Identification of Critical-to-quality Characteristic in Complex Products Based on the Adaptive-Lasso Method 基于自适应套索方法的复杂产品关键质量特征识别
Wei Wang, Wenfeng Wang, Erqi Ding
Targeting the problem of the redundancy in complex product quality characteristics, the Adaptive-Lasso method is introduced into the identification of Critical-to-quality Characteristic. By using the Adaptive-Lasso method to filter variables, reduce the dimensions of the original quality data sample set, and obtain the order of the correlation between the quality Characteristics in the sample set and the quality category, the quality Characteristics with the highest classification correct ratio are selected to form the Critical-to-quality Characteristic subset. On this basis, the classification correct ratio of the selected Characteristic subset is tested by using the support vector machine. The example shows that compared with the traditional ReliefF method and Lasso method, this method can effectively remove the irrelevant and redundant features in the original data set to achieve the purpose of identifying the Critical-to-quality Characteristic.
针对复杂产品质量特征中存在的冗余问题,将自适应lasso方法引入到关键质量特征的识别中。通过Adaptive-Lasso方法对变量进行过滤,对原始质量数据样本集进行降维,得到样本集中质量特征与质量类别之间的相关阶数,选择分类正确率最高的质量特征组成Critical-to-quality特征子集。在此基础上,利用支持向量机测试所选特征子集的分类正确率。实例表明,与传统的ReliefF方法和Lasso方法相比,该方法可以有效地去除原始数据集中不相关和冗余的特征,达到识别临界质量特征的目的。

Object Detection Algorithm based on Dense Connection 基于密集连接的目标检测算法
Pang Zhihao, Chen Ying
The way that information propagates in neural networks is of great importance. In this paper, we propose a connectivity pattern: dense connection, aiming to solve object detection algorithm YOLO-Tiny with less convolutional layers, low feature utilization rate, low precision and poor detection of small objects. We integrate dense connection into YOLO-Tiny, increasing its convolutional layers and improving the feature extraction network. Improved network extracts feature maps and fuses the feature maps by using the Dense Block module. Detection network completes the classification and location at different scales with different anchor boxes. We tested improved network on the Pascal VOC dataset. The experimental results show that our network has improved accuracy by 15% compared with the original algorithm. Although the detection speed has increased, it can still meet the requirements of real-time detection. Compared with the YOLO-Tiny model, our model size only increases by 9.8. MB, compared to the YOLO model, the model size is about 1/5 of the original.
信息在神经网络中的传播方式非常重要。本文提出了一种连接模式:密集连接,旨在解决目标检测算法YOLO-Tiny卷积层数少、特征利用率低、精度低、小目标检测能力差的问题。我们将密集连接集成到YOLO-Tiny中,增加了它的卷积层,改进了特征提取网络。改进后的网络利用Dense Block模块提取特征图并融合特征图。探测网络利用不同的锚箱完成不同尺度的分类定位。我们在Pascal VOC数据集上测试了改进后的网络。实验结果表明,与原算法相比,该网络的准确率提高了15%。虽然检测速度有所提高,但仍能满足实时检测的要求。与YOLO-Tiny模型相比,我们的模型尺寸只增加了9.8。MB,与YOLO模型相比,模型尺寸约为原模型的1/5。

