Simultant: simultaneous curve fitting of functions and differential equations using analytical gradient calculations

open access: yesBMC Bioinformatics, 2022
Background The initial step in comparing mathematical models to experimental data is to do a fit. This process can be complicated when either the mathematical models are not analytically solvable (e.g. because of nonlinear differential equations) or when

Modifications of object sizes and box capacities to achieve a simultaneous fitting

open access: yesDiscrete Mathematics, 1977
AbstractGiven a set of k objects of positive integral sizes {si} and a set of n boxes of positive integral capacities {b1} we define a compatibility relation between each box and some subset of objects such that the condition si ⪕ b1 is necessary but not sufficient for object i to be compatible with box j.

Capturing Outlines of Planar Generic Images by Simultaneous Curve Fitting and Sub-division [PDF]

open access: yesJournal of Artificial Intelligence and Data Mining, 2020
In this paper, a new technique has been designed to capture the outline of 2D shapes using cubic B´ezier curves. The proposed technique avoids the traditional method of optimizing the global squared fitting error and emphasizes the local control of data ...

Estimating Fuel Loads and Structural Characteristics of Shrub Communities by Using Terrestrial Laser Scanning

open access: yesRemote Sensing, 2020
Forest fuel loads and structural characteristics strongly affect fire behavior, regulating the rate of spread, fireline intensity, and flame length. Accurate fuel characterization, including disaggregation of the fuel load by size classes, is therefore ...
