运用双网隔离技术打造内外网新模式

为满足干部在上内部网络的同时,也能方便地访问互联网(下称外网),浙江省淳安县财税局经过跟踪测试后,选定一款为主其它为辅的隔离卡和双网隔离机,能简捷稳定地实现内外网的切换,为行政机关单位解决上外网问题提供了一种新模式。     

基于前后向迭代法的3维标量激光漫反射特性

 针对激光点对点通信方式的不足,提出了利用海面作为激光漫反射媒介进行组网通信的设想,并对激光入射理想导体表面后产生的散射场进行了的研究。首先利用3维标量锥形波对入射激光束进行了模拟;然后列出了积分方程,并根据矩量法进行了离散;最后通过前后向迭代法求解矩阵方程,得出了3维散射系数,准确地表示了基于理想导体界面的3维标量激光漫反射特性。     

Improved AFEM algorithm for bioluminescence tomography based on dual-mesh alternation strategy

Adaptive finite element method (AFEM) is broadly adopted to recover the internal source in biological tissues. In this letter, a novel dual-mesh alternation strategy (dual-mesh AFEM) is developed for biolumi- nescence tomography. By comprehensively considering the error estimation of the finite element method solution on each mesh, two different adaptive strategies based on the error indicator of the reconstructed source and the photon flux density are used alternately in the process. Combined with the constantly adjusted permissible region in the adaptive process, the new algorithm can achieve a more accurate source location compared with the AFEM in the previous experiments.
