| Abstract | This paper presents the digital signal processing architecture of a 2D cylindrical ultrasonic phased array, with capability of electronic scanning and 3D beam steering, which can be used for NDE applications in several fields: oil and gas industry, water distribution, sub-sea applications, etc. The processing architecture (called AMPLIA) is specifically designed for embedded ultrasonic 2D array applications, and it is able to support array transducers composed by thousands of elements. Based on standard FPGA technology, it can be defined as a modular, parallel and pipelined architecture. In combination with sigma-delta converters it provides a high degree of integration. AMPLIA is organized around a pipe-line bus that integrates a set of modules for analog and digital processing. All the structure is commanded by a special module called Interface and Control Unit (ICU). This modular configuration provides flexibility to fulfil a wide range of application requirements. A high performance with a sustained processing throughput of 40 MSamples/s is achieved. A specific application consisting on a cylindrical array with 800 elements (10 rows of 80 elements each) with capability for 3D beamforming is presented. Real time imaging and low volume are the main requirements of this system |

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.
