小目标检测一直是目标检测领域的难点,针对卷烟厂卷包车间摄像头安装位置较高、小目标检测精度低和总体检测精度较低的问题,提出了一种改进的YOLOv8n目标检测算法YOLOv8n-FIAL。首先使用添加通道重排机制的C2fg模块代替原本C2f模块,提高特征学习能力,使用自适应通道特征融合模块代替YOLOv8n算法Neck部分的Concate操作,使特征融合更加充分;然后增加小目标检测层,提高小目标检测精度,降低漏检率;最后使用Focal-EIOU损失函数替换原来的CIOU损失函数,平衡锚框与真实框重叠较大的高质量锚框的数量远少于低质量锚框训练实例不平衡的问题。实验结果表明,在自制的卷烟厂工人违规作业数据集上,所提出的YOLOv8n-FIAL检测方法相比原始的YOLOv8n方法的总体平均精度均值提升了7.6%,对口鼻、手拿手机和衣服领口这3类小目标平均精度均值提升最大,分别提升了8.3%,8%和9.6%;在公共数据集VOC2007上,YOLOv8n-FIAL算法相比YOLOv8n算法的总体平均精度均值提升了1.6%。

海陆风电的大规模开发并网给电网的稳定带来挑战,微电网是解决分布式发电系统优化运行问题的有效途径。综合考虑微电网群的系统运行经济性和碳排放环境效益,提出了基于分布式共享储能的交互型微网群低碳日前调度模型。首先考虑风电的不确定性,基于传统实时电价提出跟随微网净负荷的定价策略;随后根据微网群用户的负荷特点定义了价格型和激励型需求响应用户满意度;然后通过生命周期评价方法划分系统运行环节的碳排放链,引入阶梯碳交易机制构建碳排放成本模型;最后基于微网群的交互运行,利用分布式储能资源进行日前优化调度。仿真算例表明:对比独立型微网群,所提出的交互型调度模型消除了原有的弃风情况,碳排放量减少32.14 t、系统运行总成本缩减15.05%。

随着可再生能源的大规模开发、高比例并网,虚拟电厂逐渐成为充分发挥新型电力系统经济-环境效益的关键技术之一,文章重点研究了电氢耦合虚拟电厂多目标优化问题。首先,构建了含分布式风光机组、微型燃气轮机、分布式储能、柔性负荷的电氢耦合虚拟电厂。其次,运用多主体全生命周期法计算得到虚拟电厂构成组件的碳排放系数,并将其与阶梯式碳交易机制联合引入优化模型中。然后,以系统内运行成本最小和二氧化碳排放量最低为目标函数,通过赋权法将多目标优化转为单目标优化。最后选取华北某园区夏季、过渡季、冬季3个典型场景为算例分析验证所构建模型的有效性,算例结果表明该模型能兼顾虚拟电厂内部各设备主体运行的经济利益和环境效益。

The abnormal aggregation of α-synuclein (α-Syn) is thought to be closely associated with Parkinson's disease, but the pathogenesis is still unclear. In this review, we survey the latest development in the molecular mechanism of abnormal α-Syn aggregation, especially in the aspects of the core sequences, aggregation inhibitors, structural transformation and filament morphologies. By exploring the mecha-nism of α-Syn aggregation, we will have a better understanding of the disease pathogenesis, and de-velop strategies for preventing and treating this severe disease.
