description: The present paper introduces an original biofeedback system for improving human balance control, whose underlying principle consists in providing additional sensory information related to foot sole pressure distribution to the user through a tongue-placed tactile output device. To assess the effect of this biofeedback system on postural control during quiet standing, ten young healthy adults were asked to stand as immobile as possible with their eyes closed in two conditions of No-biofeedback and Biofeedback. Centre of foot pressure (CoP) displacements were recorded using a force platform. Results showed reduced CoP displacements in the Biofeedback relative to the No-biofeedback condition. The present findings evidenced the ability of the central nervous system to efficiently integrate an artificial plantar-based, tongue-placed tactile biofeedback for controlling control posture during quiet standing.

description: La tesi ha per oggetto lo studio dei segni presenti nel PHerc. 1497 (Filodemo, De musica, libro IV). A tal fine è stata effettuata l’analisi comparata di tutti i testimoni del papiro: l’originale; i disegni oxoniensi e napoletani (effettuati tra la fine del XVIII e gli inizi del XIX sec.); le tavole incise e stampate nel I vol. della Collectio Prior (Napoli 1793); le edizioni del Kemke (Lipsia 1884) e della Neubecker (Napoli 1986); le fotografie digitali. In fase preliminare è stata considerata la vasta bibliografia sia sull’uso e sullo studio dei segni nel libro antico e nei papiri ercolanesi sia sui problemi bibliologico-ricostruttivi e sul contenuto dell’esemplare in questione. Il controllo autoptico del papiro ha consentito di rilevare per la prima volta numerosi segni prima d’ora mai individuati (paragraphoi, diplai, riempitivi e coronidi), sulla funzione dei quali ci si è interrogati mediante l’analisi di alcuni brani particolarmente significativi. Infine, sono stati indagati i sistemi adottati dallo scriba per espungere e correggere e sono stati altresì esposti i termini della discussione avviata dagli studiosi (Cavallo, Delattre, Capasso e Puglia) sull’interpretazione della duplice subscriptio e della nota bibliologica finale del papiro. Il lavoro si è concretizzato nella costituzione di una tabella sinottica in cui sono stati registrati linea per linea i segni e le particolarità grafiche del volumen analizzato. Tale ricerca s’inserisce nell’ambito di un progetto di più ampio respiro, avviato qualche anno fa dal Centro Internazionale per lo Studio dei Papiri Ercolanesi, che mira ad uno studio quanto più è possibile sistematico sui segni nei rotoli ercolanesi. L’intento di tale progetto è migliorare la conoscenza della storia del libro antico e fornire agli editori dei testi un utile strumento di studio.

description: New neutral heavy gauge bosons ($Z^\prime$) are predicted within many extensions of the Standard Model. While in case they couple to quarks the LHC bounds are very stringent, leptophilic $Z^\prime$ bosons (even with sizable couplings) can be much lighter and therefore lead to interesting quantum effects in precision observables (like $(g-2)_μ$) and generate flavour violating decays of charged leptons. In particular, $\ell\to\ell^\primeν\barν$ decays, anomalous magnetic moments of charged leptons, $\ell\to\ell^\primeγ$ and $\ell\to3\ell^\prime$ decays place stringent limits on leptophilic $Z^\prime$ bosons. Furthermore, in case of mixing $Z^\prime$ with the SM $Z$, $Z$ pole observables are affected. In light of these many observables we perform a global fit to leptophilic $Z^\prime$ models with the main goal of finding the bounds for the $Z^\prime$ couplings to leptons. To this end we consider a number of scenarios for these couplings. While in generic scenarios correlations are weak, this changes once additional constraints on the couplings are imposed. In particular, if one considers an $L_μ-L_τ$ symmetry broken only by left-handed rotations, or considers the case of $τ-μ$ couplings only. In the latter setup, on can explain the $(g-2)_μ$ anomaly and the hint for lepton flavour universality violation in $τ\toμν\barν/τ\to eν\barν$ without violating bounds from electroweak precision observables.

