  1. Very recently, schiller and muether at tubingen university suggested a new decomposition approach of the dbhf g matrix, and used to calculate the nucleon self - energy. they, sepa rate the g matrix into a bare nucleon - nucleon interaction v and correction term a g. the projection method is only applied to the correlation term a g, which is parameterized by four pseudo - mesons. then the nucleon self - energy in the dbhf can be calculated with the g matrix in the relativistic hartree - fock approximation

    裸相互作用部分，即單玻色子交換勢v對核子dirac自能結構的貢獻可以通過相對論hartree - fock方法得到，只把關聯部分用投影方法處理，並參數化為四種具有無窮大質量贗介子的交換，耦合常數與質量的比值是常數，從而關聯部分g對核子自能的貢獻也可以通過相對論hartree - fock方法求得。
  2. Doppler rate estimation method based on sub - space projection technique was proposed

    提出了一種基於子空間投影技術的多普勒調頻率估計方法。
  3. By studying the discrete fourier transform properties of the band - limited digital signal, the authors introduce alternating projection neural networks into the paper, expand apnn ' s application scope from real field to complex field, and present several important conclusions on apnn. analyzing and discussing network ' s tolerance to noise, convergence rate and the spectral leakage problem of the truncated signal expected to be extrapolated by using these conclusions, the paper presents an extrapolation algorithm for band - limited signals based on alternating projection neural networks. a lot of simulation experiments show that the algorithm is effective. in addition, the algorithm is also effective to spectrum extrapolation. owing to adopting network structure, the algorithm is prone to parallel computation and vlsi design, and consequently can satisfy real time military processing needs

    本文通過對頻帶受限數字信號的離散傅立葉變換特性的研究，引進了交替投影神經網路，並將其應用范圍從實數域拓廣到復數域，且給出了在復數域仍然成立的若干結論.運用這些結論，在對網路噪聲抑制、網路收斂速度及待外推信號因截斷而造成頻譜嚴重外泄問題的分析與討論的基礎上，提出了一種基於交替投影神經網路的外推演算法.模擬實驗表明該方法是行之有效的.另外，該演算法對頻譜外推同樣適用；由於它採用全互連神經網路結構，易於并行計算和vlsi實現，從而可滿足軍事上實時處理的需要
  4. We highlight the key points of this dissertation at the end of this charter. in chapter 2, a modified projection transformation method is presented, which utilizes preliminary estimation of interference doa. it is demonstrated that the side lobe performance of adapted antenna patterns can be significantly improved with this method and increased convergence rate of adaptive algorithm when the array manifold is not known exactly

    針對投影預變換在大信噪比時性能下降的缺點，提出了一種改進的基於投影預變換自適應波束形成演算法，通過對陣列協方差矩陣進行降維處理，既可抑制擾動誤差又可降低運算量，增強陣列的sinr輸出，具有良好的波束合成性能和較快收斂速度。
  5. The approximation property of projection pursuit wavelet neural network ( ppwnn ) which is applied to non - linear function is studied, the convergence rate is given in this paper also. 3. we demonstrate projection pursuit wavelet neural network ( wppnn ) has a good applicability by the approximation of five non - linear functions and the prediction of sunport and chaos time series and the use of edge detection
