The “big elephant in the room” in the ongoing CEP dialog is that most of the current (CEP) software on the market is not capable of machine learning and statistical analysis of dynamic real-time situations. Software vendors have been promoting and selling business process automation solutions and calling this approach “CEP” when, in fact, nothing is new. There is certainly no “technology leap” in these systems, as sold today.
Most BREs today are deployed as “decision services”, and are used in “stateless” transactions to make “decisions” as a part of a business process. A CEP application is instead processing multiple event streams and sources over time, which requires a “stateful” rule service optimized for long running. This is an important distinction, as a stateful BRE for long-running processes needs to have failover support - the ability to cache its working memory for application restarting or distribution. And of course long-running processes need to be very particular over issues like memory handling - no memory leaks allowed!
Cairo will develop a tool for ingesting complex collections of born-digital materials, with basic descriptive, preservation and relationship metadata, into a preservation repository. The project is based on needs identified by the JISC-funded Paradigm project and the Wellcome Library's Digital Curation in Action project. It is a key building block in the partner institutions' strategy to develop digital repository architectures which can support the development of digital collections over the long-term.
The Rapide™ Language effort focuses on developing a new technology for building large-scale, distributed multi-language systems. This technology is based upon a new generation of computer languages, called Executable Architecture Definition Languages (EADLs), and an innovative toolset supporting the use of EADLs in evolutionary development and rigorous analysis of large-scale systems.
A successful one-week short course on Complex Systems Beyond the Metaphor: Your Mathematical Toolset was held in the UNSW School of Mathematics and Statistics on Feb 5-9, 2007. It introduced the mathematical foundations and tools needed for a solid understanding of complex systems, an area often known for purely metaphorical or 'hand-waving' explanations. Aiming at a mathematically literate audience (e.g. engineers, quantitative biologists, computer modellers), leading Australian experts presented intensive introductions to the essential topics of complex systems theory, including self-organization, nonlinear dynamical systems, cellular automata, networks and statistical learning.
The Complex Systems Registry is an Open Source federative platform that has been developed within the FET coordination action Open Network of Centres of Excellence in Complex Systems (ONCE-CS) within the framework of the Complex Systems Society.
The aims of this initiative are
* to become the main Information Hub for the Complex Systems Community,
* to offer pre-installed Web facilities to all institutions, projects, working groups, ... of the Complex Systems Community,
* to guarantee the inter-operability between all installed Web sites.
Представлен обзор результатов, идей и методов, связанных со сложными сетями. Рассмотрены две связанные проблемы:
- структурный фазовый переход в архитектуре сетей;
- переходы в кооперативных моделях сетей, как субстрат (?).
Рассмотрены эффекты самоорганизации во взаимодействующих системах в сетях.
VisualComplexity.com intends to be a unified resource space for anyone interested in the visualization of complex networks. The project's main goal is to leverage a critical understanding of different visualization methods, across a series of disciplines, as diverse as Biology, Social Networks or the World Wide Web.
