退却     
“从那段恋情结束以后,你觉得自己变了,身影更加孤独了,烟也抽得更多了,拥有爱情的经历多了以后,你觉得自己废了,再也不动真情了,酒也喝得更多了,当你感觉自己清醒的时候,当你把一切都看明白的时候,你确定你自己已经废了……”  相似文献

倒退个五年左右吧,那时国外有个蛮著名的什么经济学家,提出了一个概念——眼球经济。大致的意思就是说——扯住你的眼球,那些网站之类的就能非常爽。因为他们可以烧钱嘛,有了众多的眼球来看,不对,他们的说法叫浏览——有了众多的眼球来浏览他们的站点,就能有大笔的投资,有了投资,就能让那些CEO们财大气粗地烧钱——反正不是他们的钱,不烧白不烧,烧了才NB。后来,时代进步了,金融风暴来了,网络泡沫破裂了,一批又一批网络公司倒闭了,烧钱的CEO们下台了,网民大叫不好了,中国网络经济完蛋了……谁知有线网络崩溃了,无线联络崛起了,手机短信火…  相似文献

Partial evaluation of Maple   总被引:1,自引:0,他引:1  
Having been convinced of the potential benefits of partial evaluation, we wanted to apply these techniques to code written in Maple, our Computer Algebra System of choice. Maple is a very large language, with a number of non-standard features. When we tried to implement a partial evaluator for it, we ran into a number of difficulties for which we could find no solution in the literature. Undaunted, we persevered and ultimately implemented a working partial evaluator with which we were able to very successfully conduct our experiments, first on small codes, and now on actual routines taken from Maple’s own library. Here, we document the techniques we had to invent or adapt to achieve these results.  相似文献

In this paper we want to explore Field as a concept and as a metaphor for understanding interactive systems. By interactive systems we mean both systems and artworks, where the user by interacting changes the course of events. We intend to show why we need new terms and why we consider Field to be a fruitful concept and term. Further we will show how the Field concept changes both our understanding of what we do as designers and composers and how we acknowledge our audience. We will exemplify the design consequences of the Field concept by going through some design considerations we made when designing the audio tactile installation Mufi.  相似文献

In this paper, we discuss a number of current and future research directions in network optimization. First, we categorize current research efforts as primarily methodological or primarily applied and we carefully define the boundaries of each class. In addition, we survey the present capabilities of network algorithms. Next, we delineate objectives in each class. Finally, we list several network problems for each class that should, in our opinion, be investigated and we give pertinent background information.  相似文献

In this article we describe a new approach to enhance presence technologies. First, we discuss the strong relationship between cognitive processes and emotions and how human physiology is uniquely affected when experiencing each emotion. Secondly, we introduce our prototype multimodal affective user interface. In the remainder of the paper we describe the emotion elicitation experiment we designed and conducted and the algorithms we implemented to analyse the physiological signals associated with emotions. These algorithms can then be used to recognise the affective states of users from physiological data collected via non-invasive technologies. The affective intelligent user interfaces we plan to create will adapt to user affect dynamically in the current context, thus providing enhanced social presence.  相似文献

In this paper we describe an experience in designing a groupware application distributed over the WWW to solve a conference management problem. The system we design coordinates the activities of several people engaged in reviewing and selecting papers submitted for a scientific conference. We discuss why such an application is interesting and describe how we designed it. The architecture we suggest implements what we call an active Web, because it includes entities which we are able to use and provide services offered through WWW infrastructures. Users, agents, and active documents can interoperate using a set of basic services for communication and synchronization. The active Web infrastructure we describe here is based on coordination technology integrated with Java.  相似文献

It is not practical to test a website exhaustively because of too many pages and user groups. So we begin our work at the log files of the Website server, gathering the users' visits and the server's responses in a period of time. Then we analyze and discuss these information, and based on this, we identify the key pages, predominate pages and users' visiting modes. Thus we can allocate the testing resource appropriately, emphasing on these pages and modes. Finally we may improve the display structure of the site and fulfill the functionality of the site, enhancing users' visiting efficiency as possible as we can.  相似文献
