SUMMARY:Genomics-Driven Solutions: Harnessing the Power of Genomic Science for Controlling Antimicrobial Resistance and Infectious Diseases in Applied Engineering and Architecture
DESCRIPTION:Martedì 26 settembre dalle ore 10.00 alle ore 11.00 presso l’Aula Magna (Edificio 1 – p.za Leonardo da Vinci\, 32 – Milano) si terrà un seminario dal titolo: “Genomics-Driven Solutions: Harnessing the Power of Genomic Science for Controlling Antimicrobial Resistance and Infectious Diseases in Applied Engineering and Architecture“\, tenuto dalla Dott.ssa Elita Jauneikaite (Imperial College of London\, UK). \nDopo la presentazione la discussione finale sarà moderata da tre ricercatori del Politecnico di Milano: la Dott.ssa Beatrice Cantoni (DICA)\, il Dott. Marco Gola (DABC) e la Dott.ssa Nina Bono (DCMC). \nQuesto seminario è il risultato di una collaborazione tra questi quattro ricercatori nata all’interno della European Talent Academy (ETA)\, un’iniziativa di sviluppo del talento per potenziare la rete e la carriera dei ricercatori nella loro fase iniziale\, promossa dall’Ufficio Ricerca del Politecnico di Milano insieme alla Technical University of Munich e all’Imperial College London. \nSarà anche possibile seguire il seminario online tramite il seguente link. \nAbstract \nNearly a century after the discovery of penicillin heralded the beginning of the antibiotic era\, which has been associated with unparalleled improvements in human health and reductions in mortality associated with infection\, the dwindling pipeline for new antibiotic classes coupled with the inevitable spread of antimicrobial resistance (AMR) pose a major global challenge. Historically\, surveillance of AMR bacteria typically relied on phenotypic analysis of isolates taken from infected individuals\, which provides only a low-resolution view of the epidemiology behind an individual infection or wider outbreak. Recent years have seen increasing adoption of powerful new genomic technologies that have the potential to revolutionise AMR surveillance by provide a high-resolution picture of AMR profile of the bacteria causing infections and provide real-time actionable information for treating and preventing infections. With current DNA sequencing technologies and turnaround times\, outbreak investigation and providing support for IPC is the best use of genomics for AMR surveillance in healthcare facilities. \nI will share examples of my work on applying bacterial genomics to better understand disease-causing bacterial infections and antimicrobial resistance patterns by analysing large-scale datasets and how application of DNA sequencing technologies to investigate hospital clusters of bacterial isolates with unusual antimicrobial activity transforms our epidemiological understanding of such hospital clusters and provides novel insights into resistance vectors. \nSpeaker’s bio \nDr Elita Jauneikaite is an Advanced Research Fellow in Bacterial Genomics and Epidemiology at the Department of Infectious Disease Epidemiology at Imperial College London. She completed her PhD at the University of Southampton and the Genome Institute of Singapore before moving to Imperial College as a postdoctoral researcher and then a Research Fellow. Currently\, Dr Jauneikaite is the Research Lead for the Priority Pathogens theme at the National Institute of Health Research Health Protection Research Unit in Healthcare Associated Infection and Antimicrobial Resistance at Imperial College London. \nElita’s research focuses on evolution\, transmission and antimicrobial resistance of vaccine preventable\, and healthcare associated bacterial infections. As her major research programme\, Elita is investigating the disease-causing Group B Streptococcus (GBS) using large-scale genomic epidemiology in both high- and low-income country settings\, bioinformatic analyses and molecular biology techniques to inform on evolution\, mother-to-baby transmission\, and emergence of antimicrobial resistance patterns of this pathogen. As Research Lead for Priority Pathogens\, Elita leads genomics work investigating healthcare associated infections\, as well as outbreaks and pathogenicity of a range of bacterial pathogens including E. coli\, K. pneumoniae\, carbapenemase-producing Enterobacterales\, staphylococcal and streptococcal species. \nElita co-led the recent Surveillance and Epidemiology of Drug Resistant Infections (SEDRIC) genomic surveillance of AMR working group and is an active member of the JPIAMR B2B2B-AMRdx network. In 2022\, Elita was recognised as an Emerging Leader in International Infectious Diseases by International Society for Infectious Diseases (ISID) and selected as a participant in the European Talent Academy 2023.

SUMMARY:Uncertainty and Decision-making: Philosophical instruments at the service of Engineering
DESCRIPTION:Giovedì 28 settembre dalle ore 12.30 alle ore 13.30 presso l’Aula Fassò (Edificio 4A – p.za Leonardo da Vinci\, 32 – Milano) si terrà un seminario dal titolo: “Uncertainty and Decision-making: Philosophical instruments at the service of Engineering“\, tenuto da Malvina Ongaro (Politecnico di Milano – DICA). \nSarà anche possibile seguire l’evento online da WebEx. \nAbstract \nUncertainty is a central concept in everyday life and in most academic disciplines. In Engineering\, virtually any modelling or planning has to face uncertainty of different types and varying degrees of severity. How do we make choices under all this uncertainty\, and how should we make them? Analyses coming from theoretical research on the concept of uncertainty and on different approaches in decision-making may provide valuable tools for applied work in many areas of Engineering. \nSpeaker’s bio \nMalvina Ongaro is a postdoc researcher at Politecnico di Milano. She obtained her PhD in Philosophy from the Università del Piemonte Orientale\, where she worked mainly in decision theory and philosophy of economics. She holds a MSc in philosophy of science from the London School of Economics and has held visiting positions at the TINT Centre for Philosophy of Social Science in Helsinki and at the Erasmus Institute for Philosophy and Economics in Rotterdam. Her current interests include natural risks\, cost-benefit analysis\, and multi-criteria decision-making. \n

