Data Set Used
In Geoscience domain, large amounts of data are accessible, however they vary in formats and are stored at various organizations leading to problems of data discovery, data interoperability and usability. In this paper, we propose a new semantic metadata paradigm based on ontologies and the use of Semantic Web languages. Our suggested data model ontology is… (More)
The objectives of this research are (1) to parallelize a suite of multiregion groundwater flow and solute transport codes that use Galerkin and Lagrangian-Eulerian finite element methods, (2) to test the compatibility of a global shared memory emulation software with a High Performance FORTRAN (HPF) compiler, and (3) to obtain performance characteristics… (More)
Multiple factors may affect the scale-up of laboratory multi-tracer injection into structured porous media to the field. Under transient flow conditions and with multiscale heterogeneities in the field, previous attempts to scale-up laboratory experiments have not answered definitely the questions about the governing mechanisms and the spatial extent of the… (More)
A simple genetic algorithm (SGA) was implemented on a cluster of Linux PCs to search for the most likely fracture networks in a soil column. The objective is to evaluate the performance of SGAs in a distributed computing environment that is widely and inexpensively available to environmental researchers and engineers. The Beowulf computer was built out of… (More)
A high performance computer model of coupled hydrogeological and biogeochemical processes. a practical map-analysis tool for corridor detection .
The complexity and diversity of knowledge and terminology within environmental sciences and engineering is one of the key obstacles for successful interdisciplinary studies. Relevant data is difficult to locate and retrieve primarily due to varying formats, schemas and semantics. For example, for a typical modeling assignment a researcher needs to acquire… (More)
