“甜似蜜”蜂房小技巧（之硬件精锐篇）

ADSL软件优化很多人在使用普通Modem的时候,都不会忘记对网络进行优化。Modem需要优化,ADSL同样也需要优化。因为Windows在安装时,默认的是网络参数针对以太网的设置。在TCP/IP数据包传送过程中,会浪费一定的带宽,所以还是有优化的余地。用户可以用较常用的软件,如“ADSL超频奇兵”进行优化,以此来最大限度的提高ADSL工作效率。别让Modem充当声卡Modem与声卡不兼容现象是比较常见的,除了可以把Modem更换PCI插槽来解决该问题外,还可以更改两个硬件的默认中断。另外,我们也可以进入系统仔细查看声卡的音频属性,很可能是由于默认设…     

了解ADSL Modem的情况

ADSL用户端使用专用的ADSL Modem。和普通的Modem一样,ADSL的Modem也分为内置、外置,外置又包括以太网接口和USB接口。外置ADSL Modem一般都带有一个独立的滤波分离器,用于把电话线里面的ADSL网 络信号和普通电话语音信号分离,内置ADSL Modem一般都把分离器集成在了内置ADSL Modem卡上,内置ADSL     

Linux下的网络接入及应用

如何在Linux下完成网络设置,如何在Linux下接入互联网、浏览网页、收发Mail、文 件传输? Linux 深受部分计算机用户喜爱的主要原因之一,是它具备非常完整的网络功能。Web 浏览、Mail、FTP、DNS、DHCP、Telnet、SSH、Proxy等等,架构一个网站所需要的这些服务你都可以学习建立。同时对于使用　ADSL、Cable　Modem 和局域网接入等上网方式的用户也都可在它上面实现与Internet互联。局域网接入的网络设置TCP/IP(Transmission　ControlProtocol/Internet　Protocol)是Internet 最基本的协议,简单地说,就是由底…     

3om阐述未来高速访问 趋势ADSL商用 Cable家用

说是未来的高速访问趋势,其实在美国以及欧洲,ADSL和Cable Modem已经走进普通人的工作和生活,即便是国内,已经有部分区域开始了试运行。其实,ADSL和Cable Modem即将于未来的2-3年内走入我们的生活中。这两种技术都可提供较高的网络访问速率,但它们有什么区別呢?ADSL是一种点到点     

“慧眼”近观ADSL Modem

随着宽带的普通，很多用户都开始使用ADSL Modem，但是很多人却并不了解ADSL Modem。在本文中我们就向大家介绍一下ADSL Modem到底有那些小“秘密”。     

网络类

很多ADSL宽带运行商赠送的Modem．都在内部集成了自动拨号功能．如果开启了该功能．那么包括DNS域名解析及IP分配和部分网络防火墙功能．都会交由Modem负担。这样随着网络连接的时间延长．一些低端Modem会因网络数据交换量太大．而产生网络堵塞的情况．造成网络频繁断线或延迟增大的问题,对此除做好散热处理外,在环境温度较高时最好改用ADSL拨号模式．以确保网络连接的稳定。     

为什么我的计算机不能上网——谨防Ethernet ADSL MODEM内置IP冲突

看了“电脑爱好者”2002年24期的“楼上楼下,共享宽带”一文,笔者想提醒大家,在我们配制Ethernet ADSL Modem的时候,Modem内置IP地址与网络计算机的IP地址冲突成为了局域网共享潜在的隐患。下面,笔者将以一个实例来分析这一类的问题。 网络基本情况:宿舍内部局域网,电脑若干台,通过HUB与ADSL Modem相连,ADSL Modem配合一台代理服务器作为整个局域网计算机出口到Internet     

选择ADSL Modem看什么

ADSL对于网民来说已不再陌生了,今年可以说是ADSL年。那么对于使惯了56K小猫的发烧友来说,512K的“大猫”安装调试相对来说要更为复杂,不会象以前56K Modem那样,自己就可以轻松搞定。它要求许多网络的概念。因此ADSL Modem的选购和普通Modem的选购就有些不同,有关专家建议你要从以下几方面去考虑购买适合自己的ADSL Modem: 要看选择的是哪一种接口现在的接口方式有以太网、USB和PCI三种。USB、PCI适用于家庭用户,性价比好,小巧、方便、实用;外置以太网口的只适用于企业和办公室的局域网,它可以带多台机器进行上网。有的以太网接口的ADSL Modem同时具有桥接和路由的功能,这样就可以省掉一个路由器,外置以太网口带路由功能的ADSL支持DHCP、NAT、RIP等路由功能,还有自己的IP POOL     

图解Modem拨号上网常见问题

二、框图详解 是不是拨号Modem 这些性能诊断适用于普通拨号Modem，不适用于线缆Modem、ISDN Modem或任何DSL和ADSL宽带Modem．如果你用的是外置宽带Modem．请按网络故障诊断处理．     

ADSL Modem的四条安全建议

随着ADSL Model路由功能的开启，网络安全问题也随之而来。由于Modem开启路由功能时，使用的是公网IP，而Modem的一些端口(如80、21．23等)是对外开放的。攻击者扫描．探测到之后，通过这些端口攻击Modem，将Modem资源耗尽，导致Modem工作不正常，经常掉线。就像前面介绍的打开ADSL Medom路由功能的方法一样，ADSL Modem的Web管理界面是可以通过IE随便登录的，任何人都可以通过IE连接到ADSL Modem上来。如果默认用户名和     

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。
