Fast and numerically stable circle fit
We develop a new algorithm for fitting circles that does not have drawbacks commonly found in existing circle fits. Our fit achieves ultimate accuracy (to machine precision), avoids divergence, and is numerically stable even when fitting circles get ...

An accelerated Levenberg-Marquardt algorithm for feedforward network
Abstract This paper proposes a new Levenberg-Marquardt algorithm that is accelerated byadjusting a Jacobian matrix and a quasi-Hessian matrix. The proposed method parti-tions the Jacobian matrix into block matrices and employs the inverse of a partitionedmatrix to nd the inverse of the quasi-Hessian matrix.

Optimized Dual ANN Control Technique for Efficient Energy Management System (EMS) of Microgrid
Proposed methodology. ABSTRACT The escalating global energy demand necessitates a shift towards sustainable and environmentally friendly alternatives. While renewable energy sources like solar and wind energy offer promising solutions, their intermittent nature poses significant challenges for grid integration.

A trade‐off between efficiency and stability in a class of sky‐blue organic light‐emitting diodes
OLED efficiency and stability are correlated with device structure using combined experimental and simulation approach. Efficient, but less stable devices suffer mainly from exciton‐exciton annihilation, while their opposites have excitons predominantly quenched by polarons.

The handheld Raman with SSE system efficiently mitigates fluorescence; however, it may also bias the Raman response towards graphitic domains in carbon‐based black pigments, thereby concealing amorphous carbon contributions that are critical for pigment type identification.
