Texture and color appearance of froth is a discreet qualitative tool for evaluating the performance of flotation process. The structure of a froth developed on the flotation cell has a significant effect on the grade and recovery of copper concentrate. In this work, image analysis and neural networks have been implemented to model and control the performance of such a system. The result reveals...
We study the market outcome that evolves in the long-run when price-setting firms, that compete in a differentiated market, are driven by an imitation dynamic. We find that the prices that can evolve in the long-run depend on the level of market differentiation and on the degree of oversight firms have on market decisions and outcomes. The unique symmetric pure Nash equilibrium price is always ...
Recent ideas about category learning have favored exemplar processes over prototype processes. However, research has focused on small, poorly differentiated categories and on task-final performances—both may highlight exemplar strategies. Thus, we evaluated participants' categorization strategies and standard categorization models at successive stages in the learning of smaller, less differenti...

In this work, chitosan and carboxy methyl cellulose biopolymers were used as gelling agents in composition of electrolyte of dye sensitized solar cells. The effect of both biopolymers on performance of dye sensitized solar cell were investigated by adding the same amounts of two biopolymers to the liquid electrolytes composed of ox/red couple of I-/I3- with similar concentrations. The electroch...
some properties of compounds in degrading bacteria are required for biodegradation of contaminants to higher performance. those strains which have a high percentage of these features are more effective at biodegradation. the present experiments were designed to measure these parameters. in this study, measurement of cell surface hydrophobic-degrading bacteria was designed which oil was separate...
the efficacy of activation methods and coupling were studied in the context of performance in batch and fixed bed binding experiments utilizing cell culture fluids or blood plasma as feedstock. conclusions were drawn regarding selection of solid phase according to pore size, rigidity, ph stability, chemistry of derivation and activation, and gross concentration of immobilized ligand required fo...
presently there are a number of fine and sensitive methods for determining chemical or biochemical substance among which bio electrodes represent the most recent development. bioelectrodes consist of biologically active materials (e.g enzyme, antibody, whole cell or cell fragments) held in close proximity to a suitable electrochemical transducer that sense specific electroactive enzyme substrat...
اَبَر بتن خودمتراکم (high performance high strength self compacting concrete, hphsscc)، بتن نسبتا جدیدی است بدون نیاز به ویبره و با مقاومتی حدود 800 kg/cm2 که در صورت استفاده از آن در سیستم های پس تنیده، صرفه جوئی های بیشتری نسبت به چنین بتن هائی با نیاز به ویبره را بدست خواهد داد.
Background: Leisure time activities might be associated with school performance. This study aimed to investigate the association between leisure time variables, including television and computer using time, homework time and cell phone using time, with children’s school performance in a nationally representative sample of Ira...
