No full textThe political role of the people's liberation army 1949-1973
Full text linkThis thesis is to study the political role of the People's Liberation Army from the approach of structure and function. The framework of the thesis consists of three major parts, first, the influence of Chinese traditional political culture on, and the formation of, the political role of the PL A; second, the influence of domestic political struggles and external military conflicts on the development of the political role of the PLA; and the third, the analysis of the transition of the PLA's political role from the structure and personnel arrangements of the CCPCC Within the above-mentioned three scopes, this thesis make a thorough discussion on the following: (1) The relationship between the structure of the PRC and the formation of the PLA's political role; (2) How has ideology influenced the army's political role; (3) What is Mao's viewpoint and his influence on the development of the army's political role; (4) What is the link between the army and the party, and how has this developed; (6) What accounts for the expansion of the PLA's political functions; (7) What is the influence of political factional struggles on the PLA's political role; (8) Is it political institution or military institution that controls the recruitment of the military elite; (9) What are the disparities between the military elite in handling international conflicts and what are their political considerations; (10) What is the Party's position in the army; (11) How have the Party’s important meetings and personnel arrangements influenced the rise and fall of the PLA's political role
MECHANISMS FOR ENHANCING THE DEPENDABILITY OF WIRELESS AD-HOC NETWORKS
No full text隨著無線通訊和微機電技術的快速發展，無線移動隨意網路的應用亦逐漸成形；此種網路與生俱來的機動性與彈性使其在特定的領域具有深遠的潛力，例如軍事科技或是災難救援任務。然而在工程上，我們將面臨眾多在提高系統可靠度 (dependability) 與擴展度 (scalability) 上的挑戰，由於此種網路易於缺乏如頻寬或電源等重要系統資源，加上因不具實體的基礎建設而導致網路拓樸結構的不穩定，這些特性都使有關可靠度的議題變得非常棘手。基本上，在設計運作於此種網路的系統時，必需掌握分散式以及只依賴區域性資訊的原則；如此我們將可便於維持某種虛擬的基礎建設，並依此來趨近所欲達成的目標。另一方面，為了應付各式各樣、不知何時會發生的網路原件故障或暫時失效，需導入隨機演算法 (randomized algorithms) 與動態調適 (adaptive)的概念，因為根據相關的文獻顯示，這些概念在行動計算環境中可以有效地增強系統對於錯誤的包容力 (fault tolerance) 和恢復力 (resilience)。
在本論文中，我們研究目的在於提高無線移動隨意網路可靠度。我們主要所採取的方法在於對網路由下而上的數個層面提供特定的容錯機制，經由過往的研究報告和實驗得知，不同網路層面間的行為互動往往對此種網路的效能帶來重大影響。具體來說，我們將重心放在 (1) 網路拓樸控制 (topology control)；(2) 錯誤偵測服務 (failure detection)；(3) 資料的可取得性 (data accessibility)；(4) 系統自行修復能力 (self-repair capacity)。而設計各種機制的主要依據為上段所描述的原理。在每一章節中我們分別對於所提供的機制進行模擬實驗或是數學分析以驗證其效能，而結果均能滿足我們在系統可靠度上欲提高的量測項目 (performance metrics)。我們亦針對各個主題爬梳最新最具潛力的文獻和值得深入探討之方向，冀能激發更創新的研究想法。未來最重要的工作是測試在量產化的機台上整合各網路層面機制後所能獲得的實質效能改善。The advent of wireless ad-hoc networks poses lots of new challenges in the provision of system dependability and scalability. On one hand, these networks are drawing substantial attention in the research community because of their various potential applications. On the other hand, their primary characteristics include scarce resources (e.g., bandwidth, battery power, etc.), a dynamic changing topology, and lack of any physical backbone infrastructureTABLE OF CONTENTS

Yu-Chi Wang
No full textBorn in Taipei City, Taiwan (Republic of China), Yu-Chi Wang earned his Bachelor’s degree in law from National Taiwan University. At the suggestion of one of his professors, Wang applied and was accepted into the Indiana University School of Law’s LLM program. He received the degree in 1993, and later returned to Indiana to become the school’s first Doctor of Juridical Science (SJD) degree recipient.
Wang returned to Taiwan and began a career as an academic, teaching at the Graduate School of Social Informatics at Yuan-Ze University. He also taught in the Department of Law at Shih-Hsin University, becoming a respected and known expert in privacy and telecommunications law. In 2005, Wang joined the Science and Technology Law Center of the Institute for Information Industry, and ultimately became the Center’s Director. From 2008 until 2016, Wang served in the administration of President Ma Ying-Jeou, in a variety of positions, including: Secretary and Spokesperson, Senior Advisor to the National Security Council, and Minister of the Mainland Affairs Council. During his government service, he was the first cabinet member of Taiwan to lead and official delegation to mainland China since the two countries separated. He also was the first Minister to hold official meetings with his mainland China counterpart.
Wang returned to the Department of Law at Shih-Hsin University in 2016 as an associated professor. Yu-Chi Wang is a founding member of the Indiana University Maurer School of Law’s Global Advisory Board and was inducted into the Maurer School of Law’s Academy of Law Alumni Fellows in 2018.https://www.repository.law.indiana.edu/notablealumni/1146/thumbnail.jp
