a new parametric model was developed for predicting cut point of hydraulic classifiers. the model directly uses operating parameters including pulp flowrate, feed particle size characteristics, pulp solids content, solid density and particles retention time in the classification chamber and also covers uncontrollable errors using calibration constants. the model applicability was first verified...

Graph cut problems are widely studied in the area of approximation algorithms. The most basic cut problem is the s-t minimum cut problem, for which Ford and Fulkerson gave an exact algorithm and illustrated max-flow min-cut relationship. This min-max theorem has led researchers to seek its generalization to the case of multicommodity flow. In this setting, each commodity has its own source and ...

Dendrocalamus hamiltonii, a large, clump-forming bamboo, has great potential to contribute towards poverty alleviation efforts across its distributional range. Harvesting methods that maximize yield while they fulfill local objectives and ensure sustainability are a research priority. Documenting local ecological knowledge on the species and identifying local users' goals for its production, we...
