| Abstract | Dielectric spectroscopy is applied to investigate the feasibility of biofuel composition measurement. Measurements were made on the pure components (ethanol, gasoline and water) and mixtures thereof. Preliminary measurement results indicate that the components have distinguishable spectral dielectric behavior in the ranges 10-100 kHz and 200 MHz-2GHz. A simple linear-mixing algorithm is presented for calculating the composition from two different parameters of the measured data. Measurements show that ethanol concentration is relatively easy to determine by RF impedance measurements of the permittivity of the mixture, provided that the baseline is compensated for the water content. Unambiguous measurement of water content of different types of fuel at low frequencies is still hampered by the salinity of water and the presence of additives (static dissipaters) that lower the conductivity of gasoline. |

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.
