In this paper a novel substitutive Pan sharpening method using PCA and contourlet transform is proposed. The proposed method provides novel tradeoff solution between the spectral and spatial fidelity and preserves more detail spectral and spatial information. Also, new substitution based image fusion rules are proposed. Proposed method is applied on registered Panchromatic and Multispectral images and simulation results are compared using standard image fusion parameters. The simulation results of proposed method also compared with four different standard Pan sharpening methods available in literature. It has been observed from simulation results that proposed algorithm preserves better spatial and spectral information and better visual quality compared to earlier reported methods.","PeriodicalId":206392,"journal":{"name":"2011 Nirma University International Conference on Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121052737","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 Artificial Neural Network (ANN) based sensorless rotor position estimation technique is presented to fulfill the requirement of the position feedback for the SRM. MATLAB simulink environment is used to design a neural network and to simulate the proposed sensorless method which shows satisfactory result. An idea is presented to reduce the number of neuron for mapping the magnetic characteristics of the neural network which can reduce the complexity and computation burden without much affecting the performance of the SRM. Region of interest of the magnetic characteristics is described & discussed first time in this paper which helps to analyse a region of the magnetic characteristics where the significance of accuracy of the rotor position estimation is more compared to exterior region.","PeriodicalId":206392,"journal":{"name":"2011 Nirma University International Conference on Engineering","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114427649","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 damping functions of the UPFC with various alternative control signals are investigated on the basis of linearized Heffron Phillips model of SMIB equipped with UPFC. The performance of model predictive controller has been compared to that of a controller based on phase compensation technique and is found to be superior as it uses the optimized control inputs to bring stability to the plant.

Most widely used IHS method preserves the spatial information but distorts the spectral information during fusion process. IHS method is also limited to the three bands. In this paper, the MS based difference with respect to its mean image is used to reconstruct the fused image. In this the mean of the MS band is replaced by the mean of the PAN image. In this way both spatial and spectral information are taken into account in the process of image fusion. We have considered actual dataset of IKONOS four band image for our experiment. It has been observed from the simulation results that the proposed algorithm preserves both spatial and spectral information better than compared standard algorithm and it also significantly improves the universal quality index which measures the visual quality of fused image.","PeriodicalId":206392,"journal":{"name":"2011 Nirma University International Conference on Engineering","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121651576","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 the first design, patches of the FSS are designed with 0° rotations to one another while in the second design; adjacent patches are at 90° rotations to one another. In the latter design due to symmetrical nature of the design; the FSS becomes totally polarization independent for 90° rotations about any vertical axis, perpendicular to the FSS plane and passing through its centre and the design also reveals reduced patch size of the FSS with multiband characteristics. The proposed designs have been investigated theoretically using ANSOFT® software. In comparison to the conventional square patch Frequency Selective Surface (FSS) without slot, this slotted square patch FSS with second design can provide reduction in resonant frequency resulting in size reduction up to 94%. The second structure acts like a band reject filter with three bands having resonant frequencies of 5.93 GHz, 9.25 GHz and 13.8 GHz.","PeriodicalId":206392,"journal":{"name":"2011 Nirma University International Conference on Engineering","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127611277","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}
