Models for Quadratic Algebras Associated with Second Order Superintegrable Systems in 2D [PDF]

open access: yes, 2008
There are 13 equivalence classes of 2D second order quantum and classical superintegrable systems with nontrivial potential, each associated with a quadratic algebra of hidden symmetries.

Gait Analysis of Pak Biawak: A Necrobot Lizard Built using the Skeleton of an Asian Water Monitor (Varanus Salvator)

open access: yesAdvanced Robotics Research, EarlyView.
Pak Biawak, a necrobot, embodies an unusual fusion of biology and robotics. Designed to repurpose natural structures after death, it challenges conventional boundaries between nature and engineering. Its movements are precise yet unsettling, raising questions about sustainability, ethics, and the untapped potential of biointegrated machines.

A Soft Robotic Fish With a Dielectric Elastomer Actuator Body and Negative Stiffness Spine

open access: yesAdvanced Robotics Research, EarlyView.
This work introduces a bio‐mimetic soft robotic fish driven by fiber‐reinforced dielectric elastomer actuators integrated as its body. By prestretching this active skin against a flexible spine, a negative stiffness system is created, enabling large‐amplitude bending.

Modular, Textile‐Based Soft Robotic Grippers for Agricultural Produce Handling

open access: yesAdvanced Robotics Research, EarlyView.
This article introduces textile‐based pneumatic grippers that transform simple textiles into robust bending actuators. Detailed experiments uncover how cut geometry and fabric selection shape performance. Successful handling of fragile agricultural items showcases the potential of textile robotics for safe, scalable automation in food processing and ...

Nearly Ternary Quadratic Higher Derivations on Non-Archimedean Ternary Banach Algebras: A Fixed Point Approach

open access: yesAbstract and Applied Analysis, 2011
We investigate the stability and superstability of ternary quadratic higher derivations in non-Archimedean ternary algebras by using a version of fixed point theorem via quadratic functional equation.

General Solutions of Two Quadratic Functional Equations of Pexider Type on Orthogonal Vectors

open access: yesAbstract and Applied Analysis, 2012
Based on the studies on the Hyers-Ulam stability and the orthogonal stability of some Pexider-quadratic functional equations, in this paper we find the general solutions of two quadratic functional equations of Pexider type. Both equations are studied in

ON THE SOLUTION AND STABILITY OF THE QUADRATIC TYPE FUNCTIONAL EQUATIONS [PDF]

open access: yesCommunications of the Korean Mathematical Society, 2004
Summary: We prove the solution and stability of the quadratic type functional equations with two variables \[ 4f(\frac{x-2y}{2})+f(x)+2f(y)=8f(\frac{x-y}{2})+f(2y) \] and \[ f(x-2y) + f(x)+2f(y)=2f(x-y)+f(2y). \]

Nonreciprocal Swarmalators With Reconfigurable and Controllable Formations for Robot Collectives

open access: yesAdvanced Robotics Research, EarlyView.
Nonreciprocal swarmalator interactions are enabled through control barrier functions to transform self‐organizing robot collectives into reconfigurable, constraint‐aware systems. Complex two‐ and three‐dimensional shapes, continuous morphing, obstacle‐aware navigation, collective splitting, and object transport emerge from modulating agent‐level ...

Some generalization of the quadratic and Wilson’s functional equation [PDF]

open access: yesAequationes mathematicae, 2013
Let \(X\) be a linear space over the field \(\mathbb{K} \in \{\mathbb{R}, \mathbb{C}\}\), \((G,+)\) be an abelian group, let \(K\) be a finite abelian subgroup of the automorphism group of \(G\) and let \(L:= card K\). All solutions \(f, g, h: G \to X\) and \(\varphi: G \to \mathbb{K}\) of the functional equation \[ \sum_{\lambda \in K} f(x + \lambda y)
