The main goal of the thesis was to discover the relation between Taiwan economic development and women position with respect to the analysis of trade liberalization in Taiwan (especially after 1990) and its influence on Taiwanese economic status of women and their opportunity to participate in trade. The thesis uses descriptive analysis which is one of the quantitative method as a mean to interpret the selected data to discuss the changing role of women in the economic development of Taiwan. The conclusions from the thesis are as follows. The economic development of Taiwan has placed women at the important position. In just fifty years, Taiwan has experienced rapid economic development, which transformed the industrial structure to the service sector. After becoming officially a member of WTO in 2002, the female labor participation rate has continued to grow year by year up to more than 50% till today and most of the women participate in the service sector. Till 2014, average hourly payment of men has been 15% higher than the one of women, though the women reached higher level of education.The rising women position in the society affects that women not only postpone the age of getting married and having a baby, but also the fertility rate has been reduced to 1.1 in Taiwan.

The theses explains the Evolution Packet System (EPS) and subsystem IP Multimedia Subsystem (IMS). It also informs how these systems cooperate and through which interfaces the main data and signals between these two technologies are transfered. The thesis includes practical section, in which installation and configuration of sections of the IMS system including its "core", and application and medial server. For verification of the functionality of the system, two dissimilar clients are installed, and emulator WAN is applied for simulation of Internet. The product of the theses is the design of the laboratory exercise drafted in such a way that it can be solved by students less knowledgeable of the issues.

Die Dissertation von L. Zuckerman (auch bekannt als Layla Zami) erforscht die Wechselbeziehungen zwischen Erinnerung, Bewegung, Diaspora und Zeit/Raum in Tanzproduktionen des 21. Jahrhunderts. In einer innovativen transkulturellen, transdisziplinären und transtemporalen Perspektive setzt die Publikation den Akzent auf die Solo-Arbeiten von sieben zeitgenössischen Choreograph_innen, die in Deutschland, Frankreich, Taiwan, Martinique, Palästina und den USA leben, und Interpret_innen ihrer eigenen Stücke sind. Ausgehend von der Hypothese, dass Körper eine zentrale Rolle in der Aushandlung und Überwindung von Machtverhältnissen spielen, fragt die Forschung was geschehen kann, wenn tanzende Körper die Vergangenheit in die Gegenwart transportieren, im materiellen und im metaphorischen Sinne. Die Autorin leitet ein neues Konzept ein, das im Englischen sowohl Substantiv als auch Verb ist: (to) perforMemory. Sie reflektiert die Besonderheiten der Ausdruckform Tanz in der Darstellung, Herstellung, und Tradierung von kultureller Erinnerung im Bezug auf historische Traumata wie der Holocaust, der Transatlantische Sklavenhandel, die Maafa, die Nakba und zeitgenössische gesellschaftspolitische Herausforderungen. Das als Spirale konzipierte Buch lädt zu einer Wanderung durch diasporische Tanz_schaften, in denen sich Fragestellungen zu Identität, Körperlichkeit, Zugehörigkeit, Räumlichkeit und Zeitlichkeit entfalten, und sich in der Diskussion von bestimmten Tanzsequenzen wechselseitig beleuchten. Die Doktorarbeit basiert auf den Ergebnissen einer vierjährigen internationalen Forschung. Die Quellen schöpfen aus unterschiedlichen Fachrichtungen, u.a. Gender und Queer Studies, Tanz/Performance, Kulturwissenschaften, Erinnerung, Postkoloniale Studien, Literatur, Quantenphysik, und Lyrik. Die Veröffentlichung beinhaltet ebenfalls die vollständigen Transkripte von