业务能力开放中媒体资源控制功能的实现

基于业务能力开放网关的业务开发模式越来越受到运营商及增值业务提供商的重视,在向用户提供包含了复杂媒体处理的业务时,能力开放网关还需要进一步完成媒体资源控制功能。分析了目前业务能力开放中媒体资源控制功能实现的研究成果,并以ParlayX网关在会话初始协议（SIP,Session Initial Protoclo）网络中的应用为例,介绍了SIP网络中基于业务开放网关的业务开发及其中媒体资源控制功能的实现。     

Promoting or prohibiting: Understanding the influence of social media on international students’ acculturation process,coping strategies,and psychological consequences

Although the unprecedented prevalence of social media has infiltrated into international students’ daily trajectories and become an indispensable component of their intercultural communication, yet surprisingly few attempts have been implemented to systematically unpack how the innovative technology could play a role in these sojourners’ acculturation experiences and the consequences of migration and cross-cultural adaption. In order to address such research gap, the objective of this present article is to provide a review of academic, peer-reviewed journal studies that examined the potential effect of social media engagement on international university students’ acculturation process, coping strategies, and psychological adjustments during the period from 2010 to 2019. Moreover, building upon conceptualizations from new media and transcultural research literature, a conceptual framework was developed to classify the relevant studies for further analysis. Overall, these theories and studies synthesized in this paper emphasize the vital role of social media in the acculturation, coping behaviors and mental health for ethnic minorities in the host country. Additionally, certain dimensions of attitudes and behaviors through social media could exert the important influence on the psychological adaption. Therefore, conclusions of the research may assist to further inform practitioners who may encounter newcomers’ experiencing intercultural adjustments and psychological issues in the digital media age. Furthermore, this current review may also help educators determine certain barriers that have not been resolved in campus tactics which may influence the acculturation of sojourning populations.

单轴晶体材料的Casimir效应调控研究

Casimir效应最初表现为理想导体平板之间存在的真空作用力,近年来在微机械和纳米机械领域中具有重要影响和作用。考虑单轴晶体平行材料板的光轴几种不同取向,通过电磁场应力张量方法计算了单轴晶体平板间的Casimir作用力,其中平板间为真空区域。仿真结果表明,Casimir作用力在短距下受到较强抑制,而随着板间距的增大抑制逐渐放缓,直至可以恢复到约为理想导体板间力的1/10,同时Casimir力也随各晶体参数发生变化,进而可由此调控Casimir效应。     

基于ARM处理器的流媒体播放器客户端的构建

设计了一种新型的嵌入式流媒体的客户端。它以ARM处理器和Linux嵌入式操作系统为平台,通过对原有Mplayer播放器进行RTP/RTSP功能扩展和移植,开发出了一款在ARM开发板上进行实时流播放的嵌入式流媒体播放器。这种播放器不但继承了Mplayer支持多种媒体格式以及丰富的后期处理滤镜等优点,而且即使在主频仅为200M的三星S3C2410 ARM开发板上也能够进行顺畅的流媒体播放,视频流顺畅,画质清晰,给人的感觉如同视频出自本机一般,非常适合应用于嵌入式系统。

Word-Representation-Based Method for Extracting Organizational Events from Online Media

Online social media exhibit massive organizational event relevant messages, and the well categorized event information can be useful in many real-world applications. In this paper, we propose a research framework to extract high quality event information from massive online media data. The main contributions lie in two aspects: First, we present an event-extraction and event-categorization system for online media data; second, we present a novel approach for both discovering important event categories and classifying extracted events based on word representation and clustering model. Experimental results with real dataset show that the proposed framework is effective to extract high quality event information.
