The technical framework of critical information infrastructure cybersecurity classified protection in this paper is established from the three levels of decision-making, managers and executives which ensures the information security technical framework of an organization is consistent with its strategic...

The boundary layer theory is proposed by German scientist Prandtl. When the fluid motion in the large Reynolds number, a thin layer will be concentration to produce in the fluid surface. Because the thin area is very close to the object surface in which the viscous force plays an important role, which...

The quality of flight performance directly determines the execution of flight tasks. For the establishment of a simple and effective methods and calculation of maneuver performance, a lot of work were completed. By the principle, method and steps of calculation maneuvering the aircraft flight performance...

No-reference image quality assessment is the future research direction in the field of image evaluation. A new no-reference image quality assessment based on the generalized evidence theory was proposed in this paper in order to deal with the measuring problem of the large scale samples under the optical...
