Abstract | The monitoring of river water quality plays an important role in the management of the integrated urban water resource. The high non-linearity, time-variability and uncertainty in river systems as well as the problems of high cost and low reliability caused by on-line sensors make it inconvenient to implement online sensors for monitoring river water quality. An interval observer is robust against uncertainties on the kinetics of the process and the additional disturbances on a system. Based on the River Water Quality Model no. 1 (RWQM1) issued by the International Water Association, a software sensor aimed at river water quality was constructed by adopting interval observers, and the operation of the river water quality interval observers were simulated. Simulation shows that this software sensor may give reasonable dynamical bounds respected by the true values of the non-measured variables and realize online accurate monitoring of river water quality even though there exists uncertainty in river inputs caused by the urban wastewater system. |

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.
