Advancing resistivity-chargeability modeling for complex subsurface characterization using machine learning and deep learning
Adedibu Sunny Akingboye, Andy Anderson Bery, Hui Tang +4
Subsurface lithological heterogeneity presents challenges for traditional geophysical methods, particularly in resolving nonlinear electrical resistivity and induced polarization (…
Quantum nondemolition measurement operator with spontaneous emission
Ebubechukwu O. Ilo-Okeke, Tim Byrnes
We present a theory for quantum nondemolition (QND) measurements of an atomic ensemble in the presence of spontaneous emission. We derive the master equation that governs the evolu…
Principal Component Analysis of Ground Level Enhancement of Cosmic Ray Events
R. E. Ugwoke, A. A. Ubachukwu, J. O. Urama +3
We applied principal component analysis (PCA) to the study of five ground level enhancement (GLE) of cosmic ray (CR) events. The nature of the multivariate data involved makes PCA…
Hybrid approximation approach to generation of atomic squeezing with quantum nondemolition measurements
Ebubechukwu O. Ilo-Okeke, Manikandan Kondappan, Ping Chen +3
We analyze a scheme that uses quantum nondemolition measurements to induce squeezing of a spinor Bose-Einstein condensate in a double well trap. In a previous paper [Ilo-Okeke et a…
Quality Assessment of the 20m SPOT DEM in Nigeria
Peter Nwilo, Johanson Onyegbula, Chukwuma Okolie +3
The 20m SPOT DEM (Digital Elevation Model) was acquired by the Office of the Surveyor-General of the Federation (OSGoF) in Nigeria for use in topographic mapping. A localized asses…
Positional Accuracy Assessment of Historical Google Earth Imagery
Peter C. Nwilo., Chukwuma J. Okolie, Johanson C. Onyegbula +6
Google Earth is the most popular virtual globe in use today. Given its popularity and usefulness, most users do not pay close attention to the positional accuracy of the imagery, a…
