人類自有歷史以來，權力的競逐或文明的流動即從未停歇，其所造成的衝突與影響更是複雜無比。911事件是否為杭廷頓教授所言之文明衝突，抑或是源於美國霸權失衡的中東政策所造成的影響？俱為本論文欲試圖探索的中心命題。 911事件深刻地改變了美國對於本土以及國際安全環境的思維，全球安全環境亦因而隨之改變。恐怖主義與文明衝突成就了美國難得的戰略機遇，美國除藉此確立其全球優勢地位外，更大幅擴張其國際活動的空間與戰略運用，相對於國際間反美勢力的聲浪，明顯地對小布希政府的外交政策與全球戰略造成威脅與諷刺。 尤以阿拉伯世界而言，巴勒斯坦問題的無解、美國霸權的過度介入、令人垂涎的石油與經濟等利益，造成中東國家反美反西方情緒高漲，甚而恐怖主義因此盛行。凡此種種，均無法簡單的以「文明衝突」之說，解釋東西方間、以色列與巴勒斯坦間長久以來複雜的歷史情仇。 而911事件，只是如同已發生在世界各地無數恐怖行動一樣，都是令人無法接受的暴行，而這些人類所無法容忍的罪行，不只是「凱達」組織，許多國家或組織事實上以正義之名，亦同樣行使過或正在行使這些人類的罪行，因而造成今日世界混亂與暴力循環的惡果。 人類歷史向來無法逃脫弱肉強食的宿命，然而，適者生存卻非強者獨占的道理卻也亙古不變。就遙望未來站在世界頂端的美國而言，當世人引頸企盼或虎視眈眈時，尤應深切牢記全球化的同時，許多國家及其人民因為過去的累積與錯誤，仍在與飢餓和死亡、憤怒與絕望中掙扎與茍活，欲真正消弭恐怖主義、面對中東問題，巴勒斯坦的爭議終必尋得解決之道。

小布希總統及其外交領導團隊執政後，在外交政策取向上，明顯呈現出單邊主義之傾向。小布希政府不僅全力推動彈道飛彈防禦計畫，退出「反彈道飛彈條約」；公開反對「全面禁止核子試爆條約」；並退出「京都議定書」。自此之後，外界探討美國外交政策時，往往將焦點放在單邊主義。因此，單邊主義之定義為何？小布希政府行使單邊主義之動機？以及單邊主義為小布希政府帶來何種影響，為本論文之研究重點。此外，2001年突發的911事件，帶給美國多面向的重大衝擊。在外交政策方面，911事件之影響甚為廣泛且深遠，小布希政府之單邊主義傾向是否有所轉變？為本論文之研究核心。 　　為觀察美國外交政策中，有關單邊主義現象與911事件影響，本論文採「系統分析法」為研究途徑，以內外部因素與決策者個人因素為自變項、單邊主義為因變項、911事件為中介變項，逐一探討這些自變項在911事件影響下，小布希政府單邊主義之傾向是否有所改變。此外，本論文亦分析哪些因素對單邊主義有增強或弱化效果？哪項因素則具有關鍵性影響？ 　　從本論文得知：選定之自變項中，屬內部因素之「美國例外論」、「新保守主義」與「官僚政治」具有強烈增強單邊主義之效果；至於「兩黨政治」與「國際體系」則具一般增強效果。另外，屬外部因素之「全球化」與「國際法」對單邊主義具有強烈抑制效果；而「國內民意」則具一般抑制效果。本論文認為影響美國單邊主義外交政策取向之關鍵因素，為小布希總統個人。 　　本論文獲致以下研究結果：一、為單邊、多邊與雙邊主義提供定義與優缺點分析。二、提供美國外交政策的單邊主義發展脈絡。三、分析影響小布希政府單邊主義外交政策取向之來源。四、說明「布希主義」主要內涵。五、證明決策者個人因素對外交決策具關鍵性影響。

This thesis analyzes the supervisory control of the PUMA 700 series robot through a remote computer. Supervisory communication carries the control through MARK II controller, common controller for the PUMA robots, to a standard PC, enabling the development of purpose specific control programming without the knowledge of the VAL (Variable Assembly Language), robot-programming language. Using the supervisory communication feature of PUMA, new control software has been developed in which both VAL commands and interactive control commands can be executed simultaneously. The supervisory communication with the control software enables exploitation of third party applications and additional operating system features. The supervisory communication uses the Digital Data Communications Message Protocol (DDCMP). The frame structure of data messages, which is specific to PUMA robots, is fitted into this protocol. The messages embedded into DCMP are actually logical units, having different abilities and features. Data messages are formed with the interactive control software according to execution requests of the user. This thesis explains the implementation of the communication without using the CRC (Cyclic Redundancy Checking) on the remote computer side and the data messages formed with the interactive control software, which also enables the use of sensory inputs (camera, infrared, sound, color information) to be used for the robot motion control.

