Multivariable crashworthiness optimization of vehicle body by unreplicated saturated factorial design

Structural and Multidisciplinary Optimization, 2012
Crashworthiness, influenced unequally by disparate factors such as the structural dimensions and the material parameters, represents a natural benchmark criterion to judge the passive safety quality of the automobile design. The unreplicated saturated factorial design has enjoyed a remarkable success in the factor screening of different industrial ...

Optimized design of the saturated iron core superconducting fault current limiter

2015 IEEE International Conference on Applied Superconductivity and Electromagnetic Devices (ASEMD), 2015
The DC coil, AC coil, and the iron core are key components for a saturated iron core superconducting fault current limiter (SI-SFCL), which determine the device performance in fault current limiting as well as in normal power transmission. They are also have great impact on the size of the device, which are considerable factors influencing the utility ...

Optimal design and modeling of the multi-stage saturable magnetically controlled reactor

2017 Progress In Electromagnetics Research Symposium - Spring (PIERS), 2017
Magnetically controlled reactor (MCR) is a variable inductance which can be used to regulate the reactive power in the utility, and exert positive impacts to the power quality. However, MCR also generates great harmonics and noise which sometimes limit its application.

Optimization of Reverse Saturable Absorber Limiters: Material Requirements and Design Considerations

MRS Proceedings, 1994
AbstractWe present numerical beam-propagation simulations of optimized reverse-saturable absorption (RSA) based optical limiters where the depth of focus of the input beam is much smaller than the thickness of the nonlinear material. The optimization is achieved by allowing the molecular concentration to vary along the propagation path, allowing the ...

The exact D-optimal first order saturated design with 17 observations

Journal of Statistical Planning and Inference, 1982
Abstract The exact D-optimal first order saturated design with 17 observations is given. The upper bound of the determinant of the information matrix is established and a design attaining this value is constructed. The information matrix is proved to be unique and the optimal design contains the B.I.B. design (16, 16, 6, 6, 2).

An algorithmic approach to construct D-optimal saturated designs for logistic model

Journal of Statistical Computation and Simulation, 2018
In this paper, locally D-optimal saturated designs for a logistic model with one and two continuous input variables have been constructed by modifying the famous Fedorov exchange algorithm.

A Design Methodology for the Optimization of Three-Phase SFCL of Saturated Cores Type

IEEE Transactions on Applied Superconductivity, 2018
Superconducting fault current limiters (SFCL) have already demonstrated their viability in electric power grids. The growth in distributed generation sources and an increased interconnection of networks tend to increase the complexity of electric power grids, rising the number of failures, especially short circuits.

Robust optimal controller design for a non-minimum phase boiler system with a saturable actuator

2009 IEEE Control Applications, (CCA) & Intelligent Control, (ISIC), 2009
Dealing with a multivariable non-minimum phase model of a boiler system, a LQG/LTR controller is designed which is well-known for its optimality and robustness. Firstly, the loop transfer function is shaped using LQG method; then, an observer is proposed with the aim of loop transfer recovery.

Design and optimization of PD control system based on saturation

Applied and Computational Engineering
Designing PI, PD, and PID controllers is challenging, but it is an inevitable step if engineers want their systems to perform well. Consequently, control theory was purposed and the system became more complicated. Unfortunately, saturation is hard to prevent. The degree of saturation is an important aspect of the electrical signal process.

D-optimal design applied to binding saturation curves of an enkephalin analog in rat brain

Life Sciences, 1988
The D-optimal design, a minimal sample design that minimizes the volume of the joint confidence region for the parameters, was used to evaluate binding parameters in a saturation curve with a view to reducing the number of experimental points without loosing accuracy in binding parameter estimates.