description: The phase-space structure of two families of galactic potentials is approximated with a resonant detuned normal form. The normal form series is obtained by a Lie transform of the series expansion around the minimum of the original Hamiltonian. Attention is focused on the quantitative predictive ability of the normal form. We find analytical expressions for bifurcations of periodic orbits and compare them with other analytical approaches and with numerical results. The predictions are quite reliable even outside the convergence radius of the perturbation and we analyze this result using resummation techniques of asymptotic series.

description: Determining the level of chemical complexity within dense starless and gravitationally bound prestellar cores is crucial for constructing chemical models, which subsequently constrain the initial chemical conditions of star formation. We have searched for complex organic molecules (COMs) in the young starless core L1521E, and report the first clear detection of dimethyl ether (CH$_3$OCH$_3$), methyl formate (HCOOCH$_3$), and vinyl cyanide (CH$_2$CHCN). Eight transitions of acetaldehyde (CH$_3$CHO) were also detected, five of which (A states) were used to determine an excitation temperature to then calculate column densities for the other oxygen-bearing COMs. If source size was not taken into account (i.e., if filling fraction was assumed to be one), column density was underestimated, and thus we stress the need for higher resolution mapping data. We calculated L1521E COM abundances and compared them to other stages of low-mass star formation, also finding similarities to other starless/prestellar cores, suggesting related chemical evolution. The scenario that assumes formation of COMs in gas-phase reactions between precursors formed on grains and then ejected to the cold gas via reactive desorption was tested and was unable to reproduce observed COM abundances, with the exception of CH$_3$CHO. These results suggest that COMs observed in cold gas are formed not by gas-phase reactions alone, but also through surface reactions on interstellar grains. Our observations present a new, unique challenge for existing theoretical astrochemical models.

description: We develop a theoretical framework that allows us to compare electromagnetism and gravitation in a fully covariant way. This new scenario does not rely on any kind of approximation nor associate objects with different operational meaning as it's sometime done in the literature. We construct the electromagnetic analogue to the Riemann and Weyl tensors and develop the equations of motion for these objects. In particular, we are able to identify precisely how and in what conditions gravity can be mapped to electrodynamics. As a consequence, many of the gemometrical tools of General Relativity can be applied to Electromagnetism and vice-versa. We hope our results would shed new light in the nature of electromagnetic and gravitational theories.

The next generation: Impact of high-order analytical information on effective one body waveform models for noncircularized, spin-aligned black hole binaries

description: We explore the performance of an updated effective-one-body (EOB) model for spin-aligned coalescing black hole binaries designed to deal with any orbital configuration. The model stems from previous work involving the \TEOBResumS{} waveform model, but incorporates recently computed analytical information up to fifth post-Newtonian (PN) order in the EOB potentials. The dynamics is then informed by Numerical Relativity (NR) quasi-circular simulations (incorporating also recently computed 4PN spin-spin and, optionally, 4.5PN spin-orbit terms). The so-constructed model(s) are then compared to various kind of NR simulations, covering either quasi-circular inspirals, eccentric inspirals and scattering configurations. For quasi-circular (534 datasets) and eccentric (28 datasets) inspirals up to coalescence, the EOB/NR unfaithfulness is well below $1\%$ except for a few outliers in the high, positive, spin corner of the parameter space, where however it does not exceed the $3\%$ level. The EOB values of the scattering angle are found to agree ($\lesssim 1\%$) with the NR predictions for most configurations, with the largest disagreement of only $\sim 4\%$ for the most relativistic one. The inclusion of some high-order analytical information in the orbital sector is useful to improve the EOB/NR agreement with respect to previous work, although the use of NR-informed functions is still crucial to accurately describe the strong-field dynamics and waveform.

description: We investigate the influence of polymer-pore interactions on the translocation dynamics using Langevin dynamics simulations. An attractive interaction can greatly improve translocation probability. At the same time, it also increases translocation time slowly for weak attraction while exponential dependence is observed for strong attraction. For fixed driving force and chain length the histogram of translocation time has a transition from Gaussian distribution to long-tailed distribution with increasing attraction. Under a weak driving force and a strong attractive force, both the translocation time and the residence time in the pore show a non-monotonic behavior as a function of the chain length. Our simulations results are in good agreement with recent experimental data.

