Multi‐Objective Robust Controller Synthesis With Integral Quadratic Constraints in Discrete‐Time

open access: yesInternational Journal of Robust and Nonlinear Control, Volume 36, Issue 3, Page 935-954, February 2026.
ABSTRACT This article presents a novel framework for the robust controller synthesis problem in discrete‐time systems using dynamic Integral Quadratic Constraints (IQCs). We present an algorithm to minimize closed‐loop performance measures such as the ℋ∞$$ {\mathscr{H}}_{\infty } $$‐norm, the energy‐to‐peak gain, the peak‐to‐peak gain, or a ...

Shrouded Wind and Water Turbine Analytical Model Extensions for Tip Gaps, Center Bodies, and Flow Blockage

open access: yesWind Energy, Volume 29, Issue 2, February 2026.
ABSTRACT This paper provides improvements to a previously presented simple, accurate, lower order analytical model for predicting the performance of horizontal‐axis shrouded turbines for a wide range of shroud airfoil shapes varying in length, camber, and thickness. The new, extended model incorporates explicit quantitative predictions of those effects

Equivalence Between the Co‐Rotational Finite Element Method and the Absolute Coordinate Formulation in Multibody Dynamics

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 2, 30 January 2026.
ABSTRACT Geometric nonlinearity arises in problems involving large displacements and rotations, where traditional linear assumptions fail. In the finite element community, several formulations have been developed to address these complexities; the corotational finite element formulation (CRF) has proven to be an efficient alternative to generic total ...

Automatic Adaptive and Targeted Localized Refinement in Transient Structural Dynamic Simulations Using the Multiresolution Finite Wavelet Domain Method

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 1, 15 January 2026.
ABSTRACT The multiresolution finite wavelet domain method has been meticulously studied in numerous wave propagation simulations, showing excellent convergence properties and very fast computing times. The multiresolution procedure always starts with the coarse solution, and then finer solutions can be superimposed on the coarse solution until ...

Real‐Time Optimal Control of High‐Dimensional Parametrized Systems by Deep Learning‐Based Reduced Order Models

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 1, 15 January 2026.
ABSTRACT Steering a system towards a desired target in a very short amount of time is a challenging task from a computational standpoint. Indeed, the intrinsically iterative nature of optimal control problems requires multiple simulations of the state of the physical system to be controlled. Moreover, the control action needs to be updated whenever the

Optimizing Instruction to Reduce Element Interactivity in Fraction Multiplication: Recommendations From Cognitive Load Theory

open access: yesApplied Cognitive Psychology, Volume 40, Issue 1, January/February 2026.
ABSTRACT This study examined the effectiveness of two instructional methods for teaching fraction multiplication within the framework of cognitive load theory. Ninety‐three Year 4 students from South East Asian country were randomly assigned to either the High Element‐Interactivity Method (HEIM) or the Low Element‐Interactivity Method (LEIM).
