Abstract: The traditional particle filter (PF) algorithm is well known for signal noise reduction processing, but it exists problems of particle impoverishment and cumulation of estimation errors.
To solve these problems, a RBF-PF algorithm for noisy signal reduction processing is proposed.
Signal noise reduction processing results.
Using the above two algorithms in signal noise reduction processing, to further validate RBF - PF algorithm has better de-noising effect than traditional particle filter algorithm by comparison.
Acknowledgement The experimental data is provided by the Reliability Research Lab in the Department of Mechanical Engineering at the University of Alberta in Canada.

By data-mining through large amounts of datasets, we showed that CNTs with small diameter, large number of walls, and crosslinks between walls can have high nominal tensile strength.
Data Mining with SOM With the ability of visualizing and categorizing information of materials, SOM is an integrated tool for material research [20].
The data mining approach with SOM aims to decrease the complexity of high-dimensional data, and reduce the high-dimension data to two-dimensional data.
To further understand the overall relation between geometrical properties of chirality, diameter, wall, crosslink and geometrical properties, we use SOM to dig on our data shown as Fig. 7.
Summary The relationship between mechanical properties and geometrical properties of CNTs were investigated by high-throughput molecular simulation and data mining technique.

The x-ray diffraction (XRD) data show that the reduction annealing process decreases c-axis length indicating successful removal of the excess oxygen.
Moreover, some studies claimed that the O(3) can be eliminated through the “modified” reduction annealing process [11–13].
Fig. 1 also describes that there are peaks that shift to a higher diffraction angle after the reduction annealing.
Similarly, the reduction annealing also provides an effect on the R distance.
