-Rahulkumar B. Chaudhary ; Prof. V. D. Patel; Prof. Priyesh N. Santoki
The development of new materials shows the immense growth but the major problem, it is very difficult to machine the newly developed materials. So it is necessary to adopt some new machining methods. Electrical Discharge Machining (EDM) is a non-traditional and most popular machining method to manufacture dies, punches and press tools because of its capability to produce complicated, intricate shapes and to machine hard materials. Electrical Discharge Machining performance is generally evaluated on the basis of Overcut (OC), Material Removal Rate (MRR), Tool Wear Rate (TWR) and Surface Roughness (SR). The important EDM machining parameters affecting to the performance measures of the process are discharge current, pulse on time, pulse off time, arc gap, and duty cycle. Several approaches are proposed in the literature to solve the problems related with optimization of these parameters. It is felt that a review of the various approaches developed would help to compare their main features and their relative advantages or limitations to allow choose the most suitable approach for a particular application and also throw light on aspects that needs further attention. In view of above, this paper presents a review of Effect of Electrode Material on Overcut, MRR, TWR of Steel Material in EDM. Read More...

The Surface roughness is one of the most commonly used criteria to determine the quality of milled steel and it is affected by various cutting parameter such as depth of cut, cutting speed and feed rate. Surface roughness is an important parameter for quality of product such as aerospace, automobile and mold dies etc. Some standard tools and techniques are required for the analysis of cutting parameter to get the optimum results. Surface roughness contributes to better function or longer life span. It also contributes to abrasion resistance materials and good wear resistance. Hence Taguchi method or cutting parameter design approach is used. The aim of the project is to optimize the cutting parameter such as feed rate, depth of cut and cutting speed for End milling process of P20 steel. P20 steel which is used for making molds and dies requires excellent surface finish. This can be achieved by Taguchi method aiming to increase the surface finish and reducing production cost. Taguchi method is powerful tool to design a process. It can be used to find optimal condition for the operation. This optimized cutting parameter can be used for End milling process to achieve better surface finish. Read More...

A Survey on Image Retrieval Techniques for Capturing User Intention
-Pooja S.Junonkar
Web search engines are been used in large scale for image retrieval. Largely used web-search engines (like Google, Bing, iLike, etc) mostly rely on various based image search. User enters a query in this search engines and gets images as result. This provides us with random and noisy results as outcome. This search does not provide user’s intent result. User has to go through all the obtained images and select the required image suitable to user’s intention. These increases complexities for users. To overcome these complexities many of the different image techniques are researched. Some techniques are textual-based, some are color-based and some are shape-based, while some may be the combinations of above all techniques. Some techniques search images online, while some searches offline. But the intension of all the techniques is to capture user’s intention. In this paper, we present a novel internet image search approach. This paper contains an efficiently proven profitable technique for capturing user’s intention. In the further context, we discussed various techniques of image search for efficient image retrieval in short. Read More...

Effect of Aspiration Pressure on Convergent nozzle employed for gas atomization of Liquid Metals
-Sanjay Phatige ; T.N. Srinivasa
Atomization is often chosen as one of powder production techniques because of high production rates and ability to make alloy powders of desired composition. In gas atomization process, liquid metal is broken into droplets to form powders upon solidification. Gas-metal interaction influences the break-up of liquid stream into droplets. The idea is to transfer kinetic energy from a high velocity jet-gas expanded through a nozzle, to a stream of liquid metal, resulting in fragmentation and break up into metal droplets. Gas atomization process is one of the widely used powder production technique and nozzles play an important role in the gas atomization process. The geometry of nozzles governs the gas to metal interaction. The selection of nozzle type and the flow geometry is the most important preset parameter for atomization process. The design of an atomizing nozzle determines degree of contact of liquid metal with the atomizing gas. Aspiration pressure is the optimum pressure developed at tip of the nozzle (at atomization zone) which will favor gas atomization process. In the present analysis, an attempt was made to analyze effect of atomization pressure and aspiration pressure for Convergent nozzle (C-nozzle) employed for gas atomization process using Computational Fluid Dynamics (CFD) techniques Read More...

