A novel sea mine computer-aided-detection / computer-aided-classification (CAD/CAC) processing string has been developed. The overall CAD/CAC processing string consists of pre-processing, adaptive clutter filtering (ACF), normalization, detection, feature extraction, feature orthogonalization, optimal subset feature selection, classification and fusion processing blocks. The range-dimension ACF...

An acid metal-contaminated soil from the Aljustrel mining area (a pyrite mine located in SW Portugal in the Iberian Pyrite Belt) was subjected to chemical characterisation and total metal quantification (Cd, Cr, Cu, Ni, Pb and Zn). Water-soluble metals were determined and a sequential extraction procedure was used to investigate metal speciation. Two bioavailable metal fractions were determined...

Surface coal mine spoil was studied to evaluate selenium (Se) mobility and solubility using batch experiments, column-Ieachmg techniques, and sequential and individual extraction processes. Both selenite and selenate followed linear isotherm patterns at relatively lower Se treatments, whereas over a broader solution Se concentraton range the sorption mechanism followed the Lanpuir model. The va...

Information extraction approaches have been successfully applied to mine the scientific literature in biology and medicine. So far, the main focus of research and development in this domain was on the recognition and extraction of gene and protein names in the context of molecular biology and genome research and on disease names and other medical terms in the context of clinical research. Simil...

Determination a sequence of extracting ore is one of the most important problems in mine annual production scheduling. Production scheduling affects mining performance especially in a poly-metallic open pit mine with considering the imposed operational and physical constraints mandated by high levels of reliability in relation to the obtained actual results. One of the important operational con...

Surface movement under the combined mining of open-pit and underground caving is main problem affecting safe efficient mining. Taking Dahongshan Iron Mine as an example, a mechanical model for calculating surface range was established to reveal mechanism. The topography, zone, gravel filling zone depth were considered, principal stress calculated. Based on model, relationship between subsidence...

abandoned surface mine excavations can be a major environmental, social and/or human healthproblem for the mining industry as well as for the community living nearby. this problem is exacerbated by therapidly growing population encroaching on areas of historic mined lands. the aim of this studywas to assess thesafety status of the historic nyala mine excavation with the purpose of coming up wit...

The activities of mining exploitation in Campo de Jales were performed in an uncontrolled way and gave rise to serious environmental contamination: rubbish depositories have been accumulated with no treatment or maintenance. An investigation developed around Jales Mine showed the existence of some chemical impact originated from the waste produced during mining activities. Some "black spots" fo...

In this paper a new authentication system using Finger Back Knuckle Surface is examined. This paper is intended to propose an effectual method for personal authentication using Finger Back Knuckle Surface. This method take advantage of the less number of features extracted from the Finger Back Knuckle Surface and the Angular geometric analysis is done to mine the distinguishable feature informa...

The data extraction from the dynamically generated web pages is a challenging factor because the result of the search engines are always different for every query submitted. Many techniques were proposed to address this issue but most of them have the common problem of language-dependency. In order to overcome the limitations of previous works, there are few ways which analyze visual features o...
