Excitonic devices with van der Waals heterostructures: valleytronics meets twistronics

Andras Kis, Ahmet Avsar, Alberto Ciarrocchi, Fedele Tagarelli

2D semiconducting transition metal dichalcogenides comprise an emerging class of materials with distinct properties, including large exciton binding energies that reach hundreds of millielectronvolts and valley-contrasting physics. Thanks to the van der Wa ...

Adaptive Laser Welding Control: A Reinforcement Learning Approach

Giulio Masinelli, Silvio Zanoli

Despite extensive research efforts in the field of laser welding, the imperfect repeatability of the weld quality still represents an open topic. Indeed, the inherent complexity of the underlying physical phenomena prevents the implementation of an effecti ...

Properties of convex optimal power flow model based on power loss relaxation

Mario Paolone, Zhao Yuan

We derive the branch ampacity constraint associated to power losses for the convex optimal power flow (OPF) model based on the branch flow formulation. The branch ampacity constraint derivation is motivated by the physical interpretation of the transmissio ...

Advanced models for stress evaluation and safety assessment in steel-lined pressure tunnels

Anton Schleiss, Pedro Filipe De Almeida Manso, Alexandre Jean Pachoud

An accurate estimation of the stress in a steel liner is required for the design of steel-lined pressure shafts, both with regard to safety assessment of ageing steel-lined waterways of hydropower plants built in the 20th century, and for new projects whic ...

Improved analytical solutions for the response of underground excavations in rock masses satisfying the generalized Hoek-Brown failure criterion

Vincent Labiouse

Analytical solutions for tunnel design are widely used in practical engineering, as they allow a quick analysis of design issues such as estimation of support requirement. In recent years, several papers analyzing the behavior of rock masses that obey the ...

Experimental assessment of riverbed sediment reinforcement by vegetation roots

Paolo Perona

Vegetation roots are known to increase soil stability on hillslopes, crops and river banks, thus reducing slide hazards, surface erosion and general processes affecting lateral channel migration. Many studies have tackled this classical engineering problem ...

Exploring G-Protein Coupled Receptor Activation with Multiscale Molecular Simulations

Stefano Vanni

This thesis is devoted to the study of the activation mechanism of G-protein coupled receptors (GPCRs), one of the largest and most diverse protein families in mammalian genomes, by means of different computer-based simulation techniques. Using force field ...

Constitutive modelling of unsaturated soils with hydro-geomechanical couplings

Mathieu Nuth

Even though the saturation in water of most natural and engineered soils is partial, constitutive models in geotechnical engineering have long made the assumption of complete saturation. The increasing knowledge of the rheological behaviour of unsaturated ...

Alexandre Sarrasin (1895-1976) et l'esthétique de l'ingénieur

Philippe Mivelaz

Alexandre Sarrasin (1895-1976) studied at Zürich Federal Swiss Institute of Technology (ETH) from 1913 to 1918. Despite First World War's conflicts surrounding the neutral Switzerland, the intellectual climate inside ETH was cosmopolitan and liberal. As un ...
