Symmetric Galerkin BEM for Non Linear Analysis of Historical Masonries
2015
The preservation of the historical and monumental buildings, but also of the considerable heritage of old constructions made by traditional techniques, is one of the actual problems of the structural mechanics. The level of knowledge of their structural behavior in presence of external actions is made through calculus methods and simple procedures in order to allow a reading of the material suffering degree and as a consequence of the related safety. Unfortunately, often the masonry panels show openings located in an irregular way and cracks having small or big dimensions. In these cases the employment of strategies, as for example the identifying of the masonry piers and the transformation…
Methodological reflections: supervisory discourses and practice-based learning
2009
The concept of dialogue is often examined apart from the social and historical context in which it is embedded. This paper identifies how dialogue between a superior and a subordinate generates a reorganisation of situated knowledge in the education and training of nurse teachers. We created an analytic method of supervisory discourse founded on differences between discourse-based and practice-based theories. The findings elicit two forms of dialogues: transformative and exploratory. Through the former, supervisors try to make their students reformulate their understanding by facilitating learning through questions and hints or to support their self-reflections in local contexts. Conversely…
A Simple Monte Carlo Model of a Hot Carrier Cell
2017
In the present work, a simplified model of a hot carrier cell is examined at different energy levels of carrier collection. Incident photons, Monte Carlo generated by employing the ASTM G173–03 data set, are accounted for individually as they interact with the cell. The hot carrier cells are examined in a transient state caused by a flash of photons with AM1.5 spectrum. Excess photon energy is recycled giving a form of thermalization of hot carriers. The sensitivity of contact variables and the device band gap on cell efficiency, has been studied.
Diffusion of oxygen in cork.
2012
International audience; This work reports measurements of effective oxygen diffusion coefficient in raw cork. Kinetics of oxygen transfer through cork is studied at 298 K thanks to a homemade manometric device composed of two gas compartments separated by a cork wafer sample. The first compartment contains oxygen, whereas the second one is kept under dynamic vacuum. The pressure decrease in the first compartment is recorded as a function of time. The effective diffusion coefficient D-eff is obtained by applying Fick's law to transient state using a numerical method based on finite differences. An analytical model derived from Fick's law applied to steady state is also proposed. Results give…
Humour as a symptom of research trends in translation studies
2017
This article is an overview of translation studies applied to the case of humour, divided into four parts, plus an extensive bibliography. The first part goes over humour translation as a relevant object of research and why it is worthy of more academic attention. Humour translation should not be dealt with or looked upon as a strange body within translation studies. Part two is an overview of key contributions to the field, from Spain and elsewhere, covering a considerable number of authors and theories. Part three focuses on promising areas of interest for researchers and illustrates how audiovisual translation is a good instance of dynamism within the field, connecting all this to the ri…
Air Traffic, Boarding and Scaling Exponents
2014
The air traffic is a very important part of the global transportation network. In distinction from vehicular traffic, the boarding of an airplane is a significant part of the whole transportation process. Here we study an airplane boarding model, introduced in 2012 by Frette and Hemmer, with the aim to determine precisely the asymptotic power–law scaling behavior of the mean boarding time 〈t b 〉 and other related quantities for large number of passengers N. Our analysis is based on an exact enumeration for small system sizes N ≤ 14 and Monte Carlo simulation data for very large system sizes up to \(N = 2^{16} = 65,536\). It shows that the asymptotic power–law scaling 〈t b 〉 ∝ N α holds with…
New Coronavirus (SARS-CoV-2) Crossing Borders Beyond Cities, Nations, and Continents: Impact of International Travel
2021
The third outbreak of coronavirus in the form of the COVID-19 infection started in Wuhan, China, in December 2019. The early and rapid spread of this infection across borders can be largely attributed to international air travel that has become a part of modern globalization. In this article, we analyze the spread of the novel coronavirus (SARS-CoV-2) along the routes of international travel, both by air and by sea. Pitfalls of various screening methods used at the airports and the importance of optimal aircraft ventilation are discussed. Also, we suggest measures that can be taken to reduce the risk of transmission associated with air travel.
La intervenció de la/treballador/a social sanitari a la Comunitat Valenciana
2012
The purpose of this document is to provide both, professionals and citizens, with information about the procedures and processes of intervention developed by social workers within the different health institutions of the Community of Valencia. It is important to identify the specificity of Social Work in the Health Care System in order to consolidate Professional Identity from the homogeneity in the processes and procedures of intervention and the identification of the duties carried out by these professionals in the different health institutions/services of the Community of Valencia.
On solving separable block tridiagonal linear systems using a GPU implementation of radix-4 PSCR method
2018
Partial solution variant of the cyclic reduction (PSCR) method is a direct solver that can be applied to certain types of separable block tridiagonal linear systems. Such linear systems arise, e.g., from the Poisson and the Helmholtz equations discretized with bilinear finite-elements. Furthermore, the separability of the linear system entails that the discretization domain has to be rectangular and the discretization mesh orthogonal. A generalized graphics processing unit (GPU) implementation of the PSCR method is presented. The numerical results indicate up to 24-fold speedups when compared to an equivalent CPU implementation that utilizes a single CPU core. Attained floating point perfor…
Advanced Virgo Status
2015
Abstract The detection of a gravitational wave signal in September 2015 by LIGO interferometers, announced jointly by LIGO collaboration and Virgo collaboration in February 2016, opened a new era in Astrophysics and brought to the whole community a new way to look at - or “listen” to - the Universe. In this regard, the next big step was the joint observation with at least three detectors at the same time. This configuration provides a twofold benefit: it increases the signal-to-noise ratio of the events by means of triple coincidence and allows a narrower pinpointing of GW sources, and, in turn, the search for Electromagnetic counterparts to GW signals. Advanced Virgo (AdV) is the second ge…
