ABSTRACT Diesel engine exhaust gas emissions and particulate matters have been a serious environmental problem for a long time. Many research have been made in order to reduce these emissions since the usage of diesel engines came into large. Major emissions from the diesel exhaust are NOx, SOx, CO and Particulate Matters. Amongst these SOx, CO and Particulate matters can be reduced by using after treatment methods like Catalytic Reduction, etc. Unlike these NOx reduction is a challenging issue

Astonishing Strength Characteristics of Stone-Thrower-Wales Defects in Graphene under Compressive Load G. Rajasekaran Rajesh Kumar and Avinash Parashar Department of Mechanical and Industrial Engineering Indian Institute of Technology, Roorkee - 247667, India ABSTRACT: One atom-thick sheet of carbon discovered this century is flaunted not just for its electrical properties but also for its physical strength and flexibility. The bonds between carbon atoms are well known as the strongest in nature

Cylinder : One Bore : 50 mm Stroke : 50 mm Piston displacement : 98.2 cc Compression Ratio : 6.7:1 Maximum HP : 7.8 HP Reasons for selecting the engine: The above engine is one of the extensively used engines for commercial purpose in India. This engine can with stand the peak pressures encountered because of its compression ratio .Further, the necessary modifications on the piston crown can be easily carried out in this type of engine. Hence

BASED IMAGE COMPRESSION USING DCT AND DWT TECHNIQUE Abstract: Discrete Wavelet Transform (DWT) and Discrete Cosine Transform (DCT) are the most known methods used in digital image compression. Wavelet transform has better efficiency compared to Fourier transform because it describe any type of signals both in time and frequency domain simultaneously. In this paper, we will discuss the use of Discrete Cosine Transform (DCT) and Discrete wavelet transformation (DWT) based Image compression Algorithmand

digital watermarking plays a vital role in providing the appropriate solution and various researches have been carried out. In this paper, an extensive review of the literature related to the color image watermarking is presented together with compression by utilizing an assortment of techniques. The proposed method should provide better security while transferring the data or messages from one end to the other end. The main objective of the paper is to hide the message or a secret data into an

Although database forensic lie in its generalization which should be applicable for all types of operations, B+tree does not give much information about this is the disadvantage described in the paper. The paper “StegFS: Steganographic file system” [1] introduce StegFS, a practical scheme to implement a steganographic file system. StegFS hides user-selected files in a file system so that, without the knowledge of related access keys, an attacker would not be able to find out their existence. Even

Mp3 argument The Next Revolution in Music Technology: Make or Break?      Throughout life I have encountered several different mediums of music including eight-track recordings, vinyl records, cassette tapes, mini-discs, digital audio tapes (DAT), and compact discs. I have always considered the CD to be the greatest technological advancement (as a medium of music) of my generation because it was the first digital audio format made readily available to the general public

cycles. The 2-stroke reciprocating engine completes a power cycle in only one crankshaft revolution and two strokes, compression and power stroke. This is achieved when power and compression stroke happens simultaneously while the piston is near the bottom of its travel. The 4-stroke reciprocating engine operates on the 4-stroke 5-event cycle, which are the intake, compression, power, exhaust stroke and ignition event. During the intake stroke, the piston descends from top dead center (TDC) with

1. INTRODUCTION COMPRESSION • What is compression? Data compression is the method of reducing the number of bits to store or transmit the data. It reduces the size of data to save storage space or speed transmission. Cost is aldo decreased for storage and network bandwidth. Compression is performed by a program that uses an algorithm on how to shrink the size of the data. For data transmission, compression can be performed on the data content or on the entire transmission unit.. When information

What bit rate, in kb/s, is required in the channel from S to A (to the nearest thousandth)? S2.L1.HW 08.2.3 : What type of channel does this service require? S2.L1.HW 08.3 : A geostationary television satellite is located approximately 36000 km above the earth. It relays images from a transmitter on the ground to receivers (television sets) on the ground. S2.L1.HW 08.3.1 : What is the delivery time for these images in this communication channel (to the nearest hundredth of a second)
