The Child in the Electric Chair: The Execution of George Junius Stinney Jr. and the Making of a Tragedy in the American South

為了解決Electric switch的問題，作者Faber, Eli 這樣論述：

The tragic story of the killing of 14-year-old George Junius Stinney Jr., the youngest person executed in the United States during the twentieth centuryAt 7:30 a.m. on June 16, 1944, George Junius Stinney Jr. was escorted by four guards to the death chamber. Wearing socks but no shoes, the 14-yea

r-old Black boy walked with his Bible tucked under his arm. The guards strapped his slight, five-foot-one-inch frame into the electric chair. His small size made it difficult to affix the electrode to his right leg and the face mask, which was clearly too large, fell to the floor when the executione

r flipped the switch. That day, George Stinney became, and today remains, the youngest person executed in the United States during the twentieth century.How was it possible, even in Jim Crow South Carolina, for a child to be convicted, sentenced to death, and executed based on circumstantial evidenc

e in a trial that lasted only a few hours? Through extensive archival research and interviews with Stinney’s contemporaries--men and women alive today who still carry distinctive memories of the events that rocked the small town of Alcolu and the entire state--Eli Faber pieces together the chain of

events that led to this tragic injustice.The first book to fully explore the events leading to Stinney’s death, The Child in the Electric Chair offers a compelling narrative with a meticulously researched analysis of the world in which Stinney lived--the era of lynching, segregation, and racist assu

mptions about Black Americans. Faber explains how a systemically racist system, paired with the personal ambitions of powerful individuals, turned a blind eye to human decency and one of the basic tenets of the American legal system that individuals are innocent until proven guilty.As society contin

ues to grapple with the legacies of racial injustice, the story of George Stinney remains one that can teach us lessons about our collective past and present. By ably placing the Stinney case into a larger context, Faber reveals how this case is not just a travesty of justice locked in the era of th

e Jim Crow South but rather one that continues to resonate in our own time.A foreword is provided by Carol Berkin, Presidential Professor of History Emerita at Baruch College at the City University of New York and author of several books including Civil War Wives: The Lives and Times of Angelina Gri

消費者5G資費方案選擇性之分析研究

為了解決Electric switch的問題，作者古勝年 這樣論述：

在電信產業中世代的進步，已由4G進步到5G，擴展至今已普及5G基地建設。在各家電信業者投入大量資本在5G中，又在NCC建議下制訂出資費方案，對於提高消費者使用5G資費方案。本研究透過彙整相關文獻，挑選各大電信資費方案制訂對於消費者轉換5G意願，再進一步探討消費者轉換5G受何種負面的影響。 本論文採取Google問卷調查法，於2022年05月18日至2022年06月08日，以網路問卷進行問卷填答，總共回收有效樣本306份。本論文採用SPSS軟體進行驗證，由基本人口統計分析、信度分析、因素分析、相關分析，最後再將感知價值與基本人口統計兩者交叉分析，研究出T電信在轉換5G升級轉換程度上，大幅

領先各家電信。本研究進一步分析在各大電信修正行銷策略下，造成了感知犧牲只有微幅負面影響，有影響5G轉換意願不大，並且探討出網路速度及流量對於消費者使用意願都有正面影響。 最後，本論文將各種影響感知價值構面加以分析，給予建議給業者些許理論面和實際面的建議。

The Energy Switch: Transforming the Electrical Grid and the Future of Power

為了解決Electric switch的問題，作者Kelly-Detwiler, Peter 這樣論述：

Peter Kelly-Detwiler brings 30 years of experience in electricity generation and distribution to his current passion of helping transform the way we make and consume power. As Senior Vice President at Constellation, he oversaw creation of a virtual power plant, equal in size to the output of a large

nuclear plant, created by having customers turn off equipment during periods of extremely high electricity demand. Kelly-Detwiler has been engaged in competitive retail electricity markets from their earliest days in 1997, and rendered the first invoice in the retail industry. Kelly-Detwiler is a f

requent moderator and speaker at industry events concerning the interaction of power markets and emerging technologies and runs professional workshops on various related topics for executive and mid-level management. He contributes regularly to Forbes.com and other publications focusing on topics re

lated to disruptive innovation and the impact on the electric sector and society. He has written comprehensive research papers for clients on diverse topics relating to power markets and has been interviewed on public television and by USA Today, among other outlets.

改良型無刷直流馬達無感測驅動器研製

為了解決Electric switch的問題，作者陳仕軒 這樣論述：

本論文主要是研製一改良型無刷直流馬達無感測驅動器，本驅動器主要應用在車用無刷直流馬達風扇控制，輸入電壓範圍是10伏特~20伏特。本實驗控制核心是瑞薩電子公司RL78/F14數位訊號處理器R5F10PGG，用來實現無感測之馬達定位、啟動、驅動及保護等功能。為使無感測驅動器能達到可靠的啟動，在馬達開迴路啟動前藉判斷輸入電壓，給予所需的啟動參數。由實驗結果發現，模擬的霍爾訊號與原始霍爾訊號有角度誤差，因此使用軟體程式對落後訊號做相位超前補償。為使驅動波形在轉態時更加穩定，在相位未超前驅動波形轉態為相位超前驅動波形時，加入磁滯轉態銜接策略。最後針對馬達在驅動時若受到擾動，在軟體中設計保護判斷，經實驗

驗證能有效防止擾動造成的故障。
