Spatial heterogeneity, social structure and disease dynamics of animal populations.
Social groupings, population dynamics and population movements of animals all give rise to spatio-temporal variations in population levels. These variations may be of crucial importance when considering the spread of infectious diseases since infection levels do not increase unless there is a sufficient pool of susceptible individuals. This paper explores the impact of social groupings on the p...
متن کاملModeling Spatial Dependence and Spatial Heterogeneity in County Yield Forecasting Models
The implications of ignoring potential spatial dependence in county-level yield data are discussed. Spatial dependence in a county-level yield data set is identified and methods for correcting the dependence via spatial weighting matrices and generalized least squares regression are performed. The paper also examines how the spatial dependence declines as the distance between observations incre...
متن کاملClustered Common Spatial Patterns
We propose to cluster class-wise covariance matrices in order to identify different groups of covariances contributing to the same condition. Each cluster represents a different brain pattern associated with one class. Further, we present Clustered Common Spatial Patterns, a new algorithm that applies this technique prior to CSP. We show that CCSP can outperform CSP in a binary imagery movement...
متن کاملHigher Compression from the Burrows-Wheeler Transform by Modified Sorting
We show that the ordering used in the sorting stage of the Burrows-Wheeler transform, an aspect hitherto ignored, can have a significant impact on the size of the compressed data. We present experimental results showing smaller compressed output achieved with two modifications to the sorting: using a better alphabet ordering and reflecting the sorted strings as in binary reflected Gray coding. ...
