Modal dynamic identification of civil structures via inverse analysis based on Heterogeneous Data Fusion and post-processing
Creators: name: RAVIZZA, Gabriele
Publisher: name: Universit� degli studi di Bergamo
Year: 2021

description: The present Doctoral Thesis belongs to the Scientific-Disciplinary Sector of Mechanics of Solids and Structures (ICAR/08 - Scienza delle Costruzioni), and falls within the broader research field of Structural Health Monitoring (SHM), with specific reference to the civil engineering context. Nowadays, SHM-based approaches and the attached development of consistent numerical modeling, with related model updating, may constitute fundamental tools to pursue the goal of engineering structural safety, preventing possible causes of damage that may even lead to structural failure. In particular, this research work proposes complementary post-processing approaches to address the issue of noise cleaning on dynamic structural response signals typically encountered in structural engineering applications (specifically, acceleration and displacement signals). Two approaches are mainly presented, especially aiming at enhancing displacements response signals, since they are commonly affected by higher levels of noise, also due to the low-cost monitoring instrumentation that may possibly be employed. Heterogeneous Data Fusion (HDF) procedures, which involve a Kalman Filter (KF)-based implementation, are primarily investigated, by integrating data acquired from different types of sensors, so that the resulting information turns out to be characterized by a lower degree of uncertainty. A denoising approach is also inspected, as the process through which a source signal may be reconstructed, starting from a recorded, noise-affected one, by removing its noisy part, without losing the useful information incorporated within it. A HDF procedure and a denoising approach are then combined within an integrated strategy, in an effort to enhance the reliability of the monitoring process, for assessing the health conditions of bridges. Aspiring at providing a comprehensive research framework on these topics, both synthetic response signals and real response signals are considered, as well as signals displaying a different nature (non-stationary vs. stationary). These processed response signals are finally employed toward modal identification purposes, for extracting the modal properties of the monitored structure.

description: We construct a geometric model of eight-dimensional manifolds and realize them in the context of type II string theory. These eight-manifolds are constructed by non-trivial $T^{4}$ fibrations over Calabi-Yau two-folds. These give rise to eight-dimensional non-Kahler Hermitian manifolds with $SU(4)$ structure. The eight-manifold is also a circle fibration over a seven-dimensional $G_{2}$ manifold with skew torsion. The eight-manifolds of this type appear as internal manifolds with $SU(4)$ structure in type IIB string theory with $F_{3}$ and $F_{7}$ fluxes. These manifolds have generalized calibrated cycles in the presence of fluxes.

The Two-Echelon Location Routing Problems: State of the Art, Models and Algorithms

Year: 2014

description: The Two-Echelon Routing Problem constitutes a class of combinatorial optimization problems with applications in many different fields such as city logistic planning, intermodal transportation, postal and parcel delivery distribution systems and so on. This thesis contains: - a survey of the main contributions related to the two-echelon routing, focusing on the Two-Echelon Location Routing Problem, on the Two-Echelon Vehicle Problem and on the Truck and Trailer Routing Problem; - an analysis of a particular version of the Two-Echelon Location Routing Problem with single source, referred as Single Vehicle Two-Echelon Location Routing Problem, with two mathematical formulations and a heuristic algorithm; - some computational experiments aiming at test the effectiveness of the formulations and the heuristic algorithm. The thesis is divided in three parts: - a literature review of the Two-Echelon Location Routing Problem, of the Two-Echelon Vehicle Routing Problem and of the Truck and Trailer Routing Problem. The Two-Echelon Location Routing Problem refers to a class of problem directly derived from the well-known Location Routing Problem in which two sets of facilities must be located and two levels of routing have to be considered. The Two-Echelon Vehicle Routing Problem is derived from the Vehicle Routing Problem. In this class of problems the distribution of freight is managed through a set of satellites, where operation of consolidation, and/or transhipment and/or storage are performed. The Truck and Trailer Routing Problem models a distribution system in which a vehicle fleet, composed by truck units and trailer units, is used to serve the demand of a set of customers, some of which are accessible only by a truck without trailer; - the description of the Single Vehicle Two-Echelon Location Routing Problem with emphasis on its structure and its components, plus the introduction of two integer programming formulations to determine the optimal location and the optimal number of a set of capacitated facilities, the assignment of customers to these facilities and the related routes. Four sets of instances are adapted from the literature and the results of proposed formulation are reported, comparing their performances in terms of solution quality and computation times. - the introduction of a heuristic algorithm to solve the problem. Five variants of the algorithm are developed, differing from each other for the assignment procedures of the customers to the satellites. The results provided by such algorithm are compared with the optimal solutions, or in some cases with the best lower bounds provided by CPLEX solving the two integer models.

