  1. From the paper it is found that this technique of proper orthogonal decomposition not only enhances our understanding of the underlying physics of wind loads and their effects on structures, but also provides efficient means to estimate structural response under multi - correlated excitations

    從本文可以看出pod方法不僅可以提高我們對風荷載及其對建築物作用的認識，同時提供了一種有效的分析多激勵響應的方法。
  2. However, the simulated annealing algorithm will expand too much time to estimate the values of objective function when applied to aerodynamics optimizations. the way to remedy this problem in this dissertation is by improving the efficiency of optimizer and the cfd - solver. our cfd - solver is base on the modification to the proper orthogonal decomposition ( pod ) method that can produce a finite series of basis functions or modes through the solution of snapshots

    但對于氣動外形優化設計問題來說，由於評估需要解決的問題的目標函數值需要多次調用流場解算器，會導致用模擬退火演算法進行優化設計的計算工作量過大，因此需要我們對流場解算器和優化方法兩個方面進行研究以尋找此問題的解決辦法。
  3. The simulation results show the validity of this algorithm. 2. a novel 2 - d esprit method based on three orthogonal linear arrays is proposed to estimate 2 - d doa of different users

    提出了一種新的基於垂直陣列結構的二維capon 、 music和esprit方法來估計信號的doa ，此方法只需三個均勻直線陣就可估計用戶的二維doa 。
  4. Because of enabling to provide high - rate and high - quality wireless and mobile communication service, orthogonal frequency division multiplexing ( ofdm ) system is becoming a very hot research topic recently, and it is especially one of the technical difficulties to estimate and equalize the time - varying ( tv ) dispersive channels

    在移動無線通信中，由於能提供高速率和高質量的通信服務，正交頻分復用（ ofdm ）技術成為當前國際上的研究熱點，而時變色散通道的估計和均衡問題是其中的技術難點之一。
  5. We can apply many good qualities of wavelet orthogonal series to estimate the condition probability density function of hmm ' s

    我們利用小波正交級數的很多良好性質來估計隱馬爾科夫模型中的條件概率密度函數。
  6. Fifthly, using uniformly orthogonal design theory to arrange the four - lever temperatures and four - lever vibration stress, catch an excellent accelerated life text plan, which make the estimate value have the well precision in normal stress lever, at the same time that can reduce the sample number and shorten the test time

    第五，運用均勻正交設計對環境溫度和振動應力的四個應力水平值進行合理搭配，得到一組較優的加速壽命試驗方案，在減少樣本數量、縮短試驗時間的同時使產品在正常應力水平的壽命估計值具有較高的精度。
