COMMON RAIL DIRECT INJECTION
COMMON RAIL DIRECT INJECTION
INTRODUCTION:
Today we are seeing an increasing number of passenger cars powered with high speed direct injection diesel engine. This is primarily due to clear advantage of the direct injection combustion process in terms of fuel economy and power density compared to indirect injection concept. The increase in the application of this technology to passenger cars, and the implementation of low emission regulation raise the requirement for more flexible and fully electronic controlled high pressure fuel injection equipment. The common rail has been identified by the automatic market as an attractive injection system for future diesel passenger cars. This injection system operates at very high pressure with a flexible electronic control of fuel delivery, injection timing, injection strategy as shown in fig no1. By controlling these parameters, the common rail is capable of achieving a level of performance and driving comfort for diesel cars similar to that of gasoline powered models with significant fuel economy and low exhaust emission.
The common rail has the potential to achieve a very high pressure capability throughout the whole speed range with pilot and post injections respectively for noise reduction and DeNOx catalyst efficiency improvement. The common rail system (figure1), which has been designed for modern passenger cars and other application.
Common rail direct injection used in S320 CDI and S400 CDI, Mercedes-Benz has achieved an ideal compromise between economy, torque, ride comfort and long life. Whereas conventional direct injection diesel engine must repeatedly generate fuel Pressure for each injection in the common rail engine the pressure is built up independently of the injection sequence and remains permanently available in fuel line.
The common rail upstream of the cylinder acts as an accumulator, the fuel to the injector at a contact pressure of up to 1600bar.Here high speed solenoid valve is regulated by the electronic engine management, separately control the injection timing and the amount of fuel injected for each cylinder as a function of the cylinder’s actual need. In other words, pressure generation and fuel injection are independent of each other. This is an important advantage of common rail injection over conventional fuel injection system.

REVIEW OF LASER MICROMACHINING IN CONTRACT MANUFACTURING
REVIEW OF LASER MICROMACHINING IN CONTRACT MANUFACTURING
ABSTRACT:
This paper explores the wide range of laser micromachining applications used in contract manufacturing. Contract manufacturing is used in several key industries such as microelectronics packaging, semiconductor, data storage, medical devices, communications, peripherals, automobiles and aerospace. Material types include plastics, metals, ceramics inorganics and composites. However laser micromachining is just one available technology for micromachining and other methods will be reviewed. Contract manufacturing offers two important glimpses of the future. Firstly prototype work for new applications often begins in contract manufacturing. Secondly, contract manufacturing can be an economic springboard to allow laser systems to be installed in a production environment.

LASER BEAM MACHINING
LASER BEAM MACHINING
ABSTRACT:
Laser beams when used for cutting can be broadly suitable for similar tasks. The technology can be considered for use in fabrication and sheet metal working departments to work alongside, and as a supplement to, existing press equipment.
Press tools (working on the shearing principle) are a very quick and efficient way to produce components from sheet or strip stock in large quantities, they are however time consuming to set up and expensive to tool.
By adding a laser beam machine to a company's plant list they will be in a much better position to be able to quote competitive prices and lead times for on-off and small production runs.
Laser machines have a significant advantage as being able to cut intricate shapes they are also able to weld with great precision.
Laser has a good life expectancy due to the absence of dynamic machining forces and metal-to-metal contact during the cutting process. The machine construction may be substantially lighter because of this, reducing the static loading and also the dynamic loading during positioning.

AIR-BREATHING ENGINES
AIR-BREATHING ENGINES
INTRODUCTION:
Advancement in technology is bound to improve out transportation systems. Very fast transportation systems have made the world very small. We are now in JET-AGE.
Jet propulsion is based on Newton’s second law and third law of motion.
SECOND LAW: The rate of change of momentum in any direction is proportional to the force acting in that direction.
THIRD LAW: For every action, there is equal and opposite reaction.
In a jet engine, reaction principle is used. The fluid, whose velocity is increased, is ejected from the jet engine in the form of high velocity gases, which gives thrust in the opposite direction to the plane.

Industrial Team Behaviour and Management Tools
Industrial Team Behaviour and Management Tools
Abstract:
We as engineering students are rarely entrusted with teamwork.
It's only during the final year project work that we undergo the experience of working in a team. All too often our instructors thrust students into a team situation without realizing that there isn't enough proper understanding of what is needed to achieve a smooth functioning team. But in case of the current industrial scenario and with industry leaders. "Engineering has been Re-engineered into a Team Sport". These firms want people who are comfortable operating in teams and communicating with earth lings who may know nothing about a circuit board design or quantum mechanics.
But why all the fuss about teams?
This is because if properly handled, teams outer form individuals. No person can posses all the knowledge and skills necessary for a successful solution nor can a person working 20 hours/day can complete all the tasks. Some time things may just wok out fine, but at the cost of extra hours of trial and error to find the best way to function as team. This seminar is intended to give you an understanding of the team building process and introduce you to some tools that people have found helpful in getting results through teams.

