An Efficient Numerical Method for Time Domain Computational Electromagnetic Simulation
2018
In this paper an efficient numerical method in approximating the electric and magnetic fields is provided. The method is based on an implicit leapfrog arrangement in time and without mesh in space. Moreover, a projection scheme is introduced in order to improve the accuracy of the proposed approach and applied into the computational electromagnetic (CEM) framework. The PDEs governing the process are solved and some numerical results are reported to validate the numerical process.
Post-fatigue fracture resistance of metal core crowns: press-on metal ceramic versus a conventional veneering system
2014
Background The aim of this in vitro study was to compare the mechanical failure behavior and to analyze fracture characteristics of metal ceramic crowns with two veneering systems – press-on metal (PoM) ceramic versus a conventional veneering system – subjected to static compressive loading. Material and Methods Forty-six crowns were constructed and divided into two groups according to porcelain veneer manufacture. Group A: 23 metal copings with porcelain IPS-InLine veneering (conventional metal ceramic). Group B: 23 metal copings with IPS-InLine PoM veneering porcelain. After 120,000 fatigue cycles, the crowns were axially loaded to the moment of fracture with a universal testing machine. …
Treatment of flying phobia using virtual reality exposure with or without cognitive restructuring: Participant's preferences
2015
This study analyses participants’ preferences regarding two exposure treatment modali- ties for Fear of Flying (FF): virtual reality exposure treatment (VRET) by itself or VRET plus cognitive restructuring (VRET+CR). An alternating treatment conditions design was established and a non-concurrent multiple baseline design across individuals (four participants) was used. Both conditions were equally effective and after the treatment all the participants took a flight. At the end of each session the participants were asked for their opinion on the condition they received. High mean scores were obtained in both conditions; non-significant differences between the two condi- tions were found. When…
The Life, Death and Miracles of Alan Mathison Turing
2010
The life of Alan Turing is described in many biographies. The best and most encyclopaedic of these is that of Andrew Hodges; quite pleasant is the agile volume by Gianni Rigamonti, Turing, il genio e lo scandalo (Flaccovio editore, Palermo, 1991). Both of these also make mention of his tragic end, which certainly casts a shadow on the mores English society at the time; but of course, who knows how other societies might have behaved?
Acceptability of virtual reality interoceptive exposure for the treatment of panic disorder with agoraphobia
2013
Interoceptive exposure (IE) is a standard component of cognitive-behavioural therapy (CBT) for panic disorder and agoraphobia. The virtual reality (VR) program ‘Panic-Agoraphobia’ has several virtual scenarios designed for applying exposure to agoraphobic situations; it can also simulate physical sensations. This work examines patients' acceptability of the IE component as applied in two different ways: using VR versus traditional IE. Additionally, it explores the relationship between users' treatment expectations and satisfaction and clinically significant change. Results showed that VR and traditional IE were well accepted by all participants. Furthermore, treatment expectations predicted…
The cognitive therapy of evaluation: Therapeutic techniques-[2]
1991
Abstract The main aim of this paper is to introduce the techniques used in cognitive therapy of evaluation. The Cognitive therapy of evaluation is being developed from the theoretical background of general semantics theory and it is a therapy based on language as an instrument of cognitive processes, and on the role it plays, through word-facts identification, in the development and treatment of emotional problems. The main techniques developed (abstraction orders and the extensional devices) and other therapeutic issues are introduced and explained.
Supporting public decision process in buildings energy retrofitting operations: the application of a Multiple Criteria Decision Aiding model to a cas…
2020
Abstract The challenge of promoting sustainable cities and reaching the objectives developed by the European Green Deal includes the renovation of the building sector, as it is responsible for 40% of energy consumption in Europe. Regional or local public administrations have to allocate their financial resources for improving the energy performances of their building stock and to face a multidimensional problem, where different aspects – such as energy efficiency, financial-economic feasibility and environmental protection – have to be harmonized. The present study proposes a Multiple Criteria Decision Aiding model, which includes the ELECTRE TRI-nC method, for supporting the public decisio…
Estudio faunístico de los mosquitos (Díptera, Culicidae) de la comarca del Somontano de Barbastro y su posible relevancia en la difusión del paludismo
2013
Se han capturado 1.106 ejemplares larvarios de culícidos pertenecientes a 12 especies en la Comarca del Somontano de Barbastro, de las cuales dos (Culex impudicus y Cx. territans) se citan por primera en la provincia de Huesca. Pese a que la especie más abundante fue Cx. pipiens, desde un punto de vista epidemiológico señalar la elevada presencia de mosquitos del género Anopheles, potenciales vectores de la malaria, en diversas regiones de la comarca. Especialmente relevante es la destacada densidad que presenta An. atroparvus, importante vector palúdico, en biotopos concretos de la región más meridional del área de estudio. Adicionalmente, también se han detectado especies muy antropofílic…
Experimental and numerical assessment of subsurface plastic deformation induced by OFHC copper machining
2015
Strain distributions in the machined surface and subsurface of OFHC copper workpieces were determined experimentally and through numerical simulations. An experimental setup, comprising a double frame camera and a pulsed laser, was developed to measure the displacement fields using the digital image correlation (DIC) technique; strain distributions were then calculated. A numerical orthogonal cutting model was also developed and applied in order to predict such distributions. Comparison between simulated and measured results enabled an understanding of the fundamental mechanisms of plastic deformation of the machined surface of OFHC copper.; International audience; Strain distributions in t…
Iterative construction of Dupin cyclides characteristic circles using non-stationary Iterated Function Systems (IFS)
2012
International audience; A Dupin cyclide can be defined, in two different ways, as the envelope of an one-parameter family of oriented spheres. Each family of spheres can be seen as a conic in the space of spheres. In this paper, we propose an algorithm to compute a characteristic circle of a Dupin cyclide from a point and the tangent at this point in the space of spheres. Then, we propose iterative algorithms (in the space of spheres) to compute (in 3D space) some characteristic circles of a Dupin cyclide which blends two particular canal surfaces. As a singular point of a Dupin cyclide is a point at infinity in the space of spheres, we use the massic points defined by J.C. Fiorot. As we su…
