Smartphone-based bridge monitoring through vehicle-bridge interaction: analysis and experimental assessment

2022

AbstractIn this study, the results of a vast experimental campaign on the applicability of a smartphone-based technique for bridge monitoring are presented. Specifically, the vehicle–bridge interaction (VBI)-based approach is exploited as a cost-effective means to estimate the natural frequencies of bridges, with the final aim of possibly developing low-cost and diffused infrastructure monitoring system. The analysis is performed using a common hybrid vehicle, fully equipped with classical piezoelectric accelerometers and a smartphone MEMS accelerometer, to record its vertical accelerations while passing over the bridge. In this regard, the experimental campaign is carried out considering t…

PROVA TECNICA E CONTRADDITTORIO NEL PROCESSO PENALE

2023

When science and the criminal process come into contact, cognitive mechanisms are set in motion aimed at reorganizing knowledge belonging to worlds other than the legal one. In this context, the actors of the trial scene are forced to move on a hybrid terrain in which judicial epistemology and scientific epistemology mix. Such a fascinating picture pushes the scholar of the criminal process to seek interpretations suitable for explaining the multiple dilemmas that the phenomenon entails. Starting from a historical-legislative excursus of the expert evidence, the proposed analysis examines the different channels through which expert knowledge enters the process, starting from the investigati…

Data concerning the protein absorption and retention properties of xyloglucan-based hydrogel film

2018

In wound dressing applications, exudate absorption and retention are important properties. The data presented here assess the ability of the crosslinked xyloglucan-poly(vinyl alcohol) hydrogel films (XG-PVA), described in "Xyloglucan-based hydrogel films for wound dressing: Structure-property relationships" (Ajovalasit et al., 2018) [1] and "Biocompatibility, hemocompatibility and antimicrobial properties of xyloglucan-based hydrogel film for wound healing application" (Picone et al., 2019), to absorb and retain proteins. These properties were investigated by Comassie blue staining and electrophoresis of Fetal Serum Proteins. (C) 2018 The Authors. Published by Elsevier Inc. This is an open …

Surface processes in selective photocatalytic oxidation of hydroxybenzyl alcohols by TiO2 P25

2023

Aryl aldehydes and acids are important industrial intermediates, but their synthesis from the corresponding alcohols often requires the use of high temperatures and harmful solvents and oxidant agents. Heterogeneous photocatalysis represents an interesting option for the partial oxidation of alcohols to aldehydes at room temperature using water as solvent. In this work, the partial photocatalytic oxidation of 2-hydroxybenzyl alcohol (salicyl alcohol) and 4-hydroxybenzyl alcohol to the corresponding aldehydes and acids has been compared, under environmental-friendly conditions, employing TiO2 P25 as photocatalyst in water. The selectivity to the corresponding aldehydes and acids, under the s…

Surface characterization of metal ions loaded TiO2 photocatalysts: structure-activity relationship

2004

Transition metal loaded TiO2 powders were characterised and tested for the photodegradation of some organic acids. Both Lewis and Brønsted surface acid sites were present in the samples containing large amounts of Mo, V and W. The Brønsted sites are associated to the presence of the transition metals as they do not exist in the unloaded support, and in particular to the presence of these metals in high oxidation states. The trend of the pzc values of the various powders matches rather well both with the surface acidity of the samples experimentally determined by NH3 adsorption and with a scale of acidity/basicity for bulk binary oxides. XPS investigation indicates that only the presence of …

Detection of the Lowest-Lying Odd-Parity Atomic Levels in Actinium

2020

Two lowest-energy odd-parity atomic levels of actinium, 7s27pP21/2o, 7s27pP23/2o, were observed via two-step resonant laser-ionization spectroscopy and their respective energies were measured to be 7477.36(4) and 12 276.59(2) cm-1. The lifetimes of these states were determined as 668(11) and 255(7) ns, respectively. In addition, we observed the effect of the hyperfine structure on the line for the transition to P23/2o. These properties were calculated using a hybrid approach that combines configuration interaction and coupled-cluster methods, in good agreement with the experiment. The data are of relevance for understanding the complex atomic spectra of actinides and for developing efficien…

A symmetric Galerkin boundary/domain element method for finite elastic deformations

2000

Abstract The Symmetric Galerkin Boundary Element Method (SGBEM) is reformulated for problems of finite elasticity with hyperelastic material and incompressibility, using fundamental solutions related to a (fictitious) homogeneous isotropic and compressible linear elastic material. The proposed formulation contains, besides the standard boundary integrals, domain integrals which account for the problem's nonlinearities through some (fictitious) initial strain and stress fields required to satisfy appropriate “consistency” equations. The boundary/domain integral equation problem so obtained is shown to admit a stationarity principle (a consequence of the Hu-Washizu one), which covers a number…

L’integrazione dei Musulmani in Europa e la circolazione della banca e della finanza islamica (Integration of Muslims in Europe and Circulation of Is…

2018

Italian Abstract: Lo stabilizzarsi di comunita islamiche all'interno dell'Unione Europea impone l'attenzione sulle peculiarita legate alla realta islamica. Lo “spazio della sharī'a”, infatti, lungi dal confinarsi nel medio oriente si estende all'Unione Europea attraverso i luoghi di lavoro, le scuole, gli ospedali, i tribunali e i mercati. All’espansione dei modelli normativi islamici hanno contribuito, in particolare, le politiche di “ristrutturazione” dell'ordinamento islamico degli anni '80 del secolo scorso e l'intensificarsi dei flussi migratori a partire degli anni '90, creando un terreno fertile al dispiegarsi delle potenzialita della sharī'a a livello transnazionale, offrendo a sogg…

BEM application on an external problem comparison with both theoretical and finite elements results and observations on divergence strip

1992

Abstract By means of a computer program the Boundary Element Method is applied to a central hole in an undefined plate with uniform load along the boundary. Results are compared with those obtained by Kirsch's theoretical solution and a previous analysis by the Finite Element Method. The calculus of percentage error shows the advantage of the Boundary Element Method on the external problem with regard to the Finite Element Method. The error causes near the boundary internal points are analysed with the existence of a strip, where the result is not reliable in evidence.
