This paper proposes a novel survival time pathway hunting method based on gene links. In the method, we incorporate gene link information for testing how significantly a pathway is associated with cancer patient's survival. Specifically, we establish a link-based Cox proportional hazard model (Link-Cox), in which two linked genes are considered together as a link variable and the association with...
Compared with traditional remote sensing, multiangular observation provides 3-D structural information of a forest through different directional observations. The MGeoSAIL model, suitable for multiangular observations, was developed based on the single-angle model GeoSAIL. The MGeoSAIL model combines the geometric-optic model with the radiation transfer model and has the advantages of both models...
In this paper, four new forecasting models ¨C univariate LS-SVM model and three hybrid models of ARIMA and LS-SVM models are introduced for wind power output forecasting. Historical data of 78 wind farms are used to compare and evaluate the performance of the best models. Empirical analysis indicates that the proposed univariate LS-SVM model and hybrid models can not significantly outperform linear...
Studying crop potential model system based on GIS and distributed computing architecture may effectively improve computational efficiency and enhance the independence of the model system. Firstly, the paper constructed crop output potential model system based on distributed computing architecture. Secondly, the paper designed the model system of crop output potential under network environment and...
A new model of software project risk management is presented, which uses the Bayesian networks to infer the probability of risk occurrence and the impact of risk simultaneously. The model can assess risks continuously and take proper measures to respond to risks during software project. Practice proves that by introducing this model into software development process, project risks can be well-managed...
The three-dimensional structure of bovine serum albumin (BSA) was obtained successfully with the homology modeling method. The reasonable results were presented: In the nine conservative areas, the desired Root-mean-square (Rms) value (0.0001) was obtained; 17 disulfides were added into the BSA successfully; In the loops construction, the score of loops was higher than 85 with composer module evaluation,...
This study develops a model for simulation of the behaviors of learners under the influence of motivation, engagement and intervention through application of cellular automata. It investigates the changing patterns of learners' behaviors when the three factors are assigned with different values individually. The results obtained show good agreement with the phenomenon generally being observed in practice.
In this paper, an adaptive model predictive control (MPC) weight coefficient methodology is proposed, and a stable output multi-variables zone(or range) control is implemented to guarantee the robustness of controlled process systems and the flexibility of manipulated variables. The weighted slack coefficients terms (WSCT) are added with nominal weight coefficients. The WSCT are adapted according...
In this paper, the virtual simulation system of power plant be developed on Web environment with the technologies of graphic model and virtual DCS. The system simulates the 600 MW coal-fueled power unit, distributed control system (DCS) of Foxboro I/A and digital electro hydraulic system (DEH) of GE XDPS. The initial data would be imported from real-time database (RTDB) of InStep eDNA. Designing concept,...
With regard to uncertain multi-criteria decision-making problems, in which the criteria values of alternatives are in the form of trapezoidal fuzzy numbers and the criteria weights are completely known, a prospect value function of trapezoidal fuzzy numbers based on risk attitudes of decision makers is defined, and the preference function in PROMETHEE method is replaced by the possibility degree of...
