r2SCAN-3c: A "Swiss army knife" composite electronic-structure method.

Journal of Chemical Physics, 2021
The recently proposed r2SCAN meta-generalized-gradient approximation (mGGA) of Furness and co-workers is used to construct an efficient composite electronic-structure method termed r2SCAN-3c.

Characterization of errors in compositing panoramic images

Proceedings of IEEE Computer Society Conference on Computer Vision and Pattern Recognition, 1999
A panoramic image has a 360° horizontal field of view, and it can provide the viewer the impression of being immersed in the scene. A panorama is created by first taking a sequence of images while rotating the camera about a vertical axis. These images are then projected onto a cylindrical surface before being seamlessly composited. The cross-sectional

Mean Squared Error, Deconstructed

Journal of Advances in Modeling Earth Systems, 2021
As science becomes increasingly cross‐disciplinary and scientific models become increasingly cross‐coupled, standardized practices of model evaluation are more important than ever.

Error bounds for direct and composite cubature formulae—I

Calcolo, 1975
In this part II, narrow cubature error bounds given by Lether are used and made suitable for comparing direct and composite integration techniques for two-dimensional Gauss-Legendre formulae. The results we obtain support the conclusion that in many cases composite formulae turn out to be preferable in comparison with direct ones.

CPR-CLIP: Multimodal Pre-Training for Composite Error Recognition in CPR Training

IEEE Signal Processing Letters
The expensive cost of the medical skill training paradigm hinders the development of medical education, which has attracted widespread attention in the intelligent signal processing community. To address the issue of composite error action recognition in
