Closed-form dynamic stability criterion for elastic-plastic structures under near-fault ground motions

open access: yesFrontiers in Built Environment, 2016
A dynamic stability criterion for elastic-plastic structures under near-fault ground motions is derived in closed-form. A negative post-yield stiffness is treated in order to consider the P-delta effect.

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

open access: yesAdvanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

Lightning Impulse Ageing of HV Cable Insulation

open access: yes, 2009
Lightning impulses can lead to accelerated ageing of extruded cables. Electrical behaviour of a dielectric material when experiencing a lightning impulse is different to that for DC or power frequency applied voltages.

Surrogate impulse ground motion for practical simulation of critical nonlinear structural responses

open access: yesFrontiers in Built Environment
Impulse-based representations of earthquake ground motions provide an efficient framework for evaluating critical nonlinear structural responses. However, the direct use of ideal impulse ground motions expressed by Dirac’s delta function may excite all ...

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

To Buy Or Not To Buy? A Behavioural Approach to Examine Consumer Impulse Buying Choice in Various Situations [PDF]

open access: yes, 2013
Impulse buying is a phenomenon that has attracted attention from marketers and consumer researchers for decades. Whilst impulse buying has been studied extensively, there is a gap in our understanding of consumer impulse buying ...

Echo Cancellation - A Likelihood Ratio Test for Double-talk Versus Channel Change [PDF]

open access: yes, 2006
Echo cancellers are in wide use in both electrical (four wire to two wire mismatch) and acoustic (speaker-microphone coupling) applications. One of the main design problems is the control logic for adaptation.

Review: Critical Excitation Problems for Elastic–Plastic Structures Under Simple Impulse Sequences

open access: yesJapan Architectural Review
This review paper treats critical excitation methods and discusses the possibility of a paradigm shift in nonlinear structural dynamics for building structures with hysteresis using input model transformation without structural model transformation. Long‐
