The electronic nose (EN) seems to represent a good solution for the detection of cancers of different types. Recent results showed the utility of an EN to smell chemicals related to lung, melanoma, prostatic, breast and pancreatic cancers. The results obtainable from ENs are chemical images and...
An electronic nose (e-nose) is an artificial sensor system that generally consists of an array of chemical sensors for detection of volatile organic compound profiles (breathprints) and an algorithm for pattern recognition. E-noses are handheld, portable devices that provide immediate results. E-...
"When adding oxygen, our results became better and more reliable, since oxygen releases substances from the wine. You can compare it to when a sommelier aerates wine before tasting," Chilo says. One advantage is its high reliability, but the method's main competitive advantage is speed. More...
The electronic nose system coupled to SVM could discriminate between unspoiled/ spoiled beef or sheep meats with a success rate of 98.81 or 96.43 %, respectively. To investigate whether the results of the electronic nose correlated well with the results of the bacteriological analysis, partial least...
These results suggest that this E-nose system is capable to discriminate and quantify CWA mimics and it would be a feasible system to be used in a real scenario.doi:10.1016/j.snb.2014.05.060Cristian OlguinCentro de Reconocimiento Molecular y Desarrollo Tecnologico (IDM)Nicolas Laguarda-Miro...
These results show the potential application of neural network based e-noses to test the quality of potable water as an alternative to instruments, such as liquid chromatography or optical microscopy. 展开 关键词: Practical, Experimental/ array signal processing ART neural nets fuzzy neural nets gas...
Principal component analysis of the E-nose results clearly differentiated the samples related to drying time, and it was found that samples of initial stages (0 h, 3 h, and 6 h) had strong positive with different sensors. Partial least squares-discriminant analysis (PLS-DA) indicated that ...
A slower spoilage rate was observed in MAP storage than in iced. The electronic nose measurements are generally in agreement with the results of sensory evaluation, but give detailed information about the spoilage pattern and the composition of the headspace of red fish. 展开 ...
.The used odor releaser/absorber system was suitable to study the aroma transfer.Sensory tests showed performance differences among four freezer plastic bags.The scoring test effectively exhibited different levels of sensory contaminations.Electronic nose responses were correlated with the sensory results....
