| Abstract | The arterial tree is depicted as a single transmission line of tapered characteristic impedance with a nonlinear load. This load contains a Zener diode to simulate the 'Waterfall' behaviour caused by smooth muscle tension around the resistance vessels. A shunt resistor represents arterio-venous shunts. The waterfall reference pressure is related to the peripheral blood flow by a feedback coefficient with a time-constant. This combination provides realistic aortic pressure and flow waveforms and an aortic input impedance similar to a 'Windkessel' model. To demonstrate low-frequency responses, the amplitude of the input signal is modulated by a binary, pseudo-random noise waveform, synchronised to the pulse and 63 pulse periods long. |

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.
