Smoothed Particle Electromagnetics Modelling on HPC-GRID Environment
2012
In this paper a meshless approach on a high performance grid computing environment to run fast onerous electromagnetic numerical simulations, is presented. The grid computing and the message passing interface standard have been employed to improve the computational efficiency of the Smoothed Particle Electromagnetics meshless solver adopted. Applications involving an high number of particles can run on a grid computational environment simulating complex domains not accessible before and offer a promising approach for the coupling of particle models to continuous models. The used meshless solver is straightforward to program and fully parallelizable. The results of the parallel numerical sch…

On a regularized approach for the method of fundamental solution
2018
The method of fundamental solution is a boundary meshless method recently adopted in the framework of non-invasive neu- roimaging techniques. The method approximates the solution of a BVP by a linear combination of fundamental solutions of the governing PDE. A crucial feature of the method is the placement of the fictitious boundary to avoid the singularities of fundamental solutions. In this paper we report on our experiences with a regularized MFS method in the neuroimaging context.
Analysis of the Allee threshold via moving least square approximation
2016
Cooperation is a common behavior between the members of predators species, because it can improve theirs skill in hunt, especially in endangered eco-systems. This behavior it is well known to induce the Strong Allee effect, that can induce the extinction when the initial populations’ is under a critical density called ”Allee threshold ”. Here we investigate the impact of the pack hunting in a predator-prey system in which the predator suffers of an infectious disease with frequency and vertical transmission. The result is a three dimensional system with the predators population divided into susceptible and infected individuals. Studying the system dynamics a scenario was identified in which…

Case report: esiti di crush syndrome complicata da poliradicolonevrite
2013
LOa crush syndrome o rabdomiolisi traumatica è una patologia conseguente a compressione prolungata (h 4-6) su uno o più arti ed è caratterizzata da shock ipovolemico e blocco renale conseguenti ad una lesione da schiacciamento a carico di più muscoli. questo case report si propone di descrivere la presa in carico riabilitativa di un soggetto affetto da crush syndrome, associata a lesione completa del plesso brachiale destro, incompleta di quello sinistro e poliradicolonevrite di Guillan-Barrè.

Riflessività, interazione e rispetto delle norme. Il contributo dei mixed methods tra analisi dei testi e social network analysis
2018
The book, through a special methodological mix that uses text analysis and social network analysis, explores the ways in which people, starting from some elements considered implicit, are able to problematize specific behaviours. People contribute differently to social change or reproduction, by selecting certain aspects of reality and attributing to these aspects power of constraint or facilitation. Starting from the theoretical approach of Margaret Archer, which looks at the reflexivity of social actors as the capacity to develop an internal conversation, which is able to mediate between structure and agency, the book deals with the dynamics that take place when reflexive types converse o…
