Dynamics of Bubble Plumes Produced by Breaking Waves

Bubble plumes play a significant role in the air-sea interface by influencing processes such as air-sea gas exchange, aerosol production, modulation of oceanic carbon and nutrient cycles, and the vertical structure of the upper ocean. Using acoustic…

Pair-dependent representations for Same-View Vehicle recognition

Deep metric learning approaches for object instance recognition struggle with generalization. To infer if two images are of the same instance, a representation is computed for each image, independently of the other. This is insufficient for reliably…

Numerical study of the Breaking of Short-Crested Waves : Breaking Onset, Energy Dissipation and Superharmonic Instability

Wave breaking plays a crucial role in energy dissipation and turbulent mixing at the ocean surface. Accurate predictions require robust breaking criteria and dissipation models. While most studies focus on two-dimensional systems, this thesis…

Numerical modeling accidental release of cryogenic liquid : application to liquid hydrogen (LH2) risk assessment

In the face of energy shortages and increasing pollution, many countries are developing policies to replace fossil fuels with clean alternative energy sources. Storage and transportation are crucial in the hydrogen sector. Compression and…

OneBatchPAM: A Fast and Frugal K-Medoids Algorithm

This paper proposes a novel k-medoids approximation algorithm to handle large-scale datasets with reasonable computational time and memory complexity. We develop a local-search algorithm that iteratively improves the medoid selection based on the…

CONFORMAL APPROACH TO GAUSSIAN PROCESS SURROGATE EVALUATION WITH COVERAGE GUARANTEES

Gaussian processes (GPs) are a Bayesian machine learning (ML) approach widely used to construct surrogate models for the uncertainty quantification (UQ) of computer simulation codes in industrial applications. It provides both a mean predictor and…

Progress and trends in liquid hydrogen release

Liquid hydrogen (LH2) is a promising method for large-scale, long-distance storage and transportation of green energy. However, LH2 leaks pose significant safety risks, such as fire and explosion, due to the rapid formation of gaseous hydrogen…

Two-timepoint assays of neural responses increase the sensitivity and specificity of single-cell whole-brain activity screens

Current approaches for surveying whole brains for neurons activated during a particular state typically rely on immediate early gene (IEG) expression. However, IEG expression is variable across subjects and brain areas, demanding large sample sizes…
