Urban planning statistics and evaluation is necessary for healthy and sustainable development of cities. However, it is not an easy task to perform statistics and evaluation because of the complexity of urban planning and the various involved data. In this paper, a GIS-based statistics and evaluation system is proposed to meet the unique requirements of the system, including multiple data type,...
for about a decade the virtual water trade has been highlighted as a means of promoting water efficiency and helping to solve regional restrictions of water resources in order to provide water and food security. although these tools are not just for certain areas of the world with a specific climate, they are more important for countries which are faced with water resources restriction and cris...
A proper valoration and operation of mining resources should consider the reaction capacity of decision makers who face contingencies and sources of uncertainty involved. The Real Options Approach makes use of financial tools to valorate real assets, incorporating these features. Although the works carried out so far now consider the abandoning, closing and reopening of a mine deposit, they hav...
Clustering is a process of dividing the data into groups of similar objects and dissimilar ones from other objects. Representation of data by fewer clusters necessarily loses fine details, but achieves simplification. Data is model by its clusters. Clustering plays an significant part in applications of data mining such as scientific data exploration, information retrieval, text mining, city-pl...
Amankwah, H. (2011). Mathematical Optimization Models and Methods for Open-Pit Mining. Doctoral dissertation. ISBN 978-91-7393-073-4. ISSN 0345-7524. Open-pit mining is an operation in which blocks from the ground are dug to extract the ore contained in them, and in this process a deeper and deeper pit is formed until the mining operation ends. Mining is often a highly complex industrial operat...
This paper is based on the open pit to underground mining practice of Daye Iron Mine. The influence mechanism between high-steep slope and non-pillar sublevel caving method is studied by using physical model test. Firstly, engineering geological properties of the choosing typical research section is analysed and generalized. Secondly, the system of open pit to underground mining is developing a...
Mining can be the source and target of opportunities threats different natures exceeding mine site perimeter, affecting socio-ecological system leading to social conflicts entrepreneurial risks for mining companies. Hence, a project is matter land planning rather than simple industrial object. Nevertheless, current mandatory risk impact assessment methods are often performed on one at time, neg...
The rise of economic globalization and evolution of information technology, financial data are being generated and accumulated at an extraordinary speed. As a result, there has been a critical need for automated approaches to effective and efficient utilization of massive amount of financial data to support companies and individuals in strategic planning and investment decisionmaking. The compe...
Many drugs are derived from small molecules produced by microorganisms and plants, so-called natural products. Natural products have diverse chemical structures, but the biosynthetic pathways producing those compounds are often organized as biosynthetic gene clusters (BGCs) and follow a highly conserved biosynthetic logic. This allows for the identification of core biosynthetic enzymes using ge...
