Several boreholes have been drilled in the study area, though not much has been done to compare the vertical and lateral lithologic changes in the study area. This research is based on VES modelled geoelectric layers compared from point to point and using borehole logs as control data to establish inferences of certain lithology in the subsurface. The inversion of each VES curve was obtained using an AGI Earth Imager ID inversion automated computer program and resistivities and thicknesses of a geoelectric model were estimated. The analyzed VES data interpretation achieved using the curve matching technique resulted in mapping the subsurface of the area as portraying H-type;ρ<sub>1</sub> > ρ<sub>2</sub> ρ<sub>3</sub>, K-type;ρ<sub>1</sub> ρ<sub>2</sub> > ρ<sub>3</sub>, A-type;ρ<sub>1</sub> ρ<sub>2</sub> ρ<sub>3</sub>, Q-type;ρ<sub>1</sub> > ρ<sub>2</sub> > ρ<sub>3</sub>, representing 3-Layer subsurface and subsequently a combination of HK, HA and KHK types of curves representing 4-Layer and 5-Layer in the subsurface. The analysis further deployed the use of the surfer software capabilities which combined the VES data to generate profiles running in the west-east and the north-south direction. A closer analysis of the curve types indicates that there exists a sequence showing a shifting of the order of arrangement between the west and the east fragments which incidentally coincides with VES points 8, 9 and 10 in the West-East profiles. The lateral change is noted from the types of curves established and each curve indicates a vertical change in the subsurface. Control log data of lithologies from four boreholes BH1, BH2, BH3 and BH5 to show a qualification that different resistivity values portent different lithologies. Indeed, an analysis at borehole BH展开更多

The information shared on various topics often contains opinionated words which are qualitative in nature. These qualitative words need statistical computations to convert them into useful quantitative data. This data should be processed properly since it expresses opinions. Each of these opinion bearing words differs based on the significant meaning it conveys. To process the linguistic meaning of words into data and to enhance opinion mining analysis, we propose a novel weighting scheme, referred to as inferred word weighting(IWW). IWW is computed based on the significance of the word in the document(SWD) and the significance of the word in the expression(SWE) to enhance their performance. The proposed weighting methods give an analytic view and provide appropriate weights to the words compared to existing methods. In addition to the new weighting methods, another type of checking is done on the performance of text classification by including stop-words. Generally, stop-words are removed in text processing. When this new concept of including stop-words is applied to the proposed and existing weighting methods, two facts are observed:(1) Classification performance is enhanced;(2) The outcome difference between inclusion and exclusion of stop-words is smaller in the proposed methods, and larger in existing methods. The inferences provided by these observations are discussed. Experimental results of the benchmark data sets show the potential enhancement in terms of classification accuracy.展开更多

Thus, with the flow of the glacier, what should appear on the time-dependent cumulative effect of strain-rate? How does it affect the glacial structure? Based upon the study on the distribution of strain-rate on the surface of No. 1 Glacier at the head of the Wulumuqi River, Tianshan (for short, No. 1 Glacier), the following is a report on this problem.展开更多

This systemic precipitants that promote aggressive atherogenesis have been confirmed in multiple studies showing a relationship between atherosclerotic disease in one vascular bed with disease in another. However, the strength of this relationship varies from patient to patient. Thus, the practical utility of the diffuse nature of atheresclerosis is questionable. Ge and colleagues have proposed the use of left main (LM)coronary artery disease as a potential marker for left anterior descending (lAD) atherosclerotic disease. At first thought, this seems useless since the evaluation of the LM (by angiography or IVUS) can just as easily be performed in the LAD so why bother searching for such a surrogate? However, newer (non-invasive) imaging modalifies are making great gains and will be able to reliably image the LM sooner than the LAD (especially the distal LAD) so such a surrogate could have practical applications.展开更多
