HISTORIC URBAN CENTERS. CONSTRUCTION CHARACTERS AND SEISMIC VULNERABILITY
2018
Parallelamente alla redazione di una micro-zonazione sismica che evidenzi le differenti risposte al sisma che i vari ambiti offrono in termini di amplificazione delle onde sismiche al suolo, in relazione alla stratigrafia e all’orografia del terreno, si rivela fondamentale conoscere e prevedere gli effetti di un sisma sul sistema urbano. È fondamentale quindi effettuare un’analisi del patrimonio costruito esistente al fine di conoscerne le caratteristiche, valutarne il livello di vulnerabilità ed individuare una scala di priorità di intervento, approfondendo in particolare l’indagine sui centri storici, contesti di particolare complessità, interesse storico e potenziale vulnerabilità. A par…
Augmented Mirror: Interactive Augmented Reality System Based on Kinect
2011
Part 1: Long and Short Papers; International audience; In this paper we present a virtual character controlled by an actor in real time, who talks with an audience through an augmented mirror. The application, which integrates video images, the avatar and other virtual objects within an Augmented Reality system, has been implemented using a mixture of technologies: two kinect systems for motion capture, depth map and real images, a gyroscope to detect head movements, and control algorithms to manage avatar emotions.
A Telegraph for China: The Attempted Application of Caselli’s Pantelegraph to Transmit Chinese Characters, 1856−87
2016
In 1872 the Shanghai-based newspaper Shenbao described an invention by Giovanni Caselli that allowed the production of telegraphic messages containing Chinese characters, the ‘pantelegraph’, an ancestor of the fax, reproducing manu- scripts, images and symbols, and, as such, totally suitable for Chinese telegraphy. In 1863, the Italian inventor had shown his invention to a legation of Chinese diplomats in France, producing some impressive Chinese transmissions, the caselligrammi. The envoys reported this information back home, but for some reasons a commercial contact was only set twenty years later. Although in many ways this seemed to be a perfectly suitable solution for the telegraphic c…
Iconicity in grammar chinese
2014
The notion of iconicity has become an interesting topic in the Western cognitive linguistics today. We chose to study the problem of iconicity in the context of Chinese grammar. Like any "ideographic" language, the Mandarin Chinese reveal a high degree of iconicity by his writing. In the history of Chinese linguistics, many studies have been done on the similarity between the form of the Chinese character and the sense which it represents. However, we only began to develop the notion of iconicity in the phonetic and syntactic domains with the introduction of cognitive linguistics in China thirty years ago. In this thesis, we will develop the notion of iconicity in the grammar of Chinese in …
Varieties of algebras with pseudoinvolution: Codimensions, cocharacters and colengths
2022
Abstract Let A be a finitely generated superalgebra with pseudoinvolution ⁎ over an algebraically closed field F of characteristic zero. In this paper we develop a theory of polynomial identities for this kind of algebras . In particular, we shall consider three sequences that can be attached to Id ⁎ ( A ) , the T 2 ⁎ -ideal of identities of A: the sequence of ⁎-codimensions c n ⁎ ( A ) , the sequence of ⁎-cocharacter χ 〈 n 〉 ⁎ ( A ) and the ⁎-colength sequence l n ⁎ ( A ) . Our purpose is threefold. First we shall prove that the ⁎-codimension sequence is eventually non-decreasing, i.e., c n ⁎ ( A ) ≤ c n + 1 ⁎ ( A ) , for n large enough. Secondly, we study superalgebras with pseudoinvoluti…
Correspondences Between 2-Brauer Characters of Solvable Groups
2010
Let G be a finite solvable group and let p be a prime. Let P ∈ Syl p (G) and N = N G (P). We prove that there exists a natural bijection between the 2-Brauer irreducible characters of p′-degree of G and those of N G (P).
A partition of characters associated to nilpotent subgroups
1999
IfG is a finite solvable group andH is a maximal nilpotent subgroup ofG containingF(G), we show that there is a canonical basisP(G|H) of the space of class functions onG vanishing off anyG-conjugate ofH which consists of characters. ViaP(G|H) it is possible to partition the irreducible characters ofG into “blocks”. These behave like Brauerp-blocks and a Fong theory for them can be developed.
The minimal number of characters over a normal p-subgroup
2007
Abstract If N is a normal p-subgroup of a finite group G and θ ∈ Irr ( N ) is a G-invariant irreducible character of N, then the number | Irr ( G | θ ) | of irreducible characters of G over θ is always greater than or equal to the number k p ′ ( G / N ) of conjugacy classes of G / N consisting of p ′ -elements. In this paper, we investigate when there is equality.
p-Parts of Brauer character degrees
2014
Abstract Let G be a finite group and let p be an odd prime. Under certain conditions on the p-parts of the degrees of its irreducible p-Brauer characters, we prove the solvability of G. As a consequence, we answer a question proposed by B. Huppert in 1991: If G has exactly two distinct irreducible p-Brauer character degrees, then is G solvable? We also determine the structure of non-solvable groups with exactly two irreducible 2-Brauer character degrees.
p-Brauer characters ofq-defect 0
1994
For ap-solvable groupG the number of irreducible Brauer characters ofG with a given vertexP is equal to the number of irreducible Brauer characters of the normalizer ofP with vertexP. In this paper we prove in addition that for solvable groups one can control the number of those characters whose degrees are divisible by the largest possibleq-power dividing the order of |G|.