LASER IMAGING & DATA REDUCTION
LASER IMAGING & DATA REDUCTION
Abstract:
Computer Modeling is an emerging technology that can play a promising role in reducing product development time. Reverse engineering refers to the process of creating engineering design data from existing parts. It creates or clones an existing part by acquiring its surface data using a scanning or measurement device. Recently, laser scanning technology has improved significantly and become a viable option in capturing geometries of `complicated design models. 3D laser scanners have become more accurate and the speed of data acquisition has increased dramatically. However, they generate up to thousands of points per second, and it becomes a major problem to handle the huge amount of point data. It becomes quite important, therefore, to reduce the amount of acquired point data and convert them into formats required by manufacturing processes while maintaining the accuracy.

EXPERIMENTAL ANALYSIS OF HEAT PIPE
EXPERIMENTAL ANALYSIS OF HEAT PIPE
ABSTRACT:
The world today is standing forward for the ways and means of quickly and efficient transfer of heat from one point to another. Richard S. Gaugler first suggested a device for this purpose in 1942. Then G.M.Groover invented it in 1962, which he named as ‘Heat Pipe‘.
A heat pipe acts like a conductor. It is a simple device that can quickly transfer heat from one point to another. The basic heat pipe is a closed container consisting of a capillary wick structure and a small amount of vaporizable fluid. The heat pipe employs an evaporating condensing cycle, which accepts heat from an external source, uses this heat to evaporate the liquid (Latent Heat) and then releases latent heat by reverse transformation (Condensation) at a heat sink region. This process is repeated continuously by a return feed mechanism of the condensed fluid back to the heat zone by means of wick material.
The heat pipe has a single structure, very high effective thermal conductance and heat transfer capacity, and can work in hostile high temperature environments. In this paper, the performance characteristics of heat pipes are investigated and its performance is discussed from the experimental results and graphs.

ENERGY CONSERVATION IN STEAM POWER PLANT
ENERGY CONSERVATION IN STEAM POWER PLANT
INTRODUCTION:
Energy conservation is one of the critical issues facing society today. Our civilization runs on energy. However, energy resources are finite. Increasing demand is being made for diminishing supplies. The cost of energy is enormous, and the cost is rising.
The imperative to conserve energy is as old as the use of energy. For most of human history, use of energy was limited to the amount of work that could be done by human beings, usually alone, but sometimes in large groups. Later, humans learned to use animals and teams of animals to do the tasks requiring heavy lifting and hauling. Neither humans nor animals like hard work. Aversion to work strongly motivated energy conservation from the beginning. Energy conservation first consisted of doing less. Then, as intelligence evolved, it included finding easier ways to get work done. For example, the invention of the wheel was an early advance in energy conservation.
Wind power is the oldest major source of mechanical energy, other than muscle. Its earliest major application was ship propulsion, which began perhaps five to ten thousand years ago.
Land-based rotary wind machines have been used in a limited number of cultures for over two millennia. Efficiency evolved by trial and error.
The energy of falling or flowing water has been used to a significant extent for over two millennia, becoming a major energy source in the Middle Ages. Unlike wind, which is a nuisance in itself, water is desirable for many important purposes. As a result, many cultures settled near water supplies, which they learned to exploit for power. Well designed "overshot" water wheels built 500 years ago have efficiencies that approach the theoretical maximum. Water power is limited by the amount of stream flow and by the height of the fall that is readily available. The technology of building dams tall enough to augment power production was not highly developed until the 19th century.
Steam machinery is another application of fire. It was first put into practical application during the 18th century. Its development was revolutionary for several reasons. It enables fire to produce mechanical work. It was the first invention capable of producing mechanical power in any locale, on land or sea. Virtually any amount of work can be done by building larger machines. Steam engines can operate whenever work is needed, independent of climate. To a large extent, steam power created modern civilization. However, steam machinery requires fuel, unlike wind and water power. The ability of mechanics to build large steam engines, and the growth in applications for such engines, led to rapidly increasing demand for fuel, which could no longer be satisfied by whatever excess wood happened to be in the vicinity. Fuel cost soon emerged as a dominant limitation to the application of steam machinery.

