan January 2020 (has links)
Diploma thesis focus on creation of neural network’s internal structure with goal of creation Artificial Neural Network capable of machine state monitoring and predicting its remaining usefull life. Main goal is creation of algorithm’s and library for design and learning of Artificial Neural Network, and deeper understanding of the problematics in the process, then by utilising existing libraries. Selected method was forward-propagation network with multi-layered perceptron architecture, and backpropagation learning. Achieved results was, that the network was able to determine parts state from vibration measurement and on its basis predict remaining usefull life.

Rozeznávání vzorů v dynamických datech / Pattern Recognition in Temporal Data

Hovanec, Stanislav January 2009 (has links)
This diploma work initially conduct research in the area of descriptions and analysis of time series. The thesis then proceed to introduce the problems of technical analysis of price charts as well as indicators, price patterns and method of Pure Price Action. The method Pure Price Action is demonstrated in this work in two practical examples of its application to real businesses with a view to discovering and analyzing price patterns, as well as analysis and prediction of future price and financial evolution. This analysis is an introduction to the processes of successful business, following on from this we discuss the theme of Pattern Recognition and the Instance Based Learning method. The practical aspect of this work is carried out with the aid of a MATLAB applied algorithm for the analysis of the price pattern Correction for sale and purchase in dynamic time segments, specifically in trading price graphs, like those used for commodities or stock trading. For the analysis of time series we use the Pure Price Action method. The Instance Based Learning method is used by the algorithm to recognize price patterns. The created algorithm is verified on real data of a 5 minute time series of the US Dow Jones price charts for the years 2006, 2007, 2008. The achieved accuracy is evaluated with the aid of Equity Curves.

Zhodnocení výhodnosti užití zpětného leasingu investice financované dlouhodobým úvěrem / Expedience evaluation of use of reverse leasing of investment financed by long credit

Váhalová, Marta January 2007 (has links)
The master’s thesis is aimed at the expedience evaluation of use of a reverse leasing of investment financed by a long credit. First of all the fundamentals of a leasing, a long credit and the present state of the Czech leasing market are reviewed. The target of the effort is the comparison of several reverse leasing’s options as a source of financing.

Využití umělé inteligence na kapitálových trzích / The Use of Artificial Intelligence on Stock Market

Barjak, Maroš January 2013 (has links)
The thesis deals with design, implementation and optimization of a model based on artificial intelligence and neural networks, which is able to predict future time series prices on a stock market. Main goal is to create an object oriented application for successful future trend prediction of financial derivatives with the use of cooperating methods such as Hurst exponent evaluation and automated market simulation.

Využití fraktální a harmonické analýzy k charakterizaci fyzikálně chemických dějů / Characterisation of the Physical Chemical Processes Using the Fractal and Harmonic Analysis

Haderka, Jan January 2010 (has links)
Existuje mnoho různých způsobů jak analyzovat disperzní systémy a fyzikálně chemické processy ke kterým v takových systémech dochází. Tato práce byla zaměřena na charakterizaci těchto procesů pomocí metod harmonické fraktální analýzy. Obrazová data sledovaných systémů byly analyzovány pomocí waveletové analýzy. V průběhu práce byly navrženy různé optimalizace samotné analýzy, převážně zaměřené na odstranění manuálních operací během analýzy a tyto optimalizace byly také inkorporovány do softérového vybavení pro Harmonickou Fraktální Analýzu HarFA, který je vyvíjen na Fakultě chemické, VUT Brno.

Webový server pro predikci 3D struktury proteinu / Web Server for Protein Structure Prediction

Votroubek, Lukáš January 2013 (has links)
This work deals with proteins, especially with their structure and kinds of tertiary, or 3D, structure prediction. Tertiary structure prediction is very important for function prediction of this vitally important substance. Bioinformatics do this prediction much more effective and faster, because classical methods of structure prediction directly from molecule are very expensive and slow. On the other hand they are much more exact. Objective of this thesis is to describe tertiary structure prediction methods, describe used tools and possibility of automatic communication with them.  Next objective is describe implementation of server, that will serve to protein engineers for more effective finding of information about tertiary structure from more servers without requesting each of them separately. Results of testing will be described in this work too.

Předpovídání vývoje více časových řad při burzovním obchodování / Prediction of Multiple Time Series at Stock Market Trading

Palček, Peter January 2012 (has links)
The diploma thesis comprises of a general approach used to predict the time series, their categorization, basic characteristics and basic statistical methods for their prediction. Neural networks are also mentioned and their categorization with regards to the suitability for prediction of time series. A program for the prediction of the progress of multiple time series in stock market is designed and implemented, and it's based on a model of flexible neuron tree, whose structure is optimized using immune programming and parameters using a modified version of simulated annealing or particle swarm optimization. Firstly, the program is tested on its ability to predict simple time series and then on its ability to predict multiple time series.

Predikce časových řad pomocí statistických metod / Prediction of Time Series Using Statistical Methods

Beluský, Ondrej January 2011 (has links)
Many companies consider essential to obtain forecast of time series of uncertain variables that influence their decisions and actions. Marketing includes a number of decisions that depend on a reliable forecast. Forecasts are based directly or indirectly on the information derived from historical data. This data may include different patterns - such as trend, horizontal pattern, and cyclical or seasonal pattern. Most methods are based on the recognition of these patterns, their projection into the future and thus create a forecast. Other approaches such as neural networks are black boxes, which uses learning.
