This paper focuses on agent-based approach to study the relationship between the individual behavior of participants and the overall development of a virtual community, to help pe...
In this paper we introduce GPU particle tracing for the visualization of 3D diffusion tensor fields. For about half a million particles, reconstruction of diffusion directions fr...
Building conversation protocols has traditionally been an art more than a science, as their construction is often guided by designers’ intuition rather than by a principled appro...
In a joint research project concerning the use and design of IT in public services, we are using a simple figure of on-going design-oriented interactions to highlight shifting foc...
We present a new adaptive fast multipole algorithm and its parallel implementation. The algorithm is kernel-independent in the sense that the evaluation of pairwise interactions do...
