with a layered transmission system. By selectively forwarding subsets of layers at constrained network links, each user receives the best quality signal that the network can deliver. We and others have proposed that selective-forwarding be carried out using multiple IP-Multicast groups where each

Mobile users' data rate and quality of service are limited by the fact that, within the duration of any given call, they experience severe variations in signal attenuation, thereby necessitating the use of some type of diversity. In this two-part paper, we propose a new form of spatial

Clustering data by identifying a subset of representative examples is important for processing sensory signals and detecting patterns in data. Such “exemplars ” can be found by randomly choosing an initial subset of data points and then iteratively refining it, but this works well only

Abstract—Mobile users ’ data rate and quality of service are limited by the fact that, within the duration of any given call, they experience severe variations in signal attenuation, thereby necessitating the use of some type of diversity. In this two-part paper, we propose a new form of spatial

efficient implementation are presented in full detail; an extension to color-image denoising is also developed. The experimental results demonstrate that this computationally scalable algorithm achieves state-of-the-art denoising performance in terms of both peak signal-to-noise ratio and subjective visual

We consider a market-for-lemons model where the seller is a price setter, and, in addition to observing the price, the buyer receives a private noisy signal of the product’s quality, such as when a prospective buyer looks at a car or house for sale, or when an employer interviews a job candidate

Purpose – The goal of this article is to demonstrate how signaling support services and contractual arrangements that create value for incumbent franchisees can help to create value for the whole network by attracting prospective franchisees. Design/methodology/approach- Using data from Bond’s

submicron fabrication technologies present new reliability challenges in the form of degraded signal quality and logic failures caused by natural radiation interference. In this paper; we introduce dynamic verification, a novel microarchitectural technique that can significantly reduce the burden

Internet auction companies have developed innovative tools that enable sellers to reveal more information about their credibility and product quality to avoid the “lemons ” problem. On the basis of signaling and auction theories, the authors propose a typology of Internet auction quality
