| Abstract | This paper presents the Optical Cochlear Implant Simulator (OCIS), a linear filter-based model which extends laboratory measurements of optical cochlear implant performance to allow investigation of the design space for these new devices which are an alternative to traditional cochlear implants utilizing electrode arrays. In order to determine the bandpass for each channel of the optical cochlear implant for a specific center frequency, a Monte Carlo simulation is employed to simulate photon absorption by the cochlear tissue. The simulation results matches experimental data obtained previously by Izzo et al for a given point on the cochlea. OCIS employs a variable bandpass for each filter bank element correlating with the location of the center frequency band to the tonotopic map of the cochlea. OCIS synthesizes spectrally reduced speech simulating multi-channel optical cochlear implant output waveforms. Example time domain and spectrogram plots of simulated spectrally reduced speech are included. |

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.
