Functional mapping has been a powerful tool in mapping quantitative trait loci (QTL) underlying dynamic traits of agricultural or biomedical interest. In functional mapping, multivariate normality is often assumed for the underlying data distribution, partially due to the ease of parameter estimation. The normality assumption however could be easily violated in real applications due to various ...

In this paper we show some strange features of multidimensional data and their influence on classification. We introduce the probability distribution mapping function, and the distribution density mapping function which maps probability density distribution of points in n-dimensional space to a similar distribution in one-dimensional space of distances. The power approximation of the probabilit...

In this contribution, we present a discussion of some architectural ideas pertaining to the mapping distribution protocol. The efficiency of this protocol in terms of response time and the volume of traffic load it generates are important considerations. We consider how Egress Tunnel Routers (ETRs) can perform aggregation of end point ID (EID) address space belonging to their downstream deliver...