description: We present the results of initial spectrographic followup with the Very Large Telescope (UT3, Melipal) for $K_s \ge 14$ Galactic plane CIV emission-line candidates in the near-infrared (NIR). These 7 faint stars all display prominent HeI and CIV emission lines characteristic of a carbon-rich Wolf-Rayet star. They have NIR colours which are much too blue to be those of distant, classical WR stars. The magnitudes and colours are compatible with those expected for central stars of planetary nebulae, and are likely to come from massive progenitor populations, and themselves be more massive than any sample of planetary nebulae known. Our survey has identified thousands of such candidates.

description: Observations of the gas component of the cloud G2 in the Galactic Center have revealed its connection to a tail (G2t) lying on the same orbit. More recent studies indicate a connection between G2 and G1, another cloud detected on the blueshifted side of G2's orbit, suggesting a scenario in which G2 is a denser clump in a stream of gas. In this Letter we show that a simulation of an outflow by a central source (possibly a T Tauri star) moving on G2's orbit and interacting with a hot atmosphere surrounding SgrA* can have G2 and G2t as a byproduct. G2 would be the bow-shock formed in the head of the source, while G2t might be the result of the stripping of the rest of the shocked material by the ram pressure of the surrounding hot gas and of its successive accumulation in the trailing region. Mock position-velocity diagrams for the Br$γ$ emission for this simulation can indeed reproduce the correct position and velocity of G2t, as well as the more tenuous material in between. Though some tension between the observations and the simulated model remains, we argue that this might be due to issues in the construction of observed position-velocity (PV) diagrams and/or to a poor treatment of some physical processes - like hydrodynamic mixing - in our simulation.

description: Copper (II) complex immobilized on the surface of silica-coated magnetic nanoparticles functionalized with di(pyridin-2-yl)amine (Fe3O4@SiO2-di(pyridin-2-yl)amine-Cu(II)) was successfully fabricated and characterized by various analyses including FT-IR, SEM, TEM, EDX, TGA, XRD, VSM, AAS and ICP-OES techniques. The catalytic behavior of Fe3O4@SiO2-di(pyridin-2-yl)amine-Cu(II) nanocomposite was investigated in the synthesis of ynones and amides. Furthermore, the heterogeneous catalyst (Fe3O4@SiO2-di(pyridin-2-yl)amine-Cu(II)) can be easily recovered by external magnet and reused for 8 cycles without significant loss in activity. The results clearly exhibit the advantages of the present methodology, namely the low catalyst loading, high product yield, experimental simplicity, broad substrate scope and short reaction times.

description: We propose a novel algorithm to compute the width of any generic $n$-body decay involving multiple off-shell particles having zero and non-zero spins. Starting from a toy example, we show the computations for three different processes that contain spin-0, $\frac{1}{2}$, and 1 off-shell particles. We have checked that our results match with the existing results at the analytical level. This proposal can be automatized and should be useful to compute the phase space for long cascade decays, without any Monte Carlo sampling.

