A new method, referred to as the full-recurrent-decimal-sequences (FRDS) method, is proposed to generate the pseudorandom integer strings and the pseudorandom s
A novel method to monitor optical signal to noise ratio using a Mach-Zehnder interferometer is introduced. The OSNR meter is composed of two 3dB couplers, one p
Gas hydrate, a new kind energy resources discoverd over the past ten years, has aroused much attention from many countries around the globe, because the gas hyd
The shape stiffness of mill m is defined as the crosswise rigidity of the unit width of steel plate, that is, m=k/b. By differentiating the steel plate crown eq
In ultra-precision cutting process, vibration is one of the key factors affecting the machining quality. In this paper, the damping methods of HCM-I Ultra-preci
The importance of the numerical model for sculptured part machining based on virtual environment is introduced. Meanwhile, the general frame of the numerical mo
