In a multi script environment, majority of the documents may contain text information printed in more than one script/language. For automatic processing of such documents through Optical Character Recognition (OCR), it is necessary to identify different script regions of the document. In this paper, it is proposed to develop a model to identify the script type of a trilingual document printed in Kannada, Hindi and English scripts. The distinct characteristic features of Kannada, Hindi and English scripts are thoroughly studied from the nature of the top and bottom profiles. The proposed model is trained to learn thoroughly the distinct features of each script. Experimentation conducted involved 1500 text lines for learning and 1500 text lines for testing. The k-nearest neighbor classifier is used to classify the test sample. The results are encouraging and prove the efficacy of the proposed model. The average success rate is found to be 99.5% for data set constructed from scanned document images. © Technomathematics Research Foundation. Source

The contents of this paper reports an experimental investigation carried out to detect the air gap eccentricity faults under varying load conditions using non-invasive transducers to monitor the current and vibration signals as a diagnostic medium. Experimental results of vibration signature analysis using Micro-Electro-Mechanical Systems (MEMS) accelerometer and Motor Current Signature Analysis (MCSA) using Hall Effect current transducers are compared and found nearly common signatures. Spectral analysis is carried out using decimation in time Fast Fourier Transform algorithm using FFT analyzer. This study also examines the usefulness of vibration signature analysis using MEMS to detect the eccentricity faults in developing a compact, miniaturized and cost effective instrument. © 2011 Published by Elsevier Ltd.

Problem statement: Gaze estimation systems compute the direction of eye gaze based on observed eye movements. The need for gaze-contingent applications is the basis of the current research work. The gaze pointing systems is a substitute for the existing input devices. Approach: The gaze tracking methods are either feature based or appearance based. In this study, an appearance based approach for gaze tracking is proposed based on Run Length Coding (RLC). The experiment was conducted considering transitional changes and the class-intervals in iris pixels. The image acquisition begins from the center of the screen in anticlockwise direction. The center of the screen was the pivot point. Results: Using RLC, the recognition rate of 95% was achieved. The image analysis in different directions determines the gaze point. The directions was determined with respect to the pivot point. Conclusion: The proposed system provides a robust, less computational gaze tracking method using web camera. © 2011 Science Publications. Source

In this paper, a study is carried out to determine the magnitude and nature of the induced currents in the steel structure of a steel reinforced concrete building due to a nearby lightning strike to ground. The influence of various parameters of steel geometry of a building on the induced currents is investigated. Electromagnetic model is employed for the study and numerical electromagnetic code 2 is used for the numerical field computations. The time-domain quantities are obtained using appropriate Fourier and inverse Fourier transform techniques in MATLAB. It is observed that the height of the building and increased number of rods in the columns and beams have an effect to increase the peak value of the induced currents. It is also observed that the roof in the building has the shielding effect to reduce the peak value of the induced current. The diameters of the rods and material used have no significant influence on the magnitude and nature of the induced currents. © 2015 IEEE. Source

In this paper, the natural convection in a non-Darcy porous medium is studied using a temperature-concentration-dependent density relation. The effect of the two parameters responsible for the nonlinear convection is analyzed for different values of the inertial parameter, dispersion parameters, Rayleigh number, Lewis number, Soret number, and Dufour number. In the aiding buoyancy, the tangential velocity increases steeply with an increase in the nonlinear temperature parameter and the nonlinear concentration parameter when the inertial effect is zero. However, when the inertial effect is non-zero, the effect of the nonlinear temperature parameter and the nonlinear concentration parameter on the tangential velocity is marginal. The concentration distribution varies appreciably and spreads in different ranges for different values of the double dispersion parameters, the inertial effect parameter, and also for the parameters which control the nonlinear temperature and the nonlinear concentration. Heat and mass transfer varies extensively with an increase in the nonlinear temperature parameter and the nonlinear concentration parameter depending on Dacry and non-Darcy porous media. The variation in heat and mass transfer when all the effects, i.e., the inertial effect, double dispersion effects, and Soret and Dufour effects, are simultaneously zero and non-zero. The combined effects of the nonlinear temperature parameter, the nonlinear concentration parameter and buoyancy are analyzed. The effect of the nonlinear temperature parameter and the nonlinear concentration parameter and also the cross diffusion effects on heat and mass transfer are observed to be more in Darcy porous media compared with those in non-Darcy porous media. In the opposing buoyancy, the effect of the temperature parameter is to increase the heat and mass transfer rate, whereas that of the concentration parameter is to decrease. © Shanghai University and Springer-Verlag Berlin Heidelberg 2010.
