The investigators acquired laboratory equipment to establish Secure Wireless Ad-hoc Networking (SWAN) laboratory with wireless sensor and ad-hoc network capabilities consisting of laptops and MICA2 motes. We are currently working to develop efficient protocols in sensor and ad-hoc networks to address node position identification, cross-layered MAC, reliable data communication, and enhancing the...

UDDI is not suitable for handling semantic markups for Web services due to its flat data model and limited search capabilities. In this paper, we introduce an approach to allow for support of semantic service descriptions and queries using registries that conforms to UDDI V3 specification. Specifically, we discuss how to store complex semantic markups in the UDDI data model and use that informa...

We present an approach for generating implementations of abstraction layers implementing the communication infrastructure of applications modeled as process networks. Our approach is unique in that it does not rely on assumptions about the capabilities and topology of the underlying platform. Instead, a generic implementation is adapted to the particular platform based on information retrieved ...

Today’s turbulent environment increases the degree of uncertainty organizations can experience. Organizations differentiate and develop a repertoire of competencies to respond to, and to influence this environment. The degree to which organizations can respond to the competing demands is a measure of an organization’s strategic flexibility. The business imperative of strategic flexibility is po...

One of the major problems large metropolitan areas have been facing is traffic congestion (saturation of the transportation network infrastructure). The problem’s cause is well-known: as demand gets higher, the infrastructure (roads, rails and so on) is unable to fulfil it, because of its limited capacity. The alternative to the permanent enlarging of the infrastructure is to make use of more e...

The US National Science Foundation (NSF) SI2-funded LAPPS Grid project has developed an open-source platform for enabling complex analyses while hiding complexities associated with underlying infrastructure, that can be accessed through a web interface, deployed on any Unix system, or run from the cloud. It provides sophisticated tool integration and history capabilities, a workflow system for ...

Capabilities and their underlying knowledge assets represent a major competitive resource for knowledge-intensive organisations such as e-businesses. The research presented in this paper utilises a series of case studies to identify the key knowledge assets for e-businesses. The paper suggests the Knowledge Assets Map as a framework to identify and manage key capabilities and key assets in toda...

The paper describes a comprehensive approach for the modelling and description of technologies available within a European Research Infrastructure consisting of distributed research infrastructures all over Europe. The resulting knowledge management system integrates the partial approaches of several European research activities in this area to a comprehensive description format for technical c...

• Allow autonomous partners to advertise their terms and capabilities, and engage in peer-to-peer interactions with any other partners • Web services: self-described and autonomous software entities, can be published, discovered, and invoked over the Internet (using XML-based standard languages and protocols) • Resource virtualization, infrastructure simplification and consolidation • On demand...

Service Innovations are an opportune strategy for companies to compete in the digital age and to transform their business models taking a service perspective on their value creation. Digital business models require unique value propositions that incorporate digital technologies. Companies are required to build new digital capabilities to design and implement digital strategies. The paper takes ...
