Record 1 2020-12-22

English

Subject field(s)
  • Radar, Radio Guidance and Goniometry
  • Astronomy
CONT

An impulse response function and a transfer function of use for partially coherent systems are presented. Partially coherent systems are those that transform a complex amplitude input to an output intensity and are encountered in many guises including optical systems, radiometers, scatterometers, astronomical radars...

  • Astronomía
CONT

Los radares astronómicos son los más potentes, ya que los astros que han de reflejar sus ondas se encuentran a veces a centenares de millones de kilómetros […]

Record 2 2011-11-22

English

Subject field(s)
  • Non-Surgical Treatment
  • Muscles and Tendons
CONT

Neuromuscular electrical stimulation (NMES) is the application of electrical stimuli to a group of muscles, most often for the purpose of muscle rehabilitation.

CONT

Neuromuscular electrical stimulation is primarily used by physical therapists as a form of rehabilitation after injury, stroke, or other incident that results in loss of muscle function. NMES is achieved by passing an electrical impulse from a device through electrodes placed on the skin over the targeted muscle or muscles.

French

Domaine(s)
  • Traitements non chirurgicaux
  • Muscles et tendons
CONT

La stimulation électrique neuromusculaire, ou simplement «stimulation électrique» (SE), est une modalité utilisée essentiellement pour renforcer les muscles, sans l'objectif d'intégrer une tâche fonctionnelle comme avec la SEF [stimulation électrique fonctionnelle].

Spanish

Campo(s) temático(s)
  • Tratamiento sin cirugía
  • Músculos y tendones
DEF

Estimulación eléctrica de las neuronas motoras inferiores con el objetivo de lograr la contracción de músculos paréticos o paralizados [...], para mejorar el reaprendizaje motor.

English

Subject field(s)
  • Telecommunications
  • Optics
  • Electronics
DEF

A two-dimensional brightness pattern in an image, after processing, corresponding to the signal reflected by an object whose sigma falls within the dynamic range of the system, and for which the width of the imaged pattern is determined by the radar and processor rather than by the size of the object.

Key term(s)

CONT

réponse impulsionnelle à support infini.

Subject field(s)
  • Mathematics
  • Computer Graphics
OBS

See Dirac equation, Dirac function, Dirac operator, Dirac impulse.

French

Domaine(s)
  • Mathématiques
  • Infographie
CONT

Il résulte de la quantification [...] de l'espace et du temps que la dimension est elle-même quantifiée (E). Il suffit alors de convoluer [...] par un peigne de Dirac mais le développement de ce formalisme ne s'impose pas ici.

Record 6 2000-03-08

English

Subject field(s)
  • Nervous System
DEF

A complex of learning and behavioral disabilities seen primarily in children of near average to above average intelligence, exhibiting also deviations of function of the central nervous system. The impairment may involve perception, conceptualization, language, memory, and control of attention, impulse and motor function.

French

Domaine(s)
  • Système nerveux
CONT

L'instabilité ou agitation psychomotrice [...] peut être réelle, mais dans des cas limités, [...] l'agitation permanente de l'enfant répond à un dysfonctionnement cérébral à minima [...] La plupart des instabilités sont symptomatiques d'un malaise affectif important ou même mineur, et à certains moments elles ne sont que l'expression critique d'une phase évolutive normale, l'enfant libérant ainsi son trop-plein d'énergie.
