A study of constraints on the constitutive relationships of electromagnetic medium based on generally acknowledged truths

The study of constraints on the constitutive relationships of electromagnetic media is of great importance in the aspects of the medium characteristics analysis, the new article material synthesis and the medium parameters reconstruction, etc. According to the fact that the constitutive relationships should not conflict with the general physical laws, the constraints that the constitutive relationships of electromagnetic medium must satisfy have been summarized in this paper. These constraints include determinacy principle, objectivity principle, causality principle and permission principle. And the parameter constraints of the arbitrary linear homogenous time-invariant medium are obtained following the minimum energy consumption principle. This work provides a new way of ascertaining the constitutive relationships of the electromagnetic medium.

The History, Trend, Types, and Mitigation of Distributed Denial of Service Attacks

Over time, the world has transformed digitally and there is total dependence on the internet. Many more gadgets are continuously interconnected in the internet ecosystem. This fact has made the Internet a global information source for every being. Despite all this, attacker knowledge by cybercriminals has advanced and resulted in different attack methodologies on the internet and its data stores.

These kinds of attacks remain the most effective methods used by the bad guys to cause substantial damage in terms of operational, reputational, and financial damage to organizations globally. These kinds of attacks have hindered network performance and availability. The victim’s network is flooded with massive illegal traffic hence, denying genuine traffic from passing through for authorized users. The paper will explore detection mechanisms, and mitigation techniques for this network threat.

交换式以太网中连续实时流媒体的可靠组播

对目前局域网中连续实时流媒体的可靠组播进行了研究.首先分析了局域网影响可靠组播的几个特性,然后设计了局域网内针对连续实时流媒体的基于重传的可靠组播传输协议.协议中的错误恢复首先利用接收者检测包丢失,同时采用NAK(negative acknowledgment)抑制减少产生的反馈包;然后发送者根据NAK请求重传已经丢失的数据包;接收者根据本地播放时间限制决定接收或者丢弃迟到的重传包.实验结果和性能分析证明了该可靠组播协议的可靠性和有效性.

Cognition-Based Interactive Phases and Strategies in Teaching Academic Reading

Academic English reading requires deeper cognitive involvement in addition to language proficiency and plays a vital role in moulding a critical mindset. However, cognitive progress is seldom targeted in classroom teaching. This study proposed a teaching method of three reading phases in terms of cognitive mechanism and communicative teaching approach.Ninety university freshmen of non-English major participated in the study, who were taking the course of Academic English Reading in the 2nd semester. The data were collected from self-report Research Skills Assessment twice and semi-structured interview, and analyzed with paired sample t test and Pearson correlation. The results showed that 1） “critical thinking”, “organizing ideas”, and “finding information” were believed to improve significantly at the end of the course; 2） reading skill was associated with writing skill and the sense of “big picture” in self perception; 3） the cognition-based interactive reading instruction was acknowledged to be conducive to academic reading. It complements Academic English reading pedagogy by juxtaposing the need for both individual cognition and group interaction in classroom teaching.
