THRESHOLD PERFORMANCE [7 records]

Record 1 2022-03-10

English

Subject field(s)
  • Environmental Studies and Analyses
  • Air Pollution
CONT

Other methods can also be applied to determine the value of the concentration threshold such as referring to the performance of specific statistical models. More population-based studies in various regions using their specific air pollution threshold are recommended, and future studies are required to further explore the determination of the concentration threshold of air pollution.

Record 2 2014-06-10

English

Subject field(s)
  • General Scientific and Technical Vocabulary
CONT

An enabling technology is one that makes another technology possible. Some powerful technologies spring into existence when they do because some kind of price or performance threshold has been crossed by one or several enabling technologies.

CONT

[An interdisciplinary research team at the Beckman Institute] has created several powerful acoustic signal-processing algorithms which confer marked improvements in hearing speech sound in real world situations, as well as a low power wireless communication technology (an important enabling technology for hearing aids).

French

Domaine(s)
  • Vocabulaire technique et scientifique général
DEF

Technologie qui permet l'existence d'une autre technologie, qui constitue un élément catalyseur pour beaucoup d'autres technologies.

CONT

Le tube à vide fut la technologie catalyse à la fois pour la radio et pour la télévision; tout comme le moteur à vapeur le fut pour les locomotives et les dynamos électriques.

OBS

technologie mobilisatrice : proposé dans La Presse du 23 août 1990.

OBS

technologie habilitante : employée dans le programme de construction de la BCTEL (Division Telecom 90-21).

Spanish

Campo(s) temático(s)
  • Vocabulario técnico y científico general
CONT

[...] otras tecnologías habilitantes, que corresponden a aquellas que, por si solas, no permiten resolver o simplificar un proceso de negocio; pero que al aplicarlas en conjunto con un rediseño de procesos y, en la mayoría de los casos, de otras tecnologías pueden efectivamente resolver estos procesos de negocios de una manera creativa y eficiente.

CONT

Al ser una tecnología básica, los navegadores, por sí mismos, no suponen una auténtica ayuda a la GC [gestión del conocimiento], sino más bien son una técnica habilitadora sobre la cual se construyen otras tecnologías, como las intranets, el correo electrónico o el chat.

English

Subject field(s)
  • Education Theory and Methods
CONT

Self-informing systems have information within the systems’ databases that will determine if interventions are necessary... A self-informing system would monitor student grade performance and identify all students whose GPA [grade point average] fell by more than an established threshold limit...

Record 4 2002-01-24

English

Subject field(s)
  • Radio Transmission and Reception
  • Telecommunications Transmission
DEF

The point at which the output S/N begins to fall faster than the input carrier-to-noise ratio (more precisely, it is where a 1 dB deviation between a straight line relationship between input C/N output S/N occurs).

OBS

Threshold performance is important where the satellite EIRP is weak, because it may allow the use of smaller antennas.

French

Domaine(s)
  • Émission et réception radio
  • Transmission (Télécommunications)

Spanish

Campo(s) temático(s)
  • Radiotransmisión y radiorrecepción
  • Transmisión (Telecomunicaciones)
DEF

Punto en el que la relación señal/ruido de salida comienza a caer más rápido que la relación portadora/ruido de entrada (más concretamente, esto sucede en el punto donde se produce una desviación de 1 dB entre una relación en línea recta entre la relación portadora/ruido de entrada y la relación señal/ruido de salida).

OBS

El comportamiento del umbral es importante cuando la potencia isótropa radiada equivalente (PIRE) del satélite es débil, porque puede permitir el uso de antenas más pequeñas.

Record 5 1994-02-11

English

Subject field(s)
  • Driving (Road Vehicles)
CONT

The two-day sessions include one-on-one professional evaluation of driving skills, classroom instructions, driving in urban and rural settings and practice of advanced vehicle performance manoeuvers like threshold braking, the latest collision avoidance techniques and the testing of vehicle performance limits.

French

Domaine(s)
  • Conduite automobile
DEF

Le freinage au seuil consiste à appuyer sur la pédale de frein jusqu'au point précédant le blocage des roues. Le principe est donc de ralentir la rotation des roues au maximum, mais graduellement, sans qu'elles glissent.

OBS

L'équivalent français est tiré d'un ouvrage, fourni par un terminologue de la GRC, dont le titre est : Techniques de conduite avancée par Denis Corriveau.

Record 6 1992-10-17

English

Subject field(s)
  • Artificial Intelligence
DEF

One of the early and fundamental modifications of the basic neural element proposed by Widrow. The Adaline has provisions for independent adjustment of each of the weights on the input to the threshold sections. Thus, based on the assessment of the network's performance, these parameters can be adjusted.

CONT

The Adaline takes the input and the desired output, and adjusts itself so that it can perform the desired transformation. Furthermore, if the signal characteristics change, the Adaline can adapt automatically.

OBS

The term Adaline is an acronym; however, its meaning has changed somewhat over the years. Initially called the ADAptive Linear Neuron, it became the ADAptive LINear Element, when neural networks fell out of favor in the late 1960s.

French

Domaine(s)
  • Intelligence artificielle
CONT

On considère les premiers réseaux de neurones (adaline de Widrow, perceptron de Rosenblatt).

CONT

Widrow conçut la machine Adaline qui fut utilisée pour la reconnaissance de la parole.

English

Subject field(s)
  • Aeroindustry
CONT

By contrast, the performance of an FM system deteriorates rapidly after falling below a certain threshold. Phase-modulated signals, when properly processed, require less bandwidth and can be coded using pseudo-noise and spread-spectrum techniques, thus reducing the chance of enemy detection.

French

Domaine(s)
  • Constructions aéronautiques
CONT

Les ingénieurs de Hughes ont découvert qu'avec cette méthode l'image de télévision s'affaiblit graduellement à mesure qu'augmente l'intensité du signal de brouillage, alors que les performances d'un système utilisant la technique FM se dégradent rapidement lorsqu'elles sont tombées au-dessous d'un certain seuil. Les signaux modulés en phase, lorsqu'ils sont convenablement traités, exigent une moins grande largeur de bande et peuvent être codés au moyen des techniques de pseudo-bruit et d'étalement de spectre, ce qui diminue les risques de détection par l'ennemi.
