國立陽明交通大學 機械工程系所 陳慶耀所指導 鄭力瑋的 三相電磁噴流之研究 (2021),提出 marine關鍵因素是什麼,來自於磁流體體力學(MHD)、勞倫茲力、多相流。

而第二篇論文國立陽明交通大學 電控工程研究所 蕭得聖所指導 陳瀚仲的 基於視覺伺服之七軸滾球與滑軌欠致動滑模控制器 (2021),提出因為有 欠致動器系統、滾球與滑軌系統、滑模控制、視覺伺服、機械手臂的重點而找出了 marine的解答。

三相電磁噴流之研究

為了解決 marine的問題,作者鄭力瑋 這樣論述:

摘要電磁噴流是一種運用磁流體力學(Magnetohydrodynamics, MHD)之概念,當給予電極板電能與固定磁場時,便可產生勞倫茲力,藉此推動導電流體。其優點在於致動原理簡易,且不需要依靠複雜的機械結構,便可實現推送之效果。常見的應用在微尺度之微動幫浦與大型船體無槳式推進器上,以往許多研究都著重在電場與磁場之設計與幾何構型的最佳化,而本研究透過實驗探討在電磁噴流中,電極板附帶產生電化學反應而生成氣泡所構成之多相噴流場。並藉由染劑與氣泡之方式發展一流場可視化之方法。本研究透過計算染劑之汙染面積並與數值模擬結果進行比較,發現在低電流時之預測流量結果較為相近。並定義一無因次參數為勞倫茲力雷

諾數(Re_L),用以描述電磁噴流之流場型態,實驗結果透過定性觀察當勞倫茲力雷諾數(Re_L)大於1600時,噴流型態會發展成紊流的型式。透過無因次分析結果也顯示其噴流擴散角(θ)與氣泡佔比(Ag)有隨Re_L數增加而有上升之趨勢,且在Re_L數大於1600後,因流場型態轉變,擴散角與氣泡佔比也有明顯上升之現象。在最後討論使用鋁電極板對於電磁噴流之影響。

Handbook of Air Quality and Climate Change

為了解決 marine的問題,作者 這樣論述:

This handbook covers the air quality/air pollution from the viewpoints of causing impacts on human/ecosystem health and climate change. Traditionally, air pollution has been a concern mainly in terms of its impacts on human health, and it is still an immediate public and governmental concern in most

Asian countries. However, in recent years so-called extreme weather events, such as stronger tropical cyclones, flooding, drought, and other phenomena, have been manifested causing tremendous losses of human lives and properties. Importantly, climate models tell us that such extreme weather events

are actually induced by anthropogenic global warming. It has been pointed out that mitigation or alleviation of such climate change leading to the extreme weather events in the next 30 years can be possible only by reducing air pollutants with positive radiative forcing such as ozone or methane, whi

ch are called short-lived climate pollutants (SLCPs). Here, concerns about mitigation of air pollutants from the points of human health and climate change have merged. This book covers different kinds of air pollutants and radiative forcers and how they can be measured. It also mentions the situatio

n of air pollutants in different continents and their regional impacts to human health, environment and economy as well as their link to extreme weather events. The book presents how the air pollution and climate change can be mitigated and how clean air technologies and international initiatives fo

r co-controlling air pollution and climate change have been developed. Dr. Hajime Akimoto received his B.S. in 1962 and Ph.D. in 1967 in physical chemistry from the Tokyo Institute of Technology. For his postdoctoral research he spent 3 years, 1969-1971, in the Department of Chemistry at the Unive

rsity of California, Riverside, and worked on the chemistry of photochemical air pollution. In 1974 he joined the National Institute for Environmental Studies in Tsukuba, Japan, as the head of the Atmospheric Chemistry Section in the Atmospheric Environment Division, and then served as the chief of

the Atmospheric Environment Division and Global Environment Division.Subsequently, Dr. Akimoto moved to the Research Center for Advanced Science and Technology at The University of Tokyo as a professor in 1993. In 2000, he joined the Frontier Research Center for Global Change, now under the Japan Ag

ency for Marine-Earth Science and Technology as the director of the Atmospheric Composition Research Program. After 2010 he served as director general of the Asia Center for Air Pollution Research in Niigata, Japan. Currently, he is a guest scientist at the National Institute for Environmental Studi

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 marine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。