persönlichen Gesprächen, die die Autorin mit den Künstler_innen Oxana Chi, Zufit Simon, Wan-Chao Chang, André M. Zachery, Farah Saleh, Christiane Emmanuel und Chantal Loïal aufgenommen hat, sowie Links zu Performance-Ausschnitten. / The dissertation by L. Zuckerman (aka Layla Zami) explores the interrelations and interactions between memory, movement, diaspora, and spacetime in 21st century dance productions. In an innovative transcultural, transdisciplinary and transtemporal approach, the publication focuses on solo works by seven contemporary dancers-choreographers based in Germany, France, Taiwan, Martinique, Palestine and the USA. Contending that corporeality is a site and a source of power, the research asks what happens when moving bodies propel the past into the present, metaphorically and materially. The author introduces a new concept: (to) perforMemory, which is both a noun and a verb, and discusses the specificity of dance in the production and transmission of cultural memory in relation to historical trauma such as the Holocaust, the Transatlantic Slave Trade, Maafa, the Nakba and contemporary sociopolitical challenges. Conceived in a spiral-like fashion, the book takes the reader through diasporic dancescapes in which notions of identity, home, embodiment, spatiality and temporality unfold and are brought into resonance with each other in the discussion of specific dance examples. The theoretical references connect such various fields as gender studies, dance and performance studies, cultural memory studies, postcolonial studies, literature, quantum physics, queer studies and poetry. Based on doctoral research conducted across the globe from 2013 to 2017, the electronic publication also features the full interview transcripts of personal conversations recorded by the author with the artists Oxana Chi, Zufit Simon, Wan-Chao Chang, André M. Zachery, Farah Saleh, Christiane Emmanuel and Chantal Loïal, as well as links to audiovisual performance excerpts. / La thèse explore les interrelations et interactions entre mémoire, mouvement, diaspora et espace-temps dans la danse au XXIème siècle. Dans une approche transculturelle, transdisciplinaire et transtemporelle, la publication se concentre sur des pièces solo chorégraphiées et interprétées par sept chorégraphes contemporain.e.s basé.e.s en Allemagne, France, Martinique, Palestine, à Taiwan et aux Etats-Unis. Estimant que les corps humains sont objets et sujets de relations de pouvoir, la thèse étudie ce qui se passe lorsque les corps dansent le passé au temps présent, au sens propre et au sens figuré. L'auteure introduit un nouveau concept: (to) perforMemory, à la fois un substantif et un verbe en anglais. Elle met en relief la spécificité de la danse comme forme de production et transmission de la mémoire culturelle, en relation avec des traumas historiques tels que l'Holocauste, la Traite triangulaire ou Maafa, la Nakba ainsi que des défis sociopolitiques contemporains. Conçu comme une spirale, le livre est une invitation au voyage à travers des paysages diasporiques dansés, dans lequel les notions d'identité, d'appartenance, de spatialité, de temporalité et de représentation émergent tour à tour, et s'illuminent mutuellement dans l'analyse de séquences de danse concrètes. Le corpus théorique puise dans des domaines aussi variés que les études de genre, la danse, les études postcoloniales, la litérature, les Cultural Studies, la physique quantique, les études queer et la poésie. Basée sur des recherches doctorales conduites de 2013 à 2017 à travers le monde, cette publication électronique comprend également les transcriptions intégrales des entretiens personnels menés avec les artistes Oxana Chi, Zufit Simon, Chantal Loïal, Christiane Emmanuel, Farah Saleh, Wan-Chao Chang, et André M. Zachery, ainsi que des liens vers des extraits audiovisuels de spectacles.

