Asymptotic farthest points and extreme points

Filomat, 2018
Let X be a normed space, G a nonempty bounded subset of X and fxng a bounded sequence in X. In this article, we introduce and discuss the concept of asymptotic farthest points of fxng in G, which is a new definition in abstract approximation theory.

Extreme points and convolution properties of some classes of multivalent functions

International Journal of Mathematics and Mathematical Sciences, 1996
This paper deals with the extreme points of closed convex hulls of the classes of multivalent functions related to Ruscheweyh derivatives and then these are used to determine the coefficient bounds.

Fast Multi-Label Low-Rank Linearized SVM Classification Algorithm Based on Approximate Extreme Points

IEEE Access, 2018
To solve the problem that traditional multi-label support vector machine (SVM) classification algorithm adopting nonlinear kernel has been severely restricted from being used on large-scale data sets, we propose fast multi-label low-rank-linearized SVM ...

Extreme points, strongly extreme points and exposed points in Orlicz--Lorentz spaces

In this paper, we investigate the extremal structure of the unit ball in the most general classes of Orlicz--Lorentz spaces. the characterizations of extreme points, strongly extreme points, and exposed points are given for Orlicz--Lorentz function spaces $Λ_{φ,ω}$ generated by an arbitrary Orlicz function $φ$ and a non--increasing weight function $ω$,

Certain subclasses of analytic functions with varying arguments

Le Matematiche, 2014
In this paper, we introduce new classes VM(β ) and VN(β ) of analytic functions with varying arguments in the open unit disc U = {z ∈ C : |z| <1}. Some properties such as coefficient estimates, extreme points, distortion theorems for functions f (z ...

Extreme black points in Born–Infeld electrodynamics

European Physical Journal C: Particles and Fields
This article considers the spacetime structure of a charged black hole in the nonlinear Born–Infeld electrodynamics. We discuss a special state of such a black hole in the form of a “black point” with a doubly degenerate horizon, for which the pseudo ...

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.

APPROACH TO DEPRESS THE BOUNDARY EFFECT IN EEMD ANALYSIS BASED ON IMPROVED SVR

Jixie qiangdu, 2015
For the end effect of ensemble empirical mode decomposition（ EEMD）,considering the disadvantages that the extreme extension only uses the value near the endpoints and the support vector regression（ SVR） extension based on data points takes much time,a ...

Subclass of harmonic univalent functions defined by Dziok-Srivastava operator

Le Matematiche, 2013
In this paper we introduce a new class of harmonic univalent functions defined by the Dziok-Srivastava operator. Coefficient estimates, extreme points, distortion bounds and convex combination for functions belonging to this class are obtained and also ...