DOOPSTIC EXTRUSION MACHINE
DOOPSTIC EXTRUSION MACHINE
PREFACE:
In earlier times, there were cutting materials like cutting by hand, with tools made from bone, stick or stone. These were adopted during the years over two and half million years ago. The materials can only used for cutting clothes, cooking utensils, shelters and weapons.
Later, elementary materials such as bronze and iron were employed as cutting materials. These were introduced in 17th century, and used only for softer materials.
Later on, progress had been taken on the development or technical advancement on the cutting materials like steel, etc. during 18th century.
Later on machines like lathes, milling machines, etc. were introduced with many of great features. The introduction of such machines in the field made easier to those which could not be performed machining like cutting, drilling, turning, etc. by using the cutting materials used during earlier periods.
Steels having more additional properties like strength, toughness, temperature resistance, etc. were introduced as cutting materials. These materials include carbide steels, high carbon steels, etc.
These became the convenient and conventional methods of machining which are used even at present.
Generally, in conventional methods of machining like drilling, milling, lathe turning, etc. mechanical cutting action that arises when a sharp tool makes contact with the softer material. The machining processes using these principles are laid on the manufacturing process for almost two centuries.
In recent years, however attention has turned towards the application of non-conventional methods of material due to the development of harder materials.
# Beams of electrons and gaseous ions.
# Electrolytic dissolution
# Light in the form of LASER beam
# Spark generated by the breakdown of a liquid dielectric when a voltage is applied between
two electrodes
# Plasma of ionized gas
# Erosive effects of granular particles undergoing ultrasonic vibration.
# High pressure water jet
# High pressure abrasive jet
These are used as the cutting material for their respective machines.

Generally, in conventional methods of machining like drilling, milling, lathe turning, etc. mechanical cutting action that arises when a sharp tool makes contact with the softer material. The machining processes using these principles are laid on the manufacturing process for almost two centuries.
In recent years, however attention has turned towards the application of non-conventional methods of material due to the development of harder materials.
# Beams of electrons and gaseous ions.
# Electrolytic dissolution
# Light in the form of LASER beam
# Spark generated by the breakdown of a liquid dielectric when a voltage is applied between
two electrodes
# Plasma of ionized gas
# Erosive effects of granular particles undergoing ultrasonic vibration.
# High pressure water jet
# High pressure abrasive jet
These are used as the cutting material for their respective machines.

DRY MACHINING
DRY MACHINING
INTRODUCTION:
‘Machining process is a Metal cutting operation by which finished surface of desired shape and dimensions is obtained by separating a layer from the parent work piece by pressing a wedge shape device called cutting tool to the work piece.’
Manufacturers all over the world are trying to discover new methods to eliminate the use of cutting fluids. According to studies carried out in United States of America 15% of the cost of the production is spent in purchase, storage, handling, utilizing and safe disposal of the fluid.
Although most shops might acknowledge the desirability of eliminating their cutting fluids, they are not sure they can. They believe that cutting fluids are necessary to reach the higher speeds and cut the harder materials that they must use to stay competitive. Many also perceive the costs of changing a wet operation to a dry one as high. But this is not true now days. In fact, machining dry should be routine practice in many operations especially in high speed. Moreover, turning hardened materials dry and milling at high speeds dry are not only possible but also profitable. The trick is to integrate the tools, machines, and cutting techniques correctly.

Paper MIT diesel
ABSTRACT:
As we know diesel engines are reliable, fuel efficient, durable, easy to repair, and inexpensive to operate. Also a diesel engine commonly has a life of one million kms in heavy-duty trucks, and can power city buses for 10-12 years. Diesel engines offer better fuel efficiency resulting in lower global-warming emissions.
But recent reports from health experts have identified serious health risks associated with emissions from diesel engines, especially oxides of nitrogen (NOx) and particulate matter (PM) emissions. Cost-effective diesel exhaust control options such as catalysts and particulate filters are available which can significantly reduce emissions from diesel-powered trucks, buses, and off-road equipment.
Various types of oxidation catalysts & oxidizers offer a technological solution to controlling diesel particulate matter and offer an effective control strategy. Oxidation catalyst, Trap oxidizer technology can substantially reduce particulate, smoke and odor from diesel engines. Advances continue in the development of lean-NOx catalysts, oxidation catalyst & trap oxidizer technology and improvements evolve which would further enhance the application of this technology to diesel engines

