National Geographic Readers: Animal Tails (L1/Co-Reader)

為了解決Have a ball的問題，作者Davidson, Rose 這樣論述：

Why do animals have tails? Parents and kids together will discover unique animals and learn all the cool ways their tails help them move, communicate, and keep safe. This Level 1 Co-Reader takes readers around the world to meet some kid-favorite and new creatures whose tails have remarkable abili

ties. Learn how dolphins use their powerful fins to swim up the Amazon River, why a pangolin uses its scaly tail to curl into a ball, and how a mom and baby spider monkey swing from tree to tree with a fluffy long tail! Each page will dazzle and delight with new and familiar creatures and amazing fa

cts. Fun activity pages allow parents and kids to engage with the content even more while also building their vocabulary. National Geographic Kids Readers have been a hit in the beginning reader category, and this book builds upon that success with a different approach--parents and children reading

together. With the same combination of careful text, brilliant photographs, and fun approach to high-interest subjects that has proved to be a winning formula with kids, National Geographic Co-readers provide one page of adult read-aloud and one page of kid read-aloud text on each spread, building t

oward a collaborative reading experience. So come along for a tale of animal tails and learn what makes them so special!

基於視覺伺服之七軸滾球與滑軌欠致動滑模控制器

為了解決Have a ball的問題，作者陳瀚仲 這樣論述：

隨著欠致動器系統的發展增長，許多欠致動器系統控制法則被提出，相關研究成為一個熱門的議題。為了研究欠致動器，本研究在實驗室中以上銀六軸機械手臂RA605、滑軌與金屬球建構了一個七軸的欠致動器系統，目的為控制在滑軌上自由滾動的金屬球的軌跡。在控制器上我們選擇使用有效消除系統不確定項與外擾的滑模控制器，並定義虛擬控制訊號來控制缺乏致動器的金屬球。透過增益矩陣的設計，可指定當系統狀態落在滑動平面後的特徵值，讓整體系統沿著期望軌跡前進時皆能有相同的響應。最後本研究設計了靜態與動態兩條路徑，在靜態路徑中測試控制器對於步階輸入的過衝與響應速度，在動態路徑中測試控制器對於持續變動金屬球軌跡的追跡效能。而滾球

與滑軌系統中，本研究使用高速相機陣列，以與機械手臂相同的1000fps取樣速度來抓取金屬球位置，同時搭配嵌入式板子進行影像處理。將影像資訊搭配卡爾曼濾波器來估測位置，降低整體的觀測誤差，並在滑軌兩側裝設額外的標記，以此來校正金屬球的位置，最後達到極小的觀測誤差。

為了解決Have a ball的問題，作者Hamada, Megumi 這樣論述：

An increasingly popular approach to second and foreign language education, this book focuses on incidental learning: how students learn words from reading. Despite its popularity, some researchers have questioned this theory that students can learn new words by inferring meanings based on a text the

y are reading. So, why does the incidental method not work for some students? What are the conditions for naturalistic learning to occur? What do students need to be able to do while reading in order to learn words successfully? Tackling these questions head-on, this book provides researchers and ed

ucators with a more specific account of the processes behind the seemingly naturalistic method. Clarifying the connection between reading and word learning processes, Megumi Hamada proposes a new model, the Cognitive Model of Word-Meaning Inference, to describe how we obtain and use word-form and co

ntextual information for learning words and the pedagogical applications of this. A significant new contribution to research in the field, Learning Words from Reading provides a cognitive perspective on how students learn new words from reading in a second or foreign language. Megumi Hamada is Pro

fessor of English in the TESOL and Linguistics programs at Ball State University, USA.

龍洞灣潛水活動與漁業利用協調之研究

為了解決Have a ball的問題，作者余又芪 這樣論述：

沿岸海域利用日趨多元化，海洋遊憩活動發展正方興未艾，自然與長期在此捕魚的沿岸漁業產生衝突，基於國民均可利用海洋的原則，先來後到互相尊重下方可善用海洋。本研究針對東北角龍洞灣潛水活動與沿岸漁業之用海衝突及其因應解決之道進行剖析，並參考日本之作法，最後提出具體建議。結果盼能對雙方之持續發展有所貢獻。研究結果摘下如下:一、龍洞灣是天然港灣，擁有很好的海洋生態環境與地理特性，故水域遊憩活動眾多，亦是離北部最近的潛水熱點，假日人滿為患。二、水域遊憩管理辦法對於潛水活動之相關必備條件與要求，對於潛水者及載客之船長或駕駛人均有明文規定，重點在於強調保障潛水者之安全。三、龍洞灣附近漁業資源豐富，主要漁業有底

延繩釣，棒受網，流刺網與一支釣，其漁業在貢寮地區僅次於澳底漁港，對該地區的經濟發展有一定的貢獻。四、日本沿岸海域利用之沿革由早期的純為漁業利用，直到1980年代開始至近年來逐漸加入了娛樂漁業(遊漁)、海洋遊憩活動、離岸風電等，沿岸帶的綜合管理與利用者之間協調和諧利用亦成為刻不容緩的問題，此種發展過程與台灣類似。五、海洋遊憩活動與漁業及娛樂漁業之糾葛問題有(一)漁業:妨害漁業、妨害航行、破壞漁具漁網。(二)海洋遊憩活動:妨害練習、妨害競賽、限制活動區域、接觸漁具漁網。(三)娛樂漁業:妨害釣具、破壞釣具、妨害航行、魚類逃脫。六、日本有關潛水活動與漁業之協調重點為:1.潛水協會與漁會簽訂協定約束雙方

之權利義務、2.指定潛水區域、3.限制潛水時間與期間、4.設置告示牌與重視環保等。七、潛水活動與沿岸漁業的衝突主要分為空間與資源上之衝突，其中空間利用的衝突為活動範圍與規避航道之衝突；資源利用的衝突為棲地環境之破壞與海洋生物資源之競合。八、潛水活動與沿岸漁業衝突之因應對策: (一)成立雙方協商機制與管理機制、(二)漁港朝多元利用、(三)加強安全與環保宣導並落實違規取締、(四)航道範圍加浮球標誌。關鍵字：海洋遊憩活動、龍洞灣、水域遊憩管理、潛水活動、娛樂漁業、沿岸漁業
