[When] using exponential smoothing models for forecasting, it is very important to know the salient characteristics of the time series...(i. e. trend and seasonality among other characteristics) before [choosing an] exponential smoother. The better the diagnosis of the salient characteristics of the time series, the more accurate the exponential smoothing forecasts are likely to be. 3, record 1, English, - exponential%20smoothing%20forecast

Pole-zero cancellation(Tail cancellation) … we approximated the preamp output pulse as a step function, however, in a real preamp pulse, the falling tail is a long exponential decay instead of a simple step function. Consequently, there is a small amplitude undershoot starting at about 7τ. This undershoot decays back to baseline with the long time constant of the preamplifier. At medium to high counting rates, a substantial fraction of the amplifier output pulses will ride on the undershoot from a previous pulse. The apparent pulse amplitudes measured for these pulses will be significantly lower, which deteriorates the energy resolution. Most shaping amplifiers incorporate a pole-zero cancellation circuit to eliminate this undershoot. The benefit of pole-zero cancellation is improved peak shapes and resolution in the energy spectrum at high counting rates. 1, record 6, English, - %20pole%2Dzero%20cancellation%20circuit

Au lieu de partir de la ligne de base, un signal va donc débuter sur la queue d’un signal précédent, c’est-à-dire sur une valeur légèrement négative. Son amplitude mesurée par rapport à la ligne de base est un peu trop faible et cela va se traduire par un élargissement des pics du côté des basses énergies. 1, record 6, French, - circuit%20de%20compensation%20du%20passage%20%C3%A0%20z%C3%A9ro

Columns can be operated in an expanded bed form at higher flow rates, so preventing fouling and compression and improving mass transfer. Alternatively packed biocatalyst particles can be used in a trickle-flow mode as in some waste-water processes employing microbial flocs.... Packed columns allow a high concentration of biocatalyst to be used. The product molecules or other inhibitors produced during the reaction are constantly swept out of the reactor so that the concentration of products are minimized-so less product inhibition occurs.... The decay of enzyme columns packed with immobilized enzyme or immobilized microbial cells generally proceeds in an exponential pattern related to operating time. 2, record 7, English, - enzyme%20column

Dans un premier type de réacteur, les enzymes insolubilisées, attachées à des particules, sont brassées dans le substrat. Cette technologie primitive, utilisée dans les industries agro-alimentaires, est simplement dérivée de celles utilisées pour les enzymes solubles. La récupération de l'enzyme insoluble reste délicate et s'opère au prix de grandes pertes. Aussi cette technique est-elle peu utilisée. Les autres types de réacteurs reposent sur le passage lent du substrat, à une vitesse déterminée par l'expérience, au travers d'une colonne d'enzyme immobilisée. Essentiellement, le produit de réaction circule X fois à travers la même colonne, jusqu'à l'obtention du rendement adéquat.

Les problèmes de classe NP (c'est-à-dire non résolubles en temps polynomial) ont la propriété fondamentale suivante : bien qu'il soit facile de vérifier si une valeur donnée est solution, il est très difficile de les résoudre sans information complémentaire. Quand la «taille» n d'un problème NP augmente, le nombre d'étapes de calcul, et donc le temps requis pour vérifier une solution, croît comme une fonction polynomiale de n, telle [le carré de n] (...); toutes les méthodes connues pour trouver une solution exigent un temps de calcul croissant en fonction de n, beaucoup plus rapidement que toute fonction polynôme; ce temps de calcul croît généralement comme une fonction exponentielle (...) 1, record 13, French, - probl%C3%A8me%20NP
