The modified hyperbolic tangent (mtanh or mth) is a special S-shaped function based on the hyperbolic tangent, given by
This function was proposed by Elena Soboleva (of Ukraine) as a utility function for multi-objective optimization and choice modelling in decision-making.
In other papers it is used for approximation of current-voltage characteristics of field-effect transistors and light-emitting diodes.
With parameters a = b = c = d = 1 the modified hyperbolic tangent function reduces to the conventional tanh(x) function, whereas for a = b = 1 and c = d = 0, the term becomes equal to sinh(x).

August 13th open house at the Red Lion Train Station, home of the Red Lion Train Station Model Railroaders and their wonderful O scale layout. Most of the engines seen are MTH Premier, with some Williams and MTH Railking as well.

Hi train friends! Today I wanted to share a quick demonstration of the MTH wifi app using the new dcs wifi interface. I'm pretty pleased with the app itself. My only wish is that when you control a train with the remote it would also correspond on the app.....meaning so if your train is running at 12 smph on your dcs remote it should also say 12smph on the app but it doesn't. With that said it's very welcomed addition to running MTH trains. I was not crazy about the MTH remote, as much as MTH says it's user friendly....it is not! This app is user friendly. Thanks for watching! As always thanks for comments, views and subscribing!
Filmed February 7th, 2016 World's Greatest Hobby made it's return to the Twin Cities since 2010 when it visited the St. Paul RiverCentre. Featured at the MN Free-MO club layout was MTH's new DMIR Yellowstone in HO Scale.
lying on the floor i wonder...were you just too afraid to show?
i guess we'll never know
to this distant ever-after...you didn't want to go
were we blinded by a reason?
watching days refuse to shine...to darkness from divine
such a pity for this lover...you left behind
i never wanted anybody else
i never needed you, i needed help
after the feeling's gone...so long, because it's over
not a healthy situation...push me over, hold me down
to see if i would drown
was i waiting for an answer i didn't want to know?
i never wanted anybody else
i never needed you, i needed help
after the feeling's gone...so long, because it's over
and like the lyrics to a song i sang to you before
you know it fades away
i never wanted anybody else
i never needed you, i needed help
