co2/ch4 gas separation is a very important applicatable process in upgrading the natural gas and landfil gas recovery. in this work, to investigate the membrane separation process performance, the gas permeation results andco2/ch4 separation characteristics of different prepared membranes (via blending different molecular weights of polyethylene glycol (peg) as a modifier with acrylonitrile-but...

In many applications, there is a need to blindly separate independent sources from their linear instantaneous mixtures while the mixing matrix or source properties are slowly or abruptly changing in time. The easiest way to separate the data is to consider off-line estimation of the model parameters repeatedly in time shifting window. Another popular method is the stochastic natural gradient al...

In order to solve problems such as poor applicability of headers, weak separation ability threshing mechanisms and impurity-removal cleaning devices in the existing seed harvest methods Chinese milk vetch (Astragalus sinicus L.), a combined harvester was designed this paper. The parameters key components, flexible anti pod-dropping seedling-lifting header, longitudinal rod-teeth-type device air...

Rice is a widely cultivated food crop worldwide, and threshing one of the most important operations combine harvesters in grain production. It complex, nonlinear, multi-parameter physical process. The flexible device has unique advantages reducing damage rate already been major concerns engineering design. Using measured test database bench, rotation speed cylinder (RS), clearance concave sieve...

Combine harvesters are widely used worldwide in harvesting many crops, and they have functions that cover the entire process, such as cutting, threshing, separating, cleaning. The threshing drum is core working device of combine harvester plays an influential role rice efficiency, power requirement, seed loss. In this study, two structures threshers (conical-shaped cylindrical-shaped) were test...
