TLDR
In this article, the authors discuss the effects of gender stereotypes on gender stereotypes in the context of gender discrimination in the media and show that gender stereotypes can be used to discriminate between genders.Abstract:
本研究は, トラス構造物の離散的最適設計法について研究したものである. 本論文の最適化手法は, 初期設計, 応答近似式による検討ランク幅の設定, 連続的近似最適化問題の利用, および部分抽出法より構成される. 列挙法を基本としているが, 近似の概念を随所に利用し, 構造の特性, および連続的近似最適化問題の結果を利用して検討すべき組合せの数を少なくすることに成功し, 実用的な離散的最適設計法を示している.read more

On Discrete Structural Optimization
TL;DR: The application of discrete programming to structural optimization permits the use of tabulated section properties and eliminates the need for approximate relations, such as between weight and section modulus, which may obscure the optimal solution.
