A computer controlled semiclosed net CO(2) exchange measurement system, employing an infrared gas analyzer and mass flow controllers to inject pure CO(2) at preset rates, has been developed for measuring whole plant net CO(2) exchange and net C gain in a controlled environment (i.e. CO(2), light, and temperature). Data for tomato (Lycoperscicon esculentum cv Campbell 19 VF) and rose (Rosa hybri...

Transport phenomena through hollow fiber membrane contactors (HFMCs) indicate the exchange of a component between two phases, inside and outside fibers. In this research, we designed fabricated lab-made HFMCs to assess difference water air as sweeping media for CO2 exchange. The effects flow rates temperature ratios on aqueous absorption were investigated accordingly. A semiclosed circuit incor...

We present a parameter free and monotonic alternative to the parametric variable precision model of rough set data analysis. The proposed model is based on the well known PRE index λ of Goodman and Kruskal. Using a weighted λ model it is possible to define a two dimensional space based on (Rough) sensitivity and (Rough) specificity, for which the monotonicity of sensitivity in a chain of sets i...
