Enhanced Ninth-Order Memory-Based Iterative Technique for Efficiently Solving Nonlinear Equations

Mathematics
In this article, we present a novel three-step with-memory iterative method for solving nonlinear equations. We have improved the convergence order of a well-known optimal eighth-order iterative method by converting it into a with-memory version.

An impact sensitivity assessment method of spacecraft based on virtual exterior wall

Defence Technology
The impact sensitivity assessment of spacecraft is to obtain the probability of spacecraft encountering the OD/M (orbital debris or meteoroid), which is a prerequisite for survivability assessment of on-orbit spacecraft.

Exponential Splines and Pseudo-Splines: Generation versus reproduction of exponential polynomials

, 2014
Subdivision schemes are iterative methods for the design of smooth curves and surfaces. Any linear subdivision scheme can be identified by a sequence of Laurent polynomials, also called subdivision symbols, which describe the linear rules determining ...

Improving Time Series Data Quality: Identifying Outliers and Handling Missing Values in a Multilocation Gas and Weather Dataset

Smart Cities
High-quality data are foundational to reliable environmental monitoring and urban planning in smart cities, yet challenges like missing values and outliers in air pollution and meteorological time series data are critical barriers.

A New Adaptive Eleventh-Order Memory Algorithm for Solving Nonlinear Equations

Mathematics
In this article, we introduce a novel three-step iterative algorithm with memory for finding the roots of nonlinear equations. The convergence order of an established eighth-order iterative method is elevated by transforming it into a with-memory variant.

Elastomagnetic Sensing for Tension Monitoring of Embedded Steel Rods in FCM bridges: Amplitude-Phase Features with Thermal Decoupling

e-Journal of Nondestructive Testing
Elastomagnetic sensing offers a non-destructive route to estimate axial tension in steel rods, but amplitude-only practices are easily biased by temperature drift, baseline offsets, and measurement noise.
