游柏峰, Yu, Po-Feng Unknown Date (has links)
論文綱要 本文藉由波特教授之國家競爭優勢理論以及做為參考指標之主要工業國發展過程的研究,歸納出結論,另以總體分析法--運用各種具體指標由上而下加以分析之,亦即在國家的層次上定義國家競爭力,然後找出影響國家競爭力的因素,最後加以綜合分析,促進對於國家綜合的競爭能力表現之了解。第一章緒論探討本文研究動機、目的與方法,第二章針對波特教授的菱形鑽石體系與競爭發展四階段理論分析,並以其理論兼論我國發展情勢,第三章為各國產業發展過程的比較研究,重點在於以鑽石體系四要素來檢視發展進程,並論述九十年代以後各國發展情形,最後則綜合歸納政府政策對於各國產業影響。第四、五章為我國競爭力優劣勢研究,主要依照「行政院提昇國家競爭力行動小組」所擬定之項目與洛桑國際管理學院(IMD)之競爭力排名加以分析,第六章結論探討本文主要發現,政策性意涵與啟示以及未來可能之發展。 / The major theory of dissertation according to Michael Porter's "National Competitive Theory" and the other facts, which would affect National Competitiveness Advantage. Then, conclude all of facts and make it meaningful. Chapter 1 describes about the motive and method of this research. Chapter 2 aims to the Diamond determinants of national advantage, also usethis theory to analyze Taiwan's recent competitive situation.Chapter 3 mainly talking about the industrail developing process of advancedcountry, include USA, Switzerland, Swedwn,Germany,Japan,Italy,UK and Korea,also compare with each other's different apperance after 90's.Chapter 4 and 5 focus on Taiwan's Competitiveness Report by IMD .Chapter 6 is conclusion and major discoveries of the whole dissertation.

Design Techniques for Secure IoT Devices and Networks

Malin Priyamal Prematilake (12201746) 25 July 2023 (has links)
<p>The rapid expansion of consumer Internet-of-Things (IoT) technology across various application domains has made it one of the most sought-after and swiftly evolving technologies. IoT devices offer numerous benefits, such as enhanced security, convenience, and cost reduction. However, as these devices need access to sensitive aspects of human life to function effectively, their abuse can lead to significant financial, psychological, and physical harm. While previous studies have examined the vulnerabilities of IoT devices, insufficient research has delved into the impact and mitigation of threats to users' privacy and safety. This dissertation addresses the challenge of protecting user safety and privacy against threats posed by IoT device vulnerabilities. We first introduce a novel IWMD architecture, which serves as the last line of defense against unsafe operations of Implantable and Wearable Medical Devices (IWMDs). We demonstrate the architecture's effectiveness through a prototype artificial pancreas. Subsequent chapters emphasize the safety and privacy of smart home device users. First, we propose a unique device activity-based categorization and learning approach for network traffic analysis. Utilizing this technology, we present a new smart home security framework and a device type identification mechanism to enhance transparency and access control in smart home device communication. Lastly, we propose a novel traffic shaping technique that hinders adversaries from discerning user activities through traffic analysis. Experiments conducted on commercially available IoT devices confirm that our solutions effectively address these issues with minimal overhead.</p>

台灣政府競爭力之國際評比研究:IMD與WEF報告

陳慧棻 Unknown Date (has links)
每年由IMD及WEF所公佈的國家競爭力報告皆為眾人討論的焦點,然而近年來的國家競爭力報告指出台灣在政府方面的競爭力有大幅改進的必要,因此本文之研究目的在於針對IMD及WEF近年來所提出的國家競爭力報告中的政府相關指標加以整理,並進一步觀察2000~2006年的競爭力報告中,台灣於政府相關細項指標的排名狀況為何,最後再歸納出台灣政府的強弱項指標。 本研究歸納出IMD是以公共財政、財政政策、制度架構、企業法令、社會體制架構、基本的基礎建設、科技基礎建設、科學基礎建設、健康和環境及教育等十個面向來評估政府競爭力,WEF則是從八大類指標來看待台灣政府競爭力:制度、基礎建設、總體經濟、健康和基礎教育、高等教育及訓練、市場效率、科技準備度及創新。 經由次級資料研究法,本研究發現台灣政府的優勢指標有以下三項:(一)高科技產業為台灣優勢項目(二)高等教育普及(三)知識移轉管道順暢;至於台灣政府競爭力的弱勢指標則有五項:(一)公部門運作效能低落(二)政策及政府的不穩定(三)健康與環境不佳(四)雇用外籍勞工限制嚴格(五)司法不獨立。 最後,針對上述的優勢及弱勢指標本研究分別提出強化優勢指標及改善弱勢指標的政策建議,強化優勢指標之政策建議:(一)高科技產業可嘗試發展領導性品牌(二)以「學習」為導向的教育方式(三)活絡產學合作管道之人才運用;針對台灣政府弱勢指標的改善建議則為:(一)公部門體制改造(二)發展正確的「台灣識別」(三)「問題導向」的公共衛生政策(四)彈性地引進外籍勞工(五)藉助多元管道監督司法獨立。本研究嘗試將台灣所面臨的競爭力問題作一詳盡地歸納及整理,並以長期間的資料分析點出台灣政府目前所具備的優勢及未來應急需改善的競爭力指標,希冀以實務性的角度提供台灣政府一參考性的競爭力問題輪廓。

Improved frequency domain measurement techniques for characterizing power amplifier and multipath environments

McKinley, Michael Dean 19 August 2008 (has links)
This work focuses on fixing measurement inaccuracies to which models and figures of merit are susceptible in two wireless communication environments: power amplifier and multipath. To emulate or rate the performance of these environments, models and figures of merit, respectively, are often used. The usefulness of a model depends on how accurately and efficiently it emulates its real-world counterpart. The usefulness of a figure of merit depends on how accurately it represents system behavior. Most discussions on the challenges and trade-offs faced in modeling nearly always focus on the complexity of the device or channel of interest and the resultant difficulty in describing it. Similarly, figures of merit are meant only to summarize the performance of the device or channel. At some point, either in generation or verification of a model or figure of merit, there is a dependence on measured data. Though the complexity and performance of the device or channel are challenges by themselves, there are other significant sources of distortion that must be minimized to avoid errors in the measured data. For this work, the unique distortion of power amplifier and multipath environments is considered, and then errors in measurement which would obscure these distortions are eliminated. Specifically, three measurement issues are addressed: 1) identifying measurement setup artifacts, 2) achieving consistent measurement results and 3) reducing variations in the environment. This work contributes to increasing the accuracy of microwave measurements used in the modeling of nonlinear high-power amplifiers and used in figures of merit for power amplifiers and multipath channels.
