Interrelationship of hydrology, microbial colonisation and hydrometallurgy in a simulated chalcopyrite heap leach [PDF]
, 2008 Includes bibliographical references (leaves 104-115).Chalcopyrite is the most abundant primary copper sulphide mineral found worldwide. As copper grades of ores available for extraction decrease, heap bioleaching is gaining interest as a potential ...

Spatio-temporal modelling of dengue fever incidence in Malaysia [PDF]
, 2017 Previous studies reported significant relationship between dengue incidence rate (DIR) and both climatic and non-climatic factors. Therefore, this study proposes a generalised additive model (GAM) framework for dengue risk in Malaysia by using both ...

Design and development of a machine vision system using artificial neural network-based algorithm for automated coal characterization [PDF]
, 2020 Coal is heterogeneous in nature, and thus the characterization of coal is essential before its use for a specific purpose. Thus, the current study aims to develop a machine vision system for automated coal characterizations.

A Feature Extraction Method Using Auditory Nerve Response for Collapsing Coal-Gangue Recognition
Applied Sciences, 2020 To intelligentize the top-coal caving’s process, many data-driven coal-gangue recognition techniques have been proposed recently. However, practical applications of these techniques are hindered by coal mine underground’s high background noise and ...
