PROPAGATION ANALYSIS [8 records]

English

Subject field(s)
  • Mathematics

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.

  • Intelligence artificielle
CONT

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

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.

The virophage Sputnik is a satellite virus of the giant mimivirus and is the only satellite virus reported to date whose propagation adversely affects its host virus’ production. Genome sequence analysis showed that Sputnik has genes related to viruses infecting all three domains of life.

CONT

About 15 years ago, some staff at Canadian parks started classifying fractures as "pops"(sudden planar fractures), and "drops"(sudden collapses) due to collapse of a thick weak layer. A recent analysis showed that pops and drops were common near human-triggered avalanches, but other types of fractures were infrequent near such avalanches. This is likely because pops and drops indicate that slab and weak layer properties are favourable to fracture propagation...

CONT

The types of fractures include sudden planar, also known as "pop" because of the sound it makes, and "drop", or resistant planar.

CONT

Both these layers are critical weaknesses showing fast and clean shears (POPS or DROPS) in stability tests. [Example approved by the Avalanche Bulletin Terminology Standardization Committee.]

OBS

sudden planar fracture (pop, clean and fast fracture), SP: a thin planar fracture suddenly crosses column in one loading step AND the block slides easily on the weak layer. [Reference: Table on Fracture Character in Small-Column Snowpack Tests.]

OBS

Prof. Bruce Jamieson of the University of Calgary has come up with a code for identifying weak layers[: Fracture Character in Small-Column Snowpack Tests. Three major classes of fractures are identified: Sudden fractures (e.g.: pops and drops), Resistant fractures (e.g.: progressive compressions and resistant planars) and Breaks (e.g.: non-planar breaks).]

OBS

pop; sudden planar; sudden planar fracture: terms officially approved by the Avalanche Bulletin Terminology Standardization Committee.

CONT

Lors des tests de stabilité, ces deux couches fragiles présentent des ruptures par cisaillement nettes et rapides (ruptures soudaines et planes ou ruptures soudaines par effondrement). [Exemple entériné par le Comité d'uniformisation de la terminologie des bulletins d'avalanche.]

OBS

rupture soudaine et plane (rupture subite, nette et rapide), SP : La rupture est mince et plane. Elle se produit soudainement en une étape de surcharge sur toute la largeur de la colonne ET le bloc glisse facilement sur la couche fragile. [Référence : tableau sur les Caractéristiques de la rupture lors des tests de stabilité du manteau neigeux sur petite colonne.]

OBS

rupture soudaine et plane; rupture soudaine planaire : termes uniformisés par le Comité d'uniformisation de la terminologie des bulletins d'avalanche.

  • Occupation Names (General)

CONT

Forest biometrician.... Participate in a team oriented research project assessing the carbon dynamics of forest ecosystems at country to regional scales, including the effects of changes in land cover, land use, and land management. The current research focus is to quantify the carbon flux(either sink or source) from changes in land use and land cover for several major boreal, temperate, and tropical countries. The primary duties will be : 1) estimate errors and their propagation for all components of national-scale terrestrial C budgets; 2) design sampling strategies for data collection from field sites to remote sensing scenes; 3) perform statistical analysis of inventory data for estimating status and trend of forest biomass-carbon densities; 4) design a data management system, including quality control procedures, for keeping track of estimates of means and associated errors of carbon budget components that vary over time and space....

OBS

forest mensuration: The measurement of volume, growth and development of individual trees and stands, and the various products obtained from them.

The method of assumed states uses a piecewise linear approximation for complicated devices. The method requires assuming in which linear region a device is operating. EL has two possible states for diodes(on or off) and three states for transistors(active, cutoff, and saturated). Once a state is assumed, EL can use tractable linear expressions for the propagation analysis....