Deterministic hierarchical joint remote state preparation using partially entangled quantum channel 利用部分纠缠量子信道制备确定性分层联合远程态
Na Chen, Shuangshuang Shuai, B. Yan
In this paper, we propose a novel scheme for deterministic hierarchical joint remote state preparation (HJRSP). Two senders and three receivers are involved. One sender has the amplitude information of the target state to be prepared at the receiver's port, while the other one has the phase information. There is a hierarchy among the receivers concerning their powers to reconstruct the target state. 6-particle partially entangled state is used as the quantum channel. Participants perform projective measurements under elaborate measurement bases. According to their measurement results, the receiver reconstructs the target state by means of appropriate unitary operation. The higher-power receiver reconstructs the target state independently, and the lower-power receiver reconstructs the target state if and only if all the other receivers help him (her). Different from the previous HJRSP scheme utilizing partially entangled channels, auxiliary qubit is not required in our scheme, and unit success probability can be achieved. It is shown that the success probability is independent of the parameters of the partially entangled quantum channel.
本文提出了一种确定性分层联合远程状态准备(HJRSP)的新方案。涉及两个发送者和三个接收者。一个发送方具有在接收方端口准备的目标状态的幅度信息,而另一个发送方具有相位信息。接受者对目标状态的重构能力是有等级关系的。采用6粒子部分纠缠态作为量子通道。参与者在精心设计的测量基地下进行投影测量。接收机根据它们的测量结果,通过适当的统一运算重建目标状态。高功率接收者独立地重建目标状态,低功率接收者重建目标状态当且仅当所有其他接收者帮助他(她)。与以往利用部分纠缠信道的HJRSP方案不同,本方案不需要辅助量子比特,可以实现单位成功概率。结果表明,成功概率与部分纠缠量子信道的参数无关。

High power microwave interference effect of radar system 雷达系统的高功率微波干扰效应
Changan Kou, Xiaobin Tang, Kang Shao, Jiangling Liu
With the gradual entry of high-power microwave weapons into the battlefield, the accurate evaluation of high-power microwave interference effects has increasingly important practical significance. Firstly, a radar simulation system based on nonlinear RF front-end is established. The interference effect of high-power microwave on radar nonlinear RF front-end and pulse compression processing module is analyzed. It is concluded that whether the interference signal covers the echo signal in the time domain is the main factor of the interference. Secondly, the same-frequency interference signal with different parameters is injected into the system together with the target echo signal to calculate the target detection probability of the radar system under the disturbed state. Based on the probability evaluation criterion and the least squares method, the data is analyzed, and the mathematical model of the interference pulse repetition interval and the radar target detection probability is fitted. The results show that when the power is large enough, the pulse repetition interval of the interference signal and the target detection probability constitute a power function relationship, and the function parameters are linearly related to the interference signal pulse width. When the pulse repetition interval of the high-power microwave and the radar transmission signal reaches a certain ratio, effective interference can be achieved. Under the same duty cycle, the interference effect of the interference signal with high pulse repetition rate is obviously stronger than that of the high pulse width. The suppression of high-power microwaves can significantly reduce the radar detection performance. The model can be used to optimize the interference pulse design and the prediction and evaluation of interference effects.
随着大功率微波武器逐步进入战场,准确评估大功率微波干扰效果具有越来越重要的现实意义。首先,建立了基于非线性射频前端的雷达仿真系统。分析了大功率微波对雷达非线性射频前端和脉冲压缩处理模块的干扰影响。认为干扰信号在时域上是否覆盖回波信号是影响干扰的主要因素。其次,将不同参数的同频干扰信号与目标回波信号一起注入系统,计算雷达系统在扰动状态下的目标探测概率;基于概率评价准则和最小二乘法对数据进行分析,拟合了干扰脉冲重复间隔与雷达目标探测概率的数学模型。结果表明,当功率足够大时,干扰信号的脉冲重复间隔与目标检测概率构成幂函数关系,函数参数与干扰信号脉宽呈线性关系。当大功率微波与雷达传输信号的脉冲重复间隔达到一定比例时,可以实现有效干扰。在相同占空比下,高脉冲重复率的干扰信号的干扰效应明显强于高脉宽的干扰信号。对高功率微波的抑制会显著降低雷达的探测性能。该模型可用于干扰脉冲的优化设计和干扰效果的预测与评价。

The miniaturization characteristic of the antenna is obtained by folding the radiation patch. And the slots etched on the patch are optimized to improve the impedance bandwidth. This presented antenna with the dimension of 15× 20 mm2 and has an operation bandwidth of 3.10 GHz-5.74 GHz (59.7%). Finally, the positioning performance of the antenna was measured in the UWB positioning system and a positioning accuracy of 4 cm is obtained.","PeriodicalId":164163,"journal":{"name":"2019 IEEE 4th Advanced Information Technology, Electronic and Automation Control Conference (IAEAC)","volume":"329 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123322249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
