Item A tree based representation for effective pattern discovery from multimedia documents(Elsevier B.V., 2017) Pushpalatha, K.; Ananthanarayana, A.The growing amount of multimedia documents demanded the efficient knowledge discovery systems. The efficacy of the knowledge discovery systems is influenced by the representation of multimedia documents. The suitable multimedia document representation acts as a platform for multimedia mining tasks. In this paper, a Multimedia Suffix Tree Document model (MSTD) is presented to represent the multimedia documents in a tree based structure. The MSTD model discovers the useful patterns embedded in the multimedia documents and reduces the search time thereby aiding the multimedia mining methods. It provides the complete information of the multimedia documents in one structure. In order to evaluate the proficiency of the proposed MSTD model, the MSTD model based mining methods are proposed. The experiments are conducted with three multimodal multimedia document datasets. The experimental analysis of the proposed methods reveal the significance of MSTD representation for multimedia documents in achieving the significant performance of multimedia mining tasks. © 2016 Elsevier B.V.Item Equilibrium analysis of dual-channel supply chain under retailer's greening cost information asymmetry(IGI Global journaleditor@igi-global.com, 2020) Rofin, T.M.; Mahanty, B.The purpose of this study is to investigate the impact of information asymmetry of retailer's greening cost on the performance of both the manufacturer and the retailer. The study considers a dual-channel supply chain comprising of a manufacturer and a retailer committed to green operations. The authors have employed sequential game theoretic model to derive the closed form expressions corresponding to the two cases under consideration, that is: (1) complete information and (2) asymmetric information. They have found that the sharing of greening cost information by the retailer can make both the manufacturer and the retailer better off in terms of profit. They have also found that the greening cost information sharing is all the more important when the greening cost efficiency is weak. The study helps retail managers to make a decision on whether to conceal or reveal the greening cost information with the upstream manufacturer. © 2020 IGI Global.