IMPROVEMENT IN TOOL LIFE OF MILLING CUTTER BY APPLICATION OF CRYOTREATMENT
IMPROVEMENT IN TOOL LIFE OF MILLING CUTTER BY APPLICATION OF CRYOTREATMENT
ABSTRACT:
The term Cryogenic is derived from the Greek word ‘Cryo’ which means ice, cold or frost ‘genics’ means born. Cryogenic deals with production & utilization of low temperature below 0oc. The oxygen was firstly liquified in 1877 by coilletet & pietet in USA. The research work is also start at that time.
Cryogenic is of great importance in our day to day life applications and also is specialized applications.
Space research, it is used as a fuels in rocket, commercial application, Cryobilogy, Cryosurgery, in computers and industries.
Cryogenic treatment is very benifited as computer to conventional heat treatment. In conventional heat treatment austenite is converted into martensite. The conversation percentage of martensite on range of 30% to 50%. The retained austenite forms cracks in metal which reduce tool life. But when we Cryotreat the tool below 0oc using liquid Nitrogen. The austenite completely converted into martensite and martensite is hard so tool life is increased.
Actual Cryogenic treatment on tools can be done by two methods
1. Shallow Cryogenic process
Cooling at –120oc by means of dry ice or ultra cold nitrogen.
2. Deep Cryogenic process
Deep Cryogenic process means cooling at -196oc by liquid nitrogen.
After Cryotreatment mechanical properties are improved like strength, fatigue strength, impact strength, hardness and wear properties and thermal conductivity with tool life and when we perform actual Cryogenic treatment on tool the life of tool increased by 44%.

CRYOPUMP-DESIGN AND APPLICATION
CRYOPUMP-DESIGN AND APPLICATION
ABSRACT:
Cryopumping is associated with vacuum technology involving cryogenic engineering. The term is derived from the Greek word Kryo's, which means cold or frost. Cryogenics is frequently applied to very low temperature refrigeration applications such as the liquefaction of gases and in the study of physical phenomenon at temperatures approaching Absolute Zero. In the field of cryogenic engineering, one is concerned with the developing and improving low-temperature techniques, processes and equipment. Various areas involving cryogenic application are Space Simulation & high vacuum technology, Rocket propulsion systems, studies in high energy physics, Electronics, mechanical design, Biological and Medical applications, food processing, Manufacturing processes, Recycling materials.
In space simulation and high vacuum technology, to produce a vacuum that approaches that of outer space (from 10-12 torr to 10-14 torr) (1 pa =10-2 torr), cryopumping is used. Cryopumping, or freezing out the residual gases is used to provide the ultra high vacuum required in space simulation chambers and in test chambers. For space propulsion system the cold or free space is simulated by cooling a shroud within the environmental chamber by means of liquid nitrogen. Dense gases helium at less than 20K or liquid helium is used to cool the cryopanels that freeze out the residual gases.
Thus the cryopump serves an important means to maintain high vacuum, which is useful in space simulation programs.

Introduction:
Overview of Diesel engine operation-
Diesel engine is (CI) compression ignited engine. It doesn’t use a premixed charge like SI engines. At the end of the compression stroke, liquid fuel is injected in the hot air present in the engine. The fuel injected at high velocity through one or more small orifices and nozzle, atomizes into small drops and penetrates into combustion chamber. The fuel vaporizes and mixes with hot air. Since temperature of air is above the ignition point of fuel spontaneous ignition of fuel-air mixture occurs after a delay period of few crank angle degrees.
Diesel injection: The function of a fuel injection system is to inject proper quantity of fuel into the engine cylinder at the correct time and at a predetermined rate. In case of multi-cylinder engines the injection system takes care of the sequence of injection in addition to the injection timing.
Conventional “Individual pump fuel injection system”: (Refer fig….)
This system uses in-line injection pump. Fuel is drawn from the fuel tank by means of a fuel feed pump which is operated from the injection pump camshaft. The fuel is then passed through a filter and then to the fuel injection pump. The fuel injection pump than, injects definite quantity of fuel into individual cylinders in turn according to firing order, through injectors fitted on them. This system is most commonly found on today’s diesel engine. However with the advent of stringent emission norms the system is bound to get outdated.
Brief Introduction of Common rail accumulator fuel-injection system.
In this system generation of pressure and fuel injection are completely decoupled from each other. The injection pressure is generated independent of injected fuel quantity. The fuel is stored under pressure in the high pressure accumulator ready for injection. The injected fuel quantity is defined by the driver, and the start of injection and injection pressure are calculated by the ECU on the basis of stored maps. The ECU triggers the solenoid valves so that the injector at each engine cylinder injects accordingly. Using the input signals from various sensors the ECU registers the drivers requirements and defines the instantaneous operating performance of the engine and the vehicle as a whole.

CONCURRENT ENGINEERING
Abstract:
Intense competition in the global market for mechanical parts has compelled manufactures to reduce delivery times and quote competitive prices for meeting today’s customers expectation like superior quality, higher capabilities and superior performance.
Concurrent or simultaneous engineering is a methodology of restructuring the product development activity in an organization using a cross functional team and is a technique adopted to improve the efficiency of product design and reduce the product design cycle time.
This methodological approach is applied to all activities from the design of the product to customer support in an integrated way, in order to achieve production improvement, cost reduction, fulfillment of scheduled delivery dates, quality improvement and total flexibility in the manufacturing system.
In this paper simulation of casting process in foundries is presented. Today’s dynamic world requires quick responses to customers need. Thus casting simulation has become an everyday tool for the foundries which covers around 90%of the production of cast machine component. Over 90% of those foundries use cast CAE simulation.

