命令行中运行程序随我愿

通常我们在执行程序时。需要先进入该程序所在的目录。然后运行它。显得非常麻烦。为了方便。在桌面上建立一个快捷方式。但带来的结果却是满屏的程序快捷方式。前几天。看见朋友在“运行”对话框中输入Foxmail．exe后即可运行Foxmail。感到挺奇怪的。在我机器上一试。却提示找不到该文件。这是为什么。该问题该如何解决。下面提供两种解决办法。至于为什么。在第二种方法中已说明。     

被咬了一口的苹果——苹果编年史

她是个人电脑的始祖。是那么的卓尔不群。气质不凡。如今似乎被排挤在我们视线的边缘。却仍是我们事实上的潮流引领者。每一款新产品的问世。都可以引起无数人的欢呼。再昂贵的价格也无法阻挡人们对这些艺术品的热爱。但是这是个商业化的社会．尊崇着利益至上的原则。因此她作为一个艺术家．一直遭受着各种各样的磨难。无数未来佳作被迫胎死腹中或是半路夭折。但是他并没有因此倒下。反而变得越来越成熟。今天的她不但更善于创造．同时也更善于生存。世界尚未终结。她的成败功过也无法断定。我们只好藉着过去的回忆。让大家自己来思考……     

感受最真实的音乐 思铂睿音响改装

我会听很多很多的歌,以至于有点乱七八糟。要知道,我的CD多得无法摆上书架。音乐是我的一切。有时侯我会觉得自己是为音乐而生的。音乐就是我的耳朵。这感觉来得如此真实,如此强烈,以至我有些自恋。我就像是一个歌者,台下是已成黑点的观众。而我,从不曾倒下,经常会这样子近乎发呆地想。     

按流量计费——互联网将走向何方？

提到上网收费。大家理所当然地想到当前最为普遍的包月方式。通常我们每个月只要付出60—100元左右的费用，我们就可以无限制地使用网络；也有的用户使用网络比较少。因而使用的是按时间计费的方式。通常可以50元包50个小时。70元包100个小时等。然而。你可曾听说宽带将按流量进行计费。这意味着你在网络上一切导致流量的行为都要收费。包括浏览时事新闻、查阅资料、下载歌曲、软件、电影等。你所浏览的每一个字符，每一bit流量。都需要你买单。     

用增强型51实验板控制液晶显示器

上期我们已经对增强型51实验板中按键、蜂鸣器、继电器的工作原理及使用方法有了一定的了解。也感受到了增强型51实验板的易用、易学和强大的功能。现在我们趁热打铁。再向上跨一步。进一步了解增强型51实验板还能做哪些更酷。更有趣味性的实验。当然。在你决定学习单片机之前。请做好如下准备工作：计算机一台，编程器一只。实验板一块。再准备一只仿真器。如果你想学单片机。这是不可少的不必要配置。好在这些投资并不算多。     

向2009前进

雪灾。汶川地震。股市低迷。金融危机。经济滑坡。这些凑在一起或许就是我们对刚刚过去的2008年的最深记忆。但是,除了悲伤,更应该值得我们记忆的应该是成就。比如奥运会,比如神舟飞船,再比如我们网络安全事业的点滴成绩。     

微软：市场空间愈加广阔

IT厂商们显然认识到了虚拟化市场的巨大价值。并且力图在这个市场中分得一杯羹。为抢占虚拟化市场的份额。2003年微软购买了Connectix公司。EMC收购了VMware。其实。虚拟化不仅仅受到软件行业的关注。也受到了包括AMD和Intel在内的芯片厂商的极大关注。     

保护计算机远离黑客骚扰的策略

在这个网络时代。不安全的因素无处不在。一旦网络或一台计算机被严重地击毁了,系统管理员需要采取行动来对付攻击。在下面的文章中。让我们来看一些常见的选择和假设。并且考虑在处理一个受到攻击的系统时。为什么这些未必是最好的行动。

任务管理器不能直接打开看我的

电脑以前开机都是直接登录系统。不知道什么原因。今天开机时却出现了输入用户名和密码的对话框。而且按〈Ctrl＋Alt＋Del〉也不能直接打开任务管理器。弹出的是“Windows安全”对话框。要单击“任务管理器”后才能打开。十分不方便。怎么办？没关系。我教你解决的方法。     

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。     

How do children do mathematics with LOGO?

Abstract  This paper considers some results of a study designed to investigate the kinds of mathematical activity undertaken by children (aged between 8 and 11) as they learned to program in LOGO. A model of learning modes is proposed, which attempts to describe the ways in which children used and acquired understanding of the programming/mathematical concepts involved. The remainder of the paper is concerned with discussing the validity and limitations of the model, and its implications for further research and curriculum development.
