為了解決Switch between A and的問題，作者Tuttle Studio 這樣論述：

PAPERBACK A5-Sized Journal: Standard A5 size (5.75 x 8.25 inches) allows for easily transporting in a handbag, backpack or tote. 144 DOTTED PAGES: Dotted grid pages give you the freedom to personalize your journaling experience. Are you an artist who wants to sketch? Are you a writer who wants to

journal? Do you like to switch between text and art? The dotted pages give you both--the space to draw and guidelines to take notes--allowing you to have a one-stop location for all your writing needs. INNER BACK POCKET: This paperback journal has a back pocket to offer a safe place to keep receip

ts, treasured notes or mementos. ACID-FREE PAPER: More difficult to decompose than regular paper and has a longer shelf-life. It is commonly used when someone wants to archive notes, daily journal entries or sketches for several years without the pages deteriorating or yellowing.FEATURED ART: Utag

awa Hiroshige was one of the most prominent Japanese ukiyo-e artists. He is best known for his series of prints The 53 Stations of the Tokaido (1832-1833). Hiroshige’s work influenced Europe’s Impressionists and Post-Impressionists, including Van Gogh and Monet.

改良型無刷直流馬達無感測驅動器研製

為了解決Switch between A and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。

Hiroshige Snow on MT Haruna Hardcover Journal: Dotted: 5 3/4 X 8 1/4, Ribbon Bookmark, 144 Pages, Acid-Free Paper

為了解決Switch between A and的問題，作者Tuttle Studio 這樣論述：

HARDCOVER, A5-Sized Journal: Standard A5 size (5.75 x 8.25 inches) allows for easily transporting in a handbag, backpack or tote. 144 DOTTED PAGES: Dotted grid pages give you the freedom to personalize your journaling experience. Are you an artist who wants to sketch? Are you a writer who wants

The dotted pages give you both--the space to draw and guidelines to take notes--allowing you to have a one-stop location for all your writing needs. RIBBON BOOKMARK: Whether you’re an avid writer or more spontaneous, a ribbon bookmark will help

keep track of where you left off writing, so that you don’t have to flip through pages to find your last entry. The use of a colorful ribbon also adds a more classic, sophisticated look to the journal and can withstand constant use versus a paper bookmark. ACID-FREE PAPER: More difficult to decomp

ose than regular paper and has a longer shelf-life. It is commonly used when someone wants to archive notes, daily journal entries or sketches for several years without the pages deteriorating or yellowing.FEATURED ART: Utagawa Hiroshige was one of the most prominent Japanese ukiyo-e artists.

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Switch between A and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。
