  • The objective focuses on the sensitivity analysis of large agent-based modeling of spatial opinion exchange, accelerated using multiple graphics processing units (GPUs). It is conducted using a variance-based approach, requiring numerous model runs

  • slate rock surfaces in north Wales, UK using digital photography and an image analysis system (Image-J). Analysis of variance suggested no significant variation in RaGRs with vertical or horizontal location on the rock, thallus diameter, aspect, slope

  • longitudes (136-126° W), the teleconnections and NHTs explain over 50% of the regional ice edge variance. Increases in both NHTs and ice retreat since the mid-1990s account for the large explained variances observed in regression analyses extending

  • of the RUSLE C factor can explain some of the variance (4–5 fold). However, most of the variance is explained by problems with the K factor.

  • attributes explain the largest proportion of firm productivity variance.

  • Avec une part moyenne de variance expliquée de l'ordre de 60%, la couverture neigeuse observée en octobre sur les latitudes moyennes de l'Eurasie constitue un précieux prédicteur des principales caractéristiques climatiques de l'hiver suivant sur la

  • ) and dispersion parameters (differences in variance between treatments). They found that forest floors of harvested plots had lower phosphorus and potassium concentrations than control plots. It is highlighted that clear-cutting was not associated with strong soil

  • along widely spaced short transects. They describe the sampling, their means of spatial prediction using random forests plus regression kriging (RF + RK) from the sparse data and the non-parametric spatial bootstrap used to estimate the variances from

  • , moderate periods, and dry periods. For the humid periods, the total variance of soil moisture that could be explained by redundancy analysis was more consistent than those of the moderate and dry periods. For the humid periods on the first axis, soil

  • On se pose deux questions-clés concernant des données (ratio population-emploi) à l'échelle des comtés en Californie du Sud. On examine si cette région a connu ou va connaître une convergence dans la variance inter-comtés de ce ratio dans une

  • encroachment of both types of grassland. This factor explained 69% and 71% of the variance in models of dense and sparse grasslands, respectively. The observed changes in land cover indicated that land cover has become more homogeneous.

  • in the median and variance of several time-averaged and turbulent flow parameters were tested using non-parametric statistics. It is highlighted that observable differences in microtopography do not necessarily produce differences in interfacial hydraulics