description: Many black holes (BHs) detected by the Laser Interferometer Gravitational-wave Observatory (LIGO) and the Virgo detectors are multiple times more massive than those in X-ray binaries. One possibility is that some BBHs merge within a few Schwarzschild radii of a supermassive black hole (SMBH), such that the gravitational waves (GWs) are highly redshifted, causing the mass inferred from GW signals to appear higher than the real mass. The difficulty of this scenario lies in the delivery of BBH to such a small distance to a SMBH. Here we revisit the theoretical models for the migration of compact objects (COs) in the accretion discs of active galactic nuclei (AGNs). We find that when the accretion rate is high so that the disc is best described by the slim disc model, the COs in the disc could migrate to a radius close to the innermost stable circular orbit (ISCO) and be trapped there for the remaining lifetime of the AGN. The exact trapping radius coincides with the transition region between the sub- and super-Keplerian rotation of the slim disc. We call this region "the last migration trap" because inside it COs can no longer be trapped for a long time. We pinpoint the parameter space which could induce such a trap and we estimate that the last migration trap contributes a few per cent of the LIGO/Virgo events. Our result implies that a couple of BBHs discovered by LIGO/Virgo could have smaller intrinsic masses.

description: Using high quality undoped GaAs/AlGaAs heterostructures with optically patterned insulation between two layers of gates, it is possible to investigate very low density mesoscopic regions where the number of impurities is well quantified. Signature appearances of the scattering length scale arise in confined two dimensional regions, where the zero-bias anomaly (ZBA) is also observed. These results explicitly outline the molecular beam epitaxy growth parameters necessary to obtain ultra low density large two dimensional regions as well as clean reproducible mesoscopic devices.

description: Abstract

Field based phenotypic performance along with mean biometrical variables of heritability and genetic advance guide the plant breeders to select superior genotypes. In the changing climate scenario, this is the most pivotal and challenging tasks for plant breeder to select the best plants based on desirable morphological and physiological attributes to advance to final stages of varietal development. The newly developed wheat varieties that exhibit not only early maturity but possess high potential yield and resistance/tolerance to biotic and abiotic stresses can positively contribute to food insecurity issues. To achieve this task, a set of 50 genotypes were received from CIMMYT-Mexico as Semi-arid wheat yield trial (SAWYT) and were sown at the research fields of Cereal Crops Research Institute (CCRI), Pirsabak Nowshera (74OE and 32ON), during the Rabi season of 2017-18. High Significant differences were observed in days to heading (DH), days to maturity (DM), plant height (PH) (cm) and grain yield (GY) (kg ha-1). DH, DM, PH, and GY ranged from 110.02 to 118.52, 156 to 163, 85.56 cm to 110.56 cm and 1123 kg ha-1 to 4513 kg ha-1, respectively.  Genetic variation components i.e., h2 (B.S), GCV, PCV and G.A were estimated for yield and other morphological traits. The results showed the existence of adequate genetic variability among the tested wheat genotypes. Moderate to high heritability estimates were computed for DH (0.73), DM (0.36), PH (0.49), and GY (0.37). High GCV were found in GY and PH, moderate in days to heading while low in days to maturity. Similarly, high PCV was recorded for GY and PH while moderate for DH and DM.  Genetic advance, representing the potential gain through selection, was computed for GY (14.72%), PH (5.25%), DH (2.33%), and DM (0.64%), with varying levels of genetic improvement. High genetic advance with moderate heritability was recorded for GY while low genetic advance with high and moderate heritability was recorded for DH, PH and DM. The results suggested the presence of non-additive gene action, including dominance and epistasis, indicating that delayed selection may lead to more fruitful outcomes. Based on present findings the superior genotypes were SAWYT-V12, V14, V15, V17, V18, V24, V29, V37, V44, V46 and V49, which need to be further investigated for concrete results. This study emphasizes the importance of field-based evaluations and biometrical computations in selecting superior wheat genotypes, which will contribute to the development of climate resilient, high-yielding and disease resistant wheat varieties that can address the challenges of food security in changing climatic conditions.
Stochastic quantization of boson and fermion fields
Creators: name: Hayward, Geoffrey
Publisher: name: University of British Columbia
Year: 2010