CLUSTER DEVELOPMENT IN NRW AND SCOTLAND
CLUSTER DEVELOPMENT IN NRW AND SCOTLAND
Introduction:
Comparing the approach to clusters in the two regions has not been a straightforward
exercise. The widely differing political structures, population and business densities,
cultural attitudes and general approaches to economic development meant that we
could not compare like with like, as was the initial intention. However, upon realising
this fact, we changed the nature of this study. Rather than examining which approach
is best, we looked for complimentarity and comparison.
In particular, NRW, due to its political structures, must pursue a policy-led approach.
It lacks experience of a single organisationally focussed, pragmatic approach to
strategy and development. Conversely, Scotland has a recognised strength in its

Introduction:
Comparing the approach to clusters in the two regions has not been a straightforward
exercise. The widely differing political structures, population and business densities,
cultural attitudes and general approaches to economic development meant that we
could not compare like with like, as was the initial intention. However, upon realising
this fact, we changed the nature of this study. Rather than examining which approach
is best, we looked for complimentarity and comparison.
In particular, NRW, due to its political structures, must pursue a policy-led approach.
It lacks experience of a single organisationally focussed, pragmatic approach to
strategy and development. Conversely, Scotland has a recognised strength in its
strategic approach to cluster development yet has no policy. Furthermore, Scotland
does not see the need for explicit policy development in this area.
The conclusions and recommendations that follow therefore focus on the areas where
practices from one region will enhance, rather than replace, current practices in the
other.

The Dawn Of The Net
The Dawn Of The Net
BASIC NETWORK CONCEPTS:
Networks are an interconnection of computers. These computers can be linked together using a wide variety of different cabling types, and for a wide variety of different purposes.
The basis reasons why computers are networked are
to share resources (files, printers, modems, fax machines)
to share application software (MS Office)
increase productivity (make it easier to share data amongst users)
Take for example a typical office scenario where a number of users in a small business require access to common information. As long as all user computers are connected via a network, they can share their files, exchange mail, schedule meetings, send faxes and print documents all from any point of the network.
It would not be necessary for users to transfer files via electronic mail or floppy disk, rather, each user could access all the information they require, thus leading to less wasted time and hence greater productivity.
Imagine the benefits of a user being able to directly fax the Word document they are working on, rather than print it out, then feed it into the fax machine, dial the number etc.
Small networks are often called Local Area Networks [LAN]. A LAN is a network allowing easy access to other computers or peripherals. The typical characteristics of a LAN are,
physically limited
high bandwidth
inexpensive cable media (coax or twisted pair)
data and hardware sharing between users
owned by the user

NETWORK SECURITY
NETWORK SECURITY
ABSTRACT:
Threats to information security are appearing more and more frequently, and are of greater magnitude, than ever before. Threats come from both internal and external sources. They can be online or local, and range from accidental to malicious to criminal attacks that can expose your most sensitive business information to unauthorized use, disclosure, modification or even total loss.
Network security is a complicated subject, historically only tackled by well-trained and experienced experts. However, as more and more people become ``wired'', an increasing number of people need to understand the basics of security in a networked world. This paper is written with the basic computer user and information systems manager in mind, explaining the concepts needed to read through the hype in the marketplace and understand risks and how to deal with them.
This paper discusses the importance of security, threats to data, who are the enemies? What these enemies can do, Security tools. We go on to consider risk management, network threats, firewalls, and more special-purpose secure networking devices.

HYBRID BEARINGS
HYBRID BEARINGS
INTRODUCTION:
Hybrid bearing is made up of metal rings and silicon nitride ceramic with lubricant and retainer appropriate to the type of bearing and application. The silicon nitride balls typically allow for higher speeds, lower operating temperatures, extended lubricant life and many other performances. Compared to steel balls, CERAMIC balls are lighter, smoother, stiffer, harder, corrosion resistant and electrically resistant. These fundamental characteristics allow for a wide range of performance enhancements in bearings.(figure:1.0)

