| Abstract | Basing on the recent outcomes of an investigation on the water content evaluation from processing the GPR signal in the frequency domain, an accurate model for the prediction of the frequency spectrum of the reflected GPR signal as the moisture content changes is proposed. This method uses an Artificial Neural Network approach. After the training, the ANN is reasonably able to predict the frequency spectrum for a water content in a specific soil (the error in the spectrum generation computed on a validation set, after 105 training epochs, is about or less than 10% for the same soil, if the ANN is used for all kinds of soil the error increases to about 15-20%). Of course this method can be inverted generating with the trained ANN a catalogue of different spectra for different values of the soil water moisture. Using this inverse approach it is possible to predict the water content of a specific soil just comparing the real current spectrum of the reflected GPR signal with the spectra of the catalogue. This method has been successfully tested on experimental data. |

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.
