The system uses a line scanning lidar to scan a stockpile with high-precision sensors to measure the position and attitude of itself in real time, and then integrates discrete scanning points to form a 3D point cloud of the stockpile. In data processing, the algorithm was optimized according to the measurement characteristics of the line scanning lidar and the structural characteristics of the stockpile. Noise reduction for the scanning points and ground points removal was performed concurrently in the measurement process. In addition, the point cloud was projected onto a 2D plane for a quick Delaunay triangulation, thus improving the speed of 3D stockpile modeling effectively. Field experiments showed that the system can complete 3D modeling of large stockpiles within a few minutes. The modeling time mainly depends on the walking speed of the operator who circles around the stockpile, and the waiting time for the 3D modeling after the measurement is generally less than 30s.","PeriodicalId":409693,"journal":{"name":"2019 International Conference on Intelligent Computing, Automation and Systems (ICICAS)","volume":"28 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":"132491295","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}

To protect the function pointers, we propose a novel solution called PointerLock. To avoid being tampered with by the attacker, PointerLock restricts the writing operation on the function pointers with the support of access control on the page. PointerLock centralizes the application's function pointers to a few pages, and these pages are only readable by default. Only when the application want to modify the pointer, PointerLock makes the page writable where the function pointer is located in. This reduces the time window of attacking the function pointer. To prevent an attacker from tampering with other function pointers on the same page as function pointers, PointerLock performs the necessary checks on the page before they are used again. The prototype system of PointerLock was built in Fedora 21 with a 3.17.6 kernel. Two system calls are implemented in kernel space, and six interfaces are developed for users in the form of dynamic link libraries in user space. The tests show that PointerLock is capable of preventing the attacker from tampering with the function pointers, and it does not introduced an overheavy performance.","PeriodicalId":409693,"journal":{"name":"2019 International Conference on Intelligent Computing, Automation and Systems (ICICAS)","volume":"2012 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":"114450260","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}

In actual industrial environments, it is difficult to collect enough real damaged samples, but artificial damaged samples are easy to obtain. In this paper, a novel transfer learning method with convolutional neural network (CNN) from artificial damage to real damage for bearing fault diagnosis is proposed. Firstly, the CNN model is constructed and pre-trained by huge and easily obtained artificial damaged samples. Then, parameters of some layers from the pre-trained CNN model are frozen to save the same feature between artificial damaged samples and real damaged samples. Finally, a small number of real damaged samples are used to fine-tune the model. Experiments on an open bearing fault database showed that the proposed method can not only improve the diagnosis accuracy in the real damage dataset, but also save training time and samples. The superiority of the proposed method is also proved by comparing with other classical methods and visualizing the learned features of the networks.","PeriodicalId":409693,"journal":{"name":"2019 International Conference on Intelligent Computing, Automation and Systems (ICICAS)","volume":"34 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":"132847650","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}

As an important platform for two-way interaction between the user side and the power system, the social network plays an important role in the development of the smart grid. The structural parameters of the social network include the total number of users and the network density. The network density is reflected by the number of neighbor nodes of the network node and the strength of the connection. Determining the total number of users in the network is beneficial to the smart grid for power allocation. Power system load peaks, insufficient power supply, etc. Deter-mining network density helps speed up the popularization and promotion of smart grid technology and helps to understand the social influence of users in social networks. Offline social network topologies are usually selected by interviewees and then asked to list their neighbors. This paper proposes an inference technique based on so-called “fixed choice” surveys, which requires the interviewee to enumerate all the strong ties and a fixed number of weak ties(e.g.,two or ten). Then use the method of moments to infer the total number of users and the network density of the social network. Experiments using simulated data show that the proposed inference algor-ithm performs well in various network topo-logies and measurement scenarios, and the est-imates obtained are significantly more accu-rate than the estimates obtained directly using the coarse observation network.","PeriodicalId":409693,"journal":{"name":"2019 International Conference on Intelligent Computing, Automation and Systems (ICICAS)","volume":"60 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":"124943952","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}

Multi-label conflicts can reduce the recognition efficiency of RFID systems. Reasonable anti-collision algorithms have become a hot issue in RFID technology. The application of CDMA technology to the RFID system proposed in this paper to achieve multi-channel communication can improve the reading efficiency and alleviate the conflict of labels. It can also solve the problem that multiple readers interfere with each other in a dense environment. Its advantages are mainly due to the simultaneous transmission of information by multiple channels brought by orthogonal sequences. Spreading and despreading of orthogonal spread spectrum is the key to digital system design. This paper mainly explains the way to implement this part, the process of despreading using the correlation algorithm of orthogonal sequence, and the methods to find the synchronization information of EPC code in the despreading process.","PeriodicalId":409693,"journal":{"name":"2019 International Conference on Intelligent Computing, Automation and Systems (ICICAS)","volume":"1 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":"130242080","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}

Furthermore, link failures will have a great impact on the normal operation of PLC network and the causes of link failures are diverse. Therefore, rapid fault location is extremely important for PLC. Fault localization generally requires complete knowledge of the network topology which is usually unknown and needs to be learned by topology inference algorithms. However, it is difficult for routers to collect complete topology information for topology inference. We propose an algorithm based on partial information for topology inference to help the PLC to detect and locate faults normally. The inference algorithm first builds a virtual topology, overestimates the number of network components, and then repeatedly merges the links in this topology to infer the structure of the real network. We conducted simulations and compared our algorithm with the most advanced inference algorithms. The results show that compared with other methods, the topology structure of our inference algorithm significantly improves the performance of the fault location.","PeriodicalId":409693,"journal":{"name":"2019 International Conference on Intelligent Computing, Automation and Systems (ICICAS)","volume":"1 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":"127435686","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}
