Bifurcation of positive solutions for the one-dimensional (p,q)-Laplace equation

open access: yesElectronic Journal of Differential Equations, 2017
In this article, we study the bifurcation of positive solutions for the one-dimensional (p,q)-Laplace equation under Dirichlet boundary conditions. We investigate the shape of the bifurcation diagram and prove that there exist five different types of

Control-based continuation for investigating nonlinear experiments [PDF]

open access: yes, 2010
This paper presents a systematic experimental study of two one-degree-of-freedom nonlinear devices using the newly introduced control-based continuation method by Sieber and Krauskopf [Nonlinear Dynamics 2008].

Emergent Spinning and Orbital Motion in Clustered Wind‐Assisted Flyers

open access: yesAdvanced Science, EarlyView.
Inspired by natural snowflake geometries, paper‐cut flyers exhibit geometry‐defined spinning and orbital motions during cluster formation in a wind tunnel. Collective flights of multiple paperflakes reveal dynamic clustering, fragmentation, and continuously evolving spin behaviors.

Bifurcation diagram for the Rössler attractor

open access: yes, 2013
The Rössler attractor is represented by the following set of ODEs: dx/dt=-(y+x); dy/dt=x+ay; dz/dt=b+xz-cz. The Demonstration plots the bifurcation diagram, where c is the bifurcation parameter, for values of parameters a and b set by the user.

From Flow to Function: Using Different Static Mixers to Fabricate Microarchitected Materials Via Chaotic Printing

open access: yesAdvanced Science, EarlyView.
Complex microarchitectures emerge from simple flow‐driven transformations as static mixers iteratively reorient and split material domains. Coupled with diverse deposition strategies, chaotic printing provides an accessible platform for fabricating architected materials that support biologically and chemically relevant processes. ABSTRACT Nature builds

From Folding Mechanics to Robotic Function: A Unified Modeling Framework for Compliant Origami

open access: yesAdvanced Science, EarlyView.
A geometry‐consistent DDG framework captures compliant origami deformation from rigid‐like folding to soft panel bending. By tuning crease and panel stiffness, bistable snap‐through responses transform into smooth monostable deformation, enabling programmable stability and robot‐scale locomotion.

Friction dynamics analysis of crossed beveloid gear with considering tooth surface topography

open access: yesAdvances in Mechanical Engineering
The contact surfaces of beveloid gears have different topography features due to different machining methods, manufacturing accuracies, and surface wear, and they are not always smooth.
