It has been widely recognized that the performance of a multi-agent system (MAS) is highly affected by its organization. A large scale MAS may have billions of possible ways of organization, depending on the number of agents, the roles, and the relationships among these agents. These characteristics make it impractical to find an optimal choice of organization using exhaustive search methods. I...

In this paper we present results from an ongoing controller comparison study at the National Renewable Energy Laboratory’s (NREL’s) National Wind Technology Center (NWTC). The intention of the study is to demonstrate the advantage of using modern multivariable methods for designing control systems for wind turbines versus conventional approaches. We will demonstrate the advantages through field...

The characteristics of self-organising, adaptive systems (SOAS) lead to a signi cantly higher exibility and robustness against an ever-changing environment. This exibility makes it hard to test these systems adequately, which is, however, inevitable in order to assure their quality. As a part of our vision of testing SOAS, we present a framework for testing selforganisation (SO) algorithms. The...

Study of the baking of biscuits involves among other aspects detailed analysis of colour changes in the product during the process. Previous study has shown the existence of a colour development curve (known as the baking curve) by examining colour development in the RGB and HSI colour spaces. In the current work a diierent approach to extracting the baking curve is presented. Using a Kohonen s...

This paper analyses research evidence about the creative environments in the UK television production sector. The industry is reviewed across a number of dimensions: the evolving sentiments and structures of collective creativity; the perception of the actual and the ideal creative environment for television production; the growing levels of uncertainty associated with freelance work; and the k...

Ancient Greek literature gives us many relevant traces of the way people represented maritime spaces. Greek narratives endow these spaces with meaning and make them legible. Indeed, these testimonies are a significant contribution to our knowledge of the “odological” space at sea, a space of description including numerous cultural features rather than a space described. This space is based on e...

This paper presents a novel unsupervised sensor fusion method to detect artificial objects in outdoor environments. We define artificial objects present in outdoor environments using structure and appearance informations: an artificial object is composed of several smooth surfaces with sufficiently extended area and distinctive color from the surrounding environment. The structure information d...

It has been widely recognized that the performance of a multi-agent system is highly affected by its organization. A large scale system may have billions of possible ways of organization, which makes it impractical to find an optimal choice of organization using exhaustive search methods. In this paper, we propose a genetic algorithm aided optimization scheme for designing hierarchical structur...

This paper introduces a new concept to the processing of graph structured information using self organising map framework. Previous approaches to this problem were limited to the processing of bounded graphs. The computational complexity of such methods grows rapidly with the level of connectivity, and are restricted to the processing of positional graphs. The concept proposed in this paper add...
