Design and analysis of computer experiments using polynomial regression and Latin hypercube sampling in optimal design of PID controller

Journal of Applied Research on Industrial Engineering, 2018
Computational complexity and time-consuming iteration of simulation for tuning of Proportional-Integral-Derivative (PID) controller is a common drawback in many types of existing methods.

Development of stepwise particle dosing algorithm in magnetic solution deposition to clarify maximum area fraction points

Nihon Kikai Gakkai ronbunshu
We investigated sedimentation in a colloidal dispersion composed of spherical ferromagnetic particles using Brownian dynamic simulations. We developed an algorithm to derive the maximum surface integral rate points, which is the area fraction that ...

Brauer-Manin obstruction for integral points of homogeneous spaces and representation by integral quadratic forms

, 2007
An integer may be represented by a quadratic form over each ring of p-adic integers and over the reals without being represented by this quadratic form over the integers.

Large integral points on elliptic curves [PDF]

Mathematics of Computation, 1987
We describe several methods which permit one to search for big integral points on certain elliptic curves, i.e., for integral solutions (x, y) of certain Diophantine equations of the form y 2 = x 3 + a x +

Integral points on cubic hypersurfaces

, 2006
Let g be a cubic polynomial with integer coefficients and n>9 variables, and assume that the congruence g=0 modulo p^k is soluble for all prime powers p^k.

Integral points on elliptic curves and explicit valuations of division polynomials

, 2014
Assuming Lang's conjectured lower bound on the heights of non-torsion points on an elliptic curve, we show that there exists an absolute constant C such that for any elliptic curve E/Q and non-torsion point P in E(Q), there is at most one integral ...

A Class of Relational Almost Nonlinear Contractions Using (c)-Comparison Functions with an Application in Nonlinear Integral Equations

Mathematics
This work uses (c)-comparison functions in a metric space endowed with an arbitrary binary relation to establish certain fixed point results under a nonlinear version of almost contractions.

Nonlinear Dynamics, Fixed Points and Coupled Fixed Points in Generalized Gauge Spaces with Applications to a System of Integral Equations

Discrete Dynamics in Nature and Society, 2015
We will discuss discrete dynamics generated by single-valued and multivalued operators in spaces endowed with a generalized metric structure. More precisely, the behavior of the sequence (fn(x))n∈N of successive approximations in complete generalized ...
