In this paper, a condition monitoring and fault diagnosis method for rotating machineries using machine learning technologies including artificial neural network (ANNs) and support vector machine (SVMs) is described. The vibration signal is acquired from gearbox used in local power generation industry for analysis of potential defects. Wavelet packet transforms (WPT) and time domains statistical are used to extraction features, and the compensation distance evaluation technique (CDET) is applied to select optimal feature via sensitivities ranking. A comparative experiment study of the efficiency of ANN and SVM in predication of failure is carried out. The results reveal that the proposed feature selection and machine learning algorithms could be effectively used automatic diagnosis of gear faults.

In this paper, a maintenance algorithm for average-utility mining is proposed to update derived high average-utility itemsets in dynamic databases. It first calculates the count difference of modified itemsets and then partitions them into four parts according to whether they are high upper-bound average-utility itemsets in the original database and whether their count difference is positive or negative. Each part is then processed in its own way. Experimental results show the proposed maintenance algorithm runs faster than the two-phase approach for mining high average-utility itemsets in dynamic databases.

In this paper, we develop a feature measure method of the chess object from a chess image and identify the chess by using the features. Features are generated by calculating the distance between the contour of the character and the center of the chess object. We compare the features of input chess image with the standard database chess image to obtain a corrected chess identification results. There are two advantages compare with other methods: 1) Our method is robust from the 40 incline degree test. 2) Our method can resist the 20% pepper and salt noise attacks. In order to demonstrate the effectiveness of the proposed scheme, simulations under all kinds of various conditions were conducted. The experimental results show that our proposed scheme can exactly identify chess images 100% of the time.

This paper studies the structural design and analysis of a precision nono-positioning planar motion stage. First, the configuration design and specification of the planar motion stage are proposed. The stage consists of a stage base, a carriage supported by four air bearings, four linear motors, and a two-dimensional optical encoder. The planar motion stage has characteristics of high precision, long travel range, and nano-positioning accuracy. The travel range of the stage in X and Y directions are 50 mm × 50 mm. Then, structural characteristics of the stage are analyzed by finite element method (FEM). Deformation of the carriage due to inertial loading with 0.5g acceleration is analyzed. Natural frequencies and mode shapes of the carriage are analyzed and also checked by modal experimental test. Finally, optimum design method is applied to find the minimum weight of the carriage, and 34% of the carriage weight is reduced with maintaining the same carriage stiffness.

Six standard analytic coarse alignment methods and a direct method are compared via error analyses for strapdown inertial navigation system on stationary base. Although these methods are derived from the same measurements of the local gravity vector and the Earth rate, their error characteristics are not completely identical. The susceptibility of these methods to geographical latitude is examined, and a criterion for the election of an appropriate algorithm is established. Due to its high accuracy, computation efficiency and immunity to latitude uncertainty, the direct method is more suitable for practical applications. The results obtained from both simulation and real data test give a visual demonstration.

A novel dynamic model which characterizes the cooperative manipulation of a 3-PRS (Prismatic, Revolute, Spherical) parallel manipulator is developed. The coupling dynamics between the actuated legs is characterized by the constraint forces corresponding to three holonomic constraints. Based on the proposed model, the reaction forces can be effectively computed such that each leg can be considered as an independent subsystem after compensation of the reaction forces. Computer simulations on tracking circular trajectory are performed and a decentralized control algorithm is proposed to demonstrate the effectiveness using the developed model.

An elliptical function to model the nonlinear relation between 3D incoming rays and corresponding fisheye image coordinates is presented in this paper. Image coordinates are firstly lifted from a 2D plane to a five-dimensional quadratic space. And then the elliptical function model is built to use a linear combination of the distorted parameters of fisheye camera. Distorted parameters for fisheye camera can be estimated from the projection of 3D lines in the fisheye image. Finally, the fisheye image is corrected through the elliptical model parameters. Comparison experiments with synthetic data and real fisheye images using our model, Claus's model and Geyer's model are given, and experimental results show that our correction model is feasible and effective.
