This paper proposes a new adaptive extended Kalman filter (AEKF) for a class of nonlinear systems perturbed by noise which is not necessarily additive. The proposed filter is adaptive against the uncertainty in the process and measurement noise covariances. This is accomplished by deriving two recursive updating rules for the noise covariances, these rules are easy to implement and reduce the n...

The extended piano(s), the body(ies) is an ongoing research project on piano as instrument started in 2014 by pianist and composer Hara Alonso. Over years, it has been developed different directions forms ranging from composition, improvisation installation. questions are: How can we rethink beyond its history technology? expand incorporating embodied composition methods? This intends to develo...

It’s a pleasure to contribute this paper to Andy Clark and his Critics. Andy has been an influential figure for me ever since I read his first book Microcognition while I was in graduate school. A few years later I took up my first job as a post-doctoral fellow working with him in the newly initiated Philosophy-Neuroscience-Psychology program at Washington University in St Louis. We had a lot o...

Phenotype, whether conventional or extended, is defined as a reflection of an underlying genotype. Adaptation and the natural selection that follows from it depends upon a progressively harmonious fit between phenotype and environment. There is in Richard Dawkins’ notion of the extended phenotype a paradox that seems to undercut conventional views of adaptation, natural selection and adaptation...
