摘要：Most modern tall buildings using lighter construction materials are more flexible, which can lead to excessive wind-induced vibrations resulting in occupant discomfort and structural unsafety. It is necessary to predict and mitigate such wind-induced vibration at the preliminary design stage. Fluctuating across and along-wind loads acting on a tall building that could not be formulated theoretically were simulated numerically in the time domain using known across and along-wind load spectra. These simulated wind loads were used to estimate the across and along-wind responses of a tall building, which are less narrow-banded processes, based on the state space variable approach. The simulated across-wind response of root-mean-square value(0.0047) and that of KAREEM's(0.0040) and the simulated along-wind response of root-mean-square value(0.021) and that of SOLARI's(0.027) were compared. It is found that these are good approximations of closed form responses. Therefore, these numerically simulated across and along-wind loads can be used for across and along-wind responses estimation for the wind-resistant design of a tall building at the preliminary design stage.

摘要：随着汽车向智能化和互联化发展,汽车电磁兼容性(EMC)变得越来越重要。相较于传统的在最后阶段解决电磁兼容问题,将EMC设计和风险控制纳入早期设计阶段至关重要,可以有效实现这一目标的仿真技术也变得愈发关键。通过仿真还可以研究许多电磁兼容问题,如模块级和系统级的电磁干扰(EMI)测试的不一致问题。但由于计算资源、计算机算法的限制以及关键信息的缺乏,汽车电磁兼容的仿真往往具有很大的挑战性。本文以电机驱动系统对安装在混合动力电动汽车(HEV)上的射频天线的射频干扰为例,说明了混合动力车辆级仿真面临的挑战,提出了一种分而治之的解决方案,并验证了其有效性。

摘要：本文以中国美术学院创新设计学院幻觉系列主题课程《每日幻觉剧场》为例,展开讨论本科一年级设计教学实践如何引导学生由物及我地理解数字媒介在当下生活中所扮演的角色,辩证地认识何为真实,并以影像、编程等数字媒体为方法理解和建构自我与世界的关系。课程分为两个阶段,第一阶段的理论部分:感官幻觉和超真实,我们由"何为真实"这一发问展开—如果我们的感官经验不再局限于生物人本身,我们对真实世界的体验将会怎样?在这里,我们利用生物启发性思维,从"化我于物"为视角出发,展开了庄周梦蝶式的哲学思辨和视觉感官实验。在此基础上的第二阶段:从化蝶到拟像的自我,课程纵深聚焦到数字媒体视角下关于真实与拟像的讨论和实验当中,引导学生通过影像、代码等数字媒介展开关于自我以及身份的探索。在以《虚拟之眼》为代表的项目中,同学们通过重构一种叙事情境、重建一种日常现场,建构出一个混合着感官与想象、公共与私密、推理与即兴、幻象与真实的流动舞台。

摘要：The long-term adjustment processes of atmosphere and ocean in response to gradually increased atmospheric CO2 concentration have been analyzed in 70 and 140 a integrations with NCAR fully-coupled climate system model (CSM). In these experiments the CO2 concentration has been increased to double and quadruples the initial concentration, respectively. After 70 a, at the time of CO2 doubling, the model predicts surface air temperature rises by 1.2 and 1.5 K for the globe and the northwestern Pacific Ocean, respectively. The behavior of the quadrupling run is similar: each global and regional mean surface air temperatures increase by 2.8 and 3.0 K at the time of CO2 quadrupling. From the experiments, surface air temperature changes in the northwestern Pacific Ocean will be more distinctive compared with the global average, mainly due to exceptionally large wanning and sea level change near the entrance of the Kuroshio extension.
