When a monkey searches for a colour and orientation feature conjunction target, the scan path is guided to target coloured locations in preference to locations containing the target orientation [Vision Res. 38 (1998b) 1805]. An active vision model, using biased competition, is able to replicate this behaviour. As object-based attention develops in extrastriate cortex, featural information is pa...

Representational views of the mind traditionally face a skeptical challenge on perceptual knowledge: if our experience of the world is mediated by representations built upon perceptual inputs, how can we be certain that our representations are accurate and our perceptual apparatus reliable? J. J. Gibson's ecological approach provides an alternative framework, according to which direct perceptio...

We introduce a new notion in self-assembly, that of transforming the dynamics of assembly. This notion allows us to have transformation of the plane computed within the assembly process. More specifically, we study a zooming transformation. First we show that the possibility of doing that transformation depends on the regularity of the assembly process, as expressed by the order condition. Then...

Self-adaptivity allows software systems to autonomously adjust their behavior during run-time to reduce the cost complexities caused by manual maintenance. In this paper, an approach for building an external adaptation engine for self-adaptive software systems is proposed. In order to improve the quality of selfadaptive software systems, this research addresses two challenges in self-adaptive s...

Abstract: Today, most peer-to-peer networks are specialised for sharing files, mostly video and audio files. In this paper we describe a peer-to-peer network we are currently implementing. It connects webcams and allows users to search for online pictures and video-/audiostreams by keyword and by location. Peer-to-peer technology is used for the self-organising network so that no central servic...

The Pattern self-Assembly Tile set Synthesis (PATS) problem, which arises in the theory of structured DNA self-assembly, is to determine a set of coloured tiles that, starting from a bordering seed structure, self-assembles to a given rectangular colour pattern. The task of finding minimum-size tile sets is known to be NP-hard. We explore several complete and incomplete search techniques for fi...

Model sets (also called cut and project sets) are generalizations of lattices, and multi-component model sets are generalizations of lattices with colourings. In this paper, we study self-similarities of multi-component model sets. The main point may be simply summarized: whenever there is a self-similarity, there are also naturally related density functions. As in the case of ordinary model se...

Self-organization is the process where a structure or pattern appears in a system without a central authority or external element imposing it through planning. In various areas, simulation is a safe and low-cost alternative to complex problems. We developed a free online simulation tool which computes and displays spatial self-organizing behavior of individuals in a stepping stone environment.
