Topology optimization with supershapes [PDF]
Structural and Multidisciplinary Optimization, 2018 This work presents a method for the continuum-based topology optimization of structures whereby the structure is represented by the union of supershapes. Supershapes are an extension of superellipses that can exhibit variable symmetry as well as asymmetry and that can describe through a single equation, the so-called superformula, a wide variety of ...

A topology optimization method for rarefied gas flows
Nihon Kikai Gakkai ronbunshu, 2017 We construct a topology optimization method for two dimensional rarefied gas flow problems, based on level-set boundary expressions. The degree of rarefaction is expressed by the Knudsen number, which is the ratio of the mean free path and the ...

Dynamical systems and topology optimization
Structural and Multidisciplinary Optimization, 2010 This paper uses a dynamical systems approach for studying the material distribution (density or SIMP) formulation of topology optimization of structures. Such an approach means that an ordinary differential equation, such that the objective function is decreasing along a solution trajectory of this equation, is constructed.

Optimal Low-Latency Network Topologies for Cluster Performance Enhancement [PDF]
arXiv, 2019 We propose that clusters interconnected with network topologies having minimal mean path length will increase their overall performance for a variety of applications. We approach our heuristic by constructing clusters of up to 36 nodes having Dragonfly, torus, ring, Chvatal, Wagner, Bidiakis and several other topologies with minimal mean path lengths ...

Topological Optimal Transport for Geometric Cycle Matching [PDF]
arXivTopological data analysis is a powerful tool for describing topological signatures in real world data. An important challenge in topological data analysis is matching significant topological signals across distinct systems. In geometry and probability theory, optimal transport formalises notions of distance and matchings between distributions and ...

Topological and Topographical Optimization of Automotive Spring Lower Seat
Latin American Journal of Solids and StructuresThe design of a suspension system emphasizes weight reduction in this high-computation technology era. Understanding that the reduction of suspension mass can lead to cost and material reduction is important; moreover, the riding performance of the ...

Multi-material topology optimization of an electric machine considering demagnetization [PDF]
arXivWe consider the topology optimization problem of a 2d permanent magnet synchronous machine in magnetostatic operation with demagnetization. This amounts to a PDE-constrained multi-material design optimization problem with an additional pointwise state constraint.

A novel topology design approach using an integrated deep learning network architecture [PDF]
arXiv, 2018 Topology design optimization offers tremendous opportunity in design and manufacturing freedoms by designing and producing a part from the ground-up without a meaningful initial design as required by conventional shape design optimization approaches. Ideally, with adequate problem statements, to formulate and solve the topology design problem using a ...
