基于电子邮件方式传输数据的软件模块设计

研究并设计了电子邮件MUA（Mail User Agent，邮件用户代理）软件模块，给出了实现电子邮件数据流处理及通讯协议实现的具体细节。该模块严格遵循RFC文档，融合服务器认证过程，可以接入Internet上规范的邮件服务器；提供丰富的程序接口，可作为应用系统中的一个通讯模块使用。     

邮件发送客户端SMTP协议的实现

Internet的电子邮件服务系统采用SMTP、POP、IMAP等应用协议。文章以SMTP协议为研究对象,在Visual C 6.0编程环境下应用SMTP协议,通过套接字发送SMTP命令,接收并处理邮件服务器的反馈信息,从而在客户端实现对电子邮件的发送。文章详细讨论了SMTP协议的命令、应答、会话流程、邮件格式化的实现以及在发送SMTP和接收SMTP之间的会话及应答过程。软件采用面向对象,消息驱动及多线程等新技术实现系统中的功能。

The IMAP Connection

IMAP全称是Internet Message Accers Protocol,意为Internet信息存取协议。它是一种访问电子邮件或访问邮件服务器上公告板信息的方法,也就是说它允许客户机邮件程序象访问本地信息一样,访问远程信息。华盛顿大学的站点上提供了多种IMAP的相关信息,访问者可以在该站点上找到有关     

使用IMAP协议收发邮件

IMAP,英文全称Intemet Message Access Protocol（互联网邮件访问协议）,和PoP协议一样,它也是一种邮件获取协议,我们可通过这种协议从邮件服务器上获取邮件的信息、下载邮件等。但与PoP不同的是,IMAP是“双向”的,换句话说,你在电子邮件客户端或移动设备进行的操作,都可自动同步到服务器上,并可通过客户端直接对服务器上的邮件进行操作。同时,IMAP可以只下载邮件的主题,只有当你真正需要时,才会下载邮件的所有内容。     

使用SMTP实现邮件发送设计

电子邮件是在Internet上应用最广泛的通信的方式,它可以有效地进行电子化的数据异地交换。电子邮件工作原理遵循客户/服务器模式和一些基本协议和标准,如SMTP、POP3和MIME等。文章借用套接字以VC为开发工具实现电子邮件的核心报文传输系统。     

基于POP3/IMAP协议的垃圾邮件清理的解决方案

针对当时无法清理公网邮箱中大量的垃圾邮件提出一种解决方案,通过对常见的POP3/IMAP协议原理功能分析,以大家日常工作中常用新浪、QQ邮箱为例,利用客户端软件Foxmail7分别实现在POP3/IMAP4协议下接收电子邮件服务器端到本地客户端,进而实现客户端处理电子邮件,与新浪或QQ服务器端同步更新的方式,最终达到清量公网邮箱的垃圾邮件的目的。     

用Mad Dash精炼Notes

Lotus将在佛罗里达州奥兰多Latusphere用户会议上针对Domino展示一种新的称作MadDash的全功能Internet客户机版本和一个Domino服务器升级版本、这个升级片比旧版本精炼。据报道,这两个版本计划在今年中发行,它们部支持Internet报文传送访问协议4(IMAP4)和小型目录访问协议服务(LDAP)。据知情者透露Mad Dach将支持邮局协议3(POP％)电子邮件并包括一个可由用户定制的接口,据此用户能选择各种     

基于SMTP、POP3协议的电子邮件自动收发系统的开发

电子邮件是Internet上应用最多和最广的服务项目,SMTP(Simple Mail Transport protocol)和POP3(Post office protocol)是在电子邮件服务中分别负责收信和发信的两种协议。本文介绍了电子邮件系统的工作原理及相关协议,并基于这些协议设计和开发了一个实用的邮件系统。     

疑难解答

1.什么是“IMAP”??我在设置Netscape的一些参数时,发现有一项是“IMAP”,什么是“IMAP”?该如何设置?它和“POP3”有什么区别?IMAP是Internet Message AccessProtocol的缩写,中文名是网际消息访问协议。正如POP3是POP协议的第3个版本一样,IMAP4是TMAP协议的第4个版本,它提供了同POP3一样方便的邮件下载服务,而且在邮箱访问上有更加强大的功能。     

Only connect: teaching, technology and telesis

Abstract This paper describes an approach to the design of interactive multimedia materials being developed in a European Community project. The developmental process is seen as a dialogue between technologists and teachers. This dialogue is often problematic because of the differences in training, experience and culture between them. Conditions needed for fruitful dialogue are described and the generic model for learning design used in the project is explained.     

European Community policy and the market

Abstract This paper starts with some reflections on the policy considerations and priorities which are shaping European Commission (EC) research programmes. Then it attempts to position the current projects which seek to capitalise on information and communications technologies for learning in relation to these priorities and the apparent realities of the marketplace. It concludes that while there are grounds to be optimistic about the contribution EC programmes can make to the efficiency and standard of education and training, they are still too technology driven.     

