Finite element approximation for a div-rot system with mixed boundary conditions in non-smooth plane domains
1984
The authors examine a finite element method for the numerical approximation of the solution to a div-rot system with mixed boundary conditions in bounded plane domains with piecewise smooth boundary. The solvability of the system both in an infinite and finite dimensional formulation is proved. Piecewise linear element fields with pointwise boundary conditions are used and their approximation properties are studied. Numerical examples indicating the accuracy of the method are given. peerReviewed
Inverse problems and invisibility cloaking for FEM models and resistor networks
2013
In this paper we consider inverse problems for resistor networks and for models obtained via the finite element method (FEM) for the conductivity equation. These correspond to discrete versions of the inverse conductivity problem of Calderón. We characterize FEM models corresponding to a given triangulation of the domain that are equivalent to certain resistor networks, and apply the results to study nonuniqueness of the discrete inverse problem. It turns out that the degree of nonuniqueness for the discrete problem is larger than the one for the partial differential equation. We also study invisibility cloaking for FEM models, and show how an arbitrary body can be surrounded with a layer …
On FE-grid relocation in solving unilateral boundary value problems by FEM
1992
We consider FE-grid optimization in elliptic unilateral boundary value problems. The criterion used in grid optimization is the total potential energy of the system. It is shown that minimization of this cost functional means a decrease of the discretization error or a better approximation of the unilateral boundary conditions, Design sensitivity analysis is given with respect to the movement of nodal points. Numerical results for the Dirichlet-Signorini problem for the Laplace equation and the plane elasticity problem with unilateral boundary conditions are given. In plane elasticity we consider problems with and without friction. peerReviewed
Influenze tra processo ed esiti: alleanza, coesione e cambiamento in un gruppo terapeutico a lungo termine
2012
Questo lavoro esplora, in un gruppo terapeutico con pazienti gravi, due tra le variabili di processo più indagate nelle terapie di gruppo, l’alleanza terapeutica e la coesione, analizzandone le associazioni con gli esiti del trattamento in termini di sintomi e difese. E’ stato esaminato un gruppo a lungo termine, semi-aperto, a cadenza settimanale. L’osservazione si è svolta per un periodo di 18 mesi, per un totale di 50 sedute. Sono stati monitorati 11 soggetti che riportavano diverse diagnosi nell’Asse I e II del DSM IV. TR Gli strumenti di esito usati sono stati l’SCL-90: Symptom Check List; l’ OQ-45: Outcome Question-naire 45.2; e il DSQ: Defense Style Questionnaire. Mentre per rilevare…
Dimensiunea Economică a Strategiei Europa 2020
2012
The aim of the paper is to present the economic dimension of the Europe 2020 strategy. The new strategy of European Union, was launched on 3 march 2010, as a response for economic crisis. Considerated as a new agenda for economic problem, continue, as Lisbon strategy did, to offer a new instrument to boost growth and jobs in all EU’s country. It contains 3 key priorities: smart growth, sustainable growth and inclusive growth. The economic dimension identify 3 headline targets that EU must achive them until 2020: 75 % of the population aged 20-64 should be employed; 3% of the EU's GDP should be invested in R&D and „20/20/20” climate/energy targets. The two primary research objective are: 1. …
ECONOMY OF SIBIU COUNTY. RESOURCES FOR A FUTURE DEVELOPMENT
2015
Economically, the County of Sibiu has been characterized, especially after 2007, by an accelerated speed of development, the recorded increase pushing our County among the most dynamic economies at regional and national level as well. The present paper aims at analyzing the specificity of the economic development of Sibiu County, namely to identify the resources of the obtained economic progress. The purpose of this study also consists in identifying new opportunities for the local economy, outlining new sources of development that are more important as competition, both at regional and national level, is tighter and tighter.
La Concepción de María en el tiempo. Recuperación de fórmulas tempranas de representación de la Inmaculada Concepción en la retórica visual del virre…
2014
This paper addresses a genuine aspect of conceptionist visual rhetoric during the Viceroyalty of New Spain: the recycling of Immaculate Conception earlier types of representation that, with the consolidation of the image of the Immaculate derived from the Tota Pulchra, had fallen deprecated in the peninsular art. The tendency of artists and patrons towards these typologies reveals a key aspect to understand the definition of Hispanic culture during the centuries of the Baroque. In the peripheral areas of the Empire, instead of continuous affirmation of the existence of a single Hispanic world, the springs of control over the religious image allowed variability in the implementation of the C…
Yoga en España. Proceso de regulación profesional
2015
New approaches to spirituality go hand in hand with emerging physical, psychological and spiritual movements that have had a clear impact on many areas, and in particular on health and well-being. It is increasingly common to find nurses teaching yoga or doctors prescribing mindfulness. Use of socalled Complementary and Alternative Medicine (CAM) is becoming mainstream. Health centres, medical practices and even schools are offering a growing number of alternative therapies, resulting in the need for effective legal regulation of these activities, both in terms of professional recognition and training. In Spain, recent legislation represents a significant breakthrough in the regulation of y…
La escritura sobre el pavimento callejero: Los mensajes de felicitación
2014
The aim of this paper is to study the sidewalk as a communications medium, especially in the urban environment. To do so, we collected a corpus of a thousand institutional, businessrelated or personal messages from the sidewalk. This corpus comprises slogans, advertisements, protests, affectionate statements, congratulations... From among all these sidewalk writings, first we collected and examined messages targeting citizens in general, and then focused on birthday greetings in particular because they were more numerous and also because they reflect social transformations.El objetivo de este trabajo es estudiar el suelo como soporte comunicativo, especialmente en las ciudades. Para ello, s…
Kolm tegelast poola naljades
2012
Teesid: Kaesoleva artikli eesmark on kirjeldada poola anekdoote kolmest tegelasest, ning anda ulevaade nende ajaloost ja muutumisest. Keskendutakse kolmese ulesehitusega naljadele, mille sisu on muutunud etnilisest ametitega seonduvaks. Artikkel puuab vastata kesksele kusimusele, kui universaalsed voi kultuurispetsiifilised on sellised naljad. Folkloorne ja globaalselt levinud ettekujutus numbri 3 tahendusest pakub samuti huvitavaid sissevaateid kolme tegelasega anekdootide olemusse. Kirjeldatakse stereotuupseid juhte, kus erinevate rahvuste esindajad kaituvad oodataval moel, ning analuusitakse konealuste anekdootide erinevate aspektide – etniliste, poliitiliste, seksuaalsete, loogiliste ja…