SUMMARY:Bio e-methane from CO2 and green H2
DESCRIPTION:Ricomincia l’appuntamento con il secondo ciclo di PhDTalks\, il primo seminario si terrà Martedì 3 ottobre in aula Fassò (Edificio 4A)\, dalle 16:30 alle 17:45 CET. \nPhDTalks è una serie di seminari e discussioni tra dottorandi. Gli eventi hanno lo scopo di fornire un luogo dove creare un network tra dottorandi ed entrare in contatto con i molti progetti sviluppati nel nostro dipartimento. \nLa speaker Anna Santus condurrà un seminario dal titolo “Bio e-methane from CO2 and green H2”.  \nAl termine dell’evento sarà disponibile un piccolo rinfresco finanziato dal dipartimento. \nSarà possibile seguire la conferenza anche online al seguente link. \nAbstract \nClimate change will have negative effects on human health\, economics\, the environment\, flora and fauna presence on the planet. For these reasons\, the necessity to find and use renewable energy sources\, such as bio e-methane\, is compelling. Bio e-methane can be generated by reducing carbon dioxide (CO2)\, a well-known greenhouse gas\, and green hydrogen (H2)\, through a biological process mediated by hydrogenotrophic methanogens (Archaea). The bio e-methane generated can be directly injected in the national natural gas grid and/or it can be used as a fuel in the transportation sector. During the PhD project\, both experimental and modelling activities of this biological process have been conducted. Experimental analysis\, carried out in batch and continuous operation\, have allowed to identify the microorganisms maximum velocity\, the optimal reactor configuration and also inhibition factors/nutrients deficiency. Modelling activities have validated experimental data collected and\, helped understanding physical aspect of gas-liquid mass of H2. Some noteworthy results achieved include: i) cultivation of hydrogenotrophic methanogens; ii) the development of a method for measuring the specific velocity of microorganisms (SHMA); iii) implementation of a model for the biological process. Looking ahead\, further insights into H2 gas-liquid mass transfer are needed to optimize the process\, as it remains a key aspect of this biological process. \nSpeaker’s bio \nAnna is a PhD student in Environmental and Infrastructure Engineering (36th cycle) at Politecnico di Milano. She has a Master of Science in Environmental and Land Planning Engineering obtained in 2019 at Politecnico di Milano. Her research activities are focused on anaerobic digestion processes and biological biogas upgrading. In her free time\, Anna loves playing soccer and hiking.

SUMMARY:Load tests on existing bridges to support safety assessment: state of the art and research perspectives
DESCRIPTION:Martedì 17 settembre dalle ore 15.00 alle ore 16.00 presso l’Aula 26.14 (Edificio 26 – Via Golgi\, 20 – Milano) si terrà un seminario dal titolo: “Load tests on existing bridges to support safety assessment: state of the art and research perspectives“\, tenuto da Daniele Losanno (Università di Napoli “Federico II” – Dipartimento di Strutture per l’Ingegneria e l’Architettura). \nAbstract \nLe prove di carico sui ponti sono tradizionalmente concepite per verificare la rispondenza del comportamento reale delle strutture a quello atteso e la risposta essenzialmente in campo elastico lineare. Negli ultimi anni a livello internazionale è stato introdotto il concetto del “bridge load testing”\, ovvero l’esecuzione di una prova di carico finalizzata a determinare una quantificazione del livello di sicurezza del ponte su base affidabilistica.  In Italia il tema risulta di particolare interesse per Gestori autostradali ed Enti locali che nei prossimi mesi dovranno implementare l’approccio multilivello previsto dalle nuove Linee Guida per la classificazione e la gestione del rischio\, la valutazione della sicurezza e il monitoraggio dei ponti esistenti. Nell’ambito del progetto che individua il Consorzio RELUIS quale soggetto attuatore della sperimentazione delle Linee Guida da parte del CSLLPP\, è attiva e in fase di sviluppo una linea di ricerca sul tema specifico. A partire dalle basi del metodo in termini di sicurezza e affidabilità strutturale rispetto a livelli di carico prescritti dalle norme\, verranno illustrate le possibili modalità di esecuzione della prova e l’importanza della definizione di soglie di allarme anche attraverso tecnologie innovative per il monitoraggio in tempo reale. Evidenziando inoltre la rilevanza di eventuali transiti eccezionali sull’opera\, saranno mostrati i risultati preliminari del caso reale di un viadotto autostradale – recentemente soggetto ad una prova di carico secondo NTC 2018 – per la valutazione degli effetti della prova sui livelli di sicurezza conseguiti. \nSpeaker’s bio \nDaniele Losanno è attualmente Ricercatore (RTDA) presso il Dipartimento di Strutture per l’Ingegneria e l’Architettura (DiST) dell’Università di Napoli “Federico II” dal 2020\, dove ha conseguito il Dottorato di ricerca nel 2015. E’ stato visiting PhD student presso la University of California Berkeley (2012) e Ricercatore presso l’Istituto delle Tecnologie della Costruzione del CNR (2019-2020). Si interessa di dinamica delle strutture per il controllo passivo delle vibrazioni con isolamento sismico e dissipazione di energia supplementare ed è PI di vari progetti di ricerca. E’ co-titolare dei corsi di Teoria e Progetto di Ponti e Monitoraggio di Strutture e Infrastrutture. E’ coinvolto in una vasta campagna sperimentale per la caratterizzazione di travi da ponte in c.a.p. a cavi post-tesi con difetti di iniezione e danneggiamento dei cavi. Ha collaborato alla redazione delle Linee Guida sui ponti esistenti nell’ambito del gruppo di lavoro sulle verifiche di sicurezza e partecipa attivamente alle attività del progetto di ricerca tra il consorzio RELUIS e il CSLLPP per la relativa sperimentazione.

SUMMARY:PhDTalks | Why should we recover P from sewage sludge? How can we get it?
DESCRIPTION:Il prossimo appuntamento con la serie di incontri PhDTalks si terrà Martedì 17 ottobre nell’aula Fassò (Edificio 4A)\, dalle 17:15 alle 18:30 CET. \nPhDTalks è una serie di seminari e discussioni tra dottorandi. Gli eventi hanno lo scopo di fornire un luogo dove creare un network tra dottorandi ed entrare in contatto con i molti progetti sviluppati nel nostro dipartimento. \nLa speaker Gaia Boniardi condurrà un seminario dal titolo “Why should we recover P from sewage sludge? How can we get it?”.  \nAl termine dell’evento sarà disponibile un piccolo rinfresco finanziato dal dipartimento. \nSarà possibile seguire la conferenza anche online al seguente link. \nAbstract  \nPhosphorus is an essential element for life and its supply is expected to be critical soon. The increasing demand for fertilizers is gradually depleting the phosphate rocks\, which are non-renewable resources concentrated in a few countries. On the other hand\, the population growth and the rapid urbanization are putting the wastewater treatment plants under strong pressure\, who are dealing with huge amounts of sewage sludge to dispose of every year. To tackle this issue\, in the view of circular economy and sustainable development\, phosphorus and nutrient recovery from sewage sludge is a promising option. The goal of this research is to optimize the phosphorous recovery from sewage sludge ash via wet chemical extraction. Experimental results underlined the influence of wastewater treatment layout and combustion process conditions on phosphorus extraction\, while the heavy metals decontamination played a fundamental role in the production of high-quality recovered material. \nSpeaker’s bio \nGaia is a PhD Candidate in Environmental and Infrastructure Engineering (36° cycle) at Politecnico di Milano. In 2020 she got a Master of Science in Environmental Engineering\, and she is currently working on nutrient recovery from waste\, in particular phosphorus from sewage sludge ash. In her free time\, she loves swimming\, surfing\, and traveling.

