A significant trend caused by cloud computing is to aggregate applications for sharing resources. Thus, it is necessary to provide fair resources and performance among applications, especially for the network, which is provided in the best-effort manner in current clouds. Although many studies have made efforts for provisioning fair bandwidth, they are not sufficient for network fairness. In fa...

We present a proactive queue-management (PQM) algorithm called GREEN that applies knowledge of the steadystate behavior of TCP connections to intelligently and proactively drop packets, thus preventing congestion from ever occurring and ensuring a higher degree of fairness between flows. This congestion-prevention approach is in contrast to the congestionavoidance approach of traditional active...

When speech comprehension becomes effortful, e.g. in adverse conditions, it is necessary to understand which processes are the sources of the effort. By means of pupillometry, this paper investigates whether the automatic process of lexical competition increases effort, and whether mismatching cues, degradation of the signal, and listener’ experience with degraded signals additionally affect th...

INTRODUCTION During information presentation, the target audience must construct a mental representation of situations or scenarios conveyed by the verbal content and images contained in the presentation. Cognitive psychologists refer to these representations as situation models (Friedman & Miyake, 2000). During situation model construction , increases in the number of alternative order of even...
