In the complex case, the distributions for the complex variables were often spherically symmetric, so only the modulus was interesting.Thus a nongaussianity measure based on the modulus only was used[12]: (4) where G is a smooth even function, and W is a M order complex-valued vector and, and the data Z is whitened.
Acoustics camera consists of one microphone array, one data recorder, one PC and a software called NoiseImage.
Through FFT to those stored data in 48 channels, they became complex-valued signals in frequency domain.
Considering large data and complexity of frequency components, we set the upper limit of iterative frequency as 3000 while analyzing and processing the tested signals with FICA.
Conclusions 1) Noise signals from excavator engine submit to super-gaussian distribution and meet needs of ICA. 2) Principal frequencies of independent components can be extracted effectively from noise signals by use of complex-valued ICA in frequency domain. 3) By comparing principal frequencies of independent components with the result of modal analysis based on Ansys, noise sources can be found properly. according to the result of noise sources recognition, efficient project was proposed and effect of noise reduction is obvious.

Fig.1 Snow load caused the roofs collapse Fig.2 A rink in German was destroyed by snow The present research situation of snow distribution on the roofs The main theory of snowdrifting The snow loads on the low rise roofs were investigated from1940 based on snow data.
The basic process is that arrange some observation dots first and then measure the snow depth by ruler at these points, finally to get the regularity of snow distribution on the roof by statistic data.
Beyers(2003)[9] obtained the related data like wind speed section by observing snowdrift around outdoors modeling of SANAE IV research station in Antarctica.

Thin continuous oxide layer formed on the matrix has composition (according to XSA) corresponding to the oxide based on boron-alloyed aluminium and nickel (Figs. 1a-c, zone 1). 1 2 1 3 1 4 5 10µm 10µm 8µm а b c Fig. 1 Microstructure of compact materials after oxidation at 500 °С for 90 min in air: (a) NiAl-15% CrB2; (b) NiAl-15% TiB2 and (c) NiAl-15% ZrB2 The oxide layer (with oxygen content 5 at %) was found on the surfaces of boride grains in case of NiAl-15% CrB2 material (Fig. 1a, zone 2) corresponding (XSА data) to complex oxides on the basis of Cr (45 аt %) and B (50 аt %).
Homogeneous tribolayer (thickness 4-12 µm) on top of Cr2O3 is composed of complex oxides on the basis of Ni, Al and Cr ((NiCrAl)xOy, XSA data, Fig. 4a and b), transferred from the counterbody surface (NiAl).

In particular, the data on high temperature oxidation indicate that NiAl-ZrB2 material had the most intensive formation of oxide phases and it had also had the most intensive wear (Fig. 1 and 2).
Thin oxide layer with high mechanical properties formed on NiAl-CrB2 composite surface provides the highest wear resistance due to reduction of friction (act as solid lubricant) and due to possibility of its transfer to the other areas of the coating providing improved protection and increased wear resistance.
