Hopfield Neural Networks for Online Constrained Parameter Estimation With Time‐Varying Dynamics and Disturbances

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
This paper proposes two projector‐based Hopfield neural network (HNN) estimators for online, constrained parameter estimation under time‐varying data, additive disturbances, and slowly drifting physical parameters. The first is a constraint‐aware HNN that enforces linear equalities and inequalities (via slack neurons) and continuously tracks the ...

Breaking Boundaries| Cloudy with a Chance of Heat Balls: The Portrayal of Global Warming on The Daily Show and The Colbert Report

open access: yesInternational Journal of Communication, 2013
This study investigates how The Daily Show and The Colbert Report portray global warming in their satirical news segments and guest interviews. Quantitative content analysis is used to examine the explicit claims made regarding the reality, causes, and ...

Climate change in the European Union [PDF]

open access: yes
It is now universally accepted that climate change is happening and that is caused by man’s behaviour. Global warming is accelerating and the average temperature is likely to rise up to 4 degrees by the end of this century if nothing is done.

Enhancing Corrosion Resistance and Mechanical Strength of 3D‐Printed Iron Polylactic Acid for Marine Applications via Laser Surface Texturing

open access: yesAdvanced Engineering Materials, EarlyView.
Laser surface texturing significantly improves the corrosion resistance and mechanical strength of 3D‐printed iron polylactic acid (Ir‐PLA) for marine applications. Optimal laser parameters reduce corrosion by 80% and enhance tensile strength by 25% and ductility by 15%.

Mitigation versus compensation in global warming policy [PDF]

open access: yes
Policy discussions on global warming are focused on mitigation and adaptation. Here the role of ex post compensation as a substitute for ex ante mitigation is considered.

Dynamic Precipitation during High‐Pressure Torsion of a Magnesium–Manganese Alloy

open access: yesAdvanced Engineering Materials, EarlyView.
An ultrafine‐grained alloy is produced by high‐pressure torsion of solutionized Mg–1.35 wt% Mn. Precipitation of nanometer‐scale Mn particles during deformation provides pinning sites. This prevents the formation of a bimodal grain structure and results in a finer grain size than for pure Mg.
