soil erosion causes sediments to be detached from their source materials and transported as suspended particles. the present study was conducted to evaluate the effects of sand exploitation on the distribution of suspended sediments in the educational and research forest watershed of tarbiat modares university, which comprises approximately 50,000 ha. fifty-one water samples were collected befo...

This paper addresses the problem of semi-automatic design of workflows for complex knowledge discovery tasks. Assembly of optimized knowledge discovery workflows requires awareness of and extensive knowledge about the principles and mutual relations between diverse data processing and mining algorithms. We aim at alleviating this burden by automatically proposing workflows for the given type of...

Abstract: Autonomous guidance of the mining vehicle is based on the path tracking algorithm that use pre-calculated desired paths. These paths are often calculated without taking into account the nonholonomic nature of the vehicle motion. As a result the calculated path might be not feasible and the path tracking controller will be required to correct the situation, deteriorating at the same ti...

rajasthan is one of the main mineral potential state of india. during the last 30 years it has witnessed enormous expansion of mining industries, but mining of most of the minor minerals coupled with changing climate has posed serious problems to the environmental fabric in the state, apart from base metal beneficiation plants. groundwater is also being polluted day-by-day by effluents generate...

Aims and background: Mining and energy complexes in Serbia are recognized as a major source of a large number of pollutants. Serbia’s environmental performance reports clearly indicate that large mining and energy complexes are the dominant source of air pollution. It is difficult to determine which of them remarkably threaten the quality of the environment, as all the basic elements of the env...

Urban planning is a knowledge-intensive activity. It acquires useful knowledge by analysing jointly socio-economic data and topographic maps. When supported by computers, this preliminary information gathering triggers a knowledge discovery process, which often consists of exploratory data analysis tasks. Advances in georeferencing have caused among the other things a growing demand for more po...

We study a daily mine planning problem where, given a set of blocks we wish to mine, our task is to generate a mining sequence for the excavators such that blending resource constraints are met at various stages of the sequence. Such time-oriented resource constraints are not traditionally handled well by automated planners. On the other hand, the remaining problem involves finding node-disjoin...
