Outer Synchronization of Complex-Variable Networks with Complex Coupling via Impulsive Pinning Control

open access: yesMathematics, 2021
In this paper, outer synchronization of complex-variable networks with complex coupling is considered. Sufficient conditions for achieving outer synchronization using static impulsive pinning controllers are first derived according to the Lyapunov ...

Glueball masses and Regge trajectories for the QCD-inspired potential

open access: yes, 2012
Bound state of two massive constituent gluons is studied in the potential approach. Relativistic quasi-classical wave equation with the QCD-inspired scalar potential is solved by the quasi-classical method in the complex plane.

VPE: Variational Policy Embedding for Transfer Reinforcement Learning

open access: yes, 2018
Reinforcement Learning methods are capable of solving complex problems, but resulting policies might perform poorly in environments that are even slightly different.

Estimation and model selection in generalized additive partial linear models for correlated data with diverging number of covariates [PDF]

open access: yes, 2014
We propose generalized additive partial linear models for complex data which allow one to capture nonlinear patterns of some covariates, in the presence of linear components.

Modeling mixed boundary conditions in a Hilbert space with the complex variable boundary element method (CVBEM)

open access: yesMethodsX, 2015
The Laplace equation that results from specifying either the normal or tangential force equilibrium equation in terms of the warping functions or its conjugate can be modeled as a complex variable boundary element method or CVBEM mixed boundary problem ...

Synthesis of Five-Bar Slider Mechanism with Variable Topology for Finitely Separated Positions

open access: yesAdvances in Mechanical Engineering, 2011
A method to synthesize a five-bar slider mechanism with variable topology is suggested. Synthesis is carried out in two phases for function generation. In Phase I, synthesis is carried out for three finitely separated positions.

COMPLEX VARIABLE FUNCTION SOLUTIONS OF STRESS INTENSITY FACTORS FOR MULTIPLE HOLE-EDGE CRACKS

open access: yesJixie qiangdu, 2020
The acceleration effect in the process of collinear hole-edge cracks propagation of aircraft fuselage skin structure is mainly manifested by the interaction of stress intensity factors between multiple fatigue cracks. A modified approximate superposition
