Paper Title:

Effect of the Error of the Rotor Inductance on the Performance of the Induction Motor with Direct Torque Control Compared to Scalar Control

Abstract: Direct torque control of induction motors has achieved a quick torque response.  It is very sensitive to flux estimation (magnitude and orientation). The flux estimation is affected by parameters variation. These parameters are affecting saturation, temperature, and skin effect. The mismatching between the parameters value used in the controller and those in the motor make the actual rotor flux position does not coincide with the position assumed by the controller. Any parameter mismatched in flux estimation will be detrimentally affect the torque response and then on the dynamic performance. So this paper shows the effect of mismatching in rotor reactance between the control model and the machine itself on the performance characteristics of induction motor through applying the direct torque control. The rotor reactance is chosen due to have more effect on the instantaneous slip speed. To show this effect, the mismatching case is compared to matching case and with scalar control. MATLAB program is used to simulate these cases.

Keywords:  Direct torque control, Induction motor, Rotor reactance error, Scalar controls.

Paper Title:

Investigation of Performance Metrics in OMNET++ for Vehicular Networks

Abstract:  Road congestion, parking difficulty, and collision is very prominent in advanced and developing countries. Intelligent Transport Systems (ITS), with wireless technique has solution to these problems through the application of vehicular technology. The wireless deployment, safety and non-safety applications in vehicular communications can be achieved with proper implementation of network metrics. It is very clear and of no doubt that more research in wireless applications for vehicular networks is on the increase due its application in this modern era. Dedicated Short Range Communication (DSRC) has paved way for these applications in informatics, parking/congestion control, and safety application via the knowledge of the ITS. In this paper, we have made investigations on some performance metrics that have impact in the analysis of vehicular communications. We will use these metrics in our future work, to analysis the performance of vehicle networks with other rate algorithms using OMNET++ as implemented here.

Paper Title:

FARFE: Face Recognition Feature Extraction Approach

Abstract:  In the modern era of computing, object recognition form a deeply entrenched and omnipresent component of intelligent social systems. With data and information accumulating in abundance, there is a crucial need for high security. Biometrics has now received more attention. Face biometrics, useful for a person’s authentication is a simple and non-intrusive method that recognizes face in complex multidimensional visual model and develops a computational model for it. In this work we presented a novel Face Recognition feature selection system, FARFE, based on combination of Particle Swarm Optimization (PSO) and Oriented FAST Rotated Brief (ORB).  The proposed PSO and ORB based feature selection system is utilized to search the feature space for the optimal feature subset where features are carefully selected according to a well-defined discrimination criterion. The classifier performance and the length of selected feature vector are considered for performance evaluation using MATLAB in ORL face database.

Paper Title:

Analysis of Solid Contaminants in Grease Lubricated Deep Groove Ball Bearing through Vibration, Shock Pulse and Temperature Measurement

Abstract: In rotating machinery, automobiles and aerospace, rolling element ball bearing are in common. For frictionless and continuous running bearing is lubricated with grease and oil, Grease are contaminated with various solid and liquid particles. This is one of the major reasons for bearing failures. When Ball bearing gets operated in contaminated conditions, particles of dirt may enter the bearing, the generated vibration and vibration level being dependent on the amount, the size and the composition of the entering contaminant particles. Some manufacturers state that in this case, no typical frequency pattern is generated, although an audible and disturbing noise may be created. Solid contamination is an important question related to the monitoring of rolling bearing performance because of its action on fatigue failure acceleration resulting from surface denting. In this respect, this project work deals with the effect of contamination of lubricant by solid particles on the dynamic behavior of rolling bearings. Generally different materials such as Silica, metal-burr, dolomite-powder, and iron-ore, all at three concentration levels and different particle sizes were used to contaminate the lubricant. Here metal-burr is used as a contaminant. Experimental tests have been performed on the 6207 deep groove ball bearings lubricated with grease, here we analyze and study the effect of solid contaminants in lubrication through vibration, shock pulse and temperature measurement. The trends in the amount of vibration affected by the contamination of the grease were determined. The contaminant concentration as well as the particle size is varied for each test. Vibration signatures were analyzed with respect to root mean square (RMS) values of amplitude in terms of velocity, shock pulse in terms of pulse per seconds, temperature in terms of °C and what is the effect of contaminants on the performance of ball bearing, determined.

Keywords: 6207 deep groove ball bearings, solid contamination, greases, vibration, shock pulse and temperature.
