Topology optimized microbioreactors

Biotechnology and Bioengineering, 2010
AbstractThis article presents the fusion of two hitherto unrelated fields—microbioreactors and topology optimization. The basis for this study is a rectangular microbioreactor with homogeneously distributed immobilized brewers yeast cells (Saccharomyces cerevisiae) that produce a recombinant protein.

Topology optimization for the design of porous electrodes

Structural And Multidisciplinary Optimization, 2021
Porous electrodes are an integral part of many electrochemical devices since they have high porosity to maximize electrochemical transport and high surface area to maximize activity.

Metric-topological–evolutionary optimization

Inverse Problems in Science and Engineering, 2011
This article shows a novel approach for optimization and inverse problems based on evolutionary computation with the aim to satisfy two opposite requirements: exploration and convergence. The proposed approach is particularly suitable for parallel computing and it gives its best both for multimodal problems and for problems in which bad initializations

Adopting the Topology Optimization in the Design of High-Speed Synchronous Reluctance Motors for Electric Vehicles

IEEE transactions on industry applications, 2020
This article deals with the design of high-speed synchronous reluctance motors for electric vehicle applications. The need to enhance the power density and to lower the cost leads to research on high-speed motors with a reduced amount of rare earth. Pure

A topological derivative method for topology optimization

Structural and Multidisciplinary Optimization, 2007
We propose a fictitious domain method for topology optimization in which a level set of the topological derivative field for the cost function identifies the boundary of the optimal design. We describe a fixed-point iteration scheme that implements this optimality criterion subject to a volumetric resource constraint. A smooth and consistent projection

Metalens Topology Optimization

Inquiry@Queen's Undergraduate Research Conference Proceedings
Photonic metasurfaces are thin optical elements comprised of structures arranged strategically upon a surface to manipulate electromagnetic waves. To produce metasurfaces at a large scale, it is beneficial to obtain not just an optimal design, but also ...

Neural Network Topology Optimization

2005
The determination of the optimal architecture of a supervised neural network is an important and a difficult task. The classical neural network topology optimization methods select weight(s) or unit(s) from the architecture in order to give a high performance of a learning algorithm.

Optimization of the Topology of Photoresistors [PDF]

Measurement Techniques, 2004
Phenomenological definitions of generation-recombination noise, survival time, and the photoelectric gain factor for photoresistors are given. The optimal – i.e., from the point of view of detectability – topology in the case where shaded portions of the sensitive element are applied is determined.

Freeform metasurface design based on topology optimization

MRS bulletin, 2020
Metasurfaces are thin-film electromagnetic devices with subwavelength-scale geometric structuring. They can be tailored to produce a broad range of optical functions due to the strong relationship between electromagnetic response and geometric shape.
