The inherent variation of the same biometric makes it difficult to replace passwords directly with biometrics in a cryptographic scheme. Comparison of the true sets is a key step in biometric template matching or encryption. In FCS (short for fuzzy comparison scheme), an algorithm for biometric template matching is proposed based on fuzzy theory. The proposed method defines two fuzzy sets, measures the nearness between the two true sets, and selects an available threshold. Moreover, this method can be generalized into high dimension space and multi-set matching. Algorithm implementation and numerical example show that the fuzzy comparison scheme is effective and tolerant because of the threshold, which can make it more explicit for uncertainty.

Two existence results are presented on boundary value problem for discrete Hamiltonian systems with forcing terms. Methods used here is based on the Saddle Point theorem and the Least action principle. Moreover, in order to apply variational methods, a new action functional is constructed which is different from the usual action functional for periodic boundary condition.

This paper provides an effective web content-based image retrieval algorithm by using SIFT (Scale Invariant Feature Transform) feature. Different from other existing text-based web image search engines, this algorithm can be applied to content-based web image search engine effectively. SIFT descriptors, which are invariant to image scaling and transformation and rotation, and partially invariant to illumination changes and affine, present the local features of an image. Therefore, feature keypoints saved as XML files can be extracted more accurately by using SIFT than by color, texture, shape and spatial relations feature. To decrease unavailable features matching, a dynamic probability function replaces the original fixed value to determine the similarity distance of ROI (Region of interest) and database from web training images. The experimental results show that this method improves the stability and precision of image retrieval.

Studying on the KM4030 toolholder/spindle interface, through changing some factors such as magnitude of interference, clamping force, etc. the effects of different parameters on the performance of toolholder/spindle connection system were researched by means of the finite element method (FEM). The KM toolholder/spindle interface belongs to the highly nonlinear problem caused by interference fit and elastic coulomb friction. The distribution situation of the contact stress and elastic deformation was also given out based on the precise simulation results and the optimum magnitude of interference as well as clamping force was also recommended. It was expected the results could be used as theoretical basis and technical guide for application of KM tool shank in high speed machining (HSM).

In order to improve the quality of the restored image, a blind image restoration method is proposed, by estimating the blur function of the imaging model. Firstly, the parameters of the Gaussian point spread function (PSF) of the observed image are estimated. Through Wiener filter image restoration algorithm, multiple error-parameter curves are generated at different parameters. According to these curves, the size and standard deviation of PSF may be estimated. Then, utilizing the estimated PSF, the blurred image is restored through Wiener filter. Experimental results show that this PSF estimation method can estimate the parameters of Gaussian PSF accurately, and justify the fact that PSF estimation plays an important part in image restoration. The PSNR of the restored image has the highest PSNR around the real PSF, and the PSNR decreases when the estimated PSF is far away from its real value.
