A Probabilistic Cut Finite Element Method With Random Field Generator and Bayesian Model Calibration for Flow Through Rough Cracks

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT A new model for the simulation of fluid flow through rough cracks is presented. The model combines a probabilistic cut finite element method (PCutFEM) to capture the unfitted boundary condition at the fluid interface, with a stochastic random field generator to represent the crack asperities.

A Critical Review of Pole Clustering Techniques: Common Pitfalls, Extension to MIMO and New Enhanced Variant of the Cuckoo Search Algorithm

Optimal Control Applications and Methods, EarlyView.
Enhanced Cuckoo Search for Model Order Reduction ABSTRACT This article presents a critical review of classical and modern pole clustering techniques for model order reduction in high‐order systems. It highlights key limitations and common pitfalls encountered in traditional approaches, especially when extended to Multi‐Input Multi‐Output (MIMO) systems.

Numerical Simulation of Three‐Dimensional Unsteady Extrudate Swell Through Annular Dies: Effects of Die Core Opening Position and Sag on Parison Formation

Polymer Engineering &Science, EarlyView.
Study on transient parison formation at various strokes during extrusion of Newtonian and viscoelastic fluids. In the presence of an offset between the mandrel and the bushing, Newtonian fluids exhibit a reduction in extrudate diameter, whereas viscoelastic fluids display diameter swelling only at flow rates exceeding a critical threshold.

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.
