Notes服务器

我们用300台客户机PC测试了Notes服务器OS平台。从结果可以看出多个CPU对应用服务器的影响。Windows NT内置的SMP支持使其领先一步。Solaris同去年相比进步最快。 数字的含义 运行在双处理器上的Lotus Notes server for Windows NT的测试结果同Solaris系统十分接近,很显然第二个处理器显著提高了Windows NT的性能。在只有一个处理器时Windows NT遇到麻烦,问题出在我们最常用的IPX协议方面。     

Notes升级

新版Notes和强大的服务器操作系统平台为Notes管理员带来升级新思路。     

Notes如何发展

如果Notes Release 4还不能促使你进行升级,Lotus准备发布两个新的升级版本,使你的Notes环境更具灵活性。这些独立发售的版本许诺要使Web浏览器用户更容易地访问Notes,给终端用户提供日历和规划程序。新增的服务器功能第一次使得Notes管理员可建立起廉价的容错服务器。 Release 4.11包括了已被大肆渲染的、集成的Notes 和Web服务器。Web服务器特性使得普通的Internet和intranet Web浏览器用户也可以进行访问。Release 4.11使得Notes服务器可将Notes数据库转换成HTML页面。由于文档、查看对象和Notes Navigators能实时地进行转换,浏览器用户     

搞定Lotus Notes

1．为什么LotusDmino却我排夺次安装新的服务器对安装不上？因为windows95／98提供的卸载工具不能完全把Notes卸载干净,上一次服务器的一些配置信息并未删除,如果第2次安装的服务器配置与第1次不同,你还需要把Wild。Is目录下的Notes．ini以及Notes＼Data文件夹下的server．id和cert.id文件删除掉方可。2．为什么后劲LotusNotes4．6的个AWeb浏览器访问intranet有对不能成功？因为Notes4.6与4.5不同,前者增强了对Web的支持,几乎不用做任何设置就可以正常上网。如果出现个人Web创览器不能访问web页面,大部分情况是由于用户上次退出…     

工作流结缘Notes

记者李逊高凌报道 3月6日,莲花软件(中国)有限公司与香港集高科技有限公司在京联合发布JetFIo For Notes产品。JetFlo For Notes是集高科技开发的全中文界面的基于Notes的图形化工作流生器,用户可以运用拖拽(Drag&Drop)手段,自己定义工作流程,然后在Lotus Notes平台上把文档按照所定义的规则进行流转,无需编程,使Notes获得大幅度的延伸。据悉,目前市场尚没有全中文界面的同类产品。除日本外,中国是第二个发布此产品的国家。会上还赠送了JetFlo For Notes全功能评估版和GTX光栅矢量混编软件等其他产品的评估版。作为先进的客户机/服务器平台,Lotus Notes在全球已拥有超过2000万的用户。     

网上办公用Notes

全球性的信息化、网络化进程正改变着人们的生活方式,Internet技术的应用给工作、娱乐乃至日常生活的各个层面都带来了深刻的影响。大量的企业、研究机构、政府和个人将越来越多的资源投入到Internet之中,并获得了巨大的成功,同时这些成果又通过共享方式越来越被人们所接受。 在我国,政府部门掌握着80％的社会资源,建立了3000多个大型或超大型数据库。一直以来,各级政府拥有着大量宝贵的信息资源,但这些资源却没能被有效地利     

Notes对Exchange寸土必争

Lotus公司已经失去了曾经同微软公司共享的桌面产品应用市场,又在面临着来自他开辟的另一个领域的Redmondians威胁:通信和组件。根据电子邮件和信息系统的报告,在第2个季度中,Lotus往通信排名上,总销售额落到了微软后面:Microsoft Exchange销售总数为355万;Lotus Notes的310万。这是上一个季度,Notes以305万对270万领先了Exchange之后,首次被Exchange战胜。但Lotus仍然占有巨大的领先地位,Notes营业额为2510万,Exchange为1660万。今年是Notes销售最好的年份,超出了2000万的销售额,一个季度就多出了500万。当Domino 5.0上市后,Lotus在年末将会有更好的收成。但是Lotus仍然很担心。由于用户欣赏Exchange的易于使用,以及同其它的微软     

