Equivalence between best responses and undominated
No full textFor games with expected utility maximizing players whose strategy sets are finite, Pearce (1984) shows that a strategy is strictly dominated by some mixed strategy, if and only if, this strategy is not a best response to some belief about opponents' strategy choice. This note generalizes Pearce's (1984) equivalence result to games with expected utility maximizing players whose strategy sets are arbitrary compact sets.
Odoardo Fialetti (1573-c.1638): the interrelation of Venetian art and anatomy, and his importance in England
No full textBolognese artist Odoardo Fialetti (1573 – c.1638) is a fascinating figure upon which curiously little work has been done. Though he is a rarely discussed pupil of Tintoretto, Fialetti’s oeuvre is vast (some 55 known paintings and approximately 450 prints) and incredibly diverse. His work encompasses religious subjects, portraits, books on drawing and sport, maps, and illustration for treatises on city defences, literary texts, and anatomy. His work was influential for several hundred years after his death, not only in Venice and northern Italy, but also in France where his designs were used as decoration on faïence produced at Nevers, and England, where his paintings were much admired at court. Fialetti’s close association with Sir Henry Wotton, and the careful copy of his drawing book made by Alexander Browne in the mid-seventeenth century, attest to his impact on the formation of an Italianate sensibility in the appreciation of the visual arts in Early Modern England. In the realm of science, Fialetti’s influence can be deduced from his drawings of curiously animated cadavers in detailed landscapes to those of future generations of anatomists and illustrators throughout Europe. Because of the diverse associations and projects throughout his career, the study of Fialetti is inherently interdisciplinary, encompassing the history of art, history of science and history of the Venetian book trade, as well as crossing geographical boundaries in linking Venetian art and English tastes of the late renaissance and early baroque. Through examination of his extant oeuvre, as well as discussion of lost work, I aim to recognise Fialetti’s status as an artist responding to contemporary artistic debates (disegno versus colorito), a changing cultural climate and the burgeoning importance of the printed medium
Alexandre Csoma de Körös, le bodhisattva hongrois
No full textAlexander Csoma de Kôrös, the Hungarian Bodhisattva
The Hungarian traveller Alexander Csoma de Kôrös (1784-1842) is the founder of tibetology. He is the author of the first dictionary and the first grammar of the classical Tibetan language, and of many other works on Tibetan culture. When he left his homeland for the East, his intention was to trace the mysterious origin of this people in high Asia, but he could not reach his initial aim, so that he remained in the Himalaya and became the first specialist of Tibetan buddhist civilisation. Man of high virtue and of exceptional determination, he has been proclaimed a bodhisattva on the 22nd of February 1933 at the Japanese university of Taishô, Tokyo, in recognition for the fundamental part he played in the discovery of Tibetan buddhism. He is the only European who may be regarded as a buddhist « saint ».Auteur du premier dictionnaire et de la première grammaire de la langue tibétaine classique, ainsi que de nombreux autres travaux sur le Tibet, le voyageur hongrois Alexandre Csoma de Körös (1784-1842) est le fondateur de la tibétologie. Parti en Asie avec l'intention d'y rechercher le berceau supposé de son peuple, il fut détourné par une série d'événements de son but initial et amené à s'intéresser longuement au monde himalayen, dont il fut le seul spécialiste jusqu'à sa mort. C'est en hommage au rôle pionnier qu'il joua dans la découverte de la civilisation bouddhique du Tibet, aux vertus dont il fit preuve toute sa vie, ainsi qu'à son indomptable courage, qu'il a été solennellement proclamé bodhisattva le 22 février 1933 à l'Université Taishô de Tokyo. Csoma de Körös se trouve ainsi le seul Blanc qui ait jamais été honoré d'un titre aussi prestigieux, comparable à ce que la sainteté est dans la tradition chrétienne.Le Calloc'h Bernard.

Inexpensive fusion methods for enhancing feature detection
No full textRecent successful approaches to high-level feature detection in image and video data have treated the problem as a pattern classification task. These typically leverage the techniques learned from statistical machine learning, coupled with ensemble architectures that create multiple feature detection models. Once created, co-occurrence between learned features can be captured to further boost performance. At multiple stages throughout these frameworks, various pieces of evidence can be fused together in order to boost performance. These approaches whilst very successful are computationally expensive, and depending on the task, require the use of significant computational resources. In this paper we propose two fusion methods that aim to combine the output of an initial basic statistical machine learning approach with a lower-quality information source, in order to gain diversity in the classified results whilst requiring only modest computing resources. Our approaches, validated experimentally on TRECVid data, are designed to be complementary to existing frameworks and can be regarded as possible replacements for the more computationally expensive combination strategies used elsewhere
Franz Liszt à Weimar d’après la correspondance inédite de Carl Alexander (1844-1861)
No full textInternational audienceThis articles is based on the unpublished diaries of grand-duke Carl Alexander of Sachsen-Weimar-Eisenach and his partly unpublished correspondence with Liszt (the edition is on preparation by the same author). It shows how close the two men were, and how Liszt advised the grand-duke for more than 40 years (1844-1886) on cultural and political issues. Liszt's role was non only to be a "Kapellmeister", but also a secrete and intimate minister to the grand-duke, as Goethe had been for Carl Alexander's grand-father, Carl August.Cet article, fondé sur les journaux intimes inédits du grand-duc de Saxe Carl Alexander et sur sa correspondance en partie inédite avec Franz Liszt (édition en cours par le présent auteur), démontre la proximité des deux hommes et la façon dont le compositeur a conseillé le grand-duc pendant plus de 40 ans sur les questions de culture et de politique culturelle. Le rôle de Liszt n'était pas celui d'un simple Maître de chapelle, mais il servait aussi de "ministre intime" pour le grand-duc, comme Goethe l'avait été pour le grand-père de Carl Alexander, Carl August

No full textZusammenfassung
Das von Alexander von Humboldt ab 1804 oder später verfasste Manuskript „Isle de Cube. Antilles en général“ wurde erst kürzlich zum ersten Mal veröffentlicht. Es stellt die Grundlage für den Essai politique sur l‘île de Cuba (1826) dar, der als das „wichtigste liberale Manifest des 19. Jahrhunderts gegen die Sklaverei“ gilt. Ziel der Untersuchung ist, die textgenetische inhaltliche und stilistische Entwicklung vom Manuskript zur Publikation ansatzweise nachverfolgen zu können, um Rückschlüsse auf Humboldts Arbeitsweise und Strategien als Autor mit einem politischen Anliegen zu ziehen.