This study has developed a method to create an, to a big extent, automated testing system for NMP (Networked Music Performance) communication over LAN and WAN to be able to benchmark the UDP streaming engine JackTrip using a client-server model. The method is not locked into using JackTrip only, it could be used to do experiments with other engines too. The study tried to answer the question if latency correlates to amount of correctly aligned audio, and to what extent the audio is correctly aligned in respect to tolerated latency (based on earlier research) when at least two musicians remote-conducting musical pieces together. There were 13 different buffer settings tested, which used no redundancy and redundancy of 2, and which were sent through 4 different LAN/WAN-scenarios. A big dataset was produced, with about 82 minutes’ worth of audio per test. To post-process the data a phase cancelling method was used to measure correctly aligned audio, while the latency was measured by counting the number of samples from the start of each audio file to the first sample that were not null or not under a certain threshold. The results showed clear correlations of buffer sizes impact of latency and amount of correctly audio sent over the network. If the buffer sizes are greater, it will produce higher latency and increase the amount of correctly aligned audio, and on the opposite side, if using less buffer, it will produce lower latencies and less correctly aligned amount of audio. The study also showed that there was very little impact of using higher redundancies, both regarding latency and amount of correctly audio. When analysing the amount of correct data when respecting the tolerated level of latency, the study showed a support for correctly aligned amount of streamed audio up to 65% when using JackTrip. / Den här studien har utvecklat en metod för att skapa ett, till stor del, automatiserat testsystem för NMP-kommunikation (Networked Music Performance) över LAN och WAN för att kunna prestandatesta den UDP-strömmande ljudmotorn JackTrip, med en klient-server-modell. Metoden är inte låst till att endast användas med JackTrip, den kan användas för att göra experiment med andra motorer också. Studien försökte svara på frågorna om latens korrelerar med mängden korrekt justerat ljud, och till hur stor del som ljudet är korrekt justerad med hänsyn till tolererbar latens (baserat på tidigare undersökning) när minst två musiker fjärrmusicerar tillsammans. Det testades 13 olika buffertinställningar, som använde ingen redundans samt med redundans på 2, och som kördes genom 4 olika LAN / WAN-scenarier. En stor datamängd producerades, med ca 82 minuters ljud per test. För att post-bearbeta data användes en fas-elimineringsmetod för att mäta mängden korrekt justerat ljud, medan latensen var uppmätt genom att räkna antalet samplingar från starten av varje ljudfil till den första samplingen som inte var innehållslös eller inte under ett specifikt tröskelvärde. Resultaten visade tydlig korrelation av buffertstorlekens påverkan av latens och mängd korrekt ljud skickat över nätverket. Om buffertstorlekarna är större kommer det att ge högre latens och öka mängden korrekt justerat ljud, och tvärtom, om mindre buffert används, kommer det att ge lägre latens och mindre rätt justerad mängd ljud. Studien visade också att det gav mycket liten effekt att använda högre redundans, både vad gällande latens och mängden korrekt ljud.  Vid analys av mängden korrekta data med hänsyn till den tolererade latensnivån visade studien ett stöd för korrekt justerat mängd av strömmat ljud upp till 65% vid användning av JackTrip.

International Telemetering Conference Proceedings / October 26-29, 1998 / Town & Country Resort Hotel and Convention Center, San Diego, California / Current changes in the way that large flight test systems are utilized have affected the industry’s methodology in both the early design phases and in the implementation of nextgeneration hardware and software. The reduction of available RF spectrum, the implementation of packet telemetry methods and systems, and a desire to implement commercial-off-the-shelf (COTS) hardware are only some of the considerations that telemetry systems integrators and product houses have to face. This paper describes how test methodology changes affect current large systems design at both government test ranges and at airframe/missile manufacturer test facilities. In addition, consideration is given to the area of increased processing power as it affects hardware and software design, the leveraging of such current and future telecommunications technology as network switch technology and compression, cross utilization, standardized technology, and the movement toward platform-independent software.

