These transforms are vector quantization with principal components analysis, noise subspace projection, interference-and-noise-adjusted principal components analysis, convex cone analysis, and penalized discriminant analysis with principal components analysis. One approach to interference-and-noise-adjusted principal components analysis called signal-to-interference-plus-noise-ratio-based principal components analysis had the highest readability score according to a subjective judgment of 30 randomly selected individuals. However, convex cone analysis created a resultant image with the highest signal-to-noise ratio.","PeriodicalId":254758,"journal":{"name":"2008 IEEE National Aerospace and Electronics Conference","volume":"210 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121216518","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 calibrate the magnetic deviation, sensor errors caused by hard iron effect and initial heading of strapdown magnetometers are considered. In our approach, sensor output distortion due to the soft iron effect is ignored, which is relatively small. First, for the estimation of heading angle, system and measurement model is derived, which is nonlinear. Then particle filter and extended Kalman filter is introduced for performance comparison. The proposed algorithm for the integration of IMU and magnetometer is verified via numerical simulation in Matlab. Simulation result demonstrates accurate heading estimation error within 1 degree for both algorithms when there exists small initial heading error and hard iron effect, yet particle filter provides more robust and precise result than the extended Kalman filter in case the initial heading error and biases are large.","PeriodicalId":254758,"journal":{"name":"2008 IEEE National Aerospace and Electronics Conference","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131107123","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}

Lithographic masks were used to create 10-100 micron-sized arrays of enhanced hydrophilicity. Two such masks were used: (1) Polka Dot Filter having opaque squares and a transparent grid and (2) A metal wire-mesh having transparent squares and opaque grid. UV light selectively photodissociates the DNA film where it is exposed into smaller more hydrophilic fragments. UV-exposed films are then coated with a solution of a protein. The protein appears to selectively coat over areas exposed to UV light. We have also used interferometric lithography with UV light to accomplish patterning on the scale of 1 micron on DNA thin films. This technique has the potential to generate micro/nano arrays and vary the array-size. This paper describes the fabrication of these microarrays and a plausible application for fabricating antibody arrays for protein sensing applications.","PeriodicalId":254758,"journal":{"name":"2008 IEEE National Aerospace and Electronics Conference","volume":"202 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132641097","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 many approaches are considering mobile sensor nodes to deal with this problem. But making all the sensors mobile involves more signaling overhead for network maintenance. It is energy efficient to move the base station which has no power limitations. Also, there are many real life applications in which event based approach is more appropriate. In this paper, we propose an adaptive scheme for a mobile base station that moves according to the occurrence of events. We propose two optimization schemes: moving the BS towards the event centroid and moving the BS towards distance based weighted centroid. Simulation results show that moving the base station adaptively significantly prolongs the network lifetime.","PeriodicalId":254758,"journal":{"name":"2008 IEEE National Aerospace and Electronics Conference","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127259076","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}

Many countries and industries are developing autonomous and swarming UAVs for reconnaissance, surveillance, intelligence gathering, and target engagement and neutralization. The processes for effectively developing these systems are still in their infancy. Currently, little effort is focused on building simple agent rules with low-level SO systems communication in order to facilitate emergent behaviors. Note that only with the use of effective control structures can the full potential of these systems realized. Presented is an innovative new paradigm for developing SO-based autonomous vehicles. Using a formal design model, the Interactive Partially Observable Markov Decision Process, a full understanding of this SO domain is possible. With this design model and a focused effort on the minimization of computational and informational complexity, emergent entangled control hierarchies allow the SO rules to operate efficiently and effectively. This work extends the formal model decomposition technique, and in doing so ties in the information theoretic optimization to develop emergent structures. Preliminary computational results reflect limited success.","PeriodicalId":254758,"journal":{"name":"2008 IEEE National Aerospace and Electronics Conference","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129848983","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}
