One of the main consequences of the extended enterprise is the emergence of new forms of relationships between the customer and the supplier in order to ensure the quality of service of the object throughout the life cycle. Innovative communication and co-operation methods are needed to support these new relationships. The combination of modern information processing and communication tools, commonly referred to as tele-service, offers the technical support required to access remote information. Indeed, it is easier to transfer information and knowledge to different actors than to move an actor to the site. However, even if this technical support is necessary for information communication, it is insufficient to develop a co-operation-based working situation that involves many self-motivated customers and suppliers sharing a common goal. This synergy is an emergent property of the system as a whole, and it is not expected to be obtained as a simple sum of its components. For example, a challenging problem in the field of product manufacturing is to assist the operator in its decision-making, when the system functioning is degraded, to preserve the system under service at maximum (anticipation of the failure) while remaining it in a space of allowed operation (to avoid consequences of an error in judgement). That means an evolution from tele-service to e-work and e-maintenance in particular where the assistance to operator results from collaboration of maintenance processes and experts. Consequently, this paper examines some issues and challenges involved in the evolution from the tele-maintenance of an industrial platform to the e-maintenance, and then proposes a multi-agent system-based collaboration as a solution to implement the e-maintenance experiments.  相似文献

遗传规划算法在化合物设计、筛选研究中的应用   总被引:2,自引:0,他引:2  
采用计算机科学中新兴的遗传规划算法思想,结合化学物质的本质特点,运用进化操作来实现化合物的合成设计和筛选。文中针对算法运用讨论了函数集、终止集问题,通过计算元素组成的字符串的化合价的结果来确定适应度函数,既符合化学学科的本质规律,又满足了算法的要求。通过复制、交换和突变操作,经过多代次的进化终止,取得了满意的结果。文章还针对其实用性,从化学本质出发,提出了建议和研究方向。可以说本文是遗传规划在化学化合物合成筛选中运用的成功探索,同时也为进一步研究打下了坚实的基础。  相似文献

This study set out to investigate the type of media individuals are more likely to tell self-serving and other-oriented lies, and whether this varied according to the target of the lie. One hundred and fifty participants rated on a likert-point scale how likely they would tell a lie. Participants were more likely to tell self-serving lies to people not well-known to them. They were more likely to tell self-serving lies in email, followed by phone, and finally face-to-face. Participants were more likely to tell other-oriented lies to individuals they felt close to and this did not vary according to the type media. Participants were more likely to tell harsh truths to people not well-known to them via email.  相似文献

This research compared grasps to real surfaces with grasps to virtual surfaces, and used virtual surfaces to examine the role of cues to surface shape in grasp. The first experiment investigated the kinematics of overhand grasps to real and virtual objects. The results showed that, compared with grasps to real surfaces, grasps to virtual objects were different in the deceleration phase of the grasp movement and were more variable in their endpoint position. The second experiment used several measures to examine the relationship between the visual perception of a surface and the decision to grasp the surface with either an over-or underhand grasp. It was found that visual perception of the surface was consistent with the grasping decision. The third experiment used virtual surfaces to examine how the removal of visual cues to shape affected the decision to switch from over- to underhand grasp. Results showed that the orientation at which the decision switched was dependent on the visual information content. Overall, the results showed that subtle differences existed between the reach to grasp movements towards real and virtual surfaces and that the decision to choose between grasp types was dependent on the visual information used to depict the virtual surface. These results are discussed in relation to the design and use of input devices to enable manipulation of three-dimensional objects in virtual worlds.  相似文献

This paper considers the nature of medical work and how new telemedicine technologies can be developed to support that work. Telemedicine developers attempt to increase communication and collaboration between medical practitioners and between patients and medics, with the goal being to make medical care and information more easily accessible. However, the focus of telemedicine systems appears to have so far been technology centred, and the work they are trying to support is often ignored. We argue that to develop appropriate telemedicine technologies, it is important to understand the nature of medical work, and to examine the manner in which medical practiceactually occurs. Only then will we be in a position to design appropriate telemedicine technologies to support these activities. Unless designers have an insight into the work itself, new technologies will continue to fail to support what telemedicine effectively aims to promote — collaboration and access to distributed knowledge.  相似文献

IPv6协议下域名系统的扩展与实现   总被引:1,自引:0,他引:1  
为了实现对IPv6协议的支持,需要对现有IPv4协议下的域名系统进行相应的扩展,以使其能在IPv6协议下正确地进行IP地址与域名的正向或反向解析。域名系统的扩展主要包括以下两方面:一是增加了两个新的资源记录AAAA和A6来存储IPv6地址,以实现域名到IPv6地址的正向解析;二是增加了两个新域:ip6.int和ip6.arpa,以实现IPv6地址到域名的反向解析。文中以著名的域名系统软件BIND为对象,以Linux操作系统Redhat9作为实验平台,详细介绍了基于Linux平台的域名系统对IPv6协议的扩展与实现,从而为实现IPv4到IPv6的平稳过渡打下了坚实基础。  相似文献

Security warning is a form of computer dialog communication used to inform the users on the risks of allowing random applications to run on a computer system. Accordingly, it is specifically designed to impersonate a legitimate security alerting function (e.g., notify, warn, and advice) to a user about the consequence effect of an action. However, most of the computer users tend to ignore those security warnings conveying the same message over and over again. This eventually leads to habituation. Considering the fact that there is a significant lack of focus paid to address this issue, the main objective of this article is to describe and summarize the related studies on users’ habituation to the security warnings. This article presents a systematic literature review to explore the current key issues, challenges, and the possible solutions related to habituation effects in security warnings. It is expected that this article could contribute to a more complete understanding of the habituation effects in security warnings and eventually bring benefits to the research communities or general publics.  相似文献

随着具有一定计算能力和无线通信能力的智能传感器(称为mote)的出现,越来越多的物联网应用可以实现对环境及其变化的就地感知、就地决策和就地反应.但因为mote的感知能力和感知范围有限,它们需要协同感知才能更全面地感知环境的状态,才能更好地适应环境的变化.而传统的mote协同感知的实现方法要求开发人员过多地关注mote之间的交互逻辑,并且mote应用也无法适应复杂环境的不断变化.为了避免开发人员在交互逻辑上花费过多的精力,同时保障开发出来的mote应用系统能够适应不稳定的外界环境,提出了一种基于元组空间的mote协同感知支撑机制,使得mote之间的协同感知过程(包括交互的建立过程以及对环境变化的适应过程)对开发人员完全透明.最后实现了一个简单的应用场景,展示了该方法如何满足功能需求以及在环境发生变化时如何对环境进行适应.  相似文献