防火牆是現今網路中的重要設備，負責區隔內部網路和公共網路，維護內部網路安全。然而防火牆也存在幾個重要的問題，首先，防火牆的規則是由網管人員設定，近年來隨著網路科技蓬勃發展、虛擬技術大量應用，此項工作已帶給網管人員龐大的負擔。其次，防火牆雖可隔離外部網路，阻擋有害流量，但對內部網路的防範卻毫無用武之地。目前市面上普遍使用入侵偵測系統(IDS)進行偵測，但僅能在發現攻擊行為後發出警告訊息，無法即時處理。最後，企業在連外網路部分，通常採用多條線路進行備援，並倚賴多路頻寬負載平衡器(Multi-WAN load balancer)增加頻寬的使用率，但在線路數量上卻受限於廠商所制定之規格，無法彈性調整。而在負載平衡演算法方面，也只能基於網路特徵(IP位置)、權重比例(weight)或是輪詢機制(round robin)，無法依據目前網路狀況做出更好判斷。 為改善上述問題，本論文在軟體定義網路(SDN)環境下，使用交換機取代傳統防火牆設備，透過封包分析與信任觀測區間達到規則學習，並整合Snort入侵偵測系統，透過特徵比對，找出危害網路環境之封包，即時阻擋該危險流量。本論文也提出基於隨需(on demand)概念，動態調整防火牆規則，降低管理人員負擔。最後利用交換機擁有多個實體通訊埠的概念 ，依需求可自由調整對外及對內線路數量，不再受限於廠商規格，取代傳統多路寬頻負載平衡器，建構更彈性的架構。並透過收集交換機上的實體埠與資料流表中的資訊，即時評估網路狀況，加強負載平衡。為驗證本論文所提出之⽅法的有效性，我們使用Linux伺服器架設KVM、OpenvSwitch以及POX控制器實際建構SDN網路環境，透過發送封包對防火牆提出請求，以驗證實驗方法的正確性。 根據實驗結果顯示，本論文所提出之概念均能正確運作，有效降低調整防火牆所需之人工作業。在多路寬頻負載平衡器部分，本研究所提出之負載平衡方法，與round robin負載平衡方法相較之下，在最佳情況下，能有效提升約25%平均頻寬使用率，並降低約17.5%封包遺失率。 / Firewall is an important device that is responsible for securing internal network by separating Internet from Intranet, but here are several existing issues about the firewall. First, the firewall rules are set by the network admistrator manually. Along with the vigorous development of Internet technologies and great amount of applications of virtual technology in recent years. This work burdens the network adminstrator with a heavy workload. Second, the firewall is able to isolate the external network from harmful traffic, however, it can do nothing to the internal network. The common situation is to use IDS to detect the harmful packet, but it can only send an alert message to the adminstrater, no more actions can be done. Finally, most companies use several ISP connections to assure fault tolerance and use Multi-WAN load balancer to integrate those connections to enhance bandwidth utilization. But the number of WAN/LAN ports is set by the manufacturer, and the load balance algorithm is also limited by the manufacturer. It offers only a few algorithms (network-based features, round-robin, etc.), and there is no other way to provide more efficient algorithms. In order to resolve the mentioned problems, we propose an automatic firewall based Software Defined Network (SDN). We use Openflow switches to replace traditional firewalls, the system is able to learn the rules automaticlly by packet analysis during an observation interval. We aslo integrate Snort Intrusion Detection System (IDS) to localize the dangerous packets and block them immediately. Next, we propose an on-demand based dynamic firewall rules adjustment mechanism which is able to reduce management workload. Finally, we implement a Multi-WAN load balancer architecture and provide a more efficient load balance algorithm by collecting port usage and firewall rule information. In order to verify the proposed methods, we implement a SDN environment by using Linux Ubuntu servers with KVM, Open vSwitch and POX controller. According to the experiment result, it proves that the proposed method is able to reduce the firewall configuration effectively. In the Multi-WAN load balancer, experiment results show that our method outperforms round-robin argrithom in terms of average bandwidth utilization and packet loss rate by 25% and 17.5%, respectively.

This report describes a thesis work carried out at ABB Robotics in Västerås. The objective of this thesis is to find technologies  and equipments  for wireless data transfer  suitable for the present and future needs of ABB Robotics Remote Service for large installations in industrial environments. ABB Robotics has a Remote Service solution to securely gather information from robots, manage alarms and potentially execute remote commands by ABB Robotics. This solution consists of an intelligent Service  Box plugged to the robot. This  Service Box is also connected through GPRS or directly through Internet to create a secure VPN connection to a central Remote Service  server. The Remote Service Box is well  suited  for small customers with  1-10 robots with plug  and play installation, but show limitations at a larger scale of deployment  due to equipment costs,  network and installation complexity. A new Service Box is planned that will accommodate future added functionality to Remote Service. This Service Box will require new network solutions as the added functionality  is depending on a higher bandwidth than the GPRS networks can deliver. I have surveyed most existing  wireless  networking technologies  and  analyzed  them  withrespect  to function, cost and availability which provide a knowledge base that makes it possible to find  suitable  solutions. When the most suitable technologies are identified a survey was performed to find equipments that meet the requirements at the lowest cost. A new hierarchical network topology is proposed  that will lead to cost savings by replacing multiple WAN connections in the present solution with  a network switch and  single WAN connection to Internet. As manufacturers of network equipments for industrial environments are relatively few, alternative solutions were also investigated in order to find the most cost effective solutions. The  proposed  network topology together with the data from the surveys lead to recommendations on using Wi-Fi  in the wireless LAN and  a  3G mobile  network for the WAN connection to Internet, as well as recommendations on alternative network equipments that  potentially  can  lead to substantial savings when the new network solutions are implemented.
