Active Learning for Imbalanced Civil Infrastructure Data

Ioana Giurgiu, Adelmo Cristiano Innocenza Malossi, Diego Matteo Antognini

Aging civil infrastructures are closely monitored by engineers for damage and critical defects. As the manual inspection of such large structures is costly and time-consuming, we are working towards fully automating the visual inspections to support the pr ...

Numerical comparison and calibration of geometrical multiscale models for the simulation of arterial flows

Adelmo Cristiano Innocenza Malossi, Jean Bonnemain

Arterial tree hemodynamics can be simulated by means of several models of different level of complexity, depending on the outputs of interest and the desired degree of accuracy. In this work, several numerical comparisons of geometrical multiscale models a ...

Implicit coupling of one-dimensional and three-dimensional blood flow models with compliant vessels

Alfio Quarteroni, Simone Deparis, Paolo Crosetto, Adelmo Cristiano Innocenza Malossi

Simulating arterial trees in the cardiovascular system can be made by the help of different models, depending on the outputs of interest and the desired degree of accuracy. In particular, one-dimensional fluid-structure interaction models for arteries are ...

On the continuity of mean total normal stress in geometrical multiscale cardiovascular problems

Simone Deparis, Adelmo Cristiano Innocenza Malossi

In this work an iterative strategy to implicitly couple dimensionally-heterogeneous blood flow models accounting for the continuity of mean total normal stress at interface boundaries is developed. Conservation of mean total normal stress in the coupling o ...

Numerical simulation of left ventricular assist device implantations: comparing the ascending and the descending aorta cannulations

Alfio Quarteroni, Simone Deparis, Ludwig Von Segesser, Adelmo Cristiano Innocenza Malossi, Jean Bonnemain, Matteo Lesinigo

In this work we present numerical simulations of continuous flow left ventricle assist device implantation with the aim of comparing the ascending and the descending aorta anastomosis of outflow cannula. Despite the fact that the second approach is less in ...

Partitioned Solution of Geometrical Multiscale Problems for the Cardiovascular System : Models, Algorithms, and Applications

Adelmo Cristiano Innocenza Malossi

The aim of this work is the development of a geometrical multiscale framework for the simulation of the human cardiovascular system under either physiological or pathological conditions. More precisely, we devise numerical algorithms for the partitioned so ...

A two-level time step technique for the partitioned solution of one-dimensional arterial networks

Simone Deparis, Adelmo Cristiano Innocenza Malossi

In this work a numerical strategy to address the solution of the blood flow in one-dimensional arterial networks through a topology-based decomposition is presented. Such decomposition results in the local analysis of the blood flow in simple arterial segm ...

An ALE-based numerical technique for modeling sedimentary basin evolution featuring layer deformations and faults

Alfio Quarteroni, Adelmo Cristiano Innocenza Malossi, Andrea Villa

In this paper we present a numerical tool to simulate dynamics of stratified sedimentary basins, i.e. depressions on the Earth’s surface filled by sediments. The basins are usually complicated by crustal deformations and faulting of the sediments. The bala ...

Algorithms for the partitioned solution of weakly coupled fluid models for cardiovascular flows

Alfio Quarteroni, Simone Deparis, Adelmo Cristiano Innocenza Malossi

The main goal of this work is to devise robust iterative strategies to partition the solution of the Navier-Stokes equations in a three-dimensional (3D) domain, into non overlapping 3D subdomains, which communicate through the exchange of averaged/integrat ...