description: Our knowledge of the chemical properties of the circumstellar ejecta of the most massive evolved stars is particularly poor. We aim to study the chemical characteristics of the prototypical yellow hypergiant star, IRC +10420. For this purpose, we obtained full line surveys at 1 and 3mm atmospheric windows. We have identified 106 molecular emission lines from 22 molecular species. Approximately half of the molecules detected are N-bearing species, in particular HCN, HNC, CN, NO, NS, PN, and N2H+. We used rotational diagrams to derive the density and rotational temperature of the different molecular species detected. We introduced an iterative method that allows us to take moderate line opacities into account. We have found that IRC +10420 presents high abundances of the N-bearing molecules compared with O-rich evolved stars. This result supports the presence of a N-rich chemistry, expected for massive stars. Our analysis also suggests a decrease of the 12C/13C ratio from \gtrsim 7 to \sim 3.7 in the last 3800 years, which can be directly related to the nitrogen enrichment observed. In addition, we found that SiO emission presents a significant intensity decrease for high-J lines when compared with older observations. Radiative transfer modeling shows that this variation can be explained by a decrease in the infrared (IR) flux of the dust. The origin of this decrease might be an expansion of the dust shell or a lower stellar temperature due to the pulsation of the star.

description: We use the explicit relation between genus filtrated $s$-loop means of the Gaussian matrix model and terms of the genus expansion of the Kontsevich--Penner matrix model (KPMM), which is the generating function for volumes of discretized (open) moduli spaces $M_{g,s}^{disc}$ (discrete volumes), to express Gaussian means in all genera as polynomials in special times weighted by ancestor invariants of an underlying cohomological field theory. We translate topological recursion of the Gaussian model into recurrent relations for coefficients of this expansion proving their integrality and positivity. As an application, we find the coefficients in the first subleading order for ${\mathcal M}_{g,1}$ for all $g$ in three ways: by using the refined Harer--Zagier recursion, by exploiting the Givental-type decomposition of KPMM, and by an explicit diagram counting.

description: Understanding heat transfer characteristics of phase change and enhancing thermal energy transport in nanoscale are of great interest in both theoretical and practical applications. In the present study, we investigated the nanoscale vaporization and condensation by using molecular dynamics simulation. A cuboid system is modeled by placing hot and cold walls in the bottom and top ends and filling with working fluid between the two walls. By setting two different high temperatures for the hot wall, we showed the normal and explosive vaporizations and their impacts on thermal transport. For the cold wall, the cuboid nanostructures with fixed height, varied length, width ranging from 4 to 20 layers, and an interval of 4 layers are constructed to study the effects of condensation induced by different nanostructures. For vaporization, the results showed that higher temperature of the hot wall led to faster transport of the working fluid as a cluster moving from the hot wall to the cold wall. However, excessive temperature of the hot wall causes explosive boiling, which seems not good for the transport of heat due to the less phase change of working fluid. For condensation, the results indicate that nanostructure facilitates condensation, which could be affected not only by the increased surface area but also by the distances between surfaces of the nanostructures and the cold end. There is an optimal nanosctructure scheme which maximizes the phase change rate of the entire system.

An analysis of the morphology and kinematics of the CSE is presented with a result very similar to that obtained earlier for $^{12}$CO(2-1) emission by Chiu et al. (2006) using the Sub-Millimeter Array. A quantitative comparison is made using their flared disk model. A new model is presented that provides a significantly better description of the data, using radial winds and smooth evolutions of the radio emission and wind velocity from the stellar equator to the poles.

description: Massive stars (those greater than 8 solar masses) are hugely important objects in our Universe. They synthesise heavy elements through and produce huge amounts of ionising radiation and distribute this into the interstellar medium. Their winds shape their local star forming regions and also affect the morphology of galactic superwinds (Leitherer 1994). Additionally, gravitational waves are the end product of massive stellar mergers, with black holes and neutron stars colliding to create ripples that are felt across the galaxy (Abbot et al 2016). The effects of a massive star can be irrevocably changed by their multiplicity. At least 90% of massive stars are expected to be in at least a binary system (e.g. Moe & di Stefano 2017) and 70% of these stars are expected to interact with eachother (e.g. Sana+ 2012). In this talk I will discuss how astrometry, particularly from spectrointerferometry with the VLTI, is now proving invaluable in the study of complicated massive binary systems. Through the presentation of two case studies, I will describe how the precise data of VLTI/GRAVITY is allowing us to break degeneracies when characterising orbits, attribute spectral features to specific stars and in doing so allow us to definitively identify massive stellar systems that have gone through interactions (e.g. Frost+ 2022) and even main sequence merger events (Frost+ 2024).