让Notes大放异彩

Lotus开发公司的统计数据表明,近百万人正通过Lotus Notes分享着组件的快乐。毫无疑问,Lotus建立了深受大家喜爱的新一代应用程序。 但Notes并未与以前决裂,用于开发Notes应用程序的接口基本上还是基于十多年前Lotus 1-2-3所用的宏语言。尽管我们必须承认从那时到现在,宏语言已做了很多扩展,但在让Lotus便于解释你的指令还是让你便于书写这些宏语言两个选择之间,Lotus显然为前者想得更周到。还好,Lotus为你开了一扇后门,使你能与外部程序取得联系。     

Symantec加固Notes防护

日前,Symantec公司在京发布针对LotusNotes/Domino系统的防病毒软件NortonAntiVirus for Lotus Notes简体中文版,为以Lotus Notes/Domino系统为中央联络系统平台的用户提供了一个坚固的病毒防护盾,以确保整个系统安全通畅运作。除防毒功能强大外,该产品的所有操作都在Notes模式下进行,操作界面为Notes界面,因此用户无需学习新的界面操作就可轻易掌握各项功能,从而大大降低了培

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.

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.

Mr. Twinn’s bombes

This article discusses the history and design of the special versions of the bombe key-finding machines used by Britain’s Government Code & Cypher School (GC&CS) during World War II to attack the Enigma traffic of the Abwehr (the German military intelligence service). These special bombes were based on the design of their more numerous counterparts used against the traffic of the German armed services, but differed from them in important ways that highlight the adaptability of the British bombe design, and the power and flexibility of the diagonal board. Also discussed are the changes in the Abwehr indicating system that drove the development of these machines, the ingenious ways in which they were used, and some related developments involving the bombes used by the U.S. Navy’s cryptanalytic unit (OP-20-G).     

Enhancing a leaf radiative transfer model to estimate concentrations and in vivo specific absorption coefficients of total carotenoids and chlorophylls a and b from single-needle reflectance and transmittance

The relative concentrations of different pigments within a leaf have significant physiological and spectral consequences. Photosynthesis, light use efficiency, mass and energy exchange, and stress response are dependent on relationships among an ensemble of pigments. This ensemble also determines the visible characteristics of a leaf, which can be measured remotely and used to quantify leaf biochemistry and structure. But current remote sensing approaches are limited in their ability to resolve individual pigments. This paper focuses on the incorporation of three pigments—chlorophyll a, chlorophyll b, and total carotenoids—into the LIBERTY leaf radiative transfer model to better understand relationships between leaf biochemical, biophysical, and spectral properties.Pinus ponderosa and Pinus jeffreyi needles were collected from three sites in the California Sierra Nevada. Hemispheric single-leaf visible reflectance and transmittance and concentrations of chlorophylls a and b and total carotenoids of fresh needles were measured. These data were input to the enhanced LIBERTY model to estimate optical and biochemical properties of pine needles. The enhanced model successfully estimated reflectance (RMSE = 0.0255, BIAS = 0.00477, RMS%E = 16.7%), had variable success estimating transmittance (RMSE = 0.0442, BIAS = 0.0294, RMS%E = 181%), and generated very good estimates of carotenoid concentrations (RMSE = 2.48 µg/cm², BIAS = 0.143 µg/cm², RMS%E = 20.4%), good estimates of chlorophyll a concentrations (RMSE = 10.7 µg/cm², BIAS = − 0.992 µg/cm², RMS%E = 21.1%), and fair estimates of chlorophyll b concentrations (RMSE = 7.49 µg/cm², BIAS = − 2.12 µg/cm², RMS%E = 43.7%). Overall root mean squared errors of reflectance, transmittance, and pigment concentration estimates were lower for the three-pigment model than for the single-pigment model. The algorithm to estimate three in vivo specific absorption coefficients is robust, although estimated values are distorted by inconsistencies in model biophysics. The capacity to invert the model from single-leaf reflectance and transmittance was added to the model so it could be coupled with vegetation canopy models to estimate canopy biochemistry from remotely sensed data.
