Shifted up cosine function as unconventional model of probability distribution

, 2010
The shifted up one period of cosine function with field under it normalized to 1 is proposed to be use as the un conventional model of probability density function (PDF).

Discretizations of the hyperbolic cosine.

, 2013
This paper explores different notions of a discrete hyperbolic cosine. The interest in this topic arises from the discretization of the catenoid which is a minimal surface of revolution and whose meridian curve is the hyperbolic cosine.

Intelligent Acousto‐Electrical Metamaterials (IAM) for Sound Source Detection

Advanced Materials, EarlyView.
Our proposed metamaterial concept enables sound source detection using a single material, in contrast to conventional arrays that require dozens or even hundreds of transducers. We show that the coupled acoustic–vibrational–electrical responses in piezoelectric metamaterials give rise to topology‐governed charge transport, producing distinct voltage ...

Sine cosine optimization algorithm combined with balloon effect for adaptive position control of a cart forced by an armature-controlled DC motor.

PLoS ONE
For a car that is propelled by an armature-controlled DC motor This study proposes an adjustable linear positioning control. In this paper, to optimize the parameters of the car's position controller the sine cosine optimization algorithm (SCA) is ...
