Introducing Plithogenic Stochastic Processes with an Application to Poisson Process [PDF]

open access: yesNeutrosophic Sets and Systems
In this paper, we study and define the mathematical form of plithogenic stochastic processes PSP based on set of three classic stochastic processes. This new definition is a generalization of neutrosophic stochastic process.

A finite-difference method for linearization in nonlinear estimation algorithms [PDF]

open access: yesModeling, Identification and Control, 1998
Linearizations of nonlinear functions that are based on Jacobian matrices often cannot be applied in practical applications of nonlinear estimation techniques. An alternative linearization method is presented in this paper.

Dimensionality Reduction of Multivariate Functional Data Using FPCA

open access: yesProceedings of the International Conference on Applied Innovations in IT
In many scientific and engineering applications, data are collected over discrete, often equidistant, time intervals. While such data can be analyzed using traditional statistical methods, these methods are often very limited in their ability to capture ...

Random regression analyses using B-splines to model growth of Australian Angus cattle

open access: yesGenetics Selection Evolution, 2005
Regression on the basis function of B-splines has been advocated as an alternative to orthogonal polynomials in random regression analyses. Basic theory of splines in mixed model analyses is reviewed, and estimates from analyses of weights of Australian ...

The cost function of the data fusion process and its application [PDF]

open access: yesAtmospheric Measurement Techniques, 2019
When the complete data fusion method is used to fuse inconsistent measurements, it is necessary to add to the measurement covariance matrix of each fusing profile a covariance matrix that takes into account the inconsistencies.

QUANTITATIVE ANALYSIS OF BANDED STRUCTURES IN DUAL-PHASE STEELS

open access: yesImage Analysis and Stereology, 2011
Dual-Phase (DP) steels are composed of martensite islands dispersed in a ductile ferrite matrix, which provides a good balance between strength and ductility.

Covariant Anomalies and Functional Determinants

open access: yesFortschritte der Physik/Progress of Physics, 1994
We analize the algebraic structure of consistent and covariant anomalies in gauge and gravitational theories: using a complex extension of the Lie algebra it is possible to describe them in a unified way. Then we study their representations by means of functional determinants, showing how the algebraic solution determines the relevant operators for the
