In this study, we aimed to establish a platinum-based chemotherapy response and toxicity prediction model in advanced non-small cell lung cancer (NSCLC) patients. 416 single nucleotide polymorphisms (SNPs) in 185 genes were genotyped, and their association with drug response and toxicity were estimated using logistic regression. Nine data mining techniques were employed to establish the prediction...
Subtractive clustering based methods have been well known for data clustering problems. However, Due to the computational demands of these approaches, clustering for large scale datasets such as spatiotemporal data and images have been slow to appear. A novel subtractive clustering method based on NystrÖm approximation is proposed. The contribution of proposed is a method that substantially reduces...
Currently, it's more and more important to share information and reference resource news for scientific researchers or managers to carried out collaborative research to some extent. In this paper, a service self-aware and resource adaptive-allocation architecture is proposed and demonstrated in scientific research system which can realize the flexible and controllable requirements. Self awareness...
This paper proposes a novel approach which combines empirical mode decomposition (EMD), short-time analysis and support vector machine (SVM) for text-independent speaker recognition. Short-time analysis is used for the result of empirical mode decomposition to extract speech features of speakers, and then the support vector machine are used for speaker recognition. Experiments demonstrate that the...
The demand of energy in rural areas is growing dramatically as well as the pressure of greenhouse gas (GHG) emission reduction. Therefore, rural low-carbon economy should be given more attention today because of the day-increasing energy consumption. Bio-energy is one of the low-carbon energies and has abundant biomass material in China's countryside, which means it should be a partial substitute...
Multi-signature is a mechanism which is more and more widely used in modern office system, especially in decision-making. However, no mature solutions were acknowledged or published openly by far. In this paper, we propose a novel solution for multi-signature handling, which is based on workflow resolution. Furthermore, we extend the Liaison workflow model by adding a new element, which marks signature...
The primary motivation of using Bayesian statistics in reliability analysis is the ability to incorporate prior knowledge with limited testing results in a formal procedure. This idea is particularly suitable for high reliable systems, which cannot afford enough samples to meet the confidence requirement in reliability demonstration test. The problem of appropriate choice of prior distribution is...
This paper addresses the orientation-workspace analysis of a special class of the Stewart-Gough manipulators. Based on half-angle transformation, a polynomial expression of thirteen degree representing the orientation-singularity locus of the manipulator at a fixed position is derived and examples are given to illustrate the result. Applying half-angle transformation and the inverse kinematics solution...
A new algorithm is proposed for settling the prediction of nonlinear time series. It makes use of the particularities of chaotic attractors and the relativities of unknown signals to reconstruct the phase space. Moreover, the algorithm is optimized and the concept of "near neighbor weighted distance" is imported to differentiate the Euclidian distance of every part of the near neighbor point...
The technical and economical index of traction substations are concerned with the reactive power and negative phase-sequence (nps) power. Set up of parallel reactive compensation (PRC) which have combined compensation effects for the reactive power and nps power is the key to the problem. PRC for the positive sequence reactive power of traction load is only related to the total compensating capacity,...
Blackouts of electric power often result in huge economic losses to power grid enterprises and society. To indicate the losses of accidents, this paper introduces the concept of the accident cost of distribution network failure, analyzes the various factors affecting it and figures out the calculation formula of it. On the basis of fuzzy theory, we use weight of power failure influence to describe...
This paper analyzes different bidding strategies of hydro-thermal suppliers, taking into account the changes of power demand and the unit's limits. In order to gain maximal profit, hydropower suppliers (except for cascade hydropower stations) are equivalent to thermo-power suppliers in this paper. And Nash equilibrium equations are proposed when different bidding parameters are selected to maximize...
In the circumstance of electricity market, it is very necessary for an electric utility to be clear about market distribution of residential energy consumption in future. with the data from Qinhuangdao electricity market investigation, Markov model with grey transfer probability matrix have been constructed on residential energy consumption items such as heating, cooking, cooling etc., we could do...
This paper mainly addresses the orientation-singularity and orientation capability analyses of the Stewart-Gough manipulator. Based on a particular kind of orientation representation of the manipulator, a polynomial expression of thirteen degree in the mobile platform orientation parameters is derived, which represents the orientation-singularity locus of the manipulator at a given position, and graphical...
This paper addresses the direct kinematics of a special class of the 6-6 SPS Stewart-Gough manipulators in which the moving and base platforms are two similar semisymmetrical hexagons. After proposing a mathematical model of the direct kinematic problem of this class of the Stewart-Gough manipulators, a multivariate polynomial equations set with respect to the moving platform position parameters and...
