Modern Mechanical Engineering 2011年第2期1卷 31-37页

作者： phuc Hong Pham Dzung Viet Dao School of Mechanical Engineering Hanoi University of Science and Technology (HUST) Research Institute for Nanomachine System technology Ritsumeikan University

this paper summarized and reviewed recent studies of micro transportation systems (MtS) in the MEMS (Micro Electro-Mechanical System) field. Micro transportation systems can be identified and classified into three categories based on the contact types between the objects and the actuators (i.e. liquid-based, solid- based and air-bearing type). their advantages and disadvantages were also analyzed and compared. the au- thors have proposed and developed three types of solid-based MtS utilizing electrostatic comb-drive actua- tors and ratchet mechanisms to drive the micro container in straight and curved paths. these MtSs have been fabricated with silicon-on-insulator (SOI)-MEMS technology and tested successfully. In the near future, MtSs can be applied in different fields such as medicine (to classify and test blood cells), in bioengineering (to capture, sort and combine bio-cells, DNA), or in micro robot systems.

IMS被看作是下一代多媒体通信非常有前景的解决方案. IMS将会在几乎任何地方、任何时间、任何设备上产生互联网技术变革。例如:电子邮件、网络、即时通讯、虚拟现实和视频会议等。并且,用户在任何时刻、任何地点产生的多媒体服务需求,能看多种设备上实现,比如说移动终端。这些需求需要高性能的移动管理机制,因此,MIP和SIP是最适合于集成在IMS架构中的。当前IMS网络表现出来的问题主要是和高速增长的阻塞增长率、定性的流量控制的需求以及有效网络资源的利用。这是满足这些需求所需要的。这些挑战被tE实践证实了。从对tE函数的分析中,得出了网络中可控可数的流量组织。从这个角度说,有一个MPLS的技术成为一种可行的解决方案。最鼓舞人心的利处来自控制和前向平台的分离,这样可以带来增强的可测性和适应性。为了支持高性能的移动管理机制,其中MIP和SIP是最合适的。这篇论文的主要主题和对象是MPLS技术的tE潜力的研究。研究发现了完善tE的手段也就是提供弹性的方式。这些课题会被围绕着MPLS内部操作、信号传输协议、网络弹性相关性的研究在上下文中展现出来。研究结果表明,协议整合在SIP阶段启动时信号传输低消耗时非常有效。这项结论将会对IMS操作者如蜂窝式无线通讯系统的提供者非常有价值。MPLS的tE特性通过OPNEt建模工具,证明了网络模型的实施和仿真。

驾驶员的停车场选择行为受到诸多因素的影响,这些因素将驾驶员的行为和车辆类型区分开来。在许多发展中国家,城市交通以摩托车为主,这种交通工具的多样性造成了许多交通问题,包括车辆所有权,交通拥堵,交通事故或者与之相关的停车问题（如停车位不足,非法停车等）。本研究阐明了停车场选择模型的影响因素,该模型不仅考虑汽车驾驶员,还考虑了摩托车驾驶员。本研究采用随机效用最大化（RUM）假设下的各种离散选择模型,对影响驾驶员停车选择行为模型的因素进行了评估。结果表明,混合logit模型对胡志明市摩托车和汽车驾驶员数据的处理效果较好。停车费用、停车场到目的地步行距离、停车场容量和排队时间对摩托车用户和汽车用户的停车选择均有显著影响。导航和路牌变量对汽车用户的停车选择有显著影响,但对摩托车用户的停车选择影响较小。本研究结果旨在为发展中国家和摩托车为主要交通方式城市的城市交通规划、停车需求预测和管理提供帮助。同时,研究结果有助于提高停车服务质量,减少停车问题对交通的影响,为未来技术解决方案的实施奠定基础。

新冠疫情的爆发,使得在线教学以一种强势的姿态,取代线下课程进入了全球的教学领域,越南也是如此,疫情过后,虽然越南已经恢复了传统的线下课堂教学,但是线上教学在进行的两三年间,对整个教育教学方式的影响依然在持续,它使得更多的人开始关注互联网融入教学,倒逼教学方式进行改革,教学理念进行更新,从而提高教学效率,激发学生学习兴趣。汉语作为一门强势的外语学科,在越南的各个教育阶段都受到极大的重视,语言教学有其独特性,要求课堂多互动、多联系、多应用,在线汉语教学的开展为越南的汉语教学开拓的新的思路和合作路径,借助与互联网突破空间局限的这个特点,越南汉语教学开始呈现出越来越多的跨区域、跨国际的合作教学趋势,本土的汉语课堂通过互联网链接孔院课堂或者中国课堂的同时,可以突破空间的距离,提高学生学习兴趣,达到更好的教学效果,但是通过对疫情期间的线上汉语教学的调查发现,线上教学在达成语言教学的要求的过程中,存在诸多问题。本文拟通过分析和研究疫情期间越南黄文树高中线上汉语教学中存在的问题,并且提出相应的改进策略,以期为后续的通过线上汉语课堂进行跨区域或者跨国际的进行提供一定的借鉴,提高教学效果,促进越南汉语教学和新的教育技术结合,以及汉语教学的可持续发展。黄文树高中在汉语教育的领域获取了很大的成绩,在越南本土汉语教学领域具有一定的代表性,但在疫情时期,同样也面临巨大的挑战,在线汉语教学解决了学生在疫情时期无法进行课堂学习的问题,成为当时状态下的最优选择。但是线上汉语教学在教学方式、教学资源、学生的学习方式、师生互动和学习环境等等方面都存在一定的问题。本人针对黄文树高中汉语班学习汉语在疫情时期进行研究。希望能通过这次研究发现问题在疫情时期学习汉语,并提出意见能改进,帮助教师和学生,提高学生的学习能力。本论文拟通过过调查黄文树高中的学生、教师疫情时期在线汉语学习和教学情况,了解学生在线汉语学习中的行为、态度,教师线上汉语教学中遇到的困难和存在的问题,提出建议和策略,并且探讨疫情期间的线上汉语教学对疫情后的线下课堂中教师的汉语教学和学生的汉语学习产生的影响,希望后续需要进行的越南本土线上汉语教学能够提前解决曾存在的困难,规避问题,做更周全的准备。本文总共分为六章,第一章是绪论,主要内容是研究缘起,选题意义和研究方法与研究综述;第二章是黄文树汉语教学历史和现状与线上汉语教学现状;第三章是学生在线汉语学习现状;第四章是教师在线汉语学习现状;第五章是学生学习汉语对新冠疫情后的展望;第六章是线上汉语教学存在的问题与不足之处,并提出相应的对策和建议,最后是结语部分。
