This paper explores the use of a hierarchical neuro-fuzzy model for image classification of macroscopic rock texture. The relevance of this study is to help Geologists in diagnosing and planning the oil reservoir exploitation. The same methodology can be also applied to metals, in order to classify the different types of materials based on their grain texture. We present an image classification...

The Sonju Lake intrusion (SLI) is a 1200-m-thick, shallow-dipping, sheet-like intrusion that forms part of the Beaver Bay Complex (RI-58, Chapter 7). Although its exposed strike-length is only about 3 km (Fig. 3-1), the SLI has a distinctive aeromagnetic signature that can be traced for at least 20 km beneath a cover of glacial drift. The nearly constant width of its aeromagnetic anomaly sugges...

The current trend in the development of self-compacting concrete with sustainable construction materials has served as a guide to design novel concrete, siderurgical by-products (steel slag aggregates and cupola powder supplementary cementing material) that also meets demands high-performance concrete. This research sets out clarify unknown behavior its durability, which is ability withstand an...

The work is devoted to the results of processing electromagnetic radiation signals obtained during laboratory loading marble and diabase samples using a technique for determining parameters microcracks, developed published by author earlier. As result such processing, certain patterns were found in nature evolution oscillatory process ensemble microcracks. For example, solitary non-linear waves...

To accurately obtain the tensile strength of rock and fully understand evolution process failure is one key issues to research mechanics theories mass engineering applications. Using direct tensile, Brazilian splitting, three-point bending test methods, we performed indoor numerical simulation experiments on marble, granite, diabase investigated damage several typical rocks in three different t...

The aeromagnetic data of Nkalagu and Abakaliki areas were interpreted using spectral analysis modeling to estimate depth the sedimentary thickness, nature intrusive, susceptibility values types minerals associated with them. total magnetic intensity was processed produce residual map which divided into 21 overlapping blocks. Each block subjected a program plot (SPP) developed MATLAB obtain dept...
