In this paper, linear discriminant analysis (LDA) based on Lp-norm (LDA-Lp) optimization method is proposed. The objective function utilizing the Lp-norm with arbitrary p value is studied. By maximizing the Lp-norm-based ratio between the between-class scatter and the within-class scatter, LDA-Lp can construct a set of local optimal projection vectors. Moreover, the optimal projection vectors can...
Clinicians are very interested in researching what are important determinants of hospitalization for respiratory disease. In this paper, a general model to explain the relationship between the risk of respiratory disease and several meteorological variables will be presented by the framework of generalized additive models (GAMs) and its predictive effects will be evaluated. By using 9655 medical records...
Chronic diseases have gradually become the main factors affecting health. In order to estimate the prevalence and determine the risk factors among individuals, hospitalization survey data (n=54,536) from a county in central China in New Rural Cooperative Medical System (NCMS) were used in our study. In this paper, χ2 test and non-conditional logistic regression analysis were the key models to analyze...
The cloud model is a mathematical representation to fuzziness and randomness in linguistic concepts, and integrates the fuzziness and randomness of a linguistic concept in a unified way. This model is a new method for transformation between qualitative and quantitative in the knowledge. In this paper, through analysis of the output of the nonlinear characteristics of PV cells the cloud model will...
OWL originated in the W3C, is known as a Web ontology language for descriptions. Since February 10, 2004, OWL has been officially recommended as a W3C standard. OWL has the describe logic as the logic-based theory, in the syntax and semantics are integrated to the construction thinking of describe logic. OWL reasoning tools are currently the OWL ontology knowledge base into description logic reasoning.
Two low-temperature PCBs (polychlorinated biphenyls) -degrading strains were isolated from the long-term PCBs-contaminated soil and named strain P and strain Q which could utilize the PCBs as the sole carbon source and energy source. These two strains were identified by 16S rDNA sequence analysis. PCBs-degrading ability of these two strains was investigated by resting cell experiment and the bioremediation...
An RFID authentication scheme based on ring signature was proposed. The Tag and back-end database were properly configured with different workloads, aiming to ensure the Tag's privacy and realize the authentication. This scheme only needed two bilinear pairing computations for any group size in the back-end database and no computation in Tag in order to enhance the network efficiency, which was suitable...
TCP now is widely used in Transmission Control Protocol; however, in the wireless network environment, TCP congestion control typically has some defects such as high-error rate, long-latency, low-bandwidth and frequent-movement, etc. In the wireless network, the implementation difficulty of congestion control mechanism is the degree of congestion, which is not only relevant to the length of the queue,...
The issue of data updating is the most important issue facing organizations deploying real-time data warehouse solutions. This paper discussed the real-time data warehouse implement method, proposed feasible real-time data warehouse architecture based on SOA. This SOA based real-time data warehouse architecture uses the Web service to pack the various source database systems, and the various changed...
Grid is a 'virtual supercomputer' which combines the resources distributed in different palaces through the network. Aiming at the continual increase of grid resource, and on the basis of comparative analysis of the resource discovery mechanism of the existing networking, a mixed resource discovery model, which combines the distributing and centralizing mechanism together, is proposed in this paper...
