A note on the expression of modulus of convexity

open access: yesAnnals of Functional Analysis, 2012
‎It is well known that different kinds of expressions of modulus of‎ ‎convexity are essentially based on two geometrical propositions‎. ‎For‎ ‎one of the propositions we first present a new proof by the‎ ‎Hahn-Banach theorem and intermediate value theorem‎, ‎then give some‎ ‎corollaries to it which lead to some new expressions of modulus of‎ ‎convexity‎

Hierarchical Multi‐Material Architectures With Gradient Design for Dynamic‐Range Flexible Tactile Sensing

open access: yesAdvanced Materials Technologies, EarlyView.
Hierarchical multi‐material TPMS lattices are engineered as flexible tactile sensors by combining soft and stiff elastomeric layers with a conformal conductive coating. The bilayer architecture delivers sensitivity at low pressures while maintaining a broad detectable range under large loads, enabling reliable pressure and vibration monitoring for ...

Origami‐Inspired Structural Design for Aquatic‐Terrestrial Amphibious Robots

open access: yesAdvanced Robotics Research, EarlyView.
This work presents a lightweight amphibious origami robot actuated by a single shape memory alloy wire. A rigid foldable origami structure with displacement amplification enables efficient terrestrial crawling and aquatic swimming. The addition of fan‐shaped units allows controllable turning in both environments.

Continuity of modulus of noncompact convexity for minimalizable measures of noncompactness

open access: yes, 2015
We consider the modulus of noncompact convexity $ _{X, }(\varepsilon)$ associated with the minimalizable measure of noncompactness $ $. We present some properties of this modulus, while the main result of this paper is showing that $ _{X, }(\varepsilon)$ is a subhomogenous and continuous function on $[0, (\bar{B}_X))$ for an arbitrary ...

Solid Harmonic Wavelet Bispectrum for Image Analysis

open access: yesAdvanced Science, EarlyView.
The Solid Harmonic Wavelet Bispectrum (SHWB), a rotation‐ and translation‐invariant descriptor that captures higher‐order (phase) correlations in signals, is introduced. Combining wavelet scattering, bispectral analysis, and group theory, SHWB achieves interpretable, data‐efficient representations and demonstrates competitive performance across texture,

Modulus of supporting convexity and supporting smoothness

open access: yes, 2015
We introduce the moduli of the supporting convexity and the supporting smoothness of a Banach space, which characterize the deviation of the unit sphere from an arbitrary supporting hyperplane. We show that the modulus of supporting smoothness, the Bana{ } modulus, and the modulus of smoothness are all equivalent at zero, the modulus of supporting ...
