Abstract Extensive research has been carried out in the last two decades about the users’ search query and behaviour. Many systems have been formulated based on the search query pattern with learning and modelling and providing prediction about the possible growth in search patterns. They are dependent on the statistical methods which use logs and these logs are mined using tools.... Extensive research has been carried out in the last two decades about the users’ search query and behaviour. Many systems have been formulated based on the search query pattern with learning and modelling and providing prediction about the possible growth in search patterns. They are dependent on the statistical methods which use logs and these logs are mined using tools. In this research we relied on the tracking the individual user search pattern for query formulation and use the Petri Nets for understanding the search pattern models. Read More Read Less

Abstract We have used the stochastic modelling and discrete event simulations with the use of particular metrics and performed the e-commerce systems. We have deployed two models the one used the single module for common configuration and another with spare module. Finally, we have made comparative studies for about the two used configurations....

High performance computing is a preferred area of study in computing which has potential impact in the future computing and hence using many approaches, the studies have been carried out. In the first approach a cluster of systems linked in LAN is used to bring a single system. In the second one in the grid system, a union of many computer resources are linked in multiple locations. When using the data flow approach, the issues are solved, while the von Nuemann principles is found to be less effective. Easily accessible dataflow engines have given ideas to advocate the developments. We in this work analysed the existing many approaches on high performance computing with the special observation about the dataflow use in the HPC. Read More Read Less
