方面级情感分析旨在预测给定句子中特定方面的情感极性。然而,现有大多数研究在对模型改进的过程中忽略了外部知识的有效利用,导致模型无法准确识别方面词的情感极性。另外,仅仅考虑有限的上下文信息可能会使得模型在分析方面词时忽略其在句子中的重要性和影响。基于此,提出了一种结合外部知识构建依赖增强矩阵的图卷积网络模型的方法(Dependency Enhancement Matrix GCN,DEMGCN)。该方法首先将词嵌入和位置嵌入进行融合,得到包含位置信息的句子特征向量;同时引入情感常识信息对原始依赖矩阵进行扩展,形成新的依赖增强矩阵DEM,这在一定程度上突出了情感词的权重信息,并且弥补了原始依赖树无法捕获边缘标签的不足。此外,构建了一个信息交互网络(information interaction Network,iiN),通过方面词与上下文之间的交互来提取全局的句子信息。最后,在5个基准数据集上的实验结果显示,与基线模型相比DEMGCN在准确率和Macro-F1上分别提高了1~2百分点。

77 GHz毫米波雷达因其体积小和分辨率高等特点在无人驾驶车辆领域具有广阔的应用前景。天线罩作为毫米波雷达系统的重要组成部分,能有效防御恶劣环境对雷达系统工作性能的影响,但天线罩在保护雷达系统的同时会在雷达电磁波传播路径上引入介质,从而造成天线辐射性能的衰减。为了改善天线罩对雷达天线辐射性能的影响,本文提出了一种基于77 GHz毫米波角雷达天线罩的优化设计方法。该优化方法以遗传算法(GA)作为优化算法,运用MATLAB将GA与高频仿真软件HFSS结合,通过优化拱形天线罩横截面圆弧的圆心角和天线罩与天线的垂直间距,使雷达天线在其工作频段内具有高增益和低旁瓣的同时,增大天线3 dB方位面波束宽度,提高毫米波角雷达视场角的宽度。仿真结果表明,优化天线罩后阵列天线的3 dB方位面波束宽度增大了37°,工作带宽增大了1.04 GHz,俯仰面最大旁瓣降低了1.02 dB。分析结果表明,基于优化方法设计的天线罩能够有效增大毫米波角雷达阵列天线的视场角,拓宽该雷达天线阵列的工作频带,并降低其俯仰面最大旁瓣。77 GHz毫米波角雷达天线罩数值算例验证了该优化方法的有效性。

在短波令牌环组网过程中,由于节点入环的随机性,形成的令牌传递顺序存在多余的中继,导致令牌控制开销过大,网络时延增加,从而影响到整个网络的性能.为了解决上述问题,本文提出了一种自适应蚁群算法优化的短波令牌环协议.首先,由一轮令牌传递得到网络全部节点的距离矩阵,用来构建初始解空间.其次,通过蚁群算法求解每轮周游的最短路径并对各节点的信息素强度进行更新.最终,经过多次迭代比较后,即可得到最优传输路线.实验表明,优化后的协议重组了相邻节点间前驱后继的关系,省去冗余的令牌转发过程,最大化减少了整个环周期长度,从而节省了令牌绕环的时间.同时在网络平均时延和总控制开销方面明显优于现有协议,验证了该协议的可用性和优越性.
