Real‐Time Fractional Control of an Electrohydraulic System Using Low‐Cost Technology
International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT Advances in control methods for electrohydraulic systems (EHS) improve performance by addressing nonlinearities and unknown parameters, although most studies are limited to numerical simulations. Furthermore, research with experimental validation often relies on high‐performance computing equipment, specialized data acquisition cards, and ...

Moisture Absorption in Highly Porous Closed‐Cell Polymeric Foams
Polymer Engineering &Science, EarlyView.The conventional one‐dimensional hindered diffusion model has been extended into a new Void Filling Hindered Diffusion Model. By quantifying the moisture stored within closed‐cell pores, this model successfully captures the distinct absorption behaviors observed across varying foam thicknesses.

Regularized Kaczmarz Solvers for Robust Inverse Laplace Transforms
MathematicsInverse Laplace transforms (ILTs) are fundamental to a wide range of scientific and engineering applications—from diffusion NMR spectroscopy to medical imaging—yet their numerical inversion remains severely ill-posed, particularly in the presence of ...

Further properties of the Laplace transform on time scales with arbitrary graininess
, 2013 In this work, we generalize several properties of the usual Laplace transform to the Laplace transform on arbitrary time scales. Among them are translation theorems, transforms of periodic functions, integration of transforms, transforms of derivatives ...

Quarterly Journal of the Royal Meteorological Society, EarlyView.An offline methodology is applied to estimate parameters of a convective gravity‐wave scheme using momentum flux (MF) observations from constant‐level balloons (left panels: pdfs of east and west MFs in green from observations and black from EnKF). The approach integrates an ensemble Kalman filter with an expectation‐maximization algorithm and permits ...

Dynamics and thermodynamics of the fast and slow Madden–Julian Oscillation
Quarterly Journal of the Royal Meteorological Society, EarlyView.The results of this study highlight the MJO as a complex phenomenon, the behavior of which is driven by an interplay of thermodynamic and dynamic processes. The MJO's distinct speeds are controlled by different mechanisms: slow MJOs propagate eastward primarily via horizontal moisture advection, fast MJOs by vertical moisture advection.

Not All Missing Data are Equal: Choosing the Right Imputation Method for Binary Datasets
Quality and Reliability Engineering International, EarlyView.ABSTRACT Missing binary predictors are common in reliability, quality control, and industrial decision systems, yet imputation methods are often chosen by convenience rather than evidence. We conduct a Monte Carlo study comparing mode substitution, sequential hot‐deck, missForest, MICE, and KNN with three neighbourhood sizes under MCAR, MAR, and MNAR ...
