Due to differences in overpass time of the\nvarious satellites, a trajectory model was used to move the CALIOP-derived\ndust heights in space and time to the IASI, GOME-2 and SCIAMACHY dust height\npixels. It is not possible to construct a unique dust-layer height from the\nCALIOP data...
II. DIRECTIONS: Identify the verb in each sentence as active or passive.Write A if the sentence is active, and P if it is passive.14. An estimated two-thirds of the downtown area of Los Angeles isdevoted to roads, parking lots and gas stations.15. Satellites are used to observe the ...
Structural vibration Passive control Active control Optimization Genetic Algorithm 1. Introduction Space missions that involve satellites with highly sensitive instrumentation packages perhaps raise the most challenging vibration control issues. Often these packages must be supported on structures where the vibrat...

But active remote sensing comes in many forms. For example, they can be satellites orbiting the Earth, helicopters in the air, or anything on the ground too. Just as long as it has an active sensor. Passive sensors Cameras arepassive sensorswhen the photographer does not use the flash. Bec...
However, in a move that may change the way we look a two-color imaging, researchers at the Northwestern University's Center forQuantum Deviceshave now found a way to integrate active and passiveinfrared imagingcapability into a single chip. This opens the way to lighter and simpler dual-mode...
Related to artificial active immunity:artificial passive immunity acquired immunity [ə′kwīrd ə′myün·ə·dē] (immunology) Resistance to a microbial or other antigenic substance taken on by a naturally susceptible individual; may be either active or passive. ...
A Semi-Active Nutation Damper for Spinning Prolate or Oblate Satellites Summary A nutation damper is proposed which will damp nutation of spinning prolate satellites. It consists of a compliant flywheel (a canister of fluid is suggested) spun by an electric motor at high speed in the opposite di...
