English

Subject field(s)
  • String Instruments
CONT

The sarod is a short-necked, fretless plucked lute from North India... The sarod has a wooden body, usually made of teak, with a parchment sound table, and a small secondary resonator at the top of the neck. An unusual feature of the sarod is that the neck is covered with a sheet of smooth, polished metal. As there are no frets on the sarod, the subtle pitch inflections central to Indian music are achieved by sliding the finger on the string as it is pressed down on the metal surface. Typically, the sarod has four or five main playing strings, three to five drone and "chikari" strings and up to 16 sympathetic strings. The strings are plucked with a plectrum, which is usually made of coconut shell.

The quotient of the pitch at the reference surface, expressed in millimetres, divided by [pi].

CONT

Module (inch) is the ratio of the pitch diameter in inches to the number of teeth. It is the reciprocal of the diametral pitch. Module (millimeter) is the ratio of the pitch diameter in millimeters to the number of teeth. It is converted to diametral pitch by the equation: Pd = 25.4/module (millimeters).

OBS

Module may be in either inch or millimetre units. In inch units module is the reciprocal of the diametral pitch.

English

Subject field(s)
  • Aircraft Airframe
  • Aircraft Maneuvers
OBS

... in order to trim an elevator to hold the nose down, the elevator's trim tab will actually rise up into the slipstream. The increased pressure on top of the trim tab surface caused by raising it will then deflect the entire elevator slab down slightly, causing the tail to rise and the aircraft's nose to move down. In the case of an aircraft where deployment of high-lift devices(flaps) would significantly alter the longitudinal trim, a supplementary trim tab is arranged to simultaneously deploy with the flaps so that pitch attitude is not markedly changed.

OBS

elevator trim tab: term standardized by ISO.

English

Subject field(s)
  • Remote Sensing
CONT

Preprocessing is an important and diverse set of image preparation programs that act to offset problems with the band data and recalculate DN [Digital Number] values that minimize these problems. Among the programs that optimize these values are atmospheric correction(affecting the DNs of surface materials because of radiance from the atmosphere itself, involving attenuation and scattering) ;Sun illumination geometry; surface-induced geometric distortions; spacecraft velocity and attitude variations(roll, pitch, and yaw) ;effects of Earth rotation, elevation, curvature(including skew effects), abnormalities of instrument performance(irregularities of detector response and scan mode such as variations in mirror oscillations) ;loss of specific scan lines(requires destriping), and others. Once performed on the raw data, these adjustments require appropriate radiometric and geometric corrections.

OBS

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

La première étape de prétraitement des données SAR correspond à la transformation des données 16 bits en données 8 bits et ce, afin de faciliter la manipulation ainsi que la combinaison avec les autres données optiques qui sont, généralement, sur 8 bits. La deuxième étape consiste à réduire le châtoiement inhérent aux images SAR [radar à synthèse d'ouverture] [...] La troisième étape comprend le prétraitement des données TM [Thematic Mapper] de Lansat dont le but vise essentiellement l'amélioration de la qualité des images. Cette étape est effectuée en trois phases : la superposition géométrique, le géocodage des images optiques comparées à une image SAR disponible de type GEC [Geocoded Ellipsoid Corrected] et, enfin, le rééchantillonnage des pixels à une résolution de 25 m.

Subject field(s)
  • Aircraft Propulsion Systems
CONT

The X-wing has emerged from the circulation controlled rotor(CCR) in which a hollow blade of roughly oval aerofoil section, that is, without a real lifting profile at all, can be made to lift effectively by blowing a layer of air through a slot and across the curved Coanda surface which forms the trailing-edge. While this in itself produces lift, the air jet can be so modulated as the rotor turns that it has the same effect as the cyclic pitch changing of the normal rotor. Finally, a further jet can be blown through a second slot near the leading-edge of the blade so that it restores the lost lift of the retreating blade. This fore-and-aft blowing is the key to the stopped-rotor X-wing.
