This paper develops a method for automatically incorporating variable selection in Fisher’s linear discriminant analysis (LDA). Utilizing the connection of Fisher’s LDA and a generalized eigenvalue problem, our approach applies the method of regularization to obtain sparse linear discriminant vectors, where “sparse” means that the discriminant vectors have only a small number of nonzero compone...

The features of a newly developed multi-dimension squeezed penetration piling machine are presented in this paper. The simulation model is built and the squeezing mechanism is tested under simulation environment. With the simulation method key design parameters are predicted at the early design stage; the development cycle can be shortened; and the product quality can be improved.

The equilibrium properties of spherulite assemblies in lyotropic lamellar phases are studied within both elastic and statistical models. Following previous models, the spherulites are assumed to be stabilized by their positive Gaussian curvature. Our model predicts that the spherulites should adopt a regular crystalline piling if their core energy E~ is much larger than k~ T, or a liquid-like p...
