Context. Workflow management systems, crucial in sectors like healthcare and
manufacturing, require efficient task coordination while adhering to complex policies …

We present an object recognition approach using higher‐order color invariant features with
an entropy‐based similarity measure. Entropic graphs offer an unparameterized alternative …

The future brings opportunity. Large scale, distributed, digital environments offer vast
potential. Environments that are, in general, dynamic and untrusted. Within these …

This paper presents an exploration of the differences between agent-based and population-
based models for trust dynamics. This exploration is based on both a large variety of …

The book is about a very active research field in software engineering. In modern society,
the fact of the world's high reliance on software requires the system's robustness, ie …

In large-scale grid systems, plenty of applications are constrained by soft or hard deadline
requirement. However, it is difficult to guarantee the deadline requirements of these …

July 2000, a hot summer afternoon in Catania. After several hours of talking about CORBA
and Obliq, Vladimiro asked:“So, what about becoming a Ph. D., uh?”.“What'sa Ph. D.?” …

It has become increasingly popular to construct large parallel computers by connecting
many inexpensive nodes built with commercial-off-the-shelf (COTS) parts. These clusters …

Abstract Systems and methods for processing information via networked computers
leverage request handlers, process handlers, and task handlers to provide efficient …

With the increasing scale of grid systems, reliability evaluation for both grid systems and
applications become more and more challenging, especially when taking the heterogeneity …
