Territories, observation and governance. Tools, methods and realities
2011
The thesis is presented in three parts which include the three key words of the title and put intoperspective the function of territorial observation, with an approach to complexity mostly empiricaland constantly referring to systemics.The first part focuses on the polysemic notion of territory. Modeling the process of territorializationallows us to bypass the semantic difficulty that arises from multiple uses of the term in the literatureand in interviews conducted with experts. The territory is then revealed in different forms ofcombinations of tangible and intangible dimensions, and individual or collective representations.The second part is based on concrete achievements of observatorie…
L'arte mantica alla prova dello scetticismo nell'Edipo re
2022
Since the beginning of the Sophoclean drama OT, King Oedipus, in his attempt to contrast the plague that afflicts Thebes, has to confront the traditional influence of the Delphic oracles and the opinion of the local seer, Tiresias, who is demanding to interpret the words of the God Apollo. In this sense, the Sophoclean drama seems to set into the Attic scene the main traits of its contemporary public debate (second half of the 5th Century BC) about power and fallibility of both oracles and their human interpreters, the so-called manteis. This paper aims by means of a detailed analysis of the dramatic discourse to investigate the positions expressed by the different characters involved in th…
An Improved Approach to the Simulation of Single-Line-to-Ground Faults in Transmission Networks
2009
These paper presents a mathematical model for studying the Single-Line-to-Ground fault in transmission networks, giving a personal contribution for a methodical and accurate analysis of complex systems, by providing an evolution of the “circuital method” able to solve the case of a system in which more than one line supply the fault.
Zur Beeinflussung der Mucopolysaccharide in Serum und Urin von Sklerodermiekranken durch Gestagen-Behandlung
1968
Die Hohe des Mucoprotein-Gehaltes im Serum und der Mucopolysaccharid-Ausscheidung im Urin bei Kranken mit progressiver Sklerodermie vor und nach Behandlung mit Gestagenen wurde bestimmt. Bei 6 von 8 Kranken war eine gesteigerte Mucopolysaccharid-Ausscheidung im Urin bei normalem Mucoprotein-Spiegel im Serum festzustellen. Diese erhohte Mucopolysaccharid-Ausscheidung im Urin kehrte bei den 3 hierauf untersuchten Kranken nach der Gestagen-Behandlung zum Normbereich zuruck. Gestagene regulieren demnach den gestorten Mucopolysaccharidstoffwechsel bei der Sklerodermie, wie dies von anderen Parametern des Bindegewebes bereits bekannt ist.
Manometrische untersuchungen zur oesophagusbeteiligung bei progressiver sklerodermie
1975
Bei 15 Patienten mit progressiver Sklerodermie wurde die Oesophagus funktion manometrisch und radiologisch untersucht. Nur ein Drittel der Patienten gab Schluckbeschwerden an. Dagegen liesen sich radiologisch bei 8 Patienten (55%) deutliche Motilitatsstorungen nachweisen, mit der Oesophagusmanometrie sogar bei 11 Patienten (73%). Fehlende subjektive Symptome schliesen demnach einen ausgedehnten Befall der Speiserohre nicht aus. Die manometrischen Messungen zeigen, das mit einer Beteiligung der Speiserohre im odematos-indurativen Stadium der Sklerodermie in einem wesentlichen hoheren Prozentsatz gerechnet werden mus, als ublicherweise aufgrund von Rontgenuntersuchungen allein angenommen wurd…
Chemical, Antioxidant and Biological Studies of Brassica incana subsp. raimondoi (Brassicaceae) Leaf Extract
2023
Brassica incana subsp. raimondoi is an endemic taxon present in a restricted area located on steep limestone cliffs at an altitude of about 500 m a.s.l. in eastern Sicily. In this research, for the first time, studies on the phytochemical profile, the antioxidant properties in cell-free and cell-based systems, the cytotoxicity on normal and cancer cells by 3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide (MTT) assay, and on Artemia salina Leach, were performed. The total phenolic, flavonoid, and condensed tannin contents of the leaf hydroalcoholic extract were spectrophotometrically determined. Ultra-performance liquid chromatography—tandem mass spectrometer (UPLC-MS/MS) analysi…

A Specialized Architecture for Color Image Edge Detection Based on Clifford Algebra
2013
Edge detection of color images is usually performed by applying the traditional techniques for gray-scale images to the three color channels separately. However, human visual perception does not differentiate colors and processes the image as a whole. Recently, new methods have been proposed that treat RGB color triples as vectors and color images as vector fields. In these approaches, edge detection is obtained extending the classical pattern matching and convolution techniques to vector fields. This paper proposes a hardware implementation of an edge detection method for color images that exploits the definition of geometric product of vectors given in the Clifford algebra framework to ex…
Fast, Reliable Head Tracking Under Varying Illumination
2003
An improved technique for 3D head tracking under varying illumination conditions is proposed. The head is modeled as a texture mapped cylinder. Tracking is formulated as an image registration problem in the cylinder's texture map image. To solve the registration problem in the presence of lighting variation and head motion, the residual error of registration is modeled as a linear combination of texture warping templates and orthogonal illumination templates. Fast and stable on-line tracking is then achieved via regularized weighted least squares minimization of the registration error. The regularization term tends to limit potential ambiguities that arise in the warping and illumination te…
Head Tracking via Robust Registration in Texture Map Images.
1998
A novel method for 3D head tracking in the presence of large head rotations and facial expression changes is described. Tracking is formulated in terms of color image registration in the texture map of a 3D surface model. Model appearance is recursively updated via image mosaicking in the texture map as the head orientation varies. The resulting dynamic texture map provides a stabilized view of the face that can be used as input to many existing 2D techniques for face recognition, facial expressions analysis, lip reading, and eye tracking. Parameters are estimated via a robust minimization procedure; this provides robustness to occlusions, wrinkles, shadows and specular highlights. The syst…
