Design of a Direct numerical Simulation of flow and heat transfer in a T-junction

Several investigations have been undertaken to study the velocity and temperature fields associated with the thermal mixing between fluids, and resulting thermal striping in a T-junction. However, the available experimental databases are not sufficient to describe the involved physics in adequate detail, and, due to experimental limitations,...

Revealing the nanogeometry of WS2 nanoflowersby polarization-resolved Raman spectroscopy

Recent studies of transition metal dichalcogenides (TMDs) have revealed exciting optical properties, such as stable excitons and chiral light–matter interactions. Chemical vapor deposition techniques provide a platform for the fabrication of nanostructures with diverse geometries, ranging from horizontal flakes to flower-like structures. Raman...

The interaction of light with WS2 nanostructures

In this thesis we describe three results of the interaction between WS2 and light: photoluminescence, the formation of exciton-polaritons and Raman scattering. The chirality of the photoluminescence interaction between WS2 and light opens the way for applictions in nanophotonics and specifically valleytronics, the field of interacting with and...

Morphology-induced spectral modification of self-assembled WS₂pyramids

Due to their intriguing optical properties, including stable and chiral excitons, two-dimensional transition metal dichalcogenides (2D-TMDs) hold the promise of applications in nanophotonics. Chemical vapor deposition (CVD) techniques offer a platform to fabricate and design nanostructures with diverse geometries. However, the more exotic the...

Nonlinear Optical Response of a WS₂Monolayer at Room Temperature upon Multicolor Laser Excitation

Currently, the nonlinear optical properties of 2D materials are attracting the attention of an ever-increasing number of research groups due to their large potential for applications in a broad range of scientific disciplines. Here, we investigate the interplay between nonlinear photoluminescence (PL) and several degenerate and nondegenerate...

Nanoscale Optical Addressing of Valley Pseudospins through Transverse Optical Spin

Valley pseudospin has emerged as a good quantum number to encode information, analogous to spin in spintronics. Two-dimensional transition metal dichalcogenides (2D TMDCs) recently attracted enormous attention for their easy access to the valley pseudospin through valley-dependent optical transitions. Different ways have been reported to read...

Social multicritieria evaluation of alternative solutions for coastal erosion: The case of the Lido of Sète

This report describes a study case performed in the frame of the component 3 “Valuating shoreline” within the Messina project, Interreg III-C West. The aim of the Component 3 is to review concrete examples of economic analysis methodologies applied to shoreline management policy inside and outside Europe. This report presents the application of...

Low-level image processing architectures: Compared for some non-linear recursive neighbourhood operations

Impact of ERS-1 observations on wave forecasting in the North Sea

A rather large number of conventional observations is available for the North Sea. Yet a comparison with the coverage of ERS-1 shows that its data will be a valuable addition to the existing data, especially in the north. The wave forecasting methods in use for swell forecasting in the southern North Sea suffer from a lack of data from the...

Description of the KNMI Operational Wave Forecast Model GONO

The purpose of this report is to give a description of the GONO computercode, which is operational at KNMI for many years now. The program was developed by J.W. Sanders, and its deep water version is based on a Norwegian wave prediction model. built by C. Haug in the sixties. Shallow water effects are however important in the southern part of...
