Over the past few years, wireless mesh networks are emerging as a strong technology for cheap wireless coverage. Despite recent advances in wireless mesh networking, many research challenges remain in all protocol layers. Since a mesh network usually has very different characteristics than those of current fixed mobile networks, traditional fixed deployments such as those in cellular IP and HMIP w
This thesis consists basically of two parts. They are, however, interrelated by the fact that both parts concerns modelling of catalytic reaction systems and also by the fact that in both parts, spectral methods are used for simulation. The first part describes the numerical treatment of the dispersion model. The model is used to simulate a packed-bed reactor producing formaldehyde from methanol w
The overall aim of this paper is to examine the claim that explanation is asymmetrical because causation is asymmetrical. The link between causal and explanatory asymmetry is focussed on. It is argued that many theories of causation account for causal asymmetry in a way that stops a causal model from contributing to our understanding of explanatory asymmetry. What appears to be generally advantage

In the “sketch for a personalist aesthetic” in Le Personnalisme (1949), Emmanuel Mounier cautioned that the tendency towards abstraction in modern art was a sign of nihilism; but he also saw in it a promise to reveal a reality which transcends our habitual view of the world. To Mounier, there is a paradox in the nature of art: it is both realist and abstract; it deals with the reality of beings wh
This paper starts off with an editorial sewing circle and a patchwork seminar where participants were invited to contribute to an SMS-embroidery-feuillton by embroidering one of their own text-messages. Whereas research on participatory journalism has been based on established journalistic platforms (Karlsson 2010), this paper tries to understand the gathering, processing and publishing of informa
A personal computer program, FiFi, that makes a real-time, two-dimensional simulation of the dynamic deposition process of particles on a single fibre, has been developed. The formation of dendrites and the particle transport as a function of different parameters are simulated. The trajectory of a spherical particle as a function of external forces and diffusion is calculated by integration and th
