Cyanoacetylene HC3N is a molecule of great astronomical importance and it has been observed in many interstellar environments. Its deuterated form DC3N has been detected in number of sources from external galaxies to Galactic interstellar clouds, star-forming regions and planetary atmospheres. All these detections relied on previous laboratory investigations, which however still lack some essential information concerning its infrared spectrum. In this project, high-resolution ro-vibrational spectra of DC3N have been recorded in two energy regions: 150 – 450 cm-1 and 1800 – 2800 cm-1. In the first window the ν7← GS, 2ν7 ← ν7, ν5 ← ν7, ν5+ν7 ← 2ν7, ν6+ν7 → 2v7, 4ν7 ← 2ν7 bands have been assigned, while in the second region the three stretching fundamental bands ν1, ν2, ν3 have been observed and analysed. The 150 – 450 cm-1 region spectra have been recorded at the AILES beamline at the SOLEIL synchrotron (France), the 1800 – 2800 cm-1 spectra at the Department of Industrial Chemistry “Toso Montanari” in Bologna. In total, 2299 transitions have been assigned. Such experimental transition, together with data previously recorded for DC3N, were included in a least-squares fitting procedure from which several spectroscopic parameters have been determined with high precision and accuracy. They include rotational, vibrational and resonance constants. The spectroscopic data of DC3N have been included in a line catalog for this molecule in order to assist future astronomical observations and data interpretation. A paper which includes this research work has been published (M. Melosso, L. Bizzocchi, A. Adamczyk, E. Cane, P. Caselli, L. Colzid, L. Dorea, B. M. Giulianob, J.-C. Guillemine, M-A.

Vaults are an architectural element which during construction history have been built with a great variety of different materials, shapes, and sizes. The shape of these structural elements was often dependent by the necessity to cover complex spaces, by the needed loading capacity, or by architectural aesthetics. Within this complex scenario masonry patterns generates also different effects on loading capacity, load percolation and stiffness of the structure. These effects were been extensively investigated, both with empirical observations and with modern numerical methods. While most of them focus on analyzing the load bearing capacity or the texture effect on vaulted structures, the aim of this analysis is to investigate on the effects of the variation of a single structural characteristic on the load percolation in the vault. Moreover, an additional purpose of the work is related to the coding of a parametrical model aiming at generating different masonry vaulted structures. Nevertheless, proposed script can generate different typology of vaulted structure basing on some structural characteristics, such as the span and the length to cover and the dimensions of the blocks.

L’uscita dalla pandemia, il conflitto russo-ucraino e la corsa ai bonus edilizia hanno provocato un generale aumento del prezzo dei materiali edili e delle opere provvisionali. I ponteggi hanno visto particolari rincari, per via del fatto che superbonus e bonus facciate ne richiedono un ampio utilizzo. Nel presente elaborato si è cercata una soluzione a tale criticità nelle direzioni che sta prendendo a livello internazionale il settore delle costruzioni, sulla strada della digitalizzazione e dell’applicazione di soluzioni informatiche in grado di ottimizzare i processi. Si è perciò creato un modello parametrico di ponteggio a telai prefabbricati che si adatti nel miglior modo possibile a ogni tipo di fabbricato. Nello specifico, è stato elaborato un algoritmo che, dati il sedime e l’altezza dell’edificio, generi in maniera automatica il modello tridimensionale del ponteggio, consentendo la visualizzazione immediata del suo sviluppo nello spazio del cantiere e l’estrapolazione di elaborati grafici quali pianta e prospetti. Nella presente dissertazione viene illustrato come è stato sviluppato tale algoritmo, utilizzando il software Revit e in particolare lo strumento di programmazione visiva Dynamo. Infine, poiché l’obiettivo è quello di individuare un algoritmo applicabile a qualsiasi edificio dato, il modello viene testato su un caso di studio particolare: la ristrutturazione di un fabbricato all’interno del complesso Cooperativa Sociale CIM.
