Here tree dependency structures are studied from three different perspectives: their degree variance (hubiness), the mean dependency length and the number of dependency crossings. Bounds that reveal pairwise dependencies among these three metrics are derived. Hubiness (the variance of degrees) plays a central role: the mean dependency length is bounded below by hubiness while the number of cros...

Single sensor with Bayer pattern color filters are used to reduce size and cost of consumer digital cameras. These cameras use various demosaicing algorithms to construct the entire image with true colors from the acquired insufficient RGB (Red,Green and Blue) mosaics. In order to estimate original true colors, iterative demosaicing algorithms are being employed. These algorithms incur high cos...

Falkingham concludes that these results show the importance of economic activity in the determination of dependency and in so doing they point to the inadequacy of much of the debate on retirement provision. The 1983 Green Paper on the reform of the State Earnings Related Pension Scheme (SERPS) used the argument that future higher dependency levels would be too great for the economy to bear wit...

We recorded event-related brain potentials (ERPs) during the processing of unambiguous German sentences containing different types of filler-gap dependency. Both topicalization constructions and wh-questions were found to elicit a left-anterior negativity (LAN) prior to the processing of the subcategorizing verb, relative to a gap-free control condition. At the subcategorizing verb, sentences c...

In multi-item inventory with very large number of items in retail sale stores, purchase dependency in demand amongst the items can be described by association rules mined from sale transaction data. With the knowledge of association rules, inventory replenishment policy can be designed which will result in low inventory cost and better profitability. The relevant inventory costs include the cos...

For purposes of discussion and feedback, we present a preliminary version of a simple yet powerful cost-based framework for spoken dialogue systems to continuously and incrementally decide whether to speak or not. The framework weighs the cost of producing speech in overlap against the cost of not speaking when something needs saying. Main features include a small number of parameters controlli...

This paper discusses the impact of collection cost structure on the optimal reverse channel choice in decentralized uncoordinated supply chains. Using collection cost functions that capture collection rate and collection volume dependency, we show that the optimal reverse channel choice is driven by how the cost structure moderates the manufacturer’s ability to shape the retailer’s sales and co...
