| Abstract | The high reliability and long life characteristics of electronic products result in long degradation test time and low efficiency. Traditional degradation test depends on priori information and statistical analysis method is complex. In view of those problems, an evaluation method of step-down stress accelerated degradation modeling based on Gamma process is proposed. Firstly, the degradation path is portrayed by a Gamma process. Then using the Gamma process characteristics and MCMC method, the parameters are evaluated. this method greatly simplifies the procedure of statistical analysis. Finally, the simulation of metallized film capacitors is provided, the assessment of step-down stress is compared with constant stress and step-up stress, the validity and the efficiency of the proposed method is presented. |

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.
