How to monitor the radio signal in space real-timely and efficiently is a hotspot and difficult point of the research about spectrum sensing technology. In order to improve the experimental teaching effect and students' understanding of cognitive radio technology, this paper builds a spectrum sensing platform based on LabVIEW and USRP, which is useful to train students' practical ability and innovation ability of spectrum sensing technology. By using energy detection method, we carry out dynamic spectrum sensing experiment and spectral scanning experiments. Dynamic spectrum sensing experiments show the spectrum usage in the 95MHz-105MHz and 950MHz-960MHz frequency bands. Spectrum scanning experiments are conducted on the 70MHz-170MHz and 900MHz-1GHz frequency bands and show the spectrum usage of that two bands.","PeriodicalId":285726,"journal":{"name":"2017 4th International Conference on Systems and Informatics (ICSAI)","volume":"274 1-2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116849006","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}

Recently, the development of deep learning technology has provided a new direction. This paper introduces a new method of the seizure detection based on EEG signal using the short time Fourier transform(STFT) and convolution neural network(CNN). And the paper verifies the feasibility of this method through the actual research data and parameter setting. Afterwards, the method of single threshold is adopted to combine the multi-channel results. Then, the comparison with the classical method using the support vector machine(SVM) has been done, which shows that the approach presented in this paper is better. And the experimental result on single channel is that the average accuracy is 86%. In addition, the method of the multi-channel could increase the average accuracy to 90% and the average true positive rate(TPR) to 96.5% while decrease the average false positive rate(FPR) to 7%. All of those indexes reveal the high performance and stability of the approach for the epileptic seizure detection.","PeriodicalId":285726,"journal":{"name":"2017 4th International Conference on Systems and Informatics (ICSAI)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117023246","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}

The improved algorithm outperforms the original for over 73% of the 50-dimensional CEC 2014 problems and is worse for less than 17% of the problems when comparing using a Wilcoxon rank-sum test. The evolutionary automatic programming system ADATE that is used in this paper systematically searches for better programs by evaluating millions of candidate programs. The candidates are graded by first evaluating on a small training set consisting of five synthetic optimization problems, with well performing candidates being evaluated more extensively on a larger and more computationally expensive validation set with 100 problems. Thus, we use one evolutionary algorithm to rewrite the source code of another evolutionary algorithm. The results show that the techniques introduced in this paper are capable of improving the heuristics of contemporary numerical optimization algorithms.","PeriodicalId":285726,"journal":{"name":"2017 4th International Conference on Systems and Informatics (ICSAI)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129474244","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}

Therefore, the virtual power plant will participate in the regulation market for those batteries and gas generators. However, uncertainty of intermittent energy in VPP will damage the performance score in settlement and decrease the benefit of VPP. In order to give full play to the high-quality regulation services of VPP, this paper introduces a regulation mechanism for VPP, and we propose a calculation method of VPP's frequency performance. To reduce the influence of fluctuation of intermittent power and load on VPP's regulation performance, an improved VPP regulation control strategy is proposed. Finally, the results show the effectiveness of the control strategy.","PeriodicalId":285726,"journal":{"name":"2017 4th International Conference on Systems and Informatics (ICSAI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126664035","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}

However, oil spills and lookalikes are characterized by dark spots on SAR images. They have similar or identical backscattering coefficients and gray values, which are easy to produce confusion. Aiming at this problem, this paper proposes a deep learning model-Deep Belief Network (DBN), which uses DBN to distinguish oil spills, lookalikes and water. In the experiment, 900 images were collected from the three SAR oil spill images to form a small sample space dataset. The two kinds of texture features such as Tamura and Gray Level-Gradient Co-occurrence Matrix are extracted, and the feature vector with good distinguishing features is selected as the input data of the model. Finally, the classification results are compared with the traditional machine learning method (BP, SVM). The experimental results shows that the DBN model proposed in this paper is superior to these classifiers in classification accuracy.","PeriodicalId":285726,"journal":{"name":"2017 4th International Conference on Systems and Informatics (ICSAI)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126807661","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}

However there are still something to be improved. First of all, considering the large quantity of music, it is difficult for users to search for a song with full information. Second, due to the easy-interference of the mobile network, it may cause a bad experience because of the delay when playing music. In this paper, we designed a streaming media player based on Android to improve these deficiencies. On the one hand, two transfer methods were designed and can be selected by users to fit the network situation. On the other hand, two fuzzy searching methods was compared in this paper, and the Levenshtein distance was finally adopted to retrieve a song with partial information. Furthermore the system was programmed with the Java language, Android system framework and SSH (Struts + Spring + Hibernate) framework. Some necessary modules was contained in the system such as user center, logging in, registering and others. The test results demonstrated that the player performances well in various network situations. The Levenshtein algorithm can find out all of songs which matching the input information with less time and the result of fuzzy searching can be sorted by the correlation value between the search results and the input information.","PeriodicalId":285726,"journal":{"name":"2017 4th International Conference on Systems and Informatics (ICSAI)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129236815","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}
