Modelling laser beam absorption for powder-based sintering [PDF]

EPJ Web of Conferences
Additive manufacturing techniques like selective laser sintering face challenges such as residual stresses and warping. Understanding laser-powder interaction is crucial to addressing these issues.

3D mechanical characterization of single cells and small organisms using acoustic manipulation and force microscopy

Nature Communications, 2021
It is currently challenging to mechanically assess 3D specimens without manual handling. Here the authors combine a micro-force sensor and an acoustically controlled manipulation device to enable rotation of samples while assessing mechanical properties ...

A Novel Deep Learning Method for Automatic Recognition of Coseismic Landslides

Remote Sensing, 2023
Massive earthquakes generally trigger thousands of coseismic landslides. The automatic recognition of these numerous landslides has provided crucial support for post-earthquake emergency rescue, landslide risk mitigation, and city reconstruction.

Multi-scale Discrete Surfaces [PDF]

, 2002
In this article, we first propose a method to discretize a surface represented by a polyhedron. Then, we define a data structure used to work on such a discrete surface and that allows us to consider multi-scale discrete surfaces. Then, we explain how to perform easily and quickly boolean set operations on this data structure.

Multi-scale polarisation phenomena [PDF]

Light: Science & Applications, 2016
AbstractMulti-scale methods that separate different time or spatial scales are among the most powerful techniques in physics, especially in applications that study nonlinear systems with noise. When the time scales (noise and perturbation) are of the same order, the scales separation becomes impossible. Thus, the multi-scale approach has to be modified

Magnetically Guided Laser Surgery for the Treatment of Twin‐to‐Twin Transfusion Syndrome

Advanced Intelligent Systems, 2022
Twin‐to‐twin transfusion syndrome (TTTS) is a severe disorder that often leads to the death of monochorionic twin fetuses, if left untreated. Current prenatal interventions to treat the condition involve the use of rigid fetoscopes for targeted laser ...

Multi-scale modeling of gas-fluidized beds [PDF]

, 2006
Numerical models of gas-fluidized beds have become an important tool in the design and scale up of gas-solid chemical reactors. However, a single numerical model which includes the solid-solid and solid-fluid interaction in full detail is not feasible ...

Steady state rheology from homogeneous and locally averaged simple shear simulations

EPJ Web of Conferences, 2017
Granular materials and particulate matter are ubiquitous in our daily life and they display interesting bulk behaviors from static to dynamic, solid to fluid or gas like states, or even all these states together. To understand how the micro structure and

Multi-scale image harmonization [PDF]

ACM SIGGRAPH 2010 papers, 2010
Traditional image compositing techniques, such as alpha matting and gradient domain compositing, are used to create composites that have plausible boundaries. But when applied to images taken from different sources or shot under different conditions, these techniques can produce unrealistic results.

Multi-Scale attributed node embedding [PDF]

Journal of Complex Networks, 2021
Abstract We present network embedding algorithms that capture information about a node from the local distribution over node attributes around it, as observed over random walks following an approach similar to Skip-gram. Observations from neighbourhoods of different sizes are either pooled (AE) or encoded distinctly in a multi-scale ...