description: We consider two strategies for stochastic quantization. With the first, one posits an additional time dimension (fictitious time) and describes the evolution of classical fields by means of the Langevin equation. One then evaluates stochastic averages of the field functions. In the limit that the fictitious time goes to infinity, these approach the time ordered correlation functions of canonically quantized field theory. We conclude that, while this strategy successfully describes QED and other quantum field theories, it is contrived and probably lacks deep physical significance. With the second strategy for field quantization, one begins with a classical action in either one or two extra dimensions coupled to an external random source. We review a method of quantizing bosonic fields which uses this strategy. Furthermore, we present an analogous method for quantizing fermion fields and a possible new way of quantizing interacting fermion and boson fields. Finally, we discuss applications to quantum mechanics and stochastically quantize the simple harmonic oscillator.

description: We study the transport through evanescent waves in graphene quantum dots of different geometries. The transmission is suppressed when the leads are attached to edges of the same majority sublattice. Otherwise, the transmission depends exponentially on the distance between leads in rectangular dots, and as a power law in circular dots. The transmission through junctions where the transmitted and reflected currents belong to the opposite valley as the incoming one depends on details of the lattice structure at distances comparable to the atomic spacing.
Continuum random-phase approximation for gamma transition between excited states in neutron-rich nuclei

Year: 2021

description: A characteristic feature of collective and particle-hole excitations in neutron-rich nuclei is that many of them couple to unbound neutron in continuum single-particle orbits. The continuum random phase approximation (cRPA) is a powerful many-body method that describes such excitations, and it provides a scheme to evaluate transition strengths from the ground state. In an attempt to apply cRPA to the radiative neutron capture reaction, we formulate in the present study an extended scheme of cRPA that describes gamma-transitions from the excited states under consideration, which decay to low-lying excited states as well as the ground state. This is achieved by introducing a non-local one-body operator which causes transitions to a low-lying excited state, and describing a density-matrix response against this operator. As a demonstration of this new scheme, we perform numerical calculation for dipole, quadrupole, and octupole excitations in $^{140}$Sn, and discuss E1 and E2 transitions decaying to low-lying $2^{+}_{1,2}$ and $3^{-}_{1}$ states. The results point to cases where the branching ratio to the low-lying states is larger than or comparable with that to the ground state. We discuss key roles of collectivity and continuum orbits in both initial and final states.

description: This paper introduces a continuous model for Multi-cellular Developmental Design. The cells are fixed on a 2D grid and exchange "chemicals" with their neighbors during the growth process. The quantity of chemicals that a cell produces, as well as the differentiation value of the cell in the phenotype, are controlled by a Neural Network (the genotype) that takes as inputs the chemicals produced by the neighboring cells at the previous time step. In the proposed model, the number of iterations of the growth process is not pre-determined, but emerges during evolution: only organisms for which the growth process stabilizes give a phenotype (the stable state), others are declared nonviable. The optimization of the controller is done using the NEAT algorithm, that optimizes both the topology and the weights of the Neural Networks. Though each cell only receives local information from its neighbors, the experimental results of the proposed approach on the 'flags' problems (the phenotype must match a given 2D pattern) are almost as good as those of a direct regression approach using the same model with global information. Moreover, the resulting multi-cellular organisms exhibit almost perfect self-healing characteristics.

description: Despite sophisticated phishing email detection systems, and training and awareness programs, humans continue to be tricked by phishing emails. In an attempt to better understand why phishing email attacks still work and how best to mitigate them, we have carried out an empirical study to investigate people's thought processes when reading their emails. We used a scenario-based role-play "think aloud" method and follow-up interviews to collect data from 19 participants. The experiment was conducted using a simulated web email client, and real phishing and legitimate emails adapted to the given scenario. The analysis of the collected data has enabled us to identify eleven factors that influence people's response decisions to both phishing and legitimate emails. Furthermore, based on the user study findings, we discuss novel insights into flaws in the general email decision-making behaviors that could make people susceptible to phishing attacks.

