[轉]效能測試:Windows 7 64 vs 32位元 誰比較快?
隨著Windows 7正式上市的腳步逼近,大家一定有些疑問:要安裝32位元的Windows 7就好,還是安裝64位元的?64位元真的在效能上領先32位元嗎?我有需要安裝64位元嗎?本文將進行Windows 7 32位元與64位元的效能測試,供讀者參考。
自從微軟發表64位元Windows XP後,每次發表新的作業系統,總會引起是否要安裝64位元的討論。理論上64位元可以帶來性能的提升,實際上要發揮64位元的優勢,必須要處理器、作業系統以及應用軟體等都支援64位元才行。

Classical control theory
今天與凌波討論到自動微調的系統, 找了一篇自動控制的理論, 說不定哪天有所頓悟
To avoid the problems of the open-loop controller, control theory introduces feedback. A closed-loop controller uses feedback to control states or outputs of a dynamical system. Its name comes from the information path in the system: process inputs (e.g. voltage applied to an electric motor) have an effect on the process outputs (e.g. velocity or torque of the motor), which is measured with sensors and processed by the controller; the result (the control signal) is used as input to the process, closing the loop.
