Adaptive Neuro‐Fuzzy Inference System‐Long Short‐Term Memory Hybrid Model to Forecast Castability of Al‐Killed Steel Prior to Continuous Casting

steel research international, EarlyView.
A novel, hybrid, data‐driven model is developed to assist steelmakers in minimizing production interruptions caused by submerged entry nozzle (SEN) clogging. The modeling architecture is specifically designed to analyze variations in steel chemistry and stopper rod changes, employing a data‐driven approach combined with metallurgical and industrial ...

Augury and Forerunner: Real‐Time Feedback Via Predictive Numerical Optimization and Input Prediction

Computer Graphics Forum, EarlyView.
Transient information generated by solver steps can inform future objective function minimization. In Augury, we explore the impact of predictive numerical optimization by using solver history to predict future minimization solutions, reducing computational resources needed to arrive at convergent states for a broad class of gradient‐based optimization

Development and evaluation of a Hadamard transform imaging spectrometer and a Hadamard transform thermal imager [PDF]

A spectrometric imager and a thermal imager, which achieve multiplexing by the use of binary optical encoding masks, were developed. The masks are based on orthogonal, pseudorandom digital codes derived from Hadamard matrices.

Cointegrating Polynomial Regressions With Power Law Trends

Journal of Time Series Analysis, EarlyView.
ABSTRACT The common practice in cointegrating polynomial regressions (CPRs) often confines nonlinearities in the variable of interest to stochastic trends, thereby overlooking the possibility that they may be caused by deterministic components. As an extension, we propose univariate and multivariate CPRs that incorporate power law deterministic trends.

A practical multi-spectrum Hadamard Transform Spectrometer [PDF]

A Hadamard Transform Spectrometer (HTS) which simultaneously obtains fifteen infrared spectra, each having 255 spectral elements was constructed. Spectra are obtained essentially in real time through use of a minicomputer with 8K words of memory and a ...

A lightweight physics‐data‐driven method for real‐time prediction of subgrade settlements induced by shield tunneling

Computer-Aided Civil and Infrastructure Engineering, EarlyView.
Abstract Real‐time prediction of subgrade settlement caused by shield tunneling is crucial in engineering applications. However, data‐driven methods are prone to overfitting, while physical methods rely on certain assumptions, making it difficult to select satisfactory parameters. Although there are currently physics‐data‐driven methods, they typically

IMAGE COMPRESSION BY USING WALSH AND FRAMELET TRANSFORM

Mağallaẗ Al-kūfaẗ Al-handasiyyaẗ, 2019
In this paper, Framelet and Walsh transform are proposed for transformation, and then using arithmetic coding for compress an image. The goal is to achieve higher compression ratio by applying two levels Framelet transform (FLT), and then apply 2D Walsh ...

An integrated texture and depth isomorphic imaging and cross‐modal network for rail surface defect detection and measurement

Computer-Aided Civil and Infrastructure Engineering, EarlyView.
Abstract Rail defects significantly impact train operations, even posing serious safety risks. Existing methods can automatically collect images from the rail surface and identify apparent defects while facing challenges such as high false positive rates, visually subtle defects omit errors, and quantitative defect size measurement.
