Thanks to mummification, the physical remains of many rulers of ancient Egypt are still observable today and constitute a valuable source of information. By evaluating the age at death and sometimes elucidating the degree of kinship and circumstances of death, our knowledge of ancient Egyptian history becomes more precise. Different pathologic conditions have been found and the evolution of the mummification process can be seen through time.The most spectacular discovery was that of Tutankhamen’s mummy, the single totally undisturbed tomb, associated with a fabulous treasure.The mummy of Ramses II has been extensively studied, the only one that flew to Paris where an irradiation was delivered in order to eradicate a destructive fungal infection.The identification of Akhenaten’s mummy and the explanation for his peculiar appearance are still unsolved problems.Noticeably, many Royal mummies remain of uncertain identity or undiscovered hitherto.

To solve the problem that it is difficult to identify the cutting rock wall hardness of the roadheader in coal mine, a recognition method of cutting rock wall hardness is proposed based on multi-source data fusion and optimized probabilistic neural network. In this method, all kinds of cutting signals (the vibration signal of cutting arm, the pressure signal of hydraulic cylinders and current signal of cutting motor) are analyzed by wavelet packet to extract the feature vector, and the multi feature signal sample database of rock cutting with different hardness is established. To solve the problems of uncertain spread and complex network structure of probabilistic neural network (PNN), a PNN optimization method based on differential evolution algorithm (DE) and QR decomposition was proposed, and the rock hardness was identified based on multi-source data fusion by optimizing PNN. Then, based on the ground test monitoring data of a heavy longitudinal roadheader, the method is applied to recognize the cutting rock hardness, and compared with other common pattern recognition methods. The experimental results show that the cutting rock hardness recognition based on multi-source data fusion and optimized PNN has higher recognition accuracy, and the overall recognition error is reduced to 6.8%. The recognition of random cutting rock hardness is highly close to the actual. The method provides theoretical basis and technical premise for realizing automatic and intelligent cutting of heading face.
