Fast Algorithms for Sequence Pattern Recognition in Massive Datasets D. Gunaseelan Sequential Pattern Mining is the process of applying data mining techniques to a sequential database for the purpose of discovering the correlation relationships that exist among an ordered list of events. The patterns can be used to focus on the retailing industry, including attached mailing, add-on sales and customer satisfaction. In this vaper, I present fast and efficient algorithms called AprioriAllSID and GSPSID for mining sequential patterns that are fundamentally different from known algorithms like Apriori All and GSP (Generalized Sequential Patterns). The algorithm has been implemented on an experimental basis and its performance studied. The performance study shows that the proposed algorithms have an excellent performance over the best existing algorithms.

Histopathalogy of Procamallanous lonis ( Yamaguti ,1935) from economically important fin fish within Batticaloa lagoon. Sujaraini. V, Vinobaba. P Procamallanus lonis (Family Camallaidae) infecting Siganus sp. at higher prevalences was found to cause growth retardation. This study, therefore, focused principally on the histopathology caused by the above parasite on a population of Siganus from the Batticaloa Lagoon. The inflammatory response of the host provides sufficient clues to the pathogenicity of this parasite on economically important host; these are tissue invading parasites are more pathogenic rather than merely being intestine inhabiting parasites. The infections of Procamallanus lonis in Siganus sp., Glossogobious giuris, Tachysurus sp. and Ompak bimaculatus were studied to assess their pathological effect. Infected tissue samples, notably from the intestine, liver and kidney were fixed in 10% formalin and processed for wax embedding. All tissues were cassetted, labeled and processed for histological sectioning. Five micrometre thick sections were cut and stained with haematoxlin and eosin. In the intestine infections elicited an inflammatory response leading to a light epitheloid encapsulation of the parasite. The encysted parasite causing pressure changes to the surrounding tissue. Heavy nematode infections were accompanied by hypertrophy of the tissue and the formation of a hyper plastic tissue reaction. Suchmarked tissue reactions may alter the absorptive nature of the intestine and presumably, the health condition of the host.
