Reliability-Focused Design, Management, and Maintenance of Water Distribution Networks

Access to clean water is vital for hygiene and public health and is critical for social and economic activity of urban life. Water distribution networks (WDNs) bring water from sources and treatment facilities to consumers via interconnected systems of pipes and mechanical components. The increasing urbanization and continuous changes in demand patterns and land use result in incremental modifications, expansions, and rehabilitation actions that gradually transform the network. At the same t...

Design of Circuits for Analog in-Memory Computing

The rapid surge of Artificial Intelligence (AI) has highlighted the need for computing architectures capable of performing low-energy computations on large data sets. The widely used von Neumann architecture has proven inadequate to meet the computational demands of modern Deep Neural Networks (DNNs), mainly due to the physical separation between processing and memory units, commonly referred to as the ``memory wall'', which constitutes a severe communication bottleneck. In recent years, seve...

“Who owns the past?” Ownership of culture and contested heritage

Il presente lavoro di ricerca si colloca nel campo dei Museum Studies e dei Critical Heritage Studies. Uno dei principali obbiettivi di questa tesi è stato indagare il modo in cui il patrimonio archeologico può diventare terreno di scontro ideologico, politico, culturale. Inserendosi pienamente nel dibattito sulla decolonizzazione del patrimonio culturale, il progetto si concentra sul ruolo dei musei occidentali nel custodire e interpretare il passato, con un focus sull’Egitto antico. La tesi...

External Exposome of Italian adults with Multiple Sclerosis focusing on nutrition-related inflammation: results from the cross-sectional EXPOSITION study

Background: The cause of multiple sclerosis (MS) is unknown and likely multifactorial, including genetic, environmental and lifestyle factors. Some dietary patterns have been studied in relation to MS, however the data are scarce, especially about the role of nutrients, dietary inflammation and body composition. Aims: This thesis aims to fill these gaps by assessing nutrition and lifestyle habits in people with MS, examining sex-specific differences and their associations with phase angle and...

Development and Characterization of a System in Package Short Circuit Protection for SiC Power MOSFET

With respect to silicon isolated-gate bipolar transistors (IGBT), silicon Carbide MOSFETs offer better performance in terms of maximum voltage and current. For similar blocking voltage and current ratings, they show higher current density, higher power density, lower conduction losses and better high temperature tolerance. On the other hand, due to their smaller active area, SiC MOSFETs show a lower thermal dissipation capability and consequently, a lower short circuit withstand time. Typical...

Design of a High Efficiency Inverting Buck-Boost Converter for OLED Displays

This thesis addresses the design of high-efficiency inverting DC–DC converters for AMOLED display applications in mobile devices. AMOLED panels require negative bias voltages whose magnitude varies with operating conditions and luminance, imposing stringent constraints on efficiency, silicon area, and passive component count in power management integrated circuits. The work presents a comprehensive analysis of different converter topologies, including inductive, switched-capacitor, and hybrid...

Progettazione di amplificatori di potenza a livello di watt e alta linearità in tecnologia SiGe BiCMOS per applicazioni 6G nella banda FR3

Questa dissertazione affronta la progettazione e la caratterizzazione di amplificatori di potenza basati su transistor bipolari a eterogiunzione (HBT) in tecnologia BiCMOS al silicio-germanio (SiGe), destinati alla banda di frequenze FR3 (7–24 GHz) per i sistemi di comunicazione wireless 5G-Advanced e 6G. Rispetto alla banda sub-6 GHz, ottenere potenze di uscita dell’ordine del watt con elevato guadagno, efficienza e linearità nella banda FR3 risulta più impegnativo a causa delle limitazioni...

Analysis and development of novel supply and driving features for high efficiency power switches
