that rise in bush temperature is considerable and comparable. Therefore, it should be taken into consideration while
designing offset-halves journal bearing.
Keywords: Offset-halves bearing bush temperature, and Parabolic Temperature Profile Approximation.

This paper presents an experimental study on localization and navigation control based on vision system. The system is
designed for a robot navigating in an indoor environment with a single web camera. A colour image segmentation method
based on RGB (Red, Green, and Blue) colour information of the colour image is applied for the recognition of position and
orientation of a small mobile robot. First, the lower and higher threshold values of RGB are determined for the sample
colours. The colour image segmentation and processing is performed using MATLAB tool. The localization and navigation
control of the robots are efficiently and accurately established by knowing the intensity of each extracted colour region.
Experimental results of the colour image segmentation or threshold segmentation method applied to the recognition of an
object are studied. This work proposes the navigation control of a mobile robot with inexpensive hardware

In present paper effectiveness of fuzzy controller in semi-active quarter car suspension system having magneto-rheological
(MR) damper is studied. For experimental work, cyclic excitation is applied to an MR damper prototype using MTS
machine to generate Force- Displacement and Force-Velocity curves. A fuzzy controller is designed, working on the
feedback data, based on measurable sprung mass velocity and suspension velocity. Finally, a quarter vehicle semi-active
suspension model having MR damper is considered for comparative analysis of simulation work under various road
excitations to evaluate the performance of semi-active suspension system with fuzzy controller compared to passive
suspension system.
Keywords: Quarter car model, semi-active suspension, MR Damper, Fuzzy logic controller

Improving the Impeller life is one of the most significant steps in improving the sustainability of the Flexible Impeller
Pump. For the same purpose it is necessary to know the stress distribution on the impeller vane at specific conditions when
failure is most likely to occur. Also it is necessary to identify the specific locations of failure on the vane. This process is
difficult to carry out by hand calculation or by experimentation due the hyperelastic nature of the impeller material and also
due to the high running speed of the pump.
