The Scaling Phenomena
Scaling behaviour is observed in many elds and its ubiquity has been amply witnessed in telecommunications traac data. Whereas the notion of scaling can be attached to diierent features such as self-similarity, long-range dependence or (multi-)fractality, it leads in all cases to challenging problems in terms of analysis, estimation and synthesis. These issues are addressed here by using the na...
متن کاملAccuracy and scaling phenomena in Internet mapping.
It was recently argued that sampling a network by traversing it with paths from a small number of sources, as with traceroutes on the Internet, creates a fundamental bias in observed topological features like the degree distribution. We examine this bias analytically and experimentally. For Erdo s-Re nyi random graphs with mean degree c, we show analytically that such sampling gives an observed...
متن کاملFluctuations and scaling in aggregation phenomena
Many physical phenomena are governed by the aggregation of material. Such processes have been studied in earnest since the early parts of this century and continue to attract considerable interest within areas that range from astrophysics 2 to biology. The most powerful methods for analyzing these phenomena are based on general scaling arguments 5 applied to the number and size distribut...
متن کاملFracture Mechanics and Corrosion Fatigue
The development and current state-of-the-art in fracture mechanics in relation to studies of environment-enhanced fatigue-crack growth (corrosion fatigue) and fatigue-crack growth per se are reviewed. Patterns of response of materials to different loading and environmental conditions are considered in terms of the probable mechanisms for environmental embrittlement. The usefulness of the fractu...
متن کاملFatigue fracture of hydrogels
Rapid advances are taking place to develop hydrogels of high stretchability and toughness, but fatigue fracture has not been studied for any hydrogels. This negligence hinders the development of hydrogels and their applications. Herewe initiate a study of fatigue fracture of hydrogels.We choose polyacrylamide hydrogel as a model material. To place fatigue fracture in context, we apply monotonic...
