A Low Mach Number IMEX Flux Splitting for the Level Set Ghost Fluid Method
No full textConsidering droplet phenomena at low Mach numbers, large differences in the magnitude of the occurring characteristic waves are presented. As acoustic phenomena often play a minor role in such applications, classical explicit schemes which resolve these waves suffer from a very restrictive timestep restriction. In this work, a novel scheme based on a specific level set ghost fluid method and an implicit-explicit (IMEX) flux splitting is proposed to overcome this timestep restriction. A fully implicit narrow band around the sharp phase interface is combined with a splitting of the convective and acoustic phenomena away from the interface. In this part of the domain, the IMEX Runge-Kutta time discretization and the high order discontinuous Galerkin spectral element method are applied to achieve high accuracies in the bulk phases. It is shown that for low Mach numbers a significant gain in computational time can be achieved compared to a fully explicit method. Applications to typical droplet dynamic phenomena validate the proposed method and illustrate its capabilities.Deutsche Forschungsgemeinschaft (DFG, German Research Foundation)Germa
A data-driven high order sub-cell artificial viscosity for the discontinuous Galerkin spectral element method
No full textIn this work, we present a novel higher-order smooth artificial viscosity method for the discontinuous Galerkin spectral element method and related high order methods. A neural network is used to detect the need for stabilization. Inspired by techniques from image edge detection, the neural network locates discontinuities inside mesh elements on a sub-cell level. Once the sub-cell positions of the shock fronts have been identified, the use of radial basis functions enables the construction of a high order smooth artificial viscosity field on quadrilateral meshes. We show the superiority of using higher order smooth artificial viscosity over piecewise linear approaches in particular on coarse meshes. The capabilities of the novel method are illustrated with typical applications. (c) 2021 Elsevier Inc. All rights reserved

Accentuation of Jonas Rėza's Psalter of 1625
No full textStraipsnyje trumpai apžvelgiama dabartinių kalbų kirčio ženklų istorija – nuo Antikos kalbininko Aristofano Bizantiečio žymėtų akūto, gravio ir cirkumflekso iki Mažvydo Katekizme pažymėto į riestinį cirkumfleksą panašaus ženklo, Baltramiejaus Vilento raštų, D. Kleino gramatikos, J. Rėzos psalmyno ,,Psalteras Dowido“ kirčio ženklų. Išsamiau straipsnyje analizuojamas 1625 m. J. Rėzos psalmyno kirčiavimas, iš graikų perimti kirčio ženklai, paties autoriaus įsivestas kirčio ženklas. Straipsnyje taip pat aptariama Rėzos psalmyne vartotų kirčio ženklų funkcijos, kirčio ženklų vartojimo įvairavimas, sąsajos tarp psalmyno kirčiavimo ir D. Kleino gramatikos Reikšminiai žodžiai: Akūtas; Gravis; Cirkumfleksas; Psalmynas; Lietuvių kalbos istorija; KirčiavimasThis article gives a brief overview of the history of the accent marks of languages from Antiquity linguist Aristophanes of Byzantium marked the acute accent, grave accent and circumflex accent until the sign similar to a tilde-shaped circumflex marked in Mažvydas’ Catechism, and accent signs of Baltramiejus Vilentas’ writings, Daniel Klein‘s grammer, and Jonas Rhesa’s Psalter of David. The article gives a comprehensive analysis of the accentuation made by Jonas Rhesa in the psalter, accent marks taken from Greek, and an accent mark developed by the author himself. The article also discusses the functions of the accent marks used in Rhesa’s psalter, the variation of the usage of accent marks and the interaction between the accentuation of the psalter and D. Klein’s grammer
Epistemología del riesgo y trama de la vida en tres autores de la modernidad crítica: Jonas, Beck y Giddens / Epistemology of risk and the weave of life in three authors from the critical modernity: Jonas, Beck and Giddens
No full textEste artículo explora la dimensión epistemológica del riesgo y sus implicaciones en la trama de la vida y
el futuro de lo viviente, según tres autores de la modernidad crítica: Hans Jonas, Ulrich Beck y Anthony
Giddens. Uno de los elementos que ellos denuncian es la negación del “no-saber” que priva a la sociedad
de su capacidad restrictiva frente a las decisiones de riesgo e impide el control social del conocimiento, la
ciencia y la técnica. Esta impronta se propone como uno de los rasgos de la colonialidad del saber y de la
naturaleza junto a otros como el antropocentrismo, los dualismos enajenantes y el carácter indetenible del
desarrollo y el progreso debido a la linealidad temporal que los anima. Finalmente, se sugieren alcances de
estos aportes, así como límites y enlaces con el pensamiento decolonial.The article explores the epistemological dimension of risk and its implications in the weave of life and the