SUMMARY:Creep Buckling Behaviour of Concrete-filled Steel Tubular Arches
DESCRIPTION:Lunedì 23 ottobre alle ore 17.00 presso l’Aula Grandori (Edificio 4 – p.za Leonardo da Vinci\, 32 – Milano) si terrà un seminario dal titolo: “Creep Buckling Behaviour of Concrete-filled Steel Tubular Arches“\, tenuto da Yue Geng\, Professoressa di Structural Engineering presso l’Harbin Institute of Technology\, China. \nAbstract \nThe use of concrete-filled steel tubular (CFST) arches is becoming popular for bridge applications because of the increased load-carrying capacity\, convenience in construction\, and attractive appearance. Till 2023\, more than 600 CFST arch bridges have been built in China. With the improvements in material and construction techniques\, the span of newly built CFST arch bridges continues to increase\, and the longest span has reached to 600 m. As the span of CFST arch bridges increases\, the time-dependent behaviour of the core concrete in arch ribs becomes significant\, leading to considerably increase in arch deflections\, stress redistributions between steel and core concrete sections\, and even instability problems for the arches. This significant influence may trigger possible instability problems in slender CFST arches if not accurately accounted for. This presentation gains insight into the stability and creep buckling behavior of CFST arch bridges and investigates the key issues in the stability analysis of CFST arches\, including the residual stress\, the confinement effect\, the creep effect of the core concrete\, and the initial stress. This presentation also provides an accurate method to predict the time-dependent response of CFST arch bridges. \nBio-sketch \nYue Geng is Professor of Structural Engineering at Harbin Institute of Technology\, China. Prof Geng’s principal research interests lie in the composite structures and in concrete materials\, with particular research expertise on their time-dependent behaviours. Prof Yue Geng has co-authored 1 textbook\, 3 book chapters and 40 SCI journal papers\, and is good at both structural and material testing\, numerical modelling and the development of design methods. She has been granted 10 patents and software copyrights by the Chinese government. The research results have been applied to the refined design of 15 long-span or high-rise structures. She is co-chairing the Chinese design standard for recycled concrete composite structures that issued by the China Steel Construction Society. She is included in the working group for the ‘Concrete materials terminology’ standard ISO/TC 71/AHG 1 and 7 other Chinese designing codes for composite structures or recycled concrete materials. She is the editor of the International Journal of Concrete Structures and Materials. She was awarded the first prizes for scientific and technological progress by the Hei Long Jiang Province Government (2nd contributor) and by the China Steel Construction Society (3rd contributor).

SUMMARY:Recycled Aggregate Concrete Composite Structures
DESCRIPTION:Martedì 24 ottobre alle ore 14.30 presso l’Aula Grandori (Edificio 4 – p.za Leonardo da Vinci\, 32 – Milano) si terrà un seminario dal titolo: “Recycled Aggregate Concrete Composite Structures“\, tenuto da Huan Zhang\, Associate Professor di Structural Engineering presso la Scuola di Ingegneria Civile all’Harbin Institute of Technology\, Cina. \nAbstract \nNatural sand and stone resources are depleting rapidly\, and there is an urgent need to optimize the disposal methods for waste concrete. Recycled aggregate concrete (RAC) provides an effective solution to address these challenges. Steel-concrete composite structures can fully leverage the properties of materials\, compensating for the lower mechanical performance and higher discrepancies of RAC. The establishment of RAC mechanical properties models and the development of design method for steel-RAC composite structures is crucial for promoting the structural application of RAC. This presentation will delve into the influence mechanism of recycled aggregates\, discussing key issues in the development of mechanical property models for RAC and design methods for steel-RAC composite structures. Finally\, this presentation will introduce the proposed models for mechanical properties of RAC and design methods for RAC filled steel tubes and steel-RAC composite slab/beam systems\, addressing both load-carrying capacity and long-term performances. \nBio-sketch \nHuan Zhang is Associate Professor of Structural Engineering in the School of Civil Engineering at Harbin Institute of Technology. His research interests lie in the behaviours of steel-green concrete composite structures\, especially their long-term behaviours. He has published over 20 SCI/EI technical papers including Cement and Concrete Composites\, Engineering Structures\, Construction and Building Materials\, etc. He has been granted sever patents and two software copyrights by the Chinese government. He serves on the editor board of the Chinese design standard for recycled concrete composite structures (CSCS) that issued by the China Steel Construction Society. Prof. Zhang presided 5 scientific research projects\, including one project from National Natural Science Foundation of China. He was awarded the first prize for scientific and technological progress by the Hei Long Jiang Province Government. \n

SUMMARY:Behaviour of CFST Columns with Localized Corrosion Damage
DESCRIPTION:Martedì 24 ottobre alle ore 15.30 presso l’Aula Grandori (Edificio 4 – p.za Leonardo da Vinci\, 32 – Milano) si terrà un seminario dal titolo: “Behaviour of CFST Columns with Localized Corrosion Damage“\, tenuto da Chen Jia\, postdoc presso l’Harbin Institute of Technology\, Cina. \nAbstract \nDue to the outstanding structural performance\, concrete-filled steel tubes (CFST) are extensively applied in contemporary structures in marine towers\, bridge piers\, and coastal platforms. CFSTs can be subjected to localized corrosion damage during their long-time service\, because of the metallic properties of the steel tube and the corrosive medium in harsh working environments. Localized corrosion damage would cause a detrimental effect on CFST columns since it induces the continuous loss of the cross-section area of the steel tube\, as well as the loss of the confinement on the core concrete. This presentation will show the experimental and numerical investigations on CFSTs with simulated localized corrosion damage\, discuss corrosion-induced deterioration of load-carrying capacity of CFSTs\, and finally introduce the methods for predicting the residual strength of localized corroded CFSTs. \nBio-sketch \nDr. Chen Jia is now a postdoc at Harbin Institute of Technology. The main topics of her research are the post-corrosion performance of steel structures and steel-concrete composite structures. Dr. Jia presided/participated in 9 scientific research projects. She is co-author of over 20 papers published on Engineering Structures\, Thin-walled Structures\, Ocean Engineering et.al.\, and has acted as a reviewer for several scientific journals. She serves on the editor board of a design standard that issued by the China Association for Engineering Construction Standardization.

