Dynamic Neural Network Model Design for Solar Radiation Forecast

open access: yesLontar 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 ...

Negative tangent bundles and hyperbolic manifolds [PDF]

open access: yesProceedings of the American Mathematical Society, 1976
We construct a family of algebraic manifolds which are hyperbolic in the sense of Kobayashi, but whose tangent bundles are not negative.

A new class activation functions with application in the theory of impulse technics

open access: yesJournal of Mathematical Sciences and Modelling, 2018
In this note we define the new activation functions, based on the well-known hyperbolic tangent and half--hyperbolic tangent activation functions. We consider the Hausdorff distance between the ''double step'' function $\sigma^{\ast}(t)$ (resp. function $

A Variable Step-size CLMS Algorithm and Its Analysis [PDF]

open access: yesRadioengineering, 2020
In this paper, a hyperbolic tangent variable step-size convex combination of the least mean square (HTVSCLMS) algorithm is proposed and analyzed. This work avoids the compromise between the convergence speed and the steady-state error for two filters in ...

Hyperbolic tangent tapered slot antenna

open access: yesElectronics Letters, 2010
A tapered slot antenna, the taper section of which is shaped according to a hyperbolic tangent (tanh) function, is proposed. Characteristics of the antenna are experimentally compared with those of a conventional linearly tapered slot antenna (LTSA). The radiation patterns of the proposed antenna measured at 125 GHz exhibit lower sidelobe levels than ...

Radiative flow of hyperbolic tangent liquid subject to Joule heating

open access: yesResults in Physics, 2017
Influence of thermal radiation in MHD stagnation point flow towards an exponentially stretching sheet is studied. Constitutive relation for an incompressible hyperbolic tangent liquid is taken into account.
