The atmospheric perspective effect is a physical phenomenon relating to the effect that atmosphere has on distant objects, causing them to be lighter and less distinct. The exaggeration of this effect by artists in 2D images increases the illusion of depth thereby making the image more interesting. This paper addresses the enhancement of the atmospheric perspective effect in landscape photographs...
4D reckoning is a core technology to the next generation of air transport management. This paper mainly do research on the aircraft dynamics model under a given flight profile of different phases of flight performance and aircraft performance differences. Then, proposed two models: state switching transition model between different phases of flight, System evolution model under the continuous variation...
The traditional dry beneficiation such as the pneumatic separator, the pneumatic jig and the air table, has low efficiency and with heavy dust pollution, can't meet the requirements of the modern beneficiation. The technology of the air-dense medium fluidized bed concentration, an effective dry beneficiation, can solve the above problems. This paper presents the separation principal of the air dense...
