Description of Euler bricks using Fibonacci's identity [PDF]

open access: yes, 2013
We show how the Fibonacci's identity is used to obtain Euler bricks. Also,we put forward the relation between Fibonacci's identity and Euler's formula, which provides the description of Euler's bricks with noninteger spatial diagonal.

A High‐Precision and Robust Geometric Relationships‐Inspired Neural Network for the Inverse Kinematic Modeling of the Tendon‐Actuated Continuum Manipulator

open access: yesAdvanced Intelligent Systems, EarlyView.
An online learning control framework with a data cache pool based on a constant‐curvature model inspired neural network (CCMINN) model to obtain the inverse kinematics model of tendon‐actuated continuum manipulators is proposed. Combining the fast‐converging CCMINN with an online learning control framework enables high‐precision and highly robust ...

Bioinspired Fully On‐Chip Learning Implemented on Memristive Neural Networks

open access: yesAdvanced Intelligent Systems, EarlyView.
This work proposes a memristive neural network based on van der Waals ferroelectric memristors and contrastive Hebbian learning, enabling fully on‐chip learning. The system achieves over 98% accuracy in pattern recognition with low power consumption (0.321 nJ/image) and high robustness, paving the way for efficient, bioinspired neuromorphic computing ...

Real‐Time Control of a Humanoid Robot for Whole‐Body Tactile Interaction

open access: yesAdvanced Intelligent Systems, EarlyView.
Inspired by human tactile interaction, this work integrates large‐area artificial skin feedback (force and proximity) into real‐time quadratic programming control for humanoids. This enables robots to leverage distributed sensing to manage forces, safely move around unknown and dynamic obstacles, and robustly handle objects with uncertain geometry ...

Signal Amplification in Highly Ordered Networks Is Driven by Geometry

open access: yesCells, 2022
Here, we hypothesize that, in biological systems such as cell surface receptors that relay external signals, clustering leads to substantial improvements in signaling efficiency.

On Some Novel Results about Split-Complex Numbers, the Diagonalization Problem, and Applications to Public Key Asymmetric Cryptography

open access: yesJournal of Mathematics, 2023
In this paper, we present some of the foundational concepts of split-complex number theory such as split-complex divison, gcd, and congruencies. Also, we prove that Euler’s theorem is still true in the case of split-complex integers, and we use this ...

Two-point formulae of Euler type [PDF]

open access: yesThe ANZIAM Journal, 2002
AbstractAn analysis is made of quadratureviatwo-point formulae when the integrand is Lipschitz or of bounded variation. The error estimates are shown to be as good as those found in recent studies using Simpson (three-point) formulae.
