| Abstract | Civil structures are often exposed to strong winds and seismic loads resulting in large structural deflections. These undesirable deflections can be reduced by installing a structural control system within the structure. To reduce the costs associated with structural control systems, the eradication of expensive wiring required to transmit sensor data to a centralized controller is proposed. Taking advantage of decentralized control and wireless sensor network paradigms, a new approach to the design of a structural control system is presented. In this study, the feasibility of employing a wireless sensor network to both collect state-response data from sensors and to determine control forces is explored in detail. Wireless active sensing units designed to collect data from sensors, execute embedded algorithms and command actuators are adopted to serve as sensor/controller nodes within the wireless structural control system. Provided the real-time demands of the control system, wireless networks present some technological challenges (limited bandwidth, delays and loss of data packets) that must be addressed during the design of the control system. A distributed estimator framework is proposed to limit the use of the wireless communication channel leading to large-scale structural control systems with enhanced reliability. |

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.
