Robustness via Curvature Regularization, and Vice Versa [PDF]

open access: yesComputer Vision and Pattern Recognition, 2018
State-of-the-art classifiers have been shown to be largely vulnerable to adversarial perturbations. One of the most effective strategies to improve robustness is adversarial training.

Influence of Surface Curvature on Coanda Effect for Vertical Jet Impacting Horizontal Cylinder [PDF]

open access: yesJournal of Applied Fluid Mechanics, 2023
The Coanda effect is a tendency of flowing fluid to follow the solid surface rather than to separate under the inertial effect. This paper presents the effects of surface curvature on the Coanda angle and jet deflection for a vertical jet impacting a ...

Hamilton type gradient estimates for a general type of nonlinear parabolic equations on Riemannian manifolds

open access: yesAIMS Mathematics, 2021
$ (\Delta_{V}-q(x, t)-\partial_{t})u(x, t) = A(u(x, t)) $ on complete Riemannian manifold (with fixed metric). When $ V = 0 $ and the metric evolves under the geometric flow, we also derive some Hamilton type gradient estimates.

Tape surface characterization and classification in automated tape placement processability: Modeling and numerical analysis

open access: yesAIMS Materials Science, 2018
Many composite forming processes are based on the consolidation of preimpregnated preforms of different types, e.g., sheets, tapes, .... Composite plies are put in contact using different technologies and consolidation is performed by supplying heat and ...

Global and local contributions to surface curva- ture of healthy corneas

open access: yesAfrican Vision and Eye Health, 2012
This paper demonstrates for several healthy eyes the application of a simple model to understanding local and global contributions to short-term variation in anterior and posterior corneal curvature.

Influence of the Size and Curvedness of Neural Projections on the Orientationally Averaged Diffusion MR Signal

open access: yesFrontiers in Physics, 2018
Neuronal and glial projections can be envisioned to be tubes of infinitesimal diameter as far as diffusion magnetic resonance (MR) measurements via clinical scanners are concerned.

A Model of the Moment Curvature Relation for RC Beams Strengthened with Prestressed CFRP Laminates

open access: yesArchives of Civil Engineering, 2019
The paper presents an analysis of the behaviour of bent reinforced concrete beams strengthened with CFRP laminates fixed with adhesive before and after unloading, and more importantly, an analysis of the work of reinforced concrete beams strengthened ...

New Gauss-Bonnet Black Holes with Curvature-Induced Scalarization in Extended Scalar-Tensor Theories. [PDF]

open access: yesPhysical Review Letters, 2017
In the present Letter, we consider a class of extended scalar-tensor-Gauss-Bonnet (ESTGB) theories for which the scalar degree of freedom is excited only in the extreme curvature regime.

Curvature tension: Evidence for a closed universe [PDF]

open access: yes, 2019
The curvature parameter tension between Planck 2018, cosmic microwave background lensing, and baryon acoustic oscillation data is measured using the suspiciousness statistic to be 2.5 to 3$\sigma$.

Preliminary Study on the Performance Evaluation of a Light Shelf Based on Reflector Curvature

open access: yesEnergies, 2019
The consumption of lighting energy in buildings continues to rise, and many studies are being conducted to address this problem. As part of such initiatives, research is being performed on light shelves, which are natural lighting systems.
