Target distribution in cooperative combat is a difficult and emphases. We build up the optimization model according to the rule of fire distribution. We have researched on the optimization model with BOA. The BOA can estimate the joint probability distribution of the variables with Bayesian network, and the new candidate solutions also can be generated by the joint distribution. The simulation example verified that the method could be used to solve the complex question, the operation was quickly and the solution was best.

Endpoint Prediction of EAF Based on Multiple Support Vector Machines

引用

Journal of Iron and Steel Research International 2007年第2期14卷 20-24,29页

作者： YUAN Ping MAO zhi-zhong wang fu-li Key Laboratory of Process Industry Automation of Ministry of Education Northeastern University Shenyang 110004 Liaoning China

The endpoint parameters are very important to the process of EAF steel-making, but their on-line measurement is difficult. The soft sensor technology is widely used for the prediction of endpoint parameters. Based on the analysis of the smelting process of EAF and the advantages of support vector machines, a soft sensor model for predicting the endpoint parameters was built using multiple support vector machines （MSVM）. In this model, the input space was divided by subtractive clustering and a sub-model based on LS-SVM was built in each sub-space. To decrease the correlation among the sub-models and to improve the accuracy and robustness of the model, the sub- models were combined by Principal Components Regression. The accuracy of the soft sensor model is perfectly improved. The simulation result demonstrates the practicability and efficiency of the MSVM model for the endpoint prediction of EAF.

Hepatobiliary & Pancreatic Diseases International 2016年第2期15卷 125-130页

BACKGROUND： Some studies found that age at first birth is associated with pancreatic cancer; others did not. The present meta-analysis was to evaluate the relationship between age at first birth and pancreatic cancer in *** SOURCES： We searched Pub Med, Embase, and the Cochrane Library for relevant publications on age at first birth and pancreatic cancer up to April, 2014. The eligible studies（six cohorts and five case-controls） were independently selected by two authors. Pooled relative risk（RR） estimates and corresponding 95% confidence interval（95% CI） were calculated using the inverse-variance ***： The pooled RR of pancreatic cancer risk for the highest versus lowest categories of age at first birth was 1.21（95% CI： 1.01-1.45, P=0.314, I^2=13.7%）. Consistent relationships were also observed within subgroup analyses stratified by study design, geographic region, and whether the studies included adjustment for cigarette smoking, diabetes, or all of the confounders. In this meta-analysis, no publication bias among studies was observed using Egger＇s test（P=0.383） or Begg＇s test（P=0.436）.CONCLUSION： Our findings suggest that older age at first birth is associated with an increased risk of pancreatic cancer in women and the exact functional mechanism needs further investigation.

It remains a great challenge to understand the hydrates involved in phenomena in practical oil and gas systems. The adhesion forces between hydrate particles, between hydrate particles and pipe walls, and between hydrate particles and reservoir particles are essential factors that control the behaviors of clathrate hydrates in different applications. In this review, we summarize the typical micro-force measurement apparatus and methods utilized to study hydrate particle systems. In addition, the adhesion test results, the related understandings, and the applied numerical calculation models are systematically discussed.

We study the firing synchronization behavior of the inhomogeneous excitable media. Phase synchronizationof neuron firings is observed with increasing the coupling, while the phases of neurons are different (out-of-phase synchronization). We found the synchronization of bursts can be greatly enhanced by applying an external forcing (in-phasesynchronization). The external forcing can be either a periodic or just homogeneous thermal noise. The mechanismresponsible for this enhancement is *** numbers: 05.45.-a, 87.10.

Superhydrophobic surfaces have demonstrated exceptional efficacy in combatting biofouling contaminations of optical devices and equipment in marine applications. However, the fabrication of highly transparent superhydrophobic materials remains a formidable challenge due to the inherent trade-off between surface roughness for superhydrophobicity and optical ***, we design a robust and transparent superhydrophobic coating(Si-POSS) embedded silica nanoparticles(200 nm) with fluorinated polyhedral oligomeric silsesquioxanes(F-POSS) and zinc pyrithione(ZPT). The Si-POSS coating exhibits excellent water repellence toward diverse liquids and optical transmittance exceeding 90% in the visible spectrum. Moreover, the Si-POSS coating sustains long-term anti-bacterial(> 99.11%) and anti-algal effects for over 30 days, accompanied by mechanical,chemical, and thermal stability. This research asserts that the Si-POSS coating with outstanding combined characteristics holds significant potential for marine applications, particularly in self-cleaning and antifouling endeavors.
