Technology Readiness Levels (TRLs) have been available for more than 25 years, first developed by the National Aeronautics and Space Administration (NASA) to ensure appropriate technology was reliable enough to be integrated into space systems. The Department of Defense (DoD) now requires their use in assessing both complex weapon system Critical Technology Elements (CTEs) and overarching program...
In digital ecosystems, where they are no central authorities or single points of failure or control, entities form dynamic relationships to facilitate transactions and knowledge sharing. These relationships are contextual, evolving and not subject to central moderation. The devolved structure of these emergent environments pose unique challenges for identity. In this paper, we build on previous work...
Successful uptake of digital ecosystems requires trust in the underlying platform and in the users of that platform. Accountability mechanisms provide a basis for creating, monitoring and evolving trust. This work analyses the requirements for accountability in digital ecosystems and proposes an accountability model for deployment of digital ecosystems in peer-to-peer networks.
There is a need for exchange and trade of contextual information within ubiquitous computing environments between different providers of context-aware services. It is the need of a mobile user to obtain such services wherever he roams during the course of the day, such as home, workplace, leisure and visiting businesses, in a way that is safe and secure for both the user as well as the providers,...
The aim of this paper is to discuss the legal and technical issues of creating legally binding contracts in a digital ecosystem and to present the solution created for the DBE (Digital Business Ecosystem) project. We investigate the legal implications of electronic contracts and digital signatures, and also take a brief look at the types of clauses that make up a contract. The DBE contract model for...
As the progress in biology and medical science, especially in DNA technology, large amounts of biomedical data continue to grow inexorably in size, dimension and complexity. We need to develop more scalable and more efficient techniques and methods to analyze and represent the large and high-dimensional biomedical data sets. Formal concept analysis (FCA) is an effective tool for data analysis and...
We present a framework enabling charging for composed services comprised of services offered by multiple providers. In the framework rating engines may generate charge information for individual services and provide this information upon request to other rating engines when these services are used as part of a composed service. Rating engines additionally employ a two-phase rating process which allows...
The national need for scientists and engineers and for a public that understands science and technology is more urgent today than ever before if the United States is to maintain its productivity and technical edge in the world market. Many capable high school students, however, lose interest in pursuing scientific academic subjects and in considering science or engineering as a possible career. An...
