We theoretically propose a new method for generating intense isolated attosecond pulses during high-order harmonic generation (HHG) process by accurately controlling electron motion with a two-color laser field, which consists of an 800-nm, 4-fs elliptica
A fixed abrasive technology combined with computer controlled optical surfacing is discussed, and a removal function model for multi-pellet polishing pad is established based on the removal function theory of planar motion. The parameters of the model, su
The difficulty of build-up area extraction is due to complexity of remote sensing data in terms of heterogeneous appearance with large intra-class variations and lower inter-class variations. In order to extract the built-up area from Landsat 8-OLI images
