Fair Share: Senior Activism, Tiny Publics, and the Culture of Resistance

為了解決Extend的問題，作者Fine, Gary Alan 這樣論述：

A deeply researched ethnographic portrait of progressive senior activists in Chicago who demonstrate how a tiny public wields collective power to advocate for broad social change. If you’ve ever been to a protest or been involved in a movement for social change, you have likely experienced a loca

l culture, one with slogans, jargon, and shared commitments. Though one might think of a cohort of youthful organizers when imagining protest culture, this powerful ethnography from esteemed sociologist Gary Alan Fine explores the world of senior citizens on the front lines of progressive protests.

While seniors are a notoriously important--and historically conservative--political cohort, the group Fine calls ＂Chicago Seniors Together＂ is a decidedly leftist organization, inspired by the model of Saul Alinsky. The group advocates for social issues, such as affordable housing and healthcare, th

at affect all sectors of society but take on a particular urgency in the lives of seniors. Seniors connect and mobilize around their distinct experiences but do so in service of concerns that extend beyond themselves. Not only do these seniors experience social issues as seniors--but they use their

age as a dramatic visual in advocating for political change. In Fair Share, Fine brings readers into the vital world of an overlooked political group, describing how a ＂tiny public＂ mobilizes its demands for broad social change. In investigating this process, he shows that senior citizen activists

are particularly savvy about using age to their advantage in social movements. After all, what could be more attention-grabbing than a group of passionate older people determinedly shuffling through snowy streets with canes, in wheelchairs, and holding walkers to demand healthcare equity, risking th

eir own health in the process?

應用於移動式 UHF 射頻充電的高效率且寬輸入範圍之電源管理晶片採用自適應負載/輸入功率匹配技術

為了解決Extend的問題，作者郭浩毅 這樣論述：

近年來由於物聯網的興起，使得環境中佈建的無線感測器之需求快速上升。傳統的無線感測器之能量來源主要藉由化學電池提供，因此要具有較長的生命週期與較小的體積是相當困難的。無線能量擷取技術為透過環境中的能量來驅動電子電路的相關技術，提供無線感測節點所需的能量並且延長電池壽命。RF功率擷取方法是目前最常使用於短距離(數十公尺內)能量傳遞的方法之一，但由於目前的RF能量管理電路的高效率受限於窄小的輸入功率範圍，因此相關的應用依舊十分受限。本論文以應用於物聯網之無線能量擷取系統為出發點，除了使用可重構式技術來改善傳統交直流轉換架構之窄小輸入範圍的能量轉換曲線達成具有大動態輸入範圍之交直流轉換電路外，更藉由

後端包含負載調變電路的MPPT技術與低壓降穩壓器穩定輸出電壓值來提高高輸入功率時整體系統之效率。整體系統以CMOS 0.18μm製程製作，為一個全整合式之積體電路，其寬輸入動態範圍之交直流轉換電路具有54.2%之最佳轉換效率、-19.6dBm之靈敏度與20dB大輸入範圍且高轉換效率(Efficiency > 20%)。高轉換效率的能量擷取與高整合晶片將可以有效地解決過去RF能量擷取的效率不佳及能量浪費等問題，並且可以應用於更多功率以及體積限制的植入式生物感測器系統、智慧感測系統、自動電子收費系統貼片及無線充電等需要無線能量傳輸及穩定輸出電壓值的電路中。

The European Union: What Is It? Is Britain Right to Be Leaving It?

為了解決Extend的問題，作者Lewis, Jane 這樣論述：

History is littered with failed attempts to unite Europe by force, from the Roman Empire and the Byzantine Empire onwards. By contrast, the European Union began as a small and unglamorous attempt to unite the continent after the terrible devastation wrought by the Nazis - in the hope that it would p

revent any further terrible wars. Driven by a handful of mainly French economists and diplomats, men like Jean Monnet, it started out as the modest, very pedestrian-sounding European Coal and Steel Community. Now it is a monolith with its own currency, comprising 28 nations and a total population of

more than 500 million people, and its tentacles extend into all our lives - arguably, its decisions are more important than those of any single national government. In this clear and compelling short book, Jane Lewis tells the story of the European Union, from its modest beginnings to its huge bure

aucratic present. And she asks: has it gone wrong? Is it now really what the founding fathers dreamt of? Is Britain right to be leaving it and how will Brexit affect the EU? Can it survive? Or is it headed irresistibly towards collapse? Jane Lewis is City Editor of The Week and writes profiles for

MoneyWeek. A former British Society of Magazine Editors editor of the year, she studied history at Trinity College, Oxford.

人體脊椎輔助檢測神經網路與系統建構

為了解決Extend的問題，作者陳紀翰 這樣論述：

人體姿態識別為一項長期發展的技術，目前被廣泛地運用在辨識人體 姿態及動作捕捉等技術中，然而，受限於目前姿態識別所標記的 16~25 點關鍵 點尚不足以用來做最重要的檢查 : 人體脊椎，使得人體姿態識別於復健醫學等 領域中的應用仍大幅受到限制，在此研究中，我們提出了神經網路與系統來執 行人體脊椎檢測輔助的工作，此神經網路檢測了相較目前人體姿態識別神經網 路額外 5 個脊椎點及 3 個肋骨點，使得我們可以檢測出頸椎前傾、駝背、骨盆 前傾及軀幹平衡等身體素質，我們收集資料並配合多階層神經網路與遷移式學 習的神經網路設計，來克服現有開源資料難以標註脊椎的問題，此神經網路設 計為與一個 17 標註點的

預訓練神經網路堆疊後，以數千筆新收集的資料進行 訓練，如此我們可以得到新增的標註點，並且得到數萬筆舊資料的模型強健 性，為了搭載此神經網路並執行脊椎輔助檢測，我們設計了嵌入式系統進行神 經網路的推論，並以應用程式呈現人體姿態各角度的量測結果，針對嵌入式系 統，我們測試了 GPU 與 FPGA 兩著進行比較，嵌入式系統的使用使得使用者 電腦規格不受限制，可以更廣泛地使用，利用此系統，可以執行自動檢測脊椎 點、計算角度及醫療履歷的建置與儲存。