This study was conducted to investigate the effects of organoclay type and concentration on the nanocomposites synthesized by &ldquo / In-Situ Polymerization&rdquo / and &ldquo / Prepolymerization&rdquo / methods. In-Situ Polymerization Method was in fact a new route which consisted of dispersing the monomers / propylene glycol, maleic anhydride and o-phthalic anhydride into the galleries of montmorillonite followed by subsequent polymerization. The Prepolymerization Method involved the addition of montmorillonite to the previously synthesized unsaturated polyester. As the first step, all the compositions were prepared by Cloisite 30B, and then for comparison of clay type, nanocomposites containing 3 wt.% of Cloisite 15A and Cloisite 25A were also synthesized. The efficiency of the two methods were compared with regards to their structural, thermal and mechanical properties. According to the results of XRD analysis, in both methods, maximum intercalation was observed when Cloisite 30B was used. An exfoliated structure was obtained in the Prepolymerization Method at 3 wt. % Cloisite 30B content. In all clay types, the increase in the d-spacings of the organoclays was higher when the Prepolymerization Method was applied. With Cloisite 30B, maximum improvement in the impact strength was obtained at 3 wt. % organoclay loading and the In-Situ Method yielded better results leading to a 77% increase in the impact strength at this organoclay loading. Among the organoclay types, Cloisite 15A was found to give rise to maximum increase in the impact strength. With the Prepolymerization Method higher improvement in flexural strength and flexural modulus was obtained owing to the lower styrene content in the crosslinking medium. The elongation at break values followed a decreasing trend with increasing clay content but did not show any significant difference when the clay types were compared.

ABSTRACT CHARACTERIZATION OF KIZILCAHAMAM GEOTHERMAL FIELD BY TRACER TESTING Tevfik Kaya M.S, Petroleum and Natural Gas Engineering Department Supervisor : Assoc. Prof. Dr. Serhat Akin Co-Supervisor : Prof. Dr. Mahmut Parlaktuna September 2005, 107 Pages Kizilcahamam Geothermal Field which is 70 km far from Ankara, has been utilized for Geothermal District Heating System, 25 MWt, 2500 residences capacity, greenhouses heating, thermal facilities since 1994. The average production rate is 350m3/h during the heating season , 150m3/h during the summer season for hot water and yearly average reinjection rate is 114m3/h from the field. The long term projections has been studied concerning on expected pressure decline by matching 10 years field history data which contain dynamic level and temperature data. The pressure decline is 140 kPa in the field between 1999 and 2005 with the existing reinjection rate, if the existing rates do not change, the additional pressure decline which is 120 kPa will be occurred up to 2011. In order to get more information from the field, the fluorescein as tracer has been injected in to the MTA-1, and the samples were collected from the MTA-2, Fethi Bey, IHL-1 and IHL-3 for 3 months. The fluorescein concentration has been detected by using fluorimeter, and tracer concentration time plots were analyzed. The fluoreiscein was detected in short breakthrough time in MTA-2 and Fethi Bey which are close to reinjection well, breakthrough time is longer in IHL-1 and IHL-3. The interpretation of tracer test shows that there is communication between all wells. Tracer concentration time plots were compared with different mathematical models, the best match was obtained with multi-fractured model. These results show that Kizilcahamam field is not homogeneous field. It is expected that increasing the reinjection rate will decrease the pressure decline in the field.

Leo VI (886-912) is an emperor who has suffered from a hostile and inadequate press. He has been portrayed as a weak and careless emperor, known mainly for his dubious parentage and marital exploits. This thesis questions these popular perceptions of Leo, and attempts to present a more realistic account of the emperor and the politics of his age. The aspects of the reign tackled focus on essential elements of Leo's life and rule, presented in a rough chronological framework, and the themes of personal relationships and political ideologies are recurrent. Chapter One examines Leo's relationship with Basil I and his attitude to his Macedonian heritage. Chapter Two considers the fate of the monumental figure of Photios at the emperor's hands. Chapter Three deals with the position and role of the 'all powerful' Stylianos Zaoutzes during the first half of the reign. Chapter Four ponders the origin and meaning of Leo's 'wise' epithet. Chapter Five focuses on the emperor's four marriages. Chapter Six turns to the course of foreign affairs during the reign, concentrating on Bulgaria and the Arab navy, and considers the emperor's attitude towards these military problems. Chapter Seven examines the emperor's relationship with his senatorial officials, focusing on two distinct groups, eunuchs and the generals who originated from families of the eastern frontier. Finally Chapter Eight addresses the tense relationship that existed between Leo and his brother and co-emperor Alexander. What emerges from a consideration of these aspects of Leo and his reign is that this is an emperor who does not deserve the popular perceptions that still persist about him. He was an emperor who forged a 'new' and distinctive imperial style, a style that should not deceive us; he may have been literate, sedentary and city-based, but he was also forceful, strong-willed and conscientious.

