Optimal bounds for the sine and hyperbolic tangent means by arithmetic and centroidal means in exponential type

AIMS Mathematics, 2021
In this paper, optimal bounds for the sine and hyperbolic tangent means by arithmetic and centroidal means in exponential type are established using the monotone form of L'Hospital's rule and the criterion for the monotonicity of the quotient of power ...

Artificial neural network paradigm of magneto-thermal behavior in tangent hyperbolic hybrid-nanofluid flow [PDF]

Scientific Reports
The study considers the flow behavior of a Magnetohydrodynamic (MHD) tangent-hyperbolic hybrid-nanofluid as it flows on an exponentially stretched surface. Boundary slippage, Joule heating, changes in thermal radiation and convective effects have impacts

Dynamic Hyperbolic Tangent PSO-Optimized VMD for Pressure Signal Denoising and Prediction in Water Supply Networks [PDF]

Entropy
Urban water supply networks are prone to complex noise interference, which significantly degrades the performance of data-driven forecasting models. Conventional denoising techniques, such as standard Variational Mode Decomposition (VMD), often rely on ...

Mitigating the Vanishing Gradient Problem Using a Pseudo-Normalizing Method [PDF]

Entropy
When training a neural network, the choice of activation function can greatly impact its performance. A function with a larger derivative may cause the coefficients of the latter layers to deviate further from the calculated direction, making deep ...

Dynamic Neural Network Model Design for Solar Radiation Forecast

Lontar Komputer, 2022
Sunlight is an energy source that is a gift from God and is a source of life for living things, including humans as caliphs on earth. Judging from its impact, solar radiation is an environmental parameter that has positive and negative effects on human ...
