Segregation Made Them Neighbors: An Archaeology of Racialization in Boise, Idaho

為了解決Prevent from的問題，作者White, William a. 這樣論述：

Segregation Made Them Neighbors investigates the relationship between whiteness and nonwhiteness through the lenses of landscapes and material culture. William A. White III uses data collected from a public archaeology and digital humanities project conducted in the River Street neighborhood in B

oise, Idaho, to investigate the mechanisms used to divide local populations into racial categories. The River Street Neighborhood was a multiracial, multiethnic enclave in Boise that was inhabited by African American, European American, and Basque residents. Building on theoretical concepts from whi

teness studies and critical race theory, this volume also explores the ways Boise’s residents crafted segregated landscapes between the 1890s and 1960s to establish white and nonwhite geographies. White describes how housing, urban infrastructure, ethnicity, race, and employment served to delineate

the River Street neighborhood into a nonwhite space, an activity that resulted in larger repercussions for other Boiseans. Using material culture excavated from the neighborhood, White describes how residents used mass produced products to assert their humanity and subvert racial memes. By describ

ing the effects of racial discrimination, real-estate redlining, and urban renewal on the preservation of historic properties in the River Street neighborhood, Segregation Made Them Neighbors illustrates the symbiotic mechanisms that also prevent equity and representation through historic preservati

on in other cities in the American West.

改良型無刷直流馬達無感測驅動器研製

為了解決Prevent from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。
