Martinelli, Cristiano (author), Coraddu, A. (author), Cammarano, Andrea (author)Meta-heuristic optimisation algorithms are high-level procedures designed to discover near-optimal solutions to optimisation problems. These strategies can efficiently explore the design space of the problems; therefore, they perform well even when incomplete and scarce information is available. Such characteristics make them the ideal...conference paper 2024

Pontani, Nicola (author), Martinelli, Luca (author), Acquati, Marco (author), Jommi, C. (author)Ground borne vibrations generated by the passage of underground trains may change over time due to objective causes, such as increasing weight and speed of trains or ageing of the infrastructure components, as well as a variation in the dynamic response of the soil surrounding the tunnel. Among the possible causes of changes in the soil...journal article 2023

Yost, Kaleigh M. (author), Martinelli, M. (author), Yerro, Alba (author), Green, Russell A. (author), de Lange, Dirk A. (author)Cone penetrometer tests (CPTs) are used to characterize soil for a variety of geotechnical engineering applications, including earthquake-induced liquefaction triggering assessment. Numerical modeling of CPTs is frequently used to better understand soil behavior, soil-penetrometer interaction, and engineering estimates made from CPT data....journal article 2023

Martinelli, Cristiano (author), Coraddu, A. (author), Cammarano, Andrea (author)In the industry field, the increasingly stringent requirements of lightweight structures are exposing the ultimately nonlinear nature of mechanical systems. This is extremely true for systems with moving parts and loose fixtures which show piecewise stiffness behaviours. Nevertheless, the numerical solution of systems with ideal piecewise...journal article 2023

Di Perna, Angela (author), Cuomo, Sabatino (author), Martinelli, M. (author)Full understanding the interaction mechanisms between flow-like landslides and the impacted protection structures is an open issue. While several approaches, from experimental to numerical, have been used so far, it is clear that the adequate assessment of the hydromechanical behaviour of the landslide body requires both a multiphase and...journal article 2022

Cuomo, Sabatino (author), Di Perna, Angela (author), Martinelli, M. (author)A full understanding of the interaction mechanisms among flow-like landslides and impacted protection structures is still an open issue. Although several approaches, from experimental to numerical, have been used so far, a thoroughly assessment of the hydromechanical behaviour of the landslide body is achievable only through a multiphase and...journal article 2022

Martinelli, Cristiano (author), Coraddu, A. (author), Cammarano, Andrea (author)Most of the optimisation studies of Vibration Energy Harvesters (VEHs) account for a single output quantity, e.g. frequency bandwidth or maximum power output, but this approach does not necessarily maximise the system efficiency. In those applications where VEHs are suitable sources of energy, to achieve optimal design it is important to...journal article 2022

Arano Barenys, Assis (author), Colombo, Matteo (author), Martinelli, Paolo (author), Øverli, Jan Arve (author), Hendriks, M.A.N. (author), Kanstad, Terje (author), di Prisco, Marco (author)This study investigated the effect of fire on the ultimate load-bearing capacity of reinforced concrete (RC) slabs. The structural response of RC circular specimens subjected to static load conditions after exposure to a hydrocarbon fire on one side of the specimen was examined. Two fire exposure times were considered (60 and 120 min) in...journal article 2022

Martinelli, M. (author), Pisano, F. (author)Cone penetration tests (CPTs) can quantitatively inform about the mechanical state of a sand. However, relating measured cone resistance values to sand state requires complex back-analysis of the processes occurring in the soil during the test. This paper provides new evidence of the value added in this area by modern large-deformation...journal article 2022

Martinelli, M. (author), Galavi, Vahid (author)This paper describes an MPM formulation using linear quadrilateral elements suitable for soil-structure-interaction problems. The volumetric locking and stress-oscillations are mitigated using a reduced integration technique and the Gauss integration scheme, respectively. The formulation can be used with both structured and unstructured...journal article 2022

Li, Meng (author), Chen, Yifei (author), Lal, C. (author), Conti, M. (author), Martinelli, Fabio (author), Alazab, Mamoun (author)Security and privacy issues have become a major hindrance to the broad adoption of Ride-Hailing Services (RHSs). In this article, we introduce a new collusion attack initiated by the Ride-Hailing Service Provider (RHSP) and a driver that could easily link the real riders and their anonymous requests (credentials). Besides this attack,...journal article 2022

Martinelli, J. (author), Tei, Lorenzo (author), Geninatti Crich, Simonetta (author), Alberti, Diego (author), Djanashvili, K. (author)It is known that phenylboronic acid (PBA) can target tumor tissues by binding to sialic acid, a substrate overexpressed by cancer cells. This capability has previously been explored in the design of targeting diagnostic probes such as Gd- and 68Ga-DOTA-EN-PBA, two contrast agents for magnetic resonance imaging (MRI) and positron emission...journal article 2021
