We propose statistically self-similar and rotation-invariant models for vector fields, study some of the more significant properties of these models, and suggest algorithms and methods for reconstructing vector fields from numerical observations, using the ...
We investigate the intra-organizational antecedents of firm-level absorptive capacity (AC). Specifically, we examine how the functional areas of R&D, manufacturing and marketing contribute to the absorption of knowledge coming from different external knowl ...
Since the past decades, the postal sector is undergoing profound reform (liberalization). The major motivation for such reform processes was and still is the belief that liberalization and deregulation stimulates, among others, product and process innovati ...
We construct a model of innovation diffusion that incorporates a spatial component into a classical imitation-innovation dynamics first introduced by F. Bass. Relevant for situations where the imitation process explicitly depends on the spatial proximity b ...
This paper extends the line of research attempting to link innovation to economic growth by addressing some unexplored questions Using global patent data this paper empirically investigates the importance of both the quantity and quality of innovation on e ...
In a network industry like railways, major systemic innovations and new technological trajectories are tightly connected to national institutional frameworks and policies. The major transformation occurring in Europe brought by the liberalization and harmo ...

Although we need to continue our efforts in basic sciences and research for the discovery of fundamental knowledge, we also need to focus on how this knowledge can improve human health. Often, it is not a single view or approach that will lead to discoveri ...
The European railway sector has undergone major transformations over the past two decades. Domestic reforms have been buttressed by European directives aimed at creating a single European railway market. In this new environment roles have been significantl ...
We describe a new approach to speech recognition, in which all Hidden Markov Model (HMM) states share the same Gaussian Mixture Model (GMM) structure with the same number of Gaussians in each state. The model is defined by vectors associated with each stat ...
