Trajectory planning with residual vibration suppression for space manipulator based on particle swarm optimization algorithm

Advances in Mechanical Engineering, 2017
Space manipulator suffers from vibration problems mainly due to the flexibility of joints and links in a microgravity environment. This article presents a new optimization method of trajectory planning with minimum residual vibration for space ...

On the inverse nodal problems for discontinuous Sturm–Liouville operators

Journal of Differential Equations, 2016
Recently, a new class of inverse problem so-called inverse nodal problems has attracted the attention of researchers. Inverse nodal problems, in turn, consist in constructing operators from given zeros of their eigenfunctions. In this paper, the authors consider an inverse nodal problem for Sturm Liouville operator with jump condition at the point \(x ...

Inverse problems: Dense nodal subset on an interior subinterval

Journal of Differential Equations, 2013
The authors consider the inverse nodal problem for the Sturm-Liouville equations defined on the interval \([0,1]\) with separated boundary conditions. They prove that a twin dense subset of the nodal set in an interior subinterval uniquely determines the potential on the whole interval and the boundary condition parameters.

Microstructure‐Controlled Crack Propagation and Fracture Resistance in MoSiBTiC Alloy Revealed by Multiscale Extended Finite Element Method Modeling

Advanced Engineering Materials, EarlyView.
A two‐dimensional multiscale finite element analysis framework was established for the first‐generation MoSiBTiC alloy, and the mechanical and fracture‐related parameters of the constituent phases were calibrated through experiments and simulations. The framework provides a basis for analyzing crack propagation behavior in its complex microstructure ...

Solution of a discontinuous inverse nodal problem on a finite interval

Mathematical and Computer Modelling, 2006
The inverse nodal problem is studied for the boundary value problem: \[ -y''+(q(x)+l(l+1)x^{-2})y=\lambda y,\; x\in[1,a],\tag{B} \] \(y'(1)=y'(a)+Hy(a)=0,\) where \(a>1,\, l\geq 0,\,q\in L(1,a)\). The potential \(p(x):=q(x)+l(l+1)x^{-2}\) is integrable on \([1,a]\), i.e. (B) is a classical Sturm-Liouville problem.

Updatable Closed‐Form Evaluation of Arbitrarily Complex Multiport Network Connections

Advanced Electronic Materials, EarlyView.
The inverse design of electrically large wave devices often uses reduced‐order multiport models with discrete optimization, requiring many evaluations of complex interconnections between subsystems that differ only in a few blocks. This paper introduces a closed‐form framework enabling efficient Woodbury low‐rank updates of related, previous ...
