Improvement of Turbine Inertia Compensation in Wind Turbine Emulators using Kalman Filter [PDF]
International Journal of Research and Technology in Electrical Industry, 2023 In this paper, a 3.1kW DC motor is used to simulate the static and dynamic behavior of a horizontal axis wind turbine. The effect of the difference between the wind turbine's inertia and DC motor on the dynamic behavior of the system, torque oscillation ...

Soft bilateral filtering volumetric shadows using cube shadow maps [PDF]
PLOS ONE, 2017 Les ombres volumétriques augmentent souvent le réalisme des scènes rendues en infographie. Les techniques d'ombres volumétriques typiques ne fournissent pas un effet de transition en douceur en temps réel avec une conservation sur la netteté des limites.

Distinguishing shadows from surface boundaries using local achromatic cues.
PLoS Computational Biology, 2022 In order to accurately parse the visual scene into distinct surfaces, it is essential to determine whether a local luminance edge is caused by a boundary between two surfaces or a shadow cast across a single surface.

Video SAR Moving Target Tracking Using Joint Kernelized Correlation Filter
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022 Video synthetic aperture radar (ViSAR) has been found very useful for the surveillance of ground moving targets. The target energy can be utilized for ground moving target tracking, while the dynamic shadows of moving targets enable an alternative ...

Low-Pass Filtered Volumetric Shadows
IEEE Transactions on Visualization and Computer Graphics, 2014 We present a novel and efficient method to compute volumetric soft shadows for interactive direct volume visualization to improve the perception of spatial depth. By direct control of the softness of volumetric shadows, disturbing visual patterns due to hard shadows can be avoided and users can adapt the illumination to their personal and application ...
