| Abstract | This paper presents a method to identify the maturity of durian using radar equation. The measurement system consists of two identical square patch antennas acting as a transmitter and a receiver. The return loss of the transmitter and the transmission coefficient at the receiver are measured using network analyzer. These measured data are used to determine the ratio of the effective reflection coefficients for two different frequencies at the interface between air and durian. In this step, the radar equation is applied. In this experiment, ten mature and ten immature durians are chosen by an experienced farmer. The measured data of fourteen durians are used for training the system using the support vector classification. The measured data of another six durians are used for testing the system. The results show that the performance of the system is acceptable. |

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.
