Aprendizaje basado en proyectos en los laboratorios de comunicaciones digitales
2019
[EN] Digital Communications and Signal Processing for Communications have been traditionally taught from a theoretical point of view. The complexity and cost of radio-frequency systems hampers the realization of practical experiences in the laboratories of Communications. However, current Academic Accreditation includes the dimension of “what students are expected to be able to do”. The decrease of the gap between standard simulated laboratory sessions and more practical and realistic approaches is therefore required. In this paper, we introduce an active learning methodology we have followed in order to introduce practical aspects related to Digital Communications and Signal Processing for…
Application of action camera video for fast and low-cost photogrammetric survey of cultural heritage
2022
Abstract. The research work focuses on the growing of fast and low-cost data surveying methods (both in the acquisition and processing phases), to be used mainly as a support for the management and enhancement of architectural heritage. Attention is paid on the diffusion of action cameras, characterized by wide-angle lenses and 4K video shooting, with more and more affordable prices and on the elaboration of the data with photogrammetry software. The high-resolution videos captured by these tools, in fact, allow the selection of frames characterized by sufficient overlap, necessary for point cloud generation through Structure for Motion (SfM) processes. The focus is on indoor environment ch…

Ronald Dworkin e il positivismo giuridico: un bilancio provvisorio
2014
The controversy between Dworkin and legal positivism has lasted more than forty years. After Dworkin’s death, a reflection on this debate is needed. This paper faces some of the most important and popular arguments Dworkin advanced against legal positivism. More precisely, the article is divided in two main parts. The first is devoted to a critical presentation of three arguments developed by Dworkin in his early essays against Hart’s practice theory of norms. In particular, these arguments challenge a) the idea that law is a system of rules; b) the autonomy of legal obligation from moral one and c) the idea that judges exercise (strong) discretion in hard cases. The second part analyses tw…
Some diffusion equations with finite propagation speed
2007
We summarize some of our recent results on diffusion equations with finite speed of propagation. These equations have been introduced to correct the infinite speed of propagation predicted by the classical linear diffusion theory. (© 2008 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
1D antiferromagnetism in spin‐alternating bimetallic chains
1990
The magnetic and thermal properties of the ordered bimetallic chain CoNi(EDTA)⋅6H2O in the very low‐temperature range are reported. The magnetic behavior does not exhibit the characteristic features of 1D ferrimagnets, but a continuous decrease of χmT towards zero at absolute zero. This 1D antiferromagnetic behavior results from an accidental compensation between the moments located at the two sublattices. This behavior, as well as the specific‐heat results, are modeled on the basis of an Ising‐exchange model that considers both alternating spins and Landé factors, and a zero‐field splitting on the Ni site.

Magnetism and EPR spectra of the two‐sublattice manganese chain Mn2(EDTA)⋅9H2O
1990
We report on the magnetic behavior and single‐crystal EPR spectra of the chain complex Mn2(EDTA)⋅9H2O characterized by two different alternating sites for the manganese ions. Magnetic susceptibility data are indicative of weak antiferromagnetic exchange interactions between the manganese ions, showing a maximum of about 3 K. This behavior can be accurately described on the basis of a Heisenberg chain model that assumes classical spins, giving J/k=−0.72 K and g=2.0. The EPR spectra are typically low dimensional, with an angular dependence of the linewidth of the type (3 cos2 θ−1)n (n=4/3 or 2). Nevertheless, such a behavior cannot be reproduced from a one‐dimensional model with dipolar broad…
Associations between sexual activity and weight status: Findings from the English Longitudinal Study of Ageing.
2019
Objective To investigate the association between weight status and sexual activity in middle-aged and older adults. Methods Cross-sectional analysis on Wave 6 (2012/13) of the English Longitudinal Study of Ageing. Data were from 2,200 men and 2,737 women aged ≥50 years (mean 68.2 years). The explanatory variable was weight status, defined as normal-weight (BMI: ≤24.9), overweight (BMI: 25.0–29.9) or obese (BMI: ≥30) based on objective measurements of height and weight. Outcome variables were any self-reported sexual activity in the last year (yes/no) and, if yes, frequency of sexual intercourse in the last month. Covariates included a range of sociodemographic, lifestyle, and health-related…
