| Abstract | A portable electronic nose system has been developed with an array of five commercially available Metal Oxide Semiconductor (MOS) sensors, where a microcontroller (muc) is used for the pattern recognition. The classification of black tea aroma is carried out in the muc (PIC18F4520) and is based on feed forward multilayer perceptron (FF-MLP) algorithm. With the samples collected from the different gardens of north-east and eastern India, the MLP is trained first using the back-propagation algorithm with the fingerprint from the sensor array and the corresponding tea tasters' mark in a PC to obtain the optimum architecture and weights and biases of the neurons. Once it is trained, the computed weights and biases of the neurons are programmed in the muc and it then becomes a portable instrument, which gives the aroma index directly for new unknown tea samples. It is observed from the results that the performance of the muc-based electronic nose is at par with that of the PC-based electronic nose system when compared with unknown finished black tea samples. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