Nuovo approccio teorico proposto per i profili di velocità
Creators: name: Marini, Gustavo
Publisher: name: Università degli Studi di Napoli Federico II

description: A new theoretical approach based on principle of maximum Shannon entropy is proposed to estimate the variability of a function defined in two-dimensional space. This approach is applicable to whatever variable defined in a two dimensional domain when you need understand how that varies. By means of this approach an analytical model for two-dimensional velocity distribution, in open channel flow, is developed. The model-derived velocity data are compared with experimental data derived by laboratory tests, on purpose carried out, and by river measures. This comparison shows that the accuracy of the method is bigger or comparable to that obtained by using other literature methods and needs less information to be applied. Nella tesi viene proposto un nuovo approccio teorico basato sul principio della massima entropia definita da Shannon per la valutazione della variabilità di una generica funzione, definita in un dominio bidimensionale. Sulla base di tale approccio è stato poi messo a punto un modello teorico per la stima della distribuzione di velocità in una corrente a pelo libero. I valori ottenuti dal modello sono stati successivamente confrontati con misure sperimentali ricavate sia nell’ambito di un’estesa indagine di laboratorio all’uopo attivata, sia a partire da misure in sito su corsi d’acqua naturali. Il confronto mostra che il metodo proposto fornisce risultati generalmente più accurati (o comunque analoghi) rispetto a quelli forniti dai modelli di letteratura, pur richiedendo una minore quantità di informazioni per essere applicato.

description: We construct here the parametric representation of a translation-invariant renormalizable scalar model on the noncommutative Moyal space of even dimension $D$. This representation of the Feynman amplitudes is based on some integral form of the noncommutative propagator. All types of graphs (planar and non-planar) are analyzed. The rôle played by noncommutativity is explicitly shown. This parametric representation established allows to calculate the power counting of the model. Furthermore, the space dimension $D$ is just a parameter in the formulas obtained. This paves the road for the dimensional regularization of this noncommutative model.

 Fenchel (1965) described new ciliate genus Askoella Fenchel, 1965 with the type species A. janssonі Fenchel, 1965 (Fig. 2 A–C) from the amphipod crustacean Gammarus oceanicus Segerstråle, 1947 (type host). This ciliate was found on 50% of Gammarus individuals collected near Asko (Denmark, type locality). In addition A. janssonі has been observed on a specimen of G. locusta (Linnaeus, 1758) from the Oresund strait.
 The cell body of A. janssoni is ovoid and flattened. The left rim is more convex than the right one. The ventral side is slightly concave while the dorsal side is convex. There are two kineties on the dorsal side of the body and three kineties on the ventral side. The cytostome is provided by a vestibulum and situated on the anterior third of the ventral body side, to the right of the middle. The macronucleus is large and U-shaped. There is a contractile vacuole situated in the posterior end of body.
 Jankowski (1967b) described a second species of the genus, A. heliostoma Jankowski, 1967 (Fig. 2 D) from acorn barnacle Semibalanus balanoides (Linnaeus, 1767) collected in the Barents Sea near Murmansk, Russia (type locality).
 Askoella heliostoma has an oval, small, light coloured body filled with food vacuoles. The apical region of the cell body is tapered, whereas the antapical is provided by a characteristic groove which leads to a long convoluted canal terminating near rosette. The rosette septa are not arranged parallely one to another like in A. janssoni, but there are radially arranged as in the rosette trophonts of Gymnodinioides. Jankowski (1967b) considered this distinctive character to distinguish A. heliostoma from A. janssoni, and Jankowski (1967b, 1972) included some observations of A. helіostoma nutritions and reproductions.

