Record 1 2019-12-16

English

Subject field(s)
  • Ecosystems
  • Oceanography
  • Hydrology and Hydrography
CONT

The German Remote Sensing Data Center(DFD) of the German Aerospace Center(DLR) analyses and quantifies change and dynamics in coastal areas, such as coastal urbanization expansion, land subsidence, coastline change, sea level rise and expected impacts, coastal vulnerability and exposure, … the threat to coastal protective ecosystems, such as wetlands and mangroves...

French

Domaine(s)
  • Écosystèmes
  • Océanographie
  • Hydrologie et hydrographie
CONT

Le Centre de données de télédétection allemand (DFD) du Centre aérospatial allemand (DLR) analyse et quantifie les changements et les dynamiques qui s'opèrent dans les zones côtières. Il se penche, par exemple, sur l'expansion de l'urbanisation côtière, l'affaissement du sol, les changements de lignes côtières, l'élévation du niveau de la mer et les conséquences attendues, la vulnérabilité et l'exposition des côtes, [...] les menaces qui pèsent sur les écosystèmes côtiers protecteurs (notamment les terres humides et les mangroves) […]

Subject field(s)
  • Urban Development
  • Population Movements
OBS

Even more significant than the increasing density of urban population is its correlative tendency to overflow,... to extend over wider areas... The most evident process, looking at community growth ecologically, is that of radial expansion from the center.

English

Subject field(s)
  • Energy (Physics)
  • Atmospheric Physics
DEF

Energy emissions resulting from the generation of hydromagnetic waves in the outer atmosphere.

CONT

Subsequent substorm onsets are accompanied by the sudden expansion of active aurora and westward electrojet to the evening side. Simultaneously(with an accuracy of 30-60 s) in midday-evening sector at L=4-5 the eastward electrojet is sharply intensificated, center of electrojet moves to the equator and the excitation of 0, 2-1, 5 Hz hydromagnetic emissions with continuous or discrete growth of oscillation frequency are occurred.

OBS

hydromagnetic emission: term usually used in the plural (hydromagnetic emissions).

Key term(s)
  • hydromagnetic emissions

Record 7 1986-12-16

English

Subject field(s)
  • Aircraft Piloting and Navigation
CONT

As the aircraft descends through heights of 45 m to 22. 5 m above the runway... the pilot becomes more aware of the expanding runway scene as visual cues are observed to move rapidly outward from the center of expansion. This is due to the speed of the "flowing visual field" increasing at a rate inversely proportional to the distance of the pilot.

French

Domaine(s)
  • Pilotage et navigation aérienne
CONT

Alors que l'avion descend en passant à des hauteurs variant de 45 m à 22,5 m au-dessus de la piste (...), le pilote devient plus conscient de la position relative de la piste et il voit les repères visuels se déplacer rapidement à partir du point de fuite vers l'extérieur. Cette impression est due au fait que la vitesse du "champ visuel flottant" augmente en raison inverse de l'éloignement du pilote.

Record 8 1986-10-15

English

Subject field(s)
  • Air Navigation Aids
  • Aircraft Piloting and Navigation
CONT

Ordinarily in speaking of perceived motion, reference is made to the "movement of an object". In dealing with a pilot's use of visual aids, however, it is apparent that what is involved is the "movement of the observer" which is accompanied by expansion of the visual scene as the pilot directs his aircraft toward the runway. The point towards which the flight path is directed is the center of expansion-the point where visual cues are motionless.

Key term(s)
  • centre of expansion

French

Domaine(s)
  • Aides à la navigation aérienne
  • Pilotage et navigation aérienne
CONT

Généralement, lorsque l'on parle de mouvements perçus, il est fait mention du "mouvement d'un objet". Cependant, lorsqu'il s'agit de l'utilisation des aides visuelles par un pilote, il est évident que le mouvement en cause est le "mouvement de l'observateur" qui est accompagné de l'élargissement du champ visuel à mesure que le pilote se rapproche de la piste. Le point vers lequel est orientée la trajectoire de vol est le point de fuite, c'est-à-dire le point où les repères visuels paraissent immobiles.
