To offer online bundles of independent e-services, software is needed that composes services of different enterprises into a bundle of services, satisfying a complex consumer need. In earlier research, a service ontology – a formalized conceptual model of services – has been developed for such software-aided service bundling. This ontology, however, did not include constructs to reason about th...

Situational method for satisfying organisation configuration definitions has become an important activity for many modern organisations. In the last few decades many situational method models have been developed but no model has proved to be successful at effectively deliver the customized light-weight methods fulfilling the organisation requirements. The paper introduces an Agile Method engine...

In the product family based application engineering process configuration of the reusable assets is an important issue. Variability introduced during domain engineering has to be resolved to the concrete requirements of the specific application. On the requirements level variability is typically described in feature models as introduced in the FODA approach. On lower levels variability is integ...

When developing applications based on business objects and processes it is important to address two important factors: requirements for change so that business information systems can evolve over time and the linking of business objects with legacy information systems. The common aim of these two requirements is the ability to smoothly combine modern and legacy business components within a runn...

The Windows 2000 operating system brought considerable changes to the capabilities and configuration options of the I/O subsystem over those available with the Windows NT operating system. This paper will cover, in terms of impact on performance, the options available for configuring this very critical component of Windows 2000. We will describe the available choices at each layer of processing...

As Ethernet PON (EPON) systems move into mass deployment, Service Providers have begun in earnest to explore the utility of this technology for delivering services other than best-effort Ethernet transport. Adding these new services, which commonly include telephony, video delivery, and leasedline transport, have the potential of increasing substantially the revenue generated by an EPON deploym...

A mechanistic view of software component assembly implies exact matching and fitting of the particular components. We argue that components for large-scale software construction should have automatic configuration capabilities in order to significantly enhance their reusability and maintainabilty. The paper sketches a pragmatic approach for implementing selfconfiguring components, relying on fr...

Archival storage systems must operate under stringent requirements, providing 100% availability while guaranteeing that data will not be lost. In this paper we explore the multiple interconnected subsystems that must be tuned to simultaneously provide high data transfer rates, high transaction rates, and guaranteed meta-data backup. We examine how resources must be allocated to the subsystems t...

We demonstrate how to develop Web-based user interfaces for Semantic Web applications using commonly available, off-the-shelf Web widget libraries. By formally defining the underlying data model that is assumed by these widgets, Semantic Web application developers can use familiar RDF constructs to map their own data to the model implemented by the Widgets. As an example, we briefly describe th...

The following casestudy provides a workflow perspective on the Grid ENabled Integrated Earth systemmodelling (GENIE) framework, which was introduced in Vol. 1. The three aims in constructing the framework were; (i) the flexible coupling of Earth system components; (ii) to tune and run the resulting models on a wide variety of platforms, including the Grid; and (iii) to archive, query and retrie...
