试论地下式箱变的特点及其应用

传统的箱式变电站很难与周围的环境协调,许多发达国家已按照城市生态设计理念,逐步将变压器埋入地下安装,地下式箱变应运而生,介绍了新一代地下式箱变的结构特点与优点及其推广应用前景。     

恶意软件检测中解决样本不平衡问题的策略

互联网技术已经使人们的生活和工作发生了巨大的改变．然而,人们在享受互联网提供的便利的同时,也承受着恶意程序带来的威胁．在数字化时代的今天,与恶意程序的对抗已成为信息领域的焦点．由于恶意软件检测中的恶意软件样本难于获取,同时,标记大量的样本也需要花费大量的人力和物力,所获得的恶意软件样本远远少于正常软件样本,因此各类的训练样本之间存在分布不平衡的分类问题．为了解决该问题,本文提出采用SMOTE过采样方法,通过合理的增加少数类样本来解决样本不平衡问题．     

基于粗糙集的多源数据库缓存冲突自动处理方法

In order to improve the ability of multi-source database cache conflict adjustment, a multi-source database cache conflict automatic processing method based on rough set is proposed. The multi-source database cache data channeling model is constructed, the load balance scheduling method is used to balance the multi-source database cache, the multi-source database cache data feature mining is carried out with the fuzzy rough set feature extraction method, and the rough set features of multi-source database cache data are extracted. The multi-source database cache conflict is adjusted adaptively by multiple information reorganization and big data information fusion method. Through the distributed attributes of rough set, the cache conflict of multi-source database can be handled automatically. The simulation results show that the multi-source database cache has better equalization configuration ability, reduces the risk of data congestion, the number of rounds of conflict and the number of dead nodes, and improves the balance and security of multi-source database cache.