SUMMARY:Particle based simulations: from nano-chemo-mechanics to structural collapse optimization
DESCRIPTION:Mercoledì 25 ottobre alle ore 12.30 presso l’Aula Grandori (Edificio 4 – p.za Leonardo da Vinci\, 32 – Milano) si terrà un seminario dal titolo: “Particle based simulations: from nano-chemo-mechanics to structural collapse optimization“\, tenuto da Enrico Masoero (Politecnico di Milano – DICA). \nAbstract \nParticle-based simulations encompass a wide class of methods in the mechanics and physics of solids\, from molecular dynamics at the atomistic scale up to the Discrete Element method at the macroscale. A key ingredient in particle-based simulations are the interaction potentials and forces between particles; these control the dynamics and equilibrium of the simulated systems under agents such as temperature\, pressure\, chemical potentials\, applied strain\, etc. Within this framework\, the presentation will initially focus on simulating the microstructural evolution of materials under chemical reactions coupled with mechanical stress. An original Kinetic Monte Carlo simulator called MASKE will be presented to this end\, followed by applications to: (i) epitaxial nucleation and agglomeration of nanoparticles forming a mesoporous solid; (ii) stress-driven dissolution at crystallographic defects; (iii) creep and strain-dependent mechanics of nanocrystals under pressure-induced dissolution; (iv) eigenstress relaxation during cyclic deformations; (v) carbonation of calcium hydroxide as a self-healing mechanism for concrete (also mediated by bacteria); (vi) diffusion-limited dendrite growth on metal lithium electrodes. All these applications show how chemo-mechanical particle-based simulations\, when applied to the formation and degradation of microstructures\, can help gain mechanistic insight and inform the engineering models\, e.g. continuum-based ones. The presentation will then address a challenging question: can discrete simulations be combined with numerical optimization techniques to obtain structures (and microstructures) with desired properties and kinetics? A first attempt to address this question will be presented\, in the form of a software called DETO\, which extends to Discrete Element (DE) simulations the established SIMP (Solid Isotropic Material with Penalization) for Topology Optimization (TO). \nSpeaker’s bio \nEnrico Masoero is an Associate Professor at Politecnico di Milano and a member of the Mechanics of Materials and Structures group\, in the Department of Civil and Environmental Engineering. He obtained his PhD in Structural Engineering at Politecnico di Torino (2010)\, with a dissertation on particle-based simulations of building collapse. During his postdoc at MIT (2010-2013) his research shifted to the nanoscale of cement hydration. His subsequent years as a Lecturer and Senior Lecturer in the U.K. (Newcastle University 2013-2021 and Cardiff University 2021-2023) shaped his current interest in chemo-mechanical simulations and optimisation of microstructure formation and degradation. Enrico has authored various papers in international journals\, including in Physical Review Letters\, PNAS\, ACS Journal of Applied Materials and Interfaces\, and Cement and Concrete Research. He was Co-I in a large U.K. project on particle-based simulations of biomineralization (2020-2023). He is also a member of the Materials Properties committee of the Engineering Mechanics Institute\, of the American Society of Civil Engineers.

SUMMARY:PhDTalks | A fracture mechanics approach for fatigue life prediction of Ni-Ti peripheral stents
DESCRIPTION:Il prossimo appuntamento con la serie di incontri PhDTalks si terrà Martedì 31 ottobre nell’aula Fassò (Edificio 4A)\, dalle 17:15 alle 18:30 CET. \nPhDTalks è una serie di seminari e discussioni tra dottorandi. Gli eventi hanno lo scopo di fornire un luogo dove creare un network tra dottorandi ed entrare in contatto con i molti progetti sviluppati nel nostro dipartimento. \nLa speaker Alma Brambilla condurrà un seminario dal titolo “A fracture mechanics approach for fatigue life prediction of Ni-Ti peripheral stents”.  \nAl termine dell’evento sarà disponibile un piccolo rinfresco finanziato dal dipartimento. \nSarà possibile seguire la conferenza anche online al seguente link. \nAbstract  \nNickel-Titanium (Ni-Ti) stents are the gold standard in the mini-invasive treatment of atherosclerotic diseases affecting peripheral arteries. The fatigue fracture of these devices under in vivo cyclic loads constitutes an open issue of major concern given the severe associated drawbacks such as re-occlusion of the artery. However\, the non-linear material response and the reduced dimensions of stent struts increase the complexity of their fatigue assessment\, requiring ad hoc and well-defined methods. Despite many phenomenological approaches have been proposed\, open questions remain and more efforts are still required to understand and predict Ni-Ti thin struts failure under fatigue loads. This work aims at investigating the application of fracture mechanics principles for stent fatigue life assessment\, accounting for the propagation of pre-existing manufacturing defects. To this purpose\, crack propagation tests were performed on ad hoc samples\, characterized by a microstructure comparable to that of stents\, to gain the material crack growth rate. A proof-of-concept study was conducted at first\, performing an experimental fatigue campaign on multi-wires samples having the same dimension and material properties of stents. Fracture surfaces were inspected through a scanning electron microscope highlighting defect size at the initiation site of fracture. A crack propagation algorithm was herein calibrated\, introducing the non-linear fracture mechanics energetic parameter cyclic J-integral and integrating the crack growth law from the initial defect size observed on the fracture surfaces. Finally\, the same approach was adopted to predict the fatigue life of commercially-resembling stents (Fig. 1)\, experimentally tested under multi-axial loading conditions\, exploiting finite element simulations to assess the local cyclic stress-strain response in the failure regions. In both the studied applications\, promising life predictions were obtained\, demonstrating the role of fracture mechanics in explaining Ni-Ti struts fatigue failure. \nSpeaker’s bio \nAlma is a PhD student in Structural\, Seismic\, and Geotechnical Engineering (38th cycle) at Politecnico di Milano. She has a Master of Science in Biomedical and Mechanical Engineering obtained in 2022 at Politecnico di Milano through a Double Degree Programme.Her current research mainly addresses experimental characterization and numerical modeling of the fatigue behavior of cardiovascular devices made by Nickel-Titanium shape memory alloys\, focusing on the development of integrated predictive tools to assess fracture.\nIn her free time\, Alma enjoys hiking and reading.

