Profiling Pumped Storage Power Station via Multi-Sequence Joint Regression 多序列联合回归分析抽水蓄能电站
Wancheng He, Xun Li, Kaitao Zhou, Junheng Huang, Shuang Tang
Suggesting personalized tags to the Pumped storage hydropower plants (PSHPs) towards purchase requirements forecasting plays a key role in achieving the smart power grids. However, current tag suggestion solutions only take single sequence into consideration, and predict single label for PSHPs, resulting in suboptimal forecasting accuracy. In this paper, we propose a novel Multi-Sequence Joint Regression (MSJR) model towards the task of PSHP tagging. In particular, MSJR exploits multi-sequence as input for collaborative perception purpose, and a multi-label regression module is built in the MSJR framework to predict tags describing the purchase requirements of PSHPs. Our encouraging experimental results on a real-world dataset, crawled from the ERP system of the State Grid Xin Yuan, validate the superiority of the our MSJR over several existing tagging suggestion methods.
为抽水蓄能电站提供个性化标签,进行购买需求预测,是实现智能电网的关键。然而,目前的标签建议方案只考虑单个序列,并预测pshp的单个标签,导致预测精度不理想。在本文中,我们提出了一种新的多序列联合回归(MSJR)模型来完成PSHP标记任务。特别地,MSJR利用多序列作为协同感知目的的输入,并在MSJR框架中构建了多标签回归模块来预测描述pshp购买需求的标签。我们在一个来自国家电网鑫源ERP系统的真实数据集上取得了令人鼓舞的实验结果,验证了我们的MSJR比现有几种标注建议方法的优越性。

Attribute Information Extracting Method for Air Quality Assessment of Buildings
Xiaozhi Du, Yurong Duan, Wei Huang
Extracting architectural elements from Industry Foundation Classes (IFC) files plays an important role on indoor air quality assessment. However, the traditional methods may extract useless instances and miss some necessary information, which results in poor air quality assessment. To address the above issues, this paper proposes an attribute extraction method for air quality assessment from IFC files, called as IFC-AAE. First the instances of the IFC file are preprocessed to remove the redundancies. Next the entity instances related to air quality assessment are extracted and then classified based on floors. Finally, the attribute information of these entities is extracted according to their reference relationship. The experimental results show that the IFC-AAE method is superior than the previous methods. Compared with the IFC file analyzer, the IFC-AEE method generates fewer invalid data. Compared with the Map-based extract method, the IFC-AEE method has an improvement by 4.78% on the precision rate on average.
从工业基础类(IFC)文件中提取建筑元素对室内空气质量评价具有重要意义。然而,传统的方法可能会提取出无用的实例,遗漏一些必要的信息,从而导致空气质量评价效果不佳。针对上述问题,本文提出了一种从IFC文件中提取空气质量评价属性的方法,称为IFC- aae。首先,对IFC文件的实例进行预处理以消除冗余。接下来,提取与空气质量评估相关的实体实例,然后根据楼层进行分类。最后,根据实体的引用关系提取实体的属性信息。实验结果表明,IFC-AAE方法优于以往的方法。与IFC文件分析器相比,IFC- aee方法产生的无效数据更少。与基于地图的提取方法相比,IFC-AEE方法的平均准确率提高了4.78%。

Integrated Navigation Algorithm for Intelligent USVs with Unstable GPS GPS不稳定的智能无人潜航器组合导航算法
Hang Li, Yi Lin, Yiyang Duan, K. Si, Peng Li
In complex marine or unpredictable combat environments, there may be unstable and even loss of GPS for the integrated navigation system of unmanned surface vehicles (USVs). This paper analyzes the error model of loose combination navigation, and proposes a method of the recurrent neural network (RNN) aided inertial navigation system (INS). When the GPS signal is interrupted, the RNN is used to correct the navigation error of the INS. Simulation results show that in case of unstable GPS, the RNN-aided navigation system can ensure rapid convergence of error, and the east position error can be kept within a satisfactory scope. Compared with the single inertial navigation system, the navigation accuracy is effectively improved.
在复杂的海上或不可预测的作战环境中,无人水面车辆(usv)组合导航系统可能存在GPS不稳定甚至丢失的问题。分析了松散组合导航的误差模型,提出了一种递归神经网络辅助惯性导航系统的方法。当GPS信号中断时,利用RNN对惯导系统的导航误差进行校正。仿真结果表明,在GPS不稳定的情况下,rnn辅助导航系统能够保证误差的快速收敛,使东侧定位误差保持在令人满意的范围内。与单惯性导航系统相比,有效地提高了导航精度。

With the development of information technology, the traditional teaching model has emerged problems such as simply imparting knowledge and failing to meet students' personalized learning. Big data technology will provide richer learning resources, teaching methods and learning styles to drive new changes in education. In the era of big data, the blended teaching mode makes full use of the information-based teaching platform to break the drawbacks of the traditional teaching mode, which is of great value and significance to the reform of China's teaching mode.

Research on ShadowsocksR Traffic Identification Based on DART Algorithm 基于DART算法的ShadowsocksR流量识别研究
Qingbing Ji, Xiaoyan Deng, Lulin Ni
Shadowsocks (SS) is a new popular anonymous communication software in recent years. The traffic generated by SS is very difficult to identify. There is also an enhanced version of SS, called ShadowsocksR(SSR), which can disguise SS traffic as traditional protocol traffic, such as HTTP traffic, TLS traffic, etc. This makes the identification of SS traffic more difficult. In reference [16], an identification method of HTTP camouflaging traffic of SS is proposed for the first time. Here, a new identification method is proposed based on dart algorithm. Compared with reference [16], this method has more types and wider range of SSR obfuscated traffic, and has better identification effect for recent SSR obfuscated traffic, with the accuracy, the recall and the precision are all above 98.5%.

Lei Shao, Heyong Yuan, Xinfeng Wang, Wengang Liu, Qiao Zhang
Aiming at the problem of large deformation and soft fracture of soft rock in deep roadway, through theoretical analysis of deformation and failure characteristics of surrounding rock of deep roadway, the space-time evolution law of deformation and failure of surrounding rock of deep soft rock roadway is obtained by FLAC3D software simulation. The results show that: The deformation of surrounding rock in deep soft rock roadway is characterized by roof subsidence, two sides moving inward and floor bulging. Under the action of high stress, the deformation of surrounding rock of soft rock roadway has a certain timeliness. The deformation and failure of surrounding rock of roadway is a changing process with time. The damage degree of roof, floor and two sides of roadway increases with time, and finally tends to a stable state. The deformation presents a distribution law that the de-formation of floor is larger than that of roof and convergence of two sides.

This method has implications for follow-up studies of sea states, it can provide the basis for classification for the data processing of self-contained optical measuring instruments.","PeriodicalId":396802,"journal":{"name":"2021 7th Annual International Conference on Network and Information Systems for Computers (ICNISC)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114543201","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}