description: This paper describes an efficient method for extracting quantitative data from time sequences of fluid flow images. It also introduces a computer automated method for the identification of coherent structures in turbulent flow fields. This method eliminates subjective manual judgement in the crucial stage of coherent structure recognition. The surface motion on turbulent grid flow (Reynolds number 10") was visualized by recording images of tracer particles on a video tape. Each video frame was then digitized as a binary image using a microcomputer. By tracking and connecting the tracer paths through successive frames using a mainframe computer the flow history was reconstructed. Streak trajectories were then fitted by polynomials to give various flow parameters of interest over desired flow times. In particular the linear and angular velocities were determined as scatter points from which mesh fields were interpolated. Coherent structures were identified by thresholding the field of angular velocity. Using the interpolated mesh fields of linear velocities, each coherent structure was parametrized with the properties of size, average linear and angular velocities, and energy content. The flow dynamics and interactions are then discussed using these structure properties. The system was developed primarily to enhance data recognition for a new model of turbulence based on the energetics of coherent structures. It is also intended as a general technique to be used for other flow visualization and coherent structure studies. Applying the system to the initial stage of grid turbulence, it successfully recognized over 80% of all the coherent structures manually identified. Parameter results using these automatically identified structures were compared with established results and model predictions. Limitation and possible improvement on the present two dimensional system is discussed. Various aspects in extending the system to a three dimensional environment are also presented.

description: The large-scale analysis of scholarly artifact usage is constrained primarily by current practices in usage data archiving, privacy issues concerned with the dissemination of usage data, and the lack of a practical ontology for modeling the usage domain. As a remedy to the third constraint, this article presents a scholarly ontology that was engineered to represent those classes for which large-scale bibliographic and usage data exists, supports usage research, and whose instantiation is scalable to the order of 50 million articles along with their associated artifacts (e.g. authors and journals) and an accompanying 1 billion usage events. The real world instantiation of the presented abstract ontology is a semantic network model of the scholarly community which lends the scholarly process to statistical analysis and computational support. We present the ontology, discuss its instantiation, and provide some example inference rules for calculating various scholarly artifact metrics.

description: Pattern recognition methods offer technological background for a variety of applications in a modern information society. They are however undermined by several kinds of "adversarial" misuses like email and web spam, attacks to computer networks, etc. A classical example of such "adversarial" environment are various evasion techniques used in generation of spam emails. Similar problems arise in web search (web spam) and malware analysis (obfuscation and polymorphism). The underlying problem is that pattern recognition, as well as data analysis techniques in general, have not been designed to work in adversarial environments. This consideration arise with the problem to define a general framework to prevents this kind of evasions. In this thesis we propose some techniques to approach with the "adversarial" environments. We first present a novel multiple classifier systems approach, called SOCIAL, and then we will show some methodologies applied to different applications such as the spam detection and the traffic identification.

description: We determine the mass and strength of the scalar meson from NN scattering data by renormalizing the One Boson Exchange Potential. This procedure provides a great insensitivity to the unknown short distance interaction making the vector mesons marginally important and allowing for SU(3) couplings in the 1S0 channel. The scalar meson parameters are tightly constrained by low energy np. We discuss whether this scalar should be compared to the recent findings based on the Roy equations analysis of pipi scattering.

description: Negli ultimi anni, un numero sempre maggiore di aziende zootecniche ha iniziato ad avvalersi delle biotecnologie riproduttive, perché così facendo possono incrementare le performance produttive e indirizzare la produzione verso una qualità spesso impensabile, ottenendo nel contempo la riduzione dei rischi di trasmissione di malattie, tutto nell’ottica di una risposta più adeguata alle richieste di un mercato sempre più specifico. Pertanto prove sperimentali differenti sono state condotte al fine di migliorare, l’efficienza della fecondazione in vitro e la resa nella coltura embrionale in vitro nelle specie bovina ed in quella bufalina  L’insieme dei risultati ha dimostrato l’esistenza di evidenti differenze nei fabbisogni metabolici degli embrioni bufalini rispetto a quelli bovini, di cui bisogna tener conto per ottimizzare il sistema in questa specie.

