Experimental Validation of Percolation-based Models for Propagation Prediction

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Experimental validation of photoacoustic k-space propagation models

Propagation models to predict the temporal output of a sensor in response to an arbitrary photoacoustically generated initial pressure distribution have been developed. k-space (frequency-wavenumber) implementations have been studied with the aim of producing fast and accurate predictions. The k-space models have several advantages. They may be implemented using the Fast Fourier transform, whic...

Validation of biomarker-based risk prediction models.

The increasing availability and use of predictive models to facilitate informed decision making highlights the need for careful assessment of the validity of these models. In particular, models involving biomarkers require careful validation for two reasons: issues with overfitting when complex models involve a large number of biomarkers, and interlaboratory variation in assays used to measure ...

Propagation Prediction Models

To implement a mobile radio system, wave propagation models are necessary to determine propagation characteristics for any arbitrary installation. The predictions are required for a proper coverage planning, the determination of multipath effects as well as for interference and cell calculations, which are the basis for the high-level network planning process. In a GSM/DCS-system the high-level...
