|Abstract||The aim of the research reported is to put the laboratory application of closed-loop digital computer systems to experimental control and analysis in biology and behavioral science on a formal basis, using special concepts of programming to quantitatively control different parameters of variation in sensory feedback of specific response systems. The theory is unconventional in that the computer and the techniques of closed-loop programming are designed to control time delays, space displacements, kinetic modulations, and informational and symbolic transformations in the sensory feedback that is generated by movements and/or physiological actions of the living subject.The present experiment illustrates application of the system and the methods of closed-loop perturbation programming to study of delayed auditory feedback of speech. The subject's speech is transduced, amplified, converted by an analog-to-digital converter, programmed for delays, deconverted by a digital-to-analog converter, filtered, amplified, and then used to activate protected earphones on the speaker's ears. The computer is also used to introduce many special perturbation of the auditory feedback of speech in real time.|

Ministry of Human Resource Development (MHRD) under its National Mission on Education through Information and Communication Technology (NMEICT) has initiated the National Digital Library of India (NDLI) project to develop a framework of virtual repository of learning resources with a single-window search facility. Filtered and federated searching is employed to facilitate focused searching so that learners can find out the right resource with least effort and in minimum time. NDLI is designed to hold content of any language and provides interface support for leading vernacular languages, (currently Hindi, Bengali and several other languages are available). It is designed 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 being developed to help students to prepare for entrance and competitive examinations, 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 being developed at 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 Human Resource Development (MHRD), through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
