It can be boiled down to combinatorial optimization problem in mathematics. on the basis of summarizing the complexity and structural features of hmb and rules of its design and manufacture and analyzing the spatial relationship in 3d layout of hmb, the expressions of relevant variants are put forward using the object - oriented approach
在全面總結液壓集成塊設計問題的復雜性特點,以及集成塊類零部件的結構特徵和設計、製造信息組成規律的基礎上,本文深入分析了集成塊立體布局的空間關系,用面向對象方法定義了與該問題有關的特徵變量的示性表達式,給出優化目標和約束條件,進而確立了集成塊設計問題的數學優化模型。In the control software, the object - oriented method is used for doing system analysis and study. furthermore, the message - driven mechanism is used in the control software research and design. the instantaneous zero vector inserting space vector pwm theory is adopted to control the permanent magnet synchronous machine as the driver motor in the control software
軟體採用面向對象的程序設計方法對系統進行分析與研究,將消息驅動機制應用於控制軟體的設計和開發之中,在控制軟體中採用瞬時零矢量插入磁鏈軌跡法(電壓空間矢量法)來控制永磁同步電機。The 00 ( object - oriented ) technique of standard template library with ansi / iso c + + is used in designing the program, and the dynamic access mechanism and the startup with zero content are realized by using the specialization and inheritance object of vector template class as the data container which can change the content itself according to the number of discretization node data of a computing practicality. so, the fact that the use of the static ems memory which is not necessary is avoided
在設計面向對象有限元程序中運用了基於ansi isoc + +標準模板庫( stl )的技術,以向量模板類的特化繼承對象為變容量數據容器,實現了可按計算實例的離散結點數量動態存取數據的機制和數據容器的零容量啟動,從而避免了運算時系統對靜態內存空間的超量佔用。This paper introduces the methods of hyperspectral images band selection based on the property of hyperspectral remote sensing images, utilizes the projection pursuit approach to find optimal solutions for a selected projection index based on dynamical evolutionary algorithm and then project a high dimensional data set into a low dimensional data space to produce a sequence of projection images, explores zero - detection method to threshold projection images to detect anomaly tar get
摘要運用基於波段間相關性的高光譜影像波段選取方法進行波段的預選取,採用投影尋蹤的方法在動力演化演算法的基礎上尋找最佳投影方向,將高維數據投影至低維數據空間,在各投影分量圖像上採用零點檢測閾值化的方法進行異常目標的提取。In the second part, we investigate the compact submanifolds m with the parallel isoperimetric section in the real space forms rm ( c ) and prove that if there exists a parallel isoperimetric section on m, and the sectional curvature of m is always greater than zero, then m is contained in a hyper - sphere ; and get that the gauss curvature of the compact surfaces m with constant mean curvature in constant curvature space r4 ( c ) is always greater than zero, then m is a totally geodesic surface or a sphere, where an isoperimetric on m means a unit normal vector field defined globally on m with m1 ( ) = constant
( 2 )研究了實空間形式r ~ m ( c )中具有平行等參截面的緊致子流形m ,證明了具有一平行等參截面的子流形m ,如果m的截面曲率恆正,則m包含在r ~ m ( c )的一個超球面內;對于常曲率空間及r ~ 4 ( c )中具有常平均曲率的緊致曲面m ,如果m的高斯曲率處處大於零,則m或為r ~ m ( c )中的全測地曲面或為一球面。這里m上的等參截面是m上整體定義的單位法向量場,使得m關於它的平均曲率m _ 1 ( )是常數。Hence, the transformation matrix composed with the eigenvectors corresponding to the largest eigenvalues of the transferred between - class scatter can maximize the fisher criteria
然後在這個零空間里,尋找對應于樣本類間離散度矩陣的較大特徵值的特徵向量作為最終降維的轉換矩陣。分享友人
