Dynamic optimization using adaptive direct multiple shooting

Computers & Chemical Engineering, 2014
Abstract We present a wavelet-based grid refinement approach for direct multiple shooting applied to dynamic optimization problems. The algorithm, named adaptive multiple shooting, automatically generates a problem-dependent parameterization of the control profiles: Starting from an initially coarse parameterization, the control grid is refined ...

Multiple Victim Public Shootings

SSRN Electronic Journal, 2001
Few events obtain the same instant worldwide news coverage as multiple victim public shootings. These crimes allow us to study the alternative methods used to kill a large number of people (e.g., shootings versus bombings), marginal deterrence and the severity of the crime, substitutability of penalties, private versus public methods of deterrence and ...

The switching-method in multiple shooting

Computing, 1998
Multiple shooting is a well-known technique for the numerical solution of boundary value problems for ordinary differential equations. In order to solve the boundary value problems one has to solve initial value problems defined in the subintervalls of a given grid of shooting points.

MULTIPLE SHOOT INDUCTION FROM SEED DERIVED SHOOTS OF PAPHIOPEDILUM

Acta Horticulturae, 2010
Shoots, derived from seeds, of Paphiopedilum 'Delrosi' were used as explants for multiple shoot induction. Modified Hyponex medium was supplemented with N 6 -benzyladenine (BA), thidiazuron (TDZ) or kinetin (Kn) alone and in combination with 2,4-dichlorophenoxyacetic acid (2,4-D) or adenine sulphate. All explants were cultured for 15 weeks.

Multiple Shoot Regeneration from Young Shoots of Kenaf (Hibiscus cannabinus)

Plant Cell, Tissue and Organ Culture, 2004
A method was developed to initiate multiple shoots from the young shoot of kenaf. Young shoots along with the cotyledons were excised from ten-day old aseptically germinated seeds and pre-cultured for two weeks in Murashige and Skoog (MS) medium supplemented with benzyl adenine (BA) or a combination of BA and kinetin.

Propagation of potato by shoot-tip culture. 1. Shoot multiplication

Potato Research, 1980
Extensive proliferation via axiallary meristems can be induced in potato shoot-tips (15–20mm) cultured in liquid media. Proliferation is greatest when a 4-week period of shake culture for 1 1/2 h per day is followed by stationary culture. The rate of proliferation is influenced by light, temperature and phytohormones.

Linear convergence of distributed multiple shooting

2014 European Control Conference (ECC), 2014
Distributed multiple shooting is a modification of the multiple shooting approach for discretizing optimal control problems wherein the separate components of a large-scale system are discretized as well as shooting time intervals. In an SQP algorithm that solves the resulting discretized nonlinear program, the adjoint based version of the algorithm ...

Multiple Shooting Techniques Revisited

1983
The present article is a short summary or a more extensive presentation — see [9]. Multiple shooting (MS) techniques as developed in [4,16,19,5] are one of the popular approaches for the numerical solution of (in general nonlinear) boundary value problems (BVP’s) for ordinary differential equations (ODE’s). For alternative approaches see e.g.

Multiple Shooting in a Microsecond

2015
Nonlinear Model Predictive Control (NMPC) is a feedback control technique that uses the most current state estimate of a nonlinear system to compute an optimal plan for the future system behavior. This plan is recomputed at every sampling time, creating feedback. Thus, NMPC needs to repeatedly solve a nonlinear optimal control problem (OCP).

Multiple shooting using interval analysis

BIT, 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 \(X_ k:=[x_{k-1},x_ k]\)