SUMMARY:PhDTalks | Innovative methodologies to support the implementation of sustainable wastewater reuse in agriculture: risk and impacts assessment
DESCRIPTION:Il prossimo appuntamento con la serie di incontri PhDTalks si terrà Martedì 14 novembre nell’aula Fassò (Edificio 4A)\, dalle 17:15 alle 18:30 CET. \nPhDTalks è una serie di seminari e discussioni tra dottorandi. Gli eventi hanno lo scopo di fornire un luogo dove creare un network tra dottorandi ed entrare in contatto con i molti progetti sviluppati nel nostro dipartimento. \nLo speaker Luca Penserini condurrà un seminario dal titolo “Innovative methodologies to support the implementation of sustainable wastewater reuse in agriculture: risk and impacts assessment”.  \nAl termine dell’evento sarà disponibile un piccolo rinfresco finanziato dal dipartimento. \nSarà possibile seguire la conferenza anche online al seguente link. \nAbstract  \nWater pollution and scarcity of clean freshwater\, exacerbated by climate change and population growth\, are posing a global risk not only limited to the environment\, but also involving human health and related socio-economical aspects\, raising a need for sustainable water management practices. The reuse of reclaimed wastewater (RWW)\, especially for agriculture\, i.e.\, the most water demanding sector\, has been recognized as a reliable alternative source to conventional freshwater. Either direct and indirect reuse of RWW inherently connects water in numerous environmental compartments (i.e.\, raw water\, soil\, crop). This interconnection leads to a series of impacts\, either positive\, as the water stress alleviation or the enhancement of agricultural productivity through the supply of nutrients\, or negative\, as the cross-contamination of different environmental compartments with contaminants of emerging concern (CECs)\, pathogens and antibiotic resistance genes (ARGs) and antibiotic resistant bacteria (ARBs). All these impacts need to be evaluated through specific models to avoid\, or at least\, mitigate\, potential long-term risks. \nWastewater treatment plants (WWTPs) assume a crucial role in determining the quality of RWW intended for irrigation\, especially considering the compliance requisites delineated in the regulation on minimum requirements for water reuse adopted in June 2023 by the European Parliament (Regulation 2020/741). Moreover\, in this regulation it is stressed the need for a shift from the common practice of establishing minimum quality requirements towards preventive risk analysis aimed at minimizing risks and maximizing positive impacts throughout all the steps of the RWW reuse chain. \nIn this context\, the present project is aimed at developing a holistic risk-based framework for the integrated assessment of RWW reuse practices’ impacts\, to support decision-makers and water utilities in planning\, design and comparing the different alternatives and determine the optimum solutions to minimize risks and social costs. \nSpeaker’s bio \nLuca is a PhD student in Environmental and Infrastructure Engineering (37th cycle) at Politecnico of Milan. He has a Master of Science in Environmental and Land Planning Engineering obtained in 2020 at Politecnico of Milan. \nLuca works in the safeWATER research group and his research activities focus on the impacts modelling of wastewater reuse in agriculture practices\, emphasizing risk assessment procedures as a key focal point. \nIn his free time\, Luca loves playing sports and travelling.

SUMMARY:PhDTalks | Flood Risk Mitigation through Smart Levee Solutions based on Fiber Optic Sensors: An Applied Case Study in Emilia-Romagna
DESCRIPTION:Il prossimo appuntamento con la serie di incontri PhDTalks si terrà Martedì 28 novembre nell’aula Fassò (Edificio 4A)\, dalle 17:15 alle 18:30 CET. \nPhDTalks è una serie di seminari e discussioni tra dottorandi. Gli eventi hanno lo scopo di fornire un luogo dove creare un network tra dottorandi ed entrare in contatto con i molti progetti sviluppati nel nostro dipartimento. \nLo speaker Manuel Bertulessi condurrà un seminario dal titolo “Flood Risk Mitigation through Smart Levee Solutions based on Fiber Optic Sensors: An Applied Case Study in Emilia-Romagna”.  \nAl termine dell’evento sarà disponibile un piccolo rinfresco finanziato dal dipartimento. \nSarà possibile seguire la conferenza anche online al seguente link. \nAbstract  \nThe Smart Levee concept is an increasingly emerging practice applied to the monitoring of the serviceability and stability of riverbanks\, a strategic asset for flood risk management in lowland areas. The levee smartness is given by a network of different kinds of sensors installed on site that\, through a data interpretation layer\, provide continuous information about the health conditions of the structure and its response to external solicitations. This approach can bring a strong improvement to the efficiency of the maintenance procedures\, as well as to the surveillance procedures during flood events. \nWe adopt this concept by conceiving an anti-erosion levee sensing revetment\, based on the integration between a geomat reinforced with double twist wire mesh and Polymeric Fiber Optic Sensors (PFOS). The project\, financed by the Agency for Territorial Safety and Civil Protection of the Emilia-Romagna Region\, has been supported by Fondazione Politecnico di Milano\, University of Padua (DICEA)\, Officine Maccaferri Spa ed Optosensing Srl. \nLab experiments and finite element modeling have been performed to select the best coupling solution of PFOS to the reinforced geomat\, hence design the layout of the sensing revetment. A prototype of this technology has been installed\, both landside and riverside\, on a 25 m linear length portion of the levee bank of the Grizzaga creek in Fossalta\, by the town of Modena in Emilia-Romagna Region. This area hosts one of the most critical nodes of the fluvial network of the region and was hit by floods frequently in the past. The experimental site has been also equipped with some agronomic and geotechnical sensors to investigate the mechanical behavior of the levee when it is subjected to external solicitations – e.g. those caused by a flood event – hence\, improving the response of the monitoring solution. Moreover\, we designed and installed below sensing revetments placed riverside a testing system based on a set of pneumatic cushions that will be used to exert locally controlled soil deformation. \nThe system successfully passed an important stress test during the heavy flood events that hit the Region in May 2023\, detecting properly all the evolution of the flood wave. Further investigations are still ongoing\, both with on-site tests and laboratory activities to characterize the sensibility of the monitoring solution to different kinds of possible solicitations. \nSpeaker’s bio \n\nManuel is a PhD student in Environmental and Infrastructure Engineering (37th cycle) at Politecnico di Milano. He got his MSc Degree in Environmental and Land Planning Engineering in 2019 at Politecnico di Milano. \n\n\nManuel’s research activity deals with the conceptualization of innovative monitoring solutions based on Fiber Optic Sensors for critical hydraulic infrastructures. \n\n\nIn his free time\, Manuel loves travelling and hiking.

SUMMARY:PhDTalks | Severe spalling in heated concrete
DESCRIPTION:Il prossimo appuntamento con la serie di incontri PhDTalks si terrà Martedì 12 dicembre nell’aula Fassò (Edificio 4A)\, dalle 17:15 alle 18:30 CET. \nPhDTalks è una serie di seminari e discussioni tra dottorandi. Gli eventi hanno lo scopo di fornire un luogo dove creare un network tra dottorandi ed entrare in contatto con i molti progetti sviluppati nel nostro dipartimento. \nLo speaker Rammin Yarmohammadian condurrà un seminario dal titolo “Severe spalling in heated concrete”.  \nAl termine dell’evento sarà disponibile un piccolo rinfresco finanziato dal dipartimento. \nSarà possibile seguire la conferenza anche online al seguente link. \nAbstract \nThere is no doubt that concrete will continue to be utilized as a construction material much into the future as it is now the most often used building material. Thanks to its low conductivity\, it is known to exhibit good behaviour in fire. However\, the fact that concrete is prone to the spalling phenomenon when exposed to fire poses a significant obstacle to its widespread utilization. Explosive spalling keeps being one of the main open issues concerning the fire safety of concrete structures. Though it is recognized that cracks in the exposed cover can be triggered by the combined effect of thermal stress and pore pressure\, the energy source and the mechanism behind the violent projection of fragments are not yet fully understood. in the scope of this presentation\, the latest experimental and numerical results in understanding such complex behavior are presented. \nSpeaker’s bio \nRamin Yarmohammadian is currently a PhD student of the DICA 36th cycle\, titled “Severe spalling in concrete exposed to fire”. He is interested in both experimental and numerical analysis of fire-induced spalling and fracture behaviour of concrete material. As a graduate student\, he investigated spalling using Neutron radiography (NR) techniques to verify the role of moisture in such an event which was also confirmed by the thermo-hygro-mechanical model.   \nIn his PhD research\, new experimental tests were designed not only to rank different concrete mixes (screening tests) but also to shed light on the real mechanism engaged in this event. He also investigated the fracture behaviour of concrete using a new direct tensile test setup (3ACTION) which can control crack opening not to have secondary bending.    \nIn his free time\, he likes to travel and spend time with friends and family.

