Fractional differential equations and related exact mechanical models
2013
Creep and relaxation tests, performed on various materials like polymers, rubbers and so on are well-fitted by power-laws with exponent β ∈ [0, 1] (Nutting (1921), Di Paola et al. (2011)). The consequence of this observation is that the stress-strain relation of hereditary materials is ruled by fractional operators (Scott Blair (1947), Slonimsky (1961)). A large amount of researches have been performed in the second part of the last century with the aim to connect constitutive fractional relations with some mechanical models by means of fractance trees and ladders (see Podlubny (1999)). Recently, Di Paola and Zingales (2012) proposed a mechanical model that corresponds to fractional stress-…
Percepción del cambio climático en alumnado de 4º del Grado en Educación Primaria (Universidad de Valencia, España) a partir de la información de los…
2021
El cambio climático, sus causas y efectos suponen uno de los principales desafíos del siglo XXI. La enseñanza sobre este fenómeno constituye un reto para la formación de los/as futuros/as maestros/as de Primaria debido a la responsabilidad docente sobre la comprensión y posible adaptación a este fenómeno global. Los objetivos de este trabajo son: 1) Explorar y conocer los principales medios desde donde los/as futuros/as maestros/as de Primaria reciben información sobre el cambio climático; y 2) Reconocer las causas y consecuencias que se aluden en estos medios (según la percepción de los/as estudiantes) para identificar la concepción que se tiene sobre este fenómeno. A modo de estudio de ca…
The decision support system for telemedicine based on multiple expertise
1998
This paper discusses the application of artificial intelligence in telemedicine and some of our research results in this area. The main goal of our research is to develop methods and systems to collect, analyse, distribute and use medical diagnostics knowledge from multiple knowledge sources and areas of expertise. Use of modern communication tools enable a physician to collect and analyse information obtained from experts worldwide with the help of a decision support medical system. In this paper we discuss a multilevel representation and processing of medical data using a system which evaluates and exploits knowledge about the behaviour of statistical diagnostics methods. The presented te…
Cross-correlation and cross-power spectral density representation by complex spectral moments
2017
Abstract A new approach to provide a complete characterization of normal multivariate stochastic vector processes is presented in this paper. Such proposed method is based on the evaluation of the complex spectral moments of the processes. These quantities are strictly related to the Mellin transform and they are the generalization of the integer-order spectral moments introduced by Vanmarcke. The knowledge of the complex spectral moments permits to obtain the power spectral densities and their cross counterpart by a complex series expansions. Moreover, with just the aid of some mathematical properties the complex fractional moments permit to obtain also the correlation and cross-correlatio…
Computational Analysis Workshop: Comparing Four Approaches to Melodic Analysis
2009
We compare four computational approaches of melodic analysis according to diverse approach aspects: input type (monophonic or polyphonic), pattern identification type (strict or similar), analysis segmentation, aim of approach, motivic pattern representation, and type of result representations. The considered four computational approaches are the following: a similarity neighbourhood approach by Adiloglu (Adiloglu and Obermayer 2006a, b), a multiple viewpoint representation and discovery approach by Anagnostopoulou (Anagnostopoulou, Share and Conklin 2006), a topological approach by Buteau (2005), and an approach based on multidimensional closed pattern mining by Lartillot (Lartillot and To…
Motivic matching strategies for automated pattern extraction
2007
This article proposes an approach to the problem of automated extraction of motivic patterns in monodies. Different musical dimensions, restricted in current approaches to the most prominent melodic and rhythmic features at the surface level, are defined. The proposed strategy of detection of repeated patterns consists of an exact matching of the successive parameters forming the motives. We suggest a generalization of the multiple-viewpoint approach that allows a variability of the types of parameters (melodic, rhythmic, etc.) defining each successive extension of these motives. This enables us to take into account a more general class of motives, called heterogeneous motives, which inclu…
The content validity of the adult attachment interview. An empirical investigation using text analysis
2011
The aim of this study was to conduct a preliminary investigation of the content validity of the Adult Attachment Interview (AAI). Content validity is a series of hypothesis control methods relating to the communication of facts and it can be tested using several procedures of analytical decomposition (Rositi, 1988). In order to evaluate the content validity of a text, Sireci (1998), Sireci and Geisinger (1992, 1995), and Ding (2005) suggested the integration within this technique of multidimensional scaling and cluster analysis. The aim of this study was to conduct a preliminary investigation of the content validity of the AAI, as proposed in the literature. We hypothesized that participant…
Aesthetics of Geometry and the Problem of Representation in Monument Sculpture
2017
Since the 1920s and 1930s, constructivist and concretist visual art movements have stressed geometric forms, proportions and orders as a base for artistic expressions and aesthetic experiences. After the World War II geometric form was adopted to the public sculpture. Abstract, geometrically constructed sculpture was also used in commemorative functions in modern monument art. The combination of the commemoration of a significant historical event or a national hero, and the aesthetic ideas based on constructivist or concretist art movements caused a lot of debates and confrontations in many Western countries. In particular, the interpretation of abstract monuments problematized: abstract mo…
Henstock type integral in compact zero-dimensional metric space and quasi-measures representations
2012
Properties of a Henstock type integral defined on a compact zero-dimensional metric space are studied. Theorems on integral representation of so-called quasi-measures, i.e., linear functionals on the space of “polynomials” defined on the space of the above mentioned type, are obtained.
