A global optimisation approach for parameter estimation of a mixture of double Pareto lognormal and lognormal distributions
(PERGAMON-ELSEVIER SCIENCE LTD, 2013-10-30)
The double Pareto Lognormal(dPlN) statistical distribution, defined interms of both an exponentiated skewed Laplace distribution and alog normal distribution, has proven suitable for fitting heavy tailed data. In this ...

Modelling soil organic carbon stocks in global change scenarios: a CarboSOIL application
(Copernicus, 2013)
Global climate change, as a consequence of the increasing levels of atmospheric CO2 concentration, may significantly affect both soil organic C storage and soil capacity for C sequestration. CarboSOIL is an empirical model ...

Solving the median problem with continuous demand on a network
(Springer, 2013-12)
Where to locate one or several facilities on a network so as to minimize the expected users-closest facility transportation cost is a problem well studied in the OR literature under the name of median problem. In the median ...

Variable neighborhood search for minimum sum-of-squares clustering on networks
(ELSEVIER SCIENCE BV, 2013-10-13)
Euclidean Minimum Sum-of-Squares Clustering amounts to finding p prototypes by minimizing the sum of the squared Euclidean distances from a set of points to their closest prototype. In recent years related clustering ...

Locating a semi-obnoxious covering facility with repelling polygonal regions
(ELSEVIER SCIENCE BV, 2013-11-01)
A facility is to be located in the Euclidean plane to serve certain sites by covering them closely. Simultaneously, a set of polygonal areas must be protected from the negative effects from that facility. The problem is ...
