Record 1 2017-05-11

English

Subject field(s)
  • The Eye

Record 2 2007-01-31

English

Subject field(s)
  • Space Physics
CONT

If the entropy is close to 0, the alpha angle provides the nature or type of the dominant scattering mechanism for that resolution cell. For example, it will idfentify if the scattering is volume, surface or double bounce.

OBS

alpha angle: term officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).

French

Domaine(s)
  • Physique spatiale
DEF

Angle qui permet d'identifier, pour une cellule de résolution donnée, les mécanismes de diffusion dominants (diffusion volumique, surfacique ou à double rebond), lorsque l'entropie avoisine le zéro.

OBS

angle alpha : terme uniformisé par le Groupe de travail de la terminologie de RADARSAT-2 (GTTR).

Record 3 2000-08-29

English

Subject field(s)
  • Welding and Soldering (Metals)
CONT

Three new geometries are developed: the semi-structure specimen (SESE alpha), the semi-structure specimen with torsion (SESE alpha T) and the Double Disc (DD) specimen. By varying the opening angle alpha of the semi-structure specimen, the influence of an increasing peel force on the (shear) fatigue resistance of a spot weld can be studied.

Record 5 1993-12-02

English

Subject field(s)
  • Operations (Air Forces)
  • Flight Instruments and Equipment (Aeroindustry)
  • Types of Aircraft
CONT

The highest alpha explored so far reached 32 degrees.

French

Domaine(s)
  • Opérations (Forces aériennes)
  • Instruments et équipement de bord (Constructions aéronautiques)
  • Types d'aéronefs
CONT

Les entrées d'air sont fixes mais elles ont jusqu'à présent tenu leurs promesses aux forts angles d'attaque jusqu'à Mach 1,9 (l'incidence maximale - alpha atteinte à ce jour en essais est de 32).

OBS

En aérodynamique, on désigne l'angle d'incidence par le signe grec «alpha».
