in this paper, we give a characterization of strongly jordan zero-product preserving maps on normed algebras as a generalization of  jordan zero-product preserving maps. in this direction, we give some illustrative examples to show that the notions of strongly zero-product preserving maps and strongly jordan zero-product preserving maps are completely different. also, we prove that the direct p...

let g be a simple connected graph. the generalized polarity wiener index ofg is defined as the number of unordered pairs of vertices of g whosedistance is k. some formulas are obtained for computing the generalizedpolarity wiener index of the cartesian product and the tensor product ofgraphs in this article.

The purpose of this study is to review the Lean tool application and its utilisation in medical device design new product introduction process establish benefits best practices for integration with existing processes. A literature on current state New Product Introduction (NPI) processes completed along a comprehensive history development NPI. indicates that can be combined predominant NPI exec...

We obtain the optimal pricing policy of a monopolist marketing successive generations of product advances. We characterize the impact of foresight regarding entry of the second generation product and the technological substitution and market expansion created by the introduction of the second generation product on the optimal pricing policy of the monopolist. We also obtain the optimal pricing ...

In the South Korean cigarette market, consumers have shown dramatic changes in their cigarette preferences. While most consumers smoked high-tar cigarettes ten years ago, now most consumers prefer low-tar cigarettes. Another interesting trend in this market is the growing popularity of super-slim cigarettes. Given the strong dynamics in preferences, I raise two critical questions – 1) what are ...

We describe the introduction of Lotus SametimeTM, an instant messaging (IM) product, in an organization. This brief report analyzes the development of several aspects of user experience over a 24-month period: (1) savings in the use of other communication channels, (2) growth in messaging behaviors, (3) change in messaging partners, and (4) beliefs about the value of the product. Although IM is...
