In this paper, a wideband 60GHz patch antenna with uniplanar Compact Photonic Band Gap (UC-PBG) and Artificial Magnetic Conductor (AMC) building on 0.13um CMOS technique was proposed. The silicon substrate of CMOS technology affects the antenna efficiency a lot. The meta-material structure in this paper has partly eliminated the loss. According to the unlicensed frequency band announced for commercial...
This paper presents the design and implementation of deterministic linear network coding algorithm according to the structural features of HM-ALM, which is a high-quality application layer multicast system. Through experiments the algorithm characteristics and its impact on multicast performance are analyzed. The experimental results show that the cost of network coding algorithm is related to the...
With the development of e-learning, many authoring tools have been designed and implemented, besides of course authoring tools like eXe, presentation tools like PowerPoint are widely used and play important role in creating learning content. However, most presentation tools do not support PowerPoint files which are very popular in the education because of its complexity. This will lead to poor share...
The three-screen streaming VOD system with three windows of instructor, navigator and PowerPoint is very popular in distant learning which needs high bandwidth. The paper proposes a new idea to reduce the bandwidth to improve userpsilas playing experience by mainly using Web pages transformed from PowerPoint in streaming VOD system instead of the ideas of transmitting screen pictures or screen captivating...
