The advent and proliferation of Service-oriented Architectures (SOA) drives computing infrastructures into a highly interconnected, heterogeneous, and dynamic world. Conventional management tools fail in the attempt to deal with the heterogeneity and the dynamics associated with this type of information infrastructures. More and more researchers try to cope with the complexity, heterogeneity, a...

Extensibility mechanisms constitute a form of knowledge capture that is essential for software re-­‐use. The Data Intensive Cyber Environments (DICE) group has collaborated with more than 25 science and engineering domains on the design of open source distributed data management systems. A major requirement has been the provision of extensibility mechanisms that enable provision of domain-­‐spe...

The notion of ad-hoc networking refers to the spontaneous formation of a network of computing nodes without reliance on a specific infrastructure. Typical ad-hoc networks consist of mobile nodes — ranging from laptops and pocket PCs to miniature sensor devices — with widely different computation and communication capabilities. Node mobility may be limited to deployment, as in the case of some s...

Fog computing aims at extending the Cloud by bringing computational power, storage and communication capabilities to the edge of the network, in support of the Internet of Things (IoT). Segmentation, distribution and adaptive deployment of services over the continuum from Things to Cloud are challenging tasks, due to the intrinsic heterogeneity, hierarchical structure and worldwide scale infras...

One of the most important design problems for multi-UAV (Unmanned Air Vehicle) systems is the communication which is crucial for cooperation and collaboration between the UAVs. If all UAVs are directly connected to an infrastructure, such as a ground base or a satellite, the communication between UAVs can be realized through the in-frastructure. However, this infrastructure based communication ...

Heterogeneous and distributed nature of the Internet makes it very diicult to customize security protocols and policies in order to satisfy the security needs of applications. Celestial network security management project addresses this issue through building an infrastructure that can dynamically set up inter-domain secure communication channels upon the requests of applications. Celestial Sys...

As the technical infrastructure to support Grid environments matures, attention must be focused on integrating such technical infrastructure with technologies to support more dynamic access to services, and ensuring that such access is appropriately monitored and secured. Such capabilities will be key in providing a safe environment that allow the creation of virtual organisations at runtime. T...

There is a growing usage of business intelligence (BI) for better management decisions in different industries. However, empirical studies on BI are still scarce. In this research we study BI from an organizational agility perspective. Organizational agility is the ability to sense and respond to market opportunities and threats with speed and BI can help the sensing part of organizational agil...

This project aims to improve the metaprogramming and verification capabilities of the GNU Compiler Collection. It consists of a plugin infrastructure that exposes two compile-time mechanisms. The first of these is a mechanism by which one may perform arbitrary computations over types within the context of the C++ template metaprogramming infrastructure. The second of these exposes selected port...
