Dynamic Wave Trains: A Procedural Approach to Spatially Varying Ocean Synthesis
Computer Graphics Forum, EarlyView.In this paper, we present a high performance procedural model capable of synthesizing and rendering a virtually infinite ocean. Our method exhibits spatial variations as the orientations, speed and choppiness of the waves is parametrized for each frequencies and each point in space. The provided visual abstract exhibits a sunset rendering of a large 40

Beyond Spherical Harmonics: Rethinking Appearance Models for Radiance Reconstruction
Computer Graphics Forum, EarlyView.Abstract View‐dependent appearance modeling remains a challenging problem in novel‐view synthesis and reconstruction. Accurately representing complex angular effects often requires substantial memory and computational resources. For new learning‐based methods, a common approach is to rely on Spherical Harmonics (SH).

Augmented Lagrangian method for a total variation-based model for demodulating phase discontinuities
Journal of Algorithms & Computational Technology, 2020 In this work, we reformulate the method presented in App. Opt. 53:2297 (2014) as a constrained minimization problem using the augmented Lagrangian method.

Dam Management in the Era of Climate Change
Mathematical Finance, EarlyView.ABSTRACT Climate change has a dramatic impact, particularly by concentrating rainfall into a few short periods, interspersed with long dry spells. In this context, the role of dams is crucial. We consider the optimal control of a dam, where the water level must neither exceed a designated safety threshold nor fall below a minimum level to ensure ...

A new family of models with generalized orientation in data envelopment analysis
International Transactions in Operational Research, Volume 34, Issue 1, Page 580-605, January 2027.Abstract In the framework of data envelopment analysis, we review directional models and show that they are inadequate when inputs and outputs are improved simultaneously under constant returns to scale. Conversely, we introduce a new family of quadratically constrained models with generalized orientation and demonstrate that these models overcome this
