A Bridge to Justice: The Life of Franklin H. Williams

為了解決h bar的問題，作者Gort, Enid,Caher, John 這樣論述：

Documents the life of a gifted African-American leader whose contributions were pivotal to the movement for social justice and racial equality Franklin Hall Williams was a visionary and trailblazer who devoted his life to the pursuit of civil rights--not through acrimony and violence and hatred, but

through reason and example. A Bridge to Justice sheds new light on this practical, pragmatic bridge-builder and brilliant yet complex individual whose life reflected the opportunities and constraints of an intellectually elite Black man in the 20th century. Franklin H. Williams was considered a br

idge figure, someone whose position outside the limelight allowed him to navigate both Black and white circles, span the more turbulent racial waters below, and persuade people to see the world in a new way. During his prolific lifetime, he was a civil rights leader, lawyer, diplomat, organizer of t

he Peace Corps, United Nations representative, foundation president, and associate of Thurgood Marshall on some of the seminal civil liberty cases of the past hundred years, though their relationship was so fraught with tension that Marshall had Williams sent to California. He worked in the Kennedy

and Johnson administrations, served as a diplomat, and became an exceptionally persuasive advocate for civil rights. Even after enduring the segregated Army, suffering cruel discrimination, and barely escaping a murderous lynch mob eager to make him pay for zealously representing three innocent Blac

k men falsely accused of rape, Franklin was not a hater. He believed that Americans, in general, were good people who were open to reason and, in their hearts, sympathetic to fairness and justice. Dr. Enid Gort, an anthropologist and Africanist who conducted hundreds of hours of exclusive interview

s with Williams, his family, friends, colleagues and compatriots, and John M. Caher, a professional writer and legal journalist, have co-authored an exhaustively researched and scrupulously documented account of this civil rights champion’s life and impact. His story is an object lesson to help this

nation heal and advance through unity rather than tribalism. Enid Gort (Author) Enid Gort, an anthropologist and Africanist, is a meticulous researcher and writer who conducted hundreds of hours of interviews with Ambassador Williams, his family, colleagues, friends and critics as part of a maste

r’s thesis. She met and worked closely with Ambassador Williams when he was president of the Phelps Stokes Fund and she was director of the Phelps Stokes Institute. Dr. Gort traveled extensively to conduct interviews and re-interviews, sifted through archives and obscure records and became the unpar

alleled expert on Franklin Williams. Her thesis, expanded and updated in partnership with a professional writer, is the backbone of A Bridge to Justice. Dr. Gort has had an eclectic career as a foundation executive, author and professor. She taught medical anthropology at the City University of New

York, edited Aging in Cross-Cultural Perspective: Africa and the Americas (Phelps Stokes Institute, 1988) and contributed articles to academic journals such as Social Science and Medicine and the JournalofAfrican Studies, among others. Her work is also included in the edited volume: African Feminis

m: The Politics of Survival in Sub-Saharan Africa (University of Pennsylvania Press, 1997). Several of Dr. Gort’s articles are published in the Encyclopedia of African-American Culture and History (Macmillan Library Reference, 1996), including an article on Franklin H. Williams. Dr. Gort holds a deg

ree in education from Kean College and master’s and doctorate degrees from Columbia University. In addition, she earned an M.F.A. in Non-Fiction Writing from Columbia and a certificate in Oral History from the same institution. John Caher (Author) John M. Caher has been a professional writer for thr

ee decades and is the author or co-author of seven other books and the principal writer of a PBS documentary on Franklin H. Williams. A former newspaper reporter and editor with approximately 12,000 by-lined newspaper, magazine and law review articles to his credit, Mr. Caher’s books include The Cur

ious Case of Kiryas Joel (Chicago Review Press, 2016) Personal Bankruptcy Laws for Dummies (Wiley; 2007); A Time for Reflection, an autobiography of a former government and business legend, William E. Simon (Regnery, 2003); and King of the Mountain, a biography of former New York Chief Judge Sol W

achtler (Prometheus, 1998). Mr. Caher holds a journalism degree from Syracuse University (Utica College) and a master’s degree in technical communications/ graphics from Rensse-laer Polytechnic Institute. His reporting has garnered more than 20 awards, including prestigious honors from the American

Bar Association, the New York State Bar Association and the Erie County Bar Association. Mr. Caher is a former communications director for a state criminal justice agency and is currently employed by the New York State Unified Court System as Senior Advisor for Strategic and Technical Communications

. He has been honored by the Gender Fairness Committee of the Third Judicial District for his work to advance gender equity, and by the Franklin H. Williams Judicial Commission for his commitment to diversity and racial fairness.

