Automatic forest fire detection with CCD cameras requires a landscape image analysis in two stages: first the tracking of local dynamic envelopes of pixels, and second the discrimination between the various natural phenomena that may cause such envelopes. For this second process, we have to deal with restrictive conditions: lack of spatial information,(More)
One of the most convincing explanations papers generally provide concerning clusters in knowledge-based economies refers to the geographically bounded dimension of knowledge spillovers. Here, we shall underline that location decision externalities precede local knowledge spillovers in the explanation of cluster aggregate efficiency, which thus requires us(More)
The paper develops an evolutionary framework of regional resilience with a primary focus on the structural properties of local knowledge networks. After a presentation of the network-based rationales of growth and structuring of clusters, we analyze under which structural conditions a regional cluster can mix short run competitiveness without compromising(More)
First cry has been much studied especially from an acoustical point of view. However, the mechanisms of sound production are unclear. Thus, following studies we previously performed, we extend in this present work our simulations to a more realistic geometry obtained by MRI images of a fetal larynx. This work confirms the major role of vortices and may be(More)
the striking variety of the knowledge processes that are described in EURODITE TKDs need to be classified according to the identification of a limited set of regional patterns that typify their features. Among these key parameters, the papers focuses on the balance and the trade-off between proximity and distant relations, with for our concern, a particular(More)
