UNSAMPLED [5 records]

Record 1 2021-10-26

English

Subject field(s)
  • Modelling (Mathematics)
  • Commercial Fishing
CONT

Spatio-temporal models estimate the degree of information-sharing between neighboring points by estimating the shape of the covariance function from a specified family, which then allows the model to incorporate either strong or weak smoothing for predictions that are close in space and time. This can improve estimates for locations and times with low sample size, including for unsampled strata.

English

Subject field(s)
  • Metrology and Units of Measure
  • Commercial Fishing
CONT

While the... catchability coefficient from the population model in principle corrects for this unsampled inshore proportion of the stock, its value is poorly informed with the available data and reflects the prior assumption of its value.

French

Domaine(s)
  • Unités de mesure et métrologie
  • Pêche commerciale
DEF

Fraction de la biomasse qui est capturée par unité d’effort de pêche.

CONT

Si le coefficient de capturabilité du relevé [...] tiré du modèle de population corrige en principe cette proposition côtière non échantillonnée du stock, sa valeur est difficile à établir à l'aide des données disponibles et reflète la valeur précédemment présumée.

Materials Used in PEP [Performance Evaluation Program] Laboratory... blank filters are used... Lot blanks, representing a new lot or shipment of filters, are unconditioned, unsampled filters used to determine if effects on filter weight stability have occurred due to the volatilization of material from the filter or to the absorption of gaseous material into the filter from the atmosphere.

Subject field(s)
  • Remote Sensing
DEF

The smallest usable element of an image.

CONT

For applications such as cartography, where it is important to precisely locate the correct position of features such as roads and boundaries, it has been difficult or impossible to evaluate the relative performance of different sensors through the standard specifications of IFOV [Instantaneous Field of View] or spatial resolution. In an effort to overcome this difficulty, a second concept... labeled spatial effective resolution element(SERE), is evolving. Although this concept is not fully developed, it provides an indication of the factors to be taken into account when attempting to correlate different systems. These factors include : surface area on the Earth, or its equivalent on the image plane, the IFOV and the spread function resulting from optical diffraction and aberrations as well as electronic lag or smear. Essentially, the concept of SERE is an attempt to determine the IFOV of the hypothetical, unsampled(ideal) scanning system which would yield performance equivalent to that of any given real sensor system. Whether such an equivalence exists is yet to be determined.
