SUMMARY:PhDTalks | Timber for Hybrid Structures: an innovative perspective from numerical modeling to environmental assessment
DESCRIPTION:Il prossimo appuntamento con la serie di incontri PhDTalks si terrà Martedì 2 Maggio nell’aula 2.1.3 (Edificio 2)\, 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 Laura Corti condurrà un seminario dal titolo “Timber for Hybrid Structures: an innovative perspective from numerical modeling to environmental assessment”.  \nAl termine dell’evento sarà disponibile un piccolo rinfresco finanziato dal dipartimento. \nSarà possibile seguire la conferenza anche online al seguente link. \nAbstract: \nIn the current context of climate change\, structural engineers struggle every day with an alarming fact: building sector contributes to 30% of global greenhouse emissions. One of the developing topic of research is characterised by bio-based structural materials\, in particular timber and engineered wood. Hybridisation of timber with other materials provides many advantages\, as better performances e.g. in case of seismic loads\, minor construction times and lower environmental impact. The topic of this talk focuses of some innovative research aspects of timber-hybrid structures\, first of all considering some numerical modeling benchmark analyses with issues specifically linked with timber orthotropy and contacts among other materials and secondly a comparative Life Cycle Assessment analysis where two equivalent buildings are compared and the role of connectors is highlighted. The perspective of this presentation suggests an overview of the interdisciplinarity of this topic\, where traditional structural problems are tackled together with sustainability issues. \nSpeaker’s bio: \nLaura graduated with a Master in Civil Engineering for Risk Mitigation (CERM) in Politecnico di Milano in 2021. She is currently enrolled in the second year of the PhD programme in Structural\, Seismic\, and Environmental Engineering (XXXVII cycle) at the Department of Civil and Environmental Engineering of Politecnico di Milano. She is involved in the modeling\, testing and development of timber-concrete hybrid composites\, with a special focus on sustainability. In the free time Laura enjoys going to the theater\, hiking and swimming.

SUMMARY:PhDTalks | Acceleration of high-resolution simulations of pollutants dispersion in atmosphere performed with a Lagrangian Particle Dispersion Model
DESCRIPTION:Il prossimo appuntamento con la serie di incontri PhDTalks si terrà Martedì 30 Maggio nell’aula 2.1.3 (Edificio 2)\, 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 Daniela Barbero condurrà un seminario dal titolo “Acceleration of high-resolution simulations of pollutants dispersion in atmosphere performed with a Lagrangian Particle Dispersion Model”.  \nAl termine dell’evento sarà disponibile un piccolo rinfresco finanziato dal dipartimento. \nSarà possibile seguire la conferenza anche online al seguente link. \nAbstract: \nAtmospheric dispersion modelling is becoming increasingly important for the air quality assessment of urban environments\, especially in residential areas\, for regulatory purposes and to project pollution control strategies. Estimating urban air quality is challenging\, because of the intrinsic characteristics of cities atmospheric structure\, such as high density of primary emissions and presence of local dispersion processes\, that produce strong concentration gradients. Therefore\, very high spatial resolution simulations may often be required to improve the accuracy of estimations. Consequently\, the use of microscale atmospheric dispersion models in long-term studies and forecasting systems is growing. However\, this modelling can be ambitious because of the amount of time and CPU required for the simulations\, especially if the computational domain has a significant extension. \nThis work presents the use of kernel method as alternative to the common box-counting method to compute concentration inside the microscale Lagrangian Particle Dispersion Model PSPRAY. The kernel method allows a reduction of computational particles emitted during the simulation; it enables therefore to optimize the overall computational costs of the simulation\, ensuring at the same time results with an accuracy similar to that of box counting method. \nThe method has been tested to compute hourly ground concentration and deposition fields of gaseous and particulate pollutants emitted by point and linear sources\, evaluated both inside a domain divided in tiles and inside a nested domains configuration. The implementation inside PSPRAY has made possible to reduce the computational time of a simulation from 70% to 80%. Therefore\, it led to an enhancement of the efficiency of model and to a widening of its application field. \nThe PSPRAY model\, optimized with the kernel method\, has been already extensively applied to evaluate the impact of road emissions in the city of Rome\, in the frame of Italian research project BEEP (Big data in Environmental and occupational Epidemiology). This implementation allowed to perform a microscale simulation over the city\, considering a 12×12 km2 domain with a horizontal resolution of 4 m and producing hourly ground concentration fields of the pollutants for an entire year\, obtaining an average computational time of 3 hours per simulated day on an HPC (High Performance Computing) system with 180 cores. \nSpeaker’s bio: \nDaniela is a candidate of an Executive PhD in Environmental Engineering and Infrastructure (35° cycle) at Politecnico di Milano in collaboration with ARIANET s.r.l.\, of which she has been an employee since 2019\, after obtaining a Master of Science in Environmental And Land Planning Engineering at Politecnico di Milano. \nARIANET is an Italian consultant company in the field of atmospheric environment and Daniela is involved both in carrying out atmospheric impact studies and in the development of the used models\, in particular Lagrangian Particle Dispersion models. \nIn her free time\, Daniela enjoys reading books and travelling.
