Perspectives on Mature Marshallian Industrial Districts
No full textIndustrial districts growing in various industrialized countries and regions after the golden age of mass production, in the second half of the twentieth century, have shown a re-emergence of forces of local development. The success stories, in particular those more peculiar and consistent as forms of industrial and social organization, like many Italian cases, have asked and favored the definition of apposite concepts and frames of interpretations. A strong basis of theoretical refinement was extracted from Alfred Marshall’s reflections on the role and working of industrial districts before the golden age of mass production. A well-known refinement is the model of the so-called Marshallian industrial district (MID). Sustained trajectories of success gravitating around the logic of such model have resulted in what may be intended as cases of typical mature industrial districts. They have been confronting since the end of the last century with the effects of a new wave of globalization challenges. It is argued in this paper that MID general structural and dynamic characters encompass a large set of empirical cases, in particular those of typical mature IDs reacting progressively, in terms of innovation and internationalization, to contemporary challenges and de-maturing. They find their way and combine old and new characters, still within the model. However, the MID’s borders may be trespassed as well, as the MID logic coalesces with other logics of industrial and social organization.Marshallian industrial districts; contemporary innovation and internationalization challenges
Towards a framework for the evaluation of policies of cluster upgrading and innovation
No full textIn the current scenario, a large and growing number of policies for local development and cluster upgrading explicitly incorporate the idea of innovation as a systemic process, embedded in specific socio-cultural and institutional contexts and intermingled with international challenges, opportunities, and strategies. These policies bring new challenges to the activities of analysis and evaluation: despite the diffusion of a systemic approach both in innovation thinking and in innovation policies, a proper system-based framework for the analysis and evaluation of these policies is far from being achieved (Bellandi and Caloffi, 2010). Trying to advance our reflection on this field, we propose some exemplifications on a quite delimited set of contexts, i.e. those of industrial districts (Italian, in particular), characterized by SMEs clusters facing contemporary globalization challenges. Focusing on innovation policies aimed at supporting functional upgrading of districts and clusters soaked in changing international filières and value chains, the paper discusses the meaning of evaluation of industrial policies when a systemic perspective is considered. On such premises a couple of exemplifications are illustrate some features of appropriate evaluation methods. Finally, some methodological aspects concerning the design process of evaluation activities are discussed.Evaluation of policies; systemic approaches to evaluation; innovation and cluster policies; industrial districts
Automatic 3D facial fitting for tracking in video sequence
No full textThis chapter presents the 3D face model initialization procedure. The major contribution is the innovative coarse-to-fine 3D initialization strategy proposed that deals with common problems of errors in feature selection process and with a lack of features points. The proposed approach is based over 3D deformable tracking system.We also propose a deep adaptation strategy while tracking for dealing with difference between real face mesh and the model ones. The 3D refinement proposed (also the deep one) are robust to initial light situation and expression

The Feynman-like Procedure Of Ordered Exponential Operators Applied To Solar Neutrinos
No full textAn analytic resonant solution to the solar neutrino problem induced by small solar magnetic field phase velocity is derived using the Feynman-like procedure of ordered exponential operators. We assume the standard solar model matter distribution inside the Sun and the model proposed by Akhmedov and Bychuk for the solar magnetic field to conclude that a neutrino magnetic moment of order (5-8)×10-13μB is sufficient to explain the experimentally observed solar neutrino deficit, an improvement by a factor (2-4) relative to the conventional resonant spin-precession solution induced by neutrino squared mass difference when the same solar characteristics are considered. © 1993.31701/02/15130136Davis, (1990) Proc. of the XXI Cosmic Ray Conference, Adelaide, Australia, 7, p. 155Abazov, (1991) Phys.

Upper-face expression features extraction system for video sequences
No full textNowadays there are not any reliable systems able to codify a video streaming according to the FACS. The few system that are able to do it works on frontal, or however not natural postures. The system we propose, takes advantage from a robust 3D tracking based on a 3D template, in order to
extract some features correlated to the facial expressions.
Moreover, this system provides for each feature a reliability level according to the presence of some occlusions, or due to some errors in tracking that could hide or make the reconstruction on the template, become critical
Fuzzy weighted approach to improve visual quality of edge-based filtering
No full textA new algorithm for the deinterlacing of interlaced scanned video sequences is presented in this paper. The ultimate goal of the proposed algorithm is to exactly determine the unknown pixel value while preserving the edges and details of the image. Traditional edge direction-based interpolation algorithms usually introduce artifacts in the case of non-clear edges. In order to solve the above issues, we adopted fuzzy concepts to design a weight-evaluating technique. The weights were considered to be multiplied by the candidate deinterlaced pixels. Experimental results demonstrated that the resulting frames contained less errors and sharper edges than frames generated using common approaches such as median filtering and edge direction-based linear interpolation
Rough sets-assisted subfield optimization for alternating current plasma display panel
No full textPlasma display panel technology employs a pulse-number modulation method to generate the gradation of the display. However, this method can create a false contour distortion when moving pictures are reproduced. In this paper, we propose an effective subfield optimization technique which is based on measuring motion picture distortion. To this end, we propose two applications of the measurements. One is optimum selection of the codewords to improve performance, and the other is the application of rough sets theory to subfield optimization, which reduces computational CPU time. Simulation results show that dynamic false contouring can be effectively reduced by this optimization technique, and the complexity can be minimized, using rough sets theory
