Fixation in Evolutionary Games under Non-Vanishing Selection
Non-Vanishing Selection evolutionary game
2010/4/7
One of the most striking effect of fluctuations in evolutionary game theory is the possibility for mutants to fixate (take over) an entire population. Here, we formulate a WKB (Wentzel-Kramers-Brillou...

Order Selection AR Models Hydrologic Time Series
2009/10/28
Recently several criteria have been proposed for selection of orders of AR
models. One of these. namely the AIC has been used in hydrologic analysis.
However, the results given by these criteria whe...

Models are widely used to assist water managers in their duties, yet there is little advice to help water managers select a model appropriate to their particular application. The advice that is availa...
Root selection methods in flood analysis
unit hydrograph identification methods z-transform
2009/3/12
In the 1970s, de Laine developed a root-matching procedure for estimating unit hydrograph ordinates from estimates of the fast component of the total runoff from multiple storms. Later, Turner produce...
