Comparison between unrestricted dynamic shakedown design and a new probabilistic approach for structures under seismic loadings
2014
The paper concerns a study related to the comparison between two different approaches utilized for the formulation of an optimal shakedown design problem for elastic plastic frame structures subjected to a combination of fixed and seismic loading. The first formulation utilizes the unrestricted dynamic shakedown theory, while the second one is based on a new probabilistic approach. The comparison is effected in terms of mathematical formulations, in terms of adopted loading models and in terms of numerical results. The performed applications are related to plane steel frames.
AN EMPIRICAL ANALYSIS OF THE PUBLIC SPENDING DECOMPOSITION ON ORGANIZED CRIME
2016
The aim of this paper is to investigate, empirically, what components of the public spending imply a decreasing effect on the organized crime and what components create opportunities for the organized crime, discussing also the role of government effciency. The findings show a strikingly consistent pattern. Organized crime mainly operates in the distribution of the public spending for health, housing and community amenities. There is a decreasing effect on organized crime of the public expenditure devoted to education and to create morality values, such as the expenditure for recreation, culture and religion. Finally, government efficiency in public spending is beneficial for reducing the o…
Multi-objective parameter identification via ACOR algorithm
2009
The spreading of advanced constituive models, needed to model complex phenomena, makes necessary to solve difficult parameter identification problems. The need of multiple tests to fully characterize the experimental behaviour makes the parameter identification problem a multi objective one. Unlike conventional techniques, based on the formulation of an aggregate scalar ob- jective function, in the present work the problem is addressed using a new multi objective algorithm obtained extending the continuous Ant Colony Optimization algorithm. Mathematical tests and ap- plication to a real world problem are performed and different performance measures are used to asses the performance of the a…
Mostri e prodigi. La Sicilia e il meraviglioso
2019
Questo volume intende analizzare un singolo aspetto della sfera del prodigioso, relativo ai parti mostruosi. Come furono interpretati, quali le persistenze e le trasformazioni nei quadri culturali di riferimento? E perché la Sicilia? Ciò su cui il libro prova a interrogarsi pertiene a un ben preciso ambito: quanto la cultura medico-scientifica dell’isola, ma anche quella ermetica e magica, abbiano contribuito in età moderna al più ampio sviluppo del discorso sui mostri
Melt Processed PCL/PEG Scaffold with Discrete Pore Size Gradient for Selective Cellular Infiltration
2016
In order to develop scaffold able to mimic the natural gradient properties of tissues, biphasic and triphasic approaches were adopted. In this work, polycaprolactone/polyethylene glycol (PCL/PEG) scaffolds were prepared by using a combination of melt mixing and selective leaching without harmful solvents. The method permitted to develop three-layer scaffolds with high control of porosity and pore size. The mechanical properties were evaluated under physiological condition in order to simulate the real conditions of work. Co-culture of osteoblastic and fibroblastic mice cells were carried out in order to study the differential cellular permeation through the different pore size layers.
Design Of TLCD under random loads: a new formulation
2012
Computational Fluid Dynamics (CFD) and Finite Element Analysis (FEM) of a Customized Stent-Graft for Endovascular (EVAR) Treatment of Abdominal Aorti…
2023
Background: The treatment of abdominal aortic aneurysm (AAA) is today commonly treated by inserting a stent-graft by the endovascular route, without resorting to open surgery. However, some clinical cases do not allow this less invasive approach, meaning that the stent-graft cannot be inserted and open surgery is used. Methods: In the study, we propose a fluid–structure interaction (FSI) analysis of an aneurysmatic aorta that could not be treated with Endovascular Aneurysm Repair (EVAR). The vessel is reconstructed through segmentation from CT scans and subsequently modeled on CAD software to create the surface and thickness of the vessel itself. Subsequently, we proceeded to carry out Comp…
Fenomenologia della percezione. Modelli, mereologia, sperimentazione.
2012
La ricerca sulla percezione è oggetto di scienze e teorie filosofiche con metodi e impegni concettuali diversi. In questo saggio si tenta di ricostruire i caratteri condivisi dalle teorie concettuali e sperimentali della fenomenologia della percezione. Si sostiene che dai concetti e dalle scoperte dell’analisi e della sperimentazione fenomenologica sia possibile costruire modelli di funzioni percettive ben definite. Si presentano evidenze storiografiche e argomenti a sostegno della tesi che tali modelli contribuiscono alla ricerca sulla percezione condotta da altre scienze con diversi metodi, tecniche e costrutti. The research into perception is carried out by sciences and philosophical the…
Socioeconomic determinants of persistence in poor subjective health
2012
This paper aims at contributing to the constantly growing literature on the dynamics of (self assessed) health. Using the eight waves of the Health and Retirement Study, targeting elderly Americans over the age of 50, we measure persistence in bad health using an index borrowed from the literature on persistent poverty. This new approach, which is totally non parametric in the way it defines the relationship (for each individual and along the time) among years of poor and not poor health, allows to catch some interesting links between the subjective health and several factors such as education, life styles and socioeconomic status that may have a long-lasting influence on an individual’s he…
MATERIALS AND ARTISTIC TECHNIQUES OF THE FLEMISH WOODEN ALTAR FROM DEPOSITS OF ABATELLIS PALACE MUSEUM (PALERMO, ITALY)
2022
In the frame of the restoration intervention on a 16th century wooden altar performed by the experts of the Gallery of Art for the Sicilian Region ‘Palazzo Abatellis’, a deep scientific investigation of the artwork has been made by a scientific team in order to individuate the constitutive materials and techniques. The outcomes from the multi-analytical analyses supported the scheduling and monitoring of the conservation treatments and revealed the pictorial materials and underdrawing techniques typical of the artistic production for this typology of work of art widespread between the 15th and 16th centuries in central and northern Europe.
