Singular value vecto r of an image is a valid feature for identification. But the recognition rate is low when only one scale singular value vector is used for face recognition. An algorithm was developed to improve the recognition rate. Many subimages are obtained when the face image is divided in different scales, with all singular values of each subimage… (More)
With the advancement of distributed sensing technologies, abundant data are generated in rolling processes. While these data contain rich information about the process and product, it is a challenging task to develop a systematic method to model the relationship between process and product quality variables for quality improvements. This paper addresses… (More)
Metamorphic malware is able to change its signature which is a fixed sequence of bytes or code from generation to generation. This makes the traditional scanner based on the signature difficult to detect it. Combing normalization with traditional scanner is a promising direction to solve the problem. The idea is: firstly transform the code into canonical… (More)
Spectral clustering algorithm has proved be more effective than most traditional algorithms in finding clusters. However, its high computational complexity limits its effect in actual application. This paper combines the spectral clustering with MapReduce, through evaluation of sparse matrix eigenvalue and computation of distributed cluster, puts forward… (More)
Reconfigurable assembly systems enable a family of products to be assembled in a single system by adjusting and reconfiguring fixtures according to each product. The sharing of fixtures among different products impacts their robustness to fixture variation due to trade offs in fixture design (to allow the accommodation of the family in the single system)… (More)
In this paper, a new matrix based on dimensional transformation is used to present a image,and then a set of efficient image features are extracted by using SVD algorithm. Through Theory analysis and experiment results, the method has well stability to have broad application and high efficient recognition rate.
Hair cells in posthatch chickens regenerate spontaneously through mitosis or the transdifferentiation of supporting cells in response to antibiotic injury. However, how embryonic chicken cochleae respond to antibiotic treatment remains unknown. This study is the first to indicate that unlike hair cells in posthatch chickens, the auditory epithelium was free… (More)
