, they seldom make any promises about network performance, and so cloud tenants suffer from highly-variable, unpredictable network performance. Many cloud customers do want to be able to rely on network performance guarantees, and many cloud providers would like to offer (and charge for) these guarantees

surrounds the notion of “context” – what it means, what it includes, and what role it plays in interactive systems. This paper suggests that the representational stance implied by conventional interpretations of “context” misinterprets the role of context in everyday human activity, and proposes

by their skill at ordering documents. Unfortunately, the current framework as exemplified by TREC is actually dominated by ad-hoc performance and insensitive to document ordering. In this paper, we define a measure of diversity difficulty for a query and subtopics irrespective of any ranked list, and suggest

and depends more on actual comparison of one's performance with the performance of others. Thus, if a person evaluates his running ability, he will do so by comparing his time to run some distance with the times that other persons have taken. In the following pages, when we talk about evaluating

tiply connected networks: When loops are present, the network is no longer singly connected and local propaga tion schemes will invariably run into trouble . We believe there are general undiscovered theorems about the performance of belief propagation on loopy DAGs. These theo rems, which may have

theory and cultural theory, call for us to examine the implicit and explicit assumptions we make when we write about aesthetics within game studies research, as a prelude to reclaiming a perspective that will allow us to better understand the way in which games function as sites for sensory and embodied

concrete graph instances, purely in terms of the structure of the instances. In this talk, I will begin with a brief recap of such structural characterizations of query languages for structured and semi-structured data [4, 7, 8]. I will then introduce the theoretical framework we have been developing

, as well as some common criticisms, we hope to dispel some misconceptions about what constitutes a biolinguistic approach, as well as point out what we contend is real progress in the study of the biological bases and evolution of the human language faculty, to which the term is better and rightly applied
