Abstract | Traditional G-P algorithm exist two drawbacks in solving the correlation dimension of chaotic time series. The one is the subjective existence to determine scaleless range, the other is calculation error is large when the amount of data is small. For two shortcomings, the fuzzy C-means clustering is introduced to the G-P algorithm to determine the no-scales range. Least-squares fitting method is used to find the saturation correlation dimension value in determining the scalelesss range. Using different amount of Loren and Rossler data, such as 500, 1000, 2000, 5000 and 10000, verify the improved algorithm in this paper,. Simulation results show that the error relatively small if the delay time is small when the amount of 500, 1000 and 2000. With the length of data increases, the cluster centre value of the slope relatively flat closer to their ideal value. The conclusions are applicable to Lorenz and Rossler data. |

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.
