Elastic–Plastic Modeling and Experimental Characterization of Granular Jamming Actuators

Advanced Engineering Materials, EarlyView.
Granular jamming enables rapid switching between soft and rigid mechanical states. Here, a reduced‐order elastic‐perfectly‐plastic beam framework captures pressure‐dependent loading, unloading, residual deformation, and hysteresis in jammed beams, while matching three‐point bending experiments across materials and geometries. The framework links design

Lyapunov and non-Lyapunov stabilty of linear discrete time delay systems

, 2003
This paper extends some of the basic results in the area of Lyapunov (asymptotic) and finite time and practical stability to linear, discrete, time invariant time-delay systems, New definitions have been established for the latter concept of stability ...

Combined effect of loop delay and reference clock jitter in first-order digital bang-bang phase-locked loops [PDF]

, 2009
Paper presented at the IEEE International Symposium on Circuits and Systems (ISCAS), Taipei, Taiwan, 24-27 May 2009Recently, several digital phase-locked loops (DPLLs) have been demonstrated to achieve the jitter performance of traditional charge-pump ...

Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite

Advanced Functional Materials, EarlyView.
The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.

Delay-dependent stability analysis for discrete-time systems with time varying state delay [PDF]

Chemical Industry and Chemical Engineering Quarterly, 2011
The stability of discrete systems with time-varying delay is considered. Some sufficient delaydependent stability conditions are derived using an appropriate model transformation of the original system.

Memristive‐Gated RC‐Delay Synaptic Transistors for Time‐Encoded Analog in‐Memory Computing

Advanced Functional Materials, EarlyView.
A Memristive‐Gated Transistor for Time‐Encoded Analog In‐Memory Computing — By exploiting the RC delay of a self‐rectifying interface‐type memristor, nonlinear I–V distortion is structurally bypassed, enabling 3‐bit nonvolatile memory, spike‐timing‐based analog encoding, and hardware‐calibrated reservoir‐computing validation within a unified device ...

Equivalent systems for differential equations with polynomially distributed delay

Mathematical and Computer Modelling of Dynamical Systems
We consider delay differential equations with a polynomially distributed delay. We derive an equivalent system of delay differential equations, which includes just two discrete delays.

Impulsive control for stabilisation of discrete delay systems and synchronisation of discrete delay dynamical networks

IET Control Theory & Applications, 2014
This study investigates impulsive stabilisation of non‐linear discrete‐time systems with time‐delay. By employing Razumikhin technique and Lyapunov functions, several global exponential stability criteria are established. It is shown that, even if the non‐linear discrete delay systems, in the absence of impulses, are unstable, impulses can ...

On feedback stabilization of nonlinear discrete-time state-delayed systems [PDF]

, 2009
In this paper, we consider the problem of feedback stabilization of discrete-time systems with delays. The systems under consideration are nonlinear and nonaffine.
