Циклостационарные модели радиосигналов с квадратурной амплитудной модуляцией
The article considers the methods of identification and graphic interpretation of the network structures of stock markets using the correlation analysis for the stock returns and stock indices. Based on the data of the Russian stock market the author shows that its basic structure can be obtained by building a maximum spanning tree of the correlation graph of earnings per share. The article also gives an example of applying the proposed approach to visualize the contagion dynamics of the crisis developments in the stock market.
In the course of this article, the necessity of planning the development of a regional transport infrastructure based on an analysis of the influence of existing infrastructure capacities on the socio-economic situation of the region. The list of indicators most objectively reflecting both the result of the economic activities of the subject of the Russian Federation and the current state of the transport infrastructure was determined, and a correlation analysis of the mutual influence of these indicators was carried out. At the final stage, the results were analyzed and interpreted
A method is developed to analyze the state of the interface in a multilayer metallic system; it is based on spectral analysis of a heat_transfer coefficient. A coefficient of correlation is used to find the relation between the spectral characteristics and the thermal conductivity of the interphase interface. The change in the coefficient of correlation induced by 10_MeV electron irradiation of a multilayer W–Mo system is studied.
Generalized error-locating codes are discussed. An algorithm for calculation of the upper bound of the probability of erroneous decoding for known code parameters and the input error probability is given. Based on this algorithm, an algorithm for selection of the code parameters for a specified design and input and output error probabilities is constructed. The lower bound of the probability of erroneous decoding is given. Examples of the dependence of the probability of erroneous decoding on the input error probability are given and the behavior of the obtained curves is explained.
This proceedings publication is a compilation of selected contributions from the “Third International Conference on the Dynamics of Information Systems” which took place at the University of Florida, Gainesville, February 16–18, 2011. The purpose of this conference was to bring together scientists and engineers from industry, government, and academia in order to exchange new discoveries and results in a broad range of topics relevant to the theory and practice of dynamics of information systems. Dynamics of Information Systems: Mathematical Foundation presents state-of-the art research and is intended for graduate students and researchers interested in some of the most recent discoveries in information theory and dynamical systems. Scientists in other disciplines may also benefit from the applications of new developments to their own area of study.
