back from control points at the lobe fronts the dates show considerable scatter. In part the scatter is thought to be due to a potential age range of 340100 yr in the organic layers. Linear and polynomialregressions were calculated for the time
and polynomial methods. However, the rates established by the two methods are quite similar. Because of this and other uncertainties it is difficult to draw inferences of climatic change from the changes in movement rate shown by the polynomial solution.
and global atmospheric temperatures) as indicators of global and regional climate, and standard statistical methods (ANOVA) and polynomialregression. Palaeoenvironmental data indicate that the regression model retrodicts (predicts the past) Holocene
An algorithm for integrating polynomials over any closed boundary and its application to calculation of volume under polynomial trend surfaces in Geomathematical and petrophysical studies in Sedimentology. An international Symposium.
In stratigraphical analysis polynomial trend surfaces may be used to approximate structural surfaces or intervals betwween these surfaces or other variables of interest. Using the derived algorithm it is possible to compute rapidly the exact volume
a three-dimensional reconstruction of the relief evolution from the Middle Miocene to the present. The modelling procedure is based on geostatistical recovery of the palaeosurfaces characteristic of each geomorphological evolution stage, using polynomial
Quadratic polynomialregression models were established for 5 pure tree (Pinus massoniana Lamb) plots between vegetation fractional coverage (VFC) and soil/water conservation effects (SCE/WCE) for 144 erosive rainfall events from 2007 to 2010
), Maximal Activity Level (MHR) and Solar radiation absorbed by a nude man (R’). The research applied the arithmetic mean, linear regression, polynomial function and frequency of occurrence of STI and PhS over specific ranges. - (BJ)
The application of third-order polynomials to define statistically the sediment cumulative frequency distributions for sample stations along the Rhode Island southshore illustrates a sedimentation pattern that follows the direction of longshore
After monthly and zonally averaged climatic data fields are represented by Legendre polynomials in latitude and Fourier series in time, it is seen that only a few terms are necessary to describe the gross features of the seasonal oscillation

A l'aide du modèle polynomial des retards échelonnés, les AA. différencient en fonction du temps les impacts agrégés des deux principaux modes d'investissement direct étranger aux Etats-Unis. Leur impact n'est pas uniforme et est spécifique du mode
and monthly sums and the multi-year trends were determined mathematically with the help of linear and polynomial trends of the 3rd and 6th degrees. The trends were compared with the long-interval tendencies for the basic factors controlling evaporation, i.e
