Monitoring Lakes in Mountains with Sentinel-1 SAR Imagery

Lakes are crucial markers of climate fluctuations, yet identifying water bodies in mountainous regions remains a persistent challenge for satellite remote sensing due to terrain-induced obstacles and dynamic surface conditions of ice and snow. We present a novel approach based so...

HySoP: Hybrid Simulation with Particles

Official release of the code.

Localization coefficients of functions with applications in partial differential equations

Abstract We identify shortcomings in two popular measures of localization of functions: the $$L^p\text {-}L^q$$ L p - L q participation ratio and the mass concentration comparison. We then introduce a novel localization measure for functions on bounded subsets of $$\varvec{R}^d$$...

Advancing conflict research and response through satellite-derived data

Abstract With armed conflicts at a historic high and attacks on civilians rising 1 , understanding the evolving nature of conflict is a critical research priority. The current paradigm in conflict research relies heavily on text-based data, using fatalities as the primary—and oft...

Active learning strategies for the estimation of a feasible set defined from a vector output black-box simulator

Many industrial problems require the use of black-box numerical simulators, for which it is essential to determine the set of so-called feasible input parameters. A set of parameters is feasible if the output of the code on these parameters satisfies given constraints, for exampl...
