OPTIMIZATIONS FOR TENSORIAL BERNSTEIN–BASED SOLVERS BY USING POLYHEDRAL BOUNDS
2010
The tensorial Bernstein basis for multivariate polynomials in n variables has a number 3n of functions for degree 2. Consequently, computing the representation of a multivariate polynomial in the tensorial Bernstein basis is an exponential time algorithm, which makes tensorial Bernstein-based solvers impractical for systems with more than n = 6 or 7 variables. This article describes a polytope (Bernstein polytope) with a number of faces, which allows to bound a sparse, multivariate polynomial expressed in the canonical basis by solving several linear programming problems. We compare the performance of a subdivision solver using domain reductions by linear programming with a solver using a c…
Dans le sillage de Hoffmann : naissance du fantastique en Russie
2014
International audience; Cet article se penche sur l’'héritage de Hoffmann dans l'édification russe du genre fantastique. La place dévolue au conteur allemand permet en effet de mettre en valeur de manière privilégiée les enjeux politiques et philosophiques du fantastique romantique russe, et ainsi de caractériser la dimension profondément spéculaire de ce fantastique, qui interroge le geste créateur.
Le discours du fou dans le récit romantique européen (Allemagne, France, Russie)
2012
The thesis studies the linguistics, philosophy and aesthetics of literary language of the madman in the Romantic era. It focuses on The Devil's Elixirs (Hoffmann, 1815),The Crumb Fairy (Nodier, 1832), The Diary of a Madman(Gogol, 1835), The Sylph(Odoevsky, 1837) and Aurelia(Nerval, 1855). Other narratives are more promptly summoned, as The Night Watches(Bonaventura, 1804) or Louis Lambert(Balzac, 1832).The madman is a problematic being: he is both unhealthy and inhabited by a divine inspiration. This paradox finds a new relevance in the first half of the nineteenth century. On the one hand, the development of Alienism tends to define mental pathologies from a medical point of view. On the o…

Narcisse et Pygmalion : le peintre fou dans la littérature fantastique romantique
2012
This article examines the relationship between creation and self-esteem, through the analysis of five nineteenth century narratives, The Jesuit Church in Glogau and The Devil's Elixirs by E. T. A. Hoffmann, The Oval Portrait by Edgar Poe, The Unknown Masterpiece by Honoré de Balzac and Walter Eisenberg by Konstantin Aksakov. According to Ovid, Pygmalion manages to create a fertile woman, contrary to Narcissus. However, from an Christian and moral point of view, self-esteem happens to be doubly condemned: it leads human beings away from God and other people. Therefore, the point is to determine if romantic narratives succeed in defying this pattern and create self-sufficient artists able to …
Folie et présence de l’origine dans la littérature romantique
2011
International audience; Emmanuel Kant, dans son « Esthétique transcendantale », affirme que le temps est à la fois subjectif et universel. Le temps n'est pas une donnée du monde objectif, mais il est néanmoins universellement nécessaire à la représentation humaine du monde. Les auteurs romantiques, en mettant en scène des fous, s'accordent sur le premier point, mais récusent le second. Les héros de Princesse Brambilla de E. T. A. Hoffmann, de La Félicité de la Folie de Nicolas Polévoï et d'Aurélia de Gérard de Nerval vivent dans un rapport au temps qui leur est propre. Cyclique et non linéaire, il conduit à superposer plusieurs temporalités, qui nient ainsi le principe de succession. Ce rap…
Analysis of economic activity and perspectives of development of SIA “Ernst & Young Baltic” during COVID-19
2022
Maģistra darba pētījuma aktualitāti pamato ar COVID-19 vīrusa ietekmi uz tautsaimniecību, tajā skaitā - grāmatvedības, revīzijas un dažādu biznesa konsultāciju pakalpojumiem, līdz ar to nepieciešamību novērtēt ietekmi uz SIA “Ernst & Young Baltic” saimnieciskās darbības rezultātiem. Pētījuma mērķis - pamatojoties uz teorētiskām atziņām un SIA “Ernst & Young Baltic” saimnieciskās darbības analīzi, novērtēt uzņēmuma attīstības perspektīvas COVID-19 krīzes apstākļos. Nozīmīgākie iegūtie rezultāti – pētītais uzņēmums ir starptautisks, COVID-19 ietekme nav būtiska, galvenais risks tiek saskatīts uzņēmuma klientu darbības pārtraukšanas vai ierobežošanas iespējamībā, konsultāciju sarežģītības pakā…
Fabrication of Single Cylindrical Au-Coated Nanopores with Non-Homogeneous Fixed Charge Distribution Exhibiting High Current Rectifications
2014
We have designed and characterized a cylindrical nanopore that exhibits high electrochemical current rectification ratios at low and intermediate electrolyte concentrations. For this purpose, the track-etched single cylindrical nanopore in polymer membrane is coated with a gold (Au) layer via electroless plating technique. Then, a non-homogeneous fixed charge distribution inside the Au-coated nanopore is obtained by incorporating thiol-terminated uncharged poly(N-isopropylacrylamide) (PNIPAM) chains in series to poly(4-vinyl pyridine) (PVP) chains, which are positively charged at acidic pH values. The functionalization reaction is checked by measuring the current–voltage (I–V) curves prior …
Quantifying the inverse spin-Hall effect in highly doped PEDOT:PSS
2020
The authors provide experimental results that show the onset of the Nernst effect, thermovoltages and an inverse spin-Hall effect in the polymer PEDOT:PSS. Specifically, the observed inverse spin-Hall effect appears to be smaller than other measurements, but in better agreement with theoretical calculations.