汽車多雷達系統之擴展目標追蹤

為了解決h bar的問題，作者葉冠華 這樣論述：

本論文主要考慮在道路環境中之擴展目標追蹤問題。在擴展目標追蹤中，必須估計運動學及形狀兩種參數。在道路上的目標不會是任意形狀的，通常有數個特定形狀作為候選。為了提高追蹤效能，我們首先提出將形狀估計問題轉換為形狀偵測的問題。計算候選形狀的似然函數，並使用最大似然 (maximum likelihood, ML) 原理進行偵測。一旦偵測到形狀，接著再次使用 ML來估計目標位置，並將結果與追蹤濾波器的輸出相結合。使用上述方法，我們進一步提出了兩種多雷達擴展目標追蹤方法，分散式和集中式方法。由模擬結果所示，所提出的方法明顯優於傳統的擴展目標追蹤方法。

低腔壓高濃度過氧化氫混合式火箭引擎之研究

為了解決h bar的問題，作者林育宏 這樣論述：

本論文為混合式火箭系統入軌段火箭引擎的前期研究，除了高引擎效率的要求外，更需要精準的推力控制與降低入軌段火箭的結構重量比，以增加入軌精度與酬載能力。混合式火箭引擎具相對安全、綠色環保、可推力控制、管路簡單、低成本等優點，並且可以輕易地達到引擎深度節流推力控制，對於僅能單次使用、需要精準進入軌道的入軌段火箭推進系統有相當大的應用潛力。其最大的優點是燃料在常溫下為固態、易保存且安全，即使燃燒室或儲存槽受損，固態的燃料也不會因此產生劇烈的燃燒而導致爆炸。雖然混合式推進系統有不少優於固態及液態推進系統的特性，相較事先預混燃料與氧化劑的固態推進系統及可精準控制氧燃比而達到高度燃燒效率的液態推進系統，混

合式推進系統有擴散焰邊界層燃燒特性，此因素導致混合式推進系統的燃料燃燒速率普遍偏低，使得設計大推力引擎設計時需要長度較長的燃燒室來提供足夠的燃料燃燒表面積，也導致得更高長徑比的火箭設計。針對此問題，本論文利用渦漩注入氧化劑的方式，增加了氧化劑在引擎內部的滯留時間，並藉由渦旋流場提升氧化劑與燃料的混合效率以及燃料耗蝕率；同時降低引擎燃燒室工作壓力以研究其推進效能，並與較高工作壓力進行比較。本論文使用氮氣加壓供流系統驅動90%高濃度過氧化氫 (high-test peroxide) 進入觸媒床，並使用三氧化二鋁 (Al2O3) 為載體的三氧化二錳 (Mn2O3) 觸媒進行催化分解，隨後以渦漩注入的

方式注入燃燒腔，並與燃料聚丙烯（polypropylene, PP）進行燃燒，最後經由石墨鐘形噴嘴 (bell-shaped nozzle) 噴出燃燒腔後產生推力。實驗部分首先透過深度節流測試先針對原版腔壓40 barA引擎在低腔壓下的氧燃比 (O/F ratio)、特徵速度 (C*)、比衝值 (Isp) 等引擎性能進行研究，提供後續設計20 barA低腔壓引擎的依據，並整理出觸媒床等壓損以及燃燒室等流速的引擎設計轉換模型；同時使用CFD模擬驗證渦漩注射器於氧化劑全流量下 (425 g/s) 的壓損與等壓損轉換模型預測的數值接近 (~1.3 bar)。由腔壓20 barA 引擎的8秒hot-f

ire實驗結果顯示，由於推力係數 (CF) 在低腔壓引擎的理論值 (~1.4) 相較於腔壓40 barA引擎的推力係數理論值 (~1.5) 較低，因此腔壓20 barA引擎的海平面Isp相較於腔壓40 barA引擎的Isp 低了約13 s，但是兩組引擎具有相近的Isp效率 (~94%)，且長時間的24秒hot-fire測試顯示Isp效率會因長時間燃燒而提升至97%。此外，氧化劑流量皆線性正比於推力與腔壓，判定係數 (R2) 也高於99%，實現混合式火箭引擎推力控制的優異性能。透過燃料耗蝕率與氧通量之關係式可知，低腔壓引擎在相同氧化劑通量下 (100 kg/m2s) 較腔壓40 barA引擎降低

了約15%的燃料耗蝕率，因此引擎的燃料耗蝕率會受到腔體壓力轉換的影響而變動，本論文也針對此現象歸納出一校正方法以預測不同腔壓下的燃料耗蝕率，此校正後的關係式可提供未來不同腔壓引擎燃料長度設計上的準則。最後將雙氧水貯存瓶的上游氮氣加壓壓力從約58 barA降低至38 barA並進行8秒hot-fire測試，結果顯示仍能得到與過往測試相當接近的Isp效率 (~94%)，而此特性除了能讓雙氧水及氮氣貯存瓶擁有輕量化設計的可能性，搭配具流量控制的控制閥也有利於未來箭體朝向blowdown type型式的設計，因此雙氧水加壓桶槽上的氮氣調壓閥 (N2 pressure regulator valve)

將可省去，得以降低供流系統的重量，並增加箭體的酬載能力，對於未來箭體輕量化將是一大優勢。
