Object Based Image Analysis of High Resolution Satellite Image using Radial Basis Function Neural Network and Curvelet Transform
ABSTRACT Image-object extraction is one of the most important parts in the image processing Object-based image analysis (OBIA) method classify individual pixels directly, This method first aggregates image pixels into spectrally homogenous image objects by using an image segmentation algorithm and then classifies the individual objects using any classifier. Image segmentation is one of the […]
Effect of Frame variation on Nakagami and Rayleigh Channel through M-FSK Modulation Technique
ABSTRACT The main objective of this research work is to analyze the effect on SNR over BER in Different Fading channel using various digital modulation techniques (i.e. BPSK and BFSK) using Single Frame and Multi Frame data transmission techniques. Nakagami fading channel gives better analysis of results as compared to Rayleigh and Rician fading Channels. […]
A Survey on Face Recognition Techniques in Video
ABSTRACT With facts and figures accumulating in riches, there is a severe extremity for high safety. Biometrics has now embraced more study. Face recognition grant an insubordinate question in the extent of image analysis and electronic computer vision. The security of information is comely very momentous and difficult. Face recognition is necessity in security. In […]
Parameter Estimation in Surface Radiation Heat Transfer using Least Square Residual Method and Bayesian Approach in Vertical Plate
ABSTRACT Emissivity is a parameter which helps to determine emissive power of a Surface. Much experimental work in radiation has been done to find out the value of emissivity for different surfaces. The paper reports the ability of Bayesian Approach and least square method in parameter estimation when radiation heat transfer is encountered. The aim […]
Estimation of Heat Dissipation from Plate with Multiple Tapered and Rectangular Fins
ABSTRACT The current work determines the rate of heat flow from a heating element. Extended tapered surfaces are provided on the element in order to enhance better convection. Overall heat transfer during this process is determined by modeling and meshing using finite element software and its validation is done using the governing equations. The heat […]
Simulation of High Efficiency Grid Connected THIPWM-Three Phase PV Inverter
ABSTRACT This paper presents a three phase DC-AC inverter for grid connected PV system using Third harmonic injection PWM (THIPWM) technique. The SPWM technique is easiest modulation scheme to understand but it requires complicated mathematical operation so third harmonic injection techniques for PWM (THIPWM) is employed to reduce the total harmonic distortion (THD) and to […]
Luitspell: Development of an Assamese Language Spell Checker for Open Office Writer
ABSTRACT This work primarily aim on different aspects of designing a spell checker for the Assamese language and integrating it as an add-on into Open Office Writer. Besides emphasizing on error detection and suggestion generation the programming model and challenges of developing the add-on for the aforementioned application has also been discussed. The system also […]
HHO Generator – An Approach to Increase Fuel Efficiency in Spark Ignition Engines
ABSTRACT This paper is all about designing an efficient Hydrogen-Hydrogen-Oxygen (HHO) generator, that produces Hydroxy gas which can be used to increase the fuel efficiency in an internal combustion engine. In a combustion engine, high pressure products of combustion expand through a turbine or a piston in order to generate power. In this scenario the […]
Preparation of Porous Polyacrylonitrile/Poly (vinylidene fluoride) Nanofibers via Selective Dissolution of Electrospun PAN/PVdF/PMMA Nanofibers
ABSTRACT In order to prepare porous PAN/PVdF nanofibers, PAN/PVdF/PMMA blend nanofibers were electrospun and then the PMMA was removed via a selective dissolution technique with chloroform. After extraction of the PMMA, the resulting PAN/PVdF nanofibers had highly porous surface. The surface morphology was characterized using scanning electron microscopy (SEM). The Brunauer-Emmett-Teller (BET) surface area of […]
