Research on Short term Traffic Flow Prediction on Highways Based on LC-Transformer Model

工程科学与技术
随着城市经济的迅猛发展和私家车保有量的持续增加，城市交通流的准确预测对于缓解交通拥堵、提高出行效率以及保障交通安全有着重要意义。传统的交通流预测方法处理复杂的时空动态关系和天气、交通事故等外部因素影响时，往往依赖线性假设或静态模型，难以同时刻画交通流中非线性时空演化机制与多因素信息的融合特征，导致预测精度与泛化能力受限。为此，本文提出了一种基于改进Transformer模型，即LC-Transformer模型短时交通流预测方法。该模型结合了LSTM神经网络、CVAE条件变分自编码器以及交通历史事故数据 ...

双通道微环形腔结构传感器与微流通道的集成结构及其制作方法

本发明公开了一种双通道微环形腔结构传感器与微流通道的集成结构及其制作方法。该结构包含两个直波导微环耦合传感单元结构和两个微流通道。直波导微环耦合单元结构位于硅材料衬底上，在传感单元上面是两个由PDMS材料制作的微流通道，该微流通道方向垂直于直波导方向，两个微流通道各自对应一个微环形腔结构。现有该类传感器结构主要是基于单通道单微环耦合单元结构，单环谐振腔传感结构对环境温度比较敏感，在具体检测中，容易产生温度漂移现象，这极大的限制了该类传感器的实际应用 ...
