Abstract: Metal matrix composites (MMC) have become leading materials in aerospace and automobile industries and particle reinforced aluminum MMCs have received considerable attention due to their excellent mechanical properties like hardness, high tensile strength etc. These materials are difficult to machine because of high hardness and abrasive nature of reinforcing elements like silica particles. The aim of this project is to improve the machinability of particle reinforced MMC with the addition of the solid lubricant graphite. Here 15% by weight of the silicon carbide particle with 5% by weight of the graphite particle are added to the aluminium alloy. This is known as hybrid metal matrix composite. To fabricate this, stir casting technique is used. After that, the machining parameter (tool force, tool wear, and surface roughness) in milling for various speed, feed, depth of cut and mechanical properties (impact strength, hardness, flexural strength) of the composite is checked and to optimize the machining parameter, Taguchi technique with L27 orthogonal array is used.

Abstract: An online Query based searching involves mainly two methods of retrieving the data from the database. (1)Top-k query (2) Skyline query. The ranking rule methodology is used in Top-k query whereas dominance relationship is used in skyline query. Top-k dominating query used to search and retrieve the K records with highest dominance results either by ranking and dominance relationship method in static database. The Continuous Top-k Dominating query (cTKDQ) method has some limitations. In order to overcome the existing demerits, introduces a new indexing structure called close dominance graph (CDG) to support and maintain the relationship between dynamic data records. However, CDG as it takes more time to search results. In this paper introduce a dictionary based compression algorithm, which is efficient in answering a cTKDQ with minimum time and memory. The experimental results have shown that this scheme is able to better performance when compared with other prevailing scenarios.

Abstract: As computer systems create and collect growing amounts of data, analyze it becomes a basic part of improving the services provided by Internet companies. A vital property of the workloads method by Map Reduce applications is that they are often incremental by nature; i.e., Map Reduce jobs often run frequently with small changes in their input. In this paper, explain the architecture, implementation, and evaluation of a vital Map Reduce framework, named I2 map reduce framework, for incremental computations. I2 map reduce notice changes to the inputs and allow the automatic update of the outputs by employing an efficient, fine-grained result re-use mechanism. To attain efficiency without give up transparency, accept recent advances in the area of programming languages to identify methodically the shortcomings of task-level memorization approaches, and address them using numerous novel techniques such as a storage system to store the input of consecutive runs, a reduction phase that make the incremental computation of the reduce tasks more efficient, and a scheduling algorithm for Hadoop that is aware of the location of previously computed results.

Abstract: Friction stir spot welding is a solid state material joining technique which has been receiving worldwide attention due to its ability to join dissimilar materials without difficulty. In this investigation, friction stir spot welding technique was used for joining dissimilar combinations of aluminum alloy Al 5083 and commercial copper C10100. The joints were fabricated within feasible limits of friction stir spot welding process parameters such as tool rotational speed, dwell time and plunge depth. The effect of variation in duration of dwell which is one of the significant process parameters affecting the joint properties was analyzed. The tensile strength of the joint was measured using tensile shear failure tests and the interface micro hardness was measured using Vickers hardness testing equipment. The variations in joint characteristics with respect to changes in dwell time were analyzed so as to achieve strong joints.

V.P. Sakthivel | pp: 45-50 | Purchase PDF
Abstract: This paper presents the application of a new metaheuristic optimization algorithm, an ameliorated particle swarm optimization (APSO) algorithm for solving the economic load dispatch (ELD) problem involving a number of equality and inequality constraints such as power balance, prohibited operating zones and ramp rate limits. The APSO algorithm, a variant of the basic PSO algorithm, is obtained by incorporating chaotic sequences to enhance its performance. Two different example problems comprising six and fifteen generating units are solved to demonstrate the effectiveness of the algorithm. The results of APSO are compared with GA and PSO techniques. The simulation results show that the APSO methods have good convergence property. The generation costs obtained by APSO method are lower than those of the traditional PSO algorithm, and hence, APSO method can result in great economic effect. For ELD problems, the APSO method is more feasible and effective alternative approaches than the traditional PSO algorithm.
