| Abstract | Based on ant system algorithm (ASA) and 12-electrode electrical capacitance tomography (ECT) system, a new method is proposed for the on-line voidage measurement of oil-gas two-phase flow. The ASA is adopted to select the effective capacitance set (the capacitances in this set make significant contributions to the voidage measurement) from 66 measurement capacitances obtained from the ECT system and determine its contribution weight vector. The practical voidage measurement process includes three steps. Firstly, 66 measurement capacitances are obtained and the real-time flow pattern of the oil-gas two-phase flow is identified. Secondly, the effective capacitance set and its contribution weight vector are determined by using the ASA, and an appropriate voidage measurement model is chosen according to the flow pattern identification result. Finally, the measurement voidage value is calculated. Experimental results show that the proposed voidage measurement method is effective. The real-time performance and measurement accuracy are satisfactory |

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.
