The statistical classifiers used in these data fusion approaches are also transformed by integrating the contextual information from neighboring pixels, to improve the accuracy of a fuzzy-logic-based fusion scheme. A decision level fusion approach was developed by Gokaraju et. al, 2012, which combines statistical methods and machine learning techniques. Here, each data sample is integrated through separate classifiers such as empirical methods and support vector machines (SVMs) and then used a Probabilistic Neural Network (PNN) to fuse the decisions for a unified consensus decision. The data fusion approach consists of either pixel-level or feature-level data fusion in combination with machine learning techniques for classification. The intermediate results of the disaster management studies, such as levee land-slide and tornado debris assessment using data fusion techniques, are presented in this paper. For levee landslide studies, we used the multi-temporal datasets of air-borne synthetic aperture radar sensor (UAVSAR). For Tornado disaster studies, we used multi-source and multi-temporal datasets of both synthetic aperture radar sensor (RADARSAT-2) and multispectral sensor (RapiEye) datasets. The results of data fusion approach outperformed the non-data fusion techniques in both studies with kappa accuracies of 82.8% and 72%.","PeriodicalId":368197,"journal":{"name":"SoutheastCon 2017","volume":"21 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":"131836316","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}

Without a startup circuit for control of propagation, the direction of traveling wave is mostly nondeterministic. The direction is defined by the least resistance path of the transmission line. Startup circuits have been demonstrated to work for low frequencies of operation. The drawback of such circuits includes an increase in the power budget. Startup circuits are also not ideal for high frequency applications because of the parasitic capacitance they introduce. Presented in this paper is an offset technique for direction control. This technique involves connecting at least one of the gain stages through a segment of transmission line. The transmission line introduces a phase shift between the input and output of the gain stage and creates two signal amplification paths at the start of oscillation. Conventionally, the current injected by the gain stages will follow the path of higher amplification, thus defining the direction of propagation.","PeriodicalId":368197,"journal":{"name":"SoutheastCon 2017","volume":"65 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":"114288822","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}

Such digital implementations of non-Foster circuits have shown promise in addressing common design challenges, such as stability, that may be more difficult to control in analog non-Foster circuits. Furthermore, a digital approach offers inherent potential advantages in applications such as software-tunable or adaptive digital implementations of negative RLC or positive RLC circuits.

The proposed design improves the DC-DC converter efficiency by 9.25% when compared to conventional maximum-power-point tracking systems over a wide range of input power and optimal load resistances, allowing for the harvesting of more energy and greater power delivered to the load.