DESIGN AND ANALYSIS OF CENTRIFUGAL PUMP USING CFD [COMPUTATIONAL FLUID DYNAMICS]
DESIGN AND ANALYSIS OF CENTRIFUGAL PUMP USING CFD [COMPUTATIONAL FLUID DYNAMICS]
Introduction:
It is said that the first industrial revolution was experienced in 18th century when attempts were made to substitute muscle power by mechanical energy. The world is now passing through 2nd industrial revolution with fantastic advances in computers, electronics and computer substituting human brain.
In today’s date the concept of design and analysis is getting a new look, new definition and meaning. Traditional design methods are being replaced by CAD /CAE system. Traditional methods have some limitations, errors and consume long time. CAD /CAE system are giving new look to the design and analysis procedure.
In today’s fast changing world where many number of products are being launched daily, testing of product for durability and reliability before launching them into market is of key importance for manufacturers.
The method of prototype testing has been now in use for long time. There is high cost involved in making prototype, also if design changes, changes in prototype have to be done which is also time consuming.
It is here that CAD /CAE systems come to our aid. CAD helps to build the prototype or model through CAD softwares. The model is stored in memory of computer. CAD helps in quick design of model with less time, efforts, greater accuracy .it also helps in good visualization and understanding of the model or prototype .now these model can be taken to CAE system for simulation. In simulation the model is subjected to real conditions that the actual prototype will have in real world. The results obtained through this gives us a close look to behavior of model and visualization of model under the real conditions.
The benefit of verifying design with computers is speed, less cost, flexibility and accuracy of design. Also CAE offers better representation of real world conditions and performans, those to which physical model is subjected.
The objective of this project is “Design and Analysis of centrifugal pump using CFD” through which a sincere effort is made to learn and implement the new concept of design and analysis. The aim behind attempting such project is to learn the CAD / CAE systems, design and analysis procedures which are adopted in today’s date in industries.
In this project mechanical design of impeller and casing of centrifugal pump is done. The solid modeling of impeller and casing is done in CATIA-V5R11 software. After this the model is imported in GAMBIT software in which meshing is done. And simulation is performed in FLUENT 6.1 CFD (Computational Fluid Dynamics) package.
The results obtained from simulation are compared with the theoretical values, which are nearly same. The C-program of design is done to get required dimensions and parameters related to centrifugal pump.
Thus the project is conducted successfully with the help of CAD / CAE softwares.

Cellular Access Technologies
Cellular Access Technologies
Introduction:
There are three common technologies used by cell-phone networks for transmitting information:
• Frequency division multiple access (FDMA)
• Time division multiple access (TDMA)
• Code division multiple access (CDMA)
Although these technologies sound very intimidating, you can get a good sense of how they work just by breaking down the title of each one.
The first word tells you what the access method is. The second word, division, lets you know that it splits calls based on that access method.
• FDMA puts each call on a separate frequency.
• TDMA assigns each call a certain portion of time on a designated frequency.
• CDMA gives a unique code to each call and spreads it over the available frequencies.
The last part of each name is multiple access. This simply means that more than one user can utilize each cell.
Code-Division Multiple Access, a digital cellular technology that uses spread-spectrum techniques. Unlike competing systems, such as GSM, that use TDMA, CDMA does not assign a specific frequency to each user. Instead, every channel uses the full available spectrum. Individual conversations are encoded with a pseudo-random digital sequence.
GSM stands for Global System for Mobile communications. The GSM is built around the TDMA, or the Time Division Multiple Access concept.
Basically, the two technologies address differently the same fundamental problem of mobile communication, how to divide the finite frequency of airwaves between multiple users at the same time, or, how to make more than one person to carry on a
conversation on the same frequency without causing mutual interference.
CDMA takes an entirely different approach from TDMA. CDMA, after digitizing data, spreads it out over the entire available bandwidth. Multiple calls are overlaid on each other on the channel, with each assigned a unique sequence code. CDMA is a form of spread spectrum, which simply means that data is sent in small pieces over a number of the discrete frequencies available for use at any time in the specified range.

CAVITATION SHOTLESS PEENING
CAVITATION SHOTLESS PEENING
ABSTRACT:
Cavitation impact, which normally produces severe damage in hydraulic machinery, can be used to modify surfaces in the same way as shot peening. Cavitation impact enables he surface of a material to be peened without the use of shot, thus it is called cavitation shotless peening. As there are no solid body collisions occurring in this peening process, the roughness of the peened surface should be less than that produced by shot peening. This characteristic makes it suitable for peening soft metals. In order to demonstrate the improvement of the fatigue strength of aluminum alloy by this process, specimens were subjected to the process, and then tested in a rotating bending fatigue test. Cavitation impacts were produced and controlled by using a submerged high speed water jet with cavitation, i.e., a cavitating jet. It was revealed that the fatigue strength of an aluminum alloy specimen treated by this peening process was 50% stronger than that of a specimen without peening.

