Abstract | Temperature cycling of semiconductor gas sensors is a very powerful tool for developing gas detection systems with high selectivity and stability. Microstructured gas sensors - due to their low thermal mass - have very low thermal time constants in the range of 10 ms. Based on these sensors, the development of fast and highly selective gas detection systems is possible using temperature cycles with application-specific temperature levels and an overall duration of only a few seconds. For efficient evaluation of such systems, especially in industrial applications, we have developed a flexible and low-cost hardware platform which provides accurate temperature control for arbitrary temperature profiles and fast, high resolution data acquisition either in stand-alone operation or connected to a PC. A modern MCU provides 16 bit PWM outputs which are used both for temperature control and resistance read-out. A key feature of this platform is its large effective measurement range of 26 bit resulting from a combination of 16 bit PWM with a 10 bit ADC. Based on this hardware platform, various application-specific gas detection systems either for research or industrial purposes can be realized |

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.
