Network Analysis Using Markov Chain Applied to Wildlife Habitat Selection

open access: yesDiversity, 2022
In the present study, behavioral states for habitat selection are examined using a discrete-time Markov chain (DTMC) combined with a network model with wildlife movement data.

Degradation Modeling Based on Wiener Process Considering Multi-Source Heterogeneity

open access: yesIEEE Access, 2020
Degradation modeling using heterogeneous degradation data of a system population is critical for prognostics and health management. The heterogeneity may result from the inherent differences in the degrading systems and measuring instruments, as well as ...

A consensus layer V pyramidal neuron can sustain interpulse-interval coding. [PDF]

open access: yesPLoS ONE, 2017
In terms of a single neuron's long-distance communication, interpulse intervals (IPIs) are an attractive alternative to rate and binary codes. As a proxy for an IPI, a neuron's time-to-spike can be found in the biophysical and experimental intracellular ...

Optimal Maintenance Decision Based on Remaining Useful Lifetime Prediction for the Equipment Subject to Imperfect Maintenance

open access: yesIEEE Access, 2020
Focusing on the fact that the existing research on optimal maintenance decision for remaining useful lifetime (RUL) prediction and imperfect maintenance has low accuracy of RUL prediction and rationality of decision results, an optimal maintenance ...

A Continuous-Time Random Walk Extension of the Gillis Model [PDF]

open access: yesEntropy, 2020
We consider a continuous-time random walk which is the generalization, by means of the introduction of waiting periods on sites, of the one-dimensional non-homogeneous random walk with a position-dependent drift known in the mathematical literature as ...

Nonlinear Step-Stress Accelerated Degradation Modeling and Remaining Useful Life Estimation Considering Multiple Sources of Variability

open access: yesIEEE Access, 2019
In the absence of sufficient degradation data of long-lifetime and highly reliable products, a step-stress accelerated degradation model based on nonlinear diffusion process is proposed to estimate the remaining useful life (RUL), with the advantage of ...

Atmosphere pollution modeling in the case of accident during rocket propellant transportation by trains [PDF]

open access: yesMATEC Web of Conferences, 2019
At present time, in Ukraine the intensive development of solid-propellant missiles takes place. These missiles are called «Grim», «Grim-2», etc. Transportation of rocket propellant very often is carried out by trains.

Stressful Experiences in University Predict Non-suicidal Self-Injury Through Emotional Reactivity

open access: yesFrontiers in Psychology, 2021
Theoretical perspectives on non-suicidal self-injury (NSSI; direct and deliberate self-injury without lethal intent such as self-cutting or hitting) have long underscored the affective regulating properties of NSSI.
