L1-Norm Redundant Delaunay Phase Unwrapping and Gradient Correction

This article deals with arrays of real numbers which have been reduced modulo 2h into theinterval [−h, h] where h > 0 is a positive real number. Such an array is said to be wrappedmodulo 2h. Often, the elements of these arrays correspond to…

Bridging Contrastive Learning and Domain Adaptation: Theoretical Perspective and Practical Application

This work studies the relationship between Contrastive Learning and Domain Adaptation from a theoretical perspective. The two standard contrastive losses, NT-Xent loss (Self-supervised) and Supervised Contrastive loss, are related to the Class-wise…

Ultrasound-induced dense granular flows: a two-time scale modeling

Understanding the mechanisms behind the remote triggering of landslides by seismic waves at micro-strain amplitude is essential for quantifying seismic hazards. Granular materials provide a relevant model system to investigate landslides within the…

An Experimental Study Of The Vortical Structures In Supersonic Steam Jet Impinged On To The Wall

This study presents an experimental investigation into the impingement of a supersonic steam jet onto a wall. Steam was injected through a supersonic nozzle at a varying total pressure of 1.5-3.0 bars, producing a supersonic steam jet at a pressure…

Iteratively Reweighted Least Squares for Phase Unwrapping

The 2D phase unwrapping problem seeks to recover a phase image from its observation modulo 2$\pi$, and is a crucial step in a variety of imaging applications. In particular, it is one of the most time-consuming steps in the interferometric synthetic…

Constrained Approximate Optimal Transport Maps

We investigate finding a map $g$ within a function class $G$ that minimises an Optimal Transport (OT) cost between a target measure $\nu$ and the image by $g$ of a source measure $\mu$. This is relevant when an OT map from $\mu$ to $\nu$ does not…