SUMMARY:PhDTalks | Integrating Probabilistic Hydrogeological Reconstruction and Groundwater Flow Modeling for the Po Plain Aquifer System: A Data-Driven Approach Supporting Physics-Based Modeling
DESCRIPTION:Il prossimo appuntamento con la serie di incontri PhDTalks si terrà Martedì 9 gennaio nell’aula Fassò (Edificio 4A)\, dalle 17:15 alle 18:30 CET. \nPhDTalks è una serie di seminari e discussioni tra dottorandi. Gli eventi hanno lo scopo di fornire un luogo dove creare un network tra dottorandi ed entrare in contatto con i molti progetti sviluppati nel nostro dipartimento. \nLo speaker Andrea Manzoni condurrà un seminario dal titolo “Integrating Probabilistic Hydrogeological Reconstruction and Groundwater Flow Modeling for the Po Plain Aquifer System: A Data-Driven Approach Supporting Physics-Based Modeling”.  \nAl termine dell’evento sarà disponibile un piccolo rinfresco finanziato dal dipartimento. \nSarà possibile seguire la conferenza anche online al seguente link. \nAbstract \nI present a study related to the modeling of large-scale groundwater flow and contaminant transport in porous media. The techniques presented are designed to efficiently handle a large volume of data by combining knowledge of system physics with the increasingly availability of innovative artificial intelligence techniques. The study is divided into three main phases. \nIn the first phase\, a probabilistic hydrogeological reconstruction is carried out on a large-scale system\, specifically for the Po River basin in Italy. This reconstruction is accomplished using artificial intelligence techniques that have been appropriately adapted to realize the hydrogeological reconstruction and quantify its associated uncertainty. These findings serve as input for the second phase of the study\, which focuses on developing a flow model. To achieve this\, we have developed a methodology for calibration and sensitivity analysis of large-scale groundwater flow models. This methodology includes the application of state-of-the-art optimization algorithms and posterior sensitivity analysis\, which provide information on the sensitivity of the model output (hydraulic load) to variations in parameter values after the calibration phase. The case study for this methodology is the Po River basin\, for which a groundwater flow model has been developed based on available measurements in the region\, including hydraulic head measurements\, satellite precipitation data\, temperature\, land use\, and continental-scale models of soil properties and crops. \nFinally\, the third phase focuses on the development of a deep learning-based methodology aimed at identifying preferential pathways for contaminants in porous media and utilizing the information within these pathways to determine the arrival time of the first quantity of contaminant in a region of interest. This methodology serves as a foundation for the development of artificial intelligence-based methodologies for identifying pathways and travel times of contaminants within aquifers in highly complex systems\, as the system analyzed in the first two phases of this study. \nSpeaker’s bio \nAndrea Manzoni is a Ph.D. candidate in Environmental and Infrastructure Engineering at Politecnico di Milano\, with a Master of Science in Energy Engineering\, specializing in oil and gas production from the same institution. \nHis research covers a diverse range of topics. This includes complex models\, groundwater flow\, contaminant transport\, large-scale models\, stochastic inverse modeling\,  sensitivity analysis\,  multiphase flow\, data mining\, remote sensing and on-site data analysis\, applied machine learning\, and computer vision. \nHis Ph.D. thesis focuses on developing a stochastic inverse modeling technique for a large-scale groundwater flow model applied to the groundwater system of the Po River watershed\, as well as a deep learning technique for contaminant transport through porous media. \nIn 2023\, Andrea Manzoni further enriched his expertise as a Visiting Scholar for 5 months at the University of Southern California (Los Angeles\, US). During this time\, he focused on contaminant transport\, the cutting-edge applications of artificial intelligence techniques in computer vision and image processing\, and uncertainty quantification applied to machine learning models. \nIn addition\, Andrea Manzoni has held the position of Vice-President of the Society of Petroleum Engineers (SPE) Student Chapter at Politecnico di Milano since 2021.

SUMMARY:Flood hazard mapping: the HORA project
DESCRIPTION:Mercoledì 31 gennaio dalle ore 10.35 alle ore 11.20 presso l’Aula Grandori (Edificio 4 – p.za Leonardo da Vinci\, 32 – Milano) si terrà un seminario dal titolo: “Flood hazard mapping: the HORA project“\, tenuto dal Prof. Günter Bloeschl (TU Wien\, Institute of Hydraulic Engineering and Water Resources Management). \nA seguire\, dalle ore 11.30 alle ore 12.30 si terrà una discussione a tavolino con il Prof. Günter Bloeschl\, il Prof. Renzo Rosso e il Prof. Giovanni Menduni dove verrà affrontata la domanda: “Which design recommendations are suitable for flood hazard mitigation in urbanized territory under climate change meteorological forcing?” \nSarà possibile seguire il seminario online al seguente link. \nAbstract \nFlood hazard mapping is currently in a transitional phase involving the use of data and methods that were traditionally the domain of local studies in a regional or nation-wide context. Challenges include the representation of local information such as hydrological particularities and small hydraulic structures\, and computational and labour costs. This paper proposes a methodology of flood hazard mapping that merges the best of the two worlds (local and regional studies) based on experiences in Austria. The analysis steps include (a) quality control and correction of river network and catchment boundary data; (b) estimation of flood discharge peaks and volumes on the entire river network; (c) creation of a digital elevation model (DEM) that is consistent with all relevant flood information\, including river bed geometry; (d) simulation of inundation patterns and velocities associated with a consistent flood return period along the entire river network. In each step\, automatic methods are combined with manual interventions in order to maximise the efficiency and at the same time ensure estimation accuracy similar to that of local studies. The accuracy of the estimates is evaluated in each step. The study uses flood discharge records from 781 stations to estimate flood hazard patterns of a given return period at a resolution of 2 m over a total stream length of 38000 km. It is argued that a combined local-regional methodology will advance flood mapping\, making it even more useful in nation-wide or global contexts.

SUMMARY:PhDTalks | Healing capacity of Ultra High Performance Concrete under sustained through crack tensile stresses and aggressive environments
DESCRIPTION:Il prossimo appuntamento con la serie di incontri PhDTalks si terrà Martedì 6 febbraio nell’aula Fassò (Edificio 4A)\, dalle 17:15 alle 18:30 CET. \nPhDTalks è una serie di seminari e discussioni tra dottorandi.

