Spatiality in small area estimation: A new structure with a simulation study

open access: yesGeospatial Health, 2020
In numerous practical applications, data from neighbouring small areas present spatial correlation. More recently, an extension of the Fay–Herriot model through the Simultaneously Auto- Rregressive (SAR) process has been considered.

A Stochastic Dynamical Model of Slope Creep and Failure

open access: yesGeophysical Research Letters, 2023
We propose a stochastic dynamical model to simulate slope secondary and tertiary creep phenomena. The slope secondary creep is represented by the Kesten process defined as a stochastic affine auto‐regressive process involving both multiplicative and ...

Modelling and analysis of turbulent datasets using Auto Regressive Moving Average processes [PDF]

open access: yesPhysics of Fluids, 2014
We introduce a novel way to extract information from turbulent datasets by applying an Auto Regressive Moving Average (ARMA) statistical analysis. Such analysis goes well beyond the analysis of the mean flow and of the fluctuations and links the behavior of the recorded time series to a discrete version of a stochastic differential equation which is ...

Compound digital filter

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2014
This paper describes the identification by the compound digital filter with two estimators involved in the Kalman filter, the first corresponds to stochastic gradient describing the transition function and the second obtains the innovation process gain ...

Prognosis of Bearing Degradation Using Gradient Variable Forgetting Factor RLS Combined With Time Series Model

open access: yesIEEE Access, 2018
Rolling element bearing is a critical component in many mechanical systems in view of its critical functionality. One of the major issues industries face today is the failure of bearings, which results in catastrophic consequences.

Is Uniqueness Lost for Under-Sampled Continuous-Time Auto-Regressive Processes? [PDF]

open access: yesIEEE Signal Processing Letters, 2012
We consider the problem of sampling continuous-time auto-regressive processes on a uniform grid. We investigate whether a given sampled process originates from a single continuous-time model, and address this uniqueness problem by introducing an alternative description of poles in the complex plane. We then utilize Kronecker's approximation theorem and

Material Procurement Recommendation System for Property Developer Companies using ARIMA and AHP Methods

open access: yesSistemasi: Jurnal Sistem Informasi, 2023
This research aims to help companies to be able to estimate the procurement of materials in property development, control material stocks in warehouses, and determine which suppliers can support to meet these needs with predetermined criteria, namely the
