An improved particle swarm optimization scheme for codebook design is proposed in this paper. By sorting the training vector, we select the initial codebook to enhance the diversity of search, and add stagnant judging algebra to prevent the algorithm falling into a local optimum. The simulation results prove that the improved method is reasonable.

This paper presents an approach that uses conformal mapping to flattening a 3D surface to 2D plane. We propose an algorithm by traversing the mesh in a region growing way. The algorithm is greedy and begins with a seed triangle which can be chosen freely. In each operation, we develop a piecewise linear mapping function that is conformal. In addition, at first step, we initialize the planar triangle which corresponding to the seed triangle. The initialization ensures that the seed triangle flattening process produce no distortion. And in other steps, we reduce the distortion by unifying the vertices in the plane. Our approach is efficient and fast enough.

Federated identity management system interconnects distributed island of identity management systems with federated identity standards with single sign-on facility. In an open environment, such as those of a federated identity management system a user single sign-on credentials, can easily fall prey to identity theft, or unlawful information gathering. It may use either existing account or new account fraud. In this paper, we present scenarios related to identity theft, unlawful information gathering and tracking. We show the main issue of lack of platform trust in platforms involve in federated systems and discussed the consequences of respective threats on them. In an effort to present a holistic approach to handle security, trust and privacy, we propose a user requirement model involving these core issues for federated identities. These requirements include system trustworthiness, hardware protected key generations, usability, efficiency, identity information validity, privacy, accountability and system robustness. In our proposed model, Trusted Platform Module (TPM), is the fundamental component which ties and binds all communicating platforms together in authentication, verification and trustworthiness of the platform.

Locality Preserving Projection is a method which can extract the feature and reduce dimensionality effectively, which has been widely used in face recognition. However, it is also an unsupervised method, and it is an image vector-based method, needing to covert the face image into a vector. This conversion not only breaks the local structural information, but also brings lots of problems, such as the dimension of these converted vectors is too high and encounters the small sample size problem. And it is also an unsupervised method and has no directly relation to classification. In order to improve the performance of LPP, we present a method named Two-Dimensional Discriminant Locality Preserving Projection for extracting the feature and reduce dimensionality and apply it in face recognition. Experimental results on ORL and Yale databases suggest that the proposed 2DDLPP provides a better way to solve these problems and achieves lower error rates.

A new theory of gearing: high order contact meshing theory of gearing is presented in this paper. We believe that this kind of gear profile is most suitable in both the contact and bending fatigue strength. From careful analysis and deep going investigation, we think that it is the profile of equal conjugate curvature with high order of contact, and analyzed the forming principle of this kind of profile. In this paper our aim is to deduce the theory to form this kind of profile, and produce the proto type of reducer of this kind of spiral bevel gear.
