Although the origins of the scientism genre can be traced to the writings of galileo and thomas huxley in centuries past, its modern incarnation began in the early 1970s with mathematician jacob bronowski ' s the ascent of man, took off in the 1980s with sagan ' s cosmos and hit pay dirt in the 1990s with hawking ' s a brief history of time, which spent a record 200 weeks on the sunday times of london ' s hardcover best - seller list and sold more than 10 million copies in 30 - plus languages worldwide
雖然科學主義之風可溯自數世紀前伽利略與赫胥黎的著述，但它到了現代卻又再度投胎轉世，從1970年初數學家布羅諾斯基《文明的躍升》開始，到1980年代薩根的《宇宙》一書使之起飛；而1990年代霍金的《時間簡史》更是挖到金礦，在英國《星期日泰晤士報》中，創下倫敦最暢銷精裝書排行榜蟬聯200周的紀錄，該書在全球以30多種語言發行，銷售逾1000萬本。Education, with its cycles of instruction so carefully worked out, punctuated by textbooks - - those purchasable wells of wisdom - what would civilization be like without its benefits
教育，以其教學周期如此精心地安排，並以教科書- -那些可以買到的智慧源泉- -予以強化，如果不受其惠，文明將會是個什麼樣子呢？And i shall no doubt feel somewhat vulnerable without the invaluable services of an astute secretary, particularly skilful in protecting me from annoying callers
當然還有我精明能幹的秘書，尤其她替我擋去一些無謂電話的本事。沒有她周到的安排，我的日子肯定會難過得多。As the traditional navigation system ca n ' t satisfy the requirements of the autonomous underwater vehicles ( auv ) navigation and position. we study a depthometer - doppler - aided strapdown inertial navigation system ( ddsins ) in combination of the developments of periodic navigation technique and some practical problem posed by the mathematical and variation of output data of doppler, furthermore, the digital simulation and semiphysica test are made to verify the validity of the algorithm, the main research work are as follows : design of the strapdown inertial navigation system of auv
由於傳統的導航系統很難滿足遠程水下航行器精確導航、定位的要求，本文在充分考慮使用特殊性的情況下，結合國內、外導航技術發展的實際狀況和發展方向，研究了水下航行器組合導航系統的誤差，重點解決了因多普勒輸出數據周期長和周期時變而給導航計算和濾波器設計帶來的問題，並進行了模擬和實物測試，模擬和實物測試結果表明本文所研究的設計方案合理，可以達到某型水下航行器導航、定位需要的精度。Traditional inertial mechanized - platform uses velocities to damp the system attitude to improve the precision of attitude, when the system acceleration is small. referring to the idea, this paper designeda damp kalman filter in strap - down attitude heading reference system ( ahrs ). the new method makes use of 3 - d accelerometer ' s measurements to estimate the system attitude, which is measured to compensate attitude errors. because the acceleration affected the precision of fiher directly, the fuzzy adaptive system was presented. the fuzzy logic inputs are three accelerations and the output is to control the measurement noise covariance matrix. simulations and experimental results prove that the damp algorithm can damp most of schuler oscillation and foucauh oscillation, so that to assure the filter convergence and efficiently improve the precision of strap - down ahrs
在系統機動性不強的情況下，傳統的平臺內阻尼演算法將系統本身的速度信息通過阻尼網路加到系統中，達到提高姿態角精度的目的.將這種平臺內阻尼的思想引入到捷聯慣性航姿系統中，在系統加速度較小的情況下，利用加速度計的輸出估計系統姿態角，通過卡爾曼濾波的形式補償系統姿態誤差.由於加速度的大小直接影響濾波器精度，本文設計了模糊自適應卡爾曼濾波演算法，根據三軸加速度計的輸出調整內阻尼量測誤差方差陣，從而避免了濾波器的發散.模擬和實驗驗證，內阻尼演算法可明顯抑制舒勒周期振蕩和傅科周期振蕩，避免了系統姿態漂移，有效提高了捷聯慣性航姿系統的精度The name copp comes from the particular probe scheme, chirps of packet pairs. a chirp of packet pairs is composed of several packet pairs with decremental inter - packet spacing
利用tcp的特殊語義並以報文周轉時間rtt代替單向延遲，可得到僅配置在發送端的capest ，其靈活性較好但精度明顯降低。At last, we study the fixed estimation statistics of navigation and positioning parameter, compare positioning accuracy of the condition estimation with that of the fixed estimation, and point out interrelation of them. 6 ) after investigating the two methods of increasing the success probability, a new method of increasing success probability is presented. based on the quality of ambiguity estimators, the new method carries out the ambiguity ordering process, chooses ambiguities by estimators " accuracy, and goes on ambiguity decorrelation process using those chosen ambiguities with high accuracy
6 ）研究了兩種提高整周模糊度估計成功概率的方法，提出了一種提高整周模糊度估計成功概率的方法，該方法是在模糊度去相關變換過程中，根據各個模糊度估計的質量，對模糊度估計元素進行排序選擇，選擇那些估計精度高的模糊度估計元素繼續進行模糊度去相關變換，通過數學分析和模擬證明了這樣的處理過程可以得到較大的成功概率。A shopkeeper, with red bruises on his cheeks about his nose, with an expression on his sleek face of quiet persistence in the pursuit of gain, came hurriedly and briskly up to the officer gesticulating
