ABSTRACT
This project is based on suspension system of an automobile vehicle. This report gives information about electromagnetic suspension system. The aim of this project is to study and investigate the response of system, when it is subjected to road surface irregularities with the hope that it would help automobile industry. This project presents design, construction and working of one wheel vehicle electromagnetic suspension system. This system uses electromagnets as passive dampers, which is used to reduce displacement and acceleration of sprung mass in order to improve ride comfort. Main performance parameter of suspension system is vertical acceleration of chassis.

ABSTRACT
The present study was undertaken to investigate the use of waste orange peel as an adsorbent for adsorption of Cu (II) from aqueous solution after effectively extraction of value added component pectin. Four parameters affecting adsorption were studied, are pH (2.6, 4.3, 5.2, 6.8, 7.6), contact time (20, 40, 60, 80, 100 min), initial concentration (100, 200, 400, 600, 800, 1000 ppm) and adsorbent dosage (0.1, 0.2, 0.4, 0.6, 0.8, 1.0 gm.). The optimized parameters for maximum adsorption capacity was found to be concentration of 100 ppm at pH 6 to 7, contact time 60 to 100 min and adsorbent dosage of 1 gm. for 20 ml copper solution for both adsorbents. Maximum % removal of Cu (II) for pectin extracted orange peel was found 80.95% while for fresh orange peel it is 87.30%. The kinetics study was done by fitting the equilibrium data to Langmuir, Freundlich and Tempkin adsorption isotherm. It was found that Langmuir isotherm fitted well and most appropriate to describe adsorption kinetics. The adsorption of Cu (II) for both adsorbents follows pseudo second order kinetics and rate of adsorption is controlled by film diffusion.

JERS/ Volume V/ Issue II/April-June.'2014/10-13

ABSTRACT
Here we have shown the schematic in detail for implementing a high speed chaotic optical communication system with the external optical feedback path length as its dynamic key for digital data transmission. This dynamic key is message dependent and hence time varying also. This makes the system more secure and reliable compared to other existing encryption systems.

OPTIMIZATION OF CUTTING PARAMETERS OF END MILLING ON VMC USING TAGUCHI METHOD

Authors: *N .V. Malvade, S. R. Nipanikar

JERS/ Volume V/ Issue II/April-June.'2014/14-17

ABSTRACT
In this paper, the milling of OHNS steel material using End milling with a high speed steel tool material by using Taguchi methodology has been reported. The Taguchi method is used to formulate the experimental layout, to analyse the effect of each parameter on the machining characteristics, and to predict the optimal choice for each end milling parameter such as Speed, Feed, Depth of cut. It is found that these parameters have a significant influence on machining characteristic such as material removal rate (MRR), surface roughness ( Ra, Rq and Rz), parallelism. The analysis using Taguchi method reveals that, in general the depth of cut significantly affects the MRR and speed significantly affects the surface roughness..
