提高胱氨酸产率的工艺改进

研究了采用减压蒸馏出部分盐酸以提高胱氨酸收率的新方法，考查了酸水解、中和和脱色过程中一些工艺条件对胱氨酸生产的影响，并对部分反应机理做了探讨，使胱氨酸收率稳定在７％～８％。     

Shape classification based on singular value decomposition transform

In this paper, a new shape classification system based on singular value decomposition (SVD) transform using nearest neighbour classifier was proposed. The gray scale image of the shape object was converted into a black and white image. The squared Euclidean distance transform on binary image was applied to extract the boundary image of the shape. SVD transform features were extracted from the the boundary of the object shapes. In this paper, the proposed classification system based on SVD transform feature...     

Shape classification based on singular value decomposition transform

In this paper, a new shape classification system based on singular value decomposition (SVD) transform using nearest neighbour classifier was proposed. The gray scale image of the shape object was converted into a black and white image. The squared Euclidean distance transform on binary image was applied to extract the boundary image of the shape. SVD transform features were extracted from the the boundary of the object shapes. In this paper, the proposed classification system based on SVD transform feature extraction method was compared with classifier based on moment invariants using nearest neighbour classifier. The experimental results showed the advantage of our proposed classification system.
