Dynamic characterization and FE model updating via metaheuristic algorithm of two confined masonry buildings

This paper investigates the dynamic characteristics and Finite element model updating of two confined masonry buildings in Messina, constructed in the aftermath of the devastating 1908 earthquake. The study addresses the need for advanced research in this field to enhance the understanding of the dynamic behaviour of confined masonry structures. The authors identified the modal parameters of the buildings from ambient vibration tests. Finite element models have been developed and fine-tuned i...

Investigating and monitoring central nave vaults of the Turin Cathedral with Acoustic Emissions and Thrust Network Analysis

Ancient masonry constructions and historical buildings, such as cathedrals, are exposed to considerable risks attributed to factors like ageing and long-term exposure to both dynamic and static variations in loading conditions. In this study, an innovative and promising monitoring approach was applied to assess the structural integrity of the vault in the central nave of the Turin Cathedral. Specifically, the outcomes obtained from Acoustic Emissions (AE) are correlated with the insights deri...

Reconciling Kozlov’s vakonomic method with the traditional non-holonomic method: solution of two benchmark problems

We study the dynamics of a class of mechanical systems subjected to non-holonomic constraints by employing a method termed “modified vakonomic method” (MVM), and developed by Llibre, Ramírez and Sadovskaia in 2014. In particular, we test the MVM for the “rolling coin” problem and a variant of the “non-holonomic skate” problem. For our purposes, we divide our work in two parts. For the first one, our point of departure is a paper published in this journal by Lemos in 2022, in which, for th...

Rational Normal Curves and Hadamard Products

Given r > n general hyperplanes in P-n, a star configuration of points is the set of all the n-wise intersection of the hyperplanes. We introduce contact star configurations, which are star configurations where all the hyperplanes are osculating to the same rational normal curve. In this paper, we find a relation between this construction and Hadamard products of linear varieties. Moreover, we study the union of contact star configurations on a same conic in P-2, we prove that the union of tw...

A reduced variable neighborhood search for the just in time job shop scheduling problem with sequence dependent setup times

In this paper, we deal with the just-in-time job shop scheduling problem with sequence-dependent setup times and release dates. Given a set of jobs characterized by release and due dates, the goal is to execute them by minimizing a weighted sum of their earliness, tardiness, and flow time (i.e., the difference between completion and start time of each job). We develop new destroy and repair operators by exploiting the structure of the problem, and we use them within a reduced variable neighbo...