A literature review on Process parameter optimization of Powder Mixed Electric Discharge Machining (PMEDM) using design of experiment
-Irshad Shaikh ; Wasim Khan; Arun Kumar
EDM is a non- conventional machining process in which the material is removed by erosive effect. Arc is established between the electrode and tool both should be electrical conductive. There is no direct contact between the two. It is useful for machining hard, difficult to machine materials such as heat resistant alloys, super alloys and carbides which can’t be easily machined with conventional once. Its unique feature of using thermal energy to machine electrically conductive parts regardless of its hardness. It is commonly used in mould, die making industry and in manufacturing of automotive, aero-space surgical components. However, EDM suffers few limitations such as low machining efficiency and poor surface finish. To overcome these limitations the electrically conductive powder particles are mixed in the dielectric fluid, which reduces its insulating strength and increases the spark gap distance between the tool and workpiece. This new hybrid material removal process is called Powder mixed EDM (PM-EDM). From the point of view of industrial applications, die steel is a very important material and that’s why for the purpose of experimentation D3 die steel with copper electrode and IPOL oil as dielectric has been used. PMEDM is very complex in nature and controlled by a large number of parameters, which are having impact on various responses. The present study is an attempt to investigate the potential of PMEDM for increasing material removal rate (MRR), decrease in tool wear rate (TWR) with improved surface roughness (SR) of Die steel. In previous research work Kerosene is used as dielectric fluid. Kerosene has adverse impact on the environment as well as health of the operator. So in this experimental method commercially available EDM oil will be used. The research outcome will identify the important parameters and their effect on material removal rate (MRR), tool wear rate (TWR) and surface roughness (SR) in the presence of suspended powder in a IPOL oil as dielectric of EDM. Experiments is designed using Design of Experiment so that effect of all the parameters could be studied with minimum possible number of experiments. Results of the experimentation is analyze analytically as well as graphically using ANOVA and main effect-interaction plots, respectively. ANOVA has determined the percentage contribution of all factors upon each response individually. Read More...

DREAMS: Run-time Partitioning Skew Mitigation
-Rutul D. Dhomse ; Prof. R.N.Phursule
MapReduce has turned into a mainstream model for largescale information handling as of late. Be that as it may, existing MapReduce schedulers still experience the ill effects of an issue known as parceling skew, where the yield of guide errands is unevenly dispersed among diminishes undertakings. In this paper, we introduce DREAMS, a structure that gives run-time apportioning skew alleviation. Dissimilar to past methodologies that attempt to adjust the workload of reducers by repartitioning the transitional information allotted to each lessen errand, in DREAMS we adapt to parceling skew by changing assignment run-time asset designation. We demonstrate that our methodology permits DREAMS to take out the overhead of information repartitioning. Through trials utilizing both genuine and engineered workloads running on a 11-hub virtual virtualized Hadoop group, we demonstrate that DREAMS can adequately moderate negative effect of dividing skew, in this way enhancing work execution by up to 20:3%.

-Agnish N ; Dr.R.Malayalamurthi
Biodiesels obtained from vegetable oils and animal resources have been considered as a promising alternate fuel. Many researches were performed blending diesel with single biodiesel. Only very few works were done with the combination of two different biodiesel blended with diesel. In this experimental study, two Biodiesels from Palm oil and Rice Bran oil blended with Diesel at various mixing ratio (PME10, RBME10) and (PME20, RBME20). The fuel properties of the blends were tested for its acceptance in accordance with ASTM standards. The performance tests were done with two blends (10% & 20%) at various loads with constant engine speed of 1500 rpm and the results were compared. The performance characteristics observed for 10% blends are similar to that of diesel. The Brake power and Brake thermal efficiency are higher for 10% blends compared to 20% blends however the Brake specific fuel consumption of 10% blends are lower than that of 20% blends. This experimental analysis reveal that the combined blend of PME10 & RBME10 shows superior performance than the blend of PME20 & RBME20. Read More...

-Jadhav Shweta Dinkar ; Prof. N. M. Shahane
Content Based Image Retrieval has drawn attention in last few years. CBIR is used for retrieving images from the large scale. Without the use of compressed code for image retrieval large scale of images cannot be searched expeditiously. Bag-of-Words BoW is not realistic for huge image database because it is concentrated in memory. The main objective is to achieve high performance and lower memory cost. The new framework Mixture of Subspace Image Representation is used. In this local descriptor is modelled for each image present in the database. A query image is given to the system is matched with the image present in the database and the likelihood function is computed. It is found out through the review of papers that the new framework represents every database image in a small amount of number of bytes which achieves good performance than the state-of –art. The memory required to store the data is more so the new framework is proposed. So that they require the less memory and improved performance of retrieval. The retrieval performance is improved because of the reduction of the large scale database. Read More...
