Charge changing processes (electron capture and loss) of light ions moving inside metals contribute significantly to the electron emission at intermediate and low impact velocities. An improved method for the description of screening of the moving ion in the electron gas developed by Nagy et al. [Nucl. Instrum. Methods 1996;B115:58.] and Lifshitz et al. [Phys. Rev. A 1998;57:200] will be used to determine...
This paper presents a new analytical modelling of suction cups used for window-cleaning robots. The modelling can be used when the force is parallel to the base surface of the suction cup. The basic idea of this analytical modelling is that the active area of suction cup will decrease as the air pressure decreases in the suction cup. The analytical modelling is based on the theory of elasticity. The...
