Abstract | We present an integrated software environment that enables sleep specialists to analyze, quantity and diagnose sleep disordered breathing based upon time-domain, frequency-domain, and nonlinear dynamics measurement measures of heart rate variability (HRV) signal. The integrated graphical user interface (GUT) and the signal processing algorithms were developed and implemented in MATLAB, This environment provides the facility to import or read sleep data (ECG, EEG, blood pressure, respiratory, oxygen saturation, etc.) under user control and displays them individually or collectively in a data window for visual inspection. It then enables the user to clip the length of data to be used in carrying out the analysis. Raw ECG data is preprocessed for reliable QRS detection and the HRV signal is derived following the guidelines of the Task Force of the European Society of Cardiology and the North American Society for Pacing and Electrophysiology, which is then displayed along with respiration signal in the analysis window. After this step time-domain, frequency- domain, and nonlinear dynamics analyses of the HRV signal are performed to extract sensitive measures used in detecting and diagnosing sleep disordered breathing. The computer analysis can then generate a complete report for the specialist and further statistical and/or automatic analyses. The system was developed and validated using data from the MIT-BIH Polysomnographic Database. After validation and reliability testing it was used to analyze sleep data for detection of sleep disordered breathing (SDB) in children. Data from normal and children diagnosed with SDB showed that the system could potentially distinguish between normal children and children suffering from sleep disordered breathing. |

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.
