Error Analysis and Model Adaptivity for Flows in Gas Networks

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2018
In the simulation and optimization of natural gas flow in a pipeline network, a hierarchy of models is used that employs different formulations of the Euler equations. While the optimization is performed on piecewise linear models, the flow simulation is

Probabilistic Rounding Error Analysis of Householder QR Factorization [PDF]

, 2022
When an $m\times n$ matrix is premultiplied by a product of $n$ Householder matrices the worst-case normwise rounding error bound is proportional to $mnu$, where $u$ is the unit roundoff.

Rounding error analysis of the classical Gram-Schmidt orthogonalization process

Numerische Mathematik, 2005
Given an \(m\times n\) matrix \(A\) of full column rank, this paper is concerned with the numerical properties of the classical Gram-Schmidt process (CGS) for computing an orthonormal basis of the space spanned by the columns of \(A\). Based on a backward error bound for the upper triangular factor produced by CGS, it is proven that the loss of ...

Reply to Comment on ‘Self-thinning forest understoreys reduce wildfire risk, even in a warming climate’

Environmental Research Letters
Our previous analysis of mapped records of forest fires in National Parks in Southwestern Australia showed that fires initiated a pulse in flammability (the likelihood of a point being burned by wildfire), but that flammability declined as forests ...

Error Analysis in Numerical Algorithms

Ibn Al-Haitham Journal for Pure and Applied Sciences, 2017
   In this paper, we applied the concept of the error analysis using the linearization method and new condition numbers constituting optimal bounds in appraisals of the possible errors.

Optimization of Multi-Section and Partially Augmented Magnetic Resonance Imaging (MRI) Images for Brain Tumor Classification Using ResNet-50

CommIT Journal
Brain tumor diagnosis is challenging due to complex brain anatomy and tumor variability across imaging views. Traditional methods are manual and error-prone, making deep learning, particularly ResNetbased Convolutional Neural Network (CNN), essential ...
