With the increment of data scale, many efficient single-machine algorithms of FIM, such as FP-growth and Apriori, cannot accomplish the computing tasks within reasonable time. As a result of the limitation of single-machine methods, researchers presented some distributed algorithms based on MapReduce and Spark, such as PFP and YAFIM. Nevertheless, the heavy disk I/O cost at each MapReduce operation makes PFP not efficient enough. YAFIM needs to generate candidate frequent itemsets in each iterative step. It makes YAFIM time-consuming. And if the scale of data is large enough, YAFIM algorithm will not work due to the limitation of memory since the candidate frequent itemsets need to be stored in the memory. And the size of candidate itemsets is very large especially facing the massive data. In this work, we propose a distributed FP-growth algorithm based on Spark, we call it DFPS. DFPS partitions computing tasks in such a way that each computing node builds the conditional FP-tree and adopts a pattern fragment growth method to mine the frequent itemsets independently. DFPS doesn't need to pass messages between nodes during mining frequent itemsets. Our performance study shows that DFPS algorithm is more excellent than YAFIM, especially when the length of transactions is long, the number of items is large and the data is massive. And DFPS has an excellent scalability. The experimental results show that DFPS is more than 10 times faster than YAFIM for T10I4D100K dataset and Pumsb_star dataset.","PeriodicalId":432109,"journal":{"name":"2017 IEEE 2nd Advanced Information Technology, Electronic and Automation Control Conference (IAEAC)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133881875","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}

It is a excellent method to solve this problem by adding the Euclidean Distance Metric based on landmark points as the penalty term to the Intensity-based metric in the registration. In this paper, an improved distance measure is proposed, which makes the local deformation more accurate than the Euclidean Distance Metric. In addition, for the multi-resolution registration model, an adaptive weight of metric method for multi-resolution registration is proposed, which makes the registration results better.","PeriodicalId":432109,"journal":{"name":"2017 IEEE 2nd Advanced Information Technology, Electronic and Automation Control Conference (IAEAC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133981750","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}

Compared to the conventional Vivaldi antenna (CVA), the width of the modified Vivaldi antenna aperture is reduced 38.05% by adding regular slot edges (RSE), which will prevent the antenna array from generating the grating lobes. Additionally, the RSE has improved the radiative features of antenna. It mitigates the side lobe level, overcomes the beam-squint at E-plane, and increases gain. The parameters of the CVA and CVA-RSE are optimized. The simulated impedance bandwidth (VSWR<2) is approximately from 7.85 GHz to 12 GHz for both of them. A comparison between the modified CVA-RSE and CVA at 12 GHz shows an improved gain of 10.8 dB, −13.3 dB of the Side Lobe Level (SLL), and 0 degrees of the Main Lobe Squint (MLS) at E-plane, in contrast with 9.5 dB of gain, −9.9 dB of SLL, and 2 degrees of the MLS at E-plane in the conventional Vivaldi antenna.","PeriodicalId":432109,"journal":{"name":"2017 IEEE 2nd Advanced Information Technology, Electronic and Automation Control Conference (IAEAC)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134328981","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}

We discuss FD spectrum sensing in non-time-slotted CRNs and study two work modes of SUs, transmitting-sensing (TS) mode and transmitting-receiving (TR) mode. SUs work alternately in two modes. In such a context, we analyze the sensing performance, probabilities of detection and false-alarm, and the SU throughput. An optimal time allocation strategy between TS and TR is proposed. And closed-form expressions of the allocation proportion of TR and TS are provided respectively, as with the detection and false-alarm probabilities.

Further, since user nodes have limited energy, it is necessary to consider fairness of cooperative relay network under the prerequisite of guaranteeing the average use time of all nodes. In this paper, we propose a relay node feedback function, and uses it to show degree of selfishness of the candidate nodes. According to the function, a strategy for relay selection and power allocation optimization based on the weighted fair energy is put forward. The results shown that the proposed method in the system significantly improves the inter-node energy consumption question of unfairness, the average energy consumption per load relay to each node, and finally to the energy balance of the entire network.","PeriodicalId":432109,"journal":{"name":"2017 IEEE 2nd Advanced Information Technology, Electronic and Automation Control Conference (IAEAC)","volume":"198200 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132612394","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}

There exist a lot of algorithms which most of them are based on the density of connections between groups of nodes. On the one hand, the error and lack of links may lead to great impact on the result of community detection. On the other hand, there are users with deep relation but without much communication, so the density of connections can't represent whether the users belong to the same community or not. With the network becoming more and more complicated, the traditional global method will cost much time and space. In this paper, we proposed a local method based on links and content, and the method focuses on particular users' communities. The results on Enron email dataset have shown the superior performance and accuracy rate of our proposed method in community detection.","PeriodicalId":432109,"journal":{"name":"2017 IEEE 2nd Advanced Information Technology, Electronic and Automation Control Conference (IAEAC)","volume":"183 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132775478","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 this paper, some RTSA technology, including digital phosphor (DPX)technology, frequency mask trigger (FMT) technology and DPX density trigger(DDT) technology, are used to design an electronic reconnaissance digital receiver. DPX technology achieves the digital accumulation of frequency spectrum, and can effectively analyze various signals of a period of time from frequency domain. FMT technology and DPX density trigger technology are novel trigging capturing methods for transient signals capturing. The proposed electronic reconnaissance receiver uses a FPGA (Field Programmable Gate Array) chip as the main processor.
