Petro physics, rock physics and multi-attribute analysis have been employed in an integrated approach to delineate porosity variation across Tamag Field of Niger Delta Basin. Gamma and resistivity logs were employed to identify sand bodies and correlated across the field. Petro physical analysis was undertaken. Rock physics modelling and multi-attribute analysis were carried out. Two hydrocarbo...

In this paper, we describe research in fundamental frequency modeling based on a statistical learning technique called additive models. A two-layer additive F0 model consists of a long-term, intonational phrase-level component, and a short-term, accentual phrase-level component. It can be learned from the data using a backfitting algorithm, an optimizer of a penalized least-square criterion def...

The purpose of mineral exploration is to find ore deposits. The main aim of this work is to use the fuzzy inference system to integrate the exploration layers including the geological, remote sensing, geochemical, and magnetic data. The studied area was the porphyry copper deposit of the Kahang area in the preliminary stage of exploration. Overlaying of rock units and tectonic layers were used ...

Homogeneous charge compression ignition (HCCI) is a futuristic combustion technology that operates with high efficiency and reduced emissions. HCCI combustion is characterized by complex nonlinear dynamics which necessitates the use of a predictive model in controller design. Developing a physics based model for HCCI involves significant development times and associated costs arising from devel...

Understanding anion adsorption mechanisms is necessary to allow prediction of anion adsorption behavior. This study was conducted to evaluate the ability of the triple layer model, a chemical surface complexation model, to describe the effect of changes in solution ionic strength (0.01-1.0 M NaCl) and solution pH (3-11) on B adsorption by the iron oxide, goethite, the aluminum oxide, gibbsite, ...

This research focuses on the study of a new material, layered double hydroxide, which was synthesized using co-precipitation method at pH constant and, then, tested for its retention nitrate anions. The LDH prepared from four metal cations Mg-Zn-Co-Al to produce quadratic material mentioned, Mg Zn Co Al-CO3, calcined obtain oxides. Different techniques characterization were considered, namely F...

Adsorption is one of the several techniques that has been successfully used for dyes removal. Since most industrial colored effluents contain several components including dyes, having a strong knowledge about the scope of competitive adsorption process is a powerful key to design an appropriate system. This is mainly because of the complexity brought about by the increasing number of parameters...

Rock physics models allow establishing a physical-mathematical relation between rock and fluid properties and geophysical attributes. In this study, we propose to apply rock physics models to a geophysical dataset measured at two well locations near the proposed Snake River Plain FORGE site in eastern Idaho. The potential target is a rhyolite layer, which occurs between 2,000 and 3,000 m. The a...