Market Research and Analysis
Market Research and Analysis
Introduction:
What is BPO?
Business Process outsourcing (BPO) can be defined as the transfer of an organization's entire non-core but
critical business process/function to an external vendor who uses IT based service delivery. BPO aims to
raise a Client company’s shareholder value because it is about delivering outcomes—that is, higherperforming
business processes.
Companies essentially have three kinds of processes: core processes (which give strategic advantage),
critical, non-core processes (which are important but are not competitive differentiators), and non-core, noncritical
processes (which are needed to make the environment work). No one suggests outsourcing core
processes; they recommend investing in them. But many do recommend outsourcing critical, non-core
processes to providers who specialize in those processes because they will invest in them and aim to make
them world-class. And most advisors recommend outsourcing all non-core, non-critical processes.
Outsourcing does not mean handing over an entire process. Generally, it means turning over to a BPO
provider the “how” aspects of a process—the systems, infrastructure, administration, execution, and some
of the design of non-core processes. But retain the “what” aspects of the process—the governance, policysetting,
decision making, and strategy of these processes. The intent is to outsource the work (the boring
part) while retaining the direction-setting part.
Outsourcing is not a one-time event; it is continuous. Companies that outsource one process later
outsource another, then another—as their strategies change and new outsourcing options open up. The
outsourcing field is thus not slowing down. At the moment, BPO is the driving force, and it is developing
fast.

BIOMETRICS – AN UPCOMING TECHNOLOGY
BIOMETRICS – AN UPCOMING TECHNOLOGY
INTRODUCTION:
Many organizations struggle with the problem of authentication; how users prove their identity in order to get access to applications or other resources. How strong or how secure does the authentication process need to be? Is the combination of a username and password sufficient? If not, should a token device – like SecurID or digital certificate be required? None of these solutions is without its problems.
In recent years, biometric technology has emerged as a practical alternative that offers a reasonable level of security. This brief paper offers some insight into the key benefits and critical limitations of the technology.
Biometrics, defined broadly, is the scientific discipline of observing and measuring relevant attributes of living individuals or populations to identify active properties or unique characteristics Bank auto-teller machines have improved the security level with the requirement that the customer must also provide something known, such as a PIN number. Keys, transponders and smart-cards can be stolen, and, in some cases, copied. PIN number or other forms of knowledge, such as passwords, can be forgotten or observed and are also inconvenient to remember and use.
Biometrics provides the advantage that access is based on who the user is, and not on what is possessed or known. This implies that the driver himself becomes the key. Convenience is improved, as a key or transponder are no longer required.

DATA MIRRORING
DATA MIRRORING
ABSTRACT:
There are various techniques that are used for achieving data recovery by the means of data redundancy. The RAID (Redundant Array of Independent Disks) devices use various data mirroring techniques. The chief advantage of mirroring is that it provides not only complete redundancy of data, but also reasonably fast recovery from a disk failure.
In this document we are going cover the basic idea behind the mirroring techniques.
The mirroring is actually creating another copy of data which can be retrieved immediately after the data loss.
The mirroring techniques help to improve the read performance considerably. The techniques like Network data mirroring, Asynchronous data mirroring and also Remote data mirroring are considered for the discussion in following sessions.

Zero Configuration Networking
Zero Configuration Networking
Introduction:
The evolution of the IP standards suite has concentrated on achieving a reliable and scalable networking architecture. Emphasis has always been placed on mechanisms that allow decentralized administration. Individual networks have been operated with local configuration, while Internetwide configuration has been coordinated through different agencies handling registration of domain names, network numbers, and other parameters.
Network operation requires consistent configuration of all hosts and servers and normally requires centralized, knowledgeable network administration and increasingly complex configuration management services.
It is important to note that there are other networking protocol suites with different priorities and deployment characteristics. In particular the AppleTalk Protocol Suite is simple to operate in small networks, though it requires system administration in larger deployments. Automatic configuration and ease of deployment were of primary importance to AppleTalk's designers. As a consequence, AppleTalk networks can be and are used in homes, schoolrooms, small offices, and conference rooms. In short, AppleTalk is successful in environments where IP networks have been absent, since IP networks have been too complicated and costly to administer. One advantage AppleTalk has over IP is that it functions even in networks where no services have been deployed.
As computers become cheaper and more pervasive, the obvious thing to do is network them together. Many companies are investigating adding features to their products to allow communication between consumer electronics, home appliances, personal computers, telecommunications devices, and more. Until the IP suite becomes as easy to operate as the AppleTalk Protocol Suite, the notion of a networked home or office using IP is impractical. There are many new networking protocols that offer easy deployment (for devices using that technology) in very simple network topologies. This diversity complicates the integration of communicating entities into a single network -- precisely what the IP suite is supposed to achieve.
Several computer software companies have taken the initiative to enhance the IP suite to address this challenge. The IETF has begun work on zero configuration networking for IP. The goal is to allow hosts to communicate using IP without requiring any prior configuration or the presence of network services. True to the traditional architectural principals of the IP suite, care is being taken to ensure that zero configuration networking protocols and operation do not detract from the scalability of larger configured networks with fully administered services.
This paper discusses the services and configuration essential for IP networking and surveys the IP suite standards for providing configuration to IP-enabled devices. The central topic of this paper is the emergence of protocols for operation without services or configuration. Work in the area of zero configuration protocols has been motivated by new demands in the marketplace. Some architectural principles are generally agreed upon and under gird the development of standards in this area. Finally, the paper summarizes the status of this work and concludes by discussing implications for the future.

