In this paper we present a novel Point-based pattern analysis for predicting Cassiterite (tin-ore) as a secondary mineral deposit in the Plateau Younger Granite Region of Nigeria (PYGR) using statistics, spatial analysis and machine learning techniques. Existing mining data points collected from field survey in the PYGR and the geological map of the region were digitized and converted into shap...

(1) Let P, Q be subsets of E2 T, p1, p2, q1 be points of E2 T, f be a map from I into (E2 T) P, and s1 be a real number. Suppose that P is an arc from p1 to p2 and q1 ∈ P and q1 ∈ Q and f (s1) = q1 and f is a homeomorphism and f (0) = p1 and f (1) = p2 and 0 ≤ s1 and s1 ≤ 1 and for every real number t such that 0 ≤ t and t < s1 holds f (t) / ∈ Q. Let g be a map from I into (E2 T) P and s2 be a ...

In this paper, a method integrating NC decoding and solid milling simulation to solve this problem is proposed. A modified Z-Map computational algorithm is adopted and it directly uses straight line and arc interpolation algorithms to calculate mesh position and Z coordinates of tool scanning surface according to tool path and initial tool scanning boundary in reducing the long computation time...

Earthquake, flood, and drought data from different sources are combined in a single data set using the same data structure, projection, and scale. The intensity and frequency of each hazard is classified into severe, heavy, modest, and light, producing a dassification with 64 combined states for the three kinds of hazard. These classes are then ranked according to severity. The three hazard cov...

It has been suggested that post-orogenic lithospheric removal in continental back arcs promotes extension and surface subsidence. However, the surface response of this process and its primary difference from “classical” back-arc opening have remained uncertain. Here, the back-arc extension process with varying continental mantle lithosphere thickness and thermal heterogeneities is studied by us...

the makran subduction zone in southeastern iran and southern pakistan is where the oceanic crust of the arabian plate (oman sea) is subducting beneath eurasia. compared to other subduction zones in the world, the makran subduction zone has some unusual features, including different seismicity patterns in its eastern and western parts. also, the quaternary volcanoes in the eastern part of makran...

An arc fault is the leading cause of electrical fire. Aiming at problems difficulty in manually extracting features, poor generalization ability models and low prediction accuracy traditional detection algorithms, this paper proposes a method based on fusion channel attention mechanism residual network model. This to perform global average pooling information from each feature map assigned by b...

The locally linear embedding (LLE) algorithm is useful for analyzing sets of very different geoscientific images, ranging from smooth potential field images, to sharp outputs from modeling fracturing and fluid flows via cellular automata, to hand sketches of geological sections. LLE maps the very high-dimensional space embedding the images into 2-D, arranging the images on a plane. This arrange...

Received: 20 August 2004 Revised: 19 January 2005 Accepted: 24 January 2005 Online publication date: 3 March 2005 Abstract One of the main tasks in exploratory data analysis is to create an appropriate representation for complex data. In this paper, the problem of creating a representation for observations lying on a low-dimensional manifold embedded in high-dimensional coordinates is considere...
