Round Robin Testing initiative for fiber reinforced polymer (FRP) reinforcement
2011
An international Round Robin Testing (RRT) programm e on FRP reinforcement was conducted within the framework of the Marie Curie R esearch Training Network, EN- CORE, and with the support of Task Group 9.3 of the International Federation for Structural Concrete (fib). Eleven laboratories and six manufacturers and suppliers participated in this exercise. As part of this exte nsive experimental endeavour, one or more of the following tests were performed by the partic ipating laboratories: 1) tensile tests on FRP bars and strips; 2) tensile tests on FRP lamina tes; 3) double bond shear tests on FRP laminates (Externally Bonded Reinforcement, EBR) an d FRP bars/strip (Near Surface Mounted rein…

The Reinforcement Effect of Strain Gauges Embedded in Low Modulus Material
2013
The reinforcement effect of electrical resistance strain gauges is well-described in the literature, especially for strain gauges installed on surface. This paper considers the local reinforcement effect of strain gauges embedded within low Young modulus materials. In particular, by using a simple theoretical model, already used for strain gauges installed on the surface, it proposes a simple formula that allows the user to evaluate the local reinforcement effect of a generic strain gauge embedded on plastics, polymer composites, etc. The theoretical analysis has been integrated by numerical and experimental analyses, which confirmed the reliability of the proposed model.
Roboception and adaptation in a cognitive robot
2023
In robotics, perception is usually oriented at understanding what is happening in the external world, while few works pay attention to what is occurring in the robot’s body. In this work, we propose an artificial somatosensory system, embedded in a cognitive architecture, that enables a robot to perceive the sensations from its embodiment while executing a task. We called these perceptions roboceptions, and they let the robot act according to its own physical needs in addition to the task demands. Physical information is processed by the robot to behave in a balanced way, determining the most appropriate trade-off between the achievement of the task and its well being. The experiments show …
A Reinforcement Learning Approach for User Preference-aware Energy Sharing Systems
2021
Energy Sharing Systems (ESS) are envisioned to be the future of power systems. In these systems, consumers equipped with renewable energy generation capabilities are able to participate in an energy market to sell their energy. This paper proposes an ESS that, differently from previous works, takes into account the consumers’ preference, engagement, and bounded rationality. The problem of maximizing the energy exchange while considering such user modeling is formulated and shown to be NP-Hard. To learn the user behavior, two heuristics are proposed: 1) a Reinforcement Learning-based algorithm, which provides a bounded regret and 2) a more computationally efficient heuristic, named BPT- ${K}…
TERMODINAMICA, CAMPI QUANTICI E FUNZIONI MENTALI
2010
Nel tentativo di fornire spiegazioni esaurienti sul fenomeno della mente umana, il presente saggio scientifico di anatomia comparata e di fisiologia considera alcune tesi di fondo che si collegano a nuovi parametri fisici della realtà che ci circonda.
Il destino delle cupole, tra crolli, demolizioni, consolidamenti e ricostruzioni_The destiny of domes, through collapses, demolitions, reinforcements…
2017
Le cupole sono sempre state opere di grande impegno costruttivo e di sperimentazione statica. L’ardita realizzazione o il semplice mancato crollo delle stesse rendeva celebre il progettista e la fabbrica in cui la cupola veniva inserita (spesso anche in un secondo momento, rispetto al primigenio nucleo), allo stesso modo i frequenti collassi ed i dissesti ne segnavano gli insuccessi e le qualità, sia nelle ricostruzioni che nei consolidamenti. Se il sisma costituiva il pericolo maggiore, non minore era il rischio correlato alla costruzione malfatta, prassi costante in aree marginali, che veniva spesso mascherata da finiture di alta qualità. I frequenti disastri fin dall’epoca post-rinascime…
Quantum Machine Learning: A tutorial
2021
This tutorial provides an overview of Quantum Machine Learning (QML), a relatively novel discipline that brings together concepts from Machine Learning (ML), Quantum Computing (QC) and Quantum Information (QI). The great development experienced by QC, partly due to the involvement of giant technological companies as well as the popularity and success of ML have been responsible of making QML one of the main streams for researchers working on fuzzy borders between Physics, Mathematics and Computer Science. A possible, although arguably coarse, classification of QML methods may be based on those approaches that make use of ML in a quantum experimentation environment and those others that take…
Novel method for functionalising and patterning textile composites:Liquid resin print
2016
Abstract The paper reports a novel method of integrating resin into continuous textile reinforcement. The method presents a print of liquid reactive resin into textile preforms. A series of targeted injections forms a patch which upon consolidation and curing transforms into a stiff region continuously spanning through preform thickness. Enhancing the injected resin with conductive phase allows creating a pattern of patches with controlled dimensions and added functionalities. Patterned composites reveal features which are not typical for conventional composites such as fibre bridged interfaces, regular thickness variation, and gradient matrix properties. The presented study explores the ro…
Experimental Studies Regarding Mechanical Behaviour of Textile Reinforcements Laminated Composite Materials
2013
The aim of this paper is to determine the mechanical properties of textile reinforcements laminated composite material and to establish the influence of thickness about these properties. The composite material used for this is a laminated sheet of HGW 2082. In order to study the mechanical behaviour of these kinds of materials we select two experimental tests: uniaxial test and bending test. For the uniaxial test we have measured the maximum load, the maximum extension, the maximum tensile stress and the maximum tensile strain. Also, using an optical extensometer we measured the major and the minor strains. For the bending test we measured the maximum load and the maximum bending deflection…
