告别月光族 理财软件&工具新年大推荐

俗话说,“你不理财,财不理你“,很多朋友可能都清楚自己的收入,但却不知道自己的消费和支出,所以每个月下来都是“月光族“。这就是由于头脑中没有“理财“的概念引起的,在新的一年开始时,我们有必要共同来探讨一下个人理财的问题,广义的理财不但包括财产资金的管理,还包括利用现在的资金“生财“,但是由于投资顶目有风险,各行各业差别也很大,因此在市专题中,我们主要探讨狭义的理财,那就是对资金的管理,让账目更明确,让消费更理性,日常生活中不但要开源,更要节流,用心理财,你才能做到“心中有账,手里有财“,从此告别“月光族“!     

魔兽·社会·人

一个警察玩魔兽,后来殉职,有玩家在游戏里为他组织了葬礼,很多战友前来祭拜。重庆一个魔兽公会的会长在网上卖号,打算凑两三千块钱给妻子治病,结果无数玩家慷慨解囊。还有一些让人哭笑不得的妙人。比如三季稻,人称三哥,他是国服里的一个传奇人物,独来独往,专杀小号。他不参加任何公会,也不参加任何活动,没有人知道他的真实身份。有个联盟玩家给自己的ID起名叫部落不是东西,然后到处躲避部落的追杀,历尽艰辛,乐此不疲。还有一玩家一根筋要当大奸商,不练级,不打怪,只是在不同种族之间倒买倒卖,囤货居奇,最终控制整个服务器的经济命脉。其实,游戏和现实世界一样.不管是谁,总有点追求。在《魔兽世界》里,有人求升级,有人求装备,有人享受打到BOSS的过程,有人追求领导公会的快感,但也有BJ这样的游侠——他最大的乐趣是发掘游戏里面各种稀奇古怪的地方。他会一个人去爬山、游泳、客串做奸商,躲在没人的地方钓鱼,或者和小妹妹在山顶看日出。为了抓一只宠物,他可以在树下连续盯上40多个小时,如痴如醉,跟谈恋爱一样。走出游戏,又觉得自己很傻。BJ今年33岁,是一个程序员,家住南京,有家庭,有事业,热爱生活。     

评刊

《数码摄影》创刊于新世纪,是本年青的杂志,有年青的感觉,年青的朝气,也有年青的躁动。杂志是智者,面对是朋友,所以我喜欢看各种杂志的卷首语,如沐春风,如听秋雨,有所闻,有所感,很难得,张韬也好,登登也好,如能再精深一些,配图收录会是很不错的图文集。     

站在更高起点

品牌、广告、LOGO;视觉、形象、感性。当读图时代不可避免地到来,企业的形象识别,已跳离了标志的属性,无不关乎企业品质,俨然成为企业的精神图腾和价值地图。在消费时代,并不缺乏视觉饕餮,但是,我们觉得,珍馐美馔,更适合用细嚼慢咽的方式,来咂摸滋味,吸取营养。以后每周,我们将奉上一道精心烹饪的视觉大菜,色、香、味、营养,一应俱全。当然我们也希望您,把让自己齿颊留芳的菜品,写一纸小文,推荐给我们,与更多的读者分享。

2014 这四宗事你准备好了吗?

正2013年蹒跚走远,2014全新驾到,在这除旧迎新的时节里,有太的多事需要我们去做,比如购物,比如给亲友祝福,比如自己的吃喝玩乐,面对它们,我们真的准备好了么?1购物篇,疯狂更要少花钱忙了一年了,谁说不应该趁这个辞旧迎新的日子败败家?不过,购物虽好,精打细算仍很重要,如果花十元钱能买下的东西,你非花一百元买下,那就不是土豪般的潇洒,而是脑袋被驴踢了似的悲哀了。所以买东西时必须要货比三家,此外,有些网店为了能够吸引更多的人气,同时也

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.
