in this study, the possibility of producing coal with less than 11% ash from tailings of flotation process was investigated. the effect of six flotation parameters: collector type, collector consumption, frother type, frother consumption, pulp density and mixing rate were studied on a sample from a tailing dam. a software based experimental design approach (dx7) was applied to determine and mod...

This is a revision of a book which has already become established as an authoritative text on the design of experiments. It gives both an exposition of the practical aspects of this subject, as interpreted in modern statistics, and also a brief account of the mathematical model underlying each design. It is assumed that the reader has previously had an introduction to statistical methods, parti...

in design of experiments, analysis and identifying those variables that affect the outputs are of interest. response surface methodology is a mathematical-statistical method to optimize the experiment outputs. this method tries to find the best response levels by optimizing the design variables called factors. in many engineering applications, robust design has become the most important issues....

Individual-based modelling and analysis of forest experiments has been made more accessible to researchers with the advent of modelling environments like Simile from Simulistics.com. Individual-based analyses of tree growth data offer insights not possible with plot-based analyses, especially when the original experimental design has been compromised by mortality or other unforeseen events. The...

In this paper, we present a novel approach to software failure detection based on pattern position distributions as features. In this approach, we divide an execution sequence into several sections and then compute a pattern distribution in each section. The distribution of all patterns is then used as a feature to train a classifier. This approach outperforms conventional frequency based metho...

The interest in drug combinations is growing rapidly due to the opportunities they create to increase the therapeutic effect and to reduce the frequency or magnitude of undesirable side effects when single drugs fail to deliver satisfactory results. Considerable effort in studying the mechanisms leading to the benefits of the joint action of drugs has been matched by the development of relevant...