The 911 emergency response process is a core component of the emergency services critical infrastructure sector in the United States. Modeling and simulation of a complex stochastic system like the 911 response process enables policy makers and stakeholders to better understand, identify, and mitigate the impact of attacks/disasters affecting the 911 system. Modeling the 911 response process as a series of queue sub-systems will enable analysis into how CI failures impact the different phases of the 911 response process. Before such a model can be constructed, the probability distributions of the inter-arrivals of events into these various sub-systems needs to be identified. This research is a first effort into investigating the stochastic behavior of inter-arrival times of different events throughout the 911 response process. I use the methodology of input modeling, a statistical modeling approach, to determine whether the exponential distribution is an appropriate model for these inter-arrival times across a large dataset of historical 911 dispatch records.

蘇聯解體後，中亞地區出現哈薩克斯坦、烏茲別克斯坦、吉爾吉斯坦、塔吉克斯坦與土庫曼斯坦五個新興國家。中亞不但擁有豐富的自然資源及重要的地緣戰略位置，傳統上屬於俄羅斯勢力範圍的地區，並與中國這個崛起中的國際強權為鄰，這樣一個特殊的地區，自然吸引各種國際勢力競相進入。911事件後，美國軍事力量正式進駐中亞，使其得以牽制俄羅斯與中國，中亞地區再次成為國際政治中的焦點。 上海合作組織是一個成立於2001年新興的國際組織，成員國涵括中國、俄羅斯、哈薩克、烏茲別克、吉爾吉、塔吉克。本文透過「地緣政治研究途徑」，來觀察上海合作組織的發展過程與前景；911事件後中亞地區情勢的變化，以及美國駐軍中亞對於上海合作組織發展的影響。 首先，本文說明上海合作組織的發展過程，以觀察各成員國為解決共同問題的實際運作情形，以及介紹上海合作組織的組織結構。同時，探討上海合作組織的合作基礎，說明上海合作組織的成立是各國間基於共同利益與解決共同問題所形成的結果，並進一步分析各成員國自身加入上海合作組織的地緣政治考量。 其次，本文討論極端主義在中亞發展的情形，藉此探討上海合作組織中亞地區成員國之間的內部關係，以及對上海合作組織發展的影響。上海合作組織成立的首要目標是要打擊中亞的極端主義，以維護中亞地區的穩定。 最後，本文說明美國中亞政策的演變，討論911事件後美國駐軍中亞的地緣戰略意涵，及其對中國和俄羅斯的衝擊，最後探討911事件對上海合作組織的發展及中亞情勢的影響。 本文認為：冷戰後，中亞地區在全球地緣戰略格局中的地位顯著上升，成為國際強權爭奪的場域，中國與俄羅斯成立上海合作組織的目的，是為追求在中亞地區中取得優勢地位，911事件後美國駐軍中亞，影響了上海合作組織的發展。911事件後，俄羅斯、中國和美國以中亞地區為場景的地緣政治大競賽中，美國暫時取得優勢地位，俄羅斯是後來居上，中國則必須繼續藉由上海合作組織將強與中亞國家的經濟與軍事合作，以維持在中亞地區的影響力。 / After the collapse of the Soviet Union, in Central Asia emerged five states: Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan. These countries are not only have the rich natural resources, but also take the important role of the global geostrategic patterns. Traditionally, Central Asia was viewed as a part of Russian’s influence and is adjacent to China. Beyond question, such an unusual area lures the international powers to engage the affairs of it. Since the 911 event, the U.S. acquired the opportunity to deploy their military in Central Asia. By means of military presence, the U.S. found the way to counteract the influence of Russia and China in Central Asia. Consequently, the Central Asia became the focus in international politics. The Shanghai Cooperation Organization (SCO) was established by China, Russia, Kazakhstan, Kyrgyzstan, Tajikistan and Uzbekistan in 2001. This dissertation examines the origins and prospects of the SCO, analyzes the variation of geostrategic situation in Central Asia, and discusses how the U.S. military presence in Central Asia influenced the development of SCO. Since the end of the Cold War, the Central Asia has played a significant role in global geostrategic patterns. The motive of China and Russia to promote the establishment of SCO in 2001 is to seek the predominance in the Central Asia. After the 911 event, the U.S. military presence appeared in Central Asia. And this fact indeed affected the development of SCO. China, Russia and U.S. as the three main actors of the ongoing New Great Game, which is occurring in Central Asia. The results of the New Great Game are as follow, U.S. temporarily stands on a vantage point in the present days. As for Russia, it takes the second place by controlling the CIS Collective Security Treaty Organization. As regards China, by exerting the SCO to enhance the economic and political ties with Central Asia countries, it still strives to maintain the influence in Central Asia.