description: Measurements of the intracluster light (ICL) are still prone to methodological ambiguities and there are multiple techniques in the literature for that purpose, mostly based on the binding energy, the local density distribution, or the surface brightness. A common issue with these methods is the a priori assumption of a number of hypotheses on either the ICL morphology, its surface brightness level or some properties of the brightest cluster galaxy (BCG). The discrepancy on the results is high, and numerical simulations just bound the ICL fraction in present-day galaxy clusters to the range 10-50%. We developed a new algorithm based on the Chebyshev-Fourier functions (CHEFs) to estimate the ICL fraction without relying on any a priori assumption on the physical or geometrical characteristics of the ICL. We are able to not only disentangle the ICL from the galatic luminosity but mark out the limits of the BCG from the ICL in a natural way. We test our tecnique with the recently released data of the cluster Abell 2744, observed by the Frontier Fields program. The complexity of this multiple merging cluster system and the formidable depth of these images make it a challenging test case to prove the efficiency of our algorithm. We found a final ICL fraction of 19.17+-2.87%, which is very consistent with numerical simulations.

description: We estimate the molecular mass around CTA 1 using data from Planck and the Harvard CO survey. We observe that the molecular mass in the vicinity of the complex is not enough to explain the TeV emission observed by VERITAS, even under favorable assumptions for the cosmic-ray acceleration properties of the supernova remnant. This supports the idea that the TeV emission comes from the PWN. Here, we model the spectrum of the PWN at possible different stages of its evolution, including both the dynamics of the PWN and the SNR and their interaction via the reverse shock. We have included in the model the energy lost via radiation by particles and the particles escape when computing the pressure produced by the gas. This leads to an evolving energy partition, since for the same instantaneous sharing of the injection of energy provided by the rotational power, the field and the particles are affected differently by radiation and losses. We present the model, and study in detail how the spectrum of a canonical isolated PWN is affected during compression and re-expansion and how this may impact on the CTA 1 case. By exploring the phase-space of parameters that lead to radii in agreement with those observed, we then analyze different situations that might represent the current stage of the CTA 1 PWN, and discuss caveats and requirements of each one.

description: All the possible CP-conserving non-linear operators up to the $p^4$-order in the Lagrangian expansion are analysed here for the left-right symmetric model in the non-linear electroweak chiral context coupled to a light dynamical Higgs. The low energy effects will be triggered by an emerging new physics field content in the nature, more specifically, from spin-1 resonances sourced by the straightforward extension of the SM local gauge symmetry to the larger local group $SU(2)_L\otimes SU(2)_R\otimes U(1)_{B-L}$. Low energy phenomenology will be altered by integrating out the resonances from the physical spectrum, being manifested through induced corrections onto the left handed operators. Such modifications are weighted by powers of the scales ratio implied by the symmetries of the model and will determine the size of the effective operator basis to be used. The recently observed diboson excess around the invariant mass 1.8-2 TeV entails a scale suppression that suggests to encode the low energy effects via a much smaller set of effective operators.