Specifically\, it delves into the long-term self-healing process in pre-cracked UHPC samples that endure continuous sustained tensile stresses across the cracks and are exposed to aggressive environmental conditions for one year. This study not only emphasizes that pre-cracked UHPC\, when exposed to both mechanical stresses and aggressive environments\, can maintain excellent durability and mechanical strength due to its self-healing effect but also lays the foundation for evaluating the self-healing potential of cement-based materials under conditions representative of real-world structural scenarios. \nSpeaker’s bio \nBin is a PhD candidate in the 36th cycle of SSGE at Politecnico di Milano. He holds a master’s degree in civil engineering from Shenzhen University\, China. His current research focuses on the realms of self-healing and durability within the context of fiber-reinforced concrete. Outside the academic sphere\, Bin is passionate about exploring new horizons. Traveling and hiking are his preferred avenues for relaxation and personal enrichment.

SUMMARY:Bayesian assessment of existing concrete structures: dealing with different types of information and challenges for the future
DESCRIPTION:Venerdì 9 febbraio alle ore 11.00 presso l’Aula Castigliano (Edificio 5 – p.za Leonardo da Vinci\, 32 – Milano) si terrà un seminario dal titolo: “Bayesian assessment of existing concrete structures: dealing with different types of information and challenges for the future“\, tenuto dal Prof. Robby Caspeele (Magnel-Vandepitte Laboratory\, Department of Structural Engineering and Building Materials\, Ghent University\, Belgium). \nAbstract \nAn increasing amount of the current activities in the construction sector are oriented towards the assessment of existing structures and the associated repair and upgrading interventions. Although the last decennia significant progress has been made to analytically and numerically simulate the degradation process of concrete structures and their associated structural performance prediction in time\, structural engineers are challenged to deal with the large uncertainties involved. Besides a typical lack of information\, the degradation processes are associated with large uncertainties and when executing additional investigations and measurements\, significant model and measurement uncertainties play a dominant role in the reliability-based performance prediction. Bayesian updating techniques provide a unique engineering tool\, enabling to make inferences where classical statistical approaches fail. It is explained and illustrated how Bayesian updating techniques provide an undeniable advantage in several steps of the assessment process. Degradation models whose parameters generally are difficult to find consensus about\, can gradually be updated when more information becomes available. Variables in structural reliability calculations can be updated on the basis of direct as well as indirect measurement data. Sources of information contained in different types of measurements or even visual inspections can be combined in order to make much more informed inferences and to reduce uncertainties in the reliability-based performance assessment\, compared to when such data is analysed separately. The integration of these approaches into the practical assessment process is proven to be feasible and an outlook is given on future engineering challenges to integrate such approaches further in the life-cycle assessment of existing concrete structures. \nSpeaker’s bio \nRobby Caspeele is a professor in the field of Structural Reliability at Ghent University (UGent) since 2013 and one of the technical directors of the Magnel-Vandepitte Laboratory for Structural Engineering and Building Materials. He received his MSc degree in Civil Engineering in 2006 and his PhD in Civil Engineering in 2010. His main areas of expertise relate to (1) full- and semi-probabilistic structural reliability methods and Bayesian updating techniques in relation to performance-based life-cycle analysis of concrete structures\, (2) structural robustness and membrane action in concrete structures in relation to design against progressive collapse as a result of foreseen and unforeseen events and (3) structural assessment of existing structures in relation to time-dependent degradation\, combining numerical structural analysis approaches with Bayesian updating techniques\, decision making for structural interventions and lifetime performance optimization. He is author of more than 75 publications in peer-reviewed journals and over 200 papers in international scientific conference proceedings. He is also strongly involved in international committees and working groups related to the development of technical guidelines and standards. Among others\, he is a board member of the Joint Committee on Structural Safety\, co-convenor of fib Commission 3 on Existing Structures and chair of the Belgian mirror committee for the Eurocodes.

SUMMARY:PhDTalks | Managing (micro-)pollutants contamination in integrated urban wastewater systems: risk assessment and mitigation strategies
DESCRIPTION:Il prossimo appuntamento con la serie di incontri PhDTalks si terrà Martedì 20 febbraio nell’aula Fassò (Edificio 4A)\, dalle 17:15 alle 18:30 CET. \nPhDTalks è una serie di seminari e discussioni tra dottorandi.

Concurrently\, diverse user demands have determined the competition for clean water resources\, exacerbated by severe droughts caused by climate change. \nIn highly urbanized areas\, water can be used for different purposes\, discharging very different types of (micro-)pollutants into the sewer system or directly to surface water. In fact\, these systems are often combined and when rain events hit the city\, they can reach their capacity\, discharging untreated wastewater and stormwater directly into water bodies\, causing pollutants overload. Moreover\, wastewater treatment plants (WWTP) are currently designed to remove only conventional pollutants\, spreading micropollutants in the environment also in dry-weather. In this way\, different type of contaminants can reach surface water and move across different water sources and compartments. They can accumulate in groundwater and surface water\, where they can also be transferred due to crop irrigation. The complexity in contamination sources\, pathways\, and receptors make urban water management intricate. Correct and well-planned water management is crucial to avoid conflicts among different stakeholders and to limit the risk for the environment and human health. \nTo address these issues\, the present project aims at developing a comprehensive framework for assessing and managing (micro-)pollutants risks in urban water\, modeling their fate and transport across various water sources and compartments\, while also exploring suitable treatment technologies for wet-weather discharges and WWTP effluent. \nSpeaker’s bio \nJessica is a PhD student in Environmental and Infrastructure Engineering (37th cycle) at Politecnico di Milano. She has a Master of Science in Environmental and Land Planning Engineering obtained in 2021 at Politecnico di Milano. \nJessica works in the safeWATER research group and her research activity focuses on modelling fate and transport of micropollutants in urban water\, assessing the environmental risk and evaluating proper mitigation strategies. \nIn her free time she loves enjoying nature\, playing the piano\, and travelling.

