The explosion of multimedia digital content and the development of technologies that go beyond traditional broadcast and TV have rendered access to such content important for all end-users of these technologies. While originally developed for providing access to multimedia digital libraries, video search technologies assume now a more demanding role. In this paper, we attempt to shed light onto...

Quantum-dot cellular automata (QCA) are an emerging technology and a possible alternative for semiconductor transistor based technologies. A novel fault-tolerant QCA full-adder cell is proposed: This component is simple in structure and suitable for designing fault-tolerant QCA circuits. The redundant version of QCA full-adder cell is powerful in terms of implementing robust digital functions. ...

Quantum-dot cellular automata (QCA) are an emerging technology and a possible alternative for faster speed, smaller size, and low power consumption than semiconductor transistor based technologies. Previously, adder designs based on conventional designs were examined for implementation with QCA technology. This paper utilizes the QCA characteristics to design a fault-tolerant adder that is more...

This paper empirically explores the concept of co-materialization to explain the digital innovation dynamics in offshore petroleum production. The central insight developed is that the very nature of subsurface processes and phenomena that may be monitored and controlled is transformed as offshore petroleum production is digitalized. The paper shows how digital technologies are intrinsic to thi...

In an attempt to qualify technologies that may assist bridge the digital divide, this paper examines the relationship between the digital divide and different current technologies as well as the up-to-date status of the digital gap in Africa using statistics provided by the International Telecommunication Unit (ITU). Looking at this imbalance of accessing information and communication technolog...

Digital heritage technologies are radically changing the way we engage with material culture and are negotiating new ways of knowing and understanding the object. Realising the importance of digital technologies and new interdisciplinary possibilities, the E-curator project has been undertaken by UCL Museums and Collections with the goal of applying two state of the art digital technologies: 3D...
