A high-resolution layer-wise discontinuous Galerkin formulation for multilayered composite plates

2020

Abstract In this work, a novel high-resolution formulation for multilayered composite plates is presented. The formulations is referred to as high-resolution since it combines (i) Layer-Wise plate theories, which are based on a per-layer, high-order expansion of the primary variables throughout the plate’s thickness, providing a detailed layer-level description of the sought solution; (ii) The discontinuous Galerkin method, a numerical approach based on a discontinuous representation of the unknown fields over the mesh elements and on the introduction of boundary integral operators enforcing inter-element continuity, which allow the natural treatment of high-order mesh elements and provide …

Layer-Wise Discontinuous Galerkin Methods for Piezoelectric Laminates

2020

In this work, a novel high-order formulation for multilayered piezoelectric plates based on the combination of variable-order interior penalty discontinuous Galerkin methods and general layer-wise plate theories is presented, implemented and tested. The key feature of the formulation is the possibility to tune the order of the basis functions in both the in-plane approximation and the through-the-thickness expansion of the primary variables, namely displacements and electric potential. The results obtained from the application to the considered test cases show accuracy and robustness, thus confirming the developed technique as a supplementary computational tool for the analysis and design o…

Approaches to Film and Reception Theories

2012

Les différentes approches de la question des réactions du " public ", aussi difficile soit-il de définir ce terme, conçoivent celles-ci comme étant déterminées, soit par la structure de l'œuvre, par le contexte historique et culturel dans lequel cette réception se déroule, ou par les caractéristiques individuelles de ce public, lecteur ou spectateur. Ce recueil propose de faire le point sur l'état de la recherche actuelle, et d'offrir de nouvelles perspectives dans l'étude de la réception, et de la manière dont elle évolue et conditionne notre rapport à l'art. Les travaux présentés ici se concentrent sur la littérature et surtout le cinéma, et visent à croiser des perspectives que la critiq…

CONTEMPORARY THEORIES OF ADULT LEARNING

2015

<p>Due to the adult learning theory transition from cognitive to comprehensive aspects, this article analyses contemporary theoretical notions about adult’s learning. In order to characterise the modern view on adult, the most recent insights into the education of whole adult person (P. Jarvis), three dimensions of learning (K.Illeris) and the critical theory contribution (S.D. Brookfield) will be discussed. All of mentioned, globally-renowned theorists are of the same opinion and contribute to the general adult learning theory – P. Jarvis pictures the learning process from a viewpoint of a human as holistic organism, K.Illeris develops his theory in relation to the pedagogical condit…

Testing Three Theories of Cognitive Dysfunction in Problem Alcohol Use

2014

- Objectives : many hypotheses concerning the cognitive functions affected by chronic alcoholism have been advanced. The aim of this study was to test cognitive performance in a sample of alcoholics and to examine results comparing three different models: the frontal lobe hypothesis, the lateralization hypothesis and the diffuse brain hypothesis. - Methods : 51 patients who refer to alcoholism service have been included in this study. Cognitive functions were assessed by trained psychologist with a specific neuropsychological battery. -Results : our results show a ranking of impairment degrees in different cognitive functions and different influence of clinical features. In our sample the f…

Le rappresentazioni del corpo "anaisthētos" nel "Corpus Hippocraticum": una 'via negativa' verso la conoscenza

2010

This paper seeks to investigate the medical representations and descriptions of ἀναισθησία as we find them in the Hippocratic Corpus. It represents an attempt to analyze both the cognitive and the physiological aspects of perception and, above all, its distortion and/or absence in Hippocratic medicine. The medical phenomenology of ἀναισθησία will be considered in respect to both its outcomes (inability to perceive the outside world; inability to perceive one's internal states), but also in the light of, and in connection with, other phenomena like the absence/suspension of phonation, disturbances of breathing, alteration of the body's motor functions, and insensibility to pain.

Measuring something that cannot be grasped – Reflections about Methodology in Elicitation of Spoken Competence

2014

The focus of this article is on reflections about methodology and the methodical choices in empirical research into the role of consciousness in the acquisition of spoken competence in German as second or third foreign language. Seeing language as a complex, dynamic system, I want to show how learning fluctuates. I would like to demonstrate that there is a continuous fluctuation between nonlinearity and stability which depends on particular driving forces. These forces have to be captured by methods whose aim is to increase the certainty of data. These reflections were proved by a case that wants to demonstrate how a multi-methodical approach works in this direction.

Search for intermediate mass black hole binaries in the first and second observing runs of the Advanced LIGO and Virgo network

2019

Gravitational wave astronomy has been firmly established with the detection of gravitational waves from the merger of ten stellar mass binary black holes and a neutron star binary. This paper reports on the all-sky search for gravitational waves from intermediate mass black hole binaries in the first and second observing runs of the Advanced LIGO and Virgo network. The search uses three independent algorithms: two based on matched filtering of the data with waveform templates of gravitational wave signals from compact binaries, and a third, model-independent algorithm that employs no signal model for the incoming signal. No intermediate mass black hole binary event was detected in this sear…
