, 2013 碩士一般而言，橋梁氣動力效應以顫振及抖振最為顯著，也最受到關注。傳統上對於顫振及抖振分析，因實驗技術不易絕大多數僅考量垂直向與扭轉向顫振導數，忽略順風向顫振導數作用之影響。但隨著長跨徑橋梁的出現，忽略順風向顫振導數影響的思維，對於實際存在的氣動力行為可能已經不再保守。此類長跨徑橋梁通常採用輕質材料及纜索支撐系統，側向運動將會比短跨徑橋梁更為顯著，也可能產生順風向與扭轉向之耦合振態。 本文採用斜張橋、懸索橋、吊索拱橋三類纜索支撐橋梁例題，配合文獻中之顫振導數進行顫振與抖振分析。此外，在多振態分析中 ...

Coupled-Mode Flutter for Advanced Turbofans
, 2010 In the vast majority of measured turbomachinery blade flutter occurrences, the response occurs predominately in a single mode. The primary reason for this single-mode flutter is that for turbomachinery applications the combination of high mass ratio ...

ESC Heart Failure, Volume 12, Issue 2, Page 1427-1436, April 2025.Abstract Background and objectives Initially described as a benign acute cardiomyopathy, Takotsubo syndrome has been linked to elevated mortality rates. Emerging evidence suggests that unresolved myocardial inflammation may contribute to this adverse prognosis.

The 2025 Kamchatka Earthquake and Tsunami: Cascading Impacts and Risks to Japan
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT On July 29th, 2025, a large earthquake (Mw 8.8) occurred near the Kamchatka Peninsula. This event caused a tsunami that reached Japan's Pacific coast, even though the source was far away. In this study, we analyze the characteristics of earthquakes and tsunamis and discuss how they relate to the recurrence possibility and risk in Japan.

Human Resource Development Quarterly, Volume 36, Issue 1, Page 89-112, Spring 2025.Abstract Retirees re‐entering the workforce, popularly termed as bridge employment, is a phenomenon that is anticipated to increase in the coming years. Though research establishes that these employees have unique aspirations and work motives (see Mazumdar et al., 2020), primary research on how the retirement transition and bridge employment shape each
