Complementary Condensing for the Direct Multiple Shooting Method

2012
In this contribution we address the efficient solution of optimal control problems of dynamic processes with many controls. Such problems typically arise from the convexification of integer control decisions. We treat this problem class using the direct multiple shooting method to discretize the optimal control problem. The resulting nonlinear problems

Shoot Tip Culture of Helianthus annuus-Flowering and Development of Adventitious and Multiple Shoots

American Journal of Botany, 1984
Shoot multiplication of Helianthus annuus was optimal from half shoot apices cultured on MS media with 0.1–1.0 mg/1 benzyl adenine or kinetin. Auxins inhibited multiplication and promoted callusing. Rooting was poor and was not promoted by auxins. Flowering of multiple shoots was observed after as little as 3 wk of culture.

NUMERICAL TREATMENT OF MINIMAX CONTROL PROBLEMS BY MULTIPLE SHOOTING

Annual Review in Automatic Programming, 1985
This paper presents the application of multiple shooting techniques to minimax optimal control problems. A standard transformation is used to convert the minimax problem into an equivalent optimal control problem with state variable inequality constraints. Using this technique the highly developed theory on the necessary conditions for state-restricted

Multiple Shooting Using Interval Analysis

BIT Numerical Mathematics, 1985
Gegeben ist das lineare Randwertproblem \[ y'(x)=A(x)y(x)+f(x),\quad x\in [a,b],\quad C_ ay(a)=\alpha,\quad C_ by(b)=\beta. \] Dabei bezeichnen A(x) eine \(n\times n\)-Matrix, y(x) und f(x) n-Vektoren, \(C_ a\) eine \(p\times n\)-Matrix und \(C_ b\) eine (n-p)\(\times n\)-Matrix. Teilt man das Intervall [a,b] in m Teilintervalle \(X_ k:=[x_{k-1},x_ k]\)

Posttrauma Reactions Following a Multiple Shooting

1993
This chapter describes an investigation of psychological reactions among the survivors of a multiple shooting that occurred in a Melbourne city office block on December 8, 1987. Nine people died and a further five were injured in an incident that has become known as the Queen Street Shootings. The research was undertaken to examine levels of posttrauma

Regeneration of multiple shoots and plants from Mesembryanthemum crystallinum

Plant Cell Reports, 1991
Mesembryanthemum crystallinum plants have been regenerated via organogenesis from hypocotyl, cotyledonary node, and leaf expiants with varying frequencies. The highest regeneration frequencies were obtained from either hypocotyls (23-34%) or cotyledonary nodes (21-41%). Leaf expiants yielded very poor regeneration frequencies (0-11%).

Smoothing the function of the multiple-shooting equation

Applied Mathematics & Optimization, 1991
Consider the \(n\)-dimensional boundary value problem \[ y'(x)=f(x,y)= \begin{cases} f_ 1(x,y)\quad &\text{if }a\leq x < s_ 1,\\ f_ 2(x,y)\quad &\text{if } s_ 1\leq x < s_ 2,\\ \vdots \\ f_{l+1}(x,y) \quad&\text{if }s_ l \leq x\leq b,\end{cases} \] when \(f_ i\) are smooth, with the boundary conditions \(R(y(a),y(b))=0\), together with certain ...

In vitro shoot multiplication of Ziziphus spina-christi by shoot tip culture

2012
In vitro shoot multiplications were obtained successfully from shoot tips of Ziziphus spina-christi by placing explants into solidified medium (MS medium) supplemented with 0.01 mg/l NAA and 0.1 mg/l BA or 0.1 mg/l IAA and 1.0 mg/l kinetin. It was concluded that lower concentrations of all cytokinin studied were better for lateral bud proliferation and

Variational Multiple Shooting: Theory and Applications

2017
Electric low-thrust propulsion has nowadays found wide application in space dynamics as it entails considerable savings in spacecraft propellant mass, thanks to the very high specific impulse that this kind of engine is able to generate. However, continuous thrust opens new extensive sets of feasible trajectories, and optimization algorithms are needed