description: This paper investigates optimal trading strategies in a financial market with multidimensional stock returns where the drift is an unobservable multivariate Ornstein-Uhlenbeck process. Information about the drift is obtained by observing stock returns and expert opinions. The latter provide unbiased estimates on the current state of the drift at discrete points in time. The optimal trading strategy of investors maximizing expected logarithmic utility of terminal wealth depends on the filter which is the conditional expectation of the drift given the available information. We state filtering equations to describe its dynamics for different information settings. Between expert opinions this is the Kalman filter. The conditional covariance matrices of the filter follow ordinary differential equations of Riccati type. We rely on basic theory about matrix Riccati equations to investigate their properties. Firstly, we consider the asymptotic behaviour of the covariance matrices for an increasing number of expert opinions on a finite time horizon. Secondly, we state conditions for the convergence of the covariance matrices on an infinite time horizon with regularly arriving expert opinions. Finally, we derive the optimal trading strategy of an investor. The optimal expected logarithmic utility of terminal wealth, the value function, is a functional of the conditional covariance matrices. Hence, our analysis of the covariance matrices allows us to deduce properties of the value function.

The Fermi Paradox is Neither Fermis Nor a Paradox

description: The so-called Fermi paradox claims that if technological life existed anywhere else, we would see evidence of its visits to Earth-and since we do not, such life does not exist, or some special explanation is needed. Enrico Fermi, however, never published anything on this topic. On the one occasion he is known to have mentioned it, he asked 'where is everybody?'- apparently suggesting that we don't see extraterrestrials on Earth because interstellar travel may not be feasible, but not suggesting that intelligent extraterrestrial life does not exist, or suggesting its absence is paradoxical. The claim 'they are not here; therefore they do not exist' was first published by Michael Hart, claiming that interstellar travel and colonization of the galaxy would be inevitable if intelligent extraterrestrial life existed, and taking its absence here as proof that it does not exist anywhere. The Fermi paradox appears to originate in Hart's argument, not Fermi's question. Clarifying the origin of these ideas is important, because the Fermi paradox is seen by some as an authoritative objection to searching for evidence of extraterrestrial intelligence-cited in the U. S. Congress as a reason for killing NASA's SETI program on one occasion-but evidence indicates that it misrepresents Fermi's views, misappropriates his authority, deprives the actual authors of credit, and is not a valid paradox.

description: Gravitational Microlensing has been used as a powerful tool for astrophysical studies and exoplanet detections. In the gravitational microlensing, we have two images with negative and positive parities. The negative-parity image is a fainter image and is produced at a closer angular separation with respect to the lens star. In the case of a red-giant lens star and large impact parameter of lensing, this image can be eclipsed by the lens star. The result would be dimming the flux receiving from the combination of the source and the lens stars and the light curve resembles to an eclipsing binary system. In this work, we introduce this phenomenon and propose an observational procedure for detecting this eclipse. The follow-up microlensing telescopes with lucky imaging camera or space-based telescopes can produce high resolution images from the events with reddish sources and confirm the possibility of blending due to the lens star. After conforming a red-giant lens star and source star, we can use the advance photometric methods and detect the relative flux change during the eclipse in the order of $10^{-4}-10^{-3}$. Observation of the eclipse provides the angular size of source star in the unit of Einstein angle and combination of this observation with the parallax observation enable us to calculate the mass of lens star. Finally, we analyzed seven microlensing event and show the feasibility of observation of this effect in future observations.

description: The electron-neutrino charged-current quasielastic (CCQE) cross section on nuclei is an important input parameter for electron neutrino appearance oscillation experiments. Current experiments typically begin with the muon neutrino cross section and apply theoretical corrections to obtain a prediction for the electron neutrino cross section. However, at present no experimental verification of the estimates for this channel at an energy scale appropriate to such experiments exists. We present the cross sections for a CCQE-like process determined using the MINERvA detector, which are the first measurements of any exclusive reaction in few-GeV electron neutrino interactions. The result is given as differential cross-sections vs. the electron energy, electron angle, and square of the four-momentum transferred to the nucleus, $Q^{2}$. We also compute the ratio to a muon neutrino cross-section in $Q^{2}$ from MINERvA. We find satisfactory agreement between these measurements and the predictions of the GENIE generator. We furthermore report on a photon-like background unpredicted by the generator which we interpret as neutral-coherent diffractive scattering from hydrogen.
