Authors	:	B.Santhosh Shanmuga Pandian. Dr R.Kesavan

Abstract: The job-shop scheduling is one of the useful techniques for solving optimization of problems. Flexible job-shop scheduling problem is an alternative tool of the job-shop problem that allows a process to be carried on by the machine from the given alternative ways. There are available many algorithms to solve the flexible job-shop scheduling problems. The aims are to minimize the overall completion time (makespan), the total workload of machines and the workload of the most loaded machine. It also minimizes the manufacturing cost. Genetic Algorithm and particle swarm optimization are implemented to solve the multi-objective flexible job-shop scheduling problem. Both are population based algorithm, we compare the performance of these algorithms to achieve an optimal or near optimal solution. It is concluded that the particle swarm optimization algorithm gives promising solutions. The excellence of solution achieved by particle swarm optimization algorithm is greater to that of the genetic algorithm, but the genetic algorithm takes shorter time to find a schedule solution.

Abstract: The In engineering design, a best possible design is achieved by comparing alternative design solutions by using previous problem information. Optimization algorithms provide systematic and efficient ways of creating and comparing new design solutions in order to achieve an optimal design. An optimum design is to minimize the various undesirable values and to maximize the most significant enviable effect. Optimization plays an imperative role in various engineering applications. In order to increase the design efficiency and get the most excellent design effect, in this paper a gear drive is considered as an application and novelty of the evolutionary algorithm evaluated through this gear drive. Gearbox is an universally used mechanical element in a variety of area likes automobiles, machine tools and aircrafts etc. The major problem for the mechanical engineer is in the field of design and innovation. Gearbox design can be defined as the selection of material and geometry, which satisfies individual and implied efficient requirements. In this paper, a two stage spur gear box is considered with maximization of power and efficiency, minimization of weight and centre distance as objective functions with design stresses as constraints. The above problem is optimized with a new population based evolutionary algorithm and results are compared with existing design.

Title	:	Analysis of Brake Thermal efficiency and Oxygen in exhaust using oxygen enriched air in Compression Ignition engine.
Country	:	India
Authors	:	Bharath.P . Kamalakkannan.K

Abstract: Pollution is one a major factor which affects the environment nowadays, resulting in green house effect and global warming. One way of increasing efficiency is by inducting oxygen into the combustion chamber since oxygen is a combustion enhancer the amount of oxygen entering into the combustion chamber if increased it would result in better engine performance and lower emissions. Oxygen can be inducted in the intake manifold by the help of an external source. This additional increase of air will affects all parameters of the engine like Brake power, emissions, and heat release but we are going to consider only Brake thermal efficiency and Oxygen in the exhaust. Load test was conducted on a compression Ignition engine for various concentration of oxygen from (21% to 27%) with an interval of 2%. This analysis shows better Brake thermal efficiency and better brake specific fuel consumption but led to a very high percentage of Oxygen in the exhaust and lower carbon monoxide (CO), hydro carbon(HC) emission..

Abstract:Nowadays Robots play a vital role in all the activities in human life including industrial needs. In modern industrial manufacturing process consists of precise and fastest proceedings. Human operations are needed to perform a variety of tasks in a robotic system such as set-up, programming, trouble shooting, maintenance and error handling activities. Hazardous conditions exist when human operators intervene into the robotic work zones. Human perception, decision making, and action strategies need to be studied to prevent robot-related accidents. System designers and technology managers are required to consider the limitations of operator perceptual process in design and layout of robotic system. The ultimate object is to save human lives in addition to increasing productivity and quality of high technology work environments. Effective safety training programs for work with industrial robots should be developed. The objective of this project is to design, analysis of a Generic articulated robot Arm. Articulated robot has been noted for application in traversing and performing manipulation in nuclear reactor facilities. Some aspects of the articulated Robot that are anticipated as useful are its small cross section and its projected ability to change elevation and maneuver over obstacle. The small cross section and the loads associated with suspension of the Robot while changing elevation or maneuvering over obstacles require large joint torque to weight rations for joint actuation. A novel joint actions actuation scheme is described and its implementation detailed in this project.

Title	:	EMISSION ANALYSIS OF DI-DIESEL ENGINE AT DIFFERENT INJECTION PRESSURES USING JATROPHA AND RUBBER SEED OIL BLENDED WITH DIESEL
Country	:	India
Authors	:	S. Mahalingam. ,B.R.RameshBabu . B.Balaji

Abstract: Biodiesel as a renewable fuel has been considered as the best alternate for diesel fuel now a days. This fossil fuel can be used in diesel engine with or without any modification.The injection pressure and injection timing are the major influencing parameters for the performance and emission of diesel engine. In this present study, the emission analysis of vegetable oil, Jatropha oil and rubber seed oil crushed from the seed, esterified and blended with pure diesel fuel. A single cylinder constant speed direct injection (DI) diesel engine has been used to analyze the emission characteristics of biodiesel. The diesel engine for various fuel injection pressures (210,220 and 240 bar) at no load to full load was investigated. The injection pressure was changed in the engine head by adjusting the fuel injector spring tension. The two proportions of biodiesel were used in diesel engine such as 20% of biodiesel (Jatropha oil and Rubber seed oil) with 80% of pure diesel fuel named as B20 and 40% of biodiesel with 60% of pure diesel fuel named as B40.From the test result, the nitric oxide (NOx) was analyzed for different injection pressures. In emission characteristics analysis, it was found that the increase in injector opening pressure increases the NOx emission. The injection pressure of 240 bars and B20 proportion gives better emission reduction compared to other blended fuels.
