2015 Lecture Notes of the Institute for Computer Sciences, Social Informatics and Telecommunications Engineering  
Mutimodality appears in the modelling of rainfall drop size distributions (DSDs), and the understanding of the distribution in general is important as it helps in the predicting and mitigation of attenuation  ...  This work looks at the occurrence of multimodality in the rainfall DSDs in southern England, with data captured at the Chilbolton Observatory for a seven year period (2003 to 2009).  ...  in the Rainfall Drop Size Distribution  ...

2010 Journal of Hydrology  
Examination of the rainfall distribution and flood response shows that the extent and the position of the karst terrain provided a major control on flood response in the region impacted by the storm.  ...  Unit peak discharges range from 5 to 7 m 3 s À1 km À2 in basins characterised by size up to approximately 25 km 2 .  ...  Bat provided valuable assistance in the interpretation of the flood response in the karst terrain.  ...

Late Pleistocene human population bottlenecks, volcanic winter, and differentiation of modern humans

If a population has been of relatively constant size for a very long time, then its mismatch distribution tends to be multimodal or ragged (Harpending et al., 1993) .  ...  sediments exposed by a drop in sea level.  ...  Pairwise distributions were generated from a sample of 50 individuals in each subpopulation, so MPW for each iteration is calculated on a sample of pairwise comparisons between 150 individuals.  ...
