Computational Homogenization of Heterogeneous Materials by a Novel Hybrid Numerical Scheme

2020

The Virtual Element Method (VEM) is a recent numerical technique capable of dealing with very general polygonal and polyhedral mesh elements, including irregular or non-convex ones. Because of this feature, the VEM ensures noticeable simplification in the data preparation stage of the analysis, especially for problems whose analysis domain features complex geometries, as in the case of computational micro-mechanics problems. The Boundary Element Method (BEM) is a well known, extensively used and effective numerical technique for the solution of several classes of problems in science and engineering. Due to its underlying formulation, the BEM allows reducing the dimensionality of the proble…

The Elephant in the Machine: Proposing a New Metric of Data Reliability and its Application to a Medical Case to Assess Classification Reliability

2020

In this paper, we present and discuss a novel reliability metric to quantify the extent a ground truth, generated in multi-rater settings, as a reliable basis for the training and validation of machine learning predictive models. To define this metric, three dimensions are taken into account: agreement (that is, how much a group of raters mutually agree on a single case)

Evaluation of the registration of temporal series of contrast-enhanced perfusion magnetic resonance 3D images of the liver.

2011

The registration of 2D and 3D images is one of the key tasks in medical image processing and analysis. Accurate registration is a crucial preprocessing step for many tasks; consequently, the evaluation of its accuracy becomes necessary. Unfortunately, this is a difficult task, especially when no golden pattern (true result) is available and when the signal values may have changed between successive images to be registered. This is the case this paper deals with: we have a series of 3D images, magnetic resonance images (MRI) of the liver and adjacent areas that have to be registered. They have been taken while a contrast is diffused through the liver tissue, so intensity of each observed poi…

Diffusional Kurtosis Imaging in the Diffusion Imaging in Python Project

2021

ABSTRACTDiffusion-weighted magnetic resonance imaging (dMRI) measurements and models provide information about brain connectivity and are sensitive to the physical properties of tissue microstructure. Diffusional Kurtosis Imaging (DKI) quantifies the degree of non-Gaussian diffusion in biological tissue from dMRI. These estimates are of interest because they were shown to be more sensitive to microstructural alterations in health and diseases than measures based on the total anisotropy of diffusion which are highly confounded by tissue dispersion and fiber crossings. In this work, we implemented DKI in the Diffusion in Python (DIPY) project - a large collaborative open-source project which …

Personality, occupational sorting and routine work

2020

Purpose – A prominent labour market feature in recent decades has been the increase in abstract and service jobs, while the demand for routine work has declined. This article examines whether the components of Type A behaviour predict workers’ selection into nonroutine abstract, non-routine service and routine jobs. Design/methodology/approach – Building on the work by Barrick et al. (2013), this article first presents how the theory of purposeful work behaviour can be used to explain how individuals with different levels of Type A components sort into abstract, service and routine jobs. Then, using longitudinal data, it examines whether the components of Type A behaviour predict occupation…

Knowledge and Mistakes

2015

This chapter is about how we attain knowledge, and how we fail to do so. I argue that a true thought counts as a piece of knowledge if and only if it has the right sort of causal history. I also argue that these so-called cognitive thoughts are the criteria of truth in the sense that they are guaranteed to be true and able to guarantee the truth of that which can be inferred from them. So I argue that there are three kinds of knowledge, namely the information conveyed by our senses, the information contained in our preconceptions and the conclusions that can be inferred from our sense-perceptions and our preconceptions. I then argue that we fail to attain knowledge if we assent to a thought…

Storicità del diritto. Strutture costituzionali, fonti, codici. Prospettive romane e moderne

2018

L’intento sotteso alla realizzazione del presente volume è quello di ripercorrere sinteticamente i tratti fondamentali della storia costituzionale romana individuando, al contempo, forme concettuali e prassi consolidate che - seppur sviluppate in quell’esperienza storica - hanno segnato anche le sorti di tutta la Tradizione giuridica successiva, e pertanto, dell’intera Tradizione giuridica Occidentale . Si tratta, infatti, di uno «strato tenacissimo di concetti e pratiche» che hanno raggiunto «quei laboratori politici e istituzionali dei cui prodotti siamo diretti eredi», secondo un percorso di «lunghissima portata e tendenzialmente universale ». Le forme concettuali del diritto romano sono…
