Modulational instability and domain wall solitons in optical fibers

2000

The first part of this thesis presents some theoretical and experimental results about modulational instability and domain wall solitons in bimodal fibers.In the second part is devoted to the interaction of counter-propagating waves in an isotropic optical fiber

Seismically induced, non-stationary hydrodynamic pressure in a dam-reservoir system

2003

Stochastic seismic analysis of hydrodynamic pressure in a dam-reservoir system is presented in this paper. The analysis is conducted assuming infinite reservoir compressible fluid and modeling seismic acceleration as a normal zero-mean stochastic process obtained by Penzien filter. The non-homogeneous boundary conditions associated to the problem have been incorporated into the equation of pressure wave scattering in the form of a forcing function turning the non-homogeneous boundary value problem into an homogeneous one. Solution obtained via modal analysis in time-domain is coupled with the use of classical Ito stochastic differential calculus to characterize the stochastic hydrodynamic p…

Modal and Structural FEM Analysis of a 50 ft Pleasure Yacht

2012

In this paper a structural Finite Element analysis of a 50 ft pleasure vessel is presented. The study is performed under different loads conditions: modal analyses have been done in order to find the natural frequencies of the vessel, structural analyses to verify the strength of the vessel to design loads. The design loads for the vessel considered are computed according to RINA rules for the construction and classification of pleasure vessels [1]. Two different composites are used for the lamination: one is a monolithic sequence of short fibre and balanced glass lamina, used for the bottom of the vessel and for structural reinforcements, the other is a sandwich made of glass fibre composi…

Rehabilitation with implant-supported overdentures in total edentulous patients: a review

2013

Objectives: The main aim of this review article is to discuss implant-supported overdentures (ISOs) as treatment in edentulous patients. Besides, we will try to discuss among the different treatment options in such patients and to analyze their validity when ISOs are compared with other clinical modalities. At the same time, we will try to suggest clinical guidelines supported by current clinical studies. Material and methods: We performed a Medline search and review of pertinent articles on the mentioned subject from 1986 to 2011. As a searching strategy, we used the following words: implant-supported overdentures, attachment systems, Locator attachment, cantilever, fixed prosthesis. Resul…

CTR: A calculus of timed refinement

1995

This paper presents CTR — a process algebraic framework for loose specification of time quantity sensitive operational behaviour of reactive systems. CTR terms are provided both with operational and specification semantics (via the notion of specification refinement). Besides the intuitive justification of appropriateness of the refinement notion, a preservation theorem is proved for a timed variant of Hennessy-Milner logic. A comparison of CTR with the related formalism of Timed Modal Specifications, and with the timed process calculi TCCS due to Wang is given. Some pragmatics of the application of CTR is sketched on a critical resource access example.

Impacto de la modalidad de diálisis sobre la morbimortalidad del paciente trasplantado tras el fracaso del injerto renal

2018

1. Introducción: El trasplante renal es el tratamiento de elección de la enfermedad renal crónica terminal mejorando la calidad de vida y la supervivencia del paciente en comparación con las otras alternativas de tratamiento sustitutivo renal. Gracias a los avances en las técnicas quirúrgicas, la inmunosupresión y el manejo global del paciente trasplantado la supervivencia del injerto a corto-medio plazo ha mejorado pero no así la supervivencia a largo plazo, por lo que sigue habiendo un alto porcentaje de pacientes cada año que vuelven a diálisis. Se desconoce en la actualidad cual es la mejor técnica de diálisis para esos pacientes. Por un lado, la libertad que les ha otorgado el trasplan…

Fusion of multimodal data by combining the uncertainty and perception models

2019

The general idea is to use together heterogeneous multiple information on the same problem tainted by imperfections and coming from several sources in order to improve the knowledge of a given situation. Appropriate visualization of the images to aid in decision making using the perceptual information carried by the salience maps.

QUANDO IL GESTO SI FA LINGUA