一种自适应子融合集成多分类器方法

融合集成方法已经广泛应用在模式识别领域,然而一些基分类器实时性能稳定性较差,导致多分类器融合性能差,针对上述问题本文提出了一种新的基于多分类器的子融合集成分类器系统。该方法考虑在度量层融合层次之上通过对各类基多分类器进行动态选择,票数最多的类别作为融合系统中对特征向量识别的类别,构成一种新的自适应子融合集成分类器方法。实验表明,该方法比传统的分类器以及分类融合方法识别准确率明显更高,具有更好的鲁棒性。     

Avoiding semantic and temporal gaps in developing software intensive systems

Development of software intensive systems (systems) in practice involves a series of self-contained phases for the lifecycle of a system. Semantic and temporal gaps, which occur among phases and among developer disciplines within and across phases, hinder the ongoing development of a system because of the interdependencies among phases and among disciplines. Such gaps are magnified among systems that are developed at different times by different development teams, which may limit reuse of artifacts of systems development and interoperability among the systems. This article discusses such gaps and a systems development process for avoiding them.     

Designing economic np control charts: A programmed simulation approach

This paper presents control charts models and the necessary simulation software for the location of economic values of the control parameters. The simulation program is written in FORTRAN, requires only 10K of main storage, and can run on most mini and micro computers. Two models are presented - one describes the process when it is operating at full capacity and the other when the process is operating under capacity. The models allow the product quality to deteriorate to a further level before an existing out-of-control state is detected, and they can also be used in situations where no prior knowledge exists of the out-of-control causes and the resulting proportion defectives.     

The development of robot art

Going through a few examples of robot artists who are recognized worldwide, we try to analyze the deepest meaning of what is called “robot art” and the related art field definition. We also try to highlight its well-marked borders, such as kinetic sculptures, kinetic art, cyber art, and cyberpunk. A brief excursion into the importance of the context, the message, and its semiotics is also provided, case by case, together with a few hints on the history of this discipline in the light of an artistic perspective. Therefore, the aim of this article is to try to summarize the main characteristics that might classify robot art as a unique and innovative discipline, and to track down some of the principles by which a robotic artifact can or cannot be considered an art piece in terms of social, cultural, and strictly artistic interest. This work was presented in part at the 13th International Symposium on Artificial Life and Robotics, Oita, Japan, January 31–February 2, 2008     

Explanation and prediction: an architecture for default and abductive reasoning

Although there are many arguments that logic is an appropriate tool for artificial intelligence, there has been a perceived problem with the monotonicity of classical logic. This paper elaborates on the idea that reasoning should be viewed as theory formation where logic tells us the consequences of our assumptions. The two activities of predicting what is expected to be true and explaining observations are considered in a simple theory formation framework. Properties of each activity are discussed, along with a number of proposals as to what should be predicted or accepted as reasonable explanations. An architecture is proposed to combine explanation and prediction into one coherent framework. Algorithms used to implement the system as well as examples from a running implementation are given.     

Three Process Perspectives: Organizations, Teams, and People

This paper provides the author's personal views and perspectives on software process improvement. Starting with his first work on technology assessment in IBM over 20 years ago, Watts Humphrey describes the process improvement work he has been directly involved in. This includes the development of the early process assessment methods, the original design of the CMM, and the introduction of the Personal Software Process (PSP)^SM and Team Software Process (TSP){^SM}. In addition to describing the original motivation for this work, the author also reviews many of the problems he and his associates encountered and why they solved them the way they did. He also comments on the outstanding issues and likely directions for future work. Finally, this work has built on the experiences and contributions of many people. Mr. Humphrey only describes work that he was personally involved in and he names many of the key contributors. However, so many people have been involved in this work that a full list of the important participants would be impractical.     

基于复小波噪声方差显著修正的SAR图像去噪

提出了一种基于复小波域统计建模与噪声方差估计显著性修正相结合的合成孔径雷达(Synthetic Aperture Radar,SAR)图像斑点噪声滤波方法。该方法首先通过对数变换将乘性噪声模型转化为加性噪声模型,然后对变换后的图像进行双树复小波变换(Dualtree Complex Wavelet Transform,DCWT),并对复数小波系数的统计分布进行建模。在此先验分布的基础上,通过运用贝叶斯估计方法从含噪系数中恢复原始系数,达到滤除噪声的目的。实验结果表明该方法在去除噪声的同时保留了图像的细节信息,取得了很好的降噪效果。     

基于QTE的蒙古文显示机制研究与实现

蒙古语言是中国蒙古族使用的通用语言,由于蒙古文区别于其他文字的书写方式和其自身变形机制等特点,在很多通用的文字处理引擎中都不被支持。在嵌入式产品开发与应用领域中Linux加QTE已经成为流行方式。该文给出了一种在QTE环境上实现基于标准Unicode的蒙古文点阵显示和变形算法, 并自定义了支持蒙古文的QTE组件,扩展了QTE功能,为在Linux加QTE方式的嵌入式体系结构中处理蒙古文提供了一种解决方法。
