A Gaussian Process Data Modelling and Maximum Likelihood Data Fusion Method for Multi-Sensor CMM Measurement of Freeform Surfaces

open access: yesApplied Sciences, 2016
Nowadays, the use of freeform surfaces in various functional applications has become more widespread. Multi-sensor coordinate measuring machines (CMMs) are becoming popular and are produced by many CMM manufacturers since their measurement ability can be

Modeling a Circadian Surface

open access: yesJournal of Biological Rhythms, 2010
Experiments that systematically varied T, τ, and photoperiod in Neurospora crassa revealed that the traditional nonparametric and parametric approaches could not explain entrainment for all of the tested conditions. The authors have developed a new approach to understanding entrainment that incorporates several features of the old ...

Bicubic splines and biquartic polynomials

open access: yesOpen Computer Science, 2016
The paper proposes a new efficient approach to computation of interpolating spline surfaces. The generalization of an unexpected property, noticed while approximating polynomials of degree four by cubic ones, confirmed that a similar interrelation ...

Numerical modelling and robust parametric estimation of surfaces useful for representation of tooth flanks

open access: yesComputer Assisted Methods in Engineering and Science, 2023
This paper concerns modelling of surfaces resulting from measurements or from digital simulation of surfaces e.g., tooth flanks, based on the theory of gearing, with intentionally introduced modification usually defined in discrete form.

SURFACE-REACTION MODELS OF PROTOCELLS

open access: yesBIOMAT 2006, 2007
We present a class of models aiming to describe generic protocells hypotheses, improving a model introduced elsewhere[13]. These models, inspired by the 'Los Alamos bug' hypothesis, are composed by two coupled subsystems: a self-replicating molecule-SRM- and a lipid container.