Résumé
Le manuscrit «Isle de Cube. Antilles en général» – écrit par Alexander von Humboldt dès l’année 1804 ou plus tard, a été récemment publié pour la première fois. Il sert de fondation à l’Essai politique sur l’île de Cuba (1826), qui est considéré comme le «manifeste libéral le plus important du XIXe siècle contre l’esclavage». Cette étude propose une approche génétique concernant le contenu et le style du manuscrit jusqu’à la publication, pour en tirer des conclusions sur les méthodes et stratégies de travail de Humboldt comme auteur, notamment en lien avec des préoccupations politiques.
Summary
The manuscript “Isle de Cube. Antilles en général“, written by Alexander von Humboldt from 1804 onwards or later, has only recently been published. It is the groundwork for the Essai politique sur l’île de Cuba (1826), which is regarded as the “most important liberal manifesto against slavery of the 19th century“. The aim of this study is to trace the textual genesis of Humboldt’s work in regard to content and style from the manuscript to the publication in order to draw conclusions on Humboldt’s methods and strategies as an author with a political concern
Performance Prediction of Wideband Unambiguous Target Detection in Diffuse Ground Clutter
No full textIn this paper the influence of clutter power spectrum on unambiguous radar target detection with single low pulse repetition frequency wideband waveform is analyzed. Impact of both stationary and diffuse clutter components for different signal bandwidths and coherent processing intervals (CPI) is studied. Exponential model of the ground clutter power spectrum for the diffuse component is used. For the first time, radar detection performance for wideband signals at ambiguous to clutter velocities is predicted as function of bandwidth and CPI.Accepted author manuscriptMicrowave Sensing, Signals & System
Control Design for Linear Port-Hamiltonian Boundary Control Systems: An Overview
No full textn this paper, we provide an overview of some control synthesis methodologies for boundary control systems (BCS) in port-Hamiltonian form. At first, it is shown how to design a state-feedback control action able to shape the energy function to move its minimum at the desired equilibrium, and how to achieve asymptotic stability via damping injection. Secondly, general conditions that a linear regulator has to satisfy to have a well-posed and exponentially stable closed-loop system are presented. This second methodology is illustrated with reference to two specific stabilisation scenarios, namely when the plant is in impedance or in scattering form. It is also shown how these techniques can be employed in the analysis of more general systems described by coupled PDEs and ODEs. As an example, the repetitive control scheme is studied, and conditions to have asymptotic tracking of generic periodic reference signals are presented. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG
Le dialogue réglementaire Union européenne – États-Unis
No full textThe US-EU financial markets regulatory dialogue
The European financial integration comes within a worldwide and evolutional context where the financial sphere plays a particular role. So the transatlantic relation between the European Union and the United States takes a prominent position in the financial integration. Due to new rules imposed by the growing economical globalization, Europe and the United States implemented last years a regulatory dialogue intended to better analyse common stakes. First, the author reminds the context in which this regulatory dialogue and the reasons of its establishment are set up. This article tries to highlight the consequences of such collaboration and assesses the first results and some future perspectives.
JEL classification : F36, F42, G18, G28Le processus d’intégration financière européen doit s’inscrire dans un contexte mondial en évolution rapide, où la sphère financière joue un rôle particulier. Sous cet angle, la relation transatlantique entre l’Union européenne et les États-Unis occupe bien évidemment une place particulière. Du fait des nouvelles règles du jeu imposées par la mondialisation croissante de l’économie, l’Europe et les États-Unis ont mis en place, au cours de ces dernières années, un dialogue réglementaire destiné à mieux appréhender les enjeux communs. Après avoir rappelé le contexte dans lequel prennent place ce dialogue réglementaire et les raisons ayant mené à son établissement, cet article tente d’apporter un éclairage sur les apports d’un tel mécanisme de coopération, avant d’en faire un premier bilan et d’esquisser quelques perspectives pour l’avenir.
