A socio-technical approach to broadband diffusion by SMEs [PDF]

open access: yes, 2008
Technological deterministic theories such as Diffusion of Innovations (DOIs) theory provide a useful view of the diffusion process of new technologies. However, the view provided is limited, as it mainly looks at the supply side of the diffusion process ...

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 ...

Testing Jump-Diffusion in Epileptic Brain Dynamics: Impact of Daily Rhythms

open access: yesEntropy, 2021
Stochastic approaches to complex dynamical systems have recently provided broader insights into spatial-temporal aspects of epileptic brain dynamics. Stochastic qualifiers based on higher-order Kramers-Moyal coefficients derived directly from time series

Convergence of stochastic process with Markov switching [PDF]

open access: yesМатематичні Студії, 2012
It has been established sufficient conditions for the convergence of a multi-dimensional stochastic process in the case of dependence of the regression function on the environment, which is described by Markov switchings.

Exponential ergodicity of the jump-diffusion CIR process [PDF]

open access: yes, 2015
In this paper we study the jump-diffusion CIR process (shorted as JCIR), which is an extension of the classical CIR model. The jumps of the JCIR are introduced with the help of a pure-jump L\'evy process $(J_t, t \ge 0)$.

Affinity Learning Via Self-Supervised Diffusion for Spectral Clustering

open access: yesIEEE Access, 2021
Spectral clustering makes use of the spectrum of an input affinity matrix to segment data into disjoint clusters. The performance of spectral clustering depends heavily on the quality of the affinity matrix.

A Generalized Diffusion Equation: Solutions and Anomalous Diffusion

open access: yesFluids, 2023
We investigate the solutions of a generalized diffusion-like equation by considering a spatial and time fractional derivative and the presence of non-local terms, which can be related to reaction or adsorption–desorption processes.

Processo de difusão e TQC Diffusion process and TQC

open access: yesGestão & Produção, 1994
No momento em que assistimos em todo o país a uma disseminação em grande escala de conceitos rotulados de modelo japonês de gestão industrial (conceitos difundidos em nível global e aceitos como uma das poucas alternativas viáveis que se apresentam para ...

Diffusion Process in a Flow

open access: yes, 1997
We establish circumstances under which the dispersion of passive contaminants in a forced, deterministic or random, flow can be consistently interpreted as a Markovian diffusion process.
