A method for testing water droplet shedding ability of a surface of an aircraft wing includes: blowing air toward a surface of a cylindrical member in an airflow direction perpendicular to an axial direction of the cylindrical member, the cylindrical member simulating the wing and having water-related surface characteristics that differ across a predetermined boundary position in a circumferential direction; supplying a water droplet to a portion of the surface of the cylindrical member on a leading edge side with respect to a flow of the air; and capturing an image of the water droplet that moves on the surface of the cylindrical member across the boundary position due to the flow of the air.

The present disclosure is a toy that has hexagonal rings with letters on each hexagonal side that can be rotated to spell words that are present on cards that the users views, the hexagonal rings are removable and replaceable on a lift bar that fits into opening the vertical supports, to facilitate the rotating of the letters the inner hexagonal ring is offset from the letters on the outer ring so the letters fall into place, the variety of words that can be spelled are increased with sets of three hexagonal rings, each with their individual colors for their letters, and three sets of cards with words to spell, each with a color corresponding to the color of one of the set of hexagonal rings.

The systems and applications for generating the augmented reality (AR) images are disclosed. The system includes a processing module and a digital microscope module having a plurality of camera units, and the processing module tracks and parses the user's motions to generate the related control signals, the virtual objects composed to form the AR images according to the received instant images of the observed objects captured by the digital microscope module. Moreover, the processing module generates and outputs the AR images composing of the instant images and the user interface (UI), icons, objects, video and/or information related to the interactive applications while the display mode switch or the real-time tutorial and sharing is triggered.

The present invention provides a system and a method for simulating formation and evolution of a deep-sea cold seep ecosystem. Simulation of the cold seep ecosystem is realized and a unit above seabed interface, a seabed interface ecosystem simulation unit, and a subsea interface unit is formed through the system, which provides environmental conditions for evolution of the cold seep ecosystem. At the same, the primary succession and secondary succession of the ecological cold seep system are simulated through the environmental condition control equipment, the sampling cabin, and the seabed current injection system, and the formation environment of the system is remodeled in situ, thereby effectively shortening the period of field observation to research the cold seep ecosystem. The system can not only observe formation and evolution of the cold seep ecosystems, but also grasp key feature points in the development process for the real-time sampling and analysis, which broadens the depth of the cold seep ecosystem research.
