This paper proposes a Schur complement-based Domain Decomposition Method to accelerate the time-domain simulation of large, non-linear and stiff Differential and Algebraic Equation systems stemming from power system dynamic studies. The proposed algorithm employs a star-shaped decomposition scheme and exploits the locality and sparsity of the system. The simulation is accelerated by the use of quasi-Newton schemes and parallel programming techniques. The proposed algorithm is implemented using the shared-memory parallel programming model and tested on a large-scale, realistic power system model showing significant speedup. [less ▲]

It is known that sum score-based methods for the identification of differential item functioning (DIF), such as the Mantel-Haenszel (MH) approach, can be affected by Type I error inflation in the absence of any DIF effect. This may happen when the items differ in discrimination and when there is item impact. On the other hand, outlier DIF methods have been developed that are robust against this Type I error inflation, while they are still based on the MH DIF statistic. The present paper gives an explanation for why the common MH method is indeed vulnerable to the inflation effect while the outlier DIF versions are not. In a simulation study we were able to produce the Type I error inflation by inducing item impact and item differences in discrimination. At the same time and in parallel with the Type I error inflation the dispersion of the DIF statistic across items was increased. As expected, the outlier DIF methods did not seem sensitive to impact and differences in item discrimination. [less ▲]

In this paper I discuss the dossier of cults for Arsinoe II Philadelphos to investigate how the worship of a sovereign could concretely become a constitutive part of the religious life of the communities composing a kingdom. I argue that in order to let the worship of a sovereign survive the political context in which it was first conceived, a certain degree of freedom and of individual initiative must have been encouraged among potential worshippers, so that the cults could become part of a durable shared religious and political identity connecting the individual with the collective sphere.

En 140/39 av. J.-C., une mission romaine composée, entre autres, de Scipion Emilien et du philosophe Panétios visita les alliés orientaux de Rome et se rendit notamment à Alexandrie. Le roi Ptolémée VIII y accueillit officiellement ces hôtes prestigieux, vêtu d’un habit étrange : un chiton long et subtil, dont les auteurs anciens réfèrent unanimement l’effet efféminé et caricatural, au point de susciter le rire des Romains et une condamnation du luxe effréné et décadent du royaume égyptien par comparaison avec la sobriété romaine. Il a fallu attendre une étude de H. Heinen en 1983 pour reconnaître, d’une part, l’envergure idéologique du lien entre la tenue de Ptolémée VIII – en fait empruntée à l’iconographie hellénistique de Dionysos – et la mise en scène officielle de la tryphè et du pouvoir royal et, de l’autre, le sens politique de la représentation caricaturale qu’en donna probablement déjà Panétios, représentation qui fut relayée et amplifiée par toute une tradition historiographique philo-romaine, qui se développa tout au long de la conquête romaine de la Méditerranée et ensuite à l’occasion du conflit entre Octavien et Antoine. Cette tradition nous a transmis, par le biais des auteurs de l’époque impériale, un discours fondé sur l’opposition entre Rome (et l’Italie), vertueuse source de citoyens et de soldats, et l’Orient dégénéré. Dans un tel cadre, Dionysos et le dionysisme sont sollicités pour servir à la construction d’un modèle accusatoire contre les ennemis de Rome, incarnant le désordre dans une dimension à la foi individuelle et institutionnelle. Mais est-ce que cette vision idéologique nous donne un portrait satisfaisant des rapports réels entre Rome et Dionysos / Bacchos / Liber Pater ? En partant de cette question, je propose dans ma contribution une approche visant à analyser, à l’aide de sources aussi littéraires que documentaires, les contextes de contact entre Rome et Dionysos de l’époque hellénistique au début du Principat, pour essayer de mettre en relief les relations entre, d’une part, la répulsion et le refus idéologiques du dionysisme, de l’autre les démarches d’appropriation et d’adaptation, à la culture romaine, de traits caractérisant les cultes hellénistiques de Dionysos et leurs utilisation dans la mise en forme des pratiques du pouvoir et de leurs représentations.

The material description is based on two constitutive elements, the grains (or bulk crystals) and the grainboundaries (GBs), both having their behavior determined atomistically using the quasicontinuum (QC) method by simulating the plastic deformation of [110] tilt crystalline interfaces undergoing simple shear, tension and nano-indentation. Unlike our previous work [V. Péron-Lührs et al., JMPS, 2013] however, the GB thickness is here calibrated in the model, providing more accurate insight into the GB widths according to the interface misorientation angle. In this contribution, the new two-scale model is also validated against fullyatomistic NC simulations tests for two low-angle and high-angle textures and two grain sizes. A simplified strategy aimed at predicting the mechanical behavior of more general textures without the need to run more QC simulations is also proposed, demonstrating significant reduction in computational cost compared to full atomistic simulations. Finally, by studying the response of dogbone samples made of NC copper, we show in this paper that such a two-scale model is able to quantitatively capture the differences in mechanical behavior of NC metals as a function of the texture and grain size, as well as to accurately predict the processes of inter-granular fracture for different GB character distributions. This two-scale method is found to be an effective alternative to other atomistic methods for the prediction of plasticity and fracture in NC materials with a substantial number of 2-D grains such as columnar-grained thin films for micro-scale electro-mechanical devices.

Dopo una introduzione storica e storiografica sul significato dei culti regali ellenistici, l’intervento esamina alcuni dei nomi divini attribuiti ad Arsinoe II nelle fonti letterarie e documentarie, con l’eccezione dell’epiclesi esclusiva Philadelphos. Scopo della ricerca è 1) una valutazione delle strategie di inserimento della nuova dea nel pantheon tradizionale; 2) una riflessione sull’autoconsapevolezza degli antichi in relazione alla propria tradizione religiosa, per come essa si manifesta attraverso l’oculata manipolazione di un elemento essenziale nella definizione della divinità, qual è il nome divino. Un’Appendice elenca, in tre tabelle, tutte le denominazioni greche di Arsinoe II (esclusa Philadelphos), fornendo indicazioni sulla fonte, la sua collocazione spaziale e temporale e sulla divinità tradizionale di riferimento.

I discuss the role of women and erōs in court poetry, by focusing on the ruling pair, i.e. the couple par excellence, and arguing that a gentle, reciprocal love within the bonds of marriage is presented as a crucial value, ensuring wealth and social order as well as the continuity of the dynasty itself. Because court life is a fashionable source of models for the elite, the poetic motif of requited love also influences the ideal depiction of love outside the ruling pair. After focusing on how internal patterns of relationship between characters shape the role of the queen in Alexandrian court poetry, I turn to non-literary, epigraphic evidence, in order to show how poetic representations of royal love integrate into a wider ideological program. Although my study mainly concerns Ptolemaic ruling pairs, I discuss some epigraphic parallels from the Seleucid dynasty as well, so that some general observations can be made on early Hellenistic queenship.
