運動訓練與停止訓練對中老年人骨骼肌氧合能力與身體功能表現之影響
為了解決Nyquist frequency 的問題,作者杨永 這樣論述:
運動是一種改善中老年人骨骼肌氧合能力、提高肌肉力量並最終影響整體身體功能表現的有效方式。然而,較少的研究評估不同運動類型之間訓練效益的差異。此外,由於中老年人生病、外出旅行與照顧兒童等原因,迫使運動鍛煉的中斷。如何合理安排運動訓練的週期、強度與停訓週期,以促使中老年人在未來再訓練快速恢復以往訓練效益,目前亦尚不清楚。本文以三個研究建構而成。研究I:不同運動訓練模式對中老年人的骨骼肌氧合能力、肌力與身體功能表現的影響。以此探討50歲及以上中老年人進行每週2次為期8週的爆發力、阻力訓練以及心肺訓練在改善中老年人肌肉組織氧合能力、與肌肉力量身體功能效益的差異。我們的研究結果表明:爆發力組在改善下肢
肌力、最大爆發力與肌肉品質方面表現出較佳的效果。心肺組提高了30s坐站測試成績並減少了肌肉耗氧量,從而改善了中老年人在30s坐站測試期間的運動經濟性。年紀較高的肌力組則對於改善平衡能力更加有效。此外,三組運動形式均有效改善了中老年人人敏捷性。研究 Ⅱ:停止訓練對運動訓練後中老年人肌力與身體功能表現的影響:系統性回顧與meta分析。本研究欲探討停止訓練對運動訓練後中老年人肌力與身體功能表現訓練效益維持的影響。我們的研究結果表明:訓練期大於停止運動訓練期是肌力維持的重要因素。若訓練期

一個十位元每秒兩千萬次取樣帶冗餘位逐漸趨近式類比數位轉換器
為了解決Nyquist frequency 的問題,作者徐志豪 這樣論述:
如今電子產品除了要效能好,亦追求低功耗與輕薄短小,由於半導體製程技術的進步,帶動了積體電路設計的成長,許多低功耗的晶片得以實現,在眾多類比數位轉換器中,逐漸趨近式(Successive-Approximation)由於大部分元件皆由數位邏輯電路所構成,且整個電路僅需一組比較器即可,大幅地降低了資料轉換所需的功耗。本論文完整製作一個10-bit 20MS/s SAR ADC,架構採用分段式電容陣列數位類比轉換器,使用TSMC 0.18um 1P6M CMOS製程,電源供應1.8V,輸入頻率為1.97265625MHz進行模擬,訊號雜訊與失真比(SNDR) 60.71 dB,有效位元數(ENOB
) 9.79-bit,功耗0.92 mW,品質因數(FOM) 52f J/conversion-step,核心晶片佈局面積0.31*0.21〖mm〗^2,晶片總佈局面積1.163*1.169〖mm〗^2。最後設計規格同樣為10-bit 20MS/s SAR ADC,架構改成帶冗餘位演算法,將MSB電容拆解並分配至原電容陣列中,達到電容切換速度的提升,並在栓鎖電路前加上一級前置放大器,用以降低誤差,提高比較器的精準度。使用相同製程與輸入頻率進行模擬,訊號雜訊與失真比(SNDR) 61.93 dB,有效位元數(ENOB) 9.99-bit,功耗3.024mW,品質因數(FOM) 148.7f J/
