Diritti fondamentali e principio di proporzionalità
2014
the paper assesses the widespread use of the test of proportionality in fundamental rights adjudication. While constitutional and human rights courts all over the world appear to be consistently engaged in deploying the test of proportionality in order to assess the permissibility of a given rights limitation, this approach is under severe criticism insofar as it is considered an attack to the very idea of fundamental rights. The paper will discuss this criticism of the use of proportionality, and will provide a defense of its use by courts in light of some basic features of the contemporary discourse of fundamental rights.
A fixed point theorem for uniformly locally contractive mappings in a C-chainable cone rectangular metric space
2011
Recently, Azam, Arshad and Beg [ Banach contraction principle on cone rectangular metric spaces, Appl. Anal. Discrete Math. 2009] introduced the notion of cone rectangular metric spaces by replacing the triangular inequality of a cone metric space by a rectangular inequality. In this paper, we introduce the notion of c-chainable cone rectangular metric space and we establish a fixed point theorem for uniformly locally contractive mappings in such spaces. An example is given to illustrate our obtained result.
Polynomial mapped bases: theory and applications
2022
Abstract In this paper, we collect the basic theory and the most important applications of a novel technique that has shown to be suitable for scattered data interpolation, quadrature, bio-imaging reconstruction. The method relies on polynomial mapped bases allowing, for instance, to incorporate data or function discontinuities in a suitable mapping function. The new technique substantially mitigates the Runge’s and Gibbs effects.
Sex and Sexuality
2021
Abstract Symbolic interactionist approaches to sexuality state that human beings become sexual as they become whatever else and learn sexual definitions and sexual meanings just like they learn any other kind of meaning. Therefore, interactionist analysis shifts the focus of inquiry into sex from being sexual towards becoming sexual, which takes into account how sexualities are produced, organized, and negotiated, rather than tracing their sources in an immutable (conception of) nature. Sociosexual meanings give people the chance to define themselves and others sexually, to construct their sexual self and doing sexual things together in the shaping of more complex sexual choreographies and …
Education on Sexual Diversity through Cinema
2014
Abstract Our proposal raises the urgency to include the defense of sexual diversity in the curriculum of Art Education. We provide visibility mechanisms to sexual minorities in personal and social order, and propose an approach to the subject, especially in training teachers. From aesthetic reflection we must foster a new critical look at Media Education. We should encourage future teachers to address these issues in their classes, appropriating the use and content of images. A topical issue such as the promotion of respect for sexual diversity has on films perfect ally. Suggest ideas about educational processes through a series of examples. From cinema and visual art can introduce reflecti…
Incoherent dispersive shocks in the spectral evolution of random waves
2013
We predict theoretically and numerically the existence of incoherent dispersive shock waves. They manifest themselves as an unstable singular behavior of the spectrum of incoherent waves that evolve in a noninstantaneous nonlinear environment. This phenomenon of "spectral wave breaking" develops in the weakly nonlinear regime of the random wave. We elaborate a general theoretical formulation of these incoherent objects on the basis of a weakly nonlinear statistical approach: a family of singular integro-differential kinetic equations is derived, which provides a detailed deterministic description of the incoherent dispersive shock wave phenomenon.
Channel Gain Cartography via Mixture of Experts
2020
In order to estimate the channel gain (CG) between the locations of an arbitrary transceiver pair across a geographic area of interest, CG maps can be constructed from spatially distributed sensor measurements. Most approaches to build such spectrum maps are location-based, meaning that the input variable to the estimating function is a pair of spatial locations. The performance of such maps depends critically on the ability of the sensors to determine their positions, which may be drastically impaired if the positioning pilot signals are affected by multi-path channels. An alternative location-free approach was recently proposed for spectrum power maps, where the input variable to the maps…
Learning Automata Based Q-learning for Content Placement in Cooperative Caching
2019
An optimization problem of content placement in cooperative caching is formulated, with the aim of maximizing sum mean opinion score (MOS) of mobile users. Firstly, a supervised feed-forward back-propagation connectionist model based neural network (SFBC-NN) is invoked for user mobility and content popularity prediction. More particularly, practical data collected from GPS-tracker app on smartphones is tackled to test the accuracy of mobility prediction. Then, a learning automata-based Q-learning (LAQL) algorithm for cooperative caching is proposed, in which learning automata (LA) is invoked for Q-learning to obtain an optimal action selection in a random and stationary environment. It is p…
Cubic Local Splines on Non-uniform Grid
2015
In this chapter, two types of local cubic splines on non-uniform grids are described: 1. The simplest variation-diminishing splines and 2. The quasi-interpolating splines. The splines are computed by a simple fast computational algorithms that utilizes a relation between the splines and cubic interpolation polynomials. Those splines can serve as an efficient tool for real-time signal processing. As an input, they use either clean or noised arbitrarily-spaced samples. On the other hand, the capability to adapt the grid to the structure of an object and minimal requirements to the operating memory are great advantages for off-line processing of signals and multidimensional data arrays.
