Particle Filtering: A Priori Estimation of Observational Errors of a State-Space Model with Linear Observation Equation

open access: yesMathematics, 2021
Observational errors of Particle Filtering are studied over the case of a state-space model with a linear observation equation. In this study, the observational errors are estimated prior to the upcoming observations.

On the Computation of Some Interval Reliability Indicators for Semi-Markov Systems

open access: yesMathematics, 2021
In this paper, we computed general interval indicators of availability and reliability for systems modelled by time non-homogeneous semi-Markov chains. First, we considered duration-dependent extensions of the Interval Reliability and then, we determined

Quantized Fault-Tolerant Control for Descriptor Systems with Intermittent Actuator Faults, Randomly Occurring Sensor Non-Linearity, and Missing Data

open access: yesMathematics, 2022
This paper examines the fault-tolerant control problem for discrete-time descriptor systems that are susceptible to intermittent actuator failures, nonlinear sensor data, and probability-based missing data.

A Bayesian Pipe Failure Prediction for Optimizing Pipe Renewal Time in Water Distribution Networks

open access: yesInfrastructures, 2022
The sustainable management of the water supply system requires methodologies to monitor, repair, or replace the aging infrastructure, but more importantly, it must be able to assess the condition of the networks and predict their behavior over time ...

A reachable probability approach for the analysis of spatio-temporal dynamics in the human functional network

open access: yesNeuroImage, 2021
The dynamic architecture of the human brain has been consistently observed. However, there is still limited modeling work to elucidate how neuronal circuits are hierarchically and flexibly organized in functional systems.

Non-homogeneous dynamic Bayesian networks for continuous data [PDF]

open access: yes, 2011
: Classical dynamic Bayesian networks (DBNs) are based on the homogeneous Markov assumption and cannot deal with non-homogeneous temporal processes. Various approaches to relax the homogeneity assumption have recently been proposed.

Bottom-Up Model of Random Daily Electrical Load Curve for Office Building

open access: yesApplied Sciences, 2021
In the design stage of energy systems in buildings, accurate load boundary conditions are the key to achieving energy supply and demand balance. Compared with the building cold and heat load, the generation of building electrical load has stronger ...

Improvements in the reconstruction of time-varying gene regulatory networks: dynamic programming and regularization by information sharing among genes [PDF]

open access: yes, 2010
<b>Method:</b> Dynamic Bayesian networks (DBNs) have been applied widely to reconstruct the structure of regulatory processes from time series data, and they have established themselves as a standard modelling tool in computational systems ...

A novel factor graph-based optimization technique for stereo correspondence estimation

open access: yesScientific Reports, 2022
Dense disparities among multiple views are essential for estimating the 3D architecture of a scene based on the geometrical relationship between the scene and the views or cameras.
