公私合作治理模式作为一种前瞻性和创新性的治理方式,是国家治理从消极义务向积极义务的螺旋式升级的体现,特别是在智能社会治理中尤为体现其治理优势。文章以智能社会治理中较为突出的个人信息保护领域为重点讨论公私合作共治的法律问题。公私合作治理以行政委托、协商制定行政规则以及公私合作规制的方式促进公权力和私权力的深度合作,符合个人信息保护的效益原则。然而,在明确引入合作治理机制后,有必要厘清可能存在的法律风险,防止造成行政法向私法逃遁、引发私权力的滥用及腐败、隐私政策的效力不清以及对第三方机构的监管不完善等问题。对于公私合作治理模式下的个人信息保护,还应关注私权力集中的平台责任以及国家担保责任的机制嬗变,为公私合作治理模式在个人信息保护上发挥作用扫清障碍。

1 Abaqus显式分析与隐式分析有何不同?Abaqus提供显式和隐式2种求解类型。显式求解适用于处理动态问题,尤其是高速冲击或爆炸问题。在显式求解中,时间步长明确定义,并且每个时间步长都直接计算结果,无须迭代过程。这种方法对于具有明显惯性效应的问题非常有效,例如冲击、爆炸、碰撞等。显式求解的优点是计算速度快,但受稳定性条件的限制,适用于短时间内发生的动态行为。

通过分别掺入水泥和固废基固化剂对粉煤灰-土进行固化试验,研究对比两种固化材料对粉煤灰-土的固化效果的差异.通过无侧限抗压强度试验和水稳定性试验探讨固化剂掺量、种类和龄期对粉煤灰-土性能的影响,综合评价两种固化材料固化粉煤灰-土的综合路用性能,并通过X射线衍射分析固化材料固化粉煤灰-土的微观机制.结果表明:相同龄期条件下的固化粉煤灰-土的无侧限抗压强度与固化材料的掺量呈正相关关系.相同固化材料掺量条件下,固废基固化剂固化粉煤灰-土的7d强度低于水泥固化粉煤灰-土,28d强度赶超水泥固化粉煤灰-土.固化粉煤灰-土的水稳定性系数随固化材料掺量的增加而提升,而随龄期的延长出现降低的规律.固废基固化剂固化粉煤灰-土的水稳定性系数后期要优于水泥固化粉煤灰-土的水稳定性系数.

深度学习网络是一种端到端的黑箱模型,对网络进行可解释分析可以更深入理解网络内部运行机理以便合理优化网络结构和调参。目前基于Transformer网络的轴承故障诊断模型必须借助时频分析等方法对时域信号进行升维,使其转换为时频图等二维图像以便于可解释分析,这种方法存在着升维过程中参数固定、网络参数量过大和网络可解释性较差等缺点。针对以上问题提出融合网络内自适应升维方法、卷积自注意力模块(convolutional self-attention module)以及中间层类激活热力图(mid layer class activation map, ML-CAM)的卷积自注意力自适应升维网络(convolutional self-attention adaptive dimension-increasing network, CSADI-Net)。卷积自注意力模块使用卷积层获取特征图的查询(query, Q)、键(key, K)和值(value, V),极大地减少了可训练参数量;网络内自适应升维方法通过内部特征图拼接等操作将升维过程与网络训练融合,使其具有自适应参数调节的能力;中间层类激活热力图可以将网络内升维方法所得二维特征图上各个部位的关注度以热力图的形式展现,是一种直观的可视化可解释分析方法。此外,对CSADI-Net和ML-CAM进行了测试,CSADI-Net在凯斯西储大学轴承数据集上的准确率可以达到97.32±0.12%并且可以完全分类大连大学实测轴承故障数据集,同时使用ML-CAM对CSADI-Net在两数据集各样本上绘制了类激活热力图,解释了网络运行机理,证实CSADI-Net具有高准确率,高抗噪性能,可解释性强等优点。