Im Kontext der rasanten Stadt- und Verkehrsentwicklung in Subsahara-Afrika haben Motorrad-Taxis in den vergangenen Jahren einen starken Bedeutungsgewinn erfahren. Diese sorgen für die Erreichbarkeit randstädtischer Siedlungsgebiete und erfüllen auch in innerstädtischen Gebieten wichtige Funktionen. Bisherige Studien haben vor allem Aspekte der Verkehrsunsicherheit sowie quantitative Angebotsmerkmale und Nutzerbewertungen der Dienstleistung herausgearbeitet. Auch um die Potenziale für eine Reduzierung ihrer Negativeffekte und für ihre stärkere verkehrsplanerische Einbettung abschätzen zu können, bedarf es darüber hinaus eines besseren Verständnisses ihrer Steuerungsmechanismen. Vor diesem Hintergrund untersucht die vorliegende Studie die Organisation und Regulierung der Motorrad-Taxis am Beispiel der tansanischen Metropole Dar es Salaam. Die Empirie stützt sich auf ein methodisch qualitatives Vorgehen, das sich am Forschungsstil der Grounded Theory und den Argumenten des Southern Urbanism orientiert. Die Analyse und Einordnung der Ergebnisse basiert auf verschiedenen theoretischen Perspektiven der Steuerung sowie auf Konzepten der soziologischen Praxistheorien. Die Arbeit zeigt, welchen Einfluss der lokale Kontext auf das Entstehen der Motorrad-Taxi-Dienstleistung hat und welche Governance-Mechanismen ihre kontinuierliche Integration in den lokalen Markt der Mobilitätsdienstleistungen ermöglichen. Dabei deckt die Studie das enge Zusammenspiel und die Bedeutung von Selbstregulierung, staatlicher Regulierung sowie Konflikten und Kooperation zwischen den beteiligten Stakeholdern auf. Damit trägt die Studie zur Überwindung einer oft unterstellten Dichotomie von ‚informellen‘ und ‚formellen‘ gesellschaftlichen Relationen bei. Darauf aufbauend liefert die Studie außerdem einen empirischen Beitrag zu aktuellen theoretischen Debatten um das Verhältnis von Strukturzwängen in den Städten Subsahara-Afrikas einerseits und den Handlungsmöglichkeiten sozialer Akteure andererseits. / In the context of rapid urbanisation and transport development in Sub-Saharan-Africa motorcycle-taxis have become an important mobility option in recent years. They increase accessibility in peri-urban settlements and provide crucial functions in inner urban areas. Previous studies have contributed to a better understanding of road safety issues and have investigated quantitative service characteristics and user perceptions. However, in order to reduce negative effects and to evaluate the potentials for their consideration in urban transport planning, it is fundamental to also understand the governance of motorcycle-taxis. Against this background, this study investigates the organisation and mode of regulation of motorcycle-taxis in the Tanzanian metropolis of Dar es Salaam. The study is based on a qualitative research design and follows a Grounded Theory approach and the arguments of Southern Urbanism. The analysis of the empirical results is informed by different governance perspectives and concepts from the field of sociological practice theory. The study shows how the emergence of motorcycle-taxis in Dar es Salaam is shaped by the local context and how particular governance mechanisms continuously enable their integration into the local market of mobility services. In that regard the study unveils how self-regulation, state regulation as well as conflicts and cooperation between stakeholders interrelate and what role they play. In that way the study contributes to overcoming the often-assumed dichotomy between ‘informal’ and ‘formal’ social relations. Moreover, based on a social-theoretical analysis the study contributes to current urban theory debates on the relation between the constraints of social structures in the cities in Sub-Saharan Africa on the one hand and the agency of social actors on the other hand.
