Thresholding projection estimators in functional linear models
2008
We consider the problem of estimating the regression function in functional linear regression models by proposing a new type of projection estimators which combine dimension reduction and thresholding. The introduction of a threshold rule allows to get consistency under broad assumptions as well as minimax rates of convergence under additional regularity hypotheses. We also consider the particular case of Sobolev spaces generated by the trigonometric basis which permits to get easily mean squared error of prediction as well as estimators of the derivatives of the regression function. We prove these estimators are minimax and rates of convergence are given for some particular cases.
A Unified SVM Framework for Signal Estimation
2013
This paper presents a unified framework to tackle estimation problems in Digital Signal Processing (DSP) using Support Vector Machines (SVMs). The use of SVMs in estimation problems has been traditionally limited to its mere use as a black-box model. Noting such limitations in the literature, we take advantage of several properties of Mercer's kernels and functional analysis to develop a family of SVM methods for estimation in DSP. Three types of signal model equations are analyzed. First, when a specific time-signal structure is assumed to model the underlying system that generated the data, the linear signal model (so called Primal Signal Model formulation) is first stated and analyzed. T…
On differences and similarities in the analysis of Lorenz, Chen, and Lu systems
2015
Currently it is being actively discussed the question of the equivalence of various Lorenz-like systems and the possibility of universal consideration of their behavior (Algaba et al., 2013a,b, 2014b,c; Chen, 2013; Chen and Yang, 2013; Leonov, 2013a), in view of the possibility of reduction of such systems to the same form with the help of various transformations. In the present paper the differences and similarities in the analysis of the Lorenz, the Chen and the Lu systems are discussed. It is shown that the Chen and the Lu systems stimulate the development of new methods for the analysis of chaotic systems. Open problems are discussed.

The Blind Bard and the Unflagging Hierarch: Memories of War and Self-Representations in Fascist Italy
2013
The aim of this paper is to study two different and conflicting memories of the Great War developed in fascist Italy. In particular, an attempt will be made to focus on the cases of Carlo Delcroix and Roberto Farinacci. They were both born in 1890’s and took part in the war, during which Delcroix was severely mutilated. Alongside the few traits they had in common, many differences divided their political lives. Farinacci soon joined Fascism, became one of the leaders of the radical wing and, in the second half of 1930s, supported the alliance with Nazi Germany. Delcroix, who led one of the most important veterans associations, defined himself in the public debate mainly as a war invalid and…

Il trattato L’Amore e la «legge dell’egoismo universale»: il positivismo inquieto di Federico De Roberto
2018
L’Amore. Fisiologia – Psicologia – Morale is probably the highest level of De Roberto’s ideology, and at same time it may be considered as a turning point in the poetic of this author. De Roberto lives in a Positivist age, and he deeply trusts in the instrument of reason. In this work he aims to demonstrate all the contradictions of love and the egoism of the social life. So, De Roberto arrives to a uneasy Positivism, which is focused not only on the “how” of the phenomena, but also to the “why”. Under this point of view, De Roberto’s relativism is similar to that one of Pirandello, and it announces the incoming Modernism. Even if it is impossible to join the truth, De Roberto doesn’t quit …
Felisberto y Macedonio: estrategias de deconstrucción entre humorístico y fantástico
2017
Basta con adentrarse unas pocas líneas en la obra de Felisberto Hernández, para intuir, percibir, un profundo misterio, como si en cada frase se escondieran las raíces de un entero imaginario poético. Sería restrictivo referirse a una extraordinaria densidad de la escritura para evocar la continua y embriagadora presencia de imágenes y sugestiones que desplazan al lector y lo envuelven en un vórtice de inéditas asociaciones de ideas, de objetos cotidianos que adquieren una existencia profunda, o de acciones simples que a través de una mirada nueva e íntima sobre el mundo se transforman en aventuras oníricas extraordinarias. Una peculiar concepción del genero fantástico rige y multiplica la …
