The Cauchy problem for linear growth functionals

2003

In this paper we are interested in the Cauchy problem $$ \left\{ \begin{gathered} \frac{{\partial u}}{{\partial t}} = div a (x, Du) in Q = (0,\infty ) x {\mathbb{R}^{{N }}} \hfill \\ u (0,x) = {u_{0}}(x) in x \in {\mathbb{R}^{N}}, \hfill \\ \end{gathered} \right. $$ (1.1) where \( {u_{0}} \in L_{{loc}}^{1}({\mathbb{R}^{N}}) \) and \( a(x,\xi ) = {\nabla _{\xi }}f(x,\xi ),f:{\mathbb{R}^{N}}x {\mathbb{R}^{N}} \to \mathbb{R} \)being a function with linear growth as ‖ξ‖ satisfying some additional assumptions we shall precise below. An example of function f(x, ξ) covered by our results is the nonparametric area integrand \( f(x,\xi ) = \sqrt {{1 + {{\left\| \xi \right\|}^{2}}}} \); in this case …

IA neuro-symbolique pour l'interprétation granulaire des données des bases STUPS© et OTARIES© : défis applicatifs et perspectives

2023

Historiquement, l'intelligence artificielle (IA) s'est divisée en 2 courants selon les hypothèses faites pour modéliser l'intelligence humaine : l'IA symbolique, supposant que des symboles sont nécessaires, et l'IA statistique (plus particulièrement l'IA connexionniste) affirmant le contraire. Dernièrement, l'IA neuro-symbolique tente de réconcilier les 2. Les travaux présentés dans cet article sont en en collaboration avec la Police Scientifique française, dans le contexte du Plan National Stup. Nous présentons les problématiques métiers en lien avec le projet, puis en déduisons les problématiques scientifiques. Après un rappel des domaines de l'IA et leurs limites, nous présentons un état…

Historischer Überblick zur mathematischen Theorie von Unstetigkeitswellen seit Riemann und Christoffel

1981

We give a brief historical account of the development of the mathematical theory of propagation of discontinuities in gases, fluids or elastic materials. The theory was initiated by Riemann who investigated the propagation of shocks in one-dimensional isentropic gas flow. Riemann’s results were used by Christoffel to treat, more generally, the propagation of (first order) discontinuity surfaces in three-dimensional flows of perfect fluids. Subsequently Christoffel applied his general theory to first order waves in certain elastic materials. Independently of Riemann and Christoffel significant contributions were made by Hugoniot. The theory was completed in Hadamard’s celebrated monograph [3…

The taboo against group contact: Hypothesis of Gypsy ontologization

2007

The concept of this article is that the symbolic relationships between human beings and animals serve as a model for the relationships between the majority and the ethnic minority. We postulate that there are two representations that serve to organize these relationships between human beings and animals: a domestic and a wild one. If the domestic animal is an index of human culture, the wild animal is an index of nature which man considers himself to share with the animal. With the wild representation, contact with the animal will be taboo, as it constitutes a threat to the anthropological difference. We offer the hypothesis that ontologization of the minority, that is, the substitution of …

Una è la forma, molti sono i nomi : scenari del sacro femminile tra la Sicilia e Creta

2022

Nei culti rivolti alle Madonne e alle Sante in Sicilia e a Creta, in particolare in quelli caratterizzati dall’ostensione e dalla manipolazione di fronde vegetali, dall’uso di acque salutifere, dal riutilizzo di antichi spazi cultuali (grotte, cime montuose, boschi), sembra continuino a reiterarsi modelli mitici e simboli rituali propri di un antico pattern del sacro femminile che, di volta in volta, disarticolato e rimodulato, si rivela tutt’altro che inattuale e che anzi continua a conferire senso alle molteplici e rinnovate istanze dell’esperienza religiosa contemporanea. Che si voglia ammettere ovvero respingere l’ipotesi di una relazione storica delle espressioni del sacro femminile e …

'Opera e declamazione teatrale in Italia nel Diciottesimo secolo. Convergenze e problemi'

2014

The fulfilment of the operatic reform, managed by Christoph Willibald Gluck and his librettist Ranieri Calzabigi in 1760s’ Vienna, is a well-known topic. This event, whose seeds date back to the 1740s, has been examined according to theatrical and literary experiences in France and Italy. However, the question of acting influence on opera can be reconsidered at the light of the latest discovery of symbols collected and labelled as drammatica – metodo italiano. Engraved in some writings, this set of signs is often connected to music and offers the matter for a new critical survey about the discourse on music declamation before and after Calzabigi. From the 1830s onwards the theory of acting …

Current caselaw discrepancies in the protection of national symbols and state representatives between the European Court of Human Rights and Spanish …

2021

Despite the general consensus about freedom of expression being a basic fundamental right on every democratic society, the debate about its boundaries has never found such a pacific agreement. Thus, the Spanish Penal Code has several articles that punish its abuse that are highly contested, like articles 490.3 and 543 that penalize the offenses directed towards national symbols or State representatives. This being so, this article examines the controversy generated by the application of this articles through the analysis of two judgements issued by the European Court of Human Rights against Spain, and a third one issued by the Spanish Constitutional Court that could follow the same path. Th…

Maturational effects on newborn ERPs measured in the mismatch negativity paradigm.

2003

Abstract The mismatch negativity (MMN) component of event-related potentials (ERPs), a measure of passive change detection, is suggested to develop early in comparison to other ERP components, and an MMN-like response has been measured even from preterm infants. The MMN response in adults is negative in polarity at about 150–200 ms. However, the response measured in a typical MMN paradigm can also be markedly different in newborns, even opposite in polarity. This has been suggested to be related to maturational factors. To verify that suggestion, we measured ERPs of 21 newborns during quiet sleep to rarely occurring deviant tones of 1100 Hz (probability 12%) embedded among repeated standard…
