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

《Information Security Journal: A Global Perspective》2013,22(6):310-319
While acknowledging the many benefits that cloud computing solutions bring to the world, it is important to note that recent research and studies of these technologies have identified a myriad of potential governance, risk, and compliance (GRC) issues. While industry clearly acknowledges their existence and seeks to them as much as possible, timing-wise it is still well before the legal framework has been put in place to adequately protect and adequately respond to these new and differing global challenges. This paper seeks to inform the potential cloud adopter, not only of the perceived great technological benefit, but to also bring to light the potential security, privacy, and related GRC issues which will need to be prioritized, managed, and mitigated before full implementation occurs. 相似文献

Supporting Public Availability and Accessibility with Elvin: Experiences and Reflections 总被引:7,自引:0,他引:7

We provide a retrospective account of how a generic event notification service called Elvin and a suite of simple client applications: CoffeeBiff, Tickertape and Tickerchat, came to be used within our organisation to support awareness and interaction. After overviewing Elvin and its clients, we outline various experiences from data collated across two studies where Elvin and its clients have been used to augment the workaday world to support interaction, to make digital actions visible, to make physical actions available beyond the location of action, and to support content and socially based information filtering. We suggest there are both functional and technical reasons for why Elvin works for enabling awareness and interaction. Functionally, it provides a way to produce, gather and redistribute information from everyday activities (via Elvin) and to give that information a perceptible form (via the various clients) that can be publicly available and accessible as a resource for awareness. The integration of lightweight chat facilities with these information sources enables awareness to easily flow into interaction, starting to re-connect bodies to actions, and starting to approximate the easy flow of interaction that happens when we are co-located. Technically, the conceptual simplicity of the Elvin notification, the wide availability of its APIs, and the generic functionality of its clients, especially Tickertape, have made the use of the service appealing to developers and users for a wide range of uses. 相似文献

When presented with the option to use a new instructional technology, students often face an approach–avoidance conflict. This study explored promotion and prevention orientations, concepts linked to approach and avoidance in Higgins's regulatory focus theory, in the choice to attend lectures or watch them online. Openness, a core disposition in the Big Five Model of personality, and positive attitudes towards the utility of the Internet, reflect promotion orientations that are potentially related to the choice to watch lectures online. By contrast, neuroticism, another core disposition in the Big Five Model, and anxiety about the Internet as a computer technology, reflect a prevention orientation that is potentially related to the choice of attending lectures in class. The results illustrate that both promotion and prevention are at work in the choice to attend lectures or to watch them online. Neuroticism and anxiety about the Internet as a computer technology were related to the choice to attend lectures in class, whereas the perceived utility of the Internet was related to the choice to watch lectures online. Instructional mode choice was not related to examination performance, suggesting that the choice to attend lectures or watch them online has more to do with individual differences in promotion and prevention orientations than with pedagogical characteristics that impact learning. 相似文献

蜜罐技术能及时发现网络入侵、记录入侵过程并能保存入侵记录而在网络安全中越来越受到重视。蜜罐作为一种"诱骗"和"延缓攻击"手段是有效的,但在实施中存在成本过高、攻击过程不易监控、过程日志不易保存等问题。蜜网技术完善了蜜罐技术,部署的安全系统对入侵者来说更具有迷惑性,更易于保存记录、监控与分析入侵过程。利用VMware实现蜜网技术是最为经济并且有效的方法。 相似文献
