Application in Mixed Gas Identification

چکیده
We promote a qualitative analysis algorithm to intelligently identify the ammonia, ethanol and their mixture. This work based on an electronic nose with a set of specific gas senor array building in a temperature controlled mini-cavity. A BP neural network has been trained for identification the samples inputs which preprocessed by principal component analysis (PCA) or linear discriminant analysis (LDA) method for dimension reduction. Results showed that ammonia, ethanol and different proportions of their mixture can be identified accurately. And the LDA performed better on dimension reduction in this case.

متن کاملIdentification of Gas Accumulation Adjacent to the Gas Hydrate Bearing Zone by Inversion Utilizing AVO Attribute
The presence of gas hydrate and associated gas in the Makran Accretionary Prism, offshore Iran, has been confirmed by various seismic indicators, including the bottom-simulating reflector (BSR), amplitude blanking, and bright spot. The pre-stack analysis and the study of amplitude-variation-with-offset (AVO) attributes are the most reliable tools for semi-quantitative study of gas hydrate and f...
متن کاملGeological Identification and Storage Capacity of Suitable formation for CO2 disposal in Eastern Zagros (Fars area), Iran
Climate change is one of the major global concerns. Emission of anthropogenic greenhouse gases is the main cause of climate change. One way of reducing the emissions is the application of carbon capture and storage (CCS) in geological formations. In this study, feasibility of CCS was studied in an Iranian gas production area located in the northern Persian Gulf coast in the south of country. Th...

In this study we developed LaNixAl1-xO3 perovskite systems using a sol-gelmethod (with propionic acid as solvent) to use in methane-reforming reactions for producing synthesis gas. To understand the roles of the nature of the precursor and calcination conditions on the formation of LaNixAl1-xO3, we carried out identifications using NMR, FT-IR, XRD, SEM, and TEM. The precursor struc...
