On existence of solutions of degenerate wave equations with nonlinear damping terms

open access: yes, 1998
Summary: We consider the existence and asymptotic behavior of solutions of the following problem: \[ u_{tt}- (\|\nabla u\|^2_2+ \|\nabla v\|^2_2)^\gamma\Delta u+ \delta| u_t|^{p- 1}u_t=\mu| u|^{q- 1}u, \] \[ v_{tt}- (\|\nabla u\|^2_2+ \|\nabla v\|^2_2)^\gamma\Delta v+ \delta| v_t|^{p- 1}v_t = \mu| v|^{q- 1}v,\quad x\in\Omega,\quad t\in[0, T], \] \[ u(0,

Muscle Control of an Extra Robotic Digit

open access: yesAdvanced Robotics Research, EarlyView.
This study compares muscle‐ and movement‐based control for operating a supernumerary robotic thumb. While movement control performs better in the proposed tasks, muscle‐based (EMG) control promotes broader motor learning. The results highlight the promise and challenges of using biosignals for human augmentation, offering new insights into intuitive ...

A linearized difference method for generalized SRLW equation with damping term

open access: yes四川大学学报. 自然科学版, 2019
In this paper, numerical solution of the initial-boundary value problem for the dissipative generalized SRLW equation with damping term is considered. A three-level linearized difference scheme with second order accuracy is proposed.

Energy dissipation and equivalent damping of RC columns subjected to biaxial bending: an investigation based in experimental results [PDF]

open access: yes, 2012
The cyclic behaviour of reinforced concrete columns have been object of many experimental studies in the recent past years. However, the experimental studies on the biaxial response of RC columns are still limited.

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.

Toward Mechanical Intelligence in Robotics

open access: yesAdvanced Robotics Research, EarlyView.
Robots can use their physical bodies to perform functions usually assigned to electronic sensors and controllers. This perspective defines mechanical intelligence through three core operations: filtering inputs, routing mechanical signals, and switching between states.
