Lung Cancer Detection Using CT Scan Image

Abstract: Lung cancer is the most perilous and widely spread cancer in the world according to stage of discovery of the cancer cells in the lungs. The motivation of this paper is to discover the cancer cells in the lungs at earlier stage. The lung cancer is detected using CAD System which is an interdisciplinary approach based on the techniques of Image Processing and Machine Learning. The forecasting of lung cancer is the most challenging problem, because of the structure of cancer cells, where most of the cells are superimposed. Recently, the image processing techniques are widely used in several medical areas for detection and treatment levels. The time factor is most important to determine the abnormality issues in the targeted image. Image quality and accuracy are the significant factors for quick identification of diseases. Image quality assessment and advancement are depending on the enhancement stage. By using the Image processing techniques like Image enhancement, image segmentation, Feature extraction we can easily identify the tumours in the image. The formulation of a Computer Aided Detection (CAD) system for Lung cancer detection by using an integrative approach based on the techniques of Image Processing and Machine Learning. The lung cancer detection is the extension of the image processing that produces the results of feature extraction and feature selection after segmentation. The system accepts Lung CT (Computed Tomography) images as input. The proposed method is used to detect the cancerous cells effectively from the CT scan images.

Achieving More Page Views Through Search Engine Optimization

Abstract: A user who wants to search for any data online uses a search engine which displays a list of relevant websites based on their ranking in the search engine result pages. In general, the user will go through only the sites which are displayed in the top positions of the results page. So, the owners of the websites should see that their site is listed in the initial positions to get more views. Especially a commercial or business website should get more viewers to their website compared to that of their competitors. Search engine optimization is an art of designing a website by using different techniques to get a good ranking by the search engine. This paper proposes some new SEO techniques. The experimentation is done with Google search engine, and the results proved that the new techniques, if followed along with the existing techniques, can result more traffic to a website.

Design And Simulation Of Hybrid AC/DC Micro Grid System

Abstract: The proposed system to performance of hybrid AC/DC micro-grid system is analyzed in the grid tied mode. In this, the proposed main converters of DFIG parameters are designed using the mathematical expression and verified with the conventional system. The control blocks are associated with the d-q axis and MPPT algorithms to coordinate the AC/DC micro grid. The Proposed system is designed and simulated using the Simulation software.

Voltage quality detection of micro turbine generating units using wavelet analysis

Abstract: Generating units are distributed throughout the power system closer to the loads in a distribution system. The normal distribution system delivers electric energy to a large number of loads from a single source of power. There will be several sources in a DG system. Hence many power quality issues may arise. In this paper micro turbine generating unit is considered as distributed generating unit. Due to high speed of micro turbine, the output frequency of the generator is also high. Hence this frequency is to be reduced to match with the grid frequency. This is done using a conventional converter normally. A matrix converter is proposed for the same purpose. Here it is shown that a matrix converter is better than conventional converter. Also THD analysis of output voltage of DG system with matrix converter at different load conditions is carried out with FFT and wavelet packet transform using MATLAB/SIMULINK.
