Improved Inverse Identification of Anisotropic Polymer Properties via FEMU and VFM With Sensitivity Analysis

Polymer Engineering &Science, EarlyView.
Heterogeneous biaxial testing for anisotropic elastic properties identification from full displacement field. ABSTRACT The stretch‐blowing process of PET bottles induces significant anisotropy in mechanical properties due to the differential elongation of macromolecular chains.

Exploration of the Predictive Validity of Middle School Math Screeners

Psychology in the Schools, EarlyView.
ABSTRACT Universal screening is a key element of multi‐tiered systems of support. Relative to literacy, fewer studies have investigated the psychometric properties of math assessments particularly amongst middle school students. We investigated whether outcomes from two types of curriculum‐based measures (CBMs), computational fluency (M‐COMP) and ...

A Comparison of the Validity of Growth Estimates From Early Math Curriculum Based Measures and a Computer Adaptive Test

Psychology in the Schools, EarlyView.
ABSTRACT This study compared the extent to which growth on two types of early math assessments (curriculum‐based measures [CBMs] and computer adaptive tests) predicted end of year performance in broad math skills as well as improvement in broad math skills in Kindergarten (n = 211) and Grade 1 (n = 79) students.

Quantum Iterative Methods for Solving Differential Equations with Application to Computational Fluid Dynamics

Advanced Quantum Technologies, EarlyView.
Quantum algorithms for differential equations are developed with applications in computational fluid dynamics. The methods follow an iterative simulation framework, implementing Jacobi and Gauss–Seidel schemes on quantum registers through linear combinations of unitaries.

Reductions of GKZ systems and applications to cosmological correlators

Journal of High Energy Physics
A powerful approach to computing Feynman integrals or cosmological correlators is to consider them as solution to systems of differential equations. Often these can be chosen to be Gelfand-Kapranov-Zelevinsky (GKZ) systems.

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

International Journal of Robust and Nonlinear Control, EarlyView.
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 ...

Online Adaptation of Data‐Driven Controllers for Unknown Nonlinear Systems

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper considers data‐driven online control of input‐affine nonlinear systems. By resorting to a data‐based closed‐loop time‐varying system representation, we derive data‐based online semi‐definite programs that are computed along the system's trajectory.

Uncertainty Quantification in Planning Aircraft Ground Movement Operations With Towbarless Robotic Tractors

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This article addresses the problem of quantifying the uncertainty in planning aircraft ground movement operations using towbarless robotic tractors taking into account the inherent uncertainties of the problem, specifically, the uncertainties in the weight of the aircraft and in the rolling resistance of the wheels of the main landing gear ...

Initial State Privacy of Nonlinear Systems on Riemannian Manifolds

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT In this paper, we investigate initial state privacy protection for discrete‐time nonlinear closed systems. By capturing Riemannian geometric structures inherent in such privacy challenges, we refine the concept of differential privacy through the introduction of an initial state adjacency set based on Riemannian distances.
