| Abstract | Electromagnetic interferences and other disturbances restrict the coverage area and reliability of wireless sensor networks (WSN) in industrial environment. The need for empirical data to provide evidence of these disturbances has also been addressed. This paper presents results of screening tests performed in the steam boiler process to find out the effect of some factors on jitter variation. The effect of factors is estimated from coefficients of a partial least squares model, which was fitted to on the basis of a statistical quantity calculated from jitter variation data. The quantity used, Pearson mode skewness of histogram frequencies, was selected by comparing different statistical techniques. The selected quantity seems to be able to identify some candidates for more detailed tests, namely distance from nodes to the gateway, mutual interference, sampling interval, number of nodes, frequency converter/pumping installation and the block. The results show that the effect of the single Bluetooth and WLAN transmission is insignificant compared to other factors. |

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.
