Introduzione [a: Contratti pubblici e intelligenza artificiale]
No full textIl contributo introduce il volume inquadrato come raccolta di scritti nell'ambito della quale magistrati, studiosi e funzionari, affrontano in maniera esplicita e approfondita la questione del ruolo che l’intelligenza artificiale può (e deve) assumere nelle dinamiche dell’affidamento, della gestione e del controllo degli appalti pubblici.This contribution introduces the volume, which is framed as a collection of writings in which magistrates, scholars, and public officials explicitly and thoroughly address the question of the role that artificial intelligence can (and should) assume in the dynamics of awarding, managing, and controlling public procurement
From code to performance: Probabilistic seismic response of retrofitted precast RC buildings
Full text linkInadequate detailing in precast buildings designed under previous codes has proven to be a key factor in the seismic vulnerability of Italy's industrial heritage. Advances in structural assessment and refined hazard mapping have led to strategies now embedded in design guidelines, yet retrofitting existing buildings to ensure efficiency remains an open issue. This paper investigates the probabilistic seismic vulnerability of four single-story precast RC buildings constructed between the 1960s and 1990s in a high seismic hazard area according to the codes of the time. For each case, retrofit measures were designed following current standards and tailored solutions were proposed. Their effectiveness was assessed through advanced analyses at two performance levels, usability preventing damage and global collapse, using a probabilistic methodology that includes modal analysis, non-linear pushover, multi-stripe dynamic analysis, fragility curve derivation, and failure rate assessment
Il segreto dell’infanzia. L’esperienza di un tempo nuovo nelle pagine di Walter Benjamin = The secret of childhood. The experience of a new time in the writings of Walter Benjamin
Full text linkThe essay explores the world and experience of childhood as observed and described by Walter Benjamin in his so-called “mi-nor” articles and essays, which in fact shed light on his entire bo-dy of work, and particularly on his philosophy of history.
Benjamin approaches the world of childhood in its materiali-ty through picture books, toys, fairy tales, images, atmospheres, and memories. It is precisely in the subtle connections linking childhood, memories, and history that he seems to uncover traces of a secret kept by children: children's play expresses a creative force capable of interrupting continuity, subverting the establi-shed order, and liberating and renewing the world
From Surveying Techniques to a 3D GIS Geodatabase
No full textTopographic surveys of buildings are usually performed with a variety of instruments and techniques. Then, dedicated software packages provide 3D metric models that can be enriched with a series of descriptive information. The user can choose between three different options: Building Information Modelling (BIM), Historical Building Information Modelling (HBIM) and 3D GIS Geodatabases.
Particularly regarding cultural heritage buildings, information is extremely heterogeneous. Geographic Information System (GIS) software packages facilitate the creation of georeferenced 3D environments and geodatabases. This allows linking all the information to the referenced metric building; it is useful for its maintenance, restoration and management. The surrounding environment, to which it is closely connected, plays an important role. This paper describes how we built a GIS geodatabase of two 3D-modelled apses of a small church in the province of Bergamo. All the available information was gathered and linked in a 3D GIS

Photonics West 2018 Invited Talk
No full textWe investigate the application of integrated micro-combs in RF photonic systems and demonstrate a microwave photonic intensity differentiator based on a Kerr optical comb generated by a compact integrated micro-ring resonator. The on-chip Kerr optical comb is CMOS-compatible and contains a large number of comb lines, which can serve as a high-performance multi-wavelength source for the transversal filter, thus greatly reduce the cost, size, and complexity of the system. The operation principle is theoretically analyzed, and experimental demonstrations of fractional-, first-, second-, and third-order differentiation functions based on the principle are presented
A robust tube-based MPC approach for safer insulin dosing
No full textWe present a robust model predictive control (MPC) approach for safer insulin dosing in artificial
pancreas systems. The method applies estimation-informed constraint tightening to maintain safety
under disturbances and unmodeled dynamics. Safety margins, derived from estimator confidence, are
enforced as tube-based tightening on state and input constraints. A zone control objective targets a
glucose band with asymmetric weights that emphasize avoidance of low glucose. Simulation studies
show fewer low glucose events and lower violation risk than a nominal MPC baseline, with comparable
dosing effort. The contribution of this work is a robust zone MPC scheme that maps estimator
uncertainty into safety margins for insulin dosin
Scultura romanica allo specchio: la questione lombarda e l'Italia centrale
No full textThe paper critically reassesses the historiographical dominance of the Lombard
region in interpretations of Italian Romanesque sculpture. It argues that, from the
late 19th century onward, Lombardy was constructed as the central axis of national
narratives on Romanesque art, while the sculptural production of Central Italy was
marginalized or interpreted through Lombard models. Through an analysis rooted
in cartographic representations and scholarly narratives, the study traces the
ideological and nationalist foundations of this paradigm and its consolidation through
canonical art historians and local scholarship. Focusing on regions such as Umbria,
Marche, Abruzzo, and Molise, the work highlights the formal diversity and local
identities of Central Italian sculpture, advocating a polycentric and more nuanced
understanding of Romanesque sculpture in Italy and questioning the long-standing
primacy of Lombard art
Stewardship as a driver of digital business alignment in family firms: Are there performance consequences?
No full textStewardship can be a competitive resource that enhances collectivistic orientations and alignment within family firms. However, it is important to understand whether stewardship is beneficial in creating a shared vision between digital technology and business strategies. Although the existing literature offers limited insights into these relationships, advancing such knowledge is essential, as family firms encounter considerable challenges in implementing digital transformation, which in turn significantly affects their performance. Therefore, this study sheds light on how stewardship can work as a driver of digital business alignment, an information processing capacity aimed at the alignment of digital technology and business strategy, to enhance family firm performance, while also exploring the contingency role of family ownership. Theoretical hypotheses are tested using global survey data encompassing a sample of 2266 family firms from 70 countries. The main findings suggest a positive partial mediation, implying that stewardship family-oriented goals positively impact digital business alignment, leading to positive performance outcomes. Furthermore, family ownership weakens the positive relationship between stewardship family-oriented goals and digital business alignment. These findings have important implications for stewardship, information processing, and family firm research, providing valuable insights into the role of aligning digital and strategic interests, and managing family ownership in environments increasingly impacted by digital technologies
