It aims to solve some of the problems associated with IP networks, increasing content distribution capability and improving users' experience. To analyse the requests' patterns and fully utilize the universal cached contents, a novel intelligent resources management system is proposed, which enables effi cient cache resource allocation in real time, based on changing user demand patterns. The system is composed of two parts. The fi rst part is a fi ne-grain traffi c estimation algorithm called Temporal Poisson traffi c prediction(TP2) that aims at analysing the traffi c pattern(or aggregated user requests' demands) for different contents. The second part is a collaborative cache placement algorithm that is based on traffic estimated by TP2. The experimental results show that TP2 has better performance than other comparable traffi c prediction algorithms and the proposed intelligent system can increase the utilization of cache resources and improve the network capacity.展开更多

They focused on the relation between ethics and two main contexts： education and research. This paper aims at discussing what ethical procedures were taken in international studies. The data were collected at ERIC （Educational Resources Information Centre） database during the first semester of 2016. As analytical categories, we used the ethical procedures established by Brazilian Applied Linguists. The contribution is addressed to both BAL and International Applied Linguists once it offers an overview about a specific topic of research （viz., ethics）. As results, we observed that most of the topics presented by the Brazilian applied linguists were also covered by the research analyses. However, the social relevance was not reported properly by the data and that may be improved.展开更多
