| Abstract | The Remote Patient Monitoring (RPM) is becoming vital part of healthcare improving quality of care. The RPM system uses variety of sensors and wireless technologies to monitor multiple biological and environmental signals simultaneously providing status and trend data for the patient. The RPM system can also provide alarms/alerts for the patient or the caregiver in real-time so that the patient gets assistance in timely manner when an acute event occurs. The RPM system must detect such events in real-time to generate alarms/alerts. Use of mobile devices like smartphones and/or tablets for RPM enables patient mobility and provides real-time monitoring capability. The mobile device Operating System (OS) used for real-time RPM needs to meet the hard real-time requirements for alerts/alarms generation. The General Purpose OS (GPOS) uses fair scheduling algorithm for multitasking while Real Time OS (RTOS) uses preemptive scheduling. This paper evaluates the real-time performance of GPOS and a RTOS (QNX) under variety of load condition for RPM application. The results of the measurements indicate that the mobile device OS used for RPM must provide a prioritizing mechanism to satisfy the hard real-time requirements when the mobile device is multitasking and/or overloaded. |

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.
