Open Source is a phenomenon of increasing significance for organisations, offering the prospect of effective alternative business solutions and new business opportunities. A number of surveys have been conducted in various countries with the purpose of understanding the state of practice with respect to Open Source in companies. In this paper we report on a study of the perceptions of Open Sour...

This paper deals with the problem of Blind Source Separation. Contrary to the vast majority of works, we do not assume the statistical independence betwwen sources and explicitly consider that they are dependent. We introduce three particular models of dependent sources and show that their cumulants have interesting properties. Based on these properties, we investigate the behaviour of classica...

Keynote Lecture Large-scale extracellular electrical recordings using various types of multicontact microelectrodes have become a common tool for investigating neural activity at the population level. Here we present results from several projects in our group aimed at elucidating the link between recorded extracellular potentials and the underlying neural activity. We further present several ne...

Localization of sources in patients with focal seizure has recently attracted many attentions. In the severe cases of focal seizure, there is a possibility of doing neurosurgery operation to remove the defected tissue. The prosperity of this heavy operation completely depends on the accuracy of source localization. To increase this accuracy, this paper presents a new weighted beamforming method...
