The main objective of this paper is to obtain Peak side lobe level (PSLL), equal to or less than - 25dB for uniformly excited antenna elements across the aperture. A Modified Binary Coded GA (MBC-GA) is utilized to find out optimum combination 'ON' and 'OFF' elements by randomly turning on and turning off elements in certain position to obtain the maximum peak side lobe level (PSLL). A novel Crossover and mutation techniques are devised and incorporated in normal BCGA to develop the MBC-GA. In order to validate the effectiveness of proposed method, a 12x12 TPA is considered in present study. Their computed performance is compared with the already proposed literature containing designs of similar size arrays. Comparison shows the superiority of our technique and also indicates acknowledgeable improvements in reduction of peak side lobe levels at bore sight.","PeriodicalId":443423,"journal":{"name":"2017 International Conference on Circuits, Controls, and Communications (CCUBE)","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134159009","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 proposed humidity sensor works on the principle of change in dielectric constant of the polyimide that occurs because of absorption/desorption of water vapor. It is observed that humidity sensor's output depends linearly on the relative humidity in the range of 20 to 90%. The sensitivity of the sensor shows that the range is 0.13 for 0.04fF per %RH to 1.36 for 4 fF per %RH. Modeling and simulation is carried out with parameters of different input values of pressures in accordance with minimum distances between micro plates array, the number of plates and the width of the plates for analysis. As the model is used to observe the water diffusivity in the polymer, polyimide layer is based on Fick's law and Henry's law. And hence could be extended for the parametric optimization of capacitive sensors in terms of stress, displacement and surface analysis. A Humidity sensor that works on capacitive principle is implemented in this paper. Sensor consists of array of plates onto the sensitive polyimide layer. The polyimide layer is sandwiched between the top electrode array and the bottom oxide layer.","PeriodicalId":443423,"journal":{"name":"2017 International Conference on Circuits, Controls, and Communications (CCUBE)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114754938","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}

For the detection of lung cancer, pulmonary CT (computed tomography) image processing is required. Discrimination of vessels from other organs in the lung is required for the detection of lung nodules. This is an important step in the diagnosis of lung cancer since the size and shape of the nodules indicate the severity of lung cancer in the patient. Therefore, vessel segmentation has received a large amount of interest, and a variety of techniques have been proposed for this task. Vessel detection techniques have been widely used in brain MRI images and retinal images, and have been shown to apply to segmentation of lung vessels as well. Radon transform is a technique which transforms line-containing images to a radon transform domain where every line is represented as a peak or a valley. This helps to understand the intensity and position of the lines in the image. This technique has shown success in the segmentation of blood vessels in retinal images, and in this paper, we use it for the segmentation of lung vessels. Pre-processed lung CT images are partitioned and further processed. The Radon transform is then applied. Vessel mask parameters are defined and analyzed to obtain a final vessel map highlighting the blood vessels in the source lung CT image.","PeriodicalId":443423,"journal":{"name":"2017 International Conference on Circuits, Controls, and Communications (CCUBE)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132570741","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}

This algorithm is used to overcome the limitation of imaging CMOS sensors. It is difficult to obtain a HR image by reducing the size of the sensor after a certain limit. SR technique is used in many visual applications like biological imaging, military applications and forensic investigations. It is basically an inexpensive process to enhance the resolution of an image and to extract the high-frequency information. Two different adaptive schemes are proposed here. First one focuses on minimizing the error between the actual image and the estimated image. Resolution enhancement is done here by simultaneously modeling a blurring filter to capture the degradation process as well as modeling an innovation filter to remove the blurring effects, sensor noise using adaptive Least Square technique. The second scheme incorporates the advantages of both visual quality improvement as well as the increase in PSNR by jointly using wavelet transforms and adaptive normalized Least Mean Square (NLMS) technique. Results and performances of these novel techniques are compared with other available Super Resolution methods in terms of the visual quality index like PSNR, SSIM. Numerical results indicate that these computationally efficient single image super resolution techniques are very effective in real life imaging applications as a significant improvement of visual quality is observed in the super resolved image.","PeriodicalId":443423,"journal":{"name":"2017 International Conference on Circuits, Controls, and Communications (CCUBE)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115095086","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}
