The measured signal will be submerged by noise in complex environment, which makes it difficult to characterize targets, especially when the targets share the similar characteristics. Multi-sensor information fusion will improve characterization significantly and DS evidence theory is an effective approach in heterogeneous information fusion. However, evidence from multi-sensor information is always affected by subjective factors in the process of evidence fusion. In this paper, a new evidence fusion approach for improving characterization under complex environment is proposed. To characterize the heterogeneous images better, a concept of comprehensive credibility is introduced into the proposed approach and a new update rule of evidence is designed. Some experimental results show the efficiency and effectiveness of the proposed approach.","PeriodicalId":383024,"journal":{"name":"2014 IEEE Workshop on Electronics, Computer and Applications","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114506747","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}

STAT5 is composed of two highly homologous isoforms, STAT5a and STAT5b, that are encoded by two separate genes with 96% similarity in their amino acid sequences. However, studies have revealed that STAT5a and STAT5b play different roles in the progression of various types of cancer cells. We choose STAT5a as our target gene to silence. In our study, we constructed STAT5a-specific siRNA successful ly. It showed in the experiment that STAT5a-specific siRNA could actively inhibit STAT5a expression in mRNA level in MGC803 gastric cancer cel1 line, and decrease STAT5a protein expression. From this experiment, we obtain the best siRNA sequence of STAT5a, which may serve as a new strategy for investigating the mechanism of molecular STAT5a pathology of gastric cancer targeted tumor gene therapy.","PeriodicalId":383024,"journal":{"name":"2014 IEEE Workshop on Electronics, Computer and Applications","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128474215","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 system is wished to output qualified electric energy for those three-phase devices. The paper analyzed the wind turbine output characteristic and gained the relationships between output power and rotating angular velocity of the wind turbine. It searched for the optimal value of the rotating angular velocity, and tracked the maximum wind power with a method called changing step-size disturbance observation. The system could output the maximum electric power when the wind speed changed continuously, and it applied a low-pass filter behind the inverter to filter the harmonic generated when tracking the maximum wind power. The simulations proved that the system achieved expectant performance.","PeriodicalId":383024,"journal":{"name":"2014 IEEE Workshop on Electronics, Computer and Applications","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123596053","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}

Traditional image fusion algorithm has large amount of calculation and poor real-time performance, and does not carefully consider the influence of fusion rules of low-frequency component and the neighborhood characteristics of high-frequency component on the fusion at the same time, so it cannot get the ideal fusion effect. In order to solve the above problems, this paper proposed the nonlinear weighted multiband fusion algorithm which introduced the nonlinear weighted value. The simulation result shows that the calculated amount of the improved image fusion algorithm is significantly reduced, and the real-time performance is also increased significantly. Compared with the traditional Laplacian pyramid fusion algorithm, the precision of the image fusion is also improved effectively.","PeriodicalId":383024,"journal":{"name":"2014 IEEE Workshop on Electronics, Computer and Applications","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116262445","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}

If generation is smaller than load, system frequency will drop. When generation deficiency is too large, system frequency will decrease significantly which can lead to system blackout. To solve this frequency issue, proper underfrequency load shedding and islanding scheme is essential to prevent further deviation of system frequency from its nominal frequency. In this research, conventional underfrequency load shedding and islanding scheme using generator coherency approach are designed for Southern Sulawesi system, one of power system in Sulawesi, Indonesia. Southern Sulawesi system is not too large with peak load of about 800-1000 MW therefore easier to analyze performance of the method used in this research. The simulations were performed using DIgSILENT PowerFactory. Underfrequency load shedding and islanding scheme obtained can be applied to all scenarios simulated in this research with good performance.","PeriodicalId":383024,"journal":{"name":"2014 IEEE Workshop on Electronics, Computer and Applications","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116367401","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}
