摘要：Valveless piezoelectric pump is widely used in the medical,however,there is a general and difficult problem to be solved:Low vortex and large flow rate are not compatible,resulting in the blood prone to thrombosis during blood *** this paper,a new valveless piezoelectric(PZT)pump with streamlined flow tubes(streamlined pump)is *** design method and the working principle of the pump are *** velocity streamlines are simulated,and the results demonstrate that there are no obvious vortexes in the flow tube of the streamlined *** prototype pumps(two cone pumps and three streamlined pumps)are designed and fabricated to perform flow rate and flow resistance *** experimental results illustrate that the maximum flow rate of the streamlined pump is 142 mL/min,which is 179%higher than that of the cone piezoelectric pump,demonstrating that the streamlined pump has a large flow rate *** research provides an inspiration for future research on simple structure,low vortex and large flow rate volume-type pumps,and also provides a useful solution for thrombosis preventing.

摘要：在开展多模态情感分析的过程中,需要考虑2方面的关键信息:一是每种模态的内部信息,二是各模态之间的交互信息。针对如何有效地捕获以上核心信息的问题,提出一种记忆迭代网络模型。将每种模态的序列数据分别输入到其各自的循环神经网络以及注意力机制模块,处理后将所有模态序列级联并送到记忆迭代模块进行迭代处理,迭代结束后将数据经过完全连接层,降低维度后进行分类。在公开的数据集CMU-MOSI、ICT-MMMO以及YouTube上进行的实验表明,记忆迭代网络模型的准确率和F1值均有所提升。
