大型鋼構造物の建造工程導入に向けたレーザ・アークハイブリッド溶接技術の適応範囲拡張に関する検討

Department of Civil and Structural Engineering, Graduate School of Engineering

現在の溶接技術において大入熱溶接に伴う変形や機械的性質の劣化は喫緊なる課題である．本課題を解決する新溶接技術として，レーザ溶接法とアーク溶接法を組み合わせたレーザ・アークハイブリッド溶接法が存在するが，その研究内容や実用化の多くは下向の溶接姿勢に限られる．生産現場のニーズを考慮すれば横向や立向などの溶接姿勢にも対応できることが望ましい．本研究はハイブリッド溶接施工法の適応範囲拡張に関する内容である [...]

I study the spectrum of Schrödinger operators. It is known that the temporal behavior of a quantum system can be characterized by the classification of the spectrum, with point spectrum corresponding [...]

The net-zero target and relating regulations pressure firms to adopt low-emission production and marketing practices. As firms must invest in low-emission technologies to meet these new standards, suc [...]

Transit-oriented development (TOD) is defined as the integration of transport systems and land use, has been put forward as an effective sustainable planning strategy. TODs have been applied in differ [...]

「不気味の谷現象」における原因理論の特定研究／Identifying the most appropriate theory to explain the uncanny valley effect

Department of Behavioral and Health Sciences, Graduate School of Human-Environment Studies

「不気味の谷現象」の原因を明らかにするために，これまでに多くの理論が提唱されてきた。初めて９つの代表的な理論を同一実験内で検証した研究が2021年に公開されたが，この研究にも幾つかの問題点がある。そこで本研究は「追試＋α」の方法で行う。まず，先行研究を追試して，再現可能性を検証する。そして，統制群や VR（仮想現実）技術の導入などを通じて先行研究の問題点を修正し，全体処理や非典型などの理論の説 [...]

The Tenjin area of Fukuoka City, where many commercial and business functions are concentrated, has established a multi-level walking network with ground and underground level connections, large-scale [...]

This project plans to examine the influence of firm-shareholder distance on cash management efficiency. Specifically, we plan to test the hypothesis that geographic distance increases information coll [...]

Developing and Shaping Sustainable Tourism in the Digital Age: Roles and Future Prospects from the Perspective of Inbound Tourist Review Sites

Department of Integrated Sciences for Global Society, Graduate School of Integrated Sciences for Global Society

The progression of over tourism has made the sustainable development of tourism a critical issue. It is urgent to reduce the disparities in the ability to attract visitors between regions to disperse [...]
