FUNCTIONAL STANDARD [51 records]

Record 1 2026-01-08

English

Subject field(s)
  • Language (General)
  • Artificial Intelligence
CONT

In opposition to Chomsky, who(as I noted) pays little attention to how his derivations might be realized by an individual speaker operating under "real-world" constraints, Bresnan and her colleagues have fashioned a perspective designed to illuminate how an individual will perceive or produce language. In her lexical-functional theory, there is no transformational component. The information traditionally embedded in the syntactic components is now placed in the individual' s lexicon-one's knowledge of specific words. Lexical-functional grammar provides each sentence with two structures : a constituent structure, which is similar to a surface structure(or phrase-marker tree) in the standard theory of Chomsky; and a functional structure, which includes all the grammatical relations relevant to the semantic interpretation of the sentence. The functional structure is generated by annotated phrase-structure rules working in conjunction with lexical entries for the various morphemes in a sentence.

English

Subject field(s)
  • Sociology of persons with a disability
CONT

A standard medical approach, indeed a common lay-person's approach, to thinking about disability involves viewing it as a problem that exists in a person's body. As a consequence, that individual is thought to require treatment or care to fix the disability, to approximate normal functioning, or perhaps as a last measure, to help the individual adapt and learn to function despite the disability. So construed, disability is primarily an individual' s medical problem in need of treatment.... this medical model of disability holds that "a person's functional limitations(impairments) are the root cause of any disadvantages experienced and these disadvantages can therefore only be rectified by treatment or cure. "

French

Domaine(s)
  • Sociologie des personnes handicapées
CONT

Pour le modèle médical du handicap, [...] «le handicap est le problème d'individus désavantagés par leur état biomédical. Selon le modèle médical, les désavantages sont vus comme les résultats naturels et inévitables de simples faits biomédicaux.»

While the concept of disruptive coloration has been standard textbook material... with applications ranging from military uniforms and equipment to art..., empirical verification of the functional mechanism underlying disruptive coloration has remained elusive for two main reasons. First, disruptive coloration invariably occurs in conjunction with background matching, so disentangling their individual contributions to camouflage is therefore challenging... Second, disruptive coloration is best defined in terms of its function(impairing recognition) rather than its appearance...

As such, the soft perimeter may use standard traffic control devices in conjunction with law enforcement support to control access.

Enzymes immobilized on inorganic supports by covalent attachment show unique pH optimums, thermal profiles and kinetics.

Silanes such as this react with any available oxide or hydroxide groups on the surface of glass, ceramics or metal oxides.... Once an alkylamine group has been attached to the inorganic support it takes only standard organic coupling reactions to covalently bond the protein of interest.

You are likely to find it difficult to interpret the clinical importance of an effect size(if the weighted average effect is one-half of a standard deviation, is this effect clinically trivial, or is it large?). Once again, you should look for a presentation of the results that conveys their pratical importance(for example by translating the summary effect size back into natural units [3715]). For instance, if clinicians have become familiar with the significance of differences in walk test scores in patients with chronic lung disease, the effect size of a treatment on a number of mesures of functional status(such as the walk test and stair climbing) can be converted back into differences in walk test scores.

Record 43 1995-11-22

English

Subject field(s)
  • Engineering Tests and Reliability
DEF

Risk of the EUC and its control system (providing it is not a designated safety-related system) and associated human factor issues.

OBS

The main purpose of determining the EUC risk is to establish a reference point for the risk without taking into account safety-related systems and external risk reduction facilities.

Record 44 1995-11-22

English

Subject field(s)
  • Engineering Tests and Reliability
DEF

A protection system designed to respond to conditions on the EUC, which may be hazardous in themselves, or if no action were taken, could give rise to hazardous events, and to generate the correct outputs to mitigate the hazardous consequences or prevent the hazardous events.

OBS

In many cases the correct response of the protection system would be to bring all processes or movements to a predetermined safe state; in others the correct response may be more complex e.g. involving an ordered shutdown or start-up of equipment. The correct response may depend on the state of the EUC.

English

Subject field(s)
  • Engineering Tests and Reliability
DEF

Hardware failure which, in a single channel configuration, puts the safety-related system in a dangerous or fail-to-function state.

OBS

In systems with redundant channels, a dangerous hardware failure may not result in a dangerous or fail-to-function failure of the safety-related system.

The target dangerous mode failure measure for the safety integrity requirements of the safety functions to be implemented by the safety-related systems.

OBS

The target failure measure for safety-related systems are the demand mode of operation and the continuous/high demand mode of operation.

Record 50 1993-02-16

English

Subject field(s)
  • Immunology
DEF

A functional assay of total complement activity that measures the capacity of serial dilutions of serum to lyse a standard preparation of sheep red blood cells coated with antisheep erythrocyte antibody. The reciprocal of the dilution of serum that lyses 50 per cent of the erythrocytes is reported as the whole complement titer in CH50 units per milliliter of serum.

French

Domaine(s)
  • Immunologie
CONT

Dosage du complément hémolytique total. La zone finale d'hémolyse (hémolyse 100%) est difficile à déterminer. Aussi préfère-t-on se servir de l'hémolyse 50 %. Le tube où est reconnue l'hémolyse 50 % contient par définition "une unité de complément hémolytique 50 %" (1 unité CH 50). Par un calcul simple de dilution, on exprime le résultat du dosage fonctionnel en nombre d'unités CH 50 contenues dans un millilitre du milieu biologique étudié (unités CH 50/ml). Un seul tube est nécessaire dans le dosage du complément par temps d'hémolyse 50%.

English

Subject field(s)
  • Mechanical Transmission Systems
OBS

Document detailing the materials, functional performance and standard of a piece of equipment or complete system or installation to meet the performance specification. The document will contain sufficient details to enable the manufacturer to select and determine the material and components necessary to fulfil the requirements of the customer, and conversely to allow the customer to determine whether the products offered are to his satisfaction.

French

Domaine(s)
  • Transmissions mécaniques
OBS

Document donnant les caractéristiques de fonctionnement détaillées, les matériaux et les normes relatives à tout ou partie de l'installation dans le but d'obtenir les caractéristiques, les prescriptions. Le document sera suffisamment détaillé pour permettre au constructeur de choisir et de déterminer le matériel et les appareils pouvant remplir les prescriptions du client et en contrepartie, pour permettre au client de déterminer si le produit qui lui est offert peut convenir.
