Record 1 2021-06-23

English

Subject field(s)
  • Space Exploration Equipment and Tools
CONT

Supersonic parachutes have been used as aerodynamic decelerators during entry and decent into low-density atmospheres, [for instance in] Mars space exploration missions.

Record 2 2020-10-14

English

Subject field(s)
  • Mathematics
  • Artificial Intelligence
CONT

[The goal of] constraint propagation is... to reduce the search space of a problem instance through the repeated analysis and evaluation of variables, their domains, and the interdependence between the variables that is induced by the set of constraints.

French

Domaine(s)
  • Mathématiques
  • Intelligence artificielle
CONT

[...] la propagation de contraintes [...] permet [...] de réduire l'espace de recherche.

Spanish

Campo(s) temático(s)
  • Matemáticas
  • Inteligencia artificial
CONT

El algoritmo de propagación de restricciones en principio es muy directo; cuando se modifica el dominio de una variable de decisión, se examinan las restricciones que contienen dicha variable para determinar si algunos valores en los dominios de otras variables de decisión ahora son incoherentes.

Record 3 2017-12-01

English

Subject field(s)
  • Theoretical Astronomy
  • Spacecraft
CONT

The argument of pericenter, for example, is defined as follows. There is a line through space which is fixed by convention as a reference. If one body orbits another(for instance the Moon orbiting around the Earth) the argument of pericenter associated with this orbit is the angle in the plane of the orbit between the reference line and the closest point of the orbit to the focus. The angle described above is measured from the focus of the orbit and in the direction which the object orbits.

French

Domaine(s)
  • Astronomie théorique
  • Engins spatiaux
DEF

Angle ayant pour sommet le centre de masse du corps principal et dont les côtés passent respectivement par le nœud ascendant et le périastre.

Record 4 2013-04-03

English

Subject field(s)
  • Passenger Service (Rail Transport)
CONT

ARNK field... In order for the computer to book a continuing flight in the itinerary, it must be advised how the passenger is arriving at the boarding point. For instance, if we were to input Toronto-Ottawa and then Montreal-Toronto, such an itinerary is illogical to the computer and will cause the response... In such cases we say that the leg of space is "ARNK" or Arrival Unknown. In order to advise the computer of this we input our own I field.

French

Domaine(s)
  • Trafic voyageurs (Transport par rail)
CONT

Zone itinéraire en surface (ARNK) [...] Pour qu'il puisse réserver des places sur un vol de correspondance, il doit savoir comment le passager se rendra au point d'embarquement. Par exemple, un message d'entrée indiquant un itinéraire constitué des tronçons Toronto-Ottawa et Montréal-Toronto seulement est illogique pour l'ordinateur, qui donnera la réponse-erreur suivante : [...] Dans de tels cas, on qualifie le tronçon de ARNK (Arrival Unknown) ou Arrivée inconnue et on l'indique à l'ordinateur en introduisant une zone I spéciale pour le transport en surface.

English

Subject field(s)
  • Artificial Intelligence
DEF

In machine learning, the set of all instances from an instance space that can be described in a given description language.

CONT

Different subsets of the instance space correspond to different concepts. Descriptions of those concepts are elements of the description space.

Record 8 2005-08-02

English

Subject field(s)
  • Flexography (Printing)
DEF

A process where color capability is measured and recorded.

CONT

For instance, on a printer, or printing press, strips of various CMYK [cyan, magenta, yellow, black] values are read with a measuring instrument. This information is saved into a file that can be used to define the color space of that printer or press. The same applies to monitors. Usually an emissive colorimeter is attached to the face of the monitor for calibration, and then to measure its color space, or color capability. This process of measuring a color space is called characterization...

OBS

Flexography has the potential to approach and rival the print quality of rivals lithography and gravure, if flexo converters are willing to pay the price. That price is awareness and control of printing variables. This type of control can be obtained with a press fingerprint -- or as it is more commonly called today, press characterization. Characterization, when done correctly, has the potential to control variability in the current process.

French

Domaine(s)
  • Flexographie (Imprimerie)
DEF

Technique de vérification des paramètres d'une presse en vue de la reproduction précise des couleurs primaires et de la quadrichromie à l'aide de méthodes densitométriques et d'analyse d'élargissement du point.

OBS

caractérisation de presse; programme des couleurs : Termes et définition tirés du Vocabulaire de la flexographie de France Brodeur. Reproduction autorisée par l'Institut des communications graphiques du Québec.

Record 9 2003-03-17

English

Subject field(s)
  • Scientific Instruments
  • Spacecraft
CONT

Fokker Space is Europe's leading solar array manufacturer for spacecraft. Its solar array release system, which employs the principle of cutting of an aramid hold-down cable by a thermal knife, has numerous advantages over, for instance, pyrotechnic devices. The tension in the cable decreases gradually, preventing shocks and because this system is insensitive to electro-magnetic disturbances the possibility of a spontaneous release is eliminated. The thermal knives can be used a number of times, allowing performance tests to be performed on actual flight hardware.

Key term(s)
  • thermal knives

French

Domaine(s)
  • Instruments scientifiques
  • Engins spatiaux
CONT

Les entreprises et les institutions des Pays-Bas [...] participent à plus de 20 projets technologiques, par exemple : couteau thermique pour les batteries de panneaux solaires, installations de simulation, microscopes pour la recherche en microgravité, dispositifs biologiques, filtres biologiques, capteurs, systèmes microtechnologiques et d'appui à l'équipage.
