In this paper, the design and analysis of rectangular Microstrip patch antenna with half hexagonal fractal geometry has been proposed. The proposed antenna operates at multi-resonant frequencies. The dielectric material Roger RT duroid/5880 has been employed as a substrate material for designing the proposed antenna having thickness 2mm with relative permittivity (ɛr) of 2.2 with loss tangent (δ) 0.0009. The Co-axial feed line has been used to fed the power to the antenna with proper impedance matching of 50Ω so maximum power can transfer. The performance of proposed antenna has been analyzed in terms of return loss (dB), gain (dB), directivity (dBi) and VSWR. The proposed antenna design can be used for S band, C band and X band applications such as weather forecasting, military, satellite communication, wireless communication and radar. The High Frequency Structure Simulator (HFSS) v.13.0 has been used for the analysis and simulation of proposed antenna.","PeriodicalId":13972,"journal":{"name":"International Journal of Engineering Research and Applications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80789534","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, the OFDM based WiMAX physical layer makes use of concatenated Reed Solomon Convolutional (RS-CC) code and different modulation techniques with different code rates along with different cyclic prefix. As WiMAX can be used for NLOS (Non Line of Sight) communication so Rayleigh channel has been used as transmission medium. The comparison of various cyclic prefix such as 1/4, 1/8, 1/16 and 1/32 has been done on different modulation techniques over Rayleigh channel. The performance of OFDM based WiMAX physical layer has been analyzed from the graphs between BER (Bit Error rate) vs. SNR (Signal to Noise Ratio) and Spectral Efficiency vs. SNR (Signal to Noise Ratio) for different modulation techniques. The simulation results of BER vs. SNR conclude that different modulations and code rate provide better performance at guard time interval of 1/32.The simulation result of Spectral efficiency vs SNR conclude that 64 QAM with code rate 3⁄4 has highest spectral efficiency because of which it can be used for transmitting larger amount of data with lesser amount of transmission error.","PeriodicalId":13972,"journal":{"name":"International Journal of Engineering Research and Applications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75776518","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 surface Plasmon resonance characteristic of silver nanoparticles was revealed by the UV-Vis spectrum at 400 nm. The crystalline nature of silver nanoparticle was confirmed by X ray diffraction studies. Spherical shaped and monodispersed nanoparticles were found in Scanning electron micrograph. The average size of silver nanoparticles was 41.9 nm as determined by dynamic light scattering. The peak in silver region confirming the presence of elemental silver was determined by Energy dispersive X-ray spectroscopy analysis. Antibacterial activity of silver nanoparticles utilized in this study was found to be more significant than standard Taxim antibiotic against multidrug resistant bacteria such as Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Klebsiella pneumonia.

Edge detection refers to the process of identifying and locating sharp by applying smooth and noisy clinical technic in an image. It has favorable applications in the fields such as machine vision, pattern recognition, object recognition, motion analysis, pattern recognition, medical image processing & biomedical imaging. Segmentation refers to the process of partitioning a digital image into the multiple segments using set of pixels as to simplify and change the representation of an image and easier to analyze. Edge detection highlights high frequency components in the image. Edge detection is becomes more arduous when it comes to noisy images. The study focuses on fuzzy concepts based edge detection in smooth and noisy clinical images. Traditional method of edge detection involves convolving the image with an operator (2-D filter) changes in pixel intensity scene which is constructed to be sensitive to large gradients. Edge detectors form a collection of different images and applying local image processing method to locate sharp changes in the intensity function. In this paper, histogram thresholding is proposed in order to help the edge detection and segmentation of image to found robust way regardless of the segmentation approach applying for histogram thresholding algorithm. This paper shows the comparison of edge detection & segmentation techniques under different conditions & variation of intensity pixel value of the selected algorithms.","PeriodicalId":13972,"journal":{"name":"International Journal of Engineering Research and Applications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88466885","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}