SUMMARY:Advancements in Bayesian Neural Networks to Enhance Predictive Modeling for Civil Engineering Applications
DESCRIPTION:Giovedì 22 febbraio alle ore 11.00 presso l’Aula Fassò (Edificio 4A – p.za Leonardo da Vinci\, 32 – Milano) si terrà un seminario dal titolo: “Advancements in Bayesian Neural Networks to Enhance Predictive Modeling for Civil Engineering Applications“\, tenuto dalla Prof.ssa Audrey Olivier (Sonny Astani Department of Civil and Environmental Engineering\, University of Southern California). \nAbstract \nThe conjuncton of data mining and physics-based modeling holds great potential to help design\, monitor and optimize civil infrastructure systems. Machine learning (ML) tools can be used for a variety of civil engineering applications\, from monitoring the health of structures using sensing data to building efficient surrogates to accelerate mechanistic modeling. The use of ML models for scientific and engineering applications presents unique challenges. Engineering datasets are often noisy\, sparse and imbalanced\, due to the inherent randomness of the underlying physical processes and constraints on data collection. ML predictors must also assimilate physics-based knowledge and intuitions to improve accuracy and generalization away from training data. Finally\, ML models must embed robust prediction of uncertainties to improve trustworthiness for high-consequence decision-making. Framing ML training within a Bayesian inference framework allows for a robust quantification of both aleatory and epistemic uncertainties that arise from data inadequacies\, integration of physics intuitions through prior design\, and assessment of the model’s confidence in its predictions. However\, due to the high-dimensionality and non-physicality of parameters that characterize typical ML models such as neural networks\, application of Bayesian methods in this context raises several challenges\, from prior and likelihood design to posterior inference. In this talk I will present some of the methods we have developed for approximate Bayesian learning of neural networks that integrate meaningful physics-driven priors. I will illustrate the benefits of these methods through a variety of example applications in civil engineering\, from surrogate training to accelerate materials and structural modeling\, contingency analysis in power grid systems\, or ambulance travel time prediction in a dense urban network to help optimize emergency medical services. \nShort Bio \nDr. Olivier holds a Diplôme d’Ingénieur from École Centrale de Nantes\, France\, and a Ph.D. in Civil Engineering and Engineering Mechanics from Columbia University\, USA. She held a postdoctoral appointment at Johns Hopkins University before joining the Sonny Astani Department of Civil and Environmental Engineering at the University of Southern California as an Assistant Professor in Fall 2021. Dr. Olivier’s research aims to predict and monitor civil infrastructure systems behavior under uncertainty\, by combining innovations in probabilistic data analytics and mechanistic modeling. Applications span various scales\, from systems to structures to materials\, and include development of adaptive Bayesian filters for identification of dynamical structural systems\, probabilistic surrogate models to accelerate multi-scale materials simulations or Bayesian graph neural networks for contingency analysis of power grids.\nAdditional information available at: https://www.audreyolivier.com/; https://viterbi.usc.edu/directory/faculty/Olivier/Audrey .

SUMMARY:PhDTalks | A Mixed-dimensional solver for the geoelectrical analysis of highly resistive liners in landfills
DESCRIPTION:Il prossimo appuntamento con la serie di incontri PhDTalks si terrà Martedì 27 febbraio nell’aula Fassò (Edificio 4A)\, dalle 17:15 alle 18:30 CET. \nPhDTalks è una serie di seminari e discussioni tra dottorandi. Gli eventi hanno lo scopo di fornire un luogo dove creare un network tra dottorandi ed entrare in contatto con i molteplici progetti sviluppati nel nostro dipartimento. \nLo speaker Lorenzo Panzeri condurrà un seminario dal titolo “A Mixed-dimensional solver for the geoelectrical analysis of highly resistive liners in landfills”.  \nAl termine dell’evento sarà disponibile un piccolo rinfresco finanziato dal dipartimento. \nSarà possibile seguire la conferenza anche online al seguente link. \nAbstract \nThe analysis of the condition of the liner beneath municipal waste landfills is of considerable importance to prevent the spread of pollutants into the underlying layers down to the groundwater zone. Being at depths of several tens of metres in an uncertain location\, it is crucial to find an effective method for its identification. \nDirect current (DC) methods\, in particular ERT (Electric Resistivity Tomography)\, exploit the conductive and resistive properties of the materials\, permitting the identification of both the location of the highly resistive HDPE (High density polyethylene) membrane and the possible diffusion area of the pollutant\, which\, due to its high salt content\, is highly conductive.  A new mixed-dimensional Finite volume numerical model is developing for solving the forward and inverse problems in DC resistivity surveys. \nSpeaker’s bio \nLorenzo is a PhD Candidate in Environmental and Infrastructure Engineering (37° cycle) at Politecnico di Milano with an interdisciplinary scholarship between the Department of Civil and Envirnomental Engineering and the Department of Mathematics. Lorenzo has a Master of Science in Civil Engineering For Risk Mitigation obtained in 2019. In his free time\, Lorenzo loves playing football and doing trail running.

SUMMARY:PhDTalks | Integrating optical and radar imaging to enhance river drought monitoring
DESCRIPTION:Il prossimo appuntamento con la serie di incontri PhDTalks si terrà Martedì 5 marzo nell’aula Fassò (Edificio 4A)\, dalle 17:15 alle 18:30 CET. \nPhDTalks è una serie di seminari e discussioni tra dottorandi. Gli eventi hanno lo scopo di fornire un luogo dove creare un network tra dottorandi ed entrare in contatto con i molti progetti sviluppati nel nostro dipartimento. \nLo speaker Stefano Conversi condurrà un seminario dal titolo “Integrating optical and radar imaging to enhance river drought monitoring”.  \nAl termine dell’evento sarà disponibile un piccolo rinfresco finanziato dal dipartimento. \nSarà possibile seguire la conferenza anche online al seguente link. \nAbstract \nDrought events are growingly affecting European and Italian territories\, hampering local environments and biodiversity\, such as the ones relying on rivers for their subsistence. Monitoring of rivers is becoming an important issue to face drought crisis and may be exploited with different tools. Among the most commons\, satellite imagery is exploited to map water coverage\, basing on optical or radar sources. This work proposes a combination of the two sensors to overcome possible limitations of the single dataset exploitation\, reaching a reliable result. The methodology is applied to a stretch of Po River in Lombardy region (Italy). Through Google Earth Engine platform\, optical satellite Sentinel-2 and radar satellite Sentinel-1 data are processed. The combination of the radar data and of the optical spectral indices is carried out through a pixel-based supervised classification\, with a Random Forest classifier. Maps of water coverage are obtained\, numerical outcomes of water surface evaluation are recorded and validated by the mean of reference hydrometric data. A multitemporal analysis is then reported\, aiming to prove the efficiency of the procedure. All iterations show reliable accuracies and correlation among water surface estimation and water table measurements in two sections of interest. In perspective\, the proposed methodology will be implemented in tools for supporting drought monitoring to be integrated in environmental public administration policies. \nSpeaker’s bio \nStefano is a PhD Student in Environmental and Infrastructure Engineering\, within the Geodesy and Geomatics section. In 2021 he obtained the Master degree in Civil Engineering for Risk Mitigation at Politecnico di Milano. Currently he is part of the Innovazione project supported by Politecnico and Regione Lombardia\, for which he collaborates with the Operative Unit for management and preservation of Biodiversity.D Stefano likes to spend his free time travelling\, attending live concerts and baking.
