Resumen

Preconditioning strategies based on incomplete LU factorization using thresholding with dual dropping (ILUT) are investigated for iterative solution of sparse linear systems arising in semiconductor dopant diffusion modelling. Of particular interest are questions associated with selection and adaption of threshold parameters with spatial resolution, timestep in the adaptive ODE integrator and the problem physics. We investigate these issues and carry out detailed numerical studies in one- and two-dimensions for a representative phosphorus diffusion model. Guidelines for optimally selecting the threshold parameters are deduced from the results, and strategies for adaptive parameter selection are presented.

Funding Information:
In this paper, we present a semantically-enabled search engine for EO products currently under development by the project Prod-Trees funded by the European Space Agency. The system uses semantic technologies to allow users to search for EO products in an application-oriented way using free-text keywords (as in search engines like Google), their own domain terms or both, in conjuction with the well-known interfaces already available for expert users. A specific innovation of the presented system is the use of a new standard called EO-netCDF, currently under development in Prod-Trees and expected to be submitted to OGC, for accessing EO products annotated with netCDF. netCDF is a well-known standard consisting of set of self-describing, machine-independent data formats and software libraries that support the creation, access, and sharing of array-oriented scientific data.4
