Kernel smoothing is commonly used in spatial point patterns to construct intensity plots. Kernels allow for visually and subjectively inferring on first-order stationarity. Formal objective tests exist for testing first-order ...

In some standard applications of spatial point pattern analysis, window selection
for spatial point pattern data is complex. Often, the point pattern window is given a
priori. Otherwise, the region is chosen using some ...

The Discrete Pulse Transform (DPT) makes use of LULU
smoothing to decompose a signal into block pulses. The most recent and
effective implementation of the DPT is an algorithm called the Roadmaker's Pavage, which uses ...

BACKGROUND : Project success used to be measured solely in terms of efficiency metrics such
as scope, cost and time; however, there are proposals that more attention should be paid
to process-related performance factors ...

Forensic dentists are frequently required to determine the
age at death of unidentified skeletons, or to age live individuals
who have no record / documentation of their chronological
age. In order to be of the greatest ...

The LULU smoothers are effective nonlinear smoothers for signals. We investigate their ability to remove different noise types, namely symmetrical and skewed, as well as heavy- and light-tailed, thereby uncovering the true ...

Two spatial data sets are considered to be similar if they originate from the same stochastic process in terms of their spatial structure. Many tests have been developed over recent years to test the similarity of certain ...

We present a historical and theoretical overview of the more complicated and less used G/M and M/G
queueing processes, which allow for non-specific arrival and service time distributions. Such a model
provides a more ...
