Parameter Identification of Bivariate Fractal Interpolation Surfaces by Using Convex Hulls

Mathematics, 2023
The scope of this article is to identify the parameters of bivariate fractal interpolation surfaces by using convex hulls as bounding volumes of appropriately chosen data points so that the resulting fractal (graph of) function provides a closer fit ...

The Existence of a Convex Polyhedron with Respect to the Constrained Vertex Norms

Mathematics, 2020
Given a set of constrained vertex norms, we proved the existence of a convex configuration with respect to the set of distinct constrained vertex norms in the two-dimensional case when the constrained vertex norms are distinct or repeated for, at most ...

Determining the Viability of an Unbounded Polyhedron for a Switched System

Discrete Dynamics in Nature and Society, 2023
This paper proposes a new method to determine the viability of a switched system on a cone and an unbounded polyhedron. First, we investigate the viability condition on a cone.

Finding the extreme efficient solutions of multi-objective pseudo-convex programming problem [PDF]

AUT Journal of Mathematics and Computing
In this paper, we present two methods to find the strictly efficient and weakly efficient points of multi-objective programming (MOP) problems in which their objective functions are pseudo-convex and their feasible sets are polyhedrons.

LOCAL STABILITY AND NATURAL MOTIONS OF THE MULTI-FACE DOME ROD STRUCTURE

International Journal for Computational Civil and Structural Engineering, 2023
The research  object is a cyclically symmetric construction of a two-tier dome in the form of a convex polyhedron. Load and deflection critical parameters were determined for this construction pyramidal element. The behavior features of the conservative

Robustness Analysis and Controller Design Based on a Generalized Model of Nonisolated Multiphase DC–DC Converter

IEEE Access, 2022
The nonisolated multiphase dc–dc converter (NMDC) has important research value and broad application prospect in fields such as smart grid and new energy vehicles because of its high power density and low output ripple.

CudaPre3D: An Alternative Preprocessing Algorithm for Accelerating 3D Convex Hull Computation on the GPU

Advances in Electrical and Computer Engineering, 2015
In the calculating of convex hulls for point sets, a preprocessing procedure that is to filter the input points by discarding non-extreme points is commonly used to improve the computational efficiency.
