Near-optimal gossiping algorithms are given for two-dimensional and higher dimensional tori, assuming the full-port store-and-forward communication model. For two-dimensional tori, a previous algorithm achieved optimality in an intricate way, with an adaptive routing pattern. In contrast, the processing units in our algorithm forward the received packets always in the same way. We thus achieve ...

Recent revelations that ISPs selectively manipulate P2P traffic have sparked much public discussion. Underlying this issue is the misalignment of interests between consumers on one hand who desire bulk transfers at flat rates, and ISPs on the other hand who are bound by budget and capacity constraints. Our thesis is that much of the tension can be alleviated by time-shifting traffic away from p...

business all around the world uses different approaches to know their customers, segment them and formulate suitable strategies for them. one of these approaches is calculating the value of each customer for the company. in this paper by calculating customer lifetime value (clv) for individual customers of an online toy store named alakdolak, three customer segments are extracted. the level of ...

Do store brands aid store loyalty by enhancing store differentiation or merely draw price sensitive customers with little or no store loyalty? This paper seeks to answer the question by empirically investigating the relationship between store brand loyalty and store loyalty. First, we find a robust monotonic positive relationship between store brand loyalty and store loyalty using multiple loya...

Purpose: This research investigates role of store brands as a time and money saving heuristic in the context of an omnipresent store brand hierarchy. Drawing on the work of Tversky and Kahneman (1982) it proposes that the store brand hierarchy is characterised by many of the traits of frequently used heuristics employed by grocery shoppers. Design/methodology/approach: Based on Chaiken’s (1980)...

We compare and contrast two formal approaches for system development: state-based notation with veriication by deductive reasoning, exempli-ed here by action systems; and event-based notation with veriication by model checking, here using CSP/FDR. Our purpose is to identify spe-ciic similarities and diierences, and strengths and weaknesses of the two approaches by direct comparison on the same ...
