Adaptive Metropolis algorithm using variational Bayesian adaptive Kalman filter

2013

Markov chain Monte Carlo (MCMC) methods are powerful computational tools for analysis of complex statistical problems. However, their computational efficiency is highly dependent on the chosen proposal distribution, which is generally difficult to find. One way to solve this problem is to use adaptive MCMC algorithms which automatically tune the statistics of a proposal distribution during the MCMC run. A new adaptive MCMC algorithm, called the variational Bayesian adaptive Metropolis (VBAM) algorithm, is developed. The VBAM algorithm updates the proposal covariance matrix using the variational Bayesian adaptive Kalman filter (VB-AKF). A strong law of large numbers for the VBAM algorithm is…

Supercapacitor diagnosis using an Extended Kalman Filtering approach

2016

This paper deals with the model-based analysis of a Supercapacitor for diagnostic purposes. A two legs nonlinear physical model is assumed for the Supercapacitor and the corresponding second-order nonlinear state-space mathematical model is obtained. Then, an Extended Kalman Filter is tuned so that the estimated outputs reproduce the voltages at the equivalent capacitance terminals; they give information on the state of health of the supercapacitor but are not directly measurable. In particular, an optimization problem is firstly formulated, involving the experimental input-output data and those given by the Extended Kalman Filter.

Diagnostic of Supercapacitors based on State Estimation through Extended Kalman Filter

This thesis aimed to analyze the supercapacitor behavior to verify the possibility of the estimation of its internal parameters for diagnostic purposes. The target has been reached firstly by a theoretical analysis which showed that the crucial parameters for diagnostic purposes are the voltage of the non-linear capacitance, since it gives a measure of the stored charge, and the parasitic resistance which limits the maximum allowable current and influences losses. Secondly it has been verified when a supercapacitor parameters are observable and finally an extended Kalman filter to obtain such parameters has been set up. The Thesis demonstrated that a supercapacitor can be modelled by a 2-br…

Sobre De somniís liber de Augerius Ferrerius

2004

E-mail @uv.es: privado (a solicitud del interesado) En este libro Ferrer, en plena época renacentista, hace compatibles las teorías oníricas de los autores griegos con sus principios y punto de vista cristianos. Niega tajantemente que existan ensueños vanos y se interesa por los ensueños naturales, cuya génesis está en el estado psicofísico del individuo. Pero, sobre todo, presta su máxima atención a los ensueños divinos. Establece normas para distinguir éstos de los enviados por los malos espíritus. Afirma que ha descubierto mediante la razón y la propia experiencia claves para la interpretación de los ensueños que los filósofos anteriores no llegaron a descubrir. In this book, published d…

Terremoto e ricostruzione a Ragusa nel 1520

2012

L'articolo traccia un sintetico quadro dei danni riportati dal patrimonio architettonico della repubblica di Ragusa in Dalmazia in occasione del terremoto che la colpì nel 1520, analizzando le modalità di gestione dell'emergenza e i cantieri di ricostruzione avviati dopo il sisma.

An Investigation of the Robustness in the Travelling Salesman Problem Routes Using Special Structured Matrices

2020

In this study, the robustness of the Travelling Salesman Problem (TSP) routes is investigated by recognising the special combinatorial structures of Kalmanson matrices. A recognition algorithm encompassing three procedures based on combinatorial and linear programming (LP) is developed and executed on several randomly generated instances. These procedures produce three lower bounds which provide guarantees on the optimality of the solutions. Computational experiments show that the proposed LP-based procedure performs efficiently well across all problem dimensions and provides the best lower bounds to the TSP. This is supported by an average deviation of less than 7% between the TSP tour len…

La fraseologia com a tret estilístic en novel·les originals en anglés i les seues traduccions al català

2018

This paper is an analysis of the stylistic function of phraseology in three contemporary novels, originally written in English —Enduring Love, by Ian McEwan; The Road, by Cormac McCarthy; and Midnight’s Children, by Salman Rushdie—, and their corresponding translations into Catalan —Amor perdurable, La carretera and Els fills de la mitjanit. Taking into account some theoretical reflections on phraseology and translation, and by comparing the original novels and their translations, in this article we analyze some examples of phraseological units (PUs) that play a significant stylistic role and we also examine the techniques used by professional translators when faced with this sort of PUs.
