Artificial Noses and Ears

Odor to sensor space transformations in biological and artificial noses

Electronic Noses and Applications

Electronic noses are customized devices employed to detect and to identify gaseous mixtures, even to give the concentration of the atmosphere components. Nowadays, the research in this domain is more and more growing, in Europe and other countries in the world, for many applications, such as environmental protection, food industries, perfumery, public safety, medicine, and pharmacy. Electronic ...

Electronic Noses and Their Applications

Electronic/artificial noses are being developed as systems for the automated detection and classification of odors, vapors, and gases. An electronic nose is generally composed of a chemical sensing system (e.g., sensor array or spectrometer) and a pattern recognition system (e.g., artificial neural network). We are developing electronic noses for the automated identification of volatile chemica...

Simulation of Artificial Noses for the Automated Detection and Classification of Organic Compounds

This paper is an introduction of Artificial Neural Networks. Mainly deals with an exciting application of neural network called “Electronic Nose”. The idea behind this application is simple. Electronic/Artificial noses are being developed as the systems for automated detection and classification of odors, vapors and gases. To avoid domestic accidents in the houses, small scale industries or min...

The Lowdown on Noses

The Earth’s early environment was relatively poor in oxygen, and observations and modeling indicate that the rise in oxygen levels did not occur until long after oxygen-enriching bacterial photosynthesis had developed. Catling et al. (p. 839; see the Perspective by Kasting) explain the apparent disconnect between oxygenation and the start of photosynthesis by adding methanogenesis to the proces...
