Surface plasmon polaritons is a kind of electromagnetic oscillation coupled with the undulation of charge intensity, which is excited at the interface between metal and dielectric. With the properties of near-field enhancement and short wavelength, surface plasmon polaritons play an important role in nano-photonics. We use an unambiguous definition to represent the local density of electromagnetic...
To satisfy high speed and high precision machining for steam turbine blade, an improved acceleration/deceleration (ACC/DEC) interpolation algorithm based on the NURBS curve is proposed as the blade curvature radius changes greatly. The interpolation algorithm in this paper takes the easily overrunning chord error and maximum acceleration into consideration, and uses ACC/DEC control in the sensitive...
Planning of the mobile robot is one of the core research areas which is complex, binding and non-linear. Ant colony algorithm is an intelligent optimization algorithm developed in recent years. Aiming at the problems of the ant colony algorithm such as slow convergence speed and long computation cycle, in order to improve the efficiency of route planning, proposed using improved ant colony algorithm...
In order to improve the machining efficiency and precision of steam turbine blade, the accurate mathematics model of complex blade is built with non-uniform rational B-spline. An ameliorative adaptive feed speed interpolation algorithm for an non-uniform rational B-spline curve is proposed aim at blade curvature radius great change. The faster feed speed is adopt to increase the machining efficiency...
