DELPHI中对注册表的操作

在开发Windows平台等应用程序时，经常要访问和修改注册表，对注册表的操作是进行软件开发的一项重要技能。Delphi是常用的开发工具，那么如何在Delphi中访问和修改注册表呢？下面就来讨论一下。Delphi中提供了几个注册表类，通过对此类对象的操作我们就可以在程序中很方便地访问和修改Windows操作系统的注册表。Delphi中提供的注册表类主要有：TregistryIniFile、TregIniFile、EregistryExcep－tion和Tregistry。前两种主要是为了兼容Win３．x下的ini文件，按照操作ini文件的方式操作注册表；EregistryException用来在程序对注册表…

当涉及注册表

注册表是Windows的神经中枢。我们对系统的一举一动都会反映在其中。系统的很多疑难杂症常常要通过编辑注册表来解决。不过注册表是Windows中相当脆弱的“神经”。一旦有所“闪失”,就会严重损坏系统。甚至让系统瘫痪。那么初学者就只有对它敬而远之了?那初学者如何才能成长?其实只要在修改注册表前作好一些准备工作。就会大大降低修改注册表的危险性。     

半月病毒播报

病毒名称：代理蠕虫变种YD（Worm．Win32．Agent．yd）病毒 病毒类型：蠕虫病毒 影响平台：Windows NT／2000XP／2003 这是一个蠕虫病毒。病毒运行后会把自己复制到系统目录下。并修改注册表启动项实现开机自启动。同时病毒修改注册表信息,来禁用系统任务管理器,禁止Windows自动升级,将系统文件和隐藏文件设置为不可见,以及锁定用户默认浏览器主页。并且试图关闭杀毒软件和安全工具。当病毒发现有标题为“瑞星主动防御”或者“恶意行为检测”的对话框时,就发消息模拟鼠标点击不处理,以此躲避杀毒软件查杀。它还会从网上下载新的木马病毒,并在可移动存储设备写入病毒,以此传播。     

注册表也玩收藏夹

在Windows Vista操作系统中,可以通过修改注册表的方法对系统进行优化处理。不过,对于许多高手来说,告诉新手朋友如何进入某一个具体的注册表位置去进行修改却是既麻烦又危险的事情。因为,新手们对某个并不应该修改的注册位置进行了修改,那么便有可能造成系统不稳定或崩溃的事件发生。如何才能让他们不误入岐途,轻松完成注册表的修改操作呢?其实我们只要妙用注册表的收藏及导入功能,便可以引导他们在安全的环境中完成注册表的修改。     

编程疑难问题解答

使用“系统监视器”协助调节系统性能

Windows小窍门 Windows 98提供了一个“系统监视器”应用程序,它十分类似于Windows NT中“系统监视器”的功能,可以即时地帮助用户监视计算机的系统性能。在运行Windows 98时,系统监视器可以通过采集注册表中的动态数据信息来报告系统进程的变化。因此,如果用户对系统进行了修改或者因为其他硬件的原因而使注册表发生了变化,则系统监视器就可以根据注册表中的情况

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.
