On the effects of soil properties on leak noise propagation in plastic water distribution pipes
(2018-08-04)
In many countries, leaks are located in water distribution pipes by using the cross-correlation of pipe vibration measured either side of a suspected leak. However, in modern plastic pipes this can be problematic due to ...
Performance of a Fuzzy ARTMAP Artificial Neural Network in Characterizing the Wave Regime at the Port of Sines (Portugal)
(2016-11-01)
Santos, F.L.; Reis, M.T.; Fortes, C.J.E.M.; Lotufo, A.D.; Neves, D.R.C.B.; Poseiro, P., and Maciel, G.F., 2016. Performance of a fuzzy ARTMAP artificial neural network in characterizing the wave regime at the Port of Sines ...
Numerical study of the generation and propagation of ultralow-frequency waves by artificial ionospheric F region modulation at different latitudes
(European Geosciences Union, 2016-09-21)
Powerful high-frequency (HF) radio waves can be used to efficiently modify the upper-ionospheric plasmas of the F region. The pressure gradient induced by modulated electron heating at ultralow-frequency (ULF) drives a ...
Millimeter-Wave Line-of-Sight Probability Modeling for Inside Metro Carriages Scenarios
(Universidad Nacional Tecnológica de Lima Sur, 2020)
This paper proposes a new Line of Sight (LoS) probability model for metro carriage scenarios to evaluate radio propagation for the future Fifth Generation (5G) Wireless Communications Systems in the Millimeter Wave (mmW) ...
Analysis of sound propagation for outdoor emergency speakers networks
(Institute of Electrical and Electronics Engineers Inc., 2017)
In this work we show the results of analysis of propagation of sound waves applied for an alert system in the river Chili, in Arequipa city. We used mathematical models, ISO standards, geographical, demographical and ...
Gaussian Process NARX Model for Damage Detection in Composite Aircraft Structures
(2022-02-01)
This article demonstrates the Gaussian process regression model's applicability combined with a nonlinear autoregressive exogenous (NARX) framework using experimental data measured with PZTs' patches bonded in a composite ...
Abortive and propagating intracellular calcium waves: Analysis from a hybrid model
(Public Library of Science, 2015-01)
The functional properties of inositol(1,4,5)-triphosphate (IP3) receptors allow a variety of intracellular Ca2+ phenomena. In this way, global phenomena, such as propagating and abortive Ca2+ waves, as well as local events ...
