New Invariant Domain Preserving Finite Volume Schemes for Compressible Flows
2021
We present new invariant domain preserving finite volume schemes for the compressible Euler and Navier–Stokes–Fourier systems. The schemes are entropy stable and preserve positivity of density and internal energy. More importantly, their convergence towards a strong solution of the limit system has been proved rigorously in [9, 11]. We will demonstrate their accuracy and robustness on a series of numerical experiments.
Excitation energies and photoabsorption oscillator strengths of the Rydberg series in CF3Cl. A linear response and quantum defect study.
2007
Vertical excitation energies of the CF(3)Cl molecule have been obtained from a response function approach with a CC reference function to determine absolute photoabsorption oscillator strengths in the molecular-adapted quantum defect orbital formalism (MQDO). The present work covers more highly excited Rydberg states than have been experimentally reported. Assessing of the reliability of the present calculations is provided through a comparative analysis between the results of the molecule and the Cl atom. This can be used to allow for predictions of the same type of properties in other analogous systems.
Itô-Stratonovitch Formula for the Wave Equation on a Torus
2010
We give an Ito-Stratonovitch formula for the wave equation on a torus, where we have no stochastic process associated to this partial differential equation. This gives a generalization of the classical Ito-Stratonovitch equation for diffusion in semi-group theory established by ourself in [18], [20].
A Leibniz variety with almost polynomial growth
2005
Abstract Let F be a field of characteristic zero. In this paper we study the variety of Leibniz algebras V ˜ 1 defined by the identity y 1 ( y 2 y 3 ) ( y 4 y 5 ) ≡ 0 . We give a complete description of the space of multilinear identities in the language of Young diagrams through the representation theory of the symmetric group. As an outcome we show that the variety V ˜ 1 has almost polynomial growth, i.e., the sequence of codimensions of V ˜ 1 cannot be bounded by any polynomial function but any proper subvariety of V ˜ 1 as polynomial growth.
MQDO theoretical study of the C1Π–X1Σ+ band system of HCl
2008
Abstract Oscillator strengths for P, Q and R rotational lines belonging to the (0, v ″ = 0, 1) and (1, v ″ = 0, 1) bands for the C 1 Π–X 1 Σ + system of HCl have been theoretically studied. The calculations have been performed by following the molecular quantum defect orbital methodology, which has earlier proved to yield accurate intensities for transitions involving Rydberg states in a variety of molecular species. The results appear to be in good accord with the available experimental values. Predictions of a number of unknown intensities have also been made. We expect that the present data might be of help in the interpretation of future experimental measurements.
Theoretical Study of the Electronic Spectrum of trans-Stilbene
1997
The electronic spectrum of trans-stilbene in the energy range up to 6 eV has been studied using multiconfigurational second-order perturbation theory (CASPT2). The study includes a geometry determination of the ground state. In all, 12 singlet and one triplet excited states were studied. The calculated spectrum makes it possible to assign the valence excited singlet states corresponding to the three bands observed in the low-energy region of the one-photon absorption spectrum. The most intense feature of the calculated spectrum corresponds to the 11Ag → 21Bu transition at 4.07 eV. The weakly allowed 11Bu state was found 0.3 eV below 21Bu. Transition to the 31Ag state, computed at 4.95 eV, i…
Estimating Regional Input Coefficients and Multipliers: The Use of FLQ is Not a Gamble
2014
Flegg A. T. and Tohmo T. Estimating regional input coefficients and multipliers: the use of FLQ is not a gamble, Regional Studies. This paper re-examines the Finnish evidence presented by Lehtonen and Tykkylainen on the use of location quotients (LQs) in estimating regional input coefficients and multipliers. They argue that the choice of an LQ-based method is a gamble and that there is no single method that can be recommended for general use. It is contended here that this evidence is erroneous and that the FLQ (Flegg's location quotient) yields results far superior to those from competing formulae, so it should provide a satisfactory way of generating an initial set of input coefficients.…
Pepe-sammakko Kiasmassa : leikki, trollaaminen ja #ALONETOGETHER-taideteoksen affektiivisuus
2018
#ALONETOGETHER oli yleisön osallistumiseen perustuva taideteos Kiasmassa keväällä 2017. Siihen kohdistui toistuvaa trollausta, joka kumpusi taiteilijoiden aiemmasta poliittisesta toiminnasta ja siitä virinneistä keskusteluista internetin kuvalaudoilla. Analysoimme teoksen ympärillä tapahtunutta trollausta ja osoitamme, miten se on yhdistelmä affekteja, leikkiä ja poliittista toimintaa. peerReviewed
Riconfigurare i territori metroplitani. Forme di urbanizzazione e fenomeni di pressione insediativa sui sistemi di interesse naturale in Sicilia
2018
The consumption of the soil due to urbanization it is a phenomena already for many years under observations, but of which only the scientific environment has noticed the elevated environmental impact progress. From a disciplinary point of view, is possible to identify a line of research focusing on the analysis and identification of new morphologies of urbanization and on the interaction among different settlement patterns coexisting in a specific context. This reading complements with the scientific production about the forms of settlement pressure on environmental systems, producing change and deterioration on natural ecosystems and loss of biodiversity. A necessary reference for this lin…
An Edutainment Implementation in an English Vocational Training Class
2021
Edutainment ha sido definido como la unión entre la educación y el entretenimiento, aspectos que todo profesor querría tener en sus clases. Sin embargo, todavía no hay una implementación suficiente del enfoque para afirmar de una forma clara si es útil utilizarlo en las clases de aprendizaje de segundas lenguas o lenguas extranjeras. Este estudio tiene la ambición de contribuir a la comunidad educativa con un caso que podría ser un punto de partida para futuras investigaciones. En este trabajo se describe una investigación que duró 2 semanas en dos grupos de alumnos de 1º de un curso superior de formación profesional, donde se implementó el Edutainment en el grupo experimental y se implemen…
