Stochastic Process and Simulation of Traction Load for High Speed Railways

open access: yesIEEE Access, 2019
The traction load of a high-speed railway (HSR) may cause significant voltage fluctuations in the traction power supply system and the utility grid. To evaluate power quality, modeling traction load is an urgent need as well as a fundamental work.

Probabilistic Models for Competence Assessment in Education

open access: yesApplied Sciences, 2022
Probabilistic models of competence assessment join the benefits of automation with human judgment. We start this paper by replicating two preexisting probabilistic models of peer assessment (PG1-bias and PAAS).

An analytically solvable model of probabilistic network dynamics [PDF]

open access: yes, 2005
We present a simple model of network dynamics that can be solved analytically for uniform networks. We obtain the dynamics of response of the system to perturbations. The analytical solution is an excellent approximation for random networks. A comparison

Modelling Probabilistic Wireless Networks [PDF]

open access: yesLogical Methods in Computer Science, 2013
We propose a process calculus to model high level wireless systems, where the topology of a network is described by a digraph. The calculus enjoys features which are proper of wireless networks, namely broadcast communication and probabilistic behaviour.

Denoising Diffusion Probabilistic Models for Probabilistic Energy Forecasting

open access: yes2023 IEEE Belgrade PowerTech, 2023
Scenario-based probabilistic forecasts have become vital for decision-makers in handling intermittent renewable energies. This paper presents a recent promising deep learning generative approach called denoising diffusion probabilistic models. It is a class of latent variable models which have recently demonstrated impressive results in the computer ...

Probabilistic Graphical Models [PDF]

open access: yes, 2014
This report presents probabilistic graphical models that are based on imprecise probabilities using a simplified language. In particular the discussion is focused on credal networks and discrete domains. It describes the building blocks of credal networks algorithms to perform inference and discusses on complexity results and related work.

An accurate model for SARS-CoV-2 pooled RT-PCR test errors

open access: yesRoyal Society Open Science, 2021
Pooling is a method of simultaneously testing multiple samples for the presence of pathogens. Pooling of SARS-CoV-2 tests is increasing in popularity, due to its high testing throughput.

Phenomenological model of the intensity, duration and frequency of precipitation patterns for the Portoviejo river basin, Ecuador

open access: yesRUDN Journal of Engineering Research, 2022
Phenomenological models represent the behavior of random phenomena in reality, the model and the function it should perform. Similarly, tuning parameters allow us to assess the fit of observed data to a variable in a particular mathematical model and to ...
