Natural aggregates were replaced with recycled aggregates during casting at 0, 25, 50, 75 & 100 percentages using water cement ratio of 0.60.The natural aggregates used were quarried granites from parent igneous rock with maximum sizes of 19mm. While the recycled aggregates were gotten from demolished old concrete building, crushed manually and sieved to also get maximum sizes of 19mm.Total of 75 concrete cubes of 150mm x 150mm sizes were cast and properly cured for 28 days. The concrete cubes were then subjected to different level of temperatures (50°c, 100°c, 200°c, 300°c, and 400°c) for a period of eight (8) hours in the electronic oven. Test results showed an average of38% reduction in strength for all percentage replacements with recycled aggregates within temperature ranges not above 200°c compare to about 25% reduction in strength of samples with 100% natural aggregates. For temperature ranges between 300°c and 400°c, an average of 55% reduction in strength was observed for samples with various percentage replacements with recycled aggregates.<#LINE#>Oikonomou N.D.

There is a chance of modifying in medical images intentionally or accidently if transmitted through open network. The medical practitioner has to verify region of interest (ROI), the diagnosis area of the received medical images before rendering any decision report. In this paper, a medical image watermarking scheme using DCT domain is discussed. The decision area (ROI) is to be separated using Fuzzy c- means and embed watermark in region of non- interest (RONI) using M-ary modulation. The effectiveness of the system is experimentally proved for different MRI medical images using different quality measures as PSNR, MSE, NRMSE, MAE and NCC and revealed that the proposed scheme produced a preferable quality of watermarked medical images.<#LINE#>Anand D. and Niranjan U.C.

The objective of the present work was to investigate the effect low frequency vibration given to workpiece which taken as an input factor with other parameters of WEDM on the cutting speed and surface roughness of machining process. This happened with the help of fixture and vibration actuator. By the help of this vibration unit vibration produced to the workpiece, this vibration removed the debris fast and our cutting speed increased. And with increasing speed the surface roughness minimized. The working ranges and levels of the WEDM process parameters are found from literature survey to investigate the effects of wire WEDM we use Taguchi Method.<#LINE#>Garn R., Schubert A. and Zeidler H.
