Asian Politics &Policy, Volume 18, Issue 3, July 2026.ABSTRACT Gray‐zone activities have become a central feature of security competition in East Asia, particularly in the Taiwan Strait, where persistent military operations blur the boundary between coercion and armed conflict. This study develops a structured threat‐assessment framework for evaluating the intensity of PLA aerial gray‐zone pressure around

台北飛航情報區第二代航情警告避撞系統(TCAS II)之空中接近事件發生頻率與模型分析 [PDF]
, 2013 民航事業首重飛航安全，而在日益擁擠的有限空域中，除了依賴傳統的地面飛航管制服務提供必要的引導和隔離外，航情警告避撞系統(TCAS)更為航機提供了及時、準確的防撞保護指引，以有效減低和避免空中接近事件的發生。本研究針對民國92年1月至94年12月間，飛航台北飛航情報區(Taipei FIR)內裝置第二代航情警告避撞系統(TCAS II)的民航機所發生的空中接近事件進行整理與分析，除對事件內容進行探討外，並應用移動平均、自迴歸分析及支持向量機(SVM)等三種預測技術建立RA事件發生頻率預測模型 ...

Use Windows Operating System for Ultralight Planes Avionic System [PDF]
, 2013 在輕航機上，由於空間與載重量上的限制，並不過用體積與重量較大的機械式儀表，建構電子式的飛航儀表，可以有效減少儀表的空間，並且搭配其它的電子象統，可因應輕航機的小體積，做出小體積且功能強大的航電系統。在挑選與使用航電的作業系統上，是一個問題，因此這邊以Windows為航電的作業率統，做一個評論並設計出輕航機的航電作業系統。On ultralight planes, because its space and weight limit, it shouldn't use heavy and bulky ...
