Based on the “convexly separable” concept, we present a solid geometric theory and a new general framework to design piecewise linear classifiers for two arbitrarily complicated nonintersecting classes by using a “multiconlitron,” which is a union of multiple conlitrons that comprise a set of hyperplanes or linear functions(More)
According to the basic theory of wavelet, this paper used matlab software simulation to study image compression problem. Compared with traditional methods, it is more simple and effective.Wavelet image compression technology solves the contradiction of time and frequency domains localization which can not be achieved by the Fourier transform. For improving(More)
To handle the uncertain multiple attribute decision problem that the decision index value is hard to define accurately, this paper studies on the hybrid multi-attribute decision model of grey target when the index values are real number, interval number and triangular fuzzy number which exist together. According to the basic connotations of grey target(More)
Stevioside, a diterpene glycoside isolated from Stevia rebaudiana, has been reported to have anti-inflammatory properties. However, the underlying molecular mechanisms are not well understood. The objective of this study was to investigate the molecular mechanism of stevioside in modifying lipopolysaccharide (LPS)-induced signal pathways in RAW264.7 cells.(More)
Metabolomics, the systematic analysis of potential metabolites in a biological specimen, has been increasingly applied to discovering biomarkers, identifying perturbed pathways, measuring therapeutic targets, and discovering new drugs. By analyzing and verifying the significant difference in metabolic profiles and changes of metabolite biomarkers,(More)
This paper aims to review the development of scientific concepts of microecology and ecology of microbes and the role and functions of beneficial microorganisms in aquaculture and mariculture. Beneficial microorganisms play a great role in natural and man-made aquatic ecosystems based on the co-evolution theory in living biosphere on earth. Their functions(More)
This paper introduce the theory of convex hulls into the semi-supervised clustering, and through combining them, we come up with a new thought to the semi-supervise clustering. Then we verify the feasibility of the convex hull in the semi-supervised clustering through experiment which be carried in the two demensional space.
Mutations in the plasminogen activator inhibitor-1 (PAI-1) gene, along with increased PAI-1 levels, have been implicated in the pathogenesis of polycystic ovarian syndrome (PCOS). We investigated a possible influence of the promoter polymorphism (-844 A/G and -675 4G/5G) in the PAI-1 gene on plasma PAI-1 levels in 126 PCOS patients and 97 healthy controls.(More)
Conventional scrambling methods based on permuting pixels coordinates can be used to construct robust watermarkings which can endure erasing, cropping and compressing attacks. But most of these methods are used to scramble equilateral image, for the non equilateral image where its width not equal to its height, it is usually expanded into equilateral image(More)
A novel blind watermarking method for the 3D mesh model is proposed. This method is based on the geometry image which is created by the parameterization and sampling of the model. The geometry image except the boundary is partitioned into several sub-images of equal size. Every sub-image is normalized and decomposed with two-dimensional Haar wavelet. The(More)
