A Quantum-Based Beetle Swarm Optimization Algorithm for Numerical Optimization

Applied Sciences, 2023
The beetle antennae search (BAS) algorithm is an outstanding representative of swarm intelligence algorithms. However, the BAS algorithm still suffers from the deficiency of not being able to handle high-dimensional variables.

Optimizing Photonic Nanostructures via Multi-fidelity Gaussian Processes [PDF]

, 2018
We apply numerical methods in combination with finite-difference-time-domain (FDTD) simulations to optimize transmission properties of plasmonic mirror color filters using a multi-objective figure of merit over a five-dimensional parameter space by ...

Sharp interface limit for a phase field model in structural optimization

, 2016
We formulate a general shape and topology optimization problem in structural optimization by using a phase field approach. This problem is considered in view of well-posedness and we derive optimality conditions.

Comparative pyrolysis kinetics of various biomasses based on model-free and DAEM approaches improved with numerical optimization procedure

PLoS ONE, 2018
The pyrolysis process of various types of biomass (agricultural and wood by-products) in non-isothermal conditions using simultaneous thermal analyses (STA) was investigated. Devolatilization kinetics was implemented through combined application of model-

FOCUS-HTS: a new stellarator coil design code for three-dimensional high-temperature superconducting magnets

Nuclear Fusion
Stellarators mainly utilize magnetic fields from external coils to confine the plasma, enabling steady-state operation while avoiding instabilities like disruptions raised from plasma currents.

Multi-Objective Optimization of the Hydrodynamic Performance of the Second Stage of a Multi-Phase Pump

Energies, 2017
Most multi-phase pumps used in crude oil production have been developed to satisfy certain pressure specifications. In the design of these pumps, the flow characteristics of the posterior stage are different from those of the prior stage. For this reason,

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Numerical Inductor Optimization

Transactions of the Magnetics Society of Japan, 2002
This paper shows a method for the numerical quality factor optimization of a high frequency inductor based on a genetic algorithm. This is pointed out by an example of a trench-type or I-inductor. A comparison between different design approaches will show the advantages of themselves.
