The arithmetic correlation has been studied in the binary sequences and Boolean functions, the ideal arithmetic correlation sequences can be used in mobile communication authentication with their properties, such as the large number and the independent certification. In this paper, a new class of no-linear Boolean functions are described and their arithmetic correlation are analyzed. And based the...
Thermal error modeling is an effective approach to ensure the machining accuracy of NC machine tool by which the thermal error compensation could be implemented. The accuracy and robustness of the thermal error model are affected by the arrangement and identification of the temperature measuring points directly. This paper presents a new approach combining Grey Correlation and Kohonen network to optimize...
The ARMA forecasting model of time-series have established by using Liaoning province per capita GDP data from 1978 to 2008 In this paper. The economics increasing for the period of “the twelfth five years plan” has been forecasted and analyzed by using this model. the conclusions will provide with the help for Liaoning economics further development.
Based on wavelet transformation and chaos theory, low frequency noise in semiconductor laser is studied. The feasibility of chaotic noise model is discussed and prescribed in detail based on techniques of power spectrum, Lyapunov exponents and correlation dimension. And in theory, it also explains the reasons for this chaos phenomenon. The rigorous chaotic character of low-frequency noise in semiconductor...
