| Abstract | Tikhonov regularization is an effective way in particles size inversion of dynamic light scattering (DLS). Regularization parameter choice is the key in this approach. In order to obtain the optimal regularization parameter, according to the Morozov discrepancy principle, an regularization inversion method based on genetic algorithms (GA)is proposed. It optimizes the regularization parameter within the global region by genetic algorithms, does not require a priori particle size distribution (PSD) and doesn't also define the initial value of the regularization parameter. Computer simulations datum of particles were respectively inversed by this method. The results show that when the noise level is 0∼0.001, results of unimodal distribution particles agree with the theory distribution, and double-peak feature of bimodal distribution particles is clear, maximum error of theirs inversion peak value is less than 6.67%. Therefore, regularization inversion method with GA technique has strong immunity of noises and is feasible in particles size inversion of DLS. |

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.
