基于曲线决策融合的SDN饱和攻击检测方法

针对软件定义网络(SDN)交换机和控制器的饱和攻击是SDN中的主要安全问题。在使用集成学习方法检测饱和攻击时,现有方法通常使用距离或熵值等简单的信息计算方法修正证据,可能存在信息丢失问题,降低饱和攻击检测精度。为解决上述问题,提出一种基于曲线决策融合的饱和攻击检测方法(SACOIN)。SACOIN首先计算多分类器概率矩阵的混乱程度修正多分类器内证据;随后将多分类器概率矩阵转换为曲线并去除噪声,提取重构小波的信号特征组成特征矩阵;然后计算特征矩阵行内互信息,基于上述互信息修正多分类器间证据;最后使用D-S证据理论融合修正证据,得到最终检测结果。实验结果表明,SACOIN在检测针对SDN交换机和控制器的饱和攻击时的准确率、精确率、召回率、F1值分别为92.3%、93%、92.1%、91.3%。

Robot’s Emotion Decision by Energy and Entropy Concepts

This study is to introduce concepts of energy and entropy to describe a robot＇s emoton decisien. It chooses the dimensional approach based on factors of pleasure and arousal for the merit of the interpolation between enotions. Especially, Circumplex model which has also two axes： pleasure and arousal is used. Besides, the model indicates how emotions are distributed in the two-dimensional plane. Then by the definition of psychodynamicsthe energy states （mental energy and physical energy） are matched to pleasure and arousal respectively that are the basis of Circumplex model. The mental energy is updated by the result of Prospect theory which measures the value of gain and loss as pleasure factor. And the physical energy is updated by the result of hedonic scaling which measures levels of arousal from pleasure computed by Prospect theory, and the result of intensity of stimuli. Then the energy states are fed by entropy. The feedback loop by entropy satisfies the 2nd law of thermodynamics. The energy states generated by stimuli and fed by entropy take a position in the plane of Circumplex model. Then distances between the current position and other emotions are cornputed to get a level of each emotion, proportional to the inverse of the distance.

Architectures in the Shadow of ＂Investors＇ Urban Planning＂--Case Study of Avala Hotel in Budva, Montenegro

Avala Hotel in Budva, Montenegro, has undergone three reconstructions. Each of them led to significant spatial changes. The first hotel established the foundation of urbanization process in Budva, the building was too high compared to the old town walls in the surrounding and thus not well integrated. The second reconstruction was the only successful achievement. At this time, in the first detailed urban plan including hotel and its surrounding area, the conclusion was that it represents ＂high-quality, seaside-favorable ambience＂ that should not be harmed by further building expansion. The last, illegal reconstruction in 2006 resulted in over enlarged new building disrespectful of the surrounding and the previous design. Similarly, the 2008 new detailed urban plan was the creation of ＂investors＇ urban planning＂. Entirely driven by profit, it arranges building reconstructions with multiple enlargements. This study tends to point out contextual impacts of the three hotels on the surrounding area, with special focus on the last reconstruction and ＂investors＇ urban planning＂ phenomena. The applied research method is comparative, chronological analysis of the three hotels. The aim of this research paper is to inspire initiatives that will help overcoming declining and harmful synergy of architecture and new socio-economic phenomena. It is the only way leading to the significant architectural goal： creating refined, harmonized and high quality ambience.
