Record 1 2015-09-30

English

Subject field(s)
  • Nuclear Plant Safety
DEF

A comprehensive and integrated assessment of the safety of the nuclear power plant that, by considering the initial plant state and the probability, progression, and consequences of equipment failures and operator response, derives numerical estimates of a consistent measure of the safety of the plant.

DEF

A formalism that allows one to combine propositions that have a measure of belief attached to them.

CONT

Probability theory has been used as the basis for combining numerical measures of uncertainty in several rule-based expert systems.

OBS

... modern probability theory has been developed axiomatically in which probability is an undefined concept much the same as "point" and "line" are undefined in geometry.

Record 3 2011-09-21

English

Subject field(s)
  • Calculating Procedures (Mathematics)
  • Nuclear Physics
CONT

Integral transport methods. The integral transport methods construct an expression for the angular flux at a given location by integrating over all external and scattering sources that could contribute, taking in account the probability of the source neutral reaching the given location without a collision. The collision probability method result from partitioning the domain of the problem into a large number of finite size regions and formulating the equation to calculate the average value of the neutral flux in each region. Like the Monte Carlo method, the result of collision probability method can be very accurate. This method has been successfully implemented for neutral propagating in 3D rectangular grids. Since the collision probability method is based on a global particle balance, the neutral flux at a given region is coupled to the neutral scalar flux of any other regions via collision probabilities which must be calculated by multi-dimensional numerical integration involving expensive evaluation of Bickley functions.

French

Domaine(s)
  • Procédés de calcul (Mathématiques)
  • Physique nucléaire
CONT

Dans la méthode de résolution par probabilité de collision, on découpe l’espace en éléments de volumes Vi, que l’on va considérer comme homogènes, et l’on calcule les facteurs de probabilité de collision qui représentent la probabilité qu’un neutronémis dans le volume Vi subisse sa première interaction dans le volume Vj. On entend par neutron émis dans Vi tout neutron qui y a été créé ou dont les caractéristiques (énergie, direction) y ont été modifiées suite à une diffusion ou à une autre interaction.

Record 4 2011-08-17

English

Subject field(s)
  • Analytical Functions (Math.)
  • Surveying
  • Mathematical Geography
DEF

Any solution of the Laplace equation which has continuous derivatives of first and second order.

CONT

... it is quite natural to look at GSPD as a fractal measure ... with infinitely many types of singularities. Probing the surface with many random walks is equivalent to the estimation of the corresponding solutions of Laplace’s equation ... which are usually called harmonic functions. Consequently, the name harmonic measure is also used for GSPD.

OBS

To calculate the harmonic measure and its characteristic properties one can follow two numerical methods. i) After having generated a DLA cluster one releases further particles... whose diffusional motion is simulated by the same technique... which is used for growing the aggregate. These probe particles, however, are eliminated when they arrive at the surface, and a record is kept of how many times each of the surface sites is contacted in this way. The normalized number of contacts is then regarded as the growth probability.

Record 6 2007-02-21

English

Subject field(s)
  • Nuclear Plant Safety
DEF

An analysis using, for key parameters, single numerical values(taken to have probability of 1), leading to a single value of the result.

OBS

This safety analysis is performed under specific predetermined assumptions concerning the initial operational state and the initiating event, with specific sets of rules and acceptance criteria. Deterministic analysis can use either conservative or best estimate methods.

French

Domaine(s)
  • Sûreté des centrales nucléaires
DEF

Analyse utilisant, comme paramètres clés, des valeurs numériques uniques (retenues pour avoir une probabilité de 1), ce qui mène à une valeur unique comme résultat.

OBS

Cette analyse de sûreté est réalisée suivant certaines hypothèses prédéterminés concernant l'état opérationnel initial et l'événement initiateur, avec un ensemble de règles et de critères d'acceptation spécifiques. L'analyse déterministe peut être réalisée soit avec la méthode prudente ou la méthode de type réaliste.

Record 8 1999-04-08

English

Subject field(s)
  • Artificial Intelligence
DEF

A numerical weight given to a fact or relationship to indicate the confidence one has in the fact or relationship. These numbers behave differently than probability coefficients. Most rule-based systems use certainty factors rather than probabilities.

CONT

The number 800 appearing in the action of the sample rule is called a certainty factor. It indicates on a scale from - 1 to 1000 how certain the conclusion is, given that the premise is known to be true with certainty.

OBS

certainty factor, confidence factor: terms standardized by ISO/IEC and CSA.

French

Domaine(s)
  • Intelligence artificielle
DEF

Valeur attribuée à la validité d'un énoncé, tel qu'une hypothèse, une règle d'inférence ou la conclusion d'une inférence.

CONT

CONT

Dans les domaines où la connaissance n'est pas certaine on peut avoir intérêt à associer à chaque règle de production un coefficient de certitude et à chaque fait un coefficient de vraisemblance.

OBS
