Gray code for Cayley permutations

2003

A length-n Cayley permutation p of a total ordered set S is a length-n sequence of elements from S, subject to the condition that if an element x appears in p then all elements y < x also appear in p . In this paper, we give a Gray code list for the set of length-n Cayley permutations. Two successive permutations in this list differ at most in two positions.

Near-field observation of subwavelength confinement of photoluminescence by a photonic crystal microcavity

2006

We present a direct, room-temperature near-field optical study of light confinement by a subwavelength defect microcavity in a photonic crystal slab containing quantum-well sources. The observations are compared with three-dimensional finite-difference time-domain calculations, and excellent agreement is found. Moreover, we use a subwavelength cavity to study the influence of a near-field probe on the imaging of localized optical modes. © 2006 Optical Society of America.

Analysis of the Bloch mode spectra of surface polaritonic crystals in the weak and strong coupling regimes: grating-enhanced transmission at oblique …

2004

The Bloch mode spectrum of surface plasmon polaritons (SPPs) on a finite thickness metal film has been analyzed in the regimes of weak and strong coupling between SPP modes on the opposite film interfaces. The SPP mode dispersion and associated field distributions have been studied. The results have been applied to the description of the light transmission through thick and thin periodically structured metal films at oblique incidence. In contrast to normal incidence, all SPP Bloch modes on a grating structure participate in the resonant photon tunnelling leading to the transmission enhancement. However, at the angle of incidence corresponding to the crossing of different symmetry film SPP …

Optical properties of chlorine-and oxygen-related defects in SiO$_2$ glass and optical fibers

2018

International audience; Photoinduced processes involving chlorine molecules in synthetic silica were studied. Interstitial Cl$_2$ in SiO$_2$ are prevented from VIS/UV photolysis by cage effect. However, they react with oxygen interstitials yielding photosensitive ClClO molecules absorbing at 264nm.

Etudes d'objets combinatoires : applications à la bio-informatique

2011

This thesis considers classes of combinatorial objects that model data in bioinformatics. We have studied two methods of mutation of genes within the genome : duplication and inversion. At first,we study the problem of the whole mirror duplication-random lossmodel in terms of pattern avoiding permutations. We prove that the class of permutations obtained with this method after p duplications from the identity is the class of permutations avoiding alternating permutations of length 2p + 1.We also enumerate the number of duplications that are necessary and sufficient to obtain any permutation of length n from the identity. We also suggest two efficient algorithms to reconstruct two different …

Benefit of an animated simulation device for learning the highway code for deaf candidates : behavioural and physiological evaluation

2021

In France, the law called “loi handicap”, adopted on February 11th 2005, aims to ensure that people with disabilities benefit from the same conditions of access as all French citizens. The driving licence, because of its contribution to mobility, represents one of the major levers of an individual's general accessibility. Its successful completion improves social and professional integration. However, according to a parliamentary report of 2005, the success rate of deaf candidates in the theoretical exam of the highway code, allowing access to the practical exam of the driving license, was lower than that of hearing people.This thesis focuses on one of the possible causes of these differenc…

L’arbitrabilità delle azioni revocatorie e di inefficacia nella prospettiva del Codice della Crisi

2020

Tra i compiti del curatore vi è quello di ricostruire il patrimonio del debitore, al fine di garantire la par condicio creditorum. A questo scopo il curatore può proporre azioni dirette a far dichiarare la inefficacia degli atti compiuti dal debitore. Si tratta di azioni con presupposti ed effetti tra loro diversi; una azione è diretta a far dichiarare la inefficacia ex lege atti compiuti dal debitore; le altre sono lazione revocatoria ordinaria e l’azione revocatoria fallimentare. Per altro verso, il curatore potrebbe essere convenuto in azioni revocatorie dirette a fare dichiarare inefficaci atti di cui ha beneficiato il debitore prima del fallimento o la stessa curatela. In tutte queste …
