Abstract:This paper introduces a semi-generative CAPP system for rotary type parts within a machinery works. Based on the idea of feature modelling, the system describes parts using shape recognition description, employs group technology codings etc. To express th

Abstract:In this paper, using the metod of mixed monotony, we study the initial value problem for first order functional differential equations, some new results are obtained.

Abstract:By solving two coupled one-dimensional poisson equations,the field and potential distributions between, rings are obtained-The influence of the device parameters such as ring spacing ring width, N-doping concentration,junction depth and surface charge den

Abstract:In this paper, we have studied the distortion properties for N-dimensional K-quasiconformal mappings and shown that the distortion in the neighborhood of the boundary points can be controled by the distortion in the boundary points by using quasihyperboli

Abstract:Based on the experimental data, a model Hamiltonian which is appropriate to describe doped quasi-one-dimensional halogen-bridged mixed-valence platinum complexes(HMPC's)was presented. Using Geen's function, the binding energy of polaron, which is a defect

Abstract:This paper analysed the theoretical shortcoming of the conventional method solving the oblique plane-block problem. The applicable range of Coulomb's friction Law in the fundamental problem are given.

Abstract:The article concentrated on the modifying effects of ion beam mixing, ion implanting and ion sputtering of hydrogen evolution electrodes. It was discovered that the four types of electrodes possessed excellent catalytic activity in both acid and alkaline
