“影像传输型猥亵”具有不同于传统猥亵犯罪的独有特点,引发入罪的“肯定说”与“否定说”之争。然“两说”均以“影像传输型猥亵”共性的不同侧面为着眼点,对司法实践的指导意义有限。基于功能主义与目的理性的现代刑法理念,“影像传输型猥亵”的妥当刑法评价,应以传输影像是否包含受害者的性敏感部位与可识别身份的面部信息为着眼,全面适用《刑法》分则关于猥亵犯罪、淫秽物品犯罪、侮辱罪等罪名,结合各罪的规范保护目的,构建类型化的刑法适用体系。

相对空中同构无人系统,空地异构无人系统的运动能力、资源载荷、作战场景等异构性质会导致约束条件增多,使求解模型计算量显著增加,协同作战任务的建模和大规模问题的高效求解是需要解决的关键问题。以无人系统完成任务的时间、路径代价、侦察收益为目标函数,同时考虑无人平台续航能力等约束条件,合理构建了空地异构无人系统侦察任务的多目标规划模型;针对具有多威胁区的城市作战环境,考虑无人平台任务路径的安全性和时效性,分别提出了无人机和无人车改进A^(*)算法路径规划策略。针对蛇优化算法(snake optimizer,SO)优化效果不稳定、容易陷入局部最优解的问题,结合粒子群算法和遗传算法提出了改进蛇优化算法(improved snake optimizer,IMSO);通过Python语言进行了仿真验证和与现有算法的对比分析,验证了模型的可行性和算法的优越性。不同算法在由小到大的3种任务载荷设置下独求解10次,IMSO的平均目标函数值分别为SO的100.11%、108.99%和110.01%,可以看出IMSO能多次跳出局部最优,算法的稳定性、最终适应度值均好于SO,在较大规模问题的求解上更具有优越性。

青藏高原雨季时长及雨季降水量的长尺度定量重建,是揭示高原西风、季风时空演变规律及其生态环境效应的关键,其中准确判断高原雨季的起止时间是研究难点.本文通过寻找降水拐点的方法确定了高原不同地点的雨季起、止时间,并计算了雨季时长和雨季降水量,建立了表土孢粉组合与雨季起止时间、雨季时长和雨季降水量的转换函数,重建了具有年纹层沉积特征的高原北部库赛湖区和中部江错湖区过去2000年来的雨季起止时间、雨季时长和雨季降水量变化.结果表明,过去2000以来,库赛湖区雨季降水序列记录了5次高降水时段:AD580~680、AD1000~1100、AD1200~1450、AD1550~1780、AD1920至今,其普遍对应雨季天数长的时段;江错湖区雨季降水序列记录了4次高降水时段:AD80~500、AD800~950、AD1250~1450、AD1780至今,其与雨季天数长的时段在AD1000以前对应良好,在AD1000后关系不明确.在空间上,高原雨季降水呈现出“南北同湿”、“南北同旱”、“南湿北旱”和“南旱北湿”四种模式,其中“南北同湿”可能与异常强盛的夏季风有关,“南北同旱”与弱西风和弱季风有关,“南湿北旱”与强季风和弱西风有关,“南旱北湿”与弱季风和强西风有关.本文从雨季降水的角度揭示了高原2000年来雨季起止时间、雨季时长及雨季降水量的时空演变模式,为进一步认识西风、季风耦合作用提供了自然背景的支持.

通道二次流作用下,涡轮叶片吸力面气膜轨迹呈收缩状从叶片两端朝叶中偏转。针对该问题,本文设计了高压涡轮叶片吸力面双排分区域复合角气膜冷却模型,并采用数值模拟的方法,分析了二次流和复合角对气膜冷却特性的影响。结果表明,在近端区,叶片上游孔排SS1形成的气膜受马蹄涡的作用偏转较小,叶片下游孔排SS2形成的气膜受较强通道涡的影响偏转角远大于上游气膜;在叶片吸力面增加朝向端壁的复合角设计,可以改善气膜覆盖的均匀性,复合角增大至30?左右时,可以消除射流的脱壁现象,最大复合角工况相比于简单角工况的展向平均气膜冷却效率提高了13.9%。

量子科技的飞速发展使得大规模量子计算机的实现只是时间问题,一些量子算法的提出(如Shor、Grover、Simon)使得对现代密码体制(公钥密码和对称密码)实施量子计算攻击成为可能,从而严重威胁经典密码的安全。为提升密码系统抵抗量子计算攻击的能力,以格密码为代表的后量子密码(PQC)算法得到广泛关注和研究。从经典密码算法到PQC的迁移是密码系统实现量子安全的有效路径。首先,该文调研了NIST,ETSI及其他组织和学者提出的PQC迁移路线,总结起来,就是以NIST为代表的替换方案、以ETSI为代表的二次加密方案以及其他混合加密方案三种迁移路线;其次,针对PQC迁移过程,从迁移目标、迁移准备、迁移实施三个环节介绍了迁移策略;此外,为了促进PQC迁移的顺利高效实施,提出了需要考虑的迁移评估要素,包括资源投入、时间成本、业务风险、维护成本、用户体验、商业影响六个方面;最后,提出PQC迁移下一步研究方向。总之,文中工作将为PQC迁移的方案设计和高效实施提供有益参考。
