Enterprises want to improve the lifecycle support for their businesses processes by modeling, enacting and monitoring them based on process management systems (PrMS). Since business processes tend to change over time, process evolution support is needed. While process evolution is well understood in traditional activitycentric PrMS, it has been neglected in object-aware PrMS so far. Due to the ...

Data Stream Management Systems (DSMSs) do not statically respond to issued queries — rather, they continuously produce result streams to standing queries, and often operate in a context where any interruption can lead to data loss. Support for schema evolution in continuous query processing is currently unaddressed. In this work we address evolution in DSMSs by proposing semantics for three evo...

A long-standing conjecture is that winner-take-all games such as patent races lead to the survival of risk-takers and the extinction of risk-averters. In many species a winner-take-all game determines the males' right to reproduce, and the same argument suggests that males will evolve to be risk-takers. Psychological and sociological evidence buttresses the argument that males are more risk-tak...

Work on architecture-centred software development has been undertaken during the past years, leading to the proposition of architecture description languages with high expression power. The concerns that are focused on lately are related to the impact these new approach may have on the software evolution management, namely the possibility of extending the evolution issues to earlier development...

This chapter summarizes analytic theory and numerical calculations for the formation and collisional evolution of KBOs at 20–150 AU. We describe the main predictions of a baseline self-stirring model and show how dynamical perturbations from a stellar flyby or stirring by a giant planet modify the evolution. Although robust comparisons between observations and theory require better KBO statisti...

Process management concepts have been present within the modern organizational development since its early days. Since then, we have been able to detect many changes, challenges and improvements that occurred in the field during the past century with the primary aim remaining unchanged: defining and optimizing organizational processes in order to achieve better business results. This paper disc...
