Incorporating anthropogenic variables into a species distribution model to map gypsy moth risk.
Lippitt, Christopher D.; Rogan, John; Toledano, James; … - 2008
This paper presents a novel methodology for multi-scale and multi-type spatial data integration in support of insect pest risk/vulnerability assessment in the contiguous United States. Probability of gypsy moth (Lymantria dispar L.) establishment is used as a case study. A neural network...

A robust methodology for prediction of trust and reputation values
Hussain, Farookh Khadeer; Chang, Elizabeth; Hussain, Omar - 2008
In this paper, we present the FC direct trust value-based decision making methodology, for making direct trust value based decisions regarding interactions in (a) a given context and during the current time slot, and (b) a given context and at a future time slot. The direct trust value-based...

Modelling of dynamic recrystallisation of 316L stainless steel using a systems approach
Abbod, MF; Mahfouf, M; Linkens, DA; Sellars, CM - 2007
Dynamic recrystallisation (DRX) is an important aspect for industrial applications in hot metal working. Although DRX has been known for more than thirty years, its mechanisms have never been precisely investigated, in part because it was not readily possible to make local texture measurements....

Applications of Point Processes in Empirical Economics and Finance
Kehrle, Kerstin - 2010
Standard statistical methods in the empirical economics and finance literature are mostly applicable to data that is aggregated on equally spaced time points. However, a key characteristic of many economic and financial variables is that they occur randomly and are observed irregularly in time....

Bayesian Learning in Sparse Graphical Factor Models via Variational Mean-Field Annealing
West, Mike - 2010
We describe a class of sparse latent factor models, called graphical factor models (GFMs), and relevant sparse learning algorithms for posterior mode estimation. Linear, Gaussian GFMs have sparse, orthogonal factor loadings matrices, that, in addition to sparsity of the implied covariance...
