A geophysical method of investigation has been deployed in order to give a quick overview the nature and rapidly changing subsurface lithologies that characterized Yikpata, Share, Kwara State, Nigeria. total nine (9) vertical electrical soundings (VES), using Schlumberger Array uniformly divided into three groups: basement, basement/sedimentary boundary sedimentary terrain, horizontal profiling...

We examined the uncertainty of two-dimensional (2D) resistivity method using conceptual cavity models. The experimental study was conducted to validate numerical model results. Spatial resolution and sensitivity perturbations were also assessed checkerboard tests. Conceptual models simulated generate synthetic data for dipole-dipole (DD), pole-dipole (PD), Wenner–Schlumberger (WS), pole-pole (P...

Many mathematicians have a dismissive attitude towards paradoxes. This is unfortunate , because many paradoxes are rich in content, having connections with serious mathematical ideas as well as having pedagogical value in teaching elementary logical reasoning. An excellent example is the so-called " surprise examination paradox " (described below), which is an argument that seems at first to be...
