Traditional methods of chromite exploration are mostly based on geophysical techniques and drilling operations. They are expensive and time-consuming. Furthermore, they suffer from several shortcomings such as lack of sufficient geophysical density contrast. In order to overcome these drawbacks, the current research work is carried out to introduce a novel, automatic and opto-geometric image an...

Optimisation of oral bioavailability is a continuing challenge for the pharmaceutical and biotechnology industries. The number of potential drug candidates requiring in vivo evaluation has significantly increased with the advent of combinatorial chemistry. In addition, drug discovery programmes are increasingly forced into more lipophilic and lower solubility chemical space. To aid in the use o...

Areal mineral maps are constructed from the polished sections of particles that settle to bottom epoxy resin. However, heavy minerals can preferentially bottom, making surface rich in minerals. Therefore, will become biased estimates volumetric (3D) map. The study aims test whether any vertical cross-section (any section along settling direction particles) be an unbiased estimate 3D map a chrom...

Remote sensing has found a special technique and effective in the geological studies and mineral identification for the determination of minerals in the primary detection. The purpose of this study is to recognize the high purity calcite mineral regions in carbonate units using Aster and sentinel 2 images. Sampling of rocks and laboratory analysis using XRF and XRD for verification. The results...

Desertification is the reduction of ecologic and biologic on the earth surface, which might happen naturally or unnaturally (human). In this research, the TM and ETM images were used to study changes occurred in sand dunes during last 11 years and for determining the type of clay minerals. For evaluation of changes, maximum likelihood image classification and LMM, methods are carried out. Accor...

The multidimensional assignment problem (MAP) is a combinatorial problem where elements of a variable number of sets must be matched, in order to find a minimum cost solution. The MAP has applications in a large number of areas, and is known to be NP-hard. We survey some of the recent work being done in the determination of the asymptotic value of optimal solutions to the MAP, when costs are dr...