description: Background:Gingival recessions (GR) and the lack of keratinized tissue with thin phenotype hinder proper oral hygiene. Various surgical tunneling techniques have been proposed to treat anterior mandibular GR However, the coronally advanced tunnel technique remains challenging for RT2 and RT3 recession type defects. This case series aims to present a novel technique to cover multiple adjacent recessions and modify the patient's phenotype based on the VISTA technique.
Methods:A total of 6 patients presenting 30 anterior mandibular recession type defects RT2 and RT3 with thin phenotypes, were included in this study. The Split Modified VISTA technique involved the following steps: initial intrasulcular incisions, full thickness tunnel, vertical access incision, partial tunneling and a horizontal connecting incision below the tunnel. A Connective tissue graft harvested from the palate and sutured, finally the vertical incision is closed. Outcomes, including root coverage and phenotype changes, were assessed at six months postoperatively.
Results:Seventeen RT2 sites achieved complete root coverage (94.4%), and ten RT3 sites achieved complete root coverage (83.3%). Overall, 90% of sites achieved complete root coverage, and 100% of patients experienced phenotype modification from thin to thick.
Conclusion:The Split Modified VISTA technique represents an innovative surgical approach for achieving complete root coverage in anterior mandible. With the use of this technique, good results were achieved, reaching a 90% of complete root coverage, with higher rates of complete root coverage in the RT2 than in the RT

description: Le industrie del settore aeronautico sono alla continua ricerca di nuove tecniche costruttive e di nuovi materiali, che conferiscano alle strutture dei velivoli una resistenza meccanica ed alla corrosione superiore, simultaneamente si richiede che queste strutture siano sempre più leggere. Sono quindi state realizzate nuove leghe di Alluminio che rispondono a questi requisiti, allo stesso tempo è stata verificata la possibilità di utilizzare su questi materiali, una nuova tecnica di saldatura: la Friction Stir Welding (FSW).
Sono stati realizzati dei giunti FSW su leghe di alluminio AA6056 T4, AA2024 T3, AA2139 T3 e AA 2198 T3, con il supporto della analisi statistica attraverso il Design of Experiment (DoE), ovvero realizzando una pianificazione ragionata dei giunti da realizzare e dei test da eseguire.
I test condotti su tali giunti, hanno evidenziato le potenzialità di questa tecnica di saldatura, in quanto consente di recuperare fino al 100% le caratteristiche meccaniche dei materiali di base. Al contrario, le tecniche classiche di saldatura come le Metal Inert Gas (MIG), Tungsten Inerty Gas (TIG), Laser Beam Welding (LBW), consentono di realizzare giunti con proprietà meccaniche che non superano il 70% di quelle dei materiali di partenza.
Le tecniche di pianificazione degli esperimenti DoE, inoltre, permettono di realizzare dei modelli numerici per descrivere le proprietà caratteristiche dei giunti al variare dei parametri caratteristici del processo di saldatura.
Ognuna delle leghe in esame, ha manifestato un comportamento differente dall’altra dal punto di vista delle proprietà meccaniche. Per realizzare i giunti, è necessario adoperare dei parametri di processo completamente differenti per ciascuna lega. Dall’analisi dei dati sperimentali, quindi, risulta che la massima resa in termini di tensione massima e tensione di snervamento si realizza per una combinazione dei parametri di processo che non coincidono.
Infine è stata realizzata una campagna di prove per verificare la suscettibilità allo Stress Corrosion Cracking (SCC) di tali giunti. Tale test è necessario, in quanto le strutture di interesse aeronautico sono soggette all’azione simultanea di sollecitazione meccanica ed esposizione ad ambienti corrosivi, è quindi opportuno valutare l’effetto simultaneo di tali fenomeni sui giunti realizzati. Il comportamento alla corrosione che emerge dai test, evidenzia dei comportamenti completamente differenti fra le leghe esaminate.