Reverse Engineering Techniques
Reverse Engineering Techniques
INTRODUCTION:
Reverse engineering is the process of analyzing a subject system to identify the system’s components and their interrelationships and create representations of the system in another form or at a higher level of abstraction. The purpose of reverse engineering is to understand a software system in order to facilitate enhancement, correction, documentation, redesign, or reprogramming in a different programming language.

RESOURCE SHARING ON INTERNET
RESOURCE SHARING ON INTERNET
Introduction:
It is commonly observed that the continued exponential growth in the capacity of fundamental computing resources — processing power, communication bandwidth, and storage is working a revolution in the capabilities and practices of the research community. It has become increasingly evident that the most revolutionary applications of this superabundance use resource sharing to enable new possibilities for collaboration and mutual benefit. Over the past 30 years, two basic models of resource sharing with different design goals have emerged. The differences between these two approaches, which are distinguished as the Computer Center and the Internet models, tend to generate divergent opportunity spaces, and it therefore becomes important to explore the alternative choices they present as we plan for and develop an information infrastructure for the scientific community in the next decade.
Interoperability and scalability are necessary design goals for distributed systems based on resource sharing, but the two models we consider differ in the positions they take along the continuum between total control and complete openness. The difference affects the tradeoffs they tend to make in fulfilling their other design goals. The Computer Center model, which came to maturity with the NSF Supercomputer Centers of the 80s and 90s, was developed in order to allow scarce and extremely valuable resources to be shared by a select community in an environment where security and accountability are major concerns. The form of sharing it implements is necessarily highly controlled – authentication and access control are its characteristic design issues. In the last few years this approach has given rise to a resource sharing paradigm known as information technology “Grids.” Grids are designed to flexibly aggregate various types of highly distributed resources into unified platforms on which a wide range of “virtual organizations” can build. By contrast, the Internet paradigm, which was developed over the same 30 year period, seeks to share network bandwidth for the purpose of universal communication among an international community of indefinite size. It uses lightweight allocation of network links via packet routing in a public infrastructure to create a system that is designed to be open and easy to use, both in the sense of giving easy access to a basic set of network services and of allowing easy addition of privately provisioned resources to the public infrastructure. While admission and accounting policies are difficult to implement in this model, the power of the universality and generality of the resource sharing it implements is undeniable.
Though experience with the Internet suggests that the transformative power of information technology is at its highest when the ease and openness of resource sharing is at its greatest, the Computer Center model experiencing a rebirth in the Grid while the Internet paradigm has yet to be applied to any resource other than communication bandwidth. But the Internet model can be applied to other kinds of resources, and that, with the current Internet and the Web as a foundation, such an application can lead to similarly powerful results. The storage technology developed is called the Internet Backplane Protocol (IBP), designed to test this hypothesis and explore its implications. IBP is our primary tool in the study of logistical networking, a field motivated by viewing data transmission and storage within unified framework.

Real Time Streaming Protocol (RTSP)
Real Time Streaming Protocol (RTSP)
Abstract:
The traffic in the internet is becoming more and more involved with multimedia applications. To cope with such bandwith-demanding data, specific protocols have been created. The most difficult area is realtime (or realtimish) streams that enable us to make such things as videophonecalls and remote groupworks in much more efficient way.
The Real Time Streaming Protocol, or RTSP, is an application-level client –server protocol for control over the delivery of data with real-time properties.
RTSP provides an extensible framework to enable controlled, on-demand delivery of real-time data, such as audio and video. Sources of data can include both live data feeds and stored clips.
This protocol is intended to control multiple data delivery sessions, provide a means for choosing delivery channels such as UDP, multicast UDP and TCP, and provide a means for choosing delivery mechanisms based upon RTP.
The protocol defines the connection between a streaming media client and a streaming media server, and also provides a standard way for clients and servers from multiple vendors to stream multimedia content.
It takes advantage of Internet and Intranet infrastructure such as IP Multicast, RTCP and RTP, providing a means for choosing delivery mechanisms
