We consider a model of • floodplain evolving with channel •vulsion, deposition, •nd erosion. Avulsion is modeled as • r•ndom process in sp•ce and time. Sediment ransport is modeled by the diffusion equation (Culling's model). The power spectrum of v•ri•tions in the topographic profiles predicted by the model S(k) is proportional to k -2 (where k is the w•venumber). This is the Brown noise often...

We study the dependence of galaxy properties on the clustercentric radius and the environment attributed to the nearest neighbor galaxy using the Sloan Digital Sky Survey (SDSS) galaxies associated with the Abell galaxy clusters. We find that there exists a characteristic scale where the properties of galaxies suddenly start to depend on the clustercentric radius at fixed neighbor environment. ...

ISEA morphology index (M = E + D + S) was created in part to facilitate and automate morphology analysis, an essential aspect of our study, which otherwise would have required manual, visual screening of simulation images following changes to analogue implementation or parameterization. Conceptual parallels can be drawn between the morphology index and automated methods of classifying tumor his...
