Re-visiting the COVID-19 analysis using the class of high ordered integer-valued time series models with harmonic features

open access: yesHealthcare Analytics, 2022
The COVID-19 series is obviously one of the most volatile time series with lots of spikes and oscillations. The conventional integer-valued auto-regressive time series models (INAR) may be limited to account for such features in COVID-19 series such as ...

Auto Regressive eXogenous (ARX) System Identification of Batch Milk Cooling Process

open access: yesASEAN Journal of Chemical Engineering, 2022
The dynamic model of the milk cooling process from 36°C to 4°C using chilled water available at 2°C has been carried out.  The cooling water temperature is kept constant by using a refrigeration unit. The process being studied was a Packo brand milk cooling tank belonging to KUD SAE Pujon (Malang - Indonesia). A fundamental heat balance method was used

Detection of low-velocity impact-induced delaminations in composite laminates using Auto-Regressive models [PDF]

open access: yes, 2016
In this paper, the detection of delaminations in carbon-fiber-reinforced-plastic (CFRP) laminate plates induced by low-velocity impacts (LVI) is investigated by means of Auto-Regressive (AR) models obtained from the time histories of the acquired ...

Direct and indirect self-tuning generalized minimum variance control [PDF]

open access: yesSerbian Journal of Electrical Engineering, 2019
Theoretically, several self-tuning control (STC) algorithms have been developed and many simulation results have proved their feasibility in the past years, but applications of STC are hardly seen.

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 ...

A frailty-contagion model for multi-site hourly precipitation driven by atmospheric covariates [PDF]

open access: yes, 2014
Accurate stochastic simulations of hourly precipitation are needed for impact studies at local spatial scales. Statistically, hourly precipitation data represent a difficult challenge.

Prediction of weakly locally stationary processes by auto-regression

open access: yesLatin American Journal of Probability and Mathematical Statistics, 2018
In this contribution we introduce weakly locally stationary time series through the local approximation of the non-stationary covariance structure by a stationary one. This allows us to define autoregression coefficients in a non-stationary context, which, in the particular case of a locally stationary Time Varying Autoregressive (TVAR ...
