Cu—Al—Ni—Mn形状记忆合金高温残留浮突研究

利用金相观察与同步测量电阻的方法,发现 Cu—Al—Ni—Mn 合金直接淬火到 TAf 时,合金表面出现高温残留浮突,X 射线衍射分析证实这种浮突是变形母相。讨论了热循环对这种高温残留浮突的影响。     

基于长短期记忆网络的轨道交通短期OD客流量预测

为了更准确地掌握轨道交通客流在线网中的时空分布,更高效地匹配客流需求与运输能力,实现提高轨道交通运输效率、改善运营服务质量的目的,提出了一种基于长短期记忆网络的短期OD(交通起止点)客流量预测方法。以历史客流数据为基础,定性分析车站间OD客流量的时空相关性,利用回归分析法定量分析客流影响因素,筛选出运营时刻、运营日特征、最低气温3个时间特征。为提高预测精度,以长短期记忆网络为基础,结合时间特征,为每对起讫点单独构建预测模型,形成了基于长短期记忆网络的轨道交通短期OD客流量预测模型。以苏州市为例进行验证,结果表明,加入了时间特征的短期OD客流量预测模型较移动平均模型、仅利用历史客流数据训练的基于LSTM网络的短期OD客流量预测模型,预测结果与真实值之间的误差降低了6.27%～8.58%,所提出的方法和模型可为轨道交通运营部门制定列车运行计划、组织客运工作提供更准确的数据资料。     

How tourism memory boosts creativity? The role of openness to experience

Although tourism memory is widely regarded as a valuable commodity, scant research examines its influence on creativity, a crucial factor for individual and organizational success. Moreover, while both travel and work are vital for human functioning, there are inconsistent views on whether they are opposing domains. This research aims to fill these gaps by investigating the unique characteristics of tourism memories and their effect on creativity at the individual level. Across four studies, we demonstrate that merely recalling one's tourism memory - even from a long time ago - increases creativity. We have also found that this effect is mediated by an increased state of openness to experience triggered by tourism memory retrieval, and one's trait openness moderates this effect. Our research contributes to the literature on tourism, management, and psychology, also offering insights for marketers and organizations to leverage the potential of tourism memories to foster creativity and success.
