Abstract:Because there are lots of difficulties in mathematic modeling for uncertainty complex object, so it is not suitable to utilize traditional methods in some aspect such as identification, analysis, synthetical design and implementation. Especially, for the idea of system modeling, it is very different in comparison with traditional mathematic modeling, therefore, it is very difficult to study control problem for uncertainty system in technology and theory. On the basis of summarizing characteristics of uncertainty complex object, present to establish generalized control model, and apply intelligent control strategy to implement control effectively. In addition, authors also studied control algorithm and system structure. Engineering practice shows that it is effective and successful to establish generalized control model, and select intelligent control strategy for uncertainty control system.

Abstract:A novel genetic algorithm,simply written as REGA, is proposed with the idea to limit the number of repeating crossover and replacing the worst individuals of the current generation by the best ones of the former generation. The algorithm overcomes the premature phenomenon of the simple genetic algorithm. According to Markov's limitation theorem, we prove its global convergence,explore the properties of the genetic algorithm written as RSGA only based on repeating crossover,and provide a method to calculate the mathematic expectation on the absorption time for the two algorithms. Finally,the simulation shows that the algorithm REGA can solve the optimization problem containing more than one global optimal solutions,on one hand,while eliminating the drawback of local optimum and rapidly enhancing the average fitness. On the other hand, REGA is valuable for function optimization.

Abstract:Colour hologram making is an important part of research hologram display technology. Nowadays it has great influece upon improving the hologram display. Although different ways of producing colour hologram exist ,to get the better quality of colour hologram,a new way is found to produce it by diffraction colour separation method. The red,green and blue information code of a colour transparent film can be recorded on a black-and-white film with a three-colour grating. Monochromatic laser is used to reproduce at the same time the distributions of the recorded three-color colour information, and to record them on a holographic film to make a colour holographic image. The remarkable advantage is that there is no need to make three holographic images with information covered with colour selection, that the diffraction efficiency is high,and that the reproduced image is of clear and bright colour.

Abstract:Beth turbo codes and LDPC codes can achieve the Shannon limited performance. The constituent RSC codes in turbo codes are more structural and this lends the encoding problem easier with shift_register circuit.While the encoding of LDPC codes is performed via matrix multiplication, it is more complex than it appears for capacity_approaching LDPC codes. On the other hand,the soft_input soft_output BCJR algorithm,or the sub_optimal version of it,used for turbo_decoding is rather complex while sum_product algorithm used for LDPC decoding lends itself to parallel implementation and is computationally simpler. Combining the turbo codes encoding and LDPC decoding,a new scheme based on factor graphs and sum_product algorithm is developed, Which can reduce the decoding complexity of turbo codes greatly,and also has some guides in the designing of interleaver and the choosing of RSC constituent codes. Simulation shows the correctness of the scheme.

Cluster analysis firstly looks into the industry factor, company factor, profitability and pullulation of each stock, so people can discover the investment value through stock'immanent value which is decided by their fundamental characters.To gather the similar stocks,a synthetic evaluation index system is erected to measure the similarity of stock all-roundly and objectively. Cluster analysis can help investors hold the whole character of stocks, make certain of investing scale and suppose the possible variation of stock price.So it will be easier for investors to choose investing occasion.

Abstract:The problem of determination to weighting coefficient is a key and difficulty for combination forecast. A method of determining weighting coefficient based on rough set theory is showed in this paper. Determining weighting coefficient is translated into estimating significance of attributes among rough set. A relation data model about combination forecast is established. Knowledge systems are built through making attribute value into eigenvalue. Under data moving, the weighting coefficients of a combination forecast model are computed by analyzing the dependence and significance of forecasting method for the predicted object. The proposed approach overcomes the subjectivity of traditional determination to weighting coefficient, avoids computing linear or nonlinear extremum problem and makes combination forecast more objective. The validity of the proposed approach is verified with a case.

Abstract:The signal of brain activity is a non-stationary random signal including lots of physiology and disease information, which is of important action for doctors to judge pathological changes in brain. So the analysis and process of the EEG signals are always attended. In this paper, the authors take account of the time-frequency localization of wavelet transform and use multiresolution wavelet transform to detect EEG abnormal rhythms. The signals of different scales after EEG signals are transformed by multiresolution wavelet transform not only reflect the frequency information of the signals, namely the more great scale is the lower of the frequency of the signals,but also reflect the time information of the signals, namely EEG state at that time. The test results indicate that the abnormal rhythms of the EEG signals can be detected effectively if right wavelet basis is selected.
