The aim of the history matching method is to locate nonimplausible regions parameter space complex deterministic or stochastic models by model outputs with data. It does this via a series waves where at each wave an emulator fitted small number training samples. An implausibility measure defined which takes into account closeness simulated and observed as well uncertainty. As progress, becomes ...

Abstract The choice of a prior model can have large impact on the ability to assimilate data. In standard applications ensemble-based data assimilation, all realizations in initial ensemble are generated from same covariance matrix with implicit assumption that this is appropriate for problem. hierarchical approach, parameters function, example, variance, orientation anisotropy and ranges two p...

This paper considers a reconfigurable intelligent surface (RIS) aided orthogonal frequency division multiplexing (OFDM) relaying system, and investigates the joint design of RIS passive beamforming subcarrier matching under two cases, where Case-I ignores source-RIS-destination signal, while Case-II explores this signal for rate enhancement. We formulate mixed-integer nonlinear programming (MIN...

Ontology is the kernel technique of Semantic Web (SW), which models domain knowledge in a formal and machine-understandable way. To ensure different ontologies’ communications, cutting-edge technology to determine heterogeneous entity mappings through ontology matching process. During this procedure, it utmost importance integrate similarity measures distinguish correspondence. The way find mos...

ontology is the main infrastructure of the semantic web which provides facilities for integration, searching and sharing of information on the web. development of ontologies as the basis of semantic web and their heterogeneities have led to the existence of ontology matching. by emerging large-scale ontologies in real domain, the ontology matching systems faced with some problem like memory con...

Block heights and capillary continuity between matrix blocks play paramount role in the sensitivity analysis and therefore the history matching of cumulative oil production and production rate of carbonated fractured reservoirs. In this study, the influence of these parameters upon cumulative production and recovery factor of an Iranian fractured reservoir were studied by the usage of a sim...
