Abstract
This thesis documents the progressive enhancement of the metrological performance of the Italian primary
standard for absorbed dose to water, realized through a structured program of experimental investiga-
tions. The work was carried out at National Institute of Ionizing Radiation Metrology (ENEA INMRI),
and is centered on a graphite calorimeter operating within a water phantom. The measurements re-
ported for this investigation took place in ENEA Casaccia Research Center and a...
Carbon-based nanomaterials, such as graphene, exhibit exceptional electrical, thermal, and mechanical properties, making them highly attractive for technological applications.
However, the fabrication of pure and reproducible nanomaterials suitable for large-scale production remains complex and expensive. For this reason, increasing attention is being devoted to graphene nanoplatelet GNP-based nanocomposites, which preserve many of graphene’s functional advantages while offering improved rep...
Integrating detailed geological models into civil and environmental engineering projects is fundamental for an informed infrastructure design and an accurate seismic risk assessment, particularly in complex geologic, tectonic and hydrogeological settings. This work illustrates the methodological approaches and practical applications for developing a geological model of the Cassino Plain, an intermontane basin of central Italy characterised by a significant seismic hazard and complex hydrogeol...
Estimating morphological change in braided gravel bed rivers is important to determine the geometry of the active part of the braidplain, i.e. the width of the area where bed material is transported and the number of active branches during a certain time interval. Repeated surveys and photogrammetry have been used to measure morphological change with different spatial and temporal resolution but characterizing the geometry of braided rivers remains a problem. Increased satellite coverage an...
Future wireless systems must deliver higher data rates and reliability while
meeting strict power consumption limits and hardware costs. In recent years,
researchers have begun using Reconfigurable Intelligent Surfaces (RIS)
and Reconfigurable Holographic Surfaces (RHS) to control the way signals
move through space, relying on dense panels made of simple reflective
units that require little power. This thesis investigates the design, modelling,
and optimization of such metasurface-aided...
This doctoral thesis investigates the effects of physical exercise and combined motor–cognitive interventions on motor, neuromuscular, and neuroplastic outcomes in individuals with Parkinson’s disease (PD), adopting a multi-level and mechanism-informed perspective. The work integrates evidence from systematic reviews, an umbrella review, and an experimental study to examine how exercise characteristics and task demands influence functional performance and underlying neural mechanisms in PD.

Breast cancer imaging is central to early detection, yet current screening and diagnostic modalities remain limited by breast density, interpretive variability, and suboptimal specificity. This thesis investigates how deep learning can enhance breast cancer detection and diagnosis across mammography, digital breast tomosynthesis, and breast magnetic resonance imaging. Novel architectures are proposed to improve the detection of early radiographic indicators such as microcalcifications and to ...
The replacement of fossil energy sources with renewable ones has become
an even more pressing necessity, in a context in which the security
of gas supplies, the foundation of the Italian economic system, is jeopardized.
In this context, the electricity dispatching reform launched in
Italy with the approval of the TIDE is inserted; an all-encompassing
document, in force from 1 January 2025 with a gradual implementation
timetable, it has the aim of modifying the structure of the electrici...
The advent of the new concept of mobility, understood as sustainable and intelligent, has led to the growth and development of new forms of transport, especially in micro-mobility. Cyclists, scooter drivers, and pedestrians are becoming predominant categories within contemporary urban travel. However, if on the one hand, the evolution of the concept of urban transport certainly leads to environmental benefits such as the reduction of pollution, congestion, and so on, on the other hand, it bri...
This research focuses on the concept of dynamic alterity, that is, the fluidity of marginal identities in Shakespearean texts. It explores how outcast characters are defined and how they interact with the social and cultural norms of their time. The aim is to understand how Shakespeare represents, interrogates, and at times subverts the dynamics of power and identity in the Elizabethan and Jacobean eras, using marginal figures as critical instruments to reflect on the social and political ten...
