Internet网络低层编程及Java实现

探讨如何通过因特网通信，以及Java用以辅助此类编程的一些类。网络程序的设计要求相互间更有效率地沟通。Web网页的广泛使用，编程效率提升后影响最大的就是Web。网络程序设计以前非常困难，而Java使这个问题迎刃而解。它解决了一些真正有些难度的复杂问题：跨平台程序、动态代码改换以及安全保护等等。     

利用互联网技术实现机械工程图纸的管理

这里论述使用该系统测量齿轮，不但可以测量齿轮一周内的齿轮径向综合误差（△F^ni），也可以测出齿轮的一齿径向综合误差（△F^ni），充分发挥了齿轮双啮测量应有的优势。该系统即可用于测量齿轮的径向误差，也可以依误差曲线的图形对切齿工艺进行分析。     

移动自组网网关的能源感知

为了提高移动自组网节点能源有效性,延长系统寿命.用增加网关选择的能耗参数,来改进网关优选算法,并对能源节约进行定性和定量分析.试验结果表明,利用改进的网关优选算法可以使网络寿命延长1.42倍,同时对比了两种算法对网络性能的影响,仿真实验结果表明,增加网关选择能耗参数,对网络性能影响很小,系统寿命延长明显.

基于mSCTP的跨层快速切换方案

针对FMIPv6建立隧道和绑定更新过程引起的开销和切换延迟,提出一种利用移动流控制传输协议实现的跨层快速切换方案mSCFHS.该方案使用二层触发机制配置新转交地址,并通过动态地址重配置功能向通信对端注册,消除地址认证过程,同时提前进行家乡注册.仿真结果表明,mSCFHS在切换延迟和丢包率方面都低于FMIPv6,具有较好的性能.     

Wisdom City Management System Based on Internet-of-Things Technology

The city management model of China was extensive administrative management model from the beginning. From the end of the 20th century to the first decade of 21st century, China began the systematic construction and through software system, realizes digital and automatic city management system construction. At present, with the perfection and wide applying of internet-of-things technology, it is possible to build the wisdom city management system based on internet-of-things technology. Wisdom city management system is the upgrading city management system of the digital city and the automatic city. This paper, from the basic concept and basic application of internet-of-things technology, discusses the overall structure, application and value, significance and risk of the wisdom city management system. From the perspective of the work mechanism of city management enforcement department, and based on the internet-of-things technology, this paper probes into the wisdom city management system with the “cover to the surface, monitoring to the line, and control to the point” information acquisition, scheduling and decision-making. It also expounds the function and content in detail from the percep-tion layer, the transport layer, support layer and application layer of the wisdom city management system. It pro-vides the actual maneuverability reference of the construction of wisdom city management system based on the internet-of-things technology.

Psychological Research Online: Report of Board of Scientific Affairs' Advisory Group on the Conduct of Research on the Internet.

As the Internet has changed communication, commerce, and the distribution of information, so too it is changing psychological research. Psychologists can observe new or rare phenomena online and can do research on traditional psychological topics more efficiently, enabling them to expand the scale and scope of their research. Yet these opportunities entail risk both to research quality and to human subjects. Internet research is inherently no more risky than traditional observational, survey, or experimental methods. Yet the risks and safeguards against them will differ from those characterizing traditional research and will themselves change over time. This article describes some benefits and challenges of conducting psychological research via the Internet and offers recommendations to both researchers and institutional review boards for dealing with them.
