Abstract Outcrop mapping as well electromagnetic and ground magnetic surveys was carried out within Auchi Igarra localities in order to attempt an interpretation of the geology areas delineate boundary between basement sedimentary terrains. Geologic done by collecting samples outcrops at five different locations areas. Three lithofacies were identified area they are basal shale unit, tabular cr...

this paper intends to compare the abilities of the two major imaging modalities in nuclear medicine imaging: positron emission tomography (pet) and single photon emission computed tomography (spect). the motivations are many-fold: (i) to gain a better understanding of the strengths and limitations of the two imaging modalities in the context of recent and ongoing developments in hardware and so...

The subsurface in areas affected by the Pleistocene glaciations often reveal very complex architectures and because of this, near-surface geology is generally difficult to map model high detail. A number geophysical methods focus on uppermost part are capable mapping details, but no single method has hitherto been able provide detail, data density resolution required Quaternary 3D. Driven deman...

This article investigates a rotational data collection strategy for planar array electrical capacitance tomography (ECT) to improve the imaging of complex-shaped objects in scenarios, where access object is limited. Planar ECT can produce 2-D and 3-D images changes dielectric permittivity object, but detecting may require more electrodes array, which decrease quality measurements make it challe...

planar d-bar integral equation is one of the inverse scattering solution methods for complex problems including inverse conductivity considered in applications such as electrical impedance tomography (eit). recently two different methodologies are considered for the numerical solution of d-bar integrals equation, namely product integrals and multigrid. the first one involves high computational ...
