本研究主要在探討應用改良型順滑模態電流觀測器於無轉軸角度偵測元件永磁同步電動機驅動器之轉子角度估測。 一般而言,順滑模態觀測器是採用傳統正負號切換函數或是線性飽和切換函數。在此設計下,都必須採用低通濾波器以解決切跳的問題。本研究使用S型之切換函數來做設計,將可降低切跳之現象,增加轉子角度估測之精確度,也可免除因低通濾波器設計之需要所造成角度估測延遲。 模擬結果顯示出本研究設計之優點。更進一步,應用此理論於低成本16位元微控制器之實作,驗證了本方法之優越性與可行性。....

西元1918年第一次世界大戰結束,在戰爭中出現了以往都未出現的軍種與攻擊方式-空軍與毒氣攻擊。空軍的出現使戰場逐漸由前線延伸到後方的城市。毒氣的攻擊也使世界各國暴露在化學恐慌之下。為了因應此兩種變化,各國開始發展各種防空防毒措施,而範圍從都市規劃到防空壕的設計。 由於臺灣地處中國西南沿海,在西元1937年中日戰爭開打後,「臺灣總督府」就著手進行臺灣的防空設施的設置。在西元1941年12月7日日軍發動珍珠港事件,日本正式向同盟國宣戰。西元1943年6月4日日軍在中途島海戰遭受美軍的毀滅性攻擊,自此日軍戰略由主動轉為被動。在西元1944年10月20日菲律賓戰役爆發,美軍為了防範由臺灣進攻的飛機,因此大規模的轟炸臺灣,防空設施因而成為「臺灣總督府」重要的建設。 本論文主要以西元1937年至西元1945年為主要研究時間,在面對新型態的戰爭之下....

隨著智慧行動裝置的普及,行動服務相關的發展與應用已成為現今企業服務創新的契機。對顧客而言,行動點餐服務能提供快速取餐與不用排隊的優點。雖然先前多篇研究指出好的「知覺互動性」與「流暢體驗」會產生較高顧客滿意度,但鮮少研究聚焦於行動點餐服務領域。此外,遊戲化應用不僅提供顧客對服務的樂趣感受,且能增進顧客的互動知覺性與流暢體驗。基此,以行動點餐服務為例,本研究旨在探討遊戲化設計對「知覺互動性」、「流暢體驗」與「顧客滿意度」的影響。 本研究的執行概分為四大階段。第一階段為「探索與界定」階段,本研究先透過觀察法了解A速食餐飲業者之現行行動點餐服務內涵,並繪製出顧客旅程地圖。再者,本研究收集80份有效問卷,確認行動點餐服務之知覺互動性、流暢體驗與顧客滿意度衡量構面。接著,藉由訪談9位行動點餐服務重度使用者,發掘出22項行動點餐服務之激勵因子。第二....

United Nations, European Union and United States of America set up several environmental regulations in order to prevent our living environment from getting worst. Hence, firms are required to comply with these regulations in the production processes for reducing the environmental impacts. Although previous studies proposed frameworks and assessments enable to assist fi....

Finite element analyses were conducted to investigate the acceleration-amplified responses within geosynthetic-reinforced soil (GRS) structures. The focus of this thesis is on the influences of backfill soil and reinforcement parameters on the acceleration responses of GRS structures. Dynamic soil properties (i.e., shear modulus reduction and hysteretic damping) were co....
