Ensemble methods use multiple classifiers to achieve better decisions than could be achieved using any of the constituent classifiers alone. However, both theoretical and experimental evidence have shown that very large ensembles are not necessarily superior, and small ensembles can often achieve better results. In this paper, we show how to combine a set of weak classifiers into a robust ensemble...
In-vivo three-dimensional (3D) DTI acquisition of an entire human heart for a complete cardiac cycle is currently technically impossible. We propose an alternative to this problem by simulating DTI of dynamic cardiac fiber structures. We first model a virtual dynamic cardiac fiber structure by integrating cardiac motion information into an ex vivo referential cardiac fiber structure and then use a...
In this paper, hierarchical holographic modeling (HHM) is used to identify the risks in transport PPPs under the perspectives of contractual nature of PPPs, institution and cultural environment, and inadequate supervision. Then, we propose that the traditional financial audit approach can not effectively control risk on PPPs, and furthermore, we give an analytic framework of audit supervision for...
The philosophy of SCM has been widely adopted by many companies to achieve the objective of long-term collaboration in the current increasingly competitive business environment. The role of collaboration between supply chain partners for improving the performance of inventory control is of special interest. This paper develops a single-vendor multiple-buyer integrated inventory model with the objective...
By synthesizing the literature from environmental and economics with that of entrepreneurship, we articulated a conception of environmental entrepreneurship, outlined the categorists of environmental entrepreneurship and pointed out environmental entrepreneurship is a good business model in low-carbon economy.
This paper reports an investigation of the emergence of a ratio-dependent predator-prey system with Hassell-Varley-type functional response and reaction diffusion. The instability of the uniform equilibrium of the model is discussed. The conditions for Hopf and Turing bifurcation are obtained in a spatial domain. Furthermore, spatial pattern formation is illustrated by means of numerical simulation,...
As the world is becoming increasingly urbanized, there are growing concerns on the urbanization. In this study, a common Cellular Automata (CA) model incorporating macroscaled contribution factors and an innovative acquisition method of the initial state was performed in Zhangjiagang Region to simulate the local urbanization development. Using Land Use Urbanization Level (LUUL) layer and recursive...
This paper utilizes Vensim version 5.8 to build the system dynamics simulation model of the inventory control in distributor system and makes comparison and analysis of the modelpsilas simulation outputs under different circumstances. We wish that all these simulations would provide scientific supports for enterprise management decision.
The novelty method is used for analyses and diagnoses of product line. The virtual design and modeling method are introduced through the real case. In simulation environment, it showed that there were some bottle-neck processes because of defective manufacturing technology. After produce line rebuilt in simulation, the average manufacturing technology time was about 41.2s. The utility ratio of machines...
Urban rail transit (URT) develops fast in China. Because its investment is enormous, its construction period is long and its influence is far-reaching. Therefore, it is important to analyze sustainable development of URT. The reasonable plan of URT is the key to setting up traffic transit system of sustainable development, one of the important tasks is to estimate scheduling of URT to ensure the science...
At present, the multivariate linear regression analysis was adopted in the biological toxicity forecast through establishment equation of the QSAR mostly, but the error forecasted was big in many situations because of the complexity and nonlinearity of structure-activity relationship, and it has a high request to the sample selection. In this paper forecast model of the nitrobenzene compound biological...
