This paper introduces Quantian, a scientific computing environment. Quantian is directly bootable from cdrom, self-configuring without user intervention, and comprises hundreds of applications, including a significant number of programs that are of immediate interest to quantitative researchers.

This paper reviews the advantages and disadvantages of traditional 5-levelGrid architecture and new OGSA standards. It also summarizes the current popular Grid resource schedule algorithms and frameworks. The paper points out the problems and trends faced by the Grid communities. It emphasizes that there must be a self-configuring Grid to support the dynamic changing complex systems. The paper ...

Alleviating poverty in small-scale fisheries requires a clear understanding of what poverty means. On the whole, different perspectives and strategies have been used to understand and address poverty. These strategies have been grounded in an understanding of poverty as a straightforward economic problem. Moreover, a number of these strategies and perspectives have one way or another been groun...

This article describes a scalable, self-configuring architecture for campus networks, the ABridges architecture. It is a two-tiered hierarchy of layer two switches in which network islands running independent rapid spanning tree protocols communicate through a core formed by island root bridges (ABridges). ABridges use AMSTP, a simplified and self configuring version of MSTP protocol, to establ...

Storage-area networks are a popular and efficient way of building large storage systems both in an enterprise environment and for multi-domain storage service providers. In both environments the network and the storage has to be configured to ensure that the data is maintained securely and can be delivered efficiently. In this paper we describe a model of mandatory security for multi-domain sto...

We present an approach for (re-)configuring the collaboration of software modules on board an autonomous device. The proposed methodology largely is based on principles of logics: Different configurations are evaluated on the fly before one configuration is chosen and applied to the system. Each configuration has its own semantical meaning that is also included in the decision process. The set ...

Scalability requirements for semantic stores lead to distributed hardwareindependent solutions to handle and analyze massive amounts of semantic data. We use a different approach by imitating the behaviour of swarm individuals to achieve this scalability. We have implemented our concept of a Self-organized Semantic Storage Service (S4) and present preliminary evaluation results in order to inve...

Self-configuring wireless sensor networks are a fascinating emerging technology: the vision is to spread out hundreds or thousands of small, cheap, battery-driven, and self-configuring nodes bearing a wireless modem to accomplish a given task jointly. An important concern is the network lifetime: as nodes run out of power, the connectivity decreases and the network can finally be partitioned an...

Configurable products are an important way to achieve mass-customisation to satisfy individual customer requirements. We describe a novel configurator prototype that supports tailoring, i.e. configuring, such a product. It contains a semi-visual modelling tool based on a high-level objectand product structure-oriented modelling language with a clear formal semantics. The main functionality is d...
