diesel fuel has a limited resource and concerns over environmental pollution areleading to the use of ‘bio-origin fuels’ as they are renewable and environmentally benign. jatrophamethyl ester, an esterified biofuel, has an excellent cetane number and a reasonable calorific value.it closely resembles the behaviour of diesel. however, being a fuel of different origin, the standarddesign limits of...

Due to the growing demand for higher bandwidth, employing optical devices instead of electronic devices in data transmission systems has attracted much attention in recent years. Optical switches, modulators and wavelength converters are a few examples of the required optical devices. CMOS compatible fabrication of these devices, leads to much more growing of this technology. Optical pulse comp...

-------------------------------------------------------------------ABSTRACT------------------------------------------------------------This paper focuses on improving the Image compression ratio and having 100% quality factor. The major emphasis has been on Arithmetic Coding, its principle has been applied to get the wanted results i.e. higher compression ratio than JPEG on an average quality f...

Microarray technology is a new and powerful tool for concurrent monitoring of large number of genes expressions. Each microarray experiment produces hundreds of images. Each digital image requires a large storage space. Hence, real-time processing of these images and transmission of them necessitates efficient and custom-made lossless compression schemes. In this paper, we offer a new archi...
